Objective To explore the effects of psychological disorders on qualityoflife of elderly patients with non-erosive reflux disease (NERD) under maintenance treatment of proton pump inhibitors (PPIs). Methods A total of 76 elderly patients with NERD treated by proton pump inhibitors (maintenance treatment of Esomeprazole over half a year) were enrolled. They were classified into symptom group aged (66.5±8.2) years (n=35) and symptom group aged(68.2+6.9)years (n=41)according to reflux symptoms,with 20 healthy people aged(65.4 ±8.8)years as control.The subjects completed the questioniaires on psychological status including self-rating anxiety scale (SAS) and self-rating depression scale (SDS) and their quality of life was evaluated by gastroesophageal heath related quality-of-life instrument(GERD -HRQL) and medical outcomes study short form(SF-36). Results Scores of SAS and SDS were significantly higher in symptom group (54.9±6.2,57.9±8.6) than in symptomless(37.9±8.7,42.7±7.9) and health control group (38.9± 7.2,43.1 ± 8.9),all (P<0.05),but there was no difference between symptomless and health control group.The rates of anxiety and depression in symptom group (51.4%,57.1%) were increased as compared with symptomless (12.2%,9.8%)and health control group(0.0%,5.0%).Scores of GERD HRQL in symptom group were higher than in symptomlcss group (21.4± 5.0 vs.4.5±2.2,t=19.76,P<0.01)while the indexes such as body pain,vitality,social function,affection,mental and whole health in score of SF-36 besides physiology function were lower in symptom group than in symptomless and control groups (P<0.05 or P<0.01 ).Only the significant differences in mental and whole health of SF-36 were found between symptomless and control groups (P<0.01).Correlation analysis revealed that SAS and SDS scores were positively correlated with scores of GERD-HRQL in symptom group(P<0.01) and negatively with all dimensions of SF-36 but physical function (P< 0.05). Conclusions Most of elderly symptomatic patients with NERD treated by PPI are in psychological disorders which results in lower quality of life.

OBJECTIVETo explore the clinical effects of negative pressure wound therapy (NPWT) combined with artificial dermis grafting and autologous skin grafting on repair of open joint wounds and/or wounds with exposed bone fracture.
METHODSEleven patients with open joint wounds and/or wounds with exposed bone fracture, hospitalized from November 2008 to November 2014, were enrolled in the study. According to the differences of the first stage treatment, all patients were divided into experimental group ( n = 6, including 4 patients of open joint wounds, 1 patient of wound with exposed bone fracture, and 1 patient of open joint wound with exposed bone fracture), and control group ( n 5, including 2 patients of open joint wounds, 2 patients of wounds with exposed bone fracture, and 1 patient of open joint wound with exposed bone fracture). After debridement, the wounds in both groups were grafted with punctured artificial dermis, while NPWT was only used over the artificial dermis of experiment group for 1 week. In the operation at sacsod stage, autologous split-thickness skin was grafted on the vascularized artificial dermis in both groups. Results In 5 patients of open joint wounds in experimental group, the artificial dermis was vascularized well, autologous skin grafts survived, and wounds were healed. In 3 patients of open joint wounds in control group, the artificial dermis grafting all failed due to local infection, and then these wounds were repaired with local tissue flap grafting. Artificial dermis in 3 patients of wounds with exposed bone fracture in both groups was vascularized well after grafting, and the wounds were healed after autologous skin grafting, whether or not NPWT was used.
CONCLUSIONSNPWT combined with artificial dermis grafting and autolognus skin grafting can be used for repairing open joint wounds and/or wounds with exposed bone fracture.

OBJECTIVE:To study the ADR mechanism of conjunctival hyperemia in model rats with prostacyclin-induced high intraocular pressure. METHODS:50 rats were randomly divided into normal control group,model group,prostacyclin low-dose, medium-dose,high-dose groups(100,200,400 mg/kg),10 in each group. Except for normal control group,right eyes of rats in other groups were established high intraocular pressure model,dropping corresponding medicine once a day,for 1 week. After last administration,the right eyes cornel peripheral corneal endothelial cells of rats in each group were isolated in vitro and cultured. Vascular endothelial cell viability,cell apoptosis and proliferation-related factor(Ki-76),apoptosis-related factors(Bad,Bax),in-hibito of apoptosis-related factors (Bcl-2,Bcl-xl) protein expressions were detected. RESULTS:Compared with normal control group,vascular endothelial cell viability in model group were obviously decreased;apoptosis rate was obviously increased;Bad, Bax protein expressions were obviously enhanced;Bcl-2,Bcl-xl,Ki-76 protein expressions were obviously weakened,with statisti-cal significances (P<0.05 or P<0.01). Compared with model group,vascular endothelial cell viability in prostacyclin low-dose,medium-dose,high-dose groups were obviously decreased;apoptosis rate was obviously increased;Bcl-2,Bcl-xl protein expres-sions were obviously weakened,with statistical significances(P<0.05 or P<0.01);the Bad,Bax protein expressions in prostacy-clin medium-dose,high-dose groups were obviously enhanced(P<0.05 or P<0.01),the other indexes had no statistical differenc-es(P>0.05). CONCLUSIONS:Prostacyclin may cause conjunctival hyperemia through promoting the apoptosis of cornel peripher-al corneal endothelial cells of model rats with high intraocular pressure and decreasing the cell viability.

