针刺影响单纯肥胖病患者血浆酪酪肽水平观察

目的:观察钎刺减肥过程中血浆酪酪肽(PYY)的变化,以了解其与减肥效应的关系.方法:临床针刺治疗34例单纯性肥胖病患者3个疗程,治疗前后测量体质指数(BMI)、脂肪百分率(F%),酶联免疫法测定血清胰岛素,放免法测定血浆PYY,生化比色法测定血脂、血糖,并与20例正常人对照.结果:临床总有效率88.23%,针刺可提高患者降低的胰岛素敏感指数(IAI,t=-5.103,P=0.000)和PYY水平(t=-4.195,P=0.000),但变化的相关性未达到显著性水平(r=0.058,P=0.745).结论:调节PYY可能是针刺减肥取得疗效的途径之一,但其与改善肥胖机体的脂肪代谢异常引起的胰岛素抵抗性的关系有待进一步研究.

Effect of acupuncture on plasma peptide YY in the patient of simple obesity

Objective To observe changes of plasma peptide YY (PYY) in acupuncture for slimming. Methods Thirty-four cases of simple obesity were treated with acupuncture for 3 courses. Body mass index (BMI), and fat percent (F%), and insulin, PYY, blood fat, and blood sugar levels before and after treatment were determined, with 20 normal persons used as controls. Results The clinical total effective rate was 88.23%. Acupuncture could increase the decreased insulin sensitive index and PYY level (both P<0.01), with no correlativity between them(P>0.05). Conclusion Regulation of PYY is possibly one of the mechanisms of acupuncture in slimming, but the relation of PPY with insulin resistance remains to be studied.
