Objective:To analyze the vaccination recommendations and follow-up for children with special health status.Methods:In this retrospective cohort study, 509 children who attended the Consultation Clinic of Vaccination for Special Health Children in Beijing Children′s Hospital from August 2020 to February 2023 were selected, the children were given vaccination planning advice after the assessment. The clinical data were collected, including the general situation, special health conditions, vaccination recommendations and implementation status, occurrence and outcomes of suspected adverse events following immunization (AEFI) after vaccination. The vaccination situation and safety in these children were evaluated.Results:Among the 509 children, the most common special health conditions were cardiovascular system diseases (103 cases), followed by neurological diseases (88 cases) and neonatal problems (82 cases). After comprehensive evaluation and multidisciplinary collaboration, 399 children (78.4%) were recommended to receive vaccination/catch-up vaccination according to the immunization program, 63 children (12.4%) were recommended to receive some vaccines but temporarily suspend others, and 47 children (9.2%) were recommended to temporarily suspend vaccination. A total of 449 children (88.2%) were actually vaccinated, AEFI occurred in 49 children and 45 cases were considered as general reactions.Conclusions:The majority of children with special health status can be vaccinated, and the overall compliance and safety are high. The individualized immunization evaluation model of multidisciplinary collaboration is conducive to the completion of the immunization program of children with special health status.

Objective:To explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge.Methods:This study was a retrospective cohort study that included 268 children with bacterial meningitis who were discharged from the infectious medicine ward of Beijing Children′s Hospital from September 2018 to September 2023. The children were managed with a multidisciplinary collaborative comprehensive healthcare management model after discharge. Outpatient data at 1 month and 6, 12 and 24 months after discharge were collected, including (height, weight, body mass index, nutritional feeding status, hearing and vision screening results, Gesell developmental assessment results and intervention guidance services. The follow-up interval or frequency was dynamically adjusted or increased according to the child′s situation. The paired sample t-test and chi square test were applied to compare the differences in Gesell developmental quotient (DQ) and developmental delay rate between the first and last assessments to preliminarily explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge. Results:All the 268 children completed their first assessment one month after discharge, and 37 children were found to have abnormal physical growth, mainly obesity (28 children), and another 9 children were malnutrition. Nutritional intervention and feeding guidance services were provided to all the 37 children, and as of the last follow-up, 20 children′s physical growth evaluations had turned normal. A total of 188 children completed at least 2 developmental assessments, with an interval of (14.2±9.4) months between the first and last assessments (range: 3.1-49.5 months). The DQ values of in the energy region of adaptability, gross motor skills, fine motor skills, language, and personal social skills at the last assessment were significantly higher than those at the first assessment [(91.93±13.28) vs (80.73±15.96) points, (91.69±12.96) vs (78.31±16.58) points, (89.32±16.11) vs (80.68±15.63) points, (90.10±16.65) vs (82.04±18.43) points, (92.01±14.05) vs (77.82±17.42) points]; moreover, the rates of developmental delay in each energy region were significantly lower than those at the initial assessment (9.6% vs 35.1%, 9.6% vs 42.0%, 18.1% vs 33.0%, 13.3% vs 31.9%, 9.6% vs 42.0%) (all P<0.05). Among the 200 children who completed the hearing screening, 18 were found with hearing abnormalities, and 2 were diagnosed with hearing loss in the Otolaryngology Department. Among 217 children who completed vision screening, 23 had abnormalities, and 5 were diagnosed with ophthalmic abnormalities in Ophthalmology Department (2 with strabismus, 2 with refractive errors, and 1 with optic nerve injury). Two children were found to have autism-like behavior during monitoring, and were referred to a developmental behavior clinic to be diagnosed with autism spectrum disorder and were given early diagnosis and intervention guidance. Conclusion:The comprehensive healthcare management model for children with bacterial meningitis after discharge can integrate clinical and healthcare resources, which is beneficial for improving the prognosis and enhancing the quality of life for children with special health status.

