Objective:To explore the short-term oncological efficacy of the total prostatic urethra preservation(TPUP)technique in laparoscopic radical prostatectomy and its impact on postoperative urinary continence rate.Methods:The clinical data of 17 prostate cancer patients admitted to Shaoxing People’s Hospital from July 2023 to July 2024 were retrospectively analyzed. The age was(70.5 ± 6.5)years,the body mass index was(23.6 ± 2.5)kg/m 2,and the prostate-specific antigen(PSA)level was(7.845 ± 3.929)ng/ml. The preoperative biopsy pathological Gleason score were 6 in 8 cases,and 7 in 9 cases. All patients underwent laparoscopic radical prostatectomy,and the TPUP technique was used during the operation. The integrity of the preserved urethra was improved by preserving the prostatic surgical capsule closely attached to the corpus spongiosum of the urethra. During the operation,the urethra was completely preserved in 2 cases,nearly completely preserved in 14 cases,and partially preserved in 1 case. The recovery of urinary continence on the day of catheter removal and at 1 and 3 months after the operation was recorded. Recovery of urinary continence was defined as pad within 24 hours. PSA was re - examined at 6 weeks and 3 months after the operation. Results:All 17 operations in this study were successfully completed. The operation time was(143.6 ± 31.6)minutes,and the intraoperative blood loss was 50.0(20.0,50.0)ml. None of the cases was converted to open surgery,and no Clavien - Dindo grade ≥ 2 complications such as blood transfusion or intestinal injury occurred during the peri-operative period. The PSA levels at 6 weeks and 3 months after the operation were 0.054(0.008,0.215)ng/ml and 0.008(0.005,0.037)ng/ml,respectively. The indwelling catheter time after the operation was(13.4 ± 2.1)days. The number of cases with recovered urinary continence on the day of catheter removal and at 1 and 3 months after the operation was 10,15,and 17,respectively.Conclusions:The TPUP technique in laparoscopic radical prostatectomy leads to good recovery of postoperative urinary continence,and there is a slowly PSA decrease in the short term.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective To investigate the risk factors of pancreatic pseudocysts(PPC) in patients with acute pancreatitis (AP) in a retrospective cohort study. Methods 460 AP patients with complete follow-up data admitted in Affiliated Hospital of Qingdao University from January 2004 to March 2012 were retrospectively analyzed,who were divided into PPC group and control group. Age,gender,body mass index(BMI),history of diabetes,etiology,the presence of ascites and hydrothorax,the presence of abdominal mass,the presence of acute fluid collection, APACHEⅡ score at 48 h admission, CT severity index (CTSI), serum albumin, amylase,LDH,ALP, BUN, Cr, TG, TB, conjugated bilirubin, CRP, serum calcium and other laboratory markers were recorded. Univariate logistic regression analysis was used to select the factors that were statistically different between two groups, and multivariate logistic regression analysis was performed to determine the independent risk factors for AP complicated with PPC. Results 143(31.1%) of 460 AP patients developed PPC. On univariate analysis, a total of 11 factors including male sex, BMI ≥28 kg/m2, history of diabetes, alcoholic pancreatitis, ascites, pleural effusion, palpable abdominal mass, acute fluid collections,APACHEⅡscore,CTSI≥7 and serum albumin were statistically different between two groups. On multiple logistic regression analysis, it was shown that male sex (OR 3.23, 95% CI 1.560~ 6.301, P=0.03),history of diabetes (OR 2.23,95% CI 1.021~3.920,P=0.04), ascites (OR 1.62,95% CI 0.652~2.432, P=0.01), pleural effusion (OR 2.43, 95% CI 1.201~7.201, P=0.03), a palpable abdominal mass(OR 1.83,95% CI 0.737~4.320,P<0.001) and CTSI≥7(OR 5.12,95% CI 1.890~14.012, P<0.001) were independent risk factors significantly associated with the PPC formation. Conclusions The male sex, diabetic history, ascites, pleural effusion, palpable abdominal mass and high CTSI score were the independent risk factors of PPC formation in AP.

PURPOSE: This study was aimed to investigate the effect of pseudolaric acid B (PAB) on proliferation, invasion and epithelial-to-mesenchymal transition (EMT) in pancreatic cancer cells and to explore the possible mechanism. MATERIALS AND METHODS: The pancreatic cancer cell line SW1990 was cultured and treated with PAB dose- and time-dependent manners. Cell proliferation and invasion ability were measured by MTT assay and Matrigel/Transwell test, respectively. Semi-quantitative real-time polymerase chain reaction and Western blotting were conducted to detect the expression of EMT markers and the key molecules. Finally, nude mice subcutaneous transplantation tumor model was used to confirm the therapy efficacy of PAB. RESULTS: PAB could inhibit SW1990 cell proliferation and invasion in time- and dose-dependent manners. Vimentin, fibronectin, N-cadherin, Snail, Slug, YAP, TEAD1, and Survivin were down-regulated (p < 0.01), while E-cadherin, caspase-9, MST1, and pYAP were up-regulated (p < 0.05). Combined PAB and gemcitabine treatment markedly restricted the tumor growth compared with gencitabin or PAB alone groups. CONCLUSION: PAB could inhibit the proliferation and invasion ability of pancreatic cancer cells through activating Hippo-YAP pathway and inhibiting the process of EMT.
