May the world no longer be "orphaned" and the "reunion" action in Ningxia reunite 46 separated families.

After Guo Gangtang, the prototype of the movie "Lost Orphan", successfully recognized his relatives in July this year, Sun Haiyang, the prototype of the movie "Dear", also achieved a reunion on December 6, and met Sun Zhuo, his son who had been abducted for 14 years. The unexpected reunion in the movie has come true in reality, and such a touching story is also happening in Ningxia …

Since January this year, the Ministry of Public Security has deployed a nationwide "reunion" campaign. Ningxia Public Security Department, in combination with the study and education of Party history and the education and rectification of the political and legal team, clearly requires that the work of helping parents find their children’s "reunion" be a political task, so as to make the road of recognizing relatives shorter. As of December 13th, 46 separated families have been reunited, and 17 abducted or lost children in Ningxia have been recovered.

After 61 years of reunion.

"I’m so happy. I’ve been listening to my parents for a lifetime since I was a child, and I finally found it. Thanks to the comrades of the public security police, the parents’ wishes have finally been realized. " In June this year, 61-year-old Ge Jianchun, accompanied by the police of the Criminal Investigation Detachment of Yinchuan Public Security Bureau in Ningxia, and his family drove more than 640 kilometers from Yinchuan to Taibai County, Baoji City, Shaanxi Province, to reunite with his second brother Ge Minsheng who had been separated for 61 years.

This time, the road for brothers to meet each other has gone for 61 years.

Ge Jianchun recalled that in 1960, due to the work of his father Ge Yangqing, his parents separated the two places. The pregnant mother Tang Lanying took the eldest son Ge Ansheng and the second son Ge Minsheng and took the train from Lanzhou, Gansu Province to Xi’ an, Shaanxi Province. At that time, the environment on the train was noisy and there was a large flow of people. Tang Lanying had to be distracted to take care of two children. At that time, he accidentally lost Ge Minsheng. For 61 years, the family has never given up looking. This year, finally found it.

"Take off your socks and let me see." Ge Jianchun said this when the two brothers just met at the scene. Seeing that Ge Minsheng’s little toe exposed after taking off his socks has two petals of nails, he immediately choked and hugged him and said, "Yes, you are my brother, and our family’s nails are like this."

Ge Minsheng came to Yinchuan with his family during the "Eleventh" holiday this year. "Before my parents died, I was obsessed with my second brother, and my greatest wish was to find him. Now that our family is reunited, I believe they must be very pleased. " Ge Jianchun said. "After the holidays, our big family has become more lively."

Recognizing the "gold standard" is the final word.

Ge Minsheng, an old man who has been lost for 61 years, recognizes relatives with his family, which is the longest successful case of finding relatives in Ningxia since the reunion operation. DNA test, known as the "gold standard" for identifying kinship, is the decisive factor for the success of this search.

In the centralized comparison battle of criminal technology in the "Reunion" operation, through the sharing of national data resources, Zhou Dong, the second-level director of police technology in the Criminal Technology Department of Ningxia Public Security Department, found an important clue: Zhang Moumou (44 years old), a man in Taibai County, Baoji City, Shaanxi Province, was highly suspicious compared with Ge Shengyang, who was looking for relatives, and needed further verification. After learning this important clue, the police of Yinchuan Public Security Bureau immediately contacted Baoji Public Security Bureau of Shaanxi Province. With the help of local police, after some work, they successfully compared Zhang Cheng (66 years old), the father of Zhang Moumou, and identified him as Ge Minsheng, a child who disappeared 61 years ago.

"The comparison process is really tortuous. Although I keep failing, I always cheer myself up and try again. I am very excited at the moment of success." Zhou Dong explained that in theory, if there are DNA samples of parents and children in the abduction database, the system can automatically conduct accurate comparison. However, the reality is often complicated, which requires technicians to manually screen and compare from massive data.

After witnessing the recognition scene of the Ge brothers, Zhou Dong was deeply touched. "For a family, the loss of children and their relatives have a great influence. I am proud that my work can help make up for their regrets." Zhou Dong said.

In May this year, in order to carry out the "Reunion" operation in depth, the criminal investigation department of Ningxia Public Security Bureau set up 25 free blood sampling points for the "Reunion" operation in the whole region, and at the same time collected blood samples of unidentified persons and lost persons, tested DNA and entered them into the national abduction database.

"Thanks to the continuous expansion of the abduction database and the progress of DNA detection technology, the accuracy and efficiency of DNA comparison have improved, providing technical support for the’ Reunion’ action in Ningxia." Wang Yuru, the second-level director of police technology at the Criminal Technology Department of Ningxia Public Security Department, said.

Looking for clues in the world

In the process of finding relatives, the work of criminal investigation police is also very important. In the case of insufficient conditions for DNA identification samples, they need to look for clues in massive information; It is also necessary to organize family recognition, and cooperate with civil affairs, women’s federations and other relevant departments after family recognition to help abducted and missing persons integrate into their families and society.

In 2007, Zhang, who lives in Zhongwei, left home because of employment pressure and inner confusion, and has not heard from him since then. In the past 14 years, the Public Security Bureau of shapotou district, zhongwei attached great importance to it, and was responsible for the police to look for clues from the massive information and go to many provinces, cities and counties to check the clues.

