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.

Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

Objective To investigate the differences and the immunocompatibility of wild-type (WT), four-gene modified (TKO/hCD55) and six-gene modified (TKO/hCD55/hCD46/hTBM) pig erythrocytes with human serum. Methods The blood samples were collected from 20 volunteers with different blood groups. WT, TKO/hCD55, TKO/hCD55/hCD46/hTBM pig erythrocytes, ABO-compatible (ABO-C) and ABO-incompatible (ABO-I) human erythrocytes were exposed to human serum of different blood groups, respectively. The blood agglutination and antigen-antibody binding levels (IgG, IgM) and complement-dependent cytotoxicity were detected. The immunocompatibility of two types of genetically modified pig erythrocytes with human serum was evaluated. Results No significant blood agglutination was observed in the ABO-C group. The blood agglutination levels in the WT and ABO-I groups were higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (all P<0.001). The level of erythrocyte lysis in the WT group was higher than those in the ABO-C, TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups. The level of erythrocyte lysis in the ABO-I group was higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (both P<0.01). The pig erythrocyte binding level with IgM and IgG in the TKO/hCD55 group was lower than those in the WT and ABO-I groups. The pig erythrocyte binding level with IgG and IgM in the TKO/hCD55/hCD46/hTBM group was lower than that in the WT group and pig erythrocyte binding level with IgG was lower than that in the ABO-I group (all P<0.05). Conclusions The immunocompatibility of genetically modified pig erythrocytes is better than that of wild-type pigs and close to that of ABO-C pigs. Humanized pig erythrocytes may be considered as a blood source when blood sources are extremely scarce.

BACKGROUND:The research of dental stem cells in the fields of regenerative medicine and tissue engineering has been deepening,bringing hope for the repair of tooth-related tissues and the treatment of systemic diseases.However,there is a lack of systematic research and analysis on the biological characteristics of dental stem cells in different age groups. OBJECTIVE:To explore the biological characteristics of the human deciduous tooth and permanent tooth pulp stem cells cultured in umbilical cord blood platelet lysate to provide a reliable basis for human platelet lysates to replace fetal bovine serum. METHODS:The pulp tissues of deciduous teeth,juvenile permanent teeth and adult permanent teeth were taken out and cultured in DMEM/F-12 medium supplemented with 10%fetal bovine serum or different concentrations(5%,10%and 15%)of human platelet lysates.Cell proliferation in the four groups was detected by cytometry.The optimal concentration of human platelet lysates was selected for subsequent experiments.Under the optimal concentration of human platelet lysates,human deciduous tooth and juvenile and adult permanent tooth pulp stem cells were cultured in vitro.The cell growth status was observed under the microscope.The specific antigen on the cell surface was detected by flow cytometry.The cell proliferation ability was tested by the cell counting method and CCK-8 assay.The cell differentiation ability in vitro was observed by a three-line differentiation assay. RESULTS AND CONCLUSION:(1)The cell proliferation rate of the 10%human platelet lysate group was the highest.(2)In all three groups,fusiform fibrous cells grew and expanded from around the tissue block.There was no significant difference between deciduous teeth and juvenile permanent tooth cells,but the adult permanent tooth cells were larger than the deciduous and juvenile permanent tooth cells of the same generation.(3)The results of flow cytometry showed that deciduous teeth,juvenile permanent teeth and adult permanent teeth conformed to the phenotypic characteristics of mesenchymal stem cells.(4)The proliferative capacity of adult permanent dental pulp stem cells was significantly lower than those of deciduous teeth and juvenile permanent dental pulp stem cells(P<0.01).(5)mRNA expressions of osteoblast-related genes alkaline phosphatase and bone morphogenetic protein 2,lipoprotein lipase and peroxisome proliferator-activated receptor γ2,mRNA expressions of chondroblast related gene type II collagen α1 and cartilage oligomeric matrix protein in adult pulp stem cells of permanent teeth were significantly lower than those of deciduous teeth and juvenile permanent teeth pulp stem cells(P<0.01).(6)Compared with adult dental pulp stem cells,human deciduous teeth and juvenile permanent teeth dental pulp stem cells have the stronger proliferative capacity and multidirectional differentiation potential,and are more suitable for clinical research and disease treatment.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

Objective To clarify the bottlenecks in the technology transfer work of public hospitals in China,and try to propose work optimization strategies and suggestions from the perspectives of different stakeholders.Methods The relevant literature about the transformation of scientific and technological achievements in public hospitals was searched on CNKI,and inductively summarize the relevant concepts and categories through the three stages of grounded theory coding.Results Through the three stages of coding,85 initial concepts,29 categories,and 5 main categories were sorted out,and a model attributing the influencing factors of the transformation of scientific and technological achievements in public hospitals was constructed,involving five major entities:public hospitals,medi-cal staff,enterprises,government,and universities.Conclusion The work of transforming scientific and technologi-cal achievements in public hospitals involves multiple stakeholders.It can start from the standardized management of public hospitals,the technological breakthroughs of medical staff,the active leadership of the government,the pro-active integration of enterprises,and the talent cultivation of universities to achieve innovation in talent cultivation mechanisms,industry evaluation mechanisms,profit distribution mechanisms,and intelligent management mecha-nisms.

