Acute esophagogastric variceal bleeding (AEGVB) is one of the life-threatening complications of decompensated cirrhosis. Endoscopy is the main method for the diagnosis and treatment of AEGVB, and endoscopic treatment can effectively control acute bleeding and alleviate or eliminate varices. However, there is still a lack of consistent recommendations for the timing of endoscopic examination and intervention for AEGVB in related guidelines in China and globally. Existing studies in China and globally have low quality of evidence, with significant variations in the definition of “early endoscopy” and inconsistent conclusions. This article reviews the research advances in the timing of endoscopic treatment for AEGVB in liver cirrhosis, points out the controversies over the optimal timing of treatment, and discusses future research directions in this field.

Objective To explore the efficacy and safety of blue laser vaporization in the treatment of large-volume (>80 mL) benign prostatic hyperplasia (BPH). Methods A retrospective analysis was conducted on the clinical data of 149 BPH patients with prostate volume>80 mL who underwent blue laser vaporization at our hospital during Aug. 2023 and Aug. 2025. The 1-month postoperative maximum urinary flow rate (Qmax) and international prostate symptom score (IPSS), operation time, postoperative hemoglobin drop, bladder irrigation volume, catheter indwelling time, and incidence of postoperative complications were recorded and analyzed. Results All operations were successfully completed, without conversion to other approaches. The operation time was (41.47±11.05) minutes, postoperative hemoglobin drop (2.78±1.19) g/L, bladder irrigation volume (9.97±1.49) bags, and catheter indwelling time (3.30±1.85) days. One month after surgery, the Qmax was significantly higher than the preoperative value [(20.19±3.39) mL/s vs. (2.39±2.17) mL/s], while the IPSS was significantly lower [(4.46±0.87) vs. (27.69±2.06)], with statistically significant differences (P<0.001). Postoperative complications included 1 case of incontinence (0.67%), 2 cases of urethral stricture/bladder neck contracture (1.34%), and 1 case of secondary bleeding (0.67%), all of which improved with symptomatic treatment. Conclusion Blue laser vaporization is effective for treating large-volume BPH, with advantages such as minimal bleeding risk, short operation time, fast recovery and safety.

Objective:
To utilize machine learning(ML) algorithms to develop accurate and effective prediction models for TAC dose/weight-adjusted trough concentration(C0/D).
Methods:
Data were collected on 264 TAC blood concentration monitoring data from 72 patients undergoing kidney transplantation. The effects of population statistical data, clinical features, combined medication, and ultrasound feature parameters on TAC C0/D were analyzed. Features with a significance level less than 0.05 in the univariate analysis of TAC C0/D were selected for inclusion in the random forest(RF) algorithm to identify significant features. These features were interpreted using partial dependency plots. Five ML algorithms, including RF, support vector regression(SVR), extreme gradient boosting(XGBoost), decision trees(DT) and artificial neural networks(ANN), were employed to establish the TAC C0/D prediction model. Hyper-parameter tuning was performed on the RF model that performed the best.
Results :
Ten characteristic variables with importance scores>5 were retained and included in the ML model: transglutaminase, red blood cell count, blood urea nitrogen, weight, serum creatinine, renal segmental arterial resistance index, renal aortic resistance index, hematocrit, renal pelvic Young′s modulus value, and time after transplantation. The partial dependence plots showed that all 10 important variables screened were positively correlated with TAC C0/D. The tuned RF model outperformed the other models with aR2of 0.81, aRMSEof 43.93, and aMAEof 29.97.
Conclusion
The ML models demonstrate good performance in predicting TAC C0/D and provide innovative interpretations using partial dependence plot. The optimized RF model shows optimal performance and offers a novel tool for individualized medication adjustment for TAC in renal transplant patients.

