Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P＞0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.

AIM: To conduct a CiteSpace-based visualization analysis of the literature on traditional Chinese medicine(TCM)treatment of diabetic retinopathy(DR)from January 2014 to January 2024.METHODS: The literatures were retrieved from the China National Knowledge Infrastructure(CNKI)database. Co-occurrence, clustering, and emergence analyses of annual publications, authors, research institutions, and keywords were performed using Note Express and CiteSpace software to generate knowledge graph.RESULTS: A total of 643 Chinese-language articles were included. The annual publication trend was characterized by fluctuations. The primary research institutions were Liaoning University of Traditional Chinese Medical and Eye Hospital China Academy of Chinese Medical Sciences. Twenty high-frequency keywords were identified, including diabetes, TCM, and review, along with emergent terms such as Qiming granules and data mining. The research focus in 2014 was on exploring therapeutic methods and the efficacy of proprietary Chinese medicines. From 2016 to 2018, the research perspective expanded to include symptoms and multi-factorial analysis. Between 2018 and 2020, there was an in-depth investigation into evidence types and disease stages. After 2019, the emphasis shifted towards TCM-specific therapies and patient-centered concepts. From 2022 to 2024, innovation in research methods and the theory of TCM collaterals theory emerged as new hotspots.CONCLUSION: The research on TCM treatment for DR is still in an ascending phase. The primary research hotspot currently centers on Qiming granules. Future trends are likely to focus on the efficacy and mechanisms of action. The combined application of different therapies and long-term follow-up experimental research could provide a more robust basis for evidence-based medicine, unearth the potential of TCM, and promote its development in the prevention and treatment of DR.

Diabetes retinopathy (DR) is a blinding ocular complication of diabetes, and its pathological mechanism is complex. The damage to the retinal neurovascular unit (NVU) and the imbalance of its coupling mechanism are important pathological foundations. Autophagy plays an important role in the progression of DR. Oxidative stress, endoplasmic reticulum stress, hypoxia, and competitive endogenous RNA regulatory networks can affect the occurrence of autophagy, and autophagy induced cell death is crucial in NVU dysfunction. Retinal neurocyte are non-renewable cells, and adaptive autophagy targeting neuronal cells may provide a new direction for early vision rescue in patients with DR. It is necessary that exploring the possible autophagy interrelationships between ganglion cells, glial cells, and vascular constituent cells, searching for targeted specific cell autophagy inhibitors or activators, and exploring the impact of autophagy on the NVU complex more comprehensively at the overall level. Adopting different autophagy intervention methods at different stages of DR may be one promising research directions for future DR.

Objective To evaluate early outcomes of transthoracic pulmonary valve implantation for the treatment of moderate and severe pulmonary regurgitation by using homemade self-expanding valve (SalusTM). Methods Patients with severe pulmonary regurgitation who underwent transthoracic pulmonary valve implantation in Guangdong Provincial People’s Hospital from September 2, 2021 to November 25, 2022 were prospectively enrolled. The early postoperative complications and improvement of valve and heart function were summarized and analyzed. Results A total of 25 patients were enrolled, including 16 males and 9 females, with an average age of 24.5±1.5 years and an average weight of 57.0±3.0 kg. The mean systolic diameters of the bifurcation near the main pulmonary artery, the stenosis of the middle segment of the aorta and near the valve of the right ventricular outflow tract of the patients were 31.8±7.4 mm, 30.6±5.9 mm and 38.4±8.0 mm, respectively. All patients were successfully implanted with valves, and there were no serious complications such as death, coronary compression, stent fracture, valve displacement and infective endocarditis in the early postoperative period. The indexed left atrial longitudinal diameter, indexed right atrial longitudinal diameter, and indexed right ventricular outflow tract anteroposterior diameter decreased significantly after the operation. The degree of tricuspid and pulmonary valve regurgitation and the indexed regurgitation area decreased significantly. The above differences were statistically significant (P<0.05). Conclusion The early outcomes of transthoracic pulmonary valve implantation with homemade self-expanding pulmonary valve (SalusTM) in the treatment of severe pulmonary regurgitation is relatively good, and the long-term outcomes need to be verified by the long-term follow-up studies with large samples.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Pathological dry skin is a disturbing and intractable healthcare burden,characterized by epithelial hy-perplasia and severe itch.Atopic dermatitis(AD)and psoriasis models with complications of dry skin have been studied using single-cell RNA sequencing(scRNA-seq).However,scRNA-seq analysis of the dry skin mouse model(acetone/ether/water(AEW)-treated model)is still lacking.Here,we used scRNA-seq and in situ hybridization to identify a novel proliferative basal cell(PBC)state that exclusively expresses transcription factor CUT-like homeobox 1(Cux1).Further in vitro study demonstrated that Cux1 is vital for keratinocyte proliferation by regulating a series of cyclin-dependent kinases(CDKs)and cyclins.Clinically,Cux1+PBCs were increased in patients with psoriasis,suggesting that Cux1+ PBCs play an important part in epidermal hyperplasia.This study presents a systematic knowledge of the tran-scriptomic changes in a chronic dry skin mouse model,as well as a potential therapeutic target against dry skin-related dermatoses.

