Objective To evaluate the clinical efficacy of anterior versus posterior surgical approaches in the treatment of thoracic spinal tuberculous kyphosis.Methods From January 2018 to January 2023,a total of 67 patients with thoracic spinal tuberculous kyphosis were treated.According to the surgical approach,patients were divided into an anterior group(30 cases)and a posterior group(37 cases).The operation time,blood loss,Cobb Angle before the operation,6 months after the operation,and at the last follow-up(12 months after the operation),visual analog scale(VAS)score,and oswestry disability index(ODI)were compared between the two groups.Results The anterior group had significantly longer operative time and greater intraoperative blood loss compared to the posterior group(P＜0.05).At 6 months post operatively,the Cobb angle in the anterior group was significantly lower than that in the posterior group(P＜0.05).Subgroup analysis showed no significant differences between the anterior and posterior groups in preoperative,6 months,and 12 months Cobb angles,correction degree,correction loss for single-segment cases(P＞0.05).However,in multi-segment cases,the anterior group had significantly higher Cobb angles at both preoperative and 6-month postoperative time points compared to the posterior group(P＜0.05),while no significant differences were observed at 12 months,including in correction degree and loss(P＞0.05).The VAS score and ODI of the anterior approach group and the posterior approach group at 6 months after surgery were lower than those before surgery,and the VAS score and ODI at 12 months after surgery were lower than those at 6 months after surgery.The differences were statistically significant(P＜0.05).During the follow-up period,no recurrence of tuberculosis,failure of internal fixation or significant loss of correction was observed.Conclusion Both anterior and posterior surgical approaches can effectively treat single-segment tuberculous thoracic kyphosis,with comparable efficacy.The anterior approach is more suitable for patients with localized lesions requiring anterior decompression,whereas the posterior approach offers advantages in deformity correction and spinal stability reconstruction,especially in cases involving multi-segmental lesions.

Objective:To investigate lymph node metastasis(LNM)in the prostatic anterior fat pad(PAFP)of PCa patients after robot-assisted radical prostatectomy(RARP),and analyze the clinicopathological features and prognosis of LNM in the PAFP.Methods:We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urolo-gy of PLA General Hospital from January 2017 to December 2022.All the patients underwent routine removal of the PAFP during RARP and pathological examination,with the results of all the specimens examined and reported by pathologists.Based on the pres-ence and locations of LNM,we grouped the patients for statistical analysis,compared the clinicopathological features between different groups using the Student's t,Mann-Whitney U and Chi-square tests,and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio.Results:Lymph nodes were detected in 77(7.7％)of the 1 003 PAFP samples,and LNM in 11(14.3％)of the 77 cases,with a positive rate of 1.1％(11/1 003).Of the 11 positive cases,9 were found in the upgraded pathological N stage,and the other 2 complicated by pelvic LNM.The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group(81.8％[9/11]vs 36.2％[359/992],P=0.005),and so did the cases with Gleason score ≥8(87.5％[7/8]vs 35.5％[279/786],P=0.009).No statisti-cally significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the pa-tients with PAFP LNM only and those with pelvic LNM only.Conclusion:The PAFP is a potential route to LNM,and patients with LNM in the PAFP are characterized by poor pathological features.There is no statistically significant difference in biochemical recur-rence-free survival between the patients with PAFP LNM only and those with pelvic LNM only.Routine removal of the PAFP and inde-pendent pathological examination of the specimen during RARP is of great clinical significance.

