Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

Iron overload is strongly associated with heart disease. Ferroptosis is a new form of regulated cell death indicated in cardiac ischemia-reperfusion (I/R) injury. However, the specific molecular mechanism of myocardial injury caused by iron overload in the heart is still unclear, and the involvement of ferroptosis in iron overload-induced myocardial injury is not fully understood. In this study, we observed that ferroptosis participated in developing of iron overload and I/R-induced cardiomyopathy. Mechanistically, we discovered that Parkin inhibited iron overload-induced ferroptosis in cardiomyocytes by promoting the ubiquitination of long-chain acyl-CoA synthetase 4 (ACSL4), a crucial protein involved in ferroptosis-related lipid metabolism pathways. Additionally, we identified p53 as a transcription factor that transcriptionally suppressed Parkin expression in iron-overloaded cardiomyocytes, thereby regulating iron overload-induced ferroptosis. In animal studies, cardiac-specific Parkin knockout mice (Myh6-CreER ^T2 /Parkin ^fl/fl ) fed a high-iron diet presented more severe myocardial damage, and the high iron levels exacerbated myocardial I/R injury. However, the ferroptosis inhibitor Fer-1 significantly suppressed iron overload-induced ferroptosis and myocardial I/R injury. Moreover, Parkin effectively protected against impaired mitochondrial function and prevented iron overload-induced mitochondrial lipid peroxidation. These findings unveil a novel regulatory pathway involving p53-Parkin-ACSL4 in heart disease by inhibiting of ferroptosis.

This report described the diagnosis and management of a 28-year-old pregnant woman with ectopic pheochromocytoma of the urinary bladder. At 27 +5 weeks of gestation, the patient developed sudden headache and hypertension [peak blood pressure 173/116 mmHg (1 mmHg=0.133 kPa)] following urination, initially misdiagnosed as preeclampsia. Ultrasonography and MRI revealed a 4.2 cm×3.0 cm×3.3 cm mass in the bladder trigone, with significantly elevated plasma normetanephrine levels confirming ectopic pheochromocytoma. Following multidisciplinary consultation, blood pressure was controlled with phenoxybenzamine and labetalol. Pregnancy was prolonged to 35 weeks when cesarean delivery was performed with concurrent complete tumor resection. Pathology confirmed bladder paraganglioma, with favorable maternal and neonatal outcomes. This case highlights the importance of differential diagnosis for secondary hypertension during pregnancy, emphasizing that early diagnosis and individualized management are crucial for optimizing maternal and fetal outcomes.

Objective:To investigate the influencing factors of adverse reactions of reconstructive flaps after postoperative precision radiation therapy for head and neck tumors.Methods:Medical records of 46 patients who underwent radiotherapy after flap reconstruction for head and neck tumors in the Affiliated Hospital of Inner Mongolia Medical University between January 2016 and October 2022 were retrospectively analyzed. The overall survival (OS), local regional control (LRC) and dosimetric parameters after radiotherapy were analyzed. The adverse reactions mainly including radiation dermatitis and flap necrosis at 3 and 6 months after radiotherapy, flap atrophy, flap fibrosis, dysphagia and chewing dysfunction at 12 and 24 months after radiotherapy were recorded. Adverse reactions were graded using the common terminology criteria for adverse events (CTCAE) version 5.0. Quantitative data were analyzed by one-way analysis of variance or rank-sum test. Qualitative data were analyzed by chi-square test or Fisher's exact test. Multivariate analysis of influencing factors of adverse reactions was performed using binary logistic stepwise regression.Results:All 46 patients were aged 57.6 years on average. The median follow-up time was 65 months (12-100 months). After the follow-up, 22 patients died, 6 recurred, and 7 had distant metastases. The 5-year OS rate was 48% and 5-year LRC rate was 69%. The incidence of radiation dermatitis was decreased over time after the end of radiotherapy: 80% (37/46) and 65% (30/46) at 3 months and 6 months after radiotherapy, respectively. The incidence of grade 3 radiation dermatitis was 11% (5/46) and 0 at 3 and 6 months after radiotherapy, respectively. The incidence of grade 2 flap necrosis was 4% (2/46) at 3 months after radiotherapy. At 12 months after radiotherapy, the incidence of flap atrophy and fibrosis was 83% (38/46) and 67% (31/46) , and the incidence of grade 3 flap atrophy and fibrosis was equally 4% (2/46) , respectively. All patients had dysphagia and chewing dysfunction at 12 months after radiotherapy. At 24 months after radiotherapy, 83% (38/46) and 61% (28/46) of patients still had dysphagia and chewing dysfunction. Multivariate regression analysis showed that irradiated flap volume, total radiotherapy dose, pharyngeal constrictor D mean and pharyngeal constrictor V 60 Gy, the interval between surgery and radiotherapy, gender and age were the independent influencing factors of adverse reactions of reconstructive flaps after precision radiation therapy for head and neck tumors. Conclusions:For patients undergoing flap reconstruction for head and neck tumors, under the premise of ensuring tumor control, the dose to normal tissue and flap blood supply area should be strictly limited, the irradiated volume should be reduced, and the interval between surgery and radiotherapy should be shortened (≤6 weeks) to reduce the risk of adverse reactions. Hypo-fractionated radiotherapy plan should be formulated or the total radiotherapy dose should be appropriately adjusted for elderly patients to reduce long-term complications.
