Serum adropin levels are decreased in patients with acute myocardial infarction.

Objective: Adropin is a recently identified bioactive protein that is important for energy homeostasis and maintaining insulin sensitivity. We sought to detect serum adropin levels in acute myocardial infarction (AMI) patients.

Methods: We enrolled 138 AMI patients, 114 stable angina pectoris (SAP) patients and 75 controls.

Combined treatment with bone marrow mesenchymal stem cells and methylprednisolone in paraquat-induced acute lung injury.

Background: To evaluate the efficacy of combined treatment with bone marrow mesenchymal stem cell (BMSC) transplantation and methylprednisolone (MP) to treat paraquat (PQ)-induced acute lung injury.

Materials And Methods: A total of 102 female rats were randomly divided into five groups: PQ, BMSC, MP, BMSC + MP and normal control. After 14 days of PQ poisoning, the survival of rats, wet/dry weight ratio of lung tissue, serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-10, malondialdehyde (MDA) and superoxidase dismutase (SOD), and the expression of nuclear factor (NF)-кB p65 in lung tissue were determined.

[Optimal conditions of bone marrow mesenchymal stem cells on paraquat-induced acute lung injury in rats].

Objective: To investigate the effect of bone marrow mesenchymal stem cell (BMSC) transplantation on acute lung injury induced by paraquat (PQ) poisoning in rats, and to identify the optimal transplantation conditions.

Methods: Two hundred female rats were randomly divided into six groups, i.e.

Suppressive effects of intrathecal paeoniflorin on bee venom-induced pain-related behaviors and spinal neuronal activation.

Recently, paeoniflorin (PF) administered systemically was found to have analgesic effects against inflammatory pain and hypersensitivity in a naloxone-reversible manner. In the present study, we adopted intrathecal administration to evaluate whether PF has direct antinociceptive actions at the spinal level. Pain-related behaviors and spinal c-Fos expression were induced by subcutaneous injection of bee venom (BV) into one hind paw of a rat.

Protection of bone marrow mesenchymal stem cells from acute lung injury induced by paraquat poisoning.

OBJECTIVE. To examine the protective effect of bone marrow mesenchymal stem cell (BMSC) transplantation against lung injury induced by paraquat (PQ) poisoning. MATERIALS AND METHODS.

Antinociceptive effects of systemic paeoniflorin on bee venom-induced various 'phenotypes' of nociception and hypersensitivity.

Paeoniflorin (PF), one of the active chemical compounds identified from the root of Paeonia lactiflora Pall, has been well-established to exhibit various neuroprotective actions in the central nervous system (CNS) after long-term daily administration. In the present study, by using the bee venom (BV) model of nociception and hypersensitivity, antinociceptive effects of PF were evaluated by intraperitoneal administration in conscious rats. When compared with saline control, systemic pre- and post-treatment with PF resulted in an apparent antinociception against both persistent spontaneous nociception and primary heat hypersensitivity, while for the primary mechanical hypersensitivity only pre-treatment was effective.

Region- or state-related differences in expression and activation of extracellular signal-regulated kinases (ERKs) in naïve and pain-experiencing rats.

Background: Extracellular signal-regulated kinase (ERK), one member of the mitogen-activated protein kinase (MAPK) family, has been suggested to regulate a diverse array of cellular functions, including cell growth, differentiation, survival, as well as neuronal plasticity. Recent evidence indicates a role for ERKs in nociceptive processing in both dorsal root ganglion and spinal cord. However, little literature has been reported to examine the differential distribution and activation of ERK isoforms, ERK1 and ERK2, at different levels of pain-related pathways under both normal and pain states.
