Its pathogenesis and the treatment mechanism of glucocorticoid have not been fully elucidated. The aim of this study was to determine the relationship between p300 and the pathogenesis, glucocorticoid therapy in mice with HSPN, respectively. Methods: Forty-eight C57BL/6N male mice, weighing 18 to 20 g, were selected (3–4 weeks old, n = 8 per group). The mice in the normal control group (Group I) were given normal solvent and the HSPN model group (Group II) were given sensitizing drugs. The mice in Group III were injected intraperitoneally with dexamethasone after being given sensitizing drugs. Meanwhile, mice in Groups IV, V and VI with conditional knockout of p300 were also given normal solvent, sensitizing drugs and dexamethasone. The levels of serum IgA, creatinine, and circulating immune complex (CIC) concentrations, 24 h urinary protein and urinary erythrocyte in C57 wild mice, and p300 conditional knockout mice in each group were measured. The expression of p300 in renal tissues and the expression of glucocorticoid receptor (GR)α and β, transforming growth factor (TGF)-β1, and activator protein (AP)-1 after dexamethasone treatment were determined by real-time polymerase chain reaction and Western blotting. Results: Compared with the normal solvent control group (Group I), the expression of p300 mRNA in the model group (Group II) was significantly up-regulated. Western blotting further confirmed the result. Urinary erythrocyte count, 24 h urinary protein quantification, serum IgA, CIC, and renal pathologic score in Group V were distinctly decreased compared with non-knockout mice in Group II (9.7 ± 3.8 per high-power field [/HP] vs. 18.7 ± 6.2/HP, t = 1.828, P = 0.043;0.18 ± 0.06 g/24 h vs. 0.36 ± 0.08 g/24 h, t = 1.837, P = 0.042;18.78 ± 0.85 mg/mL vs. 38.46 ± 0.46 mg/mL, t = 1.925, P = 0.038;0.80 ± 0.27 μg/mL vs. 1.64 ± 0.47 μg/mL, t = 1.892, P = 0.041;7.0 ± 0.5 vs. 18.0 ± 0.5, t = 1.908, P = 0.039). Compared with non-knockout mice (Group III), the level of urinary erythrocyte count and serum IgA in knockout mice (Group VI) increased significantly after treatment with dexamethasone (3.7 ± 0.6/HP vs. 9.2 ± 3.5/HP, t = 2.186, P = 0.024;12.38 ± 0.26 mg/mL vs. 27.85 ± 0.65 mg/mL, t = 1.852, P = 0.041). The expression level of GRα was considerably increased in the knockout group after dexamethasone treatment compared with non-knockout mice in mRNA and protein level (t = 2.085, P = 0.026;t = 1.928, P = 0.035), but there was no statistically significant difference in the expression level of GRβ between condition knockout and non-knockout mice (t = 0.059, P = 0.087;t = 0.038, P = 1.12). Furthermore, the expression levels of glucocorticoid resistance genes (AP-1 and TGF-β1) were notably increased after p300 knockout compared with non-knockout mice in mRNA and protein level (TGF-β1: t = 1.945, P = 0.034;t = 1.902, P = 0.039;AP-1: t = 1.914, P = 0.038;t = 1.802, P = 0.041). Conclusions: p300 plays a crucial role in the pathogenesis of HSPN. p300 can down-regulate the expression of resistance genes (AP-1 and TGF-β1) by binding with GRα to prevent further renal injury and glucocorticoid resistance. Therefore, p300 is a promising new target in glucocorticoid therapy in HSPN.展开更多

Renal pathological findings under light microscope, immunofluorescence and electronic microscope were analyzed and also compared between 31 children with IgA nephropathy and 32 biopsied children with HSPN. The results showed that the onset age was over 12 years in 25.8 % children with IgA nephropathy, but only 10 % in HSPN （P〈0.05）. The clinical patterns of IgA nephropathy and HSPN were similar, but extra-renal manifestations were more often in HSPN, all of them had skin purpura, 59 % had gastrointestinal symptoms and 47 % suffered from arthralgia, compared with only abdominal pain in 3.2 % children with IgA nephropathy. The renal pathological investigation showed global sclerosis in 35.5 % of IgA nephropathy and 3.1% of HSPN, mesangial sclerosis in 41.9 % of IgA nephropathy and 6.3 % of HSPN, but endothelial proliferation in 65.6 % of HSPN and 29 % of IgA nephropathy （all P〈0.01）. Thin basement membrane nephropathy was only found in 6. 5 % children with IgA nephropathy, no in HSPN. The electronic dense deposits in HSPN were sparse, lodse and wildly spread in glomerular mesangium, subendothelial area and even intra basement membrane, but it was dense, lumpy and mostly limited in mesangium and paramesangium in IgA nephropathy. Predominant IgA deposits were found in 81.2% of HSPN, and overwhelming IgG deposits in 12.5 % of HSPN with relatively weak IgA deposits, moreover 6.3 % of HSPN showed linear IgG deposits in glomerular capillary. Totally 71. 9 G of HSPN had IgG deposits in glomeruli and only 19.4% of IgA nephropathy showed glomerular IgG deposits （P〈0. 01）. No IgG deposit was observed in 81. 6 % of IgA nephropathy, among them most showed IgA and IgM and/or C3 deposits, moreover overwhelming IgG deposits and linear IgG deposits couldn＇t be found in IgA nephropathy. Mean 20 months follow-up showed complete remission in 72.5% of HSPN, but only 19.4% in IgA nephropathy after 34 months follow-up. Moreover, 64.5 % of IgA nephropathy had consistent hematuria and proteinuria and 16. 1% had active nephritides （P〈0.05）. It was concluded that significant clinico-pathological difference was found between HSPN and IgA nephropathy, which didn＇t support the one disease entity hypothesis. HSPN and IgA nephropathy are probably two diseases with similar immune abnormalities.展开更多

Methods: A total of 70 children with purpura nephritis who were treated in the hospital between October 2013 and March 2017 were divided into control group (n=35) and Salvia Miltiorrhiza group (n=35) by random number table. Control group received routine + tripterygium wilfordii therapy, Salvia Miltiorrhiza group received routine+ tripterygium wilfordii + Salvia Miltiorrhiza therapy, and the therapies lasted for 3 courses. The differences in renal function, coagulation function and immune response were compared between the two groups before and after treatment. Results: Before treatment, there was no statistically significant difference in renal function, coagulation function and immune response function between the two groups. After 3 courses of treatment, renal function indexes CysC,β2MG and 24 h UmAlb levels in Salvia Miltiorrhiza group were lower than those in control group;coagulation function indexes FIB and D-D levels in peripheral blood were lower than those of control group;immune response indexes Th1 cytokines IL-2 and IFN-γ contents in peripheral blood were higher than those of control group whereas Th2 cytokines IL-5 and IL-10 contents were lower than those of control group. Conclusion: Tripterygium wilfordii combined with Salvia Miltiorrhiza therapy can effectively optimize the renal function, reduce the hypercoagulation state and reduce the Th1/Th2 immune imbalance in children with purpura nephritis.展开更多
