Methods: The fetuses of interfamily pregnancy day 4, day 8 and day 12 were acted as experimental group, while the ones of intraspecific pregnancy day 4, day 8 and day 12 of embryo transfer and the uteri of pseudopregnant mice of corresponding time were employed as positive and negative groups respectively.

objective:to explore the value of laparoscopy in diagnosis and treatment of female infertility.methods:the clinical data of 139 cases of female patients with infertility were analyzed retrospectively.results:among 139 cases,55 cases with pelvic adhesion,34 cases with salpingitis,20 cases with endometriosis,and 14 cases with polycystic ovary.the pregnancy rates were 47.27%,41.18%,55.56% and 46.15% respectively after laparoscopic surgery.pelvic adhesion salpingitis and endometriosis were the major cause of female infertility.conclusions:laparoscopic technique can find out the reason of infertility more earlier and more directly and provide timely therapy.so it has excellent clinical effect.

目的：探讨腹腔镜诊治女性不孕症的应用价值。方法：回顾分析我院2004年12月至2007年12月应用腹腔镜诊治女性不孕症139例患者的临床资料。结果：139例中盆腔粘连55例，输卵管炎34例，子宫内膜异位症20例，多囊卵巢综合征14例，术后妊娠率分别为47.27%，41.18%，55.56%，46.15%。盆腔粘连、输卵管炎、子宫内膜异位症是引起女性不孕的主要盆腔病因。结论：应用腹腔镜技术能早期、直观、准确的明确不孕症输卵管及盆、腹腔病因并可同时予以针对性治疗，在直视下通液，动态观察输卵管通畅度和形态，大大降低了常规通液术的假阳性、假阴性率。

Methods: The fetuses of interfamily pregnancy day 4, day 8 and day 12 were acted as experimental group, while the ones of intraspcific pregnancy day 4, day 8 and day 12 of embryo transfer and the uteri of pseudopregnant mice of corresponding time were employed as positive and negative groups respectively.

以科间妊娠D4、D8、D12的孕体为实验组，小鼠同种移植妊娠D4、D8、D12的子宫孕体和相应时间假孕小鼠的子宫为阳性和阴性对照。

It was found that during all three stages, the expression levels of Dnmt1 mRNA in the epithelial cells of the pregnant mice were significantly lower than those in the pseudopregnant mice (P.05), and the level of Dnmt1 protein expression in the pregnant mice was significantly decreased as compared with that in pseudopregnant mice at the 4-cell stage.

结果 Dnmt1蛋白主要表达于上皮层；妊娠组小鼠各期Dnmt1 mRNA表达水平均显著性低于同期假孕组(P.05)，妊娠组4细胞期Dnmt1蛋白表达水平显著性低于同期假孕组(P.05)。

Spaying also prevents false pregnancy, which occurs in females from time to time.

喷施还可以防止假妊娠，其中女性时有发生的时间。

The infection rate of Vulvovaginal candida of pregnant women is higher than normal people. The candida albicans is the most important pathogen of VVC, but noncandida albicantia are rising. The immunological abnormity of body and the change of vaginal environment are important reasons for the occurrence of VVC.

妊娠期妇女外阴阴道假丝酵母菌的感染率较正常人为高，其中白色假丝酵母菌是VVC最常见的致病菌，但非白化有上升趋势，机体的免疫异常及阴道环境的改变是VVC发生的重要原因。

It was shown that: 1 MMP2 activity reached the highest level during proestrus, and was lowest during diestrus; 2 MM2 acti vity was increased from the first day of pregnancy, peaked on day 4 of pregnancy; but decreased significantly at day 7 of the pregnancy. 3 MMP2 activity was obviously higher on day 1 of pseudopregnancy than on the other days, and its activity decreased gradually, reached the very low level at day 4 of pseudopregnancy and maintained the low level until day 7; 4 MMP2 activity was decreased significantly 24 hours after injection of 17βestradiol ( 01 mg) at metaestrus, while MMP2 activity had no change after progesterone (04 mg) injection.

明胶酶A活性变化如下：1在大鼠的动情前期明胶酶A的活性最高，间情期最低；2在妊娠早期(1～7天)的卵巢中，明胶酶A的活性在妊娠第4天达到最高，第1～3天及第5、6天其活性也较高，但第7天则明显下降；3在假孕(1～7天)大鼠的卵巢中，明胶酶A的活性在假孕第1天最高，第2、3天略下降，从第4天到第7天，其活性都处于较低水平；4动情后期大鼠皮下注射雌二醇(0.1mg/只)24小时后，明胶酶A活性明显上升。
