2种清洗设备洗涤医用器械的质量分析

目的通过观察全自动清洗消毒器与超声波清洗机洗涤不同类医用器械的质量,找出不同器械的最佳洗涤方法,为制订各种器械洗涤流程提供依据。方法将回收器械随机分为A洗涤法和B洗涤法。A洗涤法:将回收器械直接放入全自动清洗消毒器内按程序进行清洗、消毒和干燥。B洗涤法:将器械放入超声波机内按程序加酶浸泡、超声波清洗、冷水热水喷淋清洗消毒、上油烘干。比较2种洗涤方法的洗涤效果。结果A洗涤法洗涤后齿类器械剩余残留物为0.52‰,非齿类器械剩余残留物为0.07‰,2种器械洗涤效果差异有统计学意义(!2=28.189,P=0.000),洗涤齿类器械效果差;B洗涤法洗涤齿类器械剩余残留物为0.04‰,非齿类器械剩余残留物为0.01‰,2种器械洗涤效果差异无统计学意义(!2=1.008,P=0.313)。而2组洗涤法洗涤齿类器械效果有统计学意义(!2=44.097,P=0.000);非齿类器械洗涤后剩余残留物对比不明显,洗涤效果差异无统计学意义(!2=2.667,P=0.102)。结论采用超声波清洗机清洗齿类器械洗涤效果佳;而采用全自动清洗消毒器洗涤齿类器械洗涤效果差,但洗涤非齿类器械洗涤容量大,效果好。     

Independent component analysis and clustering improve signal-to-noise ratio for statistical analysis of event-related potentials

OBJECTIVE: To evaluate the effectiveness of a new method of using Independent Component Analysis (ICA) and k-means clustering to increase the signal-to-noise ratio of Event-Related Potential (ERP) measurements while permitting standard statistical comparisons to be made despite the inter-subject variations characteristic of ICA. METHODS: Per-subject ICA results were used to create a channel pool, with unequal weights, that could be applied consistently across subjects. Signals derived from this and other pooling schemes, and from unpooled electrodes, were subjected to identical statistical analysis of the N170 own-face effect in a Joe/No Joe face recognition paradigm wherein participants monitored for a target face (Joe) presented amongst other unfamiliar faces and their own face. Results between the Joe, unfamiliar face and own face conditions were compared using Cohen's d statistic (square root of signal-to-noise ratio) to measure effect size. RESULTS: When the own-face condition was compared to the Joe and unfamiliar-face conditions, the channel map method increased effect size by a factor ranging from 1.2 to 2.2. These results stand in contrast to previous findings, where conventional pooling schemes failed to reveal an N170 effect to the own-face stimulus (Tanaka JW, Curran T, Porterfield A, Collins D. The activation of pre-existing and acquired face representations: the N250 ERP as an index of face familiarity. J Cogn Neurosci 2006;18:1488-97). Consistent with conventional pooling schemes, the channel map approach showed no reliable differences between the Joe and Unfamiliar face conditions, yielding a decrease in effect size ranging from 0.13 to 0.75. CONCLUSIONS: By increasing the signal-to-noise ratio in the measured waveforms, the channel pool method demonstrated an enhanced sensitivity to the neurophysiological response to own-face relative to other faces. SIGNIFICANCE: By overcoming the characteristic inter-subject variations of ICA, this work allows classic ERP analysis methods to exploit the improved signal-to-noise ratio obtainable with ICA.

髋臼骨折的手术治疗

目的：探讨髋臼骨折的手术治疗效果和影响疗效因素。方法：对31例髋臼骨折患进行切开复位由固定治疗。结果：平均随访18个月(6～36月)，根据Matta评分标准优16例，良8例，一般4例，差3例。1例术后发生深部感染，1例术后18个月发生股骨头坏死。结论：髋臼骨折，特别是有移位的髋臼骨折应及时手术治疗。手术医师的经验、骨折类型、手术时机和入路会影响髋臼骨折的疗效。     

Sensitivity of effect variables in rheumatoid arthritis: A meta-analysis of 130 placebo controlled NSAID trials controlled NSAID trials

In a meta-analysis of placebo controlled NSAID trials, the sensitivity of the effect variables was calculated as the correlation coefficient and as the difference between drug and placebo, divided by the placebo group standard deviation. The patient's global evaluation was the most sensitive variable overall. Pain was more sensitive than Ritchie's index. Several variables may be omitted from clinical trials, especially if two active drugs are being compared. For example, the best maximum estimate for the difference in ESR between NSAADs and placebo was 1.0 mm/hr (95% confidence interval −1.5 to 3.4 mm/hr), and for joint size 0.44% (−1.0 to 1.9%), corresponding to a quarter of a millimeter for each of the 10 joints usually measured. It is suggested to record only the patient's global evaluation, pain, and morning stiffness.
