RESUMEN
BACKGROUND AND AIMS: As a gut microbiota-dependent metabolite, trimethylamine N-oxide (TMAO) has been implicated in cardiovascular diseases. We aimed to investigate the relationship between the clinical outcomes and plasma TMAO concentrations in patients with acute intracerebral hemorrhage. METHODS: From January 2019 to October 2019, we prospectively enrolled intracerebral hemorrhage patients diagnosed within 6 h of symptoms onset. Plasma TMAO levels was measured for all patients within 24 h after admission. The primary outcome was functional outcome at 3 months. Patients were dichotomized as good (modified Rankin scale 0-3) and poor (modified Rankin scale 4-6). Secondary outcome included early neurological deterioration (END) and hematoma enlargement (HE). RESULTS: There were 307 patients (57.7% male) with a mean age of 66.8 years included in the study. The median TMAO levels was 3.2 µmol/L. END, HE, and 3-month poor outcome were detected in 59 (19.2%), 54 (17.6%), and 139 (45.3%) patients, respectively. After adjusting for potential confounders, the odds ratio for the highest quartile of TMAO compared with the lowest quartile was 3.65 (95% confidence interval, 1.43-9.30) for 3-month poor outcome. Furthermore, multiple-adjusted spline regression model showed a linear association between TMAO levels and poor outcome at 3 months (P = 0.013 for linearity). Similar significant findings were observed when functional outcome was analyzed by continuous mRS score. No association was found between TMAO levels and END and HE. CONCLUSIONS: The present study demonstrated that increased TMAO levels were independently correlated with 3-month function outcome after intracerebral hemorrhage.

Hemorrhagic transformation (HT) is one of the most dangerous complications after intravenous thrombolysis in patients with acute ischemic stroke (AIS). Therefore, we want to explore the predictive effects of peripheral blood S100ß and C-Reactive Protein (CRP) levels on hemorrhagic transformation after intravenous thrombolysis in AIS patients. Ninety-two AIS patients who had been treated in Huai'an Second People's Hospital from January 2018 to December 2021 were retrospectively selected. Patients were divided into hemorrhagic transformation (HT) groups (24 cases) and no HT groups (68 cases) based on whether there was hemorrhagic transformation within 24 h after intravenous thrombolysis. General clinical data from the HT group and no HT group were compared. A multivariate logistic regression model was used to analyze the potential risk factors of HT after intravenous thrombolysis in patients with AIS. A receiver operating curve (ROC) was used to analyze the predictive value of risk factors for HT. High serum S100ß, CRP levels, and National Institutes of Health Stroke Scale (NIHSS) scores were found to be risk factors for HT after intravenous thrombolysis in patients with AIS (all P < .05). The ROC curve analysis showed that critical value of S100ß, CRP level, and NIHSS score for predicting intravenous thrombolytic HT in AIS patients were 0.335, 8.700, and 14.50, respectively, and their sensitivities were 0.750, 0.971, and 0.333 ( P < .05), respectively. High serum S100ß and CRP levels are risk factors for HT after intravenous thrombolysis in AIS patients and have predictive influence of the occurrence of HT in AIS patients.

