A vibration excitation device comprises an input shaft, eccentric blocks and eccentric torque output shafts. The input shaft can drive the eccentric torque output shafts to rotate, and the eccentric blocks sleeve the outer sides of the eccentric torque output shafts. The eccentric blocks on the eccentric torque output shafts synchronously rotate along with rotation of the eccentric torque output shafts and generate a centrifugal force. The centrifugal forces of the eccentric blocks on one pair of exactly opposite eccentric torque output shafts are equal in magnitude and opposite in direction, but each pair of centrifugal forces forms a force couple. The magnitude and direction of the torque of each force couple periodically change based on the sine function rule over time, and under the action of the torques of the two pairs of force couples, the vibration excitation device generates an arc vibration in a horizontal direction.

A serum microRNA (miRNA) marker suitable for early screening and diagnosis of ossification of posterior longitudinal ligament (OPLL) and its application in the diagnostic reagent or kit for the OPLL. Biomarker miRNA-563, miRNA-196b, miRNA-10a and miRNA-129 have high diagnostic value for OPLL, and the development and application of the related serum miRNA biomarker detection reagent kit. It can be applied in the screening of ossification of posterior longitudinal ligament disease, supporting the diagnosis of OPLL more quickly and accurately, evaluate the patient's ossification condition, and may lay down the foundation for improving clinical therapeutic effect.
