The relational underpinnings of quality internal auditing in medical clinics in Israel

Internal auditing is a key mechanism in enhancing organizational reliability. However, research on the ways quality internal auditing is enabled through learning, deterrence, motivation and process improvement is scant. In particular, the relational underpinnings of internal auditing have been understudied. This study attempts to address this need by examining how organizational trust, perceived organizational support and psychological safety enable internal auditing. Data collected from employees in medical clinics of one of the largest healthcare organizations in Israel at two points in time six months apart. Our results show that organizational trust and perceived organizational support are positively related to psychological safety (measured at time 1), which, in turn, is associated with internal auditing (measured at time 2).     

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     

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。

目的研究大剂量生脉注射液对慢性心功能衰竭（简称心衰）患者凝血功能的影响。方法将60例慢性心衰患者随机分为治疗组（即生脉注射液组）和对照组，每组各30例，治疗组给予生脉注射液加西药常规治疗，对照组仅西药常规治疗，观察用药前后心功能改善程度及血浆P-选择素、血管性血友病因子（vWF）和D-二聚体水平的变化。结果治疗组临床显效率与总有效率明显高于对照组。心是患者血浆P-选择素、vWF和D-二聚体水平明显高于健康人，治疗后两组患者血浆P-选择素、vWF和D-二聚体水平均下降，治疗组优于对照组。结论慢性心衰患者，体内存在着高凝状态，大剂量生脉注射液可改善慢性心衰患者的凝血功能，可能在一定程度上减少心衰患者血栓事件的发生和发展？     

Safety, tolerability and pharmacokinetic study of recombinant human parathyroid hormone in healthy male Chinese subjects

AIM： To determine the safety, tolerability and pharmacokinetic parameters of a new drug recombinant human parathyroid hormone [ rhPTH （1-84）] in healthy male Chinese subjects. METHODS： domly divided Thirty-six healthy male volunteers were rangroups received into 3 groups. The volunteers in these single subcutaneous injection of rhPTH （ 1-84） in a dosage of 1, 2 and 4 μg/kg respectively. Blood samples were obtained before and after administration within 24 hours. The rhPTH concentrations in sennn were determined by enzyme linked immunosorbent assay （ELISA）. The pharmacokinetic parameters determined with use of standard noncompartmental analysis were the maximum serum concentration （ Cmax ）, the time to attain that concentration （ tmax ）, and the area under the serum concentration-time curve up to 24 hours（ AUC0-24 ） and up to infinity （AUC0-∞）. Dose proportionality of pharmacokinetic parameters （AUC, Cmax of every volunteer of each dosage and A UC was computed from log transformed data） and was examined by mean of analysis of variance （ANOVA） using SPSS software package. In the study, subjects＇ symptoms, objective signs, and vital signs, including blood pressure, heart rate, respiratory rate and body temperature, were checked and 12-lead electrocardiography was recorded before and after drug administration within 24 hours. Routine laboratory tests, including hematology, blood biochemistry, serum electrolyte, and urinalysis, were performed before and after drug administration within at 24 hours.[第一段]
