[Chinese Herbs Combined Three-stage Sequential Therapy for Conservative Treatment of Ectopic Pregnancy].

Objective To observe the clinical efficacy and safety of three-stage sequential thera- py [(methotrexate + mifepristone + Gongwaiyun Recipe (GR)] for conservative treatment of ectopic pregnancy. Methods Recruited were 250 ectopic pregnancy patients, who received conservative treat- ment at Affiliated Ganzhou Hospital of Nanchang University and Ruijin Maternal & Child Health Care Hos- pital from January 2010 to December 2014. They were assigned to the observation group (153 cases) and the control group (97 cases) according to different treatment methods used.

Genetic variations in cytotoxic T-lymphocyte antigen-4 and susceptibility to cervical cancer.

Cytotoxic T-lymphocyte antigen-4 (CTLA-4), a molecule expressed predominantly on activated T cells, plays an important role in the down-regulation of T-cell activation. To evaluate the potential effects of CTLA-4 gene polymorphisms on susceptibility to cervical cancer, we genotyped polymorphisms in CTLA-4 (- 318 T/C, CT60 G/A,+49 G/A, - 658 T/C, and - 1661 G/A) and calculated odds ratios for the genotype and allele distributions between patients and controls. We then examined the functional relevance of the polymorphisms using enzyme-linked immunosorbent assays (ELISAs), in vitro lymphocyte proliferation assay, and cytotoxic assay.

Effects of estrogen on CD4(+) CD25(+) regulatory T cell in peripheral blood during pregnancy.

Objective: To investigate the effects of estrogen (E2) level on regulatory T cells (Treg) in peripheral blood during pregnancy.

Methods: A total of 30 healthy non-pregnant women were selected as control group, 90 pregnant women of early, middle and late pregnancy and 30 postpartum women at 1 month after parturition were selected as experimental groups including early pregnancy group, middle pregnancy group and late pregnancy group; the proportions of CD4(+)CD25(+) Treg and CD4(+)CD25(+)CD127(-) Treg among CD4(+)T cells were detected by flow cytometry; the serum estrogen content in peripheral blood was detected by electrochemical immune luminescence method.

Results: E2 level was coincident with the change of Tregs number during pregnancy.
