In 2009,the World Health Organization included snakebite on the list of neglected tropical diseases,acknowledging it as a common occupational hazard for farmers,plantation workers,and others,causing tens of thousands of deaths and chronic physical disabilities every year.This guideline aims to provide practical information to help clinical professionals evaluate and treat snakebite victims.These recommendations are based on clinical experience and clinical research evidence.This guideline focuses on the following topics:snake venom,clinical manifestations,auxiliary examination,diagnosis,treatments,and prevention.

Objective:To investigate the role of survivin in the regulation of leptin expression and its sensitivity.Methods:Survivin was overexpressed in adipocytes via lentivirus, and the RNA-sequencing(RNA-seq) was used to explore the effect of survivin on the regulation of adipocyte secretory proteins. Survivin was overexpressed in the inguinal adipose tissue(iWAT) of mice by targeted injection of adeno-associated virus(AAV). The transcription levels of leptin and adiponectin were detected by realtime quantitative PCR(RT-qPCR), and the secretion levels of leptin and adiponectin in cellular supernatants and mice serum were detected by enzyme-linked immunosorbent assay(ELISA). The protein level of phosphorylated signal transducer and activator of transcription 3(STAT3) in hypothalamus was detected by Western blotting to investigate the effect of survivin on central leptin sensitivity.Results:Survivin overexpression in both 3T3-L1 and primary white adipocyte significantly down-regulated the leptin transcriptional expression without affecting the adipocyte differentiation( P<0.01). Overexpression of survivin significantly decreased leptin level without affecting the adiponectin levels in the cellular supernatant( P<0.001). Overexpression of survivin in iWAT via AAV injection, not only specifically down-regulated leptin transcriptional level in a dose dependent manner in local adipose tissue, but also led to a decrease in serum leptin level( P<0.05). In mice fed short-term high-fat diet, STAT3 phosphorylation level in hypothalamus significantly increased, suggesting improved central leptin sensitivity. Conclusion:Survivin could downregulate leptin expression and improve leptin sensitivity in high-fat diet induced obese mice.

Network Meta-analysis was used to compare the efficacy and safety of Chinese patent medicines in the treatment of unstable angina pectoris. PubMed, Cochrane Library, CNKI, Wanfang, VIP and other databases were retrieved by computers from the establishment of the databases to June 2020. Randomized controlled trials(RCTs) of Chinese patent medicines for the treatment of unstable angina pectoris were collected. Two investigators independently screened out the literatures, and extracted data according to the inclusion and exclusion criteria. The quality of the included RCTs was evaluated according to the bias risk assessment tool recommended by the Cochrane System Reviewer Manual, and the Stata 13.0 software was used for data analysis and mapping. Through screening, 28 eligible studies were finally included, with the sample size of 2 885 cases, involving 8 Chinese patent medicines. The results of the network Meta-analysis showed that in terms of total effective rate for angina symptom improvement, the order was as follows: Shenshao Capsules > Naoxintong Capsules > Ginkgo Ketone Ester Dripping Pills > Compound Danshen Dripping Pills > Ginkgo Leaf Tablets > Shexiang Baoxin Pills > Tongxinluo Capsules > Yindan Xinnaotong Soft Capsules; in terms of total effective rate for ECG curative effect, the order was as follows: Ginkgo Ketone Ester Dripping Pills>Compound Danshen Dripping Pills > Tongxinluo Capsules > Shenshao Capsules > Shexiang Baoxin Pills > Yindan Xinnaotong Soft Capsules; in terms of hypersensitivity-C-reactive protein curative effect, the order was as follows: Tongxinluo Capsules > Shenshao Capsules > Ginkgo Leaf Tablets>Compound Danshen Dropping Pills> Shexiang Baoxin Pills > Naoxintong Capsules > Yindan Xinnaotong Soft Capsules > Ginkgo Ketone Ester Dropping Pills. Chinese patent medicine combined with conventional therapy can improve the clinical efficacy of unstable angina pectoris. Due to the differences in the quantity and quality of the included studies, the order results of Chinese patent medicines need to be further verified.

