Autophagy is a conservative lysosome-dependent material catabolic pathway, and exists in all eukaryotic cells. Autophagy controls cell quality and survival by eliminating intracellular dysfunction substances, and plays an important role in various pathophysiology processes. Erectile dysfunction (ED) is a common male disease. It is resulted from a variety of causes and pathologies, such as diabetes, hypertension, hyperlipidemia, aging, spinal cord injury, or cavernous nerve injury caused by radical prostatectomy, and others. In the past decade, autophagy has begun to be investigated in ED. Subsequently, an increasing number of studies have revealed the regulation of autophagy contributes to the recovery of ED, and which is mainly involved in improving endothelial function, smooth muscle cell apoptosis, penile fibrosis, and corpus cavernosum nerve injury. Therefore, in this review, we aim to summarize the possible role of autophagy in ED from a cellular perspective, and we look forward to providing a new idea for the pathogenesis investigation and clinical treatment of ED in the future.

Objective: To explore the key factors affecting the selection and effectiveness of bladder management modalities in patients with spinal cord injury，so as to provide reference for the optimization of individualized bladder management strategies. Methods: The clinical and follow-up data of 78 patients with spinal cord injury treated in our hospital during Jan.1,2013 and Dec.31,2022 were retrospectively analyzed.The distribution of bladder management modalities among different grades of injuries was analyzed. Bowker symmetry test was used to evaluate the difference between bladder management modalities at discharge and at the end of follow-up. Multiple linear regression was used to explore the influencing factors of bladder management effects. Plotting Kaplan-Meier survival curves were adopted to calculate the median time of changes in bladder management. Results: At discharge，there were 9 cases of self-catheterization，19 cases of intermittent catheterization，22 cases of reflexive voiding，26 cases of long-term catheterization，and 2 cases using urinary collector.At the end of follow-up，there were 15 cases of self-catheterization，8 cases of intermittent catheterization，34 cases of reflexive voiding，14 cases of long-term catheterization，and 7 cases using urinary collector.There was a significant difference between the modalities of bladder management at discharge and at the end of follow-up (χ =21.43，P=0.018).Multiple linear regression showed a significant decrease of 8.60 in the total neurogenic bladder symptom score (NBSS) for grade D injuries compared with grade A injuries (P=0.026). The median time to bladder management change was 7.93 months (95%CI:5.44-9.44), with approximately 50% of patients experiencing a change in bladder management within 8 months after discharge. Conclusion: The modalities of bladder management changed significantly after discharge.The grade of injury was a key factor affecting the effectiveness of bladder management.Higher grade was associated with worse effectiveness of bladder management.

Objective:This study aimed to investigate the role of bone morphogenetic protein 2 (BMP2)/Smad8 signaling pathway in T-2 toxin-induced apoptosis of rat articular chondrocytes.Methods:Primary chondrocytes from SD rats were cultured in vitro and exposed to varying concentrations of T-2 toxin (0.00, 0.32, 1.60, 8.00 ng/ml). The changes in chondrocytes survival rate were determined by CCK8, and the apoptosis changes of chondrocytes were determined by TUNEL assay kit. Using a group design, chondrocytes were cultured in complete culture media and culture media containing T-2 toxin (1.60 ng/ml), BMP2 cytokine (500 ng/ml), or T-2 toxin (1.60 ng/ml) + BMP2 cytokine (500 ng/ml), referred to as the control group, T-2 toxin group, BMP2 group, and T-2 toxin + BMP2 group, respectively. The survival rate and apoptosis changes of chondrocytes in each group were determined. The expression levels of Caspase-3, BMP2, BMP receptor Ⅱ (BMP-R Ⅱ), and Smad1/4/5/8 were determined by quantitative real-time PCR. Results:Compared with the 0.00 ng/ml of T-2 toxin group [(100.00 ± 0.00)%, (4.33 ± 0.32)%], the chondrocyte survival rates [(85.77 ± 2.96)%, (72.79 ± 2.31)%, (48.87 ± 1.83)%] of the 0.32, 1.60, and 8.00 ng/ml of T-2 toxin groups were significantly lower ( P < 0.05), and the apoptosis rates [(5.43 ± 0.32)%, (6.17 ± 0.15)%, (5.07 ± 0.13)%] were significantly higher ( P < 0.05). Compared with the control group, the T-2 toxin group had a lower survival rate and a higher apoptosis rate of chondrocytes ( P < 0.05). Compared with the T-2 toxin group, the T-2 toxin + BMP2 group had a higher survival rate and lower apoptosis rate of chondrocytes ( P < 0.05). Compared with the control group, the T-2 toxin group showed higher expression level of Caspase-3 mRNA in chondrocytes, while the expression levels of BMP2, BMP-R Ⅱ, and Smad1/4/8 mRNA were lower ( P < 0.05). Compared with the T-2 toxin group, the expression level of Caspase-3 mRNA was lower in the T-2 toxin + BMP2 group, while the expression levels of BMP2 and Smad8 mRNA were higher ( P < 0.05). Conclusion:BMP2 may partially block the apoptosis of chondrocytes caused by T-2 toxin by regulating the BMP2/Smad8 signaling pathway.

