Objective To screen the key Mutation Genes in endometrial adenocarcinoma and study the relationship between their expression and immune response and prognosis. Methods The data of 543 cases of endometrial adenocarcinoma and 177 cases of normal tissues were downloaded from the Cancer Genome Atlas (TCGA) and genotype tissue expression (GTEX) for bioinformatics analysis. 22 cases of endometrial adenocarcinoma were collected, RT-qPCR was used to verify the gene expression. Results More than 96.38% of the patients had mutations, including missense mutation, single nucleotide mutation and C>T mutation. The top 10 mutations were PTEN, PIK3CA, TTN, ARID1A, TP53, MUC16, PIK3R1, KMT2D, CTCF and CSMD3. In TCGA, the expression of TP53 mutant was significantly higher than that of wild type (P<0.0001). The expression of TP53 in cancer tissue was higher than that in normal tissue, and the expression of TP53 mutant was higher than that of wild type (P<0.05). The overall survival (OS), progression free survival (PFS), disease free survival (DFS) and disease free survival (DSS) of TP53 mutant were lower than those of TP53 wild type (P<0.0001, P<0.0001, P=0.001, P<0.0001). A total of 344 differentially expressed genes (195 up-regulated and 149 down regulated) were identified in wild-type and mutant TP53. Compared with the wild type, the mutant was negatively enriched in the ^“immune effector process^”, ^“immune response^”, ^“immune system progress^”, ^“innate immune response^” and ^“immune response regulation^” pathways (P=0.001). The scores of T cell CD8 +, neutrophil, macrophages and meyloid dendritic cells of TP53 mutant were lower than those of wild type. Conclusion TP53 is highly expressed in endometrioid adenocarcinoma, and the expression of mutant is higher than that of wild type. TP53 mutation is positively correlated with poor prognosis and can inhibit immune response.

Objective To evaluate and analyze the panel composition and conflict of interest management of clinical practice guidelines of rehabilitation.Methods Clinical practice guidelines of rehabilitation were systematically retrieved from PubMed, EMBASE, China Biology Medicine disc, CNKI, Wanfang Data and Medlive database, the National Institute for Health and Care Excellence, National Guideline Clearinghouse, The Scottish Intercollegiate Guidelines Network, World Health Organization (WHO) and Guidelines International Network until January 11, 2020. Two researchers independently screened and cross-checked the literatures, and extracted the basic information of included guidelines, including the title, formulating institution, published journol, as well as the expert group, the number of expert group, the specific division of labor and their discipline, affiliation and the geographic location, the statement and management of conflict of interest, types of conflicts of interest, and whether to accept fund and the source of the fund.Results A total of 84 guidelines were finally included, 17 domestic ones and 67 foreign ones, in which, 52 (61.9%) reported the expert panel; 22 (26.2%) reported the number of expert panel groups, 21 (25.0%) indicated the specific division of work among the members of the expert panel, 74 (88.1%) reported the names of the members of the expert panel, 47 (56.0%) reported the subjects and specialties of the panelists, 70 (83.3%) reported the affiliation and location of panelists, 14 (16.7%) mentioned the management of conflicts of interest, and 25 (29.8%) reported if there were conflicts of interest. Only five of the 16 funded guidelines stated that there was no conflict of interest between the funding and the development of the guidelines. Among them, the reporting rate of expert panel was significantly higher in foreign countries than in China (χ2 = 9.542, P < 0.01), the reporting rate of name of expert panel members and specific division of labor were higher in foreign countries than in China ( χ2 > 4.155, P < 0.05), and the reporting rate of conflict of interest management was also higher in foreign countries than in China ( P < 0.05). There was no significant difference in whether there was a conflict of interest, whether it was funded and the type of funding at home and abroad ( P > 0.05). Conclusion In gerenal, clinical practice guidelines of rehabilitation published at home and abroad are necessary to be improved in the reporting quality of expert group formulation and division of labor, conflict of interest reporting and management. It is proposed that future guideline developers should follow the WHO Handbook for Guideline Development, assign roles of experts, strengthen the management and reporting of conflicts of interest, and standarderize the development process and reporting of the guidelines.

Objective To analyze the contents of the recommendations of stroke clinical rehabilitation guidelines in order to provide advice for the development and implementation of stroke rehabilitation guidelines.Methods PubMed, EMBASE, CNKI, China Biology Medicine disc, Wanfang databases and guideline-related websites were retrieved from the date of establishment to January 2020, to collect stroke clinical rehabilitation guidelines. The main content, recommendations based on evidence, the type of evidences, and the scope of evidence classification had been explored based on World Health Organization Handbook for Guideline Development-2nd Edition.Results A total of twelve guidelines were included in this study, one in Chinese and eleven in English. They were from the United States (3 guidelines), United Kingdom (3 guidelines), Canada (3 guidelines), Australia (2 guidelines) and China (1 guidelines), and published from September, 2005 to February, 2019. Three articles (25.0%) used the Appraisal of Guidelines for Research and Evaluation (AGREE) for quality evaluation, and two articles (16.7%) used Grading of Recommendations Assessment, Development and Evaluation (GRADE) as the grading system. The recommendations covered the areas such as: cognitive dysfunction (4 dimensions) with a recommendation of cognitive function assessment at most (7 guidelines, 66.7%), language and swallowing dysfunction (5 dimensions) with a recommendation of swallowing-related complications at most (10 guidelines, 83.3%), motor dysfunction (6 dimensions) with a recommendation of spasm treatment at most (10 guidelines, 83.3%), and psychological and behavioral dysfunction (4 dimensions) with a recommendation for assessment or monitoring at most (6 guidelines, 50.0%). There were many recommendations in these areas, but the types of evidence were different, and observational studies and/or randomized controlled trials accounted for most.Conclusion There are different types of evidence and levels of recommendation strength. It is proposed for future guideline developers in stroke rehabilitation to follow World Health Organization Handbook for Guideline Development-2nd Edition to improve the quality and the overall implementation of the rehabilitation guidelines, and to improve the quality and safety of rehabilitation.