Objective To establish the key question list for the development of evidencebased guideline in China according to the content and limitation of current evidence-based guidelines around the world.Methods First,we introduced the evidence-based guidelines in detail which met the criteria based on World Health Organization guideline development handbook and then formulated the draft list of key questions for the development of evidence-based guidelines.At last,the Delphi method was used to determine the list of key questions in developing evidence-based guidelines of colorectal cancer screening.Results Totally,34 questionnaires were collected,with experts from clinical and epidemiological fields.The average experts' authority coefficient was 0.81,indicating a high degree of authority.The concentration of opinions on all items in the questionnaire was relatively high,with the full score ratio greater than 75％ and the coefficient of variation less than 0.3.The list of key questions on evidence-based guidelines for colorectal cancer screening has been divided into six parts:epidemiological problems,risk classification,screening age,screening tools,implementation and selection of steering group members,which covers the issues that need to be considered in the development of evidence-based colorectal cancer screening guidelines in China.Conclusion The key question list for evidence-based guideline development in our study can be applied to the development of evidence-based guidelines for colorectal cancer screening in the future,as well as the development of evidence-based guidelines for other cancer screening in China.

Objective: To determine the hemoglobin level and blood pressure and the factors that influence their recovery in relocated workers who were unfit for duties at high altitude. Methods: The physical examination data of 693 relocated workers who previously worked at high altitude were dynamically monitored from January 2006 to June 2015 in order to examine the recovery of hemoglobin level and blood pressure. Results: The rate of hemoglobin recovery was 81.37% among the 161 relocated workers with abnormal hemoglobin levels, and the rate of blood pressure recovery was 69.51% among the 164 relocated workers with abnormal blood pressure. The rates of hemoglobin and blood pressure recovery were decreased in individuals aged 40 years and older. The peak recovery time of hemoglobin was 11-15 months following relocation, and that of blood pressure was 5-7 months and 11-13 months following relocation. The half-year blood pressure recovery rate and 2-year hemoglobin recovery rate following relocation were significantly higher in workers who worked at 2500-3000 m altitude than in those at ≥3000 m (P<0.05) . Total cholesterol and educational level were factors that influence the half-year blood pressure recovery in relocated workers (P<0.05) . Conclusion The rate of hemoglobin and blood pressure recovery are high among relocated workers who previously worked at high altitude. Factors that influence blood pressure, such as total cholesterol, should be closely monitored so that high-altitude workers with abnormal blood pressure and hemoglobin level can be relocated as early as possible.

Objective To investigate iodine nutrition status in healthy adults in Xinjiang Urumqi city and their relationship to ethnicity, gender and age. Method A cross-sectional survey was performed in 2 100 residents of Xinjiang Urumqi 2 communities in May 2013, of which 1 835 healthy adults aged 18-84 years, mean age 46.3 ± 14.2 years were enrolled. Urine iodine with arsenic-cerium catalytic spectrophotometry and salt iodine and water iodine of the residents were measured. Result The water iodine content was 3.14 μg/L, salt iodine was 27.75 mg/kg, 1 835 urine samples were collected, the urinary iodine median(MUI) was133.4 μg/L, iodine deficiency accounted for 32.37% (595 cases), iodine sufficient 42.94% (788 cases), iodine super-sufficient 14.44%(265 cases), iodine excess 10.19%(187 cases). The urine iodine level in Han ethnic group was higher than those in Uygur adults, no significant difference was observed between men and women (P>0.05). Urinary iodine levels among different age groups had no statistical difference, but in the older groups the level was lower than that in young or middle age adults. The urinary iodine level decreased gradually with the age increasing. Conclusion There was a sufficient pattern of iodine nutrition levels in healthy adults in Xinjiang Urumqi; there was a correlation between the level of iodine nutrition and the ethnicity but not with gender;iodine nutrition level in older age group was lower than those in younger age groups. Monitoring the urinary iodine continually and decreasing iodine intake may be necessary for part of iodine excess population.
