Objective To observe the polymorphism of nitric oxide synthase(NOS)gene and the changes of nitric oxide(NO)in cerebral infarct.Methods The prospective case-control study was employed.Cases contained 193 subjects with cerebral infarction of internal carotid artery system within 2 weeks.Controls contained 103 subjects which came from the normal health checkup.The polymorphism in intron 4 of endothelial nitric oxide synthase(eNOS)gene were detected.NO content was measured by Griess diazotization assay and NOS activity by enzynatic assay.Results There were 48 subjects with allele a in intron 4 of eNOS gene(eNOS4a)in cases and 12 in controls.The frequencies of eNOS4a in cases was higher than that in controls(χ2=8.86,P=0.003).Multivariate Logistic regression analysis confirmed that eNOS4a was an independent risk factors for cerebral infarction(P=0.032).NO production and NOS activity were 6.04(3.83～11.49)μmol/L,(2.97±1.47)U/ml,respectively in cases,and 6.89(4.64～12.43)μmol/L,(3.16±1.46)U/ml,respectively in controls.NO production in cases were significantly lower than that in controls(P=0.022).There was not differential in NOS activity between these two groups(P=0.517).NO production and NOS activity were 5.07(3.18～7.62)μmol/L,(2.77±1.13)U/ml,respectively in the subjects with eNOS4a,and 6.89(4.64～12.43)μmol/L,(3.12±1.54))U/ml,respectively in the subjects without eNOS4a.NO production in the subjects with eNOS4a were significantly lower than that in the subjects without eNOS4a(P=0.001).The NOS activities were not significantly different in subjects with or without eNOS4a(P=0.100).Conclusion eNOS4a possibly exerted some effects on cerebral infarction by diminishing NO.

Objective To study the effect of blood glucose fluctuations on the prognosis of thrombolytic therapy in patients with acute cerebral infarction. Methods A total of 83 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,General Hospital of Beijing Military Command ( the Affiliated 81st Brain Hospital ) from January to November 2013 were enrolled retrospectively. They were divided into cerebral infarction with type 2 diabetes mellitus group (DMCI group,n=47) and cerebral infarction without type 2 diabetes mellitus group (NDMCI group,n=36) according to whether they had diabetes mellitus or not and the results of oral glucose tolerance test at day 7 after admission. Continuous glucose monitoring system ( CGMS) was used to monitor glucose for 72 hours at day 7 after admission. The mean blood glucose, standard deviation of blood glucose level, mean blood glucose fluctuation,and hemorrhagic transformation during the follow-up period,as well as vascular recanalization were observed and compared. At day 90,the modified Rankin scale (mRS) score was used to evaluate the prognosis of the patients. Results ( 1 ) Comparing the dynamic glucose parameters of the patients with acute cerebral infarction in both groups,the mean blood glucose,standard deviation of blood glucose level,mean blood glucose fluctuations at 24 hours in patients of the DMCI group were higher than those of the NDMCI group ( 8 . 3 ± 2 . 6 mmol/L vs. 5 . 8 ± 1 . 3 mmol/L,2. 1 ± 0. 4 mmol/L vs. 1. 6 ± 0. 6 mmol/L,4. 3 ± 0. 8 mmol/L vs. 3. 6 ± 0. 5 mmol/L). There were significant differences (t=31. 419, 15.537,and 15. 372,respectively;all P<0. 01). (2) Four patients (8.5%) in the DMCI group had hemorrhagic transformation during the follow-up period,17 cases (36. 2%) had good recanalization,and 15 cases (31.9%) had good prognosis (the mRS score < 2 at day 90);1 patient (2.8%) in the NDMCI group had hemorrhagic transformation,21 patients (58. 3%) had good recanalization,and 21 cases (58. 3%) had good prognosis. There was significant difference between the recanalization after thrombolysis and the prognosis in patients of both groups (P<0. 05). Conclusion The great fluctuations of blood glucose in acute cerebral infarction patients with type 2 diabetes mellitus may be an important factor of affecting its prognosis of thrombolytic therapy.

Objective: To study the expression of PDCD5 mRNA and its significance in esophageal cancer in Xinjiang Kazakh and Han nationality. Methods: RT-PCR was used to detect the mRNA of PDCD5 in 40 cases of esophageal cancer (18 cases of Kazakh, 22 cases of Han). Results: The positive rate of PDCD5 mRNA expression in 40 samples of esopha-geal cancer tissue, adjacent tissue, and normal tissue was 80.0% (32/40), 80.0% (32/40) and 87.5% (35/40), respectively, with no significant difference (P>0.05). The Ods of cancer tissues, adjacent tissues, and normal tissues were 0.7644± 0.1444, 0.9341 ±0.1631 and 1.8703±0.4767, respectively. The expression of PDCD5 was significantly increased in cancer tissues compared with that in normal tissues (P<0.05). The expression level of PDCD5 mRNA was not significantly correlat-ed with the degree of differentiation and lymph node metastasis. Conclusion: No significant difference was found in PDCD5 mRNA expression in esophageal cancer between Xinjiang kazakh and Han nationality (P>0.05). The expression of PDCD5 is not correlated with the degree of differentiation, depth of invasion or lymph node metastasis. Detection of PDCD5 mRNA expression in esophageal cancer tissues may provide valuable information for patient prognosis.
