ABSTRACT

In this paper, Asarum polysaccharides(AP) were extracted, and its composition was analyzed to study the activity against H1 N1 influenza virus in vitro and its intervention effect on mice with kidney Yang deficiency syndrome. AP was prepared by the strategy of water extraction and alcohol precipitation, the content was determined, and its monosaccharide composition was analyzed. The cell Real-time monitoring system and Reed-Muench model were adopted to evaluate the antiviral activity of AP in vitro. And the mouse model of kidney Yang deficiency syndrome was established in vivo to compare the efficacy of Mahuang Xixin Fuzi Decoction(MXF) and AP. MXF group and AP group were treated with clinical equivalent doses of 1.8 g·kg~(-1)·d~(-1) and 0.077 g·kg~(-1)·d~(-1) respectively, once a day for 6 consecutive days. Real-time PCR was used to detect the relative expression of M gene of H1 N1 influenza virus and cytokines in lung tissue. The content of AP in Asarum was 25.22%, and the protein content was 0.8%. And the monosaccharide composition was identified as L-rhamnose, D-arabinose, D-xylose, D-glucose, D-galactose and D-mannose. TI values of Tamiflu, MXF and AP were 30.00, 8.06 and 10.33, respectively. Three different doses of AP could significantly reduce the concentration of virus in supernatant. Compared with the model mice, lung indexes of MXF group and AP group decreased significantly(P<0.05), and the relative expression of M gene decreased significantly(P<0.05). The relative expressions of IL-10 and IFN-γ were up-regulated to varying degrees, while the relative gene expressions of IL-1β, IL-6 and MCP-1 were down-regulated to different degrees. In addition, AP could significantly enhance the expression of TNF-α(P<0.01). AP had a good anti-influenza virus activity in vitro, and could protect mice with kidney Yang deficiency syndrome by reducing the viral load in lung tissue, decreasing inflammation damage in lung tissue, and regulating the expression of inflammatory cytokines. Compared with the prescription of MXF, AP had a better antiviral activity.

ABSTRACT

The rat osteoarthritis model was replicated by injection of sodium iodoacetate into the knee joint cavity, and the effects of Gancao Fuzi Decoction on rat osteoarthritis and the proteome of articular cartilage were investigated. Sixty SD rats weighing 230-250 g were randomly divided into normal group, model group, glucosamine sulfate group, and Gancao Fuzi Decoction high, medium and low dose groups. Osteoarthritis model was induced by intra-articular injection of sodium iodoacetate(3 mg on each leg) in all groups except the normal group. After modeling, each administration group was given intragastric administration for 1 month. During the administration period, joint pain test and joint width measurement were performed every week to observe the autonomous behavior of rats. Enzyme linked immunosorbent assay(ELISA) method was used to detect the contents of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), matrix metalloproteinase-3(MMP-3), and matrix metalloproteinase tissue inhibitor(TIMP-1) in rat joint lavage fluid. Hematoxylin-eosin(HE) staining was used to observe bone and joint morphology. Nano-LC-LTQ-Orbitrap system was used to detect arti-cular cartilage proteins. The results showed that, compared with the model group, Gancao Fuzi Decoction could significantly improve joint pain and joint swelling in osteoarthritis rats, significantly reduce the contents of TNF-α, IL-1β and MMP-3 in the joint cavity la-vage fluid, increase the content of TIMP-1, and relieve inflammatory diseases such as enlarged joint space, rough cartilage edge, different thickness of cartilage layer, and disordered arrangement of chondrocytes. After comparing the proteins between the groups, 273 differential proteins were screened out. KEGG analysis found that the above differential proteins involved 43 signaling pathways such as systemic lupus erythematosus, among which 11 signaling pathways were related to osteoarthritis. The above results indicated that Gancao Fuzi Decoction had a preventive effect on osteoarthritis, and its mechanism of action may be accomplished by regulating the protein expression of osteoarthritis-related signal pathways.

