【摘要】 目的 了解不孕妇女月经周期中β-内啡肽(β-EP)变化规律及其与生殖激素的关系,探讨不孕患者精神心理状况、体内β-内啡肽水平与生殖的相互关系。方法 对19例不孕妇女进行心理状况评分,测定月经周期中不同时间β-内啡肽及生殖激素水平,同时进行排卵监测。结果 (1)不孕组β-EP水平卵泡中期最低、围排卵期稍高、黄体中期显著升高,周期中呈上升趋势,并明显高于同龄妇女(P<0.05)。(2)不孕组黄体中期LH、E 2 、P显著降低,T显著升高(P<0.05);周期中PRL水平均显著升高(P<0.01)。(3)卵泡中期β-EP与FSH、LH呈显著负相关,与E 2 呈显著正相关(P<0.01);围排卵期β-EP与LH呈显著负相关(P<0.05),与PRL呈显著正相关(P<0.01);黄体中期β-EP与PRL、P呈显著正相关(P<0.01)。(4)不孕组β-EP水平与心理状况评分呈显著正相关(P<0.001)。结论 (1)正常及不孕妇女月经周期中血浆中β-EP的变化与生殖周期密切相关。(2)不孕妇女β-EP水平显著升高,是不孕的发生、发展中起一定作用。(3)不孕妇女β-EP水平显著升高并与心理状况评分呈显著正相关,提示心理治疗在不孕夫妇咨询和综合治疗中起着不可忽视的作用。

【Abstract】 Objective To find out the regular change ofβ-EP and reproductive hormones in menstrual cycle and the correlation betweenβ-EP and psychological factors in infertile women.Methods 21cases of infertilitywomˉen,the psychological state were scored,theβ-endophin and other reproductive hormones at different phases were measured,and the ovulation monitored simultraneously.Results(1)The plasma level ofβ-EP in infertile group and control were lowest in mid-follicular phase,elevated a little in periovulatory phase and raised significantly in mid-luteal phase(P<0.05),displaying a ascending trend in cycles.In infertile group plasmaβ-EP were significantly higher in three phases compared with control group(P<0.05,respectively).(2)In three phases,serum LH,E 2 and Pwere significantly lower,serum Twas significantly higher than control group(P<0.05,respectivelty).The serum PRL levels of infertile group were significantly higher than control group in three phases(P<0.001,respectively).(3)In infertile group there were significant negative correlation between plasmaβ-EP andserum FSH as well as LH(P<0.01)and significant positive correlation between plasmaβ-EP and serum E 2 (P<0.05)in mid-follicular phase was observed.There were significant negative correlation between plasmaβ-EP and serum LH(P<0.05)and signifˉicant positive correlation between plasmaβ-EP and serum PRL(P<0.05)in periovulatory phase.Significant posiˉtive correlation between plasmaβ-EP and psychological score in infertile group.Conclusion (1)In normal and inˉfertile women the levels of plasmaβ-EP appeare to be regular periodic change in menstrual cycles,the change of it is closely related to menstrual cycle.(2)The plasmaβ-EP levels of the infertile group are significantly higher than conˉtrols.The significant negative correlation between plasmaβ-EP and gonadotropins in mid-follicular phase and periˉovulatory phase and significant positive correlation betweenβ-EP and PRL imply thatβ-EP may play a certain role in pathogenesis and development of infertility.(3)The plasmaβ-EP levels of the infertile groupare significantly highˉer and have a positive correlation with psychological score suggest that psycholgocial stress may induce the high level ofβ-EP which affects the reproductive function to some extent.It give a hint that psychotherapy plays an unneglected role in infertile consulation and combined treatment.

