Spinal cord injury (SCI) is a debilitating condition of the central nervous system (CNS) that leads to severe impairments in sensory and motor functions. Previous studies have pointed out that patient age is a critical factor influencing SCI prognosis. However, the role of microglia in age-related differences in SCI outcomes remains unclear.

However, caution is advised for patients with only one functioning eye or high visual expectations.
Objective: To assess the efficacy and safety of phaco-GSL in patients with end-stage PACG exhibiting tubular vision or temporal field island.
Background: The overall survival (OS) rate of adult patients suffering from acute myeloid leukaemia (AML) remains unsatisfactory at less than 40%. Current risk stratification systems fail to provide accurate guidelines for precise treatment. Novel biomarkers for predicting prognosis are urgently needed.

Low overall survival of AML is due to non-remission or relapse after remission. Hypomethylating agent (HMA) decitabine combined with low-dose chemotherapy or other targeted agents has shown promising effect for AML in clinical trials, especially in (8;21) acute myeloid leukemia.

Purpose: This study was conducted in order to test the expression of vasoactive substances within rat lamina cribrosa (LC) and optic nerve head (ONH) astrocytes, so as to investigate the role and potential mechanism of ONH astrocytes in vascular associated effects.
Methods: LC tissue sections and primary cultured ONH astrocytes were obtained from adult Sprague-Dawley (SD) rats. Immunofluorescent staining was then used to detect the expression of vasoactive substances.
Hepatocellular carcinoma is a disastrous cancer with an aberrant metabolism. In this study, we aimed to assess the role of metabolism in the prognosis of hepatocellular carcinoma. Ten metabolism-related pathways were identified to classify the hepatocellular carcinoma into two clusters: Metabolism_H and Metabolism_L.

Hepatic stellate cells (HSCs) activation play a central role in liver fibrosis, and persistently damaged hepatocytes secrete soluble factors that activate transdifferentiation of HSCs into myofibroblasts. Our previous studies indicated that fine particulate matter (PM2.

Based on unsupervised clustering and the expression levels of ferroptosis genes, patients with cancer were divided into two clusters. The least absolute shrinkage and selection operator method Cox regression analysis was used to establish the survival-predictor model.

The interaction between various types of hepatic cells is related to liver fibrosis. Recent studies demonstrated that fine particulate matter (PM2.5) exposure is an important risk factor for the occurrence of liver fibrosis, but its molecular mechanism is still obscure.

Circular RNAs (circRNAs) regulate biological and pathogenic processes, suggesting a potential role in AML. We have previously described the overall alterations in circRNAs and their regulatory networks between patients with AML presenting with and without EMI.
View Article and Find Full Text PDFOur previous studies revealed that MYCN downregulates the expression of DKK3, activates the Wnt/β-catenin signalling pathway at the transcriptional level, and thereby promotes the development of B cell acute lymphocytic leukaemia (B-ALL) but does not affect the methylation of the DKK3 promoter. Some studies have shown that MYCN is associated with histone acetylation. We speculate that histone deacetylase inhibitors (HDACis) can inhibit the Wnt/β-catenin signalling pathway by inhibiting MYCN and increasing the expression of DKK3.

We established a model of adjacent intervertebral disc degeneration after spinal fixation and fusion of rabbits maintained in upright feeding cages. Twenty-five healthy New Zealand rabbits were used.

Five patients with corneal, iris, and retinal neovascularization and no light perception were treated with intravitreal injections of artesunate 80 μg. Visual acuity, anterior segment photography, fundus fluorescein angiography, and optical coherence tomography were used to evaluate efficacy, while intraocular pressure (IOP) and lens opacity degree were employed to evaluate safety.

Circular RNAs (circRNAs) are a novel class of non-coding RNAs that feature covalently closed continuous loops, suggesting their potential as micro RNA (miRNA) "sponges" that can participate in biological processes and pathogenesis. However, investigations on circRNAs in EMI were conducted rarely.

Our previous studies have shown that miR-708 down-regulates DKK3 at the post-transcriptional level in B-ALL. However, whether transcriptional mechanisms lead to DKK3 silencing remains unclear.

Methods: Six months after diabetes induction, the retinal vessels of male C57BL/6 J mice were observed by colour photography, fundus fluorescein angiography (FFA), and immunofluorescent staining following incubation with CD31. Immunofluorescence for glial fibrillary acidic protein (GFAP), alpha-smooth muscle actin (α-SMA),and NG2 was also performed.
Inactivation of Dickkopf-3 (DKK3) is closely associated with a poor prognosis in various solid tumor and hematologic malignancies. Promoter hypermethylation is one potential cause of DKK3 inactivation. However, whether other mechanisms lead to DKK3 inactivation and the subsequent effects of these inactivations on cell proliferation and the Wnt signaling pathway in adult B acute lymphoblastic leukemia (B-ALL) remain unclear.

Methods: In total, 99 Type 2 DM patients were recruited for the study and were divided into three groups: DM with non-obvious retinopathy (DM, n = 29), non-proliferative diabetic retinopathy (NPDR, n = 40), and proliferative diabetic retinopathy (PDR, n = 30). In addition, 78 age-matched healthy individuals were chosen as the control.
Aim: To explore how oxygen saturation in retinal blood vessels is altered in ischemic and non-ischemic branch retinal vein occlusion (BRVO).
Methods: Fifty BRVO eyes were divided into ischemic (n=26) and non-ischemic (n=24) groups, based on fundus fluorescein angiography. Healthy individuals (n=52 and n=48, respectively) were also recruited as controls for the two groups.

Purpose: To investigate changes in retinal vessel oxygen saturation and diameter in high myopia.
Methods: Relative oxygen saturation was measured in the retinal blood vessels of 54 participants with high myopia and compared to a control group of 54 individuals with emmetropia with the Oxymap T1 retinal oximeter. The participants with high myopia were further divided into two groups according to the grade of myopic retinopathy: Group A (grade < M2 ) and Group B (grade ≥ M2 ).
