Objective To investigate the effects and adverse reactions of high-dose glucocorticoid on early active rheumatoid arthritis patients.Methods The early active rheumatoid arthritis patients were randomly divided into three groups:high dose group (16 patients,with large doses of glucocorticoid therapy),low dose group (17 patients,with small doses of glucocorticoid therapy),and control group (41 patients,with no glucocorticoid therapy).Compared the differences among the three groups.Results The changes in the three groups were different in joint pain,joint swelling,morning stiffness,erythrocyte sedimentation rate,rheumatoid factor and C-reactive protein (P ＜ 0.05).The high dose group was significantly better than the other two groups in the above variables alleviating,in the 1 week after the treatment.The changes in the three groups had no significant difference of bone mineral density,Larsen hip score (P＞ 0.05).The NSAIDs days in the control group was significantly longer than the high dose group,low dose group [(51.17 ± 2.56) d vs.(14.16 ± 0.71) d,(26.50 ± 1.59) d],the difference was statistically significant (P ＜ 0.05).Rate of weight gain in the high dose group,low dose group was significantly higher than the control group [5/16,4/17 vs.4.9％ (2/41)],the difference was statistically significant (P ＜ 0.05).Body weight increased in the high dose group and low dose group occurred mainly in the following 1.5 months of therapy,with the discontinuation of cortices-teroids,weight gradually fell to normal.Gastrointestinal discomfort incidence in the control group was significandy higher than that in the high dose group,low dose group [51.2％ (21/41) vs.2/16,3/17],the difference was statistically significant (P＜ 0.05).Conclusions High-dose glucocorticoid can rapidly relieve clinical symptoms and inflammation in early active rheumatoid arthritis patients.High-dose corticosteroids do not bring too many side effects to patients but weight gain,and it reduces the patients' gastrointestinal discomfort greatly,because of the decrease use of NSAIDs.

The clinical treatment of large-area trauma or intractable wound is very difficult. Finding a suitable wound dressing is very important for wound healing. Stem cells can secrete and express a variety of cytokines necessary for wound healing, and can grow and proliferate for a long time in three-dimensional (3D) scaffold materials to maintain their proper structure and function. A large number of studies have shown that transplanting stem cells-3D scaffold complex into the skin wound in the form of a moist dressing can significantly improve the efficiency of stem cells transplantation, shorten the wound healing time, and reduce scar formation. Stem cells-scaffold complex are likely to be a good wound dressing. This article mainly summarizes the selection of wound dressing and the research status of stem cells-3D scaffold complex as a wound dressing, aiming to provide a theoretical basis for the clinical application of stem cells-3D scaffold complex.

Objective To investigate the effect of propofol on expression of cyclinD1 and apoptosis in spinal cord neurons induced by ischemia-reperfusion (I/R) .Methods Sixty male Wistar rats weighing 200-250 g were randomly divided into 2 groups ( n = 30 each): group A I/R and group B propofol + I/R. The animals were anesthetized with 7% chloral hydrate 6 ml?kg-1. The abdomen was opened and the abdominal aorta was clamped distal to the left renal artery for 20 min. The aortic cross clamp was then released to allow reperfusion. In propofol group propofol 100 mg?kg-1 was administered intraperitoneally (IP) during the operation. Neurologic function was assessed using Taylor scale (0 = unable to move hind limbs, 4 = normal function) at 6 h after operation and on postoperative day 1, 2, 3, 7 (n = 6 at each time point) . The animals were killed after neurologic function evaluation and the spinal cord was removed for microscopic examination, detection of apoptosis in the spinal cord neurons ( TUNEL) and determination of cyclinD1 expression (immuno-histochemistry) . Results The histo-pathological damage to the neurons was significantly lighter, the neurological function better and the apoptotic index and the cyclinD1 expression were significantly lower in propofol group than in I/R group. Conclusion Propofol protects spinal cord against I/R injury by reducing neuronal apoptosis through down-regulation of cyclinD1 expression.