Objective:To observe the efficacy and adverse reactions of fractional radiofrequency (FRF) in the treatment of facial acne scars.Methods:Fifty-seven patients with facial acne depressed scars were enrolled with the nature of Dreno scars as the diagnostic criteria. They were treated with lattice radiofrequency. The treatment heads were arranged in a matrix with a treatment area of 1.2 cm ×1.2 cm, an energy density of 80-100 mJ/pin, and an interval of five-seven once a week. And they were followed up and evaluated for the clinical efficacy and adverse reactions 6 months after the last treatment. Scoring was carried out according to the ECCA weight scores, and the efficacy judged according to complete improvement, significant improvement, moderate improvement, and mild improvement.Results:After 3 times of fractional radiofrequency treatment of 57 patients, the effective rate was 44 cases, accounting for 77.2%; the ECCA weight scores before and after treatment were 65.9±25.0 and 47.7±20.2, respectively; the difference was statistically significant ( t=13.92, P<0.001); At the same time of improvement, 32 cases of patients' complexion, fineness of pores, and skin elasticity had been improved to varying degrees, and patient satisfaction was high. Adverse reactions were mainly mild burning sensation, erythema and edema, and some patients had pale yellow exudate, etc, which could be relieved in 5-7 days. Conclusions:Fractional radiofrequency treatment of facial acne scars is safe and effective, with short recovery period, few adverse reactions and high patient satisfaction.

Objective:To compare efficacy and safety of 308-nm SQ light-emitting diode (LED) light versus 308-nm excimer light in the treatment of facial vitiligo.Methods:Patients with stable facial vitiligo were retrospectively collected from Department of Physical Therapy, Hospital of Dermatology, Chinese Academy of Medical Sciences from June 2018 to June 2020, who received treatment with 308-nm SQ LED light (LED group) or 308-nm excimer light (excimer light group). The treatment was performed once or twice a week, and patients who had received more than 8 sessions of treatment were included in the analysis of efficacy and safety. Statistical analysis was carried out by using chi-square test.Results:Totally, 68 patients with 90 lesions were enrolled into the LED group, including 36 males and 32 females, aged 25.01 ± 13.37 years; 20 patients with 28 lesions were enrolled into the excimer light group, including 13 males and 7 females, aged 27.15 ± 14.30 years. After 8 and 16 sessions of treatment, there was no significant difference in the response rate between the LED group (23.33%, 46.67%, respectively) and excimer light group (14.29%, 46.43%, χ2 = 1.05, < 0.001, respectively, both P > 0.05). During the treatment, 36 (52.94%) patients in the LED group developed persistent erythema, 17 (85%) in the excimer light group developed persistent erythema or blisters. The incidence of adverse reactions was significantly lower in the LED group than in the excimer light group ( χ2 = 16.43, P < 0.001) . Conclusion:Compared with the 308-nm excimer light, the 308-nm SQ LED light showed similar effect but higher safety for the treatment of facial vitiligo.

