Cerebral ischemic injury induces proliferation of NSCs, some of which will differentiate into both astroglia and neurons. EA may promote cells proliferation, stimulate the proliferating cells to differentiate into astroglia and mature into neurons, which may be one of the important reasons why EA can alleviate neurological deficits.

The activation of the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) pathway has been implicated as a key mediator in the pathogenesis of ulcerative colitis (UC); therefore, it has become an attractive target for the treatment of UC. Qing Hua Chang Yin (QHCY) is a traditional Chinese formula, which has been used for many years to clinically treat conditions associated with inflammatory bowel diseases, such as UC. However, the precise mechanisms behind its anti-inflammatory effects remain largely unknown. In this study, using the dextran sulfate sodium (DSS)-induced colitis mouse model, we evaluated the therapeutic effects of QHCY against UC and elucidated the possible underlying molecular mechanisms. We found that the administration of QHCY profoundly ameliorated DSS-induced clinical manifestations, colon shortening and histological damage in the mice with colitis. In addition, treatment with QHCY significantly decreased the DSS-induced secretion of serum amylase. Moreover, QHCY significantly inhibited the DSS-induced expression of TLR4 and myeloid differentiation primary response gene 88 (MyD88), the phosphorylation of IκB and the nuclear translocation of NF-κB. Taken together, our findings suggest that the suppression of the TLR4/NF-κB signaling pathway may be one of the mechanisms involved in the therapeutic effects of QHCY against UC.

Silver nanowire (AgNWs) transparent conductive film (TCF) is considered to be the most favorable material to replace indium tin oxide (ITO) as the next-generation transparent conductive film. However, the disadvantages of AgNWs, such as easy oxidation and high wire-wire junction resistance, dramatically limit its commercial application. In this paper, moisture treatment was adopted, and water was dripped on the surface of AgNWs film or breathed on the surface so that the surface was covered with a layer of water vapor. The morphology of silver nanowire mesh nodes is complex, and the curvature is large. According to the capillary condensation theory, water molecules preferentially condense near the geometric surface with significant curvature. The capillary force is generated, making the wire-wire junction of AgNWs mesh bond tightly, resulting in good ohmic contact. The experimental results show that AgNWs-TCF treated by moisture has better conductivity, with an average sheet resistance of 20 Ω/sq and more uniform electrical properties. The bending test and adhesion test showed that AgNWs-TCF treated by moisture still exhibited good mechanical bending resistance and environmental stability.

This paper proposes the investigation of an automatic monitoring system of transverse diffusion of transmission line engineering based on automatic control, intending to enhance the safety of power grid operation and the effectiveness of detecting parameters like the size of the opposite side of the crimped wire. Using the same microcomputer as the primary control device, a transmission line automatic compression control system is constructed in this paper. It has three infrared sensors that can measure three groups of distances, an electric sensor that measures the hydraulic pump’s output, and an electric drive that controls the hydraulic pump’s opening and closing. The upper computer can count the number of wire movements and measure the distance traveled by each step of the wire. The lower machine moves the metal directly depending on the instructions from the upper computer, measures the hydraulic pump’s pressure, and measures the length of three distinct groups of hexagonal metal. Time pressure and three wire groups that are not connected are also visible in the lower computer’s serial port. This system reduces collision costs, saves a lot of labor, increases engineering and production efficiency, and can be useful in wire crimping technology.
