目的探讨抵抗素和脂联素与妊娠期高血压疾病(HDCP)的关系及其在发病过程中的作用。方法以100例妊娠期高血压疾病孕妇为观察组,其中轻度子痫前期69例,重度子痫前期31例;选取同期100例正常孕晚期孕妇为对照组。采用酶联免疫吸附法(ELISA法)检测孕妇血清抵抗素和脂联素水平,同时检测空腹血糖(FBG)水平、空腹胰岛素(FINS)水平,计算胰岛素抵抗指数(IRI)。结果随病情进展血清脂联素水平逐渐下降,而抵抗素水平逐渐升高,差异有统计学意义(P<0.01)。轻度、重度子痫前期患者血清抵抗素水平与胰岛素抵抗指数呈现显著正相关(r=0.805、r=0.819,P<0.01),脂联素水平与胰岛素抵抗指数呈现显著负相关(r=-0.784、r=-0.795,P<0.01),抵抗素与脂联素水平呈现显著负相关(r=-0.845、r=-0.858,P<0.01)。结论抵抗素和脂联素在HDCP的发病过程中起着相反的作用,抵抗素的致病作用和脂联素保护作用可能是通过改变胰岛素抵抗实现的,二者有望成为临床预测HDCP发病及严重程度的指标。  相似文献

Background Many researches suggested that obesity increased the risk of breast cancer, but the mechanism was currently unknown. Adipocytokines might mediate the relationship. Our study was aimed to investigate the relationship between serum levels of resistin, adiponectin and leptin and the onset, invasion and metastasis of breast cancer. Methods Blood samples were collected from 80 newly diagnosed, histologically confirmed breast cancer patients and 50 age-matched healthy controls. Serum levels of resistin, adiponectin and leptin were determined by enzyme-linked immunosorbent assays (ELISA); fasting blood glucose (FBG), lipids, body mass index (BMI), and waist circumference (WC) were assayed simultaneously.Results Serum levels of adiponectin ((8.60±2.92) mg/L vs (10.37±2.81) mg/L, P=0.001) and HDL-c were significantly decreased in breast cancer patients in comparison to controls. Serum levels of resistin ((26.35±5.36) μg/L vs (23.32±4.75) μg/L, P=0.000), leptin ((1.35±0.42) μg/L vs (1.06±0.39) μg/L, P=0.003), FBG and triglyceride (TG) in breast cancer patients were increased in contrast to controls, respectively. However, we did not find the significant difference of the serum levels of resistin, adiponectin and leptin between premenopausal breast cancer patients and healthy controls (P=0.091, 0.109 and 0.084, respectively). The serum levels of resistin, adiponectin and leptin were significantly different between patients with lymph node metastasis (LNM) and those without LNM (P=0.001, 0.000 and 0.006, respectively). The stepwise regression analysis indicated that the tumor size had the close correlation with leptin (R(2)=0.414, P=0.000) and FBG (R(2)=0.602, P=0.000). Logistic regression analysis showed that reduced serum levels of adiponectin (OR: 0.805; 95%CI: 0.704–0.921; P=0.001), HDL (OR: 0.087; 95%CI: 0.011–0.691, P=0.021), elevated leptin (OR: 2.235; 95%CI:1.898–4.526; P=0.004) and resistin (OR: 1.335; 95%CI: 1.114–2.354; P=0.012) increased the risk for breast cancer; Reduced serum levels of adiponectin (OR: 0.742; 95%CI: 0.504–0.921; P=0.003) and elevated leptin (OR: 2.134; 95%CI:1.725–3.921; P= 0.001) were associated with lymph node metastasis of breast cancer. Conclusions The decreased serum adiponectin levels and increased serum resistin and leptin levels are risk factors of breast cancer. The low serum adiponectin levels and high serum leptin levels are independent risk factors for metastasis of cancer. The association between obesity and breast cancer risk might be explained by adipocytokines.  相似文献

Background Hyperinsulinemic euglycemic clamp is the gold standard to evaluate the insulin sensitity, but it is too complicated and expensive to use in clinic.We tried to find an alternative indicator to reflect insulin sensitivity.To evaluate the association between the four adipokines, adiponectin, leptin, resistin and tumor necrosis factor-α (TNF-α) with insulin sensitivity, we used a hyperinsulinemic euglycemic clamp to test insulin sensitivity in Chinese patients with obesity and type 1 or type 2 diabetes mellitus versus controls.Methods In this parallel control study, we tested insulin sensitivity using a hyperinsulinemic euglycemic clamp in different groups, then examined levels of adiponectin, leptin, resistin and TNF-α in serum, and the relationship between the different adipokines and glucose disposal rate (M value), as well as insulin sensitivity index (M value/insulin, M/I),which are the "gold standard" indices of insulin sensitivity.Results There were significant differences in mean leptin values in the four adipokines from the four different groups (P〈0.001; comparison of the variation between different groups was analyzed by variance analysis).Compared to controls (using multiple comparison two-way Dunnett t test), only the leptin level showed significant differences in the four adipokines from the four different groups at the same time (P 〈0.001).The association analysis between the different adipokines and M or M/I values also showed that only leptin negatively correlated with M (r=-0.64, P 〈0.001) or M/I values (r=-0.56, P〈0.001); there was no relationship between the other three adipokines and M or M/I values.Conclusion Only leptin was associated with M or M/I values.Therefore, leptin might be one of the predictive factors of the degree of insulin resistance and risk of the accompanying disease.  相似文献

