Objective:To explore the clinical characteristics and pathogenic variant in a child with Cantú syndrome (CS).Methods:A male who was admitted to the Children′s Hospital Affiliated to Zhengzhou University on February 23, 2022 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and his parents were collected and subjected to whole-exome sequencing (WES). Candidate variant was verified by Sanger sequencing. This study was approved by Medical Ethics Committee of the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-087).Results:The child, a 3-year-and-2-month-old male, was born with hirsutism, with heavy hair all over the body and peculiar facial features. Routine echocardiography 1 month before had discovered atrial septal defect. Sequencing revealed that the child has harbored a heterozygous c. 2438G>C (p.S813T) variant of the ABCC9 gene, which was de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 2438G>C variant was classified as likely pathogenic (PS2+ PM2_Supporting+ PP3). Conclusion:The heterozygous c. 2438G>C variant of the ABCC9 gene probably underlay the pathogenesis of CS in this child.

Wu Liande’s spirit was formed during the development of modern public health in China. It is a unity of the spirit of patriotism, humanitarianism, scientific exploration, and dedication, and a valuable resource and vivid textbook for medical students to carry out professional spirit education. Promoting Wu Liande’s spirit in the new era is not only conducive to inspiring the patriotism of medical students, bravely undertaking the mission of the times, and devoting themselves to the cause of human health, but also conducive to guiding medical students to refine benevolence and skill, and fulfill the sacred oath of medical students. To cultivate the professional spirit of medical students with Wu Liande’s spirit, it is necessary to achieve the "integration of specialized courses and ideological and political education" , promote the collaborative development of ideological and political courses and curriculum ideological and political education, innovate teaching methods and use modern information technology to empower Wu Liande’s spirit to be visualized and expressed, and take discipline practice as the starting point to expand the new path of professional spirit practice education for medical students.

OBJECTIVE: To explore the clinical phenotype and genetic features of a child with dilated cardiomyopathy (DCM). METHODS: Clinical data of the child who had presented at the Zhengzhou Children's Hospital on April 28, 2020 was collected. Trio-whole exome sequencing (trio-WES) was carried out for the child and her parents, and candidate variants were validated by Sanger sequencing. "FHL2" was taken as the key word to retrieve related literature from January 1, 1997 to October 31, 2021 in the PubMed database and was also searched in the ClinVar database as a supplement to analyze the correlation between genetic variants and clinical features. RESULTS: The patient was a 5-month-old female infant presented with left ventricular enlargement and reduced systolic function. A heterozygous missense variant c.391C>T (p.Arg131Cys) in FHL2 gene was identified through trio-WES. The same variant was not detected in either of her parents. A total of 10 patients with FHL2 gene variants have been reported in the literature, 6 of them had presented with DCM, 2 with hypertrophic cardiomyopathy (HCM), and 2 with sudden unexplained death (SUD). Phenotypic analysis revealed that patients with variants in the LIM 3 domain presented hypertrophic cardiomyopathy and those with variants of the LIM 0~2 and LIM 4 domains had mainly presented DCM. The c.391C>T (p.Arg131Cys) has been identified in a child with DCM, though it has not been validated among the patient's family members. Based on the guidelines of the American College of Medical Genetics and Genomics, the c.391C>T(p.Arg131Cys) variant was re-classified as likely pathogenic (PS2+PM2_Supporting+PP3+PP5). CONCLUSION The heterozygous missense variant of c.391C>T (p.Arg131Cys) in the FHL2 gene probably predisposed to the DCM in this child, which has highlighted the importance of WES in the clinical diagnosis and genetic counseling.

OBJECTIVE To establish a database of rational drug use for children in our hospital， and to provide reference for ensuring the safety of drug use in children. METHODS The construction and filling of the knowledge base of rational drug use for children were performed by establishing the basic structure of the knowledge base， formulating reference standards for the quality level of pediatric medication evidence， and refining evidence-based evidence of pediatric medication. The rule base of rational drug use for children was designed and built from four aspects： preliminary determination rules for patient information， basic drug information rules， prescription suitability review rules， result labeling and post-processing rules. The database was embedded into prescription review system of our hospital and was applied online to test its effectiveness. RESULTS A set of database containing 672 commonly used pediatric medicines and more than 15 000 rules for rational drug use for children was initially constructed. The average interception rate of unreasonable medical orders for hospitalized children after database application（from December 2021 to May 2022）was 2.03%， and was higher than 0.80% before database application（from June 2021 to November 2021）（χ 2＝5 784.389， P＜0.001）； after post-sampling and prescription review， the average qualified rate of medication orders in discharged medical records for children after the application of the database was 99.10%， and was higher than 94.58% before the application of the database （χ 2＝301.237， P＜0.001）. CONCLUSIONS Self-constructed evidence-based rational drug use database for children is close to the actual clinical needs of pediatrics in medical institutions， which can effectively reduce clinical irrational drug use behaviors in pediatrics， improve the pass rate of prescriptions， and ensure the safety of children’s drug use.

