Reversible watermarking is suitable for hiding data in 2-D vector maps because the distortions induced by data embedding can be removed after extracting the hidden bits. In this paper, two reversible data-hiding schemes are explored based on the idea of difference expansion. The first scheme takes the coordinates of vertices as the cover data and hides data(More)
Accumulating evidence suggested that macrophages induce tubulointerstitial injury. Total glucosides of paeony (TGP), extracted from Paeonia lactiflora, has presented anti-inflammatory activities in diabetic kidney disease. This research will investigate the protective effect of TGP on renal tubulointerstitium and its mechanism in streptozotocin-induced(More)
TLRs are a family of receptors that play a critical role in the pathogenesis of diabetic nephropathy. TGP have been shown to have anti-inflammatory and immuno-regulatory activities. However, the relation between TGP and TLRs on diabetic nephropathy remains unknown. In this study, we examined effects of TGP on immune regulatory TLR2 and 4 in the kidney from(More)
Breviscapine is a flavonoid extracted from a Chinese herb Erigeron breviscapus, previously it was shown that treatment with breviscapine attenuated renal injury in the diabetic rats. The purpose of this study was to investigate whether breviscapine combined with enalapril (an ACE inhibitor) have superior renoprotective effects against diabetic nephropathy.(More)
Toll-like receptors (TLRs) may be involved in diabetic nephropathy (DN). Paeoniflorin (PF) is an effective Chinese traditional medicine with anti-inflammatory and immunoregulatory effects that may inhibit the TLR2 signaling pathway. In this study, we investigated the effects of PF on the kidneys of mice with streptozotocin-induced type 1 diabetes mellitus(More)
OBJECTIVE To study the expressions and clinical significances of p-extracellular regulated kinase(P-ERK)1/2 and matrix metalloproteinase-9(MMP-9)in cervical squamous cell carcinoma. METHODS The expressions of P-ERK1/2 and MMP-9 in 30 cases with chronic cervicitis, 45 cases with cervical intraepithelial neoplasia (CIN), and 58 cases with cervical squamous(More)
