ABSTRACT
Objective To evaluate the safety of two types of enterovirus 71(EV71) inactivated vaccine (Vero cell vs. Human Diploid cell) after inoculation. Methods Subjects were children vaccinated EV71 vaccine between November 2016 and May 2017 at vaccination clinics in Xiacheng District. According to the type of EV71 vaccine, subjects were divided into the Vero Cell group and the Human Diploid Cell group. The adverse effects were collected after 30 min, 3 days and 30 days of injection, respectively. Results A total of 3158 vaccinated children were observed, with 1529 in Vero Cell group and 1629 in Human Diploid Cell group. The rates of adverse effects were 0.59％ (9 cases) of Vero cell group and 0.55 ％ (9cases) of Human Diploid Cell group. All of the adverse effects were systemic reactions such as fever, diarrhea and vomiting. No significant differences were observed between the two groups above in the incidence and severity of adverse effects(P >0.05) . The incidence and severity of adverse effects of the first dose were significantly higher than the second dose in two groups (P<0.05) . Conclusion EV71 vaccine was safe to vaccinate, and no statistical difference in the adverse effects was found between the two types of vaccine.
ABSTRACT
Objective To analyze the association between baseline level of CD4+T and the therapeutic effects of highly active antiretroviral therapy (HAART) for MSM HIV/AIDS in Hangzhou City. Methods We recruited MSM HIV/AIDS who initiated HAART from July 1st 2014 to June 30th 2016 into the study in Hangzhou City. MSM HAART patients whose baseline CD4+T≥500 copies/μL was set as observation group, and baseline CD4+T<500 copies/μL was set as control group. Patients were tested CD4 count and viral load regularly. We compared HAART effects of observation group and control group. Results We recruited 1206 MSM patients with access to HAART in our study in Hangzhou City. And 1026 patients were set in control group, and 180 patients were set in observation group. In the 12th month, the rates of two groups' patients with CD4 successfully recovered (reached 719 cells/μL) were 12.50% and 39.13%. In the 18th month, the rates were 13.75% and 38.71%. The median time of patients with CD4 first successfully recovered to 719 cells/μL was 7.2 month s in observation group, while the median time of control group was 20.4 months, which was longer than observation group (P<0.05) . A total of 375 patients were tested viral load, and the successful suppression rate of viral load was 97.33%. The rates of observation and control group were 96.34% and 97.50% (P>0.05) . Conclusion The rates of viral successful suppression were similar between baseline CD4 counts ≥500 cells/μL group and<500 cells/μL group among MSM HAART patients. Recovery time in baseline CD4 counts ≥500 cells/μL group was shorter than baseline CD4 counts<500 cells/μL group.
ABSTRACT
Objective To investigate the prevalence of non - communicable diseases(NCD)among immigrants in Xiacheng district in Hangzhou city and to provide a scientific evidence for the development of prevention and control measures. Methods Using multi - stage cluster sampling method,immigrants were recruited. A face - to - face interview was conducted using structured questionnaire including general condition,smoking,drinking,physical exercise and life satisfaction. Meanwhile,height,weight,waist circumference,blood pressure,blood glucose and blood lipids were examined. The risk factors of NCD were analyzed using univariate and multivariate logistic regression. Results A total of 303 immigrants aged over 18 years were randomly selected from 5 industries in Xiacheng district,Hangzhou. The prevalence rate of NCD among immigrants was 39. 60% ,and the prevalence rates of hypertension,diabetes,dyslipidemia, chronic obstructive pulmonary disease(COPD),asthma,cancer,bone and joint disease,cervical or lumbar disease were 16. 17% ,2. 97% ,28. 71% ,0. 99% ,0. 33% ,0. 66% ,3. 30% ,3. 63% , respectively. There were significant differences in the prevalence among immigrants of different industry,gender,age,education,marriage,body mass index (BMI),waist circumference,living environment,peasant - workers time and working way( P < 0. 05). Unconditional multivariate logistic regressions showed that accommodation and catering,social services,female,junior middle school and above were the protective factors,however overweight,obesity and waist circumference(male above 85 cm or female above 80 cm)were the risk factors. The odds ratios were 6. 112,11. 321,and 2. 315 respectively. Conclusion The prevalence rate of NCD among immigrants was high in urban area of Hangzhou city. Intervention strategy should be implemented timely in order to control the development of NCD according to the prevalence of different industry and related risk factors.
