Objective To explore the feasibility of clinical application of biodegradable polymer-coated drug-eluting stent. Methods Thirty each of the drug-eluting stent or bare-metal stents were implanted randomly into the anterior descending arteries, circumflex and right canine coronary arteries of thirty healthy pigs. The pathological examination was taken at 2 weeks to 6 months after coronary angiography to investigate the inflammation, thrombosis and endothelialization. Results Macroscopic observation of the stented arteries demonstrated complete incorporation of stent wires into the arterial wall and smooth vessel lumens. There were no significant differences existing between two kinds of the stents in terms of thrombosis, inflammation and endothelialization. The lumen loss in the biodegradable polymer-coated drug-eluting stent group is less than that in the bare-metal stent group. Conclusion The biodegradable polymer-coated drug-eluting stent is promising with good biocom-patibility, blood compatibility and phyaicochemical stability after being implanted into pig coronary arteries. The blood vessel transplanted with the drug-eluting stents maintains a high patency rate due to rapid endothelialization.

Objective To study the effects of cytokines Th1 and Th2 in Class V lupus nephritis (V-LN). Methods Serum concentration of Th1 cytokines (IFN-γ, IL-1, IL-2 and TNF-α) and Th2 cytokines (IL-4, IL-5, IL-6, IL-10 and IL-13) were simultaneously analyzed using fast quant human Th1/Th2 protein array, and Pearson analysis was used to evaluate the association between cytokines and clinical parameters. Results ① Cytokine profiling: Among the 9 cytokines detected simultaneously by fast quant human Th1/Th2 protein array, the expression of four cytokines was up-regulated obviously, namely, Th1 cytokines (IL-2) and Th2 cytokines (IL-4, IL-10 and IL-13); that of IL-10 was 10 times above the normal control. ② Pearson correlation analysis: There was a positive correlation between IL-10 and SLEDAI (r=0.877, P<0.01), but a negative correlation between IL-10 and hemoglobin concentration (r=-0.856, P<0.01). There was also a negative correlation between IL-4 and 24h urine protein (r=-0.754, P<0.05), between IL-13 and 24h urine protein (r=-0.769, P<0.05). Besides, IL-1 and creatinine were positively correlated (r=0.784, P<0.05). Conclusion There were extensively abnormal Th2 cytokines in V-LN patients, suggesting that anti-Th2 therapy may produce a marked effect on V-LN.

Objective To obtain a global view of cytokine profile in lupus nephritis (LN), and to co-mpare the pattern of cytokine profile in patients with different renal lesions, primarily diffuse proliferative lupus nephritis (Ⅳ-LN) and membranous lupus nephritis (Ⅴ-LN). Methods Thirtypatients with biopsy proven active LN (class Ⅳ, n=15; class Ⅴ, n=15) and 15 healthy controls were enrolled in this study. Serum conc-entration of Th1 cytokines (IFN-γ, IL-1, IL-2, and TNF-α) and Th2 cytokines (IL-4, IL-5, IL-6, IL-10, IL-13) were simultaneously analyzed using Fast Quant Human Th1/Th2 protein array. Results ① Cytokine profiling: in patients with class Ⅳ-LN, the levels of most of the detected cytokines elevated marked compared to normal controls, including both Th1 (IL-2, INF-γ and TNF-α) and Th2 (IL-4, IL-6, IL-10 and IL-13) cytokines. Among them, both Th1 (INF-γ and TNF-α) and Th2 (IL-6, IL-10 and IL-13) cytokines were 10 times higher than normal controls. However, patients with class Ⅴ LN demonstrated a different cytokine pro-filing compared to class Ⅳ LN. Only 4 out of 9 cytokines were significantly increased. In addition to IL-2, all of those cytokines produced by Th2 (IL-4, IL-10 and IL-13) as well as IL-10 was 10 times higher than normal controls. The main difference of cytokines between patients with class Ⅳ LN and patients with class Ⅴ LN was among Th1 cytokines (IFN-γ, IL-2 and TNF-α). There was a significant correlation between clinical manifestations and cytokines in class Ⅳ LN, especially among Th2 cytokine. There was positive correlation between IL-5 and anti-dsDNA titer(r=0.708, P<0.05), IL-5 and creatinin(r=0.681, P<0.05) and IL-10 and SLEDAI scores (r=0.877, P<0.0 ). On the other hand, there was also negative correlation between some Th2 cytokines and clinical manifestations. There was negative correlation between IL-5 and complement C3 level (r=-0.643, P<0.05), IL-10 and proteinuria(r=-0.659, P<0.O5), IL-10 and hemoglobin level (r=-0.856, P<0.001), as well as IL-13 and proteinuria (r=-0.769, P<0.05). In addition, IL-1 was positive correlated with SLEDAI, while it was negatively correlated with bemoglobulin level. As for class Ⅴ LN, there was positive correlation between IL-1 and creatinin level (r=0.784, P<0.05), but negative correlation between IL-4 and proteinuria (r=-0.754, P<0.05). Conclusion Patients with class Ⅳ renal lesion have shown a broad changes of cytokine activity, while up-regulation of Th2 cytokines is more predominant in patients with class Ⅴ LN. These suggest that the expression of different cytokines may be associated with different patterns of lupus renal lesions. These findings may shed light on the further exploring of the underlying mechanisms that mediate different patterns of renal lesions, as well as designing a rational therapeutic strategy for the treatment of LN.
