In this study, the effect of prophylactic anti-inflammation on the development of smoke-induced emphysema was investigated. Young male guinea-pigs aged 1.5-2 months (weighing 198.3+/-26.9 g) were randomly divided into 4 groups: group A (cigarette smoke exposure only), group B (cigarette smoke exposure plus pentoxifylline-rich (PTX, 10 mg/d) forage feeding), group C (cigarette smoke exposure plus intermittent cortical steroid injection (Triamcinolone acetonide, 3 mg, i.m., every three weeks) and control group (group D: animals with sham smoke exposure, raised under the same conditions). Animals in group A, B and C were exposed to smoke of cigarettes for 1 to 1.5 h twice a day, 5 days a week. All animals were killed at the 16th week and followed by morphometrical analysis of the midsagittal sectioned lung slices. Smoke exposure of 16 weeks resulted in visible emphysematous development in Group A but not in Group B and C. It was evidenced by the indicator of air-space size, mean linear intercept (Lm): 120.6+/-16.0 microm in Group A; 89.8+/-9.2 microm in Group B and 102.4+/-17.7 microm in Group C. The average Lm in either group B or group C was shorter than that in Group A (ANOVA and Newman-Keuls test, F=8.80, P=0.0002) but comparable to that (94.8+/-13.2 microm) in group D (P>0.05). It is concluded that long-term prophylactic anti-inflammation inhibits pulmonary emphysema induced by cigarette smoking in the guinea pigs.

OBJECTIVETo discuss the changes in Wnt pathway inhibiting factors in esophageal precancerosis lesions induced by methyl benzyl nitrosamine (MBNA) and the effect of Gexia Zhuyu decoction.

METHODWistar rats were subcutaneously injected with MBNA (3.5 mg x kg(-1) for twice per week to establish the model. Since the 1st day after the model establishment, they were orally administered with Gexia Zhuyu decoction (16, 8 mg x kg(-1)). At the 10th week, esophageal tissues were collected to observe the pathological changes of esophageal mucosa, detect SFRP1, sFRP4, Axin1, Axin2 and GSK-3β mRNA levels.by fluorescent quantitation PCR analysis and β-catenin protein level by Western blotting.

RESULTBeing induced by MBNA, rats in the model group showed slight atypical hyperplasia in the histopathological examination. Compared with the normal group, Gexia Zhuyu decoction dose high and low groups showed no significant pathomorphological and histological changes. The model group showed lower gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and higher β-catenin protein expression level (P < 0.01) than the normal control group. The Gexia Zhuyu decoction low dose group showed higher gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and lower β-catenin protein expression level (P < 0.01) than the normal control group.

CONCLUSIONUp-regulated β-catenin protein level and down-regulated Wnt pathway could enhance Wnt pathway activity of MBNA-induced esophageal precancerous lesions. Gexia Zhuyu decoction could down-regulate the β-catenin protein level and up-regulate the transcription level of Wnt pathway inhibiting factors, but could not block MBNA-induced esophageal precancerosis lesions.

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.

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 study the association between serum concentrations of total testosterone levels and coronary heart disease (CHD) in the postmenopausal women. Methods The study was designed as a case-control study.394 postmenopausal female patients were selected from Cardiology Center of the First Affiliated Hospital of Xinjiang Medical University.The case group included 183 women patients with CHD aged (62.7±8.0) years,the control group,211 women with normal coronary aged (60.0 ± 8.8) years. Blood samples were collected to determine total testosterone,fasting glucose and lipid profile. CHD severity was expressed as the numbers of coronary arteries that had a stenosis ≥50％.According to the level of testosteron,all cases were divided into 4 groups by interquartile range method:Q1＜3.5 nmol/L(n=190),3.5 nmol/L≤Q2 ＜10.4 nmol/L(n=64),10.4 nmol/L≤Q3 ＜26.0 nmol/L(n=120) and Q4≥26.0 nmol/L(n=20).The association between the serum total testosterone levels and severity of coronary atherosclerosis was analyzed. Results The average total testosterone was higher in case group than in control group[(10.4 ± 24.3 ) nmol/L vs. ( 6.9 ± 17.4 ) nmol/L,Z =0.79,P =0.555].In Quantitative adjusted models,higher levels of total testosterone had strong correlation with CHD,Q4 incidence of CHD (75.0％,15 cases) was significantly higher than Q1 (46.8％,89 cases),Q2 (40.6％,26 cases)and Q3 (44.2％,53 cases) (x2 =7.69,P=0.048).After adjustment for other risk factors,women in the top quartile of total testosterone levels had a more than 3-fold increase in odds of CHD(OR=3.47,95％CI:1.06-11.32,P＜0.05).In addition,the serum concentrations of total testosterone level were significantly associated with the severity of CHD (F=12.94,P＜0.05). Conclusions Higher levels of total testosterone may be associated with high prevalence and severity of CHD as an independent factor in postmenopausal women.
