病态嗓音的声谱仪分析

无论患有何种喉病,往往会发生呼吸送气异常和声带振动异常,以致喉声源的声学性质由于周期性紊乱和混入噪声等原因而变得不自然,进而引起言语信息传输的障碍。过去耳鼻咽喉科医生一直根据听觉印象和经验,帮助判断疾病的种类和程度,并监视治疗的全过程。多年来,在医学和工程领域,人们还研究用声学分析的方法来客观地评价病态嗓音的声学特征,探讨这些特征在诊断和治疗中所能起的作用。

新生儿吸入性肺炎X线分析

新生儿吸入性肺炎是指新生儿吸入羊水、胎粪或喂养不当吸入乳汁后在肺部发生的炎性反应，是新生儿呼吸系统常见疾病，特别是吸入胎粪后常会引起呼吸窘迫、呼吸衰竭。胸部摄片是诊断本病的重要手段，且对病情程度及预后判断有重要的价值。现将2006年6—12月本院收治的临床X线资料完整的38例新生儿吸入性肺炎的资料回顾性分析如下。

不解剖肝门预结扎病侧肝脏入肝和出肝血管的肝切除术

1952年,ＬｏｒｔａｔＪａｃｏｂ和Ｒｏｂｅｒｔ首先报道在右半肝切除时,通过解剖肝门的方法,预先结扎、切断相应的血管及胆管,以减少断离肝实质过程中肝断面出血。按此方法切肝,称为解剖性肝切除,或称规则性肝切除术。我国学者在20世纪50年代开展肝切除术时,大多采用这种方法。此方法的优点是,由于切肝前预先结扎、切断病侧肝入肝和出肝的血管及胆管,不仅可减少切肝时的出血量,更重要的是它符合肿瘤外科的处理原则,可减少或避免切肝过程中导致癌细胞扩散。缺点是,需要解剖第一和第二肝门,操作复杂、费时而不易掌握、出血较多。因此,自70年代…     

人股动脉血管的径向拉伸性能

OBJECTIVE： To summarize the development of electroacupuncture stimulation in the treatment of stroke-induced limb spasm, to provide research possibilities or clinical development, and to clarify the mechanism and therapeutic effects of electroacupuncture stimulation. DATA SOURCES： Articles relating to therapeutic effects of electroacupuncture stimulation on treatment of stroke-induced limb spasm, as well as clinical studies （which are not limited to age, sex and race）, were retrieved from the China Journal Fulltext Database from January 2000 to December 2007. The key words were stroke, apoplexy, spasm, and electroacupuncture in Chinese. Other articles were obtained from specific journals or books. STUDY SELECTION： Data were first selected by title and abstract. Clinical and rehabilitative studies relating to the effects of electroacupuncture and acupuncture on the treatment of stroke-induced limb spasm were included. Clinical studies related to the rehabilitative treatment of limb spasm were excluded, unless the effects of electroacupuncture stimulation were recorded. DATA EXTRACTION： A total of 338 references were collected; however, 295 of these were excluded. Therefore, 43 articles were analyzed, comprising 40 in Chinese and 3 in English. DATA SYNTHESIS： At present, acupuncture is widely used at home to treat stroke-induced limb spasm; however, acupuncture at different acupoints might cause different clinical effects. Electroacupuncture, which is characterized by analgesia and relief of spasm, can preclude inflammatory edema, improve blood circulation and blood viscosity, inhibit platelet aggregation and adherence, relieve formation of atheromatous plaque in tunica intima of artery, and resist cerebral anoxia, so as to relieve stroke-induced limb spasm. Meanwhile, electroacupuncture combined with rehabilitation can effectively decrease the degree of spasm and improve motor function. CONCLUSION： Acupuncture and moxibustion therapy are superior in the rehabilitative treatment of stroke-induced li
