Objective To determine the scores of patients with a confirmed diagnosis of drug-induced liver injury(DILI)using Roussel Uclaf Causality Assessment Method(RUCAM),Maria&Victorino assessment scale,and Revised Electronic Causality Assessment Method(RECAM),to compare the accuracy of the three scales in diagnosis,and to investigate their clinical significance in the diagnosis of DILI.Methods A total of 98 patients with a confirmed diagnosis of DILI who were hospitalized in Peking University First Hospital from January 2011 to December 2022 were enrolled,with liver biopsy results supporting DILI and a clear history of medication.Clinical data were collected from all subjects,and the above causality assessment scales were used for scoring.The chi-square test was used to analyze the diagnostic accuracy of the causality assessment scales,and the weighted kappa coefficient was used to analyze the consistency between the three scales.Results For all patients with DILI enrolled,RECAM had the highest accuracy,with a significant difference compared with RUCAM(χ2=5.667,P=0.017).RUCAM and RECAM had moderate consistency in diagnosis(κw=0.469),while RECAM and Maria&Victorino scale had poor consistency(κw=0.156).For the patients with acute DILI,RECAM,RUCAM,and Maria&Victorino scales had a diagnostic inconsistency rate of 3.7%,11.1%,and 42.6%,respectively;for the patients with hepatocellular type DILI,the three scales of a diagnostic inconsistency rate of 8.9%,21.4%,and 62.5%,respectively;for the patients with cholestasis type or mixed type DILI,the three scales of a diagnostic inconsistency rate of 10.0%,22.5%,and 47.5%,respectively.Conclusion The use of RECAM and RUCAM scales in acute DILI can improve diagnostic rate,and for hepatocellular type DILI and DILI with the clinical manifestation of cholestasis(cholestasis type DILI and mixed type DILI),the use of RECAM and RUCAM scales can also improve diagnostic rate.The selection of causality assessment scales with a relatively high accuracy based on the course and clinical classification of the disease may help to further improve clinical diagnostic rate.

Objective:To analyze the clinical and genetic characteristics of a child featuring Dias-Logan syndrome.Methods:A child with speech disorders and delayed psychomotor development from childhood who was admitted to the Rehabilitation Medicine Department of Children′s Hospital Affiliated to Zhengzhou University in July 2022 was selected as the research subject. Clinical data of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his parents. Potential variant was screened by whole exome sequencing, and candidate variant was verified by Sanger sequencing. This study was approved by the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-011).Results:The child has presented with global developmental delay, microcephaly, special facial features and behavioral problems. Genetic testing revealed a de novo variant of the BCL11A gene, namely c. 561_567delACACGCA(p.Q187fs*7), which was classified as pathogenic (PVS1+ PS2+ PM2_Supporting). Conclusion:The heterozygous variant of BCL11A gene probably underlay the Dias-Logan syndrome in this child. Above finding has enriched the phenotypic and mutational spectrum of the BCL11A gene and provides a basis for genetic counseling and clinical decision-making.

Objective:To investigate the clinical and genetic features of the patient with neurodevelopmental disorders characterized by thickened corpus callosum caused by MAST1 gene mutation. Methods:Clinical data and auxiliary examination of a child with neurodevelopmental disorders caused by MAST1 gene mutation who was admitted to Henan Children′s Hospital in September 2022 were collected, and whole exome sequencing technology was applied to analyze the genetics of the child. Results:The patient was a 2 years and 8 months old male, with a clinical phenotype including intellectual, motor, and speech development disorders. Brain magnetic resonance imaging (MRI) showed thickened corpus callosum, nodular heterotopia of the left ventricle body.Whole exome sequencing showed the MAST1 gene with c.578T>G(p.Met193Arg) heterozygous missense variant, which was a unreported de novo pathogenic variant and both of his parents were wild-type. Conclusions:Diseases caused by MAST1 gene mutations are relatively rare, the main clinical features are neurodevelopmental disorders and brain structural abnormalities, and MRI shows an enlarged corpus callosum.The heterozygous missense variant c.578T>G(p.Met193Arg) of the MAST1 gene is the genetic cause of this case.

OBJECTIVE: To analyze the clinical phenotype and genetic variant in a child with Raynaud-Claes syndrome (RCS). METHODS: A child who was diagnosed with RCS at the Children's Hospital Affiliated to Zhengzhou University for delayed language and motor development in August 2022 was selected as the study subject. Clinical data of the child were collected, and potential genetic variant was detected by next-generation sequencing and Sanger sequencing. The pathogenicity of the candidate variant was analyzed. RESULTS: The child, a 4-year-and-4-month-old male, has manifested global developmental delay, speech disorders, special facial features and behavioral abnormalities. Genetic testing revealed that he has harbored a hemizygous c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene, which was not detected in either of his parents. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PVS1+PS2+PM2_Supporting). CONCLUSION The c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene probably underlay the PCS in this child. Above finding has expanded the mutational spectrum of the CLCN4 gene and enabled genetic counseling and prenatal diagnosis for his family.

