　　As soon as the AI pathologist came out, he refreshed the highest level of AI-assisted cervical cancer screening at home and abroad that has been published internationally!

　　On the basis that the negative rate is higher than 60%, the correct rate of negative interpretation of cervical smear is higher than 99%, and the detection rate of positive lesions is over 99.9%. Cytopathologists read cervical smear under microscope, which takes an average of 6 minutes per case, while AI identification takes only 36 seconds. The interpretation speed of AI-assisted cervical cancer screening model is 10 times that of manual interpretation!

　　The all-media reporter of Guangzhou Daily learned from the release conference of artificial intelligence-assisted cervical cancer screening in China Bio-industry Conference that Jinyu Medicine and Huawei technology have made a breakthrough together. Based on pathomorphology, the teams of both sides trained an accurate and efficient AI-assisted cervical cancer screening model with the diagnostic criteria of pathologists for the first time through deep learning technology.

　　Pathology is the gold standard of diagnosis, but there are too few pathologists.

　　Pathomorphological diagnosis is recognized by the medical community as the "gold standard" for disease diagnosis.

　　Dr. Liang Xiaoman, a well-known cytologist in China, has been engaged in clinical cytological diagnosis in the Cancer Hospital of Sun Yat-sen University of Medical Sciences for decades. He pointed out that the body has pathological changes. What exactly does it mean? Benign or malignant? What is the degree? Diagnosis depends on different morphological changes of pathology.

　　However, only 5,000 cells are qualified for a pathological glass slide, and there are tens of thousands of cells. If pathologists look at it one by one, it will be exhausting and very boring to look at 100 pieces a day. Therefore, a "pathological person" sees 90% negative films every day, and gets excited when he sees positive films. "It’s really not easy to see people get excited when they are sick," said Liang Xiaoman. This is a double high effort of brain power and physical strength.

　　There is a great demand for pathological diagnosis, but there is a shortage of pathologists.

　　Liang Xiaoman said, for example, like cervical cancer screening, cytology should be combined with HPV testing. In China, there are more than 350 million school-age women aged 25-65, and screening once every 3-5 years requires 70 million people to be screened every year. But in fact, since 2009, women’s screening for two cancers has been promoted, and the total number of cervical cancer screening in 10 years is only a little over 70 million, that is, the population coverage rate is only 21.4%.

　　Medical research shows that the population coverage rate of screening should reach 80% in order to reduce the incidence of diseases in the population.

　　The lack of disease screening ability lies in the long-term scarcity of pathologists in China. Reading films under traditional microscope needs to be based on human visual interpretation, knowledge accumulation, skills and talents, and the training period can often be as long as 10 years. The data shows that there are currently less than 20,000 registered pathologists in China, and the gap is still as high as 80,000-100,000 based on the standard of 1-2 pathologists per 100 beds.

　　AI-assisted cervical cancer screening made a major breakthrough

　　"So, I am very excited to hear that AI pathologists have made a breakthrough in research and development!" Liang Xiaoman said that it was initially seen that "this AI pathologist" can reduce the workload of manual interpretation by about half, which means that the other half of labor and energy can be devoted to improving the positive rate interpretation, and the chances of pathologists being complained of "seeing less, not seeing correctly and seeing slowly" will also be greatly reduced.

　　The AI pathologist mentioned by Liang Xiaoman refers to the AI-assisted cervical cancer screening model jointly developed by Jinyu Medical and Huawei Cloud.

　　There are about 500,000 new cases of cervical cancer in the world every year, and the incidence rate in China accounts for 26%. As long as the disease of cervical cancer is screened and treated early, its cure rate and five-year survival rate can be greatly improved.

　　According to reports, this development is based on 43.5 million cervical cytology screening samples over the years, and nearly 200,000 image blocks are selected for accurate labeling and AI-assisted screening model training.

　　First of all, it is marked by many pathologists to ensure that the model can fully learn the morphology of various pathological cells. Based on the block-level labeling of these images, the AI model first classifies the samples and efficiently distinguishes the samples with high positive cell density.

