Objective To evaluate the efficacy and safety of Mirabegron combined with transcutaneous tibial nerve stimulation (TTNS) in the treatment of drug-refractory overactive bladder (OAB), so as to alleviate patients'symptoms, improve their quality of life with optimized treatment plan, and provide reference for clinical practice. Methods A retrospective analysis was conducted on 56 patients with drug-refractory OAB treated at the Department of Urology of Gansu Provincial Hospital during Jan.2023 and Dec.2024. Based on the treatment methods, the patients were divided into two groups:the TTNS group and the combined treatment group, with 28 patients in either group. The daytime urination frequency, nocturia frequency, urgency episodes, urinary incontinence, functional bladder capacity (FBC), OAB symptom scores (OABSS), and incontinence quality of life questionnaire (I-QoL) scores were collected before and after treatment. The therapeutic efficacy was evaluated using the Nimodipine method. Results After 12 weeks of treatment, the 24-hour urination indicators in both groups including daytime urination frequency, nocturia frequency, urgency episodes and FBC, as well as OABSS and I-QoL scores, showed a significant improvement compared to baseline (P<0.001). The combined treatment group exhibited fewer urgency episodes than the TTNS group [ (1.07±0.66) times/24 h vs. (1.64±0.62) times/24 h, P<0.05]. However, no statistically significant differences were observed between the two groups in other urinary parameters (P>0.05). The total effective rate in the combined treatment group was 96.43%, which was significantly higher than that in the TTNS group (82.14%, P<0.05). During treatment, one patient (3.57%) in the TTNS group experienced mild skin allergy, which recovered following symptomatic management. Conclusion The combination of TTNS and Mirabegron in drug-refractory OAB not only alleviates clinical symptoms and improves quality of life, but also shows superior efficacy in reducing urgency episodes. This approach is a safe and effective treatment option.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a refractory condition characterized by chronic inflammation of the bladder wall, disruption of the urothelial barrier, and neural sensitization. Current therapies, such as oral pentosan polysulfate sodium (PPS) or intravesical hyaluronic acid instillations, offer limited efficacy due to transient effects and an inability to reverse tissue fibrosis. Platelet-rich plasma (PRP), a regenerative medicine approach, has demonstrated significant therapeutic potential in urological disorders through the synergistic actions of its multiple growth factors. This review summarizes the latest advances in PRP therapy for IC/BPS, revealing that the underlying mechanisms primarily involve the release of diverse growth factors, suppression of inflammatory responses, restoration of the urothelial barrier, and modulation of nerve axonal regeneration. Clinically, PRP therapy significantly alleviates symptoms including pelvic/bladder pain, urinary frequency, nocturia episodes, and improves patients'quality of life. Furthermore, it offers advantages such as convenient administration, a favorable safety profile, and strong feasibility, presenting new therapeutic methods and options for the clinical treatment of IC/BPS.

Objective:To compare the clinical efficacy and safety of different myotomy procedures during peroral endoscopic myotomy (POEM) for achalasia (AC).Methods:A retrospective study was conducted involving patients diagnosed as having achalasia and underwent POEM at Peking Union Medical College Hospital from April 2020 to October 2023. Patients were divided into conventional myotomy group, short myotomy group and full-thickness myotomy group according to myotomy length and depth. Outcomes including operation duration, procedure-related complications, efficacy and incidence of postoperative reflux esophagitis were compared between conventional vs. short, and conventional vs. full-thickness groups.Results:Among 70 patients, 26 underwent conventional myotomy, 19 short myotomy, and 25 full-thickness myotomy. The short myotomy group demonstrated significantly shorter procedure duration (72.89±20.57 min) compared to the conventional group (91.81±36.70 min, t=2.197, P=0.034). There were no statistically significant differences in procedure-related complications [26.3% (5/19) VS 34.6% (9/26), χ2=0.353, P=0.553], treatment efficacy [94.7% (18/19) VS 96.2% (25/26), χ2=0.052, P=0.820], or incidence of postoperative reflux esophagitis [50.0% (5/10) VS 41.7% (5/12), χ2=0.306, P=0.580] between the short and conventional myotomy groups. No statistically significant differences were observed between the conventional and full-thickness myotomy group in procedure duration (99.64±29.13 min VS 91.81±36.70 min, t=0.336, P=0.404), procedure-related complications [28.0% (7/25) VS 34.6% (9/26), χ2=0.259, P=0.611], treatment efficacy [96.0% (24/25) VS 96.2% (25/26), χ2=0.001, P=0.977], or incidence of postoperative reflux esophagitis [35.7% (5/14) VS 41.7% (5/12), χ2=0.022, P=0.883]. Conclusion:Short myotomy POEM achieves comparable efficacy to conventional myotomy with reduced operative time and no increased complication risk. Full-thickness myotomy demonstrates similar efficacy, operative duration, and safety to conventional myotomy.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA

