ABSTRACT

Objective@#To investigate the contamination of phthalic acid esters (PAEs) and assess the health risk of PAEs contamination in market-available yellow rice wine in Huzhou City, Zhejiang Province, so as to provide the safety safeguard for consuming yellow rice wine.@*Methods@#Yellow rice wine samples were collected from markets in Huzhou City from 2021 to 2022, and 16 PAEs were determined in yellow rice wine using magnetic solid-phase extraction coupled with gas chromatography-tandem mass spectrometry. The carcinogenic and non-carcinogenic risks of PAEs were evaluated using the health risk models proposed by United States Environmental Protection Agency.@*Results@#A total of 75 yellow rice wine samples were collected, and 44 samples were detected with PAEs contamination (58.67%). Dimethyl phthalate (DMP), di-isobutyl phthalate (DIBP) and di-butyl phthalate (DBP) were detected, and there were 17 samples (22.67%) detected with DBP overdose (DMP and DIBP had no limit standard). DMP, DBP and DIBP, which were not classified as Class 2B and higher carcinogens by WHO's International Agency for Research on Cancer, had no definitive carcinogenic risks. Under mean PAEs, the five types of yellow rice wine all had no carcinogenic risks. Under 75% percentile of PAEs concentrations, the DBP in beverage wine with plastic packaging had a carcinogenic risk score of 1.207 5, with a gross carcinogenic risk score of 1.207 5. Under the maximum PAEs concentration, the ross carcinogenic risk scores of cooking wine with plastic packaging, beverage wine with plastic packaging, beverage wine with glass bottle packaging, and beverage wine with jar packaging were 2.751 0, 2.782 0, 1.298 2 and 2.944 0, presenting non-carcinogenic risks.@*Conclusion@#There is PAEs contamination in market-available yellow rice wine in Huzhou City, and no carcinogenic risk is evaluated. Non-carcinogenic health risk requires to be given a high priority.

ABSTRACT

Objective @#To analyze the influencing factors for the molecular network transmission clusters of HIV/AIDS, and to provide scientific evidence for the precise prevention and control of AIDS. @*Methods@#A case-control study was conducted. The HIV/AIDS cases reported from January 2017 to June 2019 in Huzhou with strong clustering of HIV molecular transmission were recruited as the case group, and the residents with same gender, similar age ( ±three years ) and HIV negative in the same community and period were matched ( 1∶4 ) as the control group. Demographic characteristics, AIDS related knowledge and sexual behaviors were collected by a questionnaire survey. The Cox regression model was used to analyze the influencing factors for HIV/AIDS molecular network transmission cluster.@*Results @#There was 100 people in the case group and 400 people in the control group, the differences between them in age, sex, marital status, place of residence and educational level were not statistically significant ( P>0.05 ) . The results of multivariate Cox regression analysis showed that awareness of AIDS related knowledge ( HR=0.145, 95%CI: 0.059-0.352 ) was a protective factor for molecular network transmission clusters of HIV/AIDS; men who have sex wth men ( MSM, HR=9.614, 95%CI: 4.645-19.901) , seeking homosexual partners through the internet (HR=16.321, 95%CI: 7.016-32.968) and having syphilis ( HR=3.314, 95%CI: 1.073-10.232 ) were risk factors for molecular network transmission clusters of HIV/AIDS.@*Conclusions@#The awareness of AIDS related knowledge, MSM, seeking homosexual partners through the internet and suffering from syphilis are the influencing factors for molecular network transmission clusters of HIV/AIDS.

ABSTRACT

Objective@#To learn the epidemiological characteristics of coronavirus disease 2019(COVID-19)in Huzhou,so as to provide reference for prevention and control of COVID-19.@*Methods@#All the confirmed cases of COVID-19 in Huzhou,diagnosed according to the COVID-19 Diagnosis and Treatment Plan(Sixth Version Trial)and reported from January 25 to February 7,2020,were recruited. The process of diagnosis and treatment,clinical manifestation,exposure history and close contacts were collected to analyze the epidemiological characteristics. @*Results@#On January 25,the first confirmed cases of COVID-19 in Huzhou was reported. By February 7,totally 10 confirmed cases were reported and no asymptomatic infection was found. They were all imported,including three Wuhan residents,two with a trip to Wuhan,three with a trip to Suizhou,one with a trip to Hangzhou and one with a trip to Thailand(two Wuhan passengers on the same flight). The ratio of male to female cases was 1∶1. The median age was 32 years old. Seven cases were found when they went to a doctor by themselves,and three cases were found during the quarantine. The main clinical manifestations were fever,dry cough and fatigue. The median time from onset to diagnosis was 3 days. By March 3,all the cases were discharged,with median course of 24 days. There were 312 close contacts,and all of them were released after 14 days of quarantine. @*Conclusions @#To prevent imported cases from outside and stop spread inside taken by Huzhou government was proved to be effective. All the COVID-19 cases in Huzhou were imported,mostly from Wuhan. No local cases were reported.
