Objective:To explore the environmental risk factors of different categories of congenital heart defects ( CHD) and provide evidence for further risk factors and prevention research of CHD pheno-types. Methods:Data of Guangdong CHD Register Study from 2004 to 2012 were used. In the study, 3 038 CHD cases and 3 038 paired controls from 34 hospitals distributed in 17 cities were registered and related information were collected using uniform, and structured questionnaires. All the CHD phenotypes were coded according to the International Classification of Diseases 10th Revision (ICD-10) and classified into 6 categories according to their pathological features. Univariate analyses were adopted to filter poten-tial risk factors for each category of CHD. Then multivariate conditional Logistic regression was used to calculate the odds ratios of the risk factors for each category of CHD. Results:The risk factors for left-to-right shunt CHD included low ( OR=2 . 63 , 95%CI:2 . 04 -3 . 39 ) or over birth weight ( OR =2 . 21 , 95%CI:1 . 47-3 . 32 ) , premature delivery ( OR=1 . 95 , 95%CI:1 . 53-2 . 49 ) , polyembryony ( OR=1. 99, 95%CI: 1. 22 -3. 26), maternal low education, mother as factory worker (OR =1. 62, 95%CI:1 . 32-1 . 98 ) , parity≥2 ( OR =1 . 38 , 95%CI: 1 . 13 -1 . 69 ) , maternal abnormal reproduction history ( OR=2 . 29 , 95%CI:1 . 75-3 . 01 ) , fever ( OR=2 . 38 , 95%CI:1 . 26-4 . 48 ) , virus infection ( OR=1 . 80 , 95%CI:1 . 29 -2 . 51 ) , medicine usage ( OR=1 . 73 , 95%CI:1 . 11 -2 . 69 ) , passive smoking ( OR=1 . 69 , 95%CI:1 . 26-2 . 29 ) , chemical agent contact ( OR=8 . 71 , 95%CI:2 . 33 -32 . 58 ) , living in newly decorated houses ( OR=2 . 56 , 95%CI:1 . 60-4 . 09 ) or room close to the main road ( OR=1 . 40 , 95%CI:1 . 14-1 . 72 ) in the first 3 months of pregnancy and father as factory worker ( OR=1 . 46 , 95%CI:1 . 23-1 . 73 ) . The risk factors for pulmonary outflow tract obstruction CHD in-cluded low ( OR =5 . 98 , 95% CI: 2 . 88 -12 . 44 ) or over birth weight ( OR = 6 . 56 , 95% CI:1. 19-36. 26), maternal low education, parity≥2 (OR=2. 08, 95%CI:1. 03-4. 22), virus infection in the first 3 months of pregnancy ( OR =4 . 30 , 95%CI: 1 . 27 -13 . 45 ) . The risk factors for left ventricular outflow tract obstruction CHD included father as factory worker ( OR=6 . 01 , 95%CI:1 . 05-34. 59).

The risk factors for other CHD included over birth weight (OR=4. 87, 95%CI:1. 19-19. 94), maternal abnormal reproduction history (OR=2. 96, 95%CI:1. 14 - 7. 68 ), virus infection ( OR = 4. 92, 95% CI: 1. 56 - 15. 47 ), medicine usage (OR=4. 90, 95%CI:1. 22-19. 77) or passive smoking (OR=10. 31, 95%CI:1. 25-85. 05) in the first 3 months of pregnancy. Conclusion:The environmental risk factors were discrepant among different categories of CHD. Further risk factors study of CHD phenotypes should be performed specially. To prevent CHD, attention should be paid to the risk factors which are related to multi or complex categories of CHD.

OBJECTIVETo investigate the risk factors for post-stroke pneumonia and assess the value of A(2)DS(2) score in predicting post-stroke pneumonia in elderly stroke patients.

METHODSThe clinical data were retrospectively collected from elderly stroke patients from January, 2007 to December, 2012. A(2)DS(2) score was then assigned using the clinical information from the medical record. The ability of the score to discriminate between patients with post-stroke pneumonia and those without was quantified using ROC analysis. The calibration of the score was analyzed using Hosmer-Lemeshow goodness-of-fit test.

