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。     

论《内经》中的“守神”“守机”“守气”

在针刺过程中,医者不能只拘守手部形式,针刺关键在于"治神"。治神是医者手法的核心,贯穿于整个施治过程中。以神"侯气"、"调气",进而"调神"、"调形体"。其理论在《内经》中已有叙述,具体包括:守神、守机和守气。这三者是对针灸医生针刺手法的要求,也是衡量针灸医生水平高低的标准之一。然而针道易陈而难入,针灸医生须认真钻研针刺手法和心法。针刺治神在于医者必须"心领神会",方能感悟。     

眼底动脉硬化与血压、血糖、血脂的多元分析与评估

目的探讨眼底动脉硬化与血压、血脂、血糖的相关性，评估中风危险度。方法对2004年5月至2008年10月就诊的患者335例，作为观察组，并与无症状的健康体检者180例作对照，动态检测眼底动脉硬化、血压、血糖、血脂的异常变化，并做综合量化评估。结果脑血管疾病与眼底动脉硬化、血压、血糖、血脂等因素密切相关。结论眼底动脉硬化、血糖、血脂、血压异常的量化评分，能够预估中风，以便采取预防性治疗。     

血液标本放置时间和抗凝剂对血糖检测结果的影响

目的 :探讨两种抗凝剂的血液标本放置时间对血糖测定的影响。方法 :采集门诊健康人血液标本 30份 ,分别以肝素钠和氟化钠作抗凝 ,放置不同时间检测血糖值。结果 :及时分离血浆的血液标本血糖在 5h内差异无显著性。而血液离体后不及时分离血浆 ,血糖是随着时间延长而降低。氟化钠抗凝的血糖比肝素钠抗凝的血糖下降的程度要缓慢一些 ,所以临床上采集血液标本必须及时分离血浆 ,选用合适的抗凝剂 ,及时测定 ,减少误差 ,提高准确性 ,给临床提供准确的诊断依据     

健脾活血方对2型糖尿病大鼠胰岛素抵抗的影响

目的:探讨健脾活血方对2型糖尿病胰岛素抵抗(Insulin Resistance,IR)的改善作用及机理。方法:取Wistar大鼠60只,雌雄各半,采用链脲佐菌素(Streptozotocin,STZ)加高脂饮食造成2型糖尿病IR大鼠模型,设空白组、模型组、健脾活血方组和罗格列酮组,以血糖仪检测大鼠空腹血糖(Fasting BloodGlucose,FBG),采用放射免疫分析法检测大鼠空腹胰岛素(Fasting Plasma Insulin,Fins),并计算胰岛素敏感性指数(Insulin SensitivityIndex,ISI)。用全自动生化检测仪检测游离脂肪酸(Free Fat Acid,FFA)。结果:健脾活血方能够调节血糖和胰岛素水平,降低血清FFA含量,提高ISI,其作用与罗格列酮相当,与模型组比较有显著性差异(P<0.05,P<0.01)。结论:健脾活血方对2型糖尿病大鼠IR有改善作用。     

A comparison of two rehabilitation protocols after total knee arthroplasty: does flexion affect mobility and blood loss?

We report a prospective trial comparing the effectveness of a post-operative flexion regime versus a standard extension regime on the early outcome and on the post-operative blood loss of total knee arthroplasty. Fourty-eight knees were divided to two different post-operative rehabilitation regimes: a flexion regime and an extension regime. The two groups were well matched with respect to age, gender, operation side and pre-op diagnosis All patients were implanted with a NexGen cemented total knee prosthesis and all operations were performed by the same surgeon. Patients were assessed pre-operatively, at the time of discharge, at 6 weeks and at 12 weeks, and were evaluated by means of the Knee Society Score (KSS) and the WOMAC score, the Clarkson criteria for range of motion and muscolar strength measurement, and the Verbal Numeric Scale (VNS) for the pain. Futhermore, postoperative blood loss was assessed by comparing the volume of blood in the drain at the time of their removal and measuring the difference in preoperative and postoperative blood haemoglobin (Hb) in the 2 groups. Patients subjected to the flexion regime had a better KSS and Womac score after 12 weeks and had less post-operative blood loss, requiring fewer blood transfusions. No differences were found between the two groups in terms of pain and muscolar strength. We believe a flexion regime after a total knee arthroplasty is a valid option of rehabilitation treatment and does not result in an increase in wound problems.     

