This study demonstrated no statistically significant difference between the treatment groups for pancreatic or peripancreatic infection, mortality, or requirement for surgical interention, and did not support early prophylactic antimicrobial use in patients with seere acute necrotizing pancreatitis.

这项研究表明，在胰腺或胰周炎治疗组死亡率和需要外科手段干预方面没有统计学上显著差异，并且不支持对急性重症出血性胰腺炎患者早期预防性使用抗生素。

It was shown that peroral infection of the larvae with mixture of GP37 and SpltMNPV could not obtained the significant difference from that only with virus. The GP37, however, was fed to the cotton leafworm larvae 30h in advance of virus infection, resulting in around 50% reduction in larvae mortality.

GP37抗体结合实验结果显示，用GP37抗体与病毒粒子结合后感染斜纹夜蛾幼虫，幼虫的死亡率与对照组没有显著差异，证实了GP37蛋白不是存在于病毒粒子外膜上的蛋白或者不是受体结合蛋白。

The method is an effective way to increase the pharmic concentration in the pancreatic blood,and it can also decrease the morbidity and mortality of the patients with acute severe pancreatitis.Thus,this treatment method might be recommendˉed in our clinical practice.

When transgenic rape leaves were fed to Plutella xylostera, mortality of second instar larvae ranged from 33％ to 47％ and the survival larvae had a less weight than the control.

对叶绿体转化植株进行虫试，结果表明，8天后小菜蛾幼虫的死亡率为33％-47％，未死亡的幼虫比对照体重减轻。说明所获得的叶绿体转基因植株具有杀虫和抑制幼虫生长的作用。

objective to explore the related factors of recurrence of chronic subdural hematoma after neurosurgery.methods the related aspects that affected the recurrence in 113 cases with chronic subdural hematomas after neurosurgery were reviewed,and the factors were evaluated by the medical literature.results 5 patients recured after neurosurgery,and 1 patient died.rate of recurrence and death were 4.4% and 0.9% respectively.conclusion age,abnornmal blood coagulation mechanism,density,pneumatosis and drainage volume would affect the prognosis.

目的 探讨影响慢性硬膜下血肿（chronic subdural hematoma，csdh）术后复发的因素。方法回顾2003～2004年本院手术治疗的113例csdh患者，并结合有关文献进行相关分析。结果术后复发5例，死亡1例，复发率和死亡率分别为4.4%和0.9%。复发的5例患者平均年龄69.6岁。其中因服用抗凝剂复发1例，因术后大量颅内积气复发1例，高密度复发1例，等密度到混杂密度复发2例。结论患者的年龄、凝血机制异常、血肿的密度、术后积气和引流量的多少影响csdh患者的预后。
