Objective     To summarize the surgical treatment experience in neonates with coarctation of the aorta (CoA) and aortic arch hypoplasia (AAH). Methods     The neonates with CoA and AAH who underwent surgical treatment in the Department of Pediatric Cardiac Surgery of Guangdong Provincial People's Hospital from 2013 to 2020 were retrospectively enrolled. The postoperative complications, long-term survival rate, and freedom from aortic reobstruction were analyzed. Patients undergoing extended end-to-end anastomosis were allocated into an extended end-to-end group, those undergoing extended end-to-side anastomosis into an extended end-to-side group, and those undergoing pulmonary autograft patch aortoplasty into a patch aortoplasty group. Results     Finally 44 patients were  enrolled, including 37 males and 7 females, aged 5.00-30.00 (19.34±7.61) days and weighted 2.00-4.50 (3.30±0.60) kg. There were 19 patients of extended end-to-end anastomosis, 19 patients of extended end-to-side anastomosis, and 6 patients of pulmonary autograft patch aortoplasty. The mean values of the Z scores of the proximal, distal, and isthmus of the aortic arch were –2.91±1.52, –3.40±1.30, and –4.04±1.98, respectively. The mean follow-up time was 45.6±3.7 months. There were 2 early deaths and no late deaths. Aortic reobstruction occurred in 8 patients, and 3 patients underwent reoperation intervention. The 5-year rate of freedom from reobstruction was 78.8%. The Cox multivariable regression analysis showed that the related factors for postoperative reobstruction were the Z score of the preoperative proximal aortic arch (HR=0.152, 95%CI 0.038-0.601, P=0.007) and the postoperative left main bronchus compression (HR=15.261, 95%CI 1.104-210.978, P=0.042). Conclusion     Three surgical procedures for neonates with CoA and AAH are safe and effective, but the aortic reobstruction rate in long term is not low. The smaller Z score of the preoperative proximal aortic arch and the postoperative left main bronchus compression are risk factors for long-term aortic reobstruction.

To develop a caregiver parenting behavior scale for children aged 2 to 6 years, and to verify its reliability and validity. This study recruited 1 350 caregivers of children aged 2 to 6 years. The item discrimination analysis and exploratory factor analysis were used to analyze the structure, dimensions and items of the scale. Homogeneity reliability, split-half reliability and test-retest reliability were used to analyze the reliability of the scale. Content validity and construct validity were used to analyze the validity of the scale. The results showed that the final scale contained 7 dimensions and 45 items. Cronbach's α coefficient of the total scale was 0.945; the coefficient of split half was 0.899; the test-retest reliability analysis showed that the correlation coefficients between the two tests were 0.893 (total score), 0.854 (social), 0.832 (language), 0.871 (gross motor), 0.893 (fine motor), 0.862 (cognitive), 0.832 (self-care), and 0.872 (sensory). The content validity analysis was carried out by two rounds of expert argumentation using Delphi expert consultation method. The Kendall coefficient of the items score in two rounds of Delphi expert consultation was 0.813 (P<0.01). The structure validity analysis showed that there were significant correlations between each dimension and the total scale, also between each dimension of the scale, and the extracted average variance values of each dimension was greater than the correlation coefficients between this dimension and other dimensions. In conclusion, the reliability and validity of the scale are qualified. It can be used as a tool to evaluate and guide the parenting behavior of caregivers of children aged 2 to 6 years.

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.

