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 investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective To investigate the clinical efficacy of platelet-rich plasma (PRP) therapy for interstitial cystitis/bladder pain syndrome (IC/BPS). Methods This single-center prospective study involved 97 IC/BPS patients treated in our hospital during Sep.2023 and Apr.2025, who underwent transurethral bladder injection of PRP. The injections were administered once a month for four sessions. The global response assessment (GRA) score,24-hour urinary frequency, maximum single voiding volume, visual analogue scale (VAS) score, O'Leary score, pelvic pain, urgency and frequency (PUF) score, and Zung self-rating anxiety scale (SAS) score were analyzed. Results All 97 patients completed four injections. The GRA score,24-hour urinary frequency, VAS score, O'Leary score and PUF score were improved significantly after treatment (P<0.007). Intraoperative bladder capacity with significant improvement were observed after the first injection (P<0.01), and the maximum urine output were observed after the fourth injection (P<0.007). The SAS score was not significantly improved. Conclusion Repeated PRP injections can effectively alleviate bladder pain, improve frequent and urgent urination symptoms, and increase the bladder capacity.

This article reported a case of successful delivery in a woman with right atrial angiosarcoma and ovarian metastasis. At 31 weeks of gestation, the pregnant woman experienced dyspnea, osphyalgia, nausea, and vomiting. An echocardiogram performed at a local hospital indicated a hypoechoic mass in the right atrium. On December 12, 2023 (32 weeks of gestation), she was transferred to the Third Affiliated Hospital of Guangzhou Medical University. On admission, cardiac ultrasound suggested an irregular slightly high echo in the right atrium, and MRI indicated a malignant tumor. On the day of admission, the patient underwent cardiac exploratory surgery and cesarean section. An enlarged left ovary was found during the surgery, and postoperative pathology confirmed primary right atrial angiosarcoma with left ovarian metastasis. The patient was transferred to the intensive care unit for further treatment. At the request of her family, she was discharged after her condition improved (11 d after the surgery). A male infant who had shallow breathing but did not cry at birth was delivered via cesarean section. He was transferred to the neonatal department for intubation and positive pressure ventilation with a resuscitation bag and was discharged 25 d after birth. The patient was lost to follow-up after discharge.

Objective:To construct a classification model for endoscopic ultrasonography (EUS) images of gastrointestinal stromal tumors (GISTs) and leiomyomas (LM) based on deep learning technology, and to verify its value for differential diagnosis.Methods:From October 2014 to October 2021, 69 patients of GISTs and 73 of LM who underwent EUS and were pathologically confirmed by surgery or endoscopic resection in the Second Affiliated Hospital of Soochow University were retrospectively studied. One clear EUS image with typical lesion was selected for each case. Using the hold-out method, the images of each disease were divided into the training set and the validation set according to the ratio of the number of images in the training set to the number of images in the validation set, which was 8∶2. Finally, 113 EUS images (55 GISTs and 58 LM) were used to form the training set, and 29 EUS images (14 GISTs and 15 LM) were used to form the validation set. The training set was used to train and optimize the deep learning model, and the validation set was used to verify the classification model. The main observation indicators included the sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of differential diagnosis.Results:The accuracy of the classification model established by Resnet 34 network structure in the differential diagnosis of GISTs and LM tended to be 0.89, better than the classification model established by Resnet 50 network structure (0.81). The sensitivity, the specificity, the positive predictive value, the negative predictive value and the accuracy of the classification model based on Resnet 34 network structure for differentiating EUS images in the validation set were 85.71% (12/14, 95% CI: 67.38%-100.00%), 93.33% (14/15, 95% CI: 80.71%-100.00%), 92.31% (12/13, 95% CI: 77.82%-100.00%), 87.50% (14/16, 95% CI: 71.30%-100.00%) and 89.66% (26/29, 95% CI: 78.57%-100.00%), respectively. Conclusion:It is feasible to use deep learning technology in the differential diagnosis of EUS images of GISTs and LM, which can provide auxiliary diagnostic opinions for clinicians. The deep learning model based on Resnet 34 network structure shows higher accuracy in the differential diagnosis of EUS images of GISTs and LM.

Objective To assess the influences of self-and interviewer-administered methods on the scores of anxiety and depression questionnaires among the patients with sports injuries.Methods A total of 532 participants with sports injuries treated in the Sports Medicine Center of West China Hospital,Sichuan University from November 2022 to May 2023 were included.They were randomly assigned to either the interviewer-administered group(n=270)or the self-administered group(n=262)to complete the generalized anxiety disorder(GAD-7)and the patient health questionnaire(PHQ-9)scales.The total scores and prevalence rates of anxiety and depres-sion were compared between the two groups.Results There was no statistically significant difference in gender,occupation,or surgical site between the two groups(all P＞0.05).The self-administered group had higher scores of GAD-7 and PHQ-9 scales than the interviewer-administered group(P＜0.001,P＜0.001).A greater proportion of participants in the self-administered group than in the interview-administered group met the criteria for mild to moderate anxiety and depression(P＜0.001,P=0.002).The prevalence rates of moderate to se-vere anxiety(GAD-7 ≥10)and depression(PHQ-9 ≥10)showed no statistically significant difference between the two groups(P=0.761,P=0.086).Conclusion This study demonstrates that the participants in the self-administered group are more likely to report mild to moderate symptoms of anxiety and depression than those in the interviewer-administered group.

