This paper reviews the published articles of recent years on the application of deep learning methods in automatic localization of acupoint, and summarizes it from 3 key links, i.e. the dataset construction, the neural network model design, and the accuracy evaluation of acupoint localization. The significant progress has been obtained in the field of deep learning for acupoint localization, but the scale of acupoint detection needs to be expanded and the precision, the generalization ability, and the real-time performance of the model be advanced. The future research should focus on the support of standardized datasets, and the integration of 3D modeling and multimodal data fusion, so as to increase the accuracy and strengthen the personalization of acupoint localization.

Pyroptosis is a form of programmed cell death that differs from classical apoptosis and passive necrosis.It plays a crucial role in activating innate immune responses,driving local inflam-matory reactions,regulating immune cell activation and infiltration,and remodeling the tumor immune microenvironment.In recent years,the role of pyroptosis in the initiation,progression,and treatment response of urological tumors has garnered increasing attention.Current studies have demonstrated that pyroptosis exhibits dual regulatory effects in various tumors:on the one hand,it exerts anti-tumor effects by inducing lytic death of tumor cells;on the other hand,under specific microenvironmental conditions,the chronic inflammatory response mediated by pyroptosis may promote immune escape,thereby driving tumor progression.This review systematically summarized the similarities and differ-ences in the molecular mechanisms of pyroptosis in three common urological tumors,namely renal cell carcinoma,bladder cancer,and prostate cancer.It also summarized the regulatory networks and po-tential therapeutic targets during tumor initiation and progression.Furthermore,it elucidated the re-search progress on enhancing the efficacy of immune checkpoint inhibitors by modulating pyroptosis pathways,aiming to provide novel strategies and theoretical foundations for the precise treatment of u-rological.

Objective To compare the efficacy and safety of computed tomography (CT)-guided percutaneous versus electromagnetic navigation bronchoscopy (ENB)-guided microwave ablation (MWA) for the treatment of pulmonary nodules. Methods A retrospective analysis was conducted on the data of high-risk pulmonary nodule patients who underwent MWA at the Nanjing Drum Tower Hospital between 2022 and 2023. The pathological diagnosis rate, complications, and progression-free survival (PFS) rate were compared between the CT group and the ENB group. Results There were 61 patients in the CT group, including 30 males and 31 females, with an average age of (67.22±9.13) years. There were 53 patients in the ENB group, including 29 males and 24 females, with an average age of (65.29±13.76) years. The pathological diagnosis rate in the CT group was slightly higher than that in the ENB group (88.52% vs. 71.69%, P=0.03). However, the ENB group exhibited a lower incidence of perioperative complications, including pneumothorax (16.39% vs. 3.77%, P=0.03), hemoptysis (19.67% vs. 5.66%, P=0.05), and pain (22.95% vs. 7.55%, P=0.03). There was no statistically significant difference in PFS rate between the two groups [HR=1.17, 95%CI (0.23, 5.81), P=0.85]. Conclusion Both CT-guided and ENB-guided MWA are effective treatment modalities for high-risk pulmonary nodules.

Objective:To evaluate the efficacy and safety of sintilimab combined with bevacizumab in the second-line treatment of malignant pleural mesothelioma(MPM).Methods:This was a longitudinal study. Patients with MPM who had progressed after first-line treatment and were admitted to the Day-Care Outpatient Department of Medical Oncology, Ningguo People′s Hospital from February 2019 to February 2022 were included. General clinical data of the patients were collected at baseline. The patients were treated with the second-line treatment regimen of sintilimab (200 mg)+bevacizumab (15 mg/kg) on a 21-day cycle. Enhanced CT scans were performed every 3 cycles to evaluate the efficacy until tumor progression or death. Follow-up period ended in December 2023. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Efficacy was evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST), and the best response of each patient was recorded. The objective response rate (ORR) and disease control rate (DCR) were calculated. Adverse reactions were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), ranging from grade Ⅰto Ⅳ. Kaplan-Meier survival curves were used to analyze PFS and OS, and survival times were expressed as median values.Results:A total of 23 MPM patients were included, with the mean age of (55.04±13.27)years, 15 males, 8 females, 19 cases of epithelial type and 4 cases of non-epithelial type. The Eastern Cooperative Oncology Group (ECOG) performance status scores were 0-1 in 12 patients and 2 in 11 patients. There were 17 smokers and 6 non-smokers, 12 cases with PD-L1 positive and 11 cases with PD-L1 negative, and 6 cases with anti-angiogenic drugs and 17 cases without using anti-angiogenic drugs in the first-line treatment. Of the 23 patients, 1 achieved complete response (CR), 9 achieved partial response (PR), 7 had stable disease (SD), and 6 had progressive disease (PD). The ORR and DCR of the enrolled patients were 43.5% (10/23) and 73.9% (17/23), respectively. Kaplan-Meier survival analysis showed that the PFS of the enrolled patients was 7.50 (95% CI: 5.47-9.54) months, and the OS was 12.50 (95% CI: 1.07-23.93) months. The most common adverse reactions related to the treatment of sintilimab combined with bevacizumab were hypertension (14 cases (60.9%)), fatigue (10 cases (43.5%)), decreased appetite (8 cases (34.8%)), proteinuria (6 cases (26.1%)), pruritus (5 cases (21.7%)), constipation (4 cases (17.4%)) and nausea (3 cases (13.0%)), etc. Only 9 patients had grade Ⅲ adverse reactions (8 cases of hypertension and 1 case of nausea), and only 1 patient had grade Ⅳ adverse reaction (hypertension). Conclusion:Sintilimab combined with bevacizumab has some therapeutic effects on progressive MPM, and the adverse reactions are relatively mild.

