With the popularization of 5G communication technology and the continuous upgrade of robot-assisted surgery system,telesurgery has developed rapidly.However,there are few of reports about this technique in single-port laparoscopic gynecological surgery.On April 19,2024,the surgeons at the Second Affiliated Hospital of Naval Medical University in Shanghai successfully implemented robot-assisted single-port laparoscopic bilateral adnexectomy for a patient who was admitted to the Naval Hospital of the Eastern Theater Command in Zhoushan,Zhejiang Province through 5G communication technology.The operation time was 90 min,intraoperative bleeding was 20 ml,and no intraoperative complications occurred.There were no adverse events caused by robots such as robot system failure and instrument failure,or adverse events caused by remote communication such as network interruption and network attack.Intraoperative user datagram protocol(UDP)real-time monitoring data showed an average delay of 108 ms(range,105-111 ms)and a packet loss rate of 0.04%.The surgeons had a slight sense of delay when the operation amplitude was too large.There was no obvious stalling which affected the process of the operation.The patient was able to move around on the first day after surgery,and the catheter was removed.No postoperative complications occurred.The patient was discharged from the hospital on the second day after surgery.Postoperative pathological results revealed left fallopian tube ovarian serous cystadenofibroma,fallopian tubal tissue;right fallopian tube ovarian,sent for examination as ovarian and fallopian tube tissue.There were no complaints of discomfort during reexamination one month after surgery,and the umbilical incision healed well.This case is an attempt of telesurgery in the field of gynecology,and provides experiences for the further development of this technique.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To systematically retrieve,evaluate and integrate evidences about the assessment and management of perioperative pain in patients with acute aortic dissection.Methods PIPOST model was used to identify themes of assessment and management of perioperative pain.The literatures in the themes was systematically searched through the databases of UpToDate,JBI,BMJ Best Practice,practice guide REgistration for trans RAREncy(PREPARE),Guidelines International Network(GIN),National Guideline Clearinghouse(NGC),National Institute for Health and Care Excellence(NICE),Scottish Intercollegiate Guidelines Network(SIGN),New Zealand Guidelines Group(NZGG),Registered Nurses'Association of Ontario(RNAO),Australian Clinical Practice Guidelines(ACPG),American Heart Association(AHA),European Society of Cardiology(ESC),the Chinese Cochrane Center,Medlive,Cochrane library,PubMed,SinoMed,CNKI,Wangfan Data,and VIP.The retrieved literatures were evaluated and the evidences that met the inclusive criteria were extracted from the literatures by researchers who had trained for evidence-based study.Results A total of 17 studies,including 5 guidelines,3 expert consensus,6 systematic reviews and 3 randomised controlled trials were included in this study.Totally,29 pieces of best evidence were extracted in the assessment and management of pain in perioperative patients with acute aortic dissection,including pain assessment,basic principles of pain management,medication intervention strategies of pain management,non-medication intervention strategies of pain management,pain evaluation,education of pain management and organising pain management.Conclusion Evidences in assessment and management of pain in perioperative patients with acute aortic dissection can provide references and guidance for clinical practice.

Objective:To compare the therapeutic effects of cannulated screws and Kirschner wires in the treatment of medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ in children.Methods:A retrospective study was conducted to analyze the data of 48 and 16 children who had been treated respectively at Department of Pediatric Orthopaedics, Fuzhou Second General Hospital, and Department of Pediatric Orthopaedics, Foshan Hospital of Traditional Chinese Medicine for medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ from June 2016 to June 2022. There were 32 males and 32 females with an age of 12 (10, 14) years; 31 left and 33 right sides were affected. By the Salter-Harris classification: type Ⅲ in 45 cases, and type Ⅳ in 19 cases. The patients were divided into 2 groups according to their internal fixation methods. Group A (44 cases) was subjected to internal fixation with cannulated screws and group B (20 cases) to internal fixation with Kirschner wires. At the last follow-up, anteroposterior and lateral X-ray films of their ankle joints were taken for imaging evaluation. Functional recovery of the affected limbs was evaluated based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring, and related complications were recorded.Results:The 2 groups were comparable because there were no significant differences in their preoperative general data except laterality ( P>0.05). All the patients were followed up for (37.3±21.5) months and achieved bony union. At the last follow-up, for groups A and B respectively, the distal lateral angle of the tibia was 89.0° (89.0°, 90.0°) and 89.0° (89.0°, 90.0°), the range of ankle motion was 73.5° (67.8°, 76.0°) and 70.0° (70.0°, 75.0°), and the good and excellent rate by the AOFAS ankle-hindfoot scoring was 97.7% (43/44) and 95.0% (19/20), showing no significant difference between the 2 groups ( P>0.05). There was a significant difference between the 2 groups in the incidence of premature physeal closure [36.4% (16/44) versus 65.0% (13/20)] ( P=0.033). Conclusions:In the treatment of medial malleolar fractures of Salter-Harris types Ⅲ and Ⅳ in children, internal fixation with both cannulated screws and Kirschner wires can lead to comparable efficacy in good functional recovery and imaging evaluation. However, fixation with cannulated screws may be more advantageous in reducing the risk of early closure of the epiphysis.

