摘　　要：目的分别比较青春期多囊卵巢综合征(PCOS)与青春期健康人群、青春期PCOS胰岛素抵抗(IR)与非IR患者的生殖内分泌指标,认识青春期PCOS的IR及其与生殖内分泌代谢异常的相关性,为该疾病的早期诊断和治疗提供循证医学依据。方法青春期PCOS患者(青春期PCOS组)88例,青春期健康对照人群(对照组)87例,并根据胰岛素抵抗稳态模型指数(HOMA-IR)将青春期PCOS患者分为IR组(40例)和非IR组(48例)。测定LH、FSH、硫酸脱氢表雄酮(DHEAS)、性激素结合蛋白(SHBG)、总睾酮(TT)、FBG、空腹胰岛素(FINS)、瘦素(LEP)和脂联素(ADPN)水平,并加以对照研究。结果(1)青春期PCOS组与对照组的比较:青春期PCOS组LH、LH/FSH、DHEAS、TT、FAI、FINS、HOMA-IR、LEP均明显高于对照组,SHBG明显低于对照组,两组间FBG、ADPN未见有统计学差异。(2)青春期PCOS IR组与非IR组的比较:IR组LH明显低于非IR组,而DHEAS、FAI均明显高于非IR组,两组间LH/FSH、TT无统计学差异。IR组SHBG明显低于非IR组,且SHBG与BMI(r=-0.31,P<0.05)、血DHEAS(r=-0.225,P<0.05)均呈明显负相关。IR组FINS、FBG、HOMA-IR均明显高于非IR组,且FBG与BMI呈明显正相关(r=0.348,P<0.05)。IR组LEP水平明显高于非IR组,而ADPN明显低于非IR组,且LEP水平与BMI呈明显正相关(r=0.605,P<0.05),ADPN水平与BMI呈明显负相关(r=-0.418,P<0.05)。结论 PCOS在青春期即出现不同程度的胰岛素敏感性下降,IR发病率增高,并与高雄激素血症、肥胖相互作用,形成内分泌代谢的恶性循环,促进PCOS疾病进展,使得代谢综合征等远期并发症风险增高。脂肪因子ADPN和LEP或可成为机体胰岛素敏感性的预测指标,但还需进一步大样本研究。Objective To investigate the endocrinal abnormalities of adolescent polycystic ovary syndrome（PCOS） with or without insulin resistance （IR）. Methods Eighty eight adolescent patients with polycystic ovary syndrome（PCOS group）, includ-ing 40 cases with IR and 48 cases without IR, and 87 healthy women （control group） were enrol ed in the study. The serum en-docrine levels were measured and their relationships with homeostasis model of assessment for insulin resistance （HOMA- IR ） were analyzed. Results Compared to control group, PCOS group had a higher levels of 1uteinizing hormone （LH）, luteinizing hormone/follicle stimulating hormone ratio（LH/FSH ratio）, dehydroepiandrosterone sulfate（DHEAS）, total testosterone（TT） and free androgen index （FAI）, but a lower level of the sex hormone binding globulin （SHBG）. There was a significant difference in serum fasting insulin （FINS） and HOMA- IR levels, but no difference in serum fasting bloodglucose （FBG） between adolescent PCOS and control groups. The adolescent PCOS group had a higher level of leptin, but there was no difference in adiponectin level be-tween two groups. The DHEAS and FAI levels in IR group of PCOS patients were higher, while SHBG and LH levels were lower than those in non- IR group. The serum SHBG level was negatively correlated with BMI（r=- 0.31, P〈0.05） and serum DHEAS level （r=- 0.225, P〈0.05） in adolescent patients with PCOS. There were no significant differences in TT and LH/FSH ratio between two groups. The IR group had a higher levels of FINS, FBG and HOMA- IR. The FBG level was positively correlated with BMI （r=- 0.348, P〈0.05）. The leptin level was significantly higher and adiponectin level was lower in IR group than those in non- IR group. The adiponectin level was negatively correlated with BMI（r=- 0.418, P〈0.05）;while the leptin level was positively correlated with BMI （r=0.605, P〉0.05）. Conclusion The PCOS patients have decreased insulin sensitivity with various
