    Abstract Objectives: Acute kidney injury (AKI) is a loose set of kidney diseases accompanied by a variety of syndromes, which is a serious threat to human life and health. Some alkaloids are derived from various Chinese herbs have been widely concerned in the improvement of AKI. This review provides the research progress of alkaloids in AKI experimental models and discusses the related molecular mechanisms.
    Conclusion: Alkaloids have been shown to significantly improve AKI, but only in pharmacological studies. This paper summarizes the main experimental models currently used in AKI research and describes some representative alkaloids based on recent research. Their potential roles in the prevention and treatment of AKI through different mechanisms are highlighted.

    Abstract Objective: To explore the present situation on the strategy of oral polio vaccine (OPV) supplementary immunization for eliminating polio and to analyses new trends and directions of these studies in China.
    Methods: Literatures on the strategy of OPV supplementary immunization for eliminating polio in china from 1993-2007 were analysed by quantitative study.
    Results: 279 papers were identified through searching papers, which were gradually increasing between 1993-2007. There were a group of active and talented authors whose papers were mainly distributed in Beijing, Guangdong, Shandong, Zhejiang province, etc. Most of papers were published in Chinese journal of vaccines and immunization, Chinese journal of public health, Chinese journal of epidemiology, etc. The review on the OPV supplementary immunization, monitoring the GMT and maintaining the progress of free-polio, etc. were involved.
    Conclusion: There were also problems on the imbalance of the region distribution, the limitation of institution, the lower level of study methods and the insufficient study content about the strategy of OPV supplementary immunization. The coorporation between CDC and the medicine institution should be conducted. It is very important to evaluate the cost-effective and the methods of the strategy of OPV supplementary immunization.

    Abstract Objectives: To describe epidemiological trends and spatial distributions of HIV/AIDS among older adults (aged ≥50) in Sichuan Province, China during 2008-19, and provide scientific reference for HIV/AIDS prevention, intervention and treatment.
    Methods: Data on HIV/AIDS cases reported in 2008-19 was extracted from the Case Report System. The Cochran-Armitage trend test was used to determine epidemic trends. Spatial autocorrelation and space-time analysis were conducted with ArcGIS10.6 and ArcGIS Pro2.4, respectively.
    Results: A total of 77854 HIV/AIDS cases among older adults were included in the study. Newly reported cases increased from 320 in 2008 to 22189 in 2019, and the reported incidence rate (number of new reported cases/older adult population) rose from 0.001% to 0.077%. Infections through heterosexual transmission increased from 65.3% to 98.2% of total cases in older adults in this period. Spatial analysis at the county-level showed significant clustering throughout Sichuan, with the main hot spots concentrated in the southeast. Spatiotemporal analysis indicated that most of the southeastern counties/districts were Consecutive Hot Spots.
    Conclusions: Older adults have become a key population in the HIV/AIDS epidemic in Sichuan; comprehensive prevention and intervention measures targeted to older adults are urgently needed to control the spread of HIV/AIDS.

    Abstract Objective: To investigate the status and influencing factors of the knowledge and behavior related to brucellosis among occupational workers in Jianyang city, and to provide basic information for developing regional specific strategies for brucellosis prevention and control.
    Methods: With multistage cluster random sampling, occupational workers aged ≥18 yr. who had been in contact with sheep and their products were interviewed through a questionnaire about demographic characteristic, knowledge, and behavior related to brucellosis. The knowledge and practice scores were described as frequency and percentage, and the awareness rate of knowledge about brucellosis was calculated. Unconditional logistic regression model was used to analyze the influencing factors of knowledge and behavior related to brucellosis.
    Results: In total, 378 workers were recruited. The minority (25.1%) of the workers had heard of brucellosis, and the awareness rate of brucellosis was 22.0%. Occupational protective behaviors were poor, and the scoring rates of wearing protective clothes, mask and gloves were 58.7%, 76.5%, 71.7% respectively. The results of multivariate logistic regression analysis revealed that the awareness rate of knowledge about brucellosis decreased with age, while the low educational level was found to be associated with low awareness of knowledge about brucellosis, and occupation type had association with the awareness rate of knowledge. Besides, the awareness of knowledge about brucellosis was a protective factor and occupation type were associated with the behavior related to brucellosis.
    Conclusions: The knowledge and behavior related to brucellosis are poor among occupational workers in Jianyang. It is necessary to continuously implement targeted health education and health promotion programs in this region, and the people with low education level and livestock farmers should be paid special attention to.

    Abstract This review summarizes the ongoing researches regarding etiology, epidemiology, transmission dynamics, treatment, and prevention and control strategies of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with comparison to severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and pandemic H1N1 virus. SARS-CoV-2 may be originated from bats, and the patients and asymptomatic carriers are the source of epidemic infection. The virus can be transmitted human-to-human through droplets and close contact, and people at all ages are susceptible to this virus. The main clinical symptoms of the patients are fever and cough, accompanied with leukocytopenia and lymphocytopenia. Effective drugs have been not yet available thus far. In terms of the prevention and control strategies, vaccine development as the primary prevention should be accelerated. Regarding the secondary prevention, ongoing efforts of the infected patients and close contacts quarantine, mask wearing promotion, regular disinfection in public places should be continued. Meanwhile, rapid detection kit for serological monitoring of the virus in general population is expected so as to achieve early detection, early diagnosis, early isolation and early treatment. In addition, public health education on this disease and prevention should be enhanced so as to mitigate panic and mobilize the public to jointly combat the epidemic.

    Abstract Enterovirus 71 is the main pathogen that causes severe and fatal hand-foot-mouth-disease (HFMD) cases. As the enterovirus virus mutation has implications for pathogenesis, vaccine development, antiviral therapy, and epidemiological disease management of the virus. In this study, we investigated the variations of enterovirus 71 in thermal adaption, using the method of adaptive laboratory evolution. The sibling virus strains were isolated from a 2-year-old severe case of HFMD (#100) and her symptomless close contact (#101). Both strains were cultured in Vero cells by serial passage of 36 generations at the temperatures of 28.0 °C, 33.0 °C and 39.5 °C to construct adaptive lineages. According to the comparative analysis of phenotypes between adapted strains and parental strains, differences in growth rate were observed in the sibling lineages and a larger plaque was found mainly in the hot adapted strains for lineage #101. Two sets of adaptive strains from six time points (parental, 12th 17th, 31st, 35th passage and endpoint) were sequenced and analyzed by both Sanger sequencing and Next Generation Sequencing. Several variations in most coding genes and one reverse mutation in 5'UTR was observed, along with the identity of 99.8% for complete genome for both lineages. Notably, thermal specific non-synonymous mutations were found in the gene of VP1\VP3\3A\2C\3C. Moreover, the concurrent mutations A292G, A434G and A355C/T of sibling lineages in VP1 showed quantificational trace with distinguishing patterns for different temperatures, which were suspected to be the thermo-sensitive mutation hotspots. These results highlight the possible rules of thermal adaption in enterovirus 71, produce a novel picture of genome evolution of the virus, and shed light on viral variation and evolution.
