在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。     

ISOLATION OF VIRULENT TREPONEMA PALLIDUM FRQM HUMAN AORTA THIRTY-TWO HOURS AFTER DEATH FROM CARDIOVASCULAR SYPHILIS

After a comprehensive rernew of the literature on syphilitic aortitis, Longcope, (1) stated in 1913; ": . . . the presence of spiro: chetes in these lesions, as might be expected, cannot by any means be constantly demonstrated with Levaaiti stain. . . . . . . That these organisms are ''Treponema pallidum seems almost certain thouS:h actual proof of such by culture from the arterial lesions, a most difficult task, or direct inoculation into animals, has not as yet been accomplished."     

Investigation of Direct Causes of Drug Relapse and Abstainers’ Demands in a Compulsive Detoxification Center in Wuhan City of China

Objective To identify the direct causes of drug relapse and abstainers’ demand, and to develop programs for the prevention of drug relapse. Methods Abstainers in a Compulsive Detoxification Center in Wuhan City, capital of Hubei Province were randomly selected. An investigation on the direct causes of drug relapse and abstainers’ demands was conducted with multiple-choice questionnaires and face to face interviews. Data were analyzed with SPSS 12.0. Results The direct causes leading to drug relapse included: temptation to use drug again by themselves or by their drug mates, seeking pleasure and ecstasy from drug use, relatively well off living, mental stress, irritation, demoralization, family conflicts, unemployment, feeling distrusted by the family, lack of care and love from the family, and discrimination by others. abstainers’ demands after detoxification and returning to the society included: care and support from the family, employment assistance, changing living environment, understanding by others, support from the society, and keeping far away from drugs. Conclusions Environmental factors are the direct causes of drug relapse, and negative irritation is its predisposing causes. Leaving former residence, more care and help given by both the family and the society and raising their overall quality of life are the demands of abstainers.     

Influence of Chemical Oxygen Demand Concentrations on Anaerobic Ammonium Oxidation by Granular Sludge From EGSB Reactor

INTRODUCTION The phenomenon of anaerobic ammonium oxidation was originally discovered in a denitrifying fluidized-bed reactor treating effluent from a methanogenic reactor in the 1990s[1]. Anaerobic ammonium oxidation (ANAMMOX) process is a strictly anaerobic denitrification process, in which ANAMMOX autotrophic bacteria directly oxidize ammonium to dinitrogen gas using nitrite as electron acceptor. In recent years, the anammox process has received great attention and lots of researc…     

出血性脑室铸型的疗效分析

目的 探讨出血性脑室铸型的治疗方法与疗效。方法 分析脑室外引流、尿激酶脑室内注入、气管切开、控制血压以及脑积水的处理等多种治疗手段在治疗脑室铸型过程中的作用及其效果。结果 经过综合治疗完全恢复日常生活者10例(28．6％)，部分恢复日常工作或独立进行家庭生活者13例(37．1％)，生活需要照顾或护理者7例(20％)，死亡5例(14．2％)。结论 对于出血性脑室铸型这类重症病人早期及时的脑室外引流是快速而有效的抢救措施，尿激酶脑室内注入对溶解血凝块，疏通脑室系统行之有效。气管切开对降低死亡率至关重要，控制血压是防止再出血的关键。脑积水的处理是康复过程中需要高度重视的环节。     

CT多平面重组显示镫骨的方法及应用价值

目的探讨利用螺旋CT多平面重组(mu ltip lanar reform ation,MPR)技术显示镫骨整体结构的方法和临床价值。方法对50例无耳症状、体征的志愿者行平行枕眶线扫描,应用轴位图像行多方位的MPR。比较轴位MPR、冠状位MPR、矢状位MPR和镫骨斜位MPR显示镫骨整体结构的差异。测量镫骨斜位图像显示层面在轴位定位图像上与矢状面的夹角,在冠状位定位图像上与矢状面的夹角。先天性镫骨异常31例,全部病例经电测听检查均表现有不同程度的传音性耳聋,均行听骨链重建术。结果正常组轴位、冠状位、矢状位均未能显示镫骨弓的整体形态,镫骨斜位MPR图像均直观显示了镫骨弓的整体形态和结构。在轴位定位图像上,镫骨斜位MPR图像显示层面与矢状面的夹角为36°±8°,在冠状位定位图像上与矢状面的夹角为57°±6°。异常组31例,其中一侧小腿缺如3例;镫骨弓不发育3例;镫骨底板增厚与周围骨融合16例;镫骨底板上结构(小头、颈、小腿)完全缺如9例,斜位MPR图像均直观显示其病理改变,轴位、冠状位以及矢状位图像均不能准确显示镫骨发育不良的病理改变。结论镫骨斜位MPR图像,能显示正常镫骨整体结构和镫骨异常改变,对听骨链重建术的术前评价具有重要意义。     

Parkinson''''s Disease and Smoking: An Integral Part of PD''''s Etiological Study

INTRODUCTION Parkinson抯 disease (PD), a debilitating neurodegenerative disorder, is featured with bradykinesia, resting, muscular rigidity, gait disturbances, and postural reflex impairment[1]. PD is rare before age of 50 years, but it increases dramatically with older ages, with peak onset occurring during the age of 70-85 years. In the United States, prevalence of PD in all age groups is approximately 150 per 100 000 and is roughly 30 per 100 000 at age of less than 50 years and 800 …
