血液病住院患者衰弱状况调查分析

目的:调查血液病住院患者衰弱状况,为制定血液病患者临床治疗方案提供依据。方法:选取2021年6月—2022年2月中国人民解放军联勤保障部队第967医院血液科收治的血液病患者101例作为研究对象,采用Tilburg衰弱量表(TFI)评估患者衰弱状况,依据TFI评分将患者分为衰弱组与非衰弱组,比较两组血常规结果,统计衰弱组TFI各分数人数以及TFI各条目人数。结果:101例患者TFI≥5分49例,衰弱发生率为48.5%。衰弱组红细胞、血红蛋白水平低于非衰弱组,差异有统计学意义(P<0.05);两组白细胞、血小板水平比较,差异无统计学意义(P>0.05)。衰弱组TFI评分7(5,12)分,7分占比最多(26.5%),≥10分占比较少(10%);衰弱组在躯体维度占比>50.0%的分别为疲劳感(87.8%)、行走困难(71.4%)、握力下降(65.3%)、自评身体健康(63.3%)、视力下降(55.1%);心理维度占比>50.0%分别为记忆力减退(67.3%)、抑郁(51.0%);社会维度占比>50.0%为社会关系(91.8%)。结论:血液病住院患者衰弱发生率较高,衰弱程度处于中等水平,发生可能与贫血有关,临床应重视对血液病患者衰弱的评估,根据患者衰弱时所表现出的特征,采取针对性干预措施。

Asymptotic Behavior of Global Classical Solutions of Quasilinear Non-strictly Hyperbolic Systems with Weakly Linear Degeneracy

In this paper, we study the asymptotic behavior of global classical solutions of the Cauchy problem for general quasilinear hyperbolic systems with constant multiple and weakly linearly degenerate characteristic fields. Based on the existence of global classical solution proved by Zhou Yi et al., we show that, when t tends to infinity, the solution approaches a combination of C^1 travelling wave solutions, provided that the total variation and the L^1 norm of initial data are sufficiently small.
