ABSTRACT
College students, as an important talent reserve of national social development and the family’s future hope, their actions will bring greater influence to ordinary social groups. By analyzing the information demand of people in public health emergencies and the way of transmitting the disposal information of college students to the people, this paper studied the disposal behaviors of college students during the epidemic prevention and control period, such as information collection and feedback, emotional expression, behavioral norms and information dissemination. It was found that the behavior of college students in dealing with public health emergencies has a certain demonstration and guiding effect on society. In view of this effect, this paper put forward some educational activities, such as rational information analysis, effective relief of emotions, scientific analysis of the present situation, and positive dissemination of network information, so as to expand the demonstration function of college students in dealing with public health emergencies.
ABSTRACT
Objective:To study the degree of recognition about the protection of traditional knowledge of Chi-nese medicine and its influencing factors among Shaanxi University of Chinese Medicine students and provide scien-tific evidence for improving relevant policies.Methods: 1,162 college students were chosen by stratified cluster sampling from Shaanxi University of Chinese Medicine and questionnaires were surveyed among them.Rank sum test and multiple linear regression model were used to explore the related factors on degree of recognition about the protection of traditional knowledge of Chinese medicine.Results: The overall cognition-scoring rate was 36.55％,and subscales in descending order by scoring rate were loss of traditional knowledge of Chinese medicine,international and domestic related protection systems.There were significant differences in scores between age groups,majors,grades,place of origin,family monthly income per capita,parents'educational background,moti-vation of applying for medical school,and whether they had taken the protection of traditional knowledge of Chinese medicine courses(P<0.05).Conclusion:The overall cognition-scoring rate among Shaanxi University of Chi-nese Medicine students was generally low.In order to motivate students to protect traditional knowledge of Chinese medicine and promote a healthy development of Chinese medicine,measures from national institution and school education should be conducted.
ABSTRACT
Through the summary and analysis of the existing problems of contemporary college students' ecological ethics education,such as lack of system of ecological concept education,lack of environmental protection education,lack of ecological practice education and so on,this paper analyzed and found that the main reason for the existence of problems contemporary college students' ecological education lied in the adverse effects of social environment,the rigidity of education way in school and the lack of personal understanding of students three aspects.Thus,in order to improve the effect of college students' ecological ethics education,we must improve the education way and method in view of these three aspects.
ABSTRACT
Aiming at current situation for network ideological and political education in colleges and universities and setting opinion leader theory as entry point,Through the deep analysis of existing real problem of network ideological and political education in colleges and universities,it was found that it must pay more attention to the function of network opinion leader to promote the effects of network ideological and political education in colleges and universities.And also through identifying and cultivating related network opinion leader,it can realize the objective to enhancing the effects of network ideological and political education by right of the influence of network opinion leader.
ABSTRACT
The spirit of contract, with freedom, equality and reciprocity of power and responsibility as basic connotation and containing credit consciousness, is the core content of the concept of rule of law. People′s desire for justice, recognition of fairness, reliance on integrity contained in the concept of rule of law all originate from the spirit of contract, such as contract party's expectation of fairness, performance of obligation, abiding by the valid contract. Not only does the concept of rule of law reflect the essence requirement of the spirit of contract, but also is the external form of realization. Therefore, in order to enhance the concept of rule of law of the college students, it is a certain choice to cultivate the spirit of contract. However, the current paths to cultivate the spirit of contract are mainly theoretical research, environmental influence and system perfection.
ABSTRACT
Objective To observe the effects and mechanism of TNFα and IL-1 on protein catabolism of skeletal muscles of mice in the early stage of severe burn. Methods A BALB/c mice model was established with full thickness scalded of 18%～20% TBSA including the back and one hind limb. The catabolic rate of protein of soleus muscle was reflected with the net tyrosine releasing rate. The changes of the tyrosine releasing rates of the injured and uninjured limbs, the levels of TNFα and IL-1 of the plasma and soleus muscle, and the activities of lysosomal proteolytic enzymes were observed in 72 h after scald injury of the mice. Results After injury, the levels of TNFα and IL-1 of plasma, injured and uninjured limbs were all increased, and reached the summit at the 48th h, but those of the injured limb were much higher than those of the uninjured one, then gradually the levels were decreased in 72 h. The protein catabolic rate of uninjured limb was higher than the normal at h 48, but it came to normal level at h 72. The rate of the injured limb was higher than that of normal and uninjured limbs significantly 72 h after the scalding. hrTNFα and hrIL-1 enhanced the protein catabolic rate and the activities of lysosomal protrolytic enzymes in the soleus muscle of normal mice in vivo and in vitro respectively. Conclusion In the early stage of scald injury, TNFα and IL-1 could enhance the lysosomal protease activity, increase the protein catabolic rate in skeletal muscle and promote the negative nitrogen balance directly. These effects may not depend on the actions of emergent hormones.
