ABSTRACT
Objective:To review relevant research on the application of self-help intervention model in adult depression patients, analyze the main characteristics and application effects of self-help intervention model, in order to provide reference for related research in this field.Methods:According to the methodological framework of the scope review, searched 12 Chinese and English databases including CNKI, Wanfang, PubMed, Web of Science, etc. from the establishment of the database until April 20, 2021, and sorted and analyzed the obtained documents according to the inclusion and exclusion standards.Results:A total of 45 documents were included, of which only 5 were from China; the included studies were mainly based on the Internet platform, using cognitive behavioral therapy, reading therapy, acceptance and commitment therapy, and problem-solving therapy for intervention; the duration of the intervention was 3 weeks to 4 months, participants complete an intervention module or read a specified number of chapters every 3 to 7 days on average, and receive regular guidance and supervision from the intervention facilitator every 1-2 weeks. The total contact time with the facilitator was 80-160 minutes. Various modes of self-help intervention based on the Internet could effectively improve the negative emotions of patients with depression.Conclusions:The self-help intervention model has shown good results in the treatment of patients with depression, but there is a lack of local intervention research in China, and there is no clear standard for the number of interventions and the length of the intervention guide. Under the general trend of "Internet + medical health", it is necessary to actively construct a self-help intervention model for depression with Chinese cultural characteristics, and form a systematic and standardized intervention strategy to address the many obstacles in time, location, resources and cost of people with depression, and finally achieve the purpose of improving the patients′ depressive symptoms and helping them to restore their social functions.
ABSTRACT
The gold hollow nanospheres have been synthesized by sacrificE-template method and the obtained sample has been characterized by TEM, SEM and XRD. The amperometric formaldehyde gas sensor was assembled with gold hollow nanospheres as the active electrode material and 1 mol/L KOH solution as electrolyte. The equation of linear regression(y=16.63x+4.063×10-7, r=0.9989)between the oxidation current(y(A))and the concentration of formaldehyde(x/(mol/L)) was obtained at the formaldehyde concentration in the range of 0 to 2.23×10-6 mol/L. The sensitivity of the sensor with gold hollow nanospheres as active material increased by about 70% compared with the sensor made of nanoparticles which had the same gold-loading in the work electrode, this method exhibits an advantage of decrease in the cost of the noble metal. This kind of sensor shows potential application in formaldehyde gas detection in this range due to its excellent sensitivity, stable response and good linear relationship.
