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.

Traditional Chinese medicine contains a variety of volatile components （VOCs） such as terpenes and aliphatics, which have significant pharmacological activities, and are commonly analyzed by gas chromatography （GC） and gas chromatography-mass spectrometry （GC-MS）. Although the separation ability is strong, the samples need to be pre-treated and the analysis time is long. In recent years, the combination of GC and ion migration spectrometry （IMS） has been widely used in the academic community. The combination of high separation ability of GC and rapid reaction ability of IMS has the advantages of no sample pretreatment, fast analysis time, low detection limit and simple operation. It is increasingly used in traditional Chinese medicine research. The working principle of GC-IMS was introduced, the application in VOCs research of traditional Chinese medicine was summarized, and the future development direction was prospected in this paper.

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.

BackgroundRehabilitation for schizophrenia typically relies on pharmacological interventions， yet their efficacy in improving social function and quality of life remains limited. In recent years， non-pharmacological approaches have shown promise in enhancing rehabilitation outcomes. However， research on the effectiveness of psychomotor therapy specifically for young and middle-aged schizophrenic inpatients is limited. ObjectiveTo explore the effects of psychomotor therapy on the rehabilitation of young and middle-aged schizophrenic inpatients， and to provide a reference for treatment strategies. MethodsA total of 104 young and middle-aged schizophrenic inpatients who met the International Classification of Diseases，tenth edition （ICD-10） diagnostic criteria and hospitalized in the Fourth People's Hospital of Wuhu from June 2021 to June 2022 were selected. Patients were randomly divided into two groups of 52 each using random number table method. Both groups received treatment with risperidone tablets （2~4 mg/d） ， along with routine nursing care. Additionally， the research group received an extra 45~55 minutes of psychomotor therapy 2~3 times per week for 12 weeks. The control group received the same psychomotor therapy after the study. Positive and Negative Symptom Scale （PANSS）， Scales of Social-skills for Psychiatric Inpatient （SSPI） and Insight and Treatment Attitude Questionnaire （ITAQ） were used to assess the patients before the intervention and at 4^th， 8^th and 12^th week after the intervention. ResultsThe main effects of intervention at different time points for PANSS positive symptoms， negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score were all statistically significant （F=33.989， 204.245， 82.817， 279.596， 26.144， 7.463， P<0.01）. Furthermore， statistically significant between-group differences were observed in PANSS negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score （F=30.053， 5.306， 33.417， 33.013， 18.608， P<0.05 or 0.01）. Moreover， the interaction effect of time and group were statistically significant for PANSS positive symptoms， negative symptoms and general psychopathology subscale score， PANSS total score and SSPI score （F=3.472， 9.798， 3.843， 14.390， 20.661， P<0.05 or 0.01）. After 12 weeks of intervention， the research group exhibited statistically significantly lower PANSS total score and subscale scores compared with baseline （P<0.01）， while their SSPI total score was significantly higher than that of control group（P<0.01）. Additionally， compared with the control group， the research group had statistically significantly lower PANSS total score and subscale scores ， while their SSPI score was statistically significantly higher than those of control group（P<0.01）. ConclusionPsychomotor therapy may contribute to the improvement of the psychiatric symptoms and social function in young and middle-aged inpatients with schizophrenia， enhancing their rehabilitation outcomes. ［Funded by Health Commission Scientific Research Project of Wuhu （number， WHWJ2021y073）］

Objective     To explore the evolving strategies and compare perioperative and long-term outcomes of tricuspid valve replacement (TVR) in recent 20 years in our hospital. Methods    Between 1998 and 2018, the clinical data of 608 patients who underwent TVR at the Department of Cardiac Surgery, Guangdong Provincial People’s Hospital were retrospectively analyzed. There were 201 males and 407 females, with a median age of 47.0 (36.0, 57.0) years. Patients were divided into a biological tricuspid valve (BTV, n=427) group and a mechanical tricuspid valve (MTV, n=181) group. Propensity score matching was used to balance the baseline difference. Surgical strategy evolving, postoperative and long-term outcomes were analyzed between the two groups. Results    Since 2008, the usage ratio of biological valves was significantly higher than that of mechanical valves. Seventy-nine (13.0%) patients died in hospital after TVR. Before propensity score matching, the postoperative mortality of the BTV group was higher than that of the MTV group (15.2% vs. 7.7%, P=0.012), and there was no statistical difference between the two groups after matching (10.4% vs. 7.2%, P=0.372). The duration of postoperative ventilator support in the BTV group was longer than that in the MTV group [22.0 (15.0, 37.0) h vs. 19.0 (11.0, 27.0) h, P=0.003], and the incidence of postoperative dialysis and re-thoracotomy exploring for bleeding was higher in the BTV group (8.9 % vs. 2.8%, 9.4% vs. 6.6%, respectively). However, there was no statistical difference in mortality after matching. The median follow-up time of discharged patients was 101.0 (65.0, 147.0) months, ranged from 1 to 265 months, and the follow-up rate was 82.2%. During the follow-up period, there were 101 deaths (19.1%) of whom 68 were from the BTV group and 33 from the MTV group. The survival rates at 1 year, 5 years, 10 years, 15 years and 20 years of all patients were 85.0% (95%CI 82.2-87.9), 78.9% (95%CI 75.7-82.4), 71.1% (95%CI 67.3-75.3), 59.7% (95%CI 54.2-65.6) and 51.7% (95%CI 43.3-60.7), and there was no statistical difference between the two groups after matching (P=0.46). The median time of tricuspid valve failure was 84.0 (54.0-111.0) months. Conclusion    TVR is associated with high perioperative risks. There is no statistical difference in early mortality and long-term survival between biological and mechanical valve, while patients with mechanical valve has higher risk of re-operation for valve failure. Therefore, the type of prosthetic valve can be selected according to the patients' age, physical condition and the doctors’ experience.

