Objectives To analyze the clinical and pathological characteristics of gastric submucosal tumors (GSMTs), and evaluate the safety and efficacy of endoscopic treatment for GSMTs. Methods 61 patients with GSMTs were selected from June 2014 to September 2012 by endoscopy and ultrasonography;they were all treated by endoscopic therapy; pathological examination was took in all removed tumors, the tumors which could be the gastric stromal tumor were furtherly examined by molecular biology technique of immunohistochemistry. Result In 61 cas-es, 39 cases are female patients, accounting for 63.93%;the tumors located at the stomach fund accounted for 52.46%(32/61), at the gastric corpus for 21.31%(13/61), at the gastric antrum for 11.48 %(7/61), at cardia for 14.75%(9/61); 10 cases were treated by Endoscopic submucosal dissection, 21 by endoscopic submucosal excavation, 27 by Endoscopic full-thickness resection, 3 by Submucosal tunnelling endoscopic resection; in all 61 cases, 2 were changed to laparoscopic treatment because one tumor was too big and broke the Serous and another was located at mucus Lake of gastric fund, 1 occurred postoperative bleeding and was treated by laparoscopy successfully, 1 oc-curred postoperative perforation and was treated by endoscopy successfully; after pathological and immunohisto-chemical analysis, 34 tumors were identified as gastric stromal tumor and all of them in risk classification were at very low risk, 11 were leiomyoma, 5 were lipoma, 3 were heterotopic pancreas, 5 were calcifying fibrous pseudotu-mor, 2 were inflammatory fibroid polyps, and 1 was angiomatous proliferation; gastric stromal tumor at gastric fundus account for 73.53 % (25/34), at gastric corpus for 11.76 % (4/34), at gastric antrum for 5.88 % (2/34) and at cardia for 8.82 %(3/34). Conclusion Most GSMTs are found in female and commonly lack of specific clinical symptoms;GMSTs are commonly located at gastric fund and most of them are gastric stromal tumors, vast majority of gastric stromal tumors in the risk classification are at very low risk;the endoscopic resection is a mini-invasive, safe and ef-fective treatment for GSMTs.

Fluorescent staining method is a sensitive cytochemical staining method, it can reflect minimal changes of biochemical components of cells. The 7690-Xu fluorescent staining solution prepared with thioflavine can show the heterogeneo- us fluorescence of cells in different stages of differentiation. The younger cells with low degree of differentiation show blue fluorescence, the lower the degree the deeper the color. Along with the differentiation of cells, the blue color of fluorescence deflects to the red color of spectrum gradually, the blue color of fluorescence of cytoplasm changes gradually to bluish, bluish-green, and finally yellow color. The blue color of fluorescence of nucleus changes through greyish- blue to orangeyellow or orange-red.The cytoplasm of cells in various organs with high degree of differentiation appears yellow, and the nucleus orange-yellow or orange-red in color.

Two hundred and four patients with diabetic nephropathy and depressive disorder were randomly assigned to the control group (40 cases), St.John's Wort extract (SWE) group(40 cases) ,SWE +psychotherapy group ( 40 cases), SWE + physicotherapy group ( 40 cases ) and SWE + psychotherapy +physicotherapy group (44 cases), all patients were treated for 12 weeks.The therapeutic effects were evaluated with Hamilton Rating Scale for Depression-17 (HAMD-17).The percentage reduction in HAMD scores in SWE + psychotherapy + physicotherapy group was the highest ( 86% ), and those for SWE, SWE +psychotherapy, SWE + physicotherapy and control groups were 47%, 55%, 60% and 13%, respectively (x2 =47.331, P =0.000).After 12 weeks of treatment, glycosylated hemoglobin(HbA1c) and urinary albumin excretion rate (UAER) were reduced in all 4 treatment groups compared with the control group.The levels of HbA1 c and UAER in SWE + psychotherapy + physicotherapy group were significantly lower than those in others ( F = 15.754,74.025, all P = 0.000).St.John' s Wort extract with psychotherapy and physicotherapy can efficiently improve the depressive disorder in type 2 diabetic patients with nephropathy, as well as control blood glucose and reduce UAER of patients.

