The power of knowledge: How mental health literacy can overcome barriers to seeking help.

Mental health literacy (MHL) predicts help-seeking attitudes. However, the relationship between components of MHL and help-seeking attitudes has not been thoroughly examined. This study aims to examine whether mental illness stigma, help-seeking efficacy, and maintenance of positive mental health mediated the relationship between recognition of mental disorders and help-seeking attitudes, using a meta-analytic structural equation modeling (MASEM) approach. A comprehensive literature search was conducted to gather relevant studies (111 articles with 118 independent samples), and their data (k = 185) were analyzed using MASEM. Reducing mental illness stigma or increasing help-seeking efficacy may be effective strategies for promoting help-seeking behaviors among individuals who recognize mental disorders, while the maintenance of positive mental health did not significantly mediate the relationship between recognition of mental disorders and help-seeking attitudes. These findings suggest that reducing stigma or increasing help-seeking efficacy may be an effective strategy for promoting help-seeking behaviors among individuals who can identify mental disorders. The use of MASEM in this study highlights the importance of integrating multiple studies to understand the complex relationship between MHL components and help-seeking attitudes.

[Response surface analysis for the optimization of extraction condition for polysaccharides from Epimedium polysaccharides and studies on its tumor immune activities].

To enhance the efficiency of the extraction for Epimedium koreanum Nakai polysaccharides, we conducted the Box-Benhnken experiment and examined the response surface. C57 BL6 mice were used as Lewis-bearing mice model in the study of the polysaccharides in the regulation of tumor immunity. In the first place, different factors including extraction time, temperature, and ratio were evaluated in the yield of polysaccharides. The second order polynomial equation was formed to fit the experimental data. The optimal condition was temperature 87 ℃, extraction time 3.84 h, and ratio of solution and material 1:16.33 to get polysaccharides from Epimedium koreanum Nakai. Under this condition, model-predicted and experimentally measured values of polysaccharide yield were 1.045% and 1.023%, respectively, with a relative error between them at 2.15%. The extraction method is reliable, simple and applicable to the extraction of Epimedium polysaccharides. In addition, this data suggests that Epimedium polysaccharides have obvious immune-regulatory activities in the tumor-bearing mice through increasing the immune-enhancing cytokines to override the immune- suppressing factors.
