Aim To systematically elucidate the molecular regulatory network of thermogenic function in brown adipose tissue(BAT)through multi-omics integrative analysis,to discover novel thermogenic regulatory genes and provide novel therapeutic targets for metabolic disorders.Methods A novel methodology for screening key genes regulating thermogenesis in BAT was constructed:First,differential expression analysis was performed on bulk RNA-seq data from murine BAT.Genes meeting the thresholds of ABS(log2FoldChange)＞1 and Padj＜0.05 were identified as differentially expressed genes.Intersectional analysis was then applied to obtain consensus upregulated and downregulated gene sets.Subsequently,scRNA-seq data of brown adipocytes were partitioned into high-expression group and low-expression group based on the expression levels of candidate genes.Differential analysis and gene set enrichment analysis(GSEA)were conducted between these groups to assess the correlation between candidate genes and thermogenic function.Finally,ex-perimental validation of selected candidate genes was performed using quantitative real-time PCR and Western blot.Results Bioinformatics analysis identified 65 thermogenesis-positive correlated genes and 7 thermogenesis-negative corre-lated genes.Subsequent quantitative PCR validation demonstrated that candidate genes Mfsd2a,Me1,Slc25a34,Pfkp,Ankrd9,Hsd17b12,Aldoa,Ctsz and Pcyt2 exhibited upregulation exceeding 5-fold,while Pid1 and Angpt1 showed down-regulation over 50％.All observed expression changes demonstrated statistical significance(P＜0.01)through rigorous hypothesis testing.These findings highlight the potential involvement of these genes in thermogenic regulation,warranting further functional investigations to elucidate their molecular mechanisms in energy metabolism pathways.Conclusions This study established a novel"computational screening → in silico knockout → experimental validation"paradigm for tar-get discovery,systematically unveiling the molecular network involved in BAT thermogenic regulation.This methodology is equally applicable for identifying key regulatory genes in other physiological or pathological processes.The study identi-fied 11 core genes that may play pivotal regulatory roles during BAT thermogenic activation,which could potentially offer novel pharmacological intervention targets to improve energy metabolism and treat obesity-related complications.

Objective:To explore the clinical efficacy of the San Diego osteotomy in treating developmental dysplasia of the hip (DDH) in children.Methods:A retrospective analysis was conducted on 33 pediatric cases of posterolateral acetabular dysplasia treated with the San Diego osteotomy at the 920th Hospital of the People's Liberation Army Joint Logistics Support Force in China from August 2018 to August 2022. The cohort included 3 males (4 hips) and 30 females (36 hips), with an average age of 4.9±1.4 years (range, 2-8 years). Among these, 32 cases (38 hips) were diagnosed with DDH, and 1 case (2 hips) with paralytic dislocation of the hip. According to the T?nnis classification, 3 hips were classified as type II, 25 hips as type III, and 12 hips as type IV. The San Diego osteotomy technique was utilized to enhance the posterior lateral acetabular coverage, combined with femoral osteotomy to adjust the hip abduction, flexion, and adduction angles. Postoperative outcomes were assessed using the modified Severin radiographic classification and the McKay grading system.Results:All 33 patients were followed up for an average of 37.70±18.44 months (range, 12-74 months). No cases of postoperative hip redislocation or residual acetabular underdevelopment were observed. The hip abduction angle improved from 24.98°±3.48° at 6 weeks postoperatively to 37.28°±4.63° at the 3-month follow-up, and 64.05°±3.82° at the 6-month follow-up, with a statistically significant difference ( F=77.327, P<0.001). The hip flexion angle increased from 26.34°±5.05° at 6 weeks postoperatively to 76.53°±4.38° at 3 months, and 106.47°±2.29° at 6 months, also showing a statistically significant difference ( F=54.377, P<0.001). The hip adduction angle progressed from 1.73°±1.18° at 6 weeks postoperatively to 12.33°±1.97° at 3 months, and 29.03°±4.17° at 6 months, with a significant difference ( F=45.162, P<0.001). The McKay hip joint grading system indicated 11 excellent, 20 good, and 9 acceptable outcomes, yielding an overall excellent and good rate of 78%. The Severin radiographic grading revealed 16 hips at grade I and 24 hips at grade II. Five patients (5 hips) experienced transient vascular compromise of the femoral head at 3 months postoperatively, which resolved after a 1-month non-weight-bearing period. At the final follow-up, one patient had residual femoral head enlargement in the right hip, while the remaining 32 cases showed satisfactory ossification and remodeling of the femoral head. Conclusion:The San Diego osteotomy significantly enhances hip joint range of motion and results in satisfactory hip joint function in children with developmental dysplasia of the hip

Pelvic floor muscle training (PFMT) is the first-line intervention for non-surgical treatment of female patients with stress urinary incontinence (SUI). However, due to the particularity of the physiological position of the pelvic floor muscles, 13% to 53% of patients are unable to perform PFMT correctly after the initial visit. In view of this, scholars at China and abroad put forward some other sports rehabilitation methods and achieve good clinical results. In this paper, exercise rehabilitation methods for female SUI patients were reviewed, including PFMT, core muscle training, Pilates, yoga, physical activities, etc., in order to provide reference for medical personnel to formulate scientific and feasible exercise rehabilitation programs for female SUI patients.

