Objective To investigate Lovastatin's effects on proliferation and adhesion of human umbilical vein endothelial cells (HUVECs). Methods Culture medium with different concentration of Lovastatin(0.001、0.01、0.1、1.0、10μmol/L) was prepared, HUVECs was cultured in 96 well-plate with the different medium. AT the point of 24,72 and 120 h, the cell's activity and quantity was assessed by MTT. HUVECs was cultured with Lovastatin in 6 well-plate for 24 hours, then collected the cells by trypsin digestion. The cells were seeded in 24 well-plate with 2×104/ml and adhering for 30 mins. Then counting the adhered cells in different wells. Results At 24 h, Lovastatin (0.01、 0.1 μmol/L ) promoted proliferation of HUVECs ( P ＜ 0.05 ); at 72 h, Lovastatin ( 1.0μmol/L) was positive accelerating cell growth(P＜ 0.05 ). While Lovastatin ( 10μmol/L) inhibited the proliferation significantly ( P ＜0.05 ) at 120 h. As HUVECs was cultured with Lovastatin for 24 hours, Lovastatin (0.1、1μmol/L) inhanced the adhesion capability of HUVECs significantly( P＜ 0.05 ). Conclusion Lovastatin had biphasic effects on proliferation and adhesion of HUVECs dependent on the concentration. Lovastatin (0.1、1.0 μmol/L) could promote the proliferation and adhesion, while at higher concentration ( 10.0μmol/L) it inhibits cell proliferation and adhesion.

Objective To investigate familial hyperlipoproteinemia and the features of familial hyperlipoproteinemia in Lanzhou . Methods Data were from previous studies on the subject .Families of hyperlipoproteinemia were screening ,questionnaires were col-lected ,physical examination and laboratory data of family members were also colleted to analysis the characteristics of familial hy-perlipoproteinemia .Results A total of 39 familial hyperlipoproteinemia families were enrolled in the study ,including 280 family members .There were 15 core families ,11 single-parent families ,and 13 orphaned families .There were 6 familial hypercholesterol-emia families ,9 familial hypertriglycerides families ,24 mixed familial hyperlipidemia families .The children of the first generation ac-counted for 63 .2% of the total number of people enrolled in the study ,the father generation accounted for 14 .3% ,the children of the second geration accounted for 22 .5% .Conclusion In the survey ,the most common type of familial hyperlipidemia was mixed familial hyperlipidemia .The father generation was majority .The member of core families was less than incomplete families .

Objective: To study the effect of curcumin on cardiac remodeling and heart function change induced by adriamycin in rats. Methods: A total of 50 SD rats were randomly divided into blank control group (n=10), adriamycin group (n=20) and curcumin intervention group (n=20). General conditions of rats, including weight, hair color, diet and activity capacity, were observed. Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) and left ventricular end-diastolic dimension (LVEDd) were observed by echocardiography. Rat heart was weighed and levels of cardiac collagen type Ⅰ and Ⅲ were observed using immunohistochemistry method. Results: Compared with blank control group after experiment, there were significant increase in heart weight [(168.53±26)mg vs. (208.34±31)mg], heart weight/body weight [(0.36±0.06) vs. (0.52±0.08)], and significant decrease in body weight [(469.27±34)g vs. (428.47±45)g]; significant increase in LVEDd [(4.87±0.19)mm vs. (7.49±0.83)mm], significant decrease in LVEF [(69.53±6.25)% vs. (41.46±4.38)%] and LVFS [(45.83±3.79)% vs. (17.25±2.92)%] in adriamycin group, P<0.05 all, significant increase in expression rates of collagen type Ⅰ and Ⅲ, P<0.01.Compared with adriamycin group, there were significant increase in body weight (452.46±38)g, significant decrease in heart weight (178.73±38)mg, heart weight/body weight (0.39±0.07); significant decrease in LVEDd (5.96±0.65)mm and significant increase in LVEF (53.12±5.43)% and LVFS (36.57±3.66)%, P <0.05 all; significant decrease in expression rates of collagen type Ⅰ and Ⅲ in curcumin group, P <0.01. Conclusion: Curcumin can improve cardiac remodeling and heart function induced by adriamycin in rats.