On September 20th this year, when the "Reunion" special class of the Criminal Investigation Brigade of shapotou district Public Security Bureau combed the relevant information, it was found that the ID number of the missing person Zhang was the same as that of a man registered by the Shanghai Public Security Bureau in December 2020. After learning this information, Wu Haiyang, deputy head of the Criminal Investigation Brigade of the Bureau, actively docked with the Shanghai public security organs to find the blood card collected by the man during registration for DNA identification. After identification, the man and the Zhang couple are in line with the parent-child genetic relationship. Wu Haiyang and his colleagues immediately went to Shanghai to look for Zhang.

After arriving in Shanghai, with the support of the Criminal Investigation Bureau of Shanghai Public Security Bureau and Yangpu Branch, Zhang’s whereabouts were found. Wu Haiyang took out the photos and videos of his family life taken in advance, which were compared and confirmed by Zhang, and told him about the recent situation at home, and finally successfully persuaded Zhang to return to his family.

"As a policeman, it is commonplace to run around, but I feel that it is worthwhile to see their family reunited again." Wu Haiyang said.

It is understood that this year, the Ningxia Public Security System comprehensively sorted out the cases of local children being abducted since the reform and opening up, filed cases by case, re-examined the papers and found the families of abducted children to understand the situation, deeply searched for clues to solve the case, used new means of investigation, and used big data resources to tap the breakthrough point of solving the case. Check the incident one by one, re-study the nature, re-sort and judge the relevant information of suspicious persons suspected of trafficking crimes, and carry out the work of merging cases and digging deep into the remaining crimes. Among them, in February this year, the abduction case of Lin Mohao in zhongwei, which was supervised by the Ministry of Public Security, was successfully detected, the abducted child Lin Mohao was rescued, and three suspects were arrested, which achieved good social effects.

"We organized a number of police types to simultaneously file cases and work in the same direction, carried out joint consultation and judgment, and integrated technologies such as big data judgment and DNA testing and identification, actively explored, summarized and refined a series of effective technical warfare methods." Wang Cheng, the detachment leader of the Ningxia Criminal Investigation Corps and the head of the "Reunion" action class, said.

In the next step, the criminal investigation department of Ningxia will thoroughly practice the people-centered development thought, continue to carry out the practical activities of "I do practical things for the masses", use traditional and new media propaganda methods to deeply mobilize the support and participation of all sectors of society and the masses, and make in-depth use of data screening and comparison, criminal technology inspection and identification and other measures to let more missing abducted children, suspected abducted people and unidentified people go home for reunion.

Standardize the behavior of vehicle rescue service, and shall not force the designation of rescue agencies, and shall not hinder or prevent the third-party rescue agencies entrusted by the parties from entering the site for service.

  (3) Strengthen passenger health services. Passenger stations, expressway service areas, and "driver’s home" business units should strengthen the reserves of medicines such as fever medicines, cold medicines, and first-aid medicines. If conditions permit, they can set up "health stations" or medical service points, and open up separate rest places to provide more warm family services for truck drivers and passengers in need.

  (four) to ensure automobile maintenance services. Advocate the normal operation of Class I and Class II automobile maintenance enterprises and Class III engine specialized enterprises during the Spring Festival holiday. We can guide employees to provide convenient and fast auto repair services for car owners by taking turns to work and issuing overtime subsidies.

  (five) to do a good job in the detention of personnel services. Where people are stranded on expressways, service areas and passenger stations, relevant business units will intensify service guarantee and provide hot water, food and necessary health services for the stranded people in time.

Causes and countermeasures of low influent concentration in urban sewage treatment plants

The influent quality is an important basis for determining the process flow of sewage treatment plant, and is the main parameter for accounting the actual emission reduction, which directly affects the construction cost and operation cost. till/extremely2014A sewage plant was built in the urban area of a city in, with a designed treatment capacity ofeightten thousandm3,And equipped withfiveA lifting pumping station;The main purpose of the sewage treatment plant is to play an important role in reducing the total emission of major pollutants in the region. However, with the official operation of the sewage treatment plant, a series of problems are gradually exposed.,One of the most important problems is water inflow.CODThe concentration is generally low. In view of this situation,The author makes an investigation and analysis.,The following results are obtained.

oneMethods and contents of investigation

Collect information.Contact relevant units to collect relevant information and understand the relevant situation.,Including the design and completion drawings of drainage pipe network in the service scope of sewage plant, urban population, meteorological climate and other information.;Drainage system adopted by the city, groundwater situation and pipe network maintenance, etc. Analyze the pipe network diagram in detail,Determine the sampling point in combination with field investigation.

Carry out major pollutants on each drainage unit, including domestic sewage raw water, sewage interception head, branch pipes at all levels, sewage pumping station, etc.CODSampling monitoring of concentration.Select representative residential areas to investigate the treatment efficiency of septic tanks and the situation of residents’ own water.

Investigate and analyze the regional drainage pipe network, including sewage pumping station and sewage interception engineering pipe network.According to the population and water consumption units in the service range of the pipe network, the theoretical displacement is estimated and compared with the actual displacement in the measured range to determine the pollution acceptance rate of the drainage pipe network.

Find out the specific location where the external water source enters the pipe network, and record its flow andCODConcentration, and continuous monitoring for many days.

According to the experimental results and collected data, the causes of low influent concentration in sewage plants are analyzed and summarized, and targeted suggestions and rectification measures are put forward.

