In this paper five nutritive indexes of Ulva pertusa were measured in Liaoning coast. The results showed that in dry powder of Ulva pertusa, the protein was 6. 03% , crude fat was 3. 12%, carbohydrate 38. 88%, moisture content 12. 27%, ash content 39. 7, etc. In which the carbohydrate is made up of rhamnose, glucose, xylose, triose, fucose, mannose, galactose, arabinoe etc, measured with gas chromatography. There were many inorganic elements, such as calcium, magnesium, zinc, selenium. The results indicate that Ulva pertusa is rich in nutritive components and can be developed into valuable function food.

Objective To investigate trend of dietary nutrient intake among adult females in China. Methods The changes of dietary energy and major nutrient intake among females aged 25 to 55 years in 9 provinces were analyzed by using the data from Chinese Health and Nutrition Survey,2000-2011 (CHNS) and indicators of Chinese Dietary Reference Intakes (DRIs) 2013. Results During the past decade,the proportion of females with the intake of energy and protein meeting the requirement of recommendation decreased,while the proportion of females with low carbohydrate(<50%energy)and high fat(>30%energy)intakes increased. Meanwhile,the vitamin and mineral intakes among the females were also unsatisfactory,only small proportion of the females met the requirement for micronutrient intake,and this proportion continued to decline. In 2011,the proportion of the females who met the requirements for energy and protein intakes were 43.0% and 54.4%,respectively;the proportion of the females with low carbohydrate and high fat intakes were 40.2%and 63.8%,respectively;the proportion of females who met the requirements for vitamin A, thiamine,riboflavin,niacin,vitamin C and vitamin E intakes were 25.2%,10.7%,6.9%,54.9%,24.3%and 88.5% respectively and the proportion of females who met the requirements for calcium, magnesium,iron,zinc and selenium intakes were 3.3%,23.6%,50.9%,75.7%and 13.3%respectively. Conclusion Further nutritional education and intervention is needed to improve nutrition status among Chinese females.
4.Association between acute stress response and peer bullying behaviors among middle school students
Chinese Journal of School Health 2022;43(10):1462-1466
Objective:
To explore the association between acute stress response during the outbreak of COVID 19 and peer bullying behaviors during the normalized management of COVID 19 among middle school students, and to provide a basis for developing relevant measures for peer bullying prevention.
Methods:
In December 2020, a total of 2 219 students from two junior middle schools in South Anhui(Xuancheng City) and North Anhui(Huaibei City), were selected to participate in this study by using the cluster sampling method. The occurrence of verbal bullying, relational bullying, physical bullying and cyberbullying behaviors among victims and perpetrators of bullying, and self rated acute stress response during the outbreak of COVID 19 (social isolation) were investigated. Multiple Logistic regression models were conducted to explore the relationship between different levels of acute stress response during the COVID 19 outbreak and peer bullying behaviors among middle school students.
Results:
The reported rate of peer bullying, being bullied by others and bullying others during the COVID19 normalized management were 65.8%, 63.8% and 27.1%, respectively. The reporting rate of verbal bullying victimization was the highest (54.8%) and cyberbullying others was the lowest (4.6%). The mean score of acute stress response among middle school students during the COVID 19 outbreak was (6.50±1.67). Except for physically bullying others, the reported rate of other bullying behaviors was the highest in the high level acute stress response group ( P <0.05). Multiple Logistic regression models showed that high levels of acute stress response were associated with high risk of verbal bullying victimization ( OR =1.38), relational bullying victimization ( OR =2.28), physical bullying victimization ( OR =1.87) and cyberbullying victimization ( OR =2.30) after adjusting for related confounders. In the high level acute stress response group, verbal bullying ( OR =1.80), relational bullying ( OR =1.99), physical bullying ( OR =1.76) and cyberbullying ( OR =2.32) had higher risks of bullying others than in the low level acute stress response group ( P <0.05).
Conclusion
High levels of acute stress response are associated with different peer bullying behaviors, with stronger associations with cyberbullying.

CONCLUSIONFurther nutritional education and intervention is needed to improve nutrition status among Chinese females.

Objective To investigate the effects of different types of tricuspid regurgitation, implantation positions, and device models on the treatment outcomes of K-Clip for tricuspid regurgitation using numerical simulations. Methods Three-dimensional reconstruction of the heart model was performed based on CT images. Two different regurgitation orifices were obtained by modifying the standard parameterized tricuspid valve leaflets and chordae tendineae. The effects of different K-Clip models at different implantation positions (posterior leaflet midpoint, anterior-posterior commissure, anterior leaflet midpoint, posterior septal commissure) were simulated using commercial explicit dynamics software Ls-Dyna. Conclusion For the two types of regurgitation in this study, clipping at the posterior leaflet midpoint resulted in a better reduction of the regurgitation orifice (up to 75% reduction in area). Higher clamping forces were required for implantation at the anterior leaflet midpoint and posterior septal commissure, which was unfavorable for the smooth closure of the clipping components. There was no statistical difference in the treatment outcomes between the 18T and 16T K-Clip components, and the 16T component required less clamping force. Therefore, the use of the 16T K-Clip component is recommended.
