Objective: To investigate the clinical efficacy and safety of pudendal nerve modulation (PNM) in the treatment of female pudendal neuralgia (PN)，so as to promote the clinical application of this technique. Methods: A retrospective analysis was conducted on 20 female PN patients who failed conservative treatment at Gongli Hospital during Nov.2020 and Oct.2023.All patients underwent simultaneous PNM and sacral nerve modulation (SNM) with the assistance of 3D printing navigation.Dual-stage test electrodes for PNM and SNM were implanted，followed by alternate therapeutic trial for each modality.Secondary conversion rates and longitudinal outcomes，including visual analogue score (VAS)，patient health questionnaire-9 (PHQ-9)，and quality of life (QoL) scores were compared preoperatively，post-stage Ⅰ，and at 3，6，and 12 months post-stage Ⅱ. Results: All operations were successful.After the trial phase，the secondary conversion rate for PNM was significantly higher than that for SNM; 16 patients (16/20，80%) chose the second-phase PNM implantation surgery，3 (3/20，15%) chose second-phase SNM implantation，and 1 (1/20，5%) had electrodes removed due to ineffective results from both trials.Further assessment revealed that the improvements in VAS，PHQ-9，and QoL scores for PNM patients were significantly better than those for SNM patients after the first phase of surgery and at 3，6 and 12 months after the second-phase conversion (P<0.05).No complications such as electrode migration or infection were observed during the follow-up of 12-15 months. Conclusion: PNM provides more effective relief of pain symptoms and improvements in depressive states for female PN patients compared to SNM.With the assistance of 3D printing navigation，the operation is simple and safe，and offers stable therapeutic effects.It is worthy of clinical promotion and application.

Objective To explore the short-term efficacy of endoscopic submucosal dissection (ESD) in the treatment of early carcinoma in the remnant stomach. Methods A retrospective study was conducted on 45 patients with early residual gastric cancer underwent ESD at the Endoscopy Center of Zhongshan Hospital, Fudan University from December 2014 to April 2024, with a total of 45 lesions. The patients were divided into an anastomotic group (n=15) and a non-anastomotic group (n=30) based on the location of tumor occurrence, and their clinical data, endoscopic diagnosis and treatment, and histopathological conditions were compared between the two groups. Results All 45 patients had lesions with redness and erosion. There were 9 cases of poor lifting of submucosal injection in the anastomotic group and 2 cases in the non-anastomotic group, respectively, and the difference was statistically significant (P<0.05). ESD surgery was performed on 13 lesions in the anastomotic group and 28 lesions in the non-anastomotic group, with surgery times of 80.00 (50.00, 100.00) min and 55.00 (43.75, 80.00) min, respectively. The difference in surgery time between the two groups was statistically significant (P=0.03). Among the 45 patients, ESD surgery achieved curative resection in 35 cases, including 11 cases in the anastomotic group and 24 cases in the non-anastomotic group, with no statistically significant difference. Conclusions Careful preoperative evaluation of early carcinoma in the remnant stomach is essential to prevent oversight. Lesions at anastomotic sites and suture lines present higher technical challenges for complete resection. ESD is safe and effective, with auxiliary traction technique available when necessary.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective To discuss the causes and the therapeutic strategy of acute cardiac tamponade(ACT)occurring as a complication of transcatheter aortic valve replacement(TAVR)so as to improve the success rate of the surgery and to make a further understanding of this complication.Methods The general clinical data,surgical procedures,and postoperative follow-up results of five patients,who received TAVR at the Affiliated Northern Jiangsu People's Hospital of Yangzhou University of China and developed ACT from March 2018 to September 2024,were retrospectively analyzed.Results After developing ACT,all the 5 patients received pericardiocentesis together with other adjuvant therapies including blood volume expansion with infusion,vasopressors,heparin neutralization,and blood transfusion.However,due to no obvious reduction in drainage volume and unstable hemodynamics all the 5 patients had eventually to receive open-chest surgery to identify the source of bleeding and to make hemostasis.Surgical exploration revealed that the perforation or rupture of cardiac structures caused by the temporary pacemaker lead or a super-stiff guide wire during the procedure was the main cause of ACT.Finally,after active treatment four patients recovered and discharged,and one patient died.The discharged patients were followed up for 3-12 months,and no procedure-related complications such as acute coronary artery occlusion,severe arrhythmia,exacerbation of heart failure symptoms,valve displacement,or stroke occurred.Conclusion As a severe complication occurring during the TAVR procedure,ACT requires to get a rapid diagnosis and management.Improvement of surgical techniques and operative methods,comprehensive preoperative assessment,and close intraoperative monitoring are crucial points for the prevention of ACT.

