Objective To explore the clinical value of 3.0T nuclear magnetic resonance susceptibility weighted imaging in diagnosis of neonatal hypoxic ischemic encephalopathy,thus to provide guidance for the clinical.Methods From December 10,2015 to December 10,2017,100 cases of neonatal hypoxic ischemic encephalopathy (observation group) and 100 cases of normal newborns in Lishui People's Hospital during the same period accepted health examination (control group) were selected in the research.All the cases received 3.0T magnetic resonance susceptibility weighted imaging,the diagnostic value of 3.0T MR susceptibility weighted imaging was observed.Results The ADC value of the observation group[(0.00 1 13 ± 0.000 01)mm2/s] was significantly lower than that in the control group[(0.001 98 ±0.000 02)mm2/s] (P ＜0.05).The neonatal ADC value of the mild group[(0.001 21 ± 0.000 01)mm2/s] was significantly higher than that in the moderate group[(0.001 12 ± 0.000 02)mm2/s] and the severe group[(0.001 02 ± 0.000 03)mm2/s] (P ＜ 0.05).ADC value was positively correlated with neonatal hypoxic ischemic encephalopathy,namely,the lower the ADC value,the more serious the neonatal hypoxic ischemic encephalopathy.The fractional anisotropy value and relative anisotropy value of newborn babies in the observation group were significantly higher than those in the control group (all P ＜ 0.05).Conclusion For neonatal hypoxic ischemic encephalopathy patients,3.0T nuclear magnetic resonance susceptibility weighted imaging in the diagnosis is feasible,it can help the clinician to analyze the disease,and has positive significance to carry out the treatment.

Objective To investigate the association between acute myocardial infarction (AMI) and the (GT)n repeat sequence polymorphism in promoter region of heme oxygenase-1 (HO-1) , and to study the influence of serum bilirubin on AMI as well for HO-1 as a rate-limiting enzyme of bilirubin production in patients from Uighur national minority. Method Totally 287 patients with AMI evidenced by coronary arteriography admitted from January 2006 to June 2008 were eligible for being studied, and another 190 healthy subjects without anomaly in coronary arteriography, and with normal findings in physical examination and in variety of biochemical assays were enrolled as controls. Serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDL-C), serum bilirubin were detected. Polymerase chain reaction-nondenaturing polyacrylamide gel electrophoresis was used to detect HO-1 promoter (GT)n repeat polymorphism, and at the same time the serum bilirubin was determined. The group representation of samples was tested with HardyWeinberg balance test. Differences in distributions of genotypes and alleles between AMI patients and control subjects were analyzed using Chi-square test. Comprehensive evaluation of the factors associated with myocardial infarction using multi-factor Logistic regression analysis. P < 0.05 was considered as significantly different. Results Body mass index, triglyceride, high density lipoprotein cholesterol and the proportion with hypertension in myocardial infarction group was significantly higher than those in control group ( P < 0.01) . The X~2 values of HO-1genotype distribution in the myocardial infarction group and the control group were 2.09 and 0.05, respectively (P > 0.05), consist with the results of Hardy-Weinberg balance test. The HO-1 genotype was classified into three groups, L/L, L/S and S/S. The L/L genotype frequency (35.5%) and L-allele frequency (57.8%) in AMI group and in control group showed statistically significant differences, respectively (X~2 = 11.65, P = 0.001; X~2= 11.32, P = 0.003). The bilirubin level of L/L genotype significantly decreased compared with that of S/S, L/S genotype ( P all < 0. 001) . Logistic regression analysis showed that body mass index, high blood pressure,triglycerides, blood bilirubin and HO-1 gene polymorphism are risk factors of myocardial infarction. Conclusions To the Xinjiang Uighur ethics, HO-1 promoter ( GT) n repeat polymorphism and the occurrence of myocardial infarction are relevant. People with L allele genotype have lower serum bilirubin and higher risk of myocardial infarction.

