Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

PURPOSE: Postpancreatectomy hemorrhage (PPH) is a life-threatening complication after pancreatoduodenectomy. Stent-graft implantation is an emerging treatment option for PPH. This study reports the outcome of PPH treated with stent-graft implantation. METHODS: This was a single-center, retrospective study. Between April 2020 and December 2023, 1723 pancreatectomy cases were collected while we screened 12 cases of PPH after pancreatoduodenectomy treated with stent-graft implantation. Patients' medical and radiologic images were retrospectively reviewed. Technical and clinical success, complications, and stent-graft patency were evaluated. Continuous data are reported as means ± standard deviation when normally distributed or as median (Q₁, Q₃) when the data is non-normal distributed. Categorical data are reported as n (%). A p < 0.05 was considered statistically significant. Kaplan-Meier estimates were used for stent patency and patients' survival. RESULTS: Pancreatic fistula was identified in 6 cases (50.0%), and pseudoaneurysm was identified in 3 cases (25.0%), including pancreatic fistula together with pseudoaneurysm in 1 case (8.3%). All pseudoaneurysm or contrast extravasation sites were successfully excluded with patent distal perfusion, thus technical success was achieved in all cases. The overall survival rate at 6 months and 1 year was 91.7% and 78.6%, respectively. One patient had herniation of the small intestine into the thoracic cavity, which caused a broad thoracic and abdominal infection and died during hospitalization. Rebleeding occurred at the gastroduodenal artery stump in 1 case after stent-graft implantation for the splenic artery and was successfully treated with another stent-graft implantation. Two cases of asymptomatic stent-graft occlusion were observed at 24.6 and 26.3 after the operation, respectively. CONCLUSIONS With suitable anatomy, covered stent-graft implantation is an effective and safe treatment option for PPH with various bleeding sites and causes.

Objective:To evaluate the feasibility and safety of a fascial space priority approach to total pelvic exenteration (TPE) in patients with pelvic malignancy.Methods:This was a descriptive case series. Relevant clinical data of patients who had undergone TPE via a fascial space priority approach at Tianjin Union Medical Center from September 2017 to March 2025 were retrospectively collected. All operations had been performed via a fascial space priority approach, the guiding principle of which is separating the avascular pelvic spaces first and then transecting the vessels and nerves of the pelvic organs. That is, the avascular planes around all the pelvic organs are dissected first, after which the relevant vessels and nerves are fully dissected and transected, followed by en bloc resection of pelvic organs distally or via perineal approach. The variables studied included relevant surgical parameters, postoperative pathological findings, complications (classified according to the Clavien-Dindo criteria); recurrence-free survival (RFS), overall survival, and tumor-specific survival. Results:The study cohort comprised 41 patients, including 30 (73.2%) with primary tumors and 11 (26.8%) with recurrent tumors. Open TPE was performed on five patients (12.2%) and laparoscopic TPE on the remaining 36 (87.8%). All procedures were successfully completed with a fascial space priority approach and there were no intraoperative deaths. R0 resection was achieved in 34 patients (82.9%) and R1 resection in seven (17.1%). The operation time was 500 (265-740) min, and the amount of bleeding 200 (10-3,500) mL. Twelve patients (29.3%) developed postoperative complications, two of which were Clavien-Dindo Grade III complications. One of these patients required re-operation to manage a pelvic hematoma 29 days after the primary TPE. No active bleeding was observed during the re-operation. Another patient underwent interventional angiography for an episode of postoperative bleeding; this showed a pseudoaneurysm of the internal iliac artery that was successfully treated by interventional embolization via the internal iliac artery. Five days after undergoing a primary TPE with bladder preservation, a third patient was found to have a urinary fistula and underwent laparoscopic bladder resection with percutaneous ureterostomy. The median duration of follow-up was 18 (1-90) months. The 5-year RFS and overall survival were 46.7% and 52.2%, respectively, whereas the 5-year tumor-specific survival was 67.8%. Univariate Cox regression analysis identified a positive surgical margin ( P < 0.001), lateral pelvic sidewall invasion ( P=0.014), and vascular invasion ( P=0.004) as significantly associated with RFS, whereas multivariate analysis identified only a positive surgical margin (HR: 21.93, 95% CI: 3.78-127.42, P<0.001) as an independent predictor of RFS. Conclusions:It is safe and feasible to perform TPE with a fascial space priority approach on patients with pelvic malignancy. Positive surgical margins are significantly associated with RFS.
