Background And Aims: Newborn screening (NBS) for glucose-6-phosphate dehydrogenase (G6PD) deficiency by biochemical tests is being used worldwide, however, the outcomes arising from combined genetic and biochemical tests have not been evaluated. This research aimed to evaluate the outcomes of application of combined genetic and biochemical NBS for G6PD deficiency and to investigate the molecular epidemiological characteristics, variant spectrum, and genotype-phenotype correlation of G6PD deficiency in China.

Methods: A population-based cohort of 29,601 newborns were prospectively recruited from eight NBS centers in China between February 21 and December 30, 2021.

Article Synopsis
  • - The study investigated the relationship between genetic factors and the phenotype of retinal hemangioblastomas (RH) in a Chinese group of 51 individuals, using advanced genetic testing methods to identify mutations in the Von Hippel-Lindau (VHL) gene.
  • - Out of the participants, 36 were diagnosed with VHL syndrome, showing a younger median age of onset, while 15 were excluded from this diagnosis; four novel genetic variants were found, alongside established mutation hotspots.
  • - The classification of RH types showed a predominance of extrapapillary lesions in the peripheral retina, and high frequencies of both major genomic deletions and CNS hemangioblastomas in affected families suggest that RH may be an early warning sign for

High mobility group box 1 (HMGB1) is a highly conserved and ubiquitous nuclear protein in eukaryotic cells. In response to stress, it transfers from the nucleus to the cytoplasm and finally, to the extracellular matrix, participating in inflammation and carcinogenesis. Increased HMGB1 protein levels are frequently associated with the reduced survival of patients with glioma.

In today's data-driven digital culture, there is a critical demand for optimized solutions that essentially reduce operating expenses while attempting to increase productivity. The amount of memory and processing time that can be used to process enormous volumes of data are subject to a number of limitations. This would undoubtedly be more of a problem if a dataset contained redundant and uninteresting information.

Marine sediments in coastal zones serve as valuable archives for understanding the history of silicate chemical weathering and summer monsoon rainfall in source areas, providing insights into terrigenous climate and environmental evolution. In this study, we investigated the grain size, clay minerals, and geochemistry of sediments retrieved from core KZK01 in the coastal zone of the northwest South China Sea during the past 13 thousand years before present (kyr BP). Our findings demonstrated that the illite crystallinity index served as a reliable proxy for assessing the intensity of chemical weathering in the source area.

p58 is a multifaceted endoplasmic reticulum (ER) chaperone and a regulator of eIF2α kinases involved in a wide range of cellular processes including protein synthesis, ER stress response, and macrophage-mediated inflammation. Systemic deletion of p58 leads to age-related loss of retinal ganglion cells (RGC) and exacerbates RGC damage induced by ischemia/reperfusion and increased intraocular pressure (IOP), suggesting a protective role of p58 in the retina. However, the mechanisms remain elusive.

Article Synopsis
  • The study aimed to identify risk factors for repeated retinal detachment after surgical treatment in Chinese patients with rhegmatogenous retinal detachment and choroidal detachment (RRD-CD).
  • Researchers reviewed data from 1212 patients, finding a recurrence rate of 21.3%, with higher rates among males, middle-aged individuals, and those with specific preoperative characteristics.
  • Factors such as gender, age, preoperative vision, axial length, and usage of scleral buckling were identified as potential risks for recurrence occurring typically about three months post-surgery.

Accumulating evidence suggests that inflammation is present in solid tumors. However, it is poorly understood whether inflammation exists in glioma and how it affects the metabolic signature of glioma. By analyzing immunohistochemical data and gene expression data downloaded from bioinformatic datasets, the present study revealed an accumulation of inflammatory cells in glioma, activation of microglia, upregulation of proinflammatory factors (including IL‑6, IL‑8, hypoxia‑inducible factor‑1α, STAT3, NF‑κB1 and NF‑κB2), destruction of mitochondrial structure and altered expression levels of electron transfer chain complexes and metabolic enzymes.

Objective: Corneal disease is one of the main causes of blindness for humans globally nowadays, and deep anterior lamellar keratoplasty (DALK) is a widely applied technique for corneal transplantation. However, the position of stitch points highly influences the success rate of such surgery, which would require accurate control and manipulation of surgical instruments.

Methods: In this paper, we present a deep learning framework for augmented reality (AR) based surgery navigation to guide the suturing in DALK.

High mobility group box 1 (HMGB1) is an abundant non-histone nuclear protein that functions as a structural protein of chromatin, regulating genome replication and recombination, mRNA transcription and DNA repair. HMGB1 has been implicated in the tumorigenesis of various cancer types, and the upregulation of HMGB1 has been demonstrated in glioma cells. However, the association between HMGB1 and the mitotic chromosomes in glioma remains uncharacterized.

We aimed to characterize the role of HMGB1 overexpression in glioma and to evaluate its use as a biomarker. We used the gene expression datasets and tissue microarray to assess the expression levels of HMGB1 among gliomas of all grades; We then assessed its correlation with the malignancy and outcome of glioma. The increase in HMGB1 mRNA and protein levels was found in glioma, but there was no correlation between HMGB1 expression and glioma malignancy, and overall survival and vital status of glioma patients.

Increasing evidence has indicated the important roles of long noncoding RNAs (lncRNAs) in human osteosarcoma tumorigenesis. In present study, we aim to investigate the roles of lncRNA SNHG20 (small nucleolar RNA host gene 20) in osteosarcoma tumorigenesis and explore the in-depth molecular mechanism. Results showed that lncRNA SNHG20 expression was up-regulated in osteosarcoma samples and its high-expression indicated the poor prognosis.
