Objective: To discuss the clinical and genetic features of intellectual developmental disorder with behavioral abnormalities and craniofacial dysmorphism with or without seizures (IDDBCS). Methods: The clinical and genetic records of a patient who was diagnosed with IDDBCS caused by PHF21A gene variation at Children's Hospital Capital Institute of Pediatrics in 2021 were collected retrospectively. Using " PHF21A gene" as the keyword, relevant articles were searched at CNKI, Wanfang Data and PubMed from establishment of databases to February 2023. Clinical and genetic features of IDDBCS were summarized in the combination of this case. Results: An 8 months of age boy showed overgrowth (height, weight and head circumference were all higher than the 97^th percentile of children of the same age and sex) and language and motor developmental delay after birth, and gradually showed autism-like symptoms like stereotyped behavior and poor eye contact. At 8 months of age, he began to show epileptic seizures, which were in the form of a series of spastic seizures with no reaction to adrenocorticotropic hormone but a good response to vigabatrin. Physical examination showed special craniofacial appearances including a prominent high forehead, sparse eyebrows, broad nasal bridge, and downturned mouth with a tent-shaped upper lip. The patient also manifested hypotonia. Whole exome sequencing showed a de novo heterogeneous variant, PHF21A (NM_001101802.1): c.54+1G>A, and IDDBCS was diagnosed. A total of 6 articles (all English articles) were collected, involving this case and other 14 patients of IDDBCS caused by PHF21A gene variation. Clinical manifestations were intellectual disability or developmental delay (15 patients), craniofacial anomalies (15 patients), behavioral abnormalities (12 patients), seizures (9 patients), and overgrowth (8 patients). The main pathogenic variations were frameshift variations (8 patients). Conclusions: IDDBCS should be considered when patients show nervous developmental abnormalities, craniofacial anomalies, seizures and overgrowth. PHF21A gene variation detection helps to make a definite diagnosis.

Objective: To summarize the clinical characteristics of epileptic seizure associated with neurofibromatosis type 1 (NF1). Methods: From January 2017 to July 2023 at Children's Hospital Capital Institute of Pediatrics, medical records of patients with both NF1 and epileptic seizure were reviewed in this case series study. The clinical characteristics, treatment and prognosis were analyzed retrospectively. Results: A total of 15 patients(12 boys and 3 girls) were collected. Café-au-lait macules were observed in all 15 patients. There were 6 patients with neurodevelopmental disorders and the main manifestations were intellectual disability or developmental delay. The age at the first epileptic seizure was 2.5 (1.2, 5.5) years. There were various seizure types, including generalized tonic-clonic seizures in 8 patients, focal motor seizures in 6 patients, epileptic spasm in 4 patients, tonic seizures in 1 patient, absence in 1 patient, generalized myoclonic seizure in 1 patient and focal to bilateral tonic-clonic seizure in 1 patient. Among 14 patients whose brain magnetic resonance imaging results were available, there were abnormal signals in corpus callosum, basal ganglia, thalamus or cerebellum in 6 patients, dilated ventricles of different degrees in 3 patients, blurred gray and white matter boundary in 2 patients, agenesis of corpus callosum in 1 patient and no obvious abnormalities in the other patients. Among 13 epilepsy patients, 8 were seizure-free with 1 or 2 antiseizure medications(ASM), 1 with drug resistant epilepsy was seizure-free after left temporal lobectomy, and the other 4 patients who have received 2 to 9 ASM had persistent seizures. One patient with complex febrile convulsion achieved seizure freedom after oral administration of diazepam on demand. One patient had only 1 unprovoked epileptic seizure and did not have another seizure without taking any ASM. Conclusions: The first epileptic seizure in NF1 patients usually occurs in infancy and early childhood, with the main seizure type of generalized tonic-clonic seizure and focal motor seizure. Some patients have intellectual disability or developmental delay. Most epilepsy patients achieve seizure freedom with ASM.

