To study the effectof Sanqi（Notoginseng Radix et Rhizoma）onmitochondrial energy metabolism of rats with adriamycin induced kidney fibrosis with blood stasis.

Thirty rats were divided into 6 groups random ly，including normal group，model group，Sanqi（Notoginseng Radix et Rhizoma）low-dose group，Sanqi（Notoginseng Radix et Rhizoma）medium-dose group，Sanqi（Notoginseng Radix et Rhizoma）high-dose group and positive control group，with 5 rats in each group.Themitochondrial structure of rat renal tissue was observed by electron microscopy.The contents of adenosine triphosphate（ATP），adenosine diphosphate（ADP），adenosine monophosphate（AMP），the activities of Na⁺ -K⁺ -ATPase，Ca²⁺ -Mg²⁺-ATPase and the activities ofmitochondrial respiratory chain complex enzymeⅠ-Ⅳwere detected by chemical method.The metabolites of urine were analyzed by liquid chromatograph and mass spectrometer.The differential metabolites were enriched by Kyoto Encyclopedia of Genes and Genomes（KEGG）metabolic pathway.

Under electron microscope，the mitochondrial structure of renal tissue in the model group was incomplete，and Sanqi（Notoginseng Radix et Rhizoma）could maintain the homeostasis of renalmitochondrial structure.Sanqi（Notoginseng Radix et Rhizoma）could increase the mitochondrial ATP contentof the renal tissue，the activities of Na⁺-K⁺-ATPase，Ca²⁺-Mg²⁺-ATPase andmitochondrial respiratory chain complex enzymeⅠ-Ⅳ.Sanqi（Notoginseng Radix et Rhizoma）could reduce the contents of mitochondrial ADP and AMP of renal tissue.After analysis and comparison among the groups，11 different urine metabolites were screened，including ferulic acid，forin，arabitol，acetamide，biotin，allantoic acid，6-methylmercaptopurine，4-hydroxy-2-quinolone，aminopentanedioate，6-methyladenine and moupinamide.Further enrichment of urinemetabolites by KEGG in different experimental groups showed that the aldosterone-regulated sodium reabsorption signal pathway was significantly different.

Sanqi（Notoginseng Radix et Rhizoma）regulates the differential urine metabolites and raldosterone-regulated sodium reabsorption signal pathway.Sanqi（Notoginseng Radix et Rhizoma）can improve mitochondrial energy metabolism and renal fibrosis in chronic kidney diseases（CKD）rats with blood stasis bymulti-target and multi-pathway.
