ABSTRACT
Abstract@#Improving the system of adolescent myopia prevention and control and promoting adolescent healthy development is one of the main directions of healthy China construction in the new era. The paper reviewed national myopia policies and local practices, and proposed reflections on the high burden and complex etiology of myopia among adolescents, as well as unclear role and lack of coordination mandate during the COVID 19 epidemic. Based on the synergy theory, through the analysis of the functional positioning of multiple subjects in the prevention and control of myopia, the paper highlighted the multi party linkage of government, schools, medical institutions, communities, families and markets, profiling the resources and advantages of each subject, as well as dynamic management of adolescent myopia, as well as a multi subject collaborative prevention and control system with national unity, clear rights and responsibilities, and long term cooperation.
ABSTRACT
Abstract Background Brain natriuretic peptide (BNP) and troponin have a close relationship with cardiogenic cerebral embolism (CCE), but their relationship with noncardiogenic patients with anterior circulation ischemia (ACI) and posterior circulation ischemia (PCI) is not clear. Objective To explore the predictive value of serum initial BNP and troponin on the functional prognosis of patients with noncardiogenic ACI and PCI. Methods Consecutive patients with first-episode cerebral infarction within 12 hours of symptom onset were enrolled in the present 1-year prospective cohort study. Serum levels of BNP and troponin were collected within 12 hours of onset. Infarction location was classified as ACI and PCI by magnetic resonance imaging (MRI). According to the modified Rankin Scale (mRS) score at 90 days after onset, ACI and PCI cases were respectively divided into a good prognosis group (mRS score between 0 and 2) and a poor prognosis group (mRS score between 3 and 6). The general state of health and results of laboratory examinations and other auxiliary examinations of all patients were recorded. Single-factor analysis and multivariate logistic regression analysis were used to assess the relationship between serum levels of BNP, troponin, and functional outcome. Results The multivariate logistic regression found that higher levels of initial BNP (odds ratio [OR] = 1.024; 95% confidence interval [CI]: 1.006-1.041; p = 0.007) and C-reactive protein (CRP) (OR = 1.184; 95%CI: 1.024-1.369; p = 0.022) were independent predictors of poor functional prognosis of noncardiogenic PCI at 90 days after onset after adjusting for age, gender, ethnicity, history of hypertension and of diabetes. Conclusions The levels of initial BNP and CRP were related to poor functional outcomes in noncardiogenic PCI patients at 3 months, independent of troponin.
Resumo Antecedentes O peptídeo natriurético cerebral (BNP, na sigla em inglês) e a troponina estão intimamente relacionados com a embolia cerebral cardiogênica (CCE, na sigla em inglês), mas a relação com pacientes não cardioembólicos com isquemia de circulação anterior (ICA) e isquemia de circulação posterior (ICP) não é clara. Objetivo Investigar o valor preditivo dos níveis séricos iniciais do BNP e da troponina no prognóstico de pacientes com AVC isquêmico não cardiogênico. Métodos Os níveis séricos de BNP e de troponina foram recolhidos de pacientes com primeiro episódio de acidente vascular cerebral (AVC) isquêmico dentro de 12 horas após o início dos sintomas, com localização classificada como ICA e ICP de acordo com exame de ressonância magnética (RM). De acordo com a pontuação modificada da escala de Rankin (mRS), aos 90 dias após o início dos sintomas, ICA e ICP foram divididas respectivamente em um grupo de bom prognóstico (mRS entre 0 e2) e em um grupo de mau prognóstico (mRS entre 3 e 6). Foram registrados exames laboratoriais e outros exames complementares de todos os pacientes. Foram utilizadas análise fatorial única e análise de regressão logística multivariada para investigar a relação entre os níveis séricos de BNP e de troponina e o resultado funcional. Resultados A regressão logística multivariada evidenciou que os níveis mais altos de BNP inicial (odds ratio [OR] = 1,024, intervalo de confiança [IC] de 95%: 1,006-1,041; p = 0,007) e proteína C reativa (CRP, na sigla em inglês) (OR = 1,184; 95%CI: 1,024-1,369; p = 0,022) foram preditores independentes de mau prognóstico funcional da ICP não cardiogênica aos 90 dias após o início dos sintomas. Conclusões Os níveis iniciais de BNP e CRP se associaram a maus resultados funcionais em pacientes com ICP não cardiogênica aos três meses, independentemente da troponina.
ABSTRACT
@#Basic fibroblast growth factor (bFGF) exhibits superior biological functions by improving periodontal inflammation, promoting the migration and proliferation of periodontal-related stem cells, promoting the formation of blood vessels and periodontal ligament-like tissue, and regulating the formation of bone/cementum. It plays an important role in tooth development, repair and regeneration. bFGF can be combined with seed cells and scaffold materials for periodontal tissue regeneration, which has been verified in a number of experimental studies. However, the application of bFGF alone as a drug in clinical treatment requires further research.
ABSTRACT
A cDNA clone encoding ribosomal protein S27 (AmphiS27) was identified in the gut cDNA library of amphioxus Branchiostoma belcheri tsingtauense. This cDNA consists of 607 bp and contains a 255 bp open reading frame (ORF) corresponding to a deduced protein of 84 amino acids with a calculated molecular mass of 9,488 Da and an isoelectric point (pI) of 9.500. Alignment of the deduced AmphiS27 amino acid sequence with 12 known S27 protein sequences indicates that AmphiS27 shares 94-99% homology with its vertebrate homologue, 84-94% with invertebrate homologues and 69-72% with homologues from other eukaryotes, suggesting that AmphiS27 is more closely related to the vertebrate S27 protein than to its invertebrate counterpart. Southern blot analysis showed a single copy of the S27 gene present in the genome of amphioxus B. belcheri tsingtauense, indicating that amphioxus has a genome uncomplicated by extensive gene duplication
