Effect of shexiang baoxin pill on the function of vascular endothelium in patients with diabetes mellitus type 2 complicated with angina pectoris / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of Shexiang Baoxin pill (SBP) on the vascular endothelial function in patients with diabetes mellitus type 2 (DM2) complicated with angina pectoris.</p><p><b>METHODS</b>Two weeks after runin, according to the randomizing table, 111 patients were divided into two groups, the XBP group (56 patients) and the control group (55 patients, treated with delayed-released isosorbide mononitrate, DRIM), they were treated for 6 months. In the treatment period, the episodes of angina attack and condition of rescue medication were recorded in the daily card, and brachial arterial changes of endothelium-dependent relaxing function before and after treatment were measured by B-ultrasonography.</p><p><b>RESULTS</b>Comparison between the two groups in episodes of angina attack and rescue medication were insignificantly different. In the control group, the basal value of brachial arterial inner diameter before and after treatment was 3.68 +/- 0.56 mm and 3.70 +/- 0.58 mm respectively, those before and after responsive congestion was 5.44 +/- 0.81% vs 5.68 +/- 0.83%, and those before and after taking nitroglycerin was 19.8 +/- 4.9% vs 20. +/- 5.2%, all showed insignificant difference (P > 0.05). In the SBP group, the corresponding basal value was 3.73 +/- 0.62 mm vs 3.71 +/- 0.59 mm, and those after taking nitroglycerin 18.8 +/- 4.5 % vs 19.2 +/- 5.8%, also showed insignificant difference, but those before and after responsive congestion (5.69 +/- 0.79 % vs 9.56 +/- 3.82 %) did show significant difference (P < 0.01).</p><p><b>CONCLUSION</b>XBP could improve the vascular endothelial function in patients with DM2 complicated with angina pectoris.</p>
