ABSRACT The development of hepatocellular car-cinoma(HCC)is closely related to the formation of tumour blood vessels.VEGF-mediated angiogenesis is a major driver of the immune escape response in tumours.VEGF binds to vascular endothelial growth factor receptor2(VEGFR2)on endothelial cells,promoting endothelial cell proliferation and migration,inducing vascular changes in HCC,and thus promote the growth of hepatocellular carcino-ma cells.Anti-VEGF and its receptor-targeted mo-lecular drugs are currently effective new treat-ments for HCC.Monoclonal antibodies against VEGF and small-molecule tyrosine kinase inhibitors targeting VEGF have been shown to block its angio-genic activity,alleviate the inhibitory effect of the tumour microenvironment,and ultimately achieve tumour regression.This article provides a review of the research progress of VEGF/VEGFR inhibitors in HCC treatment.

Objective To investigate the correlation of neutrophil to high-density lipoprotein cho-lesterol ratio(NHR)and lipoprotein(a)[Lp(a)]with occurrence of acute ischemic stroke(AIS)in elderly patients with non-valvular atrial fibrillation(NVAF).Methods A total of 301 elderly NVAF patients admitted to Hefei First People's Hospital from May 2020 to May 2023 were en-rolled,and according to whether they were combined with AIS or not,they were divided into stroke group(143 cases)and non-stroke group(158 cases).Binary logistic regression analysis was used to screen risk factors,and ROC curve was plotted to assess their predictive values for AIS.Results Lp(a)and NHR in stroke group were significantly higher than those in non-stroke group,the difference was statistically significant(P＜0.01).Multivariate binary logistic regression analysis showed that NHR and Lp(a)were independent risk factors for death with NVAF com-bined AIS(OR=1.728,95％CI:1.367-2.186,P=0.000;OR=1.005,95％CI:1.002-1.007,P=0.000);ROC curve analysis indicated that the AUC value of NHR and Lp(a)in diagnosing AIS in NVAF patients was 0.668 and 0.735,respectively,and that of their combination was 0.789,which was significantly higher than that of NHR and Lp(a)alone(P＜0.01).Conclusion NHR and Lp(a)are independently related to AIS in NVAF patients,and their combination has certain diagnos-tic efficacy.

Objective To discuss the nursing cooperation method in CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue.Methods A total of 81 patients,who needed to receive pulmonary nodule localization before thoracoscopic resection,were enrolled in this study.The nursing cooperation measures,including the preparation and injection of indocyanine green combined with methylene blue,breathing mode coordination,position management,precise localization coordination,and psychological care,were analyzed.Results Successful nodule localization was accomplished in all patients.No statistically significant difference in the incidence of adverse events existed between the patients with different clinical characteristics(P＞0.05).The gender,age,lesion site,nodule size,nodule-pleura distance,posture during puncturing and needle path route were not the factors influencing the occurrence of adverse reactions in patients receiving CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue.Conclusion In performing CT-guided pulmonary nodule localization using indocyanine green combined with methylene blue,the nursing cooperation method carries generality and stability,which is suitable for patients with different clinical characteristics.