　　Then, the AI model further accurately identifies positive cells to ensure that accurate auxiliary interpretation results can still be obtained on samples with low positive cell density. In order to ensure the correct results, the algorithm also selects a series of suspicious local visual fields and submits them to the pathologist for final review.

　　At present, the AI model has been verified with the verification set of more than 20,000 sample data. The verification results show that the negative rate of the model is 61.9%, the accuracy of negative film interpretation is higher than 99%, and the detection rate of positive lesions is over 99.9%. This is the highest level of AI-assisted cervical cancer screening at home and abroad.

　　Application of results:

　　There are at least three to five years before landing.

　　The development of AI pathologists can be described as an important practice of digital medicine and precision medicine, which provides strong support for accurate diagnosis in the future. Once the results are applied, it is expected that the workload of single cytological examination by pathologists will be reduced by more than 60%, and the screening efficiency will be greatly improved. Usually, it takes 6 minutes for cytopathologists to read cervical smear under microscope. The AI ? ? recognition takes only 36 seconds, and the interpretation speed is 10 times that of manual interpretation.

　　At the same time, by comparing and verifying the results of AI tips, doctors can make manual interpretation more conveniently and accurately, which can bring effective help to the quality control of pathological examination and the training of pathological students.

　　In terms of greater social benefits, in the future, once AI-assisted cervical cancer screening is applied and promoted, it will greatly improve the coverage and service frequency of cervical cancer screening services, so that the screening quality of school-age women can approach the level of developed countries and promote early screening and early treatment of cervical cancer.

　　However, experts also admit that the results are at least three to five years away from landing.

　　First of all, we should continue to invest more sample data to verify the AI model on a large scale, and at the same time make more professional annotations to improve the model, so that its specificity will be continuously improved under the premise of ensuring sensitivity, and even adapt to and be close to the reagent consumables and production level of primary hospitals.

　　Secondly, it is ready to start the registration of CFDA. It is understood that there is no clear guiding process and cycle at present. "Many analysts in the industry believe that the large-scale application of medical AI such as pathological AI and imaging AI in China is estimated to take 3 to 5 years."

　　"AI pathology" vs "AI image" is more accurate.

　　In recent years, AI medical care has become more and more hot, which belongs to the field of auxiliary diagnosis. AI images have developed even faster and entered the registration application process earlier than AI pathology. So, which is stronger, AI pathology or AI image?

　　In this regard, some cytopathologists believe that AI pathology is "more difficult, more refined, more lacking and slower".

　　Because the image is based on black and white, density, size and edge, and the pathology is polychromatic and reaches the cellular level, it is not just an auxiliary diagnosis of "whether it is a tumor" or "whether it is a lesion".

　　In other words, AI imaging doctors can "allow" the conclusion that "this may be a cancer, a benign tumor or a malignant tumor", while AI pathologists can’t do this, but tell "what is this, is it a cancer, and what kind of cancer it is".

　　On Teacher’s Day in 2019, in the smart classroom of Friendship Campus of Northwestern Polytechnical University, students were sitting around a big screen. At the other end of the screen, Fang Shuting, an interpreter of Chen Wangdao’s former residence in Yiwu, was lovingly telling the students the story of Mr. Chen Wangdao’s translation of the communist party Declaration. The students listened attentively and were deeply moved by Chen Wangdao and the older generation of proletarian revolutionaries’ persistent pursuit of truth. This was a scene in which the school launched the "5G Ideological and Political Course".

　　Northwestern Polytechnical University also initiated the "5G+ Education for Poverty Alleviation" in China. Students from the folk band, symphony orchestra and chorus of college students’ art troupe showed and explained all kinds of musical instruments and sang the song My People，My Country for the children in Wang Xiaoxue, Weinan City, Shaanxi Province, to celebrate the 70th birthday of New China.

