视黄酸对培养的HepG2细胞分泌载脂蛋白AⅠ、AⅡ、B100、CⅢ及E的影响

OBJECTIVE: This study inquired into the role of retinoic acid in lipoprotein metabolism. METHODS: We observed the effect of retinoic acid on the secretion of apolipoproteins A I, A II, C III, B100 and E by cultured HepG2 cells. The apolipoprotiens contents in culture media were measured by radioimmunodiffusion assay (RID) kits developed by our research laboratory. 20-fold lyophilizely condensed culture media were used for the assays. RESULTS: Retinoic acid increased the secretion of apoA I, B100, C III and A II, and it inhibited the secretion of apoE. The effect of retinoic acid was strengthened in a dose-dependent manner. When the concentration of retinoic acid in cultured media was 2 x 10(-4) mol/l, the secretion of apoA I, A II, B100 and C III increased by 14.3% (P < 0.01), 23.8% (P < 0.05), 16.1% (P < 0.01) and 47.6% (P < 0.01) respectively, and the secretion of apoE decreased by 37.2% (P < 0.01). CONCLUSION: These findings indicate that retinoic acid does not have a general effect on apolipoprotein secretion in HepG2 cells.     

中老年男性血糖与血清脂质及载脂蛋白的关系

OBJECTIVE: To gain an insight into the relation of plasma glucose levels to lipids and apolipoproteins levels. METHODS: Fasting 12-14 h blood glucose (BG), high density lipoprotein cholestrol(LDL-C), apolipoproteins(apo) A I, A II, B100, C II, C III and E levels were measured in 735 men aged 40-70 in Chengdu area. The subjects studied were divided into three groups by the plasma glucose levels: 1. normal group (S1), 2. decreased glucose tolerance group (S2), 3. diabetes mellitus (DM) group (S3). RESULTS: Among 735 cases studied, groups S2 and S3 had more hyperlipidemia than group S1 (64%, 45% and 32.2% respectively). The fasting serum mean TG levels in groups S2 (3.62 +/- 2.52 mmol/L) and S3 (4.45 +/- 3.82 mmol/L) group were significantly higher than that in group S1 (1.92 +/- 1.39 mmol/L) (P < 0.01 and P < 0.01), and the mean TG levels in groups S2 (5.68 +/- 1.15 mmol/L) and S3 (5.68 +/- 1.12 mmol/L) were higher than that in group S1 (5.13 +/- 1.06 mmol/L) (P < 0.05, P < 0.05). The serum apo B100, C II, C III and E levels in groups S2 and S3 were significantly higher as compared with that in the normal group (P < 0.01, P < 0.05). The correlation analysis indicated that there was a positive correlation of BG with serum TG in groups S1, S2 and S3 whose correlation coefficients (r) were 0.1800, 0.1436 and 0.3212 respectively (P < 0.001); and a negative correlation with HDL-C levels in groups S2 and S3 (r = -0.2534 and -0.1477, P < 0.001). The plasma glucose levels were positively correlated with apo B100, C III and E levels in groups S1, S2 and S3, P < 0.001), with apo C II in groups S1 and S2 (P < 0.001, P < 0.01); and negatively correlate to apoA I only in group S2 (r = -0.1182, P < 0.01). CONCLUSION: The results suggest that serum TG, TC, HDL-C, apoB100, C II, C III and E levels be the main factors that related to plasma glucose levels.

成都地区正常男性中老年人血清apoB100含量与脂质及apoAⅠ,A…

This study was conducted in 438 normal men aged 40-70. The age groups were: 40-44, 45-49, 50-54, 55-59, 60-64, and 65-70. The results showed that the serum apolipoproteins levels (mean+/- s, mg/L) were: B100 levels 742.5 +/- 165.8, A I 1301.2 +/- 219.9, A II 299.4 +/- 49.0, C II 42.7 +/- 21.4, C III 113.3 +/- 34.0 and E 38.7 +/- 8.2. The levels of serum apoB100 increased with age. The serum apoB100 levels in the 5th and 6th age groups were significantly higher as compared with the groups 1, 2, 3 and 4 (P < 0.05 and P < 0.05). The fasting serum mean TG (1.39 +/- 0.45 mmol/L), TC(4.79 +/- 0.82 mmol/L) and LDC-C(1.62 +/- 0.40 mmol/L levels in the groups 5 and 6 were significantly higher as compared with the groups 1, 2, 3 and 4 (P < 0.01). Serum apoC II, C III and E levels were significantly increased in the groups 5, 6 (P < 0.05). The correlation analysis indicated that there was a positive correlation of apoB100 with serum TG, TC, LDL-C, apoC II, C III and E respectively (P < 0.01); and a negative correlation with HDL-C levels (r = 0.1312); and apoB100 correlated negatively with apoA I (r = -0.0706). The results suggest that serum TG, TC, LDL-C, apoC II, C III and E are the main factors related with the serum apoB100 levels.     