OBJECTIVES: To evaluate the clinical efficacy of hospital-prepared Chinese medicine Feigan granules for influenza patients. This study has been registered at the International Traditional Medicine Clinical Trial Registry platform (ITMCTR2025000162). METHODS: A prospective observational study was conducted on influenza patients who visited the Fever Clinic of the First Affiliated Hospital, Zhejiang University School of Medicine between February and March 2024. Patients were divided into the observation group (Feigan granules combined with conventional Western medicine) and the control group (conventional Western medicine). Main symptoms (including fever, cough and sore throat) and secondary symptoms (including chest tightness, poor appetite, muscle soreness and dry mouth) were evaluated with traditional Chinese medicine (TCM) symptom scale on the first day of the patient's visit and the third day after treatment. The degrees of improvement in the TCM symptom scores before and after treatment were compared using paired rank-sum test, and the differences in the overall symptom efficacy index between two groups were compared using the Wilcoxon test. RESULTS: A total of 217 influenza patients were included. After treatment, the TCM symptom scores of both groups were significantly improved compared with those before treatment (all P<0.01). The median differences in the main symptom score before and after treatment in the observation and the control groups were 7 points (95%CI: 6.0-8.0) and 6 points (95%CI: 6.0-8.0), respectively. The median difference in the secondary symptom score was 3 points (95%CI: 2.0-4.0) in both groups. The median differences in the total score were 9 points (95%CI: 8.0-10.5) and 8 points (95%CI: 7.0-10.0) in the observation and control groups, respectively. In the subgroup with an initial cough score >2, the improvement rates of total score (97.06% vs. 92.59%) and secondary symptoms (92.31% vs. 85.11%) in observation group were significantly higher than those in the control group (P<0.05); while there was no significant difference in the improvement rate of the main symptoms (95.59% vs. 90.74%, P>0.05). CONCLUSIONS Feigan granules can improve the TCM syndromes of influenza patients, especially for patients with more severe cough.

Objective To explore the influencing factors of self injury or suicide in adolescent patients with depression.Methods A total of 96 adolescents who were diagnosed with depressive disorder at Yunnan Psychiatirc Hospital and Kunming Psychiatirc Hospital from January 2023 to May 2024 were selected for the study.The case group consisted of 61 adolescents who had self-injury or suicidal behaviors within 30 days,while the control group consisted of 35 adolescents who had no self-injury or suicidal behaviors within at least 30 days.Assessments were performed using the Patient Health Questionnaire-9(PHQ-9),Millon Screening Inventory for Borderline Personality Disorder(MSI-BPD),House-Tree-Person Drawing Test(HTP),and the Columbia Suicide Severity Rating Scale(C-SSRS).Among these,72 subjects underwent skin pressure pain threshold testing using the Algometer HP-50,with 12 in the self-harm or suicide group within 2 days and 60 in the group beyond 2 days.Results(1)Analysis of gender and age between the two groups showed statistically significant differences(P<0.05),with a higher proportion of females and younger ages in the 30-day group;(2)The PHQ-9 score for the 30-day group was(19.59±5.99),with a score of(2.41±0.97)for item 9("Thoughts that it would be better to be dead or to hurt oneself in some way"),and an MSI-BPD score of(7.43±1.61).The scores for the group over 30 days were(10.89±7.99),(1.00±1.11)for item 9,and(5.40±3.13)for MSI-BPD.Independent samples t-test analysis showed significant differences(P<0.01);(3)In the 30-day group,five drawing characteristics from the 47 HTP characteristics(shift of center of gravity,hair not disheveled or no hair,no mountains,no sun,and no flowers or grass)were found to occur at a higher rate,with statistical significance(P<0.05);(4)In the binary logistic regression analysis of 96 patients with the 30-day suicide or self-injury behavior as the dependent variable,the absence of flowers and PHQ-9 question 9 score are the risk factors for adolescent depression patients to have self-injury or suicide behavior within 30 days(OR no flowers=7.934,OR score on PHQ-9 question 9=3.554).(5)Among the 72 subjects the skin pressure pain threshold for adolescents who exhibited self-injure or suicide behaviors within 2 days(8.83±4.27 N)was significantly higher than that for patients beyond 2 days(6.48±3.00 N),with statistical significance(t=-2.201,P<0.05).Additionally,the score for item 9 of the PHQ-9 was higher(2.50±0.67 vs 1.87±0.95),also showing statistical significance(t=-2.201,P<0.05).Conclusion The absence of flowers or grass in HTP painting,and stronger suicidal ideation or suicide attempt are risk factors for self-injury or suicidal behavior in adolescents with depression.Furthermore,those who self-injure or commit suicide within 2 days have a higher pain threshold compared to those beyond 2 days.

Objective To explore the methods of continuing education for advanced endoscope operations by diges-tive specialists through the establishment and teaching effect evaluation of the ERCP(endoscope retrograde cholan-giopancreatography)introductory training mode.Methods A total of 26 trainees from 3 sessions of the ERCP intro-ductory training courses at Peking Union Medical College Hospital from September 2023 to September 2024 were in-cluded.The teaching effects of the training courses and its 5 modules were subjectively and objectively evaluated by questionnaires,on-site tests and evaluations by senior ERCP operators.Results Through the ERCP introductory training courses,the trainees'self-evaluated proficiency in duodenoscope structure(pre-training:2.4±2.4,post-training:8.2±1.5,P＜0.001),duodenoscope operation(pre-training:1.2±2.2,post-training:6.6±1.8,P＜0.001),papillary cannulation(pre-training:0.5±1.3,post-training:5.4±1.8,P＜0.001),intra-bile duct operation(pre-training:0.2±0.6,post-training:4.9±2.1,P＜0.001),and identification of intra-bile duct lesions(pre-training:1.7±2.1,post-training:6.0±2.0,P＜0.001)was significantly improved.The accuracy rate of the trainees'theoretical tests and picture recognition before training was 37.2％and then increased up to 62.8％after training.Before training,all trainees were considered by senior operators as not ready to start ERCP training on real patients,while after training,69.2％(18/26)of the trainees were considered ready to start ERCP training on real patients.Conclusions The multi-module ERCP introductory training courses have a significant effect in terms of laying a foundation for trainees to start ERCP training on patients and of providing a reference for the con-tinuing education mode of advanced endoscope operations for digestive specialists in China.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.
