摘    要:目的:观察血管紧张素Ⅱ受体拮抗剂缬沙坦治疗对原发性高血压(EH)合并糖耐量异常(IGT)人群血浆一氧化氮(NO)、内皮素(ET)及血浆炎症因子影响。方法:42例EH合并IGT患者口服缬沙坦80mg,1次/d,选择40例正常人作为正常对照组。检测治疗前后血糖,餐后2h血糖(2hPG),胰岛素抵抗指数(HOMA—IR),血清炎症因子和NO水平的变化。结果:与正常对照组比较,EH+IGT组血压、2hPG、HOMA—IR、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6),内皮素水平明显升高,NO水平明显降低(P〈0.01);与治疗前比较,缬沙坦治疗8周末血压[(163.95±8.0)/(99.10±11.8)mmHg比(132.93±10.7)/(82.14±9.5)mmHg]、2hPG[(9.10±1.10)mmol/L比(7.85±1.15)mmol/L]和HOMA-IR[(3.90±2.11)比(2.73±1.71)]、血浆ET[(47.84±7.79)ng/L比(31.84±4.5)ng/L]、TNF-α[(32.30±5.49)ng/L比(26.83±4.83)ng/L]和IL-6[(112.70±24.79)ng/L比(77.224-11.53)ng/L]水平显著下降,血浆NO显著上升[(38.1±7.36)μmol/L比(43.38±7.52)μmol/L],P均〈0.01。结论:缬沙坦可降低原发性高血压合并糖耐量异常患者血压、血糖、胰岛素抵抗、血浆内皮素、炎症因子水平,升高一氧化氮水平,改善血管内皮功能,抑制炎症反应。

Abstract:Objective: To study effects of angiotensin Ⅱ receptor blocker valsartan on plasma levels of nitric oxide (NO), endothelin (ET) and inflammatory factors in patients with essential hypertension (EH) complicated impaired glucose tolerance (IGT). Methods: A total of 42 EH + IGT patients were given valsartan 80 mg oral, once a day, and another 40 healthy adults were regard as normal control group. Detections were performed on blood glucose, 2h postprandial blood glucose (2hPG), homeostasis model-insulin resistance index (HOMA--IR), levels of NO and serum inflammatory factors in the two groups before and after treatment. Results: Compared with normal control group, levels of blood pressure, 2hPG, HOMA-- IR, tumor necrosis factor-α (TNF-α), interleukin- 6 (IL- 6) and ET significantly increased, and NO level significantly decreased in EH IGT group (P〈0.01) ; compared with before treatment, there were significant decrease in levels of blood pressure [ (163.95 ±8.0) / (99.10±11.8)mmHg vs. (132.93±10.7) / (82.14±9.5) mmHg], 2hPG [(9.10±1. 10) mmol/L vs. (7.85±1. 15) mmol/L], HO- MA-IR [(3.90±2.11) vs. (2.73 ±1.71)], plasma ET [ (47.84 ±7.79) ng/L vs. (31.84 ±4.5) ng/L], TNF-α[ (32.30±5.49) ng/L vs. (26.83±4.83) ng/L] and IL-6 [ (112.70 ±24.79) ng/L vs. (77.22±11.53) ng/L] and significant increase in plasma level of NO E (38.1|7.36) μmol/L vs. (43.38±7.52) μmol/L] in EH + IGT group after eight-week treatment with valsartan, P〈0.01 all. Conclusion: Valsartan can decrease blood pressure, bood glucose, insulin resistance index, plasma level of ET and inflammatory factors, increase level of NO, improve vascular endothelial function and inhibit inflammatory reactions.
