Abstract: Disclosed is a display substrate, including a base substrate (100), a circuit structure layer disposed on the base substrate (100), and a light emitting structure layer. The circuit structure layer includes a plurality of pixel circuits located in a first display region (A1), at least one first trace 231 extending along a first direction (D1), at least one second trace 232 extending along a second direction (D2), and at least one third trace located in a peripheral region (BB). The at least one first trace (231) is electrically connected with the at least one second trace (232) and the at least one third trace is electrically connected with at least one of following; the at least one first trace (231) and the at least one second trace (232).

Abstract: The present disclosure provides a primer combination, a kit, and a method for detecting Clostridium piliforme based on loop-mediated isothermal amplification-lateral flow dipstick (LAMP-LFD), belonging to the technical field of medical molecular biology detection. In the present disclosure, the primer combination includes a forward outer primer F3, a backward outer primer B3, a forward inner primer FIP, a backward inner primer BIP, a loop primer LF, and a probe PB1. The present disclosure further provides a kit and a method for detecting Clostridium piliforme based on the primer combination. The kit and the method can detect the Clostridium piliforme with a simple detection process, a low time consumption, easy determination of results, and high detection accuracy and sensitivity.
