    Abstract:
    OBJECTIVE: To explore whether yiqi huoxue tongluo jiedu fang (YHTJF, Traditional Chinese Medicine) alleviates the injury during lung ischemia/reperfusion (I/R) in mice through inhibiting oxidative stress or not. METHODS: C57BL/6J male mice (n=70) were randomly divided into 7 groups:control (C), carboxyl methyl cellulose-Na(CMC·Na) + normal control (CC), carboxyl methyl cellulose-Na + sham (CS), carboxyl methyl cellulose-Na + I/R (CIR), carboxyl methyl cellulose-Na + YHTJF-Low, CMC-Na + YHTJF-Middle, CMC-Na + YHTJF-High (CYL, CYM, CYH). The mice in CYL, CYM and CYH group were treated with YHTJF by intraperitoneal injection every day, while the carboxyl methyl cellulose-Na was administered with the same volume of CYL in CC, CS and CIR group. After 3 h-reperfusion, the left lung tissues were harvested to determine the lung wet/dry weight (W/D), the total lung water content (TLW), and the index of quantita-tive evaluation for alveolar damage (IQA). Morphological observation and terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) were applied to evaluate the structural changes and the apoptosis index (AI) of the lung tissues. The expressions superoxide of dis-mutase(SOD), malondialdehyde(MDA) and myeloperoxidase(MPO) in the lung tissues were detected by kits. RESULTS: Compared with group C, the W/D, TLW, IQA, AI, lung tissue structural changes, and the expressions of MDA and MPO in group I/R were increased obviously (P < 0.01), and the expression of SOD was decreased, while there was no significant difference between group CC and CS. Compared with group I/R, the parameters of these experiments in group CYL, CYM, CYH were all decreased, and the expression of SOD was increased, while the reduction in group CYM was the most remarkable among them (P < 0.01). CONCLUSIONS: YHTJF may attenuate the I/R injury of the lung by the inhibition of apoptosis via ROS pathway.
