Acute large bowel obstruction complicating acute pancreatitis

We have reported a rare case of acute large bowel obstruction complicating acute pancreatitis. The diagnosis of pancreatitis is often initially not considered in such patients, and is established only at laparotomy. The splenic flexure is the most common site of large bowel involvement. A proximal defunctioning colostomy is the preferred primary management.     

Flexor tendon injuries in children

Flexor tendon injuries in adults differ from those in children. 38 children (22 male and 16 female) with a mean age of 6.7 years were treated for flexor tendon injuries by primary suture and controlled mobilization between 1985 and 1992. 53 flexor tendons were injured (average 1.5 digits per patient) and the injury most commonly affected the little finger (23 patients). 60% of injuries occurred in zone 2. Using Lister's criteria, 82% achieved excellent or good results. Repair of both FDS and FDP was better than repair of FDP alone, even in zone 2. There were three tendon ruptures(all classified as poor results) and one other poor result occurredin a zone injury with an associated ulnar nerve palsy. The outcome after flexor tendon repair in children is better than in adults in our hands because rapid healing of tendons occurs in children. No child has yet required tenolysis because in children adhesions are more pliable. Both flexor tendons should be repaired irrespective of the zone of injury. A functional hand can be expected after flexor tendon repair in children.     

Tax-exempt challenges continue.

National attention to the tax-exempt status issue is not as acute as it has been in the last few years, but the challenges are continuing in a number of states. Hospital administrators and legal experts in Pennsylvania, the nation's flashpoint state on the issue, discuss what's going on and why.

复方金银花擦剂中没食子酸的含量测定

目的：建立测定复方金银花擦剂中没食子酸的含量测定方法。方法：Novapak C18色谱柱，流动相甲醇冰醋酸-二甲基酰胺-水（2：0．5：20：90），检测波长275nm。结果：该法线性关系良好，相关系数r=0．9996，加样回收率为99．02％，RSD=1．94％。结论：该方法操作简单，分离效果好，可用于复方金银花擦剂的质量控制。     

Administrative ethics in the 1990s: CEOs confront payment, access dilemmas.

The 1990s are presenting new challenges to hospital CEOs. One theme currently emerging is the ethics of resource allocation. As they search for ways to fulfill their community responsibilities under pressures related to reimbursement, technology and community desires, hospitals are finding that they must make some very tough choices in how they allocate resources. Given the opportunity, how would you respond? Compare your response to an ethical scenario with those of three nationally recognized hospital CEOs.     

侧脑室注射东莨菪碱和酚妥拉明对幼兔分辨学习的影响

目的 探讨东莨菪碱和酚妥拉明对幼兔分辨学习的影响。方法 将30只比利时纯种幼兔从生后13日龄随机分为三组：东莨菪碱组、酚妥拉明组和生理盐水对照组，观察不同日龄各组幼兔的分辨学习能力。结果 幼兔分辨学习的正确反应一般始于生后15日龄。侧脑室注射东莨菪碱对16日龄以前幼兔分辨学习无明显影响，对17日龄以后幼兔分辨学习产生明显抑制作用。侧脑室注射酚妥拉明对13—23日龄幼兔分辨学习均有明显抑制作用。结论 幼兔生后发育过程中学习能力的发展具明显的阶段性，其原因可能与神经递质系统的发育成熟有关。     

前列腺素E1对大鼠肝脏缺血再灌注损伤的保护作用

目的 探讨前列腺素E1（PGE1）对肝脏 因再灌注损伤的保护作用。方法 制作常温下大鼠部分肝叶缺血再灌注模型，于缺血前经门静脉给予PGE1，45min后恢复血流灌注，并于1h后取门静脉血测定血清谷草转氨酶（GOT）、谷丙转氨酶（GPT）、乳酸脱氢酶（LDH）、肿瘤坏死因子－α（TNF－α）及内皮素1（ET－1），同时取缺血肝叶行病理组织学检查。结果 缺血再灌注组GOT、GPT、LDH及TNF－α和ET－1均明显高于正常对照组，PGE1组则明显低于缺血再灌注组。PGE1组的肝脏病理组织学改变明显轻于缺血再灌注组，并接近正常对照组。结论 PGE1对肝缺血再灌注具有保护作用。