ABSTRACT

OBJECTIVE: To study the pharmacodynamic effects of Mahuang Xixin Fuzi Decoction (MXF) on mice with kidney-yang deficiency, its toxic effects on normal mice and effect-toxic mechanism. METHODS: BABL/C male mice were randomly divided into normal groups; normal groups with low, medium and high toxicity; kidney Yang deficiency model group. The low, medium and high dose groups were treated with infected Influenza virus of kidney-yang deficiency. After continuous gavage for 6 days, the body weight anal temperature and other pharmacological indicators were recorded, and the general signs, biochemical indicators and inflammatory factors of the mice were detected. RESULTS: Compared with the normal group, the biochemical parameters of the kidney yang deficiency model group, which means the creatine kinase (CK), creatine kinase-isoenzyme (CK-MB), alpha-hydroxybutyrate dehydrogenase (α-HBDH), lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP) and urea (urea) were significantly increased (P<0.05), inflammatory factors interleukin-6 (IL-6), monocyte deproteinization protein (MCP-1), tumor necrosis factor-α (TNF-α), interleukin-10 (IL- 10), interferon-γ (INF-γ) and interleukin 12 (IL-12p70) increased significantly (P<0.05). After administration, the levels of biochemical markers such as CK, ALT and urea in each administration groups were slightly reduced compared with the model group. The levels of inflammatory factors such as IL-6, IL-10 and IFN-γ in each administration groups showed different degrees of callback compared with the model group. In the toxicity study, the biochemical indicators of CK, urea, and cysteine (CYS-C) in each drug-administered group were significantly higher than those in the normal group (P<0.05), and the inflammatory factor interleukin-10 (IL-10) increased significantly, and the content of interleukin-12 (IL-12p70) decreased significantly (P<0.05). CONCLUSION: After treatment with MXF, the above biochemical indicators of mice with kidney yang deficiency and external sensation have different degrees of callback. MXF can achieve therapeutic effects by regulating IL-6, IL-10, IFN-γ, MCP-1, TNF-α and other factors on the body′s inflammatory response. While normal mice give different doses of MXF, the heart, liver and kidney function are dysfunctional, the balance of immune response of the body are broken through cell transfer, thus making normal mouse developed an inflammatory response.

ABSTRACT

Network pharmacology and bioinformatics technology were used to predict the mechanism of action of Fuzi-Lizhong pill (FLP) in the treatment of ulcerative colitis (UC). 26 components (23 prototype compounds and 3 metabolites) in the blood of FLP were selected as the research objects. PharmMapper database, SwissTargetPrediction platform, GeneCards and OMIM database were used to screen and predict potential targets of FLP in blood. The protein-protein interaction network model was constructed by using String database and Cytoscape software. DAVID platform, KEGG and Reactome databases were used for GO analysis and pathway analysis of potential targets. Network of drug ingredients-targets-pathways was constructed by Cytoscape software. AutoDock vina software was used to dock the molecules of the absorbed ingredients of FLP in blood with the key targets. 82 potential targets of FLP for treatment of UC were obtained. Potential targets mainly involve biological processes such as response to organic substance, regulation of apoptosis, regulation of programmed cell death, which played roles in the treatment of UC by adjusting pathways in cancer, Colorectal cancer, Vascular endothelial growth factor signaling pathway, Mitogen-activated protein kinase signaling pathway, arachidonic acid metabolism and the other signal pathways. From the perspective of network pharmacology, this study predicted the mechanisms of action of FLP in treating UC, indicating that FLP in treating UC had the characteristics of multiple ingredients, multiple targets and multiple pathways, which laid a foundation for further research.

ABSTRACT

As a most important Chinese materia medica, Aconiti Lateralis Radix Praeparata(Fuzi) had been widely used in China for thousands of years. This herbalogical study was systematically performed based on variation characteristics of the naming, habitat, harvesting, processing and properties. The sharp toxicity of Fuzi had been well known since the spring and autumn period in the history, which was much earlier than that its medical properties was understood and applied. Sichuan province was regarded as the geo-authentic region of Fuzi all along, where the best quality goods could be provided for clinic use. The study showed the harvesting time of Fuzi was changing in different periods, and the possible effects were of climate change and artificial planting. The perishable characteris-tics of Fuzi severely limited its storage period; therefore, different kinds of storage methods were effectively used since Tang Dynasty. For thousands of years, Fuzi had been processed with various accessories to reduce toxicity, while simultaneously the study on processing mechanism was on going all the time. Fuzi was widely used in clinical practice to cure Yang depletion syndrome, which was based on its function of enhancing Yang and removing cold. Along with the further study on quality evaluation standard, Fuzi will probably get a much wider range of applications.

