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 investigate the role of 4-week high-intensity interval training (HIIT) in modulating the metabolic homeostasis of the pyruvate-lactate axis in the hippocampus of rats with chronic unpredictable mild stress (CUMS) to improve their depressive-like behavior. MethodsForty-eight SPF-grade 8-week-old male SD rats were randomly divided into 4 groups: the normal quiet group (C), the CUMS quiet group (M), the normal exercise group (HC), and the CUMS exercise group (HM). The M and HM groups received 8 weeks of CUMS modeling, while the HC and HM groups were exposed to 4 weeks of HIIT starting from the 5th week (3 min (85%-90%) S_max+1 min (50%-55%) S_max, 3-5 cycles, S_max is the maximum movement speed). A lactate analyzer was used to detect the blood lactate concentration in the quiet state of rats in the HC and HM groups at week 4 and in the 0, 2, 4, 8, 12, and 24 h after exercise, as well as in the quiet state of rats in each group at week 8. Behavioral indexes such as sucrose preference rate, number of times of uprightness and number of traversing frames in the absenteeism experiment, and other behavioral indexes were used to assess the depressive-like behavior of the rats at week 4 and week 8. The rats were anesthetized on the next day after the behavioral test in week 8, and hippocampal tissues were taken for assay. LC-MS non-targeted metabolomics, target quantification, ELISA and Western blot were used to detect the changes in metabolite content, lactate and pyruvate concentration, the content of key metabolic enzymes in the pyruvate-lactate axis, and the protein expression levels of monocarboxylate transporters (MCTs). Results4-week HIIT intervention significantly increased the sucrose preference rate, the number of uprights and the number of traversed frames in the absent field experiment in CUMS rats; non-targeted metabolomics assay found that 21 metabolites were significantly changed in group M compared to group C, and 14 and 11 differential metabolites were significantly dialed back in the HC and HM groups, respectively, after the 4-week HIIT intervention; the quantitative results of the targeting showed that, compared to group C, lactate concentration in the hippocampal tissues of M group, compared with group C, lactate concentration in hippocampal tissue was significantly reduced and pyruvate concentration was significantly increased, and 4-week HIIT intervention significantly increased the concentration of lactate and pyruvate in hippocampal tissue of HM group; the trend of changes in blood lactate concentration was consistent with the change in lactate concentration in hippocampal tissue; compared with group C, the LDHB content of group M was significantly increased, the content of PKM2 and PDH, as well as the protein expression level of MCT2 and MCT4 were significantly reduced. The 4-week HIIT intervention upregulated the PKM2 and PDH content as well as the protein expression levels of MCT2 and MCT4 in the HM group. ConclusionThe 4-week HIIT intervention upregulated blood lactate concentration and PKM2 and PDH metabolizing enzymes in hippocampal tissues of CUMS rats, and upregulated the expression of MCT2 and MCT4 transport carrier proteins to promote central lactate uptake and utilization, which regulated metabolic homeostasis of the pyruvate-lactate axis and improved depressive-like behaviors.

ObjectiveThis study aimed to investigate the effects of 4-week high-intensity interval training (HIIT) on synaptic plasticity in the prefrontal cortex (PFC) of rats exposed to chronic unpredictable mild stress (CUMS), and to explore its potential mechanisms. MethodsA total of 48 male Sprague-Dawley rats were randomly divided into 4 groups: control (C), model (M), control plus HIIT (HC), and model plus HIIT (HM). Rats in groups M and HM underwent 8 weeks of CUMS to establish depression-like behaviors, while groups HC and HM received HIIT intervention beginning from the 5th week for 4 consecutive weeks. The HIIT protocol consisted of repeated intervals of 3 min at high speed (85%-90% maximal training speed, S_max) alternated with one minute at low speed (50%-55% S_max), with 3 to 5 sets per session, conducted 5 d per week. Behavioral assessments and tail-vein blood lactate levels were measured at the end of the 4th and 8th weeks. After the intervention, rat PFC tissues were collected for Golgi staining to analyze synaptic morphology. Enzyme-linked immunosorbent assays (ELISA) were employed to detect brain-derived neurotrophic factor (BDNF), monocarboxylate transporter 1 (MCT1), lactate, and glutamate levels in the PFC, as well as serotonin (5-HT) levels in serum. Additionally, Western blot analysis was conducted to quantify the expression of synaptic plasticity-related proteins, including c-Fos, activity-regulated cytoskeleton-associated protein (Arc), and N-methyl-D-aspartate receptor 1 (NMDAR1). ResultsCompared to the control group (C), the CUMS-exposed rats (group M) exhibited significant reductions in sucrose preference rates, number of grid crossings, frequency of upright postures, and entries into and duration spent in open arms of the elevated plus maze, indicating marked depressive-like behaviors. Additionally, the group M showed significantly reduced dendritic spine density in the PFC, along with elevated levels of c-Fos, Arc, NMDAR1 protein expression, and increased concentrations of lactate and glutamate. Conversely, BDNF and MCT1 contents in the PFC and 5-HT levels in serum were significantly decreased. Following HIIT intervention, rats in the group HM displayed considerable improvement in behavioral indicators compared with the group M, accompanied by significant elevations in PFC MCT1 and lactate concentrations. Furthermore, HIIT notably normalized the expression levels of c-Fos, Arc, NMDAR1, as well as glutamate and BDNF contents in the PFC. Synaptic spine density also exhibited significant recovery. ConclusionFour weeks of HIIT intervention may alleviate depressive-like behaviors in CUMS rats by increasing lactate levels and reducing glutamate concentration in the PFC, thereby downregulating the overexpression of NMDAR, attenuating excitotoxicity, and enhancing synaptic plasticity.

