The utility model discloses a packaging bag sealing performance detection device and an auxiliary assembly, comprising a detection box, a hinge is fixedly arranged on the front side of the detection box, a box cover is hinged on the surface of the detection box through the hinge, an auxiliary support assembly is arranged at the bottom of the box cover, and a mounting rack is lapped on the top of the box cover. The mounting frame is connected with the box cover through bolts, and a mounting plate is fixedly arranged in the mounting frame. Through the arrangement of the box cover, the mounting frame, the mounting plate, the lower fixed magnet, the upper fixed magnet, the movable plate and the vacuumizing assembly, the sealing performance of a plurality of packaging bags can be conveniently detected at the same time, the situation that the packaging bag detection speed is reduced due to the fact that the sealing performance of only one packaging bag can be detected at a time is avoided, and therefore the packaging bag detection speed is increased; and the side edge of the packaging bag is clamped through a lower fixed magnet and an upper fixed magnet, so that errors of a detection result caused by blocking of the surface of the packaging bag are avoided.

This invention relates to the field of biotechnology, and in particular to a primer-probe combination for detecting methylation sites in cancer and its applications. This invention is the first to discover that abnormal methylation at specific sites of the TRIB3 gene is significantly associated with the occurrence and development of colorectal cancer, and abnormal methylation at specific sites of the MAPT gene is significantly associated with the occurrence and development of gastric cancer. This correlation has not been publicly reported in the prior art, possessing novelty and significant clinical application value. The primer-probe combination provided by this invention is used to detect the methylation status of the TRIB3 gene or the MAPT gene in a sample. Specifically, when the primer-probe combination is used to detect the methylation level at specific sites of the TRIB3 gene, it can be used for the auxiliary diagnosis, early screening, or risk assessment of colorectal cancer; when the primer-probe combination is used to detect the methylation level at specific sites of the MAPT gene, it can be used for the auxiliary diagnosis, early screening, or risk assessment of gastric cancer.

The invention provides a synchronization method and system for power line carrier communication and electronic equipment, and the method comprises the steps: obtaining signal data of a sender in power line carrier communication, and processing the signal data to obtain a plurality of data frames; inserting a leader sequence at an initial position in a data frame to generate a marked data frame; acquiring a local sequence of a sender, and performing convolution calculation on the marked data frame and the local sequence to obtain a convolution value; judging whether the convolution value exceeds a preset threshold value or not, and if yes, determining the position exceeding the threshold value as a peak value position; intercepting a marked data segment according to the peak value position, and performing autocorrelation calculation on the marked data segment to determine the initial position of the data frame; and enabling the receiver to receive the data frames from the starting position of each data frame. The problem of insufficient high-precision synchronization rate in power line carrier communication is solved.
