Objective To analyze the epidemiological characteristics of hospital admission cases with chemical poisoning in Guangdong Province from 2016 to 2020. Methods Data of hospital admissions for chemical poisoning in Guangdong Province from 2016 to 2020 were collected through Guangdong Province Health Statistics Network Reporting System，and descriptive analysis was conducted. The seasonal characteristics of the number of hospitalized poisoning cases were analyzed by the concentration method，the seasonal index（SI）was calculated by the weighted annual ratio averaging method，and the spatial auto-correlation of regional poisoning trend was analyzed by the global and local spatial autocorrelation. Results From 2016 to 2020，the number of hospital admissions for chemical poisoning in Guangdong Province was 54 656，showing a general decreasing trend. The sex ratio（male to female）was 0.90 ∶1.00. The top three types of hospitalization rates were carbon monoxide poisoning，alcohol poisoning and organic solvent poisoning. The main poisoning groups were students and children， farmers，workers and unemployed people，accounting for 31.74%，18.53%，13.91% and 10.39%，respectively. The 74.37% of poisoning cases were cured or improved and discharged，and the case fatality rate was 0.48%. The top three hospitalization rates in age group of 0-<5 years were organic solvent，metal and carbon monoxide poisoning. The hospitalization rate of carbon monoxide poisoning ranked the first among all age groups of ≥5 years. The top three regions with the highest average annual hospitalization rate were Shaoguan City （25.14/105 ），Qingyuan City （17.04/105 ） and Meizhou City （16.09/105 ）. Carbon monoxide poisoning had a strong seasonality（M=0.77），with high incidence months of January，February and December（SI were 3.60，3.08 and 2.48，respectively）. The inpatients with chemical poisoning showed non-random distribution and spatial correlation（all P<0.01），with a high-high clustering among 13 districts and counties in northern Guangdong（all P<0.05）. Conclusion The number of hospital admission cases of chemical poisoning showed an overall decreasing trend in Guangdong Province from 2016 to 2020. The main types of poisoning were carbon monoxide poisoning，alcohol poisoning and organic solvent poisoning. The spatial distribution of chemical poisoning types showed spatial correlation and there were high-high clustering areas.

Objective To investigate whether human breast milk may bind to hepatitis B surface antigen (HBsAg) and its characteristics.Methods Breast milk samples from five women with negative HBsAg and hepatitis B surface antibody (anti-HBs) at one to two months post delivery were fractioned into cream and skimmed milk by centrifugation.The human breast milk and each fraction as well as cow and goat milk samples,served as controls,were separately incubated with highly purified yeast recombinant HBsAg,followed by determination of their binding capability to HBsAg by enzyme linked immunosorbent assay (ELISA) and the inhibition rate for binding of HBsAg to anti-HBs by quantitative chemiluminescence microparticle immunoassay.After boiled for 1 min or pasteurized in 65 ℃ for 30 min,the thermal stability of the active components of milk was detected.One-way ANOVA and SNK tests were performed for statistical analysis.Results The operative concentration of HBsAg was 0.1 μg/ml.Breast milk from all five women showed significantly better binding capability to HBsAg than cow or goat milk (1.306±0.300 vs 2.157±0.150 and 2.232±0.093,F=34.303,P＜0.01).The quantitative experiments showed that the inhibition rate of human breast milk was higher than that of the control group [(74.26± 17.26)％ vs (0.00±5.50)％,F=57.806,P＜0.01].The binding ability to HBsAg of skimmed milk was comparable with that of whole milk,indicating milk protein(s) played critical roles in binding to HBsAg (0.877 ± 0.486 vs 0.513 ± 0.069 and 0.376 ± 0.146,F=44.475,P＜0.01).After boiled for 1 min or Pasteurization,the binding ability to HBsAg of whole breast milk remained,but that of skimmed milk went down (F=16.598,P＜0.01).Both whole breast milk and skimmed milk could inhibit the binding of HBsAg to anti-HBs (F=278.341 and 269.408,both P＜0.01).Conclusions The inhibition of binding to HBsAg by human breast milk indicates that human milk may interact with HBsAg.The active components mainly exist in milk proteins and are thermal stable.

Objective: To investigate the protective effect of shenduqing Granules on chronic renal insufficiency in rats. Methods: The rat model of chronic renal insufficiency was made by feeding 0.75% adenine forage. The blood biochemical indexes, ion concentration in serum of rat was measured and the pathological changes of rat kidney were observed. Results: Shenduqing Granules obviously increased thymus index (TI). The weight of rat kidney in the treatment group was lighter than that of the model group. The kidney histomorphological study showed that Shenduqing Granules obvionsly reduce the pathological changes. The drug crystals were also reduced. Conclusion: Shenduqing Granules has the potential protection against chronic renal insufficiency in rats.
