MAPKKK (MEKK1 or ASK1)/MAPKK (SEK1 or MKK7)/JNK signal cascade is an important pathway which mediates apoptosis. MAPK phosphotase can deactivate JNK by dephosphorylation of JNK.The interaction between JNK and c-Jun can also be negatively regulated by NO through S-nitrosylation. SGK1 or Akt can result in deactivation of SEK1 through its phosphorylation at the Ser78 site.The c-FLIPL can block this cascade through binding with MKK7.GST Mu1-1 interferes and suppresses MEKK1-mediated apoptosis. GST Pi 1-1 and TRX have a dose-dependent inhibitory effect on ASK1 through forming protein complex. The deactivation of JNK can enhance drug resistance of tumor cells and counteract the injury from a wide variety of stimulus. Here,how these proteins induce deactivation of the pathway and mediate anti-apoptosis has been discussed.

Objective To investigate the etiology of and therapy for duodenal fistula caused by distal common bile duct operation. Methods An retrospective analysis of 19 cases of duodenal fistula after distal common bile duct operation was made.All cases received surgical management after the fistula was identified.Surgical procedures included abdominal abscess drainage in 2 cases, gastrostomy and jejunostomy combined with abscess drainage in 11 cases, gastrostomy and jejunostomy combined with duodenal repair?abscess drainage in 3 cases,gastrojejunostomy with pyloric exclusion combined jejunostomy in 1 case, repair of fistula with padicled intestinal seromuscular patch combined with gastrostomy and jejunostomy in 1 case, and repair of fistula with padicled intestinal seromuscular patch combined with gastrostomy and jejunostomy plus sphincteroplasty in one case. Results Among 19 cases,15 were cured. Two died of gastrointestinal bleeding, one of severe retroperitoneal infection,one of severe pancreatitis. ConclusionsEarly diagnosis is of great importance for the treatment of duodenal injury. Drainage is the mainstay for the treatment of iatrogenic duodenal fistula, while enough enteral nutrition should be given to accelerate spontaneous closure of the fistula.

Objective To explore the effects of different period of insulin-like growth factor-1(IGF-1)on B cell lymphoma/leukeamia-2 gene(BCL-2)and BCL-2 associated X protein(BAX)of myocard in mice with viral myocarditis.Methods Male Balb/c mice were randomly divided into control group,coxsackie viral B3(CVB3)infection group(infection group),IGF-1-treated group in earlier stage(0-6 d)and acute stage(7-13 d),injected IGF-1 of exogenous in abdominal cavity [30 ?g/(kg?d)].Animals were killed at the 14 day.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of BCL-2 and BAX in myocardial tissue.Results In infection group,the expression of BCL-2 reduced and BAX increased than those of control and treatment group(Pa

ObjectiveTo explore effect of interleukin-10 (IL-10) on histopathologic scores of severe acute pancreatitis (SAP) and the level of serum amylase (AMY) in rats.Methods48 female and male adult Sprague Dawley rats (200—300g) were randomly allocated into three groups: OPgroup, SAP group and IL-10 group with 16 rats in each group. SAP was made with retrograde ductal infusion of 5% sodium taurocholate solution.ResultsIn SAP and IL-10 group, there were interstitial edema, necrosis, neutrophil infiltration and interstitial hemorrhage of pancreas, more or less. At 6h and 12h after models were made, the pancreatic histopathologic score in IL-10 group (4.00±0.33 and 6.25±0.25) were significantly lower than that in SAP group (6.13±0.35 and 9.50±0.50)(P<0.01). At 6 h after models were made, the serum AMY in IL-10 group was lower than that in SAP group (P<0.05), but at 12 h there were no differences.ConclusionIn earlier period of SAP in rats, IL-10 can lower the serum AMY level, and significantly reduced pancreatic histologic score (edema, inflammation, hemorrhage, and necrosis).

