We have carried out a prospective randomised, single blind clinical trial to investigate the effect of continuous passive motion on range of knee flexion, lack of extension, pain levels and analgesic use after total knee replacement surgery. 85 subjects were randomly allocated to control or study group. All subjects followed the existing rehabilitation protocol, which permits immediate active range of motion exercises and mobilisation with the study group using continuous passive motion for 1 h, twice a day. Outcome measures employed were range of motion, pain assessed on a visual analogue scale and analgesic use according to the WHO ladder. Blinded evaluation was carried out preoperatively, at time of discharge from hospital, 6 weeks, 6 and 12 months postoperation. No significant difference was observed between groups at all time intervals for each outcome variable using Wilcoxon Rank sum tests. The results substantiate previous findings that short duration continuous passive motion following total knee arthroplasty does not influence outcome of range of motion or reported pain. 相似文献

对血清蛋白白球比值参考范围的修改及其临床应用 总被引:1,自引:0,他引:1
李学军 《实用医药杂志(山东)》2006,23(1):34-35
目的探讨血清蛋白白球比值(A/G)的参考范围和A/G在计算过程中产生的误差对临床应用的影响。方法①选取健康查体人员统计其A/G参考范围;②从理论上分析A/G计算误差的存在。结果①以统计结果的2s置信区间作为A/G的参考范围是1.1~2.2;②A/G计算值的误差会远大于相应总蛋白和白蛋白的测定误差。结论A/G较合适的参考范围为1.1~2.2,并且在临床应用中仍可根据实际情况降低其范围的下限。 相似文献

目的探讨缺氧条件对卵巢癌细胞Caov-3体外黏附和迁移能力的影响。方法在常氧和缺氧条件下培养卵巢癌细胞Caov-3,分别用四甲基偶氮唑蓝(MTT)比色法和细胞迁移试验测定常氧和缺氧条件下培养的Caov-3细胞体外黏附和迁移能力。结果缺氧条件下,Caov-3细胞在Matrigel和纤维连接蛋白Fn基质上黏附数量增加,黏附促进率分别为17.1%和15.2%,与常氧条件下比较有显著性差异(P<0.05)。缺氧条件下,Caov-3细胞在Matrigel基质上迁移距离增大,分别为258.8±19.5μm和331.3±24.4μm,迁移促进率为28.0%,与常氧条件下比较有显著性差异(P<0.05)。结论缺氧环境对卵巢癌细胞Caov-3体外黏附和迁移具有明显的促进作用。 相似文献

Abstract Although respiration in trained canines is well investigated, the process of preparing dogs has not been described in any great detail. Moreover, their daytime patterns of sleep and wakefulness during 1 or 2 h of electroencephalogram (EEG) and electrocardiogram (ECG) recordings are not clear. Therefore, we describe the process of selecting and training dogs, in which we recorded EEG and ECG in the laboratory. First, 14 of 1242 dogs dealt with over a 1 year period were chosen. They were trained for 2 h to lie quietly and to sleep in the laboratory; this training procedure was repeated 152 times. Three dogs were then selected and a permanent tracheostomy was performed in one. Finally, EEG and ECG were recorded with the bipolar fine needle electrodes; respiration was recorded simultaneously through a tube inserted to a tracheostomy in one dog. Wakefulness, slow wave sleep (SWS) and rapid eye movement (REM) sleep (REMS) were identified according to the EEG pattern and on the basis of the behavioral criteria. Recordings were performed 12 or 13 times in each dog. Complete sleep cycles, including wakefulness, SWS and REMS in this sequence, were observed 3.9–4.1 times. The mean duration of SWS was 2.2–4.4 min and that of REMS was 3.5–4.6 min. The REMS latency was 33.9–41.8 min. Fluctuation of heart rate with respiration, termed respiratory sinus arrhythmia, was noted in the ECG. Heart beat increased with inspiration and decreased with expiration. The present study demonstrates how to select and train sleeping dogs and shows their undisturbed daytime sleep and wakefulness patterns. 相似文献

A novel cardiokymograph system is introduced. The new system features a capacitance transducer with increased sensitivity
and can be used in multichannel measurements. The novelty of this technique is the injection of a current into the patient
coupled with the use of a capacitive displacement transducer and the possibility of multichannel monitoring. It provides for
the possibility of removing breath noise when some signal processing technique, such as adaptive filtering, is used. Further
investigation is needed to demonstrate clinical significance and pathologies. 相似文献

Contradictory results have been reported about the inhibitory input to the medial rectus subdivision of the oculomotor nucleus of the cat. In the present ultrastructural study, we quantified the GABAergic and glycinergic terminals in the various subdivisions of the rabbit oculomotor nucleus with the use of post-embedding immunocytochemistry combined with retrograde tracing of horseradish peroxidase. The density of the GABAergic input to the medial rectus subdivision was as substantial as that to the other subdivisions and the postsynaptic distribution of the GABAergic and glycinergic innervation did not differ among the different oculomotor subdivisions. 相似文献
