经络艾灸防治乳腺癌根治术后患侧上肢水肿的效果评价

目的观察循经艾灸预防乳腺癌患者根治术后上肢水肿的效果。方法采用便利抽样法选取乳腺外科乳腺癌根治术的患者150例,随机分为对照组和观察组,每组75例。对照组行常规护理,观察组在对照组基础上在手术侧上肢循经艾灸。于术前1 d、术后第14天和术后1个月,测量两组患者患侧上肢水肿程度。结果观察组术后患侧上肢水肿发生率低于对照组(P<0.05)。结论术后循经艾灸可有效预防乳腺癌根治术后患侧上肢水肿,提高患者舒适度。     

Imaging Features of Pulmonary Immune-related Adverse Events

Pulmonary immune-related adverse events represent rare but potentially severe side effects of immunotherapies. Diagnosis is often challenging, as symptoms and imaging features are not specific and may mimic other lung diseases, thus potentially delaying appropriate patient management. In this setting, an accurate imaging evaluation is essential for a prompt detection and correct management of these drug-induced lung diseases. The purpose of this article is to review the different types of pulmonary immune-related adverse events, describe their imaging characteristics on both high-resolution computed tomography and positron emission tomography/computed tomography and stress their underlying diagnostic challenge by presenting the mimickers.     

Acute Inflammatory Syndrome Induced by Mycophenolate Mofetil in a Patient Following Kidney Transplantation

Mycophenolate mofetil (MMF) is increasingly used to prevent acute and chronic rejection following kidney transplantation and in autoimmune diseases. Here, we report on a patient after kidney transplantation, who developed an acute inflammatory syndrome characterized by fever and oligoarthritis within 1 week after increasing the MMF dosage. MMF was discontinued resulting in a complete resolution of the syndrome within 48 h. We demonstrated in vitro that the patient's phorbol myristate acetate (PMA-) and formyl Met-Leu-Phe (fMLP-) stimulated polymorphonuclear neutrophils (PMNs) developed increased oxidative burst when incubated with MMF. This report demonstrates that MMF can also induce acute inflammatory syndrome in patients following kidney transplantation and that this syndrome might be due to a paradox, pro-inflammatory reaction of PMNs.

调整给药时间减轻顺铂肾毒性的研究

目的　观察不同给药时间对顺铂肾毒性的影响。　方法　 1 6例癌症患者分为两组各 8例 ,分别在上午 1 0时或下午 8时静滴 6 0mg m2 顺铂 ,3～ 4周后作第 2周期化疗时交换给药时间 ,以尿 β2 微球蛋白浓度作为肾小管功能改变的指标。　结果　治疗前两组的尿 β2 微球蛋白浓度均在 2 0 0 μg L以下。治疗后 ,上午 1 0时给药组的尿β2 微球蛋白浓度在第 1周期为 4 96± 6 6 μg L ,第 2周期为 5 0 4± 74 μg L ,下午 8时给药组分别为 2 77± 4 3μg L(t=3.6 6 ,P <0 .0 1 )和 2 83± 39μg L(t=3.6 3,P <0 .0 1 )。 　结论　不同时间给药对顺铂的肾毒性有显著影响 ,下午 8时给药可明显减轻顺铂的肾毒性。     

大鼠腓总神经“π”式桥接于胫神经后再生神经的电生理溯源

目的 研究大鼠胫神经原位桥接切断的腓总神经，观察腓总神经再生程度、神经纤维的来源等。方法 将断裂的腓总神经近端和远端分别就近与胫神经施行端侧吻合，存活18个月后，电生理检测再生神经纤维的动作电位传导，取腓总神经远段行光镜及电镜观察神经纤维再生数量及状态。结果 远段腓总神经有明显的神经纤维再生，远段腓总神经通过邻近神经的桥接与近段腓总神经之间有动作电位传导。结论 断裂腓总神经“π”式桥接于胫神经，部分再生神经纤维可能来源于原腓总神经近段，部分来自胫神经。     

动脉分支处的红细胞流变学研究与小动脉端侧吻合

为了探讨动脉分支处及小动脉端侧吻合处的血液流动方式，采用微循环电视显微镜成像技术，活体观察大鼠肠系膜微动脉分支区域血液流动方式和红细胞流变行为，研究动脉血流方向的改变对血流方式的影响。实验中观察到，在形态各异的大鼠肠系膜微动脉分支区域血液流态为稳定层流；红细胞通过不规则变形能很好地适应血管腔不同的几何形态，以保持血液流态的稳定。结果表明，微小动脉血流方向的改变未能在分支区域导致湍流发生，小动脉端侧吻合只是人为增加了侧支循环，同样不会导致血流紊乱和增加血栓形成的危险     

Monoamine oxidases and alcoholism. II. Studies in alcoholic families

Thirty-five alcoholic families have been studied to investigate the relationship between DNA markers at the monoamine oxidase (MAO) loci and (1) platelet activity levels and (2) alcoholism. A quantitative linkage analysis failed to reveal any evidence that the variation in activity levels cosegregates with the DNA markers. A sib-pair analysis did not reveal a significant excess of MAO haplotype sharing among alcoholic sibs, although the deviation from random sharing was in the direction consistent with an X-linked component. A reanalysis of platelet MAO activity levels in a subset of these families revealed that the lower levels previously found in alcoholics is more likely due to the differences between males and females. Only among males and only when a “broad” definition of alcoholism is used (and MAO activity levels are transformed to normality) does it appear that alcoholics have depressed activities compared to nonalcoholics. Finally, when the confounding due to gender difference is removed, no differences between type I and type II alcoholics are found in these families. © 1995 Wiley-Liss, Inc.
