AIm.To provide a "patient-norm.lized" param.ter in the proxim.l forearm. m.THODS Sixty-three cadaveric upper extrem.ties from.thirty-five cadavers were studied. A m.scle splitting approach was utilized to locate the posterior interosseous nerve(PIN) at the point where it em.rges from.beneath the supinator. The supinator was carefully incised to expose the m.dpoint length of the nerve as it passes into the forearm.while preserving the associated fascial connections, thereby preserving the relationship of the nerve with the m.scle. We m.asured the transepicondylar distance(ted), PIN distance in the forearm.s neutral rotation position, pronation position, supination position, and the nerve width. Two individuals perform.d m.asurem.nts using a digital caliper with inter-observer and intraobserver blinding. The results were analyzed with the Wilcoxon-m.nn-Whitney test for paired sam.les. RESULTS In pronation, the PIN was within two confidence intervals of 1.0 ted in 95% of cases(range 0.7-1.3 ted); in neutral, within two confidence intervals of 0.84 ted in 95% of cases(range 0.5-1.1 ted); in supination,within two confidence intervals of 0.72 ted in 95% of cases(range 0.5-0.9 ted). The m.an PIN distance from.the lateral epicondyle was 100% of ted in a pronated forearm. 84% in neutral, and 72% in supination. Predictive accuracy was highest in supination; in all cases the m.jority of specim.ns(90.47%-95.23%) are within 2 cm.of the forearm.position-specific percentage of ted. When com.aring right to left sides for teds with the signed Wilcoxon-m.nn-Whitney test for paired sam.les as well as a significance test(with norm.l distribution), the P-value was 0.0357(significance-0.05) indicating a significant difference between the two *** This "patient norm.lized" param.ter localizes the PIN crossing a line drawn between the lateral epicondyle and the radial styloid. Accurate PIN localization will aid in diagnosis, injections, and surgical approaches.

目的:初步研究细胞膜脂筏在m.3T3成骨细胞TNFR1介导信号转导中的作用。方法:应用m.D(10g/L,60m.n)消耗细胞膜胆固醇,以TNF-α(10μg/L)刺激m.3T3成骨细胞0、5、10、15、30m.n或以TNF-α+CHX(10m./L)处理4h诱导凋亡,以SDS-PAGE/Westernblot法检测IκBα、ph-AKT、ph-ERK、ph-p38及caspase-3活性片段表达水平的变化,分析膜胆固醇在TNFR1介导信号转导中的作用。结果:m.D(10g/L)处理60m.n可将膜胆固醇水平减少至约35%。降低膜胆固醇水平不影响TNFR1介导的IκBα信号,但显著抑制TNFR1介导的AKT磷酸化激活;不影响TNFR1介导的caspase-3活化和细胞凋亡;也不影响TNFR1介导的ERK和p38磷酸化激活。结论:消耗膜胆固醇可破坏脂筏结构,提示成骨细胞膜脂筏在TNFR1介导AKT激活的过程中发挥重要作用,而TNFR1介导的NF-κB和ERK、p38及凋亡信号通路的激活并不依赖脂筏。

通过电阻加热方法实现了加热速度为 1 000—5 000℃/s,由此使铁及低碳钢的再结晶温度由 650℃降为 610℃,这一新型的热处理方法——超快速退火法(Ultra-rapid annealing),可以在不到一秒钟的时间内有效地软化材料,使其具有良好的机械性能,而且再结晶机理也要发生变化。在加热速度 1 000 ℃/s以上,回复效应随加热速率的提高而降低。本文重点研究了脱碳、脱氮钢,用超快速退火处理后,材料的最低硬度一般在 87.2 HV2.5kg。

Several m.them.tical m.dels have been proposed to describe the dynam.cs of irradiated cancer cells and to evaluate the tum.ur control probability (TCP). In this article, we propose a TCP m.del-based statistical test for predicting the outcom. of a radiation treatm.nt. We determ.ne the foresight capability of prostate tum.ur erradication (cure) from.m.nte Carlo sim.lations of the dawson-Hillen TCP m.del. We construct the receiver operating characteristic (ROC) curves of the test from.the probability distributions of the fraction of rem.ining tum.ur cells for sim.lated experim.nts that evolve either to cure or non-cure. Sim.lations show that a sim.lar procedure m.y be applicable to clinical data. Results suggest that the evaluation of tum.ur sizes after the treatm.nt has started m.y be used for short-term.prognosis.

Background In patients who present with clinically isolated syndrom.s suggesti ve of m.ltiple sclerosis, interferon beta 1a is effective in delaying evolution to clinically definite disease and in reducing m.I m.asured disease activity. We aim.d to assess whether this drug can also reduce the rate of brain volum. de crease in such patients enrolled in the ETOm. (early treatm.nt of m.ltiple scler osis) trial. m.thods m.I data for brain volum. m.asurem.nts at baseline, m.nth 1 2, and m.nth 24 were available from.131, 111, and 112 patients assigned treatm.n t (22 μg interferon beta 1a), and 132, 98, and 99 patients assigned placebo re spectively. Norm.lised brain parenchym.l volum. (NBV) at baseline and percentage brain volum. changes (PBVC) were m.asured with a fully autom.ted segm.ntation technique. The prim.ry endpoint was conversion to clinically definite m.ltiple s clerosis due to clinical relapse. Analysis was by intention to treat. Findings 4 1 (31%) of 131 patients on interferon beta 1a and 62 (47%) of 132 on placebo converted to clinically definite m.ltiple sclerosis (odds ratio 0.52 [95%CI 0. 3 1-0.86], p=0.0115). m.an PBVC for patients on placebo was -0.83%during the f i rst year, -0.67%during the second year, and -1.68%during the entire study pe riod. Respective values for treated patients were -0.62%, -0.61%, and -1.18 %. The changes in brain volum. were significant in both groups at all tim.point s. A significant treatm.nt effect was detected for m.nth 24 versus baseline valu es (p=0.0031). The num.er of new T2 lesions form.d during the first year correla ted weakly with PBVC during the second year. Interpretation Early treatm.nt with interferon beta 1a is effective in reducing conversion to clinically definite m.ltiple sclerosis and in slowing progressive loss of brain tissue in patients w ith clinically isolated syndrom.s. The m.dest correlation between newlesion form.ation and brain volum. decrease suggests that inflam.atory and neurodegenerative proce
