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.

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 24h urine protein (r=-0.754, P<0.05), between IL-13 and 24h 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 Our purpose was to improve the konwlege and diagnosis level of esophageal intramural pseudodiverticulosis(EIPD).Methods All 3 cases were underwent single and double contrast esophagograms.Analyze the findings on esophagography in 3 cases.Results Multiple small tiny cyst like outpouchings with a narrow neck extending outward esophageal wall were found in all of the 3 cases, the length range of outpouchings diameter was 1-4 mm,and the length range of neck was 1-2 mm,the pseudodiverticula had a diffuse distribution in 2 cases,and segmental distribution on the middle and the lower esophagus in the other case.Some necks of pseudodiverticula incline to stomach with 30?-45? in 2 cases;and intramural tracking was found in 1 case,the length range of tracking was 5-10 mm;esophageal stenosis in esophagogastic junction and reflux esophagitis was found only in 1 case;1 case underwent endoscopy and ostiums of pseudodiverticula were found;biopsy showed submucosal chronic inflammation surrounding the neck of pseudodiverticula,squamous metaplasia of the epithelium in both the neck and outpouchings.Conclusion EIPD is a rare benign disorder characterized by dilation of the submucosal glands.The value of esophagography is to distinguish sublimes ulcer caused by esophagitis and esophageal fenestrate from EIPD.The characteristic radiographic appearance is numerous intramural esophageal contrast-filled cystiform outpouchings,and some necks incline in the direction of stomach.When the typical appearance found on barium studies,the diagnosis of EIPD can be made.

Objective To investigate the possible protective effect of Shenqingyin Decoction on the kidney of experimental diabetic rats and its possible mechanism. Methods Totally 40 rats with diabetes induced by streptozocin were divided into 4 groups: diabetes model group, Shenqingyin group, Benopril group and Shenqingyin-Benopril combination group. After 8 weeks' treatment, blood glucose, renal function and 24h urine protein were measured, and malondialdehyde (MDA) in renal tissues and urine, superoxide diamutase (SOD) activity and serum transformed growth factor-β_1(TGF-β_1) were tested; renal pathological changes were observed with light microscope as well. Results The serum BUN, Scre of all medicine groups were significantly improved, which did not significantly differ from that in control group (P>0.05). However, it had no obvious improving effect on blood sugar. The content of 24h urine protein in all medicine groups was significantly lower than that in model group (P<0.05 or P<0.01), and Shenqingyin-Benopril combination group had the significantly lower level than the other two medicine groups (P<0.01). MDA in renal tissues and urine, SOD activity and serum TGF-β1 in all medicine groups significantly differed from those in the model group (P<0.05 or P<0.01), and Shenqingyin-Benopril combination group had obvious difference with the other two medicine groups (P<0.01). Light microscopy showed amelioration of different degree in renal pathological changes, but with no significant differences in all medicine groups. Conclusion Shenqingyin Decoction has a protective effect on the kidney of experimental diabetic rats, and it has some synergetic effect when combined with Benopril. The mechanism may be related to inhibiting oxidative stress, improving the body's antioxidant ability and decreasing the expression of inflammatory factor TGF-β_1.
