Objective To evaluate the effect and side-effect in patients with multiple myeloma by the treatment of T-VAD.Methods To observe the effect and side-effect in 23 newly diagnosed patients with the treatment of T-VAD,and analyze them.Results Out of 23 patients,9(39%)patients gained complete remission(CR)and 11(49%)achieved partial remission(PR).The median survival time was 46 months.The side-effects consisted of fatigue(100%),somnolence(78%),constipation(69%),infection(48%),secondary diabetes mellitus(30%),numbness(17%),leukopenia(22%)and no one patient experienced deep vein thrombosis(DVT).Disease free survival of three years was 50%.Conclusion The treatment 0f T-VAD on patients with MM is an effective regimen,though there are many side-effcts,such as infection,they are relatively well-tolerated.

BACKGROUND:There are many postmenopausal women taking hormone, which leads to much loss of bone mass, further inducing fragility fractures. The studies on the hormone exposure combined with ovariectomy-induced osteoporotic model are still immature, and the related molecular mechanism remains unclear. OBJECTIVE: To establish the rat osteoporotic model induced by ovariectomy combined with glucocorticoid exposure and to explore the underlying molecular mechanism. METHODS: Thirty 3-month-old female Sprague-Dawley rats were randomly divided into blank control, sham and model groups (n=10 per group). The rats in the blank control group received no intervention; rats in the sham group were clipped off a little of coeliac adipose tissue; the model rats received bilateral ovariectomy and 4-week administration of glucocorticoid. RESULTS AND CONCLUSION:At 4 weeks after modeling, compared with blank control and sham groups, the model group showed significantly lower bone mineral density of the femur, number of bone trabeculae and bone volume/total volume, and significantly wider bone trabecular spacing. Additionally, the model group revealed the damaged bone trabecular structure and thiner cortical bone. The expression level of Runx2 was downregulated whereas both collagen type 1α1 and peroxisome proliferators activated receptor γ mRNA were upregulated in the model group. These findings suggest that ovariectomized rats exposed to glucocorticoid rapidly develop femur osteoporosis, maybe by downregulating the expression of Runx2, as well as upregualting collagen type 1α1 and peroxisome proliferators activatedreceptor γ mRNA.
