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 explore the effectiveness and safety of polyglycolic acid(PGA)and hydroxypropyl methylcellulose(HPMC)composite materials for suturing after canine sleeve gastrectomy.Methods A total of 36 healthy Beagle dogs were randomly divided into experimental group and control group in a 1∶1 male-to-female ratio.The experimental group underwent gastric sleeve resection with PGA+HPMC composite material for suture reinforcement,while the control group used NV-ET-M60E-2 suture material.Postoperative monitoring included survival status,food intake,and body temperature changes.Venous blood samples were collected before surgery,3 days after surgery,and before euthanasia for routine blood tests.At 2,4,and 8 weeks postoperatively,six dogs were euthanized at each time point for histological examination,hard tissue pathological evaluation,and safety assessment of the heart,liver,spleen,lungs,and kidneys.Results There were no significant differences in blood routine test results between the control group and the experimental group(P＞0.05).Before dissection,the percentage of basophils was significantly higher in the control group than in the experimental group(P=0.015).At 2 weeks after surgery,the severity of liver cell edema in the control group was higher than in the experimental group(P=0.036).However,the two groups did not significantly differ in the histological examination results of the heart,liver,spleen,lungs,or kidneys at other time points(P＞0.05).Hard tissue pathological slice results at 2,4,and 8 weeks after surgery showed no material residue in either group by the 8th week,and there were no significant differences in inflammation and necrosis scores or fibrosis/fat infiltration totals between the two groups(P＞0.05).Inflammation scores and fibrosis/fat infiltration totals at 8 weeks post-operation were significantly lower than those at 2 weeks post-operation(P＜0.05).During the experiment,no near-death phenomena occurred in either group,and no fever or refusal to eat was observed within 3 days after surgery.At dissection,the Beagle dogs appeared normal with glossy fur and no abnormal secretions.Conclusion PGA+HPMC composite materials can be effectively degraded and used as non-toxic suture fixation materials for wound suturing after sleeve gastrectomy,providing a theoretical basis for their clinical application.

BackgroundWith the exacerbation of population aging， the number of elderly patients with mental disorders has increased significantly. The high prevalence of pulmonary infection in the aging population has largely contributed to the increased medical burdens and mortality rate， so preventing pulmonary infection in elderly patients with mental disorders has become a critical challenge in clinical practice. www.crd.york.ac.uk/PROSPERO注册号：CRD42024553735 ObjectiveTo investigate the prevalence and influencing factors of pulmonary infection in elderly patients with mental disorders， so as to provide references for preventing the occurrence of pulmonary infection in this population. MethodsOn July 1， 2024， computer searches of CNKI， China Biomedical Literature Database （CBM）， Wanfang， PubMed， Web of Science， Embase， Cochrane Library and Ovid were conducted from the inception of each database to June 2024. Two researchers independently conducted literature screening， data extraction and quality assessment. Meta-analysis was performed using Stata 16.0. ResultsA total of 17 literature （14 in Chinese， 3 in English） involving 75 724 elderly patients with mental disorders were included. Meta analysis revealed that the incidence rate of pulmonary infection in elderly patients with mental disorders was 20.8% （95% CI： 0.154~0.263）. Subgroup analysis indicated that the incidence rates of pulmonary infection among patients with dementia， schizophrenia， depression and unspecified mental disorders were 21.9% （95% CI： 0.182~0.256）， 20.6% （95% CI： 0.129~0.283）， 18.4% （95% CI： 0.136~0.232） and 5.2% （95% CI： 0.430~0.062）， respectively. In terms of influencing factors， the following were identified as risk factors for pulmonary infection in elderly patients with mental disorders： comorbid diabetes mellitus （OR=1.29， 95% CI： 1.24~1.34）， prolonged bed rest （OR=2.41， 95% CI： 2.10~2.76）， dysphagia （OR=1.76， 95% CI： 1.53~2.03）， smoking history （OR=6.27， 95% CI： 5.97~6.59）， irrational use of antibiotics （OR=2.10， 95% CI： 1.79~2.45）， hypoalbuminemia （OR=1.57， 95% CI： 1.35~1.83）， duration of illness （OR=2.05， 95% CI： 1.79~2.36）， age （OR=9.04， 95% CI： 8.44~9.68）， length of hospital stay （OR=2.68， 95% CI： 1.65~4.34）， use of proton pump inhibitors （OR=1.10， 95% CI： 1.06~1.14）， history of chronic lung disease （OR=1.50， 95% CI： 1.43~1.57）， poor oral hygiene （OR=3.66， 95% CI： 1.01~13.23）， comorbid tumors （OR=3.12， 95% CI： 2.18~4.48）， more than two somatic complications （OR=4.01， 95% CI： 1.08~14.86）， invasive procedures （OR=3.31， 95% CI： 1.81~6.04） and disorders of consciousness （OR=5.57， 95% CI： 2.18~14.24）. ConclusionElderly patients with mental disorders suffer a relatively high prevalence rate of pulmonary infection， and its prevalence rate varies among different types of mental disorders， with the highest rate being observed in patients with dementia. The factors contributing to the development of pulmonary infection are found to include age， duration of illness， smoking history， comorbid somatic complications， dysphagia， disorders of consciousness， hypoalbuminemia， prolonged bed rest， oral hygiene status， irrational use of antibiotics， use of proton pump inhibitor， length of hospital stay and invasive procedures. ［www.crd.york.ac.uk/PROSPERO number： CRD42024553735］

