    Abstract: The present disclosure discloses a medium for primary isolation of Porphyromonas gingivalis, and a method for preparing the medium and use thereof. The medium for primary isolation of Porphyromonas gingivalis includes the following components in parts by weight: 10-20 parts of a mixed peptone, 5-10 parts of a yeast extract powder, 1-5 parts of sodium chloride, 10-15 parts of agar, 0.5-1.0 parts of glucose, 0.2-0.8 parts of sodium bicarbonate, 0.1-0.5 parts of an L-cysteine salt, 0.1-0.5 parts of soluble sodium pyrophosphate, 0.0001-0.0005 parts of hemin, 0.00001-0.00005 parts of vitamin K, 500-1000 parts of water and 5-10 parts of a sterile defiberized sheep blood. By adopting the medium for primary isolation of Porphyromonas gingivalis provided by examples of the present disclosure, a culture period of primary isolation of Porphyromonas gingivalis can be greatly shortened, and the primary isolation of Porphyromonas gingivalis can be quickly conducted.

    Abstract: A knowledge graph-based method for recommending traditional Chinese medicine (TCM) prescriptions is provided. The method integrates a knowledge graph embedding model, a multi-head attention mechanism, graph convolutions, and other techniques to combine graph features with a recommendation system, for comprehensively considering patient conditions to recommend TCM prescription. Taking TCM case description texts as the research object and integrating with TCM knowledge graph information, the method draws from the clinical experience of renowned TCM experts and fully considers various individual factors such as medicinal properties, efficacy, medical conditions, and patient constitutions. Based on the holistic principles of TCM and the ideology of syndrome differentiation and treatment, the method selects different herbal combinations based on varying symptoms and medical conditions of patients. The proposed TCM prescription recommendation method, incorporating the knowledge graph, considers the complex relationships between individual signs as well as symptoms and medications.

    Abstract: The present disclosure relates to a preparation process of a Ti3AlC2 ceramic phase-toughened molybdenum alloy. The preparation process includes: mixing MoO2 and Ti3AlC2 powders, sieving to obtain a mixed powder, and then conducting high-temperature hydrogen reduction; mixing a resulting reduced powder with a coarse-grained Mo powder to obtain a precursor powder; putting the precursor powder into a cladding material to allow hot-pressed sintering; subjecting an obtained sintered molybdenum alloy to high-temperature treatment and thermoplastic processing in sequence; and annealing an obtained processed molybdenum alloy to obtain a high-strength and high-toughness molybdenum alloy. In the present disclosure, a Ti3AlC2-containing ultrafine powder prepared by reduction is mixed with the commercial coarse-grained molybdenum powder in a certain proportion to obtain the precursor powder. After the precursor powder is subjected to the hot-pressed sintering, the molybdenum alloy can achieve a higher density and finer grains.