Objective To evaluate the in vitro effect of heat shock protein 70(HSP70)on interleukin-6 (IL-6)expression by cultured fibroblasts from psoriasis vulgaris lesions(PFbs).Methods Fibroblasts were isolated from the lesions of patients with psoriasis vulgaris and subjected to a primary culture.After 3 to 5 passages of culture,the fibroblasts were collected and used in the next experiment.Some PFbs were cultured with different concentrations(5,10,20,30 mg/L)of HSP70 for 48 hours,or with HSP70 of 30 mg/L for different durations(3,6,12,24,48,72 hours);some PFbs were incubated with HSP70 of 30 mg/L for 24 hours after pretreatment with pyrrolidine dithiocarbamate(PDTC,a specific inhibitor of nuclear factor-kappa B)for 30 minutes.PFbs receiving no treatment served as the control.Enzyme-linked immunosorbent assay(ELISA)and semi-quantitative reverse transcription PCR were performed to measure the IL-6 protein expression in culture supematant and IL-6 mRNA expression by PFbs,respectively.Differences in the expression of IL-6 protein and mRNA between PFbs receiving different treatment were analyzed by using t test and Dunnett's t test.Results HSP70 significantly increased both protein production and mRNA expression of IL-6 in a time(0-48 h)-and dose(5-30 mg/L)-dependent manner.The expression levels of supernatant IL-6 protein and IL-6 mRNA were significantly higher in the PFbs treated with HSP70 of 10 mg/L for 48 hours than untreated PFbs((75.2 ± 15.4)ng/L vs.(47.2 ± 10.6)ng/L,0.439 ± 0.093 vs.0.249 ± 0.069,both P ＜ 0.05).A significant increase was observed as early as 6 hours in the level of IL-6 mRNA after the treatment with HSP70 of 30 mg/L,and 12 hours in the level of supematant IL-6 protein.Decreased supernatant IL-6 protein and IL-6 mRNA were noted for PFbs treated with PDTC and HSP70 of 30 mg/L compared with untreated PFbs((42.23 ± 9.41)ng/L vs.(68.40 ± 14.43)ng/L,0.144 ± 0.048 vs.0.295 ± 0.081,both P ＜ 0.05).Conclusion HSP70 may increase the expression of IL-6 mRNA and protein by cultured PFbs via the nuclear factor-kappa B pathway.

Objective To observe the level of serum hepatocyte growth factor (HGF) in patients with impaired glucose tolerance (IGT). Methods Thirty patients with IGT (IGT group), 30 patients with type 2 diabetes mellitns (T2DM) (T2DM group) and 30 healthy controls (control group) were recruited for this study. Such indexes as HGF, fasting plasma glucose (FBG), postprandial plasma glucose (2hPG), glycosylated hemoglobin A1c( GHbA1c ), fasting insulin(FINS), systolic blood pressure(SBP), diastolic blood pressure (DBP) were examined and these related factors were analyzed. Results The levels of serum HGF in IGT group and T2DM group were higher than those in control group [(413.22 ± 102.48), (422.76 ± 126.77 ), ( 120.45 ± 25.11 ) ng/L, respectively ] (P < 0.05 ). There was no significant different between IGT group and T2DM group (P> 0.05). There was positive correlation between HGF and FBG (r = 0.326, P< 0.05 ). Multiple regression analysis indicated significant correlation between HGF and DBP (r = 4.730, P< 0.05). Conclusion Higher levels of HGF are found in IGT patients, which indicates that function of vascular endothelium is abnormal in this period.

Objective To observe the level of serum hepatocyte growth factor(HGF)in patients with hypertension(HT).Methods HGF,fasting plasma glucose(FBG),postprandial plasma glucose(2hPG),glycosylated hemoglobin A1c(HbA1c),total cholesterol(TC),triglyceride(TG),systolic blood pressure(SBP),diastolic blood pressure(DBP),body mass index(BMI)and waistline(w)were detected in 30 patients with hypertension,30 patients with hypertension complicated by type 2 diabetes mellitus(T2DM),and 30 normal controls such indexes as.Results The level of serum HGF in HT group[(413.87±90.87)ng/L],and HT+T2DM group[(413.72±98.72)ng/L]were higher than that in control group[(120.45±25.11)ng/L](P＜0.05),but there was no significance between HT group and HT+T2DM group(P＞0.05).There existed a positive correlation between HGF and FBG,SBP(r=2.273,r=5.353,P＜0.05).Conclusion Higher levels of HGF is found in patients with hypertension and hypertensin complicated with T2DM,which indicates the severity of dysfunction of vascular endothelium.
