Myocardial ischemia-reperfusion injury （MIRI） is a major complication following coronary revascularization. Studies indicate that its pathophysiological mechanisms of MIRI are closely associated with oxidative stress， iron overload， inflammatory responses， and lipid peroxidation. Oxidative stress refers to an imbalance in redox homeostasis under pathological conditions， characterized by the abnormal accumulation of reactive oxygen species （ROS）， which disrupts the dynamic balance between pro-oxidant systems and antioxidant defense networks. In recent years， traditional Chinese medicine （TCM） has demonstrated unique advantages in the prevention and treatment of MIRI due to its multi-target and multi-pathway antioxidant properties. Research reveals that TCM primarily exerts protective effects against oxidative stress-induced MIRI by regulating signaling pathways such as nuclear factor erythroid 2-related factor 2 （Nrf2）， adenosine monophosphate-activated protein kinase （AMPK）， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， nuclear factor kappa-B （NF-κB）， Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3）， and protein kinase C beta Ⅱ/nicotinamide adenine dinucleotide phosphate oxidase 2/reactive oxygen species （PKCβⅡ/NOX2/ROS）. This article reviews recent literature on TCM monomers， compound formulas， and their active components， which alleviate oxidative stress to prevent and treat MIRI by modulating the aforementioned signaling pathways. It summarizes a concise overview of the molecular mechanisms by which oxidative stress-related signaling pathways lead to MIRI， discusses how TCM regulates these pathways to reduce oxidative stress-induced MIRI， and explores clinical application prospects and research challenges， aiming to provide a theoretical reference for the research and clinical management of MIRI.

Early-onset colorectal cancer (EOCRC) shows a different epidemiological trend compared to later-onset colorectal cancer, with its incidence rising in most regions and countries worldwide. However, the reasons behind this trend remain unclear. The etiology of EOCRC is complex and could involve both genetic and environmental factors. Apart from Lynch syndrome and Familial Adenomatous Polyposis, sporadic EOCRC exhibits a broad spectrum of pathogenic germline mutations, genetic polymorphisms, methylation changes, and chromosomal instability. Early-life exposures and environmental risk factors, including lifestyle and dietary risk factors, have been found to be associated with EOCRC risk. Meanwhile, specific chronic diseases, such as inflammatory bowel disease, diabetes, and metabolic syndrome, have been associated with EOCRC. Interactions between genetic and environmental risk factors in EOCRC have also been explored. Here we present findings from a narrative review of epidemiological studies on the assessment of early-life exposures, of EOCRC-specific environmental factors, and their interactions with susceptible loci. We also present results from EOCRC-specific genome-wide association studies that could be used to perform Mendelian randomization analyses to ascertain potential causal links between environmental factors and EOCRC.

Percutaneous coronary intervention(PCI),as one of the primary approaches for revascularization,still faces complications such as restenosis,myocardial ischemia-reperfusion injury and no-reflow/slow-flow phenomena,with no currently effective interventions ensuring long-term efficacy.Based on Li Dongyuan's theory that"fire and original qi cannot coexist",this article inherited Academician Chen Keji's academic perspective on"toxin-stasis pathogenesis"and the hemodynamic characteristics of coronary arteries to propose a"four-stage pathological progression"in post-PCI patients,namely spleen-stomach impairment-original qi deficiency-endogenous yin-fire-toxin-stasis accumulation.It emphasized that the heart vessels rely on qi and blood for nourishment and patency for function,elucidated the therapeutic rationale of Danggui Buxue Decoction,and presented the self-formulated Yixin Hemai Prescription,modified through syndrome differentiation,and performed simultaneous reinforcement and dredging,in order to provide diagnosis and treatment ideas for coronary heart disease after PCI treated with TCM.

