Objective To observe the anti-influenza effect of a Chinese medicinal herb-Antiviral Agent No.1. Methods To study t he anti-viral effect of Antiviral Agent No.1 by means of the technique of cel l culture and using Ribavirin as a positive control. Results In MDC K cu lture, Antiviral Agent No.1 was found to be a potential inhibitor of influenza A 3 virus in a concentration-dependent manner, with a TC50 of 60.53 mg*m l-1. When drug was added 2 hours post virus infection, the EC50(TI) was 5.14 mg*ml-1(11.78); while drug was added 2 hours before infection, t he EC50(TI) was 5.20 mg*ml-1(11.65). Conclusions Antiv iral Agent No.1 had a significant anti-influenza effect on type A3 in MDCK.

Objective To understand the prevalence of unsafe riding practice among electric bicycle riders,and to provide scientific basis for intervention strategies in Ma'anshan city of Anhui Province.Methods Observational method was used to observe electric bicycle riders' behavior of running red light,wearing a helmet,and manned act.The radar speed measuring instrument was used to measure the speed of electric bicycle.Results The rate of electric bicycle riders' running red light was 13.09％ (1 285/9 815),helmet wearing rate was 5.90％ (1 510/25 576),and manned rate was 20.28％ (5 187/25 576).The average speed was 24 ki/h,and the electric bicycles whose speed were ＞ 20 km/h accounted for 74.60％.There were significant differences in the running red light rate,helmet wearing rate and the average speed of travel among different time periods and dates (all P ＜ 0.05).More running the red light occurred during 13:30-14:30 and 15:00-16:00.Less helmet wearing occurred during 10:00-11:00 and 08:30-09:30.The periods with highest average speed were at07:00-08:00,08:30-09:30,11:30-12:30,and 13:30-14:30,which was 24 km/h.The helmet wearing rate of females (6.54％) was higher than that of males(5.46％),the men's average speed (24 km/h) was higher than women's (23 ki/h),and the differences were both statistically significant(all P ＜ 0.001).Conclusion The electric bicycle riders in Ma'anshan city of Anhui Province have the dangerous behavior of running red lights,not wearing a helmet,manned act and speeding.Targeted interventions should be taken to reduce the occurrence of related risk behaviors.

Objective To evaluate the health-related quality of life (HRQOL) and its influencing factors in pa tients with cervical cancer.Methods 120 inpatients with cervical cancer at Yunnan Tumor Hospital were investigated by functional assessment of cancer therapy-cervix (FACT-Cx),t-test,analysis of variance and multiple linear regression were used to analyze factors influencing the HRQOL.Results The total HRQOL score of patients was (104.88 ± 19.51),and the domain scores of physical well-being (PWB),social/family well-being (SWB),emotional well-being (EWB),functional well-being (FWB),cervical cancer subscale (CxS) were (20.41 ± 5.46),(17.17 ± 6.10),(15.73 ± 5.06),(13.34 ±5.83),(38.23 ±6.26),respectively.Based on multiple linear regression,the influencing factors of PWB were marital status and clinical stages,the influencing factor of SWB was marital status,the influencing factors of EWB were education levels and clinical stages,the influencing factors of FWB,CxS and total score were all marital status,clinical stages and education levels.Conclusions The HRQOL scores were influenced by a number of factors and it is significant to improve HRQOL in patients with cervical cancer by relieving symptoms and reducing treatment side effects according to patients' specialty,also psychological support and encouragement was essential.

Objective Hepatitis C virus patients are often accompanied by insulin resistance and diabetes.To probe the relative factors of abnormal glycometabolism in chronic HCV infections.Methods A total of 1 039 treatment-naive patients that were confirmed chronic HCV infected were enrolled in the study.The demographics,biochemical index parameters and other data about liver function and HCV viral load were got from infectious disease department of Jurong Pepole's Hospital in China.Results A total of 140 (13.5％) patients were diagnosed with some forms of abnormal glycometabolism.The body mass index (BMI) (x2 =9.231,P =0.010),waist circumference (x2 =7.984,P =0.018),systolic blood pressure (x2 =16.366,P ＜0.001),diastolic blood pressure (x2 =13.970,P =0.001),alanine aminotransferase(ALT) (x2 =4.809,P =0.028),HCV-RNA viral load (t =-3.818,P ＜0.001) were significantly different between non-diabetic HCV patients and abnormal glycometabolism patients.Multivariate logistic regression analysis showed that ALT(OR =2.986,95％ CI:1.171-7.615) and HCV-RNA viral load (OR =2.061,95％ CI:1.165-3.644) were found as risk factors in multivariate regression analysis for patients with chronic hepatitis C who had abnormal glucose metabolism.Conclusions Chronic hepatitis C patients with higher ALT and HCV-RNA level were more probably to suffer from abnormal glycometabolism.In order to find potentially novel risk factors of HCV with abnormal glucose metabolisn,further studies about genetic and other clinical factors need to be processed.
