With the gradual expansion of aquaculture industry in China, the frequent occurrence of diseases in aquatic animal aquaculture and the pollution of aquatic water are becoming more and more serious. The long-term use of antibiotics and traditional vaccines in aquaculture has caused water pollution, drug-resistant strains, antibiotic residues, and other problems, which restricts the healthy development of aquaculture industry. Plant polysaccharides play an important role in replacing antibiotics. Plant polysaccharides exist in the leaves, flowers, roots, stems, and fruits of plants. They are macromolecular polymers that connect various monosaccharides by glycosidic bonds. Plant polysaccharides have the advantages of safety, high efficiency, low residue and no drug resistance. Plant polysaccharides have many biological functions, such as regulating immunity, anti-oxidation, lowering blood sugar, anti-tumor, and improving intestinal health. The application of plant polysaccharides in animal production can improve body health, enhance immunity and antioxidant capacity, and improve production performance. Therefore, this paper mainly reviewed the physicochemical properties, biological functions of plant polysaccharides and their application in aquaculture, so as to provide a reference for their further promotion and application in aquaculture.

In the Legacy of Huangdi Neijing Suwen, the spleen is likened to the "Official in Charge of Admonition and Arbitration", and its mechanism of action is closely related to the physiological characteristics of the spleen. The spleen's function is based on its " concealment of the mind and mastery of thought", and this provides ideological guidance for the spleen's "remonstration". Furthermore, the spleen's "central position to instill the four sides" creates convenient conditions for the rapid arrival of "remonstration", and its "main transport and transformation" provides an important source of energy for the "Zhi Zhou"; it further ensures the orderly development of the "remonstration" function. The "spleen is the guard" is the concrete embodiment of "remonstration" by the spleen that plays the role of guarding the body and resisting external evil. Western medicine believes that this theory has something in common with the immune function of the body. This paper summarizes the interpretation of the spleen as the "Official in Charge of Admonition and Arbitration" by medical scholars through the ages, relying on the ideas of "comparing images with similarities" and "preventing diseases" based on the philosophy of traditional Chinese medicine that considers the physiological characteristics of the spleen related to Chinese medicine and the interpretation of its theoretical connotation by modern medicine. This paper provides a reference for the clinical management of spleen and stomach diseases, neurological diseases, and immune disorders in Chinese medicine. [ABSTRACT FROM AUTHOR]

Based on the existing sequential function method for one-dimensional and two-dimensional surface heat flux identification, this paper presents a combination of neural network and sequential function method considering the real-time difficulty of three-dimensional identification. In this paper, a neural network is designed to correct the three-dimensional effects based on the results of one-dimensional identification, which can get accurate real-time results of peak heat flux. Furthermore, PSO algorithm is introduced to optimize the initial weights and thresholds of the neural network in order to obtain a better model. It can be seen from the test results that the method presented for the peak heat flux is accurate with errors less than 4%.The method avoids time complexity of three-dimensional identification and has good noise immunity and stability at the same time.

The trophoblasts of the hydatidiform mole and those of normal pregnancy were both originated from the ectoderm and were regulated by paternally imprinted genes. Trophoblasts of normal pregnancy during early pregnancy could induce immune tolerance at the maternal-fetal interface by expressing non-classical human leukocyte antigen and inducing immune cell suppression to ensure fetuses′ normal growth and development. However, the current understanding of the immunological changes of the hydatidiform mole was still limited. Recently, studies have revealed that the interaction between trophoblasts of the hydatidiform mole and immune cells of the maternal-fetal interface was a crucial factor that influenced the prognosis after uterine evacuation. The immune response of peripheral blood mononuclear cell (PBMC) in patients with mole was associated with the advance of mole, which reflected the adaptive changes of the patient′s immune system to the continuous pregnancy of mole. In order to explore the above -mentioned immunological characteristics of hydatidiform mole, this paper reviewed the recent research progress on the composition of immune cells at the maternal-fetal interface of hydatidiform mole and the immune status of PBMC.