[目的] 研究脂联素、瘦素、抵抗素水平对高血压前期及其中医辨证分型的影响,并探讨其水平与年龄、体重指数、收缩压、舒张压、平均动脉压的相关性。[方法] 纳入初诊为高血压前期组受试者79 例,其中肝火亢盛型20 例、阴虚阳亢型18例、痰湿壅盛型22 例、阴阳两虚型19 例,同时纳入理想血压健康体检组受试者15 例为对照组。分别测定上述受试者空腹血清脂联素、瘦素、抵抗素水平,并进行统计分析。[结果] 1)高血压前期组空腹血清脂联素显著低于对照组(P<0.01),空腹血清瘦素、抵抗素水平显著高于对照组(P<0.01)。2)痰湿壅盛型受试者脂联素水平低于其他3 个证型(P<0.05),瘦素、抵抗素水平高于其他3 个证型(P<0.05),肝火亢盛、阴虚阳亢、阴阳两虚3 个证型经两两比较差异无统计学意义(P>0.05)。3)在高血压前期组中,脂联素水平与收缩压和平均动脉压呈负相关,瘦素与收缩压、舒张压和平均动脉压呈正相关,抵抗素与上述指标无相关性。在对照组中瘦素与年龄、收缩压、舒张压和平均动脉压呈正相关,脂联素、抵抗素与上述指标无明显相关性。[结论] 1)高血压前期组较理想血压组脂联素水平下降,并且瘦素、抵抗素水平升高,且与血压水平有不同程度的相关性,说明脂肪组织可能参与了高血压前期的发生。2)痰湿壅盛型受试者脂联素水平低于其他3 个证型,而瘦素、抵抗素水平高于其他3 个证型,说明脂肪组织的内分泌功能可能影响高血压前期的中医辨证分型,或可成为高血压前期中医辨证分型的客观指标之一。3)对脂肪组织内分泌功能的干预或可成为预防高血压前期发生乃至发展为临床高血压的有效途径。  相似文献

In this study, serum adiponectin and resistin levels were determined in 46 patients with polycystic ovarian syndrome (PCOS), and their correlation with serum sexual hormones and insulin resistance (IR) were examined.The subjects included 26 obese patients with body mass index (BMI)>25 and 20 non-obese patients with BMI≤25, with 25 obese and 25 non-obese healthy volunteers without PCOS serving as controls.Serum adiponectin and resistin levels in all subjects were measured, and endocrinal and metabolic indices were also analysed.Our results showed that the serum adiponectin levels in both obese and non-obese PCOS groups were significantly lower than their controls, while the serum resistin levels in obese and non-obese PCOS group were significantly higher than in their controls (P<0.001).The serum adiponectin level was significantly lower and serum resistin level significantly higher in the non-obese PCOS group as compared with the obese control group (P<0.05).Serum adiponectin level was negatively correlated with FIN, HOMA-IR, LH and LH/FSH (P<0.05), but serum resistin level was positively correlated with FIN, HOMA-IR, LH and LH/FSH (P<0.05).We are led to conclude that PCOS patients have obvious IR, low serum adiponectin and high serum resistin, and adiponectin and resistin might play important roles in the pathogenesis of IR in PCOS patients.  相似文献

Objective: To explore the serum levels of resistin and adiponectin in patients with overweight and obesity. Methods: Fifty-eight cases with normal weight and 24 patients with overweight and obesity have taken fasting blood samples for measurements of plasma glucose, plasma lipids, insulin, C-peptide, thyroid hormones, C-response protein, interleukin-6, TNF-α, leptin, adiponectin and resistin. Results: The concentrations of resistin in cases with overweight and obesity were significant higher than those in the normal weight cases (16. 01 ± 8. 60 vs 11. 63 ± 9. 05 ng/ml, P = 0. 047). Pearson relation analysis showed that serum resistin concentrations were positively correlated with age (r= 0. 476, P = 0.019), but negatively correlated with C-peptide (r=-0.45, P=0. 024), and adiponectin concentrations were positively correlated with HDL-c (r=0. 463, P=0. 023) and systolic blood pressure (r=0. 409, P=0. 047) in overweight and obesity cases. Conclusion: The concentrations of resistin in cases with over-weight and obesity are higher, and there is no correlation between resistin and blood glucose, blood lipids and insulin, while the serum adiponectin concentrations positively correlated with HDL-c and systolic blood pressure.  相似文献