瑞格列奈与迪沙片治疗新诊断2型糖尿病的疗效对比观察

比较对新诊断2型糖尿病患者应用瑞格列奈（11例）和迪沙片（10例）治疗4周后空腹血糖（FPG）、餐后2h血糖（2hPG）、晨3点血糖（3aPG）,空腹胰岛素（FIns）、餐后2h胰岛素（2hIns）,糖化白蛋白的值。结果显示,与迪沙片组相比,瑞格列奈组治疗后空腹血糖、餐后2h血糖的下降幅度更为明显,但低血糖的发生次数反而减少。     

Uncooked rice of relatively low gelatinization degree resulted in lower metabolic glucose and insulin responses compared with cooked rice in female college students

Cooking processes that gelatinize granules or disrupt structure might increase the glucose and insulin responses because a disruption of the structure of starch by gelatinization increases its availability for digestion and absorption in the small intestine. We hypothesized that the uncooked form of rice, which has a relatively low degree of gelatinization even though in powder form, would result in lower metabolic glucose and insulin responses compared with cooked rice (CR). To assess the effects of the gelatinization of rice on metabolic response of glucose and insulin, we investigated the glucose and insulin responses to 3 rice meals of different gelatinization degree in female college students (n = 12): CR (76.9% gelatinized), uncooked rice powder (UP; 3.5% gelatinized), and uncooked freeze-dried rice powder (UFP; 5.4% gelatinized). Uncooked rice powders (UP and UFP) induced lower glucose and insulin responses compared with CR. The relatively low gelatinization degree of UPs resulted in low metabolic responses in terms of the glycemic index (CR: 72.4% vs UP: 49.7%, UFP: 59.8%) and insulin index (CR: 94.8% vs UP: 74.4%, UFP: 68.0%). In summary, UPs that were less gelatinized than CR induced low postprandial glucose and insulin responses.     

化疗药物对轴型皮瓣血运影响的组织学观察

目的探讨抗癌药物动脉灌注后对局部轴型皮瓣血运影响的组织学评价。方法在猪腹部的腹壁上动脉插管灌注抗癌药物,10d后在猪腹部形成以腹壁上血管为蒂的岛状皮瓣,通过对灌注区域轴型血管供养的岛状皮瓣的成活率、光镜、透射电镜及血管铸型透明标本的组织学观察,显示其血管结构及构筑的变化。结果抗癌药物用于局部动脉灌注后,使局部轴型血管支配的血管网有损伤的表现,岛状皮瓣远端的血运显著降低。结论抗癌药物经动脉灌注后可影响局部轴型皮瓣的血运,使皮瓣血供的安全范围缩小,为提高相关修复手术的成功率提供可靠的科学依据。     

多部位采血快速血糖仪的临床应用

目的:探讨多部位采血快速血糖仪检测大鱼际毛细血管葡萄糖用于糖尿病患者血糖监测的准确性及优缺点。方法:对我科47例住院糖尿病患者在知情同意后进行血糖检测。行正常餐实验,在空腹时和正常餐后2h分别采静脉血用葡萄糖氧化酶法测定血糖、采手指血用乐康全血糖仪测定血糖、采手掌大鱼际血用Free- style多部位采血血糖仪检测血糖;同时进行采血疼痛感和使用方便性的主观调查,分最好、好、一般和差4级,转换为数字1、2、3、4进行评价。结果:3组的空腹血糖值差异无显著性(P>0.05);餐后2h血糖差异有显著性(P<0.05)。3组的空腹血糖及餐后2h血糖均有良好的线性相关(r=0.759～0.795,P<0.001)。3个部位的测试结果间均呈良好的线性相关,决定系数(R~2)=0.576～0.651(P<0.001)。两种血糖仪的使用方便性无明显差异.指尖采血的疼痛性要强于手掌大鱼际采血(P<0.05)。结论:多部位快速血糖仪(Freestyle)手掌大鱼际采血检测血糖的结果可靠,是糖尿病患者长期监测血糖的一种较为准确、方便、痛苦较少的方法。
