Matrine, an active constituent of the Chinese herb, Sophora flavescens Ait., and it is known for its antioxidant, anti-inflammatory and antitumor activities. It has been demonstrated that matrine exerts protective effects against heart failure by decreasing the expression of caspase-3 and Bax, and increasing Bcl‑2 levels. In this study, we aimed to(More)
A novel triptolide derivative (5R)-5-hydroxytriptolide (LLDT-8) has been shown to have potent immunosuppressive activities. Here LLDT-8 was evaluated in experimental autoimmune encephalomyelitis (EAE), the model of multiple sclerosis (MS). LLDT-8 reduced the incidence and severity of EAE, which was associated with the inhibition of the MOG 35-55 lymphocyte(More)
AIMS OF THE STUDY To investigate the neuroprotective effect of Lycium barbarum polysaccharide (LBP) on focal cerebral ischemic injury in mice and to explore its possible mechanism. MATERIALS AND METHODS Male ICR mice were used to make the model of middle cerebral artery occlusion (MCAO) after intragastric administration with LBP (10, 20 and 40 mg/kg) and(More)
OBJECTIVE To determine whether matrine, a kind of traditional Chinese medicinal alkaloid, can relax the aortic smooth muscles isolated from guinea pigs and to investigate the mechanism of its relaxant effects. METHODS Phenylephrine or potassium chloride concentration-dependent relaxation response of aortic smooth muscles to matrine was studied in the(More)
Oxymatrine (OMT), an active constituent of Chinese herb Sophora flavescens Ait, has been proved to possess anti-tumor, anti-oxidant, anti-inflammatory, and anti-apoptotic activities. Previous study has demonstrated that OMT had protective roles on multiple in vitro and in vivo brain injury models including regulation of apoptosis-related proteins caspase-3,(More)
Aloperine (ALO), one of the alkaloids isolated from Sophora alopecuroides L., is traditionally used for various diseases including neuronal disorders. This study investigated the protective effects of ALO on neonatal rat primary-cultured hippocampal neurons injured by oxygen–glucose deprivation and reperfusion (OGD/RP). Treatment with ALO (25, 50, and 100(More)
This paper discusses how to reveal the cognitive operation of human being from the perspective of granular computing, and discusses the uncertainty, ambiguity and other basic issues of cognition, and distinguishes, judges and identifies its link with thought operation. Human brain can only receive messages of different sensory attributes. A thing's state,(More)
We report that Mucin1 (MUC1), a transmembrane glycoprotein that is overexpressed in >80% of pancreatic ductal adenocarcinoma (PDA), induced a pro-angiogenic tumor microenvironment by increasing the levels of neuropilin-1 (NRP1, a co-receptor of vascular endothelial growth factor (VEGF)) and its ligand VEGF. Expression of tumor-associated MUC1 (tMUC1)(More)
Chemotherapy drugs such as vincristine (VCR) can cause neuropathic pain, and there is still lack of ideal strategy to treat it. The current study was designed to investigate effect of matrine (MT) on VCR-induced neuropathic pain in animal model. VCR (75 μg/kg, i.p. for 10 consecutive days) was administered to induce painful neuropathy model in mice. MT (15,(More)
Ischemia stroke is the major cause of mortality and permanent neurological disability with little definitive therapeutic options. This cerebral ischemic injury leads to the oxidative stress and eventually cell death. We hypothesized that treatment of this condition with the trans-cinnamaldehyde(TC) could protect cells from ischemic and reperfusion injury.(More)
