The contents recorded in the rotation registration manual is not only the quantitative indicators for evaluating the quality of residency training, but also the important basis for training assessment and issuance of training certificates. In order to solve the problems of data authenticity, information delay, and repeated entry in the rotation registration manual for residency training, Shanghai East Hospital, Tongji University, launched a project to dock the electronic rotation registration manual with the hospital information system. Through the establishment of the project team, the development of working mechanisms, and the implementation of the project, data analysis was used for process reformation and system optimization, so as to continuously improve management efficiency and medical safety while solving problems and form a set of implementation system with reference significance in practice.

Allergic conjunctivitis is the most common type of allergic eye disease, and the incidence in children and adolescents is increasing year by year. Drug therapy can only relieve some symptoms and only in a short period, while allergen immunotherapy is currently a therapy that can significantly improve the symptoms of chronic allergy and the course of the disease. This method has been used abroad for many years but has yet to be reported in China. The author reviews the effective mechanism and clinical efficiency of allergen immunotherapy and provides a reference for the further clinical application in China.

Objective:To investigate the clinical and genetic characteristics of children with 45, X/46, XY mosaicism.Methods:The retrospective study included 20 children diagnosed with 45, X/46, XY and 45, X/46, X,+mar mosaicism in the First Affiliated Hospital of Zhengzhou University from 2018 to 2022. The clinical features, gonadal pathology, treatment and follow-up were summarized. Genetic tests were performed by SRY gene test, azoospermia factor region (AZF) deletion test, copy number variation-sequencing (CNV-seq). Age at first diagnosis was compared between boys and girls using independent sample t-test. Results:The 20 patients included 3 boys and 17 girls, and the age at first diagnosis were (7.6±5.5) years, it is (2.1±1.9) years in boys, (8.7±5.4) years in girls, significantly younger for boys ( t=-3.86, P=0.004). The chief complaint was external genitalia malformation for boys, and short stature (13 cases) and dysplastic external genital for girls (4 cases). Five girls presented with features of Turner syndrome. The gonadal phenotypes included mixed gonadal dysplasia (MGD, 6 cases), complete gonadal dysplasia (CGD, 10 cases), unilateral ovotestis (2 cases), possible ovaries (1 case) and undetermined gonad (1 case). One female with dysplastic genital was reassigned to male, and the gender of the remaining cases remained unchanged. Seven females were treated with recombinant human growth hormone. The height increased by (17±7) cm during the (2.9±1.2) years follow-up. No gonadal malignancy was observed. The karyotype was 45, X/46, XY in 16 cases, and 45, X/46, X,+mar in 4 cases. All of the 4 marker chromosomes were derived from Y chromosome confirmed by CNV-seq. SRY gene was detected in all 20 patients genome, and AZF deletion was found in 7 girls. Conclusions:45, X/46, XY mosaicism presented with dysplastic external genital or female with remarkable short stature. Gonadal phenotypes included MGD, CGD and ovotestis. AZF microdeletions were found in the majority of female cases.

OBJECTIVE: To assess the value of copy number variation sequencing (CNV-seq) for the diagnosis of children with disorders of sex development (DSD). METHODS: Five children with DSD who presented at the First Affiliated Hospital of Zhengzhou University from October 2019 to October 2020 were enrolled. In addition to chromosomal karyotyping, whole exome sequencing (WES), SRY gene testing, and CNV-seq were also carried out. RESULTS: Child 1 and 2 had a social gender of female, whilst their karyotypes were both 46,XY. No pathogenic variant was identified by WES. The results of CNV-seq were 46,XY,+Y (1.4) and 46,XY,-Y (0.75), respectively. The remaining three children have all carried an abnormal chromosome Y. Based on the results of CNV-seq, their karyotypes were respectively verified as 45,X[60]/46,X,del(Y)(q11.221)[40], 45,X,16qh+[76]/46,X,del(Y)(q11.222),16qh+[24], and 45,X[75]/46,XY[25]. CONCLUSION CNV-seq may be used to verify the CNVs on the Y chromosome among children with DSD and identify the abnormal chromosome in those with 45,X/46,XY. Above results have provided a basis for the clinical diagnosis and treatment of such children.

