Objective:To investigate the tumor perfusion enhancement induced by low intensity ultrasound stimulated microbubble cavitation (USMC) combined with programmed cell death-Ligand 1(PD-L1) antibody on improving the immune microenvironment of solid tumors.Methods:Tumor-bearing mice were divided into 4 groups: Control ( n=26) group, USMC ( n=27) group, anti-PD-L1 ( n=27) group and USMC+ anti-PD-L1 ( n=27) group. USMC treatment was performed with a VINNO 70 ultrasound theranostics system. Tumor perfusion was evaluated by contrast-enhanced ultrasound (CEUS). The anti-tumor efficacy was assessed by the tumor growth curve and the survival time of mice. The number and function of CD8 + T cells, the differentiation of CD4 + T cells, the proportion of MDSC and the phenotype distribution of TAM in tumors were analyzed by flow cytometry. The content of CXCL9, CXCL10 and HIF-1α in tumor were detected by ELISA. The expression of VEGF in tumor tissues was analyzed by immunofluorescence. Results:CEUS showed that the values of PI and AUC of tumors were significantly increased after USMC compared with before USMC (all P<0.05). USMC combined with anti-PD-L1 therapy did suppress the tumor progression. FCM showed the number, the expression of proliferation antigen Ki67, the secretion of IFN-γ and Granzyme B of CD8 + T cells in tumors were higher in combined group than those in other three groups after therapy (all P<0.05). Meantime, the proportion of Th1 was rose while Tregs and MDSC were declined and the polarization of TAM was toward M1 type by combined therapy. ELISA analysis showed that the combined therapy also increased the concentration of CXCL9, CXCL10 and decreased the content of HIF-1α in tumors (all P<0.05). Meanwhile, the immunofluorescence expression of VEGF was significantly lower in combined group than that in the control group after treatment ( P<0.05). Conclusions:Tumor perfusion enhancement by USMC combined with PD-L1 antibody therapy could improve tumor immune microenvironment and USMC might be a novel effective method for potentiating PD-L1 antibody immunotherapy.

Evaluation value of atherogenic index of plasma for long-term prognosis of coronary artery disease / 中国医师杂志

Objective:To determine the predictive value of atherogenic index of plasma (AIP) on the long-term prognosis of patients with coronary artery disease (CAD).Methods:A total of 2 500 patients with coronary heart disease who underwent coronary angiography in Affiliated Hospital of Jining Medical University from May 2013 to November 2015 were retrospectively analyzed. According to the AIP value, the subjects were divided into low AIP group (AIP<0.06) and high AIP group (AIP≥0.06). The incidence of major adverse cardiovascular events (MACE) was compared between the two groups. Kaplan-meier method was used to evaluate the MACE-free survival rate, and multivariate Cox survival analysis was used to evaluate the independent predictors of MACE.Results:A total of 2 427 patients were followed up, with a follow-up rate of 97.08% and a median follow-up time of 4.29 years. There were 1 123 cases in the low AIP group and 1 304 cases in the high AIP group, among which 624 patients (25.7%) had MACE. The total incidence of MACE in the high AIP group was higher than that in the low AIP group ( HR=1.43, 95% CI: 1.22-1.68, P<0.01). Kaplan-meier curves showed that the MACE-free survival rate was significantly lower in the high AIP group ( P<0.01). After adjusting for multiple confounding factors, AIP was still associated with the prognosis of CHD patients. Increased AIP (≥0.06) was an independent predictor of MACE in CHD patients within 4 years ( HR=1.34, 95% CI: 1.14-1.58, P<0.01). Conclusions:AIP (≥0.06) was an independent predictor of MACE occurrence in patients with CAD within 4 years. AIP has a certain value in the long-term prognosis of patients with CAD.

Screening of lipid parameters in coronary artery disease based on LASSO regression / 中国综合临床

Objective:Using lasso regression analysis to screen out the blood lipid indexes closely related to coronary heart diseaseMethods:The clinical data of 3 062 patients with coronary heart disease who were hospitalized in the Department of Cardiology, Affiliated Hospital of Jining Medical College from May 2013 to November 2015 were retrospectively analyzed.They were divided into control group ( n=2 427) and coronary angiography group ( n=635). R language was used for statistical analysis.Multiple logistic regression models were established for indicators of blood lipid related to CAD, and their multicollinearity severity was assessed.LASSO regression was used to screen out the representative lipid parameters in the CAD prediction model. Results:A total of 3 062 patients were enrolled, including 2 427 patients in coronary heart disease group and 635 patients in control group.The inclusion of lipid parameters into multiple logistic regression model leads to serious multicollinearity.Stepwise regression can only partially reduce multicollinearity severity, while LASSO regression model significantly reduces multicollinearity severity.Low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) were found to be the representative lipid indexes for predicting coronary heart disease by LASSO regression analysis.Conclusion:LASSO regression has advantages in processing multicollinearity data.LASSO regression showed that LDL-C, HDL-C and non-HDL-C were representative lipid indicators for predicting coronary heart disease..
