ABSTRACT
Allergic rhinitis is a kind of nasal mucosal chronic noninfectious inflammatory disease, which is caused by an imbalance in the body cytokine network,a number of intracellular signaling pathways being actived. Many studies have shown that mitogen-activated protein kinase (MAPK) involved in the activation process of allergic rhinitis. p38 mitogen-activated protein kinase (MAPK), as one kind of that, plays a key role in the process of inflammatory cells proliferation and differentiation, as well as production of inflammatory cytokines, and involved in airway inflammatory mechanisms of chronic airway disease. In vitro experiments have confirmed that p38 MAPK inhibitors have anti-inflammatory effect by blocking the downstream related response.

AIM: To investigate the effect of low concentration desflurane on hemodynamics and fibrinolysis in patients during general anesthesia. METHODS: Twenty eight ASA grade Ⅰ-Ⅱ patients during general anesthesia, scheduled for elective chest surgery, were studied, and hemodynamics and fibrinolysis were observed after inhalation of desflurane at 0.5 and 1.0 MAC , respectively. RESULTS: Compared with those before anesthesia, SBP, DBP, and MAP remarkably decreased and HR significantly increased at intubation. However, the changes were more remarkable than those of before anesthesia when inhalation of desflurane at 0.5 and 1.0 MAC ; blood pressure did not further decreased; and HR did not increased in comparison with intubation. The level of plasma tissue plasminogen activator (t PA) remarkably increased and the level of plasma plasminogen activitor inhibitor (PAI) significantly decreased when inhalation of desflurane. The level of plasma t PA further increased and the level of plasma PAI further decreased as inhalation of increased desflurane concentration. CONCLUSION: There are some effects of low concentration desflurane on hemodynamics and fibrinolysis in patients with chest surgery during general anesthesia.
ABSTRACT
Objective To observe the changes of plasma calcitonin gene-related peptide (CGRP) and endothelin (ET) during propofol-induced anesthesia and intubationMethods Thirty-six patients were randomly allocated to receiving intravenous administration with propofol 2mg/kg ( group PP, n=20) or sodium thiopental group (SP, n=16) The venous bloos samples were taken to measure the plasma CGRP and endothelin (ET) concentrations, together with systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR), immediately before induction, 2min after P or SP administration, 2min, 7min, 15min after intubationResults SBP decreased immediately after induction in both groups (P005), increased markedly in group SP (P
ABSTRACT
AIM: To evaluate the antagonistic effect of anti - digoxin antiserum on hypoxic myocardium and its mechanism. METHODS: It was observed that different concentration of anti-digoxin antiserum effect on endoxin and cell membrane ATPase activity in hypoxic myocardium model. RESULTS: The endoxin level was much higher, cell membrane ATPase activity was much lower in hypoxic myocedium than those of noed; anti-digoxin antiserum can resume membrane ATPase activity. CONCLUSION: Rise of endoxin was basic in molecular biology of myocar- dial damage during myocardial hypoxia. Anti - digoxin antiserum decreased myocardial damge and has protective ef- fect on hypoxic myocardium by antagonistic effeCt of endoxin.