Purpose: To explore the relationship between the serum level of S100 calcium-binding protein, beta chain (S100ß) and Parkinson's disease (PD) with depression. Patients and Methods: A total of 145 patients with PD and 60 healthy controls matched for sex, age, and years of education in our hospital were selected. Fluorescence quantitative immunochromatography was used to quantify the level of S100ß in serum. Clinical manifestations were assessed by Unified Parkinson's Disease Rating Scale part-III (UPDRS-III), Hoehn & Yahr (H-Y) stage and 17-item Hamilton Rating Scale for Depression (HAMD-17). According to the results of HAMD-17, PD patients were divided into PD with depression group and PD without depression group. The relationship between serum S100ß and HAMD-17 scores in PD patients with depression was investigated through correlation analysis and multivariate regression analysis, and receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of serum S100ß. Results: The level of serum S100ß in PD with depression group was significantly higher than that in PD without depression group and control group. In PD patients with depression, serum S100ß level was positively correlated with UPDRS-III score, H-Y Scale and HAMD-17 score. The HAMD-17 score was positively correlated with the UPDRS-III and H-Y scales, and the increase in the HAMD-17 score was associated with women. Elevated serum S100ß level and UPDRS-III score are independent risk factors for PD with depression. Analysis of receiver operating characteristic (ROC) curves showed that the serum S100ß level with a cutoff of 0.28 ng/mL distinguished patients with PD with or without depression with an area under the ROC curve (AUC) of 0.742, sensitivity of 0.696, and specificity of 0.779. Conclusion: The serum S100ß level could be a biomarker of PD with depression.
RESUMEN
PURPOSE: To explore the correlation between Atherogenic Index of Plasma (AIP) and early neurological deterioration (END) in patients with acute ischemic stroke (AIS). METHODS: A retrospective analysis of 334 patients diagnosed with AIS between January 2021 and May 2023 at the Affiliated Huai'an Hospital of Xuzhou Medical University. Patients were divided into END and non-END groups based on changes in National Institutes of Health Stroke Scale scores (NIHSS) within 7 days of admission, and the differences in the indicators between the two groups were examined using univariate analysis. The patients were then divided into three groups based on the tertile of the AIP (T1: AIP≤ -0.01; T2: 0 ≤AIP≤0.16; AIP≥0.17), and logistic regression analysis was used to examine the association between the AIP and END. Finally, the predictive ability of the AIP was evaluated using the receiver operating characteristic (ROC) curve. RESULTS: A total of 334 patients were included, of which 64 (19.20%) had END. The results of the analysis showed that the AIP was significantly higher in the END group compared to the non-END group. Multivariable logistic regression analysis showed that higher AIP was associated with END in AIS patients (OR=3.259, 95%CI, 1.490-7.125, P = 0.003), especially in large-artery atherosclerosis (LAA) subtype (OR=4.240, 95%CI,1.30-13.87, P = 0.017). ROC analysis revealed that the best predictive cutoff value of AIP was 0.115, and the area under the ROC curves for AIP was 0.681(0.604-0.758). CONCLUSION: Our study uncovered that higher AIP levels were associated with END development in AIS patients.

BACKGROUND: To: (i) explore the effect of diterpene ginkgolides meglumine injection (DGMI) on neurological deficit symptoms in acute atherosclerotic cerebral infarction (AACI) patients; (ii) measure the level of plasma plasminogen activator inhibitor (PAI)-1 and tissue plasminogen activator (t-PA). METHODS: Eighty AACI patients were divided equally and randomly into the DGMI group and control group. In addition to basic treatment, the DGMI group was treated with DGMI (25 mg/d) for 14 days. The control group had basic treatment without DGMI. Before and after treatment, the degree of neurological deficit was assessed, thromboelastography undertaken, and plasma levels of PAI-1 and t-PA measured. RESULTS: The National Institutes of Health Stroke Scale score of patients in the DGMI group after treatment was lower than that in the control group, and the Barthel Index was higher than that in the control group ( P <0.05). Thromboelastography revealed that, in the DGMI group, the R value and K value after treatment were higher than before treatment, the angle and maximum amplitude value were lower than before treatment, and both were significant ( P <0.05). Compared with the control group, the plasma PAI-1 level of patients in the DGMI group was lower than that in the control group, and the t-PA level was higher than that in the control group ( P <0.05) after 14 days of treatment. CONCLUSIONS: DGMI may affect the activity of the blood coagulation and fibrinolysis system by regulating the plasma level of PAI-1 and t-PA, and improving neurological deficit symptoms. DGMI is important for improving the prognosis of patients with AACI.

