Objective : To study plasma N terminal pro brain natriuretic peptide (NT-proBNP ) level difference be-tween Han nationality and Uighur nationality patients with acute coronary syndrome (ACS) in Xinjiang .Methods : A total of 482 Uygur and Han nationalities ACS patients (uighur : 212 cases , han : 270 cases) hospitalized from May 2012 to Aug 2013 were selected . According to ACS types , they were divided into unstable angina pectoris (UAP) group (n = 234) ,acute ST segment elevation myocardial infarction (STEMI) group (n = 166) and acute non- ST segment elevation myocardial infarction (NSTEMI) group (n = 82) .All patients received coronary angiography (CAG) and their NT-proBNP levels were compared .Results : ① CAG results indicated that Uygur nationality ACS patients were mainly multi-vessel coronary disease and the percentage was significantly higher than that of Han na - tionality ACS patients (61.32% vs .40.00% ) ; ② Compared with Han nationality ACS patients ,there were significant rise in NT-proBNP levels [UAP : 168.5 (70.6 ~ 272.5) pg/ml vs .383.2 (210.3 ~ 739.5 ) pg/ml ,STEMI : 618.5 (231.7 ~ 1387) pg/ml vs .1209.5 (908 ~ 3214) pg/ml ,NSTEMI : 446.7 (252.21 ~ 831.92) pg/ml vs .1066 (928 ~ 3448.25) pg/ml] in Uygur nationality ACS patients ; ③ Compared with Han nationality ACS patients ,there were significant rise in NT-proBNP levels [Single vessel : 221.7 (20 ~ 2851) pg/ml vs .557.1 (125 ~ 1956.2) pg/ ml ,double-vessel : 421.2 (75.2 ~ 3401.5) pg/ml vs .610.5 (174.4 ~ 5679.1) pg/ml ,multi-vessel : 648.2 (142.4 ~ 3850) pg/ml vs .812.3 (154.8 ~ 6832.5) pg/ml] in Uygur nationality patients with different number of diseased coronary vessels , P < 0.05 ~ < 0.01 .Conclusion : NT-proBNP level in Uygur nationality ACS patients is significant - ly higher than that of Han nationality patients ,it may be related with hereditas ,living habit ,risk factor control , early diagnosis and treatment of disease ,post-discharge compliance of treatment ,which possesses important value for assessing patient′s condition .

Objective This study investigated the relation with the location of infarction and brain natriuretic peptide (BNP),left ventricular ejection fraction (LVEF) for first acute ST-segment elevation myocardial infarction.Methods From January 2014 to December 2016,163 consecutive patients with ASTEMI who admitted to our hospital were enrolled in this study,were divided by infarction position.All the patients were classified into wide anterior infarction group,anterior infarction group,anterior septal infarction group and inferior infarction group.The BNP level and the LVEF were measured for 163 consecutive patients respectively on admission and after six-month follow-up visit and record the adverse cardiovascular events,comparing their relations.Results The BNP level of wide anterior infarction group were all significantly higher than all the other groups on admission and after six-month follow-up visit,but the LVEF were significantly lower than all the other groups (P ＜ 0.05).The BNP level of anterior infarction group were significantly higher than anterior septal infarction group and inferior infarction group on admission and after six-month follow-up visit,but the LVEF were significantly lower than anterior septal infarction group and inferior infarction group (P ＜ 0.05).The BNP level of anterior septal infarction group were higher than inferior infarction group on admission and after six-month follow-up visit,but the LVEF were lower than inferior infarction group (P ＜ 0.05).Meanwhile,the incidence of adverse cardiovascular events of the wide anterior infarction group,anterior infarction group,anterior septal infarction group were all larger than inferior infarction group,and the wide anterior infarction group was the largest.Conclusion There is a close relationship with infarction position,BNP and LVEF.The location of infarction,BNP level and LVEF counld all be recognized as the important predicted indicator of adverse cardiovascular events,premature complication and prognosis.

Objective:To investigate the relationship between microRNA (miR)-1, miR-133b and hepatic fibrosis in patients with hepatic alveolar echinococcosis.Methods:From October 2020 to April 2021, patients who were definitely diagnosed as hepatic alveolar echinococcosis (9 cases), cirrhosis (9 cases) and hepatocellular carcinoma (5 cases) in the First Affiliated Hospital of Xinjiang Medical University were selected as the research subjects, and healthy volunteers in the same period were taken as the control (10 cases). Peripheral blood samples of all subjects were collected to prepare plasma, and the expression levels of miR-1 and miR-133b in peripheral blood were detected by quantitative real-time PCR. At the same time, tissue samples around the liver lesion (proximal), and the corresponding tissues about 5 cm from the lesion (distal) were collected from 5 patients with hepatic alveolar echinococcosis, and immunohistochemical staining was used to detect the cell activation related indicators [cyclinD1, cyclin dependent kinase 1 (CDK1), α-smooth muscle actin (α-SMA)], fibrosis indicators (Collagen Ⅰ, Collagen Ⅲ), transforming growth factor-β1 (TGF-β1) signal pathway related genes [TGF-β1, TGF-β1 receptor type Ⅰ/Ⅱ (TGF-β1RⅠ, TGF-β1RⅡ)] and its downstream related proteins (SMAD2, SMAD3).Results:The quantitative real-time PCR results showed that there were significant differences in the expression levels of miR-1 and miR-133b in the peripheral blood of patients with hepatic alveolar echinococcosis, cirrhosis, hepatocellular carcinoma and the control group ( H = 16.54, 28.40, P < 0.001); the expression levels of miR-1 and miR-133b in hepatic alveolar echinococcosis group were higher than those in control group, cirrhosis group ( P < 0.05). The expression levels of CDK1 (0.46 ± 0.02, 0.42 ± 0.01), α-SMA (0.54 ± 0.09, 0.51 ± 0.07), TGF-β1 (0.55 ± 0.15, 0.51 ± 0.13), TGF-β1RⅠ (0.58 ± 0.09, 0.57 ± 0.08), and TGF-β1RⅡ(0.40 ± 0.05, 0.39 ± 0.05) between the proximal and distal tissue of liver lesion in hepatic alveolar echinococcosis patients were statistically significantly different ( t = 5.56, 3.17, 3.18, 4.27, 5.65, P = 0.005, 0.034, 0.034, 0.024, 0.011). There was no statistically significant difference in the expression levels of CyclinD1, Collagen Ⅰ, Collagen Ⅲ, SMAD2 and SMAD3 between the proximal and distal tissue of liver lesion in hepatic alveolar echinococcosis patients ( t = 3.06, 3.06, 2.86, 1.43, 1.50, P = 0.055, 0.055, 0.064, 0.247, 0.230). Pearson correlation analysis showed that miR-1 in the patients' peripheral blood was positively correlated with TGF-β1RⅠ in the proximal tissue of the liver lesion ( P = 0.001); there was no correlation between miR-1, miR-133b and CDK1, α-SMA, TGF-β1, TGF-β1RⅡ( P > 0.05). Conclusions:The expression of TGF-β1 signaling pathway related factors in the proximal tissue of liver lesion in patients with hepatic alveolar echinococcosis is up-regulated. The expression of miR-1 and miR-133b in peripheral blood is upregulated, and miR-1 is positively correlated with TGF-β1RⅠ level in proximal tissue of liver lesion, suggesting that miR-1 may promote the occurrence of liver fibrosis in hepatic alveolar echinococcosis.
