Me.otis： Human umbilical vein endothelial cells （HUVECs） were treated with 0 mg/mL, 0.25 mg/mL, 0.5 mg/mL, and 1 mg/mL of PZH for 24 h, 48 h and 72 h, respectively. Chicken embryo chorioallantoic membrane （CAM） model was used to evaluate in vivo angiogenesis. An ECMatrix gel system was used to evaluate in vitro angiogenesis by examining the tube formation of HUVECs. 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide assay was performed to determine HUVEC viability. Cell density of HUVECs was observed by phase- contrast microscopy. HUVEC migration was determined by wound healing method. The mRNA and protein expression of vascular endothelial growth factor A （VEGF-A） and basic fibroblast growth factor （bFGF） in both HUVEC and human colon adenocaminoma cells （HT-29） was examined by reverse transcription polymerase chain reaction （RT-PCR） and enzyme linked immune sorbent assay （ELISA）, respectively. Results： PZH treatment significantly reduced the total number of blood vessels compared with the untreated control in the chicken embryos and resulted in a significant decrease in capillary tube formation and cell density of HUVECs （P〈0.05）. In addition, treatment with 0.25-1 mg/mL of PZH for 24 h, 48 h, and 72 h respectively reduced cell viability by 9%-52%, 24%-87% or 25%-87%, compared with the untreated control cells （P〈0.05）. Moreover, PZH treatment decreased the migration of HUVECs. Furthermore, PZH close-dependently suppressed the expression of VEGF-A and bFGF on both mRNA and protein levels （P〈0.05）. Conclusion： PZH could inhibit angiogenesis in vivo in CAM model and in vitro on HUVECs, suggesting that inhibiting tumor angiogenesis might be one of the mechanisms by which PZH treats cancer.展开更多

Western blotting was performed to determine protein levels of PNO1, p53, and p21. HCT-8 cells were transduced with a lentivirus over-expressing PNO1. Colony formation assay was used to detect cell survival in PNO1 overexpression of HCT-8 cells after PZH treatment. Cell-cycle distribution, cell viability and cell apoptosis were performed to identify the effect of PNO1 overexpression on cell proliferation and apoptosis of HCT-8 cells after PZH treatment. Xenograft BALB/c nude mice bearing HCT116 cells transduced with sh-PNO1 or sh-Ctrl lentivirus were evaluated. Western blot assay was performed to detect PNO1, p53, p21 and PCNA expression in tumor sections. Terminal deoxynucleotidyl transferase dUTP nick end labling (TUNEL) assay was used to determine the apoptotic cells in tissues.ResultsPZH treatment decreased cell viability, down-regulated PNO1 expression, and up-regulated p53 and p21 expressions in HCT-8 cells (P<0.05). PNO1 overexpression attenuated the effects of PZH treatment, including the expression of p53 and p21, cell growth, cell viability, cell cycle arrest and cell apoptosis in vitro (P<0.05). PNO1 knockdown eliminated the effects of PZH treatment on tumor growth, inhibiting cell proliferation inhibition and apoptosis induction in vivo (P<0.05). Similarly, PNO1 knockdown attenuated the effects of PZH treatment on the down-regulation of PNO1 and up-regulation of p53 and p21 in vivo (P<0.05).ConclusionThe mechanism by which PZH induces its CRC anti-proliferative effect is at least in part by regulating the expression of PNO1 and its downstream targets p53 and p21.展开更多

Methods: 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay was used to determine the cell viability. Adriamycin (ADR) staining observed by fluorescence microscope was performed to detect the accumulation of ADR. Transwell assay was used to analyze the cell migration and invasion. Western-blot was performed to detect the protein expression of related genes. Results: MCF-7/ADR cells were resistant to ADR treatment, and PZH treatment inhibited the viability of MCF-7/ADR cells in a dose-dependent manner. PZH treatment also increased the intercellular accumulation of ADR and down-regulated the expression of ABCG2 and ABCB1 in MCF-7/ADR cells (P<0.05). In addition, PZH treatment inhibited EMT, migration and invasion of MCF-7/ADR cells (P<0.05). Moreover, PZH suppressed activation of transforming growth factor β 1 (TGF-β) signaling in MCF-7/ADR cells (P<0.05). Conclusion: PZH treatment can effectively overcome chemoresistance via down-regulating ABCG2, ABCB1 and inhibit EMT in ADR resistant human breast cancer cells via suppression of the TGF-β 1 pathway.展开更多

文摘Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is unknown.Here,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the activation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signalling.Mechanistically,PZH stimulated signal transducer and activator of transcription 3(STAT3)phosphorylation to induce the expression of A20,which could inhibit the activation of NF-κB and MAPK signalling.Knockdown of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on STAT3 phosphorylation and A20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by activating TGR5.Consistently,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-STAT3 and A20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory cytokines.Overall,our study identifies BAs as the effective components in PZH that activate TGR5-STAT3-A20 signalling to ameliorate LPS-induced sepsis.