ObjectiveTo explore the effect of core muscles training based on spinal fine-tuning manipulation on lumbar facet joint disorders. MethodsFrom February, 2021 to February, 2022, 80 patients with lumbar facet joint disorders in Huadong Hospital Affiliated to Fudan University were randomly divided into control group (n = 40) and observation group (n = 40) randomly. Both groups received routine treatment and spinal fine-tuning manipulation, while the observation group received core muscles training in addition, for six weeks. They were assessed with Japanese Orthopaedic Association (JOA) scores, Short-Form of McGill Pain Questionnaire and World Health Organization Quality of Life-BREF before and after treatment. The recurrence rate was observed after three months follow-up. ResultsThe scores of all the scales improved after treatment (t > 5.751, P < 0.001), and improved more in the observation group than in the control group (t > 2.051, P < 0.05). After three months follow-up, the recurrence rate was 7.89% (3/38) in the observation group, less than 28.13% (9/32) in the control group (χ² = 5.005, P = 0.025). ConclusionCombination of core muscles training may improve lumbar function, reduce lumbar pain, reduce recurrence and improve quality of life for patients with lumbar facet joint disorders.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective To investigate the effect of Jisuikang formula-medicated serum for promoting spinal cord injury (SCI) repair in rats and explore the possible mechanism. Methods Thirty adult SD rats were randomized into sham-operated group, SCI (induced using a modified Allen method) model group, and Jisuikang formula-medicated serum treatment group. After the operations, the rats were treated with normal saline or Jisuikang by gavage on a daily basis for 14 days, and the changes in hindlimb motor function of the rats was assessed with Basso-Beattie-Bresnahan (BBB) scores and inclined-plate test. The injured spinal cord tissues were sampled from the SCI rat models for single-cell RNA sequencing, and bioinformatics analysis was performed to identify the target genes of Jisuikang, spinal cord injury and glycolysis. In the cell experiment, cultured astrocytes from neonatal SD rat cortex were treated with SOX2 alone or in combination with Jisuikang-medicated serum for 21 days, and the protein expressions of PKM2, p-PKM2 and YAP and colocalization of PKM2 and YAP in the cells were analyzed with Western blotting and immunofluorescence staining, respectively. Results The SCI rats with Jisuikang treatment showed significantly improved BBB scores and performance in inclined-plate test. At the injury site, high PKM2 expression was detected in various cell types. Bioinformatic analysis identified the HIPPO-YAP signaling pathway as the target pathway of Jisuikang. In cultured astrocytes, SOX2 combined with the mediated serum, as compared with SOX2 alone, significantly increased PKM2, p-PKM2 and YAP expressions and entry of phosphorylated PKM2 into the nucleus, and promoted PKM2 and YAP co-localization in the cells. Conclusion Jisuikang formula accelerates SCI repair in rats possibly by promoting aerobic glycolysis of the astrocytes via activating the PKM2/YAP axis to induce reprogramming of the astrocytes into neurons.

Objective To investigate the expression and clinical significance of mismatch repair (MMR) protein,human epidermal growth factor receptor (HER)2 and Ki-67 in colorectal cancer.Methods The clini-cal data of 559 patients with colorectal cancer who underwent surgical treatment in the hospital from October 2017 to May 2022 were retrospectively analyzed.The expressions of MMR protein (MLH1,MSH2,PMS2, MSH6),HER2 and Ki-67 in colorectal cancer were detected by immunohistochemistry,and the relationship between them and the clinicopathological features of colorectal cancer was analyzed.Results Among the 559 patients with colorectal cancer,43 cases (7.7％) were deficient mismatch repair (dMMR),8 cases(1.4％) were HER2 +++,and 251 cases (44.9％) were Ki-67 +++.The expression rate of dMMR in the colorec-tal cancer patients with different age,tumor location,tumor maximum diameter,gross type,histological grade,lymph node metastasis and TNM stage was significantly different (P<0.05).The expression rate of HER2 ++/+++ in the patients with different gross types of colorectal cancer was statistically significant (P<0.05).The expression rate of Ki-67 +++ in the colorectal cancer patients with different histological types,histological grades,lymph node metastasis,distant metastasis and TNM staging was statistically signifi-cant (P<0.05).There was no correlation between MMR protein and the expression of HER2 and Ki-67 (P>0.05).Conclusion The expression of MMR proteins in colorectal cancer is closely related to its clinicopatho-logical features.