BACKGROUND:The incidence of osteoporosis significantly increases in the patients with rheumatoid arthritis,and it remains unclear whether the presence of a large number of immune complexes in serum promotes the onset and development of osteoporosis. OBJECTIVE:To investigate the correlation between serum immune complexes and osteoporosis in patients with rheumatoid arthritis. METHODS:(1)Clinical trial:Serum and clinical data of 50 healthy controls and 50 patients with untreated rheumatoid arthritis were collected and retrospectively analyzed.Total immune complex level in serum was compared between two groups.Correlation of serum total immune complexes with bone mineral density,bone turnover markers and other clinical indicators in patients with rheumatoid arthritis was analyzed.(2)Cell experiment:Peripheral blood mononuclear cells from healthy volunteers were isolated and cultured,and divided into four groups:rheumatoid arthritis group was added with total immune complex suspension from rheumatoid arthritis patients;normal control group was added with total immune complex suspension from healthy medical checkups;positive control group was added with α-MEM medium containing macrophage colony-stimulating factor and receptor activator of nuclear factor-kappa B ligand,and negative control group was added with α-MEM medium.Tartrate-resistant acid phosphatase staining was performed to observe the formation of osteoclasts after 7 days of treatment, RESULTS AND CONCLUSION:(1)Clinical trial:The total immune complex and serum alkaline phosphatase levels in patients with rheumatoid arthritis were significantly higher than those in health controls(P＜0.01,P＜0.05).Pearson correlation analysis showed that serum total immune complex level was positively correlated with erythrocyte sedimentation rate(r=0.330,P=0.019),serum alkaline phosphatase(r=0.545,P=0.001),anti-cyclic citrullinate peptide(r=0.377,P=0.007)and c-terminal telopeptide of type Ⅰ collagen(r=0.738,P=0.001),and negatively correlated with lumbar bone mineral density(r=-0.595,P=0.001)in patients with rheumatoid arthritis.Binary Logistic regression analysis showed that age[odds ratio(OR)=1.086,95%confidence interval(CI)(1.022,1.154),P=0.008],anti-cyclic citrullinate peptide[OR=1.002,95%CI(0.999,1.005),P=0.035],c-terminal telopeptide of type Ⅰ collagen[OR=0.141,95%CI(0.015,8.900),P=0.008]and serum total immune complexes[OR=2.895,95%CI(1.228,6.827),P=0.001]were the influencing factors for abnormal bone mass(reduced bone mass or osteoporosis)in patients with rheumatoid arthritis.(2)Cell experiment:Tartrate-resistant acid phosphatase positive osteoclasts were observed in the positive control group,normal control group and rheumatoid arthritis group,and there were more osteoclasts in the rheumatoid arthritis group than in the normal control group(P＜0.01).To conclude,serum total immune complexes can be used as a potential serologic predictor of rheumatoid arthritis complicated with osteoporosis,and removing immune complexes in serum or interfering with the binding of immune complexes to their receptors may be an effective means for the prevention and treatment of rheumatoid arthritis complicated with osteoporosis.

