[Research progress in pathogenesis and traditional Chinese medicines treatment of ischemic stroke-related headache].

Headache is a common clinical complication of ischemic stroke. As a precursor of stroke, headache occurs repeatedly in the convalescent period of ischemic stroke, leading to secondary stroke and seriously hindering patients' rehabilitation. Currently, it is believed that the pathogenesis of ischemic stroke-related headache is associated with the abnormal release of vasoactive substances, high platelet aggregation, and stimulation of intracranial pain-sensitive structures.

Circulating circular RNA profiles associated with celiac disease seropositivity in children with type 1 diabetes.

Introduction: The frequency of celiac disease autoantibody (CDAb) positivity in type 1 diabetes (T1D) has increased due to unclear mechanisms, including autoimmune injury. Circular ribonucleic acids (circRNAs) participate in autoimmune diseases, but the roles of circRNAs in T1D with CDAbs are currently unknown. This study aimed to determine the frequency of CDAbs in Chinese children with T1D and describe the relationship between CDAbs and circRNAs.

Ureteroscopic Lithotripsy in Reverse Trendelenburg Position and Intraoperative Furosemide.

Purpose: Upward stone migration is a significant problem during ureteroscopic lithotripsy (URSL) for upper ureteral stone, especially in absence of a ureteral occlusion device.

Observational Insights into Isoprene Secondary Organic Aerosol Formation through the Epoxide Pathway at Three Urban Sites from Northern to Southern China.

Isoprene is the most abundant precursor of global secondary organic aerosol (SOA). The epoxide pathway plays a critical role in isoprene SOA (iSOA) formation, in which isoprene epoxydiols (IEPOX) and/or hydroxymethyl-methyl-α-lactone (HMML) can react with nucleophilic sulfate and water producing isoprene-derived organosulfates (iOSs) and oxygen-containing tracers (iOTs), respectively. This process is complicated and highly influenced by anthropogenic emissions, especially in the polluted urban atmospheres.

Tropism and transduction of oncolytic adenovirus vectors in prostate cancer therapy.

Oncolytic adenovirus has been applied in cancer therapy because of several advantages such as cost-effective production, high transduction efficiency and low toxicity. Recent efforts have been focused on the modification of oncolytic adenovirus by encoding transgenes within the viral genome to efficiently and selectively replicate within cancer cells, destroy cancerous cells, induce tumor cell apoptosis, and stimulate the recruitment of immune cells to the tumor site. Nevertheless, there are still big challenges for translational research of oncolytic virotherapy in clinical cancer management.

[Strategies for efficacy and function positioning of new resources of Chinese materia medica].

Chinese materia medica( CMM) serves as an important cornerstone for the development of traditional Chinese medicine( TCM) culture and industry due to its unique ecological,medical,economic,scientific and technological,and cultural values.

Development and Preliminary Clinical Application of Circulating Tumor Cell Detection System for Prostate Cancer.

Real-time detection of circulating tumor cell (CTC) markers that are constantly changing and renewing during disease progression is of great significance for the timely regimen switch or individualized target therapy. The abnormally expressed special AT-rich sequence binding protein 1 (SATB1), a nuclear matrix attachment region binding protein, in various tumors, promotes the growth and metastasis of tumor cells by regulating gene expression. In this paper, a CTC detection system for prostate cancer (PCa) was developed on the basis of epithelial cell adhesion molecule (EpCAM)-targeted immunomagnetic separation and CK-FITC and SATB-1-APC immunofluorescence assay, and the recovery rate of tumor cells in PBS and simulated whole blood by this system was detected.

Effect of silencing the T‑Box transcription factor TBX2 in prostate cancer PC3 and LNCaP cells.

T‑Box (TBX)‑2 is a member of the T‑box gene family, which is aberrantly expressed in numerous types of malignant tumors, and has previously been demonstrated to be conducive to tumor progression by acting as a transcription factor. However, specific information regarding the expression and function of TBX2 in prostate cancer cells remains to be elucidated. The present study demonstrated that silencing of TBX2 by TBX2 small interfering RNA inhibited cell proliferation and promoted cell senescence.

Significant Increase of Aromatics-Derived Secondary Organic Aerosol during Fall to Winter in China.

Human activities release large amounts of anthropogenic pollutants into the air, and thereby produce substantial secondary organic aerosol (SOA). Aromatic hydrocarbons (AHs) that mainly emitted from coal combustion, transportation, solvent use and biofuel/biomass burning, are a major class of anthropogenic SOA precursors. At present, there are few field studies focusing on AH-derived SOA (SOA) on a continental scale, especially in polluted regions of the world.

Comprehensive evaluation of the liquid fraction during the hydrothermal treatment of rapeseed straw.

Background: The requirement for efficient and green conversion technologies has prompted hydrothermal processing as a promising treatment option for sustainable biorefinery industry. The treatment has been applied to process plenty of lignocellulose materials, yielding abundant high value-degraded products, especially the products in the liquid fraction. Therefore, it is essential to systematically evaluate the degraded products in aqueous fraction by comprehensive analysis and structural characterization during the treatment.
