ABSTRACT
Objective To investigate the relationship between peri-menopausal women blood lipid level and the gallstone disease in order to provide theoretical basis for the prevention of gallbladder stone.Methods Seventy-two patients with gallbladder calculus from Department of Hepatobiliary Surgery Jinshan District Central Hospital of Shanghai and 52 healthy women coming for physical examination as the control group.Participants were divided into five age groups (20-29,30-39,40-49,50-59 and 60-69 years old) and two age stages (young period (30-40 years old) and peri-menopausal period (45-55 years old)),total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL-C),low-density lipoproteins (LDL-C) and Body Mass Index (BMI) were determined and compared between the stone group and the control group at different age stages.Results In comparison of the menopausal transition period,the stone group had significantly lower blood TC,HDL-C and LDL-C levels than the control group (TC:(4.58 ± 0.27) mmol/L vs.(5.15 ± 0.26) mmol/L,t=3.112,P ＜0.01 ;HDL-C:(1.17 ±0.11) mmol/L vs.(1.40 ±0.08) mmol/L,t =3.351,P ＜0.01 ;LDL-C:(2.71 ± 0.30) mmol/L vs.(3.15 ± 0.26) mmol/L,t =2.437,P ＜ 0.05).For the young period,there were no significant difference on blood lipid level and BMI was observed between the stone group and the control group (P ＞ 0.05).The fat HDL-C level in blood was significantly lower in the stone group in the menopausal transition period than in the young period ((1.17 ± 0.11) mmol/L vs.(1.33 ± 0.07) mmol/L,t =2.455,P ＜ 0.05).The control group had significantly higher peri-menopausal TC,TG,LDL-C levels in blood and BMI than those in the control group young period (P ＜ 0.05) ; And HDL-C level,no significant difference (TC:(5.15 ± 0.26)mmol/L vs.(4.47 ± 0.34) mmol/L,t =3.175,P ＜ 0.01 ; TG:(1.88 ± 0.39) mmol/L vs.(1.10 ± 0.24)mmol/L,t=3.066,P＜0.01;LDL-C:(3.15 ±0.26) mmol/L vs.(2.71 ±0.31) mmol/L,t =2.261,P＜0.05;BMI:(24.75±0.99) kg/m2vs.(21.73±1.11) kg/m2,t=4.217,P＜0.01).Conclnsion For perimenopausal (45-55 years old) females,decline of serum TC,HDL-C and LDL-C levels may be related to the formation of cholesterol stone.Lower HDL-C level is closely associated with formation of cholesterol stone,indicating that it may be one of the measures to prevent gallbladder stone by adjusting blood fat in perimenopausal women.
ABSTRACT
For the preservation of health in rural areas, this paper reports on the variation of human serum lipids by intaking lentinus edodes.<BR>Serum lipids levels showed no significant change by intaking lentinus edodes that amounts of 20, 40 and 60g per day each for 5 days. From data of correlationship between serum lipid levels and nutrition intake of experimental diet, it was recognized that high-density-lipoprotein cholesterol level was directly proportional to carbohydrate-fat ratio significantly (p< 0.02), and was inversely proportional to fat intake, fat-protein ratio and carbohydrate-protein ratio significantly (p< 0.05), respectively. Triglycerides level was inversely proportional to protein intake significantly (p< 0.05).<BR>These results concluded that the decrease of serum cholesterol level by intaking of lentinus edodes in healthy young men whose serum cholesterol levels were in normal range was not recognized.