　　This is just a microcosm of educational informatization in Shaanxi Province. Shaanxi Province is located in the northwest of China, with a large number of poverty-stricken counties and districts. The development of education in urban and rural areas is uneven, and problems such as large class size, school selection fever and shortage of teachers have been restricting the development of education. In recent years, around the three-stage development strategy of "improving environment, expanding application and deepening integration", Shaanxi Province has comprehensively deployed and promoted the construction of educational informatization and big data, explored and built a new ecology of "Internet+education", promoted the innovative development of information technology and education, and created a unique development path for promoting education equity and improving education quality.

　　"Full participation, inclusion in the assessment, one-vote veto, delayed accountability" assessment and notification evaluation mechanism

　　Elaborate the Top Project of "internet plus"

　　Shiquan County, Shaanxi Province is a poverty-stricken county in mountainous areas. At the end of 2017, it was awarded the "first batch of educational informatization pilot units" by the Ministry of Education, and it is the only regional comprehensive pilot unit among the six excellent pilot units selected by Shaanxi Province. When accepting the pilot acceptance of the Ministry of Education, Zhou Yaoyi, the county magistrate of Shiquan County, said, "Under the unified deployment of the Shaanxi Provincial Department of Education, we set up a leading group for education informatization, set up an informatization unit in the county education bureau, and clearly established three 10% funding input mechanisms. Education informatization has achieved remarkable results in promoting the balanced development of education in Shiquan County."

　　As early as 2013, Shaanxi carried out the standardization construction of educational informatization management system and mechanism, and issued evaluation standards. By the end of 2017, universities and education administrative departments of cities and counties in the province had established systematic and complete educational informatization administrative promotion institutions, forming a perfect management system and mechanism.

　　In order to improve the political position, the Shaanxi Provincial Department of Education has always been headed by the "number one" director. Especially this year, after the Education Working Committee of the Provincial Party Committee and the Provincial Department of Education were co-located, the members of the leading group were adjusted in time, with the secretary and the director as the team leaders at the same time. The Education Informatization Department was also adjusted and established, and the mechanism of "full participation, inclusion in assessment, one-vote veto and delayed accountability" was established.

　　Wang Jianli, director of the Education Department of Shaanxi Province, told reporters, "We should take informatization as the endogenous factor of educational reform, focus on solving major problems of educational reform and development, promote educational equity and improve the quality of education, and vigorously promote the development of educational informatization in the new era, providing strong support for the modernization of education in Shaanxi and the construction of a strong education province."

　　Equity of Sharing "Internet+Education" in Urban and Rural Areas

　　"The teacher on TV came to our school, so kind!" A student from a nine-year school in Yankou Town said. Not long ago, Chengbei Primary School in Xixiang County went to Yankou Town Nine-year School to carry out long-distance interactive classroom teaching activities, with Yankou Town Nine-year School as the main classroom and Chengbei Primary School and Chazhen Nine-year School as the receiving classrooms, and carried out exchange lectures and recipient classroom experience activities, with online and offline dual synchronous teaching of Chinese and fine arts, which enriched the contents and ways of long-distance interactive teaching.

　　"In the past, teachers who could read microscopes in the nine-year school in Yankou Town could not be found. Now, remote interactive teaching can solve this problem. Driving teachers to learn and teaching, our goal was achieved through experiments. " Li Qingfeng, deputy director of the Education and Sports Bureau of Xixiang County, told the reporter that at present, there are 45 long-distance interactive classrooms in Xixiang County, namely, Xixiang No.3 Middle School, Lianhua Primary School and Dahe Town Nine-year School, Xixiang No.5 Middle School, Dongguan Primary School and Gao Chuan Town Primary School, which are 75 kilometers away, and Lianghekou Town Primary and Secondary School, which are 90 kilometers away, have crossed the time and space distance and entered a brand-new learning environment together with the last class. One school has many schools and one school has many points.

