Objective To evaluate the therapeutic effect and safety of forward-viewing,doublechannel endoscope in the process of ERCP in patients with bile duct diseases after Billroth-Ⅱ gastroenterostomy.Methods ERCP was applied to 46 patients with bile duct diseases using forward-viewing,doublechannel endoscope.All patients had the history of Billroth-Ⅱ gastroenterostomy.The success rate of selective cannulation,complication rate and the outcome of all the patients were recorded.Results The procedure succeeded in 38 patients with a success rate of 82.6%,and failed in 8.Of all the failing cases,the afferent loop couldn't be accessed in 6,failure in biliary cannulation in 2.Of 38 successful cases,bile duct stones were successfully removed in 31,metal stents placed for malignant bile duct obstruction in 4,and endoscopic balloon dilation for benign common bile duct stricture in 3.All patients recovered without complications of perforation,delayed bleeding or pancreatitis.Conclusion For patients with history of Billroth-Ⅱgastroenterostomy,ERCP with forward-viewing,double-channel endoscope yields to a higher success rate and lower complication rate.

Objective To investigate the characteristics of etiology,efficacy of endoscopic management for recurrent idiopathic pancreatitis (RIP).MethodsThe clinical data of 58 cases of RIP diagnosed in our hospital from April 2005 to April 2011 were retrospectively analyzed.All the patients underwent endoscopic retrograde cholangiopancreatography (ERCP),and patients with suspected sphincter of Oddi dysfunction received manometry.According to the clinical and ERCP manifestations,the etiologies of RIP were determined and individualized endoscopic treatment was applied.The patients were followed-up postoperatively about the improvement of abdominal pain and recurrence of RIP.ResuItsFifty-eight patients (29 males,29 females) were suffered from acute pancreatitis from 3 to more than 10 times.The etiologies were as follows:29 cases of biliary microlithiasis,19 case of sphincter of Oddi dysfunction ( 16 cases of pancreatic type,3 cases of mixed type),4 cases of anomalous arrangement of the pancreaticobiliary duct,and 6 cases of normal manifestations at ERCP.Biliary sphincterotomy alone was performed in 33 patients,while both biliary and pancreatic sphincterotomy was performed in 8 patients,and pancreatic sphincterotomy alone was performed in 17 patients,after sphincterotomy,pancreatic stent insertion was performed in 24 patients.The follow-up data was obtained from 41 out of 58 patients,the follow-up period ranged from 3 ~ 67 months ( average 33 months).During this period,9(22.0% ) patients suffered from RIP,and the treatment efficiency was 78%.ConclusionsBiliary microlithiasis and sphincter of Oddi dysfunction are the main causes of RIP.Drink could induce RIP.ERCP has definite treatment efficacy for RIP.

The effect of dark tea fermentation liquid with Eurotium Cristatum on the activity of digestive enzyme was researched, as fellowing amylase, protease, lipase. The results showed that dark tea fermentation liquid with Eurotium Cristatum may increase remarkably the activity of ?-amylase and protease, but decrease efficiently the activity of lipase. The fermentation liquid improves the digestion and absorption of starch and protein, but inhibits the decomposition and absorption of fat, so it can explain the mechanism of Fu-brick tea's health functions.

