The levels of IL - 23,IL - 17 in united intervention group were lower than those in respective intervention groups(P ﹤ 0. 05),and the levels in Prednisone intervention group were lower than those in Azithromycin intervention group(P ﹤ 0. 05). Conclusions IL - 23 / IL - 17 axis' high activity may be one of the immunologic mechanisms of Adriamycin - induced nephrosis. Azithromycin may inhibit the high activity of IL - 23 / IL - 17 axis to relieve the Adriamycin - induced nephrosis. The inhibition on IL - 23 / IL - 17 axis of Azithro-mycin was similar to Prednisone,and Azithromycin may enhance the effectiveness of Prednisone.

AlM: To compare the anterior segment measurements derived from optical low coherence reflectometer ( Lenstar LS900 ) and combined Scheimpflug - Placido disk topographer ( Sirius) .
METHODS: ln this study, we enrolled healthy myopic subjects 54 ( 87 eyes ) . The central corneal thickness (CCT), anterior chamber depth (ACD), flat keratometry ( FK) readings , steep keratometry ( SK ) readings and white to white ( WTW ) were measured by LS900 and Sirius. Evaluation and analysis were performed using paired t tests, the Pearson correlation, and Bland-Altman analyses.
RESULTS: The CCT and ACD measurements were significantly lower whereas FK, SK and WTW measurements were higher with LS900 (P<0. 001). Mean differences were -6. 11 ± 6. 32μm,-0. 09 ± 0. 07mm, 0. 18 ± 0. 25D, 0. 21 ± 0. 36D and 0. 25 ± 0. 39mm with statistical significant (P<0. 01). Pearson correlation analysis showed high correlation between the 2 devices for all measurements (P<0. 001). On Bland-Altman analysis, 95% limits of agreement for all measurements were 6. 26 to -18. 49μm; 0. 04 to 0. 22mm; 0. 68 to 0. 32D; 0. 92 to 0. 50D and 1. 00 to 0. 5mm.
CONCLUSlON: Anterior segment parameters evaluated with LS900 and Sirius systemare correlated well and achieve good agreement. However, there are significantly statistical differences which may be caused by the different measurement modes, so they may not be interchangeable use under certain clinical circumstances.
9.Progress of berberine for treatment of type 2 diabetes.
China Journal of Chinese Materia Medica 2014;39(8):1374-1378
Berberine is the major component of Coptidis Rhizoma and it has been used as anti-infection, anti-inflammation drug for gastrointestinal diseases. In recent years, evidence showed that it could regulate glucose and lipid metabolism. Moreover, its activity had been tested by clinical trials and animal researches. The mechanisms of berberine in diabetes include: improving the function of beta-cell; prompting insulin secretion and islets regeneration, lowing lipid level, regulating glucose and lipid metabolic by influence transcriptional factors expression such as PPARgamma, C/EBPalpha, SREBP-1c, LXR, having the activities of anti-oxidation and inhibiting reductase to repress oxidative stress state and regulate metabolic signal pathway. Although numbers of data supported that berberine could improving insulin resistance by clinical trials and animal studies, the large scale, multicenter clinical trials are needed to evaluate the effects of berberine for diabetes and its complications in the time of evidence-based medicine.