ABSTRACT

Objectives:To investigate the therapeutic effect and mechanism of modified Fuzi Lizhongtang on ulcerative colitis (UC) model rats. Method:The 72 male SD rats were randomly divided into normal group,model group,sulfasalazine group(0.5 g·kg-1),modified Fuzi Lizhongtang high,medium and low-dose group (23.62,11.81,5.91 g·kg-1). These rats were used to replicate the UC rat model by 2,4,6-trinitrobenzene sulfonic acid (TNBS)-ethanol composite modeling and treated by gavage for 2 weeks. The general condition of rats in each group was observed. After anesthesia,blood was collected from abdominal aorta and colonic tissue was taken. Semi quantitative evaluation by the colon mucosa damage index (CMDI),the pathological changes of colonic tissue were observed by the hematoxylin and eosin (HE) staining. The contents of serum interleukin-4 (IL-4),IL-6,IL-10 and tumor necrosis factor-α (TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA). The expressions of mammalian target of rapamycin(mTOR) and phosphorylated ribosomal protein S6 kinase 1 (p-S6K1) in colonic mucosa were detected by immunohistochemistry (IHC) and Western blot. Result:Compared with normal group,the CMDI score of the model group rats was significantly increased (P<0.01). The contents of IL-4 and IL-10 in serum were significantly decreased,the contents of IL-6 and TNF-α were significantly increased (P<0.01). The expression levels of mTOR and p-S6K1 in colonic mucosa were up-regulated (P<0.01). Compared with model group,the CMDI score of the modified Fuzi Lizhongtang high dose group was significantly decreased (P<0.05). In modified Fuzi Lizhongtang high and medium dose group,the contents of IL-6 and TNF-α were significantly decreased (P<0.01) and the contents of IL-4 and IL-10 in serum were significantly increased (P<0.05,P<0.01). In the modified Fuzi Lizhongtang high dose group,the expression level of mTOR and p-S6K1 protein was down-regulated significantly (P<0.05,P<0.01). Conclusion:Modified Fuzi Lizhongtang high dose group can significantly reduce the congestion and edema,inflammatory cell infiltration,gland distortion,disorder of arrangement and other pathological manifestations of UC colon mucosa,and its mechanism may be related to its down-regulation of mTOR/p-S6K1 signal and the regulation of inflammatory factors secretion.

ABSTRACT

@#【Objective】The aim of this study is to investigate whether Fuzi polysaccharide(FPS)inhibits calcification of vascular smooth muscle cells(VSMC)and its underlying mechanism involving ceramide signaling.【Methods】We used Ox- LDL to induce in vitro model of human VSMC calcification in this study. FPS at different concentrations was used to treat human VSMC. Cell calcification was assessed by alizarin red staining. The mRNA expressions of osteogenic differentiation markers including Msx2,Osterix and BMP2,and contractile marker SMA were analyzed by qRT- PCR. The protein expressions of Msx2 and BMP2 were analyzed by western blot. Cell apoptosis was examined by TUNEL. Additionally,we investigated the effect of FPS on ceramide levels and N- SMase activity in VSMC. 【Results】We found that FPS inhibits Ox- LDL- induced VSMC apoptosis and calcification. Ceramide participates in Ox- LDL- induced apoptosis and calcification of VSMC. FPS reduces N- SMase activity and ceramide levels in Ox- LDL- treated VSMC. Collectively , reducing N-SMase activity and ceramide levels could become a promising strategy for the treatment of vascular calcification.【Conclusion】We demonstrate that FPS attenuates VSMC calcification via targeting ceramide signaling.

