摘  要:目的分析围绝经期妇女不同阶段血清抑制素B(inhibin B,INHB)水平的变化及其临床意义。方法选择2010年3月至2012年7月黄浦区中心医院妇科门诊患者及健康普查妇女118例,年龄45~53岁,按月经周期分4组:对照组30例,月经周期规则;围绝经早期组30例,闭经3~6个月;围绝经晚期组28例,闭经7~12个月;绝经后期组30例,闭经13~36个月。分别用酶联免疫吸附试验检测血清INHB,放射免疫法检测血清雌二醇(estradiol,E2)、促卵泡素(follicle-stimulating hormone,FSH)水平,分析各组激素水平变化之间的关系。结果与对照组相比,INHB于围绝经早期就明显下降(t=2.79,P〈0.01),但FSH、E2于围绝经早期无明显变化(P﹥0.05);而FSH明显上升(t=7.67,P〈0.001)与E2的明显下降(t=6.43,P〈0.001)都发生在围绝经晚期,而此阶段INHB也有进一步下降但差异无统计学意义(P﹥0.05)。绝经后期与围绝经晚期比较INHB进一步下降(t=2.68,P〈0.01)、FSH进一步上升(t=3.41,P〈0.01)、E2进一步下降(t=3.39,P〈0.01)。研究还显示,INHB的变化与FSH呈负相关(r=-0.423,P〈0.01)、与E2呈正相关(r=0.407,P〈0.01)。结论血清INHB的下降是围绝经期最早变化的生化指标,可预判卵巢功能衰退和围绝经期起点。Objective To investigate changes of serum inhibin B( INHB) levels in different perimenopausal stages and its clinical significance. Methods One hundred and eighteen w omen aged 45 ~ 53,w ho visited gynecology clinic for consultation or health check from March 2010 to July 2012, w ere enrolled in the study. All subjects w ere divided into four groups according to the menstrual cycle: control group( n = 30) w ith regular menstrual cycles,early perimenopausal group( n = 30),late perimenopausal group( n = 28) and postmenopausal group( n = 30). Serum inhibin( INHB) levels were detected by enzyme-linked immunosorbent assay( ELISA); serum estradiol( E2) and folliclestimulating hormone( FSH) levels w ere detected by radioimmunoassay. Results Compared to controls,INHBlevels in early perimenopause w ere decreased( t = 2. 79,P < 0. 01),but no significant changes in serum FSH and E2( P >0. 05). A significant increase in FSH( t = 7. 67,P < 0. 001) and decline in E2( t = 6. 43,P < 0. 001) were detected in late perimenopause,while INHBpresented a tendency of decline but not significantly. Compared to late perimenopause, INHBlevels in postmenopause w ere declined( t = 2. 68,P < 0. 01),FSH further increased( t = 3. 41,P < 0. 01) and E2further declined( t = 3. 39,P < 0. 01). The INHBchanges w ere negatively correlated w ith FSH levels( r =- 0. 423,P < 0. 01) and positively correlated w ith E2levels( r = 0. 407,P < 0. 01). Conclusion Serum INHBlevel in perimenopausal w omen may be used as a biochemical marker for predicting ovarian failure and menopause.
