Identification of circulating miRNA as early diagnostic molecular markers in malignant glioblastoma base on decision tree joint scoring algorithm.

Purpose: The lack of clinical markers prevents early diagnosis of glioblastoma (GBM). Many studies have found that circulating microRNAs (miRNAs) can be used as early diagnostic markers of malignant tumours. Therefore, the identification of novel circulating miRNA biomolecular markers could be beneficial to clinicians in the early diagnosis of GBM.

Exploring the role of Tibetan medicinal formula Qishiwei Zhenzhu Pills (Ranasampel) against diabetes mellitus-linked cognitive impairment of db/db mice through serum pharmacochemistry and microarray data analysis.

Background: Diabetes cognitive impairment (DCI) is a common diabetic central nervous system disorder that severely affects the quality of life of patients. Qishiwei Zhenzhu Pills (Ranasampel) is a valuable Tibetan medicine formula with the ability to improve cerebral blood vessels, protect nerves and improve learning and memory, which has also been widely verified in clinical and basic research. Currently, the prevention and treatment of DCI are still in the exploratory research stage, and the use of Ranasampel will provide new ideas and insights for its treatment.

Mechanism of N-0385 blocking SARS-CoV-2 to treat COVID-19 based on molecular docking and molecular dynamics.

Purpose: 2019 Coronavirus disease (COVID-19) has caused millions of confirmed cases and deaths worldwide. TMPRSS2-mediated hydrolysis and maturation of spike protein is essential for SARS-CoV-2 infection . The latest research found that a TMPRSS2 inhibitor called N-0385 could effectively prevent the infection of the SARS-CoV-2 and its variants.

Outcome of Extracorporeal Membrane Oxygenation Combined with Intraaortic Balloon Pump Hemodynamic Support during the Percutaneous Coronary Intervention Process for Patients with Cardiac Shock Complicating Acute Myocardial Infarction.

We evaluate the effect of extracorporeal membrane oxygenation combined with intraaortic balloon pump mechanical circulatory support for patients with cardiogenic shock complicating acute myocardial infarction during the PCI process. Extracorporeal membrane oxygenation combined with intraaortic balloon pump hemodynamic support during the percutaneous coronary intervention process for patients with cardiac shock complicating acute myocardial infarction might play a complementary role. Yet, evidence of application of both devices at the same time remains unclear.

Efficacy of Shouzhangshen (Rhizoma Gymnadeniae Crassinervidis) extract against acute high altitude hypoxia-induced brain injury in mice.

Objective: To evaluate the protective effect of Shouzhangshen (Rhizoma Gymnadeniae Crassinervidis) extract against acute high altitude hypoxia-induced brain injury in mice.

Methods: Sixty C57BL/6J mice were selected and assigned to six groups (n = 10): normal control group, low-pressure hypoxia group, positive control group (dexamethasone 500 mg/kg), and three groups treated with Shouzhangshen extract (250, 500, and 750 mg/kg, respectively). The Morris water maze test was performed to evaluate alterations in spatial learning and memory deficits.

Expression Profiles of Long Noncoding RNAs in Mice with High-Altitude Hypoxia-Induced Brain Injury Treated with (L.) R. Br.

Background: The unique geographical environment at high altitudes may cause a series of diseases, such as acute altitude reaction, cerebral edema, and pulmonary edema. (L.) R.

Effects of Ethyl Pyruvate on Bile Duct Ligation-Induced Liver Fibrosis by Regulating Nrf2 Pathway and Proinflammatory Cytokines in Rats.

Aim: The aim of this paper is to investigate the effects of ethyl pyruvate (EP) on experimental liver fibrosis induced by bile duct ligation (BDL) and explore the underlying molecular mechanisms.

Material And Method: Rats were randomly divided into three groups: the sham group, the BDL group, and the BDL+EP group. Liver fibrosis was induced by common bile duct ligation and was evaluated by serum biochemical parameter levels, Masson's trichrome staining, -SMA expression, and collagen I deposition.

Hepatoprotective effects of ethyl pyruvate against CCl4-induced hepatic fibrosis via inhibition of TLR4/NF-κB signaling and up-regulation of MMPs/TIMPs ratio.

Background And Aim: Liver fibrosis is a worldwide clinical issue. It has been well established that liver fibrosis is characterized of excessive extracellular matrix (ECM) deposition in chronically damaged livers. Accumulating evidences have suggested that ethyl pyruvate (EP) is a potential useful agent for preventing from hepatic injury.

Remote ischemic postconditioning protects ischemic brain from injury in rats with focal cerebral ischemia/reperfusion associated with suppression of TLR4 and NF-кB expression.

Remote ischemic postconditioning (RIPC) has been proven to be a promising protective method for brain damage caused by transient focal ischemia/reperfusion (I/R) injury. However, the underlying mechanism of RIPC remains elusive. To address whether RIPC protects against brain damage by regulating TLR4 and the NF-κB pathway, focal I/R rat (SD) model induced by 1 h transient middle cerebral artery occlusion was used in this study.

Limb remote ischemic postconditioning protects cerebral ischemia from injury associated with expression of HIF-1α in rats.

Background: Limb remote ischemic postconditioning (LRIP) can ameliorate cerebral ischemia-reperfusion injury (IRI), while the underlying mechanism remains elusive. Hypoxia-inducible factor 1α (HIF-1α) is an important transcription factor during cerebral ischemia damage. However, whether the neuroprotective effect of LRIP could be associated with HIF-1α is somewhat unclear.

Remote ischemic post-conditioning improves neurological function by AQP4 down-regulation in astrocytes.

Cerebral ischemia is a primary cause of human death and long-term disability. Previous studies have suggested that remote ischemic post-conditioning (RIPC) is a potential useful tool for cerebral ischemic treatment. However, the protective mechanism of RIPC is not very clear.
