目的探讨代谢综合征患者胰岛素抵抗与冠状动脉病变的关系。方法对2009年1月至2010年7月期间至我科就诊的137例存在发作性胸痛症状,临床怀疑冠心病的患者按照代谢综合征诊断标准分为代谢综合征组和非代谢综合征组。对上述病例进行冠状动脉造影,同时测他们的胰岛素抵抗指数。将上述结果进行组内及组间统计学分析。结果代谢综合征组中胰岛素抵抗指数与病变类型的比较表明,代谢综合征组B型及C型病变的发生例数明显增多。胰岛素抵抗指数与冠状动脉病变严重程度之间明显相关。非代谢综合征组虽然也有类似趋势但统计学无明显差异。结论胰岛素抵抗指数可以作为预测代谢综合征患者合并冠状动脉粥样硬化性心脏病患者冠状动脉病变严重程度的预测指标。 相似文献

Atherosclerosis and insulin resistance are common complications of adult growth hormone deficiency (GHD) and acromegaly. Circulating adiponectin, an adipocyte-derived protein, has both anti-atherogenic and insulin-sensitising effects. In this study, we measured serum adiponectin levels in patients with either adult GHD or acromegaly to clarify the impact of GH secretory states on the regulation of serum adiponectin levels. Serum adiponectin level was measured by radioimmunoassay in 32 patients with adult GHD, 49 patients with acromegaly and 25 normal subjects. The relationships between adiponectin and insulin sensitivity index assessed as quantitative insulin sensitivity check index (QUICKI), BMI, and serum GH and IGF-I levels were then investigated. The values of QUICKI were significantly lower in patients with acromegaly or adult GHD compared to normal subjects (0.33 +/- 0.03, P < 0.01, 0.35 +/- 0.04, P < 0.05 and 0.36 +/- 0.01, respectively). While patients with adult GHD had significantly lower serum adiponectin levels than patients with acromegaly (6.5 +/- 3.9, 9.2 +/- 5.0, P < 0.01) these levels were not significantly different from those found in normal subjects (7.8 +/- 4.3 mug/ml). There was an inverse correlation between serum adiponectin levels and BMI in both patient groups (GHD r = -0.39, P < 0.05; Acromegaly r = -0.35, P < 0.05). However, serum adiponectin levels correlated positively with QUICKI (R(s) = 0.37, P < 0.05) only in patients with adult GHD. In patients with acromegaly, the levels of circulating adiponectin showed an inverse correlation with serum IGF-I levels (R(s) = -0.34, P < 0.05), but not with basal GH levels. These results demonstrate that adiponectin levels are significantly lower in patients with adult GHD than in patients with acromegaly. Adiponectin levels are similar in patients with GHD and healthy controls, whereas in patients with acromegaly, insulin resistance appears to be not closely related to adiponectin levels compared with BMI. The different relationship between adiponectin and QUICKI observed in the adult GHD and acromegaly groups presumably reflects differences in the mechanisms of insulin resistance under states of GH deficiency or excess. 相似文献

Three measures of tumor necrosis factor alpha activity and insulin resistance in nonobese Japanese type 2 diabetic patients 总被引:3,自引:0,他引:3
Ohya M Taniguchi A Fukushima M Nakai Y Kawasaki Y Nagasaka S Kuroe A Taki Y Yoshii S Hosokawa M Inagaki N Seino Y 《Metabolism: clinical and experimental》2005,54(10):1297-1301
The aim of the present study was to investigate the relationship between insulin resistance and tumor necrosis factor alpha (TNF-alpha) as well as soluble TNF receptors (sTNF-R), body mass index (BMI), leptin, adiponectin, and serum lipid profile including triglycerides in nonobese Japanese patients with type 2 diabetes. A total of 88 nonobese Japanese type 2 diabetic patients were studied. The duration of diabetes was 11.0 +/- 0.8 years. In conjunction with BMI, glycosylated hemoglobin (HbA1c), fasting concentrations of plasma glucose, serum lipids (triglycerides, high-density lipoprotein cholesterol, and total cholesterol), serum leptin, serum adiponectin, serum TNF-alpha, and soluble TNF receptors (sTNF-R1 and sTNF-R2) were also measured. Insulin resistance was estimated by the insulin resistance index of homeostasis model assessment. Insulin resistance was positively correlated with BMI, triglycerides, leptin, and total cholesterol and negatively correlated with adiponectin and high-density lipoprotein cholesterol. In contrast, insulin resistance was not associated with TNF-alpha, nor sTNF-R (sTNF-R1 and sTNF-R2) in our diabetic patients. There was no significant relationship between the 3 measures of TNF-alpha system (TNF-alpha, sTNF-R1, and sTNF-R2) and BMI, serum triglycerides, leptin, or adiponectin in these patients. From these results, it can be concluded that peripheral levels of TNF-alpha system activity are not a major factor responsible for insulin resistance in nonobese Japanese type 2 diabetic patients. 相似文献

AIM: To investigate the roles of the adipocytokines, ghrelin and leptin in gastric cancer cachexia.
METHODS: Resistin, ghrelin, leptin, adiponectin, insulin and insulin-like growth factor (IGF-Ⅰ), were measured in 30 healthy subjects, and 60 gastric cancer patients of which 30 suffered from cancerinduced cachexia and 30 served as a control group. The relationships between hormones, body mass index (BMI) loss ratio, age, gender, and Glasgow Prognostic Score (GPS) were investigated.
RESULTS: Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients (P 〈 0.05). Ghrelin, resistin, leptin, adiponectin and IGF- Ⅰ, showed a significant correlation with BMI loss ratio and GPS (P 〈 0.05). A strong correlation was seen between GPS and BMI loss (R = -0.570, P 〈 0.0001). Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin, resistin, leptin and IGF-Ⅰ (P 〈 0.05). Existence of an important significant relationship between resistin and insulin resistance was also noted.
CONCLUSION: These results showed that serum ghrelin, leptin, adiponectin, and IGF-Ⅰ play important roles in cachexia-related gastric cancers. No relationship was found between resistin and cancer cachexia. Also, because of the correlation between these parameters and GPS, these parameters might be used as a predictor factor. 相似文献

Adiponectin, an adipocyte-derived protein, predicts future insulin resistance: two-year follow-up study in Japanese population 总被引:12,自引:0,他引:12

It has been reported that the serum adiponectin level was negatively correlated with body mass index (BMI), insulin resistance index, and triglycerides and was positively correlated with high-density lipoprotein cholesterol in several cross-sectional studies. However, the causal relationship has not been elucidated. We investigated whether the baseline adiponectin level could predict subsequent changes in insulin resistance, lipid profile, or body weight in a 2-yr longitudinal study. This study included 590 male Japanese subjects, aged 30-65 yr, who received annual health checkups in both 2000 and 2002. Blood pressure, heart rate, and anthropometric and metabolic parameters, including serum insulin and adiponectin levels, were determined. The insulin resistance index was calculated based on homeostasis model assessment. Baseline adiponectin level was not correlated with the subsequent change in lipid profile or BMI in 2 yr after adjustment for each baseline value. However, the baseline adiponectin level was negatively correlated with subsequent changes in insulin and insulin resistance index based on homeostasis model assessment, even after adjustment for change in BMI (r = -0.162 and r = -0.140, respectively). These findings suggest that the serum adiponectin concentration predicts subsequent changes in insulin resistance, but not in lipid profile or body weight. 相似文献
