RESUMEN
ObjectiveTo analyze the application of telerehabilitation in patients with coronary heart disease (CHD) based on the theories and methods of the International Classification of Functioning, Disability and Health (ICF). MethodsLiteratures on the application of telerehabilitation in patients with CHD from databases of PubMed, Web of Science, CNKI, and Wanfang data were retrieved from establishment to May 5th, 2022. Scoping review methods were used to analyze the intervention measures, evaluation methods and indicators, rehabilitation outcomes, and influencing factors on patients with CHD based on ICF. ResultsA total of 4 172 literatures were retrieved, and 15 of them from five countries were enrolled. They were almost published in journals on medical and public health, from 2015 to 2022. The main elements of telerehabilitation included nine items: the establishment of telerehabilitation group, the establishment of personal health profiles, physical activity, exercise monitoring, provision of relevant knowledge, communication and guidance from professionals, provision of psychological support, self-report and supervision and reminder of medical staff. According to the ICF framework, telerehabilitation promoted the function of patients with CHD mainly in body function (including b1 mental functions, b4 function of the cardiovascular, hematological, immunological and respiratory systems, b5 functions of the digestive, metabolic and endocrine systems, and b7 neuromusculoskeletal and movement-related functions) and activity and participation (including d2 general tasks and demands, d4 mobility, d7 interpersonal interactions and relationships, d8 major life areas, and d9 community, social and civic life). The factors affecting the activity and participation of patients with CHD contained environmental factors and personal factors, mainly including e1 products and technology, e3 support and relationships, e4 attitudes, and e5 service, systems and policies. ConclusionThis paper summarized nine items of telerehabilitation for patients with CHD, and analyzed the effects and related influencing factors of telerehabilitation on patients with CHD based on ICF.
RESUMEN
Objective:To investigate the role and mechanism of splenic myeloid-derived suppressor cells (MDSCs) in sepsis-induced adrenal injury (SAI).Methods:Thirty male C57 mice aged 6-8 weeks were randomly divided into normal control group ( n = 5), sham operation group (Sham group, n = 5), sepsis model group [cecal ligation and perforation (CLP) group, n = 10] and sepsis+splenectomy group (CLPS group, n = 10). The sepsis model of mice was reproduced by CLP method. In Sham group, only the cecum was opened and separated, then closed, without CLP. In CLPS group, the spleen was removed before CLP. In normal control group, no challenge was given. After 24 hours, the rats were sacrificed by anesthesia, and peripheral blood, spleen, bone marrow, and bilateral adrenal glands were harvested. The pathological of adrenal gland was assessed by hematoxylin-eosin (HE) staining under optical microscope. The ratio of MDSCs in peripheral blood, spleen and bone marrow was determined by flow cytometry. The expressions of MDSCs surface antigen CD11b, Gr-1 and interleukins (IL-6, IL-1β) mRNA in adrenal tissue were measured by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). Western Blot was used to detect the expressions of mammalian rapamycin target protein (mTOR) pathway related proteins including total mTOR (T-mTOR), phosphorylation of mTOR (p-mTOR) and caspase-3. Results:The adrenal cortex and medulla of the normal control group and Sham group were intact and the structure was clear under optical microscope, while in the CLP group, the adrenal gland showed edema, cortical hemorrhage and cell edema. Compared with the CLP group, the adrenal tissue injury was significantly reduced in the CLPS group. Compared with the normal control group and Sham group, MDSCs ratio in the peripheral blood was significantly increased and significantly reduced in the spleen in the CLP group, but there was no significant difference in bone marrow, the expression levels of CD11b, Gr-1, IL-6, IL-1β mRNA and caspase-3 protein were increased significantly and p-mTOR protein expression was significantly decreased in adrenal tissue, there was no significant difference in the expression of T-mTOR protein. Compared with the CLP group, in the CLPS group, the MDSCs ratio in the peripheral blood was significantly decreased (0.143±0.011 vs. 0.324±0.023, P < 0.01), the expression levels of CD11b, Gr-1, IL-6 , IL-1β mRNA and caspase-3 protein in adrenal gland were significantly decreased [CD11b mRNA (2 -ΔΔCt): 2.90±0.56 vs. 5.74±0.13, Gr-1 mRNA (2 -ΔΔCt): 2.71±0.14 vs. 4.59±0.46, IL-6 mRNA (2 -ΔΔCt): 2.44±0.64 vs. 5.17±1.04, IL-1β mRNA (2 -ΔΔCt): 3.58±0.52 vs. 4.44±0.26, caspase-3 protein (caspase-3/GAPDH): 0.05±0.01 vs. 0.13±0.02, all P < 0.01], the p-mTOR protein expression was significantly increased (p-mTOR/GAPDH: 0.61±0.11 vs. 0.27±0.04, P < 0.01). Conclusions:The spleen is the major source of MDSCs in SAI. Splenectomy can attenuate SAI by reducing mobilization of MDSCs and activating the mTOR signaling pathway.
