我们对发生在急诊科的死亡病例了解多少？

目的：通过尸体解剖检查结果来观测临床死亡诊断与实际死凶之间的差异，本研究中的死亡病例均发生在急诊科并向苏格兰地方检查院上报，随后进行尸检。方法：这是在格拉斯哥某医院急诊科进行的一个为期1年的前瞻性研究，所有入选病例系来院前死亡和在急诊科死亡的患者。由有经验的急诊科医师在场判断死亡原因，然后与尸枪结果确定的真正死因进行对照，比较两者之间的差异。     

Inhibitory effect of glycyrrhiza uralensis fish and chelidonium majus L on gastrocarcinogenesis induced by N-methyl-N′-nitron-N-nitrosoguanidine

In order to investigate the antagonistic effect of Glycyrrhiza Uralensis Fish (GUF) and Chelidonium maJus L (CML) on gastrccarcinogenesis induced by MNNG in Wastar rats, we treated the rats with MNNG alone (group 1) and with MNNG plus GUF and CML (group 2 and 3) respectively. The incidence of infiltrating adenocarcinoma of the glandular stomach and duodenum in group 2 was significantly lower than that in group 1 (26.7% vs. 67.8%). The differentiation and aggressivenees of carcinomas occured in group 2 were much better and mild than those in group 1. Present study also demonstrated that the inhibitory effect of CML on proliferation of human stomach carcinoma cell line MGC-803 was very remarkable; in addition, GUF and CML were able to antagonise the mutagenic activation of MNNG. These results suggest that GUF and CML may be empoyed in prevention of gastric carcinoma.

对１６例垂体腺瘤采用单侧鼻前庭切口经蝶切除，效果满意，既可减少手术创伤，又缩短了手术距离，且避免了美容缺陷，是一种设计巧妙，较为实用的手术方法，尤其适用于生长激素腺瘤。     

羊心淋巴流阻断后血清生化指标的改变

为给临床心脏术后监测心淋巴管损伤程度及可能出现的并发症提供参考指标，以手术方法阻断羊心淋巴流并对其血清相关成份进行了测定。实验发现，实验组术后谷草转氨酶（ＳＧＯＴ）、谷丙转氨酶（ＳＧＰＴ）、碱性磷酸酶（ＡＫＰ）、乳酸脱氢酶（ＬＤＨ）均有不同程度的增高，以ＳＧＯＴ增高最为明显，术前均值为４７．５３Ｕ，术后２天增至１０４．２０Ｕ，高峰出现时间最早，多在术后２４小时。血清离子改变中低钾最为突出，血钾在术后２天明显降低（Ｐ＜０．０１），术后７天逐渐恢复，术后１４天恢复至术前水平。血清蛋白改变以球蛋白降低、白蛋白／球蛋白比值升高为主。提示心淋巴循环郁滞可导致心肌细胞损伤、毛细血管通透性和结构的改变。不同酶活性的变化对郁滞的敏感度存在着差异。
