Pancreas divisum with early pancreatic cancer--presenting as chronic obstructive pancreatitis.

A 61-year-old man experienced four bouts of pancreatitis in 1 year. Detailed history taking and a series of examinations, including sonography, computed tomography scan, and endoscopic retrograde cholangiopancreatography (ERCP), revealed pancreas divisum on the first admission. He was treated conservatively. However, repeated ERCP on the fourth admission, 1 year later, showed a small filling defect in the tail of the pancreatic duct. A distal pancreatectomy was carried out. Pathological studies revealed a small papillary adenocarcinoma (1.5 x 1.0 x 0.5 cm) confined to the pancreatic duct grossly with minimal parenchymal invasion microscopically. He has been free from cancer and pancreatitis for 13 months since the operation.     

急性苯中毒对小鼠末梢血象和骨髓细胞构成的影响

取３２只２～３个月的ＢＡＬＢ／Ｃ小白鼠，随机分为４组，每组８只，第１组为对照组，其余３个组为实验组，实验组小白鼠左腿皮下注射苯０．３ｍｌ（１５ｍｌ／ｋｇ体重）．注射后分别于２４ｈ，４８ｈ，７２ｈ脱颈处死。观察中毒前、后末梢血象、骨髓细胞、骨髓细胞构成的变化。结果表明，苯中毒时骨髓变化先于末梢血象的变化，骨髓的病变为造血细胞变性、坏死，大量毛细血管扩张、充血，骨髓细胞构成降低，而且骨髓细胞构成中细胞成分降低早于外周血粒细胞减少。     

Thrombopoietin in postoperative thrombocytopenia following living donor hepatectomy.

Thrombocytopenia is a frequent finding following living donor hepatectomy. It appears more pronounced in right graft donors than in left graft donors. This study analyzed postoperative thrombocytopenia in 20 living liver donors and examined the change of endogenous thrombopoietin (TPO) in its recovery. Platelet count, TPO level, fibrinogen degradation product (FDP), and D-Dimer were measured before surgery and on postoperative days (PODs) 1, 2, 3, 5, 7, and 14. Concurrently, liver and spleen volumes were calculated by computed tomography. Platelet count on POD 3 was significantly lower in right graft donors than in left graft donors (13.0 +/- 3.7 x 10(4)/microL vs. 16.8 +/- 4.0 x 10(4)/microL, P = 0.039) but recovered by POD 7 in all donors. Postoperative elevations of FDP and D-Dimer were significantly higher in right graft donors than in left graft donors. TPO level rose immediately after surgery, peaked on POD 5 in left graft donors and on POD 7 in right graft donors, and fell nearly to preoperative levels by POD 14. Postoperative TPO level per liver volume was significantly higher in right graft donors than in left graft donors. In conclusion, thrombocytopenia following living donor hepatectomy resolved within the first week regardless of graft type and was mainly associated with increasing consumption of circulating platelets, possibly due to intrahepatic and splenic congestion. With a reduced number of circulating platelets, TPO level rapidly increases. Also, with reduced consumption of platelets related to recovery from surgery, thrombocytopenia should resolve. As a consequence, TPO level would be expected to fall.     

关于老年人植入心脏起搏器术后疗养康复的体会

目的避免或减少老年人植入心脏起搏器术后疗养康复过程中起搏器故障和相关疾病的发生。积极治疗基础疾病,改变其不良症状,并通过心理治疗改善不良心理情绪,使其增强自信,提高生活质量。方法入院后,详细了解安置起搏器的时间、类型及工作情况,全面掌握其身体状况和心理特点,为其制定合理的疗养计划。结果疗养期结束后,疗养员无一例出现起搏器故障和发生相关疾病;基础疾病及不良症状得到进一步控制,心理不良情绪得到进一步控制,基本达到了疗养的目的。结论疗养院医务人员应全面了解起搏器的类型及特性;掌握安置起搏器的适应症和容易出现的病症;掌握此类疗养员的身体情况和心理特点,制定合理的疗养计划并按计划认真予以实施,是保证老年人植入心脏起搏器疗养员能够顺利完成疗养生活的有效措施。     

奎的平与氯氮平治疗精神分裂症对照研究

目的：探讨奎的平、氯氮平对精神分裂症的疗效及副作用。方法：80例患者随机分为两组，分别应用奎的平或氯氮平治疗6周，采用四级临床疗效评定标准、阳性症状与阴性症状量表(PANSS)、副反应量表(TESS)评定疗效及副反应。结果：奎的平组有效率87．5％，氯氮平组有效率82．5％。治疗第一周末，奎的平组PANSS量表总分较治疗前差异有显著性(P＜0．05)。奎的平组副反应低于氯氮平组。结论：奎的平与氯氮平疗效相似，但奎的平起效较快，副反应较轻。
