ABSTRACT
BACKGROUND AND OBJECTIVE: The 12-month follow-up effect of the self-efficacy-focused structured education program (SSEP) requires in-depth confirmation. This study aims to verify whether the benefits of SSEP can be maintained in 12 months. MATERIALS AND METHODS: A multicenter randomized controlled trial with 12-month follow-up conducted among 265 type 2 diabetes patients not on insulin from 4 hospitals in mainland China. The intervention group (n = 133) was administrated with SSEP, and the control group (n = 132) received the routine education. The indicators of metabolic and psychosocial aspects of the patients were assessed at baseline and 12 months. RESULTS: As opposed to the control group, the primary outcomes of HbA1c in the intervention group were improved obviously in the 12th month during the 12-month follow-up (-1.13%, P < 0.001). The secondary outcomes (ie, waist circumference, total cholesterol, low-density lipoprotein cholesterol, diabetes self-efficacy, diabetes self-management behaviors, diabetes knowledge and diabetes distress) were improved significantly in the intervention group as compared with the control group in the 12th month during the 12-month follow-up (-3.14 cm, P = 0.001; -0.30 mmol/L, P = 0.032; -0.25 mmol/L, P = 0.008; 0.87, P < 0.001; 10.67, P < 0.001; 3.42, P < 0.001; -4.97, P < 0.001). The non-significant difference in the secondary outcomes (ie, systolic pressure, diastolic pressure, triglycerides and high-density lipoprotein cholesterol) was identified between the two groups in the 12th month during the 12-month follow-up (P > 0.05). CONCLUSION: The SSEP provided sustainable benefits in outcomes of HbA1c, waist circumference, total cholesterol, low-density lipoprotein cholesterol, diabetes knowledge, diabetes distress, diabetes self-efficacy and diabetes self-management behaviors for type 2 diabetes patients not on insulin in the 12th month during the 12-month follow-up. Thus, it will be an effective education model capable of being generalized nationwide, and it can be referenced for the nations and regions under consistent conditions. CLINICAL TRIAL REGISTRY: Chinese Clinical Trial Registry (ChiCTR-IOR-17011007).
ABSTRACT
Large-scale uniform ZnO dumbbells and ZnO/ZnS hollow nanocages were successfully synthesized via a facile hydrothermal route combined with subsequent etching treatment. The nanocages were formed through preferential dissolution of the twinned (0001) plane of ZnO dumbbells. Due to their special morphology, the hollow nanocages show better sensing properties to ethanol than ZnO dumbbells. The gain in sensitivity is attributed to both the interface between ZnO and ZnS heterostructure and their hollow architecture that promotes analyte diffusion and increases the available active surface area.
ABSTRACT
Despite steady progress in elimination of measles virus globally, measles infection still causes 500,000 annual deaths, mostly in developing countries where endemic measles strains still circulate. Many adults are infected every year in China, with symptoms more severe than those observed in children. In this study, we have used blood samples from adult measles patients in Shanghai and age-matched healthy controls to gain an understanding of the immune status of adult measles patients. IFN-alpha mRNA was reduced in patient PBMC compared with healthy controls. In contrast, gene expression and plasma production of IL-2, IL-10, and IFN-gamma were elevated in patient blood. A similar cytokine profile was observed at early times when cultured PBMC were infected with a clinical isolate of measles virus. In contrast to previous studies in pediatric patients, we did not find a reduction in total CD4(+) and CD8(+) T cells in patient PBMC. Interestingly, we found that CD4(+)CD25(+)CD127(low) regulatory T cells were significantly increased in patient PBMC compared with controls. Using intracellular cytokine staining we also show that the measles virus induces IL-10-producing CD14(+) and CD4(+)CD25(+) cells in PBMC. Our results show that adult measles patients in the acute phase of the disease have a mixed Th1/Th2 type response, accompanied with severe immunosuppression of both innate and adaptive responses including suppression of type I IFN. Both regulatory T cells and plasma IL-10 may contribute to the immunosuppression.