OBJECTIVE: To assess the value of copy number variation sequencing (CNV-seq) for revealing the genetic etiology of fetuses with isolated ventricular septal defect (VSD). METHODS: From December 2017 to December 2020, 69 fetuses with isolated VSD were identified at the First Affiliated Hospital of Zhengzhou University. Meanwhile, 839 similar prenatal cases were selected from public databases including Wanfang data, Wanfang Medicine, and China National Knowledge Infrastructure (CNKI) by using keywords such as "Ventricular septal defect", "Copy number variation", and "Prenatal". A total of 908 fetuses with isolated VSD were analyzed. CNV-seq was carried out for 69 fetuses. RESULTS: Among the 908 fetuses, 33 (3.63%) were found to harbor pathogenic CNVs, which included 11 chromosomal aneuploidies (1.21%) and 22 pathogenic CNVs (2.42%). The pathogenic CNVs have involved 12 genetic syndromes, with those known to involve the heart development including 5 cases of 22q11.21 deletion syndrome, 2 cases of 4q terminal deletion syndrome, and 1 case of 9q subtelomere deletion syndrome. The outcome of pregnancies for 15 fetuses with pathogenic CNVs was known, of which 12 were terminated, and 3 had spontaneous closure of the ventricular septum after birth, but 1 of them had other abnormalities. CONCLUSION Fetuses with isolated VSD have a relatively high risk for chromosomal abnormalities, for which CNV-seq should be recommended.

OBJECTIVE: To carry out genetic testing and prenatal diagnosis for a woman featuring moderate intellectual disability (ID). METHODS: The patient had presented at the First Affiliated Hospital of Zhengzhou University on April 28, 2021. With informed consent, peripheral blood and amniotic fluid samples were collected for the extraction of genomic DNA. Pathogenic copy number variations (CNVs) were detected with CNV-seq, and single gene variants were detected by whole exome sequencing (WES) and Sanger sequencing. Candidate variant was verified by Sanger sequencing, and CNV-seq and multiplex ligation-dependent probe amplification (MLPA) were used to detect fetal CNVs. RESULTS: The 23-year-old woman had moderate ID, sideway walking, and unstable holding. Ultrasonography at 18⁺³ weeks' gestation had revealed no fetal abnormality. No pathogenic CNV was detected in the woman by CNV-Seq, while WES revealed that she has harbored a heterozygous c.1675C>T (p.Arg559*) variant of the DLG4 gene, which was verified by Sanger sequencing. Based on guidelines from the American College of Medical Genetics and Genomics, the variant was predicted to be likely pathogenic (PVS1+PM2_supporting). Sanger sequencing has confirmed that the fetus has inherited this variant, and CNV-Seq also revealed that that fetus has harbored a 0.1 Mb heterozygous deletion at Xp21.1, which has encompassed the DMD gene, and the result was verified by MLPA. CONCLUSION The heterozygous c.1675C>T variant of the DLG4 gene probably underlay the mental retardation in this woman, and her fetus was found to harbor the same variant in addition with deletion of the DMD gene, which may predispose to ID type 62.

OBJECTIVE: To explore the genetic basis for a rare case with Disorder of sex development. METHODS: Clinical data of the patient was collected. Chromosomal karyotyping, SRY gene testing, whole exome sequencing (WES), low-coverage massively parallel copy number variation sequencing (CNV-seq), fluorescence in situ hybridization (FISH), and whole genome sequencing (WGS) were carried out. RESULTS: The patient, a 14-year-old female, had manifested short stature and dysplasia of second sex characteristics. She was found to have a 46,XY karyotype and positive for the SRY gene. No pathogenic variant was found by WES, except a duplication at Yp11.32q12. The result of CNV-seq was 47,XYY. FISH has confirmed mosaicism for a dicentric Y chromosome. A 23.66 Mb duplication on Yp11.32q11.223 and a 5.16 Mb deletion on Yq11.223q11.23 were found by WGS. The breakpoint was mapped at chrY: 23656267. The patient's karyotype was ultimately determined as 46,X,psu idic(Y)(q11.223)/46,X,del(Y)(q11.223). CONCLUSION The combination of multiple methods has facilitated clarification of the genetic etiology in this patient, which has provided a reference for the clinical diagnosis and treatment.

