Objective To compare the efficacy of vidarabine monophosphate and ribavirin for treating hand-foot-mouth disease (HFMD) in children.Methods 120 children with HFMD and admitted to a hospital from April 2013 to April 2015 were randomly divided into observation group and control group,60 cases in each group,observation group treated with vidarabine monophosphate,control group treated with ribavirin,the therapeutic efficacy between two groups were compared.Results After treatment,the negative conversion rate of intestinal virus EV and EV71,as well as Coxsackie virus A16(CA16) in observation group were 87.0%,85.7%,and 93.1% respectively,in control group were 64.0%,69.8%,and 78.6% respectively,difference between two groups was statistically significant (all P<0.05).The average length of hospital stay in observation group was shorter than control group ([4.5 ± 1.3] days vs [6.2 ± 1.2] days,P<0).05),symptom(fever,stomatitis,skin rash) control time in observation group were all shorter than control group(all P<0.05).Whether patients with or without complication,therapeutic effect of the observation group was better than that of control group;myocardial enzyme data,C reactive protein (CRP),and white blood cell(WBC) in observation group were all lower than control group(all P<0.05).Conclusion Efficacy of vidarabine monophosphate for treating children with HFMD is better than ribavirin,but it needs further study.

In order to evaluate the moUuseicidal effect of 50% wettable power of niclosamide ethanolamine salt(WPN)combined with urea against Oncomelania snails in the field,4 g/m~2 WPN,4 g/m~2 WPN+20 g/m2 urea and 4 g/m~2 WPN+30 g/m~2 urea were used for mollusciciding with the spraying method.The results showed after 7 days,the mortality rates of snail were 74.43% for 4 g/m~2 WPN,90.32% for 4 g/m~2 WPN+20 g/m~2 urea and 94.83% for 4 g/m~2 WPN+30 g/m~2 urea,respectively.It is indicated that WPN combined with urea can improve the molluscieidal effect significantly.

OBJECTIVETo investigate the risk factors for congenital external malformation.
METHODSA 1:2 matched case-control study was conducted with 52 cases of congenital external malformation during perinantal period collected from surveillance in Baoan District of Shenzhen City from January to June in 2000.
RESULTSSimple and multiple conditional logistic regression analysis showed that the major risk factors for congenital external malformations during perinatal period were preterm labor (beta(k) = 1.4171, s(theta, beta(kappa)) = 0.4601, OR = 4.115), adverse mental stimulus (beta(kappa) = 2.1870, s(theta beta(kappa)) = 0.7873, OR = 8.909), taking medicine (beta(k) = 1.9178, s(theta beta(kappa)) = 0.8072, OR = 6.808) and exposure to hazardous chemicals during early pregnancy (beta(k) = 0.9602, s(theta beta(kappa)) = 0.4262, OR = 2.612).
CONCLUSIONSCongenital external malformation during perinatal period was caused by multiple risk factors and results of the study showed that environmental and mental factors were in obvious connection with its occurrence.
