Objective Lyme disease and Human granulocytic anaplasmosis are tick-borne diseases caused by Borrelia burgdorferi and Anoplasrna phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum. Methods Forest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay （IFA）. Results Seroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces （the exception being the Miyun area in Beijing）. The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks. Conclusion We conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces.

Objective To develop a risk model for predicting later development of diabetic nephropathy （DN） in Chinese people with type 2 diabetes mellitus （T2DM） and evaluate its performance with independent validation. Methods We used data collected from the project ＇Comprehensive Research on the prevention and control of Diabetes＇, which was a community-based study conducted by the Jiangsu center for disease control and prevention in 2013. A total of 11,771 eligible participants were included in our study. The endpoint was a clear diagnosis of DN. Data was divided into two components： a training set for model development and a test set for validation. The Cox proportional hazard regression was used for survival analysis in men and women. The model＇s performance was evaluated by discrimination and calibration. Results The incidence （cases per 10,000 person-years） of DN was 9.95 （95% CI; 8.66-11.43） in women and 11.28 （95% CI; 9.77-13.03） in men. Factors including diagnosis age, location, body mass index, high-density-lipoprotein cholesterol, creatinine, hypertension, dyslipidemia, retinopathy, diet control, and physical activity were significant in the final model. The model showed high discrimination and good calibration. Conclusion The risk model for predicting DN in people with T2DM can be used in clinical practice for improving the quality of risk management and intervention.

Immunotherapy, as a groundbreaking cancer treatment, has gained considerable attention for its utilization of the body’s immune system to combat tumors [1]. This therapy induces tumor cell apoptosis, triggering a sustained anti-tumor immune response and effectively preventing tumor recurrence and metastasis [2]. The fundamental principle lies in inducing tumor cell death through specific treatment modalities, leading to the release of a cascade of signaling molecules and antigens, thereby mobilizing the immune system to actively identify and attack tumor cells [3].

On December 14, 2017, a faculty member of a university in hunan Province reported that an anthrax vaccine strain might have recovered virulence during an undergraduate experiment and potential exposure could not be ruled out for the students involved. Upon receiving the case report, the CDC, health bureaus, and local governments at the county, prefectural, and provincial levels promptly organized experts in different fields (including epidemiologists, biosafety experts, and laboratory testing experts) for case investigation, evaluation, and response. As the investigation results showed, no virulence recovery was identified in the involved anthrax vaccine strain;and no contamination of Bacillus anthracis was detected at the involved areas. Thus, the university returned to normal functioning.

Objective To construct a rapid and high-throughput assay for identifying recombinant bacteria based on mass spectrometry. Methods Matrix assisted laser desorption ionization time-of-flight mass spectrometry （MALDI-TOF MS） techniques were used to identify 12 recombinant proteins （10 of Yersinia pestis, 1 of Campylobacter jejuni and 1 of Helicobacter pylori）. A classification model for the various phase of recombinant bacteria was established, optimized and validated, using MALDI-TOF MS-CIinProTools system. The differences in the peptide mass spectra were analyzed by using Biotyper and FIexAnalysis softwares. Results Models of GA, SNN, and QC were established. After optimizing the parameters, the GA recognition model showed good classification capabilities： RC=100%, mean CVA=98.7% （the CVA was 96.4% in phase 1, 100% in phase 2, 98.4% in phase 3, and 100% in phase 4, respectively） and PPV=95}. This model can be used to classify the bacteria and their recombinant, which only requires 3.7x103 cells for analysis. The total time needed is only 10 min from protein extraction to reporting the result for one sample. Furthermore, this assay can automatically detect and test 96 samples concurrently. A total of 48 specific peaks （9, 16, 9, and 14 for the four stages, respectively） was found in the various phase of recombinant bacteria. Conclusion MALDI-TOF MS can be used as a fast, accurate, and high-throughput method to identify recombinant bacteria, which provide a new ideas not only for recombinant bacteria but also for the identification of mutant strains and bioterrorism pathogens.

