Primary biliary cholangitis (PBC) is characterized as interlobular bile duct injury and fibrosis, which results from the loss of tolerance to self‐antigens. However, the exact pathologic mechanism leading to injury and fibrosis in PBC patients is not fully understood. Therefore, in this study, we examined the role of the T cell subsets in PBC patients and healthy controls (HCs). A higher number of invariant Natual killer T (iNKT) cells as well as CD3+CD56+αGalcer‐CD1d tetramer–T cells were found in patients with PBC compared with HCs. Moreover, these 2 T subpopulations produced significantly higher levels of Interleukin (IL)‐17A in PBC patients than those in in HCs, which has also been positively correlated with the disease severity. Furthermore, the level of IL‐17A produced by these 2 subpopulations was increased after stimulation of the autoantibodies in patients with PBC. Also, the elevated IL‐17A levels promoted the PBC‐related fibrosis, thus presenting a change in frequencies and functions of these cell phenotypes in the deterioration of the duct damage‐related fibrosis. This study clarified PBC patients’ distinct T subpopulations characteristics, providing evidence‐based diagnostic and therapies for these patients. The correlation between unclassical T subsets and IL‐17A may provide a novel target for the immunotherapy of PBC. Since IL‐17A was produced by invariant natural killer T cells and CD3+CD56+αGalcer‐CD1d tetramer‐T cells promote PBC‐related fibrosis, they could be potentially used as a novel target for immunotherapy in the patients with primary biliary cholangitis.

ABSTRACTGastric cancer (GC) is one of the serious malignant diseases, accounting for several cases globally. The prevention, discovery and cure of GC depend on its molecular mechanism. In recent decades, it has been increasingly recognized that the long noncoding RNAs (lncRNAs) have been involved in GC progression. Therefore, the present study is aimed at identifying relevant lncRNAs that could act as biomarkers for GC prognosis. LncRNA HOXA10-AS is identified to be highly expressed in GC using the ENCORI database. Kaplan-Meier plot analysis indicated that the survival rate of the patient is associated with the expression of lncRNA HOXA10-AS. Interference of HOXA10-AS inhibited GC cell proliferation, migration, and invasion as well as facilitated GC apoptosis. The targets of HOXA10-AS included miR-6509-5p and Y-box binding protein 1 (YBX1). Specifically, HOXA10-AS downregulated miR-6509-5p in GC. An increase of miR-6509-5p inhibited GC cell growth. Meanwhile, miR-6509-5p interacted with YBX1 in GC. Together, lncRNA HOXA10-AS potentially acted as an oncogene through the lncRNA HOXA10-AS/miR-6509-5p/YBX1 signaling pathway in GC.

Let Rbe a 2-torsion-free commutative ring with unity, Xa locally finite pre-ordered set with a finite number of connected components and I(X,R)the incidence algebra of Xover R. In this paper, we give a sufficient and necessary condition for a commuting map on I(X,R)to be proper.

The effect of adding small amounts of high strain hybrid components on the impact resistance of graphite epoxy composites subjected to projectiles traveling at ballistic velocities (greater than 900 ft/sec) has been studied. The hybrid components tested include superelastic shape memory alloy (SMA) and a high performance extended chain polyethylene (ECPE) known as Spectram. In all cases, the embedded SMA fibers were pulled through the graphite without straining to their full potential. It is believed that this is due to high strain rate effects coupled with a strain mismatch between the tough SMA and the brittle epoxy resin. However, a significant increase in energy absorption was found by adding ECPE and ECPE/SMA layers to the backface of the composite.