Objective To compare the value of Child-Pugh score, Model for End-Stage Liver Disease (MELD) score, MELD combined with serum sodium concentration (MELD-Na) score, CLIF Consortium Acute Decompensation (CLIF-C AD) score, and Freiburg index of post-transjugular intrahepatic portosystemic shunt (TIPS) survival (FIPS) score in predicting the survival of patients undergoing TIPS. Methods A retrospective analysis was performed for the clinical data of 447 patients with liver cirrhosis who underwent TIPS in several hospitals in southwest China, among whom there were 306 patients in the survival group and 62 in the death group. The scores of the above five models were calculated, and a survival analysis was performed based on these models. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Pearson chi-square test was used for comparison of categorical data between groups; a multivariate Cox regression analysis was used for correction analysis of known influencing factors with statistical significance which were not included in the scoring models; the Kaplan-Meier method was used to evaluate the discriminatory ability of each model in identifying risks in the surgical population, and the log-rank test was used for analysis. The area under the receiver operating characteristic curve (AUC), C-index at different time points, and calibration curve were used to evaluate the predictive ability of each scoring model. Results Compared with the death group, the survival group had significantly lower age ( Z =2.884, P < 0.05), higher albumin ( t =3.577, P < 0.05), and Na + ( Z =-3.756, P < 0.05) and significantly lower proportion of patients with alcoholic cirrhosis ( χ 2 =22.674, P < 0.05), aspartate aminotransferase ( Z =2.141, P < 0.05), prothrombin time ( Z =2.486, P < 0.05), international normalized ratio ( Z =2.429, P < 0.05), total bilirubin ( Z =3.754, P < 0.05), severity of ascites ( χ 2 =14.186, P < 0.05), and scores of the five models (all P < 0.05). Survival analysis showed that all scoring models effectively stratified the prognostic risk of the patients undergoing TIPS. Comparison of the C-index of each scoring model at different time points showed that Child-Pugh score had the strongest ability in predicting postoperative survival, followed by MELD-Na score, MELD score, and CLIF-C AD score, and FIPS score had a relatively poor predictive ability; in addition, the prediction efficiency of each score gradually decreased over time. Child-Pugh score had the largest AUC of 0.832 in predicting 1-year survival rate after surgery, and MELD-Na score had the largest AUC of 0.726 in predicting 3-year survival rate after surgery, but FIPS score had a poor ability in predicting 1- and 3-year survival rates. Conclusion All five scoring models can predict the survival of patients with liver cirrhosis after TIPS and can provide effective stratification of prognostic risk for such patients. Child-Pugh score has a better ability in predicting short-term survival, while MELD-Na score has a better ability in predicting long-term survival, but FIPS score has a relatively poor predictive ability in predicting both short-term and long-term survival.

Objective:To explore the value of cardiac MRI (CMRI) in evaluating left atrial function in patients with postoperative tetralogy of Fallot (rTOF) and postoperative pulmonary stenosis (rPS).Methods:Totally 67 pediatric patients (49 with rTOF, 18 with rPS) with preserved left ventricular ejection fraction (EF) were recruited between January 2019 and October 2021 in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiao Tong University. Thirty-three healthy volunteers, matched in gender and age, were included as controls from July 2017 to August 2018. Left atrial EF, strain and strain rate of three phases (reservoir, conduit and pump), left atrial volume (maximum volume index, minimum volume index and pre-atrial contraction volume index) were measured with corresponding cardiac function analysis software. Then, the differences in these parameters were analyzed between the three groups by ANOVA or Kruskal-Wallis test with post hoc comparison and Bonferroni correction.Results:Compared with controls, patients with rTOF had lower reservoir function parameters (EF, strain and strain rate), conduit EF, conduit strain, and left atrial maximum volume index ( P<0.05), but higher pump EF ( P<0.05). In patients with rPS, only the reservoir strain rate decreased compared with controls ( P<0.05), and the remaining data showed no significant difference ( P>0.05). The reservoir and conduit EF and strain in patients with rPS were higher than those in patients with rTOF ( P<0.05). Conclusions:In patients with rTOF and rPS, left atrial function has changed despite the preservation of left ventricular EF, which may be an early marker of left ventricular diastolic dysfunction. In children with rTOF, left atrial reservoir and conduit functions decreased while the pump function increased. The reservoir and pump functions in rPS were better than those in rTOF. In addition, CMRI can detect left atrial dysfunction early before it enlarged.

