Introduction there is currently no standard treatment for relapsed and arsenic trioxide(ATO)-resistant acute promyelocytic leukemia(APL).Here,we report a case series of realgar-indigo naturalis formula(RIF)for the successful treatment of patients with relapsed and ATO-resistant *** presentation Two patients in the first relapse and one in the second relapse failed to achieve hematologic complete remission(HCR)when reinduced by ATO;the other five patients progressed to relapse during ATO-based regimens for post-remission *** eight patients received RIF in three doses per day totaling 130 mg/kg(≤30 pills)as induction therapy and achieved HCR at a median time of 46.5 *** received 5 years of post-remission therapy,which consisted of combined chemotherapy followed by *** this period,the patients did not experience renal dysfunction or QT interval *** the last follow-up,three patients survived without relapse,two patients survived with a second or third relapse and third or fourth remission,and the other three patients relapsed for a third or fourth time and *** 5-year overall survival and event-free survival rates were 75.0%(95%confidence interval[CI]:31.5–93.1)and 37.5%(95%CI:5.6–71.7),*** RIF for induction therapy and RIF combined with chemotherapy for post-remission therapy may represent an effective and safe protocol for the treatment of patients with relapsed and ATO-resistant APL.

In this work, we study the impact of treatments at different stages of Human Immunodeficiency Virus (HIV) and Tuberculosis (TB) co-infection in a population under the influence of random perturbations. this is achieved by constructing a stochastic epidemic model describing the transmission and treatment of the diseases. the model is created with the assumption that transmission rates fluctuate rapidly compared to the evolution of the untreated diseases. the basic reproduction numbers corresponding to the population with HIV infection only (with n stages of infections and treatments), the population with tuberculosis infection only, and the overall population with co-infection (with n stages of infection/treatments) are derived in the presence and absence of noise perturbations. these are used to discuss the long term behavior of the population around a disease-free equilibrium and an endemic equilibrium, and to analyze the effect of noise and treatments on the system. We also showed conditions under which TB infected population dynamic undergoes backward bifurcation and give conditions for disease eradication in the entire population. Analysis shows that small perturbations to the disease-free equilibrium can initially grow under certain conditions, and the introduction of TB treatment is effective in eliminating the co-infection. Numerical simulations are presented for validation of our results using published parameters.

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.
