ABSTRACT

Purpose To study the expression and significance of Gal-3 and BCL-2 in ulcerative colitis (UC).Methods 64 cases of patients diagnosed as UC in the Department of Digestive Dseases were selected as the observation group in our hospital from August 2014 to December 2015.And 50 healthy volunteers were selected as control group.The expression levels of BCL-2 and Gal-3 in the two groups were detected,and the correlation between and UC and between BCL-2 and Gal-3 was studied.Results The positive rate of Gal-3 in the control group was 100%,higher than 37.5% in the observation group(x2 =48.142,P <0.001).The positive rate of BCL-2 in the control group was 20%,which was lower than that in the observation group of 90.62% (x2 =58.171,P < 0.001).The Gal-3 positive rate of UC Grade Ⅰ was higher than UC Grade Ⅱ (x2 =5.539,P =0.019),The Gal-3 positive rate of UC Grade Ⅰ was higher than UC Grade Ⅲ (x2 =4.532,P =0.033),The Gal-3 positive rate of UC Grade Ⅲ was lower than UC Grade Ⅱ (x2 =0.183,P=0.669).The BCLo2 positive rate of UC Grade Ⅰ was lower than UC Grade Ⅱ (x2 =5.539,P=0.019).The BCL-2 positive rate of UC Grade Ⅰ was lower than UC Grade Ⅲ (x2 =6.098,P=0.014).The BCL-2 positive rate of UC Grade Ⅲ was higher than UC Grade Ⅱ (x2 =0.511,P =0.475).BCL-2 and Gal-3 expression was not related to gender,age and disease duration (P > 0.05).The expression of BCL-2 and Gal-3 was not correlated.Conclusion The expression level of BCL-2 in UC is higher than that in normal colorectal mucosa.The expression level of Gal-3 is lower than that of normal colorectal mucosa.The expression of UC has no effect on sex,age and course of disease,and it could be used as the prediction standard of UC.

ABSTRACT

Objective To investigate the potential influencing factors which possibly effected the gut barrier function.The effort was made to establish a clinical evaluation system of gut barrier dysfunc- tion.Methods Fifty-three critically ill patients with an APACHEⅡscore of 8 or more and 27 patient which APACHEⅡscore was 6 or less were recruited.Plasma was reserved for measurement of endo- toxin,tumor necrosis factor-?,diamine oxidase,D-lactic acid and high sensitive C reactive protein,uri- nary excretion of lactulose and mannitol and the urinary content of intestinal fatty acid binding protein (IFABP) were determined as well.Analyses was achieved by univariate,multivariate analysis and receiver operating characteristic curve.Results In the logistic regression models,gut barrier was affect- ed by many factors.The ratio of lactulose and mannitol in urine,the urinary content of IFABP of 24 hours and endotoxin level of plasma were identified as the most intimate factors which could associate with gut barrier function.The optimal operating point of plasma endotoxin,ratio of urinary lactulose and mannitol and content of urinary IFABP of 24 hours were 0.145,17 ng and 0,055 EU/ml respectively based on the results of receiver operating characteristic curve,the sensitivity and specificity were 84.5% vs 88%,78% vs 88% and 78% vs 78%.The doubtable value interval of urinary ratio of lactulose and mannitol was limited as 0.178 to 0.082.Conclusion Gut barrier dysfunction should be suspected when critically ill patients presented eertains gastrointestinal symptoms and had the proofs of increasing intesti- nal permeability,hypoperfusion of gut and higher level of plasma endotoxin.
