Object To study the effect of geniposide in the prophylaxis of cholesterol calculus formation in gall ducts of Syria Golden hamster Methods Experimental hamster models with cholesterol calculus was prepared by feeding lithogenous diet with high content of fat and protein for 30 d with simultaneous administration of geniposide at doses of 50 and 100 mg/kg/d ig or ursodeoxycholic acid as positive control at the dose of 80 mg/kg/d After the last dosage, the hamsters were sacrificed and their gallstone formation rate were determined by examining the smear of gallbladder content and their lithogenous index (LI) were calculated from the assay of lipoid substances in bile such as cholesterol (Ch), bile acids (Bs) and phospholipid (Pl) Results The gallstone formation rate in the blank model group, geniposide 50 and 100 mg/kg were 100%, 40% (P

Objective To investigate the nutritional status of patients with heart failure and its effect on all-cause mortality.Methods A total of 351 patients with chronic heart failure,who were consecutively admitted to the East Hospital of Shanghai from March 2013 to November 2015,were put into the heart failure with reduced left ventricular ejection fraction (HFrEF) group.They were compared to 222 controls who were admitted during the same period for preclinical heart failure.After a median follow-up time of 606 days,108 patients of the HFrEF group died,compared to 11 of the controls.Logistic regression was used to analyze correlations of all-cause mortality with the patients' body mass index (BMI),serum albumin and other factors.Results Compared to the controls,patients with chronic heart failure had lower BMI [(22.71±3.95) kg/m2 vs.(24.23±3.66) kg/m2,t=4.331,P=0.000],total cholesterol [(3.81±0.99) mmol/L vs.(4.03±0.96) mmol/L,t=2.638,P=0.009],albumin [(38.18±5.03) g/Lvs.(40.18±6.12) g/L,t=3.874,P=0.000] and prealbumin [(187.67±61.83) mg/L vs.(211.94±65.44) mg/L,t=3.937,P=0.000].Within the HFrEF group,patients with lower BMI had higher mortality (36.0％ vs.22.4％,P=0.008).Logistic regression suggested BMI,age were independent predictors of all-cause death.Conclusions Patients with chronic heart failure had high incidence of malnutrition,and those with BMI＜22 kg/m2 had higher risk of mortality.Serum albumin and BMI not only reflected nutritional status of the patients but had significant implications on prognosis.
