目的　研究血糖水平与脂质及载脂蛋白水平的关系。方法　对成都地区 735例 40～ 70岁男性空腹 12～ 14小时的血糖、血清甘油三酯 (TG)、胆固醇 (TC)、高密度脂蛋白胆固醇 (HDL- C)、低密度脂蛋白胆固醇(L DL- C)和血清载脂蛋白 (apo) A 、A 、B10 0、C 、C 及 E含量进行了测定。依空腹血糖的水平将受试对象分为正常组 (S1)、糖耐量减退组 (S2 )、糖尿病组 (S3)。结果　结果显示 :S2和 S3的高脂血症发病率比 S1高 (分别为64.5 %、45 .2 %和 32 .1% ) ;空腹 TG水平 S2 (3.62± 2 .5 2 mm ol/ L)和 S3(4 .45± 3.82 mmol/ L)均显著高于 S1(1.92± 1.93m mol/ L) ,P均 <0 .0 1;TC水平 S2 (5 .68± 1.15 mmol/ L)和 S3(5 .68± 1.12 m mol/ L)亦显著高于 S1(5 .13±1.0 6m mol/ L) ,P均 <0 .0 5 ;S2和 S3的血清 apo B10 0、C 、C 及 E水平显著高于 S1(P均 <0 .0 1或 P<0 .0 5 )。相关分析表明 ,血糖与血清 TG在 S1、S2和 S3中均呈显著正相关 (r分别为 0 .180 0、0 .1436和 0 .32 12 ) ,P均 <0 .0 0 1;而在 S2和 S3中血糖与 HDL- C呈负相关 (r分别为 - 0 .2 5 34和 - 0 .1477) ,P均 <0 .0 0 1;在 S1、S2、S3组中血糖与血清 apo B10 0、C 及 E呈正相关 (P均 <0 .0 0 1) ,与 apo C 则在 S1和 S2中呈正相关 (P<0     

维生素C对葡萄糖测定的干扰及其作用机制

（1）目的 探讨维生素C对葡萄糖测定的干扰及其作用机制。（2）方法 用葡萄糖氧化酶-过氧化物酶（GOD-PAP）法和己糖激酶（HK）法测定葡萄糖浓度。（3）结果 用GOD-PAP法测定葡萄糖浓度相同、维生素C浓度不同的系列溶液时,所测葡萄糖浓度随着维生素C浓度的增高而降低;用HK法进行测定时,所测葡萄糖浓度基本恒定,用GOD-PAP法测定不含葡萄糖的过氧化氢溶液时,葡萄糖表观浓度随着过氧化氢稀释度的增大而降低;当过氧化氢浓度相同时,葡萄糖表观浓度随着维生素C浓度的增高而降低。（4）结论 维生素C可能通过使区应的中间产物过氧化氢及最终产物苯醌亚胺还原而干扰GOD-PAP法对葡萄糖的测定结果。

目的 探讨胎膜早破患者羊水中葡萄及白介素－6(IL－6）含量与宫内感染的关系。方法 随机选择1994－1999年70例无妊娠并发症的胎膜早破的患者,在B超引导下,经腹行羊膜腔内穿刺,抽取羊水,用葡萄糖氧化酶方法测定水中葡萄糖,用酶联免疫方法测定IL－6含量。结果 胎膜早破并宫内感染者,羊水葡萄糖含量明显下降,IL－6含量则明显增高,当羊水葡萄糖含量≤0．55mmol/L,IL-6含量≥315ng/L时,预测宫内感染的敏感性100％,特异性＞80．00％。结论 胎膜早破患者,测定羊水葡萄糖及IL－6含量,能早期快速预测宫内感染。     