Objective To investigate prevalence and risk factors of peripheral artery disease (PAD), metabolic syndrome (MS) and peripheral artery disease complicated with metabolic syndrome among Kazakh adults lived in Xinjiang Yili prefecture. Methods Four-stage cluster sampling method was used to select adults aged 35 years and over for the study from six cities and prefectures of Xinjiang. All the participants were interviewed with questionnaire to collect their demographic characteristics. Physical checksup and blood biochemical measurements were performed for all of them, as well as blood pressure was measured in their lower legs and arms to calculate ankle brachial pressure index ( ABPI), a ratio of the blood pressure in the lower legs to that in the arms. Only data of Kazakh adults in Yili prefecture were analyzed in this paper, including prevalence and risk factors for PAD and MS, as well as their relationship.The patients with PAD were divided into two groups, one complicated with MS and the other without it Logistic regression analysis was used to identify potential risk factors for PAD and MS and their combination.Results A total of 1365 adult Kazakh people were surveyed. Prevalence of MS was 23.7 percent, 30.4 percent for men and 19.0 percent for women, respectively, and that of PAD was 9. 4 percent, 7.0 percent for men and 11.0 percent for women, respectively. Mean age in patients of PAD complicated with MS was older than that in those without MS (t=-5.348, P＜0.01). Risk of PAD complicated with MS in Kazakh people associated with gender ( men), age, systolic pressure, diastolic pressure and blood glucose level.(P＜0.05). Conclusions Both prevalence of PAD and MS are significantly higher among Kazakh people in Yili prefecture of Xinjiang, and increase with age. Prevalence of PAD is significantly higher in those with MS than that in those without MS. Risk factors of PAD complicated with MS include gender(men), age,systolic pressure, diastolic pressure and blood glucose level.

Objective To investigate the association between matrix metalloproteinase-9 (MMP-9) gene polymorphism (-1562C ＞ T/R279Q) and acute coronary syndrome (ACS) in Uygur nationality of Xinjiang Autonomous Region of China. Methods A total of 352 patients with ACS including 213 patients with unstable angina pectoris and 139 patients with acute myocardial infarction evidenced by using coronary arteriography and 421 control subjects were recruited in this study. The MMP-9-1562C ＞ T and R279Q genotypes were detemined by using PCR-RFLP method. The relationship between the polymorphism in the MMP-9 gene and the severity of coronary arterial stenosis was analyzed. All polymorphisms were determined for confimation with Hardy-Weinberg expectations in both groups separately. Differences in distributions of genotypes and alleles between two groups were analyzed with x2 test. The association between the MMP-9 polymorphisms and the risk of ACS was estimated by odds ratio(Ors) and their 95% confidence intervals (CIs), and the comprehensive evaluation of the factors associated with ACS was determined by using multifactor logistic regression. P ＜ 0. 05 was considered to be statistically significant. Results The genotype frequencies for CT + TT genotypes and T allele were 25.9 and14.5 percent in ACS subjects and 15.7 and 8.4 percent in control subjects, respectively. The genotype frequencies were different significantly between the two groups (x2 = 12.26,P ＜ 0.01;x2 = 14.15,P ＜ 0.01, respectively). No relationship between R279Q polymorphism and ACS was found in this study ( P ＞ 0.05). The multifactor logistic regression analysis showed that the T allele carrier (CT + TT) significantly increased the risk of ACS compared with the CC genotype ( OR = 1.791,95 % CI: 1. 088 - 2.951, P = 0.022) after adjustment for tradition risk factors. The frequencies for CT + TT and CC genotypes of the -1562C ＞ T polymorphism were not statistically different among ACS patients with one, two and three or more significantly diseased vessels ( x2 = 1.15, P = 0.56). Conclusions The findings suggest that the polymorphism in MMP-9 gene promoter (-1562C ＞ T) is associated with the susceptibility to the ACS. The T allele might be an independent risk factor for the ACS. But the -1562C ＞ T polymorphism may not be useful as a predictor of the severity of coronary arterial stenosis. The R279Q polymorphism of MMP-9 gene was not significantly associated with ACS in this studied population.
