Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

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 assess the feasibility and security the orientation of foreign bodies using a portable X-ray machine in computer-aided navigation surgery.Methods:A model with a metallic foreign body was constructed.Under the fluoroscopy of a portable X-ray machine,4 points on 2 straight lines passing through the tip of the foreign body were recorded by the navigation e-quipment,and subsequently,the midpoints of the common perpendicular segments of the 2 lines were calculated as the coordinates of the foreign body(Bilinear Method).2 operators measured the coordinates of the foreign body 10 times and compared the measured coordinates of the foreign body with the actual coordinates of the foreign body in order to analyze the accuracy of the Bilinear Method.Radiation doses to model area and operators at different locations were measured using ionizing radiation detectors.Results:The ac-curacy of the Bilinear Method for measuring foreign body coordinates was(1.98±0.77)mm,and that of the 2 operators was 1.55±0.68 and 2.40±0.36 respectively(P=0.02).The radiation dose was(221.45±50.15)μSv in the model and(4.44±1.35)μSv in the operator's chest.Conclusion:The accuracy of the coordinates of the foreign body intraoperation measured by Bilinear Method meets general clinical needs,and different operators may produce different accuracy.The radiation dose is small.

Objective:To analyze intestinal microecological differences and their correlation with psychological status in patients with constipated irritable bowel syndrome(IBS-C)and functional constipation(FC).Methods:A total of 160 patients with IBS-C and FC attending the outpatient and inpatient departments of the Department of Gastroenterology at the General Hospital of Ningxia Medical University from January 2021 to January 2024 were selected and grouped according to the type of disease into the IBS-C group(80 patients)and the FC group(80 patients),and 80 patients who had a health checkup during the same period were selected as the control group.Fresh fecal specimens were taken from all subjects,and 16S rRNA sequencing was used to detect the intestinal flora,and the indices of intestinal microecological diversity(Ace index,Chao index,Shannon index,and Sobs index)were detected,and the psychological state of the subjects was assessed by using the Self-Assessment Scale for Anxiety(SAS)and the Self-Depression Scale(SDS).Pearson's correlation method was used to analyze the correlation between intestinal microecology and correlation with psychological state in IBS-C and FC patients.Result:Bifidobacteria and Lactobacillus levels were lower in both the FC and IBS-C groups compared with the control group,and the decrease was more pronounced in the IBS-C group(P＜0.05).Enterobacteriaceae and Enterococci contents were higher in patients in the FC and IBS-C groups(P＜0.05),with the greatest increase in the IBS-C group(P＜0.05);Microbial diversity analysis showed that there were differences in Ace,Chao,Shannon and Sobs indices among the three groups(P＜0.05).All diversity indices were lower in the FC and IBS-C groups than in the control group,and the degree of reduction was more pronounced in the IBS-C group than in the FC group(P＜0.05);The SAS and SDS scores of both FC and IBS-C groups were higher than those of the control group,and the scores of the IBS-C group were higher than those of the FC group(P＜0.05);correlation analysis showed that,in the IBS-C and FC groups,Bifidobacterium and Lactobacillus,Ace index,Chao index,Shannon index,and Sobs index were negatively correlated with SAS and SDS scores.Enterobacteriaceae and Enterococci were positively correlated with SAS and SDS scores(P＜0.05).Conclusion:There are possible differences in the gut microbiota between IBS-C and FC patients.The imbalance of gut microbiota is more significant in IBS-C patients,and gut microbiota is closely related to psychological status.Clinical treatment of IBS-C and FC should pay attention to the regulation of gut microbiota and intervention of psychological status.