Objective To compare the short-term clinical effects of unilateral dual-channel endoscopic discectomy(UBED)and percutaneous endoscopic intervertebral discectomy(PEID)in the treatment of L5S,Lumbar disc herniation,LDH.Methods From January 2019 to January 2021,a total of 57 cases of L5S,LDH treated by UBED or PEID were analyzed retrospectively,including 30 cases in UBED group and 27 cases in PEID group.The operation time,intraoperative fluoroscopy times,postoperative hospitalization days and surgical complications were compared between the two groups.The visual analogue scale(VAS)and oswestry disability index(ODI)were used to compare the postoperative quality of life of the two groups,and the modified MacNab criteria was used to evaluate the clinical efficacy in the last follow-up.Results The operation time of UBED group and PEID group was(75.30±8.44)minutes and(68.37±4.63)minutes,respectively,and the difference between the two groups was statistically significant(P＜0.05).VAS and ODI of 1 week,3 months,1 year and 1.5 years after surgery in 2 groups were significantly decreased compared with those before surgery,with statistical significance(P＜0.05).The VAS score of low back pain in UBED group was higher than that in PEID group[(3.87±1.14)points vs(2.70±0.67)points]at 1 week after surgery(P＜0.05),and there was no significant difference in VAS and ODI at the other time points(P＞0.05).There was no statistical difference in the results of modified MacNab criteria in the last follow-up(P＞0.05).There were 2 cases of dural tear in PEID group,1 case of dural tear in UBED group and 1 case of temporary nerve root injury in PEID group after operation,all of which were cured after symptomatic treatment.Conclusion Compared with PEID,UBED has a longer operation time,more trauma and more obvious low back pain in the short term after operation.The short-term curative effect of the two operations on L5S1 LDH is similar,the incidence of complications is low,and the times of fluoroscopy are few.Both operations are safe and effective.

Objective:To characterize the biomechanics of distal dynamic locking and distal static locking of proximal femur bionic nails (PFBN) in fixation of intertrochanteric fractures by a finite element analysis.Methods:The CT image data from the hip to the upper tibia from an adult male volunteer were used to establish a three-dimensional model of the femur by Mimics 20.0 and Geomagic 2013 which was processed further into a model of Evans type I intertrochanteric fracture by software NX 12.0. With reference to the internal fixation parameters commonly used, 4 models of PFBN fixation were established: distal single transverse nail dynamic locking (model A), single oblique nail dynamic locking (model B), single nail static locking (model C) and double nail dynamic locking (model D). Abaqus 6.14 software was used to load and analyze the internal fixation stresses and displacements of fracture ends.Results:Under a 2100N loading, the peak stress was located upon the main nail in the 4 models. The smallest peak stress upon the main nail was in Model D (161.9 MPa), decreased by 15.9% compared with model A (192.5 MPa), by 15.6% compared with model B (191.9 MPa), and by 0.9% compared with model C (163.3 MPa). The peak stress upon the fixation screw was the largest in model A (95.3 MPa), the smallest in model B (91.5 MPa), and 91.5 MPa and 92.2 MPa in models C and D, respectively. The overall displacements of the implants, in a descending order, were 10.14 mm in model A, 10.10 mm in model B, 10.09 mm in model C, and 10.05 mm in model D. Similarly, the displacements of fracture ends were 0.125 mm in model A, 0.121 mm in model B, 0.110 mm in model C, and 0.098 mm in model D.Conclusion:Compared with dynamic locking, distal static locking of PFBN provides a better mechanical stability and reduces stress concentration upon internal fixation.