The paper reports two cases of lipoprotein glomerulopathy (LPG) in children. The Sanger sequencing results in 2 cases indicated apolipoprotein E gene mutation[c.127 (exon3) C>T, p.R43C (p.Arg43Cys); c.494 (exon4) G>C, p.R165P (p.Arg165Pro),respectively]. Renal pathological presentation of two children showed that a large number of lipoprotein emboli were formed in the glomerular capillary loop, and the diagnosis of LPG was confirmed. The onset of LPG has no specific clinical manifestation, which is easy to be undiagnosed or misdiagnosed. Renal biopsy is a diagnostic means, glucocorticoid treatment is ineffective, and long-term lipid-lowering treatment may be required for LPG.

Objective:To analyze the long-term prognosis of IgA nephropathy (IgAN) with focal segmental glomerulosclerosis (FSGS) and the risk factors related to renal prognosis in children with IgAN-FSGS.Methods:A retrospective study was concluded in IgAN-FSGS children who were followed up for more than 5 years and diagnosed by renal biopsy for the first time in the Eastern Theater General Hospital from January, 2004 to December, 2018. The end-point events of the study were entering end-stage kidney disease (ESKD) or estimated glomerular filtration rate (eGFR) decreased by ≥50% from baseline, which were defined as poor renal prognosis. Baseline clinicopathologic data of IgAN-FSGS children were compared between the end-point event group and the non-end-point event group. The cumulative renal survival rate of IgAN-FSGS children was calculated by Kaplan-Meier survival analysis. The influencing factors of poor renal prognosis in IgAN-FSGS children were analyzed by Cox proportional hazards model, and the diagnostic value was evaluated by the receiver operating characteristic curve (ROC curve) and area under the curve (AUC). The diagnostic value was verified by time dependent-ROC and time dependent-AUC.Results:A total of 204 IgAN-FSGS children were enrolled in this study, of whom 132 cases were males (64.7%). The median age of renal biopsy was 16 (14, 17) years old. During a median follow-up time of 90.7 (71.7, 114.8) months, 57 cases (27.9%) reached the end-point events. Compared with the non-end-point event group ( n=147), the end-point event group ( n=57) had higher proportions of males and hypertension, higher levels of 24-hour urinary protein, serum creatinine, serum uric acid, urinary N-acetyl-β- D-glucosaminidase, urinary retinol binding protein, higher proportions of glomerular segmental sclerosis (S1) ≥25% and tubular atrophy/interstitial fibrosis (T1/T2), and lower levels of serum albumin, serum IgA, and serum IgG (all P<0.05). There was no statistical difference between the two groups in treatment (all P>0.05). Kaplan-Meier survival analysis showed that with entry of ESKD or eGFR decreased by ≥50% from baseline as the end-point events, the 5-year, 10-year, and 15-year cumulative renal survival rates in IgAN-FSGS children were 88.7%, 67.6%, and 50.7%, respectively. Multivariate Cox regression analysis showed that proteinuria >1 g/24 h ( HR=3.702, 95% CI 1.657-8.272, P=0.001), hyperuricemia ( HR=3.066, 95% CI 1.793-5.245, P<0.001), S1≥25% ( HR=2.017, 95% CI 1.050-3.874, P=0.035), T1/T2 ( HR=1.863, 95% CI 1.021-3.158, P=0.016) were the independent related factors for poor renal prognosis. ROC curve analysis showed that S1≥25% ( AUC=0.605, P=0.021, sensitivity 26.3%, specificity 94.6%), T1/T2 ( AUC=0.624, P=0.006, sensitivity 43.9%, specificity 81.0%), hyperuricemia ( AUC=0.658, P<0.001, sensitivity 52.6%, specificity 78.9%), proteinuria>1 g/24 h ( AUC=0.670, P<0.001, sensitivity 87.7%, specificity 46.3%) could accurately predict the renal outcome of IgAN-FSGS. Time dependent-ROC curve validation showed that the combined diagnosis of S1≥25%, T1/T2, hyperuricemia and proteinuria>1 g/24 h had a good predictive value for renal prognosis (3-year AUC=0.846 and 5-year AUC=0.777, respectively). Conclusions:During a median follow-up of 90.7 months, 27.9% of IgAN-FSGS children have poor renal prognosis, and the 5-year, 10-year, and 15-year cumulative renal survival rates are 88.7%, 67.6%, and 50.7%, respectively. Urinary protein >1 g/24 h, hyperuricemia, T1/T2, and S1 ≥25% are the risk factors for renal prognosis in IgAN-FSGS children.
