Objective To investigate the underlying mechanisms of the effect of Fufang Changtai Decoction(FFCT)in inhibiting colorectal cancer(CRC)through the ferroptosis pathway using network pharmacology combined with experimental validation.Methods The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and Swiss Target Prediction databases were employed for the systematic screening of potent active ingredients and therapeutic targets of FFCT.In addition,the identification of CRC-associated genes and ferroptosis-related genes(FRGs)was accomplished using the Gene Cards and FerrDb databases,respectively.Venn diagrams,coupled with Cytoscape software,facilitated the comprehensive analysis of key FRGs involved in FFCT's intervention in CRC by mapping the TCM compound-therapeutic target network.Transmission electron microscopy was used to examine the mitochondrial ultrastructure of SW480 and HCT116,2 Human CRC cell lines,after treatment with FFCT-containing serum.Intracellular reactive oxygen species(ROS)levels were measured using a ROS detection kit.To assess the role of ferroptosis,ferroptosis inhibitor liproxstatin-1(Lip-1)was co-administered with FFCT-containing serum.The effects on cancer cell viability and proliferation were evaluated using CCK-8 and colony formation assays.Key molecular targets involved in the regulatory effects of FFCT on the expression of FRGs were further analyzed using PCR Array and Western blot.The findings were then validated with human CRC tissue microarrays.Results A total of 103 active ingredients of FFCT,739 therapeutic targets,9 101 disease-related genes,and 564 FRGs were identified.Venn diagram analysis identified 81 FRGs associated with FFCT intervention.Network analysis revealed that NQO1,TP53,and PTGS2 served as hub nodes in the regulatory network.Findings from the in vitro experiments showed that FFCT induced ferroptosis changes,including mitochondrial condensation,membrane thickening,and cristae reduction,in SW480 and HCT116 cells.FFCT treatment significantly increased intracellular ROS levels in a dose-dependent manner(P<0.05)and reduced cancer cell viability and proliferative capacity(P<0.01).These inhibitory effects were partially reversed by Lip-1,suggesting that FFCT's antitumor activity was closely associated with the ferroptosis pathway.PCR Array and Western blot analyses further confirmed that FFCT significantly downregulated NQO1 mRNA and protein expression in cancer cells(P<0.001),which was consistent with network pharmacology predictions.Immunofluorescence analysis of clinical CRC tissue microarrays revealed that NQO1 expression was significantly higher in tumor tissues than in adjacent non-tumor tissues(P<0.001).Conclusion FFCT may induce intracellular ferroptosis by downregulating the oncogenic gene NQO1,thereby exerting anti-CRC effects.

The intestine and liver are closely connected both physiologically and pathologically, forming a so-called gut-liver axis, with the gut microbiota serving as a pivotal link in their bidirectional communication. Gut microbiota dysbiosis and gut-liver axis disruption play a key role in the development and progression of colorectal cancer liver metastasis (CRLM), though the underlying mechanisms have not been clearly elucidated. Certain gut microbiota, such as Escherichia coli and Enterococcus spp., can breach the intestinal barrier and translocate to the liver, promoting the formation of pre-metastatic niche. Fusobacterium nucleatum and Enterococcus faecalis enhance tumor cell invasion/migration, while Parabacteroides spp. suppress anti-tumor immunity in the liver TME. Interventions like fecal microbiota transplantation, dietary modifications, and traditional Chinese medicine have shown potential in clinical and preclinical studies to improve patient outcomes by targeting the gut microbiota, but their long-term efficacy and safety require further investigation. Future research should focus on elucidating the effects of specific bacterial species, metabolites, viruses, and fungi on tumorigenesis. Exploring the potential of gut microbiota-based precision medicine and personalized therapies will improve risk stratification and enable more targeted interventions for CRLM patients.

Objective: To investigate the prevalence of dyslipidemia and the level of blood lipids among Tajik people in Pamir Plateau, Xinjiang, and explore the related factors of dyslipidemia. Methods: It is a retrospective cross-sectional study. A multi-stage cluster random sampling survey was conducted among 5 635 Tajiks over 18 years old in Tashkorgan Tajik Autonomous County, Xinjiang Province from May to October 2021. Data were collected through questionnaire survey (general information, medical history, and personal history), physical examination (height, weight, waist, and blood pressure) and blood test (total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density cholesterol (HDL-C)) to analyze the dyslipidemia and its risk factors among Tajiks. Results: The age of Tajik participants was (41.9±15.0) years, including 2 726 males (48.4%). The prevalence of borderline high TC, high LDL-C and high TG levels were 17.2%, 14.7% and 8.9%, respectively. The prevalence of high TC, high LDL-C, high TG and low HDL-C were 4.1%, 4.9%, 9.4% and 32.4%, respectively, and the prevalence of dyslipidemia was 37.0%. There is a positive correlation between male,higher education level, higher body mass index (BMI) value,waist circumference, living in town, smoking and dyslipidemia. Conclusions: The low prevalence of high TC, high LDL-C, high TG and high prevalence of low HDL-C was a major characteristic of Tajik people in Pamir Plateau of Xinjiang. The lower rates of overweight and obesity may be one of the reasons for the lower prevalence of dyslipidemia among Tajik.
