ABSTRACT
OBJECTIVE：To systematically evaluate the effects of phenytoin on 3 kinds of cardiovascular disease-related factors （Folic acid ，vitamin B 12 and homocysteine）in epilepsy patients ，and to provide evidence-based reference for clinical treatment of epilepsy. METHODS ：Retrieved from PubMed ，Google scholar ，CJFD，VIP and Wanfang database ，observational studies about using phenytoin （trial group ） versus using no antiepileptics （control group ） on the levels of folic acid ，vitamin B 12 and homocysteine in serum were collected during Jan. 1991-Jan. 2019. After data extraction of included literatures ，quality evaluation with evaluation criteria for cross-sectional study （AHRQ）scale，Rev Man 5.3 and Stata 11 softwares were used for statistical analysis. RESULTS ：A total of 10 studies were included ，involving 745 patients. Meta-analysis showed that the folic acid level of trial group was significantly lower than control group [SMD ＝－0.90，95％CI（－1.18，－0.62），P＜0.001]；the level of homocysteine in trial group was significantly higher than control group [SMD ＝1.22，95％CI（0.73，1.71），P＜0.001]. There was no significant difference in the levels of vitamin B 12 between 2 groups [SMD ＝－ 0.19，95％ CI（－ 0.39，0.02），P＞0.05]. CONCLUSIONS：Phenytoin can reduce the level of folic acid and increase the level of homocysteine in epilepsy patients.
ABSTRACT
Objective To understand the status of knowledge awareness rates and influencing factors of clonorchiasis among the residents in 4 counties(cities)of Hunan Province,so as to provide the references for formulating the prevention and control strategy of clonorchiasis in the province. Methods A total of 1224 subjects were selected by the multi-stage cluster sampling method and investigated with questionnaires and face-to-face interviews. Results The clonorchiasis knowledge awareness rates of the residents were 15.67% in Yongzhou City,9.94% in Yueyang City,13.25% in Wangcheng County,and 21.96% in Tongd-ao County,respectively. In the whole province,the clonorchiasis knowledge awareness rates of the residents were 44.67%, 56.43%,60.95%,and 42.46% in the etiology,clinical manifestations,epidemiological characteristics and daily prevention,re-spectively. The logistic regression showed that the influencing factors of clonorchiasis knowledge awareness rates were the daily dining place,whether or not having the medical personnel in the family,the degree of attention to the relevant news reports, and the history of parasitic diseases. Conclusions The level of clonorchiasis than that in other areas,but the overall level of clonorchiasis knowledge awareness of the residents in Hunan Province is not high. Therefore,the relevant authority should strengthen the health education in clonorchiasis prevention knowledge including personal daily food hygienic knowledge. knowl-edge awareness rate of the residents in the west-southern areas of Hunan Province is higher
