Objective To investigate the changes of disease activity and clinical significance in the course of treatment in patients with SLE.Method 286 cases of SLE were reviewed and compared the changes of SLEDAI scores in different disease duration.Results The SLEDAI scores of patients whose first treatment courses less than 1 month and 1 to 3 months were significantly lower than those patients whose were 4 to 6 months and more than 6 months. After treatment for 2 months to 3 years, the SLEDAI scores were not correlated with cumulated dosage of corticosteroids.Conclusions For the patients of short first treatment course, the treatment could relieve SLE disease activity rapidly and effectively to some extent; while for the patients whose first treatment courses were relatively long ,the relif of disease activity was relatively slow. After treatment for 2 to 3 months, the disease of SLE patients was more active than other periods, and it was inclined to produce visceral damage. As mentioned above ,we should pay attention to this phenomenon.

PurposeHeroin addiction is a chronic and recurrent functional brain disease, there are some functional changes in specific brain regions, but the network character remains unclear. The aim of this paper is to explore the network character of brain resting-state functional network in heroin addicts, to identify the potential neuromechanism of heroin addiction from the perspective of brain network.Materials and Methods Thirty heroin addicts (HA group) and twenty-nine healthy controls (control group) underwent resting-state functional MRI scanning using GE 3.0T MRI scanner. The brain functional networks were constructed based on graph theory, the small-world properties and node properties were calculated and compared between the two groups, the correlation between the total dosage of heroin and node degree was analyzed.Results Compared with control group, the small world characteristics of HA group was altered with statistically significant difference (P<0.05, corrected by false discovery rate); the node degrees in orbit frontal regions increased, while those in occipital brain regions decreased (P<0.05, corrected by false discovery rate). No correlation was found in HA group between node degree and the total dosage of heroin.Conclusion These results suggest that topology of functional brain networks were altered in heroin addicts which tends to random networks; increased motivational driving to the salience of drug and decreased visuospatial attention in heroin addicts may provide a strategy for identifying the neuromechanism of heroin addiction.

OBJECTIVE:To study the anti-oxidative effects of spirulina kinase (SPK) in vitro. METHODS:The methods of phenanthroine-Fe2+ oxidation method,DPPH and auto-oxidation of pyrogallol were used to measure the effects of different concen-trations of SPK on scavenging hydroxyl (OH-) free radical,DPPH free radical and superoxide anion (O2-) free radical;IC50 of SPK was calculated. Prussian blue reaction was used to determine total reducing ability(by absorbance)of different concentrations of SPK to Fe3+. Vitamin C(VC)was used as positive control in above trials. RESULTS:SPK could eliminate the OH-free radical, DPPH free radical and O2- free radical in concentration-dependant manner,and the maximum elimination rate of SPK to OH- free radical and DPPH free radical were 86.82% and 78.98%(IC50 were 54.31,0.636 g/L),which were higher than VC (64.77%, 73.49%). The maximum elimination rate of SPK to O2- free radical was 78.31%(IC50 was 3.918 g/L),which was lower than VC (94.14%). In reducing ability test,SPK improved absorbance in reducing ability test system,and maximum absorbance was simi-lar to VC in concentration-dependant manner. CONCLUSIONS:SPK has obvious anti-oxidant activities in vitro.
