目的分析自发性脊髓出血患者临床症状、影像学及诊治过程,探讨影响其预后的主要因素。方法回顾性分析2015—2023年收治的10例自发性脊髓出血患者的临床资料,并联合应用JOA评分和ASIA损伤分级用于脊髓病变的评估、mRS量表评价患者预后。结果9例患者出现神经根性疼痛,10例均伴不同程度运动、感觉、自主神经受累表现。5例病因考虑为脊髓血管畸形,5例病因不明。3例患者行减压手术治疗,1例术前ASIA分级A级,末次随访仍为A级,另2例ASIA分级由术前B、C级恢复至D级;7例患者内科保守治疗,其中3例入院ASIA分级A级,末次随访1例恢复至D级,另2例仍为A级,其余4例入院ASIA分级B~D级,末次随访2例恢复至E级,2例恢复至D级。JOA评分为轻度、中度及重度残疾的患者恢复率依次72.2%、52.8%、2.9%。结论脊髓血管畸形是脊髓出血最常见病因,CT阴性不能排除脊髓出血,MRI对其诊断价值较高,对有适应证者首选手术治疗,严重神经功能障碍者手术或保守治疗预后均较差,脊髓出血早期JOA评分及mRS评分对其预后评估有指导意义。

米玛斯白鸽与银羽王鸽均属大型肉鸽品种,在我国养殖规模较大.为深入了解二者的生产潜力与差异,本试验随机选取米玛斯与银王鸽种蛋各100枚进行人工孵化,记录蛋形指数,孵化期每日记录蛋质量,每日破蛋观察孵化期胚胎发育情况.乳鸽出壳后将分别交由对应种鸽哺育,记录哺乳期乳鸽体质量和外貌变化.结果显示,米玛斯种蛋的蛋质量、蛋长以及蛋形指数显著大于银王鸽种蛋(P<0.01).孵化期第0~17天米玛斯种蛋与银王鸽种蛋蛋质量均呈现下降趋势.孵化期第0~17天米玛斯与银王鸽胚胎生长发育进程无明显差异,但孵化期第17 d银王鸽胚胎蛋黄吸收程度低于米玛斯胚胎.乳鸽体质量记录结果显示,哺乳期第2天和第5天米玛斯乳鸽体质量显著高于银王鸽乳鸽(P<0.05),但哺乳期第16~20天银王鸽乳鸽体质量却显著高于米玛斯乳鸽(P<0.05).乳鸽外貌观察结果显示,哺乳期第4天银王鸽乳鸽皮肤出现黑色素沉积,与米玛斯乳鸽外观出现明显差异,且哺乳期第14~20天的银王鸽乳鸽羽毛发育和覆盖程度优于米玛斯乳鸽.综上所述,米玛斯与银王鸽的繁殖性能和生长性能各具优势,其中由于米玛斯鸽蛋更大,具有较好的蛋用潜力,而银王鸽乳鸽后期生长速度快,羽毛附着高,更适合用作肉用.此外,可根据生产需求将米玛斯和银王鸽与不同优势品种杂交,培育新型肉鸽品种.该研究为进一步开发米玛斯和银王鸽的生产潜力以及新品种培育提供了基础支撑数据.

The era of open information in healthcare has arrived. E-healthcare supported by big data supports the move toward greater trans-parency in healthcare by making decades of stored health data searchable and usable. This paper gives an overview the e-health-care architecture. We discuss the four layers of the architecture-data collection, data transport, data storage, and data analysis-as well as the challenges of data security, data privacy, real-time delivery, and open standard interface. We discuss the necessity of establishing an impeccably secure access mechanism and of enacting strong laws to protect patient privacy.
