Imaging findings of cerebral small vessel diseases (CSVD) include white matter lesions,enlarged perivascular spaces,lacunar infarcts and cerebral microbleeds.These imaging markers often appear at the same time.In recent years,the "total small vessel diseases score" was proposed by combining the different magnetic resonance imaging (MRI) markers into one measure of CSVD,so that we can capture all the brain damage from CSVD more accurately through the evaluation of total MRI burden.This paper reviews the research progress of total small vessel diseases score and its application.

OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNPs) of microRNA-146a (miR-146a) with clinical features of rheumatoid arthritis (RA). METHODS: In 126 patients with RA and 102 matched healthy controls, SNPs of miR-146a rs2910164 locus were determined with a high-resolution melting method. The association of such polymorphisms with disease activity score in 28 joints (DAS28) and clinical features of RA was assessed. RESULTS: The distribution of SNPs of miR-146a rs2910164 among RA patients did not differ from that of the control group. No significant association was found between miR-146a rs2910164 polymorphism with DAS28. However, RA patients with a GG genotype had a greater chance to develop extra-articular manifestations (P<0.01). CONCLUSION Polymorphisms of miR-146a rs2910164 locus is not an independent risk factor for RA, though its GG genotype may be associated with extra-articular manifestations of RA.
