Objective To study the genome DNA methylation in rheumatoid arthirits(RA)and the re- lated factors of DNA methylation.Methods Twenty-first cases with RA and 20 controls were recruited to par- ticipate the study.Plasma Hcy,SAM,SAH,the MTHFR gene C677T polymorphism and the expression of LFA-1 in CD4~+T cells was measured in all patients and controls.Results①The SAM levels were lower sig- nificantly in RA groups than in controls.The SAH levels were higher significantly in RA groups than in con- trols.②There was significant inverse correlation between plasma Hcy level and SAM level(r=-0.932,P<0.01). There was significant positive correlation between plasma Hcy level and SAH level(r=0.924,P<0.01).③The expression of LFA-1 in CD4~+T cells was higher significantly in RA groups than in controls.There was a signif- icant positive correlation between LFA-1 expression level and Hcy level(r=0.557,P<0.01),a significant in- verse correlation between LFA-1 expression level and SAM level(r=-0.651,P<0.01).④The MTHFR gene mu- tation lead to dramatically increase of Hcy,SAH level and the expression of LFA-1 level in CD4~+T cells and genome DNA hypomethylation.Conclusion①Hypomethylation of genome DNA is found in most RA pa- tients.②The factors associated with genome DNA hypomethylation include MTHFR gene mutation and hyper- homocysteinemia.③The expression of LFA-1 in CD4~+ T cells is higer in RA groups than in controls,which re- lates to the DNA methylation level and the MTHFR gene C677T polymorphism.

AIM: To investigate the role of retinal pigment epithelium (RPE) in the growth of Müller cells using a co-culture system in vitro . METHODS: Müller cells were cocultured with RPE cells under both normoxic and hypoxic conditions in Transwell chamber culture system. Müller cell proliferation was evaluated by MTT assay. The number of cells which migrate through micropores and stay on the outer bottom side of insert systems were observed and counted. RESULTS: The activities of proliferation and migration of Müller cells when cocultured with RPE cells were significantly higher than those of the Müller cells when cultured alone at all time points under both normoxic and hypoxic conditions. However, for both the coculture and control groups, there is no significant difference between the measurements at 3 and 6 hours. CONCLUSION: Evidence suggests that RPE, when co-cultured with Müller cells, can stimulate migration and proliferation of Müller cells under both hypoxic and normoxic conditions in a time-dependent manner; how-ever, there is no evidence to support the synergetic interaction of RPE and Müller cells co-cultured under hypoxic conditions.

Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.

OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.
METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.
RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).
CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.