Objective:To explore the clinical features and surgical outcomes of greater trochanteric fractures of the femoral neck in children.Methods:A retrospective study was conducted to analyze the 5 children with greater trochanteric fracture of the femoral neck who had been treated at Department of Pediatric Orthopaedics, Fuzhou Second General Hospital from January 2011 to December 2020. There were 1 boy and 4 girls, with an age of (11.0±1.9) years. By the Delbet classification, all were type Ⅲ fractures. The time from injury to operation was (4.4±2.1) days. The children were treated with cannulated screws (1 case) or fixation with a pediatric hip plate (4 cases). The clinical features of such fractures were analyzed; the fracture union time and hip function and complications at the last follow-up were recorded.Results:The clinical features of greater trochanteric fractures of the femoral neck in children were: (1) involvement of 2 anatomic sites in a narrow region, (2) comminuted fractures, and (3) all Delbet type Ⅲ fractures. The follow-up time was (22.8±6.0) months. All the 5 children obtained bony union. The union time was (5.2±1.8) weeks for greater trochanteric fractures, and 8.0 (8.0,10.0) weeks for femoral neck fractures. Follow-up observed no necrosis of the femoral head, premature closure of the femoral head epiphysis, hip varus deformity, or length disparity between the lower limbs. Premature closure of the greater trochanteric epiphysis occurred in 2 children after surgery. According to the Ratliff scoring, the hip function was excellent in 3 cases and good in 2.Conclusions:Greater trochanteric fractures of the femoral neck in children are a special kind of proximal femoral comminuted fractures that affect 2 anatomic sites in a narrow region and belong all to Delbet type Ⅲ fractures. Open reduction and internal fixation with cannulated screws or a pediatric hip plate is a safe and effective treatment for such fractures.

Objective:To study lncRNA MEG3 expression and its relationship with Th17/CD4+T cells in patients with non-small cell lung cancer(NSCLC)with different pleural effusion severity and prognosis.Methods:A total of 104 NSCLC malignant pleural effusion patients admitted to Quanzhou First Hospital Affiliated to Fujian Medical University from January 2020 to December 2022 were selected as research subjects,and divided into three groups based on amount of pleural effusion,including small amount of pleural effusion group(35 cases),moderate amount of pleural effusion group(42 cases)and large amount of pleural effusion group(27 cases).According to actual development and prognosis of patient's disease,they were divided into good prognosis group(29 cases without recurrence and metastasis)and poor prognosis group(75 cases with recurrence and metastasis).Another 60 patients with benign pleural effusion due to pneumonia who were treated in Quanzhou First Hospital Affiliated to Fujian Medical University at same time were selected as control group.MEG3 expression in pleural effusion of two groups was detected by real-time fluorescent quantita-tive PCR,and peripheral venous blood of subjects was collected.Th17 cell and CD4+T cell ratios of peripheral blood were detected by flow cytometry,and Th17/CD4+T was calculated.lncRNA MEG3 and peripheral blood Th17 and CD4+T levels in each group of patients compared.Logistic regression analysis was used to analyze pleural effusion and prognostic factors in NSCLC.Results:lncRNA MEG3 expression and CD4+T percentage in pleural effusion in NSCLC group were lower than control group,while Th17 percentage and Th17/CD4+T were higher than control group(P<0.05).lncRNA MEG3 expression and CD4+T percentage in large pleural effusion group were lower than small and moderate pleural effusion groups.lncRNA MEG3 expression and CD4+T percentage in modarate pleural effusion group were lower than small pleural effusion group,while Th17 percentage and Th17/CD4+T in large pleural effusion group were higher than small and moderate pleural effusion groups.Th17/CD4+T was higher in small amount pleural effusion group(P<0.05).lncRNA MEG3 expression and CD4+T percentage in poor prognosis group were lower than those in good prognosis group,while Th17 percentage and Th17/CD4+T were higher than good prognosis group(P<0.05).Logistic regression analysis showed that lncRNA MEG3 was a protective factor for NSCLC pleural effusion,and Th17/CD4+T was a risk factor(P<0.05),lncRNA MEG3 was a protective factor of NSCLC prognosis,and Th17/CD4+T was a risk factor(P<0.05).Conclusion:lncRNA MEG3 expression and Th17/CD4+T in NSCLC patients with different pleural effusion severity and prognosis is not same.lncRNA MEG3 is a risk factor for NSCLC pleural effusion and prognosis,while Th17/CD4+T is a risk factor,which can be used as an effective biomarker for pleural effusion severity and progno-sis diagnosis.

Objective:To evaluate the safety and feasibility of the laparoscopic indocyanine green (ICG) fluorescence imaging during the sentinel node navigational surgery for the early gastric cancer.Methods:Patients with <4 cm early gastric cancer were chosen. 0.5 ml ICG (2.5 mg/ml) was preoperatively injected into submucosa around the lesion in four points by the endoscopy. The sentinel lymph node basin including the stained tissue and lymph node (LN) were completely resected guided by the fluorescence mapping under ICG laparoscopy. The specimen was inspected by frozen pathology section. The radical gastrectomy was dependent on the pathology result.Result:Between 2019 and 2021, a total of 18 patients were included in the final analysis. Most tumors (16/18) located in the middle or distal stomach. Median tumor size was 2.0 cm. Lymph vessel invasion was revealed in five cases and perineural invasion in three cases. According to AJCC tumor grading system, tumor depth was classified as Tis in 2 cases, T1a in 5 cases and T1b in 11 cases. Lymph node metastasis (LNM) was revealed in four patients (4/18, 22%). Median sentinel lymph node basins per patient were 2 (range, 1-5). An average 6 (range, 2-13) LNs were harvested in each case, including 6 (1-13) ICG stained LNs and 1 (0-5) non stained LNs. All of four LNM patients were detected by sentinel node navigational surgery. The rate of the sensitivity and accuracy were 100% and 100%, respectively. The median follow-up for the entire group was 58.3 months (0.3-59.9 months), with no recurrence or metastasis observed in any patient.Conclusion:The sensitivity and accuracy of the laparoscopic indocyanine green fluorescence imaging during the sentinel node navigational surgery were satisfactory.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.
