OBJECTIVE: To explore the genetic etiology of 46 Chinese pedigrees affected with Hereditary multiple exostoses (HME) and provide genetic counseling and reproductive intervention. METHODS: Whole-exome sequencing and Sanger sequencing were carried out on 87 patients from the 46 pedigrees to analyze the variants of EXT1 and EXT2 genes. Pathogenicity of the variants was assessed based on the guidelines from the American College of Medical Genetics and Genomics and Association for Molecular Pathology (ACMG/AMP). Prenatal diagnosis and preimplantation genetic testing (PGT) were provided for couples with identified pathogenic mutations. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: LL-SC-SG-2014-010). RESULTS: In total 17 and 22 pathogenic variants were respectively identified in the EXT1 and EXT2 genes, among which 5 EXT1 and 12 EXT2 variants were unreported previously. Three patients with no family history were found to harbor de novo variants of the EXT1 gene. Twenty nine couples had opted for PGT or underwent prenatal diagnosis following natural conception, and 17 healthy babies were born. CONCLUSION This study has clarified the genetic etiology of 45 HME pedigrees and identified 17 novel variants, which has enriched the mutational spectrum of the EXT1 and EXT2 genes. Reproductive intervention through PGT and prenatal diagnosis have prevented the recurrence of HME in these families.

Skeletal muscle atrophy is characterized by a reduction in both the size and quantity of skeletal muscle fibers, resulting in impaired muscle strength and function. It mainly includes disuse muscle atrophy, aging muscle atrophy, denervated muscle atrophy and muscle atrophy caused by disease etc. As a cost-effective way, exercise has been widely used in the prevention and treatment of skeletal muscle atrophy, but its mechanism for improving skeletal muscle atrophy remains unclear. Recent studies have indicated that insulin-like growth factor 1 (IGF-1) plays an important role in improving muscle atrophy through exercise, in addition to promoting the survival of neurons, lowering blood sugar, and anti-inflammation. This article reviews recent findings on the mechanisms by which IGF-1 mediates exercise-induced improvement in skeletal muscle atrophy, providing a theoretical basis for the prevention and treatment of this disease.

OBJECTIVES: To investigate the expression of soluble factor-related apoptosis ligand (sFasL) in peripheral blood and microRNA-147b (miR-147b) in monocytes in children with sepsis and their value in assessing prognosis. METHODS: A prospective study was conducted on 124 children with sepsis (sepsis group), 60 children with common infections (infection group), and 60 healthy children undergoing physical examinations (healthy control group). The independent risk factors for poor prognosis in children with sepsis were analyzed, and the value of serum sFasL and monocyte miR-147b in predicting poor prognosis in children with sepsis was assessed. RESULTS: The serum level of sFasL and the relative expression of miR-147b in monocytes were highest in the sepsis group, followed by the infection group and the healthy control group (P<0.05). The multivariate logistic regression analysis showed that the serum level of sFasL and the relative expression of miR-147b in monocytes were closely associated with the poor prognosis of children with sepsis (P<0.05). The receiver operating characteristic curve analysis showed that the combination of serum sFasL level and relative expression of miR-147b in monocytes had a larger area under the curve compared to each indicator alone in predicting the prognosis of children with sepsis (P<0.05). CONCLUSIONS There are significant increases in the level of sFasL in peripheral blood and the relative expression of miR-147b in monocytes in children with sepsis. The combined use of these two indicators has relatively high clinical value in assessing the prognosis of children with sepsis.

Chronic cerebral hypoperfusion leads to white matter injury (WMI), which plays a significant role in contributing to vascular cognitive impairment. While 13-docosenamide is a type of fatty acid amide, it remains unclear whether it has therapeutic effects on chronic cerebral hypoperfusion. In this study, we conducted bilateral common carotid artery stenosis (BCAS) surgery to simulate chronic cerebral hypoperfusion-induced WMI and cognitive impairment. Our findings showed that 13-docosenamide alleviates WMI and cognitive impairment in BCAS mice. Mechanistically, 13-docosenamide specifically binds to cannabinoid receptor 1 (CNR1) in oligodendrocyte precursor cells (OPCs). This interaction results in an upregulation of ubiquitin-specific peptidase 33 (USP33)-mediated CNR1 deubiquitination, subsequently increasing CNR1 protein expression, activating the phosphorylation of the AKT/mTOR pathway, and promoting the differentiation of OPCs. In conclusion, our study suggests that 13-docosenamide can ameliorate chronic cerebral hypoperfusion-induced WMI and cognitive impairment by enhancing OPC differentiation and could serve as a potential therapeutic drug.

AIM: To investigate the mechanism of Hexue Mingmu Tablets(HXMMT)in improving diabetic retinopathy(DR)based on transcriptomics.METHODS: Zebrafish DR models were established by 3-day glucose induction(130 mmol/L)starting at 3 days post-fertilization(dpf). Larvae were randomized into four groups: control group(CG; aquaculture water), model group(MG; 130 mmol/L glucose), low-dose HXMMT treatment group(L-HX; 130 mmol/L glucose +7.5 mg/L HXMMT), and high-dose HXMMT treatment group(H-HX; 130 mmol/L glucose +75 mg/L HXMMT), with a 3-day intervention period until 6 dpf. The area and length of eyes, and body length of zebrafish were observed by stereomicroscopy, retinal morphology was observed by hematoxylin-eosin staining(HE), and retinal vessel diameter was observed under fluorescence microscope. Differentially expressed genes(DEGs)were identified by RNA-sequencing(RNA-seq)technology to further elucidate the molecular mechanism of HXMMT in improving DR in zebrafish, and the sequencing accuracy was validated through quantitative real-time polymerase chain reaction(qRT-PCR).RESULTS: HE staining demonstrated that the intervention with HXMMT significantly improved the disordered cell arrangement, widened gaps, and thickened inner nuclear layer(INL)in ganglion cell layer GCL); retinal vascular diameter quantification revealed that the retinal vessel diameter of the MG significantly increased compared with the CG, and it was significantly changed after the intervention of HXMMT, with significant efficacy in the H-HX(P<0.05); transcriptomics profiling identified 1 470 reversed DEGs, predominantly enriched in the AMPK signaling pathway, FoxO signaling pathway, retinal developmental processes, and tight junction regulation. Technical validation confirmed strong correlation between qRT-PCR and RNA-seq data(R2=0.8571, P<0.05).CONCLUSION: HXMMT may improve retinal vascular microcirculation disorders in DR by regulating core targets including vsx1, pde6c, arr3a, plk1, fbp1b, foxo1a, pcna, and cdk1, as well as synergistically modulating processes such as retinal development in camera-type eyes, visual perception, microtubule cytoskeletal organization, tight junctions, and the AMPK signaling pathway, Foxo signaling pathway.
