Objective To investigate the role of interleukin-17A (IL-17A) in acute paraquat (PQ)-induced lung injury in mice.Methods A total of 120 healthy SPF grade ICR male mice were randomly (random number) divided into three groups (n =40 in each):normal saline control group (NS),PQ poisoning group (PQ) and antibody neutralization group (PQ + Ab).Mice of PQ group and PQ + Ab group were given 5 mg/mL PQ by one gavage in a dosage of 25 mg/kg body weight,and 5 μg IL-17A neutralizing antibody intra-peritoneally administered immediately after PQ poisoning in PQ + Ab group;Equivalent volume of normal saline instead of PQ was given to mice of NS group.Six survival mice from each group were taken for experiment at 8 h,1 d,3 d,5 d,7 d after PQ poisoning:Wet to dry ratio (W/D) of lung was determined in mice of each group.HE staining of lung tissue was used to observe the histopathological changes under the light microscope and the pathological scores were graded;Serum interleukin-17A (IL-17A),interleukin-22 (IL-22),interleukin-6 (IL-6),transforming growth factor-β (TGF-β) were detected with enzyme linked immunosorbent assay (ELISA);Expression of interleukin-23 receptor (IL-23R) in lung tissue was determined with immunohistochemical;real-time fluorescence quantification PCR (qRT-PCR) was used to detect the expression of retinoic acid related solitary nuclear receptors' mRNA in lung tissue.Results After administration of PQ,W/D ratio increased (P ＜ 0.01),lung injury was observed in mice of PQ and PQ + Ab groups,levels of cytokines (IL-17A,IL-22,IL-6 and TGF-β) in serum elevated (P ＜0.05),and the expressions of IL-23R mRNA and RORγt mRNA increased (P＜0.01).But in PQ +Ab group,W/D ratio decreased (P ＜0.05),lung injury was alleviated,the levels of cytokines (IL-17A,IL-22,IL-6 and TGF-β) decreased (P ＜ 0.05),and the expressions of IL-23R mRNA and RORγt mRNA reduced (P ＜ 0.05).Conclusions Since IL-17A involves in the lung injury of the mice induced by acute paraquat poisoning,blockade of IL-17A significantly alleviates the acute lung injury in mice.

Objective: To investigate the intervention of Shiquan Dabu Decoction (SQDBD) in the protein expression of VEGF. Methods: 50 C57BL/6 mice inoculated with lewis lung cancer were randomly divided into five groups and treated by different drugs. The ratio of antitumorand and antimetastatic of each group were calculated after 15 days’ treatment. The expression of VEGF was detected by SABC immunohistochemical method. Results: Low, medium and high dosages of SQDBD had the function of antitumor and antimetastusi at different extent. SQDBD could inhibit the positive expression of VEGF protein. Conclusion: Inhibition of the expression of VEGF protein is possibly one of the mechanisms of SQDBD in antitumor.