Objective:To evaluate the efficacy of purified donor CD34 positive hematopoietic stem cell (CD34 + cell) infusion in patients with poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods:The clinical data of 25 patients with PGF who underwent donor CD34 + cell sorting and infusion at the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences between September 2019 and March 2023, were retrospectively analyzed. The cohort included 19 haploidentical and 6 HLA-matched cases. CD34 + cells were purified using immunomagnetic beads for therapeutic infusion. The purification efficiency was evaluated based on the purity and recovery rate of CD34 + cells. Clinical outcomes were assessed by hematopoietic recovery, overall survival (OS) rate, and the incidence of graft-versus-host disease (GVHD) . Results:The median total number of CD34 + cells was 2.64 (0.82-6.53) × 10 8 before purification and 2.22 (0.48-5.68) ×10 8 after purification, with a median recovery rate of 78.37% (58.48%-115.72%) . After infusion of purified CD34 + cells, 8 of 10 patients (80.0%) with poor neutrophil engraftment achieved recovery (absolute neutrophil count ≥ 0.5×10 9/L) , with a median time to recovery of 21 (10-40) days. And 15 of 21 patients (71.4%) with poor platelet engraftment achieved recovery (platelet count ≥ 20×10 9/L) , with a median time to recovery of 15 (13-38) days. Only 3 patients (12.0%) developed GVHD after the infusion of purified CD34 + cells, including 2 cases of grade I acute GVHD and 1 case of limited chronic GVHD. With a median follow-up of 14.47 (0.23-41.63) months, the overall OS rate after CD34 + cell infusion was (65.63± 8.28) %. Seventeen patients survived, with a median survival time of 19.07 (0.23-41.63) months. Conclusion:Purification of CD34 + cells using immunomagnetic beads is effective, and the infusion of these purified donor CD34 + cells can safely and effectively improve PGF after allo-HSCT.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To evaluate the early efficacy and safety of transnasal endoscopic surgical resection of orbital cavernous hemangioma (OCH) at orbital resection by intranasal technique (ORBIT) stage Ⅲ.Methods:A retrospective study was conducted on 20 patients (20 eyes) who underwent nasal endoscopic surgery to remove ORBIT stage Ⅲ OCH at the Third Hospital of Peking University from July 2021 to July 2024. The cohort were included 10 males and 10 females, aged from 25 to 59 years, with a mean follow-up time of (5.10±4.51) months. Preoperative symptoms included visual field defects in 19 patients (95%), decreased visual acuity in 18 patients (90%), exophthalmos in 2 patients (10%), diplopia in 2 patients (10%), headache in 2 patients (10%), ocular pain in 2 patients (10%), and color vision abnormalities in 1 patient (5%). Data on patient demographics, medical history, imaging data, surgical approach, and postoperative outcomes were collected. Pre-and post-surgical outcomes including best corrected visual acuity (BCVA), visual field, proptosis, and intraocular pressure were compared. Surgical approaches included transnasal endoscopic OCH resection (12 cases, 60%) and transnasal endoscopic combined conjunctival approach OCH resection (8 cases, 40%). The results of the postoperative 2-week review were used as the postoperative short-term efficacy data, and those at 3 months were used for postoperative therapeutic efficacy analysis. SPSS 26.0 statistical software was applied for statistical analysis.Results:In 20 patients, all OCH were completely resected, and the BCVA, visual field, and exophthalmos were significantly improved post-operatively. The differences were statistically significant before and after surgery ( t values were 3.169, 5.127, and 3.350, respectively, all P<0.05). There were no serious complications in the short term after surgery. The short-term complications after endoscopic surgery alone were mainly new-onset diplopia in 1 case (1/12), and the short-term complications after combined approach were new-onset diplopia in 5 cases (5/8) and pupil dilation in 2 cases (2/8). All short-term complications recovered within 3 months, and no serious or permanent complications occurred in the long-term follow. Conclusion:The endoscopic transnasal surgery is a safe and effective approach for complete resection of ORBIT stage Ⅲ OCH, with promising early results.

Objective:To establish and assess the quality control and improvement system for metabolic and bariatric surgery in Beijing.Methods:Based on relevant documents from the National Health Commission and the Beijing Municipal Health Commission,and referencing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) by the American Society for Metabolic and Bariatric Surgery,a quality control system was developed under the Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery. The system incorporated on-site evaluations,data registration,and specialized training. From May to December 2023,on-site assessments were conducted at 21 hospitals in Beijing performing bariatric surgery,evaluating personnel qualifications,infrastructure,clinical workflows,and postoperative follow-up. A quality control database was created to collect real-time surgical data,and training was provided for data entry and professional skills. Assessment results were classified as excellent,qualified,or needing improvement,with rectification suggestions offered and follow-up visits conducted to track progress.Results:All 21 hospitals achieved a 100% compliance rate for surgical indications, 16 (76.2%) met standardized surgical operation criteria,and 14 (66.7%) had standardized postoperative management. However,only 5 (23.8%) achieved a 12-month postoperative follow-up rate of ≥60%,and 4 (19.1%) had established specialized databases. Key challenges included insufficient specialized staffing (19.1%), lack of multidisciplinary collaboration (47.6%), inadequate equipment (57.1%), and low follow-up rates (57.1%). The database collected data from over 2 000 patients across 111 fields. After rectification, specialized database coverage rose to 61.9% (13 hospitals). Multi-level training programs developed backbone physicians and specialized nurses,significantly addressing the shortage of specialized personnel.Conclusion:The quality control system established in this study,through the integration of on-site evaluation,data registration,and specialized training,effectively enhances the standardization of surgical practices and data management capabilities.