Objective:To investigate the risk factors of non-alcoholic fatty liver disease (NAFLD) in patients with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer (HR+/HER2-BC) and the impact of NAFLD on the survival of patients.Methods:54 HR+BC patients were enrolled in this study. The liver fat accumulation was examined by magnetic resonance imaging (MRI). The patients were divided into two groups: non-NAFLD and NAFLD. Student's t test or Fisher's test was used to analyze the clinical indicators of the two groups. Logistic univariate and multivariate tests were used to analyze the clinical risk factors related to NAFLD. Receiver operating characteristic curve (ROC curve) was used to further analyze the sensitivity of clinical risk factors to predict the diagnosis of NAFLD. The Disease-free survival (DFS) and Overall survival (OS) of the two groups were analyzed by Log-rank (Mantel-Cox) test. Results:There were 22 NAFLD patients and 32 non-NAFLD patients diagnosed by MRI. Student's t test or Fisher's test showed that BMI, waist circumference, AST, ALT, GGT, TG, LDL and HDL were statistically different between the two groups (all P<0.05). Logistic univariate and multivariate analysis showed that AST ( OR=1.05, 95% CI: 1.02-1.10, P=0.007), GGT ( OR=1.04, 95% CI: 1.01-1.09, P=0.038), TG ( OR=1.03, 95% CI: 1.01-1.06, P=0.011) and HDL ( OR=1.06, 95% CI: 1.01-1.12, P=0.037) were the risk factors associated with NAFLD. ROC curve analysis showed that the combination of AST, GGT, TG and HDL had high sensitivity in predicting NAFLD (AUC=0.869, P<0.05). There was no difference in DFS ( HR=1.830, 95% CI: 0.983-3.409, P=0.057) or OS ( HR=2.482, 95% CI: 0.761-8.093, P=0.132) between the two groups. Conclusion:AST, GGT, TG and HDL are the independent risk factors for NAFLD in HR+BC patients during treatment, but concurrent NAFLD has no significant effect on DFS or OS.

OBJECTIVE: To explore the clinical and genetic characteristics of five children with Catecholaminergic polymorphic ventricular tachycardia (CPVT). METHODS: Five children with clinical manifestations consistent with CPVT admitted to the Department of Cardiology of Children's Hospital Affiliated to Zhengzhou University from November 2019 to November 2021 were selected as the study subjects. Their clinical data were collected. Potential variants were detected by whole exome sequencing, and Sanger sequencing was used to verify the candidate variants. All patients were treated with β-blocker propranolol and followed up. RESULTS: All patients had developed the disease during exercise and presented with syncope as the initial clinical manifestation. Electrocardiogram showed sinus bradycardia. The first onset age of the 5 patients were (10.4 ± 2.19) years, and the time of delayed diagnosis was (1.6 ± 2.19) years. All of the children were found to harbor de novo heterozygous missense variants of the RYR2 gene, including c.6916G>A (p.V2306I), c.527G>C (p.R176P), c.12271G>A (p.A4091T), c.506G>T (p.R169L) and c.6817G>A (p.G2273R). Among these, c.527G>C (p.R176P) and c.6817G>A (p.G2273R) were unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c.527G>C (p.R176P) was classified as a pathogenic variant (PS2+PM1+PM2_Supporting+PM5+PP3+PP4), and the c.6817G>A (p.G2273R) was classified as a likely pathogenic variant (PS2+PM2_Supporting+PP3+PP4). The symptoms of all children were significantly improved with the propranolol treatment, and none has developed syncope during the follow up. CONCLUSION Discovery of the c.527G>C (p.R176P) and c.6817G>A (p.G2273R) variants has expanded the mutational spectrum of the RYR2 gene. Genetic testing of CPVT patients can clarify the cause of the disease and provide a reference for their genetic counseling.

