Background: The relationship between abnormal renal function and serum uric acid levels in patients with acute ischemic stroke (AIS) remains insufficiently explored. Although uric acid is associated with cardiovascular and cerebrovascular risk, the specific link between normalized serum uric acid (SUA/SCr) and stroke recurrence in patients with impaired renal function has not been well studied. This study aims to fill this gap by investigating the association between SUA/SCr and 1-year stroke recurrence in patients with AIS and abnormal renal function.

Background: The exploration of age-related clinical features and adverse outcomes of non-disabling ischemic cerebrovascular disease (NICE) has been largely unaddressed in current research. This study aimed to analyze the differences in clinical characteristics and prognostic outcomes of NICE across various age groups, utilizing data from the Xi'an Stroke Registry Study in China.

Methods: The age distribution of NICE was categorized into four groups: age ≤ 54 years, age 55-64 years, age 65-74 years, and age ≥ 75 years.

Background: Central retinal artery occlusion (CRAO) is a medical condition characterized by sudden blockage of the central retinal artery, which leads to a significant and often irreversible loss of vision. Observational studies have indicated that diabetes mellitus is a risk factor for CRAO; however, there is no research on the causal relationship between diabetes mellitus, particularly type 2 diabetes, and CRAO. This study aimed to perform Mendelian randomization (MR) analysis to clarify the causal relationship between type 2 diabetes and CRAO.

Background And Purpose: Considering the reliance of serum uric acid (SUA) levels on renal clearance function, its role in stroke outcomes remains controversial. This study investigated the association of renal function-normalized SUA (SUA to serum creatinine ratio, SUA/SCr), a novel renal function index, with the 1-year outcomes in patients with acute ischemic stroke (AIS).

Methods: This is a prospective, multicenter observational study.

Rationale: Ornidazole is a synthetic nitroimidazole derivative that is commonly prescribed for antiparasitic or anti-anaerobic infections. It is generally well tolerated, with known side effects including gastrointestinal tract, anaphylaxis, and central nervous system reactions. Ornidazole-induced binocular reactive keratitis and several mucocutaneous lesions have been rarely reported.

MicroRNA-142-3p (miR-142-3p) has been reported to be implicated in colon cancer; however, the possible regulatory mechanisms and molecular subtypes regulated by miR-142-3p have not been fully elucidated. This study aimed to investigate the biological functions and regulatory mechanism of miR-142-3p in colon cancer. The expression level of miR-142-3p in colon cancer was analyzed based on the mRNA and miRNA expression datasets of colon cancer retrieved from The Cancer Genome Atlas.

Introduction: The triglyceride-glucose (TyG) index is reported to be related to poor functional outcomes and all-cause mortality post-stroke. However, the association between TyG index and recurrent stroke after acute ischemic stroke (AIS) has not been well described. We aimed to identify whether the TyG index was associated with 1-year recurrent stroke after AIS.

Objectives: Evidence on the association between fasting blood glucose and mortality in non-diabetic patients who had a stroke is limited. We aimed to investigate the association of baseline fasting plasma glucose (FPG) with 1 year all-cause mortality in non-diabetic patients with acute cerebral infarction (ACI).

Design: A multicentre prospective cohort study.

Background: Few studies have explored the prognostic role of nontraditional lipid-related indicators in non-disabling ischemic cerebrovascular events (NICE). In this study, we aimed to investigate the relationship between the ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (non-HDL-C/HDL-C) and the1-year risk of recurrent stroke in patients with NICE.

Methods: Total cholesterol (TC), HDL-C, and patient information were collected at admission.

Introduction: This prospective observational study with a control group aimed to compare the plasma levels of long non-coding RNA (lncRNA) LIPCAR between patients with acute cerebral infarction (ACI) and healthy controls, and to assess the prognostic abilities of LIPCAR for adverse outcomes of patients with ACI at 1-year follow-up.

Methods: Eighty patients with ACI, of whom 40 had large artery atherosclerosis (LAA) and 40 had cardioembolism (CE) and who were hospitalized at Xi'an No. 1 Hospital from July 2019 to June 2020, were selected as the case group.

Background: H-type hypertension has a high prevalence in China. However, the association of serum homocysteine levels with 1-year stroke recurrence in patients with acute ischemic stroke (AIS) and H-type hypertension has not been studied.

Methods: A prospective cohort study of patients with AIS admitted to hospitals between January and December 2015 in Xi'an, China, was conducted.

Objective: Henoch-Schönlein purpura nephritis (HSPN) is considered a major cause of chronic renal failure and is the most common secondary glomerular disease in children. Huaiqihuang (HQH), a traditional Chinese herbal formula, exhibits therapeutic effects against HSPN in clinical practice. However, the potential molecular targets and mechanisms underlying HSPN treatment remain unclear.

Despite pitch being considered the primary cue for discriminating lexical tones, there are secondary cues such as loudness contour and duration, which may allow some cochlear implant (CI) tone discrimination even with severely degraded pitch cues. To isolate pitch cues from other cues, we developed a new disyllabic word stimulus set (Di) whose primary (pitch) and secondary (loudness) cue varied independently. This Di set consists of 270 disyllabic words, each having a distinct meaning depending on the perceived tone.

Background: Alkaline phosphatase (ALP) is associated with an increased risk of cardiovascular events and is closely related to adverse outcomes after stroke. However, the regional investigation into the associations of ALP with acute stroke (AS) outcomes is limited. This study aimed to identify the association between serum ALP levels and clinical outcomes 3 months after AS in the Xi'an district of China.

Methionine (MET) dependence is the elevated requirement of cancer cells for MET. Cancer cells are arrested when MET is restricted in late S/G phase of the cell cycle. MET dependence may be the only known general metabolic defect in cancer.

A systematic study using density functional theory has been performed for β-Ga2O3 doped with non-metal elements X (X = C, N, F, Si, P, S, Cl, Se, Br, and I) to evaluate the effect of doping on the band edges and photocatalytic activity of β-Ga2O3. The utilization of a more reliable hybrid density functional, as prescribed by Heyd, Scuseria and Ernzerhof, is found to be effective in predicting the band gap of β-Ga2O3 (4.5 eV), in agreement with the experimental result (4.

Chimpanzees are especially suited to teach us about ourselves, both in terms of their similarities and differences with human, and such important similarities and differences have also been noted for the incidence and severity of several major human diseases. In the present work, we report the entire mitochondrial genome of the Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) for the first time. Results shows that this mitogenome is 16,559 bp long and consists of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 putative non-coding region (D-loop region).

Introduction: Poplar tree gum has a similar chemical composition and appearance to Chinese propolis (bee glue) and has been widely used as a counterfeit propolis because Chinese propolis is typically the poplar-type propolis, the chemical composition of which is determined mainly by the resin of poplar trees. The discrimination of Chinese propolis from poplar tree gum is a challenging task.

Objective: To develop a rapid thin-layer chromatographic (TLC) identification method using chemometric fingerprinting to discriminate Chinese propolis from poplar tree gum.

Objective: Beta blockers and angiotensin-converting enzyme inhibitors are known to attenuate the remodelling process in chronic heart failure, but the high mortality after heart failure must be resolved. We aimed to evaluate the effects of using high thoracic epidural sympathetic blockade (HTESB) as an adjunctive treatment to conventional therapy on the regression of left ventricular remodelling in chronic heart failure due to dilated cardiomyopathy.

Methods: We studied 40 patients with severe chronic heart failure due to dilated cardiomyopathy.
