Objective To study the expression of adhesion molecule glycoprotein(CD_(44)) in children with primary nephrotic syndrome(NS) and its clinical significance.Methods The expression of CD_(44) in peripheral blood was detected in 28 children with NS by flow cytometry,controlled by 20 cases of healthy children.Results The CD_(44) expression level of NS in active stage was significantly higher than that of the control(P

Objective To investigate the action and mechanism of NF-κB pathway in up-regulating B cell-activating factor receptor (BAFF-R) expression in multiple myeloma cells induced by IFN-γ.Methods Activated NF-κB were detected with Western blot, while the expression of BAFF-R were measured with RT-PCR and ELISA, and investigated the effect of BAY11-7082 on transcription of BAFF-R mRNA and translation of protein in multiple myeloma cells stimulated by IFN-γ. Results IFN-γ can induce the degradation of IκB-α in time-dependent and dosage-dependent manner, and up-regulated BAFF-R expression in multiple myeloma cells. BAY11-7082, an NF-κB inhibitor, inhibited not only the transcription of BAFF-R mRNA but also the protein of regulated by IFN-γin dosage-dependent manner. Conclusion NFκB may play an important role in high expression of BAFF-R in multiple myeloma cells induced by IFN-γ.

Objective To assess the capability of monochromatic energy images of Gemstone spectral imaging(GSI) in reducing artifacts caused by metallic implants. Methods Twelve subjects with metallic implants underwent GSI (Discovery CT750 HD, GE Healthcare, Milwaukee ). The metallic orthopedic implants included 3 patients of dentures, 2 patients of cervical spinal vertebraplasty, one clavicle fracture fixation, one lumbar spinal vertehraplasty, 3 patients of artificial femoral head, one iliac fracture fixation and one tibial fracture fixation. GSI was performed by using a single source ultra-fast dual energy X-ray switching (80 kVp and 140 kVp). Following GSI scanning, thin slice images were reconstructed into 1.25 mm slice thickness. The monochromatic energy images were set to the same window width and level (window width 1500 HU,window level 500 HU). The artifact indexes (AI) at different kiloelectronvolts (keV) images were measured and compared. 3D reconstruction was performed using images with minimal AI. Result The artifacts index on monochromatic energy images varied with the change of keV. Of the images from 12 subjects, the maximal AI ranged between 145-225 at 40 keV, and minimal AI ranged between 15-90 at the 95-140 keV. The artifacts are clearly visible on polychromatic energy images and the artifacts are reduced markedly on the monochromatic energy images with minimal AI. Conclusion The artifacts caused by metallic implants can be reduced significantly by GSI with high keV monochromatic energy images.

OBJECTIVETo determine the changes in fecal Bifidobacterium species in patients with type 2 diabetes in comparison with healthy individuals.

METHODSThe bacterial DNA were extracted from the fecal samples from 50 type 2 diabetic patients and 30 healthy individuals. Real-time quantitative PCR was employed to determine the copy numbers of the bacteria in the fecal samples using 16S rRNA-targeted genus- and species-specific PCR primers for a selected group of fecal Bifidobacterium species including total Bifidobacterium, B.longum, B.breve, B.adolescent, and B. infantis.

RESULTSThe diabetic group had significantly lower copy numbers of total Bifidobacterium and B.adolescent compared to the healthy individuals (P<0.05).

CONCLUSIONType 2 diabetic patients have a lowered number of Bifidobacterium species in the gut microflora.

Coronary artery disease (CAD) is a chronic disease but causes the highest mortality and morbidity among the cardiovascular diseases worldwide. Correlations between CAD and gut microbiota have been observed. This suggests that the gut microbiota could become a vital diagnostic marker of CAD, and restoring the gut habitat may become a promising strategy for CAD therapy. The elevated level of trimethylamine-N-oxide (TMAO), a gut microbiota-derived metabolite, was found to be associated with the increased risk of cardiovascular disease and the all-cause mortality. Preclinical studies have shown that it has pro-arteriosclerosis properties. It is likely that regulating the production of TMAO by gut microbiota may become a promising strategy for anti-atherosclerosis therapy. This review summarizes the clinical and preclinical researches on the intervention of CAD by regulating the gut microbiota and the microbiota-derived metabolite TMAO, with the aim to provide new target for the therapy of CAD.
