Objective:To discuss the efficacy of early rehabilitation nursing for arthrogryposis and shoulder-hand syndrome in stroke patients.Methods: 100 cases of stroke patients were divided into intervention group and control group(each group 50). Patients in the control group received the regular nursing for stroke, while psychological nursing, continuous passive motion, and proper position were implemented in addition in the the intervention group. Fugl-Meyer assessment (FMA), activities of daily living (ADL) were used to evaluate the functional movement of the hand (seven items with a total score of 14) after 6 weeks. The modified Ashworth scale (MAS) and the modified rankin scale (MRS) were also observed based on symptom scoring. Results: The intervention group had significant difference in limb spasmand pain of shoulder joint compared with the control group(t=11.200,t=12.651;P<0.05). And early rehabilitation nursing was able to improve the locomotive function and daily life ability of the patients.Conclusion: Early rehabilitation nursing for arthrogryposis and shoulder-hand syndrome play a vital role in improving the living quality of stroke patients and making then return to the society.

Objective To investigate the effect of 1,25(OH)2D3 on high glucose induced podocyte injury and its signal transduction mechanism.Methods Differentiated mouse podocytes were exposed to normal glucose,high glucose,and different concentrations of 1,25(OH)2D3 or LY294002 (a selective PI3K inhibitor) for 24 h.PCR and immunofluorescent staining were used to detect nephrin,podocin,and desmin.Western blotting was used to detect protein expression of nephrin,podocin,desmin,PI3K,Akt and p-Akt.Results Compared with high glucose group,1,25(OH)2D3 (100 nmol/L and 1000 nmol/L) significantly up-regulated the expression of podocin and nephrin in podocytes induced by high glucose (P ＜ 0.05).Meanwhile,1,25(OH)2D3 (100 nmol/L) significantly reduced the expression of desmin (P ＜ 0.05).PI3K and p-Akt were obviously reduced in high glucose group.In the presence of 1,25(OH)2D3,the trends were reversed.However the above effects of 1,25(OH)2D3 were abolished when p-Akt was blocked by the PI3K inhibitor LY294002.Conclusions 1,25 (OH)2D3 can inhibit high glucose-induced pedocyte injury through PI3K/p-Akt signaling pathway.

BACKGROUND: Macrophage migration inhibitory factor (MIF) is mainly concerned with macrophage mobilizing function, as the upper stream cytokine of tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), which may have critical effect in the process of the onset of rheumatoid arthritis. OBJECTIVE: To explore the correlations between the change of serum MIF and the activity of rheumatoid arthritis (RA) disease.DESIGN, TIME AND SETTING: Non-randomized control and case study, which was carried out in the Bethune International Peace Hospital of Chinese PLA from September in 2005 to October in 2006.PARTICIPANTS: Sixty RA patients were included in this study, and other thirty healthy subjects were selected as the control group. There were significant differences in age and sex between the two groups. METHODS: Clinical data of sixty RA patients were selected by carrying out retrospective analysis, then on the basis of disease activity score (DAS) accumulated points, they were divided into active and inactive group respectively, who were contrasted with 30 health adults. MAIN OUTCOME MEASURES: ① Morning stiffness (in minutes), joint tenderness index, arthrocele index, semi-quantity rheumatoid factor (RF), C-reactive protein concentration (CRP), erythrocyte sedimentation rate (ESR), and platelet count (PLT) were recorded; ② To compare the level of serum MIF, IL-1β and TNF-α among active group, inactive group, and control group; ③ The correlation analysis was carried out among the level of serum MIF, inflammatory index and clinical observation index.RESULTS: There was significantly increased in serum MIF of patients in the active group compared to of inactive and normal groups (P < 0.05), but there were no significantly differences between inactive and control groups (P > 0.05). There were significant correlations between the serum MIF concentration and active inflammatory index of RA disease, blood sedimentationrate (ESR), C-reactive protein (CRP), platelet counting (PLT), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), swell joint index (SJI) and tenderness joint, but no significant difference was observed between the serum MIF, age, disease course, morning stiffness and rheumatoid factor (RF).CONCLUSION: The serum MIF concentration is significantly increased in patients with RA, and it may be a useful parameter for monitoring disease activity of RA.
