Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Objective: To study the efficacy of photosensitizer 8- methoxsalen (8-MOP) combined with ultraviolet radiation A (UVA) in inducing ferroptosis in mouse melanoma B16 cells, and to assess the resultant changes in immunogenicity, and their impact on subsequent immune activation after treatment. Methods: 1) Mouse melanoma B16 cells were cultured and treated with 8-MOP (100 ng/mL) and UVA (4 J/cm ), and then cultured in a constant temperature incubator (37℃, 5%CO ) for 24 hours after irradiation. 2) CCK8 (cell proliferation and toxicity) detection kit was used to detect the death rate of tumor cells. 3) LPO (lipid peroxide) and GSH (glutathione) detection kits were used to detect the degree of oxidative damage of tumor cells; Changes of Fe , mitochondrial membrane potential (JC-1) and BODIPY 581/591 C11 (lipid peroxidation detection kit) in tumor cells were detected by confocal microscope. Western blotting (WB) was performed to detect GPX4, SLC7A11 and NCOA4 to confirm ferroptosis. 4) The expression of HMGB1 (high mobility group protein 1), ATP and CRT (calreticulin) in the supernatant of tumor cell culture was detected by ELISA kit to evaluate the immunogenicity of tumor cells. 5) 1×10 B16 cells were injected subcutaneously into the skin of the back and neck of mice at a dose of 100 μL to construct a mouse melanoma model. Spleen mononuclear cells of tumor-bearing mice were extracted and immediately co-cultured with irradiated tumor cells for 48 h. Changes of dendritic cell (DC) maturity were detected by MHC-II, CD11c, CD80 and CD83 flow cytometry. Results: After UVAP, the survival rate of B16 cells decreased significantly (61.39±6.823 vs 84.81±7.026 vs 100.0±3.996, P<0.000 1, P<0.01). UVAP effectively induced ferroptosis in B16 cells, characterized by increased LPO and C11-bodipy lipid peroxidation, GSH depletion, Fe accumulation, mitochondrial membrane depolarization, decreased GPX4 and SLC7A11 protein expression, and increased NCOA4 expression, all in line with the trend of ferroptosis. UVAP also enhanced tumor cell immunogenicity, evidenced by elevated release of ATP, CRT, and HMGB1. The immunogenicity of B16 cells increased, the expressions of ATP, CRT and HMGB1 increased, and the DC maturity increased (CD80: 31.92±4.071 vs 19.77±3.177; CD83: 21.40±4.787 vs 12.19±1.487, P<0.001, P<0.01). Conclusion: The combined action of 8-MOP and UVA can induce ferroptosis in B16 tumor cells, enhance the immunogenicity of tumor cells, release more tumor antigens, promote the maturation of DC, present antigens better, thereby facilitating subsequent immune activation.

Objective:To investigate corneal transparency alteration in patients with type 2 diabetes and its influencing factors.Methods:A case-control study was conducted.A total of 52 patients with type 2 diabetes mellitus (DM) (104 eyes) and 23 age-matched healthy controls (46 eyes) were enrolled as DM group and normal control group in the Second Affiliated Hospital of Anhui Medical University from October 1, 2020 to October 30, 2021.Patients with DM were further divided into non-diabetic retinopathy (non-DR) and DR groups according to their fundus conditions.Corneal densitometry (CD) was evaluated using the Pentacam.According to its built-in program, the cornea was divided into anterior, intermediate, and posterior layers and subdivided into 0-2 mm, >2-6 mm, >6-10 mm, and >10-12 mm annular regions with the corneal apex as the center of the circle.Pentacam automatically calculated the CD value of each corneal layer and region as well as the total CD value.The influencing factors of total CD value in diabetes group were analyzed by a multivariate linear regression analysis model.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the Second Affiliated Hospital of Anhui Medical University (No.YX2023-129[F1]).Written informed consent was obtained from each subject before any medical examination.Results:The total CD value of diabetes group was 20.24±3.10, which was significantly higher than 18.79±3.31 of normal control group ( t=-2.583, P=0.011).The CD values of the anterior layer, intermediate layer, 0-2 mm, and >2-6 mm regions were significantly higher in diabetes group than in normal control group (all at P<0.05).The CD values in the anterior layer were higher in non-DR and DR groups than in normal control group, and the CD values and total CD values in the middle and posterior layers were higher in non-DR group than in normal control group and DR group, and the differences were statistically significant (all at P<0.05).The CD values in the 0-2 mm and >2-6 mm regions were significantly higher in non-DR group than in normal control group, and the CD value in the >6-10 mm annular region was significantly higher in non-DR group than in DR group and normal control group (all at P<0.05).Multivariate linear regression analysis showed that age and glycosylated hemoglobin (HbA1c) level were the main influencing factors for the increase in CD values in diabetic patients ( β=0.266, P<0.001; β=0.423, P=0.003). Conclusions:The decrease of corneal transparency precedes the appearance of DR in patients with diabetes.Poor control of HbA1c level in diabetic patients may cause the decline of corneal transparency.

