Background: Diabetic macrovascular and microvascular complications often coexist and may share similar risk factors and pathological pathways. We aimed to investigate whether 10-year atherosclerotic cardiovascular disease (ASCVD) risk, which is commonly assessed in diabetes management, can predict incident diabetic nephropathy (DN) and retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Methods: This prospective cohort study enrolled 2,891 patients with clinically diagnosed T2DM who were free of ASCVD, nephropathy, or retinopathy at baseline in the Guangzhou (2017–2022) and Shaoguan (2019–2021) Diabetic Eye Study in southern China. The 10-year ASCVD risk was calculated by the Prediction for ASCVD Risk in China (China-PAR) equations. Multivariable- adjusted Cox proportional hazard models were developed to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). The area under the receiver operating characteristic curve (AUC) was used to evaluate predictive capability. Results: During follow-up, a total of 171 cases of DN and 532 cases of DR were documented. Each 1% increment in 10-year ASCVD risk was associated with increased risk of DN (pooled HR, 1.122; 95% CI, 1.094 to 1.150) but not DR (pooled HR, 0.996; 95% CI, 0.979 to 1.013). The model demonstrated acceptable performance in predicting new-onset DN (pooled AUC, 0.670; 95% CI, 0.628 to 0.715). These results were consistent across cohorts and subgroups, with the association appearing to be more pronounced in women. Conclusion Ten-year ASCVD risk predicts incident DN but not DR in our study population with T2DM. Regular monitoring of ASCVD risk in routine diabetes practice may add to the ability to enhance population-based prevention for both macrovascular and microvascular diseases, particularly among women.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

While lobectomy is the standard surgical procedure for early-stage non-small cell lung cancer (NSCLC), sublobectomy (segmentectomy/wedge resection) has been gaining progress in early-stage peripheral NSCLC in recent years because it preserves more lung parenchyma and has the advantages of good postoperative lung function, relatively less trauma, and faster recovery. However, there has been a lack of standardized randomized clinical trials to study the survival benefits of sublobectomy. The results of a high-profile study from the USA, CALGB140503, have been the subject of intense industry debate since its presentation at the 2022 World Conference on Lung Cancer (IASLC WCLC 2022). The study, which was published in The New England Journal of Medicine on February 9, 2023, was designed to investigate whether sublobectomy was not inferior to lobectomy in terms of survival in patients with early-stage peripheral NSCLC (tumor diameter≤2 cm). The results showed that sublobectomy was not worse than lobectomy for survival in patients with T1aN0M0 peripheral NSCLC with tumor diameter≤2 cm and pathologically confirmed negative hilar and mediastinal lymph nodes. Sublobectomy, including anatomical segmentectomy and wedge resection is an effective NSCLC treatment. The results of this study provide strong evidence for the improved outcomes of sublobectomy in terms of lung function protection and are expected to promote the further use of sublobectomy. However, given the limitations of this study, whether sublobectomy, especially wedge resection, can become a standard procedure still needs to be explored. This paper presents an interpretation of this study and we invite experts in the field to discuss its usefulness in guiding clinical practice and summarise its limitations.

Objective:To handle blood loss during liposuction for secondary lymphedema of lower extremities in patients with secondary lymphedema.Methods:The clinical data of 214 patients with secondary lymphedema of the lower extremities undergoing liposuction at Department of Lymphatic Surgery, Capital Medical University Affliated Beijing Shijitan Hospital from Sep 2018 to Jan 2020 were retrospectively analyzed.Results:There were 209 females and 5 males. The average fat aspiration was (2 934.58±1 114.83) ml, the average blood loss was (986.04±425.16) ml, 117 patients were transfused, including autologous transfusion in 90 patients, 15 patients received allogeneic blood, and 12 patients received autologous plus allogeneic blood. The disease phase, operative time and fat aspiration were positively correlated with blood loss, and were independent risk factors affecting blood loss.Conclusion:Liposuction for secondary lymphedema of the lower extremity is an important factor leading to anemia.

Objective:To explore the blood loss during liposuction for secondary lymphedema of the lower extremities and to analyze the risk factors that influence the blood loss.Methods:Retrospective analysis of the clinical data of patients with secondary lymphedema of lower extremities at the Department of Lymphatic Surgery, Capital Medical University Affiliated Beijing Shijitan Hospital from January 2019 to December 2019. The following clinical indicators were correlated with the amount of blood loss, including age, body mass, body mass index (BMI), primary disease, hypertension, radiotherapy history, chemotherapy history, erysipelas history, affected extremity, duration of swelling, duration of primary disease, International Society of Lymphology(ISL) stage, time of operation, infiltration volume, fat aspiration, blood-tinged fluid solution, volume difference, preoperative hemoglobin. Pearson analysis was used for the univariate analysis of continuous variables, Spearman analysis was used for the univariate analysis of classified variables, multiple linear regression was used for multivariate analysis of continuous variables, and Logistic regression was used for the multivariate analysis of classified variables.Results:174 patients were enrolled, all females with a median age of 55 years. Univariate analysis showed that the age( r=0.17, P=0.026), the body mass( r=0.37, P<0.001), BMI( r=0.29, P<0.001), hypertension( r=0.25, P=0.001), the ISL stage( r=0.40, P<0.001), operative time( r=0.44, P<0.001), infiltration volume( r=0.53, P<0.001), fat aspiration( r=0.36, P<0.001), blood-tinged fluid solution( r=0.61, P<0.001) and volume difference( r=0.63, P<0.001) were associated with the blood loss. There was no correlation between primary disease, radiotherapy history, chemotherapy history, erysipelas history, affected extremity, duration of swelling, duration of primary disease, preoperative hemoglobin and blood loss( P>0.05). Multivariate analysis showed that hypertension ( r=0.14, P=0.012), operative time ( r=0.15, P=0.019) and volume difference ( r=0.30, P=0.001) were independent risk factors affecting blood loss. Conclusion:Hypertension, operative time and volume difference are the risk factors of blood loss during liposuction for secondary lymphedema of the lower extremities.

Objective:To explore the application of laparoscopic training in the standardized residency training of pediatric general surgery.Methods:A total of 36 rotating residents who received the standardized residency training in the department of pediatric general surgery of Shenzhen Children's Hospital from January 2017 to December 2019 were selected for laparoscopic training. The training content includes the study and training of laparoscopic theory knowledge, laparoscopic surgery video, skills operation of simulated operating system. Assessment was conducted before and after the training, and statistical analysis was performed to compare the difference of scores before and after the training. The self-evaluation of resident's learning efficiency and the satisfaction with teachers were investigated by questionnaires. SPSS 20.0 was used for paired t-test. Results:After receiving the standardized residency training of pediatric general surgery, the theoretical knowledge and cognition of the application on pediatric general laparoscopic surgery were significantly improved among the 36 residents. The time that the skills spent in vitro simulation box during the simulated operation training was significantly reduced after training, with a statistically significant difference ( P < 0.05). According to the questionnaire survey, resident's satisfaction with self-evaluation of learning efficiency was 97.22% (35/36), their satisfaction with teachers was 94.44% (34/36), and their satisfaction with teaching curriculum was 100.00% (36/36). Conclusion:Laparoscopic training can effectively improve the clinical practice ability of pediatric general surgery residents, which is worthy of promotion.