ABSTRACT

Objective:Based on the previous studies, to investigate the dissolution behavior of Fuzi Lizhongwan by simultaneously determining the dissolution of benzoylmesaconine, benzoylaconine and benzoylhypaconine in Aconiti Lateralis Radix Praeparata. Method:The simultaneous determination of benzoylmesaconine, benzoylaconine and benzoylhypaconine in Fuzi Lizhongwan was established by HPLC-QQQ-MS. The dissolution amounts of three compositions in 15 batches of Fuzi Lizhongwan from 5 manufacturers at different time points, the cumulative dissolution was calculated and the dissolution curve was drawn. The f2 similarity factor method was adopted to evaluate similarity of dissolution curves of index components in different batches of samples from the same manufacturer, and to evaluate similarity of dissolution curves of samples from different manufacturers based on the same index component. The dissolution model of Fuzi Lizhongwan was concluded by fitting with the dissolution data. Result:When hydrochloric acid solution with pH of 1.2 was used as the dissolution medium, the three alkaloids had the best dissolution effect. The dissolution behavior of three monoester alkaloids in Fuzi Lizhongwan was basically synchronous and the dissolution lasted for 24 h. Three batches of samples from the same manufacturer (manufacturer 1, 3, 4 and 5) appeared to be similar on dissolution behavior, indicating that the dissolution behavior of the majority of samples from different manufacturers was similar. The dissolution behavior of batch 1 sample was different from batch 2 and 3 samples in manufacturer 2, suggesting that the quality of different batches of samples in manufacturer 2 might be different. The fitting results of dissolution data of index components in samples from different manufacturers were consistent, and the Weibull model was the best. Conclusion:Index components in fifteen batches of samples from 5 manufacturers are continuously dissolved within 24 h, indicating that the samples have the characteristics of slow dissolution. The dissolution curves of samples from the same manufacturer are similar to each other, indicating that the quality of different batches of products from most manufacturers is stable. The dissolution behavior of benzoylmesaconine, benzoylaconine and benzoylhypaconine in samples form different manufacturers has some differences, which may be caused by the source of medicinal materials and preparation technology parameters.

ABSTRACT

This study aimed to investigate the influence of combinating Huangqi with Fuzi on the pharmacokinetics of six Aconitum alkaloids, i.e. aconitine (AC), hypaconitine (HA), mesaconitine (MA), benzoylaconine (BAC), benzoylhypaconine (BHA) and benzoylmesaconine (BMA). The plasma concentrations of the drugs were determined by LC-MS for dose response and time dependent curves. The pharmacokinetic parameters were calculated by DAS 3.3, and SPSS 12.0 was used to analyze the differences of main pharmacokinetic parameters between the two groups. Comparing with Fuzi group, the AUC0-t and AUC0-∞ of six alkaloids in Fuzi-Huangqi group was significantly decreased, the CLz/Fof six alkaloids except HA was significantly increased; the Cmax was decreased and the tmax was prolonged in 3 monoester alkaloids, and the apparent volume of distribution of BMA and MA (Vz/F) increases. These data indicated that Huangqi can inhibit the absorption of aconite alkaloids, induce the distribution of aconite alkaloids to the whole body, and accelerate the elimination of aconite alkaloids. The animal experiment scheme in this study has been approved by the Experimental Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine.

ABSTRACT

To compare the quality difference between Mahuang Xixin Fuzi decoction(MXF) prepared by traditional decocting method and that prepared by two commonly used decocting methods, and explore the scientific nature of the traditional decocting method. By taking effect-toxic components in MXF as the research object, this article investigated these three different decocting methods from the quantitative determination of effect-toxic components in MXF. By using multivariate statistical analysis methods, three characteristic constituents were identified as kakoul, mesaconitine (MA) and hypaconitine (HA) respectively. As compared with two commonly used decocting methods, MXF decoction prepared by traditional decocting method had the shortest boiling time, but with the lowest dissolution rates of MA and AC and the higher dissolution rates of mono-ester aconitum alkaloids. In addition, the traditional decocting method increased the dissolution of ephedra alkaloid and accelerated the hydrolysis of diester diterpenoid alkaloids. There were differences in the content of effect-toxic components in MXF decoctions prepared by three different decocting methods, which can provide a reference for use of the classical prescriptions.

