STUDY OF THE MECHANISM OF ARTEMISINE CAPILLARIES AND RADIX CURCUMAE PREVENTING GALLSTONE FORMATION INDUCED BY HIGH CHOLESTEROL DIET IN GUINEA PIGS

To study the effect of chinese herbal medicine preventing gallstone formation, morphology of livers and gallbladders as well as conjugated bile acids of the bile. 58 female guinea pigs were randomly divided into three groups. The control group was fed on normal diet; the lithogenous groups was high cholesterol diet (HCD) and the antilithic group was high cholesterol and the chinese herbal medicine capsule (13 5 g/kg). 8 weeks later the guinea pigs were killed. Liver and gallbladder were removed for light and electroscope observation. Gallbladder bile were withdrawn and gallbladder were collected. The minute construction of gallstones were observed by scanning electron microscope and gallstone components were quantified by Fourier Transform Infrand Spectros Copy (FT IR). The morphology of liver and gallbladder were observed by light microscope and transmission electron microscope. Conjugated bile acid of biles were determined by Thin layer Chromatograph. The effect of chinese herbal medicine preventing gallstone formation, morphololgy of livers and gallbladders as well as conjugated bile acids of the bile were also observed. We measured conjugated bile acids in all groups and found that decreased in lithogenic group and increased notably in antilithic group (P<0 01) . The gallstone formation rate was 100% when the animals were fed on HCD in lithogenic group. The rate decreased to 5 3% when the animals were fed on HCD and Chinese herbal medicine capsule inantilithic group. It indicates that changes in diet is an important factor in the process of gallstone formation and the chinese herbal medicine can prevent gallstone formation effectively.

Network pharmacology-based analysis on the anti-hepatocellular carcinoma effect of Curcumae Radix

As a traditional Chinese medicine,Curcumae Radix(CR)has exhibited anti-hepatocellular carcinoma(HCC)activity.However,the underlying molecular mechanism is still unclear.In the present study,network pharmacology was utilized to reveal the mechanism of the effects of CR in HCC.The analysis of the network results showed that the active components of CR,including curcumin,naringenin,sitosterol,demethoxycurcumin,andβ-elemene,were closely related to the screened hub-targets,such as AKT1,TP53,MAPK8,MAPK1,JUN,STAT3,VEGFA,MAPK3,IL6,TNF,CCND1,EP300,EGFR,and ESR1.GO and KEGG analyses revealed that these targets were associated with pathways in cancer,proteoglycans in cancer,PI3K-Akt signaling pathway,AGE-RAGE signaling pathway in diabetic complications,MAPK signaling pathway,hepatitis B,hepatitis C,and other biological processes.The candidate active components of CR(curcumin and naringenin)prominently exhibited their antitumor effects by regulating PI3K-Akt signaling pathway,MAPK signaling pathway,hepatitis B and hepatitis C.This study successfully predicted,explained,and confirmed the multi-component,multi-target,and multi-channel characteristics of CR,which not only gave novel insights into the pharmacological and biological molecular mechanism of CR applying to HCC disease,but also provided a feasible method for discovering potential activated compounds from Chinese herbs.

Network Pharmacology-Based and Pharmacological Evaluation of the Effects of Curcumae Radixon Cerebral Ischemia-Reperfusion Injury

