Clinically, patients with IgA nephropathy often have symptoms of sore throat or discomfort in the pharynx, which needs to be paid attention to. Traditional Chinese Medicine has certain effect in the treatment of IgA nephropathy, starting from the pharynx.There are many commonly used herbal medicines that could relieve wind, clear heat, detoxify the body and relieve sore-thoat, such as platycodon grandiflorum, dandelion, burdock and other herbs, and pecking treatment could be added to increase the curative effect.

The molecular targeted therapy method using microRNAs(miRNAs)is gradually stepping into people′s vision. miRNAs affect colorectal cancer progress via abnormal expression in tumor cells or micro-environment. The high or low expressions of miRNAs in specific tissues probably have an impact on the expressions of oncogenes,tumor suppressor genes or other aspects including the surrounding environments,the metastases and the drug tolerance of tumors,thus contributing to curing the colorectal cancer. Nowadays, miRNA has entered the stage of animal experiments.

Objective To study the effects of 5-azacytidine’s demethylation for P16 gene on hemangioma cell’s proliferation and apoptosis.Methods Bisulfite sequencing PCR was applied to detect P16 gene′s promoter methylation status in 5-azacytidine treated and untreated EOMA cell line.RT-PCR and western blot were used to detect the P16 gene mRNA and protein expressions.Flow cytometry was used to detect cell proliferation, cell cycle and cell apoptosis.The differences of P16 gene′s promoter methylation status,mRNA and protein expressions,cell proliferation,cell cycle and apoptosis in two groups were compared. Results The methylation rates in 1st and 13th CGs were 0%after 5-azacytidine treatment in EOMA hemangioma cell line,which were lower than in untreated cells.The mRNA and protein expressions increased after 5-azacytidine treatment,which were significantly higher than in untreated cells.The absorbance,S phase and G2/M phase and PI after 5-azacytidine treatment were lower than untreated cells,while the G0/G1 phase and apoptosis rates were higher.Conclusion The P16 gene promoter is hypermethylated in hemangioma cells with silent gene expressions.5-azacytidine could reverse P16 gene′s promoter methylation and silent gene expressions,which inhibit hemangioma cell’s proliferation and promote apoptosis.

Objective To study the effects of Lentinan on bleomycin A5’s inhibition effects in hemangioma-derived endothelial cell. Methods Hemangioma-derived endothelial cell line EOMA were divided into LTN group (only lentinan treatment), BLE group (only bleomycin A 5 treatment), L+B group (Lentinan and bleomycin A5 treatment) and CON group (no lentinan and bleomycin A5 treatment). Cell proliferation, cell cycle, PI and apoptosis were detected and compared among four groups. Results The differences of absorbance in LBE group was significantly higher than that in L+B group after treatment for d 1-d 7 (P<0.05), but both of them were significantly lower than in CON group and LTN group (P<0.05). The G 0/G 1 stage and apoptosis rate in L+B group was significantly higher than in BLE group(P<0.05), while it was significantly lower in S stage, G 2/M stage and PI(P<0.05). Conclusion Lentinan could significantly promote bleomycin A5’s inhibition effects on hemangioma-derived endothelial cell.

Objective To explore the molecular effect and interaction among nephrin, podocin, CD2AP and ?-actinin-4. Methods Firstly, the recombinant RNA interference (RNAi) plasmid-psiRNA-hH1GFPzeo, specifically targeting to the mRNA of nephrin, podocin, CD2AP or ?-actinin-4, was respectively tansfected into the mouse podocyte clone (MPC5) to each knockdown (KD) the expression of nephrin, podocin, CD2AP or ?-actinin-4. Molecular distributions were revealed by confocal microscopy, and the mRNA and protein expressions were detected with semi-quantitative RT-PCR and Western blotting. Results (1)In podocin KD group (siPod966 and siPod54), the mRNAs of podocin and nephrin were not detected, their protein decreased 92% and 79%, 82% and 67%, respectively. The mRNA and protein level of CD2AP increased 62% and 42%, 71% and 46%, respectively, whereas ?-actinin-4 did not change. In nephrin KD group (siNep492), the mRNA expression and protein level of nephrin were not detected, CD2AP increased 35% and 48%, respectively; and whereas podocin and ?-actinin-4 did not change. In CD2AP KD group (siCda744 and siCda21), the mRNA of expression CD2AP was not detected, and its protein level decreased 92% and 83%, the mRNA and protein of nephrin decreased 60% and 48%, 76% and 72%, respectively; podocin increased 38% and 22%, 56% and 44%, respectively; whereas ?-actinin-4 did not change. In ?-actinin-4 KD group (siAct1790 and siAct319), the mRNAs expression of ?-actinin-4 and nephrin decreased 69% and 58%, 64% and 49%, respectively; their protein level decreased 81% and 55%, 71% and 64%, respectively. However, the mRNAs of podocin and CD2AP increased 50% and 34%, 45% and 28%, respectively; and their protein level increased 64% and 46%, 65% and 42%, respectively. (2) With their expression change, the distributions of nephrin, podocin and CD2AP shifted evidently from the cell membrane surface to the nucleus circumference, whereas ?-actinin-4 showed no change, which was still localized in the cytoplasm and further extended to foot processes. Conclusion (1) Nephrin might more independently play a crucial role in the slit diaphragm complex. (2) Alpha-actinin-4 might interact direcdy or indirectly with nephrin, podocin and CD2AP. (3) The relationship among these podocyte molecules might not be spontaneous, either a single-directional or bi-directional reaction. (4) The normal localization of these podocyte molecules might depend on their normal expression quantity.
