05). In the normal 25-(OH) D group, levels of inflammatory factors and oxidative stress factor were lower than those in the abnormal 25-(OH) D group (P less then 0.05), while the SOD level, total antioxidant capacity and T cell subset counts were higher than those in the abnormal 25-(OH) D group (P less then 0.05). Moreover, the 25-(OH) D level in patients with autoimmune hepatitis was negatively correlated with hs-CRP, tumor necrosis factor-α (TNF-α), ALT and MDA, but positively correlated with CD3+ and CD4+ counts, SOD and total antioxidant capacity. Patients with autoimmune hepatitis, especially those with decreased level of vitamin D, are more prone to enhanced inflammatory and stress responses, decreased levels of T cell subsets and decline in immunity.

A total of 971 patients with coronary heart disease who were hospitalized and underwent PCI from April 2016 to May 2017 were studied. All 971 patients were divided into three subgroups according to CYP2C19 gene types as fast metabolizing, slow metabolizing and very slow metabolizing type. Patients were also classified according to the oral antiplatelet aggregation drugs they received clopidogrel group and ticagrelor group. The incidence of major adverse cardiac events (MACE) and bleeding events in the clopidogrel-treated and ticagrelor-treated groups and in patients with fast, slow, and very slow CYP2C19 metabolisms were compared. Binary logistic regression analysis was carried out to analyze the risk factors associated with MACEs and hemorrhagic ev2C19 genotyping may be used to provide guidance to optimize individual antiplatelet treatment.

A total of 27 children with 35 lesions with oropharyngeal low-flow venous malformation were included. The subjects were randomly divided into Groups A (13 patients with 16 lesions, treated with 3% polidocanol foam sclerosing agent) and B (14 patients with 19 lesions, treated with pingyangmycin + dexamethasone), respectively. The clinical efficacies and adverse reactions were analyzed and compared between these two groups. The average number of treatment times for Group A was 2.45±0.6, with an efficacy rate of 87.50%, while the average number of treatment times for Group B was 2.07±0.4, with an efficacy rate of 84.21%. No significant difference was found in the average treatment times or efficacy rates between Groups A and B. In addition, the adverse reaction incidence for Groups A and B were 38.46 and 14.29%, respectively, with statistically significant differences between these two groups. The combination of pingyangmycin and dexamethasone was safe and effective in treating children with oropharyngeal low-flow venous malformation, with fewer adverse reactions and is worthy of clinical promotion.

A total of 64 patients with new-onset diabetes (>6 m, A p.G40S was present in patients with type 2 DM (T2DM); the locus is associated with T2DM susceptibility in China. An LIPC frameshift mutation was identified, which had not been previously reported; the gene was found to markedly affect protein function and be associated with glucose and lipid metabolism. It was concluded that children with antibody-negative T1D have monogenic diabetes. The present findings shed light on the etiology and mechanism of antibody-negative diabetes, which will enable the comprehensive analysis of antibody-negative diabetes genotypes and phenotypes and further help improved precision treatment.

Ultrasound-targeted microbubble destruction (UTMD)-mediated gene transfection has been considered a useful tool for improving cancer treatment. see more The present study aimed to investigate the role of miR-767 in non-small cell lung cancer (NSCLC) and further analyze the effects of UTMD-mediated miR-767 inhibition on tumor progression. The expression of miR-767 was measured by reverse transcription-quantitative PCR. UTMD-mediated miR-767 inhibition was achieved by the co-transfection of microbubbles and miR-767 inhibitor in NSCLC cells. Cell proliferation was assessed by a CCK-8 assay and cell migration and invasion were examined by a Transwell assay. The expression of miR-767 was increased in NSCLC serum, tissues and cells compared with controls. The reduction of miR-767 in NSCLC cells led to the inhibition of cell proliferation, migration and invasion. UTMD increased the transfection efficiency of the miR-767 inhibitor in NSCLC cells, and UTMD-mediated miR-767 inhibition resulted in a more significant suppressive effect on tumor cell proliferation, migration and invasion. Taken together, the results indicated that miR-767 expression is upregulated in both NSCLC clinical samples and cells. The downregulation of miR-767 can inhibit tumor cell proliferation, migration and invasion, and these effects are further promoted by UTMD-mediated miR-767 inhibition, which indicated the potential of a UTMD-mediated miR-767 inhibition as a novel therapeutic strategy for NSCLC treatment.

In the present study, the role of miR-25 in PDAC cell proliferation was investigated. Upregulated expression of miR-25 was found in PDAC tissues and cell lines by reverse transcription-quantitative PCR. Cell proliferation was significantly enhanced by overexpression of miR-25 as shown by CCK-8 assay results. Meanwhile, overexpression of miR-25 also promoted G1-to-S phase transition of the cell cycle in Aspc-1 cells via flow cytometry analysis. However downregulation of miR-25 inhibited the tumor cell proliferation and cell cycle transition. Online software was used to predict the target gene for miR-25 and luciferase reporter assay confirmed that Abl interactor 2 (ABI2) was a target of miR-25 via direct binding of its 3′ untranslated region with miR-25. Moreover, results of the western blot analysis demonstrated that miR-25 negatively regulated the expression of ABI2 at the protein level.
