Objective To study the clincial effectiveness and safety of endoscopic sphincteropapillotomy combined with balloon dilation for decompensated cirrhosis accompanied with choledocholithiasis.Methods Data of 79 cases of decompensated cirrhosis patients with choledocholithiasis who underwent limited endoscopic sphincterotomy plus endoscopic papillary balloon dilation (ESBD,the ESBD group) and 42 cases who underwent endoscopic papillary balloon dilation(EPBD,the EPBD group)were retrospectively analysed and compared for complete stone clearance rate,one-time stone clearance rate and complications.Results The rate of complete stone clearance and one-time stone clearance were 94.9％ (75/79) and 77.2％ (61/79)in ESBD group,and those were 88.1％ (37/42) and 59.5％ (25/42) in EPBD group respectively.The rate of complete stone clearance was a little higher in ESBD group than that in EPBD group.In ESBD group,ERCP-related bleeding occurred in 3 patients (3.8％),post-ERCP hyperamylasemia in 3 (3.8％)and post-ERCP pancreatitis in 2 (2.5％) ; while in EPBD group,post-ERCP hyperamylasemia occurred in 8 patients(19.0％),post-ERCP pancreatitis in 6(14.3％) and ERCP-related bleeding did not occur.There were no significant difference in ERCP-related bleeding between ESBD group and EPBD group (P =0.551).However,the rates of post-ERCP pancreatitis and hyperamylasemia in ESBD group were significantly lower than those in EPBD group(P ＜ 0.05).Conclusion ESBD is a safe and effective procedure for choledocholithiasis accompanied by decompensated cirrhosis,with several advantages over EPBD in terms of higher one-time stone clearance rate,reduced risk of post-ERCP pancreatitis and hyperamylasemia,and without noticeable increase in the risk of bleeding related to ERCP.

Objective To investigate the impact of hyper-homocystinemia (Hcy)on cardiac remolding in spontaneously hypertensive rat(SHR)and the protective effects of folic and vitamin B12 on the remolding.Methods The seven-week-old SHR were divided into four groups according to different diet for 20 weeks.The control group was fed a perfect compound diet without methionine,the methionine group was fed a perfect compound diet added with 2 ％ methionine,the treatment group was fed as that of methionine group,but added with vitamin B12 0.09 mg/(kg.d)and folate 4 mg/(kg.d)in the last 12 weeks,the mixture group was fed as that of methionine group in the first 8 weeks,and as that of control group.At the end of the intervention period,plasma levels of Hcy and matrix metalloprotease(MMP)-9 were measured.The blood pressure was detected by the non-invasive blood pressure sensing device.The cardiac structure and function were detected using echocardiography and invasive hemodynamic method.Picro-sirius red(PSR)staining was used to check the fibrosis in paraffin embedding ventricle section.Results Plasma levels of Hcy and MMP-9 were increased in the methionine group,while there was no significant difference in plasma levels of Hcy and MMP-9 among the treatment group,the mixture diet group and control group.Rats in methionine group had the largest heart weight among four groups,and systolic blood pressure was lower in methionine group than in the control group(P＜0.05).Compared with the other three groups,the methionine group showed that the left ventricular end-diastolic pressure(LVEDP)was increased and-dp/dt maxwas decreased.Meanwhile,LVEDP and-dp/dt m,x had no significant difference between the control group,treatment group and mixture group.The methionine group showed the most severe decrease in the left ventricular fractional shortening(LVFS)and +dp/dt While LVFS and + dp/dt max had no statistical significance between the treatment group and control groups,but the mixture group had lower LVFS and +dp/dt max values as compared with the control group(both P＜0.05).Perivascular fibrosis was increased significantly in methionine group as compared with the other three groups,while the treatment and control groups had similar perivascular fibrosis,but the mixture group had higher perivascular fibrosis than did the control group,and had similar perivascular fibrosis to the treatment group.Fibrosis deposition in myocardium mesenchymal was similar to those observed in perivascular fibrosis,but the treatment group showed a more improvement of collagen deposition as compared with the mixture group.Conclusions Hyper-homocystinemia can accelerate systolic and diastolic dysfunction through accumulating fibrosis in myocardium and perivascular wall which lead to adverse cardiac remolding.Folate and vitamin B12 have protective effects on heart function by reversing the adverse changes through decreasing Hcy level.

