OBJECTIVETo investigate the effect of functional blocking of endogenous miR-23a with a specific antisense oligonucleotide (ASO) on the proliferation and invasiveness of gastric adenocarcinoma cell line MGC803 in vitro.

METHODSA specific ASO targeting miR-23a, namely ASO-23a, was transfected into MGC803 cells to block endogenous miR-23a. The mRNA level of miR-23a in the transfected cells was detected with quantitative real-time PCR. The changes of cell proliferation following the transfection were detected with MTT assay and colony formation assay, and TUNEL assay and Transwell assay were employed to evaluate the changes in cell apoptosis and invasiveness, respectively.

RESULTSQuantitative real-time PCR demonstrated efficient functional blocking of endogenous miR-23a in MGC803 cells by ASO-23a. Suppression of miR-23a with ASO-23a obviously inhibited cell growth, colony formation and invasiveness of MGC803 cells and significantly enhanced the cell apoptosis.

CONCLUSIONASO-23a can efficiently block the function of endogenous miR-23a in MGC803 cells to inhibit cell proliferation and invasion and promote cell apoptosis.

Objective To study the relationship between serum UA level and early outcome in acute ischemic stroke (AIS) patients. Methods Four hundred and twenty-one AIS patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University from March 2015 to March 2016 were divided into good outcome group (n = 232) and poor outcome group (n = 189) according to their modified Rankin scale (mRS) score. Their demographic data, risk factors for vascular disease, laboratory testing parameters, imaging and clinical data and NIHSS score were recorded and compared. The relationship between serum UA level and early poor outcome in AIS patients was analyzed by unconditioned logistic regression analysis. Results The incidence of AF and cerebral infarction in the territory of anterior cerebral artey and middle cerebral artery, SBP, serum TC,LDL and urea levels,NIHSS and mRS score, and mortality were significantly higher and the hospital stay time was significantly longer while the serum UA level and GCS score were significantly lower in poor outcome group than in good outcome group (P＜0.05,P＜0.01). Unconditioned logistic regression analysis showed that SBP,NIHSS score and serum UA level were the major risk factors for the early poor outcome in AIS patients (OR = l.017,95％CI:1.003-1.031,P = 0.018;OR = 1.274,95％CI:1.178-1.378,P=0.000;OR=0.993,95％CI:0.989-0.996, P = 0.000). Conclusion The low serum UA level is related with the early poor outcome in AIS patients.

Objective:To investigate the relationship between the E2 and E4 alleles of apolipoprotein E (apoE) gene and myocardial infarction (MI) in type 2 diabetes Mellitus (T2DM) patients, and to explore the relationship between apoE polymorphism and blood lipid metabolism.Methods:This case control study was conducted from August 2016 to March 2020 in China-Japan Friendship Hospital, 3 459 inpatients with T2DM were included including 3 044 patients without MI (T2DM group) and 415 patients with MI (T2DM+MI group). Real time fluorescent quantitative PCR was used to detect apoE polymorphism. Automatic biochemical analyzer was used to detect lipid levels. Logistic regression analyses were performed to determine the association of apoE with risk of MI in patients with T2DM.Results:(1) The frequency of E4 allele in T2DM+MI group (12.29%, 102/830) was significantly higher than in T2DM group (9.13%,556/6 088), while the frequency of E2 allele in T2DM+MI group (7.35%,61/830) was significantly lower than that in T2DM group (8.21%,500/6 088), P=0.012. Logistic regression analyses showed that E4 allele carrier (E3/E4+E4/E4) faced a higher risk for MI in T2DM patients ( OR=1.48, 95% CI 1.14-1.92, P=0.003), while E2 allele carrier(E2/E3+E2/E2)did not face a higher risk of MI in T2DM patients ( OR=0.88, P=0.642). (2) The levels of apoE polymorphism and blood lipid: The levels of TC, LDL-C and apoB increased in the order of E4 allele, wild type and E2 allele ( P<0.05). The levels of HDL-C, apoA1 and apoE decreased in the order of E4 allele, Wild type and E2 allele ( P<0.05). Conclusion:The E4 allele is a risk factor for MI in T2DM patients, and apoE polymorphism can affect blood lipid level in this patent cohort.
