[Objective]Taking tobacco as experiment material, extraction process of tobacco polypeptide and its antioxidant activity was studied in this research. [Method]Tobacco polypeptide was extracted by enzyme-assisted water extraction and alcohol precipitation. Single factor test was used to investigate the effects of enzyme addition, enzymolysis pH, enzymolysis time, extraction temperature and substrate concentration on the extraction rate of tobacco polypeptide. The optimal extraction process of tobacco polypeptide was determined by response surface method. The scavenging activity of tobacco polypeptide on DPPH and hydroxyl radicals was detected. [Result]The optimal extraction process for tobacco polypeptide was as follows (based on 1 g tobacco sample):enzyme addition 4 200 U, enzymolysis pH 8. 2, enzymolysis time 2. 5 h, extraction temperature 49 ℃ and the substrate concentration 4. 2%. Under the optimized extraction process, the extraction rate of tobacco polypeptide was 88. 23 mg / g. The scavenging rates of DPPH and hydroxyl radicals of the tobacco polypeptide were 83. 09% and 73. 84%, respectively. Tobacco polypeptide was of a certain antioxidant capacity. [Conclusion] This study provides a certain theoretical basis and technical guidance for the medicinal value of tobacco leaves and the drug development of tobacco peptides. [ABSTRACT FROM AUTHOR]

Objective To explore the effect of family-centered health education intervention on children with autoimmune diseases (AD). Methods A total of 120 children with AD admitted to this department from April 2020 to February 2022 were selected and divided into two groups according to the random number table method. The control group included 60 children who received routine nursing, while the observation group included 60 children who received family-centered health education on top of routine nursing. Both groups were followed up for 6 months. The treatment adherence, family health knowledge, frequency of disease onset, and family satisfaction were compared between the two groups. Results The treatment adherence score of the observation group [(5.69±1.10) points] was higher than that of the control group [(4.12±0. 86) points]. The scores of the family′s health knowledge, including causes of disease occurrence, treatment measures, and precautions for prognosis [ (80.89±7.60), (81.88±7.74), and (79.85±8.4) points, respectively], were all higher than those of the control group [(76.74±6.78), (77.71±7.22), and (76. 15±7.64) points, respectively]. The frequency of disease onset at 6 months after discharge [(3.11±0.43) times] was lower than that of the control group [(3.38±0.65) times], and the differences were statistically significant (P＜0.05). The family satisfaction rate in the observation group (95.00%) was higher than that in the control group (83.33%), and the difference was statistically significant (P＜0.05). Conclusion Family-centered health education intervention can improve the health knowledge of families and the treatment adherence of children with AD, reduce the frequency of disease onset, benefit prognosis, and achieve higher family satisfaction.

Submerged rigid vegetation causes uneven vertical distribution and streamwise differences of hydraulic parameters such as time- averaged flow velocity, turbulence intensity, and Reynolds stress by altering the flow structure. ADV is adopted to measure the flow velocity under three submergence ratios of 3. 0, 4. 0, and 5. 0, combined with statistical methods, the differences in velocity and turbulence characteristics within the vegetation section and its upstream and downstream transition sections are systematically analyzed. The results show that vegetation significantly enhances water flow turbulence, and the values of turbulence characteristics are positively correlated with submergence ratios. Within the vegetation segment, the differences in velocity are more significant in the two vertical zones: one is the vegetation layer under low submergence and the other is the free flow layer under high submergence. Furthermore, the values of turbulence characteristics are enhanced along the path, and the vertical distribution has similarity, with the location of maximum point is near the top of the canopy. When the submergence ratio meets the formation and development conditions of KH vortices, the turning point appears gradually in the vertical distribution curves of turbulent characteristics within the vegetation segment, near which the gradient value sharply decreases and approaches 0. In addition, the number of cross sections with turning points increases with submergence ratios increasing. It is verified that this point can serve as the upper boundary point of KH vortices in the fully developed turbulent flow region. [ABSTRACT FROM AUTHOR]
