Coronary artery disease in Chinese adults with type 2 diabetes mellitus estimated by electron beam computed tomography and electron beam computed tomography angiography

Objective To assess the prevalence and risk of coronary artery disease(CAD) in Chinese adults with type 2 diabetes mellitus(T2DM) using electron beam computed tomography(EBCT) and EBCT angiography(EBCTA) . Methods:Ninety-four cases were enrolled in this study including diabetes(n=28) ,impaired glucose tolerance(IGT,n=30) ,coronary heart disease(CHD,n=11) ,and control(n=25) . Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcifica-tion(CAC) scores,and number of segments of stenosed coronary arteries. Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions(CAL) . Results CAC scores were not different with the control,diabetes,IGT,or CHD(P>0.05) groups. Compared to control(0.520±1.295) ,more stenosed coronary arteries segments(P<0.05) were detected in diabetes(2.964± 1.915) ,IGT(2.200±2.024) ,and CHD(2.273±1.679) . Number of stenosed artery segments were correlated with age(r=0.215,P=0.019) ,postprandial glucose(r=0.224,P=0.015) ,total cholesterol(r=0.323,P=0.000) ,and duration of diabetes(r=0.208,P=0.004) . The incidences of CAL in diabetes(96.43%) ,IGT(93.33%) ,and CHD(90.91%) was substantially higher than that in normal control(56.00%,P<0.01) . The odds ratio of CAL associated with having diabetes was estimated to be 7.514(95% CI:1.885-63.778) . Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes,implying a high CAD risk. EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients.     

应用非线性混合效应模型法考察儿童疾病因素对环孢素药动学的影响

目的:考察疾病因素对于环孢素A(CsA)在儿童体内药动学的影响,促进个体化用药。方法:收集150例包括再生障碍性贫血(AA)、嗜血细胞综合征(HPS)和难治性肾病综合征(RNS)不同病种患儿的CsA血药浓度数据和临床资料。采用非线性混合效应模型法考察疾病种类因素对于CsA药动学的影响。采用Bayesian最大后验概率法获取并比较CsA在不同病种患者中药动学参数的差异。用拟合优度(goodness-of-fit)、自举法(bootstrap)、直观预测检验法(VPC)、正态化预测分布误差(NPDE)对最终模型的预测性能进行验证。结果:最终模型药动学参数的群体典型值分别为:吸收速率常数(k_a)1.22 h^-1,吸收时滞时间(T_lag)0.45 h,表观分布容积(V_d)218.18 L,口服清除率(CL)14.45 L·h^-1。拟合优度、自举验证、VPC和NPDE结果表明最终模型稳定,预测结果可靠。模型结构显示只有患者的体质量和AST值是影响CsA清除率的显著性因素。CsA在AA、HPS和RNS患者中的药动学参数差异无显著性(P>0.05)。结论:本研究成功获取了CsA在儿童AA、HPS和RNS患者中的药动学参数,上述疾病因素不会显著影响CsA在儿童体内的药动学过程。

Coalition of DNA polymorphisms of ApoB and ApoAI genes is related with coronary artery disease in Kazaks

Objective To explore the relationship between polymorphisms of XbaI and MspI loci of apolipoprotein B (ApoB) gene and -75 bp, +83 bp loci of apolipoprotein AI (ApoAI) gene and coronary heart disease (CHD) in Kazaks of Xinjiang Uyghur Autonomous Region, China. Methods These loci were analyzed by PCR-restriction fragment length polymorphism (PCR-PFLP). Two hundred and five patients with CHD and two hundred and thirty six controls were involved. Results There were significant distinctions among low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and the ApoAI/ApoB ratio between the two groups, but no significant distinction among the polymorphism frequencies of the four sites between the two groups. The polymorphism coalition frequency of X--/Ms++/M1+-/M2++ (named Coalition 11) was significantly higher in CHD compared to the control group (14.6% vs. 7.2%, P < 0.05). The level of total cholesterol (TC) in Coalition 11 was significantly higher and the level of the ApoAI/ApoB ratio in Coalition 11 was significantly lower than Coalition 1~10 in CHD patients. The level of the ApoAI/ApoB ratio of Coalition 11 was significantly lower than the Coalition 1~10 in control group. The levels of ApoAI/ApoB ratio of Coalition 3 were significantly higher compared to Coalition 11 in the two groups, respectively. The level of LDL-C of Coalition 3 was significantly lower than in the Coalition 11 in control group. The level of TC of Coalition 5 was significantly higher than Coalition 3 in the CHD group. The level of the ApoAI/ApoB ratio of Coalition 5 was significantly lower than in Coalition 3 or Coalition 1~10 of the two groups, respectively. The level of LDL-C of Coalition 5 was significantly higher than in Coalition 3 in control group. The ratio of ApoAI/ApoB was negatively related to TC, LDL-C and was positively related to HDL-C, both in CHD and control groups. Conclusion Coalition 11 of the 4 loci polymorphisms of the ApoB and ApoAI genes was correlated with CHD in Kazaks, and perhaps the ratio of ApoAI/ApoB was the most diagnostic parameter related with CHD among all lipid parameters. CHD may also be associated with Coalition 5, and, perhaps, Coalition 3 may have been confirmed as a protection factor against CHD, if more samples were enrolled.
