AIM To study the synaptic mechanisms involved in the 5-hydroxytryptamine1A/7 (5-HT1A/7) receptor-mediated reflex control of cardiac vagal preganglionic neurons (CVPN). METHODS CVPN were retrogradely labeled and identified in brain stem slices of newborn rats, and their synaptic activity was examined using whole-cell patch-clamp. RESULTS(More)
The glutamatergic innervations and the GABAergic innervations are respectively the major excitatory and inhibitory inputs of preganglionic cardiac vagal neurons (CVNs). Whether and how these two kinds of innervations interact in the regulation of CVNs is unknown. Using retrograde fluorescent labeling of CVNs and voltage patch-clamp technique, we(More)
This study was first designed to investigate systematically the kinetics of surface expression of scavenger receptors (SRs) and CD14 on alveolar macrophages in vivo and in vitro and their relation with local pro- and antiinflammatory responses in endotoxemia. The expression of SR and CD14 in lungs was down- and up-regulated, respectively, in the presence of(More)
In the present study, we aimed to investigate the effects of CC chemokine ligand 22 (CCL22) and interleukin-37 (IL-37) on the proliferation and epithelial-mesenchymal transition (EMT) of non-small cell lung cancer (NSCLC) A549 cells. pDsRed-CCL22 and pEGFP-IL-37 plasmids were constructed. A549 cells were divided into six groups: the control, the pDsRed-N1(More)
OBJECTIVE To investigate the changes of scavenger receptor (SR) and CD14 in Kupffer cells in endotoxemia in order to uncover the mechanism of the liver to turn a defense organ into effector one in sepsis. METHODS Mouse models of endotoxemia of different severity were reproduced by injection of different doses of lipopolysaccharide (LPS) via the tail vein.(More)
BACKGROUND Recent epidemiologic studies have focused on the potential beneficial effects of regional anesthetics, and the differences in cancer prognosis may be the result of anesthetics on cancer biologic behavior. However, the function and underlying mechanisms of lidocaine in hepatocellular carcinoma both in vitro and in vivo have been poorly studied. (More)
Little is known about how gap junctions are involved in the respiratory-related or other types of physiological neuronal activity since physiologically active gap junction currents (GJCs) have never been characterized from single respiratory-related neurons or from single neurons of any other types. In the present study we hypothesized that GJCs could be(More)
BACKGROUND The serum uric acid (SUA) is the end-product from the metabolic breakdown of purine nucleotides. It has been considered to be a prognostic factor for malignant tumor in several researches. However, its prognostic value in patients with esophageal squamous cell carcinoma (ESCC) has not been elucidated. METHODS We retrospectively reviewed the(More)
AIM To test the effect of orexin-A (hypocretin-1), a neuropeptide synthesized in the lateral hypothalamus and the perifornical area, on the glycinergic inputs and the GABAergic inputs of cardiac vagal neurons (CVN). METHODS The effects of orexin-A at three concentrations (20 nmol/L, 100 nmol/L, 500 nmol/L) on the glycinergic inputs and the GABAergic(More)