Objective:To explore the curative efficacy of nerve root sheath plasty under microscope in treatment of patients with Tarlov cysts.Methods:A total of 41 patients with symptomatic Tarlov cysts, admitted to our hospital from March 2016 to December 2019, were collected; these patients received surgical treatment by nerve root sheath plasty under microscope and neuroelectrophysiological monitoring. The microsurgical efficacy was evaluated by changes of pain visual analogue scale (VAS) scores and lumbar Oswestry dysfunction index (ODI) before and one week, 3 months, and 6 (or 12) months after surgery.Results:The VAS scores and lumbar ODI of 41 patients one week, 3 months, and 6 (or 12) months after surgery were significantly reduced as compared with those before surgery, and presented a gradually decreased trend, with statistically significant differences between each time point ( P<0.05). The median of improvement rate of lumbar ODI was 72.7% (58.9%, 79.7%): curative effect was excellent in 19 patients (improvement rate of lumbar ODI>75%), good in 14 patients (51%≤improvement rate of lumbar ODI≤75%), passable in 3 patients (26%≤improvement rate of lumbar ODI≤50%), and poor in 5 patients (improvement rate of lumbar ODI≤25%), enjoying rate of excellent and good curative effect as 80.5% (33/41). Postoperative cerebrospinal fluid leakage occurred in two patients without infection. Cyst recurrence occurred in one patient on the 3 rd d of surgery due to loosening of the suture of the access hole, and no recurrence occurred after the second surgery. Conclusion:The compression of Tarlov cysts on nerve root can be safely and effectively relieved by nerve root sheath plasty under microscope and neuroelectrophysiological monitoring; the symptom relief rate is high and it is not easy to recur.

Objective: To study serum zinc level in pregnancy and umbilical cord blood and their association with newborn birth weight. Methods: Pregnant women accepting obstetric examination in Ma'anshan Maternal and Child Care Center were recruited from May 2013 to September 2014. The follow up was conducted during their first, second and third trimesters of pregnancy and the self-designed questionnaire was used to collect information of social and demographic characteristics. Blood samples in the first, second pregnancy period and umbilical cord blood samples were collected and serum concentrations of zinc were assayed. 3 239 mother-infant entered the final analysis. We divided serum zinc level into low (<P₂₅), medium (P₂₅-P₇₅) and high (>P₇₅) groups according to their exposure concentrations at each trimesters. Non-conditional multivariate logistic regression model was conducted to evaluate the association between serum zinc level in first, second trimesters of pregnancy and umbilical cord blood with small for gestational age (SGA) and large for gestational age (LGA). Results: Serum zinc level in P₅₀ (P₂₅-P₇₅) during the first, second trimesters and cord blood were 1 016.18 (907.09-1 145.60), 813.36 (732.47-897.89) and 903.44 (808.71-1 015.64) μg/L, respectively. The prevalence of zinc deficiency during the first, second trimesters and cord blood were 1.5% (44/2 957), 15.9% (492/3 087) and 6.5% (176/2 707), respectively. The prevalence of total SGA and LGA were 9.7% (313/3 239) and 16.5% (536/3 239), respectively. Compared to high-level serum zinc group, the risk of SGA (OR (95%CI) in low-level serum zinc group during first trimesters was 1.51 (1.05-2.19)). Serum zinc level among second pregnancy period and umbilical cord blood had no statistically significant effect on SGA and LGA (both P values >0.05). Conclusion Zinc nutritional status of pregnant women in Ma'anshan city was at a good level. The low serum zinc level in first trimester increased the risk of SGA.
