目的探讨糖尿病视神经病变与内皮型一氧化氮合酶(eNOS)基因第4内含子a/b多态性的关系。方法应用多聚酶链反应(PCR)方法检测正常人与2型糖尿病患者和糖尿病有视神经病变患者的eNOS基因a/b基因型,同时对上述患者的眼底及眼底荧光血管造影(FFA)等临床资料进行分析。结果糖尿病视神经病变组(DON)组a等位基因及aa+ab基因型频率显著高于正常对照组。因此eNOS基因27bpVNTR多态性与糖尿病视神经病变发生有关。结论一氧化氮参与了糖尿病视神经病变的发病。 相似文献

Objective To investigate the tendency of plasma levels of calcitonin gene-related peptide(CGRP)and endothelin(ET)in type 2 diabetic nephropathy,and explore the relationship between calcitonin gene-related peptide,endothelin and pathogenesis of diabetic nephropathy.Methods A total of 25 healthy controls(healthy control group)and 83 patients with type 2 diabetic mellitus(T2DM group)were enrolled in the investigation.According to level s of urinary albumin excretion rate(UAER),the 83 T2DM patients group were further divided into three subgroups:normal UAER subgroup(n=28),microalbuminuira subgroup(n=29)and clinical proteinuria subgroup(n=26).Plasma contents of calcitonin gene-related peptide and endothelin were measured with radioimmunoassay(RIA).Results The level of ET was significantly higher in T2DM group than that in healthy control group(P<0.01),positively correlative tO UAER(r=0.65,P<0.01).The plasma level of CGRP was significantly lower in the patients with diabetic nephropathy than the healthy controls,negatively correlative tO UAER(r=-0.71,P<0.01).There was negative correlation between plasma levels of ET and CGRP(r=-0.62,P<0.01).Conclusion The disequilibrium of CGRP and ET in plasma might play an important role in the process of diabetic nephropathy.Therefore,keeping balance of levels of CGRP and ET in plasma contributes to prevention and cure of diabetic nephropathy. 相似文献

目的探讨腺苷酸活化蛋白激酶(AMPK)ɑ2基因rs1124900G/T单核苷酸多态性与2型糖尿病(T2DM)及血清脂联素(adiponectin,APN)、颈动脉粥样硬化的关系。方法采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)的方法,收集2010年4-9月期间在本院内分泌科住院治疗的2型糖尿病患者178例,其中男性93例,女性85例,年龄(54.6±10.1)岁,对照组为同期本院体检的健康人员160例,男性84例,女性76例,年龄(51.8±9.8)岁,检测AMPK-rs1124900G/T基因型,分析2组人群之间基因型和等位基因频率的差异。同时测定身高、体质量、血压、血脂、APN、颈动脉内膜中层厚度(carotid intima-media thickness,CIMT)等。结果①在T2DM组G/G、G/T、T/T基因型频率分别为29.8%、43.2%、26.9%,T等位基因频率为48.6%。对照组G/G、G/T、T/T基因型频率为32.5%、42.5%、25.0%,T等位基因频率为46.3%,2组间无显著性差异(P>0.05)。②在T2DM组和对照组TT型者的血清TG、LDL-C水平明显高于GG型者,CIMT及斑块发生率显著高于GG基因型者,APN水平明显低于GG型者,差异有统计学意义(P<0.05)。③相关分析表明,CIMT及斑块发生率与血清TG(r=0.349 6,P<0.01)、LDL-C(r=0.416 7,P<0.01)正相关,与APN水平负相关(r=-0.262 3,P<0.05)。结论 rs1124900多态性位点与甘肃地区2型糖尿病的发生无关;与脂联素、TG、LDL、颈动脉内膜厚度及斑块有关。 相似文献

目的 通过对血糖控制理想的糖尿病患者进行动态血糖监测系统(CGMS)和指尖血糖监测,分析血糖数据,探讨CGMS是否更有利于血糖控制.方法 选择30例HbA1c达标的短期住院患者,进行72h的CGMS血糖监测,同时用指尖血糖监测3d的FBG、三餐后2hBG、睡前及凌晨3点血糖 ,记录血糖数据.结果 CGMS与指尖血糖监测相比,可以更广泛地监测到血糖最高值、最低值(P<0.01),提高高血糖、低血糖的检出率.通过调整治疗,可在短时间内使血糖达到24h的全面、平稳控制(P<0.05).结论 与指尖血糖监测相比,CGMS能够显示全面详细的血糖动态变化情况,较好地评估血糖漂移,为糖尿病患者制订更合理有效的防治策略提供科学依据. 相似文献
