目的：探讨艾灸对健康人甲皱微循环及血液流变学的影响。方法：选择健康学员及武警战士各30例，年龄20－22岁，应用江苏协达公司生产的XDM－1型微循环电脑检测仪及北京世帝科学仪器公司生产的LG－R－80血液粘度计，LG－B－190型红细胞变形／聚集测试仪。固定专人操作，分别于艾灸前及艾灸后，测试甲皱微循环及血液流变学各项指标的变化。结果：艾灸八邪及三阴交穴后，甲皱微循环各项指标均有明显变化，经统计学处理，红细胞聚集程度、血流速度、流态积分、管周积分均有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）；血液流变学各项指标亦有明显变化，经统计学处理，全血低切相对粘度、全血低切还原粘度、红细胞刚性指数、红细胞聚集指数及血浆纤维蛋白原都有非常显著性差异（P＜0．01），全血高切相对粘度有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）。结论：艾灸八邪及三阴交穴后可明显改善红细胞聚集程度，降低血液粘度，加快血流速度，降低外周血管阻力。     

Slowly progressive hemiparesis in childhood as a consequence of Rasmussen encephalitis without or with delayed-onset seizures

Five young children developed slowly progressive hemiparesis as the initial manifestation of Rasmussen encephalitis (RE). Three have remained seizure free over an observational period of 1.3–1.9 years. In the remaining two patients, seizures occurred after 0.5 and 0.6 years respectively. We suggest that RE might be presently underdiagnosed and should be suspected in cases of new onset hemiparesis. In this series, three out of five patients showed oligoclonal bands on examination of cerebrospinal fluid (CSF) which represented additional diagnostic hints towards an immune-mediated condition. According to recently published formal diagnostic criteria, evidence of progressive cerebral hemiatrophy or bioptic identification of RE-typical inflammation confirms the diagnosis in such cases. Long-term immunotherapy is recommended in order to prevent further tissue loss and functional decline.     

放射线联合p53基因及内皮抑素治疗小鼠前列腺癌皮下移植瘤

Objective To test the hypothesis that p53 gene therapy combined with endostatin can enhance tumor response to radiation therapy of RM-1 mouse xenograft prostate cancer and to investigate its mechanism. Methods A mouse prostate cancer model was established. Then mice with xenograft tumor were randomly divided into group A (control), B (radiation), C (radiation and rAdp53), D (radiation and rh-endostatin) and E (radiation and rAdp53 and rh-endostatin). On day 1, rAdp53 was injected intra-tumorously with 1 × 1010 vp per animal to group C and E. From day 1 to 14, rh-endostatin was given 15 mg/kg intraperitoneally daily to group D and E. On day 4 single fraction of 15 Gy was given to tumors in groups B, C, D and E. Normal saline was injected intra-tumorously or intraperitoneaUy accordingly as control. No treatment was done to group A. Tumor volume was measured daily. Samples were collected on Days 5, 10 and 15. Ki67, CD31, p53 and VEGF were detected by means of immunohistochemistry. Results (1) Radiation alone, radiation combined with intra-tumorous injection of Adp53 and/or intraperitoneal injection of rh-endostatin resulted in tumor growth arrest of RM-1 cells in vivo (P = 0.000). Radiation combined with both rAdp53 and rh-endostatin was the most effective treatment (P < 0.05). (2) All the four treatment groups had a decreased expression of mutant type P53 (P = 0.000). The expression of Ki67 in groups B and C were equal (P 0.05) and increasing (P = 0.000), respectively. Group D had a up-down-up curve (P < 0.05), but group E had a up-down one. On day 5 the expresion of VEGF in group E was the lowest (P < 0.05). An increased expression of MVD compared with the control was shown, and MVD in groups C, D and E were always higher than that in the control (P < 0.05). Conclusions The limitation of radiotherapy could be overcome by combination with beth p53 gene therapy and endostatin on the growth of mouse prostate cancer cell. Radiation, rAdp53 and endostatin have their own role but they can be interacted with each other.     

女性更年期综合征ST-T改变的临床意义

更年期综合征（Climacteric syndrome）系指由于更年期精神心理、神经内分泌和代谢变化，所引起的各器官系统的症状综合症候群。更年期综合征是人生中年向老年过渡时期的一种生理性反应，但有些人症状明显，尤其是在女性，若未充分认识，常误诊为其它疾病。我院自2002-2005年收治更年期综合征女性患128例，其中63例因心电图出现ST-T改变而被疑为冠心病，予以改善冠脉循环治疗，效果不佳，许多患因此产生不必要的精神负担。为此，我们对女性更年期综合征心电图ST-T改变的临床意义作以分析。     

箍效应在前牙核桩冠修复中的作用
