This invention discloses a yam vesicle nanomaterial, its preparation method, and its application for reducing the toxicity of radiotherapy for breast cancer. It belongs to the field of biomedical technology. The method includes adding PBS to the yam at a weight-to-volume ratio of 1:3 for juicing, sieving the yam juice, centrifuging the resulting yam filtrate at low speed to obtain supernatant A, centrifuging supernatant A at medium speed to obtain supernatant B, centrifuging supernatant B at ultra-high speed, resuspending the precipitate in PBS, and obtaining the yam vesicle nanomaterial. In this invention, the yam vesicle nanomaterial uses yam as raw material. The obtained yam vesicle nanomaterial has natural bone marrow targeting properties, requires no additional modification, and can spontaneously accumulate in the bone marrow after intravenous injection, specifically protecting the hematopoietic system. It can also simultaneously prevent the decrease in white blood cells, red blood cells, and platelets caused by radiotherapy, comprehensively alleviating the bone marrow suppression side effects of radiotherapy without affecting the efficacy of tumor radiotherapy.

The application provides a yam directional growth traction device, and belongs to the technical field of agricultural machinery. The device comprises a support frame, guide wheels, a traction rope, a power mechanism and a self-locking clamp. Three guide wheels are arranged on the top of the support frame. The traction rope passes through each guide wheel in sequence to form a Z-shaped path. The power mechanism is arranged on one side of the support frame and is used for adjusting the speed of yam vine traction. The self-locking clamp is arranged on the side of the support frame away from the power mechanism and is used for clamping the yam vine. Through the cooperative work of the power mechanism, the traction rope, the guide wheels and the self-locking clamp, the automatic directional traction of the yam vine is realized. The planting personnel only need to clamp the vine in the initial growth stage, and the subsequent traction process is automatically completed by the device, so that the manual intervention is greatly reduced, the labor intensity is reduced, the planting efficiency is improved, and the demand for large-scale planting can be met.

This invention discloses a sports nutrition food for post-exercise recovery and blood glucose management. Each 40g portion contains Astragalus membranaceus extract, Dioscorea opposita extract, white kidney bean extract, mulberry leaf extract, L-arabinose, cinnamon extract, whey protein peptides, and a mineral-vitamin-probiotic premix. This invention utilizes a six-fold blood glucose control pathway through a four-mineral glucose control matrix, triple carbohydrate blocking, probiotics, and dual tonification of Qi and Yin with traditional Chinese medicine. Animal experiments showed that the fasting blood glucose level in the full-formula group decreased to 6.3 mmol / L, significantly better than the control group (*p*<0.05). All ingredients comply with national standards for sports nutrition foods and are safe and compliant.

This invention discloses a yam stake-planting machine, comprising a tractor and a stake-planting device. The stake-planting device includes a suspension and several pairs of stake-planting units. The stake-planting device is connected to the rear of the tractor via its suspension. The suspension is horizontally arranged, and several pairs of stake-planting units are spaced apart on the upper side of the suspension. Each pair of stake-planting units includes two stake-planting units arranged front-to-back and cross-facing on the upper side of the suspension. Each stake-planting unit includes a slide cylinder, an inclined mounting plate, a guide rod mounting seat, a guide rod, a stake-planting cylinder, a fixing block, and grippers. The slide cylinder is mounted on the upper side of the suspension, and its slide can slide left and right. The inclined mounting plate is inclinedly arranged at one end of the slide. The guide rod mounting seat is mounted on the side of the inclined mounting plate opposite to the slide. The cylinder body of the stake-planting cylinder is fixed on the guide rod mounting seat. The piston rod of the stake-planting cylinder is parallel to the guide rod and is fixedly connected to the guide rod via the fixing block. Grippers that can automatically clamp and release the stake or rod are installed on the guide rod. This invention solves the problem of time-consuming and labor-intensive manual stake-planting in current yam cultivation.
