A rapid clinical diagnosis may efficiently improve the survival rate and prognosis of patients with ischemic heart disease (IHD). Therefore, a one-step, rapid and inexpensive analysis for the quick diagnosis of IHD was investigated in the present study. Consecutive patients who were subjected to myoglobin, cardiac troponin I and creatine kinase-MB isoenzyme assessment at the Emergency Department of Shenzhen Second People's Hospital (Shenzhen, China) between December 2017 and March 2018 prior to treatment were screened. Clinically applicable disposable strips were employed for quantification of the cardiac biomarkers. The analytical performance of the strips was evaluated by receiver operating characteristic (ROC) curves and compared with the traditional chemiluminescence immunoassay (CLIA) method. The data of 391 participants were collected. At the baseline, 57 patients were diagnosed with IHD and 334 patients were diagnosed with other diseases. The area under the ROC curve (AUC) of the CLIA model was 0.787 (95% CI, 0.709-0.865) with a specificity of 76.7% and a sensitivity of 71.9%. At the optimal cutoff value of -1.867, the negative and the positive predictive value were 94.1 and 34.5%, respectively. The AUC of the disposable strip model was 0.792 (95% CI, 0.729-0.855). At the cutoff value of -1.820 or below, the negative predictive value was 94.9%, the positive predictive value was 28.9%, the specificity was 66.8% and the sensitivity was 79.0%. The P-value of the ROCs was 0.858, indicating no statistically significant difference between the two assay methods. The cost of the disposable strip was 50% of that of the CLIA method and it took only 25% of the time that was required for the quantification of the three cardiac markers by CLIA. In conclusion, the disposable strip provides a platform for point-of-care testing and may be an easy, rapid, reliable and cost-saving method for the diagnosis of IHD.Osteoarthritis (OA) is a disorder of diarthrodial joints that can have multiple causes. Long non-coding RNAs (lncRNAs) participate in multiple diseases, including OA. It has recently been reported that the lncRNA microRNA 4435-2HG (MIR4435-2HG) is downregulated in OA tissues; however, the biological role of MIR4435-2HG during OA progression remains unclear. In the present study, interleukin (IL)-1β was used to establish an in vitro model of OA. Protein expressions of matrix metallopeptidase (MMP) 1, MMP13, collagen II, interleukin (IL)-17A, p65, phosphorylated (p)-p65, IκB and p-IκB in CHON-001 cells were detected by western blotting. Gene expressions of IL-17A, MIR4435-2HG and miR-510-3p in tissues or CHON-001 cells were measured by reverse transcription-quantitative PCR and western blotting, respectively. Cell Counting Kit-8 assay and immunofluorescence staining were used to investigate cell proliferation, and cell apoptosis was detected by flow cytometry. The association between MIR4435-2HG, miR-510-3p and IL-17A was investigated using the dual luciferase report assay. MIR4435-2HG and miR-510-3p overexpression were transfected into CHON-001 cells. The results demonstrated that miR4435-2HG overexpression significantly increased proliferation and inhibited apoptosis of CHON-001 cells. In addition, miR-510-3p was identified as the downstream target of MIR4435-2HG, and miR-510-3p directly targeted IL-17A. The results from the present study suggested that MIR4435-2HG could mediate the progression of OA by inactivating the NF-κB signaling pathway. In addition, miR4435-2HG overexpression inhibited OA progression, suggesting that miR4435-2HG may be considered as a potential therapeutic target in OA.The aim of the present study was to investigate the role of Smad3 inhibitors and the pyroptosis pathway in spinal cord injury, and to determine the underlying mechanism. The pyroptosis signaling pathway may be involved in spinal cord injury during the recovery period. Smad3 inhibitor may serve a role in alleviating spinal cord injury by reducing the pyroptosis of neurons, which is induced by caspase-1, absent in melanoma-2 or NOD-like receptors protein-1 during the recovery period of spinal cord injury. In the present study, spinal cord injury was alleviated by caspase-1 and Smad3 inhibitors. Therefore, a Smad3 inhibitor could relieve spinal cord injury in mice by directly downregulating caspase-1 and reducing neuron pyroptosis following spinal cord injury during the recovery period.Infantile haemangioma (IH) is a benign vascular tumour type that occurs in 3-10% of infants. In the present meta-analysis, previous studies comparing clinical outcomes, including the recovery rate and haemangioma activity score (HAS), adverse effects and relapse rates, were compared between patients treated with atenolol and those treated with propranolol for IH. A systematic search in various databases, including Medline, Cochrane Controlled Register of Trials, ScienceDirect and Google Scholar from inception until July 2019 was performed. The Cochrane risk of bias tool was used to assess the quality of published trials. A meta-analysis with a random-effects model and reported pooled mean differences (MD) or odds ratios (OR) with 95% CIs was performed. In total, 8 studies including 608 participants were analyzed. Only 2 studies were randomized controlled trials, while the majority of studies had low or unclear bias risks. Except for the response to medication (pooled OR=1.49; 95% CI, 0.85-2.18), all other outcomes (HAS, adverse reactions and relapse rate) were better for the atenolol group than the propranolol group. Atenolol resulted in better HAS (pooled MD=0.16; 95% CI, -0.42 to 0.73). Propranolol had more adverse reactions (pooled OR=2.17; 95% CI, 0.93-5.06) and a higher relapse rate (pooled OR, 1.67; 95% CI, 0.44-6.41) when compared to atenolol. read more However, these findings were not statistically significant. The results of this analysis suggest that atenolol may be non-inferior to propranolol and may offer advantages, including lower adverse reactions and relapse rates.Based on its pathological characteristics, breast cancer is a highly heterogeneous disease. Triple negative breast cancer (TNBC) is an aggressive subtype, and due to a lack of effective therapeutic targets, patients with TNBC do not significantly benefit from endocrine or anti-HER2 therapy. Conventional chemotherapy has been regarded as the only systemic therapy option for TNBC, but its therapeutic efficacy remains limited. Estrogen receptor β (ERβ) has been identified as a tumor suppressor in TNBC. Therefore, the aim of the present study was to identify the role of ERβ in regulating the response to chemotherapy, and to investigate its underlying mechanism in TNBC. MDA-MB-231 and BT549 cells were treated with doxorubicin (DOX), liquiritigenin [Liq, (Chengdu Biopurify Phytochemicals, Ltd.); a specific ERβ agonist], or a combination of DOX and Liq in vitro. The effects of various treatments on cell viability and proliferation were measured using the Cell Counting Kit-8 and colony-formation assays, respectively.