2Present situation of actual inlet water quality of water supply and drainage and sewage plant in a city

According to the survey, the average water consumption of urban residents in this city is8.91ten thousandm3,The peak period of water use can reach near9.7ten thousandm3. Its drainage system is mainly intercepting combined system. The sewage treatment plant reflects the basic situation of the water quality of the sewage treatment plant on that day with the mixed samples of the early, middle and late inflow. Through the mixed inlet water of the sewage treatment plant in the morning, the middle and the eveningCODMonitoring the concentration, and obtaining the change diagram of the inlet water quality, as shown in the figure.l.

pictureoneVariation diagram of influent concentration of sewage treatment plant

Youtuoneknowable,The influent concentration of sewage treatment plant is mainly concentrated in80~100mg/L,In a long-term low state, far from reaching the design value.300mg/L.

threeInvestigation on background value of municipal domestic sewage

The residential areas with concentrated residents, administrative center areas, representative commercial dining areas, hotel-intensive areas and hospital sewage were selected as the investigation objects of urban domestic sewage background value. The monitoring results are shown in the table.one.

tableoneMonitoring results of background value of municipal domestic sewage

YoubiaooneAccording to the monitoring results in.,The concentration of sewage in residential areas and commercial dining areas is relatively high, while the concentration of sewage in hospitals is low, and the concentration of sewage in municipal central areas is similar to that in hotel-intensive areas. Calculate the domestic sewage according to the proportion of various domestic sewage.CODThe weighted average concentration is189.34mg/L.

fourcause analysis

4.1Problems of drainage system

The new urban area of this city adopts the complete rain and sewage diversion system.,However, the main sewage pipe has not yet been built.,Sewage can only be combined with rainwater pipes and discharged into the nearest river channel.,Polluted water environment;The drainage system in this city is mainly the combined system of rain and sewage. At present, the old city is still using the way of collecting sewage by culvert instead of pipeline. In addition, the city has a subtropical monsoon humid climate, with frequent rain and heavy rainfall in the rainy season. In recent years, the average annual rainfall in this city is about1800mm,This greatly increases the dilution effect of rainwater on sewage concentration. It can be seen that the rainwater and sewage confluence system has a great influence on the influent concentration of sewage plants.

4.2Exogenous lowCODInfluence of concentrated water source entering sewage pipeline

During the investigation, it was found that there were many foreign water sources entering the sewage pipe network in the whole sewage pipe network collection system. These foreign countries are lowCODConcentrated water sources include river water, swimming pool water, construction water and groundwater. The survey results show that the average amount of water flowing from the inner river into the pumping station reaches2.
2
ten thousandm3,About the total sewage volume1/4,thatCODThe average concentration is60mg/L; There are small and medium-sized swimming pools in many communities in the city, and the water replaced by them is basically discharged into the urban sewage pipeline, just like the water used for construction.,These all feed the sewage plant.CODThe concentration has a certain impact.;Located in the south bank of the middle reaches of the Yangtze River, the city is rich in water resources and has a high groundwater level.,However, most drainage pipes are made of concrete pipes, even rigid joints in the old city. Therefore, groundwater and surface water can easily penetrate or flow into the drainage pipe network.,The concentration of sewage is dilute.

4.3Problems of septic tank setting

Septic tank is a simple decentralized facility for primary sewage treatment, which can play a certain role in sewage treatment. Therefore, when there is no sewage treatment plant in the urban area, septic tanks are built in many residential areas to treat domestic sewage.,To some extent, it can reduce the pollution of water. But after the sewage treatment plant was established,,The pipe network collected the sewage pretreated by septic tanks.,It also directly reduces the amount of sewage entering the sewage treatment plant.CODConcentration. The survey results show that the septic tank treatment efficiency of the whole residential area in this city is as follows35%about,Finally, the supernatant of septic tank is discharged into the sewage pipe network.

4.4Low pollution acceptance rate

Since the establishment of sewage treatment plant in this city,The laying of urban drainage pipe network is relatively backward.,Domestic sewage in many areas can’t be effectively collected to the main sewage pipe and discharged to the sewage treatment plant. In the urban area, some main pipes are still idle and not connected to the main pipe, and sewage collection pipes are not laid in many areas, thus reducing the effective collection area of the drainage pipe network and the low pollution acceptance rate. In some areas of the city, the main sewage is directly discharged into the nearby water body, so the amount of sewage to be treated cannot be reached.,The phenomenon of pumping river water to pretend to be treated, which not only leads to the low pollution acceptance rate of sewage plants and the low influent concentration, but also causes the pollution of environmental water bodies, which does not reflect the value of building sewage plants at all.

4.5Residents’ water use habits

With the continuous improvement of the city’s water supply system and the continuous improvement of residents’ living standards, the city’s water price is low and local residents’ awareness of saving water is not strong.,As a result, the per capita water consumption has increased year by year. According to the survey, the increase of residents’ water consumption is mainly reflected in the increase of water consumption for bathing and washing.,The organic matter concentration of these domestic sewage is low, which will inevitably lead to the low influent concentration after entering the sewage plant.

fivecounter-measure

5.1Pay attention to the preliminary investigation and planning and design of urban drainage system construction

The basic data of urban drainage system planning and design is the decisive factor to evaluate the planning and design quality and social and environmental impact. The main basic data include the overall urban planning, existing urban drainage systems and facilities, local sewage irrigation, and the status quo of sewage reuse. If the sewage plant does not adjust the sewage quality in the collection area, the current sewage pipe network in the collection area, the population and water consumption in the sewage collection area, etc.

Check and design, which will lead to the uncertainty of the quantity and quality of water entering the sewage plant after its completion.