ABSTRACT

Objective: Fuzi Banxia is one of eighteen antagonisms, previous studies have shown that the incompatibility could play special effects in the specific condition of diseases and appropriate compatible environment. The present study aims to evaluate the toxicity-efficacy of ginseng combined with Fuzi Banxia incompatibility intervening in the heart failure stage of cor pulmonale and to explore its mechanism. Methods: Monocrotaline (MCT)-induced cor pulmonale were used in this study. Ultra high-resolution small animal ultrasound real-time imaging system and the right heart catheterization were used to estimate cardiac function. Semi automatic biochemical analyzer was used to test myocardial enzyme LDH, CK, and CK-MB in serum. The heart tissues were stained with HE, and TUNEL assay was used to assess the pathomorphological changes and myocardial apoptosis. The expression of hypertrophy and apoptosis associated genes: ANP, BNP, β-MHC, Bax, and Bcl-2 in the right ventricle were determined by RT-PCR. Results: Fuzi Banxia combined with ginseng obviously attenuated mortality, decreased RVHI, and increased cardiac index; RVSP and mPAP were significantly reduced, and EF and FS were raised obviously; Myocardial enzymes LDH, CK, and CK-MB were pronounced attenuated; heart diameter reduced, right ventricular dilatation was significantly decreased, inflammatory cell infiltration notably reduced, and cardiac apoptosis rate was decreased obviously. Meanwhile, the expression of hypertrophy-related ANP, BNP, and β-MHC mRNA were up-regulated, the expression of apoptosis-related Bax mRNA was down-regulated, and the expression of anti-apoptosis-related Bcl-2 mRNA and Bcl-2/Bax ratio were up-regulated. Conclusion: Ginseng compatible environment could attenuate cardiac toxicity of Fuzi Banxia incompatibility intervening in the heart failure stage of cor pulmonale, and improve cardiac function, which may be related to the expression of hypertrophy and apoptosis associated genes, and thus delay the occurrence and development of heart failure.

ABSTRACT

To establish HPLC-MS/MS method for simultaneous determination of 14 toxic or active components in Fuzi formula granules, and further analyze the quality consistency of 29 batches of formula granules by considering the cluster analysis (CA), principal component analysis (PCA), and partial least squares discriminant analysis (PLS-DA) and other chemometrics methods. Phenomenonex Gemini C18 column (4.6 mm×150 mm, 5 μm) was used with 0.1% formic acid solution (A) -acetonitrile (B) as the mobile phase. The mass spectrum was scanned by ESI⁺ multiple reaction monitoring (MRM) mode. The contents of aconitine, mesaconitine, hypaconitine, Indaconitine, benzoylaconine, benzoylmesaconine, benzoylhypaconitine, aconine, fuziline, neoline, talatisamine, songorine, higenamine and salsoline were determined. The results showed that 14 compounds had a good linear relationship within their respective concentration range (R²>0.990 0). The limit of quantification was 2.07-7.71 mg·L⁻¹, and the average recovery was 96.07%-102.2%. The content determination results demonstrated that all batches of Fuzi formula granules had very low hypertoxic ingredients and high safety, while the content of active ingredients was greatly different. CA and PCA results showed that there were significant differences in the formula granules between two manufacturers; even though the different batches of samples from the same manufacturer had certain differences, but the difference in manufacturer A was less than that of B. Further PLS-DA showed that the content of cardiotonic substance salsola in the formula granules from manufacturer A was generally higher, while the contents of analgesic and anti-inflammatory substances benzoylmesaconitine and fuziline were generally lower than those in the products from manufacturer B. In conclusion, the safety of Fuzi formula granules was assured well, but the consistency needed to be improved. We recommend that all manufacturers establish strict standard for decoctions in the production process, and form a unified standard method to produce better Fuzi formula granules.

