Leukemia is a critical disease with a high incidence and extremely high fatality rate.Immune escape by leukemia stem cells(LSC)is the main factor for recurrence and progression after remission.Clinical diagnosis and treatment by Traditional Chinese Medicine(TCM)have distinct advantages of syndrome differentiation and treatment.Based on the purpose of diagnosis and treatment,leukemia treatment by TCM emphasizes the harmony of yin and yang to restore human functions,which is conducive to improve autoimmunity and conforms to the mechanism of intervention for tumor cell immune escape.This article discusses the mechanism and research progress of TCM interventions in LSC immune escape based on literature and TCM theory.

Objective To construct a rating scale on the knowledge,attitude,and practice of geriatrics for 8-year clinical medical students and undergraduate nursing students,and to test the reliability and validity of the scale.Methods The Knowledge,Attitude,Practice(KAP)theory was used as a guided framework,relative literatures were reviewed,and topics for question answering were discussed by experts group.Then,a questionnaire was initially constructed.Five methods,including discrete trend method,Cronbach coefficient,t-test,correlation analysis,and factor analysis,were used to screen the attitude and practice items.The knowledge items were evaluated by experts.Items with over three exclusion criteria were deleted when combining the literal questions.The construct validity of the integrated scale was assessed by factor analysis.A pilot research was conducted by 100 eight-year medical students and nursing undergraduates selecting question entries,and the reliability and validity of the scale were examined.Results The scale consisted of three dimensions.A 43-item initiate questionnaire on the scale included 13 items for knowledge,11 for attitude,and 19 for practice.Two knowledge items were deleted according to expert evaluation.Seven items with more than three exclusion criteria were deleted after statistical analyses.Eventually,34 items were included in the questionnaire.The Cronbach α coefficient of the questionnaire was 0.702.And three common factors were extracted according to exploratory factor analysis.Conclusions The reliability and validity of Geriatrics Knowledge,Attitude and Practice scale for eight year medical students and nursing undergraduates are acceptable,but the knowledge items should be recomposed.

Spinocerebellar ataxia (SCA) is a group of highly heterogeneous autosomal dominant genetic disease, including many subtypes. SCA11 is a rare subtype of SCA, and is caused by mutant TTBK2 gene. A case of SCA11 was reported in this article. Whole exome sequencing showed that there was a c.1284dupA frameshift mutation in TTBK2 gene. Literature review found that only 6 pedigrees of SCA11 have been reported, but the mutation site of this case is a novel identified mutation that has not been reported in the Human Gene Mutation Database.

Objective:To explore the application of the 4R problem analysis method combined with reverse teaching in nursing teaching in the pediatric operating room.Methods:In this study, 480 nursing students who were assigned to the operating room of Hunan Children's Hospital for internship from August 2020 to August 2022 were selected as research subjects. They were divided into control group and observation group in order of admission, with 240 students in each group. The control group received traditional teaching, while the observation group received the 4R problem analysis method combined with reverse teaching. At the end of the internship, the two groups were compared for comprehensive ability assessment scores, recognition of nursing teaching, and degree of satisfaction with the teaching. The t-test and χ2 test were performed using SPSS 22.0. Results:The scores of theoretical knowledge, basic nursing skills, specialized nursing skills in the operating room, and comprehensive nursing skill assessment of the observation group were significantly higher than those of the control group ( P<0.05). The recognition of nursing teaching among the nursing interns in the observation group was significantly higher than that in the control group ( P<0.001). There was a significant difference in the degree of satisfaction with the teaching between the two groups of nursing interns ( χ2=118.35, P<0.001). Conclusions:The 4R problem analysis method combined with reverse teaching can effectively improve the nursing teaching quality and the degree of satisfaction with the teaching among nursing interns in the pediatric operating room, enabling them to better grasp theoretical and practical skills.

OBJECTIVETo analyze the biochemical and pathological changes in mice with type 2 diabetes mellitus (T2DM) induced by high-fat diet combined with low-dose streptozotocin (STZ) injections.

METHODSC57BL/6J mice were divided randomly into normal control group (NC group), high-fat diet group (HC group) and high-fat diet plus STZ group (HC+STZ group). The mice were fed on normal chow or a high-fat diet for 1 month before two introperitoneal injections of STZ (40 mg/kg) or citrate buffer with an interval of 24 h as appropriate. Fasting blood glucose (FBG) was detected every week for 4 weeks, and oral glucose tolerance test (OGTT) was performed one month after the injections, after which the biochemical profiles, islet and liver were evaluated by immunohistochemical and pathological analysis.

RESULTSIn HC+STZ group, FBG was above the cutoff value (13.89 mmol/L) in 75% of the mice at 1 week after STZ injections and in all the mice at two weeks except for the death of 1 mouse, with a success rate of modeling of 91.3%. FBG in HC group, though slightly higher than that in NC group, remained normal (6.8 mmol/L). The body weight in HC+STZ and HC groups was significantly higher than that in NC group after feeding but without obvious increases after the injections (P<0.01). Blood glucose in HC+STZ group at 0.5 to 2 h after OGTT and the area under curve (AUC) were higher than those in NC and HC groups (P<0.01); the AUC in HC group was a also higher than that in NC group (P<0.05). Plasma creatinine was significantly higher in HC+STZ group than in NC (P<0.01) and HC (P<0.05) groups. Insulin secretion by the islets decreased obviously in HC+STZ and HC group. The mice in HC+STZ group showed atrophy, fibrosis, and vacuolization in the islets with mild fatty liver but no visible renal pathologies.

CONCLUSIONHigh-fat diet and low-dose STZ injections can induce T2DM in mice with very similar biochemical and pathological changes to human T2DM and with such complications as fatty liver.

Although primary vesical calculi is an ancient disease, the mechanism of calculi formation remains unclear. In this study, we established a novel primary vesical calculi model with d,l-choline tartrate in mice. Compared with commonly used melamine and ethylene glycol models, our model was the only approach that induced vesical calculi without causing kidney injury. Previous studies suggest that proteins in the daily diet are the main contributors to the prevention of vesical calculi, yet the effect of fat is overlooked. To assay the relationship of dietary fat with the formation of primary vesical calculi, d,l-choline tartrate-treated mice were fed a high-fat, low-fat, or normal-fat diet. Genetic changes in the mouse bladder were detected with transcriptome analysis. A high-fat diet remarkably reduced the morbidity of primary vesical calculi. Higher fatty acid levels in serum and urine were observed in the high-fat diet group, and more intact epithelia in bladder were observed in the same group compared with the normal- and low-fat diet groups, suggesting the protective effect of fatty acids on bladder epithelia to maintain its normal histological structure. Transcriptome analysis revealed that the macrophage differentiation-related gene C-X-C motif chemokine ligand 14 (Cxcl14) was upregulated in the bladders of high-fat diet-fed mice compared with those of normal- or low-fat diet-fed mice, which was consistent with histological observations. The expression of CXCL14 significantly increased in the bladder in the high-fat diet group. CXCL14 enhanced the recruitment of macrophages to the crystal nucleus and induced the transformation of M2 macrophages, which led to phagocytosis of budding crystals and prevented accumulation of calculi. In human bladder epithelia (HCV-29) cells, high fatty acid supplementation significantly increased the expression of CXCL14. Dietary fat is essential for the maintenance of physiological functions of the bladder and for the prevention of primary vesical calculi, which provides new ideas for the reduction of morbidity of primary vesical calculi.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.
