Experimental study on the immunosuppressive effects of gui zhi tang

In this paper the immunosuppressive effects of Gui Zhi Tang (a famous Chinese medicine) on the murine immune functions are reported. Varying dosages of Gui Zhi Tang administrated orally, i.p. and i.m. were able to inhibit the amounts of PFC, SRFC and the DTH response induced by BSA and the proliferation response of murine spleen cells to Con A and LPS. Further studies showed that Gui Zhi Tang had the inhibitory effect on Interleukin-2 production of murine spleen cells, which might be one of the mechanisms leading to the immunosuppressive effects of Gui Zhi Tang.     

切开复位内固定治疗Gartland Ⅲ型肱骨髁上骨折

目的探讨切开复位内固定治疗Gartland Ⅲ型肱骨髁上骨折的疗效。方法1999年10月-2005年4月，对62例平均年龄7．5岁的患儿，应用切开复位克氏针固定治疗Gartland Ⅲ型肱骨髁上骨折。其中伸直尺偏型41例，伸直桡偏型18例，伸直中间型3例；无伴发血管、神经损伤和筋膜室间隔综合征。闭合性骨折47例，开放性骨折15例。结果术后56例获得随访，随访时间为6～15个月，平均11．5个月。所有骨折均获得愈合。根据Flynn标准进行疗效评价，其中优22例（占39．3％），良21例（37．5％），可9例（16．1％），差4例（7．1％）。伤后8h内手术的优良率为89．7％，伤后8h后手术的优良率为63．0％。直接手术治疗的优良率为90．1％，曾接受手法复位的优良率为67．7％。结论切开复位内固定治疗Gartland Ⅲ型肱骨髁上骨折可取得满意的疗效，是安全、有效的治疗方法。     

Atrophic dermatofibroma accompanied by aneurysmatic characteristics

A 40-year-old man presented a painful haemorrhagic plaque on his chest in the same location where a nodular lesion had been presented for many years. After 2 months, the plaque was replaced by a depressed lesion. The lesion diagnosed as an anetoderma was excised and the biopsy showed an atrophic dermatofibroma accompanied by aneurysmatic characteristics.     

多发性硬化患者血清尿酸水平变化的研究

目的　探讨多发性硬化 (MS)患者血清尿酸 (UA)水平的变化及其临床意义。方法　采用酶定量分析法对 4 3例MS患者和 4 5名正常对照者的血清UA水平进行检测。结果　MS组血清UA水平明显低于对照组 (P <0 0 1)。MS组中病程越长 (P <0 0 1)、神经伤残程度越重 (DSS评分越高 ) (P <0 0 5 ) ,血清UA水平越低 ;女性患者UA水平明显低于男性患者 (P <0 0 0 1) ;经过糖皮质激素治疗后血清UA水平明显回升 (P <0 0 0 1) ,但治疗前血清UA水平越低则疗效越差 (P <0 0 1、P <0 0 5 )。结论　MS患者血清UA水平降低 ,且与MS的病程、伤残程度、疗效及性别密切相关。UA水平升高可能为激素治疗MS的一个作用机制