Objective To explore the relationships between resistin rs1477341 , rs3219175 and type2 diabetes mellitus (T2DM) in Guangdong. Methods 180 patients of diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2013 to December 2014 were enrolled in the study as the treatment group and another 180 subjects taking health examination as the control group. The genotype distributions of rs1477341 locus A/T, rs3219175 locus A/G were compared and the relationship between the genotypes and T2DM were anlysed by the logistic regression. Results The frequencies of the rs1477341, rs3219175 locus genotype reached the genetic equilibrium, showed their representativeness of a population group. The frequency distribution of rs1477341 genotype was statistically insignificant across the two groups (P > 0.05). The frequency of rs3219175 genotype AA+AG was decreased while genotype GG increased significantly compared to the control group (P < 0.05). The logistic regression results suggest genotype GG may increase disease risk of T2DM which the morbidity rate of AG homozygote was 0.630 times as high as that of GG homozygote (OR =0.630, 95%CI:0.405 ~ 0.980, P < 0.05) and the morbidity rate of GG homozygote was 1.551 times as higher as that of AA+AG homozygote (OR = 1.551, 95%CI:1.016 ~ 2.368, P < 0.05). Conclusions rs1477341 genotype has no correlation with T2DM among the population in Guangdong , but rs3219175 genotype does. GG may have a higher susceptibility to T2DM.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective　To evaluate the expression of Fas/FasL antigen on peripheral blood T lymphocytes and its possible role in Behcet disease. Methods　The expression of Fas and FasL antigen on peripheral blood T lymphocytes was determined by flow cytometry and three-colour double marked immunofluorescence methods in 26 patients with Behcet disease and 43 healthy individuals. Results　The difference was significant between Behcet disease (25.70%±7.32%) and controls (14.02%±6.30%) concerning the Fas expression on CD4+ T lymphocytes(P＜0.01) . But no difference was found concerning the expression of FasL antigen between Behcet disease and controls (P＞0.05).The expression of Fas antigen on CD8+ T lymphocytes from Behcet disease (9.47%±6.97%)was significantly higher than that in control group(3.47%±2.75%), but no difference was found concerning FasL antigen expression on CD8+ T lymphocytes between Behcet disease and controls(P＞0.05).Conclusion　These results indicate the imbalance of the expression of Fas and FasL on T lymphocytes in Behcet disease is responsible for the perpetuation and recurrence of Behcet disease for the activated lymphocytes would not be eliminated through apoptosis mediated by Fas/FasL system.

Objective To investigate the effects of macrophage inflammatory protein-1α (MIP-1α) combined with molecule 4-1BB L on the tumorigenicity of hepatocellular carcinoma cells in vivo. Methods Mouse MIP-1α (mMIP-1α) expressed Hepa 1-6 cells were transfected with m4-1BBL recombinant retrovirus, the anti-histidinol cells clones were selected and amplified. The expression of m4-1BB L was confirmed by flow cytometry. The growth curve of Hepa 1-6 cells transfected with mMIP-1α and m4-1BBL alone or together was drawn and compared. C57B/L Mice were randomly divided into 7 groups, 9 mice in each group, injected with mMIP-1α+m4-1BB L Hepa 1-6 cells, m4-1BB L Hepa 1-6 cells, mMIP-1α Hepa 1-6 cells, Hepa 1-6 cells, pLXSHD Hepa 1-6 cells or PBS respectively. The tumorigenicity of hepatocellular carcinoma cells and the mice survival rate were compared between each groups. Results Hepa 1-6 mMIP-1α+m4-1BB L cells which expressed both mMIP-1α and m4-1BB L were successfully established. The expression of mMIP-1α and m4-1BB L alone or together did not affect the growth curve of Hepa 1-6 cells. Observed for 5 weeks, no tumor developed in Hepa 1-6 mMIP-1α+m4-1BB L injected mice. The tumorigenicity of Hepa 1-6 mMIP-1α+m4-1BB L was lower than that of Hepa 1-6 mMIP-1α or Hepa 1-6 m4-1BB L in vivo. The survival rate of Hepa 1-6 mMIP-1α+m4-1BBL injected mice(9/9) was higher than that of Hepa 1-6 m4-1BB L injected mice (6/9)or Hepa 1-6 mMIP-1α injected mice (1/9). Conclusion Chemokine MIP-1α combined with costimulatory 4-1BB L lowered the tumorigenicity of hepatocellular carcinoma cells in vivo, and prolonged the mice survival period.