RESULTSA total of 131 elderly male stroke patients were enrolled in this study, among whom the incidence of post-stroke pneumonia was 29.01%. The independent risk factors for post-stroke pneumonia identified included moderate (P=0.0081, OR: 5.6089; 95%CI: 1.5663-20.0854) and severe (P=0.0048, OR: 44.4827; 95%CI: 3.1847-621.3126) neurological impairment, dysphagia (P=0.0005, OR: 7.5265; 95%CI: 2.4282-23.3292), and atrial fibrillation (P=0.0226, OR: 4.1778; 95%CI: 1.2221-14.2825). The incidence of post-stroke pneumonia ranged from 2.2% in patients with a A(2)DS(2) score less than 3 to 75% in those with a score higher than 8. The C-statistic of A(2)DS(2) score for predicting post-stroke pneumonia was 0.86 (95%CI: 0.784-0.911) by the ROC analysis. The A(2)DS(2) score was well calibrated to predict post-stroke pneumonia in elderly patients by Hosmer-Lemeshow test (7.083, P=0.528).

CONCLUSIONThe A(2)DS(2) score can be useful for predicting post-stroke pneumonia and for routine monitoring of high-risk elderly stroke patients in the clinical setting.

Objective This retrospective cohort study aims to evaluate and compare the prognosis of surgical repair for total anomalous pulmonary venous connection(TAPVC) with different drainage type.Methods From January 2006 to Decem-ber 2013, 328 consecutive patients were enrolled in this study .The distribution of the defects was 109 cases with cardiac, 161 with supracardiac, 32 with infracardiac, and 26 with mixed type of the drainage into the systemic circulation .The clinical re-cords of all the patients were reviewed.Studied variables were extracted from the clinical records.Followed-up was conducted at an interval of 1 month, 3 months, 6 months and then once a year post-operation.Prevalence of peri-operative conditions were compared among four different types.Studied endpoints was defined by postoperative total death or pulmonary venous obstruc-tion(PVO), which was evaluated with Kaplan-Meier curve and multivariable Cox proportional hazard model, adjusted by differ-ent surgical strategy, emergency operation, preoperative-PVO, neonates, weight, combing with other complex cardiac defects,NYHA cardiac function, severe pulmonary hypertension and severe tricuspid regurgitation.Results There were significant discrepancyof preoperative conditions among four types of TAPVC.Patients with infracardiac TAPVC presented the most criticalsymptoms and clinical indexes, which included having largest proportion of neonates, preoperative PVO, severe NYHA grading,pulmonary hypertension and tricuspid regurgitation, having lowest body weight at operation and youngest age.The cardiopulmonarybypass time, aortic crossclamp time and mechanical ventilation time were significantly longer in infracadiac and mixedTAPVC comparing to the other two types.For early mortality(death in hospital), infracadiac(9.4%) and mixed(11.5%)TAPVC demonstrated higher rates of death than cardiac(4.6%) and supracardiac(7.5%)TAPVC, although had no statisticalsignificance.For intermediate-term results, mortality in infracadiac(21.9%) and mixed(30.8%) TAPVC were significantlyhigher than cardiac ( 8.3%) and supracardiac (11.8%) TAPVC.Reoperation was more frequently required in mixed(19.2%), then infracadiac(15.6%)TAPVC.Mixed and infracadiac types are independent risk factors for TAPVC prognosis,after adjusting by the confounding factors.Conclusion Mixed and infracadiac types are independent risk factors for postoperativedeath and PVO among TAPVC patients.This study provided evidence for clinical assessment and management strategy fordifferent types of TAPVC.

