足部的110警报系统

多年来,我们在足疗战线上,通过诊病、治病的临床实践,发现不少患者身体不适,在足部都有报警的信号。下面举例如下:病例1:甲状旁腺反射区于某,男,37岁,1999年3月31日来门诊,自述双脚大拇趾后方关节的内侧疼痛难忍,只好利用办公桌的腿挤按疼痛部位,才感到比较舒服。我让其脱掉鞋袜检查,发现疼痛部位正是甲状旁腺反射区,外观颜色红,对疼痛敏

全国卫生工作会议综述

在举国上下认真贯彻党的十四大精神,加快改革,扩大开放的大好形势下,1993年全国卫生工作会议于元月中旬在北京举行。会议的主要议题是学习贯彻党的十四大精神,总结交流卫生改革与发展的经验,进一步解放思想,统一认识,研究部署1993年的卫生工作任务。会议在听取卫生部的工作报告和15个省、市的经验交流之后,主要围绕着解放思想,更新观念,卫生事业发展如何同市场经济相适应,如何用好关于第三产业的有关政策,深化卫生改革如何与落实农村卫生、预防保健结合起来,如何坚持两     

抑郁发作自杀未遂患者脑源性神经营养因子水平及其相关因素研究

Objective To investigate the possible role of brain-derived neurotrophic factor(BDNF)in the pathophysiology of attempted suicide in depressive episode patients.Methods The subjects were 23 depressive episode patients who had recently attempted suicide.24 depressive episode patients without suicide attempt.and 30 sex-age-and education matched healthy controls.The Hamihon Depression Rating Scale-24 items(HAMD24),Beck Helpless Rating Scale(BHS)and Self-rating Idea of Suicide Scale (SIOSS)was used to evaluate the severitv of symptoms.The seruln level of BDNF was detected with sandwich ELISA.Pearson correlation coefficients wag used to measure the correlations between serum BDNF and the related illness variables.Results There were significant difierences in the serum level of BDNF between patients with attempted suicide,pailents without suicide attempt and normal controls(F=21.927,P＜0.05).Post hoc analysis showed the serum BDNF levels in patients with attempted suicide [(57 ±16)ng/L]were lower than that in patients without[(75±28)ns/L;P＜0.05],and were lower in patients without suicide attempt[(75 ±28)ng/L]than that in normal controls[(111 ±39)ng/L;P＜0.01].In patients with attempted suicide,the serum BDNF was negatively correlated to the duration of depressive episode(r=-0.541,P=0.008),the mean BHS score(r=-0.494,P=0.017)and the mean SIOSSscore(r=-0.754.P=0.000).Conclusion The results suggest that the decreased serum brain-derived neurotrophic factor is related to the pathophysiology of attempted suicide in depressive episode patients.     

宫颈癌疫苗试验取得可喜结果

如果人类试验能取得与动物试验相同的好结果,可能在3年内获得一种抗宫颈癌疫苗。英国Glasgow大学研究人员研制出一种增强免疫系统以杀伤癌前期肿瘤的疫苗。在有限的试验中发现,此种疫苗能治愈牛肿瘤,这是类似于妇女患宫颈癌之前的肿瘤。     

1995～2000年参加全国微生物室间质评活动分析

目的 就我室1995－2000年参加全国微生物室间质评活动进行总结分析，以利于进一步提高我室微生物检验的总体水平。方法 对卫生部临检中心发放的质控菌株按其要求进行分离检测，对我室结果进行分析。结果 1995－2000年我室接收质控菌75株，9株菌未转种成功，鉴定正确 61株，误检菌5株。结论 我室对革兰阳性球菌、非发酵菌、革兰阳性杆菌、革兰阴性球菌鉴定正确率较高。但应加强对培养基质量的控制，以提高对荷养菌的分离和鉴定率。     

水泥型羟基磷灰石人工骨的制备及性能分析

Objective: To prepare hydroxyapatite cement (or calcium phosphate cement,CPC) and analyze its capability. Methods: Tetracalcium phospluge (TTCP ) was prepared by the method of high heat. TTCP reacted with in simulated body situation and produced CPC. Its capability was analyzed by scanning electron microscopy ( SEM), X-ray diffraction( XRD). Its density, absorbing water coefficient, macroporosity and compressive strength were measured also. Results: The main element of CPC is hydroxyapatile (HA), its microstructure comprised of petal crys-tals. The diameter of micropore was 4-10μm, density was 1. 922 g/cm^3, macroporosity was 29. 777%, absorbing coefficient was 15. 503%, compressive strength was 42.70 Mpa. Conclusion: This CPC has three-dimensional spatial structure, its strength meets the need of cancellous bone grafting.