OBJECTIVE To investigate the effect of betulin (BE) on the replication of rotavirus (RV) in vitro.METHODS ①MA104 cells were intervened with BE between 0.03125 and 64μmol·L-1 for 72 h,and MTT assay was used to detect the cell survival.② MA104 cells were infected with RV including Wa strains and SA-11 strains to establish a viral model.MA104 cells were divided into the cell control group,RV group and RV+BE groups.The cytopathic effect (CPE) method combined with MTT assay was used to detect the effect of BE on anti-RV adsorption,anti-RV biosynthesis and direct inhibition of RV.③The grouping was the same as in②,and RT-qPCR,Western blot and IF methods were used to detect the expression of RV structural protein VP6 after 24 h of BE incubation.④The grouping was the same as in②,and the ELISA kit was used to detect the concentrations of pro-inflammatory factors IL-6,IL-1β and TNF-α,anti-inflammatory factor IL-10 and type Ⅱ interferon IFN-γ in the cell supernatant after 24 h of BE incubation.⑤The grouping was the same as in②,and qPCR assay was used to detect the mRNA expression levels of Toll-like receptor 4 (TLR4),myeloid differentiation factor 88 (MYD88) and TNF receptor-associated factor 6 (TRAF6) after 24 h of BE incubation,Western blot assay was used to detect the expression levels of MYD88,IκBα,NF-κB p65,and p-NF-κB p65 after 24 h of BE incubation.RESULTS ① The maximum non-toxic concentration of BE towards MA104 cells was 1 μmol·L-1,and TC50 was 5.795 μmol·L-1.The concentrations of BE in the anti-RV experiments ranged from 0.03125μmol·L-1 to 1μmol·L-1.② In the anti-RV biosynthesis experiment,the inhibition rates of BE for RV-Wa between 0.0625 and 1 μmol·L-1 exceeded 50％,EC50 was 0.0485 μmol·L-1,and the value of TI was 119.48.The inhibition rates of BE for RV-SA-11 between 0.25 and 1 μmol·L-1 were above 50％,EC50 was 0.1226 μmol·L-1,and the value of TI was 47.27.In contrast,the effects of BE on anti-RV adsorption and direct inhibition of RV were not obvious.③ Compared with the RV group,BE inhibited the expression of VP6 (P＜0.01).④ Compared with the RV group,BE reduced the concentrations of IL-6,IL-1β and TNF-α(P＜0.01),but increased the concentrations of IL-10 and IFN-γ(P＜0.01).⑤Compared with the RV group,BE reduced the mRNA levels of TLR4,MYD88 and TRAF6 (P＜0.01),decreased the protein expression levels of MYD88 and p-NF-κB p65,and increased those of IκBα and NF-κB p65 (P＜0.01).CONCLUSION BE has anti-RV biosynthesis effect,and it may reduce inflammatory response caused by RV infection via TLR4/MYD88/NF-κB signaling pathway.

Objective To investigate the efficacy and safety of two-drug/three-drug neoadjuvant chemotherapy (NACT) for patients with locally advanced gastric/gastroesophageal junction adenocarcinoma. Methods A total of 112 patients with locally advanced gastric/gastroesophageal junction adenocarcinoma admitted to the Affiliated Tumor Hospital of Xinjiang Medical University from January 2016 to December 2021 were selected as study objects,and were divided into two-drug group (36 cases) and three-drug group (76 cases) according to the NACT regimen. All patients underwent at least 2 cycles of NACT followed by surgery. The therapeutic effect,disease-free survival (DFS) and overall survival (OS) were compared between two groups. Results The proportion of partial response in three-drug group was significantly higher than that in two-drug group (P<0.05). There were no significant differences in OS,DFS,R0 resection rate and tumor degradation between two-drug and three-drug groups (P>0.05). Multivariate Cox regression analysis showed that surgical method,pathological differentiation type,pathological stage of postoperative tumor,and nerve invasion were independent risk factors for OS (P<0.05),age,surgical method and pathological stage of postoperative tumor were independent risk factors for DFS (P<0.05). The proportion of severe anemia in three-drug group was significantly higher than that in two-drug group (P<0.05),and there were no significant differences in other adverse reactions between two groups (P>0.05). Conclusion The two-drug/three-drug NACT regimen have no significant effect on the long-term prognosis of patients,but the patient's age,pathological stage of postoperative tumor and pathological differentiation type have certain effects on the prognosis of patients.