Objective:To build a performance appraisal system for full-time researchers in specialized children′s hospitals, so as to mobilize their enthusiasm and improve their efficiency of scientific and technological output.Methods:Based on structure-process-result model, the library of indexes was initialized by such means as literature review and talent performance appraisal management experiences. From November 2020 to March 2021, Delphi method was adopted to finalize the appraisal indexes and weight of each index, while the quantifiable standards of the indexes were formulated by brainstorming, hence establishing the performance appraisal model index system for these researchers. Using both the new model and the original performance appraisal system of the hospital respectively, five full-time research staffs of research-oriented children′s hospital were selected for an empirical research on performance appraisal.Results:Fifteen experts carried out two rounds of Delphi research, finalizing a performance appraisal model for these researchers. The model comprises 3 level-1 indexes, 8 level-2 indexes and 23 level-3 indexes. Among them, the weight of scientific research output, scientific research process and scientific research investment of level-1 indexes were 0.507, 0.267 and 0.226, respectively. Empirical research showed that compared with the original appraisal indexes, the results of the new performance appraisal model were more targeted, enabling the research team to identify setbacks.Conclusions:The indexes set in the model built in this study prove more scientific, objective, and more reasonable in weight assignment. Such indexes can positively motivate and encourage the researchers, promoting the clinical-basic research integration, as well as the disciplinary development and research talent cultivation of the hospital.

ObjectiveTo explore the differences in response to bakuchiol-induced hepatotoxicity between Institute of Cancer Research （ICR） mice and Kunming （KM） mice. MethodThe objective manifestations of bakuchiol-induced hepatotoxicity in mice were confirmed by acute and subacute toxicity animal experiments， and enrichment pathways of differential genes between normal ICR mice and KM mice were compared by transcriptomics. The real-time quantitative polymerase chain reaction （real-time qPCR） assay was used to verify the mRNA expression of key genes in the related pathways to confirm the species differences of bakuchiol-induced liver injury. ResultIn the subacute toxicity experiment， compared with the normal mice， the ICR mice showed increased serum content of alkaline phosphatase （ALP）， and 5′-nucleotidase （5′-NT）， without significant difference， and no manifest change was observed in KM mice. Pathological results showed that hepatocyte hypertrophy was the main pathological feature in ICR mice and hepatocyte steatosis in KM mice. In the acute toxicity experiment， KM mice showed erect hair， mental malaise， and near-death 3 days after administration. The levels of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in KM mice （400 mg·kg^-1） significantly increased（P<0.01）， and the activity of total reactive oxygen species （SOD） in liver significantly decreased（P<0.01）compared with those in normal mice， while the serum content of 5′-NT and cholinesterase （CHE） in ICR mice （400 mg·kg^-1） were significantly elevated （P<0.01）. The liver/brain ratio in ICR mice increased by 20.34% and that in KM mice increased by 29.14% （P<0.01）. The main pathological manifestation of the liver in ICR mice was hepatocyte hypertrophy， while those in KM mice were focal inflammation， hepatocyte hypertrophy， and hepatocyte steatosis. Kyoto Encyclopedia of Genes and Genomes（KEGG）and Reactome pathway enrichment analyses showed that the differential gene expression between ICR mice and KM mice was mainly involved in oxidative phosphorylation， bile secretion， bile acid and bile salts synthesis， and metabolism pathway. CYP7A1 was up-regulated in all groups with drug intervention （P<0.01） and MRP2 was reduced in all groups with drug intervention of KM mice （P<0.01） and elevated in all groups with drug intervention of ICR mice （P<0.01） compared with those in the normal group. The expression of BSEP was lowered in ICR mice with acute liver injury （400 mg·kg^-1） （P<0.05）. SHP1 was highly expressed in KM mice with acute liver injury （400 mg·kg^-1）. The expression of FXR was diminished in ICR mice with subacute liver injury （200 mg·kg^-1） （P<0.01）. SOD1， CAT， and NFR2 significantly decreased in KM mice with acute liver injury （400 mg·kg^-1）， and CAT dwindled in KM mice with subacute liver injury （200 mg·kg^-1） （P<0.01）. GSTA1 and GPX1 significantly increased in KM mice with acute liver injury （400 mg·kg^-1） （P<0.01） and SOD1， CAT， NRF2， and GSTA1 significantly increased in ICR mice with subacute liver injury （200 mg·kg^-1） （P<0.01）. CAT and NRF2 significantly increased in ICR mice with acute liver injury （400 mg·kg^-1） （P<0.01）. ConclusionWith the increase in the dosage of bakuchiol， the liver injury induced by oxidative stress in KM mice was gradually aggravated， and ICR mice showed stronger antioxidant capacity. The comparison of responses to bakuchiol-induced hepatotoxicity between ICR mice and KM mice reveals that ICR mice are more suitable for the investigation of the mechanisms related to bile secretion and bile acid metabolism in the research on bakuchiol-induced hepatotoxicity in mice. KM mice are more prone to liver injury caused by oxidative stress.
