The medium-temperature T dependence of the jet transport coefficient̂q was studied via the nuclear modification factor RAA(p_(T))and elliptical flow parameter v_(2)(p_(T))for large transverse momentum p_(T) hadrons in high-energy nucleus-nucleus *** a next-to-leading-order perturbative QCD parton model for hard scatterings with modified fragmentation functions due to jet quenching controlled by q,we check the suppression and azimuthal anisotropy for large p_(T) hadrons,and extract q by global fits to RAA(pT)and v_(2)(pT)data in A+A collisions at RHIC and LHC,*** numerical results from the best fits show that q∕T^(3) goes down with local medium-temperature T in the parton jet *** with the case of a constant q∕T^(3),the going-down T dependence of q∕T^(3) makes a hard parton jet to lose more energy near T_(c) and therefore strengthens the azimuthal anisotropy for large pT *** a result,v_(2)(p_(T))for large pT hadrons was enhanced by approximately 10%to better fit the data at RHIC/*** the first-order phase transition from QGP to the hadron phase and the additional energy loss in the hadron phase,v_(2)(p_(T))is again enhanced by 5-10%at RHIC/LHC.

Objective: The purpose of this research was to examine the potential anticancer properties of Xiao Tan San Jie Fang(XTSJF) and its potential mechanism of action against colorectal cancer. Materials and Methods: HCT116 cells were induced into HCT116 spheres in DMEM/F12 medium by treatment with epidermal growth factor + fibroblast growth factor + leukemia inhibitory factor + B27. The proliferation ability and stemness of HCT116 spheres was examined. Various concentrations of XTSJF were used to treat HCT116 spheres to observe the impact on proliferation, apoptosis, and expression of stem cell markers. Next, Wnt/β-catenin pathway-related factor proteins were detected. Results: The findings revealed that XTSJF suppressed cell growth and induced cell death in HCT116 cells in a dosage-dependent manner. Similarly, XTSJF promotes apoptosis, inhibits cell proliferation, prolongs survival, and maintains the expression of stem cells through the Wnt/-catenin/TCF4 axis. XTSJF also inhibits AKT activity and subsequently activates glycogen synthesis kinase-3β expression, inhibiting Wnt/beta-catenin pathway activity and downstream target gene transcript expression. The Wnt/β-catenin signaling pathway is inhibited by the XTSJF, leading to the suppression of colon cancer stem cell proliferation. Conclusion: Xiaotan Sanjie Prescription inhibited colon cancer stem cell growth through Wnt/β-catenin signaling pathway.
