Polycystic ovary syndrome (PCOS) is the most common gynecological endocrine disease, with a reported prevalence between 6% and 20%. The disease is characterized by high androgen, sparse ovulation or anovulation. It is reported that the risk of insulin resistance, type 2 diabetes, overweight or obesity, dyslipidemia, and cardiovascular disease increased in PCOS patients. In recent years, significant progress has been made in the diagnosis and treatment of PCOS patients, and pregnancy complications and offspring health in PCOS patients have gradually become the focus of attention. In this article, we reviewed the recent research progress of pregnancy complications, pregnancy outcome and long-term status of offspring in PCOS patients to provide a meaningful reference for clinical diagnosis and treatment strategies.

OBJECTIVE: To explore the relationship between the expression of interferon-induced protein with tetratricopetide repeats 1 (IFIT1) and liver cell apoptosis in the acute stress period after severe burns.
 METHODS: A total of 25 C57/129 adult mice were randomly divided into the normal control group (0 h) and the groups at 1, 6, 12 or 24 after severe burns (n=5 per group). A model with third degree (20% of the total body surface area) burn injury was established and then liver tissues were taken. IFIT1 expression was examined by Western blot. The expression of caspase-3 and -8 was measured by immunohistochemistry. Liver cell apoptosis was detected by terminal deoxynucleotidyl transferase mediated nick end labeling (TUNEL).
 RESULTS: After burns, IFIT1 expression was increased at 1 h, which reached the highest level at 
6 h followed by a decrease at 12 h, which reached minimum level at 24 h. The differences between groups were significant (P<0.01). The caspase-3 and -8 levels significantly increased after burns in a time-dependent manner (P<0.01). Although at 0 h and 1 h there was no significant increase in liver cell apoptosis, the increase reached significance from 6 h to 24 h (P<0.01).
 CONCLUSION The increase in IFIT1 expression after severe burns promotes liver cell apoptosis.

OBJECTIVE: To observe the influence of ropivacaine on the proliferation and migration of rat bone marrow mesenchymal stem cells (BMSCs) and provide basis for the clinical application of BMSCs. METHODS: Rat BMSCs were isolated and cultured by adherence method. Surface markers of BMSCs were examined by flow cytometry. Multipotent differentiation of BMSCs was detected by induced adipogenesis, osteogenesis and muscular differentiation. Proliferation of BMSCs was examined by CCK-8 and Brdu incorporation after ropivacaine treatment at different concentrations. Migration of BMSCs was tested by cell scratch assay and Millicell experiment. RESULTS: Cultured cells had representative appearance and surface markers of BMSC, and they had potential multiple differentiation. Ropivacaine treatment at 50 and 100 μmol/L significantly reduced the proliferation rate of BMSCs and Brdu incorporation rate. There was significant difference compared with the control group (P<0.05). Cellular scratch assay and migration experiment indicated that ropivacaine significantly reduced the migration of BMSCs. There was significant difference compared with the control group (P<0.05). All these mentioned effects of ropivacaine on BMSCs were dose-dependent. There was significant difference between groups (P<0.05). CONCLUSION Ropivacaine can significantly reduce the proliferation and migration of rat BMSCs, suggesting that the influence of local anesthetics on BMSCs has to be taken into account when BMSCs are used in clinical practice.

Objective Transcutural nursing has been the important part in modern nursing.Developing of the measurement instrument of cultural sensitivity of nursing undergraduates is the basic step in the research of transcultural nursing.Methods On the basis of the composition of cultural sensitivity of the nursing graduates,efforts were undertaken tO develop an instrument to classify cultural sensitivity to different levels through determination of nursing expert panel,and items were selected by trials through factor analysis.Results The scale consists of 41 items and includes three domains:cultural awareness.cultural understanding,cultural reaction,education background.The Cronbach's α was 0.849381.Items were selected by trials through factor analysis and the factor load was between 0.398～0.785.Conclusion The good validity and reliability were confirmed.The instrument Can evaluate the cultural sensitivity.