Objective: This study aimed to investigate the network pharmacology of curcumae radix(CR, Yujin) and explore the mechanism of CR in the treatment of cerebral ischemia-reperfusion injury(CIRI). Materials and Methods: Network analysis and pharmacological evaluation were performed to explore the protective role of CR to treat CIRI. The potential target genes of the active components and CIRI were identified using SwissTarget Prediction, Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine, GeneCards, and Online Mendelian Inheritance in Man. Furthermore, network analysis was performed using Cytoscape software.Gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the R software. In vivo experiments were performed using the water extract of CR(WECR) on PC12 cells induced by hypoxia/reoxygenation(H/R) to simulate ischemia/reperfusion injury. Results: The results exhibited that 21 active compounds identified in CR were associated with 73 targets of CIRI. Functional analysis showed that multiple pathways, including response to stress, regulation of apoptotic process, and hypoxia-inducible factor 1 signaling pathway, were significantly enriched. In addition, STAT3, IL4, HIFIA, and CTNNB1 were predicted to be the most important genes among the 36 hub genes. Furthermore, WECR treatment significantly improved PC12 cell injury and decreased apoptosis levels in cells induced by H/R, with malondialdehyde contents reduced and superoxide dismutase or glutathione peroxidase levels increased. Conclusions: Network analysis and pharmacological evaluation of CR could provide valuable directions for further research on CR and improve comprehension of CIRI.

Extracts from Huangqi(Radix Astragali Mongoliciplus) and Ezhu(Rhizoma Curcumae Phaeocaulis) inhibit Lewis lung carcinoma cell growth in a xenograft mouse model by impairing mitogen-activated protein kinase signaling, vascular endothelial growth factor prod

OBJECTIVE: To study the anti-tumor effects of the extracts from Huangqi(Radix Astragali Mongolici)and Ezhu(Rhizoma Curcumae Phaeocaulis) on the growth of Lewis lung carcinoma(LLC) in a xenograft mouse model and to investigate the possible underlying mechanism.METHODS: LLC tumor-bearing C57 BL/6 mice were treated with normal saline, cisplatin(2 mg/kg intraperitoneally every other day), or Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis)(1∶1, 2∶1, or 3∶1 ratio;5, 8, or 11 g/kg crude drug intragastrically every day) for 15 d.Body weights and tumor volumes were measured every other day. Tumors were excised on day 15 and analyzed. Tumor microvessel density(MVD)was assessed by immunohistochemical staining of CD34;and expression of vascular endothelial cell growth factor(VEGF), the mitogen-activated protein kinases p38 mitogen-activated protein kinase(MAPK), extracellular signal-regulated kinases 1 and 2(ERK1/2), and Jun N-terminal kinase(JNK)and their phosphorylated forms were assessed by Western blotting.RESULTS: Treatment with cisplatin caused a significant loss of body weight compared with controls,whereas Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) extract combinations had no effect. Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) significantly decreased tumor weight and tumor MVD compared with controls,and at the 3∶1 treatment group had similar efficacy to cisplatin in reducing MVD. Tumors from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) treatments also showed decreased p38 MAPK, p-p38 MAPK, ERK1/2, p-ERK1/2,JNK, and p-JNK expression compared with the control group(all P < 0.01). VEGF protein expression was significantly reduced in the 2∶1 and 3∶1 treatment groups compared with the control group(P < 0.01).CONCLUSION: Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) hindered LLC growth in the xenograft mouse model, possibly via inhibition of the MAPK signaling pathway, VEGF production, and tumor angiogenesis.