Objective To evaluate the efficacy of transurethral resection of bladder tumor(TURBT)in treating cystitis glandularis(CG),and to explore the influencing factors.Methods A retrospective analysis was conducted on 243 CG patients treated with TURBT during Jan.2013 and Dec.2020 in our hospitals.Postoperative efficacy was assessed using global response assessment(GRA).The correlation between GRA score and the demographic characteristics,comorbidities,initial complaints,and postoperative recurrence was determined with logistic regression analysis.Results Among the 243 patients,3.70％(9/243)had dysplasia,2.47％(6/243)had exuberant hyperplasia of Brinell's nest,and 2.06％(5/243)had intestinal metaplasia.The mean GRA score was(2.02±0.72)after a follow-up of(47.10±28.53)months.Re-operation was performed in 10.29％(25/243)of the patients due to recurrence,and the improvement of hydronephrosis and dysuria was 70.59％(12/17)and 50.00％(15/30),respectively.Pelvic fat increase developed in 1 patient(0.41％)after surgery.Logistic regression analysis showed that postoperative GRA score was not significantly correlated with demographic characteristics,body mass index,comorbidities,alcoholism and postoperative recurrence(P＞0.05).Conclusion TURBT is an effective method in the treatment of CG,which can significantly improve patients'hydronephrosis and dysuria.However,approximately 10％of the patients experience recurrence,necessitating further surgery,which suggests the need for vigilance regarding potential recurrence during treatment.

Objective To investigate the changing trends in etiology and treatment of male urethral stricture in recent 10 years.Methods A total of 940 male patients with urethral stricture admitted to the Department of Urology of Beijing Jishuitan Hospital during Jan.2013 and Dec.2022 were continually collected.The clinical data were divided into two groups according to the time of admission,namely the group from 2013 to 2017 and the group from 2018 to 2022,for a comparative analysis of the previous and subsequent 5 years.The etiology,location,length and the type of treatment of urethral stricture were retrospectively analyzed.Results The causes of the 940 cases of male urethral stricture were trauma in 447(47.55％),iatrogenic injury in 220(23.40％),idiopathic causes in 128(13.62％),lichen sclerosus(LS)in 78(8.30％),infection in 46(4.89％),and other causes in 21(2.23％).The treatment methods were urethroplasty in 691(73.51％),direct vision internal urethrotomy(DVIU)in 122(12.98％),urethral dilatation in 86(9.15％),and suprapubic cystostomy in 41(4.36％).Compared with the previous 5 years,in the past 5 years,the proportion of urethral stricture caused by trauma decreased significantly(60.34％vs.41.71％,P＜0.001),while the proportion of iatrogenic injury increased significantly(17.63％vs.26.05％,P=0.005).In the past 5 years,the proportion of urethroplasty increased from 68.81％to 75.66％(P=0.027),while the proportion of DVIU decreased from 19.66％to 9.92％(P＜0.001).Inthe past 5 years,the proportion of membranous urethral stenosis decreased significantly(26.98％vs.50.85％,x2=51.06,P＜0.001),the proportion of penile urethral stricture(21.40％vs.7.80％,=26.37,P＜0.001)and meatal stenosis(9.30％vs.4.75％,x2=5.80,P＜0.001)increased significantly.Conclusion In the past decade,trauma was the main cause of male urethral strictures,but its proportion showed a decreasing trend.Iatrogenic injury led to a gradual increase in urethral strictures,which was the second leading cause of male urethral stricture.The application of urethroplasty increased significantly,making it the main treatment method for male urethral stricture.

Objective:To investigate the risk factors and prognostic value of the textbook outcome (TO) in patients with advanced gastric cancer (AGC) who underwent neoadjuvant chemotherapy followed by surgical resection.Methods:This is a retrospective cohort study. A total of 253 patients with AGC who underwent neoadjuvant chemotherapy combined with gastrectomy and D2 lymphadenectomy in the Department of Gastric Surgery, Fujian Medical University Union Hospital from January 2010 to December 2019 were retrospectively included. There were 195 males and 58 females, aged (60.3±10.0) years (range: 27 to 75 years). The patients were then divided into the TO group ( n=168) and the non-TO group ( n=85). Multivariate Logistic regression was used to analyze the independent predictors of TO. Univariate and multivariate Cox analysis were used to analyze independent prognosis factors for overall survival (OS) and disease-free survival (DFS). Propensity score matching was performed to balance the TO and non-TO groups, and the Kaplan-Meier method was used to calculate survival rates and draw survival curves. Results:Among the 253 patients, 168 patients (66.4%) achieved TO. The Eastern Cooperative Oncology Group score ( OR=0.488, 95% CI: 0.278 to 0.856, P=0.012) and ypN stage ( OR=0.626, 95% CI:0.488 to 0.805, P<0.01) were independently predictive of TO. Multivariate analysis revealed that TO was an independent risk factor for both OS ( HR=0.662, 95% CI: 0.457 to 0.959, P=0.029) and DFS ( HR=0.687, 95% CI: 0.483 to 0.976, P=0.036). After matching, the 5-year OS rate (42.2% vs. 27.8%) and the 5-year DFS rate (37.5% vs. 27.8%) were significantly higher in the TO group than in the non-TO group (both P<0.05). Furthermore, patients in the non-TO group benefited significantly from postoperative chemotherapy (both P<0.05), but those in the TO group did not (both P>0.05). Conclusion:TO is an independent prognosis factor in patients undergoing neoadjuvant chemotherapy and surgery for AGC and is associated with postoperative chemotherapy benefits.
