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.     

成都地区437例健康男性中老年人血清载脂蛋白CⅡ,CⅢ及E水平分析

Apolipoprotein (apo) C II, C III and E levels of 437 male healthy subjects aged 40-70 [with fasting serum triglyceride (TG levels < 2.26 mmol/L, total cholesterol (TC) levels < 6.21 mmol/L and plasma glucose levels < 6.10 mmol/L] in Changdu area were determined by radial immunodiffusion assay (RID). The results showed that the concentrations of apoC II, C III and E were 41.6 +/- 13.1, 112.8 +/- 31.0 and 38.7 +/- 8.2 mg/L (mean +/- s) respectively. No difference in the serum levels of apoC II, C III and E was noted between the men of different ages. The results of the linear correlation showed that there was a positive correlation of apoC II, C III, E with TG, TC, LDL-C; of apoC II, C III with BMI; and of apoE with ages.

Apolipoprotein C III gene Sst I polymorphism in patients with endogenous hypertriglyceridemia in Chinese population]

OBJECTIVE: To investigate the apoC III gene Sst I polymorphism and its relationship with serum lipids and apolipoproteins (apo) levels in patients with endogenous hypertriglyceridemia in Chinese population. METHODS: The genotype and allele frequency of apoC III gene Sst I polymorphism was assayed by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). Serum lipids were measured by enzymatic kits and apolipoproteins A I, A II, B100, C II, C III and E were measured by RID kits developed by Apolipoprotein Research Unit of WCUMS in 176 HTG patients whose fasting serum TG levels were > or = 2.26 mmol/L and in 199 healthy subjects whose fasting serum TG levels were < 1.82 mmol/L and TC levels < 6.2 mmol/L from a population of Chinese Han nationality in Chengdu area. RESULTS: In both HTG group and control group, S1 allele was the major allele and homozygous S1S1 genotype was the most frequent one. The frequency of S2 allele was significantly higher than that reported in Caucasians (0.289 vs 0.06-0.16, P < 0.05). No differences were found in apoC III gene Sst I polymophism in the HTG group when compared with the control group (0.287 vs 0.289, P > 0.05). The genotype of S2S2 was not associated with higher TG and apolipoproteins levels when compared with the genotypes of S1S1 and S1S2 (P > 0.05). CONCLUSION: These results suggest that the Sst I polymorphism of the apoC III gene was not associated with endogenoushypertriglyceridemica in Chinese population.

Effect of surgical castration on risk factors for arteriosclerosis of patients with prostate cancer

Objective To analyze the effect of castration on risk factors for arteriosclerosis of patients with prostate cancerMethods Thirty patients with primary regional prostate adenocarcinoma limited to the prostate theca were selected in this study.Serum levels of testosterone (T), free testosterone (FT), dehydroepiandrosterone (DHEA), sex hormone-binding globulin (SHBG), prostatic specific antigen (PSA), triglyceride (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), apoprotein α(1) (APOα(1)) and apoprotein β (APOβ), insulin, plasma fibrinopeptide A (FPA), plasminogen activator inhibitor-1 (PAI-1) and fibrinogen were determined just prior to, 1 week and 1, 4 and 8 months after castration.Results T, FT and PSA decreased significantly 1 week after castration (21.12±15.11 ng/ml vs 383.9±62.6 ng/ml, P&lt;0.001; 4.08±3.29 pmol/L vs 34.11±11.59 pmol/L, P&lt;0.001; 14.34±7.77 ng/ml vs 23.51±6.57 ng/ml, P=0.001, respectively) and continued to decrease until reaching their lowest levels 8 months after castration.DHEA and SHBG did not undergo any changes.TG, fasting insulin and glucose, 2-hour insulin and glucose levels were significantly elevated 1 month after castration (1.84±0.61 mmol/L vs 1.30±0.40 mmol/L, P&lt;0.05; 18.16±5.57 mU/L vs 9.47±3.81 mU/L, P&lt;0.05; 4.77±0.66 mmol/L vs 3.92±0.34 mmol/L, P&lt;0.05; 65.52±14.78 mU/L vs 36.94±17.12 mU/L, P&lt;0.01; 6.98±0.79 mmol/L vs 6.01±0.23 mmol/L, P=0.001, respectively).TC, LDL-C, FPA and PAI-1 levels were elevated 4 months after castration (6.56±0.99 mmol/L vs 5.29±0.75 mmol/L, P&lt;0.01; 4.09±0.86 mmol/L vs 3.04±0.15 mmol/L, P&lt;0.01; 3.39±1.67 nmol/L vs 1.48±0.50 nmol/L, P&lt;0.01; 27.02±5.98 ng/ml vs 21.78±3.16 ng/ml, P&lt;0.05, respectively), continuing to increase after that point.Insulin sensitive index (ISI) decreased significantly 1 month after surgery (-4.42±0.36 vs -3.50±0.39, P&lt;0.001), and continued to decrease from that point forward.HDL-C, APOα(1), APOβ and fibrinogen remained at pre-operative levels.There was a negative linear correlation between FT and TG, TC, LDL-C, PAI-1, FPA, fasting insulin and glucose, 2-hour insulin and glucose (r=-0.311, -0.384, -0.385, -0.339, -0.353, -0.381, -0.303, -0.460 and -0.395, respectively; P&lt;0.05).A similar phenomenon occurred with T (r=-0.308, -0.309, -0.356, -0.320, -0.430, -0.453, -0.435, -0.483 and -0.512, respectively; P&lt;0.05).T and FT were positively associated with ISI (r=0.555 and 0.501; P&lt;0.001).Conclusions At 8 months follow-up of the study subjects, we found that lower androgen levels have adverse effects on lipid metabolism, coagulative function and insulin sensitivity, related to arteriosclerosis in men.