诺衡对糖尿病高脂血症患者aPO,CII,CIII的影响

The effects of gemfibrozil on apolipoproteins C II and C III (apo C II, C III) were observed in 20 NIDDM hyperlipidemic patients. All of the patients continued their anti-diabetic treatment, gemfibrozil 900 mg/day for 4 weeks. The results revealed no significant change in fasting plasma glucose (FPG) and HbA1 before and after the study. But after the treatment with gemfibrozil, the following parameters changed significantly: total cholesterol (TC) decreased by 18.64% (P less than 0.01), total triglyceride (TG) decreased by 65.05% (P less than 0.001), VLDL-C decreased by 63.19% (P less than 0.001), HDL-C increased by 44.23% (P less than 0.001), apo C III decreased by 31.38% (P less than 0.02), and the ratio of apo C III/C II reduced by 35.49% (P less than 0.01). These findings suggest that gemfibrozil has excellent effect on decreasing apo C III and the ratio of apo C III/C II, thus facilitates the metabolism of chylomicron and decreases TG level in hyperlipidemic diabetic patients.     

Correlation of syndrome types in traditional Chinese medicine and insulin release curves in pre-aged and aged diabetics--an analysis of 142 cases

This paper deals with the correlation between insulin release curves and syndrome types of TCM in 142 cases of diabetes. The syndromes were divided into 3 types: I, Qi-Yin deficiency, 94 cases; II, Yin deficiency with interior heat overabundance, 36 cases; and III, deficiency of both Yin and Yang, 12 cases. The results showed that fasting for 60 min, the postprandial (M +/- SD) of serum insulin were 18.27 +/- 1.10 mu/L and 45.21 +/- 2.82 mu/L in type I 25.47 +/- 1.88 mu/L and 60.53 +/- 0.25 mu/L in Type II; 8.29 +/- 0.93 mu/L and 19.20 +/- 1.67 mu/L in type III respectively. It was obvious that serum insulin level was Type II greater than Type I greater than Type III. But there was no difference between the aged and the pre-aged with diabetes (P greater than 0.05); even though the former was lower than the latter. According to the analysis of insulin release curve types (insulin secretion level and peak time), there were 39 cases (41.5%) of the low secretion type, 7 cases (7.5%) of the high secretion type among the 94 cases of Type I. Of the 36 cases of Type II, there were 7 cases (19.4%) of high secretion, more than that of Type I, and the highest value reached 155-106 mu/L. The 12 cases of Type III are all of the lower secretion type, with the fasting mean value being 47.5 mu/L and 10.93 mu/L and the postprandial highest value 21.69 mu/L and 20.73 mu/L, much lower than those of Types I and II. The results also showed that correlation between insulin secretion level and blood glucose value was significantly negative. The paper also discussed the mechanism of insulin secretion condition of 3 syndrome types according to the theory of TCM.

The abnormal changes of apolipoprotein(s) in patients with type 2 diabetes mellitus]

OBJECTIVE: To investigate the changes of the apolipoproteins(apoA I, A II, B100, C II, C III, E) in patients with type 2 diabetes mellitus. METHODS: The levels of fasting plasma glucose(FBG), insulin, TG, TC, apoA I, A II, B100, C II, C III, E were all measured in 127 non-diabetic subjects and 143 type 2 diabetic patients (20 associated with coronary heart disease (CHD) and 66 associated with hypertriglyceridemia(HTG), 55 associated with hypercholesterolemia). RESULTS: In male type 2 diabetic patients, the levels of FBG, WHR and apoC II were significantly higher (P < 0.05) and apoA I, A II levels were significantly lower (P < 0.05) than those in male non-diabetic subjects. In female type 2 diabetic patients, the levels of FBG, BMI, WHR, TG significantly elevated while HDL-C, apoA I, A II levels significantly decreased as compared with those in female non-diabetic subjects. In type 2 diabetic group, the levels of WHR, FBG and TG in HTG patients were elevated significantly as compared with those without HTG, and the levels of HDL-C, apoA I and apoA II were decreased; the levels of WHR, TG, TC, apoB100, C II, C III, E in patients with HTC were significantly higher than those whose cholesterol levels were normal. In patients with CHD, the levels of fasting insulin, apoB100, apoC II and apoE were significantly higher than those in patients without CHD, and the levels of HDL-C and apoA II were decreased significantly. CONCLUSION: Abnormal changes of apo(s) in type 2 diabetes mellitus may be a cause of type 2 diabetes associated with HTG and CHD.
