China CDC weekly 2023年第34期5卷 756-762页

作者： Jinyu Cui Yewu Zhang Hui Ge Yu Cao Xuemei Su Chinese Center for Disease Control and Prevention BeijingChina.

Introduction:This study investigates the patterns of scarlet fever among Chinese children aged 0–9 years from 2010 to 2019.The objective is to provide insights that may inform potential adjustments to China’s current prevention and control tactics for this illness.Methods:The present study utilized data on the occurrence of scarlet fever in children from 2010 to 2019,sourced from the National Notifiable Disease Reporting System database,managed by the Chinese Center for Disease Control and Prevention.This research implemented SAS9.4 software to construct trajectory models representing the temporal incidence of scarlet fever,accounting for key variables such as sex,geographic region,urban versus rural dwellings,and various age brackets.Results:From 2010 to 2019,a total of 554,695 scarlet fever cases were reported among children aged 0–9 years in the 31 mainland Chinese provincial-level administrative divisions,signifying a rate of 35.36 per 100,000 individuals.An inconsistent yet generally rising trend was observed,evidenced by a 3.17-fold increase in reported cases and a 3.02-fold escalation in incidence rate over this period.Examination of these trends revealed three distinctive developmental patterns for both males and females,with the lowest prevalence in the first trajectory and the highest in the third.The incidence was consistently higher among males than females in all trajectories.The urban and northern regions displayed equal or greater trajectory rates than their rural and southern counterparts,respectively.In terms of age groups,the lowest incidence was observed in the 0–1-year age group,while the highest was recorded in the 4–5 and 6–7-year age groups.Conclusions:Between 2010 and 2019,there was a marked increase in the incidence of scarlet fever among children in China.The disease predominantly impacts urban-dwelling children,ranging from 4 to 7 years old,in the northern regions of the country.The incidence is reported to be higher among boys compared to girls.

Zero-Shot Medical Image Retrieval for Emerging Infectious Diseases Based on Meta-Transfer Learning--Worldwide,2020

引用

China CDC weekly 2020年第52期2卷 1004-1008页

作者： Yuying Zhao Hanjiang Lai Jian Yin Yewu Zhang Shigui Yang Zhongwei Jia Jiaqi Ma School of Computer Science and Engineering Sun Yat-Sen UniversityGuangzhouGuangdongChina Center for Public Health Surveillance and Information Service Chinese Center for Disease Control and PreventionBeijingChina State Key Laboratory for Diagnosis and Treatment of Infectious Diseases Collaborative Innovation Center for Diagnosis and Treatment of Infectious DiseasesThe First Affiliated HospitalCollege of MedicineZhejiang UniversityHangzhouZhejiangChina School of Public Health Peking UniversityBeijingChina

Introduction:Due to the increasing number of medical images,image retrieval has become an important technique for medical image analytics.Although many content-based image retrieval methods have been proposed,the retrieval of images in datasets related to emerging/new infectious diseases still remain a challenge-mostly due to the lack of historical data.As a result,the current retrieval models have limited functionality in helping doctors make accurate diagnoses of new diseases.Methods:In this paper,we propose a zero-shot retrieval model based on meta-learning and ensemble learning,which can obtain a model with stronger generalizability without using any relevant training data,and thus performs well on new types of test data.Results:The experimental results showed that the proposed method is 3% to 5% higher than the traditional method,which means that our model can retrieve relevant medical images more accurately for newly emerging data types and provide doctors with more effective assistance.Discussion:When a new infectious disease occurs,doctors can use the proposed zero-shot retrieval model to retrieve all relevant cases,quickly find the common problems of patients,find the locations of the new infections,and determine its infectivity as soon as possible.The proposed method is a new computeraided decision support technology for emerging infectious diseases.

China CDC weekly 2020年第52期2卷 999-1003页

作者： Yewu Zhang Xiaofeng Wang Yanfei Li Siyu Wu Ming Wan Xuemei Su Shigui Yang Hanjiang Lai Zhongwei Jia Jiaqi Ma Center for Public Health Surveillance and Information Service Chinese Center for Disease Control and PreventionBeijingChina School of Public Health Peking UniversityBeijingChina State Key Laboratory for Diagnosis and Treatment of Infectious Diseases Collaborative Innovation Center for Diagnosis and Treatment of Infectious DiseasesThe First Affiliated HospitalCollege of MedicineZhejiang UniversityHangzhouZhejiangChina Sun Yat-sen University GuangzhouGuangdongChina

What is already known about this topic?The exact number of incident cases of emerging infectious diseases on a daily basis is of great importance to the disease control and prevention,but it is not directly available from the current surveillance system in time.What is added by this report?In this study,a Bayesian statistical method was proposed to estimate the posterior parameters of the gamma probability distribution of the lag time between the onset date and the reporting time based on the surveillance data.And then the posterior parameters and corresponding cumulative gamma probability distribution were used to predict the actual number of new incident cases and the number of unreported cases per day.The proposed method was used for predicting COVID-19 incident cases from February 5 to February 26,2020.The final results show that Bayesian probability model predictions based on data reported by February 28,2020 are very close to those actually reported a month later.What are the implications for public health practice?This research provides a Bayesian statistical approach for early estimation of the actual number of cases of incidence based on surveillance data,which is of great value in the prevention and control practice of epidemics.