5.2Improve the drainage system

According to the national drainage code, "different drainage systems are allowed in the same town", the intercepting combined drainage system can be used for transition in the near future, and the separated drainage system can be gradually transformed with the urban construction in the long term, and the original rainwater and sewage combined pipe can be changed into a single rainwater pipe.,No longer connected to the intercepting main pipe, at the same time, the intercepting main pipe is used as the sewage main pipe and its overflow port is closed, and the sewage branch pipe is paved again to connect to the sewage main pipe, so that in the long run,

The rain and sewage are completely separated. The building density in the old city of this city is high.,The laying of pipe network is also complicated, and it is difficult to transform. Therefore, areas that are easy to transform, such as areas with low building density and low pipe network density, can be transformed into a complete rain and sewage separation system first, and then combined with the planning department.,For the old city which is difficult to transform, the drainage system is gradually changed to the rain and sewage complete separation system.

5.3Reduce external water sources entering the pipe network

During the investigation, it is found that the external water sources entering the pipe network in this city mainly include rainwater, river water (including a large number of internal rivers entering the collection pool of pumping stations) and groundwater. Therefore, measures should be taken as far as possible to reduce the entry of foreign water sources into the sewage pipe network, and even to prevent river water from entering the pipe network. In this regard, the following measures are proposed:①The main measure to prevent rainwater from entering the sewage pipe network is to gradually change the drainage system into the rain and sewage complete separation system.; ②For several drainage outlets connecting the sewage pipe network and rivers in the urban area, as well as culverts serving as sewage main pipes to collect domestic sewage, under the condition of not affecting flood discharge,,It can be blocked to prevent rainwater and other low-concentration external water sources from entering the pipe network.;For the overflow port where river water is easy to flow backward, a suitable flap can be installed to prevent it from flowing backward. (3) do a good job of leakage prevention and impermeability. When designing urban drainage network, we should investigate the groundwater and surface water conditions in various areas of the city.,In order to do a better job of leakage prevention and impermeability, so as to achieve the purpose that the influent concentration of sewage plant is least affected by the infiltration of groundwater and surface water.

5.4Gradually transform septic tanks

If there is no septic tank, feces and other debris will directly enter the sewage pipeline, which will easily cause pipeline blockage, so it is not recommended to completely dismantle the septic tank.,Considering the influence of septic tank on the influent concentration of sewage plant, it can be reformed. Most communities or buildings in this city are equipped with three-stage septic tanks, which have many stages and long sewage retention time.,To reduce the ability of septic tank to treat organic matter, the number of stages can be reduced, and the retention time of sewage and anaerobic digestion time can be shortened.,A simple precipitation effect can be achieved. Corresponding measures can be taken to reduce the number of septic tanks and reduce the volume of septic tanks.

5.5Improve the construction of sewage pipe network and improve the pollution acceptance rate

The problem that often exists in urban sewage plants is that although the sewage plants are completed and put into operation as planned, only part of the sewage main pipes and branch pipes are built in the sewage pipe network.,Not all the sewage in the planned area is collected, resulting in insufficient actual treatment capacity of the sewage plant and the phenomenon that the uncollected sewage is directly discharged into the river to pollute the environment. The sewage treatment plant in this city also has similar problems, so it is necessary to re-plan the drainage pipe network to fully connect with the old drainage system.,Try to ensure that all sewage in the planned area will eventually be discharged into the sewage plant.

5.6Strengthen residents’ awareness of water saving,Improve water use efficiency

The city is rich in water resources, the water price is not high, the residents’ water consumption is increasing year by year, and the habit of wasting water is also formed, so it is particularly important to strengthen the residents’ awareness of water saving. It is suggested to start from the following two aspects.:①Do a good job in publicity, encourage residents to save water, and encourage residents to use more water, such as collecting water for washing vegetables and bathing as toilet water. (2) adjust the water fee or the planned water consumption is the same as the fixed water supply, and control the water consumption of residents, so that residents can gradually form the habit of saving water.

Brief introduction of China Radio Drama Research Association

  On January 20th, 1933, the earliest recorded radio drama in China was published in Radio China magazine, with the title "Horrible Memories", which was written by Su Zugui. The drama was produced by Shanghai Radio Asia-America Company, and broadcast in the activities organized by Asia-America Broadcasting Company to raise funds to support the soldiers at the front line of the anti-Japanese war, which played a certain role in inspiring the anti-Japanese enthusiasm and fighting spirit of the broad masses of Shanghai people. 


  On February 7, 1950, in order to commemorate the "February 27" railway strike, china national radio produced a radio drama "10,000 pieces of plywood", which reflected the railway workers’ efforts to repair railways and support national construction. This was the first radio drama broadcast after the founding of New China. Later, there appeared the radio drama Pan Xiuzhi, which reflected the opposition to arranged marriage and advocated women’s liberation, and the radio drama Zoya-Jin Yuji, Picture Story and Night in Harbin, which were broadcast during the War to Resist US Aggression and Aid Korea.  


  From 1949 to 1954, the Radio Troupe of Shanghai People’s Broadcasting Station performed radio dramas such as Thanks to Stalin, Zou Yumei, and Three Thousand Li Jiang Shan. 


  In 1952, China introduced the tape recording technology from abroad, which made a turning point in the recording mode of radio drama, and the expression form of radio drama had greater insight, gradually matured in art and formed an independent art form. 


  In 1954, the Central Broadcasting Troupe was established, and recorded radio dramas such as "The Flying Swallow in Wan Li" and "The Blue Tapestry" were recorded and distributed in various radio stations. 


