Objective:To observe the effects of sorafenib on the lesions and vascular growth factors in the mouse model of hepatic alveolar echinococcosis.Methods:One hundred healthy female Kunming mice weighing (20±4) g were used to establish a model of alveolar echinococcosis infection by intraperitoneal injection of alveolar echinococcosis protoscoleces. After 6 weeks of feeding, the rats were divided into 5 groups, 15 rats in each group, which were given warm saline, albendazole (100 mg/kg), and sorafenib at high-dose (100 mg/kg), middle-dose (50 mg/kg) and low-dose (30 mg/kg) by gavage for 6 weeks, respectively. Eyeball blood and hepatic alveolar echinococcosis tissue were collected from the mice after the last administration, and the body weight of the mice and the lesion weight were weighed. The concentrations and expression levels of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor-A (VEGF-A) and vascular endothelial growth factor receptor-2 (VEGFR-2) in serum and lesion tissues were detected by enzyme-linked immunosorbent assay (ELISA) and Western blotting.Results:There was no statistically significant difference in the body weight of mice among the saline group, albendazole group and low-dose, medium-dose and high-dose sorafenib groups ( F=0.43, P=0.784). The ratios of lesion weight to body weight in the above groups were (0.057±0.009), (0.031±0.005), (0.033±0.005), (0.031±0.005), and (0.031±0.005), respectively. The saline group had a higher ratio than the other four groups, and the differences were statistically significant (all P<0.05). The relative expression levels of HIF-1α, VEGF-A, VEGFR-2, CD31 and CD34 detected by Western blotting in the saline group were all higher than those in the albendazole group and the high-dose, medium-dose and low-dose sorafenib groups, and the differences were statistically significant (all P<0.05). The relative expression levels of the above proteins in the medium-dose and high-dose sorafenib groups were lower than those in the albendazole group, and the relative expression levels of the above proteins in the high-dose sorafenib group were also lower than those in the medium-dose sorafenib group, and the differences were statistically significant (all P<0.05). The concentration levels of HIF-1α, VEGF-A and VEGFR-2 in serum of mice in each group detected by ELISA were consistent with those detected by Western blotting. Conclusion:Sorafenib inhibits the proliferation of alveolar echinococcosis in mice by suppressing the expression of angiogenic factors in alveolar echinococcosis lesions.

Objective To analyze the influencing factors of chronic liver failure in patients with primary hepatic carcinoma(PHC)before intervention,and to establish and evaluate a nomogram risk prediction model.Methods A retrospective analysis was conducted by collecting general data and clinical test data within 24 hours of admission for PHC patients.Univariate analysis and Lasso regression were used for variable selection,followed by multivariate logistic regression analysis to identify independent influencing factors for CLF before PHC intervention,leading to the establishment of a nomogram risk prediction model.The model was evaluated using the Hosmer-Lemeshow test,receiver operating characteristic(ROC)curve,calibration curve,clinical decision curve,and clinical impact curve.Result A total of 353 cases of PHC patients were collected,including 153 cases in the liver failure group and 200 cases in the non-liver failure group,with a prevalence rate of 43.3％.Variables selected by Lasso regression included gastrointestinal bleeding,prothrombin time(PT),albumin(ALB),total bilirubin(TBIL),and gamma glutamyl transferase(GGT).Multivariate logistic regression analysis showed that gastrointestinal bleeding(OR=13.549,95％CI:2.899～63.322,P=0.001),PT(OR=1.599,95％CI:1.282～1.995,P＜0.001),TBIL(OR=1.016,95％CI:1.006～1.025,P=0.002),and GGT(OR=1.002,95％CI:1.000～1.003,P=0.028)were independent risk factors for chronic liver failure prior to PHC intervention,leading to the establishment of a nomogram risk prediction model.The Hosmer Lemeshow test showed that the model had a good fit(x2=6.152,P＞0.05);the area under ROC was 0.902(0.869-0.934),with a sensitivity of 80.4％and a specificity of 87.5％.The calibration curve indicated that the model predicts chronic liver failure prior to PHC intervention with good consistency.Clinical decision curve analysis and clinical impact curve analysis showed that the model has good clinical utility within a certain threshold range.Conclusion Gastrointestinal bleeding,PT ≥16.05s,TBIL≥37.80 mmol/L,and GGT≥ 99.00 U/L are independent risk factors for the occurrence of chronic liver failure before PHC intervention.The established nomogram risk prediction model has certain clinical application value in predicting the risk of chronic liver failure before PHC intervention.

Local anesthetics (LAs), such as articaine (AT), exhibit limited efficacy in inflammatory environments, which constitutes a significant limitation in their clinical application within oral medicine. In our prior research, we developed AT-17, which demonstrated effective properties in chronic inflammatory conditions and appears to function as a novel oral LA that could address this challenge. In the present study, we further elucidated the beneficial effects of AT-17 in acute inflammation, particularly in oral acute inflammation, where mitochondrial-related apoptosis played a crucial role. Our findings indicated that AT-17 effectively inhibited lipopolysaccharide (LPS)-induced nerve cell apoptosis by ameliorating mitochondrial dysfunction in vitro. This process involved the inhibition of mitochondrial reactive oxygen species (mtROS) production and the subsequent activation of the NRF2 pathway. Most notably, improvements in mitochondria-related apoptosis were key contributors to AT-17's inhibition of voltage-gated sodium channels. Additionally, AT-17 was shown to reduce mtROS production in nerve cells through the Na⁺/NCLX/ETC signaling axis. In conclusion, we have developed a novel local anesthetic that exhibits pronounced anesthetic functionality under inflammatory conditions by enhancing mitochondria-related apoptosis. This advancement holds considerable promise for future drug development and deepening our understanding of the underlying mechanisms of action.