Objective To observe the application effect of magnetic resonance imaging technology in evaluating the brain structure and function of patients with type 2 diabetic painful neuropathy (PDN). Methods Forty patients with type 2 diabetes mellitus hospitalized in our hospital were selected as the study objects, and were divided into diabetes mellitus (DM) group (n=12), peripheral neuropathy (DPN) group (n=14) and PDN group (n=14). General clinical biochemical indexes of three groups were analyzed. The structural brain and function of brain area in three groups were compared. Results Age, duration of diabetes, systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), free fatty acid (FFA), albumin (ALB), creatinine (Cr), uric acid (UA), estimated glomerular filtration rate (eGFR), cystatin C (Cys-C), total cholesterol (TC), triglyceride (TG) of the three groups were compared, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPO-Ab) and serum calcium (Ca) in the three groups showed no significant differences (P > 0.05). Compared with the DM group, the gray matter volume (GMV) in the DPN group was significantly decreased (P < 0.05). Compared with the DM group, amplitude of low frequency fluctuation (ALFF) and fractional amplitude of low frequency fluctuation (fALFF) of left medial superiorfrontal gyrus in the PDN group were significantly decreased (P < 0.05). Conclusion Abnormal GMV in the left angular gyrus in DPN patients may be associated with a higher risk of concomitant cognitive impairment. The decrease of ALFF in the right cerebellar vermis and fALFF in the left medial superior frontal gyrus in PDN patients may be related to the pathogenesis of pain.

Objective    To investigate the effect of simvastatin and mechanical pretreatment on intimal hyperplasia of venous graft and its mechanism. Methods    Twelve New Zealand rabbits were selected and randomly divided into 4 groups: a blank control group, a simvastatin topical treatment group, a mechanical precondition group and a combined group (n=3 in each group). Ultrasound was used to evaluate the changes of graft wall and blood flow velocity in the graft, and pathological section was used to evaluate the intimal hyperplasia. Human umbilical cord endodermal cells were cultured in vitro. A simvastatin group and a solvent control group were set to detect YAP phosphorylation, downstream target gene expression and cell proliferation. Results    Vascular ultrasound showed that except the simvastatin topical treatment group, the flow velocity in vein grafts in the other three groups significantly increased 21 days after surgery compared with 7 days after surgery (P<0.01). Pathological sections showed that the thickness of new intima in the simvastatin topical treatment group, mechanical precondition group, combined group and blank control group were 45.56±4.11 μm, 201.28±16.71 μm, 143.57±7.82 μm, 249.45±13.33 μm, respectively, and there were statistical differences compared with the blank control group (P<0.05). In vitro results showed that compared with the solvent control group, cell death was observed in high concentration simvastatin (5 mmol/L) group, cell proliferation was inhibited in low concentration simvastatin (2.5 mmol/L) group (P<0.05), the expression of YAP protein in the simvastatin group was unchanged, but the expression of phosphorylated YAP protein significantly increased (P<0.05), and the expression of downstream target gene ccn1 was down-regulated (P<0.001). Conclusion    Intravascular local application of simvastatin and mechanical preconditioning alone or in combination can inhibit intimal hyperplasia of venous graft. High concentration of simvastatin has cytotoxicity, while low concentration of simvastatin has inhibitory effect on cell proliferation. Simvastatin can inhibit the formation of new intima by inhibiting the entry of YAP into the nucleus and reducing the transcription of cell proliferation-related target gene ccn1.

