Analyzing Active Constituents and Optimal Steaming Conditions Related to the Hematopoietic Effect of Steamed Panax notoginseng by Network Pharmacology Coupled with Response Surface Methodology.
During hundreds of years of medication, it is believed that the steamed Panax notoginseng (SPN) can enrich and regulate the blood, replenish the body, and improve the health. The aim of this study was to optimize the steaming conditions of SPN which are related to the hematopoietic effect. In the study, network pharmacology and pharmacological experiments were used to predict and verify the potential hematopoietic active ingredients of SPN. Three variables including the steaming time (2-10 h), steaming temperature (90-130°C), and different producing areas of PN were investigated by using single-factor analysis. Box-Behnken design response surface methodology (BBD-RSM) was performed to explore the optimized steaming conditions which are responsible for the hematopoietic effect of SPN. Furthermore, the hematopoietic effect of the optimized SPN was evaluated. Results demonstrated that ginsenoside Rd, Rh1, Rh4, Rk3, and 20(S)-Rg3 can significantly increase blood routine parameters and expressions of hematopoietic factors in anemia mice. The total contents of the five ginsenosides were selected as evaluation indexes of the response surface method. We found that the PN from Wenshan steamed at 120°C for 5 h could significantly increase the levels of blood routine parameters and hematopoietic factor expression compared with the model group. The study not only provides data support for the determination of hematinic effect-related markers for SPN but also gives a scientific reference for the processing of SPN which has a better hematopoietic effect. The underlying mechanisms require further research.

Homotherapy for heteropathy of Alzheimer's disease and anemia through reducing the expression of toll-like receptor and TNF by steamed Panax notoginseng.
One of the effects of Steamed Panax notoginsen (SPN) is to replenish blood, which is mostly used to treat anemia in clinic. SPN has the effect of treating anemia and Alzheimer's disease (AD) in clinical and basic research. In traditional Chinese medicine, anemia and AD have the same characteristics, and their symptoms are qi and blood deficiency.
First, data analysis was carried out through network pharmacology to predict the action targets of SPN homotherapy in the treatment of AD and anemia. Specifically, TCMSP and relevant literature were used to screen the main active ingredients of Panax notoginseng, and SuperPred was used to predict the action targets of the active ingredients. Disease targets related to AD and anemia were collected through Genecards database, and STRING and protein interaction (PPI) was used for enrichment analysis, Analyze the characteristics of the active ingredient target network on the Cytascape 3.9.0 platform, and use Metascape to enrich the gene ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes Pathway Enrichment (KEGG pathway). Then Drosophila was used as the AD animal model, and the effects of SPN on the climbing ability, olfactory memory and brain Aβ, with rats as anemia animal models, the improvement effect of SPN on blood routine and organ index of rats with blood deficiency induced by CTX and APH was analyzed to further explain the therapeutic effect of SPN on these two diseases. Finally, the regulatory effect of SPN on the key active target of allotherapy for AD and anemia was verified by PCR.
After the screening, 17 active components and 92 action targets of SPN were obtained. The degree values of components and the first 15 targets are NFKB1, IL10, PIK3CA, PTGS2, SRC, ECFR, CASP3, MTOR, IL1B, ESR1, AKT1, HSP90AA1, IL6, TNF, and Toll-like receptor, it is mainly related to inflammatory response, immune regulation and antioxidation. SPN improved the climbing ability, olfactory memory ability, and Aβ42 content in the brain of Aβ flies, and significantly reduced the expression of TNF and Toll-like receptor in the brain after treatment. SPN can significantly improve the blood routine index and organ index of anemia rats, and also significantly reduce the expression of TNF and Toll-like receptor in the brain after treatment.
SPN can regulate the expression of TNF and Toll-like receptor to achieve the same treatment of AD and anemia.

Steamed Panax notoginseng attenuates renal anemia in an adenine-induced mouse model of chronic kidney disease.
Panax notoginseng (PN) (Burk.) F. H. Chen is a medicinal herb used to treat blood disorders since ancient times, of which the steamed form exhibits the anti-anemia effect and acts with a "blood-tonifying" function according to the traditional use. However, its pharmacological effect and mechanism on alleviating renal anemia (RA) are still unclear.
The study aims to investigate the effect of steamed Panax notoginseng (SPN) to attenuate RA and its underlying mechanism based on the model of adenine-induced RA mice.
Seventy mice were randomly divided into seven groups of ten: the control group, model group, the erythropoietin (EPO) group, the Fufang E'jiao Jiang (FEJ) group, the high-dose steamed PN (H-SPN) group, the middle-dose steamed PN (M-SPN) group, and the low-dose steamed PN (L-SPN) group. The adenine induction RA model was applied to assess the "blood enriching" function of SPN. The blood routine indexes, erythrocyte fragility, pathologic morphology of kidney tissue and the expression levels of related cytokines and proteins in the mice were detected after 3-week administration with SPN and positive drugs.
Our study provided evidences that SPN could ameliorate RA. Compared with the control group, SPN could attenuate RA by significantly increasing the numbers of peripheral blood cells (p < 0.01), improving the erythrocyte fragility (p < 0.01), and restoring the expression of EPO mRNA in the kidneys and EPO receptor mRNA in bone marrow nucleated cells. The expression of TGF-β1 mRNA was declined and the expression of HGF mRNA was significantly increased in a dose-dependent way after the treatment of SPN. Additionally, the expression of Bcl-2 and Bcl-2/Bax ratio in the kidneys were significantly increased. In contrast, there was a highly significant decrease in the expression of Bax (p < 0.01), following SPN treatment.
SPN could alleviate RA by promoting the overall hematopoiesis and inhibiting the progress of renal injury in mice.

Steamed Panax notoginseng Attenuates Anemia in Mice With Blood Deficiency Syndrome via Regulating Hematopoietic Factors and JAK-STAT Pathway.
Panax notoginseng (Burk.) F. H. Chen is a medicinal herb used to treat blood disorders since ancient times, of which the steamed form exhibits the anti-anemia effect and acts with a "blood-tonifying" function according to traditional use. The present study aimed to investigate the anti-anemia effect and underlying mechanism of steamed P. notoginseng (SPN) on mice with blood deficiency syndrome induced by chemotherapy. Blood deficiency syndrome was induced in mice by cyclophosphamide and acetylphenylhydrazine. A number of peripheral blood cells and organs (liver, kidney, and spleen) coefficients were measured. The mRNA expression of hematopoietic function-related cytokines in the bone marrow of mice was detected by RT-qPCR. The janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway was screened based on our previous analysis by network pharmacology. The expression of related proteins and cell cycle factors predicted in the pathway was determined by Western blot and RT-qPCR. SPN could significantly increase the numbers of peripheral blood cells and reverse the enlargement of spleen in a dose-dependent manner. The quantities of related hematopoietic factors in bone marrow were also increased significantly after SPN administration. SPN was involved in the cell cycle reaction and activation of immune cells through the JAK-STAT pathway, which could promote the hematopoiesis.
