RESUMO
Abstract@#Myopia has become a major public health issue of global concern. Scientific and effective myopia prediction models can help identify high risk groups for myopia, thereby achieving precise prevention. With the rapid development of genome wide association studies and the establishment of large scale prospective population cohorts, the polygenic risk score (PRS) model has been used to predict myopia phenotypes, advancing the myopia prediction window and thus predicting high myopia risk for early screening and intervention for at risk groups. The review aims to systematically elaborate the identification and verification of myopia genes in recent years, briefly describe the practice and effectiveness evaluation of the PRS model in myopia prevention research at home and abroad, reveal the application value in myopia prediction research, and emphasize the relationship between the PRS prediction model and outdoor activities. Close eye use and other preventive measures are of great significance to promote the precise prevention of myopia in children and adolescents.
RESUMO
BACKGROUND: Dandy-Walker malformation (DWM) was first reported in 1914. In this case report, a pediatric case was complicated with giant and isolated arachnoid cysts in the right cerebellar hemisphere along with the typical DWM. CASE SUMMARY: The patient was at 20 mo old boy, with the complaint of staggering for more than 2 mo. He was admitted to the hospital due to high intracranial pressure and staggering. At admission, the patient had typical manifestations of high intracranial pressure, including vomiting, poor appetite and feeding difficulty. Physical examination revealed increased head circumference, closed anterior fontanelle, unstable standing, staggering, leaning right while walking and ataxia. After admission, he was diagnosed with DWM accompanied by giant isolated arachnoid cysts in the posterior fossa. He underwent Y-shaped three-way valve repair for treating differential pressure between the supratentorial hydrocephalus and the subtentorial arachnoid cysts at once. The child recovered well after the surgery. CONCLUSION: In this case, supratentorial and subtentorial shunts were placed, which solved the problem of differential pressure between the supratentorial and subtentorial parts simultaneously. This provides useful information regarding treatment exploration in this rare disease.
RESUMO
Accumulating studies revealed association between development of glioma and miRNA dysregulation. A case in point is miR-381-3p, but its mechanism in glioma is unclear yet. In this work, we confirmed that overexpressed miR-381-3p repressed biological functions of glioma cells. Additionally, we also discovered that upregulated anthrax toxin receptor 1 (ANTXR1) was negatively mediated by miR-381-3p. We further proved that miR-381-3p-targeted ANTXR1 was able to counteract the suppression of miR-381-3p on biological functions of glioma. We concluded that miR-381-3p and ANTXR1 were both important factors in modulating glioma progression. miR-381-3p/ANTXR1 axis is expected to be a molecular target for glioma.
