Abstract
Background Type 2 diabetes mellitus (T2DM) is a metabolic disease. Simiao Wan (SMW) is a commonly used clinical drug for hyperuricemia treatment. SMW has been confirmed to improve insulin resistance and is expected to be a novel hypoglycemic agent. However, the hypoglycemic bioactive ingredients and mechanisms of action of SMW are unclear. Objective To explore the hypoglycemic effects and reveal the mechanisms of SMW and bioactive ingredients (SMW-BI). Study design and methods The hypoglycemic effects of SMW and SMW-BI were verified in a mouse model of T2DM induced by streptozotocin (STZ) and a high-fat and high-sugar diet (HFSD). Network pharmacology was used to predict the mechanisms of SMW and SMW-BI. Histological analysis and real-time quantitative polymerase chain reaction (RT-qPCR) verified network pharmacology results. RT-qPCR results were further verified by immunofluorescence (IFC) and molecular docking. The correlation between proteins and biochemical indicators was analyzed by Spearman's correlation. Results Chlorogenic acid, phellodendrine, magnoflorine, jateorhizine, palmatine, berberine, and atractydin were identified as SMW-BI. After 8 weeks of treatment, SMW and SMW-BI decreased the levels of fasting blood glucose (FBG), total cholesterol (TC), triacylglycerols (TG) and low-density lipoprotein cholesterol (LDL-C), increased the level of high-density lipoprotein cholesterol (HDL-C), alleviated weight loss, and increased serum insulin levels in T2DM mice. In addition, SMW and SMW-BI improved hepatocyte morphology in T2DM mice, decreased the number of adipocytes, and increased liver glycogen. Network pharmacological analysis indicated that SMW and SMW-BI may exert hypoglycemic by regulating insulin receptor substrate 1 (IRS1)/RAC-beta serine/threonine-protein kinase (AKT2)/forkhead box protein O1 (FOXO1)/glucose transporter type 2 (GLUT2) signaling. Moreover, correlation analysis showed that SMW and SMW-BI were associated with activation of IRS1, AKT2, and GLUT2, and inhibiting FOXO1. RT-qPCR revealed that SMW and SMW-BI could increase levels of IRS1, AKT2, and GLUT2 in the livers of T2DM mice and lower the level of FOXO1. Furthermore, immunofluorescence analysis showed that FOXO1 expression in the livers of T2DM mice decreased after oral administration of SMW and SMW-BI. Furthermore, molecular docking showed that SMW-BI could bind directly to IRS1 and AKT2. Conclusion SMW and SMW-BI are potential hypoglycemic drugs that alleviate T2DM by regulating IRS1/AKT2/FOXO1 signaling. Our study provides a research idea for screening the bioactive ingredients in traditional Chinese medicine (TCM).

Abstract
BACKGROUND Gut microbiota coupled with their metabolites (bile acids, BAs) get involved in diabetic pathogenesis. Simiao Wan is a famous traditional Chinese formula consisting on Phellodendron chinense C.K.Schneid. (Rutaceae), Atractylodes lancea (Thunb.) DC. (Asteraceae), Achyranthes bidentata Blume (Amaranthaceae) and Coix lacryma-jobi var. ma-yuen (Rom.Caill.) Stapf (Poaceae), and used to treat gouty arthritis and hyperuricemia for thousands of years. However, the mechanisms underlying its beneficial efficacy on diabetes still needs to be explored. PURPOSE Our study was performed to reveal the effects of the 75% ethanol extraction of Simiao Wan (SMW) on diabetes, gut microbiota and bile acids (BAs) in diabetic mice. METHODS The effects of SMW on diabetes were evaluated in mice treated by high-fat diet (HFD)/streptozotocin (STZ). The 16S rDNA sequencing and BAs metabolomics were performed to assess the changes of BAs profiles and gut microbiota induced by SMW. Western blot and real-time quantitative PCR were conducted to evaluate the possible mechanism of SMW. RESULTS SMW significantly improved insulin resistance and hepatic lipid accumulation in HFD/STZ mice. It remarkably enriched in the bacteria Allobaculum, Clostridium, Akkermansia, Lactobacilus and Bilophila whereas decreased Coprococcus and Halomonas in diabetic mice. Furthermore, the profiles of BAs were also modulated by SMW, indicated by the reduction of conjugated BAs and 12α-OH/non-12α-OH BAs ratio in liver as well as the increase of primary BAs in feces. SMW also activated farnesoid X receptor and inhibited sterol regulatory element-binding protein-1 expression, contributing to its beneficial actions on lipid accumulation in liver. CONCLUSION Our results showed that SMW exerted its beneficial effects on insulin resistance and hepatic lipid accumulation indirectly through regulating profiles of gut microbe and BAs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Simiao Wan (SMW) is a classical traditional Chinese medicine (TCM) prescription to empirically treat gouty arthritis (GA) in TCM clinical practice. However, the potential mechanisms of SMW on GA are not fully evaluated. AIM OF STUDY The aim of this study is to investigate the role of macrophage polarization in the anti-GA activity of SMW. MATERIALS AND METHODS Rats were intragastricly treated with SMW for consecutive 7 days. On day 6, monosodium urate (MSU) crystal-induced arthritis (MIA) in the ankle joint was prepared. Paw volume, gait score and histological score were measured. Levels of interleukin (IL)-1β and IL-10 in serum were detected by enzyme-linked immunosorbent assay. Expressions of inducible nitric oxide synthase (iNOS), arginase (Arg)-1, phosphorylated (p)-p65, inhibitor of nuclear factor (NF)-κB (IκB)α, p-signal transducer and transcription activator (STAT)3 and p-Janus kinase (JAK)2 in synovial tissues were determined by Western blot. RESULTS The elevated paw volume, gait score and histological score in MIA rats were significantly decreased by SMW treatment. Meanwhile, SMW significantly decreased the IL-1β level and increased the IL-10 level in serum of MIA rats. Furthermore, SMW reduced the expressions of iNOS, p-p65 and enhanced the expressions of Arg-1, IκBα, p-STAT3 and p-JAK2 in synovial tissues of MIA rats. CONCLUSIONS The results suggest that SMW attenuates the inflammation in MIA rats through promoting macrophage M2 polarization.
