Diabetic mellitus induced erectile dysfunction (DIED) is a common complication of type 2 diabetes mellitus (T2DM), which seriously affects the physical and mental health of male T2DM patients. The occurrence of DIED involves a variety of pathophysiological changes such as vascular tissue, nerve, endocrine and so on. But the traditional treatment of erectile dysfunction is not ideal for DIED. Glucagon like peptide (GLP)- 1 receptor agonist has been widely used as a new drug for the treatment of diabetes, and the representative drugs are exenatide and liraglutide. Existing research shows that it can improve endothelial cell function, neuropathy and sex hormone secretion, reduce body weight and insulin resistance. Therefore, these drugs may be a new choice for patients with DIED.

Objective To investigate the effect of continued nursing on postoperative outcomes of discharged patients with chronic suppurative otitis media.Methods Toally 198 discharged patients were randomized into the control group (n=98) and the observation group (n=100).The patients in both groups received normal health education and additionally the continued nursing was used in the observation group for health education by way of phone call follow-up,on-the-spot consultation and QQ consultation.The mastery of related knowledge and skills,incidence of secondary tympanic membrane and readmission rate were compared.Results Six months after discharge,the observation group was significantly better than those the control group in the mastery of related knowledge and skills (P＜0.05).The incidence of secondary tympanic membrane perforation was not statistically significant between the groups(P＞ 0.05).The readmission rate at the second week and the third week between the two groups had no statistically significant difference (P＞ 0.05).However,the readmission rate at the first,second,third and sixth month were statistically different (P＜0.05).Conclusion Continued nursing to the postoperative discharged patients with chronic suppurative otitis media can improve the follow-up rate after discharge and self-nursing capacity,and as a result promote their recovery.

Objective The aim of this study is to evaluate whether video -assisted thoracoscopic surgi-cal( VATS) lobectomy is as effective as open thoracotomy lobectomy for complete dissection of the mediastinal lymph node(MLN).Methods Patients with clinical stage N0 lung cancer who underwent lobectomy between January 2008 and June 2013were retrospectively evaluated based on the LN station resected and lobectomy proce -dure used,and a resection ratio was calculated .Nodal stage and the proportion of patients ,from whom at least three MLNs and station 7were dissected and compared by lobectomy type .Results Of the 201 patients enrolled in the study,84 and 117 underwent VATS and open thoracotomy lobectomies ,respectively.The mean number of LNs dissected at station 3a was similar in the two groups (1.34 ±2.58 vs.1.52 ±1.78;P>0.05),but the re-section ratio differed(39%sv .63%;P <0.05).However,there were no differences at stations7 and 9R in terms of the number of LNs dissected or resection ratio for the right -sided approaches (P >0.05).There were no differences in the number of LNs dissected or resection ratio between the two groups for stations 4 L,5 L6, L,7 L, and9 L for the left-sided approaches .Only station 8L showed significant differences between the VATS and open thoracotomy groups in the number of LNs dissected (0.12 ±0.44 vs.0.46 ±0.71;P<0.05)and resection ratio (8%vs.36%;P<0.05).There were no differences in the number of LNs dissected or resection ratio between groups for station 7:82.1%of patients in each group had at least three MLNs and station 7 removed(P>0.05). The Kaplan-Meier 5-year survival was also similar between the two groups (log-rank test,P>0.05).Con-clusion VATS lobectomy is as effective as open thoracotomy lobectomy for the dissection of MLNs .Thus,VATS lobotomy resection will continue to be offered as the best choice for patients with clinical stage N0.

[ ABSTRACT] AIM:To investigate the change of phosphorylation of tau protein and expression of cyclooxygenase 2 ( COX-2) in colon submucosal neurons of enteric nerve system in inflammatory bowel disease ( IBD) rats induced by tri-nitrobenzene sulfonic acid (TNBS).METHODS:Male rats (n=30) were randomly assigned to 3 groups (n=10 each):control group, IBD group and TNBS group.The IBD rats were induced by TNBS+ethanol enema for 14 d.The control and TNBS rats were given an equal volume of saline and TNBS, respectively.The general situation and the histopathologic change of the rat colon were observed.Immunofluorescence was used to check the change of phosphalated tau protein and COX-2 expression in the submucosal neurons of the colon.The expression of COX-2 and phosphorylated tau231 and tau262 in the rat colon submucosal neurons was observed by double immunofluorescence staining.RESULTS:Compared with con-trol group, the number of neurons in the colon of IBD rats decreased obviously and the expression of phospholated tau231 and tau262 was significantly increased.The number of neurons in the colon of TNBS rats showed no significant difference compared with control rats.The rat neurons in control group and TNBS group did not express COX-2.COX-2 expression was observed in the nucleus and cytoplasm of colonic neurons in IBD rats, which showed significantly different from control and TNBS rats.CONCLUSION:The decreased neurons in the enteric nerve system of IBD rats might be associated with the phosphorylation of tau protein and the expression of inducible COX-2.

Objective To explore the dynamic changes in the plasma levels of thrombomodulin(TM)with traumatic hemor-rhagic shock (THS).Methods The model of the THS with gradient decerease in the systolic blood pressure was eatablished in 1 7 rats without specific pathogen.The arterial blood during the different phase of shock,i.e.when the systolic pressures were three forth,one second,two fifth of the basis systolic blood pressure,one fifth of the basic systolic blood pressure and 10mmHg,was collected and TM levels in the plasma were determined by the double antibody sandwich method of enzyme-labeled immunosorbent assay (ELISA)and analyzed.Results There were significant differences in plasma levels of TM be-tween groups,with TM levels in T2~T3 period of time increased with the extension of time,and TM levels in T4~T5 peri-od of time decreased with the extension of time,and TM levels in T5~T6 period of time increased with the extension of time.Conclusion The animal model of THS was related to the systolic pressure during the shock,may be helpful to assess-ment changes in blood loss.The dynamic observation of the plasma levels of TM which is a good index of the damage to the vascular endothelial cells,may be helpful to assessment of the THS is related to the degree of damage to the vascular endo-thelial cells.

Objective To investigate the effect of interferon-γ(IFN-γ) on the expression of indoleamine 2,3-dioxygenase(IDO),and tryptophanyl-tRNA-synthetase (TTS) in thyrocytes; and to study the relevant immunopathological significance in Graves' disease.Methods The expressions of IDO and TTS genes in IFN-γ stimulated Nthy-ori3-1 cell line and human thyrocytes,as well as in human thyroid tissues were determined by realtime quantitative PCR.Results IDO and TTS genes were expressed slightly in both Nthy-ori3-1 cell line and human thyrocytes,and were significantly up-regulated after IFN-γ stimulation(P＜0.01).Compared to healthy controls,TTS mRNA level was higher in thyroid tissues of patients with Graves' disease (P =0.018 2),while IDO mRNA level showed no difference,but was notably correlated with IFN-γ mRNA level (R2 =0.716,P =0.002).Conclusion In the early stage of Graves' disease,thyrocytes may decompose local tryptophan by enhancing the expression of IDO and TTS under IFN-γstimulation,thus inhibit auto-reactive function of lymphocytes and balance excessive autoimmune reaction.