Objective:To explore the aperiodic components(1/f slopes)and their associations with cognitive impairment in patients with schizophrenia.Methods:Nineteen patients with schizophrenia according to the Interna-tional Statistical Classification of Diseases and Related Health Problem,Tenth Revision(ICD-10)and 21 normal controls were administrated the total Brief Assessment of Cognition in Schizophrenia(BACS)to measure the cogni-tive performance.The 5-minute eyes-closed and eyes-open resting EEG signals were collected and parameterized in-to aperiodic components(1/f slope).Finally,Pearson correlation was used to examine the relationships between the 1/f slope and cognition assessment scores.Results:The patients with schizophrenia had higher 1/f slope compared to HC on central location of scalp(P＜0.05).The vocal memory scores showed a significantly positive relation with 1/f slopes in patients with schizophrenia(anterior location:r=-0.68,P＜0.05;central location:r=-0.44,P＜0.05),but a significantly negative relation in normal controls(anterior location:r=0.57,P＜0.05;posterior lo-cation:r=0.54,P＜0.05).Conclusion:The 1/f slopes of EEG in schizophrenia were steeper than normal control,suggesting its strong cognitive functional significance and complex mechanisms in schizophrenia.

Objective:To summarize the clinical characteristics and follow-up data of premature infants with metabolic bone disease（MBDP）complicated with spontaneous fracture，and to provide a reference for clinical diagnosis and treatment.Methods:The clinical characteristics,physical growth,and development of eight premature infants with MBDP and spontaneous fracture admitted to the Neonatology Department of the Third Affiliated Hospital of Guangzhou Medical University from January 2020 to December 2022 were retrospectively analyzed.Results:Among the eight cases，six were male and two were female，with gestational ages ranging from 24 +6 to 28 +5 weeks and birth weights ranging from 495 to 1 070 grams.They were complicated with multiple serious complications associatied with premature birth.All patients had a history of drug use,including glucocorticoids,diuretics，caffeine,or sedation，as well as prolonged mechanical ventilation,parenteral nutrition，and multiple blood transfusions.During hospitalization，the normal blood calcium was monitored in all eight premature infants，and the blood phosphorus levels were all below 1.8 mmol/L，serum alkaline phosphatase（ALP）levels exceeded 500 IU/L，with five cases exceeding 900 IU/L.The diagnostic time of MBDP ranged from 61 to 157 days after birth.All premature infants were complicated with fractures of different parts，and the diagnostic time of fractures ranged from 74 to 157 days after birth.They were actively treated with calcium，phosphorus and vitamin D，and were discharged from the hospital after the fracture recovery.The hospitalization time was 95 to 226 days.At discharge，six premature infants had retarded growth in body length and/or weight，and four premature infants still had retarded growth to varying degrees at the correct gestational age of 12 months. Conclusion:Early screening and prevention of MBDP should be carried out in extremely and very premature infants to prevent the occurrence of spontaneous fractures.Furthermore,follow-up management and monitoring after discharge should be strengthened to improve their prognosis.

Objective:To investigate the feasibility of stapled closure of the internal fistula orifice in anal fistula (SCIA) combined with catheter drainage in the extra-sphincteric space in the treatment of high complex anal fistula.Methods:Methods Surgical procedure: Under combined spinal-epidural anesthesia, a submucosal purse-string suture was placed above the dentate line, and the stapler was inserted to close the internal opening. The fistulous tract was dissected from the external opening toward the cranial side and excised along its path to the level of the levator ani muscle, followed by placement of catheter drainage in the extra-sphincteric space.Results:A retrospective analysis was conducted on the clinical data of a 40-year-old male patient with a high-position complex anal fistula, who underwent SCIA combined with catheter drainage in the extra-sphincteric space at the Department of Colorectal Surgery, The First Affiliated Hospital of Guangzhou University of Chinese Medicine in December 2024. The surgery was successful with minimal intraoperative bleeding, a complete anastomosis, and thorough fistula tract dissection. There was no sphincter injury occurred, and the catheter drainage was unobstructed. The patient was discharged on postoperative day 8. Postoperative follow-up visits were conducted at 2 months and 6 months after surgery. The patient had no symptoms such as pain, purulent discharge, or pruritus. MRI scans of the anal canal (both plain and contrast-enhanced) at 2 months and 6 months showed no recurrence of the fistula. The Wexner fecal incontinence score was 0, indicating normal bowel control, and the Garg score was less than 8, suggesting fistula healing and low probability of recurrence.Conclusion:SCIA combined with catheter drainage in the extra-sphincteric space is a safe and feasible procedure for the treatment of high complex anal fistula.