OBJECTIVE: To explore the genetic etiology for a child presenting with motor retardation, language delay, intellectual disability, and dysmorphic features. METHODS: A child presented at Linyi People's Hospital in June 2022 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples were obtained from the child and her parents. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variant was validated by Sanger sequencing. Amniotic fluid samples were obtained from the mother's subsequent pregnancies for prenatal diagnosis. This study has been reviewed and approved by the Medical Ethics Committee of Linyi People's Hospital (Ethics No.: 2019-134). RESULTS: The proband was a 2-year-old girl showing developmental delays in motor, language, and intellectual domains, strabismus, hypertelorism, hearing impairment, obesity, and brachymesophalangy of the fifth finger. Magnetic resonance imaging revealed abnormalities of the white matter. Chromosomal microarray analysis (CMA) identified a 15q26.3 duplication (chr15:101562020_102060896 × 3) inherited from her mother. WES has uncovered a heterozygous c.1931A>G (p.Tyr644Cys) variant in the FBXO11 gene. Sanger sequencing confirmed the variant to be de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as likely pathogenic. Prenatal diagnosis revealed that the fetuses from the mother's second and third pregnancies did not harbor the same variant. CONCLUSION The c.1931A>G (p.Tyr644Cys) variant of the FBXO11 gene probably underlay the abnormal phenotype in the child. Based on its genotype and phenotype, the proband was diagnosed with Intellectual developmental disorder with dysmorphic facies and behavioral abnormalities.

OBJECTIVE: To investigate the clinical and genetic characteristics of a Chinese pedigree affected with Neurodevelopmental disorder with absent language and variable seizures (NEDALVS) due to variant of WASF1 gene, and to review the literature on NEDALVS associated with WASF1 gene variants. METHODS: A 4-year-and-8-month-old boy with NEDALVS diagnosed at Linyi People's Hospital in July 2024 due to "discovering language development delay for more than 2 years" and his family members were selected as the study subjects. Clinical data of the family members were collected. Peripheral venous blood samples were collected from family members. Whole-exome sequencing (WES) was performed, and candidate variants were verified, by Sanger sequencing. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG). Using the MUpro website, SWISS-MODEL, PyMOL, Clustal X, PolyPhen-2, and Mutation Taster software, bioinformatics analysis of protein three-dimensional structure modeling for gene mutations, cross-species conservation of mutant amino acids, and pathogenicity prediction of mutation sites. Relevant literature was retrieved from databases such as CNKI, Wanfang Data Knowledge Service Platform, and PubMed, and the clinical phenotypes and genotypes of patients with WASF1 gene mutations reported in the literature were summarized and analyzed. This study was approved by the Medical Ethics Committee of Linyi People's Hospital (Ethics No.: YX200303). RESULTS: The proband, a 4-year and 8-month-old male, mainly presented with delayed language and motor development, accompanied by autistic behaviors; the proband's younger brother was 2 years and 7 months old at the time of consultation, mainly presented with delayed language and motor development, accompanied by short stature; the proband's mother mainly presents with limited language expression and poor interpersonal interaction; the proband's maternal grandmother mainly presents with soliloquizing?behavior. The results of WES showed that the proband carried a heterozygous mutation c.214C>T (p.Arg72Cys) in the WASF1 gene, and this site has not been recorded in the database. Sanger sequencing confirmed that the proband's younger brother, mother, and maternal grandmother had harbored the same variant. Based on the guidelines from the ACMG, this variant was rated as likely pathogenic (PM2_Supporting+PP1+PP3+PP4). Through SWISS-MODEL homology modeling and PyMOL structure visualization analysis, it was further confirmed that this variant can lead to a decrease in protein stability. Amino acid sequence conservation analysis of the WASF1 protein using Clustal X software suggested that the c.214C>T (p.Arg72Cys) variant has caused replacement of a highly conserved amino acid. According to the results of PolyPhen-2 and Mutation Taster, the p.Arg72Cys variant was predicted to be a hazardous. By following the retrieval strategy set in this study, a total of 5 research articles regarding to patients with NEDALVS caused by WASF1 gene mutations were retrieved, which involved 15 patients. Combining the proband and their family members discovered in this study, there were a total of 19 NEDALVS patients. The main clinical features included: motor developmental delay (100%, 17/17), language/intellectual developmental delay (100%, 17/17), epilepsy (64.7%, 11/17), autistic behavior (76.5%, 13/17), hypotonia (70.6%, 12/17), abnormal electroencephalogram (64.7%, 11/17), and short stature (17.6%, 3/17). All 19 patients had heterozygous mutations, with 8 mutation sites. Missense mutations were the most common, accounting for 84.2% (16/19). CONCLUSION A pathogenic variant of the WASF1 gene was identified in a pedigree affected with NEDALVS. Discovery of the novel variant has, expanded the mutational spectrum of the WASF1 gene.