ABSTRACT

To preliminarily investigate the dissolution behavior of Fuzi Lizhong pill, provide the basis for its quality control and lay foundation for dissolution behavior by determining the dissolution rate of liquiritin and glycyrrhizic acid. High-performance liquid chromatography (HPLC) method for simultaneous content determination of the two active ingredients of liquiritin and glycyrrhizic acid in Fuzi Lizhong pill was established; The dissolution amount of these two active ingredients in fifteen batches of Fuzi Lizhong pill from five manufacturers was obtained at different time points, and then the cumulative dissolution rate was calculated and cumulative dissolution curve was drawn. The similarity of cumulative dissolution curve of different batches was evaluated based on the same factory, and the similarity of cumulative dissolution curve of different factories was evaluated based on the same active ingredients. The dissolution model of Fuzi Lizhong pill based on two kinds of active ingredients was established by fitting with the dissolution data. The best dissolution medium was 0.25% sodium lauryl sulfate. The dissolution behavior of liquiritin and glycyrrhizic acid in Fuzi Lizhong pill was basically the same and sustained release in 48 h. Three batches of the factories (factory 2, factory 3, factory 4 and factory 5) appeared to be similar in dissolution behavior, indicating similarity in dissolution behavior in most factories. Two of the three batches from factory 1 appeared to be not similar in dissolution behavior of liquiritin and glycyrrhizic acid. The dissolution data of the effective ingredients from different factories were same in fitting, and Weibull model was the best model in these batches. Fuzi Lizhong pill in 15 batches from 5 factories showed sustained release in 48 h, proving obviously slow releasing characteristics "pill is lenitive and keeps a long-time efficacy". The generally good dissolution behavior also suggested that quality of different batches from most factories was stable. The dissolution behavior of liquiritin and glycyrrhizic acid in different factories was different, suggesting that the source of medicinal materials and preparation technology parameters in five factories were different.

ABSTRACT

To investigate the protective effect and relevant mechanism of Fuzi Lizhong decoction (FZLZD) on liver of rats with non-alcoholic fatty liver disease (NAFLD), totally 32 male SPF Wistar rats were randomly divided into 4 groups: control group, model group, Yishanfu (YSF) group (200 mg·kg⁻¹·d⁻¹) and FZLZD group (10 g·kg⁻¹·d⁻¹), with 8 rats in each group. Rat model of NAFLD was prepared through the intragastric administration with fat emulsion for 4 weeks. After the successful modeling, rats in each administration group were continuously administered for 4 weeks. After 8 weeks, the rats in each group were put to death, and the pathological changes in liver tissue were detected by HE staining. Automatic biochemical analyzer was used to detect fasting serum lipid levels (T-Chol, TG, LDL-C, HDL-C) and liver functions (ALT, TP, ALB) of rats in each group. The rat liver index was calculated by weighing method. Enzyme-linked immunosorbent assay (ELISA) was used to detect the secretion of inflammatory cytokines TNF-α and IL-6 in liver tissue. Real-time quantitative PCR (qRT-PCR) was used to detect the mRNA expressions of fat metabolism-related factors SREBP-1c and FASN in liver tissue. Western blot was used to detect the p-AMPK and p-NF-κBp65 protein expressions in liver tissue. The results of HE staining showed that compared with the control group, the pathological changes in liver tissue in the model group rats were obvious; specifically, the outline of hepatic lobule was unclear, the hepatic cells showed diffuse steatosis of adipose tissue, and were accompanied by inflammatory infiltration, nuclear condensation, coloring deep; compared with the model group, liver lesions of all of the treatment groups were significantly alleviated; especially, the FZLZD group showed the most significant degree of remission. The results of serum test showed that the levels of serum lipids (T-Chol, TG, LDL-C, HDL-C), liver functions (ALT, TP, ALB) and liver index in model group were significantly higher than those in control group (<0.01); compared with the model group, the indexes of serum lipid and liver function of rats in each treatment group were significantly decreased (<0.01), and those in FZLZD group were significantly decreased (<0.05), while those in YSF group were not significantly changed. The results of ELISA and qRT-PCR showed that compared with the control group, the secretion levels of TNF-α, IL-6 and the mRNA levels of SREBP-1c and FASN in the liver tissue of model group rats were significantly increased (<0.01); compared with model group, the secretion levels of TNF-α, IL-6 and the mRNA levels of SREBP-1c, FASN in liver tissue of rats in each treatment group were significantly decreased (<0.01); compared with YSF group, the secretion levels of TNF-α and IL-6 and the mRNA levels of SREBP-1c and FASN in FZLZD group were significantly different (<0.01). Western blotting showed that compared with the model group, the protein expression of p-AMPK in liver tissue of rats in FZLZD group was significantly increased (<0.01), while the protein expression of p-NF-κBp65 was significantly decreased (<0.01). FZLZD can significantly improve hepatic pathological changes, reduce serum lipid levels, promote liver function and liver index in NAFLD rats, which may be associated with the activation of the AMPK pathway and thereby the inhibition of the expressions of SREBP-1c and FASN, and the inhibition of the NF-κBp65 pathway and thereby the reduction of the release of inflammatory factors.