【Objective】 To investigate the preventive effects of early apoptotic splenic mononuclear cells induced by extracorporeal photopheresis (ECP) on acute graft versus host disease (aGVHD) in mice and explore the underlying mechanisms. 【Methods】 1) Splenic mononuclear cells were extracted from C57BL/6 mice and treated with different concentrations of 8-MOP (50 ng/mL, 100 ng/mL, 200 ng/mL, 300 ng/mL, 600 ng/mL). After treatment, irradiate the cells with 2 J/cm² of ultraviolet light. Then, use the Annexin V-FITC/PI apoptosis detection kit to assess the early apoptosis rate of the cells and determine the optimal concentration of 8-MOP for the experiment.2) There were 35 SPF-grade female BALB/C mice (H-2Kd) aged 6-8 weeks. After whole-body irradiation with 8Gy X-rays, the mice were divided into five groups: sham irradiation group received intravenous infusion of 0.2 mL of normal saline, the syngeneic bone marrow transplantation group received intravenous infusion of 0.2 mL of BALB/C mouse bone marrow nucleated cell suspension (including a cell count of 1×10⁷), the allogeneic bone marrow transplantation group received intravenous infusion of 0.2 mL of C57BL/6 mouse bone marrow nucleated cell suspension (including a cell count of 1×10⁷), the aGVHD group received intravenous injection of a mixture of C57BL/6 mouse bone marrow nucleated cells (including a cell count of 1×10⁷) and splenic mononuclear cells (including a cell count of 1×10⁷) in 0.2 mL, the ECP prevention group received pre-transplant intravenous infusion of 0.2 mL of ECP-treated splenic mononuclear cells of C57BL/6 mice (including a cell count of 1×10⁷ ) 48 hours before transplantation, and on the day of transplantation, intravenous injection of a mixture of C57BL/6 mouse bone marrow nucleated cells (including a cell count of 1×10⁷) and splenic mononuclear cells (including a cell count of 1×10⁷ ) in 0.2 mL.The preventive effects of ECP on aGVHD were observed, and the concentrations of IFN-γ, IL-2, TNF, IL-4 and IL-6 in mouse serum were measured using CBA. Th1 cell counts were determined by flow cytometry. 【Results】 Different concentrations of 8-MOP (50 ng/mL,100 ng/mL, 200 ng/mL, 300 ng/mL, 600 ng/mL) were used to treat mouse splenic mononuclear cells. The early apoptosis rates (%), observed after treatment were as follows: (14.18±0.865) vs (16.76±0.407) vs (18.83±0.404) vs (19.27±0.404) vs (14.5±0.529). The appropriate concentration of 8-MOP was determined to be 200 ng/mL.In vivo experiment, the results showed that the aGVHD group had decreased survival rate, reduced body weight, and increased clinical scores compared to the syngeneic and allogeneic bone marrow transplantation groups (P<0.01), and the chimerism of bone marrow cells in mice after transplantation was over 90%. ECP significantly improved the survival rate of mice after transplantation, reduced clinical scores (P<0.05), and decreased the concentrations of Th1 cell cytokines in serum (P<0.05) and the counts of Th1 cells in the spleen (P<0.05). 【Conclusion】 ECP-induced early apoptotic single nuclear cells from the spleen can prevent the occurrence of aGVHD by reducing the Th1 response in mouse.