ABSTRACT
Objectives:To compare the effect of defferent routes of nutritional support on the 26 S proteasome. Methods:The means of immuno precipitation deduction,ELISA and fluore photomction were used to test the change of activities,contents of the 26 S proteasome and the rate of protein degradation in skeletal muscle of scalding rats with the animal model of enteral feeding and parenteral nutrition. Results:Compared with parenteral nutrition,enteral feeding could markedly reduce the activity and content of the 26 S proteasome,and the release of tyrosine was also lowered. Conclusions:The early enteral feeding can distinctly inhibit the system of 26 S proteasome,and reduce the protein degradation in skeletal muscle in bruned rats.
ABSTRACT
In order to study the role played by infection in the occurrence and mechanism of negative nitrogen balance of the skeletal muscles in the early stage of scalding,37% TBSA full thickness scalding was inflicted on the back and one hind leg of rats and the protein catabolic rate in the soleus muscle of both the scalded and healthy legs was determined and the effects of endotoxin on the catabolic rate were observed.It was found that the protein catabolic rate was markedly accelerated in the scalded soleus 3 days after iujusy;and showed no significant changes in the healthy one,in which the protein catabolic rate was near or similar to that of the normal control.After 2 mg/kg of endotoxin was administered intraperitoneally.the findings were as follows:(1)Endotoxin could also accelerate the protein catabolic rate in the skeletal muscles;(2)The protein catabolic rate in the scalded soleus was not further increased and no summation effect of scalding and endotoxin on protein catabolism occurred.
ABSTRACT
One hind leg(7 %TBSA)of the rat was scalded and the changes of the reduction-oxidation state and protein degradation in the soleus muscle were observed 72 hours postinjury both in vitro and in vivo.It was found that the lactate/pyruvate (L/P) and malate/pyruvate(M/P)ratios of the soleus muscle were significantly lower and the protein degradation rate much higher in the scalded leg than in the unscalded legs and the control.After the addition of insulin to the medium significant elevation of L/P and M/P ratios and reduction of the protein degradation rate in the soleus muscle could be observed.There findings suggest that there is a good correlation between the changes of the reduction-oxidation state and the protein degradation rate in the cytosol of the soleus muscle after scalding in the rat.
ABSTRACT
The effects of exogenous Na-DL-3-hydroxybutyate (3-HOBNa)and insulin(I) on skeletal muscle protein metabolism in rats inflicctcd with 37% TBSA full thickness scalding were studied It was found that the scrum acctoacctatc (AcAc) of the burned animals showed no significant difference from the control on the 4th day postburn,but the free fatty acid (FFA) decreased markedly and the urinary 3 - methylhistididne(3-MH) excretion and the protein de -gradation rate of the soleus muscle of the injured hind limb increased na kedly.Infusion of 3-HOBNa for 3 consecutive days following burns could lower the urinary 3-MH excretion and the protein,degradation rate of the soleus muscle with no significant influence on the skeletal muscle protein anabolism.Moreover,investigations revealed that there was no syncrgistic effect of insulin-kctone body combinalioan on the anti-catabolic capacity in burned rats.
ABSTRACT
To elucidate the mechanism of negative nitrogen balance after burns, immuno precipitation deduction was used to observe the changes in the activity of 26S proteasome and 19S regulator in skeletal muscle of rats inflicted with 30%TBSAⅢ o burns. The protease activity, ATPase activity of 26S proteasome,as well as 19S regulator in skeletal muscle of rats were markedly enhanced on the second day after scald. It is suggested that burn injury could activate the 26S proteasome in skeletal muscle, in turn enhance the degradation of protein , which is associated with negative nitrogen balance following scald