　　Not only in Xixiang, in Ningqiang, but also in rural primary schools in the vast northwest, there is a micro-lesson, a test paper, a bowl of preserved eggs and lean porridge, a football, a song and a familiar face … … These stories all reflect the profound changes of educational informatization to rural schools. Since vigorously implementing the construction of "three links and two platforms", Shaanxi’s education system has made up shortcomings, promoted upgrading, and accelerated the construction of school information infrastructure. At present, it has achieved full coverage of broadband networks in all levels and types of schools in the province, and the proportion of multimedia teaching equipment in ordinary classrooms has exceeded 90%, and the gap between urban and rural environments has been narrowing.

　　How to further realize Urban-rural Education Fairness, so that every child can enjoy high-quality educational resources? By promoting the large-scale application of the platform for everyone in secondary vocational schools and primary and secondary schools, Shaanxi Province has realized the accurate push of high-quality digital education resources. The platform has been deployed in 8 cities and 75 counties (districts), achieving "one point access and sharing in the whole province", with nearly 400,000 registered teachers in primary and secondary schools and secondary vocational schools. The platform continuously integrates micro-lesson contest and other activity resources. At present, the total amount of high-quality educational resources is more than 8 million, covering all disciplines and study sections. The high-quality resources are continuously covered in rural areas, remote and poor areas, and the ability of teachers to integrate and apply has been greatly improved, realizing "sharing high-quality educational resources under the same blue sky".

　　From the past "people looking for policies" to the present "policies looking for people"

　　"Internet+Government Affairs Service" to Improve Education Governance Ability

　　The repeated attacks on campus are shocking, and the security incidents are thought-provoking. In the current digital era of open information, how can we use big data to build an "iron wall" for children, maintain campus security through information technology, and improve the ability of education governance? In the Big Data Application Service Center of Shaanxi Provincial Department of Education, you can see a series of big data construction achievements and educational governance methods. Campus security managers can access the surveillance videos of universities and primary and secondary schools in the province anytime and anywhere, even accurate to every corridor, every canteen operation room and every playground. Security incidents can be commanded in time and accurately, and emergency measures can be launched immediately in case of danger.

　　Liu Baoping, chief accountant of Shaanxi Provincial Department of Education, said, "The education system of the whole province is in accordance with the provincial party committee and the provincial government ‘ One Netcom Office ’ And ‘ Internet+government services ’ Relevant requirements, vigorously promote the construction and application of education big data, and strive to solve social hot and difficult problems such as large class size and school choice fever, which are strongly reflected by the masses. " In March 2018, Liu Baoping introduced at the press conference on student financial aid of the Ministry of Education that Shaanxi’s "precise funding" and "controlling dropping out of school" based on big data covered all students from families who set up files and set up cards, and dynamic monitoring, real-time early warning and day-to-day processing have been realized, which has improved the "accuracy" of education funding, effectively made information run more and students run less errands, and realized "changing management into service". In addition, Shaanxi Province has creatively built an "educational map big data analysis platform" to visually display the information of the province’s educational development, educational planning and the tracking of educational hot issues in the form of maps. The planning and distribution of primary and secondary schools are more closely combined with the population dynamic trend, and the layout is more reasonable.

　　The reporter also learned that Shaanxi education big data construction has gone through the stages of management information system construction, provincial data aggregation platform construction, education basic data aggregation, data governance and mining application, and realized the integration, aggregation and sharing application of core management data, and entered the era of education big data 2.0, initially forming a sharing system of education big data construction at the provincial, city/university, district/county levels, sorting out 429 business items and drawing 458 business flow charts. It has gathered more than 20,000 data of educational institutions and nearly 9 million data of teachers and students in the province, solved many hot and difficult problems through big data analysis, and formed a unique "Shaanxi model", which was affirmed by the leaders of the Ministry of Education, the provincial party committee and the provincial government, and its experience attracted colleagues from all over the country to study.

　　Build a stage for maker, innovation and creation.

　　"internet plus" gives new vitality to education in generate.

