In order to optimize the allocation of water resources in the Yellow River Basin and the irrigation regime for winter wheat crops in southeast Shanxi Province areas, based on the meteorological data from 1960 to 2019 in Yangcheng County, the annual changes of water requirement and rainfall at different growth stages of winter wheat were analyzed and calculated. In the typical irrigation year (25%, 50%, 75% and 95%), the coupling analysis of the water requirement and rainfall was carried out, and the irrigation water consumption of the winter wheat was calculated. The results show that in the past 60 years, the climate tendency rate of winter wheat water requirement increases with the change of 0.593 mm/(10a), and the annual average water requirement is 586.09 mm in southeast Shanxi Province areas. The climatic tendency rate of rainfall increases by 9.827 mm/(10 a), and the annual average value of rainfall is 213.66 mm. The climatic tendency rate of water requirement of winter wheat is the highest at jointing-heading stage. Under four typical irrigation years (25%, 50%, 75% and 95%), the coupling degree of rainfall and water demand in the whole growth period of winter wheat is 0.43, 0.33, 0.28 and 0.18 respectively. Natural rainfall cannot meet the water requirement of winter wheat growth. The amount of supplementary irrigation water is 261.74 mm, 427.45 mm, 554.34 mm and 674.66 mm respectively. Except typical irrigation years of 25%, the amount of supplementary irrigation water is the largest at heading to filling period. The supplementary irrigation water should be 116.87 mm, 142.55 mm and 171.54 mm respectively. [ABSTRACT FROM AUTHOR]

In order to explore the effects of amylose, amylopectin and β-glucan on the synthesis of resistant starch, 30 glutinous barley with different genotypes were used as the experimental materials to determine the starch components, β-glucan content and resistant starch content at 7, 14, and 21 days after flowering (early grain-filling stage), and the maturation period. The results showed that there were significant differences among the starch components, β-glucan content and resistant starch content in the mature grains of 30 barley materials with different genotypes. The content of resistant starch ranged from 0.28% to 1.22%, with an average value of 0.56%. The content of resistant starch in the strain Xi C1 was the highest (1.22%), followed by Gankennuo No.3 (0.91%). The two strains with the lowest content of resistant starch were 2014(7)-5-1-2 (0.28%) and 2014(1)-1-2-1 (0.29%). With the advance of grain filling process, the content of resistant starch in Gankennuo No.3 showed an increasing trend, and reached the maximum at the maturation period. The strain 2014(1)-1-2-1 showed a trend of first increasing and then decreasing, while the variation trends for the strain Xi C1 and strain 2014(7)-5-1-2 were exactly opposite to that of the strain 2014(1)-1-2-1. Among the 30 barley materials, the contents of β-glucan in 13 materials were higher than 6%, indicating that they were typical high β-glucan materials. The content of β-glucan in Zhongnuo No.8 was as high as 8.59%. The amylose content ranged from 1.81% to 18.54%, and the amylopectin content ranged from 81.46% to 98.19%. Among the 30 barley materials, the contents of amylopectin in 22 materials were more than 90%, indicating that they were high-amylopectin starch materials. The contents of resistant starch in 30 barley grains with different genotypes were different, and the accumulation characteristics of resistant starch were also different. Therefore, the correlation analysis showed that the content of resistant starch was significantly positively correlated with the content of amylose, but was significantly negatively correlated with the content of β-glucan.

OBJECTIVE: To explore the prescription rules of non-alcoholic fatty liver disease (NAFLD) from sputum dampness, and analyze the potential mechanism of core prescription drugs. METHODS: Clinical research literature on the treatment of NAFLD from phlegm dampness was collected, and systematic clustering and association rules analysis were carried out on taste and attribution of prescription drugs. After determining the core prescription for treating NAFLD from the perspective of phlegm-dampness theory, we searched the database to obtain the drug’ s effective ingredient targets and disease targets. The intersection of these targets was used to construct a protein-protein interaction network in the STRING database. Subsequently, all intersecting targets were scored in Cytoscape to identify core targets. Gene Ontology functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were conducted on key targets. The analysis results were imported into Cytoscape to construct a network diagram of active ingredients-targets-disease pathways for traditional Chinese medicine. RESULTS: After screening, a total of 119 prescriptions were obtained, including 153 kinds of drugs, which were sweet and warm, and were more common in the liver and spleen. Analysis of association rules showed that Crataegi Folium, Wolfiporia Cocos, Alisma Orientale, Atractylodes Macrocephala Koidz, Radix Salviae, Arum Ternatum Thunb and Citrus Reticulata were the core drugs for the treatment of NAFLD. Core prescription combination of “Crataegi Folium, Cassiae Semen, Alisma Orientale, Radix Salviae, Radix Bupleuri and Curcumae Radix” was obtained by cluster analysis. Network pharmacological analysis showed that there were 248 intersection targets between the core prescription and NAFLD, and the signal transduction and transcriptional activator 3 and myelocytomatosis oncogene cellular homolog were the core targets for the treatment of NAFLD from sputum wetness. Forkhead box O, tumor necrosis factor and phosphatidylinositol 3 kinase-protein kinase B signaling pathways were the main signaling pathways of phlegmdampness treatment of NAFLD. Methyl heptenone, quercetin and kaempferol were the main effective components of the core prescription. CONCLUSIONS: The treatment of NAFLD from phlegm dampness is mainly sweet and warm medicine, which is inseparable from the regulation of liver and spleen, and Crataegi Folium, Wolfiporia Cocos, Alisma Orientale, Atractylodes Macrocephala Koidz, Radix Salviae, Arum Ternatum Thunb and Citrus Reticulata are commonly used drugs for the treatment of NAFLD from phlegm dampness, and the core prescription of NAFLD from phlegm dampness mainly plays a therapeutic role in NAFLD by participating into the regulation of lipid metabolism, inflammatory response, oxidative stress and other biological processes.

The extremely complex sea state data of offshore wind farms makes the input parameters used for wave height prediction extremely unstable, and screening out key information and improving the quality of input parameters can greatly improve the accuracy of wave height prediction. Based on the offshore data of the wind farm in Laoting Bodhi Island for nearly one year, a wave prediction model based on random forest (RF), whale optimization algorithm (WOA), variational mode decomposition (VMD) and bidirectional gated recurrent unit (BiGRU) was constructed. The model used random forest to screen input variables such as environmental characteristics to effectively reduce data redundancy, and then adaptively determined the optimal parameters and adaptively decomposed the original sequence based on the WOA-VMD model to improve data quality and eliminate the interference of data noise. In addition, a BiGRU algorithm based on attention mechanism optimization was proposed for wave prediction, and the attention mechanism of random forest would assign different weights to the hidden layer state of BiGRU to strengthen the influence of key information. The experimental results show that compared with other models, the model has higher input quality, higher prediction accuracy and more accurate fitting, which is of great significance for the prediction of wind farm waves.
