小切口椎板开窗治疗腰椎间盘突出症32例

目的探讨小切口椎板开窗治疗腰椎间盘突出症(LDH)的疗效。方法将71例单侧、单节段单纯的LDH患者随机分成A、B两组。A组采用小切口椎板开窗,B组采用标准的全椎板切除或扩大椎板切除。所有病例随访1~3年,平均2.5年。结果A组优19例,良5例,中4例,差4例,总有效率87.5%。B组优13例,良9例,中9例,差8例,总有效率79.5%。两组比较差异有显著性(P<0.05)。两组中以腿痛为主要症状接受手术治疗者疗效优于同组中以腰、腿痛为症状者。结论小切口椎板开窗治疗LDH手术创伤小,效果好。     

Impaired Arterial Elasticity Identified by Pulse Waveform Analysis as a Marker for Vascular Wall Damage in Humans With Aging and Hypertension

Advancing age and essential hypertension are themajor risk factors for the pathogenesis of vasculardiseases and lead to changes in vascular structure andfunction [1~3]. Age- and hypertension-related structuraland functional alterations of the arterial wall precedeapparently obstructive atherosclerosis andcardiovascular events. Accumulating evidences indicatethat endothelial function plays a pivotal role in theprotection of vascular structure and function.Endothelial dysfunction is the earliest…
