健康成年男子黄体生成素脉冲释放分析

对７名健康男子每１０分钟采血一次，历时２４小时，测定血清ＬＨ浓度并进行脉冲分析。结果平均ＬＨ脉冲频率为１６．９±２．１次／２４ｈ，周期为８７±ｌ０ｍｉｎ／次，脉冲间期为３０～３００分钟不等，幅度为１．０±０．６ＩＵ／Ｌ。采血间期为５分钟的另外３名健康男子１２小时ＬＨ脉冲频率为１０．３±０．９次，周期为６９±８分钟，间期为６２±３７分钟，幅度为１３±０．４ＩＵ／Ｌ。采血间期和设定的脉冲阈值不同对ＬＨ脉冲频率和脉冲周期均有影响。

血清FSH、LHⅡ、E2检测在更年期妇女中的意义

目的:探讨血清FSH、LHⅡ、E2检测在更年期妇女中的意义。方法:采用电化学发光法对217例更年期妇女进行血清FSH、LHⅡ、E2测定,并与100名22～35生育年龄妇女对照。结果:更年期组FSH、LHⅡ、E2分别为41.9±17.8mIU/m1、28.6±11.3mIU/m1和27.5±9.2pg/ml,与正常对照组比较,FSH、LHⅡ值明显增高,E2明显降低,差异非常显著(P<0.01)。结论:血清FSH、LHⅡ、E2检测可作为诊断更年期综合征、卵巢早衰的特异性指标。更年期妇女40岁以后每年定期检测FSH、LHⅡ、E2激素水平,对提高生命质量有着重要意义。

Analysis on Polymorphisms of GHR Gene in Improved Hybrid Yellow Cattle Groups from Liupan Mountain Area in Ningxia

[Objective] The paper aimed to analyze the polymorphism of the growth hormone receptor （GHR） in improved hybrid yellow cattle group from Liupan Mountain area in Ningxia Autonomous Region,so as to provide technological basis for hybrid improvement. [Method] Polymerase chain reaction-restriction fragment length polymorphisms （PCR-RFLP） technology was carried out to examine polymorphisms of GHR gene of 70 individuals. [Result] The target fragment of 338 bp was amplified. The PCR product digested by restriction enzyme Alu I showed polymorphisms. The frequencies of the two genotypes （AA,BB） were 75.71% （53 individuals） and 24.29% （17 individuals）,respectively. [Conclusion] Two genotypes of GHR gene were detected in improved hybrid yellow cattle groups from Liupan Mountain area in Ningxia.

腹腔镜治疗多囊卵巢综合征42例临床分析及护理体会

目的:探讨腹腔镜卵巢打孔术治疗多囊卵巢的效果。方法:对42例多囊卵巢综合征患者行腹腔镜下卵巢打孔术。结果:术后患者月经情况改善,术后促黄体生长激素睾酮与术前相比,明显下降。术后排卵率83.3%,妊娠率83%。结论:腹腔镜卵巢打孔术具有损伤小,粘连轻,恢复快,疗效高的特点,是治疗多囊卵巢综合征的有效方法。
