GRK2-mediated phosphorylation and de-succinylation of PKM2 reduce macrophage glycolysis in rheumatoid arthritis.

Glucose metabolism disorder is an important hallmark of rheumatoid arthritis (RA). Inhibiting key glycolysis enzymes is the primary approach, but effective treatments targeting glycolytic metabolism have not yet reached clinical practice. G protein-coupled receptor kinase 2 (GRK2) as a multi-signals regulatory hub has attracted wide attention.

A new machine learning model to predict the prognosis of cardiogenic brain infarction.

Cardiogenic cerebral infarction (CCI) is a disease in which the blood supply to the blood vessels in the brain is insufficient due to atherosclerosis or stenosis of the coronary arteries in the patient's heart, which leads to neurological deficits. To predict the pathogenic factors of cardiogenic cerebral infarction, this paper proposes a machine learning based analytical prediction model. 494 patients with CCI who were hospitalized for the first time were consecutively included in the study between January 2017 and December 2021, and followed up every three months for one year after hospital discharge.

The global prevalence of highly pathogenic avian influenza A (H5N8) infection in birds: A systematic review and meta-analysis.

The zoonotic pathogen avian influenza A H5N8 causes enormous economic losses in the poultry industry and poses a serious threat to the public health. Here, we report the first systematic review and meta-analysis of the worldwide prevalence of birds. We filtered 45 eligible articles from seven databases.

CP-25, a compound derived from paeoniflorin: research advance on its pharmacological actions and mechanisms in the treatment of inflammation and immune diseases.

Total glycoside of paeony (TGP) has been widely used to treat inflammation and immune diseases in China. Paeoniflorin (Pae) is the major active component of TGP. Although TGP has few adverse drug reactions, the slow onset and low bioavailability of Pae limit its clinical use.

Predicting the One-Year Prognosis and Mortality of Patients with Acute Ischemic Stroke Using Red Blood Cell Distribution Width Before Intravenous Thrombolysis.

Purpose: Red blood cell (RBC) distribution width (RDW) is known to reflect the heterogeneity of RBC volume, which may be associated with cardiovascular events or mortality after myocardial infarction. However, the association between RDW and stroke, especially regarding endpoints such as death, remains ambiguous. This study aimed to explore the prognostic value of RDW and its effect on mortality among patients with acute ischemic stroke (AIS) undergoing intravenous thrombolysis (IVT) after one year.

PM induces vascular permeability increase through activating MAPK/ERK signaling pathway and ROS generation.

Although in-vivo exposure of PM has been suggested to initiate a disorder on vascular permeability, the effects and related mechanism has not been well defined. In this work, an obvious increase on vascular permeability has been confirmed in vivo by vein injection of PM into Balb/c mouse. Human umbilical vein vascular endothelial cells and the consisted ex-vivo vascular endothelium were used as model to investigate the effects of PM on the vascular permeability and the underlying molecular mechanism.

Effects of Pulsatile Cupping on Body Pain and Quality of Life in People with Suboptimal Health:A Randomized Controlled Exploratory Trial.

The curative effect of pneumatic pulsatile cupping on pain has been shown. This study was conducted to investigate effects of the pulsating frequency of pneumatic pulsatile cupping, compared with traditional cupping (TC), on body pain and quality of life (QoL) in people with suboptimal health status (SHS). Ninety-six participants with SHS were randomized to low-frequency (LF;  = 24) or high-frequency (HF;  = 24) pulsating cupping, traditional cupping (TC;  = 24), or wait-list (WL;  = 24) groups.

CP-25 reverses prostaglandin E4 receptor desensitization-induced fibroblast-like synoviocyte dysfunction via the G protein-coupled receptor kinase 2 in autoimmune arthritis.

Paeoniflorin-6'-O-benzene sulfonate (CP-25) is a novel compound derived from paeoniflorin that has been demonstrated to have therapeutic effects in a rat model of rheumatoid arthritis (RA). However, the underlying mechanism has not been elucidated to date. We explored this mechanism in the present study by treating rats with adjuvant arthritis (AA) with CP-25.

Three-Case Report of Embolic Stroke of Undetermined Source.

Background: Embolic stroke of undetermined source (ESUS) is a new clinical construct. It signifies that the embolus in the thromboembolic ischemic stroke is of unknown origin. The anticoagulants are usually prescribed for antithrombotic prophylaxis, but whether it is appropriate for all patients with ESUS is still unknown.

A new biocompatible microemulsion increases extraction yield and bioavailability of Andrographis paniculata.

The purpose of this study was to design and prepare a biocompatible microemulsion of Andrographis paniculata (BMAP) containing both fat-soluble and water-soluble constituents. We determined the contents of active constituents of BMAP and evaluated its bioavailability. The biocompatible microemulsion (BM), containing lecithin and bile salts, was optimized in the present study, showing a good physical stability.

Endothelial Dysfunction and Inflammation: Immunity in Rheumatoid Arthritis.

Inflammation, as a feature of rheumatoid arthritis (RA), leads to the activation of endothelial cells (ECs). Activated ECs induce atherosclerosis through an increased expression of leukocyte adhesion molecules. Endothelial dysfunction (ED) is recognized as a failure of endothelial repair mechanisms.

Design and application of pulse information acquisition and analysis system with dynamic recognition in traditional Chinese medicine.

Background: To design the pulse information which includes the parameter of pulse-position, pulse-number, pulse-shape and pulse-force acquisition and analysis system with function of dynamic recognition, and research the digitalization and visualization of some common cardiovascular mechanism of single pulse.

Methods: To use some flexible sensors to catch the radial artery pressure pulse wave and utilize the high frequency B mode ultrasound scanning technology to synchronously obtain the information of radial extension and axial movement, by the way of dynamic images, then the gathered information was analyzed and processed together with ECG. Finally, the pulse information acquisition and analysis system was established which has the features of visualization and dynamic recognition, and it was applied to serve for ten healthy adults.

[A new opinion on detection methods for pulse shape and pulse force].

Pulse shape and pulse force are difficult to detect in pulse taking study. But the application of visualized technology extends the space acquisition of pulse taking information, and it is possible to realize the objective detection of pulse shape and pulse force. Rational research thoughts and strategies could be informed by combining image information and other data, and it is a necessary method in implementing the objective detection of pulse.

[Discussion on methods for searching traditional Chinese medical literature in English in PubMed-MEDLINE database].

The methods for searching traditional Chinese medical literature in English with subject headings in PubMed-MEDLINE database were discussed from the practical view, and seven useful searching methods with free words according to practical experiences were put forward in order to assist the domestic TCM researchers to utilize PubMed-MEDLINE database in searching overseas TCM literature in English.
