Characteristics of serum lipids,leptin,cholecystokinin and bile lipids in patients with cholecystolithiasis / 中华消化杂志

ABSTRACT

Objective To investigate the association of serum lipid,lipoprotein,apolipoprotein,leptin,cholecystokinin(CCK)and bile lipid with cholesterol gallstone formation.Methods The patients with gallstone were divided into cholesterol(n=99)and non-cholesterol(n=57)gallstone groups by infrared spectometry.And 52 healthy volunteers were served as control group.The concentrations of serum cholesterol,triglyceride,high and low density lipoproteins,apolipoprotein(Apo),leptin and CCK were measured and compared among three groups.The levels of total bile cholesterol,bile acid and lecithin were also detected.Results The concentrations of serum triglyeeride and total cholesterol in two gallstone groups were higher than those in control group(P value all＜0.01).The level of Apo-B in cholesterol gallstone group was higher than that in control group(P=0.017).While the concentrations of high density lipoprotein and CCK were significantly lower in two gallstone groups than those in control group(P value all=0.000).Serum leptin was higher in male patients compared to controls(P＜0.05).The bile cholesterol saturation index in two gallstone groups was above 1.Conclusions The changes of serum CCK,triglyceride,total cholesterol,high density lipoprotein,Apo-B and leptin may be correlated to the formation of gallbladder gallstone.
