Association Between Patient and Physician Sex and Physician-Estimated Stroke and Bleeding Risks in Atrial Fibrillation

Background

Physicians treating nonvalvular atrial fibrillation (AF) assess stroke and bleeding risks when deciding on anticoagulation. The agreement between empirical and physician-estimated risks is unclear. Furthermore, the association between patient and physician sex and anticoagulation decision-making is uncertain.

H型高血压患者舌面诊图像颜色特征参数分析＊

目的 分析H型高血压患者的舌面诊图像颜色参数特征，探讨H型高血压患者的舌诊、面诊变化规律。方法 运用上海中医药大学自行研制的Smart TCM-1型中医舌面一体仪，采集高血压患者舌面诊图像，提取特征参数，分析健康对照组、H型高血压组与非H型高血压组患者舌面颜色参数特征。结果 ①在舌色各项参数中，H型高血压组舌尖部R值、B值、V值均显著小于健康对照组（P < 0.01）；非H型高血压组舌尖部B值显著小于健康对照组（P < 0.01），S值较健康对照组显著增大（P < 0.05）；H型高血压组舌尖部R、V值均明显小于非H型高血压组（P < 0.05）。在舌苔各项参数中，H型高血压组舌中H值、V值均明显小于健康对照组（P < 0.05）；非H型高血压组舌中V值、舌右V值均显著小于健康对照组（P < 0.01）；H型高血压组舌中H值明显小于非H型高血压组（P < 0.05），右侧舌苔S值明显大于非H型高血压组（P < 0.05）。②H型高血压组面色参数鼻G值、下颌G值、口唇R值、口唇V值均明显小于健康对照组（P < 0.05）；非H型高血压组前额H值、目眶H值、脸颊H值、鼻H值、下颌H值、整体H值均明显大于健康对照组（P < 0.05）；H型高血压组前额H值、目眶G值、目眶H值、脸颊H值、鼻G值、鼻H值、下颌R值、下颌G值、下颌H值、下颌V值、口唇R值、口唇G值、口唇V值、整体R值、整体G值、整体H值、整体V值均明显小于非H型高血压组（P < 0.05）。结论 H型高血压患者苔色偏黄，以舌中部为主，且舌右侧黄苔积聚较明显；H型高血压患者面色为黄中带红，口唇、下颌部更为晦暗。H型高血压患者的舌、面诊特征参数的变化，与高血压病阳亢湿盛病机相符。     

Outcomes of Early Decompressive Craniectomy Versus Conventional Medical Management After Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis

This meta-analysis examined whether early decompressive craniectomy (DC) can improve control of intracranial pressure (ICP) and mortality in patients with traumatic brain injury (TBI).Medline, Cochrane, EMBASE, and Google Scholar databases were searched until May 14, 2015, using the following terms: traumatic brain injury, refractory intracranial hypertension, high intracranial pressure, craniectomy, standard care, and medical management. Randomized controlled trials in which patients with TBI received DC and non-DC medical treatments were included.Of the 84 articles identified, 8 studies were selected for review, with 3 randomized controlled trials s having a total of 256 patients (123 DCs, 133 non-DCs) included in the meta-analysis. Patients receiving DC had a significantly greater reduction of ICP and shorter hospital stay. They also seemed to have lower odds of death than patients receiving only medical management, but the P value did not reach significance (pooled odds ratio 0.531, 95% confidence interval 0.209–1.350, Z = 1.95, P = 0.183) with respect to the effect on overall mortality; a separate analysis of 3 retrospective studies yielded a similar result.Whereas DC might effectively reduce ICP and shorten hospital stay in patients with TBI, its effect in decreasing mortality has not reached statistical significance.     

尘肺病患者心理、社会支持状况调查及相关性研究

目的为了解尘肺病患者心理状况及社会支持对患者心理健康的影响,为对尘肺病患者建立干预措施提供技术支撑。方法采用SCL-90症状清单、社会支持量表对在全省尘肺病住院病人较多的3家医院进行尘肺病患者问卷调查。结果 208名尘肺病患者男性205人,女性3人。文化程度均为高中及以下;Ⅰ期尘肺148人,Ⅱ期尘肺41人,Ⅲ期尘肺19人;尘肺患者SCL-90症状清单总分为162.00±64.77,低于全国常模,差异有统计学意义(P0.05);不同分期、不同年齡段、不同病程尘肺病患者各组之间社会支持得分差异无统计学意义。结论尘肺病患者心理健康水平低于全国水平,社会支持各维度得分与SCL-90各因子得分呈负相关,建立尘肺病患者心理干预体系十分必要。     

一腓骨肌萎缩症家系临床及基因分析

目的分析一腓骨肌萎缩症家系的临床表现及不同基因检测方法的特点。方法收集一CMT家系8名成员临床资料,并应用等位基因特异性PCR-双酶切方法及多重连接依赖的探针扩增技术(MLPA)检测PMP22基因突变情况,同时选择60名性别、年龄无明显差异的健康人做为对照组。结果该家系中患病者以行走不稳、跨阈步态,伴有弓形足为主要临床表现。该家系中5名成员经等位基因特异性PCR-双酶切及MLPA方法均检测出PMP22基因重复序列,其中出现临床症状的有4名(Ⅱ3、Ⅱ9、Ⅱ11、Ⅲ7),未出现临床症状但基因检测结果示PMP22基因重复序列的为携带者有1名(Ⅲ5),家系中余3名成员及对照组60名均未见重复序列。结论基因检测在明确CMT诊断中起重要作用,且MLPA法筛查基因时操作更简便、灵敏度更高、特异性更好。

Correction of frequency and phase variations induced by eddy currents in localized spectroscopy with multiple echo times.

As a consequence of the time-varying magnetic field induced by eddy currents, frequency drifting occurs when the sampling window of localized spectroscopy continuously shifts. The frequency drifting and the concomitant phase variations can severely affect spectroscopy results when data are acquired with multiple echo times (TEs), such as in the measurement of glutamate (Glu) concentration using the TE-averaged method. Specifically, the averaged spectra are further broadened and distorted in the presence of residual eddy currents, and editing of the coupled spins of Glu C4 protons is affected, resulting in errors in the measured relative intensity ratio. Postacquisition correction using unsuppressed water as reference can effectively minimize this detrimental effect, as manifested by the significantly enhanced signal intensity. Also, it is demonstrated that the methyl signals of creatine (Cr) at 3.0 ppm and choline (Cho) at 3.2 ppm can be used as internal references in finding frequency and phase disparities between different TEs.     

足部骨筋膜室综合征早期诊断与治疗

目的:探讨足部骨筋膜室综合征早期诊断与治疗结果。方法:1998年1月-2003年12月收治15例足骨筋膜室综合征患者(均为男性:年龄15～55岁,平均32岁),行足背双切口减压4例,足底内侧减压9例,足内外两侧减压2例。1周后行减张缝合或植皮术。结果:15例随访9～24个月,12例恢复佳,足运动感觉正常;2例有足底感觉减退、足趾麻木;1例遗留前足挛缩、无力,足趾麻木。无爪形趾及功能障碍者。结论:足损伤后,Whiteside法测定组织间隙压力是诊断足骨筋膜室综合征的可靠方法。治疗时足部如有骨折、血肿者,骨筋膜室减张切口,宜选择足底内侧切开效果较好。
