The platelets play the important role in tumor angiogenesis, growth, and metastasis, in addition to coagulation. The interaction between tumors and platelets can produce "tumor-induced platelets", which leads various changes of platelet characteristics. In addition, activated platelets can also inhibit the effects of both chemotherapy and immunotherapy, therefore, both inhibiting platelet activation and depleting platelets can effectively improve tumor prognosis. In this review, we introduced the key role of platelets in the development of tumors, summarized their application in tumor diagnosis, monitoring, and treatment, and provided our view on how to develop precise delivery strategies based on platelets for achieve efficient and safe tumor treatment.

The immunosuppressive tumor microenvironment significantly limits the efficacy of immunotherapy. Tumor-associated macrophages (TAMs), the most abundant immune cells in the tumor microenvironment, often exhibit an immunosuppressive M2 phenotype, contributing to this immunosuppressive landscape. Modulating TAMs to adopt anti-tumor phenotypes can enhance immunotherapy outcomes and inhibit tumor progression.In recent years, tumor immunotherapy leveraging engineered bacteria has garnered considerable attention. Bacteria possess the ability to target tumors, preferentially colonizing tumor regions, and contain abundant pathogen-associated molecular patterns that effectively activate TAMs within the immunosuppressive tumor environment. This activation enhances the tumoricidal and clearance capabilities of TAMs. With the rapid advancements in synthetic biology, engineered bacteria have emerged as a potent therapeutic modality for immunotherapy, leading to increased focus on the regulation of TAMs by engineered bacteria.This paper first outlines clinical studies on targeted TAMs therapy and engineered bacteria-based tumor therapy. It then reviews recent advancements in bacterial regulation of TAMs, detailing how engineered bacteria enhance TAM recruitment, improve TAM phagocytosis, and remodel TAM phenotypes. Modulating TAMs with engineered bacteria presents a promising therapeutic strategy and introduces a novel approach in tumor immunotherapy.

AIM: To investigate the antiviral efficacy and mechanism of Qingre Xiaoyanning (QRXYN) in vivo, and provide experimental basis for their prevention and treatment of influenza A virus. METHODS: We constructed a mouse model infected with influenza A H3N2 virus. To evaluate the therapeutic effect of QRXYN on influenza A virus, we measured the body weight changes, pathological changes in lung tissue, hemagglutination titer, and viral load in mouse. To evaluate the possible mechanism of QRXYN's anti influenza A virus infection, we used the ELISA to measure the levels of TNF-α, IL-1β, IL-4, IFN-γ, and vascular cell adhesion molecule-1 (VCAM-1) in mouse bronchoalveolar lavage fluid; used flow cytometry to assess the proportions of macrophages (F4/80), helper T lymphocytes (CD4+ T lymphocytes), and natural killer (NK) cells in lung tissue; and used Western blotting to detect the expression of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MYD88), inhibitor of kappa B kinase-β (IKK-β), NF-kappa-B inhibitor alpha (IκBα), and phospho-IKB alpha (p-IκBα) in lung tissue. RESULTS: Compared to the model group, both Oseltamivir and QRXYN can alleviate the severity of lung tissue lesions in mice, decrease the blood coagulation titer and viral load of mouse lung tissue (P<0.01), lower the levels of TNF-α, IL-4, and VCAM-1 in bronchoalveolar lavage fluid (P<0.05, P<0.01), reduce the proportion of macrophages (P<0.05, P<0.01), and increase the proportion of CD4+T lymphocytes and NK cells (P<0.05, P<0.01). Additionally, oseltamivir can reduce the expression of MYD88 protein in mouse lungs (P<0.05), while QRXYN can decrease the expression of IKK-β and P-IκBα proteins in mouse lungs (P<0.05). CONCLUSION: QRXYN have good in vivo antiviral effects against the influenza A virus, and their mechanism may be related to the regulation of the immunologic function and NF-κB signal pathway.

AIM: To research the regulatory effects of Butein on lipid deposition and inflammation in non-alcoholic steatohepatitis (NASH). METHODS: HepG2 cells were divided into solvent control group (1‰ dimethyl sulfoxide) and different concentration of Butein groups (1, 3, 6, 12, 25, 50 μmol/L). The survival rate of HepG2 cells were detected, the low and high concentration groups of butein were determined. HepG2 cells were divided into solvent control group (1‰ DMSO), model group (induction with 1 mmol/L free fatty acids in vitro), low and high concentration of Butein groups. After 24 hours’ cell culture in each group, expression of triglyceride (TG), lipid synthesis-related factors SREBP-1c, FAS, SCD-1, lipid oxidation-related factors PPARα, CPT1A, MLYCD, and inflammatory factors TNF-α and MCP-1 in each group were detected. The model of NASH was constructed on C57BL/6J mouse by methionine choline deficiency diet (MCD). Normal diet group (ND group), model group (MCD group), low dose (100 mg·kg-1·d-1) and high dose (200 mg·kg-1·d-1) of Butein groups were established. After 4 weeks of feeding, pathological changes of liver tissues in each group were observed, contents of liver and serum TG and TC in each group were detected, and protein expression levels of lipid synthesis-related factors SREBP-1c, FAS, SCD-1 and lipid oxidation-related factors PPARα, CPT1A,  ACOX1 and MLYCD, inflammatory factors TNF-α and MCP-1in liver tissues were detected. RESULTS: Compared with solvent control group, Butein inhibited HepG2 cell growth when the concentration was ≥12 μmol/L (P<0.05). Make 5 and 10 μmol/L as low and high concentration groups, respectively. Compared with the solvent control group, the intracellular TG content of HepG2 cells in butein group was significantly lower (P<0.05). Compared with the model group, mRNA expressions of SREBP-1c, FAS, and SCD-1 was significantly lower (P<0.05), while mRNA expression of PPARα, CPT1A, and MLYCD was significantly higher (P<0.05), mRNA expression of TNF-α, MCP-1 was significantly decreased (P<0.05) in high-concentration butein group. Compared with the model group, the expression of SREBP-1c, FAS, SCD-1, MCP-1, TNF-α protein decreased and the expression of PPARα, CPT1A, MLYCD protein increased in the high concentration group. Compared with ND group, liver histological sections of MCD group showed obvious fat accumulation and inflammatory cell infiltration. Compared with the MCD group, the pathological manifestations of fat accumulation and inflammatory cell infiltration in the liver tissue of the butein groups were significantly improved, and the contents of TG and TC in the liver tissue of the butein groups were significantly decreased (P<0.05), while the protein expressions of PPARα, CPT1A, ACOX1, MLYCD were increased, and the protein expressions of SREBP-1c, FAS, SCD-1, TNF-α and MCP-1 were decreased in butein groups. CONCLUSION: Butein can improve lipid deposition and inflammation in NASH livers. Its mechanism may be to reduce the expression of lipid synthesis-related factors, enhance the expression of lipid oxidation-related factors, and reduce the expression level of inflammatory factors.

