Objective To investigate the level change of interleukin-4(IL-4) and IL-12, and their effect on airway inflammation in rat asthma. Methods Rat model of asthma was set up by ovalbumin sensitization. Total cell count and eosinophil count in branchoalveolar lavage fluid(BALF) were performed, and levels of IL-4 and IL-12 in BALF were measured by ELISA. Results After ovalbumin sensitization, airway occurred obvious inflammation. Eosinophil count began increasing at 1 hour after sensitization, obviously increased at 8 hours, reached a maximum at 24 hours, started declining at 96 hours, and decreased to near normal range at 7 to 14 days. The changes of total cell count had the same tendency as eosinophil count changes. The level of IL-4 in BALF elevated at 1h after sensitization, reached a maximun at 8 to 96 hours, and reduced to near normal level at 7 to 14 days. The changes of IL-12 in BALF had the same tendency as IL-4 level changes. Eosinophil count was positively related with IL-4 level(r=0.74,P0.05). There was a close correlation between IL-4/IL-12 ratio and eosinophil count (r=0.85,P

Objective To compare the feasibility and efficacy between dexmedetomidine and midazolam in herniorrhaphy surgery for older patients. Methods Sixty American Society of Anesthesiology (ASA) gradeⅠ~Ⅱpatients, treated by herniorrhaphy surgery under local anesthesia,were randomly divided into dexmedetomidine group (n=30) and midazolam group (n=30) .Patients in dexmedetomidine group were given dexmedetomidine at a loading dose of 1μg/kg for 10 min,then they were injected continuously by 0.4μg/(kg·h),whereas midazolam group were given midazolam at a loading dose of 0.06 mg/kg, then 0.04 mg/(kg·h) injected continuously.The mean blood pressure (MAP) and heart rate (HR) were recorded before infusion (T0),incision of skin (T1),15min (T2) and 30 min (T3) after administration and when sutured skin (T4), adverse reaction were also assessed. Results The difference of sedation level was not significant between the two groups (P>0.05) .Compared with T0 , the decrease of HR was significantly more in dexmedetomidine group from T1 to T4 (P<0.05) . Compared with midazolam group , the decrease of HR was significantly more in dexmedetomidine group from T1 to T4 (P<0.05) . Compared with dexmedetomidine group, the rate of respiratory depression and restlessness were more in midazolam group, but bradycardia was lower (P<0.05) .Conclusions Dexmedetomidine is a comparable alternative to midazolam for sedation in herniorrhaphy surgery under local anesthesia. It is associated with better respiration and lower restlessness but with a high incidence of bradycardia.