Abstract Objective To identify and type three leptospires isolated from Rattus tanezumi in Guizhou Province by using three molecular techniques （PFGE, MLVA, and MLST）, reveal the molecular characteristic of causative agents of local leptospirosis and evaluate these three molecular methods based on their detection resolution and efficiency. Methods Three Leptospira strains were isolated from the kidney of Rattus tanezumi and cultured with EMJH medium. PFGE, MLVA, and MLST assays were applied to type the three strains isolated from Rattus tanezumi in Guizhou Province. Results PFGE, MLVA, and MLST typing showed that the three leptospiral isolates matched with leptospiral serogroup Icterohaemorrhagiae serovar Lai. The findings of the genotyping methods were consistent. MLVA and MLST defined genotypes, whereas PFGE allowed the recognition of additional subgroups within the genotypes, and the findings of molecular typing were also consistent with those of traditional techniques. Conclusion Three leptospiral isolates from Guizhou Province matched with leptospiral serogroup Icterohaemorrhagiae serovar Lai, and PFGE, MLVA, and MLST, as reliable molecular techniques for identifying and typing of Leptospira interrogans, would contribute to the active surveillance, outbreak investigation and source tracking for leptospirosis in Guizhou Province.

作者： ZHANG Xia Yan HUANG Tao FENG Yi Bing LI Meng CHEN Fang Fang LI Yin Ge JIN Shan Shan BU Kai WANG Lu National center for AIDS/STD control and prevention Chinese Center for Disease Control and Prevention Shandong provincial center for disease control and prevention College of Public Health University of South Florida

Objective To describe the characteristics of the HIV/AIDS epidemic in women aged 15-49 years in China. Methods HIV/AIDS cases from 2005 to 2012 that fulfilled the inclusion and exclusion criteria were identified on the Chinese HIV/AIDS case reporting system. Descriptive and spatial analyses were performed. Results A total of 103,559 female HIV/AIDS cases were included in our study. Based on the descriptive analysis, between 2005 and 2012, the proportion of heterosexually acquired HIV infection among women （15-49 years） increased rapidly from 35.8% to 87.4%. Approximately 60% of these cases were infected through non-marital heterosexual contact. Among older women （40-49 years）, a slightly increasing trend was identified. The spatial analysis detected ＇hot spots＇ in the Xinjiang, Yunnan, Sichuan, Guangxi, and Chongqing provinces. The epidemic trends in these areas were predominately driven by heterosexual transmission. Conclusion Non-marital heterosexual contact is a very important factor in the HIV/AIDS epidemic in women aged 15-49 years, and the HIV infection rate in older women is increasing. Several epidemic hot spots were detected in northwestern and southwestern China. Efficient interventions are needed to control the spread of HIV/AIDS among women living in these areas.

Dimethylacetamide-induced Hepatic Injury in Vitro: Mechanism and Potential Preventive Strategy

引用

Biomedical and Environmental Sciences 2016年第2期29卷 153-157页

作者： LIU Xin GONG Wei XU Yan Qiong ZHU Bao Li Institute of Occupational disease prevention Jiangsu Provincial Center for Disease Prevention and Control

N,N-Dimethylacetamide （DMAc） is a widely used organic solvent in modern chemical industry with low to moderate hepatotoxicity to occupational health of employees. But so far, there are fewer and less conclusive data concerning its pathogenic mechanism in detail. In current study, the toxicity of DMAc was firstly investigated on human normal hepatocytes （LO-2）, using a series of molecular biology measurements to ananlyze the effect and mechanism of DMAc-induced hepatic cell injury and explore effective prophylactic measures. We found that DMAc triggered LO-2 apoptosis in a obviously dose-dependent manner, caused by increased ROS generation and activation of Bcl-2 pathway. Significantly, glutathione （GSH） rather than vitamin C （Vit C） could partially inhibit DMAc-induced apoptosis thus showing potential as a effective precaution for workers.