Objective: To have a profound understanding of anti-N-methyl-D-aspartic receptor (anti-NMDAR) encephalitis, through the clinical analysis of 5 cases of anti-NMDAR encephalitis, and literature review. Methods: This is a retrospective analysis. Five cases of anti-NMDA receptor encephalitis treated from May 2010 to June 2015, in the Department of Neurology, Beijing Friendship Hospital affiliated to Capital Medical University, were included in this study. The clinical data, including clinical manifestation, past history, radiological features, serum and cerebral spinal fluid examinations, treatment and prognosis, were analyzed. Results: Among the 5 cases, 3 young female and 2 middle-to old-aged male. The clinical features of the onset was mental and behavior disorder, as well as seizure and extrapyramidal features, like facial and limbic involuntary movements or tremor. Coma and hypopnea was severe in 3 young female cases, needing assistance of mechanical ventilator, while the manifestation of 2 male patients was much mild, need not assisted respiration. 1 case had teratoma of ovary, 1 case had Vogt-Koyanagi-Harada syndrome. The anti-NMDA receptor antibody was positive in cerebraospinal fluid of all 5 cases, but in serum of 3 cases, serum and CSF Epstein-Barr virus (EBV) IgM antibody was positive in 1 case, while herpes simplex I virus (HSV-1) IgM antibody positive in another case, and anti-myelin oligodendrocyte glycoprotein (MOG) antibody was seen in serum and CSF in 1 case. The time interval from the onset to treatment was 10-37 d (18.8±9.8 d). IVIG was used in all of the 5 cases, glucocoticoid in 4 cases, and plasma exchange in 3 cases. One case with Vogt-Koyanagi-Harada syndrome, having a long time before diagnosis and treatment, died, while the other 4 cases had good prognosis, and had no relapse. Conclusions Mental and behavior disturbance is common at onset of anti-NMDAR encephalitis. The radiological and lab examination may be normal. It may be accompanied with HSV-1 or EBV infection, anti-MOG antibody may be positive in this disease. Active treatment is important.

Objective To evaluate the accuracy of 3D models of patients with complex congenital heart disease(CHD) printed by domestic 3D priuters based on cardiac CT data.Methods From April 2018 to June 2018,our hospital used domestic 3D printers to print the hearts of 50 patients with complex CHD.The median age of the patients was 24 months(1 month to 61 years),and the diseases included pulmonary atresia,right ventricular double outlet and transposition of aorta.3 measurement sites(150 in total) were selected for each patient.Pearson correlation coefficient calculation,paired t test and Bland-Altman analysis were performed.Results Pearson correlation coefficient is 0.997.The difference of the measured value of CT-model was tested for normality.P was 0.2 of the D test.The Q-Q graph showed that the data point and the theoretical line were highly overlapped.The mean difference was (-0.07 ± 0.67) mm,P =0.196.In Bland-Altman analysis,the consistency boundary value interval of the difference was(-1.29 mm,1.16 mm) between which there were 143/150(95.33％) points.Conclusion 3D models of patients with complex CHD printed by domestic 3D printers based on cardiac CT data have good accuracy.

Objective:To analyze the accuracy of lung ultrasound and chest X-ray in the diagnosis of neonatal pulmonary disease.Methods:We prospectively collected newborns that needed chest X-ray examination to diagnose pulmonary disease from twelve neonatal intensive care units across the country between June 2019 and April 2020.Each newborn was examined by lung ultrasound within two hours after chest X-ray examination.All chest X-ray and lung ultrasound images were independently read by a radiologist and a sonographer.When there was a disagreement, a panel of two experienced physicians made a final diagnosis based on the clinical history, chest X-ray and lung ultrasound images.Results:A total of 1 100 newborns were enrolled in our study.The diagnostic agreement between chest X-ray and lung ultrasound(Cohen′s kappa coefficient=0.347) was fair.Lung ultrasound(area under the curve=0.778; 95% CI 0.753-0.803) performed significantly better than chest X-ray(area under the curve=0.513; 95% CI 0.483-0.543) in the diagnosis of transient tachypnea of the newborn( P<0.001). The accuracy of lung ultrasound in diagnosing neonatal respiratory distress syndrome, meconium aspiration syndrome, pneumonia and neonatal pulmonary atelectasis was similar to that of chest X-ray. Conclusion:Lung ultrasound, as a low-cost, simple and radiation-free auxiliary examination method, has a diagnostic accuracy close to or even better than that of chest X-ray, which may replace chest X-ray in the diagnosis of some neonatal lung diseases.It should be noted that both chest X-ray and lung ultrasound can only be used as auxiliary means for the diagnosis of lung diseases, and it is necessary to combine imaging with the clinical history and presentation.

