Objective To investigate the event-based prospective memory(EBPM)and time-based prospective memory(TBPM)in schizophrenia patients with concomitant metabolism syndrome,and to provide theory basis for early intervention and treatment.Methods According to inclusion standard,50 schizophrenia patients with concomitant metabolism syndrome and 50 schizophrenia patients without metabolism syndrome matched in age,gender and education were assessed with a neuropsychological battery of tests including EB-PM and TBPM tasks.Results In the EBPM task,there was significant difference between schizophrenia pa-tients with and without metabolism syndrome (3.46±0.91 vs 3.86±0.81, t=-2.326, P=0.022).A statistically significant difference in TBPM was observed between schizophrenia patients with and without metabolism syn-drome (3.02±1.12 vs 3.78±0.89, t=-3.770, P=0.000).Conclusion The schizophrenia patients with me-tabolism syndrome have severer prospective memory impairment than those without metabolism syndrome.

ObjectiveTo investigate the prevalence and risk factors of dental caries and its related influencing factors in 12-year-old children in Yangpu District， Shanghai， and to provide relevant data support for the formulation of oral health policies and measures for children. MethodsIn 2021， 839 12-year-old children were randomly selected from five ordinary junior high schools in Yangpu District. The investigation included an oral health examination and a questionnaire survey on factors related to dental caries. Logistic regression analysis was used to analyze the influencing factors of dental caries. ResultsAmong the 839 participants， data from 830 were included. Among them， 426 were male （51.3%） and 404 were female （48.7%）. Of the 830 children， 203 had dental caries， resulting in a caries prevalence of 24.46%， a caries supplemental filling ratio of 32.6%， and a DMFT of 0.63. Multivariate logistic regression analysis revealed that a mother’s education level of college or above （OR=0.849，95% CI： 0.732‒0.984）， brushing teeth twice a day （OR=0.827，95%CI： 0.703‒0.973）， and the caregiver brushing teeth twice a day （OR=0.843， 95%CI： 0.726‒0.983） were effective factors in reducing the caries rate. Factors associated with childhood dental caries included consuming sweets ≥1 time per day （OR=1.397，95%CI： 1.197‒1.342） and female gender （OR=1.482，95%CI： 1.347‒1.671）. ConclusionThe prevalence of dental caries among 12-year-old children in Yangpu District is 24.46%. Gender， maternal education， the frequency of children's toothbrushing， the frequency of sweet consumption， and the caregiver’s toothbrushing frequency are the main factors affecting the prevalence of dental caries in children.

Objective: To review current-era palliation outcomes of patients with heterotaxy and functional single ventricle in a single institution. Methods: The clinical data of 70 consecutive patients with heterotaxy undergoing multistage single ventricle palliation in Guangzhou Women and Children′s Medical Center from January 2008 to December 2017 were retrospectively reviewed, and the prognosis factors for mortality were analyzed. There were 53 male and 17 female patients.The median age was 13.3 months (range: 6 days to 150 months). Single ventricle multistage palliation included 1^st stage palliation surgery, 2^nd bidirectional Glenn shunt, and 3^rd stage modified Fontan.The Kaplan-Meier method was used to estimate the probability of survival. Multivariate analysis was performed by Cox regression model. Results: Sixty-two patients had right atrial isomerism while eight had left atrial isomerism. Eighteen patients (25.7%) required the first stage palliation. Fifty-five patients received the Glenn shunt, and the Fontan procedure was completed in 27 patients. Overall, mortality occurred in 17 patients (24.3%) including 9 after the first stage palliation, 6 after the Glenn shunt, and 2 following the Fontan procedure. Survival estimates for the entire cohort following surgery were 81% (95%CI: 72% to 90%), 74%(95%CI: 64% to 85%), and 74% (95%CI: 64% to 85%) at 1 year, 5 years and 10 years, respectively. Survival estimates following the first stage palliation were 56% (95%CI: 33% to 79%) and 49% (95%CI: 26% to 73%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (TAPVC) (HR=6.16, 95%CI: 1.65 to 22.95, P=0.007), atrioventricular valve regurgitation more than moderate (HR=3.81, 95%CI: 1.32 to 10.94, P=0.013) and required the first palliation surgery (HR=4.58, 95%CI: 1.34 to 15.72, P=0.016) were prognosis factors for overall mortality. Conclusions The management of heterotaxy patients with functional single ventricle remains challenging, and the outcomes are continously improving in china. TAPVC, atrioventricular valve regurgitation more than moderate and required the first palliation surgery still are prognosis factors for overall mortality in heterotaxy syndrome.

