Chinese Journal of Anesthesiology 2009;29(10):932-934
Objective To investigate the effect of adenoviral-mediated interleukin-10 (IL-10) gene transfection on systemic inflammatory responses in a rat model of ventilator-induced lung injury. Methods Thirty adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n=6 each): group Ⅰ control (group C); group Ⅱ adenovirus without IL-IO gene + 2 h mechanical ventilation (MV) (group B, ); group II1 adenoviruswithout IL-IO gene + 4 h MV (group B_2); group Ⅳ adenovirus with IL-10 gene + 2 h MV (group A_1) and group Ⅴ adenovirus with IL-10 gene + 4 h MV (group A_2). In group Ⅱ-Ⅴ the animals were mechanically ventilated (airway pressure = 25 cm H_2 O) and adenovirus was injected into right ventricle at 48 h before MV. Blood samples were taken from abdominal aorta at the end of 2 h or 4 h MV for determination of serum IL-8 and IL-10 concentrations. The animals were then killed. The pulmonary specimens were obtained for examination of ultrastructure with light and electron microscope. Results Mechanical ventilation significantly increased serum IL-8 and IL-IO concentrations in a duration-dependent manner in group Ⅱ-Ⅴ as compared with group C. Trans-pulmonary administration of adenoviraI-mediated interleukin-10 gene significantly decreased serum IL-8 concentration and increased serum IL-10 concentration and reduced ventilator-induced lung injury alter MV in group A_1 and A_2 as compared with group B_1 and B_2. Conclusion Adenoviml-madiated IL-10 gene transfection can attenuate the systemic inflammatory response and reduce ventilator-induced lung injury.

Chinese Journal of Radiology 2009;43(11):1135-1138
Objective To investigate the predictive value of ADC value in grading of neuroepithelial tumors. Methods The clinical data and images of 70 patients with neuroepithelial tumors pathologically proven were collected and analyzed restrospectively. All the patients were classified into low(WHOⅠ or Ⅱ)and high(WHO Ⅲ or Ⅳ)grade groups which included 40 and 30 cases respectively accroding to the 2007 WHO classification of tumours of the central nervous system. All the patients underwent plain and contrast-enhanced MR scan and DWI before surgery. The minimum ADC(MinADC)value was measured postoperatively on ADC maps. The Ki-67 labeling index(Ki-67 LI)of tumor tissue was determined by immunohistochemistry.MinADC values for two groups were analyzed using student t test, while the age and Ki-67 LI for the two groups was analyzed using Mann-Whitney test(P<0.05 considered to be significant=.Also the MinADC valHe and Ki-67 LI were analyzed with Pearson correlation. The receiver operating characteristic analysis was used for evaluation for grading neuroepithelial tumors of the patients using MinADC. Results The mean MinADC value[(1.08±0.31)×10~(-3) mm~2/s]of the low grade group was significantly higher than that[(0.74±0.18)×10~(-3) mm~2/s]of the high grade group(t=5.42,P<0.05=,and the Ki-67 LI of the low grade group[0-50%,median 4%]was significantly lower than that[0-75%,median 25%]of the high grade group(U=325.50,P<0.05=.There was a negative correlation between MinADC value and Ki-67 LI(r=-0.30,P<0.05=.The area under the ROC curve was 0.85,and the cutoff MinADC value of 0.86×10~(-3) mm~2/s for the differentiation between high and low grade neuroepithelial tumors provided the best combination of sensitivity(90.0%)and specificity(77.5%)(receiver operatingcharacteristic analysis).Conclusion MinADC value is helpful for prediction of neuroepithelial tumor grade.