目的利用地理探测器分析我国西南部分地区细菌性痢疾(菌痢)发病与气象、环境和社会经济相关因素的关系。方法利用中国传染病报告管理信息系统2005-2014年四川省、云南省和西藏自治区(西南地区)菌痢报告数据及气象数据、地形环境和社会经济因素数据,应用地理探测器模型中4种不同的工具进行数据分异性统计分析,评估疾病发病率与相关因子在空间分布的一致性,探讨不同因子对疾病分布的影响。结果通过地理探测器分析发现,自变量对因变量的解释度(powerofdeterminant,PD)最大值是平均海拔和民族,PD值分别为0.308和0.260,其次是夏季平均气温、地形、海拔标准差、坡度、人口密度,夏季平均相对湿度、夏季平均降水量、地区生产总值的PD值均<0.200。通过生态探测器发现,夏季平均降水量、地区生产总值与平均海拔、海拔标准差、坡度、地形和民族的PD值差异均有统计学意义(P<0.05)。通过交互探测器发现,夏季平均相对湿度与夏季平均气温、人口密度、地区生产总值的空间交互后PD值大于两因素PD值之和,呈现非线性叠加增强。通过风险区探测器发现,在夏季平均气温适中、夏季平均降水量少、夏季相对湿度适中、平均海拔高、海拔标准差大、坡度大、山地地形、藏缅语族居民,人口密度低、地区生产总值低的区域,菌痢发病率高。结论我国西南地区的气象条件、地形环境状况决定了地区菌痢流行的人群基础,不同经济发展水平的人群社会经济行为、卫生条件的差异则直接影响菌痢在人群间传播,最终影响菌痢发病率的高低。因此,关注社会经济手段的传播干预将有利于控制菌痢流行。

背景:研究表明,巨噬细胞的极化精确调控在组织损伤的修复进程中十分重要,肌卫星细胞增殖及分化在骨骼肌损伤的修复中也有重要作用,并显示柚皮素能改善骨骼肌损伤修复中的过度纤维化。目的:探讨柚皮素对于骨骼肌修复的作用及其机制,为用于骨骼肌损伤提供理论依据。方法:取80只10周龄SPF级SD大鼠随机分为2组(n=40),采用重物击打方法构建骨骼肌损伤模型后,实验组腹腔注射柚皮素(2μg/g)14 d,对照组注射等剂量1%二甲基亚砜。于伤后12 h及1,3,5,7,14 d分别每组采集6只大鼠腓肠肌。Masson和苏木精-伊红染色观测骨骼肌组织纤维化程度;酶联免疫吸附法(ELISA)检测炎症因子白细胞介素4、白细胞介素13、干扰素α、干扰素γ表达;实时荧光定量PCR检测促纤维化基因(Ⅰ、Ⅲ型胶原蛋白)和成肌分化抗原的m RNA表达;流式细胞术检测巨噬细胞极化程度;免疫荧光(Pax7、成肌分化抗原)染色观察肌卫星细胞增殖情况。结果与结论:(1)组织学观察:伤后5,7,14 d时实验组纤维化面积比值低于对照组(P <0.05),再生肌纤维百分比均明显大于对照组(P <0.05);(2)ELISA检测:与对照组相比,实验组伤后7,14 d白细胞介素4以及5,7,14 d时白细胞介素13和干扰素α的表达增加(P<0.05),而干扰素γ的表达出现下降;(3)实时荧光定量PCR检测:与对照组比较,实验组伤后3,5,7,14 dⅠ、Ⅲ型胶原m RNA相对表达量均下降(P<0.05);3,5,7 d成肌分化抗原m RNA相对表达量增加(P<0.05);(4)流式细胞术检测:伤后3,5,7,14 d实验组M1型巨噬细胞数量均少于对照组,而M2型巨噬细胞数量均多于对照组(P <0.05);(5)免疫荧光染色:术后3 d的实验组肌卫星细胞增殖高于对照组(P <0.05);(6)结论:柚皮素能够通过调控巨噬细胞发生M2型极化从而促进肌卫星细胞增殖的方式治疗骨骼肌损伤。