Objective:To compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) and transperitoneal laparoscopic adrenalectomy (TLA) in the treatment of localized adrenocortical carcinoma (ACC).Methods:The data of 22 patients with stage Ⅰ/Ⅱ ACC underwent laparoscopic adrenalectomy in our institution from January 2009 to December 2018 were retrospectively analyzed. According to the different surgical approaches, these patients were divided into RLA and TLA groups. Eleven patients underwent RLA and 11 patients underwent TLA. There were no significant differences between the RLA group and the TLA group in terms of age at first diagnosis[44 (35, 54) vs. 46(41, 55) years, P= 0.793], sex (male/female: 3/8 vs. 4/7, P = 1.00), secreting tumor ratio (3/11 vs. 4/11, P = 1.00), tumor location (left/right: 6/6 vs. 7/4, P = 1.00), with hypertension or diabetes mellitus (4/11 vs. 3/11, P = 1.00). However, RLA has significantly smaller tumor size [3.0(2.5, 8.4) cm vs. 7.7(5.2, 8.4)cm, P= 0.001], and more stage Ⅰ patients [90.9%(10/11) vs. 18.2%(2/11), P=0.002], compared with those in TLA group. The perioperative indicators and oncology prognosis outcomes were collected and compared between the two groups. The Kaplan-Meier method was performed to calculate the overall survival (OS) and disease-free survival (DFS). Results:Compared with TLA, RLA had shorter operation time[90(70, 100) vs. 110 (90, 120) min, P = 0.005] and postoperative drainage tube removal time [2 (2, 3) vs. 3 (2, 6) day, P = 0.002), and the difference was statistically significant. In the TLA group, one patient was converted to open operation due to intraoperative tumor capsule rupture. For postoperative complications, one patient in the TLA group suffered with wound infection. There were no perioperative deaths in either group. All postoperative pathological examinations confirmed ACC, and there was no significant difference in Ki-67 index between the two groups [10%(3%, 35%) vs. 10%(9%, 25%), P = 0.484]. The median follow-up was similar in the two groups [48(26, 98) vs. 31(18, 49) months, P=0.237]. The local recurrence and metastasis rates were 36.4% for RLA group and 63.6% for TLA group ( P = 0.395). Survival analysis showed no statistically significant difference in DFS [5-year DFS rate: 33.6% vs. 73.2%, P = 0.118] between the two groups. The 5-year OS rates for RLA group versus TLA group were 58.3% vs. 45.5% ( P=0.485). Conclusions:For localized (stage Ⅰ/Ⅱ) ACC, both RLA and TLA seem safe and feasible, based on the similar long-term oncological prognosis. However, compared with TLA, RLA has the advantage of shorter operation time and postoperative drainage tube removal time. Due to the small number of cases included in this study, further multi-center, large-sample studies are required to demonstrate clear benefit of one surgical approach in the future.
