ABSTRACT
Objective:To the molecular mechanism of Yinjiushu in the treatment of non-alcoholic fatty liver disease (NAFLD) by network pharmacology based on the theory of homology of medicine and food; To conduct experimental verification.Methods:The active components and targets of the Yinjiushu were screened through the TCMSP platform. Cytoscape 3.7.2 was used to construct the "Chinese materia medica-component-target" network of Yinjiushu. The potential targets of NAFLD were obtained by using TTD, GeneCards database and DisGeNET database, and the intersection targets of Yinjiushu and NAFLD were obtained by mapping targets with Venn diagram. The high confidence interaction relationship of intersection targets was obtained in STRING database, and the core targets of Yinjiushu in treating NAFLD were screened out. GO function and KEGG pathway enrichment of common targets were analyzed by David database, and the above results were further verified by animal experiments. The rats were divided into blank group, model group, Western medicine group and Yinjiushu high-, medium- and low-dosage groups according to random number table method, with 8 rats in each group. Except the blank group, rats in other groups were fed with high-fat diet to prepare NAFLD model. Each group was given corresponding drugs for intervention. The rats were weighed regularly. The serum contents of GPT, GOT, TC, TG, IL-6, TNF-α, MPO of rats were detected by ELISA. The liver index was calculated. The degree of fatty degeneration of hepatocytes was observed by HE. The expressions of CAT, NOS3, SOD, PI3K, p-Akt, Akt protein were detected by Western blot.Results:A total of 8 418 NAFLD-related targets, 118 kinds of active components from Yinjiushu, and 137 targets acting on NAFLD were screened. The core targets included IL-6, TNF, VEGFA, TP53, JUN, CAT, NOS3, SOD, etc. 20 related signaling pathways were screened from KEGG enrichment pathway, among which PI3K/Akt pathway, calcium ion pathway, cAMP pathway and TNF pathway may play key roles in the treatment. Yinjiushu was closely related to inflammatory reaction, oxidative stress, angiogenesis, autophagy, cell proliferation, differentiation, metabolism, apoptosis, etc., or it could treat NAFLD by promoting cell apoptosis, inhibiting cell proliferation, inhibiting cell migration, etc. The animal experiment proved that Yinjiushu could reduce the body weight, wet liver weight and liver-body ratio of NAFLD rats, reduce some liver function and blood lipid indexes (GPT, GOT, TG, TC), down-regulate serum IL-6, TNF-α and MPO, up-regulate the expression of CAT, NOS3 and SOD in hepatocytes, and activate the expression of PI3K/Akt key protein.Conclusion:Yinjiushu can play a role in treating NAFLD by inhibiting the release of inflammatory mediators, improving lipid metabolism disorder of hepatocytes, repairing oxidative stress injury and promoting the recovery of liver function.

There were 147 patients ifnished hospital visit at 3 months after CIED implantation, the mean time for physician to evaluate data was (14.8±8.4) min; 150 patients ifnished Carelink remote monitor at 3 months after CIED implantation, the mean time for physician to evaluate data was (8.2 ±4.6) min,P<0.0001.Conclusion: Carelink remote monitoring system was easy to use, it may save time in follow-up study which with high satisfaction in clinical practice.
ABSTRACT
Objective To explore the definition, structure, terminology, framework, and models of social support and services, and mea-surement of intellectual disability based ICF approach. Methods The ICF approach and definition and approach proposed by American Asso-ciation on Intellectual and Developmental Disabilities (AAIDD) were adopted. Results The characteristics of intellectual disability are sig-nificant limitations in both intellectual functioning and adaptive behavior as expressed in conceptual, social, and practical adaptive skills, and onset before 18 years old. The framework, domains and contents of services and support for intelligence disability were proposed, as well as the updated measurement of intelligence disability based on new framework and definition. Conclusion The new framework of intel-ligence disability, system of service and support, and measurement are in accordance with the bio-psycho-social model of disability of ICF. The new paradigm will provide framework and tool of measurement, rehabilitation, education, and social services for people with intelli-gence disability.

ABSTRACT
Objective To explore ICF-based measurement and statistical methods, and social support and service systems of intellectual disability. Methods ICF theories and approaches and literature review were applied. Results Based on the theories of function and disability in ICF, intellectual disability was characterized by the impairment of intellectual function and significant limitations in adaptive behavior, and onset before 18 years old. Based on the theories of intellectual disability in ICF, this study rebuilt the framework of intellectual disabili-ty, and modified the measure of intellectual disability by assessing the body function and measuring activities and participation to assess in-tellectual function and adaptive behavior, while analyzing the social support and service systems via environment factors. This study also dis-cussed related problems about the prevalence of intellectual disability. Conclusion New conceptual framework, measurement and statistical method of intellectual disability based on the theories and methods of ICF was discussed and the social support and service systems were in-tegrated into the environmental factor of intellectual disability.
ABSTRACT
Objective To observe the effect of serum containing Dahuang Zhechong Pills on vascular endothelial growth factor ( VEGF) expression in K562 cells of chronic myelogenous leukemia ( CML) and to develop new antiangiogenic drugs for CML treatment. Methods Enzyme-linked immunosorbent assay ( ELISA) was used for the detection of serum VEGF content in 38 CML patients, 11 acute myelogenous leukemia patients and 9 healthy volunteers. SD rats were used for the preparation of serum containing Dahuang Zhechong Pills, and then ELISA was applied for the detection of VEGF content in K562 cells pretreated with serum containing Dahuang Zhechong Pills. Results Compared with the healthy volunteers, myelogenous leukemia patients at chronic phase and acute phase had high serum VEGF content ( P<0.05 or P<0.01) . Compared with blank serum control group, the secretion of VEGF in K562 cells pretreated with serum containing Dahuang Zhechong Pills was decreased obviously ( P<0.01) , and VEGF expression decreased with the increase of drug concentration. Conclusion VEGF content is increased in myelogenous leukemia patients at chronic phase and acute phase, which may be related to the pathogenesis, progress and prognosis of chronic myelogenous leukemia. Serum containing Dahuang Zhechong Pills can inhibit the expression of VEGF in chronic myelogenous leukemia K562 cells and decrease VEGF protein expression in concentration-dependent manner.
