Objective To investigate the risk factors of ischemic stroke in Jiangsu Taixing population.Methods Case-control study was used in this investigation.Cases: all the diagnosed ischemic stroke patients in neurology department of Taixing People 's Hospital from 2011.9 to 2013.6.Controls: all the controls were selected randomly from community residents in Taixing city during the same period of time, according to the age and gender and ratio of 3:2.Univariate analysis and Logistic regression model was applied to analyze risk factors respectively.Results Seven hundred and seventy-seven stroke patients ( case group) and 518 controls ( control group) were brought into the study.It was preliminarily found in univariate analysis that compared with the control group, the rates of smoke, hypertension, diabetes, hyperlipidemia and the waist circumference, waist-to-hip ratio were significantly higher in the case group;while the total bilirubin level was significantly lower ( all P<0.001 ) .Logistic regression showed that smoking (OR=2.089, 95%CI:1.452-3.005), hypertension (OR=3.838, 95%CI:2.516-5.855) were risk factors of stroke in the elder population in Taixing, elevated total bilirubin level ( OR=0.281, 95%CI:0.155-0.508) was protective factor of stroke in the elder population ( all P<0.05 ).Conclusion No smoking, no hypertension history could make it less possible for stroke to occur, and total bilirubin level becomes protective factor of stroke.

Objective To investigate the impacts of mecobalamin on plasma inflammatory factors (plasma high-sensitivity C-reactive protein (Hs-CRP) and carotid artery plaques in patients with H type hypertension.Methods Forty-eight acute ischemic stroke patients who were diagnosed with H type hypertension in the People's Hospital of Taixing were collected,and they were randomly divided them into treatment group and control group,and 24 cases of each group.Patients in both groups were given conventional therapies,including treatment of anti platelet aggregation,plaque stability and reduced plaque treatment.While patients in the treatment group were given additional oral drug of mecobalamin,500 μg each time,three times a day,6 months in all.Each case was evaluated at the second day of hospitalization,four weeks later,eight weeks later,three months and sixth months later.The examination items involved included level of plasma homocysteine(Hcy),level of hsCRP and conditions of carotid artery plaques under ultrasonography.Results Aafter four weeks,eight weeks,three months and sixth months therapy,there were significant differences between treatment group and control group in terms of Hcy (t =4.049,3.896,6.052,6.159 ; P ＜ 0.05) and the level of hs-CRP (t =37.249,28.376,26.454,0.522P ＜ 0.01).Afrter three months and sixth months therapy,compared to the control group,the carotid artery plaques were obviously reduced,and the differences were statistically significant (t =2.309,2.434 ; P ＜ 0.05).Conclusion Mecobalamin can reduce the level of plasma homocysteine,then lead to reductions of levels of plasma inflammatory factors and volume of carotid artery plaques.