Depression is a severe mental illness. Although existing antidepressant medications have shown efficacy in many patients, a significant proportion show poor responses to current treatments, necessitating the need for novel therapeutic approaches. Photobiomodulation (PBM), an emerging physical therapy, has recently shown promising efficacy in the treatment of depression, as indicated by two systematic reviews, and is characterized by high safety and good tolerability. However, challenges remain in areas such as light delivery techniques and optimization of treatment parameters. This review summarizes the antidepressant mechanisms of PBM, various methods of light transmission, and recent research progress on its application in the treatment of depression. It also discusses issues related to safety, tolerability, and impact of specific parameters, aiming to provide insights and recommendations for future research on PBM as a therapy for depression.

Objective:To investigate clinical curative effect of multiple composite tissues replantation with microsurgical technique in single hand.Methods:From May 2008 to December 2021, the clinical data of patients who underwent multiple composite tissue replantation in single hand in Chongming Hospital Affiliated to Shanghai University of Medicine & Health Sciences and Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, were retrospectively analyzed. According to the severed site, anatomical level, the injury cause, the severity of injury, the size of severed tissue, and replantation conditions (such as blood vessels for anastomosis), the severed tissue was evaluated and carried out modified classification (type Ⅰ-Ⅳ) before the operation, and the surgical plan was designed. The severed composite tissue was debrided in emergency, the severed bone and muscle tissue were fixed, and the arteries, veins and nerves were anastomosed by microsurgical technique under a high-power microscope. The ratio of arteries to veins was 1∶1-1∶2. If enough arteries and veins could not be found, arteriovenous shunt could be used to form arterial venous flap or venous arterialized flap, or form artery flap by just artery anastomosis, or form venous flap by just vein anastomosis. Then skin tissue was sutured after recanalization. After the operation, the patients received specialized treatment and guided rehabilitation exercise. The wound healing of hand, skin color, skin quality, swelling degree, sensation, pain degree of joint, and activity function were followed up after the operation. At the last follow-up, the patient’s self-evaluation of the treatment effect was divided into three levels: satisfactory, average, and unsatisfactory. One chief physician and one doctor-in-charge were responsible for the comprehensive evaluation of curative effect, according to the assessment standard for upper limb function issued by Chinese Medical Association of Hand Surgery. 80-100 points were excellent, 60-79 points were good, 40-59 points were fair, and <40 points were poor.Results:A total of 94 severed composite tissues in 35 patients, including of 20 male patients and 15 female patients were enrolled. The average age was 36.4 years (range, 16-65 years). Fifty severed tissues in 18 cases were classified into type Ⅰ, 40 severed tissues in 15 cases type Ⅱ, 4 severed tissues in 2 cases type Ⅲ. Among the 35 cases, 1 case of thumb pulp severed tissue was necrotic at the edge (0.3 cm×0.5 cm) due to local contusion, 1 case of index finger lateral severed tissue was necrotic at the edge (0.3 cm×0.8 cm) due to local avulsion injury, and healed after dressing change, and the other replanted composite tissue survived. The patients were followed up for 3 to 65 months (average, 18.5 months). The wounds were completely healed, and the color, elasticity, and quality of the replanted tissue was close to the surrounding normal skin. There was no obvious swelling or atrophy deformity of the hands. According to the patients’ self-assessment, 31 cases were satisfied and 4 cases were average. Comprehensive evaluation of hand function and appearance: excellent in 23 cases, good in 9 cases, fair in 3 cases, excellent and good rate was about 91.4% (32/35).Conclusion:Though multiple composite tissues replantation with microsurgical technique in single hand is difficult, and vascular anastomosis technical requirement is high, once surgery succeeds, the function and appearance can get good recovery, and patient satisfaction is also relatively high.
