Objective To determine the efficacy and safety of intravenous iron sucrose and oral iron dextran in renal anemia patients. Methods Sixty renal anemia patients were randomized into two groups:intravenous iron group(IV group, 100 mg iron sucrose twice a week) and oral iron group(oral group, 150 mg iron dextran every day). The changes in hemoglobin (Hb),hematocrit (Hct),serum ferritin (SF),and transferrin saturation (TSAT) were assessed on week 4,8, and 12 after treatment. The maintenance dosages of erythropoietin (EPO) after reaching treatment target and the adverse events were also observed. Results Hb increased after treatment in IV group [(79.87 ± 13.19) g/L to (106.11 ± 12.38) g/L] and oral group [(85.41 ± 11.49) g/L to (94.68 ± 10.06) g/L],and compared with that before treatment, there was significant difference in each group(P< 0.01 ). Also significant difference showed in Hb levels after treatment between two groups(P< 0.01 ). SF and TSAT levels were higher after treatment in IV group than those in oral group (P < 0.01 ). The adverse event was lower in IV group (0) than that in oral group (16.7%,5/30).Conclusions Oral iron dextran which has more adverse events and poor efficacy in curing anemia, can not correct anemia ideally. Meanwhile intravenous iron sucrose has positive effects on renal anemia with low adverse events, and it can be used as a long term iron supplementation in hemodialysis patients.

Objective To study the correlation between the red cell distribution width (RDW) ,cystatin C (Cys c) and lipopro‐tein (a) [LP (a)]with the lesion severity of coronary heart disease .Methods 130 cases of coronary heart disease(CHD) definitely diagnosed by coronary arteriography in the cardiology department of our hospital from March 2012 to September 2014 were select‐ed .The subjects were divided into the single‐vessel lesion group ,double‐vessel lesion group and multiple‐vessel lesion group accord‐ing to the coronary arteriographic results;furthermore the subjects were divided into the 1-30 points group ,31 -60 points group and the >60 points group according to the Gensini scores ;other contemporaneous 45 individuals of normal coronary arteriography were selected as the control group .RDW ,Cys C and LP (a) levels were detected in each group and the detection results were per‐formed the comparative analysis .Results The RDW ,CysC and LP (a) levels in the CHD group were significantly higher than those in the control group ,the differences were statistically significant (P< 0 .05) .With the increase of coronary lesion vessels number and Gensini score ,the RDW ,CysC and LP (a) levels showed roughly increasing trend ,the correlation analysis showed that the RDW ,CysC and LP (a) were positively correlated with Gensini scores .Conclusion The RDW ,CysC and LP (a) levels in the patients with CHD are higher than those in the normal control group ,which are closely related with the lesion severity of CHD and may be the new predictors of coronary lesion severity .

Small hairpin RNA (shRNA) was used to silence the HIF1alpha gene in human retinal pigment epithelial cells (RPE) under hypoxia in order to observe the effect of gene silencing on the expression of matrix metalloproteinase tissue inhibitor 1 (TIMP1). By using chemical hypoxic inducer CoCl2, to mimic RPE hypoxic environment, shRNA against the targeting region of HIF1alpha mRNA sequence was synthesized by a method of in vitro transcription, and the HIF1alpha was interfered in RPE cultured under hypoxia (induced by 150 micromol/L CoCl2). RT-PCR was employed to detect the expression of HIF1alpha and TIMP1. The expression levels of HIF1alpha and TIMP1 were measured by using Western blotting. The results showed that after the RPE were transfected with specific shRNA against HIF1alpha mRNA, RT-PCR revealed that under hypoxia, the efficacy of HIF1alpha gene silencing in RPE was 83.4%. Western blotting revealed that the expression levels of HIF1alpha protein was dramatically dropped. In addition. RT-PCR results demonstrated that the expression of TIMP1 mRNA was decreased by 28.9%, and the expression levels of TIMP1 protein were also significantly reduced by Western blotting. It was suggested that shRNA targeted against HIF1alpha mRNA could effectively silence the HIF1alpha gene, subsequently effectively inhibit the hypoxia-induced up-regulation of TIMP1.
