Disclosed are an APR protection method and device, and a computer storage medium. A preamplifier PA of each of two optical amplifier units at two ends of a transmission line is connected to a booster amplifier BA of the other amplifier unit by an optical fiber. The method comprises: when a reception state of PA of at least one of two amplifier units is a loss of signal state and a switch chip of said amplifier unit detects a link interruption signal, activating an APR protection state of said amplifier unit which is to turn off BA output of said amplifier unit; when the switch chip of at least one of two amplifier units detects a link conduction signal, deactivating the APR protection state of the present amplifier unit to restore a state of BA of said amplifier unit to a state before the APR protection state is activated.

The present disclosure provides an arctigenin liquid nano-preparation and a preparation method thereof, and relates to the technical field of pharmaceutical preparation. In the present disclosure, arctigenin is prepared into a liquid nano-preparation, having advantages of distribution of a droplet diameter on nanoscale, significantly increased specific surface area, rapid absorption, and high bioavailability. Meanwhile, nano-preparation entered the body can be captured by wandering leucocytes, and a medicament is delivered to inflammatory lesions through chemiotaxis, thereby conferring a targeted drug delivery feature on the arctigenin and making a therapy more targeted.

Arctigenin liquid nano-preparation and preparation method thereof

Disclosed are a long-distance optical fiber detecting method, apparatus, device and system, and a storage medium. The method comprises: in response to a detection request of a target node on a to-be-detected optical fiber, determining a first and second sampling sequence that are formed by respectively propagating, on said optical fiber, a first and second optical signal respectively sent from each end of the optical fiber through an OTDR; determining a total length of the optical fiber; generating a detection result according to the first and second sampling sequence and the total length, and sending the detection result to the target node. By determining the first and second sampling sequence and combining the total length of the optical fiber, a detection result of the to-be-detected optical fiber is generated.
