Patients in the group A were treated by dinoprostone suppositoriesository, patients in the group B were treated by oxytocin, patients in the group C were treated by the cervical dilation balloon, the cervical, childbirth, complications and newborns in the 3 groups were observed and compared. Results Compared with group B and group C, late pregnancy induced labor curative effect in group A was better:cervical Bishop score was higher after intervention 6h and 12 h (P<0.05), and promote cervical mature rate and success rate of induced labor were higher(P<0.05), labor time was shorter (P<0.05).The incidence of delivery complications was lower(P<0.05).Conclusion Dinoprostone suppositories can reduce labor time significantly in the treatment of late pregnancy, and improve the success rate of induced labor, the effect is superior to oxytocin and cervical dilation balloon.

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

Objective To investigate the effect of berberine on endoplasmic reticulum stress PERK apoptosis pathway in HK-2 cells by high fructose.Methods HK-2 cells were grown in DMEM/F12, containing 10% fetal bovine serum (FBS) and divided randomly into four groups: normal control group (Group C); Fructose group (Group F): it contains 25mmol/L fructose culture; Berberine group (Group B): 25mmol/L fructose + 10μmol/L berberine treatment group; TUDCA group (Group T):25mmol/L fructose +2μmol/L TUDCA culture group; Cells were collected after culturing 24h. The expression of glucose-regulated protein 78 (GRP78), CHOP protein and the phosphorylation levels of PERK, eIF2α were tested by Western blotting. The cell cycles were detected by flow cytometry and the apoptosis of cells were detected by TUNEL staining.ResultsWestern blotting showed that the expression of GRP78 and CHOP protein in group F was significantly higher than that in group C, and the levels of p-PERK and p-eIF2α in group F were significantly higher than those in group F. Compared with group F, GRP78, CHOP, p-PERK and p-eIF2α in group B and T were significantly lower (P<0.05). The expression of GRP78, CHOP, p-PERK and p-eIF2α in group B had no significant difference. Flow cytometry and TUNEL staining showed that the cell viability of fructose group was significantly lower than that of C group, and the apoptotic index was significantly higher than that of group C (P<0.05). Compared with group F, the activity of HK-2 cells in group B and T significantly increased, otherwise the apoptosis index significantly decreased, and the difference was statistically significant (P<0.05). Compared with group T, the viability index and apoptosis rate of group B had no significant difference (P>0.05).Conclusion Persistent high fructose can activate the intracellular PERK pathway in HK-2 cells, causing endoplasmic reticulum stress. Berberine can inhibit the fructose-induced PERK and eIF2α phosphorylation, down-regulated the expression of GRP78, CHOP protein, thus by regulating PERK Pathways to alleviate cell cycle arrest and reduce cell apoptosis.

Objective:To understand the prevalence of Neisseria gonorrhoeae (NG) infection and related factors in outpatients of sexually transmitted disease (STD) in Shenzhen and provide scientific evidence for targeted intervention. Methods:A cross-sectional study was conducted in STD outpatients who were aged 18-49 years, had had sexual intercourse, had not received antibiotics in the last 2 weeks and sought medical cares in 22 medical institutions in 6 districts of Shenzhen from 15 April, 2018 to 16 May, 2018, their basic information and urine samples were collected, and NG in urine sample was detected by nucleic acid amplification test. Logistic regression analysis was conducted to identify the related factors for NG infection.Results:The information collection and sample collection were completed for 8 324 STD outpatients, among these STD outpatients, 196 were NG positive, with a positive rate of 2.4% (196/8 324). The positive rate of NG in men (5.8%, 148/2 567) was higher than that in women (0.8%, 47/5 742) ( χ2=189.43, P<0.05). Aged 24 years or below ( OR=2.11, 95% CI: 1.44-3.09), single/divorced/widowed ( OR=1.98, 95% CI:1.38-2.84), having casual sex in the last 3 months ( OR=1.77, 95% CI:1.29-2.43) were the related factors for NG infection. Conclusions:We found that NG infection rate was high in STD outpatients in Shenzhen. The infection rates in men and in women differed obviously. It is necessary to conduct gonorrhea screening and intervention in STD outpatients with high-risk behaviors, such as extramarital and casual sex behaviors, and standardize the treatment to reduce the incidence and spread of gonorrhea and other STDs.

Suppressor of cytokine signaling (SOCS) family proteins are a group of negative regulatory factors that plays important roles in the negative regulation of cytokine responses by terminating the activation of the JAK-STAT and other signaling pathways. hTe family is composed of eight structurally related proteins. mainly through the inhibition of the activation of JAK-STAT signaling pathway and regulates cell proliferation, differentiation and apoptosis. In the process of tumor progres-sion, the promoter CG island hypermethylation, gene mutation, gene deletion and inactivation lead to the abnormal expres-sion of SOCS protein make JAK-STAT continuous activation, resulting in the development and metastasis of tumor. Here, we review the SOCS family members found, composition and molecular structure, the domain of the function, and the latest progress of development in tumor. Based on the important role of SOCS in tumor development, SOCS as a negative regulator factor represent a kind of tumor suppressor genes, has become a new target for tumor therapy.

Laboratory testing is a vital chain in the prevention and control of genital chlamydia trachomatis infection. The prevalence of genital chlamydia trachomatis infection is high, but the detection rate of the infection is low in men who have sex with men (MSM) in China. Self-sampling for genital chlamydia trachomatis detection by MSM is a new option to address this problem, which would play a significant role in expanding genital chlamydia trachomatis infection screening in this population. This paper summarizes the progress in research of self-sampling for the detection of genital chlamydia trachomatis and the related factors in MSM both at home and abroad to provide reference for the promotion of self-sampling for the detection of genital chlamydia trachomatis in this population.

Background and objective TheEML4-ALK fusion gene is a newly discovered driver gene of non-small cell lung cancer and exhibits special clinical and pathological features. hTe JAK-STAT signaling pathway, an important downstream signaling pathway of EML4-ALK, is aberrantly sustained and activated in EML4-ALK-positive lung cancer cells fusion gene, but the underlying reason remains unknown. hTe suppressor of cytokine signaling (SOCS) is a negative regula-tory factor that mainly inhibits the proliferation, differentiation, and induction of apoptotic cells by inhibiting the JAK-STAT signaling pathway. hTe aberrant methylation of theSOCS gene leads to inactivation of tumors and abnormal activation of the JAK2-STAT signaling pathway. hTe aim of this study is to investigate the methylation status of the SOCS3 promoter in EML4-ALK-positive H2228 cells and lung cancer tissues.Methods hTe methylation status of the SOCS3 promoter in EML4-ALK-positive H2228 lung cancer cells and lung cancer tissues was detected by methylation-speciifc PCR (MSP) analysis and veri-ifed by DNA sequencing. hTe expression levels of SOCS3 in H2228 cells were detected by Western blot and Real-time PCR analyses atfer treatment with the DNA methyltransferase inhibitor 5'-Aza-dC.Results MSP and DNA sequencing assay results indicated the presence of SOCS3 promoter methylation in H2228 cells as well as in three cases of seven EML4-ALK-positive lung cancer tissues. hTe expression level of SOCS3 signiifcantly increased in H2228 cells atfer 5′-Aza-dC treatment.Conclu-sion hTe aerrant methylation of the SOCS3 promoter region in EML4-ALK (+) H2228 cells and lung cancer tissues may be signiifcantly involved in the pathogenesis of EML4-ALK-positive lung cancer.