Objective To retrospectively analyse the outcomes following primary Sutureless technique used in our hospi-tal for neonates with total anomalous pulmonary venous connection(TAPVC)and sum up surgical operative experiences. Meth-ods Date were collected retrospectively in 42 neonates who underwent primary Sutureless technique for TAPVC between Janu-ary 2008 and December 2015. Cardiopulmonary bypass time,aortic clamped time,velocity of pulmonary veins and other relat-ed data were recorded during and after operation. Results There were 31 males and 11 females with median age of 8. 0 days old,of whom 25 were supracardiac TAPVC(59. 5％)and 17 were infracardiac TAPVC(40. 5％). After operation, 1 neonate died and none suffered from pulmonary vein obstruction(PVO). In follow-up period,there was 1 neonates suffered from PVO. Six neonates came back to hospital again because of septicemia,poor wound healing,bronchopneumonia and incomplete intesti-nal obstruction. Conclusion Sutureless technique is a wise surgical strategy for neonates with TAPVC for better outcomes and decreasing postoperative mortality rate and recurrence rate of PVO.

Objective To evaluate the application of three-dimensional printing technique in surgical treatments on complex congenital heart diseases. Methods Two patients were enrolled with complex congenital heart diseases. The computerized tomography data were used to build the 3D architecture of cardiac anomalies. The White-Jet-Process technique was used to print the models with 1∶1 ratio in size. The models were used to make the treatment strategy making, young surgeon training and operation simulation. Results The full color and hollowed-out cardiac models with 1∶1 ration in size were printed successfully. They were transected at the middle point of vertical axis, which was conveniently to explore the intracardiac anomalies. However, for patient 1, the model lost the atrial septal defect. Taking the two models as references, operation group held preoperative consultation, operation simulation, and finally, the operation plans were determined for the two patients. Both the two operation were carried out smoothly. Conclusion Although the limitations of 3D printing still exist in the application for congenital heart diseases, making the preoperative plan and operation simulation via 3D cardiac model could enhance the understanding of following operation and procedure details, which could improve the tacit cooperation among operation group members. Furthermore, operation results also could be improved potentially. Therefore, the cardiac 3D printing should be popularized in clinic in the future.

Objective    To analyze the sutureless technique use in the surgical repair for total anomalous pulmonary venous connection in neonates. Methods    Between September 2002 and December 2015, 71 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. There were 57 males and 14 females at median age of 8 (1, 29) d. And the median body weight was 3.3 (2.1, 4.7) kg. There were 45 patients (63.4%) with supracardiac, 26 patients (36.6%) with infracardiac. Patients were divided into two groups: a conventional technique group (29 patients) and a sutureless technique group (42 patients). To control for potential differences in the characteristics of patients between the sutureless technique group and the conventional technique group, the method of propensity-score matching was used. Results    Basic characteristics of patients after propensity-score were not different.There were 11 operative deaths (15.5%), 7 late deaths (96.%), total 18 deaths (25.4%). The mortality was 58.6% (17/29) in the conventional technique group, 2.4% (1/42) in the sutureless technique group (P=0.000). Kaplan-Meier survival curve showed a difference in   mortality between the two groups (P=0.005). The patients were followed up for 25.5 (1.0-13.0) months.Postoperative anastomotic or pulmonary vein stenosis occurred in 12 patients, 8 of them died at a higher mortality than that of the patients with smooth anastomosis [66.7% (8/12) vs. 16.9% (10/59), P=0.001]. Conclusion    The patients who have postoperative anastomotic or pulmonary vein stenosis have higher mortality. Compared with conventional technique, sutureless technique can dramatically decrease the incidence of postoperative anastomotic or pulmonary vein stenosis and the mortality of surgical repair for total anomalous pulmonary venous connection in neonates.
