AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

Objective:To valuate the treatment value and analyse the effect on the cellular immune functions by studying the differences of T-lymphocyte subsets and CD4+CD25+Treg cells in peripheral blood after adoptive immunotherapy ( dendritic cells and cytokine-induced killer cells,DC-CIK) combined with chemotherapy on MM.Methods:50 patients with MM were randomly divided into two groups.24 patients in chemotherapy group were treated by chemotherapy only,26 patients in joint group were treated by adoptive immunotherapy( DC-CIK) combined with chemotherapy,and the clinical outcomes and the levels of T-lymphocyte subsets and CD4+CD25+Treg cells in peripheral blood between two groups were compared.Moreover,the differences of cellular immune indicators (Th1/Th2,the ratio of AgNOR,and TGF-β)between two groups were also compared.Results: After treatment,quality of life,clinical index and survival in joint group were better than in chemotherapy group( P<0.05);the proportion of CD3+CD8+,the ratios of CD4+CD25+,CD4+CD25+/CD4+and the level of TGF-βof joint group wes clearly lower than chemotherapy group(P<0.05),and the ratios of CD3+CD4+/CD3+CD8+, Th1/Th2 and AgNOR of joint group wes clearly higher than chemotherapy group .Conclusion: DC-CIK combined with chemotherapy could be an effective and promising treatment to patients with MM,and it maybe strengthen the anti-tumor action of bodies by regulating the balance between Th1 and Th2 reaction.

Objective:To evaluate the expression of CXCR4 and the migration rate of bone marrow stromal CD34+cells in differ-ent risk groups with myelodysplastic syndromes (MDS) using correlation analysis. Methods: Forty MDS patients were divided into low-and high-risk groups based on the International Prognosis Scoring System (IPSS). The former was composed of 20 patients with IPSS<1.5, whereas the latter was composed of 20 patients with IPSS≥1.5. Bone marrow (BM) samples of these patients and 10 nor-mal controls were collected. CD34+cells were separated and purified. The expression of CXCR4 was determined by flow cytometry. The migration rate of CD34+cells on the chemotactic effect of SDF-1αand on the effect of bone marrow stromal cells were measured. Results:The expression rate of CXCR4 was higher in the high-risk MDS group than in the low-risk and control groups (P<0.000 1). No significant differences existed between the low-risk and the control groups (P>0.05). The migration rate of CD34+cells on the ef-fects of SDF-1αand marrow stromal cells were significantly increased in the high-risk MDS group compared with those in the low-risk and control groups (P<0.000 1). Migration rate of CD34+cells on the effect of marrow stromal cells was positively correlated with CX-CR4 expression (P=0.000 1). Conclusion:The CXCR4 expression and migration rates of CD34+cells on the effect of marrow stromal cells are significantly higher in the high-risk MDS group than in the low-risk group. Migration rate has a positive correlation with the CXCR4 expression, which further indicates that MDS is a heterogeneous group of hematopoietic stem cell malignancies. The expres-sion and function of SDF-1 and its receptor CXCR4 differ within each group with various risks. SDF-1 and CXCR4 may be involved in MDS pathogenesis.

Aim To investigate the reversal effect of vatalanib, a novel kinase inhibitor, on multidrug re-sistance in cancer cells and its mechanism. Methods The cytotoxicity and reversal effects of vatalanib were evaluated in both resistant and sensitive tumor cell lines by MTS or SRB assays. The intracellular accumu-lation of fluorescence substrates ( Rh-123 , MX and ADR for P-gp, BCRP, MRP1, respectively) were ana-lysed by flow cytometry. Western blot or qRT-PCR was
used to determine the protein or mRNA expression lev-el of BCRP. The effect of vatalanib on ATPase activity of BCRP was determined using crude membranes pre-pared from HEK293/ABCG2 cells. Results Vata-lanib at the nontoxic dose ( 5 μmol · L-1 ) potentially reversed BCRP-mediated MDR in cancer cells, howev-er it had no effect on P-gp or MRP1 mediated MDR. Vatalanib did not alter the intracellular accumulation of MX in HEK 2 9 3 / ABCG 2 , and had no influence on the
BCRP-mediated drug efflux. The ATPase assay indica-ted that vatalanib may serve as a substrate of BCRP. Furthermore, vatalanib dramatically suppressed levels of both the protein and mRNA expression of BCRP in concentration-and time-dependent manners. However, reversal concentration of vatalanib had no influence on the total and phosphorylated forms of AKT and ERK1/
2 in resistant cancer cells. Conclusion Vatalanib could significantly reverse BCRP-mediated MDR with specificity, and its mechanism may correlate with the down-regulation levels of BCRP both mRNA and pro-tein in resistant cancer cells.
