The invention provides a spine tractor which comprises a main body support, a sliding part, a lifting mechanism, a molar tooth supporting plate and a first bandage, and the sliding part is slidably connected with the main body support in the vertical direction; the lifting mechanism is used for driving the sliding piece to slide; the molar supporting plate is fixedly connected with the sliding piece, and the molar supporting plate is provided with a supporting part which is used for being placed in an oral cavity to support molar teeth; the first binding band is fixedly connected with the sliding piece and used for binding the head of a user to the sliding piece. The fixing tube, the sliding part and the molar supporting plate are arranged, the traction force application point is changed into a molar area from the neck, compression of neck blood vessels and muscles is avoided, it is ensured that a patient with angiosclerosis can also safely use the device, and due to the fact that the requirement for stability of stress at the molar is high, stable upward traction force can be provided through a telescopic structure, and the traction effect is good. The damage to the head caused by shaking or inclination of the molar supporting plate is avoided.

The present invention provides a method and system for detecting vascular sclerosis parameters using a light-sensitive sensor. The method comprises: acquiring and processing raw pulse wave signals through a preset wearable device sensor to determine pulse feature points; transmitting the pulse feature points to a preset big data analysis platform for analysis and calculation to determine vital sign data; transmitting the vital sign data to a preset artificial intelligence algorithm for analysis and processing to determine analysis results; using the analysis results to determine whether the subject under test has precursors to vascular sclerosis; regularly collecting and transmitting the analysis results to a preset simulation device to establish a pathological model of precursors to vascular sclerosis; and determining in real time whether the subject's vital sign data is abnormal based on the pathological model of precursors to vascular sclerosis. The system comprises a feature extraction module, a data analysis module, a pathological model establishment module, and a real-time monitoring module. The present invention can quickly query the wearer's basic information and issue early warnings to users with a high degree of match.

The present invention relates to an applied study on the component analysis and function of a flavonoid extract of an umbelliferae plant seed. The preparation method of the extract is as follows: the umbelliferae plant seeds are crushed into powder, and then the umbelliferae plant seeds are extracted and concentrated using an ethanol solution, and extracted with solvents of different polarities to obtain a corresponding umbelliferae plant seed extract, and then the umbelliferae plant seed extract is subjected to flavonoid component analysis and content testing. It will be verified that the flavonoid extract provided by the present invention can prevent, improve or treat peroxidation pathways and inflammation-related diseases, and can also be used for diseases related to abnormal expression of α-glucosidase and α-amylase, such as cancer of various tissues and organs, hyperuricemia, diabetes, hyperglycemia, hyperlipidemia, cardiovascular disease, vascular sclerosis or premature aging, etc., and can be used for the development of drugs, health foods or skin care products.
