Objective To determine bone mineral density (BMD) and biochemical parameters of bone metabolism in premenopausal female patients with systemic lupus erythematosus(SLE), and investigate the correlation between them. Methods Lumbar and femoral BMD in 30 female patients with SLE was determined by dual energy X ray absorptiometry. In 30 female patients and 39 controls, the corrected serum levels of calcium, phosphorus, alkaline phosphatase, creatinine and albumin were measured by routine methods, and bone specific isoform of alkaline phophatase, propeptide of type 1 procollagen, deoxypyridinoline excretion, telopeptide of type 1 collagen, osteocalcin, parathyroid hormone, 25-OH vitamin D, testosterone, progesterone, estradiol, follicle stimulating hormone and luteinotropic hormone were measured by ELISA or RIA. Results According to the WHO criteria, 39% patients with SLE had normal BMD, 46% had osteopenia and 15% had osteoporosis at the lumbar spine; at the femoral neck 38.5% had normal BMD, 38.5% had osteopenia and 23% suffered form osteoporosis. All other bone resorption and formation markers measured were not significantly different except significantly higher corrected serum levels of albumin calcium (P=0.0001)and significantly lower osteocalcin level and phosphorus value(P=0.03,P=0.002) were found in the SLE patients. Of all sex hormones tested lower testosterone and higher follicle stimulating hormone concentration were seen in patients with SLE(P=0.001,P=0.42). Conclusion A high incidence of osteopenia and osteoporosis was found in premenopausal patients with SLE, which seems to be attributable, at least in part , to decreased bone formation in SLE patients.

BACKGROUND:Vascular endothelial growth factor(VEGF)can promote vascular endothelial regeneration,inhibit thrombosis,and attenuate neonatal intimal thickness and luminal stenosis degree.OBJECTIVE:The present study established atherosclerosis models in rabbits and observed the effects of local transfection of VEGF gene on restenosis after angioplasty.DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the Laboratory of Microorganism,Tongji Medical College,Huazhong University of Science and Technology between November 2004 and December 2006.MATERIALS:Rabbits were daily raised with high-fat diet to create atherosclerosis models.Twenty successful rabbit models were randomly and evenly divided into a control group and a gene treatment group.METHODS:The DcNDA 3.0 recombinant human VEGF165(hVEGF 165)was trimsferred to the ventral aorta through the use of Foley's catheters.and the pcDNA3.0 was transfefred in the controls.MAIN OUTCOME MEASURES:At 1,2,and 4 weeks after surgery,luminal area of left renal artery opening was measured by MRI.At 2 and 4 weeks after surgery,the ratio for intimal to medial area was obtained through the use of HMIAS-2000 high definition color medical image analysis software.Simultaneously,vascular endothelial cell regeneration was observed by immunohistochemistry of factor Ⅷ related antigen.RESULTS:The pcDNA3.0/hVEGF 165 could be successfully transferred through the use of Foley's catheters.At 2 and 4 weeks after surgery,luminal area was larger in the gene treatment group than in the control group(P<0.01);simultaneously, the ratio of intimal to medial area was significantly smaller in the gene treatment group than in the control group(P<0.05).In the gene treatment group,expanded vascular endothelial cell regeneration was accomplished at 2 weeks after surgery,while in the control group,it took 4 weeks.CONCLUSION:pcDNA3.0/hVEGF 165 gene transduction can promote local vascular endotllelialization and apparently attenuate restenosis degree and intiaml thickening.

Exons encoding the variable regions of the light and heavy chain of the murine McAb HIT3a against CD3 antigen were isolated from HIT3a gene library and inserted into mammalian expression vectors containing the human K and y1 region exons. The chimeric genes were transfected into murine SP2/0 hybridoma cells by Lipofectin. Antibody levels of culture supernatants from transfectomas ranged 21~32 ?g/ml. The chimeric antibodies bound specifically to human T cells and competed effectivelly with the parental anti-CD3 murine McAb for binding to CD3 antigen on human T cells. The ability to promote antibody-dependent cell-mediated cytolysis was significantly enhanced with the chimeric antibodies as compared with anti-CD3 murine McAb. The mitogenic activity of human T cells can be suppressed and enhanced by the anti-CD3 chimeric antibodies. The cytotoxicity to tumor cells and proliferation of human T cells mediated by the anti-CD3 chimeric antibodies were much higher than IL-2 alone. Chimeric HIT3a antibody is a clinically relevant, genetically engineering antibody with potential use in treatment of graft-versus-host disease in tranplantation, autoimmune diseases and some tumors.