Objective:To explore the neural mechanism of language dysfunction in patients with subacute stroke using functional near-infrared spectroscopy (fNIRS).Methods:Sixteen patients with non-fluent aphasia after subacute stroke (aphasia group), 16 patients with non-aphasia after stroke (non-aphasia group), and 16 healthy middle-aged and elderly subjects (control group) were enrolled into our study. The 6-min resting-state data of fNIRS were collected. Four language-related regions, Broca area, Wernicke area, dorso lateral prefrontal cortex (DLPFC), and supplementary motor area (SMA), were selected as regions of interest (ROIs), and the whole brain functional connection strength and functional connection strength in ROIs and between each two ROIs were analyzed by NirSpark software.Results:Compared with the control group (0.53±0.15) and non-aphasia group (0.47±0.12), the aphasia group had significantly decreased whole brain functional connection strength (0.29±0.14, P<0.05). Compared with the control group and non-aphasia group, the aphasia group had significantly decreased functional connection strength in the left Wernicke area, right Wernicke area, left Broca area, left SMA area, right SMA area and left DLPFC area ( P<0.05, FDR). Compared with the control group and non-aphasia group, the aphasia group had significantly decreased functional connection strength in the right Wernicke-left Wernicke area, right Wernicke-right Broca area, right Wernicke-left Broca area, right Wernicke-right DLPFC area, right Wernicke-left DLPFC area, right Wernicke-right SMA area, right Wernicke-left SMA area, left Wernicke-right Broca area, left Wernicke-left Broca area, left Wernicke-right DLPFC area, left Wernicke-left DLPFC, left Wernicke-right SMA area, left Wernicke-left SMA area, right Broca-left Broca area, right Broca-left DLPFC area, right Broca-right SMA area, right Broca-left SMA area, left Broca-right DLPFC area, left Broca-left DLPFC area, left Broca-right SMA area, left Broca-left SMA area, right DLPFC-left DLPFC area, right DLPFC-right SMA area, right DLPFC-left SMA area, left DLPFC-right SMA area, left DLPFC-left SMA area, and right SMA-left SMA area ( P<0.05, FDR). Conclusion:Abnormal functional connectivity strength of the whole brain and language-related key brain areas might be the neural mechanism of language dysfunction in patients with non-fluent aphasia after subacute stroke.

Health service is an important part of the integrated development of the Yangtze River Delta. Taking the cooperation practice between Shanghai Tenth People′s Hospital and Suzhou Yinshanhu Hospital as an example, this article introduced the multi-agent cooperation mode of the loose medical alliance including the government, urban hospitals and cross provincial grassroots medical institutions. Among them, the local government provided policy, fund guarantee and guidance, the urban hospital exported management ideas, medicine talents and technologies, and the primary hospital conducted dual training by inviting in and going out to achieve double growth. Through the high gap cooperation between tertiary hospital and primary hospital, Yinshanhu hospital had been comprehensively developed. The loose medical alliance with multi subject coordination and cross region could give full play to the advantages of the loose healthcare alliance mode, achieve multi-win, and have reference significance for promoting the regional integration of medical and health services in the Yangtze River Delta.

Objective:To analyze the causes and clinical features of chronic suppurative lung disease(CSLD) in children.Methods:We retrospectivly analyzed the primary disease, imaging changes, electronic fiber bronchoscope changes, blood gas analysis, lung function, treatment outcome and other clinical data of CSLD in children hospitalized in our hospital from September 2018 to February 2020.Results:A total of 14 children with CSLD were collected, including six males and eight females, aged (5.9±2.7) years old.Among 14 cases of CSLD, six cases were diagnosed with upper airway cough syndrome, three cases with upper airway cough syndrome and bronchial asthma, two cases with cough variant asthma, and one case with combined immunodeficiency disease.There were different degrees of purulent inflammation under electronic fiber bronchoscopy, and three cases had airway inflammatory stenosis.The lavage fluid suggested neutrophil inflammation.Blood gas analysis was normal in ten cases and hypoxemia in four cases.In seven cases, pulmonary function examination was abnormal in six cases, and one case had emphysema on lung CT examination.After intravenous administration of antibiotics and sequential oral antibiotics, the symptoms of 14 children were relieved.Fourteen cases were followed up for 12 weeks.Among them, 12 cases had complete relief of clinical symptoms, one case had repeated cough with combined immunodeficiency disease, and one case was lost to follow-up.Conclusion:CSLD mostly has primary disease.Electronic fiber bronchoscopy is not only a necessary examination of CSLD, but also one of the important means for treatment.Purulent inflammation of the airways can lead to abnormal obstructive lung.Sufficient course of treatment and standardized use of antibiotics are the key to the treatment for CSLD.