OBJECTIVE: To retrospectively investigate the relationship between apolipoprotein E (APOE) gene polymorphism and in-stent restenosis (ISR) after stenting at the beginning of the vertebral artery. METHODS: The study included 155 patients who successfully underwent stenting at the beginning of the vertebral artery and had postoperative digital subtraction angiography or computed tomography angiography. Based on the follow-up results, they were divided into the restenosis (ISR) group and non-restenosis (non-ISR) group. The clinical information and APOE genotypes of both groups were analyzed. A binary logistic regression model was used to analyze independent risk factors for ISR. RESULTS: After 1 year of follow-up, 49 (31.6%) patients had ISR and 106 (68.4%) did not. Binary logistic regression analysis showed that serum low-density lipoprotein cholesterol (LDL-C), serum lipoprotein-related phospholipase A2 (Lp-PLA2), and E3/E4 genotype were independent risk factors for ISR after stenting at the beginning of the vertebral artery. In addition, the LDL-C level of patients with the E3/E4 genotype was higher compared with the E3/E3 genotype group (P < 0.05). CONCLUSIONS: APOE gene polymorphism is associated with ISR, and the E3/E4 genotype is an independent risk factor for ISR after stenting at the beginning of the vertebral artery. Further genetic studies can identify risk genotypes to facilitate the early prediction and identification of high-risk patients with ISR.

INTRODUCTION: To investigate the function of miR-190a-3p on the proliferation and migration of glioma. METHODS: Twenty glioma samples and 6 normal brain tissue samples were collected. Normal human glial cell line HEB and glioma cell lines were used for the experiments. We then used TargetScan to predict the target genes of miR-190a-3p. Dual-luciferase reporter assay was also used to validate. RESULTS: Combined with dual-luciferase reporter experiment, we finally verified that YOD1 was the aim, and it was low-expressed in glioma. Besides, a series of mechanism experiments then proved that miR-190a-3p negatively regulates YOD1 expression. CONCLUSIONS: Our research was the first to demonstrate the promoting function of miR-190a-3p in the proliferation and migration of glioma and provided new views for the treatment of glioma. miR-190a-3p was expected to be a new target for molecular therapy of glioma.

BACKGROUND: Alzheimer's disease (AD), a leading cause of dementia, becomes a serious health issue for individuals and society around the world. AD is a neurodegenerative disease characterized by the deposition of amyloid-ß (Aß) peptides and neurofibrillary tangles (NFT) and the loss of large numbers of neurons. To date, there is no effective treatment for AD, and thus, to enhance neurogenesis in the AD brain may be a therapeutic strategy. RAS signaling pathway involves in synaptic plasticity and memory formation, which is overexpressed in brains with AD. This study used Aß1-42-injected mice (Aß1-42-mice) as the AD model to investigate the effects of S-trans, trans-farnesylthiosalicylic acid (FTS), a synthetic Ras inhibitor, on the impairment of neurogenesis and the spatial cognitive deï¬cits. MATERIALS AND METHODS: AD model mice were manufactured through intracerebroventricular injection of Aß1-42. Morris water maze (MWM) was performed to evaluate the capacity of spatial memory, and Nissl staining was applied to assess neuronal damage in the hippocampus CA1. Immunohistochemistry of 5-bromo-2-deoxyuridine (BrdU), BrdU/neuronal nuclei (NeuN), and doublecortin (DCX) were used to detect progenitor cell proliferation, maturation, and neurite growth, respectively. And the expression levels of RAS, ERK/ERK phosphorylation (p-ERK) and CREB/CREB phosphorylation (p-CREB) were detected by Western blot. RESULTS: The results demonstrated that FTS could prevent Aß1-42 to impair survival and neurite growth of newborn neurons in the hippocampal dentate gyrus (DG) in Aß1-42-mice. Furthermore, behavioral indexes and morphological findings showed that FTS improved the learning and spatial memory abilities of Aß1-42-mice. In addition, FTS could inhibit the levels of hippocampal p-ERK and p-CREB activated by Aß, which is the underlying molecular mechanism. CONCLUSION: In conclusion, these findings suggest that FTS as a RAS inhibitor could be a potential therapeutic agent for the treatment of AD.