Objective Understanding the cognitive attitude,influencing factors,and demand elements of medical staff in public hospitals towards the transformation of scientific and technological achievements,and proposing coun-termeasures and suggestions to improve the transformation rate of scientific and technological achievements in pub-lic hospitals.Methods Based on a questionnaire survey of the cognition and needs for the transformation of scientific and technological achievements among medical staff in public hospitals,it investigates medical personnel from 12 public hospitals in Anhui Province.Data processing is conducted using descriptive analysis and moderated mediation effect analysis methods.Results The cognitive attitude is positively correlated with influencing factors(r=0.125,P＜0.01),the degree of cognition is positively correlated with demand elements(r=0.599,P＜0.01),and influencing factors are positively correlated with demand elements(r=0.336,P＜0.01).The impact factors of medical staff in the process of scientific and technological achievement transformation play a partial mediating role between cognitive attitude and demand elements,and the technical title of medical staff has a moderating effect.Conclusion There are bottlenecks in the transformation of scientific and technological achievements by medical staff in public hospitals,in-cluding a weak awareness of transformation,limited transformation capabilities,disconnection between scientific re-search achievements and the market,and an unobvious collaborative effect of"government,education,medical care,production,and research".Public hospitals should improve supporting measures in aspects such as talent cultivation,management systems,professional training,and information construction.

Objective:To describe the trend of mortality and death spectrum in Shandong Province from 1970 to 2021 and provide basis for the targeted disease prevention and control.Methods:The data were collected from the death registration reports of Shandong and 3 national retrospective surveys of death causes in Shandong. The change in levels of overall and specific deaths in Shandong in different years were analyzed based on mortality rate, age-standardized mortality rate and constituent ratio of cause of death, differential decomposition was used to quantify the contribution of demographic and non-demographic factors to changes of mortality.Results:The crude mortality rate in residents in Shandong was basically stable from 1970 to 2021, and the mortality rate during 2020-2021 (732.73/100 000) was slightly higher than that during 1970-1974 (671.98/100 000). While the standardized mortality rate decreased significantly, and the mortality during 2020-2021 (183.39/100 000) decreased by 67.71% compared with that during 1970-1974 (568.00/100 000). The negative increase of population factors and the positive decrease of non-population factors reacted each other, so the mortality was relatively stable. Cardiac-cerebrovascular disease was always the leading cause of death, but the constituent ratio of death increased rapidly from 19.70% during 1970-1974 to 54.72% during 2020-2021. The rank in the causes of death changed from the fourth (11.46%) to the second (25.70%) for malignant tumor, from the seventh (5.85%) to the third (5.59%) for injury, from the second (12.87%) to the fourth (4.99%) for chronic respiratory diseases, from the third (12.27%) to the tenth (0.42%) for infectious diseases. The standardized mortality rates of the main causes of death decreased at different degrees, the standardized mortality rates of obstetrical disease, infectious disease, gastrointestinal disease and chronic respiratory disease decreased by more than 50.00%. The age distribution of deaths and the death spectrum in different age groups and in urban-rural populations changed significantly. During 2020-2021, the proportion of deaths in young people aged 0-14 years was 0.54%, which was 97.05% lower than that during 1970-1974, while the proportion of deaths in the elderly aged ≥75 years was 55.14%, which was 55.75% higher than that during 1970-1974. The rank of infectious diseases in the causes of death descended significantly in all age groups, but the ranks of injury, neuropsychiatric disease and malignant tumor rose significantly in adolescents, and the ranks of endocrine nutrition and metabolic disease rose in middle-aged and elderly people. The difference of death spectrum between urban area and rural area became less obvious and the main death causes in urban and rural residents were basically the same during 2020-2021.Conclusions:The death spectrum of residents in Shandong changed significantly. Chronic and non-communicable diseases, especially cardiac-cerebrovascular disease and malignant tumor, should be the focus in disease control and prevention. The prevention and control of diseases in Shandong made remarkable achievement during 1970-2021. However, in the context of population ageing, it is suggested to strengthen the treatment, prevention of diseases and injuries related to the health of the elderly and elderly health care in the future.