上海地区中国人餐后血糖状态的特征

目的探讨正常糖调节(NGR)及2型糖尿病(T2DM)个体餐后血糖状态的特征以及T2DM患者餐前、餐后血糖与糖化血红蛋白(HbA1c)的关系。方法采用动态血糖监测系统对上海地区41例NGR及60例新诊断T2DM个体进行连续3d的血糖监测,分析比较餐后血糖峰值与达峰时间,以及餐后血糖漂移的幅度(PPGE)、时间和曲线下面积增值(IAUC)。结果(1)三餐后血糖峰值、达峰时间及PPGE在T2DM组(早餐16·45mmol/L±0·43mmol/L、93·1min±4·7min、6·84mmol/L±0·28mmol/L,中餐14·75mmol/L±0·50mmol/L、107·4min±6·5min、4·93mmol/L±0·31mmol/L,晚餐14·91mmol/L±0·45mmol/L、109·3min±4·9min、5·84mmol/L±0·28mmol/L)显著高于NGR组(早餐6·90mmol/L±0·21mmol/L、40·8min±2·9min、2·02±0·17mmol/L,中餐6·74mmol/L±0·16mmol/L、43·7min±3·1min、2·03±0·12mmol/L,晚餐6·94mmol/L±0·19mmol/L、53·5min±3·8min、2·25mmol/L±0·18mmol/L,均P<0·01)。日内餐后血糖漂移时间及IAUC在T2DM组(14·1h±0·3h,2·04mmol·L-1·d±0·09mmol·L-1·d)亦显著高于NGR组(8·3h±0·4h,0·43mmol·L-1·d±0·03mmol·L-1·d,均P<0·01)。(2)T2DM组早餐后血糖较快达到尖峰(P<0·05),且峰值显著高于中、晚餐(P<0·01),PPGE从高到低的顺序分别为早、晚及中餐(P<0·05),晚餐的IAUC显著高于早、中餐(P<0·01)。(3)HbA1c与IAUC的相关性(r=0·29,P=0·03)在调整餐前血糖的因素后消失(P=0·05);PPGE与IAUC呈显著正相关(r=0·93,P<0·01)。(4)T2DM组餐后血糖对总体日内血糖的贡献百分比显著高于NGR组(18·1%±0·8%比8·0%±0·7%,P<0·01),但均显著低于其餐前血糖(P<0·01)。(5)当HbA1c<7·5%时,餐后血糖升高部分对总体日内高血糖的贡献大于餐前血糖(P<0·05),当HbA1c≥7·5%时,餐前高血糖的相对作用逐渐增加并占主要作用(P<0·01)。结论(1)T2DM患者表现为餐后血糖的过度漂移并持续较长时间,同时伴有血糖尖峰的延迟,其餐后急性高血糖状态以早餐最明显。(2)HbA1c不能反映餐后血糖的漂移变化,PPGE可作为估测餐后血糖漂移程度的简易临床参数。(3)在轻、中度高血糖的患者中,餐后高血糖起主要作用,提示血糖控制越接近达标,餐后血糖的控制越重要。
