erence regarding the qualified rate of food allergy knowledge among the trainees before training (45.5% (20/44)), at the end of training (78.0% (46/59)) and two months after training (13/14) (χ(2)=16.8, P less then 0.01). Conclusions The knowledge of food allergy on diagnosis and management among Chinese pediatric medical workers is unsatisfactory. Targeted offline training could continuously improve the level of diagnosis and treatment in a long period.Objective To analyze clinical features, prognosis and risk factors of bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH). click here Methods Clinical data of 338 infants with BPD were collected from the neonatal intensive care unit (NICU) in Shenzhen Maternity and Child Healthcare Hospital, Southern Medical University between January 2016 and December 2018. These infants were divided into PH group and non-PH group. The clinical features and prognosis were compared between these two groups by Chi-square test or nonparametric test. Risk factors for BPD-PH were analyzed with binary logistic regression model. Results Among the 338 BPD infants, 314 had no PH (92.9%) and 24 had PH (7.1%), with an average gestational age of (27.1±1.8) weeks, and 206 were males and 132 females.PH infants had younger gestational age ((26.4±2.1) vs. (27.2±1.7) weeks, t=2.201, P=0.028) and lower birth weight ((798±255) vs. (1 003±240) g, t=4.030, P less then 0.01), compared to non-PH infants. Besides, duration of mechanical vesia (OR=10.160, 95%CI 2.725-37.884), SGA (OR=4.992, 95%CI 1.432-16.920), PDA requiring ligation (OR=19.802, 95%CI 3.297-118.921), severe EUGR (OR=20.316, 95%CI 2.221-185.853) were independent risk factors of BPD associated PH. In the 24 infants with PH, all 7 mild PH infants and 8 moderate PH infants survived, while 4 out of 9 severe PH infants died. Among the survivors, the longest duration of oxygen therapy was up to the corrected gestational age of 1 year and 2 months. Conclusions PH is a severe complication of BPD, and associated with higher mortality and poor prognosis. Echocardiography screening and regular post-discharge follow up are recommended for BPD infants with risk factors of PH.Objective To study and formulate the growth standards for birth weight, length and head circumference of Chinese newborns of different gestation. Methods A cross-sectional survey was carried out by the stratified cluster sampling method from June 2015 to November 2018 in 13 cities including Beijing, Harbin, Xi'an, Shanghai, Nanjing, Wuhan, Guangzhou, Fuzhou, Kunming, Tianjin, Shenyang, Changsha and Shenzhen. A total of 24 375 newborns with gestational age between 24 to 42 weeks were included. The standard percentile-curves of birth weight, length and head circumference for newborn boys and girls in gestational weeks 24 to 42 were established by the generalized additive model for location, scale and shape (GAMLSS). The new reference standard developed in this study was compared with the reference values of China in 1988 and the international Fenton 2013. Results Among the 24 375 newborns (13 197 males (54.1%),11 178 females (45.9%)), 12 264 were preterm infants and 12 111 were full term infants. The 3(rd), 10(, respectively.Objective To analyze the consistency of the clinical phenotype of Alport syndrome between monozygotic twins. Methods This retrospective study included identical twins with Alport syndrome who met the inclusion and exclusion criteria and were admitted to Peking University First Hospital from January 2000 to March 2019. Their clinical data and urinary epidermal growth factor (uEGF) level were extracted from the on-line registry system of hereditary kidney diseases, and analyzed retrospectively. Results Three pairs of monozygotic twins with X-linked Alport syndrome from three non-consanguineous families were included. The consistency of the genotype status between the twins tended to confirm their monozygotic relationship. The first twins were term infants, and the twin 1A had a normal birth weight (2 500 g) while twin 1B was small for gestational age (2 450 g) . The other two pairs of twins were preterm, with different birth weights between twins 2 (2A is 2 450 g, 2B is 1 900 g) , but similar birth weights betwcoustic abnormalities were similar between the twins. Twins 2 and 3 showed bilateral temporal retinal thinning, and twins 1 both had binaural mild mid-low frequency sensorineural deafness. Conclusions Renal manifestations of X-linked Alport syndrome in monozygotic twins may differ from each other, whereas the extrarenal manifestations including ocular and acoustic abnormalities may be consistent. Low birth weight and growth retardation may be associated with the progression of renal dysfunction.Objective To investigate the predictive factors of poor prognosis in children with acute kidney injury (AKI) treated with renal replacement therapy (RRT). Methods In this retrospective case-control study, the clinical data were collected from 134 pediatric patients (82 male, 52 female) with AKI treated with RRT in six tertiary hospitals from May 2015 to June 2018. According to the serum creatinine level at discharge, the patients were divided into the favorable outcome group and unfavorable outcome group. The data of sex, age, primary diseases, AKI stage, time from diagnosis of AKI to start of RRT (h) and whether to start RRT within 24 hours, urine volume and complications between the two groups were compared. Continuous variables were compared by t test and Mann-Whitney U test, and percentage or proportions were compared by Chi square test. The predictive factors of adverse prognosis were analyzed by using univariate and unconditional binary logistic regression analysis. Results The average age of the 134 AK(2)=6.365, P=0.041) were higher than those in the favorable outcome group. Logistic regression analysis showed that mechanical ventilation (OR=12.540, 95%CI 3.376-46.577, P less then 0.01) and hyperkalemia (OR=4.611, 95%CI 1.265-16.805, P=0.021) were the predictive factors of poor prognosis in patients with AKI treated with RRT. Conclusion Mechanical ventilation and hyperkalemia may predict a poor prognosis in AKI patients treated with RRT.
