The invention discloses a yeast beta-glucan preparation method based on high pressure-microjet homogenization treatment, and belongs to the technical field of zymosan extraction. The method comprises the following steps: carrying out high pressure-microjet homogenization pretreatment on active dry yeast, then carrying out autolysis treatment, then extracting beta-glucan by an acid-alkali method, and finally carrying out freeze drying to obtain a high-purity product. The core of the method is that the yeast cell walls are subjected to physical wall breaking by adopting a high pressure-microjet homogenization technology, and the extraction rate and the purity of the beta-glucan are remarkably improved by combining with an optimized acid-alkali treatment process. Compared with a traditional enzymolysis method, the method has the advantages that damage of exogenous enzyme to the beta-glucan structure is avoided, the purity of the obtained product reaches 84% or above, the content of protein impurities is lower than 0.2%, a new way is provided for efficient utilization of yeast cell wall resources, and the method is suitable for the fields of food, medicine and health care products.

Compositions and methods for treating cancer, particularly leukemia, using a cytotoxic composition comprising monocytes activated by β-glucan. The monocytes are preferably incubated with the β-glucan and then processed to extract particles, such as microvesicles and exosomes from the treated monocytes to produce the cytotoxic composition. Preferably the cytotoxic composition comprises at least 50% exosomes having a size of 150 nm or less that are activated with β-glucan. Zymosan is the preferred β-glucan. The cytotoxic composition has an apoptosis effect. When a subject having cancer is treated according to preferred embodiments, the cytotoxic composition preferably induces a cytokine response in the subject's immune system. The combination of the cytotoxic composition and cytokine response are synergistic.

The invention relates to the technical field of quality detection of traditional Chinese medicine, and particularly discloses a detection method of a traditional Chinese medicine composition for repairing kidney injury and the traditional Chinese medicine composition.The traditional Chinese medicine composition is prepared by matching poria cocos, astragalus membranaceus, American ginseng and cordyceps sobolifera water extracts according to a specific proportion and being supplemented with zymosan and water-soluble vitamin E. According to the detection method, a high-sensitivity CMOS image sensor is adopted to collect a two-dimensional optical image when components in an HPLC system flow out, and the visibility of a low-concentration signal is improved by combining local contrast enhancement, frequency domain filtering and RO I segmentation; an overlapped peak region is identified through a customized lightweight convolutional neural network model, and the identification precision is improved by fusing multi-scale features, an attention mechanism and a knowledge distillation strategy; constructing an image texture and ultraviolet spectrum multi-modal fusion analysis matrix, and combining principal component analysis and component specificity weight factors to realize accurate quantification; and finally outputting the annotated image and the structured quality report.

The invention belongs to the technical field of construction of disease animal models, and discloses a construction method of a psoriatic arthritis animal model, which adopts zymosan mannan and a complete Freund's adjuvant to jointly induce psoriatic arthritis for modeling. According to the invention, the zymosan mannan and the complete Freund's adjuvant are used for combined induction, so that the typical pathological manifestation of psoriatic arthritis can be stably simulated, and particularly, the model is superior to the existing animal model in the aspect of simultaneously inducing joint inflammation and psoriasis-like skin lesion, and is closer to the pathological characteristics of clinical patients.

The present invention relates to compositions and methods for treating cancer, particularly leukemia, using a cytotoxic composition comprising monocytes activated by β-glucan. The monocytes are preferably incubated with β-glucan and then treated to extract particles, such as microvesicles and exosomes, from the treated monocytes to produce the cytotoxic composition. Preferably, the cytotoxic composition contains at least 50% β-glucan-activated exosomes having a size of 150 nm or less. Zymosan is a preferred β-glucan. The cytotoxic composition has an apoptotic effect. When a subject with cancer is treated according to the preferred embodiment, the cytotoxic composition preferably induces a cytokine response in the subject's immune system.