Objective To study the roles of apoptosis genes bcl 2, bax, and bak in the pathogenesis of hepatitis D. Methods Expressions of HDAg, bcl 2, bax, and bak in liver specimens of 77 patients with hepatitis D were studied by immunohistochemical method. Meanwhile, the relationship of HDAg expression with the expressions of bcl 2, bax, and bak was studied by double labelling. Results Bcl 2 was mainly expressed in the cytoplasm of hepatocytes, and bax and bak mainly in the cytoplasm of hepatocytes and partly in the nucleus of hepatocytes, and HDAg mainly in the nucleus of hepatocytes. Lots of HDAg and bax/bak positive cells were distributed in infiltrating lymphocytes at the periportal region especially at the advancing edges of areas of piecemeal necrosis. Apoptosis of many hepatocytes was found to locate near the HDAg positive cells. There was positive correlation between the expression of bax/bak and HDAg expression ( P

Objective To study the inhibitory effect on the expression of regulated upon activation,normal T cell expressed and secreted (RANTES) and monocyte ehemotactic activity of ectopic endometrial stromal cells by nuclear factor(NF)-kB decoy oligonucleotides (ODN). Methods The stromal cells of ectopic endometrium were divided into 3 groups. Two groups were cultured with or without 10 μg/L of interleukin (IL)-1β. Another group was transfected with NF-kB decoy ODN with the aid of a lipofectamine reagent. After 4 h of transfection, 10 μg/L of IL-1β was added to induce the stromal cells to secrete RANTES. Concentration of RANTES in the supernatant at 4, 8, 12, 24 and 36 h was measured with the sandwich enzyme linked immunosorbent assay (ELISA). U937 monocyte chemotactic activity was assayed in Boyden chambers. The specific RANTES-neutralizing monoclonal antibodies at serial doses (0. 5, 1, 2, 4and 8 mg/L) were added into IL-1β induced medium of 24 h to detect the monocyte chemotactic activity of RANTES in supernatant. Results The concentration of RANTES secreted by stromal cells was respectively (58 ± 10), ( 150 ± 35 ), ( 360 ± 46 ) and ( 586 ± 42 ) ng/L after IL-1β stimulation for 8,12,24 and 36 h,significantly higher than that of stromal cells cultured without IL-1β. The concentrations of RANTES were respectively (86±16), ( 128±28 ) and ( 183±32) ng/L after IL-1β stimulation for 12, 24 and 36 h in stromal cells transfected with NF-kB decoy ODN, evidently lower than that of stromal cells stimulated with IL-1β alone. The monocyte ehemotactic index of 12, 24, 36 h in conditioned medium of stromal cells transfected with NF-kB decoy ODN was respectively 10. 3 ± 0. 9, 13.7 ± 1.1, 18.6 ± 1.2, which was evidently lower than that of stromal cells stimulated with IL-1β alone. The anti-RANTES antibody at 0. 5, 1,2, 4 and 8 mg/L inhibited respectively 5%, 23%, 40%, 62% and 61% of the chemotactic activity in 12 h medium treated with IL-1β. Conclusions RANTES accounts for the majority of the monocyte chemotactic activity in IL-1β induced medium of 24 h. NF-kB decoy ODN may influence the feed-forward inflammatory loop whereby IL-1β from activated macrophages can lead to RANTES production by ectopic implants and further monocyte chemotaxis.

Objective To investigate the risk factors of standard selectivity biliary cannulation in endoscopic retrograde cholangiopancreatography (ERCP) for patints with choledocholithiasis,and the effect and safety of assistant cannulation methods.Methods The clinical data were retrospectively analyzed in 372 patients,who received ERCP for choledocholithiasis in the Yijishan Hospital of Wannan Medical College from January 2014 to December 2014.The risk factors of standard biliary cannulation were assessed by univariate and multivariate logistic regression analysis.The success rate of assistant biliary cannulation and the incidence of post-ERCP pancreatitis (PEP) of standard biliary cannulation were compared with doubleguide wire technique (DGT) and precut sphincterotomy (PS),which were used when standard biliary cannulation failed.Results The univariate analysis showed that floppy and long duodenal papilla (P=0.000),angulated common bile duct(P=0.013) were related to failure of standard biliary cannulation.Multivariate analysis showed that floppy and long papilla (P=0.000,OR=0.131,95%CI:0.056-0.307),angulated common bile duct (P =0.003,OR =0.378,95 % CI:0.197-0.726) were independent risk factors for standard biliary cannulation.The success rate of standard biliary cannulation was 83.3% (310/372),62 cases undergone DGT or PS after standard biliary cannulation failure,and the total success rate of cannulation was 99.7% (371/372).There were 29 cases suffered from PEP in 371 successful cases of biliary cannulation,including 18 cases (5.8%,18/310) of standard biliary cannulation,8 cases (16.3%,8/49) of DGT,and 3 cases (25.0%,3/12) of PS.The incidence of PEP by DGT (x2 =5.532,P =0.019) and PS (x2 =6.994,P=0.008) was significantly higher than that of standard biliary cannulation,but there was no statistical difference on the incidence of PEP between DGT and PS (x2 =0.079,P =0.778).Conclusion Floppy and long duodenal papilla and angulated common bile duct could easily induce the failure of standard biliary cannulation in ERCP for patients with choledocholithiasis.DGT and PS are effective assistant cannulation methods when the standard cannulation fails.
