RESUMO
Objective Meta-analysis was used to evaluate the effect of the solution-focused brief therapy on im-proving the anxiety and depression status of patients with HIV/AIDS.Methods Computer search of PubMed,Embase,Web of Science,Cochrane Library,CINAHL,PsycINFO,Chinese Biomedical Literature Database,China Na-tional Knowledge Infrastructure,Wanfang Database,CQVIP were conducted,and the search time frame was from the establishment of databases until April 9,2023.There were 2 investigators who independently screened the literature according to inclusion and exclusion criteria,extracted data and performed quality evaluation,and performed Meta-analysis using RevMan 5.4 software.Results A total of 11 publications were included,including 9 randomized controlled trials and 2 quasi-experimental studies,with a total of 1 219 patients with HIV/AIDS.Meta-analysis re-sults showed that solution-focused brief therapy reduced anxiety scores(SMD=-1.89;95%CI:-2.79～-0.99,P＜0.001),depression scores(SMD=-2.45;95%CI:-3.51～-1.39,P＜0.001).Subgroup analysis showed that improved anxiety(SMD=-4.16;95%CI:-7.97～-0.35,P＜0.001),depression(SMD=-5.69;95%CI:-11.20～-0.19,P＜0.001)in pregnant HIV/AIDS patients was significantly better than that in ordinary patients.Conclusion Solution-focused brief therapy is effective in improving anxiety and depression levels in patients with HIV/AIDS,and the application of this model in pregnant patients with HIV/AIDS has a more significant improvement effect,but high-quality,multicenter,large-sample clinical trial studies are needed to further confirm this conclusion in the future.
RESUMO
Bone biomineralization is well-regulated processes mediated by extracellular matrix proteins. The materials that can direct nucleation of hydroxylapatite (HAp) crystals and assembly of well-structured material-minerals complex are the key to mimicking the natural mineralization. This study used sericin from Antheraea pernyi (A.pernyi), non-mulberry silkworm cocoon as template to mediate nucleation of HAp crystals. Here we find out that AS (Antheraea pernyi sericin) can nucleate the formation HAp crystals in simulated body fluid verified by XRD and FTIR observations. The HAp crystals are organized into nano-rods oriented with c-axis preferentially parallel to the long axis of AS due to hydrogen bonds and electrostatic interaction and finally aggregated into HAp globule. The cell culture of human bone marrow-derived mesenchymal stem cells (BMSCs) showed that the HAp crystals mediated by AS not only stimulate cell adhesion and proliferation but also promote 0f osteogenic differentiation, suggesting that the resultant mineralized AS biomaterial has potential in promoting bone formation. Thus our work will provide significant implication on biomineralization of A. pernyi silk sericin as a potential scaffold for tissue engineering.
