Objective:To explore the association between serum high density lipoprotein subtype 3 cholesterol (HDL3-C) levels and the severity and in-stent restenosis of patients with coronary artery disease.Methods:124 patients with coronary artery diseases and 62 healthy controls were included in this clinical case-control retrospective study. Participants were hospitalized from November 2020 to November 2021 at Jinling Hospital, Medical School of Nanjing University were enrolled. Patients with coronary artery disease were as follows: 28 patients with acute coronary syndrome and 96 patients with stable coronary heart disease. Serum HDL3-C levels as well as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were determined. According to the coronary artery angiography results of all patients at the time of admission, Gensini scores were calculated and patients were divided into in-stent restenosis group ( n=22), no in-stent stenosis group ( n=23) and non-stent implantation group ( n=79). The correlation between HDL3-C levels and other parameters was analyzed by Pearson or Spearman correlation analyses. Multivariate Logistic regression analyses were used to determine the impact of HDL3-C on the in-stent restenosis of coronary artery diseases. Results:Compared with controls, serum levels of HDL3-C and HDL-C were significantly decreased in patients with coronary artery diseases (all P<0.05). There was a significantly negative correlation between HDL3-C levels and Gensini scores ( r=-0.201, P=0.043). Among patients with coronary artery disease, serum levels of HDL3C, TC and TG in the in-stent restenosis group were significantly lower than in no in-stent stenosis group as well as than in the non-stent implantation group (all P<0.05). Multivariate Logistic regression analyses showed that after adjusting for age, sex, lipid-lowering drugs and TC, TG, LDLC parameters, HDL3-C ( OR=0.885, 95% CI 0.791-0.990, P=0.033) and HDL-C ( OR=0.018, 95% CI 0.001-0.426, P=0.013) levels were both independently associated with the occurrence of coronary artery disease; only HDL3-C levels (no in-stent stenosis group as the reference: OR=0.833, 95% CI 0.698-0.994, P=0.042; non-stent implantation group as the reference: OR=0.812, 95% CI 0.685-0.963, P=0.017) were independently associated with the presence of in-stent restenosis ( P<0.05). Conclusions:Serum HDL3-C levels are decreased in patients with coronary artery disease, especially in patients with in-stent restenosis. HDL3-C levels are associated with the severity of coronary artery lesions and the presence of in-stent restenosis of coronary arteries.

Objective : To investigate the expression , synergistic relationship and clinical significance of alcohol dehydrogenase (ADH1A) and vascular endothelial growth factor-A (VEGFA) in hepatocellular carcinoma (HCC) . Methods : The expression and correlation of ADH1A and VEGFA in HCC and adjacent normal tissues were ana lyzed by GEPIA . TCGA and GSEA were used to analyze the pathway of ADH1A in HCC . The clinical and patho logical data of 84 patients with HCC were collected , and 54 patients with paracancer normal tissue samples were se lected as controls to analyze the correlation between ADH1A and VEGFA and clinicopathological parameters of HCC . Immunohistochemistry was used to detect the protein expression of ADH1A and VEGFA in cases and con trols , and the correlation between the expression of ADH1A and VEGFA and the clinical progression and prognosis of patients with HCC was analyzed based on clinical pathological parameters and Kaplan Meier. Results : Bioinfor matics analysis found that ADH1A was low expressed in HCC and VEGFA was highly expressed in HCC , and there was a negative correlation between the two ( P < 0.001) ; immunohistochemical detection results showed that the expression of ADH1A in HCC tissue was lower than that in normal tissue adjacent to cancer (P < 0.01) while the expression rate of VEGFA in HCC tissue was significantly higher than that of normal tissue adjacent to cancer (P < 0.01) ; The recurrence rate of vascular thrombus and HCC patients in HCC group with high expression of ADH1A was lower (P < 0.05) . The proportion of tumor diameter > 5 cm , high TNM stage , microsatellite and G2 G3 dif ferentiation in HCC tissues in VEGFA high expression group was higher (P < 0.05) . Kaplan Meier survival analy sis showed that patients with high ADH1A expression and low VEGFA expression had a higher five year survival rate . Conclusion Low expression of ADH1A and high expression of VEGFA in tumor tissues of patients with HCC indicate tumor progression and can be used as one of the prognostic evaluation indicators for patients with HCC .
