原癌基因C－erb B－2蛋白产物在前列腺癌中的表达

应用抗Ｃ－ｅｒｂＢ－２癌蛋白抗体对３０例前列腺癌进行研究，同时选取１０例正常前列腺组织作为对照。结果表明Ｃ－ｅｒｂＢ－２蛋白与肿瘤分化程度有关。并可能对判断其生物学行为，评估预后有重要意义。     

The postoperative recurrence of crohn's disease: An analysis of 37 patients with crohn's disease who underwent endoscopy during initial surgery

A total 37 patients with Crohn's disease who underwent intraoperative endoscopy during resection of the affected intestine were evaluated in this study. The average age of the patients at surgery was 23.2 years. The residual lesions in the remaining intestine identified by intraoperative endoscopy were classified according to their pathologic profiles into three groups: A, B and C. In group A, comprising patients with longitudinal ulcers and/or a cobblestone appearance, 10 of 12 patients had recurrence. In 5 of these 10, the residual lesions were exacerbated and 2 required a further operation. The remaining 5 patients showed recurrence at the site of previous anastomosis and 2 of these 5 required additional surgery.In group B, comprising patients with small ulcers, aphthoid ulcers, or scars, and group C, comprising patients with no residual lesions, recurrence was observed in 13 of 16, and 3 of 9 patients, respectively. The recurrent lesions were all found proximal to, or at the site of previous anastomosis. Additional operations were performed on 3 of the group B patients. The findings of this study revealed that recurrence requiring additional surgery is more frequent at the site of anastomosis, regardless of the endoscopic appearance of the residual lesions.

第一掌背动脉双叶皮瓣在手外科中的应用

我们设计主要以第1掌背动脉为蒂的手背双叶皮瓣,同时修复两个部位的手部皮肤缺损和拇指再造,共10例均获成功。皮瓣面积最小10cm×3cm,最大13cm×5cm,蒂宽1.5cm×2.5cm。皮瓣每叶面积最小为3.5cm×2cm,最大6cm×3cm。文中介绍了本皮瓣的解剖学基础,并对其手术适应证和优缺点进行了讨论。     

一种用于基因表达谱分析的基因芯片方法

目的：通过研究SLE患者外周血基因表达谱的改变，建立一种新型的基因芯片技术用于分子发病机理的研究。方法：提取总RNA，逆转录合成单链cDNA、双链cDNA，体外转录合成生物标记的cRNA与基因芯片进行杂交，通过抗体的检测标记荧光染料Cy3，基因芯片扫描仪进行图像扫描。结果：该方法有较高的重复性和稳定性，SLE患者与正常对照组相比较，鉴定出94个基因存在表达差异。结论：该方法能在较少起始标本量的情况下，有效地进行SLE致病基因的筛选，更好的理解SLE发生的分子机理，并且可在其它疾病研究中推广应用。     

益肾化浊注射液对慢性肾功能衰竭大鼠残余肾中细胞因子含量的影响

通过观察益肾化浊注射液对5／6肾切除大鼠残余肾中细胞因子含量的影响，益肾化浊注射液延缓慢性肾功能衰竭（CRF）模型大鼠肾功能减退的作用机理。结果显示：益肾化浊注射液可以降低5／6肾切在鼠血清肌,尿素氮（P＜0．01），下调肾组织中白细胞介素－1（IL－1）（P＜0．05），白细胞介素－8（IL－8）（P＜0．05）及肿瘤坏死因子（TNF）（P＜0．05）的总体水平，说明益肾化浊注射液可以通过下调5／6肾切除大鼠残余肾中相关细胞因子含量，抑制促炎细胞因子对肾脏的损害，从而延缓CRF的进展。     

恶性肿瘤患者的皮肤转移（附50例报告）

恶性肿瘤的皮肤转移确与患者的病种、病理类型、术前后淋巴结转移情况、临床分期、手术类型、放疗及化疗的剂量、遗传因素有关。其出现于任何部位均提示预后不佳。     

Multiple aneurysms in Beh?et's disease

Beh?et's disease is characterized by recurrent ulcers of the mouth and genitalia and relapsing iritis. It is now recognized as a chronic multisystem disease affecting the skin, mucous membranes, eye, joints, central nervous system, and blood vessels. One of the known vascular complications of Beh?et's disease is aneurysm formation or venous thrombosis. The two patients with Beh?et's disease in this report developed multiple aneurysms over a short time span. Vascular surgeons dealing with young adults with peripheral aneurysms must be aware of this uncommon yet challenging clinical entity.
