RESUMO ANTECEDENTES a correlação entre o aumento do nível de proteínas de ferro no soro e o infarto agudo do miocárdio (AMI) continua controversa. O objetivo desta análise é confirmar a relação entre o aumento dos níveis de proteínas de ferro no soro y o AMI. METODOLOGIA busca de artigos sobre Pubmed e a infraestrutura nacional de conhecimentos da China (cnki) para avaliar a relação entre a proteína de ferro no soro e o infarto agudo do miocárdio, incluída a proteína de ferro no soro e o infarto agudo de miocárdio, até 13 de fevereiro de 2019. RESULTADO foram identificados 11 estudos para sua analise e todas as análises resumidas tiveram base em modelos de efeitos aleatórios. Foram utilizados mapas florestais para mostrar as margens, foi utilizado o índice 12 para examinar a heterogeneidade dos estudos e foram utilizados mapas de funil para avaliar os desvios publicados.A diferença entre a norma de fusão dos níveis de proteína de ferro do Grupo ami e o Grupo de controle é de 0,78 (intervalo de confiança de 95% 0,68-0,88). CONCLUSÃO nos resultados das análises da meta indicam que os pacientes com infarto agudo do miocárdio têm proteínas de ferro superiores às do Grupo de controle de saúde.

SUMMARY BACKGROUND An association between increased serum ferritin levels and acute myocardial infarction (AMI) remains controversial. The purpose of this meta-analysis is to confirm the association between increased serum ferritin levels and AMI. METHODS We searched PubMed and China National Knowledge Infrastructure (CNKI) for relevant articles that assessed the association between serum ferritin and acute myocardial infarction using terms that included serum ferritin and acute myocardial infarction up to February 13, 2019. RESULTS A total of 11 studies were identified for analysis. All pooled analysis was based on a random-effects models. The variance was exhibited using a forest plot, and the heterogeneity among studies was examined using the I2 index, the publication bias was evaluated using a funnel plot. The pooled standard mean difference of ferritin levels between AMI and controls was 0.78 (95%CI,0.68-0.88). CONCLUSION The results of this meta-analysis demonstrate that serum ferritin in acute myocardial infarction patients is higher than that of healthy controls.

Objective: to assess the relationship between serums vitamin D level and type 1 diabetes mellitus (T1DM) in children. Methods: the following electronic databases were searched until Sep 2014 to identify relevant studies that assessed the relationship between serum vitamin D with T1DM: PubMed\EMbase\Medline\Central Register of Controlled Trials\CBM\Chinese National Knowledge Infrastructure (CNKI)\wangfang; The NOS scale was used to evaluate the quality of studies, and the statistical tests were performed by Stata 11.0 software. Result: a total of 10 studies were included in this study. Our results showed that serum vitamin D was significantly lower in children with T1DM than in healthy controls (MD = -0.60, P < 0.05). No evidence support publication bias in present study. Conclusion: the meta-analysis suggests that serum vitamin D level is associated with T1DM in children.

Objetivo: evaluar la relación entre sueros de vitamina D y la diabetes mellitus tipo 1 (T1DM) en niños. Métodos: fueron utilizadas las siguientes bases de datos electrónicas hasta septiembre de 2014 para identificar los estudios que evaluaron la relación entre la vitamina D y la T1DM: PubMed, EMBASE, MEDLINE, Central Register of Controlled Trials, CBM, China National Knowledge Infrastructure (CNKI), wangfang; las enmiendas a la escala se utilizan para evaluar la calidad de los estudios, y los ensayos estadísticos fueron realizados mediante el software Stata 11.0. Resultado: fueron incluidos un total de 10 estudios. Nuestros resultados mostraron que los niveles séricos de vitamina D fueron significativamente menores en los niños con T1DM que en los controles sanos (MD = -0,60, P < 0,05). No hay evidencia de sesgo de publicación en el presente estudio. Conclusión: el metaanálisis sugiere que la vitamina D está asociada con la T1DM en niños.

Zero-strain anode material of Li4Ti5O12 for lithium ion battery was successfully synthesized via the rheological phase reaction (RPR) method. The as-prepared powders were characterized by means of powder X-ray diffraction (XRD), scanning electron microscope (SEM) and particle size distribution analysis (PSD), and the electrochemical properties of the powders were evaluated by the galvanostatic discharge test and cyclic voltammetry (CV). The results revealed that well-crystallized uniform micro-sized Li4Ti5O12 powders were obtained at 800°C for different calcination times via the simple template-free rheological phase route. Among these RPR-derived Li4Ti5O12 powders, one synthesized at 800°C for 22 h displays the initial discharge capacity of 184.3 mAh/g and excellent characteristic of cyclic voltammetry.