　　Shaanxi Yangling is known as the "modern agricultural city". Relying on the advantages of science and education, all primary and secondary schools in Yangling actively promote wisdom education, closely combine school education with agricultural science and technology and ecological culture, develop school-based teaching materials and digital resources of animals and plants with regional characteristics, and stimulate students’ innovative enthusiasm for exploring nature. "We actively try to enrich the educational form by using the information system composed of the core system of wisdom education, feedback device, tablet computer and physical reminder machine, organize the primary and secondary schools to carry out plant identification competitions, and solve the shortcomings of insufficient intuition in previous animal and plant teaching through novel forms, which stimulates students’ interest in learning." Zhang Shaowen, director of the Education Bureau of Yangling Demonstration Zone, said.

　　Giving birth to innovation is a natural advantage and a deep mission of educational informatization. Shaanxi Province actively promotes new modes of educational informatization, such as artificial intelligence, maker education, STEAM education and smart campus, and leads all-round innovation in education and teaching from different levels of regions, schools, teachers and students. Shaanxi has held the information-based teaching innovation competition for primary and secondary schools and secondary vocational schools in the province for four consecutive years, with 150,000 teachers and nearly 10,000 excellent micro-courses and innovative resources. Xi ‘an High-tech No.1 Primary School started writing early under the network environment, which opened a new model of primary school students’ writing. Xi ‘an Daminggong Primary School develops the characteristic school-based curriculum "Serialized Micro-class" and carries out flip classroom teaching based on micro-class. Shaanxi has also built a "Youth Maker Love Challenge Platform", held a youth "Love Challenge" carnival and a youth Maker Creative Competition, and participated in 300,000 students. A batch of school maker spaces has rapidly emerged, which has become a new growth point and breakthrough point of school informationization.

　　Maker, innovation and creation, with the attention and promotion of education departments at all levels in Shaanxi Province, have become a beautiful landscape of Shaanxi education. (Reporter Huang Wei)

　　　 Movie network news(Video/He Pantu/Yang Nan/Li Chao) A Chinese OdysseyStephen Chow made the Monkey King a classic in the hearts of countless people. After many years, Stephen Chow once again challenged the traditional story of The Journey to the West, only this time, Master Xing retired behind the scenes and became a director, while the person who played the Monkey King became Bo Huang. Recently, Bo Huang accepted an exclusive interview with [Movie Network]. He said that in order not to be compared with his previous work, he deliberately turned the Monkey King into an old man. The Monkey King is not beautiful, will the audience still buy it? Let’s see what Bo Huang, whom Stephen Chow called the comedy Wang Zhongwang, said.

Personally, I don’t have any style. It’s fun to cooperate with Xingye.

　　　 Stephen Chow and Bo Huang, two great comedians in the south and the north, will join forces with each other this time. What kind of chemical reaction can they have? Is it a perfect match, or is it the opposite? Bo Huang said that it is an actor’s duty to obey the director’s style; Working with Stephen Chow is a very happy thing in itself.

　　　 [Movie Network]: Do you think your comedy style matches that of Stephen Chow when you play the Monkey King in the film directed by Stephen Chow?

　　　 Bo Huang: This is the director’s problem. Personally, I don’t have any style. Actors are a part of film creation. It is also your job to serve the film better and integrate yourself into the overall temperament of the film. This visit is also an opportunity to learn. I used to like Stephen Chow’s works very much.

　　　 [Movie Network]: Do you think Stephen Chow’s style has changed?

　　　 Bo Huang: The director has his own creative characteristics, and he has a deep brand in the hearts of the audience. His previous comedy style and his comedy status have been well accepted by the audience. That’s what the audience likes. This is his personal characteristic, which is quite important. Let’s play more on the original basis this time.

"Journey to the West" stills

　　　 [Movie Network]: Was Stephen Chow serious when he directed the movie on the set?

　　　 Bo Huang: I don’t think so this time. Because making a comedy must be a very happy state to come up with those ideas. It’s still strange that you are unhappy here. Often, before chatting and shooting, I laughed and fell to the ground first.

　　　 [Movie Network]: For example?

　　　 [Movie Network]: A lot, he will make a lot of extreme demands. For example, you are already embarrassed and should be able to go, but he will think, if you don’t go at this time, what will be more embarrassing? He will be embarrassed to the extreme.