  After 1955, radio drama was on the rise, and a number of influential plays appeared successively. The more distinctive features are: the radio drama "Riverside at Dawn" recorded by recording the scene on the spot sounds more hierarchical and more real; There is also The Emperor’s New Clothes, which is adapted from Andersen’s fairy tales. The drama uses indoor and outdoor recording techniques, which has a strong three-dimensional sense and high artistic quality. It has a great response after being broadcast on CCTV’s News Network. This is the first time that a radio drama has met the audience on CCTV’s News Network. 


  From 1960 to 1963, there appeared some radio dramas with strong thoughts and high artistry, such as Hometown, which opposed the discrimination of African-Americans, and the radio dramas Unfinished Tung Skirt, In the Riptide, Du Shiniang, Hongyan, Two Paintings, etc. The radio drama Hongxia in the Valley was also sent abroad to participate in competitions. 


  On October 1, 1978, China Central Radio produced and broadcast the first original radio drama "Two Springs Reflecting the Moon" after the Cultural Revolution. After the broadcast, the reaction was very strong, and Bayi Film Studio adapted it into a film of the same name. After the Cultural Revolution, the creation of radio dramas, which was interrupted for 10 years, began to show a vibrant and prosperous scene, and a large number of outstanding plays such as Window, Scar, Dead Light on Coral Island, Necklace, and Marshal Peng’s Hometown Trip appeared one after another. The radio dramas Nangong Lingxia created by CCTV, When Clouds Are Cloudy and Why Melons Are So Sweet by Hunan Radio, and Princess Ringing by Jilin Radio were widely praised by the audience. In particular, the radio drama "Li Zicheng Rushing to Shimen Village" adapted from some chapters of Yao Xueyin’s novel "Li Zicheng" was introduced abroad as a cultural exchange project, which is the first time that China’s radio drama has spread to foreign audiences. 


  In 1980, Beijing Broadcasting Institute began to teach the course of "Literary Editing", in which part of the content was the theory of scriptwriting of radio dramas, and then it was decided to set up a special radio drama class, and radio drama teaching began to enter the university campus. As a professional media college, Beijing Broadcasting Institute has also begun to study the history of radio drama. 


  On November 15, 1980, the first national radio drama exchange meeting was held in Chengdu, and the meeting passed the establishment of the China Radio Drama Research Association. 93 representatives from 41 units, including the central, provincial, municipal and autonomous regional people’s broadcasting stations, some provincial and municipal people’s broadcasting stations and Beijing Broadcasting Institute (predecessor of China Communication University), attended the meeting. At the meeting, people in the industry discussed the newly produced radio dramas provided by the ceded territory radio station, and decided that China Drama Publishing House would publish the first Selected Radio Plays in China, collecting outstanding plays broadcast on radio stations since the founding of the People’s Republic of China and new works in recent years. Cao Yu, chairman of the Dramatists Association and a famous dramatist, wrote a preface about the artistic characteristics of the Selected Radio Plays. After the establishment of the research association, a series of fruitful national exchanges and awards activities have been carried out. Radio drama has been paid more and more attention by local radio leaders and supported by Chinese Dramatists Association, and a good situation of creative prosperity has emerged. 


  On New Year’s Day in 1981, Guangdong Radio broadcasted the first stereo radio drama "The Story of Fisherman and Golden Fish" adapted from Pushkin’s fairy tale poems. After that, Heilongjiang Radio, Shanghai Radio, China Central Radio, Sichuan Radio and Wuhan Radio also recorded stereo radio dramas, which made the radio dramas enter a new stage. 


  In December, 1981, the radio drama exchange meeting held a preliminary evaluation meeting of national excellent radio dramas in Changsha. At the meeting, 51 radio dramas recommended by 49 radio stations were listened to intensively, and 30 outstanding plays were selected after the comments of the representatives of each station. 


  In 1981, more than 370 radio dramas were produced nationwide. 


  In 1982, more than 600 radio dramas were produced nationwide. 


  In 1983, more than 500 radio dramas were produced nationwide. 


  In April 1983, a special award for children’s radio dramas was set up, and a national children’s radio drama selection conference was held in Beijing. From 83 radio dramas, 22 works were selected, including The Story of Mushroom, A Letter to be Sent, Fat, Little Guy, Big Guy and Tall Girl, Bailey Football Team and Weird Shoemaker. 


  In July 1983, a national conference on radio drama music was held in Xiamen. At the meeting, representatives of China Central Radio, Shanghai Radio, Heilongjiang Radio, Jilin Radio, Tianjin Radio and Fujian Radio made special speeches on the status and role of music in radio dramas, the collection, classification, sorting, storage and application of music materials. 


  In 1984, China Radio Drama Research Association decided to hold large-scale radio drama awards nationwide, and successively held the "Dangui Cup" radio drama grand prix, the national children’s radio drama "Golden Monkey Award", the national audio sketch awards, the "Xifeng Cup" national series exhibition and awards, and the "Magnolia Cup" mini radio drama grand prix. 


  In 1986, CCTV broadcast a series of radio report drama "Ordinary People", which has three outstanding characteristics: first, it absorbs bad news reporting structure; Second, there is no clear space environment; The third is to unify the task of recording and shaping. It is a bold attempt in the history of China radio drama. 


