Great progresses have been achieved in the subject along with the deep development in life science. Modern reproductive immunology includes immunological regulation of fertility, materno-fetal immuno-regu-lation, and neuro-reproductive endocrino-immune network. With the integrated traditional Chinese and western medicine (ICWM) applied to reproductive immunology it has been greatly enriched in research contents and depth. The present review is to introduce the recent progresses in research of integrated medicine on reproductive immunology.展开更多

Methods: Thirty-five patients suffering from unruptured TP were divided into two groups at random, to the 19 patients in the treated group, the treatment of combined IMI with Ectopic Pregnancy decoction No. 2 (EP2, a traditional Chinese medical decoction) was applied, and to the other 16 patients in the control group, IMI alone was applied for control. Serum concentrations of human chorionic gonadotro-pinβ(β-HCG), size of the gestational sac, existent time of fetal cardiac beat and peritoneal fluid were measured before and after treatment. And hysterosalpingography were performed 6 months after ending the treatment to verify the presence of tubal obstruction and the condition of relapse.Results: The treatment of all the 35 women was successful. The recovery duration of serumβ-HCG, disappearance duration of TP sac and existent time of peritoneal fluid in the treated group were 20.0±7. 8 days, 1.2±0. 7 months and 10. 7±2. 9 days respectively, which were significantly different from those in the control group (24. 4 ±8.1 days, 3.6±1.7 months and 19.1±3. 2 days respectively(P<0. 05, P<0.01 and P<0. 05 respectively), but the existent time of fetal cardiac beat in the two groups (8.8±1. 9 days vs 9.0±1. 3 days) was not significantly different (P>0.05). The post-treatment oviduct obstructive rate in the two groups was 10.5% and 43.8% respectively, that in the treatment group was less significant (P<0.05). The relapse rate of EP in the treatment group was insignificantly different from that in the control group (5.3% vs 18.8%, P>0.05). Conclusion: The two therapies (IMI alone and IMI combined with EP2) could obtain e-qual efficacy in curing TP. Compared with IMI alone, the combined therapy appears to have the effects of accelerating the resorption of gestational sac and peritoneal fluid, improving the patency of fallopian tube and ameliorating the circumstance of pregnancy, which is favorable to improvement of the re-pregnancy rate and reduction of the re-occurrence of ectopic pregnancy as well as to the enhancement of the effect of IMI in killing trophocytes. But there is not enough proof to show the potency of EP2 in killing embryo.展开更多

Study design: A group of women with endometriosis (n = 18, infertile) was compared with patients with uterine leiomyoma (n = 16, fertile), unexplained infertility (n = 5, infertile), and healthy women (n = 16, fertile). MCP-1 expression levels were evaluated by ELISA assay. The data obtained were statistically analyzed using the Mann-Whitney test. P-Values < 0.05 were considered as significant. Results: MCP-1 concentrations (median; range of values) in serum were as follows: women with endometriosis (221; 101-635 pg/ml), women with unexplained infertility (167, 114-234 pg/ml), women with uterine leiomyoma (137; 88-200 pg/ml), and healthy donors (123; 98-194 pg/ml). Significant differences were observed in the women with endometriosis compared with those with uterine leiomyoma (p = 0.02) and healthy donors (p = 0.002). Among the women with endometriosis, the level of significance in MCP-1 level at rAFS stages III-IV was higher than that at rAFS stages I-II compared with healthy donors and women with leiomyoma (p = 0.002 and p = 0.02, respectively). Conclusions: These data show that an increased level of MCP-1 can characterize infertile women with endometriosis. However, further studies are needed to be able to determine whether increased MCP-1 chemokine expression can be related to infertility or is a result of endometriosis progress.展开更多

文摘Objective:Villoglandular papillary adenocarcinoma(VGPA)of the uterine cervix is a subtype of cervical adenocarcinoma.In the present study,we summarized the clinical features of VGPA of the uterine cervix and discussed the potential indications for a conservative treatment.Methods:A retrospective review of clinical characteristics and treatment aspects of 10patients with VGPA at the Obstetrics and Gynecology Hospital of Fudan University was conducted between January 2007 and December 2016.Almost all of the existing 40 English papers on“villoglandular papillary adenocarcinoma[title/abstract]”identified from PubMed were obtained.Clinical data from these papers were analyzed in terms of age,International Federation of Gynecology and Obstetrics(FIGO)stage,recurrence rate,mortality,and conservation treatment aspects.Results:The median age of 10patients with VGPA was 40years.All cases had Stage IB 1 disease.Seven patients underwent human papillomavirus examinations,which revealed 6 positive and 1 negative case(s)of infection.Six patients underwent ThinPrep cytologic tests,which revealed 4patients with atypical glandular cells,1 with a high-grade squamous intraepithelial lesion,and 1 who tested negative for intraepithelial malignancy.None of the patients had lymph node metastases.During the 6-114months of follow-up,no disease recurrence or death occurred.Of note,one patient who received conservative treatment successfully became pregnant.Conclusions:VGPA can be detected at an early FIGO stage with excellent prognosis.For young patients who do not exhibit poor prognosis factors,conservative treatment may be the first treatment choice based on overall assessment of clinical conditions.