Objective:To investigate the short-term efficacy of rotational femoral neck osteotomy with preservation of the round ligament in the treatment of subchondral insufficiency fracture of the femoral head (SIFFH) in young and middle-aged people.Methods:A retrospective case series study was used to analyze the clinical data of 13 patients with SIFFH, who were admitted to 920th Hospital of Joint Logistics Support Force from January 2017 to January 2022. The patients included 10 males and 3 females, aged 22-49 years [(33.5±8.3)years]. There were 6 patients with fracture on the left hip and 7 on the right hip. All the patients were treated by rotational femoral neck osteotomy with preservation of the round ligament. Postoperatively, standardized joint functional training was given. The operative time and intraoperative bleeding were recorded. The modified Harris hip score and visual analogue score (VAS) were compared preoperatively, at 3, 6 months postoperatively and at the final follow-up. Radiological examinations were used to observe the occurrence of any collapse of the femoral head, non-union at osteotomy site or other complications.Results:The patients were followed up for 13-24 months [(17.9±3.1)months]. The operative time was (127.3±9.8)minutes, with the intraoperative bleeding of (393.9±21.9)ml. The values of modified Harris hip score were (61.6±3.3)points, (80.2±4.4)points, and (91.9±4.1)points at 3, 6 months postoperatively and at the final follow-up, respectively, being significantly higher than the preoperative (51.4±3.5)points (all P<0.05), and there were significant differences between different postoperative timepoints (all P<0.05). The values of VAS were (4.9±1.1)points, (3.0±0.9)points, and (1.4±0.5)points at 3, 6 months postoperatively and at the final follow-up, respectively, being significantly lower than preoperative (6.7±0.9)points (all P<0.05), and there were significant differences between different postoperative timepoints (all P<0.05). Imaging examination showed no femoral head collapse, with all the bones healed at the osteotomy site. There were no serious complications such as bone non-union, incision infection or peripheral nerve injury. Conclusion:Rotational femoral neck osteotomy with preservation of the round ligament in treating SIFFH in the young and middle-aged population has the advantages of shortened operative time, less intraoperative bleeding, promoted hip function recovery, attenuated pain and decreased complications, showing a satisfactory early effect.

Objective:To explore and optimize the management process of bladder irrigation for patients after greenlight photoselective vaporization (PVP) , reduce the occurrence of postoperative complications, and improve the satisfaction of patients and nurses for bladder irrigation.Methods:Totally 315 patients undergoing PVP in the Department of Urinary Surgery, the Second Hospital of Hebei Medical University from May 2017 to April 2019 were selected using purposive sampling. A total of 153 patients admitted from May 2017 to April 2018 were divided into the control group, who received routine bladder irrigation management, while 162 patients admitted from May 2018 to April 2019 were divided into the observation group, who received bladder irrigation management by the failure mode and effect analysis. The incidence of complications such as bladder spasm and urinary tract obstruction, the duration of continuous bladder irrigation, and patient satisfaction were compared between the two groups, and the nurse satisfaction before and after the process optimization was compared.Results:After the process optimization, the incidence of bladder spasm decreased from 17.0% (26/153) to 8.0% (13/162) , the incidence of urinary tract obstruction decreased from 11.8% (18/153) to 3.7% (6/162) , and the differences were statistically significant (χ 2=5.835, 7.264; P<0.05) . The duration of bladder irrigation was shortened from (25.311±2.295) h to (22.422±1.481) h, and the difference was statistically significant ( t=13.348, P<0.05) . After optimizing the bladder irrigation management process, the nurse satisfaction score was (34.221±5.124) , and the patient satisfaction score was (37.113±6.108) , both higher than those before the optimization, and the differences were statistically significant ( t=19.817, 14.546; P<0.05) . Conclusions:Optimizing the bladder irrigation management process for patients after PVP using the failure mode and effect analysis can reduce the incidence of postoperative bladder irrigation complications, shorten the duration of bladder irrigation, and improve patient and nurse satisfaction.
