Objective:To investigate the clinical efficacy and major complications (postoperative hemorrhage and cerebral edema) of 3 surgical methods in spontaneous supratentorial intracerebral hemorrhage (SSICH).Methods:A retrospective analysis was performed; 294 patients with SSICH admitted to Department of Neurosurgery, Renmin Hospital of Wuhan University from December 2018 to October 2021 were selected. According to different surgical methods, these patients were divided into neuroendoscopic hematoma removal group ( n=126), stereotactic drilling and drainage group ( n=98), and craniotomy hematoma removal group ( n=70). The surgical efficacy and complications in the 3 groups were analyzed, and the postoperative residual hematoma and edema volumes were quantitatively calculated based on 3D Slicer software. Results:The hematoma evacuation rate in the neuroendoscopic hematoma removal group, stereotactic drilling and drainage group, and craniotomy hematoma removal group was 86.25%±2.27%, 44.45%±3.61%, and 75.45%±2.89%, respectively; Glasgow coma Scale scores at discharge were 13.51±1.28, 11.24±2.17 and 10.25±2.56, respectively; postoperative hemorrhage incidence was 16.1%, 26.0% and 22.9%, respectively; postoperative residual hematoma volume was (18.90±12.33) mL, (25.75±11.43) mL and (22.91±7.93) mL, and postoperative peak edema volume was (37.43±11.07) mL, (39.54±9.43) mL, and (42.26±10.94) mL, respectively; percentage of patients with peak edema on 3-5 days after surgery was 31.0%, 65.3% and 68.6%; the diameter of edema zone was (20.04±2.98) mm, (24.12±5.85) mm and (23.59±3.81) mm, respectively, on 7 days after surgery; percentage of patients with edema resolution was 45.2%, 24.5%, 42.9% and 76.2%, 57.1%, 62.9%, respectively, on 9-11 days and 12-14 days after surgery; these indexes in the neuroendoscopic hematoma removal group were significantly different compared with those in the other two groups ( P<0.05). Conclusion:Compared with stereotactic drilling and drainage or craniotomy hematoma removal, neuroendoscopic surgery can effectively remove the hematoma and reduce the occurrences of postoperative hemorrhage and brain edema.

Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

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.

Allergic diseases seriously affect people's health,throughout the whole life cycle,from chil-dren to adults and then to the elderly allergy,can be lifelong onset,and need comprehensive prevention and treatment of the whole life cycle.Its occurrence and development have certain rules,it is usually first manifes-ted as atopic dermatitis in infants and young children,and then gradually develops into food allergy,allergic rhinitis(AR),and allergic asthma.Intervention in atopic dermatitis and or reducing the sensitization of food allergens can inhibit the allergic process and reduce the occurrence of AR and allergic asthma.Therefore,inter-vening and blocking the allergic processes is the key to the prevention and treatment of allergic diseases.This article focuses on the comprehensive intervention measures of allergic diseases(including health education,al-lergen intervention,nutrition intervention,daily nursing,psychological intervention)and disease monitoring,in order to promote the development of the prevention and treatment of allergic diseases.

Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling.Here,we focused on the role of Semaphorin 3A(Sema3A),expressed by sensory nerves,in mechanical loads-induced bone formation and nerve withdrawal using orthodontic tooth movement(OTM)model.Firstly,bone formation was activated after the 3rd day of OTM,coinciding with a decrease in sensory nerves and an increase in pain threshold.Sema3A,rather than nerve growth factor(NGF),highly expressed in both trigeminal ganglion and the axons of periodontal ligament following the 3rd day of OTM.Moreover,in vitro mechanical loads upregulated Sema3A in neurons instead of in human periodontal ligament cells(hPDLCs)within 24 hours.Furthermore,exogenous Sema3A restored the suppressed alveolar bone formation and the osteogenic differentiation of hPDLCs induced by mechanical overload.Mechanistically,Sema3A prevented overstretching of F-actin induced by mechanical overload through ROCK2 pathway,maintaining mitochondrial dynamics as mitochondrial fusion.Therefore,Sema3A exhibits dual therapeutic effects in mechanical loads-induced bone formation,both as a pain-sensitive analgesic and a positive regulator for bone formation.