  In June 1987, China Central Radio and Heilongjiang Radio participated in the 10th "West Berlin Future Award" radio program grand prix, and the stereo radio drama "Subtract Ten Years" based on Zhan Rong’s novel of the same name (directed by Wang Zhifu) selected by China Central Radio won the radio drama grand prize. This is the first time that China has won the highest award in the world awards. It marks that the artistic level of China’s radio drama has entered the advanced ranks of the world level. The judges’ comments on Subtracting Ten Years Old are: "This is a wonderful and lovely satire with novel ideas and originality" and "It makes us see the changes of people in China and China after the opening up". 


  In 1988, the first national seminar on the creation of radio dramas was held. 


  In 1990, China Radio Drama officially entered the scope of national awards, and the Ministry of Radio, Film and Television entrusted the China Radio and Television Society to host the awards. So far, awards have been held successively, such as Shu Xiu Cup, Shi Song Cup and Black Dragon Cup, and a number of awards have appeared, such as Red Olive by CCTV, Blacksmith, Shoemaker Feng and Their Women by Heilongjiang Radio, Beyond Life by Shanghai Radio, Old Bachelor and Pretty Widow by Henan Radio and Difficult Worries on Earth by Harbin Radio. 


  On March 2-9, 1990, the China Radio Drama Research Association held the first national symposium on the theory of stereo radio drama in Wuxi. The conference set up questions about the script creation, directing art and production experience of stereo radio drama brought about by the new technology of stereo compromise. 


  On August 10th, 1990, Shanghai People’s Broadcasting Station launched a large-scale series of radio drama "Interpol 803", which created a new situation in Shanghai’s radio drama. The drama quickly formed a listening craze in Shanghai, and it is no exaggeration to describe it as a "household name". The radio drama "Interpol 803" was broadcast in a large scale and lasted for a long time, which was the highest in China. Many radio stations in the country played it one after another, which set off an enduring listening fever. 


  On October 5-14, 1993, at the 30th AFC Conference held in Auckland, New Zealand, the children’s radio drama Tomb in Danger produced by China Central Radio won the AFC Broadcasting Children’s Program Award, which was the first time that China participated in the AFC competition. The high-level radio drama production technology shown in the play was highly appreciated by the judges. 


  In 1993, China also produced a number of large-scale radio series adapted from classical literature, such as 108 episodes of Romance of the Three Kingdoms produced by Sichuan Radio, Dream of Red Mansions produced by China Central Radio and 67 episodes of Water Margin produced by Heilongjiang Radio. 


  On February 6th, 1996, Publicity Department of the Communist Party of China issued Document No.1, which included radio drama in the "Five-One Project" of spiritual civilization construction, which greatly promoted the social status and influence of radio drama and the construction of socialist spiritual civilization, and also caused the party and government departments in various provinces and cities to attach great importance to and strongly support radio drama, a unique artistic variety of literary broadcasting. 


  2005 was a bumper year in the history of China’s radio dramas. According to the statistics of China Radio Drama Research Association, this year, about 2,180 radio dramas (including news reports from all over the country) were produced nationwide, and the production situation showed that the central, provincial, municipal and county media went hand in hand, thus reaching a new peak in history. 


  On September 13th, 2006, the general offices of the General Office of the Central Committee of the CPC and the State Council issued the Outline of National Cultural Development Plan during the Eleventh Five-Year Plan, which clearly pointed out that it was necessary to "implement cultural quality projects" and "launch a number of films, TV dramas and radio dramas with important influence", and once again included radio dramas in the "Five One Projects" of spiritual civilization (radio dramas were cancelled from participating in the "Five One Projects" in early 2005). The "Outline" established the "name" for the radio drama and improved the "identity". 


  At the beginning of 2008, the leaders of the State Administration of Radio, Film and Television made the instruction that "radio dramas should learn from TV dramas and take the road of market", which put forward requirements for radio dramas to March into the market. 


  On October 5th, 2009, the 46th General Assembly of the Asia-Pacific Broadcasting Union was held in Ulaanbaatar, the capital of Mongolia. The radio drama Heart Destiny selected by china national radio won the best radio drama award of the Asia-Pacific Broadcasting Union. 


  After entering the 21st century, the emergence of the Internet, the prosperity of the media market, and the addition of mass entertainment elements have given radio dramas more room for development. 


 


Link: Cao Yu’s witty remarks


  The famous playwright Cao Yu said affectionately when talking about radio dramas: 


  "The life of radio drama lies in its unique personality. The artists of radio dramas left the audience with a vast world, which enabled the audience to participate in the creation. The audience is the creator of the radio drama. Close your eyes and listen, all the characters, the endless changes of life, with magical language and sound, you don’t feel like spreading the wings of imagination and soaring in the mysterious world. " 


  "I like to enjoy this art alone in a quiet night. It does have a special charm, which can touch people’s emotional depths, make people fly, and make our world turn into a myriad of vivid faces with closed eyes and listening. " 


  Radio drama is a goddess of charm, like poetry and dreams, which makes people enjoy all the wonderful things in the sound world.

Novel nanoparticles can deliver anticancer drugs into cells.

Researchers have designed a novel graft polymer shell for iron oxide nanoparticles, which can deliver anticancer drugs and realize real-time monitoring of drug release.

  Recently, chemists at the University of New South Wales (UNSW) in Australia have synthesized a new type of iron oxide nanoparticles, which can not only deliver anticancer drugs to cells, but also monitor the release of drugs in real time. Researchers say this is an important progress in the field of nano-diagnosis and treatment. Related papers were published in ACS Nano, a journal of American Chemical Society recently.

