RESUMEN
<p><b>OBJECTIVE</b>To study the effects of "XUE BI JING plus LIANQIAO" injection on gene expression levels of rats with sepsis model.</p><p><b>METHODS</b>One hundred and twenty rats were randomly divided into sham operation group, sepsis model group, Te-neng group and "XUE BI JING plus forsythia suspension" group. The sepsis model of rats was prepared by "CLP" method. Tai neng group was treated by peritoneal injection Imipenem/ Cilastatin (0.18 g/kg); "XUE BI JING plus LIANQIAO" group was treated by peritoneal injection Imipenem/ Cilastatin (0.18 g/kg) plus "xue-bi-jing" (10 ml/kg) and "liang ge san" (18 g/200 g) by intragastric administration 2 times a day; the sham operation group and model group were treated by peritoneal injection of normal saline (10 ml/kg). The survival rates at 48h and 72h were observed for all groups. The gene expression levels of livers in all groups were detected by BiostarR-40s chip. The NCBI database was used to inquest Gene function and class.</p><p><b>RESULTS</b>The survival rates at 48h and 72h in "XUE BI JING+ forsythia suspension" group were 83.3% and 76.7% which were significantly higher than those (30.0% and 16.7%) in sepsis model group and those (60.0% and 33.3%) in Te-neng group (P < 0.01). Model group/control group have 305 differential expression genes with 159 up-regulation genes and 146 down-regulation genes. Tai-neng group/model group have 386 differential expression genes with 206 up-regulation genes and 180 down-regulation genes. "XUE BI JING plus forsythia suspension" group/model group have 342 differential expression genes with 102 up-regulation genes and 240 downregulation genes. The genes with up-regulation in model group/ control group and with down-regulation in"XUE BI JING plus forsythia suspension" group/model group were 24. The genes with down-regulation in the model group/ sham operation group and with up-regulation in "XUE BI JING plus forsythia suspension"group/model group were 16.</p><p><b>CONCLUSION</b>"XUE BI JING plus forsythia suspension" can reduce the mortality of rats with sepsis, which could be due to the expression of relative regulation genes.</p>