Objective    To review the characteristics of patients who underwent atrioventricular septal defects (AVSD) repair with prosthetic valve ring implantation in our hospital, and to analyze the safety and effectiveness of this intervention. Methods    The clinical data of all patients diagnosed with AVSD who received surgery repair and prosthetic valve ring implantation from January 1, 2018 to July 12, 2020 in Guangdong Provincial People's Hospital were collected and analyzed. There were 22 patients with 9 males and 13 females at a median age of 35.00 (14.10, 53.00) years. There were 9 (40.9%) patients with prosthetic half or full rings placed on the left atrioventricular valve and 18 (81.8%) patients with prosthetic half or full rings placed on the right atrioventricular valve. Results    The median postoperative hospital stay was 7.00 (6.00, 8.80) d, and the postoperative mechanically assisted ventilation time was 11.00 (6.25, 19.00) h. There were 2 (9.1%) patients of moderate or higher postoperative atrioventricular valve regurgitation, 1 on the left and 1 on the right. There was one patient (4.5%) of the postoperative residual septal defect. There was no left ventricular inflow or outflow tract obstruction and no postoperative residual atrial septal defect during the follow-up of 152.00 (124.00, 1 030.00) d. Conclusion    Implantation of a prosthetic ring is safe and effective in patients with AVSD, and the structural strength of  the ring may be improved after the implantation. The physiological development of the AVSD annulus after prosthetic ring implantation and the results of long-term follow-up needs further attention.

AIM: To systematically evaluate the efficacy and safety of olopatadine combined with pranoprofen in the treatment of allergic conjunctivitis.METHODS: Using “olopatadine eye drops”, “pranoprofen eye drops” and “allergic conjunctivitis” as keywords, the controlled clinical trials of olopatadine combined with pranoprofen in the treatment of allergic conjunctivitis were searched from Embase, Cochrane library, PubMed, CNKI, Wanfang and VIP database, with an retrieval time from the establishment of the database to January 1, 2022; The Cochrane Risk of Bias Assessment Tool was used to assess the quality of the included studies, and the Egger's test was performed for publication bias of the included literatures. Meta-analysis was performed by using RevMan 5.3.RESULTS: A total of 24 eligible Chinese literatures were included, with 2 443 patients(2 547 eyes)in total. The test group was administrated olopatadine combined with pranoprofen, and the control group was treated with olopatadine monotherapy; The results of Meta-analysis showed that the clinical efficiency of the test group was better than that of the control group(OR=4.42, 95%CI:3.37-5.80,P<0.00001); There was no significant difference in the incidence of adverse reactions between the test group and the control group(OR=0.89, 95%CI: 0.45-1.75, P=0.73); Egger's test was conducted on the clinical efficiency and the incidence of adverse reactions, which showed that there was publication bias in the clinical efficiency, but the existed publication bias did not affected results through trim and fill method.CONCLUSIONS: The combination of olopatadine with pranoprofen may improve the clinical efficacy of allergic conjunctivitis. In the future, multicentered, randomized, double-blind studies can be conducted to improve the strength of the evidence.

Objective:This study aimed at analyzing risk factors associated with surgical outcomes of neonatal total anomalous pulmonary venous connection (TAPVC) in our center.Methods:A total of 105 neonates who underwent surgical repair for TAPVC from January 1st, 2009 to January 1st, 2018 were retrospectively analyzed. The anatomical types of TAPVC included supracardiac 42(40%, 42/105), cardiac 21(20%, 21/105), infracardiac 36(34.3%, 36/105), and mixed 6(5.7%, 6/105). The Cox proportional hazards analysis was used to analyze the risk factors related to postoperative pulmonary venous obstruction (PVO) and mortality. Kaplan- Meier analysis was used to analyze the overall survival rates. Results:Twenty-six patients (24.8%, 26/105) were diagnosed with preoperative PVO. The 30-day, 1 year, and 5 years survival rate was 92.4%, 86.7%, and 86.7% respectively. Postoperative PVO occurred in 17 patients (16.2%, 17/105). Preoperative acidosis, low surgical weight, prolonged duration of cardiopulmonary bypass time, increasing postoperative central venous pressure (CVP), and reoperation were risk factors associated with mortality. Preoperative acidosis ( P<0.001), prolonged duration of cardiopulmonary bypass time ( P<0.001), and increasing postoperative CVP ( P=0.005) were independent risk factors for mortality. Mixed TAPVC, preoperative acidosis, low surgical age, prolonged cardiopulmonary bypass time, postoperative pulmonary arterial hypertension were risk factors associated with postoperative PVO. Prolonged cardiopulmonary bypass time ( P=0.029), postoperative pulmonary arterial hypertension ( P<0.001), and mixed TAPVC ( P=0.017) were independent risk factors associated with postoperative PVO. Conclusion:The surgical outcomes of neonatal TAPVC in our center were acceptable, with low mortality rate and incidence of PVO. However, neonates with preoperative acidosis, prolonged duration of cardiopulmonary bypass time, and increased postoperative CVP had a poor prognosis. Patients with mixed TAPVC were at increased risk for postoperative PVO.

