Objective The aim of our study was to assess potential correlations between serum galectin‐3 concentrations and Ankylosing Spondylitis Disease Activity (ASDAS) index in patients with ankylosing spondylitis (AS). Methods A total of 112 patients with AS were included, and 130 healthy subjects were considered as controls. We collected the detailed medical history, and ASDAS index was used to assess the disease severity in patients with AS. Results The serum galectin concentrations were higher in AS patients compared to the health groups (14.1 ± 9.6 vs 9.2 ± 3.7, P

Pressure pipelines have been applied widely in the chemical industry, the petroleum enterprises and the electrical power plants. Leakage and explosion accidents happened frequently owing to the weakness of the pressure pipeline. To monitoring the pressure pipeline weakness, a novel method is presented by using optical FBG (FBG: Fiber Bragg Grating) sensors to carry on the real-time monitoring of the pressure piping surface strains. A typical pressure pipeline was fabricated with weak position of L shaped, Tee shaped and U shaped joints. The strains of the weak position were analyzed by the ANSYS software, and then the same weak positions were monitored by experimental method of FBG sensor. The FBG sensor was verified a feasible means to monitoring the pressure pipeline by comparing the ANSYS software results with the experimental results of FBG sensors.
