Objective To evaluate the impact of an integrated management mode of prenatal diagnosis-postnatal treatment for congenital heart disease (CHD) on perioperative and long-term outcomes of the arterial switch operation (ASO), and to analyze the efficacy of ASO in a single center. Methods This retrospective study analyzed the clinical data of 183 children who underwent ASO at Guangdong Provincial People’s Hospital from 2018 to 2024. The cohort included 106 (57.9%) patients of transposition of the great arteries with intact ventricular septum (TGA/IVS), 61 (33.3%) patients of transposition of the great arteries with ventricular septal defect (TGA/VSD), and 16 (8.7%) patients of Taussig-bing anomaly (TBA). Perioperative indicators were compared between 91 patients in the prenatal-postnatal integrated management group (an integrated group) and 92 patients in the traditional management group (a non-integrated group). Long-term survival and reoperation rates were analyzed using Kaplan-Meier curves. Results The overall perioperative mortality rate was 4.9% (9/183), showing a downward trend year by year. The primary cause of perioperative mortality was low cardiac output syndrome (LCOS), which occurred in 12 patients (6.6% incidence) with a mortality rate of 75.0%. The integrated group had a higher proportion of males (89.0% vs. 72.8%, P<0.05) and lower body weight [3.1 (2.7, 3.3) kg vs. 3.3 (3.0, 3.7) kg, P<0.05] compared to the non-integrated group. The age at surgery was significantly earlier in the integrated group [7 (3, 10) d vs. 14 (9, 48) d, P<0.05], and all children in the integrated group underwent ASO within the optimal surgical window (100.0% vs. 82.6%, P<0.05). Intraoperatively, cardiopulmonary bypass time [173 (150, 207) min vs. 186 (159, 237) min, P<0.05] and aortic cross-clamp time [100 (90, 117) min vs. 116 (97, 142) min, P<0.05] were significantly shorter in the integrated group. Although the integrated group had longer postoperative mechanical ventilation time [145 (98, 214) h vs. 116 (77, 147) h, P<0.05] and higher 48-hour maximum vasoactive inotropic score [15 (10, 21) points vs. 12 (8, 16) points, P<0.05], there was no statistically significant difference in the incidence of severe complications (LCOS, necrotizing enterocolitis, extracorporeal membrane oxygenation) or mortality rate (3.3% vs. 6.5%, P=0.51) between the two groups, despite earlier surgical intervention and a higher proportion of critically ill cases in the integrated group. The length of hospital stay in the emergency surgery group was significantly shorter than that in the elective surgery group [20 (15, 28) d vs. 25 (21, 30) d, P<0.05], suggesting that early surgery may be of potential benefit. A total of 163 patients were successfully followed up for a median of 4.7 years, with a 5-year survival rate of 95.1% and a freedom from reintervention survival rate of 95.1%. There were no late deaths, and the most common postoperative complication was pulmonary artery stenosis. Conclusion The integrated management model allowed critically ill children with lower body weights to safely undergo surgery, significantly optimizing the timing of surgery and shortening intraoperative times. The long-term risk of reoperation after ASO is primarily concentrated on pulmonary artery stenosis, necessitating long-term follow-up and monitoring.

With the rapid advancements in surgical and interventional therapies, over 90% of children with congenital heart disease can now survive into adulthood with appropriate treatment. As a rapidly expanding population, adult congenital heart disease (ACHD) patients often present with complex anatomical abnormalities and post-procedural complications, posing significant long-term management challenges for clinicians. The American College of Cardiology and American Heart Association jointly released the 2025 guidelines for the management of adult congenital heart disease, which represents a comprehensive and fundamental update following the inaugural 2008 edition. This new guideline not only integrates the latest evidence-based data but also marks a paradigm shift in ACHD management, from a disease-centered approach to a patient-centered lifelong continuum of care. This article aims to provide an interpretation of the guidelines from the perspective of a cardiac surgeon to provide references for the management of various disease subtypes.

