Pancreatic cancer–Palliative therapy: surgery (bypass/resection)

Objective: We compare the outcome of palliative pancreaticoduodenectomy and palliative surgical bypass in patients with advanced pancreatic carcinoma in our hospital. Recent published related articles are also reviewed. Methods: A respective analysis was performed comparing the perioperative parameters and outcome of 20 patients who underwent pancreaticoduodenectomy with a gross suspected cancer residue and 30 patients who underwent a surgical bypass, all of the patients were diagnosed as in advanced stages intra-operatively. Results: The two groups were comparable with patient characteristics, including age, gender, initial symptoms and concomitant major organ diseases. Tumors are similar in size and intra-operatively diagnosed as in advanced stages in both groups. All of the patients in the resection group were microscopically proved having cancer residue. One postoperative mortality occurred in the resection group (5%), zero in the bypass group (P > 0.05). Overall complications were significantly higher in the resection group (30% vs. 0, P < 0.01), including 2 patients developed Acute Respiratory Distress Syndrome (ARDS), zero in the bypass group (P < 0.01); hemorrhage and transfusions in the resection group were much more than that in the bypass group (P < 0.05). Hospital stay after resection was significantly longer than bypass (20 vs. 12 days, P < 0.01). Hospital fee after resection was 4 times more than after bypass (median 61.500 vs. 15. 300 yuan, P < 0.01). Survival was significantly longer after resection (median 12.2 vs. 7.1 months, P < 0.01). Conclusion: Our results show that palliative resection in advanced pancreatic carcinoma lengthens the survival time of the patients, but this is paid for significantly higher complications than bypass.     

可调节型充气体位垫的制作和应用

手术中常用体位垫来调整体位及预防褥疮,但以往使用的软垫、海绵垫等却不可根据手术及术中的要求来调节高度,我科对其进行研究并利用现有材料,将其改进制成可调节型充气体位垫,投入临床试用,效果较好。现介绍如下。1材料与制作取上海百特医疗用品有限公司生产的3L容量的氯化钠溶液软包装袋一个,将其中一个出口封闭,使其不漏气。将一根长30cm~50cm长的橡胶管固定于另一个出口,使其不漏气,并将输血器调节器穿于橡胶管上,调节滚轴,起开关作用。连接气压止血器充气,即成可调节型充气调节体位垫。2使用方法根据手术要求将橡胶管连接于气压止血器…

《素问玄机原病式》学术思想探讨

《素问玄机原病式》一书，发挥《内经》病机学说，弥补了原“病机十九条”过于简略之不足，创造性地继承和发展了《内经》理论，特别是首倡“六气皆从火化”之说；关于“相火”的论述，则为后世相火理论的形成奠定了基础；它还总结了温热病的治疗原则，对后世温病学派的形成产生了重要影响。     

Procyanidins extracted from the lotus seedpod ameliorate scopolamine‐induced memory impairment in mice

The major purpose of this study was to determine the effect of procyanidins extracted from the lotus seedpod (LSPC) on the learning and memory impairments induced by scopolamine (1 mg/kg, i.p.) in mice. The capacities of memory and learning were evaluated by the Morris water maze and the step‐down avoidance test. LSPC (50, 100, 150 mg/kg BW, p.o.) significantly reversed scopolamine‐induced learning and memory impairments in the Morris water maze test, as evaluated by shortened escape latency and swimming distance. In the step‐down avoidance test, LSPC (50, 100, 150 mg/kg BW, p.o.) treatment significantly reduced the number of errors and shortened latency compared with that of scopolamine. In addition, LSPC was also found to inhibit acetyl cholinesterase (AChE) activity. These results of this study suggest that LSPC may play a useful role in the treatment of cognitive impairment caused by AD and aging. Copyright © 2009 John Wiley & Sons, Ltd.

糖尿病患者超声乳化白内障吸除手术的临床观察

目的:探讨糖尿病患者进行超声乳化白内障吸除联合人工晶状体植入手术的临床效果。方法:50例(61只眼)糖尿病患者(设为A组)和同期163例(174只眼)血糖正常患者(设为B组)接受超声乳化白内障吸除联合人工晶状体植入手术。糖尿病患者手术前通过饮食疗法、口服药物或肌注胰岛素治疗,使空腹血糖降到 10mmol/L以下。术后随访 1～28个月(平均 8.6个月),复查视力、裂隙灯及眼底检查。结果:术后矫正视力≥0.5者,A组为77.1%;B组为80.5%。两组经统计学处理差异无显著性(P>0.05)。两组术中出现后囊破裂及术后发生角膜水肿和前房渗出等并发症的差异无显著性(P>0.05 )。结论:糖尿病患者进行超声乳化白内障吸除手术前只要有效控制血糖,其手术效果与对照组患者相同。但术后血糖的控制仍然十分重要。眼科学报2003;19:98-100。
