Objective To evaluate the effectiveness of biofeedback in preventing chronic daily headaches. Methods One hundred patients experiencing daily headaches were randomly divided into a biofeedback group ( n=50) and a drug therapy group (n=50). The patients in the drug therapy groupwere administered a predetermined course of medication. Those in the biofeedback group were given 30 minutes of biofeedback therapy twice a week for 8 weeks, followed by 10 months of intensive therapy once a month. The headache frequency, duration of headache at-tacks, days of using acute pain medication and any other adverse events were recorded 3, 6 and 12 months after the treatment. Results The patients in the biofeedback group had significantly less-frequent headaches, shorter headache attacks and fewer days of using acute pain medications. Conclusion Compared to drug therapy, biofeed-back can prevent chronic daily headachesmore safely and effectively.

Objective To investigate the effect of intravenous fluid infusion combined with water throuth gastrointestinal tract in treating the patients with hyperosmolar hyperglycemic state(HHS).Methods 30 HHS pa- tients were recruited.All the patients were given water throuth gastrointestinal infusion while they were administrat- ed continuously intravenous infusion.Laboratory parameters such as serum natrium,serum potasium,serum glucose and serum osmolarity ect were monitored at the admission and after treatment.Results Serum glucose and serum osmolarity of HHS patients were decreased smoothly at the speed of less than 3 mmol?L~(-1).h~(-1)during the first 12 hours after treatment.After 48 hour-treatment,serum natrium,serum potassium and serum osmolarity recovered to normal levels except 2 deaths,serum glucose decreased to(10.8?5.2)mmol/L.Conclusion Intravenous fluid infu- sion combined with water throuth gastrointestinal tract for the patients could lower smoothly serum glucose and serum osmolarity and decrease the mortality of the HHS patients.

Background The proliferation and migration of vascular endothelial cells is a primary link during angiogenesis.Studies showed that heat shock protein B6 (HspB6) promotes the secretion of multiple angiogenesis-related factors and therefore leads to neovascularization.Understanding the effects of neutralizing HspB6 antibody on the biological behavior of human choroidal vascular endothelial cells has an important significance in the target treatment of choroidal neovacularization diseases.Objective This study was to address the role and mechanism of neutralizing HspB6 antibody in tube formation of human choroidal vascular endothelial cells.Methods Human choroidal vascular endothelial cell line was normally cultured and harvested for total RNA extraction.Expressions of HspB6 mRNA and protein in human choroidal vascular endothelial cells were detected by reverse transcription PCR (RT-PCR) and flow cytometry (FCM).The cells were seeded on 96-well plate covered with matrigel at the density of 2×104/hole.Then the neutralizing HspB6 antibody at the concentration of 100 μg/Land 500 μg/L was added into the medium respectively,and the control cells were set without the addition of HspB6 antibody.The number of capillary tubes was calculated 12 hours after culture by three-dimensional matrigel assay.In addition,0,50,100,500 μg/L of neutralizing HspB6 antibody were added into the cell medium separately for 24hours,cell counting kit-8 (CCK-8) method was employed to assay the inhibitory rate(IR) of the cells.Transwell test was used to count the cell number across chamber membrane for the evaluation of migration ability of the cells.The apoptosis of the cells was assayed by FCM.Results Both HspB6 mRNA and protein were expressed on human choroidal vascular endothelial cells.The number of capillary tube formation of human choroidal vascular endothelial cells was (67.25±5.75),(60.39±6.41) and (39.76±10.73) /field in the 0,100 and 500 μg/L neutralizing HspB6 antibody groups,with significant difference among them (F =10.210,P =0.012),and the tube number was significantly less in the 500 μg/L neutralizing HspB6 antibody group compared with 0 μg/L neutralizing HspB6 group (P =0.005).The IR of neutralizing HspB6 antibody to the cellular proliferation and migration was enhanced with the increases of concentration and time lapse(Fconcentration =7.485,P =0.002 ; Ftime =16.684,P =0.001).The number of the cells through Transwell chamber membrane was 14.0 ± 2.5,11.1 ± 0.8,6.6 ± 0.1,6.7 ± 0.2 in the 0,50,100,500 μg/L neutralizing HspB6 antibody group respectively,and that in the 100 μg/L and 500 μg/L neutralizing HspB6 antibody group was lessened in comparison with the 0 μg/L neutralizing HspB6 antibody group(both at P=0.000).The apoptosis rate of the cells was (22.73 ± 2.53)％ in the neutralizing HspB6 antibody group,which was significantly lower than (13.33±2.08) ％ of the control group (t=4.967,P=0.008).Conclusions Neutralizing HspB6 antibody inhibits capillary tube formation of human choroidal endothelial cells in vitro in dose-and timedependent manner,probably through suppressing the proliferation and migration and promoting the apoptosis of choroidal endothelial cells.