Objective:To establish and validate a predictive model for treatment failure of peritoneal dialysis-related peritonitis(PDAP)in elderly patients.Methods:Clinical data of peritoneal dialysis(PD)patients who were followed up from January 1, 2013 to December 31, 2019 at four Grade A tertiary hospitals in Jilin Province were collected.A total of 362 elderly patients with PDAP were eventually included as study subjects.Subjects recruited from 2013 to 2017 were used for model construction and the logistic regression model was used to screen risk factors for treatment failure of PDAP in elderly patients.A nomogarm was constructed to predict treatment failure of secondary PDAP using R language.The receiver operating curve(ROC)and calibration curve were used to evaluate discrimination accuracy of the model.Subjects from 2018 to 2019 were used as the cohort for validation of discrimination accuracy of the model.Results:Of 258 PDAP patients in the modeling cohort, 29 experienced treatment failure, including 15 PDAP-related deaths and 14 cases requiring catheter removal.The multivariate logistic regression model showed that types of pathogens( OR=8.849, 95% CI: 1.656-47.269, P=0.011), long dialysis age( OR=1.023, 95% CI: 1.005-1.042, P=0.013), pre-hospitalization antibiotic treatment( OR=5.123, 95% CI: 1.338-19.610, P=0.017), and dialysate white blood cell count on day 5>100×10 6/L( OR=7.085, 95% CI: 2.162-23.217, P=0.001)were independent risk factors for treatment failure of PDAP in elderly patients.For the nomogarm predictive model, the areas under the ROC curve(AUC)in the modeling cohort and the validation cohort were 0.818(95% CI: 0.735-0.902)and 0.762(95% CI: 0.656-0.889), respectively, and the calibration curves were close to a straight line with a slope of 1. Conclusions:Our nomogram predictive model based on types of pathogens, months of dialysis, pre-hospital admission antibiotic treatment, and dialysate white blood cell count on day 5 has demonstrated satisfactory discrimination accuracy for treatment failure of PDAP in elderly patients.

Objective    To characterize surgical outcomes of supra-cardiac total anomalous pulmonary venous connection (TAPVC), investigate risk factors for postoperative death, and explore informed LASSO machine learning methods to solve "small sample size problem" in research of rare congenital heart diseases. Methods    A retrospective analysis of 241 patients with supra-cardiac TAPVC who underwent surgical repair in Guangdong Provincial People's Hospital from 2009 to 2019 was conducted, including 179 males and 62 females with a median surgical age of 71 (33, 232) d. Detailed clinical data of the postoperative death-related factors were extracted. Univariable Cox proportional hazard models were used to initially screen potential risk factors for postoperative death. Factors with P鈮?.05 were retained. To solve the limitation of small sample size and the "P>n" problem, we proposed a novel LASSO method for conducting multivariable Cox regression analysis that was capable of bringing in findings of related studies to improve analysis power and to reduce false-negative findings. Results 聽 聽Univariable Cox analyses showed several potential clinical risk factors, among which highly significant factors (P<0.001) included: surgical weight鈮?.5 kg (HR=16.00), main pulmonary artery diameter (HR=0.78), prolonged cardiopulmonary bypass time (HR=1.21), aortic block time (HR=1.28), and postoperative ventilator-assisted time (HR=1.13/d). LASSO multivariable analysis revealed that independent risk factors for postoperative death included cardiopulmonary bypass time (aHR=1.308/30 min), age (aHR=0.898), postoperative ventilator-assisted time (aHR=1.023/d), weight鈮?.5 kg (aHR=2.545), right vertical venous return (aHR=1.977), preoperative pulmonary venous obstruction (aHR=1.633) and emergency surgery (aHR=1.383). Conclusion 聽 聽Our proposed informed LASSO method can use previous studies' results to improve the power of analysis and effectively solve the "P>n" and small sample size limitation. Cardiopulmonary bypass time, surgical age, postoperative ventilator-assisted time, weight, right vertical venous return, preoperative pulmonary venous obstruction, and emergency surgery are risk factors for postoperative death of supra-cardiac TAPVC.