Objective Analyze the surgical and follow-up outcomes of congenital coronary artery fistula(CAF) in children and to discuss the treatment methods.Methods The clinical data were analyzed retrospectively in 22 patients who were diagnosed as congenital CAF and received surgical treatment between July 2008 and January 2017 in Guangzhou Women and Children's Medical Center.There were 14 boys and 8 girls.The median age was 17 months ranging from 14 days to 12 years old.The median weight was 8.8 kilograms ranging from 3.0 to 31.0 kilograms.Results Two patients had shortness of breath.Three had growth retardation with recurrent respiratory infection or tachypnea.The remaining 17 patients were asymptomatic.Twenty had heart murmurs.Fistulas originated from right coronary artery accounted for 11 patients,with 10 from left coronary artery,1 from both right and left coronary arteries.Fistulas drained into coronary sinus in 1 patient,right atrium in 6 patients,right ventricular in 13 patients and left ventricular in 2 patients.Single fistula occurred in 20 patients and multiple fistulas in 2 patients.The coronary arteries were obviously dilated in all patients with diameter from 4.0 to 12.0 millimeters.There were 8 cases with aneurysmal dilation of coronary arteries.Two patients underwent fistula ligation without cardiopulmonary bypass(CPB).The remaining 20 cases received fistula correction with beating heart CPB.Direct suture was used in 3 patients for closure of fistula inlet and 11 children for outlet.Both inlet and outlet were closed in 6 patients,and in 2 of them autologous pericardial patch was used for outlet.Other associated intra-cardiac anomalies in 7 children were corrected during the operation.The aneurysmal coronary arteries remained original shape without any intervention during the operation.The mean hospital delay was(12.3±3.2) days.Two patients appeared decreased heart function within 3 days after the operation,and recovered in return visit one month later.Another 2 patients showed a residual shunt with size of 1 to 2 millimeters through the fistula without further intervention after the surgical closure.During the perioperative period and the follow-up period(3 months to 8 years),all 22 patients were asymptomatically alive without regular anticoagulation management.Transthoracic echocardiography showed normal cardiac function.Compared with preoperative status,the diameter of dilated coronary arteries was reduced over 6 months follow up after the operation.There were no formation of thrombus in the coronary arteries.Electrocardiography showed no ST-T changes or arrhythmia or myocardial ischemia.Conclusion Clinical symptoms can be appeared in children with congenital CAF due to large shunt.Surgical correction is an effective method for the management of single CAF or CAF with coexisted intra-cardiac anomalies.The outcome was well.

Objective:To build a medical service experience system based on role play of hospital staff, and explore its contribution to upgrading medical service, elevating medical service quality, and improving patients′ satisfaction.Methods:An indicator system for medical service experience was developed via literature review. 20 newly recruited hospital employees in 2019 were sampled randomly to form a service experience team, who were arranged to experience the full medical service process of outpatients and inpatients based on role play. The questionnaire for service quality based on patient perception and expectation was used to survey the expectation and perception values of those role players on their medical service experiences, and summarize the defects found on such six dimensions as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness. After due corrections of these defects, further experiences and patient satisfaction survey were made to assess the effects of such actions taken. Paired t test was used respectively in statistical analysis of service experience value and actual perception value, as well as the perception values before and after the actions taken, and χ2 test was used for a statistical analysis of patient satisfaction. Results:Role players experienced respectively at the emergency, outpatient and inpatient departments of the hospital for a week in August 2019. Statistics of their experiences indicated≥0.50 points difference between the mean expectation and perception values on doctor-patient communication, patient help responsiveness, outpatient process, examination report delivery duration, service attitude, patient trust on medical workers, medical environment and patient privacy protection.Following a 3-month reform, role players found improvements in such aspects as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness; patient satisfaction improved sizably in December 2019 over January of the same year( P<0.05). Conclusions:The construction and application of the medical service experience system based on role play of hospital staff prove highly useful in upgrading medical service actions, improving medical service quality, and improving patient satisfaction.

Objective To analyze the treatment and follow-up of congenital coronary artery fistula (CAF) with giant coronary artery aneurysm (GCAA) in children.Methods The clinical data were analyzed retrospectively in 13 patients who were diagnosed as congenital CAF with GCAA between July 2009 and December 2016 in Guangzhou Women and Children's Medical Center.There were 8 boys and 5 girls.The median age was 18 months,ranging from 40 days to 12 years old.The body weight ranged from 3.8 kg to 29.0 kg with a median of 8.8 kg.Fistulas originated from right coronary artery accounted in 8 patients,with 5 from left coronary artery.Fistulas drained into right atrium in 3 patients,right ventricular in 8 patients and left ventricular in 2 patients.Single fistula occurred in 12 patients and multiple fistulas in 1 patient.The diameter of coronary artery aneurysm ranged from 8 mm to 16 mm with a median of 9.2 mm.Results One patient had tachypnea and growth retardation without heart murmur.The other 12 patients were asymptomatic with heart murmurs occasionally found in routine physical examination.One patient underwent fistula ligation without cardiopulmonary bypass (CPB).The remaining 12 cases received fistula correction with beating heart CPB.Direct suture was used in 10 patients and autologous pericardial patch in other 2 patients.Two patients were associated with atrial septal defect (ASD) and underwent repair of ASD concurrently.The coronary artery aneurysm remained original shape without any intervention during the operation.The mean hospital delay was (11.0 ± 2.5) days.Two patients had decreased ejection fraction as low as 38％ within 3 days after the operation,but went up to over 50％ in follow-up 1 month later.Transient T wave change occurred in 7 patients,and another 2 patients showed a residual shunt with size of 1 to 2 millimeters through the fistula without further intervention after the surgical closure.All 13 patients had antiplatelet therapy with 12 taking Aspirin and one taking Dipyridamole.The dosage was 3-5 mg/(kg · d) with duration ranging from 3 days to 13 months with a median of 1 month.During the perioperative period and the follow-up period (3 months to 8 years),all patients were asymptomatically alive.Transthoracic echocardiography showed normal cardiac function.Compared with preoperative status,the diameter of dilated coronary arteries was not changed after the operation.There was no formation of thrombus in the coronary arteries.Electrocardiography showed no ST-T changes or arrhythmia or myocardial ischemia.Conclusions GCAA can be combined with congenital CAF in children,so it needs early operation.The evidence-based intervention of coronary artery aneurysm and usage of anticoagulant and antiplatelet therapy in pediatric patients was still lacking,which needs long-term follow-up.
