Expression of Gal-3 and BCL-2 in patients with ulcerative colitis and their significance / 临床与实验病理学杂志

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.