Objective: To investigate the feasibility of cine three-dimensional (3D) balanced steady-state free precession (b-SSFP) imaging combined with a non-local means (NLM) algorithm for image denoising in evaluating cardiac function in children with repaired tetralogy of Fallot (rTOF). Materials and Methods: Thirty-five patients with rTOF (mean age, 12 years; range, 7–18 years) were enrolled to undergo cardiac cine image acquisition, including two-dimensional (2D) b-SSFP, 3D b-SSFP, and 3D b-SSFP combined with NLM. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) of the two ventricles were measured and indexed by body surface index. Acquisition time and image quality were recorded and compared among the three imaging sequences. Results: 3D b-SSFP with denoising vs. 2D b-SSFP had high correlation coefficients for EDV, ESV, SV, and EF of the left (0.959– 0.991; p < 0.001) as well as right (0.755–0.965; p < 0.001) ventricular metrics. The image acquisition time ± standard deviation (SD) was 25.1 ± 2.4 seconds for 3D b-SSFP compared with 277.6 ± 0.7 seconds for 2D b-SSFP, indicating a significantly shorter time with the 3D than the 2D sequence (p < 0.001). Image quality score was better with 3D b-SSFP combined with denoising than with 3D b-SSFP (mean ± SD, 3.8 ± 0.6 vs. 3.5 ± 0.6; p = 0.005). Signal-to-noise ratios for blood and myocardium as well as contrast between blood and myocardium were higher for 3D b-SSFP combined with denoising than for 3D b-SSFP (p < 0.05 for all but septal myocardium). Conclusion The 3D b-SSFP sequence can significantly reduce acquisition time compared to the 2D b-SSFP sequence for cine imaging in the evaluation of ventricular function in children with rTOF, and its quality can be further improved by combining it with an NLM denoising method.

Objective:To evaluate the feasibility of cardiac MRI three dimensional (3D) balanced steady state free precession (b-SSFP) cine imaging in evaluating cardiac function in children with repaired tetralogy of Fallot (TOF).Methods:Thirty children with repaired TOF underwent cardiac MRI examination at Shanghai Children′s Medical Cent er Affiliated to Shanghai Jiao Tong University School of Medicine, were retrospectively collected from April 2018 to October 2019. From June 2017 to August 2018, 10 healthy children were enrolled. Cardiac images of subjects were obtained using both two dimensional (2D) b-SSFP and 3D b-SSFP cardiac cine MRI and the total acquisition time was recorded. The image quality was scored using a 5-point scale, with a score≥3 as diagnostic image quality. The left and right ventricular end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), cardiac output (CO), and cardiac index (CI) were measured. The left and right ventricle parameters were compared using paired ttest or Wilcoxon test. The Pearson correlation or Spearman correlation analysis were used to evluate the correlation between the parameters measured with the 2 methods. Results:The acquisition time of 2D b-SSFP images was (426.5±13.0) s, and the total time of 3D b-SSFP images was (24.7±2.5) s. The 2D b-SSFP image quality score was better than 3D b-SSFP, and the differences were statistically significant (TOF patients: Z=-3.879, P<0.001; volunteers: Z=-2.646, P=0.003). All 2D and 3D b-SSFP image quality scores were ≥ 3 points, which can be used for clinical diagnosis. There were no statistically significant differences in cardiac function parameters between two series measurements in both TOF patients and volunteers ( P>0.05). For TOF patients, the left ventricular EDV, ESV, SV, EF, CO and right ventricular EDV, ESV, and SV showed highly positive correlation ( r>0.8, P<0.05). For volunteers, the left ventricular EDV, ESV, SV and right ventricular EDV and SV showed highly positive correlation ( r>0.8, P<0.05). Conclusion:Compared with the 2D b-SSFP sequence, 3D b-SSFP sequence with fairy good image quality can meet the diagnostic requirement and can accurately measure the cardiac function with shorter acquisition time. The 3D b-SSFP has a good application prospect in pediatric cardiac MRI.
