子宫颈癌是全球女性常见的恶性肿瘤。2018年，WHO总干事向全球发出了消除子宫颈癌的动员令。我国的子宫颈癌人群防治工作累积了大量的实践经验，并取得一定成效。面对2030年“90%-70%-90%”的阶段性目标，我国仍有不同程度的挑战和机遇。人乳头状瘤病毒（HPV）疫苗在国内得以应用，部分省市已开展适龄人群接种，90%适龄女性接种疫苗的阶段性目标的实现较为乐观，应密切关注国际上HPV疫苗接种的研究进展；子宫颈癌人群筛查技术已取得突破性进展，但我国存在人口基数大、资源不足等困难，70%适龄女性接受高效检测方法筛查的目标存在较大困难，应尽早推广应用新技术，快速提高筛查服务能力及其均质化；我国子宫颈病变的治疗水平不断进步，且随着总体经济发展、基本医疗保险高覆盖、医保政策优化等，预计90%确诊子宫颈病变的妇女得到治疗的阶段性目标能够实现，目前应开展全国性治疗数据的收集。我国实现消除子宫颈癌的战略目标任重而道远。.

The Loess Plateau of China is the most concentrated and largest loess area on Earth. Shanxi Province lies in the eastern margin of the Loess Plateau and is one of the regions with the worst serious soil erosion and most fragile ecological environment in the world. On March 15, 2019, a landslide hit Xiangning County in Shanxi Province in northern China and resulted in heavy casualties. This paper mainly gives an introduction about the catastrophe, causes, and related emergency response.

A variety of dermatological lesions have been described in COVID-19, although the prevalence and pathogenic relationship remain unclear particularly for chilblain-like lesions. Dermatological examination was performed in a prospective cohort of consecutive patients seen at the service for SARS-CoV-2 infection. Out of 417 patients with confirmed SARS-CoV-2 infection [median age 29.5 years (range 15–65); 62.5% males], dermatological lesions were detected in 7 (1.7%). Three patients had acral lesions; their age (range) was 15–29 years; all had a negative nasopharyngeal swab and developed IgG and/or IgM-specific antibodies; all presented none or mild symptoms. A fourth patient remained negative at repeated testing; mother, father and sister had a documented mild COVID-19. Non-acral lesions were observed in four older patients, with severe COVID-19. Chilblain-like lesions may be the sole manifestation of SARS-CoV-2 infection; their presence in asymptomatic school children and adolescents should be considered a potential signal of familial or community spread of the virus.

Since March 2013, China had experienced five seasonal epidemics related to Avian influenza A (H7N9). An unprecedented outbreak of H7N9 epidemic started from September 2016, with 730 cases reported till June 30(th) 2017, in mainland China that caused profound influences on both social development and health of the people. As an emerging infectious disease, information on pathogenic characteristics, transmission patterns and other epidemiological features of H7N9 virus somehow remained unclear. Data from previous studies suggested that the live poultry market (LPM) seemed to have served as main places where H7N9 virus got originated, mutated, spread and thus infected the human beings. Hence, closure of LPMs was suggested a major measure to control and prevent H7N9 epidemics in China. However, the effectiveness of different ways of LPM closures on H7N9 epidemics had been controversial. This study systemically summarized the effects of different ways of LPM closures on H7N epidemics from previous studies, aiming to provide references for developing a better program on H7N9 control and prevention in the country.自2013年3月我国经历了5次人感染H7N9禽流感大流行，其中2016年9月至2017年6月30日内地报告病例730例。目前尽管对人感染H7N9禽流感的病原学、传播规律、流行特征尚缺乏深入了解，但现有研究提示活禽交易市场可能是病毒来源、变异、传播和感染人类的主要场所，而关闭活禽市场已成为目前防控该疫情的主要手段。但不同形式的活禽交易市场休市对人感染H7N9禽流感流行的影响仍未明确。本文综述了我国不同形式的活禽市场休市对人感染H7N9禽流感流行的影响。.

Internet data is introduced into public health arena under the features of fast updating and tremendous volume. Mining and analyzing internet data, researchers can model the internet-based surveillance system to assess the distribution of health-related events. There are two main types of internet-based surveillance systems, i.e. active and passive, which are distinguished by the sources of information. Through passive surveillance system, information is collected from search engine and social media while the active system gathers information through provision of the volunteers. Except for serving as a real-time and convenient complementary approach to traditional disease, food safety and adverse drug reaction surveillance program, Internet-based surveillance system can also play a role in health-related behavior surveillance and policy evaluation. Although several techniques have been applied to filter information, the accuracy of internet-based surveillance system is still bothered by the false positive information. In this article, we have summarized the development and application of internet-based surveillance system in public health to provide reference for a better surveillance program in China.互联网数据因其更新快和数据量丰富的特点被引入公共卫生监测领域。通过挖掘分析互联网中丰富的健康相关信息，研究者建立基于互联网的公共卫生监测系统，以快速估计人群中健康相关事件的分布。基于互联网的公共卫生监测系统根据信息来源不同可分为主动式监测系统和被动式监测系统。相较于传统监测系统，基于互联网的监测系统具有及时性佳和成本低的优点，还可在健康相关行为监测和卫生政策评价等传统监测力所不逮的领域发挥作用。但由于假阳性消息的存在，基于互联网的监测系统存在准确性不佳的缺点。本文介绍基于互联网的公共卫生监测进展及其在疾病预警中的应用，为我国开展相关工作提供参考。.

Ten sweetpotato viruses were surveyed in 3 major sweetpotato planting region (covering 11 provinces) in China from 2006 to 2010 to understand the distribution of sweetpotato viral diseases. Nine out of the 10 viruses were found in every major planting region. The most frequently detected virus in the Northern and the Yangtze River region was SPMSV. In the Southern region, SPVG was the most frequently detected virus. Compared to the results of the survey done in 1989, the incidences of all the viral diseases increased.

To date, many studies conducted in the Chinese population have determined the correlation between the tumour necrosis factor-α (TNF-α)-238G/A, -308G/A, -857C/T and -863C/A polymorphisms and persistent hepatitis B virus (HBV) infection. However, their results remain inconclusive. With the aim of confirming this correlation, we performed a meta-analysis of 19 studies. The dichotomous data are presented as the OR with a 95% CI. The results of our study indicate that carriers of the TNF-a-857T allele among the pooled Chinese population were more likely to show spontaneous clearance of HBV (T vs C: OR = 0.824, 95% CI = 0.713–0.953, p 0.009; TT vs CC: OR = 0.701, 95% CI = 0.507–0.970, p 0.032; TC vs CC: OR = 0.804, 95% CI = 0.683–0.947, p 0.009; TT + TC vs CC: OR = 0.835, 95% CI = 0.716–0.974, p 0.021). The TNF-a-308A allele was associated with significantly reduced persistent HBV infection risk in the Chinese (A vs G: OR = 0.585, 95% CI = 0.456–0.751, p 0.002; AG vs GG: OR = 0.519, 95% CI = 0.341–0.789, p
