2型糖尿病患者应用二甲双胍治疗前后血浆胃促生长素及YY肽水平

目的 观察二甲双胍治疗对新诊断2型糖尿病患者血浆胃促生长素、YY肽(PYY)水平的影响,探讨二甲双胍对2型糖尿病患者体重影响个体差异性的机制.方法 采用前瞻性巢式病例对照研究作为研究设计方案.64例新诊断2型糖尿病患者应用二甲双胍治疗12周,根据治疗后体重的变化情况,分为体重减轻组及体重未减轻组,治疗前后测定空腹血浆胃促生长素、PYY水平及相关代谢指标.结果 2型糖尿病患者经二甲双胍治疗后空腹血浆胃促生长素水平均较治疗前明显下降[(10.71 +2.68对11.81±3.19)ng/ml,P＜0.05],空腹血浆PYY水平均较治疗前明显升高[(136.86±39.14对128.42±37.31)pg/ml,P＜0.05].治疗后有43.7％的2型糖尿病患者出现体重明显下降.体重减轻组在治疗后空腹血浆胃促生长素水平下降16.6％,降幅高于体重未减轻组的6.2％(P＜0.05);体重减轻组在治疗后空腹血浆PYY水平升高10.8％,升幅高于体重未减轻组的3.5％(P＜0.05).结论 2型糖尿病患者二甲双胍治疗后体重明显减轻者较体重基本保持不变者,空腹血浆胃促生长素水平降低更显著,空腹血浆PYY水平升高更显著,具体机制还有待进一步研究.     

降糖药物对新发2型糖尿病患者胫前动脉弹性影响的初步探讨

目的 探讨降糖药物对新发2型糖尿病患者胫前动脉弹性的影响.方法 随机选取新发2型糖尿病患者100例,分为对照组50例和病例组50例.计算胫前动脉的应变-血压指数(SBPI),所有患者服用降糖药物6个月后再次计算胫前动脉的SBPI,并进行组间和组内对比分析.结果 对照组胫前动脉SBPI治疗后高于治疗前(P<0.05).病例组胫前动脉SBPI治疗前后比较差异无统计学意义(P>0.05).病例组胫前动脉SBPI在治疗前和治疗后均低于对照组(P<0.05).结论 降糖药物对不合并血管并发症的新发2型糖尿病患者胫前动脉弹性有较好的保护作用.

Abstract：

Objective To investigate the effects in elasticity of anterior tibial artery in new patients with type 2 diabetes caused by medicines of reducing blood sugar. Methods One hundred patients with type 2 diabetes were involved. The patients were divided into control group(50 cases) and case group(50 cases) according the vascular complications (including macroangiopathy and microangiopathy). Maxmum of circumferential strain(CSmax) of anterior tibial artery was acquired through strain and strain rate imaging. Local blood pressure which included local systolic blood pressure(LSBP) and local diastolic blood pressure (LDBP) of anterior tibial artery was measured at the same time. Strain-blood pressure index(SBPI) of anterior tibial artery was calculated, SBPI = CSmax/[(LSBP - LDBP)/LDBP] × 100%. It took six months for each patient to take medicines of reducing blood sugar. Then SBPI of anterior tibial artery was calculated again. Parameters were compared inter- and intra-groups. Results SBPI of anterior tibial artery after therapy was higher than that before therapy in control group( P<0. 05). There was no significant difference between SBPI of anterior tibial artery before therapy and that after therapy in case group( P >0. 05). SBPI of anterior tibial artery in case group was lower than that in control whatever before and after therapy( P < 0. 05). Conclusions The protection of medicines of reducing blood sugar on elasticity of anterior tibial artery in new diabetic patients without vascular complications was better.     

抗甲状腺药物致粒细胞缺乏症临床分析

目的：总结抗甲状腺药物（ATD）引起粒细胞缺乏症（粒缺）的临床特点=治疗措施及ATD引起粒缺的危险因子。方法：对12例由ATD引起的粒缺的临床资料作一回顾性分析。结果：11例由服用他巴唑（MM）引起,1例由服用丙基硫氧嘧啶（PTU）引起,多于服药后3-8周发病,粒细胞集落刺激因子（G-CSF）能显著缩短体温恢复正常的时间及粒细胞恢复正常的时间。结论：MM可能比PTU更易引起粒缺,对服用ATD者均应常规监测白细胞,G-CSF对ATD引起的粒缺治疗有效。     

急性时相蛋白和IL-6及TNF-α与2型糖尿病肾病的关系

目的探讨2型糖尿病肾病不同阶段血清急性时相蛋白和白细胞介素6(IL-6)以及肿瘤坏死因子α(TNF-α)水平的变化及其意义。方法符合1999年WHO糖尿病诊断标准的2型糖尿病(T2DM)患者105例,按尿白蛋白排泄率(UAER)分为正常蛋白尿组(NA组)34例、微量白蛋白尿组(MA组)31例、临床蛋白尿组(CP组)30例,并以33例健康体检者作为正常对照组(NC组)。免疫散射比浊法测定血清急性时相蛋白包括C反应蛋白(CRP)、α1-酸性糖蛋白(α1-AAG)、铜蓝蛋白(CER)和触珠蛋白(THP)水平,电化学发光法测定IL-6及TNF-α水平。结果⑴T2DM患者血清急性时相蛋白和IL-6及TNF-α水平明显高于NC组(P<0.05或P<0.01)。⑵血清急性时相蛋白和IL-6及TNF-α水平随着UAER的增加而增加(P<0.05或P<0.01)。⑶MA组及CP组患者,血清急性时相蛋白与IL-6及TNF-α呈正相关(P<0.05或P<0.01)。结论T2DM肾病存在急性时相反应,炎症反应强度与肾病的严重程度有关,急性时相反应强度与IL-6及TNF-α水平相关。