Objective To assess the clinical factors impacting on the effective time of endocrine therapy for patients with prostate cancer.Methods The chnical data of 432 patients with prostate cancer who accepted endocrine therapy were analyzed retrospectively.The endpoint of the study was failure of endocrine therapy which was defined as continuous elevation of prostate specific antigen (PSA) from nadir for 2 times and more than 0.2 μg/L.The clinical data such as age,clinical stage,lymph node metastasis,bone metastasis,Gleason score,initial PSA,and PSA nadir were collected and their rehtionship with the effective time of endocrine therapy were further assessed via COX regression model.Results Age of onset was 57-88(73.70 ± 7.28) years.Initial PSA was 10.30-588.10(27.15 ± 75.90) μ g/L.The effective time of endocrine therapy was 3-62 (27.01 ± 13.10) months.Univariate regression analysis showed that initial PSA,clinical stage,Gleason score,PSA nadir,lymph node metastasis,bone metastasis were correlated with the effective time of endocrine therapy (P ＜ 0.01).Multivariate regression analysis showed that only Gleason score was correlated with the effective time of endocrine therapy(P=0.001).Compared with patients with Gleason score equal to or less than 3+4,patients with Gleason score equal to or more than 4+3 showed 2.49 fold increased risk of therapy failure (OR =2.49,95％ CI 1.44-4.30).Conclusion Gleason score has close relationship with the effective time of endocrine therapy for patients with prostate cancer,Gleason score equal to or more than 4+3 is an indicator for poor response to endocrine therapy.

Objective To investigate the survival status and pathogens in adult patients with severe community-acquired pneumonia (SCAP) for the past ten years in our hospital. Methods A total of 159 adult patients with SCAP were enrolled for this study from January 2007 to December 2016 in our hospital. Patients were divided into early stage group (from January 2007 to December 2011, n=71) and late stage group (from January 2012 to December 2016, n=88). The clinical data, pathogen distribution and prognosis were compared between two groups. Results (1) The proportion of patients with blood urea nitrogen (BUN) > 7.1 mmol/L was significantly higher in late stage group than that of early stage group (P<0.05). There were no significant differences in baseline data, vital signs, imaging findings and other laboratory examinations between the two groups (P>0.05). (2) For distribution of pathogens, 42 and 49 cases were detected pathogens in early stage group and late stage group. The detection rate of Legionella pneumophila was significantly higher in late stage group than that in early stage group (26.5% vs. 7.1%, P<0.05). (3) For complications, the incidence of septic shock was significantly higher in late stage group than that in the early stage group (22.7%vs. 9.9%, P<0.05). The fatality rate within 30 d after admission was significantly higher in late stage group than that of early stage group (43.2%vs. 25.4%, P<0.05). Results of multi-factor Cox proportional hazard regression analysis showed that septic shock and respiratory acidosis were independent risk factors of mortality in early stage group (P<0.05) while septic shock, chronic obstructive pulmonary disease (COPD) and multi-lobar infiltrates were independent risk factors of mortality in late stage group ( P<0.05). Conclusion In the past ten years, basic clinical characteristics of adult patients with SCAP in our hospital have changed little, but detection rate of legionella has showed increasing trend, and the short-term mortality rate has increased. Whether or not patients are combined with septic shock is a key factor affecting the prognosis.

Objective To evaluate accuracy of cefoxitin disk testing for detecting oxacillin resistance coagulase-negative staphylococci (MRCNS). Methods 139 clinical coagulase-negative staphylococci (CNS) were detected with ID32 STAPH. Cefoxitin disk and oxacillin disk testing were used to detect MRCNS. PBP2a was tested by latex agglutination us a reference method. Results 139 CNS isolates were identified to 8 species: Staphylococcus haemolyticus , S. epidermidis , S. hominis , S. xylosus , S. saprophyticus , S. auricularis , S. simulans and S. warneri. The sensitivity and specificity for cefoxtin disk and oxacillin disk testing were 99.0% vs. 86.0% and 91.7% vs. 74.4%, respectively. One S. epidermidis strain was identified to affect the sensitivity of cefoxitin disk testing. S. xylosus, S. warned, and S. saprophyticus were major species related to the decrease of specificity of cefoxitin disk testing. S. haemolyticus, S. hominis, S. simulans and S. auricularis were major species related to the decrease of sensitivity of oxacillin disk testing. And the decrease of specificity of oxacillin disk testing were mainly related to S. hominis , S. simulans , S. xylosus , S. auricularis , S. saprophyticus and S. warneri. Conclusions The accuracy of MRCNS detection by cefoxitin disk testing is varied due to different CNS species. So it is necessary to test PBP2a or mecA gene according to CNS species, especially for S. xylosus, S. warned and S. saprophyticus.
