Short-term Impact of Cognition-Motivation-Emotional IntelligenceResistance Skills Program on Drug Use Prevention for School Students in Wuhan,China

Drug abuse continues to be a serious public health threat worldwide.Most drug abuse prevention research has been conducted with predominantly American or European adolescent populations.Little is known about approaches that work best to prevent the initiation of Chinese adolescent drug use.For targeting risk factors of drug initiation in Chinese adolescents,a school-based health intervention program named "Cognition-Motivation-Emotional IntelligenceResistance Skills" (CMER) was developed to enhance cognition upon drug use,to decrease motivation of drug use and to improve emotional adjusting and drug resistance skills in this study.A total of 798 students from 3 senior high schools in Wuhan,a city in central China,were assigned randomly to intervention and control groups.The intervention group received the CMER program in which knowledge,development of positive attitude and motivation towards drugs and training of peer resistance skills were basic elements.The immediate impact was compared by measuring the above mentioned elements prior to and three-month after the training session.Students from both groups were asked to complete a self-administered questionnaire.The questionnaire included demographic items,self-reported drug use behavior,cognition,attitude,and motivation associated with the initiation of drug use and resistance skills.Three months after the intervention,significant effects were found on "illegal substance use at least once" (P【0.05) between the intervention and control groups.Immediate effects of the intervention were also found on knowledge,motivation and peer resistance skills (P【0.05),but there was no clear evidence for any effects on attitude towards substance use (P】0.05).It was concluded that the CMER program,which significantly increased the knowledge of drugs and peer resistance skills,was effective in the drug abuse prevention in a sample of school students in Wuhan,China.

Screening of Saprolegniasis Preventive Drugs for Golden Trout (Oncorhynchus mykiss) Fertilized Eggs During Hatching

In order to screen the effective preventive drugs for saprolegniasis occurred during hatching of the fertilized eggs of golden trout, effects of two kinds of self-made Chinese herbal compounds（AB） and two kinds of chemical bactericides（peroxyacetic acid andhydrogen peroxide, CD） with three disinfection concentrations were compared in this study. The fertilized eggs of golden trout were randomly divided into 13 groups, each group with two parallels of 1 000 eggs. Drugs at high,medium and low concentration were respectively used to immerse the fertilized eggs35 min for disinfection once a day. The numbers of live and dead eggs were recorded each day before disinfection and the numbers of survival eyed eggs were counted in each experimental group after finishing the whole test. The results indicated that all of four kinds of drugs used here had a certain effect on prevention and control of saprolegniasis during hatching of fertilized eggs of golden trout, and also showed a correlation between the concentrations and effects. After the selection of several drugs, we found that group B-medium, C-medium and D-high exhibited the most remarkable effects on control of saprolegniasis. However, careful consideration should be given to chemical drugs residues and their potential hazard to the eyed eggs. Therefore, Chinese herbal compound B was suggested to be used for prevention and control of saprolegniasis to achieve the healthy aquaculture. And the concentration and operation time of Chinese herbal compound B should be strictly controlled when used in disinfection of fertilized eggs.

A Unified Decision-Making Technique for Analysing Treatments in Pandemic Context

The COVID-19 pandemic has triggered a global humanitarian disaster that has never been seen before.Medical experts,on the other hand,are undecided on the most valuable treatments of therapy because people ill with this infection exhibit a wide range of illness indications at different phases of infection.Further,this project aims to undertake an experimental investigation to determine which treatments for COVID-19 disease is the most effective and preferable.The research analysis is based on vast data gathered from professionals and research journals,making this study a comprehensive reference.To solve this challenging task,the researchers used the HF AHPTOPSIS Methodology,which is a well-known and highly effective MultiCriteria Decision Making(MCDM)technique.The technique assesses the many treatment options identified through various research papers and guidelines proposed by various countries,based on the recommendations of medical practitioners and professionals.The review process begins with a ranking of different treatments based on their effectiveness using the HF-AHP approach and then evaluates the results in five different hospitals chosen by the authors as alternatives.We also perform robustness analysis to validate the conclusions of our analysis.As a result,we obtained highly corroborative results that can be used as a reference.The results suggest that convalescent plasma has the greatest rank and priority in terms of effectiveness and demand,implying that convalescent plasma is the most effective treatment for SARS-CoV-2 in our opinion.Peepli also has the lowest priority in the estimation.
