Objective To investigate the clinical efficacy of conventional treatment combined with flupentixol and melitracen in patients with reflux esophagitis (RE).Methods From June 2012 to March 2015, a total of 182 patients were selected as study subjects from newly diagnosed RE patients.The anxiety and depression scores were evaluated according to Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD).And then patients were divided into HAMA and HAMD negative conventional treatment group and combined treatment group, HAMA and HAMD positive conventional treatment group and combined treatment group.Rabeprazole and mosapride were administrated in conventional treatment group.For patients in combined treatment group, on the base of conventional treatment flupentixol and melitracen were added.The treatment course was eight weeks.The degree of anxiety and depression, RE symptoms and mucosal healing under gastroscope were evaluated before and after treatment.Adverse drug reaction was observed.Chi square test or t test was performed for statistical analysis.Results Eight weeks after treatment, the scores of HAMA and HAMD in HAMA and HAMD positive combined treatment group were 7.930 ±3.832 and 9.630 ± 3.650, which were both lower than those of conventional treatment group (11.660 ± 4.108 and 12.170 ± 4.459), and the differences were statistically significant (t=3.683 and 2.233;both P＜0.05).The symptom scores of heartburn, regurgitation, chest pain of HAMA and HAMD positive combined treatment group were 0.700±0.591,0.780± 0.629 and 0.720±0.621, respectively, which were lower than those of conventional treatment group (1.280 ± 0.502, 1.370 ± 0.610 and 1.040 ± 0.842), and the differences were statistically significant (t =5.133, 4.413 and 2.114, all P＜0.05).There were no statistical significance in symptoms scores between HAMA and HAMD negative combined treatment group and conventional treatment group (all P＞0.05).After treatment, the mucosal healing rate of HAMA and HAMD positive combined treatment group was 91.3％ (42/46), which was higher than that of conventional treatment group (71.7 ％, 33/46), and the difference was statistically significant (x2 =5.845, P =0.016).The incidence of adverse events of HAMA and HAMD negative combined treatment group was 4.8％ (2/42), and that of HAMA and HAMD positive combined treatment group was 2.2％(1/46).Conclusions The conventional treatment combined with flupentixol and melitracen in RE patients accompanied with anxiety and depression was remarkable and safe.RE patients without obvious anxiety or depression, preventive use of antianxiety and antidepressant medicine can not improve the efficacy.

Objective To evaluate the efficacy and safety of endoscopic therapy in the treatment of symptomatic pancreatic divisum (PD).Methods Data of 8 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with the diagnosis of pancreas divisum at our institution from June 2006 to June 2013 was retrospectively analyzed.Results The patients were identified as pancreatic divisum with 28 ERCP procedures.All patients received stent placement,7 underwent minor papilla sphincterotomy,6 pancreatic duct stricture dilatation,and 1 stone extraction.Post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in 1 patient,and no other complications occurred.After a follow-up of 2-47 months,1 patient died of pancreatic carcinoma,3 patients removed the stents,3 patients were followed up regularly,and 1 was unavailable for the interview.The episode of chronic pancreatitis and the extent of abdominal pain decreased after the operations.Conclusion Endoscopic therapy is effective and safe for the pancreatic divisum patients.It can reduce the episode of chronic pancreatitis and relieve the chronic abdominal pain in PD patients with low incidence of complication.

Objective To compare the efficacy of stents 7 F and 10 F in drainage of pancreatic pseudocyst via EUS-FNA.Methods A retrospective analysis of patients with pancreatic pseudocyst who received endoscopic ultrasonography guided puncture drainage by using 7 F and 10 F double pigtail plastic stent respectively in Drum Tower Hospital of Nanjing University Medical School from 2010 to 2014 was conducted.Patients' hospitalization period, the time for 50％ cyst reduction, removal time, infection rate, and recurrence rate were compared.Results Twenty three patients with pancreatic pseudocyst were included, among whom 14 were male and 9 were female.The age ranged from 13 to 70 with an average of 45.1 years.Eleven patients were treated with 7 F pigtail plastic stents whereas 12 patients with 10 F pigtail plastic stents.All patients were treated with additional 8.5 F joint nose cyst drainage.Four cases in 7 F group got fever, 3 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (9.1％) relapsed without symptoms after 52 months during the follow-up and received no intervention.Five cases in 10 F group got fever, 4 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (8.3％) was identified as mild hemorrhage, and replantation needed to be performed in 1 case (8.3％) because stent was found to slip after 12 days.Two cases (16.7％) relapsed without symptoms after 11 and 24 months respectively and no intervention was received.There was no significant difference in patients' age, cyst size, removal time, infection rate and recurrence rate between the two groups.However, patients in group 10 F had a markedly shorter hospitalization period and time for cyst reduction by at least 50％ than those in group 7 F (P ＜ 0.05).Conclusion 10 F double pigtail plastic stents can drain the cyst faster, shorten the hospital stay, but there is no significant difference in infection or recurrence rate of cyst compared with 7 F stents.