BACKGROUND: Thyroid dysfunction is associated with cardiovascular diseases. However, the role of thyroid function in lipid metabolism remains partly unknown. The present study aimed to investigate the causal association between thyroid function and serum lipid metabolism via a genetic analysis termed Mendelian randomization (MR). METHODS: The MR approach uses a genetic variant as the instrumental variable in epidemiological studies to mimic a randomized controlled trial. A two-sample MR was performed to assess the causal association, using summary statistics from the Atrial Fibrillation Genetics Consortium (n = 537,409) and the Global Lipids Genetics Consortium (n = 188,577). The clinical measures of thyroid function include thyrotropin (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) levels, FT3:FT4 ratio and concentration of thyroid peroxidase antibodies (TPOAb). The serum lipid metabolism traits include total cholesterol (TC) and triglycerides, high-density lipoprotein, and low-density lipoprotein (LDL) levels. The MR estimate and MR inverse variance-weighted method were used to assess the association between thyroid function and serum lipid metabolism. RESULTS: The results demonstrated that increased TSH levels were significantly associated with higher TC (β = 0.052, P = 0.002) and LDL (β = 0.041, P = 0.018) levels. In addition, the FT3:FT4 ratio was significantly associated with TC (β = 0.240, P = 0.033) and LDL (β = 0.025, P = 0.027) levels. However, no significant differences were observed between genetically predicted FT4 and TPOAb and serum lipids. CONCLUSION Taken together, the results of the present study suggest an association between thyroid function and serum lipid metabolism, highlighting the importance of the pituitary-thyroid-cardiac axis in dyslipidemia susceptibility.

Objective    To quest the risk factors of poor prognoses in children with tetralogy of Fallot (TOF) during perioperative period and evaluate its clinical application values. Methods    A retrospective analysis of the clinical data of 119 children who underwent one-stage correction of TOF in Guangdong Provincial People's Hospital from September 2016 to January 2019. The cohort includes 75 males and 44 females, with ages ranging from 3.2-137.1 (13.2±1.4) months and weights ranging from 4.6-21.0 (8.3±0.2) kg. Perioperative poor prognosis was defined as duration of mechanically assisted ventilation >48 h or secondary intubation, vasoactive-inotropic score (VIS) within 48 h >40, postoperative length of stay >14 d, and the occurrence of the major adverse events. Major adverse events were defined as early death, malignant arrhythmia, low cardiac output syndrome, non-fatal cardiac arrest, postoperative reintervention, diaphragm paralysis, and other clinical complications. Univariate and multivariate logistic analyses were used to analyze the correlation between risk factors and poor prognoses. Results    There was 1 perioperative death, and 9 with major adverse events. Variables selected by Least Absolute Shrinkage and Selection Operator (LASSO) included 2 preoperative variables (McGoon index, aortic root diameter index) and 4 intra-operative variables [left-right direction of bicuspid pulmonary valve, total length of right ventricular outflow tract (RVOT) incision index, pulmonary valve with commissurotomy, and minimum temperature in cardiopulmonary bypass (CPB)]. Univariate and multivariate logistic analyses were used to the above factors, respectively. The variables with statistical significance (P≤0.05) were McGoon index, aortic root diameter index, left-right direction of bicuspid pulmonary valve, and minimum temperature in CPB. A nomogram was established based on the above factors, and the results showed that the left-right direction of bicuspid pulmonary valve was more risky than the tricuspid pulmonary valve and the anterior-posterior direction of bicuspid pulmonary valve. The lower the McGoon index, the higher aortic root diameter, and the lower temperature in CPB, the higher risk of poor prognostic events in children with TOF. Conclusion    The left-right direction of the pulmonary bicuspid valve has a higher risk of poor prognosis than the tricuspid pulmonary valve and the anterior-posterior direction of bicuspid pulmonary valve. With the smaller McGoon index and the larger aortic root diameter, the risk of poor prognoses in children with TOF is higher. The temperature in CPB being lower than medium-low temperature obviously relates to the high incidence of poor prognostic events, which can be used as an auxiliary reference standard for decision-making in pediatric TOF surgery in the future.