AIM: To investigate the involvement of HIF-1α/VEGF regulation in its anti-angiogenesis effects using adjuvant-induced arthritis (AIA) rats. METHODS: AIA rats were orally treated by QLY extract for 24 days. After sacrifice, the joints were subjected to histological examination, while the blood was used in ELISA or biochemical tests. In addition, HUVEC cells were treated by QLY in vitro. MTT, wound-healing and tube-formation experiments were then  performed. Expression of some relevant proteins in cells were investigated.RESULTS: Compared to the healthy controls, obvious synovial invasion and angiogenesis occurred in AIA rats. Blood levels of HIF-1ɑ, VEGF, PDGF, and TGF-β1 were increased, while the ratio of MDA/SOD was decreased a lot. After QLY treatment, all these abnormalities were attenuated. In vitro experiments, QLY showed notable potentials in inhibiting proliferation, migration and tube-constructing abilities of HUVEC cells. Furthermore, it suppressed the expression of p-MEK/MEK and p-ERK/ERK. CONCLUSION: QLY can reduce the pathological functions of vascular endothelial cells by inhibiting HIF-1α/VEGF, and it consequently eased AIA-related abnormal angiogenesis in AIA rats' joints.

AIM: To examine the impact of the transcription factor 7 analogue 2 (TCF7L2) gene polymorphism on the hypoglycaemic effect of exenatide in patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 100 newly diagnosed Han Chinese patients with T2DM who had not received any drug treatment were selected from the Affiliated Hospital of Xuzhou Medical University and treated with exenatide monotherapy for 6 months. The TCF7L2 rs290487 was genotyped by SnaPshot method, and blood glucose levels, lipids profiles and pancreatic function evaluation indicators were measured at baseline, 3 months and 6 months after exenatide treatment. Multiple linear regression analysis was employed to assess the correlation between each indicator and the reduction in glycated hemoglobin (HbA1c) levels after 6 months of exenatide treatment. The expression of TCF7L2 protein in the plasma of T2DM patients was detected by enzyme-linked immunosorbent assay (ELISA) kit. Furthermore, western blotting was conducted to ascertain TCF7L2 expression in pancreatic tissues obtained from db/db mice and INS-1 cells cultured under high glucose conditions. Lentivirus transfection was used to overexpress or knock down TCF7L2 in insulinoma cell line (INS-1) cells, followed by measurement of KSIS activity and insulin content after a 24-hour intervention with exenatide. RESULTS: The distribution pattern of TCF7L2 rs290487 was found to be in accordance with Hardy-Weinberg equilibrium (P>0.05). Following 6 months of exenatide treatment, there was a notable reduction in blood glucose levels and an improvement in lipid profiles when compared to baseline values. Additionally, there was a significant increase in the homeostasis model assessment of beta-cell function (HOMA-B) values. Patients with the TT genotype exhibited significantly lower postprandial plasma glucose (PPG) levels and HbA1c values compared to those with the CC or CT genotypes (P<0.05). After adjusting for age, gender, body mass index (BMI), and waist to hip ratio (WHR) in the multiple linear regression model, a significant association was observed between the rs290487 TT genotype, baseline HbA1c levels, and family history of diabetes with the reduction in HbA1c after six months of exenatide treatment (P<0.05). Furthermore, individuals with the rs290487 TT genotype demonstrated a notable elevation in TCF7L2 expression in plasma among T2DM patients in comparison to those with the CC genotype (P<0.05). In particular, pancreatic tissue from db/db mice exhibited markedly elevated TCF7L2 expression compared to [db/][m] mice. However, this up-regulation was reversed by exenatide treatment. Similarly, INS-1 cells cultured under high glucose conditions demonstrated an increase in TCF7L2 expression, which was ameliorated upon exenatide administration. The knockdown of TCF7L2 using shRNA enhanced the KSIS function of pancreatic β cells and augmented the insulinotropic effect of exenatide. Conversely, the upregulation of TCF7L2 impaired the KSIS function of pancreatic β cells and attenuated the insulinotropic effect of exenatide. CONCLUSION: The TCF7L2 rs290487 gene polymorphism is closely associated with the hypoglycaemic efficacy of exenatide therapy. The risk allele C may diminish the effectiveness of exenatide by impacting the levels of PPG and HbA1c in T2DM patients. The mutation at TCF7L2 rs290487 site (C→T) influenced the expression of TCF7L2 protein. By exerting its regulatory effect, exenatide may be capable of regulating the impact of TCF7L2 on the function of pancreatic β cells.