Objective Excision repair cross-complementing gene-1(ERCC1) are key regulatory enzymes whose expression patterns are associated with overall survival(OS) in several malignancies.Their expression patterns and prognostic value in resected gastric adenocarcinoma(GAC) are not known and need to investigate.Methods A total of 109 patients who underwent resection for GAC in Liu′an People′s Hospital from January 2010 to June 2013 had tissue available for analysis.The primary objective was to assess for the differential expression of ERCC1 using by immunohistochemistry.The secondary objective was to assess for the association between OS and the expression of ERCC1.Results The median follow-up was 21.2 months,and the median OS was 28.8 months.Resected GAC exhibited differential expression of ERCC1(high expression,n=25(23%)).ERCC1 expression was not associated with OS(18.9 months vs.27.7 months,P=0.72).In a subset analysis of patients who received chemotherapy(n=73),high ERCC1 expression was associated with decreased OS(16.7 months vs.53.8 months,P=0.03).After controlling for known adverse pathologic features,high ERCC1 expression persisted as a negative prognostic factor in multivariate Cox regression analysis(HR=2.22,95% CI1.05-4.98,P<0.05).Conversely,in patients who underwent resection only(n=35),high ERCC1 expression demonstrated a trend toward improved OS(40.4 months vs.12.7 months,P=0.10).A positive prognostic influence also was present on multivariate analysis(HR=0.20,95% CI0.05-0.84,P=0.03).Conclusion Resected GAC exhibited differential expression of ERCC1.Among all patients,ERCC1 expression levels were not associated with OS.High ERCC1 tumor expression is associated with decreased OS in the patients who received chemotherapy but is associated with increased OS in those who underwent surgery alone.ERCC1 expression have prognostic value in resected gastric cancer,and further investigation is needed.

Objective To investigate the efficiency of Trichostatin A (TSA) in inducing cell apoptosis and altering the Notch pathway genes expression in PANC-1 cells line.Methods The survival rate and apoptosis of PANC-1 cells were measured by MTT assay and Hoechst 33258 staining,respectively.mRNA expression levels of the genes,numb,gcn512,dll3,hes6,eaf2,cytohesins,in PANC-1 cells were assessed by real-time quantitive PCR.Western blot was used to measure the expression of bcl-2,bax,actived caspase-3 and NICD protein which was the biologically active form of Notch-1.Results After culturing with 0.1,0.2,and 0.4 μmol/L TSA for 24 hours,the cellular survival rate of PANC-1 cells significantly decreased to 72％,58％ and 39％,respectively.The survival rate of PANC-1 was negatively correlated to time length of culture with TSA.Increased apoptosis of PANC-1 cells after 12,24 and 36 h culture with TSA was detected by Hoechst 33258 staining.Western blotting showed that the expression of bax,actived caspase-3 and NICD protein increased while the bcl-2 protein decreased after culture with TSA.In real time quantitive PCR assessment,the mRNA expression of numb and hes6 in PANC-1 cells were upregulated by TSA (P ＜ 0.05),while the mRNA expression of gcn512 and dll3 were down-regulated by TSA (P ＜ 0.05).While mRNA expressions of eaf2 and cytohesin1,2,3,4 were not affected by TSA.Conclusions TSA induces apoptosis of pancreatic cancer cell line PANC-1.The Notch signal pathway may be involved in inducing cellular apoptosis of PANC-1 when cultured with TSA.

Background:X-linked inhibitor of apoptosis (XIAP) is a vital factor in the anti-apoptosis mechanism of tumors and is highly expressed in renal cell carcinoma (RCC).However,the mechanism through which XIAP regulates DNA damage repair is unknown.This study investigated the regulatory mechanism of XIAP in etoposide-induced apoptosis in two Caki-1 cell lines with high or low XIAP expression.Methods:The two cell lines were established using RNA interference technology.The differentially expressed proteins in the two cell lines were globally analyzed through an isobaric tags for relative and absolute quantitation-based quantitative proteomics approach.Proteomic analysis revealed 255,375,362,and 5 differentially expressed proteins after 0,0.5,3,and 12 h of drug stimulation,respectively,between the two cell lines.The identified differentially expressed proteins were involved in numerous biological processes.In addition,the expression of histone proteins (H1.4,H2AX,H3.1,H3.2,and H3.3) was drastically altered,and the effects of XIAP silencing were accompanied by the marked downregulation of H2AX.Protein-protein interactions were assessed and confirmed through immunofluorescence and Western blot analyses.Results:The results suggested that XIAP may act as a vital cell signal regulator that regulates the expression of DNA repair-related proteins,such as H2AX,and influences the DNA repair process.Conclusions:Given these functions,XIAP may be the decisive factor in determining the sensitivity of RCC cell apoptosis induction in response to chemotherapeutic agents.

Objective To investigate the features and correlation analysis of clinico-pathological and expression of phospholipase A2 receptor(PLA2R)in idiopathic membranous nephropathy. Methods A number of 244 patients of IMN proved by renal biopsy were recruited in Wuxi People's Hospital from July 2008 to February 2015. Data were restrospectively collected. Results In the 244 IMN patients(mean age 54.07 ± 15.22 years,130 males and 114 females),44.3% had hypertension and 62.7% had nephrotic syndrome. Compared with female patients ,male patients had more severe proteinuria and lower eGFR(P < 0.05). Compared with the group of proteinuria < 4 g/24 h,the groups of proteinuria 4~8 g/24 h and > 8 g/24 h had higher level of cholesterol and blood pressure ,lower eGFR and more severe tubulointerstitial lesions(P < 0.05). Pathological stage Ⅰ and Ⅱaccounted for 98%,and there were more severe tubulointerstitial lesions and lower eGFR in the patients of stage Ⅱthan that in the patients of stageⅠandⅠ~Ⅱ(P<0.05). The positive rate of PLA2R accounted for 84.3%. Lower eGFR and more severe tubulointerstitial lesions were found in PLA2R-positive patients than those in PLA2R-neg-ative patients(P < 0.05). Multiple regression analysis showed that tubulointerstitial lesions(B =-7.253),hyper-tension ratio(B=-10.726)and the level of cholesterol(B=-2.077)had negative correlations with eGFR(P<0.01, R2=0.470). Conclusions IMN patients of male gender,grave proteinuria,high pathological stage and positive PLA2R should be treated more actively , since severe tubulointerstitial lesions and kidney injury were more common in those patients.
