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.

Conclusions:Patients with diabetes treated with insulin, with a duration of diabetes ≥10 years and accompanied by UACR ≥30 mg/g are at higher risk of developing DR than those with a single risk factor.

Objective:To investigate the water improvement status and current disease situation in drinking water-borne endemic fluorosis areas of Taiyuan City, evaluate the effect of prevention and control measures, and provide a basis for optimizing control measures.Methods:Monitoring data from 2019 to 2024 for drinking water-borne endemic fluorosis in the diseased areas in Taiyuan City were collected from the Taiyuan Center for Disease Control and Prevention. A retrospective analysis was conducted on water improvement status, water fluoride content, dental fluorosis in children aged 8 - 12, skeletal fluorosis, and urinary fluoride monitoring results in all endemic villages.Results:From 2019 to 2024, all endemic villages in the six endemic counties (districts) of Taiyuan City completed water improvement. The number of water improvement projects each year was 75, 75, 72, 68, 64, and 57, respectively, with all projects operating normally. The qualified rates of water fluoride content each year were 81.33% (61/75), 100% (75/75), 98.61% (71/72), 75.00% (51/68), 87.50% (56/64), and 75.44% (43/57), respectively, with statistical significant differences ( χ2 = 36.99, P < 0.001). The detection rates of dental fluorosis each year were 18.19% (600/3 298), 14.42% (530/3 676), 11.14% (435/3 904), 11.13% (421/3 781), 11.59% (435/3 754), and 5.37% (299/5 567), respectively, with statistical significant differences ( χ2 = 386.42, P < 0.001). In 2024, 824 people were screened for skeletal fluorosis, with 250 cases showing positive symptoms and signs. Among the 250 positive cases, 210 underwent X-ray examination, detecting 170 skeletal fluorosis patients, with an X-ray positive rate of 80.95% (170/210) and a skeletal fluorosis detection rate of 20.63% (170/824). Urinary fluoride monitoring results showed that the geometric mean of urinary fluoride in villages with excessive water fluoride content was 2.95 mg/L, which was higher than the normal upper limit (1.60 mg/L). However, there was no statistically significant difference in urinary fluoride levels between skeletal fluorosis patients and non-skeletal fluorosis individuals ( Z = 0.78, P = 0.434). Conclusions:From 2019 to 2024, the drinking water-borne endemic fluorosis areas in Taiyuan City have undergone comprehensive water improvement and the water improvement projects are operating well. The qualified rate of water fluoride content has fluctuated, while the detection rate of dental fluorosis has decreased. Continuous monitoring is needed in the future to implement long-term water improvement measures and strengthen screening and treatment efforts for patients with fluorosis.

Objective To explore the related factors of postoperative nutritional risk in elderly patients with proximal femoral nail anti rotation(PFNA)internal fixation and establish a prediction model of malnutrition.Methods A total of 574 elderly patients who underwent PFNA internal fixation in the First Medical Center of Chinese PLA General Hospital from January 2021 to June 2024 were included and divided into malnutrition group(n=389)and good nutrition group(n=185).The differences in 39 indicators in aspects of physiological,psychological,social,economic,environmental and medical fields were compared between the 2 groups.Logistic analysis was used to screen the nutritional risk factors,and then a nomogram model was constructed based on these factors.Results Advanced age,lower BMI,higher postoperative Self-Rating Anxiety Scale(SAS)score,less exercise before fracture,being farmers,higher economic pressure,lower preoperative albumin,preprotein and hemoglobin,and lower Barthel index before fracture were independent risk factors for nutritional risk in patients undergoing PFNA internal fixation(P＜0.05).The nomogram prediction model based on the above factors had an AUC value of 0.995(95％CI:0.987～1.000)in predicting the risk of malnutrition in these patients.When the threshold probability＞0.02,this model could be clinically beneficial in predicting the risk of postoperative malnutrition in patients after PFNA internal fixation.Conclusion Our nutritional risk prediction model based on age,BMI,economic pressure,pre-fracture exercise and preoperative albumin and other indicators is constructed for the elderly patients after PFNA internal fixation,and the model has high accuracy and clinical application value.

Objective To construct a standardized training and evaluation index system for professional nurse engaged in lung puncture so as to enrich the training theory system and provide the basis for carrying out relevant work.Methods Using literature analysis method and expert interview way,the first draft of standardized training and evaluation index system for nurses working in lung puncture room was formulated.Two rounds of expert consultation were conducted in 17 experts.The obtained consultation opinions were summarized and revised,and the final version of index system was determined.Results The constructed standardized training and assessment index system for nurses working in lung puncture room included 4 level-Ⅰ indicators(training content,training methods,teaching staff,and assessment and evaluation),and 12 level-Ⅱindicators and 58 level-Ⅲ indicators.The positive coefficient was 100％in both rounds of consultation with experts.Of the two rounds of expert consultation,the expert judgment coefficients were 0.965 and 0.977 respectively,the familiarity coefficients were 0.859 and 0.859 respectively,and the authority coefficients were 0.912 and 0.918 respectively.After two rounds of expert consultation,the variation coefficients of indicators at all levels were 0-0.43 and 0-0.20 respectively.The Kendall's Coordination coefficients of the two rounds of expert consultation were 0.363(P＜0.001)and 0.554(P＜0.001)respectively.Conclusion The constructed standardized training and evaluation index system for nurses working in lung puncture room is scientific,practical,and operable,it can provide scientific standards for relevant assessment and training.