Objective:To analyze the iodine nutritional status of children aged 8 - 10 in Tongren City, Guizhou Province, and provide a basis for scientific iodine supplementation for children.Methods:From 2020 to 2022, a systematic sampling method was adopted in 10 districts and counties of Tongren City. Each year, each district and county was divided into 5 districts based on east, west, south, north, and center. One township (street) was selected from each district, and 40 non boarding students aged 8 to 10 were selected from each township (street) to measure the iodine content of household salt and urine samples. The content of salt iodine in children of different yesas as well as the distribution of urine iodine in children of different districts and counties and different genders were analyzed and compared. Additionally, B-ultrasound was used to measure the thyroid volume of some children and the situation of thyroid enlargement was analyzed.Results:From 2020 to 2022, a total of 6 000 salt samples were collected and monitored from children's households, and 5 989 samples of iodized salt were detected, the coverage rate of iodized salt was 99.8%; and 5 750 samples of qualified iodized salt were found, the qualified rate of iodized salt was 96.0%, the consumption rate of qualified iodized salt was 95.8%; and the median salt iodine was 27.3 mg/kg, the difference in the median salt iodine among children between different years was statistically significant ( H = 10.04, P < 0.001). A total of 6 000 urine samples from children were tested, the median urinary iodine was 225.2 μg/L, the median urinary iodine among children in different districts and counties were statistically significantly different ( H = 85.73, P < 0.001); 3 077 male and 2 923 female urine samples were tested, and the median urinary iodine between different genders was statistically significant different ( Z = - 67.10, P < 0.001). The median urinary iodine of male samples were higher than those of female samples(227.8 vs 222.9 μg/L). The thyroid gland of 2 000 children was examined, and the rate of goiter was 1.0% (21/2 000). Conclusions:From 2020 to 2022, the consumption rate of qualified iodized salt, urinary iodine content and goiter rate of children in Tongren City have all met the national standard for eliminating iodine deficiency disorders. The overall iodine nutrition level exceeds the appropriate amount (urinary iodine of 200 - 299 μg/L).

Colorectal cancer is a common clinical malignant tumor. As the main therapeutic method of colorectal cancer, radiotherapy has a good inhibitory effect on tumor progression. In recent years, because of its good physical and biological advantages, carbon ion has shown better clinical efficacy than traditional radiotherapy in the treatment of local recurrence or distant metastasis of colorectal cancer. In this article, basic and clinical studies related to the efficacy of carbon ion therapy for the recurrence of colorectal cancer in recent years were reviewed, aiming to provide theoretical basis for preventing and reducing adverse reactions after radiotherapy and prolonging the survival of colorectal cancer patients.

Objective To explore the key genes and long non-coding RNAs(lncRNAs)associated with Parkinson's disease(PD).Methods Peripheral blood plasma samples were collected from 6 PD patients and 6 healthy individuals.The mRNA and lncRNA expression profiles were detected using ceRNA microarray technology,and the differentially expressed genes were analyzed using bioinformatics methods.The differentially expressed mRNAs transcribed within 10 kb upstream or downstream of the differentially expressed lncRNAs were defined as potential cis-regulatable(Cis)target genes of the lncRNAs.A PD-specific protein-protein interaction network(PPI)was constructed.Competitive endogenous RNA(ceRNA)networks were also constructed using the differential lncRNAs with mRNAs and known microRNAs.Using MPP+-treated SH-SY5Y cells as a PD cell model,the expressions of the key lncRNAs and their functions were examined.Results We identified 316 genes and 986 lncRNAs showing significant differential expressions in PD patients(P<0.05).The differentially expressed mRNAs and the potential cis-regulatable target genes of these lncRNAs were functionally annotated using GO and KEGG enrichment analysis,and the targeting relationship of the differentially expressed mRNAs and lncRNAs with microRNAs were predicted.Analysis of the ceRNA networks constructed based on the differentially expressed lncRNAs suggested that lnc-MTG2-1:1,lnc-CTSD-5:1,lnc-PCCA-3:1,lnc-VTCN1-3:1,lnc-ZNF25-7:1,and lnc-DAZ3-1:1 might be the key lncRNAs in PD.In MPP+-treated SH-SY5Y cells,the expression of lnc-CTSD-5:1 showed the most significant changes,and silencing lnc-CTSD-5:1 obviously restored the expression level of tyrosine hydroxylase.Conclusion PD patients have significant changes in plasma lncRNA expression profile,and the differentially expressed genes and lncRNAs found in this study may provide new clues for exploring the pathogenesis and identifying potential biomarkers of PD.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.
