克隆一个您

我的左手因事故彻底毁掉了。本来早已死心塌地准备就这么着终此一生了,可是有一条喜讯传来。据说,有个医治伤残的最新式医院,可以将身体失掉的某一部分修复如初。于是,我便决定试一下。     

Studies in Proprioception（ Part 1 ）

The terms “ proprioceptive deficit“ , “ proprioceptive training“ , and “ proprioceptive rehabilitation“ are being used with increasing frequency in sports medicine literature. Despite the popularity of this terminology, multiple definitions for “ proprioception“ exist. Many researchers have defined proprioception as the afferent input of joint position sense ( i. e. , detection of position or movement } , whereas others consider proprioception in a broader scope of neuromuscular control. In addition to detection of an afferent stimulus, neuromuscular control includes processing of the stimulus and a reactionary efferent output mediated via the neuromuscular system.     

开胸手术患者术前呼吸功能锻炼的指导

目的评估开胸术前呼吸功能锻炼对改善肺功能的效果。方法对58例拟行开胸手术的低肺功能患者,指导进行呼吸、有效咳嗽锻炼,观察锻炼前后患者肺功能改善及动脉血气分析情况。结果锻炼后患者肺活量、潮气量、第1秒用力呼气量、顶峰呼气流速较锻炼前均有不同程度改善（P〈0.05）,锻炼后动脉血氧饱和度、动脉血氧分压较锻炼前明显提高,动脉二氧化碳分压明显下降（P〈0.05）,有显著性差异。结论加强呼吸功能锻炼可改善患者的肺功能,增加手术治疗机会,降低手术风险,提高手术成功率。     

The Inferior Vena Cava Diameter as a Marker of Dry Weight in Chronic Hemodialyzed Patients

We have previously reported that the diameter of the inferior vena cava(IVC) reflects the amount of body fluid in hemodialyzed (HD) patients. The present study was undertaken to depict the criteria of IVC diameters for determining dry weight (DW) in anuric HD patients. In healthy subjects, the maximal diameters during quiet expiration (IVCe) and the minimal diameters during quiet inspiration (IVCi) were (16.7±3.2) and (5.7±5.4)mm,respectively (mean±SD).The collapsibility index (CI,1-IVCi/IVCe), which inversely correlates with the central venous pressure,was 0.68±0.29. In anuric HD patients,the IVCe/CI values before and after HD were 14.9±3.2/0.68±0.24 and 8.2±2.3/0.94±0.09, respectively. IVCe decreased proportionally to the amount of ultrafiltration. In HD patients with hypervolemic pulmonary edema, the IVCe and CI values were 22.4±2.9 and 0.22±0.11, respectively. We proposed that IVCe/CI after HD is (8±3)mm/0.9 ± 0.1 as the markers of DW in anuric HD patients and that an IVCe value≥22mm together with a CI≤0.22 implies the warning level of body fluid retention.