ObjectiveTo evaluate the clinical efficacy and safety of Xiaozhen Formula （消疹方） in preventing skin toxicity induced by epidermal growth factor receptor inhibitors （EGFRIs） in patients with EGFR-mutant non-small cell lung cancer （NSCLC）. MethodsA randomized， double-blind， placebo-controlled， multicenter clinical study was conducted. A total of 120 patients with EGFR-mutant NSCLC from seven centers were enrolled and randomly assigned to a treatment group （60 cases） or a control group （60 cases）. On the basis of EGFRI-targeted therapy， patients in the treatment group received Xiaozhen Formula granules， whereas those in the control group received Xiaozhen Formula placebo granules， both at 10 g twice daily for 4 consecutive weeks. The primary outcomes were the grading of skin toxicity evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events （NCI-CTCAE） version 5.0 and the incidence of rash. Secondary outcomes included the time to onset and time to resolution of the highest-grade rash， the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 （EORTC QLQ-C30） scores， the Hospital Anxiety and Depression Scale （HADS） scores， and disease control rate， together with safety assessments. ResultsBased on the full analysis set （FAS）， the incidence of skin toxicity in the treatment group was 18.33% （11/60）， significantly lower than 45.00% （27/60） in the control group （P＜0.01）， with the highest severity of skin toxicity in both groups was grade 2. Among patients who developed rash， the resolution rate in the treatment group was 90.91% （10/11）， higher than that 33.33% （9/27） in the control group. The median time to resolution was 15 days （95%CI： 8-17 days） in the treatment group and it was not reached in the control group； the distribution of time to resolution differed significantly between groups （P＜0.001）. After treatment， the treatment group had higher EORTC QLQ-C30 functional scale and global health status/quality-of-life scores， and lower symptom scale， single-item scores， as well as HADS-A， and HADS-D scores than the control group （P＜0.05）. In the FAS analysis， the disease control rate （DCR） was 85.0% （51/60） in the treatment group， lower than 100.0% （60/60） in the control group （P=0.003）， whereas no significant between-group difference was observed in the per-protocol set （PPS） analysis （P=0.464）. The incidence of adverse events did not differ significantly between the two groups （P＞0.05）， and no definite safety signals related to the investigational drug were observed. ConclusionXiaozhen Formula can reduce the incidence of EGFRI-induced skin toxicity， and improve the outcome of rash regression， the patients' quality of life and psychological status in EGFR-mutant NSCLC patients.

Objective::This study aimed to investigate the feasibility, efficacy, and safety of using a miniature mobile integrated cabin-theatre equipped with angiography and surgical operating room capabilities, and to explore its therapeutic scope, effectiveness, and operational mode.Methods::A miniature mobile integrated operating cabin-theatre was deployed across 15 hospitals in 15 cities or counties in China from April 2012 to November 2024. The interventions and outcomes of interventional and minimally invasive surgical procedures were prospectively observed and evaluated; perioperative complications were documented, and the stability, adaptability, and mobility of the integrated system were assessed.Results::A total of 133 procedures were successfully performed, 130 of which were interventional and 3 minimally invasive. The angiography machine showed good imaging performance without any equipment failures, loosening, or damage, with normal chamber unfolding. One patient experienced a fever the day after laparoscopy, while none of the other patients exhibited perioperative complications such as infection, surgical site bleeding/hematoma, or reperfusion arrhythmia. The instrument was easily manipulated, aligning with the needs of clinical intervention and surgery, and was perceived by patients as being a comfortable environment, with no psychological or other obvious discomfort.Conclusions::The miniature mobile integrated cabin-theatre, comprising an angiography machine and an operating room, allows interventional or minimally invasive surgical procedures to be performed smoothly and safely. It can also provide rapid and efficient on-site treatment of acute and critical illnesses across multiple body systems, including the cardiovascular, cerebrovascular, and gastrointestinal systems.

Objective To investigate the diagnostic efficacy of targeted biopsy(TB)combined with ipsilateral hemiglandular systematic biopsy(SB)of the dominant lesion,so as to explore a novel reduced-core biopsy strategy.Methods A retrospective analysis was conducted on the clinical data of 299 patients treated in our hospital during Sep.1,2022,and Feb.28,2023,who had a Prostate Imaging Reporting and Data System(PI-RADS)score ≥3 and underwent combined TB and SB.The dominant lesion was defined as the lesion with the highest PI-RADS score on multi-parametric magnetic resonance imaging(mpMRI);in cases of identical scores,the largest was designated as the dominant.SB was categorized as ipsilateral(ipsi-SB)or contralateral(contra-SB)to the dominant lesion.The consistency in detecting clinically significant prostate cancer(csPCa)was compared between TB with ipsi-SB(TB+ipsi-SB),TB with contra-SB(TB+contra-SB),and TB with SB(TB+SB).Subgroup analyses were performed based on PI-RADS score,prostate-specific antigen(PSA)level,prostate volume(PV),and mpMRI lesion distribution to evaluate csPCa detection rates across different variables.Results TB+ipsi-SB demonstrated comparable detection rate to TB+SB(46.2％vs.46.8％).The K values for TB+ipsi-SB and TB+contra-SB relative to TB+SB were 0.987(95％CI:0.969-1.000,P＜0.01)and 0.933(95％CI:0.892-0.974,P＜0.01),respectively.Across all subgroups,TB+ipsi-SB showed the highest agreement with TB+SB.Notably,in subgroups with PI-RADS 3 and 5,PSA＞0-20 ng/mL,PV＜25 mL,bilateral or multiple mpMRI lesions,TB+ipsi-SB achieved complete concordance with TB+SB in csPCa detection[K=1.000(95％CI:1.000-1.000),P＜0.01].Conclusion For patients with PI-RADS score ≥3,TB+ipsi-SB exhibits near-perfect consistency with TB+SB in csPCa detection while requiring fewer biopsy cores.TB+ipsi-SB represents a promising refinement of the TB+SB approach.

