Tumors exhibit abnormal glucose metabolism, consuming excessive glucose and excreting lactate, which constructs a tumor microenvironment that facilitates cancer progression and disrupts immunotherapeutic efficacy. Currently, tumor glucose metabolic dysregulation to reshape the immunosuppressive microenvironment and enhance immunotherapy efficacy is emerging as an innovative therapeutic strategy. However, glucose metabolism modulators lack specificity and still face significant challenges in overcoming tumor delivery barriers, microenvironmental complexity, and metabolic heterogeneity, resulting in poor clinical benefit. Nanomedicines, with their ability to selectively target tumors or immune cells, respond to the tumor microenvironment, co-deliver multiple drugs, and facilitate combinatorial therapies, hold significant promise for enhancing immunotherapy through tumor glucose metabolic reprogramming. This review explores the complex interactions between tumor glucose metabolism-specifically metabolite transport, glycolysis processes, and lactate-and the immune microenvironment. We summarize how nanomedicine-mediated reprogramming of tumor glucose metabolism can enhance immunotherapy efficacy and outline the prospects and challenges in this field.

AIM: To investigate the possible use of anti-FGF-2 nanobody for the treatment of pathological neovascularization. METHODS: SD rats were divided into a sham operation group, a control group (3 mm diameter circular filter paper soaked with 1 mol/L NaOH solution was applied to the central part of the cornea of rats for 30 s to prepare the rat model of alkali-burn angiogenesis) and a treatment group (treated with a drop of 3 mg/mL anti-FGF-2 nanobody 7 days after the operation. Repeat application 3x/day for 14 days). Corneal angiogenesis was measured by stereoscopic microscopy and CD31 immunohistochemical staining. The mRNA and protein expression levels of VEGF and FGF-2 were detected by quantitative fluorescence PCR (qPCR), enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry.RESULTS: (1) Blood vessel: The area of the treatment group was significantly reduced compared with the model group, and the vascular lumen was narrower (P<0.05). The difference was the most significant after 14 days of drug intervention; (2) Expression level of FGF-2 mRNA and protein: the model group had similar results to the treatment group (P>0.05); (3) Expression levels of VEGF mRNA and protein: The treatment group was significantly higher than the model group (P<0.05). In addition, the expression of VEGF also increased significantly in the continuous administration of the sham operation group. CONCLUSION: Anti-FGF-2 nanobody can be used for the treatment of angiogenesis. However, the expressions of VEGF will compensatorily increase after blocking FGF-2 in normal or pathological rats.

AIM: To investigate the effect of ecdysterone (EDS) on H9c2 cardiomyocytes after oxidative stress.METHODS:H9c2 cells were cultured in vitro and divided into control group, high dose (2 μmol/L) of EDS group, middle dose (1.5 μmol/L) of EDS group, low dose (1 μmol/L) of EDS group, and H2O2 group.H9c2 cardio-myocytes in H 2 O2 group and high , middle and low doses of EDS groups were exposed to H 2 O2 for 6 h to establish the model of oxidative stress.The viability of the H9c2 cells was detected by CCK-8 assay.The apoptosis of H9c2 cells was analyzed by flow cytometry.The levels of lactate dehydogenase (LDH) and creatine kinase-MB (CK-MB) in the culture medium, and the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in the H9c2 cells were measured by colorime-try.The generation of reactive oxygen species (ROS) and the mitochondrial membrane potential were evaluated by flow cy-tometry and confocal laser scanning microscopy .The protein levels of Bax , Bcl-2 and cleaved caspase-3 in the H9c2 cells were determined by Western blot .RESULTS:Ecdysterone at the selected concentrations had no effect on the viability of H9c2 cells.Compared with control group, the levels of LDH, CK-MB, ROS and MDA, and the apoptotic rates of the H9c2 cells were significantly increased after treated with H 2 O2 , but were decreased by EDS treatment in a dose-dependent man-ner.The levels of SOD and mitochondrial membrane potential of the H 9c2 cells in H2 O2 group were reduced significantly compared with control group , but high, middle and low doses of EDS treatments up-regulated the levels of SOD and mito-chondrial membrane potential in H 2 O2-treated H9c2 cells.The protein levels of Bax and cleaved caspase-3 in the H9c2 cells in H2 O2 group showed significant elevation in comparison with control group , and the protein expression of Bcl-2 de-clined in H2 O2 group compared with control group , but high, middle and low doses of ecdysterone treatments down-regula-ted the protein levels of Bax , cleaved caspase-3 and up-regulated the expression of Bcl-2 in H2 O2-treated H9c2 cells. CONCLUSION:Ecdysterone attenuates the effect of H 2O2-induced oxidative stress on H9c2 cardiomyocytes.The mecha-nism may be involved in scavenging oxidative stress products , increasing antioxidant enzyme activity and improving mito-chondrial function .

Objective To explore clinical value of tumor specific growth factors (TSGF) in serum and bronchoalveolar lavage fluid (BALF) on differential diagnosis of benign and malignant periphery solitary pulmonary nodules (PSPN). Methods Serum and BALF from both normal and afflicted side were collected from 211 patients with PSPN(case group) and from 196 patients without any type of tumor (control group). TSGF and carcinoembry-onic antigen (CEA) in serum and BALF were measured in both groups. Results In the malignant PSPN patients, CEA in serum, normal and afflicted side were 28.73 (SD: 15.61) μg/L,63.31 (SD:21.28) μg/L and 85.54(SD: 26.19)μg/L,respectively, which was significantly higher than that of the benign PSPN patients (7.21(SD:2.43) μg/L, 12.36(SD:6.93)μg/L and 14.65 (SD:8.07)μg/L,respectively), as well as that of the control group (4.68 (SD: 1.25) μ/L and 11.06(SD:8.03) μg/L in serum and BALF, respectively (P < 0.05). TSGF in the serum and BALF from the normal and afflicted side of malignant PSPN patients was 88.73 (SD:13.51)μg/L, 110.73 (SD: 18.64) μg/L and 162.80(SD:58.89) μg/L, respectively, which were significantly higher than that of the benign PSPN patients (56.31(SD: 2.43) μg/L, 79.25 [SD: 36.86] and 86.29 (SD: 37.07) μg/L, respectively) (P <0.05). Furthermore, in the malignant PSPN patients, TSGF and CEA in the afflicted side were significantly higher than that of the normal side. Sensitivity, specificity and accuracy of TSGF in BALF from the afflicted side for malig-nant diagnosis were 86.6%,100.0% and 98.6%,respectively,which was higher than that of CEA (70.2% ,78. 9% and 76.5% respectively) and that of serum TSGF (73.1% ,88.9% and 85.7% respectively). Conclusions TSGF in bronchoalveolar lavage fluid and serum has a significant role in differential diagnosis of benign and malig-nant periphery solitary pulmonary nodules. Furthermore, measurement of TSGF in bilateral BALF is helpful in diag-nosis of tumor location.
