Objective To investigate the Expression of interleukin-18(IL-18)and cyclooxygenase2(COX-2)in endometriosis.Methods Enzyme linked immunosorbent assay and innunohistochemistry were used to detrermine the levels of interleukin-18 in peritoneal fluid and serum,the expression difference of cyclooxygenase2 in ectopic endometrium with endometriosis and the normal control.Results The levels of interleukin-18 in peritoneal fluid and serum were higher than that of normal control,the expression of cyclooxygenase2 in ectopic endometrium with endometriosis were higher than that of normal control,and the degree in stage of Ⅲ、Ⅳ were higher than those in stage of Ⅰ、Ⅱ.Conclusions IL-18 and COX-2 is related to the endometriosis,the further studying of IL-18 and COX-2 may be helpful in the diagnosis and treatment of this disease.

Objective To explore the effect of psychological capital on nurses′job performance and satisfaction and the mediating role of positive emotion. Methods 523 nurses employed in eight hospitals in Anhui province were selected through multistage sampling and interviewed using questionnaires . Structural equation modeling was used to test the proposed relationships. Results Nurses′psychological capital was significantly positive correlated with positive emotion (r=0.473), job performance (r=0.505) and satisfaction (r=0.358), all P<0.01. Nurses′positive emotion was also significantly positive correlated with job performance (r=0.343) and satisfaction (r=0.452) , all P<0.01. The mediating test showed that nurses′positive emotion acted as a partial mediator between psychological capital and job satisfaction while medium effect accounting for 61.5%(0.24/0.39) of the whole effect. Nurses′positive emotion also played a role of being a partial mediator between psychological capital and two aspects of job performance, professional development ability and scientific research innovation ability,while medium effect accounting for 10.0%(0.06/0.60) and 12.9%(0.08/0.62) of the whole effect, respectively. Conclusions Psychological capital affects nurses′job performance and satisfaction and suggests nurses′positive emotion play a role of being a partial mediator in this relationship.

Methods 60 patients with endometriosis surgery were randomly divided into 30 cases of I group and 30 cases of II group,I group was treated with mifepristone on the first days after menstruation 12.5mg/d,qd,II group was given triptorelin 3.75mg,every 28 days for 1 times,treated for 3 months,the symptoms and signs before and after treatment were observed,then menstruation and dysmenorrhea score were evaluated,Elbow vein blood was taken out for calculat-ing CA125 and serum antiendometrial antibody,the clinical efficacy were evaluated and the adverse reactions were observed,all patients were followed up for 1 years,then 1 years cumulative pregnancy rate were recorded.Results The CA125,EMab,menstrual score,dysmenorrhea score of I group and II group after the treatment were (18.2 ±2.8)U /mL and (8.8 ±3.2)U /mL,(405.2 ±141.1)pg/mL and (202.1 ±79.8)pg/mL,(18.85 ±6.32)score and (7.68 ± 4.19)score,(1.91 ±0.35)score and (0.95 ±0.63)score,all index of both group after treatment were significantly lower than those before treatment(t =8.433 and 14.824,7.659 and 14.578,20.772 and 26.286,15.853 and 19.513,P <0.01),all index of II group after treatment were significantly lower than those of I group(t =5.711, 6.632,6.675,5.624,all P <0.01).The total effective rate,pregnancy rate,recurrence rate of I group and II group were 96.67% and 93.33%,53.33% and 50%,3.33% and 6.67%,the difference were not statistically significant (P >0.05);the irregular vaginal bleeding rate of I group was 23.33%,the II group were 3.33%,χ2 =5.192,P <0.05.Conclusion Triptorelin and mifepristone has same clinical effect in endometriosis postoperative,but triptorelin can reduce more effectively the CA125 and anti endometrium antibody,abnormal vaginal bleeding and reduce dysmen-orrhea postoperative,postoperative recurrence rate and pregnancy rate is good,can be used as a recommended drugs in the treatment patients with endometriosis surgery.

Helicobacter pylori is a predominant pathogen inducing long-term chronic infection of stomach. Its outer membrane proteins (OMPs) mainly include lipoprotein, fimbriae protein and some adhesions. The adhesions are closely related to the pathogenic processes of adherence, colonization, persistent infection and severe clinical outcomes. In addition, the fact that adherence is vital for colonization and pathogenicity has made it a focus to study the vaccines against adherence. The OMPs related to adherence, their receptors, mechanisms of adherence, and the vaccines are summarized in this review.