  "This kind of iron oxide nanoparticles can track and monitor drug delivery, which makes it possible to adapt to the individual differences of different patients." Cyril Boya, an associate professor at UNSW School of Chemical Engineering, said. Knowing how the anticancer drug delivered by nanoparticles is released and its influence on cells and surrounding tissues, doctors can adjust the dosage to achieve the best curative effect of the drug.

  For a long time, magnetic iron oxide nanoparticles (IONPs) have been widely studied, but most of them are used as contrast agents in magnetic resonance imaging (MRI). Only recently have they been explored for drug delivery. At present, only a few studies have described how to load chemotherapy drugs on the surface of magnetic iron oxide nanoparticles, which can not effectively prove that they can really deliver drugs into cells, just some speculations. In this study, a new method was designed to load drugs on the surface of IONPs, and it was proved for the first time that these particles could deliver drugs into cells.

  UNSW researchers fitted IONPs with a well-designed graft polymer shell, which made it show excellent colloidal stability in water and serum. Polymer shell can realize the reversible adhesion of doxorubicin (an anti-tumor drug) through imine bond, which provides a controllable release mechanism for doxorubicin in acidic environment.

  Using a technique called Fluorescence Lifetime Imaging Microscopy (FLIM), researchers proved for the first time that IONPs can be easily accepted by two cell lines (MCF-7 breast cancer cells and H1299 lung cancer cells), and at the same time, the release of DOX in cells can be monitored.

  "Usually, drug release experiments are only simulated in the laboratory, not in cells. This is very important. With cells, we can determine the dynamic movement of drug release in a real biological environment. " Boya said, "We have proved that workbench chemistry (referring to traditional chemical experiments without high-end equipment and computer models) can also be carried out in cells, and the next step is to enter the living application."

It is not terrible to treat heart failure in time.

The heart is one of the most important organs for us, and its existence and health affect our body and life.
There may be many problems in the heart, among which heart failure often makes people talk about it. Heart failure is the abbreviation of heart failure, which refers to serious cardiac insufficiency, that is, the systolic and/or diastolic function of the heart is impaired. It is not a disease, but an abnormal state that affects the whole body, which is caused by the gradual progress and aggravation of other primary heart diseases, resulting in the loss of compensatory ability of cardiac function, which leads to the inability of the heart to bear the normal physiological blood pumping demand. Heart failure is a state, belonging to a kind of organ failure, which is formed based on the gradual aggravation of some heart diseases themselves, and is often the end-stage manifestation of heart disease. Can be acute onset, chronic development, but also divided into left heart failure, right heart failure and heart failure.

There are many causes of heart failure. Infection: viral myocarditis, infective endocarditis, etc. Myocardial ischemia or pathological changes: severe coronary heart disease, dilated cardiomyopathy, etc. The structure of the heart is abnormal: complex congenital heart disease, long-term heart valve disease and so on. Almost all cardiovascular diseases, even improper drugs and excessive mood fluctuations may lead to heart failure.

Heart failure will have different manifestations according to the priority: acute heart failure is dangerous, with typical sitting breathing and obvious symptoms; Chronic heart failure often has no characteristic manifestations at first, and it is often labor-induced dyspnea at first. When it is seen in mild physical labor, it has obvious dyspnea and palpitation discomfort, and then it will suddenly wake up and have difficulty breathing during quiet sleep at night. Left heart failure is characterized by decreased activity ability and even inability to complete daily self-care; Right heart failure often has depressed edema of the lower limbs, mostly located in the ankle. After pressing with fingers, the swollen skin will not rebound immediately, and a small depression will appear. This is because of poor blood return caused by cardiac insufficiency.

Heart failure is the process of heart disease progression and the manifestation of the end stage of the heart. Whether it is terrible depends on the primary disease and the degree of progress. Acute heart failure, like viral myocarditis, is often very dangerous, and it will be life-threatening if it is not treated in time. As long as chronic heart failure is treated as early as possible, those patients with mild or moderate heart failure can still get a better prognosis. As for the popular saying that "patients with heart failure can only live for five years, which is more terrible than cancer", there is no such saying. Early detection, early intervention and treatment of heart failure can still achieve a better prognosis. With the development of medicine, many measures to treat end-stage heart failure, such as heart transplantation, artificial heart and ventricular assist, are being applied in clinic, which will greatly improve the long-term survival rate of patients with heart failure.

So, how to reduce the risk of heart failure? Except for a few diseases that cannot be treated at present, such as dilated cardiomyopathy, in most cases, as long as they are treated in time, they will not develop into heart failure. Therefore, active treatment of primary heart disease is the primary means to improve the prognosis of patients. Patients with heart failure need to treat primary heart disease first. At this time, patients often have a serious primary disease, so standardized treatment is more needed. In addition, we should pay attention to the following aspects: avoiding colds and preventing infections; Pay attention to diet, water and sodium retention in patients with heart failure can alleviate the above symptoms by reducing sodium intake; Control the amount of drinking water and monitor the inflow and outflow. If the long-term inflow is greater than the outflow, the heart burden will be heavier and heart failure will be aggravated. Pay attention to rest and avoid overwork; Patients with heart failure can be properly treated with diuresis, but diuresis also needs to monitor electrolytes and maintain electrolyte balance, especially potassium ions; Regular follow-up, do not adjust drugs without authorization; If you have obvious symptoms such as chest tightness, breath holding, and inability to lie flat, see a doctor in time.

