从环境隐喻的角度看外感病的因机证治＊

外感病是感受六淫、疫毒等外界因素引起的疾病，现代医学认为其主要致病因素为细菌或病毒。在以肉身体验为主要认知手段的古代，中医学家不可能发现细菌或病毒的存在，因而中医学家往往以天人相应的整体观来把握认知外感病。由于外感病的发病与传播受到外界气候环境和社会环境的影响，尤与人体的内环境密切相关。有鉴于此，本文从“环境隐喻”的立场出发，对外感病发病的因机证治进行分析。外界的气候环境和社会环境容易被人们感受，而对于古代无法观察人体的内环境，作者借助《论语·季氏将伐颛臾》中“祸起萧墙”的故事，对人体内环境为何与外感病的发病关系密切作以阐释，并通过人参败毒散、达原饮等方证的案例式说明，揭示清理人体内外环境而达治疗外感病的机理。     

Understanding How Newly Implemented Rehabilitation Best Practices Are Sustained: A Realist Review

ObjectiveWe conducted a realist review to understand how (mechanism) and in what circumstances (context) evidence-based practices are sustained in rehabilitation (outcome).Data SourcesMEDLINE, Embase, reference lists, and targeted websites.Study SelectionTwo independent reviewers calibrated study selection; then 1 reviewer screened all titles and abstracts, while the second reviewer screened a random 20%. We repeated this process for full texts. We included 115 documents representing 61 implementation projects (8.9% of identified documents). Included documents described implementation projects in which physical therapists, occupational therapists, and/or speech-language pathologists were the target users of an evidence-based practice.Data ExtractionTwo reviewers repeated the independent process described in study selection to extract basic study and sustainability characteristics as well as context, mechanism, outcome, and strategy text.Data SynthesisUsing basic numerical analyses, we found that only 54% of evidence-based practices in rehabilitation are sustained. Furthermore, while authors who reported sustainability planning sustained the practice 94% of the time, sustainability planning in rehabilitation is rare (only reported 26% of the time). Extracted text was synthesized using the realist technique of inductive and deductive retroduction in which context, mechanism, outcome, and strategy text are combined into narrative explanations of how sustainability works. To inform these explanations, we applied normalization process theory and the theory of planned behavior. Collectively, the 52 identified narratives provide evidence for 3 patterns: (1) implementation and sustainability phases are interconnected, (2) continued use of the evidence-based practice can be interpreted as the ultimate sustainability outcome, and (3) intermediate sustainability outcomes (ie, fit/alignment, financial support, benefits, expertise) can become contextual features influencing other sustainability outcomes.ConclusionsImplementation teams can use the narrative explanations generated in this review to optimize sustainability planning. This can sustain practice changes and improve quality of care and patient outcomes. Future research should seek to iteratively refine the proposed narrative explanations.     

沙盘游戏疗法在肿瘤放疗患者中的应用

目的探讨沙盘游戏疗法对肿瘤放疗患者心理痛苦及生活质量的作用。方法采用便利抽样法,选取2019年1—12月于上海市质子重离子医院住院进行放疗的49例肿瘤患者为研究对象,采用分层随机分组方法,将患者随机分为对照组28例和试验组21例。对照组给予常规心理护理,试验组在此基础上给予沙盘游戏疗法。采用心理痛苦温度计和欧洲癌症研究与治疗组织生命质量核心量表中的5个功能维度比较两组患者干预前后的心理痛苦程度和生活质量水平。结果干预后,两组患者心理痛苦温度计得分均低于干预前,且试验组得分低于对照组,差异有统计学意义(P<0.01)。干预前后试验组患者的躯体功能、角色功能、认知功能、情绪功能、社会功能维度得分下降程度均小于对照组,差异有统计学意义(P<0.01)。结论沙盘游戏疗法对肿瘤放疗患者的心理痛苦和生活质量有一定改善作用。     

The reliability in determining the deep fascia displacement of the upper trapezius during cervical movement: A pilot study

BackgroundRestricted shoulder fascia displacement may be an etiological factor for myofascial pain syndrome. A diagnostic ultrasound video can follow deep fascia displacement during active cervical movements. Trackers can be applied to videos to convert deep fascia displacement into data points. This study reports on assessors' reliability in evaluating direction and quantifying upper trapezius' deep fascia displacement during active cervical movements.MethodsPT-Sonographer 1 recorded deep fascia displacement of upper trapezius for three sets using HS1 Konica Minolta diagnostic ultrasound. The recording sequence used was cervical flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation. The three assessors used the tracker to determine direction of deep fascia displacement. PT-Sonographer 1 used the tracker three times in quantifying deep fascia displacement. Intraclass correlation coefficient and Kappa determined the assessors' intra-tester and inter-tester reliability.ResultsTen participants were included in the study with a mean±(SD) age of 37±(6). All the assessors had acceptable intra-tester reliability in determining deep fascia displacement on tracker (ICC≥0.40). All assessors had clinically unacceptable inter-tester reliability in determining deep fascia displacement when tracking right rotation (ICC < 0.40). PT-Sonographer 1 had clinically unacceptable intra-tester reliability in determining deep fascia displacement when tracking left rotation (ICC<0.40).ConclusionWe report clinically acceptable assessors' reliability in determining direction and total deep fascia displacement when tracking diagnostic ultrasound videos of cervical flexion, extension, and lateral flexion. Checking for reliable deep fascia displacements may distinguish MPS from non-MPS individuals increasing the utility of diagnostic ultrasound machine and tracker in clinical practice.     

Renal Neoplasia in Tuberous Sclerosis: A Study of 41 Patients

ObjectiveTo study the clinical features and identify unique renal neoplasia subtypes and their prognostic implications in individuals with tuberous sclerosis complex (TSC).Patients and MethodsThe Mayo Clinic nephrectomy registry included 37 patients with TSC diagnosed between 1970 and 2018. Four additional patients were identified from the pathology consultation and autopsy files. All available renal tumors were further characterized using immunohistochemistry and fluorescence in situ hybridization. Clinicopathologic features and follow-up were obtained from the medical record. The American Association for Cancer Research Project GENIE registry was accessed using cBioPortal for molecular profiling of angiomyolipoma (AML).ResultsA total of 276 renal tumors from 41 patients were analyzed. Renal tumors were classified into 9 distinct morphological subtypes, with AML predominating (238 [86%]). Interestingly, all these tumors acted in a benign fashion except one renal cell carcinoma with clear cells and fibromyomatous stroma and one epithelioid AML that metastasized. Molecular profiling studies revealed that epithelioid AMLs were enriched for alterations of TP53, RB1, and ATRX. Eight patients died of direct complications of TSC, including 3 of end-stage renal disease. To date, none have died of a renal epithelial neoplasm.ConclusionThe identification of unique renal neoplasia subtypes may provide important clues to establish a diagnosis of TSC, and in the somatic setting, this finding has important implications for accurate prognostication. These tumors tend to be indolent, and only 2 of 276 tumors in our study exhibited metastatic behavior. Our results support multidisciplinary management with a focus on preservation of renal function.