Objective:To evaluate the feasibility and clinical value of pre-treatment non-enhanced chest CT radiomics features and machine learning algorithm to predict the mutation status and subtype (19Del/21L858R) of epidermal growth factor receptor (EGFR) for patients with non-small cell lung cancer (NSCLC).Methods:This retrospective study enrolled 280 NSCLC patients from first and second affiliated hospital of University of South China who were confirmed by biopsy pathology, gene examination, and have pre-treatment non-enhanced CT scans. There are 136 patients were confirmed EGFR mutation. Primary lung gross tumor volume was contoured by two experienced radiologists and oncologists, and 851 radiomics features were subsequently extracted. Then, spearman correlation analysis and RELIEFF algorithm were used to screen predictive features. The two hospitals were training and validation cohort, respectively. Clinical-radiomics model was constructed using selected radiomics and clinical features, and compared with models built by radiomics features or clinical features respectively. In this study, machine learning models were established using support vector machine (SVM) and a sequential modeling procedure to predict the mutation status and subtype of EGFR. The area under receiver operating curve (AUC-ROC) was employed to evaluate the performances of established models.Results:After feature selection, 21 radiomics features were found to be efffective in predicting EGFR mutation status and subtype and were used to establish radiomics models. Three types models were established, including clinical model, radiomics model, and clinical-radiomics model. The clinical-radiomics model showed the best predictive efficacy, AUCs of predicting EGFR mutation status for training dataset and validation dataset were 0.956 (95% CI: 0.952-1.000) and 0.961 (95% CI: 0.924-0.998), respectively. The AUCs of predicting 19Del/L858R mutation subtype for training dataset and validation dataset were 0.926 (95% CI: 0.893-0.959), 0.938 (95% CI: 0.876-1.000), respectively. Conclusions:The constructed sequential models based on integration of CT radiomics, clinical features and machine learning can accurately predict the mutation status and subtype of EGFR.

Objective:To construct and implement a multidisciplinary pain management model during the perioperative period based on the project-achieving quality control circle, so as to improve the quality of patient pain management during the perioperative period.Methods:Using the convenient sampling, 310 surgical patients from the Department of Gastrointestinal Surgery, Hepatobiliary Surgery, Thoracic Surgery, Urology Surgery and Joint Surgery of Liaocheng People's Hospital from June to July 2020 were taken as the pre-improvement group, and the routine perioperative pain management model was implemented.

OBJECTIVE: To investigate the mental health status and its influencing factors among general population and healthcare professionals in Guangdong Province during COVID-19 pandemic. METHODS: A online questionnaire-based survey was conducted from March 11st to March 15th, 2020.The questionnaire consisted of 4 parts to survey the participants'basic information, understanding of COVID-19 outbreak-associated information, cognition of COVID-19 pandemic and status of anxiety and depression.A total of 1433 valid responses were collected, including 706 from the general population and 727 from healthcare professionals.Cronbach's α coefficient and exploratory factor analysis were used for reliability and validity assessment.Chi-square, Wilcoxon and Kruskal-Wallis test were used for univariate analysis and ordinal or nominal logistic regression was used for multivariate analysis of the data. RESULTS: There was no significant difference between the general population and the healthcare professionals in terms of anxiety, depression and cognition of COVID-19 outbreak after adjustment for demographic variables, but the levels of anxiety and depression of these participants were both higher than those before the pandemic.In the participants from the general population, multivariate logistic regressions showed an OR for anxiety of 1.93(1.18, 3.17) among those who spent 1-2 h a day in reading COVID-19-related news, while those who spent over 3 h had an OR value for anxiety of 1.88(1.14, 3.11);the unmarried individuals had a depression OR of 2.19(1.51, 3.18). Inaccurate cognition of COVID-19 outbreak was positive correlated with the occurrence of anxiety and depression.Unmarried individuals and those with higher educational levels had better cognition of COVID-19 outbreak.Among the healthcare professionals, multivariate logistic regressions suggested that insufficient rest time and worries about contracting the virus contributed to the occurrence of anxiety and depression.Among the nursing staff, the OR of obvious depression was 2.99(1.45, 6.18).Compared to healthcare professionals not working in designated hospital for COVID-19, those who work in the designated hospitals had ORs for obvious and severe depression of 0.48(0.25, 0.93) and 0.39(0.17, 0.89), respectively.Concerns over contracting the virus increased the possibility of incorrect cognition of COVID-19. CONCLUSIONS Psychological interventions are essential for both the general population and healthcare professionals, especially for unmarried individuals in the general population and the nursing staff.An excessive exposure to COVID-19-related information may have detrimental effects on the mental health.For healthcare professionals, sufficient rest needs to be ensured, and education programs on COVID-19 should be implemented among both residents and healthcare professionals to improve their mental health.