Objective To analyze the clinical features of patients with IgG4-associated biliary and pancreatic diseases,and to improve the understanding of these diseases.Methods Nine cases of patients with IgG4-associated pancreatitis and cholangitis were analyzed retrospectively,which included clinical manifestations,serological examination,imaging test,pathology,treatment and prognosis.Results Of the 9 patients,8 were male,1 was female,the average age was 61 years old.Four cases were presented with jaundice,2 cases with jaundice and abdominal pain,2 cases with abdominal pain,and 1 case with diabetes.Serum IgG4 levels were 3.46-21.3 g/L (mean 9.743 g/L) in 6 cases,and which were higher than normal value,3 patients did not undergo blood test of IgG4.Nineteen auto-antibodies (including ANCA) were all negative in 9 cases.CA19-9 was increased in 4 cases.CT manifestations showed 5 cases with low density pancreas mass (2 cases with biliary tract dilatation);1 case had pancreas swelling with dilatation of bile duct,and 2 cases with bile duct dilatation only,and CT findings in 1 case were negative.Four patients underwent EUS-FNA,and EUS features included hypoechoic lesions without peripancreatic lymph nodes.FNA results indicated 2 cases with IgG4 related chronic inflammation,2 cases with chronic inflammation with negative IgG4.Seven cases were confirmed to have IgG4 related pancreatitis,and 2 cases with IgG4 related cholangitis.Six patients received glucocorticoid treatment,and the dose ranged from 8-40 mg;3 patients underwent surgery and the surgical pathology indicated IgG4 positive plasma cell.Follow-up showed the serum IgG4 returned to normal,clinical symptoms improved remarkably,and pancreatic mass decreased.Conclusions IgG4 positive plasma cell infiltration is the main feature of IgG4-associated cholangitis and pancreatitis.The diagnosis should combine image,serology with pathology.Glucocorticoid is an effective treatment.

Objective To summarize the clinical symptoms of patients with non-erosive reflux disease(NERD) and reflux esophagitis(RE),which is helpful to the differential diagnosis.Methods Outpatients who met the criteria of NERD or RE according to the Montreal definition in Gastroenterology Department Wuhan Union Hospital from 2010-2014 were enrolled in our study.Clinical data were comprehensively collected.Incidence of disease,severity,frequency of esophageal and extraesophageal symptoms,and the rates of overlapping with functional dyspepsia (FD) or irritable bowel syndrome (IBS) were all studied.Results Totally 446 subjects were recruited,including 225 patients with NERD and 221patients with RE.The occurrence rates of esophageal symptoms including heartburn [76.0％ (171/225) vs 52.0％ (115/221),P ＜ 0.01] and acid regurgitation [74.7％ (168/225) vs 54.3％ (120/221),P ＜0.05] in NERD group were significantly higher than those in RE patients,with more severe and frequent (P ＜ 0.05).Despite the rates of food regurgitation were similar,NERD patients behaved more severely and frequently (P ＜ 0.05).Extraesophageal symptoms including throat burning and foreign body sensation in NERD group [40.9％ (92/225) vs 27.6％ (61/221),42.2％ (95/225) vs 31.7％ (70/221),all P ＜0.05] were also higher than those in RE group,the degree of which was more severe too (P ＜ 0.05).RE patients claimed a higher proportion of chronic cough.The incidences of overlapping with IBS in two groups were similar.But there were more patients with FD in NERD group [72.0％ (162/225) vs 62.9％ (139/221),P ＜ 0.05] than in RE group.Conclusions The menifestations and degree of esophageal and extraesophageal symptoms in patients with NERD or RE are different,as well as comorbidities such as FD and IBS.These results suggest that NERD and RE are independent diseases.

Systemic inflammatory response syndrome (SIRS) is a pathophysiological process of critical children.It's pathogenesis involved many sides such as immune dysfunction,gene expression regulation and intestinal barrier.By studying the regulation mechanism of SIRS,early diagnosis of SIRS can be made.According to the inflammatory status and each sides of pathogenesis,effective control results can be taken in time to stop the further developmentof SIRS and improve outcomes of critical children.

