Transforming growth factor (TGF)-β1 is involved invasion of human trophoblasts. However, the underlying mechanisms remain unclear. In this study, we performed Transwell assay and found that TGF-β1 promoted the invasion of trophoblast cell line JEG-3. Treatment with TGF-β1 up-regulated the expression of receptor-regulated Smad transcription factors Smad2 and(More)
The results of several studies about the effectiveness of recombinant luteinizing hormone (rLH) supplementation in poor responder in vitro fertilization (IVF) patients were conflicting. To evaluate the current available data regarding the efficacy of rLH supplementation in poor responders, a meta-analysis was performed. A systemic search was performed(More)
To reevaluate the effect of isolated teratozoospermia on IVF and determine if there was any therapeutic benefit to isolated teratozoospermia by ICSI, since there are no widely accepted criteria for the treatment technique about isolated teratozoospermia. A total of 441 couples with >20 million and progressive motility >30 % sperm undergoing their first(More)
This study was aimed to explore a simple and applicable method of separating mature sperms from human testicular tissue for intracytoplasmic sperm injection and embryo transfer. The suspension of human testicular tissue was cultured in 10% human serum albumin and human tubule fluid with different concentrations (0 u/ml; 50 u/ml; 100 u/ml; 150 u/ml; 200(More)
We explored microRNA301 diagnosis value in hepatocellular cancer (HCC), attempting to provide novel insights for early detection, effective prevention, and timely treatment. 42 patients with HCC and 38 controls composed of 9 liver cirrhosis (LC), 9 chronic hepatitis B (CHB) and 20 healthy individuals were investigated in the study. Serum microRNA301(More)

METHODS We conducted a population-based cross-sectional study in women who were over 45 years old in the central city and the nearby county of Chengdu. RESULTS The(More)
Cytochrome P450 1A1 (CYP1A1) polymorphisms were implicated in endometriosis risk, but individual published studies showed inconclusive results. Thus, a meta-analysis was performed to clarify the effect of CYP1A1 polymorphisms on endometriosis risk. PubMed, Embase, and CNKI databases were searched to identify the eligible studies focusing on the associations(More)
To investigate the influence of the interleukin-10 gene promoter polymorphisms on the susceptibility of endometriosis, we examined the association by performing a meta-analysis. The PubMed, Embase, HuGE Navigator and CNKI were searched to identify eligible studies. We then conducted a meta-analysis to examine the association between interleukin-10 gene(More)
OBJECTIVE To study the antigen presentation ability of spleen macrophage from Balb/c mouse during late gestation. METHODS The spleen of Balb/c mouse during late gestation was collected aseptically and macrophage was separated; the mice in estrus were used as control. The ability of macrophage to prime original T cells to human gamma globulin antigen(More)
Selectins are a family of calcium-dependent, type I transmembrane, carbohydrate-binding glycoproteins. Selectins and their ligands are not only involved in physiological processes such as leukocyte homing and pathological processes such as cancer, but also play an essential role in the human implantation. L-selectin and its ligands participate in the(More)
