内源性睾酮对血浆脂质、脂蛋白和载脂蛋白水平的影响

对１０２例冠心病患者及９９名健康人进行了血浆睾酮、雌二醇、空腹血糖（ＢＳ）、总胆固醇（ＴＣ）、甘油三酯（ＴＧ）、高密度脂蛋白－胆固醇（ＨＤＬ－Ｃ）、低密度脂蛋白（ＬＤＬ－Ｃ）、脂蛋白（ａ）［Ｌｐ（ａ）］、载脂蛋白（Ａｐｏ）ＡＩ，ＡｐｏＢ１００测定。观察到血浆睾酮与ＴＧ和Ｌｐ（ａ）呈负相关，而与血浆ＨＤＬ－Ｃ和ＨＤＬ３－Ｃ呈正相关。血浆睾酮水平低下组，其ＴＧ和Ｌｐ（ａ）浓度明显高于血浆睾酮水平正常组；而ＨＤＬ－Ｃ和ＨＤＬ３－Ｃ水平则前者明显低于后者。冠心病组血浆睾酮水平明显低于健康对照组。提示内源性睾酮对体内血脂代谢有良好的调节作用；血浆睾酮水平低下则可引起血脂异常，是冠心病的危险因素

Lipids and apolipoproteins in plasma VLDL, IDL, LDL, HDL2 and HDL3 isolated by one-step density gradient ultracentrifugation from 7 subjects with endogenous hypertriglyceridemia (HTG) and 4 normalipemics were determined. HTG VLDL was enriched with cholesterol, and its triglyceride (TG), phospholipid (PL) and apo CII, CIII contents (mg/100 mg protein) were significantly higher than those in normal VLDL. ApoE content in HTG VLDL was prone to increasing, and apoB100 content had no apparent difference from that in normal VLDL. Compared with normal HDL2 and HDL3, the contents of total cholesterol (TC), apoAI, CII, and CIII in HTG HDL2, and apoCII, CIII in HTG HDL3 decreased. HTG HDL2 and HDL3 were rich in TG. By analysis of distribution of these lipids and apolipoproteins in various plasma lipoproteins, it was found that the abnormal composition of VLDL and HDL in HTG seemed to be a result of transport of TC, PL, and apoCII, CIII from HDL to VLDL. There was a significantly positive correlation between TC and apoAI, CII, CIII in HDL respectively, which indicated that apoCII and CIII were also associated with the alteration of HDL cholesterol. It is suggested that the elevated plasma VLDL-TG concentration in endogenous hypertriglyceridemia may induce abnormal redistribution of lipid and apolipoprotein among apoCII plasma lipoproteins, and and CIII may play an important role in these changes.

Effect of a high-fat ketogenic diet on plasma levels of lipids,lipoproteins, and apolipoproteins in children

Context  Little prospective long-term information is available on the effect of a ketogenic diet on plasma lipoproteins in children with difficult-to-control seizures. Objective  To determine the effect in children with intractable seizures of a high-fat ketogenic diet on plasma levels of the major apolipoprotein B (apoB)–containing lipoproteins, low-density lipoprotein (LDL) and very LDL (VLDL); and the major apolipoprotein A-I (apoA-I)–containing lipoprotein, high-density lipoprotein (HDL). Design, Setting, and Patients  A 6-month prospective cohort study of 141 children (mean [SD] age, 5.2 [3.8] years for 70 boys and 6.1 [4.4] years for 71 girls) with difficult-to-treat seizures who were hospitalized for initiation of a high-fat ketogenic diet and followed up as outpatients. This cohort constituted a subgroup of the 371 patients accepted into the ketogenic diet program between 1994 and 2001. A subset of the cohort was also studied after 12 (n = 59) and 24 (n = 27) months. Intervention  A ketogenic diet consisting of a high ratio of fat to carbohydrate and protein combined (4:1 [n = 102], 3.5:1 [n = 7], or 3:1 [n = 32]). After diet initiation, the calories and ratio were adjusted to maintain ideal body weight for height and maximal urinary ketosis for seizure control. Main Outcome Measures  Differences at baseline and 6-month follow-up for levels of total, VLDL, LDL, HDL, and non-HDL cholesterol; triglycerides; total apoB; and apoA-I. Results  At 6 months, the high-fat ketogenic diet significantly increased the mean plasma levels of total (58 mg/dL [1.50 mmol/L]), LDL (50 mg/dL [1.30 mmol/L]), VLDL (8 mg/dL [0.21 mmol/L]), and non-HDL cholesterol (63 mg/dL [1.63 mmol/L]) (P<.001 vs baseline for each); triglycerides (58 mg/dL [0.66 mmol/L]) (P<.001); and total apoB (49 mg/dL) (P<.001). Mean HDL cholesterol decreased significantly (P<.001), although apoA-I increased (4 mg/dL) (P = .23). Significant but less marked changes persisted in children observed after 12 and 24 months. Conclusions  A high-fat ketogenic diet produced significant increases in the atherogenic apoB–containing lipoproteins and a decrease in the antiatherogenic HDL cholesterol. Further studies are necessary to determine if such a diet adversely affects endothelial vascular function and promotes inflammation and formation of atherosclerotic lesions.      

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.
