RESUMEN
INTRODUCTION: The aim of the study was to evaluate the effects of blood pressure (BP) goals on cardiovascular outcomes in hypertensive patients. MATERIAL AND METHODS: Primary hypertensive patients were retrospectively enrolled from outpatient clinics. The demographics, comorbidities, laboratory parameters and glomerular filtration rate (GFR) were collected. All participants were followed for 1 year. Cardiovascular outcomes included composite of all-cause mortality, non-fatal myocardial infarction, and non-fatal ischemic stroke/transient ischemic attack. Adverse event was defined as falling down and GFR decrease at follow-up. RESULTS: A total of 1226 patients were included. Based on therapeutic BP goals, participants were divided into low (< 130/80 mm Hg) and high (< 140/90 mm Hg) therapeutic goal groups and an uncontrolled hypertension (≥ 140/90 mm Hg) group. Compared to the low therapeutic goal group, patients in the uncontrolled group were older and more likely to be smokers, have longer duration of hypertension, diabetes mellitus, lower GFR and higher prevalent ischemic stroke (p < 0.05). Patients in the uncontrolled hypertension group had higher incidence of composite endpoints than low and high therapeutic goal groups. Two cases of falling down were observed in the low therapeutic goal group and no significant changes in GFR were observed. With adjustment for confounding factors, the uncontrolled hypertension group had higher risk of composite endpoints compared to low and high therapeutic goal groups, and these benefits were more prominent in the low versus high therapeutic goal group. CONCLUSIONS: In hypertension patients, when compared to uncontrolled hypertension patients, low therapeutic BP goal is associated with better cardiovascular outcomes than high therapeutic BP goal.
RESUMEN
BACKGROUND: Lung squamous cell carcinoma (lung SCC) is a common type of malignancy. Its pathogenesis mechanism of tumor development is unclear. The aim of this study was to identify key genes for diagnosis biomarkers in lung SCC metastasis. METHODS: We searched and downloaded mRNA expression data and clinical data from The Cancer Genome Atlas (TCGA) database to identify differences in mRNA expression of primary tumor tissues from lung SCC with and without metastasis. Gene co-expression network analysis, protein-protein interaction (PPI) network, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and quantitative real-time polymerase chain reactions (qRT-PCR) were used to explore the biological functions of the identified dysregulated genes. RESULTS: Four hundred and eighty-two differentially expressed genes (DEGs) were identified between lung SCC with and without metastasis. Nineteen modules were identified in lung SCC through weighted gene co-expression network analysis (WGCNA). Twenty-three DEGs and 26 DEGs were significantly enriched in the respective pink and black module. KEGG pathway analysis displayed that 26 DEGs in the black module were significantly enriched in bile secretion pathway. Forty-nine DEGs in the two gene co-expression module were used to construct PPI network. CFTR in the black module was the hub protein, had the connectivity with 182 genes. The results of qRT-PCR displayed that FIGF, SFTPD, DYNLRB2 were significantly down-regulated in the tumor samples of lung SCC with metastasis and CFTR, SCGB3A2, SSTR1, SCTR, ROPN1L had the down-regulation tendency in lung SCC with metastasis compared to lung SCC without metastasis. CONCLUSIONS: The dysregulated genes including CFTR, SCTR and FIGF might be involved in the pathology of lung SCC metastasis and could be used as potential diagnosis biomarkers or therapeutic targets for lung SCC.