Objective To establish a human monocytic THP-1 macrophage-derived foam cell model and analyze the role of the α subunit of coatomer protein Ⅰ(α-COP)in apolipoprotein A-1(apoA-1)-mediated cholesterol efflux from foam cells.Methods THP-1 cells were induced to adhere using PMA(PMA group),followed by treatment with acetylated low-density lipoprotein(Ac-LDL)to generate macrophage-derived foam cells(Ac-LDL group).Subsequent incubation with apoA-1 formed the apoA-1 group.Cholesterol efflux rates mediated by apoA-1 and intracellular lipid accumulation were quantified through liquid scintillation counting and oil red O staining.The expression patterns of α-COP were systematically analyzed using quantitative real-time PCR(qPCR),Western blotting,and laser scanning confocal microscopy.THP-1 macrophage-derived foam cells mediated by apoA-1 were transduced with scrambled shRNA(Scr group)or α-COP-specific shRNA lentivirus(α-COP shRNA group)to assess the effects of α-COP knockdown on cholesterol efflux efficiency and total cellular cholesterol content.Subcellular localization of adipopoilin(ADFP)and cholesterol probe Fil-ipin Ⅲ staining patterns were visualized via laser scanning confocal microscopy.Bioinformatics analysis of α-COP expression profiles in carotid atherosclerotic plaques was performed using datasets from the GEO data-base.Results Compared with the Ac-LDL group,the cholesterol efflux rate in the apoA-1 group was signifi-cantly increased[(9.77±0.79)%vs.(2.74±0.37)%,P＜0.001].Oil red O staining demonstrated reduced lipid accumulation in foam cells of the apoA-1 group compared with the Ac-LDL group.The relative mRNA expression level of α-COP in the apoA-1 group was significantly higher than that in the Ac-LDL group(P＜0.001),with corresponding elevation in protein expression(P＜0.001).Fluorescence intensity analysis re-vealed increased mean fluorescence intensity of α-COP in the apoA-1 group compared with the Ac-LDL group.Following α-COP knockdown by shRNA,the apoA-1-mediated cholesterol efflux rate was significantly de-creased(P＜0.05)and total intracellular cholesterol levels were increased(P＜0.001)in the α-COP shRNA group compared with the Scr group.The α-COP shRNA group exhibited enhanced red fluorescence intensity of ADFP(P＜0.05)and increased blue fluorescence intensity of Filipin Ⅲ(P＜0.01)compared with the Scr group.Database analysis indicated that α-COP mRNA expression was lower in carotid atherosclerotic plaques than in normal arterial tissues,with reduced expression in advanced-stage plaques compared with early-stage plaques(P＜0.05).Conclusion α-COP participates in apoA-1-mediated cholesterol efflux from foam cells,and interference with α-COP expression results in reduced cholesterol efflux and increased intracellular lipid accumulation.

Conclusions:Patients with diabetes treated with insulin, with a duration of diabetes ≥10 years and accompanied by UACR ≥30 mg/g are at higher risk of developing DR than those with a single risk factor.

OBJECTIVE To investigate the vasodilatory effect of dimethyl sulfoxide(DMSO)on isolated aortic arteries and intrarenal arteries of rats and the mechanisms.METHODS ① Rat aortas and intrarenal arteries were pre-contracted with KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.Following equilibration,dimethyl sulfoxide(DMSO)was cumulatively administered at concentrations of 0.1%,0.3%,1.0%,3.0%and 10.0%.Changes in the vascular tension of aortic and intrarenal arterial rings were recorded using an isolated vessel tension measurement system.Rat intrarenal arteries were pre-contracted with KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.Cumulative additions of DMSO(3.0%and 10.0%)were administered as the control group.Following pre-contraction with each of the three stimulants,the voltage-gated potassium channel(Kv)inhibitor 4-AP(0.5 mmol·L-1)was incubated for 15 min.Cumulative additions of DMSO(3.0%and 10.0%)were then administered,and the vascular relaxation percentages induced by DMSO before and after treatment were calculated.Whole-cell patch-clamp recordings were performed on acutely isolated intrarenal arterial smooth muscle cells of rat to assess Kv currents during cumulative DMSO applications(0.1%,0.3%,1.0%and 3.0%).② Rat aortic smooth muscle cells(A7r5)were exposed to DMSO concentration of 0.0%(control),0.1%,0.3%,1.0%and 3.0%for 24 h.Intracellular reactive oxygen species(ROS)levels were detected using the DCFH-DA fluorescent probe.Malondialdehyde(MDA)content,catalase(CAT)activity,and superoxide dismutase(SOD)activity in A7r5 cells were measured by chemical colorimetry.Mitochondrial membrane potential was evaluated using the JC-1 fluorescent probe.RESULTS ① DMSO(0.1%-10.0%)dose-dependently relaxed rats aortic and intrarenal arteries pre-contracted with either KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.The values of maximum relaxation were(42.3±9.7)%,(73.2±8.4)%,(99.2±4.7)%and(84.0±1.9)%,(80.5±6.1)%and(81.2±4.4)%,respectively.Compared with the control group,vasorelaxation of DMSO on IRAs precontracted with U46619 was significantly attenuated by Kv inhibitor 4-AP.② Low concentrations(0.1%and 0.3%)of DMSO significantly increased Kv currents,while high concentrations(1.0%and 3.0%)of DMSO significantly decreased Kv currents.High concentrations(1.0%and 3.0%)of DMSO remarkablely increased ROS and MDA levels,but significantly decreased CAT activity,SOD activity and mitochondrial membrane potential in A7r5 cells.CONCLUSION DMSO(0.1%-10.0%)can relax rats aortal and intrarenal arteries in a concentra-tion-dependent manner,and the mechanism may be related to Kv,oxidative stress and mitochondrial damage.
