Objective To explore the influence factors of cirrhosis complicated with upper gastrointestinal bleeding,and to guide the clinical treatment of patients with cirrhosis and prevent upper gastrointestinal bleeding.Methods One hundred and seventy-five cases patients with cirrhosis and upper gastrointestinal bleeding were treated in the Infectious Disease Hospital of Tangshan and the Affiliated Hospital of North China University of Science and Technology from July 2013 to July 2015 as the case group.One hundred and eighty-two patients with cirrhosis and no upper gastrointestinal bleeding at the same period in hospital as the control group.A face to face questionnaire was used to fill in the questionnaire.Results Multifactor conditional Logistic regression analysis showed that onset season (OR =4.185,95％ CI:1.874-8.354),non steroidal drugs (OR =6.215,95％ CI:2.681-15.532),drinking (OR =5.481,95％ CI:3.205-11.225),portal vein highpressure gastropathy(OR =7.658,95％ CI:3.227-14.714),diameter of portal vein (OR =8.901,95％ CI:1.218-9.026),liver function classification (OR =13.124,95 ％ CI:2.107-15.228) and esophageal varices (OR =11.021,95％ CI:2.181-13.487) were related with patients with liver cirrhosis complicated with upper digestive tract hemorrhage.Conclusion The onset season,nonsteroidal anti-inflammatory drugs,drinking,portal hypertensive gastropathy,portal vein diameter,liver function classification and esophageal varices are the risk fators of liver cirrhosis complicated with upper digestive tract hemorrhage factors.

Objective:To evaluate the effect of epigallocatechin-3-gallate (EGCG) and epigallocatechin-3-O-(3-O-methyl)-gallate (EGCG-3Me) on the anti-bacterial effect and the stability of intraradicular dentin-adhesive interface.Methods:EGCG and EGCG3Me with the concentration of 400 μg/ml were incorporated into Single Bond 2 (SB2) respectively to obtain 2 modified adhesives E-SB2 and E3-SB2.Confocal laser scanning microscopy(CLSM) and ultraviolet spectrophotometry were used to evaluate the anti-bacterial effect of the modified adhesives.Micro-Raman spectrum was used to test the degree of conversion (DC) of the adhesives.Push-out bond strength test was conducted to examine the immediate bond strength and the bond strength after themocycling.Results:E-SB2 and E3-SB2 both showed inhibiting effect on the proliferation of E.faecalis,while E3-SB2 performed stronger inhibiting effect.DC and the immediate push-out bond strength of SB2 were not decreased with the incorporation of EGCG or EGCG-3Me(P ＞ 0.05).E-SB2 and E3-SB2 showed significantly higher push-out bond strengths than that of SB2 (P ＜ 0.05) after themocycling.Conclusion:EGCG and EGCG-3Me modified adhesives have anti-bacterial effect and can enhance the stability of bonding between intraradicular dentin and adhesive,EGCG-3Me may have stronger anti-bacterial effect.

Objective To explore the risk factom of hepatitis B virus infection and alcoholic liver disease in patients with decompensated cirrhosis complicated with liver failure.Methods One hundred and fifty-eight cases hepatitis B virus infection and alcoholic liver disease in patients with decompensated cirrhosis were selected.According to whether complicated with liver failure,the patients were divided into observation group with 62 cases (complicated with liver failure group) and control group with 96 cases (without liver failure group).The clinical data and results of 2 groups were analyzed to screen the risk factors of liver failure.Results Compared with control group,observation group in alanine aminotransferase,aspartate aminotransferase,cholinesterase,total bilirubin,and prothrombin time,activated partial thrombin time live enzymes,thrombin time,fibrinogen,serum creatinine,the differences were not statistically significant (P ＞ 0.05);in albumin ((28.02±7.36) g/L vs.(23.26±6.54) g/L,t =4.421,P =0.002),serum urea nitrogen ((8.84±4.71) mmol/L vs.(9.33±5.24) mmol/L,t =3.656,P=0.007),upper gastrointestinal bleeding(x2 =7.534,P=0.006),ascites (x2 =8.615,P =0.003),infection (x2 =10.321,P =0.001),hepatic encephalopathy (x2 =6.561,P =0.010),hepatorenal syndrome(x2 =4.952,P=0.026),the difference were statistically significant.(2)The results of logistic regression analysis showed that upper gastrointestinal bleeding (OR =1.020,95％ CI:1.003-1.036),hepatorenal syndrome(OR=2.872,95％CI:0.385-21.423) were risk factor of hepatitis B virus infection and alcoholic liver disease in patients with decompensated cirrhosis complicated with liver failure.Conclusion Upper gastrointestinal bleeding,hepatorenal syndrome are independent risk factors of hepatitis B virus infection and alcoholic liver disease in patients with decompensated cirrhosis complicated with liver failure.
