At the 12-month follow-up, the two groups showed a similar reduction of symptoms. However, preliminary evidence indicates that MBCT has a superior effect on some aspects of OCD. This should be replicated in future studies.Background Traditionally, seeds of Herpetospermum pedunculosum were used to treat liver disease or cholepathy. Up to date, their protecting effect against cholestasis was remain unclarified. Purpose To investigate the efficacy, possible mechanisms, and active constituents of the ethyl acetate extract from the seeds of Herpetospermum pedunculosum (HPEAE), studies were carried out using cholestasis rat model induced by α-naphthylisothiocyanate (ANIT). Methods Male rats were intragastrically treated with HPEAE (100, 200 or 400 mg/kg) once a day for 7 days and were modeled with ANIT (60 mg/kg). The levels of serum indicators, bile flow, and histopathology were evaluated. Indices of oxidative stress and inflammatory mediators were detected using the enzyme-linked immunosorbent assay. Western blotting method was employed for analyzing the protein levels in the signal pathways of farnesoid X receptor (FXR), kelch ech associating protein 1/nuclear factor erythroid 2-related factor 2 (Keap1/Nrf2) and nuclear factor κBase and malondialdehyde were markedly restored by treatment with HPEAE. Western blotting further confirmed that HPEAE up regulated the expression of quinone oxidoreductase 1, heme oxygenase 1 and Keap1, lowered the expression of Nrf2 and reduced oxidative stress. HPEAE also up regulated P-glycoprotein 65, phosphorylated P-glycoprotein 65 and inhibitor of NF-κB kinase α expression, down regulated inhibitor of NF-κB (IκB), restored inflammatory mediator tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6 and IL-10, and reduced inflammatory response. Fifteen compounds were identified (12 lignans and 3 coumarins). Among them, five lignans exhibited the significant FXR agonistic activity in vitro. Conclusion HPEAE may alleviate the cholestasis and liver injury caused by ANIT in rats by activating FXR, as well as suppressing the Keap1/Nrf2 and NF-κB signaling pathways and lignans may be its main active components.Background Although Bushenhuoxue formula (BSHXF) is successfully used as a non-traumatic therapy in treating bone fracture in China, the molecular mechanism underlying its effects remains poorly understood. Purpose The present study aims to explore the therapeutic effects of BSHXF on fracture healing in mice and the underlying mechanism. Methods We performed unilateral open transverse tibial fracture procedure in C57BL/6 mice which were treated with or without BSHXF. Fracture callus tissues were collected and analyzed by X-ray, micro-CT, biomechanical testing, histopathology and quantitative gene expression analysis. Tibial fracture procedure was also performed in Cre-negative and Gli1-CreER; Tgfbr2flox/flox conditional knockout (KO) mice (Tgfbr2Gli1ER) to determine if BSHXF enhances fracture healing in a TGF-β-dependent manner. In addition, scratch-wound assay and cell counting kit-8 (CCK-8) assay were used to evaluate the effect of BSHXF on cell migration and cell proliferation in C3H10T1/2 mesenchymal stem cells, respectively. Results BSHXF promoted endochondral ossification and enhanced bone strength in wild-type (WT) or Cre- control mice. In contrast, BSHXF failed to promote bone fracture healing in Tgfbr2Gli1ER conditional KO mice. In the mice receiving BSHXF treatment, TGF-β/Smad2 signaling was significantly activated. Moreover, BSHXF enhanced cell migration and cell proliferation in C3H10T1/2 cells, which was strongly attenuated by the small molecule inhibitor SB525334 against TGF-β type I receptor. Conclusion These data demonstrated that BSHXF promotes fracture healing by activating TGF-β/Smad2 signaling. BSHXF may be used as a type of alternative medicine for the treatment of bone fracture healing.Background Compound Kushen Injection (CKI), a well-known Chinese Medicine preparation, has been used to treat non-small cell lung cancer (NSCLC) for more than 15 years, and its clinical curative effect is considered to be beneficial. Hypothesis/purpose This study was designed to evaluate the effects and underlying mechanisms of CKI against NSCLC using an ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS)-based plasma metabolomics approach. https://www.selleckchem.com/products/sd49-7.html Methods 4',6-diamidino-2-phenylindole (DAPI) staining and 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) dye reduction assay were employed to assess apoptosis and the viability of A549 cells with and without CKI treatment. The weight/volume of Lewis lung carcinoma (LLC) sarcomas and histopathological examinations were used to evaluate the anti-tumor effects of CKI against NSCLC. A UPLC-Q-TOF/MS method combined with multivariate data analysis was developed to characterize metabolomic fingerprinting aolipid metabolism is a crucial feature of cancer-specific metabolism, the enzymes that are involved in 1-acyl-sn-glycero-3-phosphoinositol biosynthesis were further evaluated. Western blotting results indicated that CKI modulated the abnormal biosynthesis pathway of 1-acyl-sn-glycero-3-phosphoinositol by activation of cytidine diphosphate-diacylglycerol-inositol 3-phosphatidyltransferase (CDIPT) and cytosolic phospholipase A2 (cPLA2), and by inhibition of lysophosphatidic acid acyltransferase gamma (AGPAT3). Conclusion This study demonstrated that CKI has a favorable anti-tumor effect and that a UPLC-Q-TOF/MS-based metabolomics method in conjunction with further verifications at the biochemical level is a promising approach for investigating its underlying mechanisms.Background and purpose Gastric cancer is one of the major malignancies worldwide. Epiberberine (EPI) is a major alkaloid from Coptis chinensis Franch and the antitumor property of EPI remains poorly understood. Method The inhibition on gastric cancer cells was observed by MTT assays and colony formation experiments. The apoptosis, cell cycle, and reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) in gastric cancer cells were analyzed by Flow cytometry. The anti-tumor effect of EPI was evaluated with the MKN-45-beraring nude mice, and the potential mechanisms were explored by RNA-seq, qPCR, siRNA silencing and western blotting. Results EPI inhibited the proliferation of human gastric cancer cell lines MKN-45 (harboring wild-type p53) and HGC-27 (harboring mutant p53) in a dose dependent manner. EPI induced the apoptosis and cell cycle arrest in these two cell lines, of which MKN-45 cells are more sensitive to EPI than HGC-27 cells. Further experiments indicated that EPI induced the accumulation of ROS and decreased of ΔΨm in MKN-45 cells.