ABSTRACT

AIM To observe the drug pair Baizhu-Fuzi's protection on the breast cancer nude mice with bony metastasis and to explore the mechanism of bone metastasis.METHODS Nude mouse models of breast cancer with bone metastasis were developed through injection of breast cancer cell MDA-MB-231BO into the left ventricle.Nude mice were randomly divided into group A and group B.Group A were subdivided into model group,zoledronic acid group and the drug pair of Baizhu-Fuzi group;and Group B were subdivided into sham-operation group,model group,zoledronic acid group and Baizhu-Fuzi group were subsequently administered with the intervention accordingly.The nude mice in group A had their surviving time and the weight changes observed;and those in group B had the degree of bone metastasis examined.Tartrate resistant acid phosphatase (TRAP) method for quantitative determination of osteoclast in bone metastasis,and ELISA method were employed to check the content of TGF-β1 and PTHrP in serum.RESULTS Compared to the model group,Baizhu-Fuzi group displayed distinctly longer survival time (P < 0.05),reduced rate of weight loss 6 weeks after modeling (P < 0.05),significantly declined degree of bone metastasis (P < 0.01),and significantly decreased quantity of TRAP (+) cell (P < 0.05) and serum TGF-β1 and PTHrP (P < 0.05).CONCLUSION The drug pair,Baizhu-Fuzi's influence in TGFβ signal path control and PTHrP expression reduction may contribute to the weight loss management,prolonged survival time,osteolytic bone defect rectification in mouse models of breast cancer with bone metastasis.

ABSTRACT

This study aimed to analyze the endogenous metabolite changes in the serum of mice infected with H1N1 virus after intervention by Mahuang-Xixin-Fuzi decoction (MXF) based on metabolomics method, investigate potential biomarkers and related metabolic pathways, and explore the therapeutic mechanism of MXF through metabolomics technology. Thirty-six Kunming (KM) mice were randomly divided into three groups: normal group, model group and MXF group. Influenza virus H1N1 was used by nasal drip to establish influenza mice model. The mice in MXF group were orally administrated with MXF for 6 consecutive days after inoculation, and the other two groups were given with equal volume of saline solution in the same way. Body weight, rectal temperature, morbidity and mortality were recorded daily. Serum samples were collected 24 hours after the last administration for HPLC-TOF-MS analysis. The results showed that as compared with the normal group, the body weight and rectal temperature were decreased in model group, and their lung index and mortality rate were significantly increased (P<0.05); MXF had good therapeutic effects on the abnormity of body weight, rectal temperature, lung index and high mortality rate of mice infected with H1N1 virus. The original data collected from the serum samples were analyzed with R language, MPP, SIMCA-P and other software, and significant changes were found in 14 kinds of endogenous substances from mice serum (P<0.05). As compared with model group, the potential metabolic markers in MXF group recovered to normal levels to a certain degree after being intervened by MXF. Further analysis with MetPA data platform showed that, the pathways involved in 14 metabolites included glucose metabolism, arachidonic acid metabolism, glycerophospholipids and sphingolipids metabolism etc. The metabolomics study and pharmacological experiment showed that MXF might play a role of efficacy by improving glucose metabolism, regulating arachidonic acid metabolism, glycerophospholipid and sphingolipid metabolic pathways.