OBJECTIVE: To analyze the clinical and genetic characteristics of a child with restricted cardiomyopathy (RCM) and phenylketonuria (PKU), and summarize the clinical characteristics and genetic diversity of RCM in children through a literature review. METHODS: A child with RCM in conjunct with PKU who was admitted to the Children's Hospital Affiliated to Zhengzhou University in June 2020 due to edema of eyelids and lower limbs for 1 year and aggravation for over 1 month was selected as the study subject. Relevant clinical data were collected. Peripheral blood samples of the child and his parents were collected for whole exome sequencing (WES). Candidate variants were validated by Sanger sequencing and bioinformatic analysis. Childhood, TNNI3 gene and restricted cardiomyopathy were used as the keywords to search the Wanfang data knowledge service platform, Chinese Journal Full-text database and PubMed database, and the search period was limited to from the time of establishment till August 2022. Clinical manifestations and characteristics of the TNNI3 gene variants were summarized. RESULTS: The child, a 2-year-old-and-4-month-old male, had normal intelligence, facial features and normal hair and skin color, but his motor and physical development was delayed, in addition with edema of bilateral eyelids and lower limbs. The results of WES and Sanger sequencing revealed that he has harbored compound heterozygous variants of the PAH gene, namely c.331C>T (p.R111X) and c.940C>A (p.P341T), which were inherited from his father and mother, respectively. In addition, he has also harbored a de novo heterozygous variant of c.508C>T (p.R170W) of the TNNI3 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the TNNI3: c.508C>T (p.R170W) was classified as a pathogenic variant (PS2+PS4+PM2_Supporting+PM5), PAH: c.331C>T (p.R111X) as a pathogenic variant (PVS1+PM2_Supporting+PM3+PP4), and c.940C>A (p.P341T) as a likely pathogenic variant (PM2_Supporting+PM3+PM5+PP4). In total 30 children with RCM caused by TNNI3 gene variants were retrieved, with a male-to-female ratio of 1 : 1.55 and manifestations including heart failure, sinus rhythm, bi-atrial enlargement, ST-T wave change, ventricular restricted filling, and decreased ventricular diastolic function. In total 16 variants of the TNNI3 gene were identified, among which c.575G>A was the most common, and all cases had conformed to an autosomal dominant inheritance. CONCLUSION Phenylalanine hydroxylase deficiency and RCM are rare diseases with complex clinical manifestations. The PAH: c.331C>T (p.R111X)/c.940C>A (p.P341T) and TNNI3: c.508C>T (p.R170W) variants probably underlay the RCM and PKU in this child.

OBJECTIVE: To explore the clinical and genetic characteristics of eight children with Primary hypertrophic cardiomyopathy (HCM). METHODS: Eight children with HCM admitted to the Department of Cardiology of Henan Children's Hospital from January 2018 to December 2021 were selected as the study subjects. Clinical data of the children were collected. Whole exome sequencing was carried out on two children, and trio whole exome sequencing was carried out on the remainder 6 children. Sanger sequencing was used to verify the candidate variants in the children and their parents, and the pathogenicity of the variants was evaluated based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). RESULTS: The patients had included 5 males and 3 females, with their ages ranging from 5 to 13 years old. The average age of diagnosis was (7.87 ± 4.8) years old, and the cardiac phenotype showed non-obstructive HCM in all of the patients. WES has identified variants of the MYH7 gene in 4 children, including c.2155C>T (p.Arg719Trp), c.1208G>A (p.Arg403Gln), c.1358G>A (p.Arg453His), and c.1498G>A (p.Glu500Lys). Based on the guidelines from the ACMG, the first 3 variants were classified as pathogenic, while c.1498G>A (p.Glu500Lys) was classified as likely pathogenic (PM1+PM2_Supporting+PM6+PP3), which was also unreported previously. The remaining four children had all harbored maternal variants, including MYL2: c.173G>A (p.Arg58Gln; classified as pathogenic), TPM1: c.574G>A (p.Glu192Lys) and ACTC1: c.301G>A (p.Glu101Lys)(both were classified as likely pathogenic), and MYBPC3: c.146T>G (p.Ile49Ser; classified as variant of uncertain significance). Seven children were treated with 0.5 ~ 3 mg/(kg·d) propranolol, and their symptoms had improved significantly. They were followed up until September 30, 2022 without further cardiac event. CONCLUSION Genetic testing can clarify the molecular basis for unexplained cardiomyopathy and provide a basis for clinical diagnosis and genetic counseling. Discovery of the c.1498G>A (p.Glu500Lys) variant has also expanded the spectrum of MYH7 gene mutations underlying HCM.
