Peripheral arterial disease (PAD) is a typical disease of atherosclerosis, most commonly influencing the lower extremities. In patients with PAD, revascularization remains a preferred treatment strategy. Buyang Huanwu decoction (BHD) is a popular Chinese herbal prescription which has showed effects of cardiovascular protection through conducting antioxidant, antiapoptotic, and anti\u2010inflammatory effects. Here, we intend to study the effect of BHD on promoting revascularization via the Akt\/GSK3<jats:italic>\u03b2<\/jats:italic>\/NRF2 pathway in diabetic hindlimb ischemia (HLI) model of mice. <jats:italic>Materials and Methods<\/jats:italic>. All db\/db mice (<jats:italic>n<\/jats:italic> = 60) were randomly divided into 6 groups by table of random number. (1) Sham group (<jats:italic>N<\/jats:italic> = 10): 7\u20100 suture thread passed through the underneath of the femoral artery and vein without occlusion. The remaining 5 groups were treated differently on the basis of the HLI (the femoral artery and vein from the inguinal ligament to the knee joint were transected and the vascular stump was ligated with 7\u20100 silk sutures) model: (2) HLI+NS group (<jats:italic>N<\/jats:italic> = 15): 0.2\u2009ml NS was gavaged daily for 3 days before modeling and 14 days after occlusion; (3) HLI+BHD group (<jats:italic>N<\/jats:italic> = 15): 0.2\u2009ml BHD (20\u2009g\/kg\/day) was gavaged daily for 3 days before modeling and 14 days after occlusion; (4) HLI+BHD+sh\u2010NC group (<jats:italic>N<\/jats:italic> = 8): local injection of adenovirus vector carrying the nonsense shRNA (Ad\u2010GFP) in the hindlimbs of mice before treatment; (5) HLI+BHD+sh\u2010NRF2 group (<jats:italic>N<\/jats:italic> = 8): knockdown of NRF2 in the hindlimbs of mice by local intramuscular injection of adenovirus vector carrying NRF2 shRNA (Ad\u2010NRF2\u2010shRNA) before treatment; and (6) HLI+BHD+LY294002 group (<jats:italic>N<\/jats:italic> = 4): intravenous injection of LY294002 (1.5\u2009mg\/kg) once a day for 14 days on the basis of the HLI+BHD group. Laser Doppler examination, vascular cast, and immunofluorescence staining were applied to detect the revascularization of lower limbs in mice. Western blot analysis was used to detect the expression of vascular endothelial growth factor (VEGF), interleukin\u20101beta (IL\u20101<jats:italic>\u03b2<\/jats:italic>), interleukin\u20106 (IL\u20106), tumor necrosis factor\u2010 (TNF\u2010) <jats:italic>\u03b1<\/jats:italic>, heme oxygenase\u20101 (HO\u20101), NAD(P)H dehydrogenase quinone\u20101 (NQO\u20101), catalase (CAT), glyceraldehyde\u20103\u2010phosphate dehydrogenase (GAPDH), phosphorylated protein kinase B (p\u2010AKT), and phosphorylated glycogen synthase kinase\u20103 beta (p\u2010GSK3<jats:italic>\u03b2<\/jats:italic>). HE staining was used to assess the level of muscle tissue damage and inflammation in the lower extremities. Local multipoint injection of Ad\u2010NRF2\u2010shRNA was used to knock down NRF2, and qPCR was applied to detect the mRNA level of NRF2. The blood glucose, triglyceride, cholesterol, MDA, and SOD levels of mice were tested using corresponding kits. The SPSS 20.0 software and GraphPad Prism 6.05 were used to do all statistics. Values of <jats:italic>P<\/jats:italic> &lt; 0.05 were considered as statistically significant. <jats:italic>Results and Conclusions<\/jats:italic>. BHD could enhance the revascularization of lower limbs in HLI mice, while BHD has no effect on blood glucose and lipid level in db\/db mice (<jats:italic>P<\/jats:italic> &gt; 0.05). BHD could elevate the protein expression of VEGF, HO\u20101, NQO\u20101, and CAT (<jats:italic>P<\/jats:italic> &lt; 0.05) and decrease the expression of IL\u20101<jats:italic>\u03b2<\/jats:italic>, IL\u20106, and TNF\u2010<jats:italic>\u03b1<\/jats:italic> (<jats:italic>P<\/jats:italic> &lt; 0.05) in HLI mice. Meanwhile, BHD could activate NRF2 and promote the phosphorylation of AKT\/GSK3<jats:italic>\u03b2<\/jats:italic> during revascularization (<jats:italic>P<\/jats:italic> &lt; 0.05). In contrast, knockdown of NRF2 impaired the protective effects of BHD on HLI (<jats:italic>P<\/jats:italic> &lt; 0.05). LY294002 inhibited the upregulation of NRF2 activated by BHD through inhibiting the phosphorylation of the AKT\/GSK3<jats:italic>\u03b2<\/jats:italic> pathway (<jats:italic>P<\/jats:italic> &lt; 0.05). The present study demonstrated that BHD could promote revascularization on db\/db mice with HLI through targeting antioxidation, anti\u2010inflammation, and angiogenesis via the AKT\/GSK3<jats:italic>\u03b2<\/jats:italic>\/NRF2 pathway.<\/jats:p>","DOI":"10.1155\/2021\/1470829","type":"journal-article","created":{"date-parts":[[2021,12,3]],"date-time":"2021-12-03T20:05:05Z","timestamp":1638561905000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Buyang
