ABSTRACT
OBJECTIVE To observe the influence of XueBiJing on apoptosis,apoptosis-associated proteins and activity of caspase 3 in spleen of sepsis rats.METHODS The sepsis models were produced by cecal ligation and puncture(CLP).Ninety-six Wistar rats were randomly divided into four groupscontrol group(n=8),sham operation group(n=8),model group(n=40),and XueBiJing treatment group(n=40).TUNEL method was used to assess the apoptosis,the activity of caspase 3 and the percent of CD3+ lymphocyte in spleen were tested,and the expressions of FasL and Bcl-2 in spleen were detected by immunohistochemistry methods.RESULTS The integrated optic density(IOD) of FasL expression in spleen for sham operation group was 4.54?1.41,but in model group was much higher(757.96?188.10 at 48 h) and the IOD of Bcl-2 in sham operation group was 594.05?183.32,but in model group was only 22.71?9.22 at 48 h.There were a few apoptosis appeared in sham operation group(0.87?0.51),the activity of caspase 3 was low(4.34?1.34),and the percent of CD3+ lymphocyte in spleen was 63.49%.At 4 h after the CLP operation,there were more apoptosis appeared in model group(8.88?3.68),the activity of caspase 3 reached to 12.22?3.15,and the percent of CD3+ lymphocyte in spleen decreased to 52.09%.After the intervention of XueBiJing,the expression of FasL reduced and Bax raised.The intervention also lightened the activity of caspase 3 and the apoptosis,and made the percent of CD3+ lymphocyte returned to normal level.CONCLUSIONS The activation of apoptosis pathway makes the apoptosis over-appeared,also induces the immune system out-of-balance.The intervention of XueBiJing can ameliorate the immune paralysis of sepsis by regulating the expression of apoptosis-associated proteins and lighten the apoptosis of lymphocyte.