OBJECTIVE: To investigate the effect of optimal combination(E) of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on proliferation and apoptosis of A549 lung cancer cells and the possible mechanism underpinning the action.METHODS: A uniform design method was used to optimize the E of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) in A549 lung cancer cells. MTS assay was applied to analyze the effect of the component formula ofHuangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on A549 cells viability in various uniform design groups. A549 cells with exponential growth in routine culture were exposed to Co Cl_2(200 μmol/L) to mimic hypoxic conditions. Group 0 was treated with RPMI-1640, the group Co Cl_2 was treated with Co Cl_2(200 μmol/L),the group DDP + Co Cl_2 was treated with 4 mg/L Cisplatin injection(DDP) + Co Cl_2(200 μmol/L), and the drug group was treated with various dose of E(0.5 E, 1 E, 2 E) + Co Cl_2(200 μmol/L). All groups were cultured for 24 h. Cell apoptosis was measured by Annexin V-FITC/propidium iodide double staining and flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction(q RT-PCR) were employed to detect the protein and m RNA expression of B-celllymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax) and cysteinyl aspartate specific proteinase-3(caspase-3).RESULTS: The E obtained by the uniform design was comprise of 200 mg/L Astragalus polysaccharide(X1) and 32 mg/L Curcumin(X3). Group DDP+Co Cl_2, group 1 E + Co Cl_2 and group 2 E + Co Cl_2 promoted the apoptosis of A549 cells(P < 0.05). Group1 E + Co Cl_2 and group 2 E + Co Cl_2 had no statistically significant differences compared with the group DDP + Co Cl_2(P > 0.05). Compared with group 0, various doses of E + Co Cl_2 could up-regulate the expression of Bax and caspase-3 and down-regulate the expression of Bcl-2 at protein and m RNA levels(P < 0.05).CONCLUSION: Astragalus polysaccharide and Curcumin was the optimal combination of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Cur-cumae Phaeocaulis). E promoted the apoptosis of A549 cells. Combination of Astragalus polysaccharide and Curcumin increased the expression of Bax and caspase-3, and decreased the expression of Bcl-2 to initiate apoptosis in A549 cells under chemical-induced hypoxia.

Analysis of GC×GC fingerprints from medicinal materials using a novel contour detection algorithm:A case of Curcuma wenyujin

This study introduces an innovative contour detection algorithm,PeakCET,designed for rapid and efficient analysis of natural product image fingerprints using comprehensive two-dimensional gas chromatogram(GC×GC).This method innovatively combines contour edge tracking with affinity propagation(AP)clustering for peak detection in GC×GC fingerprints,the first in this field.Contour edge tracking signif-icantly reduces false positives caused by“burr”signals,while AP clustering enhances detection accuracy in the face of false negatives.The efficacy of this approach is demonstrated using three medicinal products derived from Curcuma wenyujin.PeakCET not only performs contour detection but also employs inter-group peak matching and peak-volume percentage calculations to assess the compositional similarities and differences among various samples.Furthermore,this algorithm compares the GC×GC fingerprints of Radix/Rhizoma Curcumae Wenyujin with those of products from different botanical origins.The findings reveal that genetic and geographical factors influence the accumulation of secondary metabolites in various plant tissues.Each sample exhibits unique characteristic components alongside common ones,and vari-ations in content may influence their therapeutic effectiveness.This research establishes a foundational data-set for the quality assessment of Curcuma products and paves the way for the application of computer vision techniques in two-dimensional(2D)fingerprint analysis of GC×GC data.

Research Progress and Prospects on the Anti-liver Fibrosis,Blood Circulation-promoting and Stasis-resolving Effects of Curcuma kwangsiensis Based on W-P Bodies

Liver fibrosis is a necessary stage in the progression of chronic liver disease to cirrhosis.So far,no satisfactory drugs have been found to intervene in liver fibrosis.Liver microcirculation disorders are one of the important pathogenesis of chronic liver disease,and hepatic sinusoidal endothelial cells(HSECs)are the main cells that constitute the liver microcirculation barrier.In clinical practice,W-P bodies have been detected in HSECs of most patients with liver fibrosis.W-P bodies serve as a site for the synthesis and storage of vW factors,ET-1 and other cytokines that promote liver fibrosis.They can disrupt the structure and function of HSECs,cause liver microcirculation disorders,and exacerbate the progression of liver fibrosis.Previous studies have found that the Guangxi specialty ethnic medicine,C.kwangsiensis S.G.Lee et C.F.Liang,has definite effects in promoting blood circulation,resolving blood stasis,and resisting liver fibrosis.Based on this,a further research idea has been derived,stating that the blood circulation-promoting,blood stasis-resolving,and anti-liver fibrosis effects of C.kwangsiensis are produced by affecting the formation of W-P bodies,the synthesis and storage of contents in W-P bodies,and intervening in their exocytosis capacity.
