不同分娩方式对新生儿的影响

目的对两种分娩方式对新生儿质量的影响进行比较。方法选取我院2010年8月～2011年8月分娩的92例新生儿为研究对象。依分娩方式不同将其分为两组,每组46例。阴道分娩的新生儿为观察组;剖宫分娩新生儿为对照组。对两组研究对象的生活质量进行比较。结果观察组顺利分娩44例,分娩成功率95.7%,较对照组100%的成功率无显著差异性（P〉0.05）;观察组新生儿质量优于对照组（P〈0.05）。结论在确保母婴健康的前提下,阴道分娩用于产妇的分娩中能够改善新生儿质量,具有重要的临床价值。     

Role of adipocytokines and its correlation with endocrine pancreatic function in patients with pancreatic cancer

IntroductionSome authors suggest that adipocytokines contribute to the induction of pancreatic carcinogenesis as well as the development of endocrine insufficiency.AimsWe evaluate the circulating concentrations of leptin, resistin and visfatin in patients with newly diagnosed pancreatic cancer (PC) and relationship between serum adipocytokines level and clinicopathological features of PC. Moreover the usefulness of those adipocytokines as possible biomarkers of endocrine pancreatic function in PC has been assessed.MethodsThe pilot study group consisted of 45 individuals (mean age 65.6 ± 11.5 years, BMI 21.8 ± 3.4 kg/m²) with newly diagnosed PC (within last 1–3 months) and 13 healthy individuals with age, gender and BMI matched to the study group. Among PC patients 18 (40%) had recently diagnosed diabetes. Fasting plasma leptin, resistin, visfatin concentrations were determined with ELISA (R&D Systems, Phoenix Pharmaceuticals) and insulin by RIA (DakoCytomation).ResultsPatients with PC as compared to controls had significantly lower plasma leptin (40.6 ± 21.3 vs 63.2 ± 16.3 pg/mL; p < 0,0008). In contrast PC patients showed more than six fold higher level of resistin (126.2 ± 143.2 vs 18.9 ± 7.2 ng/mL; p < 0.009) than controls. The median plasma visfatin was 2.8 ± 1.8 ng/mL, which was not significantly different from the controls (3.8 ± 1.1 ng/mL). When PC patients with and without diabetes were considered separately, plasma leptin concentrations among nondiabetic patients were slightly, but not significantly higher (44.6 ± 21.0) as compared to diabetics (34.5 ± 20.7). Moreover there was no difference between visfatin and resistin level in PC, among patients with and without diabetes. No significant differences between serum level of leptin, visfatin and resistin and age, gender, BMI, smoking status, tumor localization, distant metastases and pain has been found.ConclusionThe results of this study confirm previous findings that patients with newly diagnosed pancreatic cancer are characterized with lower level of leptin. This pilot study showed significantly higher resistin concentrations in patients with PC in comparison to healthy controls, which may be helpful in PC early diagnosis. Changes in leptin and resistin level in PC are not likely related to endocrine disorders.     

短暂性脑缺血发作患者抵抗素水平的变化及其与纤维蛋白原的关系

目的研究短暂性脑缺血发作患者血清抵抗素水平的变化,及其与纤维蛋白原的关系,探讨其在短暂性脑缺血发作中的病理生理意义。方法短暂性脑缺血发作实验组、对照组取血,测定空腹血糖、血脂、胰岛素、纤维蛋白原水平,ELISA方法测定血清抵抗素水平。结果短暂性脑缺血发作组与正常对照组相比,血清抵抗素水平升高（P＜0.05）。多元logistic回归分析显示,血清抵抗素为短暂性脑缺血发作的独立危险因素,并与TIA病变程度呈正相关。抵抗素与纤维蛋白原水平呈正相关。结论抵抗素为短暂性脑缺血发作的独立危险因素,通过影响凝血系统参与短暂性脑缺血发作的病理生理过程,可用于评价病情严重程度,可作为缺血性脑血管病预防的新靶点。     

