化瘀解毒汤对脓毒血症APACHEⅡ评分、ISTH DIC评分及外周血树突状细胞表面物质表达水平的影响

目的探讨化瘀解毒汤对脓毒血症患者APACHEⅡ评分、ISTH DIC评分及外周血树突状细胞表面物质表达水平的影响。方法将66例脓毒症患者随机分为对照组和化瘀解毒组,每组33例。对照组给予抗感染、补充血容量、积极治疗原发疾病、吸氧等综合治疗,化瘀解毒组在上述基础上加用化瘀解毒汤治疗,每日1剂,持续治疗2周。检测血清炎症因子[白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、降钙素原(PCT)]水平变化,应用急性生理与慢性健康状况评分Ⅱ(APACHEⅡ)、DIC评分评估脓毒症患者病情严重程度,应用流式细胞仪分析树突状细胞相关表面分子CD80、CD83、CD86表达情况,比较临床疗效。结果与治疗前比较,两组血清IL-6、TNF-α、PCT水平均降低(P<0.01),APACHEⅡ评分、ISTH DIC评分均降低(P<0.01),CD80、CD86水平均降低(P<0.01),CD83水平无差异(P>0.05);与对照组比较,化瘀解毒组血清IL-6、TNF-α、PCT水平均较低(P<0.01),APACHEⅡ评分、ISTH DIC评分均较低(P<0.01),CD80、CD86水平均较低(P<0.01),总有效率较高(P<0.01)。结论化瘀解毒汤辅助治疗脓毒血症疗效显著,可有效降低APACHEⅡ评分、ISTH DIC评分,可能与调节外周血树突状细胞表面物质表达有关。

Multimorbidity and functional impairment–bidirectional interplay,synergistic effects and common pathways

This review discusses the interplay between multimorbidity (i.e. co‐occurrence of more than one chronic health condition in an individual) and functional impairment (i.e. limitations in mobility, strength or cognition that may eventually hamper a person's ability to perform everyday tasks). On the one hand, diseases belonging to common patterns of multimorbidity may interact, curtailing compensatory mechanisms and resulting in physical and cognitive decline. On the other hand, physical and cognitive impairment impact the severity and burden of multimorbidity, contributing to the establishment of a vicious circle. The circle may be further exacerbated by people's reduced ability to cope with treatment and care burden and physicians’ fragmented view of health problems, which cause suboptimal use of health services and reduced quality of life and survival. Thus, the synergistic effects of medical diagnoses and functional status in adults, particularly older adults, emerge as central to assessing their health and care needs. Furthermore, common pathways seem to underlie multimorbidity, functional impairment and their interplay. For example, older age, obesity, involuntary weight loss and sedentarism can accelerate damage accumulation in organs and physiological systems by fostering inflammatory status. Inappropriate use or overuse of specific medications and drug–drug and drug–disease interactions also contribute to the bidirectional association between multimorbidity and functional impairment. Additionally, psychosocial factors such as low socioeconomic status and the direct or indirect effects of negative life events, weak social networks and an external locus of control may underlie the complex interactions between multimorbidity, functional decline and negative outcomes. Identifying modifiable risk factors and pathways common to multimorbidity and functional impairment could aid in the design of interventions to delay, prevent or alleviate age‐related health deterioration; this review provides an overview of knowledge gaps and future directions.

The differential roles of contralesional frontoparietal areas in cortical reorganization after stroke

BackgroundStudies examining the contribution of contralesional brain regions to motor recovery after stroke have revealed conflicting results comprising both supporting and disturbing influences. Especially the relevance of contralesional brain regions beyond primary motor cortex (M1) has rarely been studied, particularly concerning the temporal dynamics post-stroke.MethodsWe, therefore, used online transcranial magnetic stimulation (TMS) interference to longitudinally assess the role of contralesional (right) frontoparietal areas for recovery of hand motor function after left hemispheric stroke: contralesional M1, contralesional dorsal premotor cortex (dPMC), and contralesional anterior intraparietal sulcus (IPS). Fourteen stroke patients and sixteen age-matched healthy subjects performed motor tasks of varying complexity with their (paretic) right hand. Motor performance was quantified using three-dimensional kinematic data. All patients were assessed twice, (i) in the first week, and (ii) after more than three months post-stroke.ResultsWhile we did not observe a significant effect of TMS interference on movement kinematics following the stimulation of contralesional M1 and dPMC in the first week post-stroke, we found improvements of motor performance upon interference with contralesional IPS across motor tasks early after stroke, an effect that persisted into the later phase. By contrast, for dPMC, TMS-induced deterioration of motor performance was only evident three months post-stroke, suggesting that a supportive role of contralesional premotor cortex might evolve with reorganization.ConclusionWe here highlight time-sensitive and region-specific effects of contralesional frontoparietal areas after left hemisphere stroke, which may influence on neuromodulation regimes aiming at supporting recovery of motor function post-stroke.