中药配方颗粒辅料麦芽糊精的HPLC定量检测与中红外光谱半定量检测

目的 建立中药配方颗粒辅料麦芽糊精的检测方法,为中药配方颗粒质量评价提供分析技术支持。方法 建立配方颗粒中果糖、葡萄糖、蔗糖、麦芽糖、乳糖的HPLC定量检测方法,根据样品经糖化酶水解后的葡萄糖增加量换算出麦芽糊精含量。基于中药浸膏与麦芽糊精不同比例混合物的中红外光谱（mid-infrared spectroscopy,MIRS）特征峰差异,建立配方颗粒中麦芽糊精的半定量检测方法。结果 所建立的HPLC方法可以准确定量检测配方颗粒中果糖、葡萄糖、蔗糖、麦芽糖、乳糖。如果中药浸膏自身含有较多可经糖化酶水解产生葡萄糖的成分（淀粉、蔗糖等）,HPLC检测配方颗粒中麦芽糊精时存在系统性正误差,可通过中药浸膏酶解后葡萄糖增加量、待测样品酶解后蔗糖减小量等部分修正正误差。如果中药浸膏自身少含或不含淀粉、蔗糖等可经糖化酶水解产生葡萄糖的成分,HPLC检测配方颗粒中麦芽糊精时存在系统性负误差,换算公式偏差、麦芽糊精纯度、样品处理损失等导致根据样品酶解后葡萄糖增加量计算的麦芽糊精“检测含量”预期低于根据生产投料计算的麦芽糊精“名义含量”。麦芽糊精含量越高,配方颗粒MIRS中1200～900 cm-1区域的...     

A randomized,double-blind placebo-controlled add-on trial to assess the efficacy,safety, and anti-atherogenic effect of spirulina platensis in patients with inadequately controlled type 2 diabetes mellitus

The efficacy of spirulina platensis (S. platensis) as an add-on therapy to metformin and its effect on atherogenic keys in patients with uncontrolled Type 2 Diabetes Mellitus (T2DM) was evaluated. Sixty patients were randomly assigned to S. platensis (2 g/day) or placebo group for three months while continuing metformin as their usual treatment. The efficacy of S. platensis was determined using the pre- and post-intervention HbA1c levels (primary outcome) as well as tracking FBS and lipid profiles levels (TC, LDL-C, TG, and HDL-C) as secondary outcomes at the different treatment time points (0,30,60,90 days). During the three–month intervention period, supplementation with S. platensis resulted in a significant lowering of HbA1c (↓1.43, p < 0.001) and FBS (↓ 24.94 mg/dL, p < 001) levels. Mean TG in the intervention group was found to be significantly lower in the intervention group than in controls (p < 0.001). Total cholesterol (TC) and its fraction, LDL-C, exhibited a fall (↓41.36 mg/dL and ↓38.4 mg/dL, respectively; p < 0.001) coupled with a marginal increase in the level of HDL-C (↑3 mg/dL; p < 0.001). Add-on therapy with S. platensis was superior to metformin regarding long-term glucose regulation and controlling blood glucose levels of subjects with T2DM. Also, as a functional supplement, S. platensis has a beneficial effect on atherogenic keys (TG and HDL-C) with no adverse events.

Neurogenic Obesity-Induced Insulin Resistance and Type 2 Diabetes Mellitus in Chronic Spinal Cord Injury

The population with SCI is at a significant risk for both insulin resistance and type 2 diabetes mellitus (T2DM) secondary to neurogenic obesity. The prevalence of insulin resistance and T2DM in persons with SCI suggests that disorders of carbohydrate metabolism are at epidemic proportions within the population. However, the true frequency of such disorders may be underestimated because biomarkers of insulin resistance and T2DM used from the population without SCI remain nonspecific and may in fact fail to identify true cases that would benefit from intervention. Furthermore, diet and exercise have been used to help mitigate neurogenic obesity, but results on disorders of carbohydrate metabolism remain inconsistent, likely because of the various ways carbohydrate metabolism is assessed. The objective of this article is to review current literature on the prevalence and likely mechanisms driving insulin resistance and T2DM in persons with SCI. This article also explores the various assessments and diagnostic criteria used for insulin resistance and T2DM and briefly discusses the effects of exercise and/or diet to mitigate disorders of carbohydrate metabolism brought on by neurogenic obesity.