2型糖尿病患者血清抵抗素浓度与血脂代谢水平的临床意义

目的了解2型糖尿病患者血清抵抗素浓度与空腹血糖、血脂的关系。方法选择52例2型糖尿病患者和40例健康中老年人,分别分为糖尿病组和非糖尿病组,用竞争性酶联免疫吸附法测定各组空腹血浆抵抗素水平,同时检测空腹血糖、血脂各项指标。结果糖尿病空腹血浆抵抗素水平显著高于对照组(p<0.05)。抵抗素与甘油三脂、空腹血糖呈正相关关系(r=0.687,p<0.05,r=0.849,p<0.05),而抵抗素与其余各项血脂指标、性别之间无明显相关性。结论血清抵抗素水平与2型糖尿病关系密切,抵抗素水平可能影响体内能量代谢和平衡,与糖、脂代谢的关系更为密切。     

Comparison of Serum Levels and the Placental Expression of Resistin Between Patients with Preeclampsia and Normal Pregnant Women

Objective. The aim of this study was to evaluate serum resistin levels in women with preeclampsia compared to those in normal pregnant women and normal non-pregnant women, and to examine placental resistin expression. Methods. Serum resistin levels were measured by enzyme-linked immunosorbent assay and placental resistin expression was determined by immunohistochemistry. Results. Serum resistin levels were significantly elevated in women with preeclampsia compared to normal pregnant women and non-pregnant women. There was no significant difference in placental resistin expression. Conclusion. The placenta may not be the origin of the resistin that contributes to increased serum levels in women with preeclampsia.

清肝泻心滋阴润燥法对2型糖尿病患者脂肪细胞抵抗素及脂联素的影响

目的探讨清肝泻心滋阴润燥法对2型糖尿病患者血清脂肪细胞抵抗素及脂联素水平变化的影响及其与胰岛素抵抗的关系。方法入选患者随机分为治疗组30例,对照组30例,治疗组采用清肝泻心汤治疗,对照组采用文迪雅治疗2个月。用ELISA法检测并比较治疗前后两组的脂肪细胞抵抗素、脂联素的血清水平及其与血糖、胰岛素抵抗水平的关系。结果两组治疗后均能降低血糖(P<0.01),但两组间差值比较差异无显著性意义(P>0.05)。两组均能降低糖化血红蛋白,且治疗组明显优于对照组(P<0.01)。在改善胰岛素抵抗相关指标方面,两组治疗后均能降低胰岛素、C肽及血清抵抗素水平(P<0.01),升高胰岛素敏感性指数及脂联素水平(P<0.01),但两组间差值比较差异无显著性意义(P>0.05)。结论清肝泻心滋阴润燥法及文迪雅均能降低2型糖尿病患者血清抵抗素水平,升高脂联素水平,这些脂肪细胞因子的改变直接与2型糖尿病患者胰岛素抵抗的改善相关。     

瘦素、抵抗素、2型糖尿病间的相关性研究

目的：研究血浆瘦素与抵抗素、体重指数、腰围、腰臀比、血脂、胰岛素敏感性指数等的关系。方法：对43例新诊断2型糖尿病患者及37例糖耐量正常者，测定空腹血浆瘦素、胰岛素、血糖、血脂及抵抗素浓度。结果：相关分析显示性别、体重指数（BMI）、腰围、腰臀比、胰岛素与瘦素呈显著正相关（r分别为0.623,0.534，0.516，0.302，0.354，均P<0.01），IAI与瘦素呈显著负相关(r=-0.373,P<0.01),甘油三酯、胆固醇空腹血糖与瘦素无明显相关。瘦素与抵抗素无相关性（r=0.101,P>0.05）结论：空腹血浆瘦素水平与肥胖程度、胰岛素抵抗呈显著正相关，与抵抗素无关。瘦素可能与2型糖尿病的发病有关。