Objective:To explore the clinical value of autologous umbilical cord whole blood(UCB) priming of the cardiopulmonary bypass(CPB) circuit in neonatal cardiac surgery for congenital heart disease(CHD).Methods:This prospective non-randomized controlled trial included neonates undergoing CHD surgery at Guangdong Provincial People’s Hospital from August 2024 to January 2025. The experimental group used autologous UCB for CPB circuit priming, while the control group used adult allogeneic blood(AAB) priming when UCB was unavailable. Preoperative characteristics, intraoperative CPB and aortic cross-clamping(ACC) times, postoperative ICU stay duration, mechanical ventilation time, and hospitalization length were compared.Results:There were no significant differences in preoperative baseline characteristics between the two groups( P>0.05). At the end of surgery, red blood cell count(RBC), hemoglobin level(Hb), and creatine kinase(CK) showed no significant differences between the groups( P> 0.05). Additionally, perioperative left ventricular ejection fraction(LVEF) demonstrated no statistically significant variations( P>0.05). At surgery completion, the UCB group exhibited lower hematocrit(HCT) and higher blood lactic acid(Lac) levels but these differences resolved by 6 hours postoperatively( P>0.05). The UCB group had higher maximum vasoactive-inotropic scores(VISmax) within 48 hours and longer ICU stays, though total hospitalization and mechanical ventilation durations showed no significant differences( P>0.05). Conclusion:Autologous UCB priming reduces AAB requirements and has minimal impact on postoperative cardiac and pulmonary function recovery, or homeostasis., which is safe and feasible. This study provides evidence supporting the clinical application of UCB priming in CPB circuits.

Objective:To evaluate any effect of transcranial direct current stimulation (tDCS) on cognitive impairment after an ischemic stroke (IS) using tract-based spatial statistics (TBSS).Methods:Fifty-one patients with mild or more serious cognitive impairment after an IS were divided into an electrical stimulation group (26 cases) and a control group (25 cases) using a random number table. In addition to conventional rehabilitation treatment, the electrical stimulation group was given tDCS, while the control group was given sham tDCS for 15 days. Before and after the treatment, both groups were evaluated using the Mini-mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). Diffusion tensor imaging (DTI) was also performed. TBSS were computed for the differences in fractional anisotropy (FA) between the two groups before and after the treatment, and Pearson correlation analysis was applied to the pre-treatment and post-treatment FA differences within each group and the improvements in MMSE and MoCA scores.Results:After the treatment, the average MMSE and MoCA scores of both groups had improved significantly, but the improvement was significantly greater in the electrical stimulation group. After the treatment, the FA values among the electrical stimulation group had increased significantly in the bilateral genu of the corpus callosum, the bilateral inferior fronto-occipital fasciculus, the bilateral anterior thalamic radiation and the left superior longitudinal fasciculus. In the control group significant increases were recorded only in the left superior longitudinal fasciculus and the left anterior thalamic radiation. The FA change in the left superior longitudinal fasciculus of the electrical stimulation group was then positively correlated with the improvement in MMSE scores ( r=0.42), and that in the left anterior thalamic radiation was positively correlated with the improvement in MoCA scores ( r=0.45). Conclusions:tDCS can significantly improve the cognition of stroke survivors with cognitive impairment and promote the recovery of white matter fiber tracts. The FA values of the anterior thalamic radiation and the superior longitudinal fasciculus may be useful predictors and indicators of the recovery of cognitive function among such patients.

Alzheimer's disease(AD), a neurodegenerative disorder associated with aging, is the most prevalent form of dementia.As the aging population continues to expand, AD presents significant health and caregiving challenges for families and society, making it a pressing international public health concern.In recent years, numerous countries have implemented dementia prevention and treatment strategies that emphasize community-based comprehensive approaches.Currently, the community-based AD prevention and treatment model in China is still in the exploratory phase, with community efforts lacking organization.In alignment with China's action plan for advancing dementia prevention and treatment, and to achieve the strategic objective of "healthy aging, " this consensus is based on the principle of three-level prevention and is tailored to the characteristics of AD disease progression.It aims to develop a comprehensive prevention and treatment strategy for AD that is suitable for communities in China, providing technical guidance and support to establish a scientific basis for formulating community AD prevention and treatment models.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.
