Objective To evaluate 64-MSCT virtual endoscopy in the examination method,displaying ability and clinical application of colon lesions.Methods Compared the results of 49 cases of patients examined with 64-MSCT with that got from Coloscopy,and statistical analysis was conducted.Results A total of 19 cases of adenocarcinoma and 2 cases of colonic diverticula as well as 44 cases of adenomatous polyp were detected.The display rate of polyps was 100％ in which was larger than 10mm,73％ in which was range of 5 ～ 10mm in size and 50％ in which was smaller than 5mm.Conclusion As an relatively noninvasive examination method,64-MSCT virtual endoscopy is concordant with onventional colonoscopy in the aspect of detectable rate and revealing the lesion morphologic and can be used as an important examination measure in the diagnosis for colonic diseases.

Objective To investigate the relationship between plasma homocysteine on admission and the outcome at discharge of acute ischemic stroke.Methods A non-concurrent cohort study was performed and a total of 1 3 1 9 patients with acute is-chemic stroke were continuously included in this study.According to tertile range of plasma homocysteine,patients were di-vided into three group.Logistic regression analysis was used to assess the independent association between plasma homocys-teine on admission and poor outcome at discharge of acute ischemic stroke.Results The difference of plasma homocysteine on admission between the poor outcome and those with good outcome had statistical significance (P<0.000 1).Without the adj ustment of multiple factors,when comparing to the first group,the second and third tertile seemed to have a tendency of increasing the risk of poor outcome at discharge,the OR (95%CI)was 2.111 (1.297~3.437,P<0.05),2.113 (1.361~3.279,P<0.05).After adjustment for multivariate,the second and third tertile also seemed to have a tendency of increasing the risk of poor outcome at discharge,the OR (95%CI)was 1.876 (1.160~3.036,P<0.05),2.396 (1.414~4.062,P<0.05).Conclusion The current study indicated that higher plasma homocysteine level was an independent risk factor for poor outcome at discharge in ischemic stroke patients.It would increase the risk of the outcome at discharge in patients with acute ischemic stroke,and suggests that there is a dose-response relationship between plasma homocysteine level on admis-sion and the poor outcome at discharge.
