ObjectiveBy observing the effect of Qianyang Yuyin granules on the phenotype of renal tubule epithelial cells， the intervention of Qianyang Yuyin granule on renal interstitial fibrosis was investigated. MethodThe renal tubular epithelial cells （HK-2） were treated with different concentrations of transforming growth factor （TGF）-β₁ （5， 10， 15， 20， 25 μg·L^-1） for 24 hours， and cell morphology and growth state were observed with an inverted phase contrast microscope. The 20 μg·L^-1 was selected as the most appropriate concentration of TGF-β₁ according to Western blot results for subsequent experiments. HK-2 cells were divided into six groups： blank group， TGF-β₁ group （concentration of 20 μg·L^-1）， low， medium， and high dose Qianyang Yuyin granule groups （concentration of 0.5， 1， 2 g·L^-1）， and valsartan group （1 × 10^-5 mol·L^-1）. The cell activity was measured by cell proliferation and cell counting kit-8 （CCK-8）. The cell migration ability was detected by scratch test. The Transwell method was used to detect the invasiveness of cells. Western blot was used to detect levels of fibronectin （FN）， E-cadherin， α-smooth muscle activator （α-SMA）， Vimentin， collagen type Ⅰ（Col Ⅰ）， collagen type Ⅳ（Col Ⅳ）， and other related proteins. ResultTGF-β₁ stimulating epithelial-mesenchymal transition （EMT） in renal tubular epithelial cells was time- and concentration-dependent. Compared with the blank group， higher concentration in the TGF-β₁ group indicates longer intervention time and more obvious long spindle change of cells， and the migration and invasion ability of the cells was significantly enhanced. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ increased significantly （P<0.05， P<0.01）， while the expression level of E-cadherin protein decreased （P<0.05）. Compared with the TGF-β₁ group， Qianyang Yuyin granule groups could maintain normal cell morphology， and the migration and invasion ability of the cells was inhibited. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ decreased （P<0.05， P<0.01）， and the expression of E-cadherin protein was significantly restored （P<0.05）. ConclusionQianyang Yuyin granule can reverse TGF-β₁-induced interstitial transformation of renal tubular epithelial cells by reducing the phenotypic expression of mesenchymal cells and increasing the phenotypic expression of epithelial cells.

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 satisfaction levels of the rural elderly in Dafeng district of Yancheng, Jiangsu province with the contracted family doctor services, and to identify the factors that influence their satisfaction.The findings of this study will provide valuable insights for improving the quality of the contracted family doctor services offered to the rural elderly population.Methods:The study utilized the stratified cluster sampling method to select elderly individuals aged 60 years and above from Dafeng district, Yancheng city for a questionnaire survey.Specifically, the study focused on elderly individuals who had participated in contracted family doctor services for more than six months.The survey aimed to gather information on the elderly population's general situation, as well as their understanding, utilization, and satisfaction with contracted family doctor services.The satisfaction of contracted family doctor services was analyzed using the chi square test and multivariate Logistic regression to identify the influencing factors.Results:The study surveyed 385 elderly individuals from rural areas who had contracted family doctor services.The results showed that 88.3%(340/385)of respondents were satisfied with the services they received.Additionally, 99.2%(382/385)of those surveyed were aware of the contracted family doctor services, and 81.8%(315/385)had received basic medical services from their signed-up doctors.The results of a multifactor analysis that examined the factors influencing the overall satisfaction of elderly patients with their contracted family doctor services revealed several significant factors.Specifically, being female( OR=2.557, 95% CI: 1.122-5.830, P=0.026)and unmarried( OR=7.355, 95% CI: 1.850-29.237, P=0.005), supporting the contracted family doctor services system( OR=18.442, 95% CI: 1.732-195.973, P=0.016), believing that the contracted medical institutions had excellent hardware facilities( OR=9.918, 95% CI: 2.313-42.526, P=0.002)and providing high-quality health services for the elderly( OR=8.723, 95% CI: 1.556-48.908, P=0.014), as well as experiencing improved health status after signing the contract( OR=5.006, 95% CI: 1.764-14.201, P=0.002)were all significant factors influencing their satisfaction.These findings suggest that these factors are important considerations for improving the satisfaction of elderly patients with their contracted family doctor services. Conclusions:The contracted family doctor services provided in Dafeng district, Yancheng city have been well received by the rural elderly population.Factors such as gender, marital status, attitude towards the contracted family doctor services system, improvements in health status after contracting the service, quality of the hardware facilities at the contracted medical institution, and availability of health services specifically tailored for the elderly all play a role in determining the level of satisfaction among the contracted elderly population.To better serve the elderly population, it is crucial that we prioritize their needs.This can be achieved by improving the level of "suitable aging" in the contracted services and enhancing the satisfaction of family doctors who provide these services.
