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。     

肩锁钩板治疗不稳定性锁骨外侧段骨折的临床研究

目的：比较肩锁钩板和传统克氏针内固定治疗不稳定性锁骨外侧段骨折的疗效。方法：54例不稳定性锁骨外侧段骨折的患者接受了手术治疗，内固定分别是锁骨钩板或克氏针，根据国外的锁骨外侧段骨折肩部功能评价标准进行6－12个月的术后随访，随访结果运用统计学方法进行分析处理，结果：克氏针内固定组的手术优良率为77．3％，并发症发生率为27．3％，骨折愈合率为81．8％；锁骨钩板内固定组的手术优良率为100％，并发症发生率为3．1％，骨折愈合率100％。两组数据统计学差异有显著性，结论：在不稳定性锁骨外侧段骨折的手术治疗中，锁骨钩板较传统克氏针内固定有较高的手术优良率和骨折愈合率，且并发症的发生率较低，因此，它是一种疗效满意的内固定方法。     

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。     

Combination therapy: lonidamine, hyperthermia, and chemotherapy against the RIF-1 tumor in vivo.

Lonidamine enhances the cytotoxicity in vitro of several conventional antitumor drugs as well as that of hyperthermia (HT). We have investigated the possibility that such enhancement can also be demonstrated in vivo against the RIF-1 tumor system. Two assays were used to examine antitumor activity: tumor growth delay and clonogenicity of cells obtained from tumors from treated animals. We used drug (and HT) doses that by themselves did not achieve significant cell killing. The drugs whose interaction with lonidamine was tested were: cis-diamminedichloroplatinum (CDDP), mitomycin C (MMC), bleomycin, 5-fluorouracil, and nitrosourea. Of these only CDDP and MMC yielded positive data. Both assays gave essentially the same results, showing that antitumor activity reflected direct cell killing. CDDP and MCC activity was also enhanced by HT. When we combined all three modalities, however, the results of the trimodality therapies were no better than that of individual bimodality treatments. These last results suggest that lonidamine and HT have similar mechanisms, most likely inhibition of repair of DNA damage. Our data do suggest that lonidamine may have a role in multidrug therapies that include either CDDP or MMC as a component of the treatments.     

缺失型DMD／BMD患者PCR快速检测的可行性与意义

应用对应于Ｄｙｓｔｒｏｐｈｉｎ基因缺失热区的二对ＰＣＲ引物和一对内对照无关引物，在同一反应体系中扩增，检测６６例ＤＭＤ／ＢＭＤ患者。发现其中２５例存在１７号或４９号外显子缺失，与同时采用ｃＤＮＡ探针杂交检测出的３５例基因缺失相比．检出率达７１．４％。说明该扩增系统能够作为快速筛查缺失型ＤＭＤ／ＢＭＤ患者的有效手段。这对指导合理选用探针，尤其在产前诊断方面，具有重要意义。     

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.     

山东产四种菟丝子免疫增强作用的比较研究

目的 比较山东产四种菟丝子对小鼠免疫功能、抗疲劳、耐缺氧等方面的作用。方法 选用昆明种小鼠，用山东产四种菟丝子的水、醇提取物灌胃，观察小鼠腹腔巨噬细胞吞噬功能、免疫器官重量的变化、游泳实验和耐缺氧等指标。结果 山东产四种菟丝子均可增加小鼠吞噬百分率，使幼龄小鼠的胸腺和脾脏增重，并可显著延长小鼠的游泳及缺氧存活时间。其中以菟丝子和南方菟丝子的作用较好，水提取物的作用优于醇提取物。结论 山东产四种菟丝子具有增强机体免疫功能、抗疲劳、耐缺氧作用。菟丝子中的多糖是其提高机体免疫力，增强体质的有效物质之一。