Objective: To analyze the current status of clinical treatment and factors influencing postoperative mortality in infants with critical congenital heart disease (CCHD) in China, optimize the perioperative management of CCHD, and provide a new scientific basis for clinical decision-making for the optimal management of these patients. Methods: This is a retrospective single-center study. Infants diagnosed with CCHD in Guangdong Provincial People's Hospital from January 2017 to December 2019 (aged 0-1 years at admission) were enrolled. General clinical information, inpatient treatment information, prognosis and complications were collected and analyzed. Multivariate logistic regression analysis was used to explore the independent risk factors of postoperative death in infants with CCHD. Results: A total of 826 infants with CCHD were included, including 556 males (67.3%) and the age at first admission was 51.0 (5.0,178.3) days. 264 (32.0%) cases were tetralogy of Fallot and 137 (16.6%) cases were total anomalous pulmonary venous return. 195 cases (23.6%) were diagnosed prenatally. 196 cases (23.7%) were treated with prostaglandin. The preoperative invasive ventilation time was 0 (0, 0) hour, and the postoperative invasive ventilation time was 95.0 (26.0, 151.8) hours. A total of 668 cases (80.9%) underwent surgical treatment. The age was 100.5 (20.0, 218.0) days during operation and the operation time was 190.0 (155.0, 240.0) hours. Sixty-two cases (7.5%) received medical treatment, and 96 cases (11.6%) gave up treatment. A total of 675 cases (81.7%) were discharged with improvement, 96 cases (11.6%) were discharged after giving up treatment, 55 cases (6.7%) died and 109 cases (13.2%) were readmitted within one year. Complications occurred in 565 (68.6%) cases, including pneumonia in 334 cases (40.4%) and cardiac arrhythmias in 182 cases (22.0%). Multifactorial analysis showed that delayed chest closure (OR=49.775, 95%CI 3.291-752.922, P=0.005), prolonged post-operative invasive ventilator ventilation (OR=1.003, 95%CI 1.000-1.005, P=0.038) and cardiac hypoplasia syndrome (OR=272.658, 95%CI 37.861-1 963.589, P<0.001) were the independent risk factors for mortality in CCHD infants post-operation. Conclusions: Tetralogy of Fallot and total anomalous pulmonary venous return account for the majority of infants with CCHD. The proportion of infants diagnosed prenatally was less than 1/4. The majority CCHD infants received surgical treatment. The main complications are pneumonia and arrhythmia. Delayed chest closure, prolonged postoperative invasive ventilator ventilation and low cardiac output syndrome are the independent risk factors for postoperative death in infants with CCHD.

Aim To investigate the effects of YL- IPA08 on the endogenous metabolites of PTSD model rats by metabolomics methods, and to explore the metabolic pathways and possible mechanisms of YL-IPA08 against PTSD. Methods The rats were randomly divided into control group, PTSD model group, and administration group of PTSD rats induced by forced swimming test, and the treatment group was given YL- IPA08 (2 mg • kg"1) by intragastric gavage for 15 consecutive days. High-performance liquid chromatog- raphy-mass spectrometry (HPLC-MS/MS) technology was used to detect the endogenous differential metabolites and the associated metabolic pathways in rat plasma samples. Targeted quantitative technology was simultaneously applied to detect the concentrations of 18 bile acids in rat plasma. Results Compared with control group, 40 kinds of endogenous metabolites including glutamic acid, proline, valine, arginine, leucine , cholic acid, and creatine showed significant difference, and the concentrations of 11 bile acids significantly increased in plasma of model group as well. Compared with model group, after YL-IPA08 intervention , the above-mentioned potential metabolites ap-peared to return to normal levels. Conclusions Metabolomics analysis reveals that YL-IPA08 has intervention effect on PTSD model rats. The mechanism may be related to the regulation of amino acid metabolism and bile acid metabolism.