ObjectiveTo investigate the influenza virus infection status of influenza-like illness (ILI) at a sentinel hospital in Baoshan District of Shanghai, to explore the seasonal patterns of influenza, so as to provide a scientific basis for influenza prevention and control in Baoshan District of Shanghai. MethodsSurveillance data and pathogenic testing results of ILI from the monitoring year of 2015 to 2023 were collected from the sentinel hospital to describe the seasonal epidemic characteristics of influenza in this district. ResultsThe proportion of ILI visits to sentinel hospital in Baoshan District of Shanghai showed an upward trend from 2015 to 2023 (Z=2.598, P=0.09). The positive rate of influenza virus in ILI was 20.43% (1 761/8 621), of which 14.17% were positive for influenza A virus, including 8.43% for influenza A/H3N2 and 5.74% for influenza A/H1N1. The positive rate of influenza B virus was 6.25%, of which the positive detection rate of influenza B/Victoria virus was 5.35%, while that of influenza B/Yamagata virus was 0.90%. Influenza B/Yamagata virus was not detected in 2019‒2023. The highest positivity rate was observed in the 5‒<15 years age group (25.57%). The positive rate of ILI was lower in males (19.90%) than that in females (20.90%). There were three patterns of influenza epidemic in the district: with year-round circulation in 2016‒2017 and 2021‒2022; with bimodal peaks in 2015‒2016, 2017‒2018 and 2022‒2023; and with one peak in 2018‒2019 and 2019‒2020. The positive rate of influenza virus exhibited seasonal variations, with influenza A virus predominated in summer and autumn. However, influenza B virus showed an increase in spring and winter. ConclusionThe influenza epidemic in Baoshan District, Shanghai exhibits diverse patterns with heterogeneous epidemiological characteristics across different age groups and seasons. Notably, children and adolescents aged 5‒<15 years constitute the key target population for influenza prevention and control. Enhanced surveillance and targeted control measures against influenza A/H3N2 lineage viruses are particularly warranted during summer and autumn seasons.

Objective:To delineate clinical characteristics of infantile myofibroma/myofibromatosis (IM) .Methods:A retrospective analysis was conducted on histologically confirmed IM cases from Beijing Children's Hospital, Henan Children's Hospital, and Maternity and Child Health Care of Guangxi Zhuang Autonomous Region between August 2014 and July 2021. The clinical, pathological, imaging features, and outcomes were analyzed and summarized.Results:A total of 44 IM patients were included, comprising 28 males (63.6%) and 16 females (36.4%). Their ages at onset ( M[ Q1, Q3]) were 14.8 (4.7, 42.4) months, and 26 patients (59.1%) developed IM before the age of 1 year. Seven patients (15.9%) were initially diagnosed with IM. Skin involvement occurred in 42 patients (95.5%), of whom 30 (71.4%) presented with a solitary lesion and 12 (28.6%) with multiple lesions. Skin lesions mainly manifested as painless, firm nodules or masses. The most commonly involved extracutaneous site was the skeletal system (21/44, 47.7%). Histopathological examination of all 44 IM cases revealed a biphasic architecture pattern, characterized by the coexistence of two distinct morphologies or cell types within the tumor tissues (including spindle cell areas composed of fascicularly and densely arranged myofibroblasts, and primitive mesenchymal cell areas composed of small, round undifferentiated cells. Immunohistochemical study was performed in 42 cases; 40 (95.2%) were positive for smooth muscle actin, and 20 (47.6%) were positive for CD34. Genetic testing was conducted in 3 cases, and NOTCH mutations were identified in 2. Among the 44 patients, 30 patients (68.2%) underwent surgical excision, 5 patients (11.4%) received intralesional injections of triamcinolone acetonide, 1 patient (2.3%) received chemotherapy for intestinal involvement, and 8 patients were managed expectantly. During the follow-up of 49 (36, 60) months, lesions completely resolved in 42 cases (95.5%), while 2 cases died of pulmonary infection following chemotherapy or postoperative airway compression. Conclusions:IM predominantly affected infants and young children, with the skin and skeletal system being the most commonly involved sites. Skin lesions often manifested as firm nodules or masses, and histopathological examination was crucial for definitive diagnoses. Most IM cases exhibited favorable outcomes.