Background The pathogenesis of age-related cataract is associated with the apoptosis of lens epithelial cells (LECs) caused by oxidative stress.Previous studies showed that intracellular focal adhesion kinase (FAK) pathway can be activated by H2O2 in vitro,which induced apoptosis of cells.To investigate the effect of oxidative on FAK expression in LECs is one of important studies in the prevention of age-related cataract.Objective This study was to investigate the expression and function of FAK in human LECs treated by H2O2.Methods Human LECs strain (HLECs-B3) were cultured in vitro in the low glucose DMEM with 10% fetal bovine serum.Different concentrations (0,30,50,70,100,300,500,700,1000 μmol/L) of H2O2 were added into the culture medium for 24 hours.The survival rate of the cells was detected by Cell Counting Kit-8 (CCK-8) assay.Cell morphology as well as the expression and distribution of FAK in the cells were observed by immunofluorescent staining under the laser confocal microscope.Apoptosis was observed by hoechst33258 staining,and Western blot assay was used to quantitatively detect the expression and phosphorylation of FAK.Results The survival rate of the cells was (1.00±0.03) %,(1.24±0.03)%,(1.36±0.24) %,(0.93±0.02)%,(1.75±0.19)%,(1.37±0.18) %,(0.64±0.01)%,(0.59±0.11)%,(0.14±0.05)% in 0,30,50,70,100,300,500,700,1000 μmol/L H2O2 groups,with a significant difference among them (F =95.30,P =0.00).The survival rates of the cells in the below 300 μmol/L H2O2 groups were significantly higher than those in the 0 μmol/L H2O2 group,and survival rates of the cells in the above 500 μmol/L H2O2 groups were significantly lower than those in the 0 μmol/L H2O2 group(all at P<0.05).After H2 O2 treatment for 24 hours,HLECs-B3 cells transformed from polygon shape to spindle shape and extended pseudopodiums,meanwhile the green fluorescence for FAK exhibited in the cytoplasm.Cell apoptosis was found in the 1000 μ mol/L H2O2 group.Western blot assay revealed that the expressing levels (grey scale) were significantly different among the various groups (F=28.08,P=0.00),and FAK expressing levels in the below 300 μmol/L H2O2 groups were significantly higher than those of the 0 μmol/L H2O2 group; while the expressing levels in the above 500 μmol/L H2O2 groups were lower than those of the control 0 μmol/L H202 group (all at P<0.05).After treated by different concentrations of H2O2,the phosphorylation level of intracellular FAK (p-FAK) was significantly higher in 3 hours group than that in 30 minutes group (all at P<0.05).Conclusions H2 O2 can affect the survival,proliferation and morphology of human LECs by activating the intracellular FAK pathway,indicating that FAK may play roles in the regulation process of cell biological behavior.

To explore a new strategy for further optimization to the C-3 bioisteric heterocyclic ring of fluoroquinolones,twelve novel fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives(7a-71) were designed and synthesized with both functionalized sulfanylacetic acid and Schiff-base moieties as the modified side-chain for the C-3 bioisosteric s-triazole ring of pefloxacin(1).The structures were characterized by elemental analysis and spectral data,and the in vitro anti-tumor activity of the title compounds against SMMC-7721,L1210 and HL60 cell lines was evaluated.The preliminary pharmacological results demonstrated that the title compounds possessed more significantly anti-proliferative activity than either the parent 1 or the corresponding amine intermediates(6).In particular,the title compound bearing a fluorine atom (7j) and compound bearing a nitro group attached to benzene ring (71) were comparable to the control doxorubicin against SMMC-7721 cells with an IC50 value of micro-molar concentration,respectively.It suggests that s-triazole ring modified with functional side-chain moieties instead of the C-3 carboxylic group is favorable to the improvement of antitumor activity.

Objective To explore the effect of fibroblast growth factor receptor(FGFR)inhibitor BGJ398 on the vasculogenic mimicry(VM)formation of glioma cells. Methods The phosphor-FGFR(pFGFR)was de-tected by Western blot,the expressions of MMP2 and MMP14 were detected by Western blot and immunocytochem-istry;the VM formation of U87MG and U251MG was tested by tube formation assay;subcutaneously implanted tu-mor model in nude mouse was established and tumor sections were CD34/PAS double-stained to detect the forma-tion of VM in vivo. Results Western blot showed that pFGFR in the experimental groups decreased significantly (P < 0.05);western blot and immunohistochemical staining showed that the expression of MMP2 and MMP14 in the experimental groups decreased significantly compared to the control group. In the tube formation assay ,the tube formation of U87MG and U251MG cells were restrained. In the subcutaneously implanted tumor model ,the VM number of the experimental group(13.85 ± 3.96)was significantly lower than that in the control group(26.40 ± 5.06,P < 0.05). Conclusions In vivo and in vitro experiments confirmed that BGJ398 can inhibit the activa-tion of FGFR,and inhibit the VM formation of glioma cells. These indicate FGFR signaling pathway is involved in the formation of VM.
