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。     

The shape of stress: the use of frequent sampling to measure temporal variation in S‐IgA levels during acute stress

Previous studies have indicated that statistically significant increases in Secretory immunoglobulin A (S‐IgA) can be achieved in as little as 5min as a result of mental stress. However, the temporal resolution of these changes is low and therefore the rate and pattern of changes during the stress task and during subsequent recovery is unclear. A within‐subjects design was used to examine levels of S‐IgA before, during and after a short (8 min) mental stress task. S‐IgA was measured from saliva samples obtained every 2 min during the entire 30‐min session. Significant increases in S‐IgA concentration were observed as early as the task instruction period, with additional increases during the stress task itself. The data also show a rapid recovery of S‐IgA, with a return to baseline levels within 6 min. Results suggest that S‐IgA changes can occur very rapidly and that the observed increases are short‐lived.

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。

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。     

神经移植重建面神经在腮腺癌根治术中的应用

目的：探讨腮腺深叶癌切除面神经后，即刻功能性修复的临床效果。方法：对1984年1月至2005年10月间收治的11例腮腺癌患者，术中采用将肿瘤连同腮腺及面神经切除，同时行颈丛神经移植重建面神经的治疗方法。结果：术后面神经功能均完全恢复，所有患者术后6个月复诊，见患者静态时面部对称，动态时口角轻度偏斜，术后一年两侧面部完全对称，睁、闭眼及提口角功能基本恢复正常。结论：腮腺癌根治术中采用颈丛神经移植能有效地恢复面神经的功能，既达到肿瘤切除的彻底性，又符合功能外科的发展要求，是一种比较理想的手术方法。     

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.

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.
