BackgroundMonocyte chemotactic protein-1 (MCP-1)plays an important role in the tumor,inflammation,diabetic retinopathy and other neovascular disease,but the expression and the role of MCP-1 in the oxygen induced retinopathy(OIR) model have rarely been reported. Objective This study was to investigate the expression of MCP-1 in the retina development of newborn mouse and in mouse models with OIR.Methods C57BL/6J newborn mice were divided into two groups and 60 mice in each group.Mice in OIR group were exposed to 75％ oxygen for 5 days and then to room air.All mice in normal control group exposed to room air only.Ten mice in each group were randomly chosen and sacrificed at postnatal 5,7,12,14,17,21 days.The expression of MCP-1 in mouse retina was detected with the method of immunohistoehemistry and reverse transcription polymerase chain reaction(RT-PCR).Results MCP-1 positive cells were seen in normal mouse retina.Up-regulation of MCP-1 positive cells was detected both in 12 days in normal control group and in 14 days in OIR group.MCP-1 mRNA was detected in mouse retina at 5 days,and a transient up-regulation of MCP-1 mRNA was observed in 12 days in normal control group.MCP-1 mRNA in OIR group significantly increased in 14 days in comparison with the normal control group( P =0.028,P =0.001 ). Conclusions Expression of MCP-1 is detectable in whole retinal development procession of mice.A transient up-regulation of MCP-1 expression is detected in the critical period of retinal vascular development in mice models with OIR,which is closely related to the retinal vascular development and progression of retinal new vessels.

Diabetic vascular complications are the key cause of the poor life quality and high mortality in diabetic patient. Advanced glycation end products (AGEs) and its cross-links play important roles in the diabetic vascular complications. Endothelial cells damage induced by AGEs may account for the initial agent for diabetic vascular complications. Recent studies have shown that AGEs inhibitors and breakers can prevent and reverse these complications. This article reviewed the research progress of AGEs and endothelium dysfunction. The potential therapeutic method was also stated.

Objective To investigate the sensitivity of BIOMED-2 primer system in adult acute lymphoblastic leukemia (AIJ,) patients Ig gene rearrangement, and to analyze their frequency, corearrangement pattern, utilization of V, D and J genes and composition of junctional regions. Methods Amplification of rearranged IgH (complete and incomplete), IgK, IgK-Kde and IgL was performed in standard PCR in 29 adult ALL patients. Monoclonal PCR products were subjected directly to DNA sequencing. Sequences were identified by comparison with all known human Ig germline sequences to analyze the recombination patterns, somatic mutations and germline gene segments usage. Results IgH, incomplete IgH, IgK, igK-Kde and Igl, rearrangements were found with positive rate of 70.8%, 12.5% , 29.2% , 25.0% and 0 of B-ALL patients, respectively. All B-ALL patients displayed at least one pattern of Ig gene rearrangements. In TALL, one of five patients was found with incomplete IgH rearrangement, two patients were found with IgK rearrangements and two patients were PCR-negative. The sequence analysis showed that the most frequently used V, D, J segments in adult B-ALL patients were from VH3/VH4 families, DH3 family and JH6 family, respectively. Four of five IgK rearrangement used VκI family. 23.5% B-ALL IgH contained scattered replacement mutations with replacement to silent substitution ratio < 1 in complementarity determining regions. Conclusion BIOMED-2 multiplex PCR analysis strategy is a reliable and useful technique in the adult BALL patients.

Objective To study the quantification of MDR1 and WT1 gene expression in patients with de novo acute myeloid leukemia(AML)and to explore the role of these two genes in clinical drug resistance and their correlation with risk stratification. Methods A real time quantitative reverse transcriptase polymerase chain reaction method was established for detecting MDR1 and WT1 gene expression levels in 63 de novo AML patients.Resuits The expression of WT1 and MDR1 was significantly higher in de novo AML patients than in normal controls (P＜0.001).WT1 levels were significantly correlated with corresponding levels of MDR1 gene in de novo AML patients(P=0.004).Expression levels of WT1 and MDR1 gene were not associated with FAB subtype and risk stratication(P＞0.05).AML patients with FLT3-ITD mutations had a significantly higher WT1 expression level as compared to with those without(P＜0.05),on the contrary MDR1 expression was not associated with FLT3-ITD mutations(P＞0.05).Patients with co-expression of high levels of WT1 and MDR1 had a significantly lower complete remission rate after induction therapy than those with low levels(P＜0.05).Conclusion There is a positive correlation between MDR1 gene expression and WT1 gene expression in AML.Quantification of the two gene expression together is more effective for judgement of prognosis in AML.
