摘　　要：目的利用促性腺激素释放激素类似物(曲普瑞林)兴奋试验评价多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者的下丘脑-垂体-性腺轴功能并探讨其变化特点。方法对PCOS患者(n=20)和健康对照者(n=30)进行曲普瑞林兴奋试验,在0、15、30、45、60和90 min测定血黄体生成素(luteinizing hormone,LH)和卵泡刺激素(follicular stimulating hormone,FSH)的水平。比较PCOS组和健康对照组在基线状态以及兴奋试验后LH、FSH水平的变化以及LH/FSH比值的差异。结果对照组和PCOS组患者的睾酮分别为(1.9±0.5)nmol/L和(3.5±1.4)nmol/L(P=0.012)。PCOS患者的基线LH水平高于对照组[(11.3±6.6)U/L比(3.7±2.7)U/L,P=0.028];在曲普瑞林兴奋试验中,PCOS组LH的升高幅度明显大于对照组;在第15分钟,PCOS组和对照组的LH分别为(41.4±28.0)和(24.7±19.0)U/L(P=0.036);在第60分钟,PCOS组和对照组的LH分别为(64.0±34.8)和(44.8±22.5)U/L(P=0.060)。PCOS组和对照组的基线FSH水平分别为(4.6±2.0)和(4.9±1.6)U/L(P=0.467);在曲普瑞林兴奋试验中,PCOS组FSH水平升高幅度小于对照组;在第60分钟,两组FSH水平分别为(9.9±4.0)和(17.3±5.6)U/L(P=0.041)。基线状态PCOS组和对照组的LH/FSH比值分别为2.9±1.1和0.8±0.2(P=0.023);此比值在曲普瑞林兴奋试验中进一步升高,在第60分钟时两组分别为6.5±1.3和3.1±0.9(P=0.038)。结论 PCOS患者基础状态LH和LH/FSH比值明显升高,在曲普瑞林兴奋试验中,LH和FSH曲线之间的差距进一步增加,LH/FSH比值进一步升高,提示PCOS患者存在特征性的下丘脑-垂体-卵巢轴功能异常。Objective To evaluate the function of hypothalamus-pituitary-gonad axis （ HPGA） in patients with polycystic ovary syndrome （ PCOS ） using gonadotropin-releasing hormone （ GnRH ） analogue （ triptorelin ） stimulation test and to investigate the changes of HPGA following triptorelin stimulation test. Methods Triptorelin stimulation test was conducted in PCOS patients （ n=20 ） and healthy controls （ n=30 ） . Serum levels of luteini-zing hormone （LH） and follicular stimulating hormone （FSH） were measured at 0, 15, 30, 45, 60 and 90 mi-nutes after intramuscular injection of triptorelin 100 μg in the test. LH and FSH levels and LH/FSH at baseline and after stimulation test were compared between the two groups. Results The control group had a higher level of testosterone than the PCOS group [ （1. 9 ± 0. 5） nmol/L vs. （3. 5 ± 1. 4） nmol/L, P=0. 012]. Baseline LH in the PCOS group was higher than that in the control group [（11. 3 ± 6. 6） U/L vs. （3. 7 ± 2. 7） U/L, P=0. 028]. After triptorelin stimulation test, LH in the PCOS group increased with a larger magnitude than the control group [at 15 min, （41. 4 ± 28. 0） U/L vs. （24. 7 ± 19. 0） U/L, P=0. 036;at 60 min, （64. 0 ± 34. 8） U/L vs. （44. 8 ± 22. 5） U/L, P=0. 060]. Baseline FSH in the PCOS group and the control group were （4. 6 ± 2. 0） and （4. 9 ± 1. 6） U/L （P=0. 467）, respectively. FSH increased less in the PCOS group than in the control group [at 60 min, （9. 9 ± 4. 0） U/L vs. （17. 3 ± 5. 6） U/L, P=0. 041]. Baseline LH/FSH ratios in the PCOS group and the control group were 2. 9 ± 1. 1 and 0. 8 ± 0. 2 （P=0. 023）, respectively, which both increased after trip-torelin stimulation test （6. 5 ± 1. 3 vs. 3. 1 ± 0. 9, P=0. 038）. Conclusions PCOS patients demonstrate higher baseline LH and LH/FSH ratio, growing difference between LH and FSH levels and increasing LH/FSH ratio af-ter triptorelin stimulation test, which indicate dysfunction of HPGA in PCOS patients.