Objective To investigate the diagnostic value of intraductal ultrasonography (IDUS) and bile tumor marker in differential diagnosis of suspected biliary stricture.Methods A total of 57 patients with biliary stricture (8 benign strictures,49 cases of malignant strictures),who underwent IDUS and tests of serum and bile tumor markers (CA19-9 and CEA),were analyzed.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy were compared among the outcomes of B-ultrasonography,CT,MRCP,IDUS,as well as IDUS combined with bile tumor markers.Results The specificity of the IDUS and the combined group were 63.6％ (7/11) and 77.8％ (7/9) respectively (P ＞ 0.05).The positive predictive value of the IDUS and the combined group were 91.8％ (45/49) and 95.9％ (47/49) respectively (P ＞0.05).The diagnostic accuracy of the IDUS and the combined group were 91.2％ (52/57) and 94.7％ (54/57) respectively (P ＞0.05).Data of the two groups were significantly higher than conventional imaging like B-ultrasound,CT and MRCP.The accuracy of IDUS combined with bile CEA for the diagnosis of distal bile duct cancer was 97.9％ (46/47),significantly higher than that of IDUS.Conclusion IDUS combined with biliary tumor markers is of high value for distinguishing the bile benign from malignant stricture.IDUS combined with biliary CEA test can improve the diagnostic accuracy of distal malignant biliary stricture diseases.

This article was aimed to study the inhibitory effect of ginseng polysaccharide injection on tumor growth a-mong ICR mice after inoculation of S180 cells, and its immune mechanism as well as its synergic effect in reducing toxicity of cytoxan (CTX). The experiment was carried out in ICR mice after inoculation of S180 cells. The mice were randomly divided into the model group, the control group, the CTX group, and the drug combination group. After 10 days of medication, the inhibition of tumor growth, WBC, thymus index and spleen index were measured in mice dur-ing the experiment. The immunodepressed mice model was induced by CTX. Effects of ginseng polysaccharide injec-tion on serum hemolysin and monomuclear macrophage phagocytosis were evaluated. The results showed that the com-bination of ginseng polysaccharide injection and CTX can significantly increase the tumor inhibiting rate. It can also reduce the side effect and toxicity of CTX, which may improve the immunosuppression induced by CTX. It was con-cluded that ginseng polysaccharide injection can increase the therapeutic effects and reduce the toxicity of CTX.

Objective To investigate the influence of FOXP 3 expression in pancreatic carcinoma cells (PCCs) on the maturation and immunologic function of dendritic cells (DCs).Methods The siRNA sequences targeting FOXP3 gene (siRNA-FOXP3) and negative control siRNA (siRNA-NC) were specifically designed and transfected into PCCs , then the level of IL-10 and TGF-β1 of culture supernatant were detected by ELISA.The supernatants of pancreatic carcinoma cell transfected by FOXP 3-siRNA were collected , then it was mixed with GM-CSF and IL-4 to induce the differentiation of DCs .Flow cytometric analysis were used to measure the expression of surface markers CD 86 , CD80 , HLA DR on DCs which were treated with supernatants . The levels of IL-12p70, IFN-γin supernatants were detected by ELISA .The DCs were co-cultured with T lymphocytes, and then the lymphocytes proliferation and cytoxicity were analyzed by CCK -8 assays.Results Compared with PANC1 with siRNA-NC transfection, PANC1 with siRNA-FOXP3 transfection had a decreased expression of IL-10, TGF-β1 [(8.93 ±3.06)ng/L vs (26.60 ±5.57)ng/L;(2 544 ±78)ng/L vs (2 856 ± 92)ng/L], the positive expression rate of CD86, HLA DR in DCs cultured in the medium containing the supernatants of the pancreatic carcinoma cell transfected by siRNA-FOXP3 was significantly increased [(28.10 ±3.11)%vs (13.90 ±0.42)%;(66.15 ±4.17)%vs (43.15 ±3.32)%], the expression of IL-12p70, IFN-γwas significantly increased [(52.75 ±7.89)ng/L vs (26.14 ±4.50)ng/L, (898.43 ±88.82) ng/L vs (412.76 ±24.68) ng/L], after co-culture with lymphocytes at ratios of 1:5, 1:10, 1:20, the proliferation was significantly increased [(95.27 ±3.80)% vs (71.77 ±5.70)%, (78.97 ±5.73)% vs (52.30 ±8.72)%, (57.60 ±4.36)% vs (43.73 ±6.01)%], and the cytoxicity of CTL to PANC1 cells with 1:20, 1:40 co-culture was significantly increased [(28.44 ±5.20)% vs (8.82 ±2.29)%, (40.85 ± 5.15)% vs (17.38 ±4.86)%], and the difference between the two groups was statistically significant (P<0.05).Conclusions FOXP3 expression in PCCs can inhibit the maturation and immunologic function of DCs.
