Objective To investigate the effects of a novel synthetic immunostimulator CH2b containing thiazolidin-4-one on the function of invariant nature killer T (iNKT) cells isolated from patients with active rheumatoid arthritis (RA).Methods Peripheral blood mononuclear cells (PBMCs) isolated from patients with active RA were in vitro cultured with α-Galcer and IL-2.The iNKT cells were separated by using magnetic activated cell sorting (MACS) method.The effects of CH2b on the proliferation of iNKT cells were analyzed by using MTT assay.MILLIPLEX MAP Human Cytokine/Chemokine kit was used to measure the levels of IFN-γ and IL-4 in the supernatants of iNKT cell culture.The expressions of IFN-γand IL-4 at mRNA level in iNKT cells were analyzed by RT-PCR.Western blot assay was used to detect the levels of T-bet and GATA-3 in iNKT cells.Results CH2b significantly enhanced the proliferation of IL-2 activated iNKT cells isolated from the patients with active RA.CH2b promoted the secretion of IL-4,resulting in a decrease in the ratio of IFN-γ/IL-4.Moreover,CH2b promoted the expressions of GATA-3 and IL-4 at mRNA level in iNKT cells.Conclusion The novel immunostimulator,CH2b,might enhance the immunoregulatory effects of iNKT cells by promoting the GATA-3 pathway-mediated secretion of Th2-1ike cytokines and inducing the differentiation of Th0 to Th2 cells.

Objective To investigate the metabolic changes and the metabolites distribution of different hippocampal regions (head,body and tail)in patients with Alzheimer’s disease (AD)using 1 H-MRS for early diagnosis.Methods The hippocampal multivoxel 1H-MRS at 3.0 T was scanned in 30 patients with AD and other 30 normal cognitive elders (NC)as contrast.The data obtained were processed at a workstation.The hippocampus was divided into 3 parts (head,body and tail),and the ratios of N-acetylaspartate (NAA)/creatine (Cr),myoinositol (MI)/Cr and MI/NAA were calculated respectively.The metabolite ratios and distribution changes were compared between group AD and NC.Results Compared with the group NC,the NAA/Cr in group AD in bilateral hippocampal body and tail was decreased,whereas the MI/Cr and MI/NAA in bilateral body and tail,MI/NAA in left head were opposite (P<0.01).In group NC,the NAA/Cr was gradually decreased from the bilateral hippocampal heads to tails (P<0.01),however,the MI/NAA was opposite (P<0.01).No distribution differences in every metabolic ratios of bilateral hippocam-pus were found in AD group (P>0.05).Conclusion Metabolic changes and disappearance of the normal distribution in different hippocampal regions detected by 1 H-MRS provide helpful clues for early diagnosis of the AD.

Objective To explore the effect and mechanism of relaxin on the production of extracellular matrix (ECM) excreted by high glucose stimulated human renal mesangial cells.Methods Cultured human mesangial cells (HMCs) were divided into three groups:(1) normal glucose group (NG,5.5 mmol/L D-glucose),(2) high glucose group (HG,30 mmol/L D-glucose),and (3) high glucose + relaxin group.Cell count kit (CCK8) was used to examine the cell proliferation.The levels of fibronectin and collagen type Ⅳ in the culture supernatants were examined with a solid-phase enzyme-linked immunoadsorbent assay (ELISA);Western blot method was used to detect the expression of α-smooth muscle actin (α-SMA) protein.The transforming growth factor-β1 (TGF-β1) mRNA expression was detected with quantitative polymerase chain reaction (qPCR) method.Results No proliferation and inhibition effects were observed in both normal and high glucose group.Compared to the normal glucose group,the levels of fibronectin,and collagen type Ⅳ increased significantly (57.28 ± 0.59 vs 41.85 ± 0.03,56.52 ± 0.88 vs 33.80 ± 0.24,P ＜ 0.01)after cultured 48 h in high concentration of glucose.Compared to the high glucose group,a significantly decreases of fibronectin and collagen type Ⅳ (47.08 ± 0.03 vs 57.28 ± 0.59,36.16 ± 0.52 vs 56.52 ±0.88,P ＜0.01) were observed in the relaxin treated group.The expressions of α-smooth muscle actin and TGF-β1 were decreased (P ＜0.01).Conclusions Relaxin can suppress the overproduction of ECM excreted by HMC cultured in high ambient glucose,and its mechanism is partly due to the inhibition of TGF-β1.