 随着生殖内分泌学科及辅助生殖技术的发展,不孕症的诊断、治疗技术有了很大提高,精神心理因素在不孕中的影响也日益引起大家的重视。心理压力与不孕之间可能互为因果,不孕产生心理压力,心理压力不利于妊娠。从嗜海洛因者有闭经或性功能低下,人们注意到外源性阿片会影响生殖功能。国内外研究发现不孕患者表现出明显的烦恼、忧伤、焦虑、压抑,心理压力可能影响阿片系统,进而作用于下丘脑促性腺激素释放激素(GnRH),影响LH、FSH、PRL水平,影响生殖 [1~3] 。本研究采用放免双抗体法(RIA)测定19例不孕妇女月经周期中外周血β-EP、生殖激素水平,进行对照研究,并对不孕妇女做精神心理调查,了解β-EP在月经周期中的变化规律及对不孕的影响。

1 资料与方法

1.1 研究对象 选自我院生殖内分泌专科门诊19例月经周期正常(28±3)天,年龄22~39岁不孕妇女,不孕年限2~11年。对照组10例,为月经周期正常妇女,排除其他系统及精神心理疾病。两组对象于进入研究前半年内均未服用甾体激素及其它影响生殖内分泌系统的药物。

1.2 实验方法 (1)血浆β-EP于月经周期第8天、围排卵期、黄体中期(排卵后1周)的上午8~10时空腹采集肘静脉血,与抑肽酶2500IU和1%肝素50μl混匀,4℃、3000r/min离心15min,吸取上清液置于-40℃冰箱待测,测定方法按上海第二医科大学神经生物学教研室建立的β-EP放免测定方法进行,批内误差0.62% [4] 。(2)血清生殖激素测定:取测定β-EP同一时间的肘静脉血5ml,分离血清置于 -40℃冰箱保存,待一个周期结束时采用 125 I标记的放免双抗体一次测定FSH、LH、PRL、E 2 、P、T,批内、批间误差均小于10%。(3)不孕妇女心理调查及评分:对不孕妇女进行问卷调查,以精神症状出现的频度进行评分,用所有症状的积分评价心理压力的程度。(4)监测排卵:用B超、尿LH酶免测定、宫颈粘液改良Insler评分、基础体温进行联合排卵监测。

2 结果

2.1 血浆中β-EP的变化规律 见表1。不孕组及对照组月经周期中β-EP水平均为卵泡中期最低、围排卵期稍高、黄体中期显著升高(P<0.05)的上升趋势。不孕组各期β-EP水平均显著高于对照组(P<0.05)。

2.2 不孕组与对照组血清生殖激素水平比较 不孕组黄体期LH、E 2 及P水平明显低于对照组(P<0.05),T明显高于对照组(P<0.05),见表2。不孕组卵泡中期、围排卵期及黄体中期PRL显著高于对照组(P<0.01),见表3。

表2 不孕组黄体期LH、E 2 、P及T比较 (略)

表3 不孕组及对照组各期PRL水平 (略) 

2.3 不孕组β-EP与生殖激素关系 (1)卵泡中期:β-EP与FSH、LH呈显著负相关(r=-0.9176,r=-0.7124,P<0.01),β-EP与E 2 呈显著正相关(r=0.7297,P<0.01)。(2)围排卵期:β-EP与LH呈显著负相关(r=-0.5272,P<0.05),β-EP与PRL呈显著正相关(r=0.8128,P<0.01)。(3)黄体中期:β-EP与PRL呈显著正相关(r=0.8148,P<0.01),与P呈显著正相关(r=0.6192,P<0.01)。

2.4 不孕组β-EP与心理评分的关系 不孕组β-EP与心理状态评分呈显著负相关(P<0.001)。

3 讨论

曾有报道育龄妇女卵泡期β-EP呈低值,黄体期呈高 值 [5] ,本研究中不孕组与对照组β-EP水平均为卵泡中期最低、围排卵期稍高、黄体中期显著升高的周期性变化,与前述报道一致。β-EP在月经周期中的这种变化可能与体内雌、孕激素的水平变化有关,卵泡膜细胞、间质细胞及黄体颗粒细胞可产生β-EP,β-EP含量与卵泡大小呈正相关,孕酮可显著调节中枢阿片能的活力,孕酮和炔诺酮可增加去卵巢大鼠下丘脑中央基底部β-EP的含量。在黄体期E 2 处于较高水平而P处于最高水平,故β-EP水平显著升高,不孕组卵泡中期E 2与黄体中期P与β-EP呈显著正相关同样支持雌、孕激素水平影响β-EP活性的观点。
