Coronary atherosclerosis (or coronary heart disease [CHD]) is a common cardiovascular disease that seriously damages human health. Percutaneous coronary stent implantation represents the primary treatment option for severe CHD in clinical practice; meanwhile, dual antiplatelet therapy (DAPT) is widely used to reduce the risk of postoperative thrombosis. Although the mechanisms of action of the two most commonly used antiplatelet drugs, aspirin and clopidogrel, remain unclear, clinical studies have shown that some patients are susceptible to stent thrombosis-antiplatelet resistance (high on-treatment platelet reactivity [HTPR])-despite using these drugs.

Article Synopsis
  • Scrub typhus, caused by Orientia tsutsugamushi, is a serious disease that can lead to various complications, but central nervous system involvement is rare.
  • A 17-year-old male with fever and headaches was initially diagnosed with a CNS infection, but standard treatments weren't effective, leading to further testing.
  • The diagnosis was updated to scrub typhus with meningitis after detecting the pathogen, and treatment with doxycycline led to a successful recovery, highlighting the importance of considering scrub typhus in similar patient cases.

We explored the effects of curcumin on the aberrant biological behaviors of prolactinoma cells and the downstream pathways through which curcumin exerts its antitumor effects. We used quantitative reverse transcription-polymerase chain reaction assays to measure miR-206 expression levels in peripheral blood samples from patients with prolactinoma before and after curcumin treatment. We also investigated the proliferation level, viability, and invasion ability of groups of cells treated with different concentrations of curcumin using 3-(4,5)-dimethylthiahiazo (-z-y1)-3-di-phenytetrazoliumromide (MTT) assays, cell cloning assays, and Transwell assays, respectively.

Studies have shown that a series of molecular events caused by oxidative stress is associated with ferroptosis and oxidation after ischemic stroke (IS). Differential analysis was performed to identify differentially expressed mRNA (DEmRNAs) between IS and control groups. Critical module genes were identified using weighted gene co-expression network analysis (WGCNA).

  • rTMS has the potential to improve recovery in individuals with poststroke aphasia (PSA), but previous studies haven't pinpointed the best treatment parameters for maximum effectiveness.
  • This meta-analysis reviewed data from 18 randomized controlled trials totaling 387 participants to determine the optimal rTMS variables for treating PSA.
  • Findings suggest a trend indicating that higher total pulses (40,000) correlate with better treatment outcomes, although other variables showed no significant correlations.

Article Synopsis
  • The study aimed to explore changes in brain network organization in patients with chronic low back pain (CLBP) and how these changes relate to their pain experiences.
  • Using fMRI scans and graph theory, researchers compared the brain connectivity patterns of 33 CLBP patients to 34 healthy controls, finding significant differences in whole-brain functional connectivity.
  • Results showed that CLBP patients exhibited decreased functional efficiency and connectivity, particularly in areas related to pain processing, suggesting these brain alterations could inform pain management strategies.

Dysfunction of the cingulo-frontal-parietal (CFP) cognitive attention network has been associated with the pathophysiology of chronic low back pain (cLBP). However, the direction of information processing within this network remains largely unknown. We aimed to study the effective connectivity among the CFP regions in 36 cLBP patients and 36 healthy controls by dynamic causal modeling (DCM).

Chronic nonspecific low back pain (cNLBP) is a leading contributor to disease burden worldwide that is difficult to treat due to its nonspecific aetiology and complexity. The amygdala is a complex of structurally and functionally heterogeneous nuclei that serve as a key neural substrate for the interactions between pain and negative affective states. However, whether the functions of amygdalar subcomponents are differentially altered in cNLBP remains unknown.

Due to the rarity of hemolymphangioma, a limited number of cases of the disease have been reported in the literature thus far. The present case report describes the cases of 4 patients with hemolymphangioma that were diagnosed and treated at the Second Affiliated Hospital of Xi'an Jiaotong University (Xi'an, China). All patients were female, with a mean age of 44.

Aim: To investigate wall shear stress (WSS) magnitude and distribution in cirrhotic patients with portal hypertension using computational fluid dynamics.

Methods: Idealized portal vein (PV) system models were reconstructed with different angles of the PV-splenic vein (SV) and superior mesenteric vein (SMV)-SV. Patient-specific models were created according to enhanced computed tomography images.

Objective: To explore the morphometric abnormalities of brain gray matter (GM) in patients with chronic low back pain (CLBP).

Methods: Thirty patients with CLBP and 30 healthy individuals were enrolled and examined with a 3.0 T magnetic resonance (MR) scanner.

Despite the involvement of subcortical brain structures in the pathogenesis of chronic pain and persistent pain as the defining symptom of knee osteoarthritis (KOA), little attention has been paid to the morphometric measurements of these subcortical nuclei in patients with KOA. The purpose of this study is to explore the potential morphological abnormalities of subcortical brain structures in patients with KOA as compared to the healthy control subjects by using high-resolution MRI. Structural MR data were acquired from 26 patients with KOA and 31 demographically similar healthy individuals.

Pituitary tumors, the most common intracranial tumors, lead to serious morbidity through the inappropriate secretion of pituitary hormones. The anomalous expression of microRNAs (miRNAs), which have a crucial status in the development and function of pituitary gland, promotes the tumorigenesis of hypothalamic-pituitary axis-related pituitary tumors. This mainly leads to alterations in the function of the hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-gonadal axis and hypothalamic-pituitary-growth hormone.

Aim: To evaluate the value of quantitative diffusion tensor imaging (DTI) in assessing the axonal and myelin damage of the optic nerves and optic radiations in patients with chronic primary angle-closure glaucoma (PACG) by using high-field magnetic resonance (MR) imaging (3T).

Methods: Twenty patients with bilateral chronic PACG and twenty age- and sex matched disease-free control subjects were enrolled. Conventional MRI and DTI were performed on all subjects using 3T MR scanner.

Objective: To explore the diffusion-tensor imaging (DTI) characteristics of normal-appearing white matter (NAWM) and normal-appearing gray matter (NAGM) on conventional magnetic resonance imaging (MRI) in patients with subcortical ischemic vascular disease (SIVD) and examine the relation of such features with the general cognitive function of the patients.

Methods: DTI was performed in 46 SIVD patients and 34 age-matched control subjects with normal MRI findings. The apprarent diffusion coeeficient (ADC) and fractional anisotropy (FA) were measured within the regions of white matter lesions (WMLs), NAWM and NAGM.

Parkinson's disease is a commonly encountered central nervous retrograde affection in elder persons. According to the theories of traditional Chinese medicine, Parkinson's disease is characterized by deficiency in the Ben (root) and excess in the Biao (branch). The Ben (root) is insufficiency of liver and kidney and deficiency of qi and blood; and the Biao (branch) is wind, fire, phlegm and stasis.
