目的分析老年患者对中期照护的认知度及急性期后的照护需求,为中期照护的开展提供参考。方法收集全科医学科住院的年龄≥60岁的老年患者,出院当天应用日常生活活动能力量表中的Barthel指数对患者进行综合评估。同时对评估需要中期照护的老年患者发放调查问卷,分析老年患者对中期照护的需求情况及认知度。结果884例老年患者中,无需照护442例(50.00%)、中期照护280例(31.67%)、长期照护162例(18.33%)。中期照护需求比例在70~79岁组中最高,不同年龄层中期照护需求比例比较,差异有统计学意义(χ^(2)=386.81,P<0.05)。老年患者对用药指导、精神心理治疗、营养治疗方面的照护需求较大。71.79%(201/280)的患者对中期照护完全不了解,了解的仅占4.29%(12/280)。结论中期照护需求比例在70~79岁年龄组最高,大多数老年患者对中期照护的了解甚少。因此,在我国建立健全中期照护的模式十分必要。

There is a close relationship between the biological functions of lipids and their structures, and various isomers greatly increases the complexity of lipid structures. The C=C bond location and sn-position are two of the essential attributes that determine the structures of unsaturated lipids. However, simultaneous identification of both attributes remains challenging. Here, we develop a visible-light-activated aziridination reaction system, which enables the dual-resolving of the C=C bond location and sn-position isomerism of in lipids when combines with liquid chromatography-mass spectrometry(LC-MS). Based on the derivatization of C=C bonds with Ph I=NTs, their location in lipids could be easily identified by tandem MS. Especially, the sn-position isomers of unsaturated phosphatidylcholine(PC) can be separated and quantified by LC-MS after the derivatization. By using the proposed method, the significant changes of the sn-position isomers ratios of PC in mouse brain ischemia were revealed. This study offers a powerful tool for deep lipid structural biology.

采用电弧辅助活性AA-TIG焊对2.25Cr1Mo0.25V耐热钢和304不锈钢管进行异种钢材焊接,并对其焊接接头的组织、硬度及力学性能进行分析。结果表明,使用AA-TIG焊能够一次性焊透2.25Cr1Mo0.25V耐热钢和304不锈钢,得到成形良好的焊接接头。焊缝处无裂纹等焊接缺陷,焊缝处各元素在焊缝水平方向分布均匀。在靠近两侧母材的焊缝区,Cr、Fe、Ni元素有一定的梯度,但无明显偏聚。焊接接头两边的母材区硬度值较低,在焊缝区域硬度达到最大,焊缝区域的硬度波动范围在400~489 HV之间,最终拉伸试样都断在304母材上,得到的平均拉伸强度为406 MPa,最大的抗拉强度为542 MPa。
