The pathogenesis of diabetic cardiomyopathy(DCM)is complex.Autophagy plays a pivotal role in the development of DCM,and whether its level is stable or not is closely related to the development of the course of DCM.Numerous active components found in traditional Chinese medicines and compound formulations have demonstrated the ability to modulate autophagy levels.These interventions occur through various mechanisms,such as hypoglycemic,anti-apoptotic,anti-inflammatory,and anti-oxidative stress pathways.By mitigating autophagy-induced myocardial damage,enhancing cardiac function,and slowing the progression of DCM,these compounds offer promising avenues for DCM management.This paper aims to consolidate and present research findings from the last 5 years.Our goal is to provide valuable insights and references for the research,development,and clinical application of Chinese medicine in the context of combating DCM.

Objective:To evaluate the viability and clinical effect of polyfoliate anterolateral thigh perforator flap (ALTPF) in reconstruction of large soft tissue defect around ankle.Methods:From June 2019 to October 2022, large soft tissue defects around ankle of 11 patients were reconstructed with ALTPF in the Department of Orthopaedics of the First Affiliated Hospital of Nanchang University. The causes of injury were traffic accident in 8 patients and heavy objects in 3 patients. All wounds were large defects (15.0 cm×14.0 cm-30.0 cm×20.0 cm) and combined with various degrees of infection. Intraoperatively, polyfoliate ALTPFs sized 16.0 cm×14.5 cm-23.0 cm×18.5 cm were used in reconstruction of the defects. Deep dead spaces were filled with antibiotic bone cement, and direct suture was performed to close the donor sites or by skin grafting repair. Postoperative follow-ups were scheduled at 1, 3 and 6 months, and 6 monthly thereafter at outpatient clinics and via telephone interviews. The appearance and colour of the flaps and healing of donor sites were recorded together with evaluation of the recovery of ankle motor function according to the ankle-hindfoot rating scale of American Orthopaedic Foot and Ankle Society (AOFAS).Results:All flaps survived. No haematoma or secondary infection occurred at the recipient site after surgery. All donor sites healed primarily. One patient had venous occlusion at the distal end of the polyfoliate ALTPF. The flap survived completely at 1 week after distal venous bloodletting. Postoperative follow-ups lasted 6-24 (15.27±5.21) months. All flaps had good blood supply with satisfactory appearance, similar colour and texture to the recipient sites, and without obvious bloat nor ulceration. Only a linear scar or few skin graft scar was left at the flap donor sites in concealed locations. The mean AOFAS ankle-hindfoot score was (88.36±10.21) point. There were 6 cases of excellent, 4 cases of good, and 1 case of fair.Conclusion:A polyfoliate ALTPF is an ideal flap for reconstruction of soft tissue defects around ankle by converting the length of a flap to the width.

Purpose::Cerebral edema (CE) is the main secondary injury following traumatic brain injury (TBI) caused by road traffic accidents (RTAs). It is challenging to be predicted timely. In this study, we aimed to develop a prediction model for CE by identifying its risk factors and comparing the timing of edema occurrence in TBI patients with varying levels of injuries.Methods::This case-control study included 218 patients with TBI caused by RTAs. The cohort was divided into CE and non-CE groups, according to CT results within 7 days. Demographic data, imaging data, and clinical data were collected and analyzed. Quantitative variables that follow normal distribution were presented as mean ± standard deviation, those that do not follow normal distribution were presented as median (Q 1, Q 3). Categorical variables were expressed as percentages. The Chi-square test and logistic regression analysis were used to identify risk factors for CE. Logistic curve fitting was performed to predict the time to secondary CE in TBI patients with different levels of injuries. The efficacy of the model was evaluated using the receiver operator characteristic curve. Results::According to the study, almost half (47.3%) of the patients were found to have CE. The risk factors associated with CE were bilateral frontal lobe contusion, unilateral frontal lobe contusion, cerebral contusion, subarachnoid hemorrhage, and abbreviated injury scale (AIS). The odds ratio values for these factors were 7.27 (95% confidence interval ( CI): 2.08 -25.42, p = 0.002), 2.85 (95% CI: 1.11 -7.31, p = 0.030), 2.62 (95% CI: 1.12 -6.13, p = 0.027), 2.44 (95% CI: 1.25 -4.76, p = 0.009), and 1.5 (95% CI: 1.10 -2.04, p = 0.009), respectively. We also observed that patients with mild/moderate TBI (AIS ≤ 3) had a 50% probability of developing CE 19.7 h after injury (χ 2= 13.82, adjusted R2 = 0.51), while patients with severe TBI (AIS > 3) developed CE after 12.5 h (χ 2= 18.48, adjusted R2 = 0.54). Finally, we conducted a receiver operator characteristic curve analysis of CE time, which showed an area under the curve of 0.744 and 0.672 for severe and mild/moderate TBI, respectively. Conclusion::Our study found that the onset of CE in individuals with TBI resulting from RTAs was correlated with the severity of the injury. Specifically, those with more severe injuries experienced an earlier onset of CE. These findings suggest that there is a critical time window for clinical intervention in cases of CE secondary to TBI.

Objective:To investigate the selection of the modality of transperineal surgery and its effect in the treatment of pel-vic fracture-induced posterior urethral atresia(PUA).Methods:This study included 116 cases of PUA caused by pelvic fractures treated in our hospital from January 2012 to December 2021.We used transperineal resection of the urethral stricture and end-to-end u-rethral anastomosis(EEUA)as the first choice in the treatment of 79 cases.For the patients with the urethral atresia segment longer than 3 cm and evident urethral involution tension,we incised the penile septum,separated and removed the muscle tendon and scar tis-sue attached to the lower border of the pubis,and anastomosed with 4-0 absorbable thread for 8 stitches.For the other 37 cases for which we were not sure of effective suture of the membrane due to obvious scarring of the proximal urethra,the remaining urethra shor-ter than 5 mm or incomplete urethral mucosa,we selected conventional urethral pull-through operation(UPTO).We followed up the patients for 3-24 months postoperatively.Results:The total success rate of surgery was 78.4%(91/116),81.1%(30/37)in the UPTO and 77.2%(61/79)in the EEUA group,significantly higher in the former than in the latter(P=0.05).The rate of post-operative dysuria was remarkably lower in the UPTO than in the EEUA group(13.5%[5/37]vs 16.5%[13/79],P=0.05),and so was that of surgical failure(5.4%[2/37]vs 6.3%[5/79],P=0.05).The main causes of postoperative dysuria in the EEUA group included restenosis resulting from incomplete scar resection and the two sides of the anastomosed urethral segment not being at the coaxial level,while those in the UPTO group included the formation of mucosal flaps in the pulled-through urethra,and re-scarring leading to stricture or the pulled-through urethra not being at the coaxial level.Among the 7 cases of surgical failure due to recurrence,1 refused reoperation and opted for cystostomy tube drainage,and the other 6 underwent EEUA again 6 months later.Conclusion:EEUA is preferred as the first-choice surgery for PUA,while UPTO remains an effective treatment option in hospitals with preliminary skills and less experience in the management of PUA.
