We carried out metagenomic shotgun sequencing and a metagenome-wide association study (MGWAS) of fecal, dental and salivary samples from a cohort of individuals with rheumatoid arthritis (RA) and healthy controls. Concordance was observed between the gut and oral microbiomes, suggesting overlap in the abundance and function of species at different body(More)
Primary Sjögren's syndrome is one of the most common autoimmune diseases. So far, genetic studies of Sjögren's syndrome have relied mostly on candidate gene approaches. To identify new genetic susceptibility loci for primary Sjögren's syndrome, we performed a three-stage genome-wide association study in Han Chinese. In the discovery stage, we analyzed(More)
Id1, a member of Id family of helix-loop-helix transcriptional regulatory proteins, is implicated in cellular senescence by repressing p16(INK4a) expression, but the mechanisms and cellular effects in human diploid fibroblasts remain unknown. Here we analyzed the patterns of p16(INK4a) and Id1 expression during the lifespan of 2BS cells and presented the(More)
Spirulina platensis exposed to various selenium (Se) concentrations (0, 10, 20, 40, 80, 150, 175, 200, 250 mg/L) accumulated high amounts of Se in a dose- and time-dependent manner. Under low Se concentrations (<or=150 mg/L), Se induced increases in biomass concentration, content of photosynthetic pigments, and activities of glutathione peroxidase (GPX),(More)
A PCR detection based on 16S-23S rDNA internal transcribed spacer (ITS) of Klebsiella pneumoniae was developed in the present study. Nineteen different ITS sequences were amplified from 6 strains of K. pneumoniae by universal primers. By sequencing and alignment of these sequences to the other homologous in GenBank, species-specific primers of K.(More)
To investigate the clinical features of adult patients with hemophagocytic lymphohistiocytosis (HLH) and to explore possible risk factors for death, we retrospectively reviewed the medical records of 103 adult HLH patients hospitalized from 1997 to 2012. We analyzed the underlying diseases, clinical characteristics, laboratory findings, outcomes, and(More)
PURPOSE To evaluate the differences of learning curve for PELD depending on the surgeon' s training level of minimally invasive spine surgery. METHODS We retrospectively reviewed the medical records of 120 patients (surgeon A with his first 60 patients, surgeon B with his first 60 patients) with sciatica and single-level L4/5 disk herniation who underwent(More)
OBJECTIVE Protein-losing enteropathy (PLE) is an unusual manifestation of systemic lupus erythematosus (SLE), so its clinical manifestations and management are not well understood. In this study, we try to characterize the basic clinical features and the management of PLE by retrospectively analyzing the clinical data of 15 PLE patients and hope this study(More)
The purpose of this study was to compare the causes and characteristics of reoperations after different primary operations for lumbar disc herniation (LDH). Out of a series of 5,280 patients who underwent operations for LDH between 2001 and 2012, 207 patients (135 male and 72 female, mean age 47.7 years) underwent primary and revision operations, which were(More)
Ruthenium(II) methylimidazole complexes, with the general formula [Ru(MeIm)(4)(N⌢N)](2+) (N⌢N = tip (RMC1), iip (RMC2), dppz (RMC3), dpq (RMC4); MeIm = 1-methylimidazole, tip = 2-(thiophene-2-yl)-1H-imidazo [4,5-f] [1,10]phenanthroline, iip = 2-(1H-imidazol-4-yl)-1H-imidazo [4,5-f] [1,10]phenanthroline, dppz = dipyrido[3,2-a:2',3'-c]phenazine, dpq =(More)
