| 1 | Epidemic Update and Risk Assessment of 2019 Novel Coronavirus--China, January 28, 2020显示文摘On December 29,2019,the health authorities in Hubei Province and Wuhan City received a report of a cluster of pneumonia cases of unknown etiology from a local hospital,and all four patients were employees of the Wuhan Huanan Seafood Wholesale Market(HN market for short)(1).By January 8,2020,Chinese authorities had identified a new virus 2019 novel coronavirus(2019-nCoV)linked with the outbreak of disease,which has been named novel coronavirusinfected pneumonia(NCIP)(2).On 15 January,the National Health Commission(NHC)issued guidelines for the diagnosis,treatment,prevention,and control of NCIP.These guidelines directed case monitoring,reporting,diagnosis,treatment,management,close contact management,and laboratory testing. | Wenxiao Tu Houlin Tang Fangfang Chen Yinong Wei Tingling Xu Kaiju Liao Nijian Xiang Guoqing Shi Qun Li Zijian Feng | 2020 | China CDC weekly2020，2，6： | 15 |
| 2 | Disproportionate Increase of New Diagnosis of HIV/AIDS Infection by Sex and Age--China, 2007−2018显示文摘What is already known about this topic?The annual rates of newly diagnosed HIV/AIDS among total population is increasing in China,yet HIV/AIDS in older adults has received little attention.What is added by this report?The overall rates of new diagnosis of HIV/AIDS per 100,000 populations increased 3.26 and 2.18 times among male and female in all ages from 2007 to 2018,respectively.Among adults aged≥60 years,the rate increased 10.41 times(1.35 to 14.06 per 100,000)from 2007 to 2018.Male adults aged 60–69 and 70–79 years and female aged 50–59 and 60–69 years had the highest increasing rates among all groups.What are the implications for public health practice?This study highlights the need to strengthen HIV/AIDS prevention among older adults.Health education and other effective measurements might be used to prevent HIV/AIDS among this group. | Yewu Zhang Chang Cai Xiaofeng Wang Yanfei Li Houlin Tang Jiaqi Ma | 2020 | China CDC weekly2020，2，5： | 5 |
| 3 | Epidemiological Characteristics of Newly Diagnosed Cases of HIV through Injection Drug Use-China, 2012–2019显示文摘Summary What is already known about this topic?The annual rates of newly diagnosed cases of human immunodeficiency virus(HIV)are increasing in China,yet the annual number of newly diagnosed cases of HIV infected through injection drug use(IDU)is decreasing. | Houlin Tang Chang Cai Yan Cui Qianqian Qin Fan Lyu | 2020 | China CDC weekly2020，2，48： | 2 |
| 4 | Analysis of Knowledge Level and Use of Antiretroviral Pre-Exposure and Post-Exposure Prophylaxis Among MSM—China,2019–2022显示文摘Summary What is already known on this topic?Men who have sex with men(MSM)in China have a high rate of human immunodeficiency virus(HIV)infection.Pre-exposure prophylaxis(PrEP)and postexposure prophylaxis(PEP)have been shown to be effective in preventing HIV,which may help to contain the HIV epidemic among MSM.What is added by this report?This study found that knowledge and usage of PrEP were low among MSM,indicating that this population is at high risk for HIV infection.Promotion of PrEP and PEP among MSM is necessary to reduce the risk of HIV infection in this population.What are the implications for public health practice?PrEP and PEP are novel HIV prevention strategies that have been demonstrated to be effective and safe.To further reduce HIV transmission among MSM in China,it is necessary to promote the use of PrEP and PEP. | Jiahuan Guo Wenting Kang Tongtong Liu Jie Xu Houlin Tang Fan Lyu Guang Zhang | 2023 | China CDC weekly2023，5，13： | 0 |
| 5 | Comparative Analysis of Epidemiological Features of HIV/AIDS Cases Aged Over and Under 50 Years Old—China,2010-2022显示文摘Introduction:Recent data indicate a year-on-year increase in the proportion of human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)cases reported among individuals aged≥50 in China.This study compares the epidemiological characteristics of HIV/AIDS cases in populations above and below 50 years of age.By doing so,it seeks to scrutinize the current epidemiological landscape of HIV within these distinct age cohorts and suggest tailored interventions for each group.Methods:We utilized data from the Chinese HIV/AIDS Comprehensive Response Information Management System for our comparative analysis.Joinpoint regression analysis was employed to assess the trends in standardized detection rates.Results:In China,the number of newly reported HIV/AIDS cases in the 15-49 age group increased from 51,436 in 2010 to 55,397 in 2022,while it increased from 11,751 in 2010 to 51,856 in 2022 in the group aged≥50 years.Recent years have seen a greater proportion and detection rate of HIV/AIDS cases among the≥50 age demographic compared to the 15-49 age group.In 2022,significant statistical differences were observed between males and females in both age cohorts with respect to education,marital status,occupation,mode of transmission,location of diagnosis,and region.Conclusions:The observed trend of a rising proportion of HIV/AIDS cases in individuals aged 50 years and older necessitates heightened attention.It is imperative that we develop and implement interventions specifically designed to prevent and control the transmission of HIV within this demographic. | Yushan Hou Yichen Jin Chang Cai Qianqian Qin Houlin Tang Fan Lyu | 2023 | China CDC weekly2023，5，48： | 0 |
| 6 | Countermeasure against blinding attack for single-photon detectors in quantum key distribution显示文摘Quantum key distribution(QKD),rooted in quantum mechanics,offers information-theoretic security.However,practi-cal systems open security threats due to imperfections,notably bright-light blinding attacks targeting single-photon detectors.Here,we propose a concise,robust defense strategy for protecting single-photon detectors in QKD systems against blinding attacks.Our strategy uses a dual approach:detecting the bias current of the avalanche photodiode(APD)to defend against con-tinuous-wave blinding attacks,and monitoring the avalanche amplitude to protect against pulsed blinding attacks.By integrat-ing these two branches,the proposed solution effectively identifies and mitigates a wide range of bright light injection attempts,significantly enhancing the resilience of QKD systems against various bright-light blinding attacks.This method forti-fies the safeguards of quantum communications and offers a crucial contribution to the field of quantum information security. | Lianjun Jiang Dongdong Li Yuqiang Fang Meisheng Zhao Ming Liu Zhilin Xie Yukang Zhao Yanlin Tang Wei Jiang Houlin Fang Rui Ma Lei Cheng Weifeng Yang Songtao Han Shibiao Tang | 2024 | Journal of Semiconductors2024，45，4： | 0 |