Global anti-epidemic Guangzhou shares anti-epidemic wisdom with the world

  A rare COVID-19 epidemic is raging around the world. The epidemic is the common enemy of all mankind, and unity and cooperation are the most powerful weapons and the only correct choice for the international community to overcome the epidemic. Anti-epidemic materials rushed to the international friendship city, doctors and experts went overseas to support, and cross-border connections shared anti-epidemic experience. Greater Bay Area’s strength in the global fight against epidemic, Guangzhou is in action.

  01Epidemic prevention materials rushed to the international friendship city

  Help each other in the same boat. Since the global outbreak of COVID-19, Guangzhou has actively organized epidemic prevention materials to help dozens of cities in more than a dozen countries.

  Liu Baochun, director of the Foreign Affairs Office of the Guangzhou Municipal Government, said: "When there were epidemics in other countries in the world, we immediately extended a helping hand. We have issued three batches of materials, covering almost 40 cities, and some belong to corresponding international organizations. "

  02Share Guangzhou’s anti-epidemic experience with the world

  Guangzhou has been invited to attend online seminars on international epidemic prevention and control experience held by UN-Habitat, World Cities and Cities Organization, world association of major metropolises, C40 Urban Climate Leadership Alliance and World Cities and Cities Organization Asia Pacific for many times, and introduced Guangzhou’s epidemic prevention experience in detail in four seminars, vividly telling the epidemic prevention story in Guangzhou and accurately responding to foreign concerns and needs.

  Tang Xiaoping, director of the Guangzhou Municipal Health and Wellness Committee, has participated in two sharing sessions: "I want to contribute our Chinese plan, or Guangzhou plan and Guangzhou wisdom through such video exchange. I think it is also very meaningful."

  03 doctors and experts go overseas to support

  A Chinese medical expert group sent by the Red Cross Society of China arrived in Baghdad International Airport from Guangzhou on the evening of March 7 to assist in the prevention and control of COVID-19 epidemic in Iraq. The expert group consists of seven experts, two of whom are outstanding backbones selected by the First Affiliated Hospital of Guangzhou Medical University.

  Huang Kunjin, president of the First Affiliated Hospital of Guangzhou Medical University, said: "In addition to the test of epidemic situation, Iraq is also facing the test of personal safety. The two doctors showed great composure and confidence in their work. They helped the local people and the local government by introducing China’s prevention and control experience. "

  04"Made in Guangzhou" helps the global fight against epidemic.

  "Made in Guangzhou" epidemic prevention materials and testing reagents actively help the international anti-epidemic. Among them, Guangzhou Wanfu Biotechnology Co., Ltd. and Daan Gene Co., Ltd. donated or provided more than 100,000 test kits to Kyrgyzstan and Iraq.

  The Red Cross Society of China donated a set of nucleic acid detection laboratory equipment to Iraq, which was provided by Sun Yat-sen University Daan Gene Co., Ltd.. Chairman He Yunshao said: "Not only reagents for 50,000 people have been prepared, but also nucleic acid detection instruments, extraction instruments and a complete set of laboratory equipment. There are more than 100 boxes, weighing about 3 tons."

  Wanfu Bio is one of the first batch of diagnostic reagent manufacturers with "zero defect" approved by FDA in the United States. The three novel coronavirus detection products independently developed by Wanfu Bio have obtained CE certification issued by the European Union, which can meet the needs of rapid detection and prevention of epidemic situation in various countries.

  Kang Keren, senior vice president of Guangzhou Wanfu Biotechnology Co., Ltd. said: "As of April 19, our products with more than 18 million people have been urgently sent to more than 70 countries and regions around the world. We are doing our best to help the country and the world fight the epidemic together. "

  In Huangpu District, Guangzhou, where Wanfu Bio and Daan Gene are located, the Customs took the initiative to open a green channel to "accelerate" the export of foreign aid materials.

  Li Hong, head of the Biosafety Supervision Section of the Health and Quarantine Department of Huangpu Customs, said: "At present, 68 batches of foreign aid reagents and 3.7 million people have been approved at an accelerated pace, with zero distance, full process and online approval, and the approval time has been shortened to one working day. From March to now, our approval volume has tripled. "

  The epidemic is still spreading around the world, and global efforts to fight the epidemic continue.

  As Academician Zhong Nanshan said, all people should unite as one world and fight against the epidemic together. For the sake of the community of human destiny, "epidemic" is obligatory!

  Welcome to continue to pay attention

  The Voice of Greater Bay Area, together with the media in various cities in the Bay Area, planned and produced a series of media-integrated programs, each focusing on one city and telling the story of Greater Bay Area’s participation in international anti-epidemic cooperation.

Cost-effective/Large Space Comments on Three Seven-seat SUVs within 80,000.

    [XCAR New Car Review Original]

    With the full liberalization of the national second child policy, many families choose to give birth to a second baby, but after the baby is born, problems also follow. It seems that the original five-seat SUV at home is not enough, but there is no room for economic conditions to choose seven-seat commercial vehicles, so many people have begun to seek a seven-seat SUV model with high cost performance. At this time, the advantage of the 7-seat SUV within 80,000 yuan is very obvious. In today’s article, let’s take a look at three China-branded 7-seat SUVs with a cost performance ratio of less than 80,000 yuan. They are Zotye Damai X5 Seven-seat Edition, Kerry K50S and Beiqi Magic Speed S3.

    In terms of interior and configuration, the biggest difference between the seven-seat version and the five-seat version is the addition of a third row of seats. As can be seen from the figure, due to the size limitation of the Damai X5 body, the space of the third row seat of the car will not be very large. However, the second row of seats is equipped with sliding rails, so it will be very convenient for the third row of passengers to get on and off.