文摘Objective: To evaluate the effect of Pien Tze Huang (片仔癀, PZH) on breast cancer chemo resistance and related epithelial-mesenchymal transition (EMT) and investigate the underlying mechanisms. Methods: 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay was used to determine the cell viability. Adriamycin (ADR) staining observed by fluorescence microscope was performed to detect the accumulation of ADR. Transwell assay was used to analyze the cell migration and invasion. Western-blot was performed to detect the protein expression of related genes. Results: MCF-7/ADR cells were resistant to ADR treatment, and PZH treatment inhibited the viability of MCF-7/ADR cells in a dose-dependent manner. PZH treatment also increased the intercellular accumulation of ADR and down-regulated the expression of ABCG2 and ABCB1 in MCF-7/ADR cells (P<0.05). In addition, PZH treatment inhibited EMT, migration and invasion of MCF-7/ADR cells (P<0.05). Moreover, PZH suppressed activation of transforming growth factor β 1 (TGF-β) signaling in MCF-7/ADR cells (P<0.05). Conclusion: PZH treatment can effectively overcome chemoresistance via down-regulating ABCG2, ABCB1 and inhibit EMT in ADR resistant human breast cancer cells via suppression of the TGF-β 1 pathway.

文摘BACKGROUND Traditional Chinese medicine has used the drug Pien Tze Huang(PTH),a classic prescription,to treat autoimmune hepatitis(AIH).However,the precise mode of action is still unknown.AIM To investigate the mechanism of PTH in an AIH mouse model by determining the changes in gut microbiota structure and memory regulatory T(mTreg)cells functional levels.METHODS Following induction of the AIH mouse model induced by Concanavalin A(Con A),prophylactic administration of PTH was given for 10 d.The levels of mTreg cells were measured by flow cytometry,and intestinal microbiota was analyzed by 16S rRNA analysis,while western blotting was used to identify activation of the toll-like receptor(TLR)2,TLR4/nuclear factor-κB(NF-κB),and CXCL16/CXCR6 signaling pathways.RESULTS In the liver of mice with AIH,PTH relieved the pathological damage and reduced the numbers of T helper type 17 cells and interferon-γ,tumor necrosis factor-alpha,interleukin(IL)-1β,IL-2,IL-6,and IL-21 expression.Simultaneously,PTH stimulated the abundance of helpful bacteria,promoted activation of the TLR2 signal,which may enhance Treg/mTreg cells quantity to produce IL-10,and suppressed activation of the TLR4/NF-κB and CXCL16/CXCR6 signaling pathways.CONCLUSION PTH regulates intestinal microbiota balance and restores mTreg cells to alleviate experimental AIH,which is closely related to the TLR/CXCL16/CXCR6/NF-κB signaling pathway.
文摘This article details a public acupuncture demonstration that took place on May 9,1972,in San Francisco,California.It was conducted by two traditional Chinese medicine doctors Pien Bae Chi(卞伯岐)and Leung Kok Yuen(梁觉玄),and was observed by 500 American medical doctors.This was an important public acupuncture demonstration in the early history of acupunccture in the United States(US).It directly promoted the passage of the first acupuncture bill by California government and had a significant impact on the legalization of acupuncture in California.
文摘Epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI)plays an important role in cancer therapy.However,EGFR is highly expressed in the skin and gives rise to one of the most concerning issues for the EGFR-TKI treatment,namely skin toxicity.Antibiotics and corticosteroids are usually used to treat the EGFR inhibitor-associated skin rash,with prominent side effects over long-time use.Pien Tze Huang(PZH)Unguentum Compositum is a traditional product for external application which is made of traditional Chinese medicine and oil base.Herein,we reported the case of a 50-year-old man who presented with skin rash on the face,head,and back induced by an EGFR-TKI named erlotinib.By using PZH Unguentum Compositum,we observed that the skin rash was mitigated and eventually disappeared.This case report suggests that PZH Unguentum Compositum may be an effective therapy in treating skin rash caused by EGFR-TKI with fewer side effects.

文摘OBJECTIVE:To explore biomarkers of Pien Tze Huang(片仔癀)that ameliorated the symptoms of hepatic fibrosis.METHODS:Two groups of carbon tetrachloride-induced hepatic fibrosis(HF)mice model were constructed in our study:one group received PZH treatment and another group received no treatment.We performed this study to investigate the role of PZH in the regulation process of hepatic fibrosis.RESULTS:We identified 31 down-regulated and 39 upregulated mi RNAs using small RNA-seq analysis.Combining RNA-Seq data analysis,our study revealed 7 significant target genes(Sp4,Slc2 a6,Tln2,Hmga2,Ank3,Pax9,Fgf9).The results of real-time quantitative polymerase chain reaction analysis suggested that the expression level of 6 genes(Sp4,Tln2,Hmga2,Ank3,Pax9,Fgf9)were down-regulated compared to control group.On the other hand,the expression level of Slc2 a6 appeared to be up-regulated.The protein mass spectrometry showed that PZH group had lower protein expression of Tln2 compared to control group.CONCLUSION:We identified 7 genes that were significantly related to PZH response in HF mice using multiple conjoint analysis methods.These genes could participate in underlying regulation mechanism of hepatic fibrosis during PZH treatment.
