To investigate the interleukin 10 (IL 10) content in plasma in rats with acute lung injury(ALI) induced by oleic acid (OA) and lipopolysaccharide(LPS). OA (0.2ml/kg) and LPS (2mg/kg) was given to Wister rats to produce ALI. The respirtory rate,PaO 2 , wet weight/dry weight (W/D) of the lung, and pathological changes were observed, and IL 10 was determined with enzyme linked immunosorbent assay (ELISA). The results showed that ALI was produced in rats with OA+LPS, and there was a significant increase in IL 10 content in plasma in rats, especially in OA+LPS/4h group. The above results suggested that OA+LPS might produce ALI in rats, and the development of ALI was related to an obvious increase of the IL 10 content in plasma.

To investigate the interleukin 13(IL 13) content in plasma in rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS), Wistar rats were given increasing doses of LPS (2mg/kg,4mg/kg,6mg/kg,8mg/kg) to produce ALI. The respirtory rate,PaO 2 ,wet weight/dry weight (W/D) of the lung, and pathological changes in the lung were observed. ELISA was used to determine plasma IL 13. It was found that: (1)ALI could be produced in rats with LPS, but ARDS occurred only when the dose of LPS reached 6mg/kg. or larger. (2)LPS produced an elevation of the content of IL 13 in plasma in rats, peaking when the dose of LPS reaching 6mg/kg or over. These results suggested that LPS might induce ALI in rats, and ARDS could be produced when the dose of LPS reached ≥6mg/kg. (3)The high increase in plasma IL 13 content might play an important role in producing ARDS induced by LPS.

Objective To study the effects of allogeneic blood transfusion on expression of CD40L on peripheral blood monocytes (PBMCs) in patients undergoing radical gastrectomy for gastric carcinoma. Methods Thirty patients classified as ASA physical status Ⅰ- Ⅱ undergoing radical gastrectomy for gastric carcinoma were randomly divided into three groups with 10 patients in each group : group A received no allogeneic blood; group B received leukodepleted blood; group C received allogeneic whole blood during operation or within 12 h after operation. The patients were premedicated with intramuscular phenobarbital sodium 0.1 g and atropine 0.5 mg. Anesthesia was induced with midazolam 0.06 mg ? kg-1 , fentanyl 2 ?g ?kg-1 , propofol 1.5 mg ?kg-1 and vecuronium 8mg and maintained with continuous infusion of propofol (100?g?kg-1?min-1) and vecuronium (5?g ?kg-1?min-1) and intermittent inhalation of 1l%-2% isoflurane. The patients were mechanically ventilated after tracheal intubation. Blood samples were taken before operation and 2, 5 and 10 days after operation. The PBMCs and plasma were separated from peripheral blood by Ficoll-Hypaque centrifugation. The PBMCs were washed and incubated with the patients own plasma (final-concentration 10% ) and PHA (final concentration 20 ?g?ml-1 ) at 37℃ in a 5% CO2 atmosphere for 48h. CD40Lexpression on PBMCs was quantified by flow-cytometry.Results The demographic data including sex, age, bodyweight and duration of operation and intraoperative blood loss were comparable among the three groups. There was no significant difference in the CD40L expression before operation among the 3 groups. In group A there was no change in CD40L expression after operation. In group B CD40L expression on PBMCs increased significantly on the 2nd postoperative day, but returned to preoperative level on the 5th postoperative day. In group C the CD40L expression on PBMCs kept increasing on the 2nd and 5th postoperative day and did not return to preoperative level on the 10th day. The increase in CD40L expression was significantly larger in group C than that in group B ( P

Objective To explore the effect of GAS MAN assisted instruction on theory learning of volatile anesthetics in anesthesiology residency training.Methods A total of 32 residents in the first stage of anesthesiology training were enrolled and randomly assigned to either study(S) or control (C) group.Theory-test l(Test-1) was conducted for all residents after the lecture-based learning (LBL).Next,reference book self-reading strategy was used in both groups while computer-based simulation(CBS) using GAS MAN was only developed in S group.Then,theory-test 2(Test-2)was conducted for residents in both groups and residents in S group completed the questionnaire smvey.In addition,thirty-four resident teachers observed the CBS courses and completed the questionnaire smvey.Results The mean scores of Test-1 did not differ significantly between the two groups(P=0.64).However,the mean Test-2 score of S group(81.3 ± 13.6) was significantly higher than that of C group(61.3 ± 15.4) (P=0.001).100％(16/16) residents believed that CBS was beneficial to the theoretical study of volatile anesthetics,93.8％(15/16) residents considered GAS MAN could help understand the concepts and improve efficiency during self-learning.97.1％ (33/34) and 91.2％ (31/34)resident teachers agreed that CBS was helpful for analyzing complex concepts and improving study effectiveness,respectively.Conclusions CBS using GAS MAN improves theory knowledge and study effectiveness for anesthesia residents.Both residents and resident teachers find GAS MAN highly ac ceptable.Therefore,GAS MAN has the potential to be the assistant teaching tool for LBL in anesthesiology residency-training program.

AAIM:To investigate the effect of atorvastatin ( ATO) on electrical remodeling, atrial ion channel protein expression and cardiac function in atrial tachypacing rabbits, and to explore the potential electrical mechanism of ATO in the prevention of atrial fibrillation.METHODS:The rabbits were subjected to atrial tachypacing at 600 min-1 in the absence or presence of treatment with atorvastatin (ATP and ATO groups) for 48 h, and the other 10 as sham group without pacing ( NP group) .The tachypacing model was performed by attaching pacing and testing electrodes to left atrial and connecting with custom animal cardiac pacemaker in the open-chest situation.The animals in ATO group were pretrea-ted with ATO for 7 d and continued during tachypacing.Serial atrial effective refractory period ( AERP) was measured in each rabbit at baseline, 8 h, 16 h, 24 h, 32 h, 40 h and 48 h with different cycle lengths.The changes of cardiac func-tions and cardiac structure were observed by cardiac ultrasonic cardiogram before and after atrial tachypacing.The expres-sion of atrial ion channel proteins CaLα1 and Kv4.3 was detected by Western blotting.RESULTS:Compared with NP group, AERP at cycle lengths of 150 and 200 ms, the adaption of AERP, and the levels of CaLα1 and Kv4.3 expression were all decreased in ATP and ATO group, especially in ATP group.Left atrial dimension ( LAD) was increased in pacing groups as compared with NP group (P<0.05) after pacing delivery for 48 h, while no difference between the formers was observed.No significant change of the left ventricular dimension ( LVD) and ejection fraction ( LVEF) among groups be-fore and after pacing was found.CONCLUSION:Atrial tachypacing significantly shorten AERP, resulting in poor adap-tion of AERP, while ATO pretreatment significantly attenuates the atrial electrical remodeling in rabbits, but had no effect on cardiac structure.ATO suppresses the down-regulation of atrial ion channel proteins CaLα1 and Kv4.3 expression after 48 h, which may be the potential ionic mechanism of atrial electrical remodeling for ATO.
