Described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate specific nerves (e.g., sensory nerves vs. motor nerves) for nerve transplants and other surgeries. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate between different types of lymphnodes and / or lymphatic pathways, e.g., to safely and effectively perform vascularized lymph node transplantation in the treatment of lymphedema. Also described herein is a multiplex platform that uses ultrasmall nanoparticles (e.g., C dots and C' dots) to graphically differentiate parathyroid tissue.

The present invention relates to a parathyroid sensing system comprising: a modulator for generating a modulation signal having a predetermined frequency; a lock-in amplifier and a light source whichreceive information on the modulation signal; an excitation filter for transmitting, among light emitting from the light source, only excitation light that excites the parathyroid glands; a probe andan emission filter connected to the probe and selectively transmitting only autofluorescence emitting from the parathyroid glands; a near-infrared sensor for sensing the autofluorescence that has passed through the emission filter, and converting same into an electric signal; and a speaker for generating an alarm through the electric signal. By means of the present invention, the locations of theparathyroid glands may be precisely identified even when lights are turned on in an operating room, and convenience may be provided by alerting a surgeon by means of an alarm when the parathyroid glands are detected. In addition, the locations of the parathyroid glands may be precisely detected, even when the probe is not directly in contact with the parathyroid glands, by using the autofluorescence characteristics of the parathyroid glands.

The present invention relates to the technical field of parathyroid identification, in particular to a method for intraoperative real-time identification of parathyroid glands based on near-infrared autofluorescence, comprising the following steps: imaging suspicious parathyroid glands; obtaining fluorescence spectra of suspicious parathyroid glands and surrounding tissues data; judging whether it is parathyroid in the spectrogram; performing big data analysis; The research on the identification platform combines clinical medicine with optoelectronic technology and artificial intelligence, and will eliminate various subjective and objective interference factors to the greatest extent, and realize real-time, objective, non-invasive, non-contrast agent-free, intelligent and convenient positioning and identification of parathyroid To solve the biggest problem in thyroid surgery, establishing an objective and rapid method for locating and identifying parathyroid glands is of great significance to the development of thyroid surgery.

The invention discloses a glycoside enrichment of Ligustrum lucidum, the preparation method of which comprises the following steps: adding 10-14 times of ethanol with a volume concentration of 50-80% to Ligustrum lucidum, refluxing and extracting for 1-3h, filtering, and Add 8 times the amount of ethanol with a volume concentration of 50-80% to the residue, reflux for extraction for 1-3 hours, filter, combine the two filtrates, recover the solvent, add an appropriate amount of ethyl acetate for extraction, discard the ethyl acetate layer, and add water to the water layer to saturate Extract with n-butanol, combine the water-saturated n-butanol layers, concentrate, and vacuum-dry to obtain the glycoside enrichment of Ligustrum lucidum. The invention also discloses the application of the Ligustrum lucidum glucoside enrichment in the preparation of medicine for treating hypoparathyroidism.
