BACKGROUND: Renal tubulointerstitial fibrosis is mainly featured as the accumulation of extracellular matrix (ECM) in renal interstitium. The tubular epithelial-myofibroblast transdifferentiation (TEMT) is important to the pathogenesy of renal tubulointerstitial fibrosis. OBJECTIVE: To examine the effects of sodium ferulate (SF) on TEMT, and ECM main components such as collagen Ⅰ, collagen Ⅲ and fibronectin, in rat renal tubular epithelial cellsinduced by transforming growth factor-beta 1 (TGF- β1)- DESIGN: Randomized and controlled experimental study based on cells. SETTING: Department of Kidney in West China Hospital of Sichuan University. MATERIALS: Rat renal tubular epithelial cells (NRK-52E) originated from American Type Culture Collection (ATCC), were offered by the laboratory of Department of Nephrology in Australian Monash Medical Center. Cell strain used in this study was cultured at the 36th passage. SF white crystal with water solubility and more than 98.0% purify, was from Chengdu Hengda Pharmaceutical Co., Ltd. Different concentrations of SF (125,250, 500μreel/L) were designed in this study. Rabbit anti-rat α-smooth muscle actin (α -SMA) was produced by Wuhan Boster Company. Enzyme-linked immunosorbent assay (ELISA) kit was the produced of Shanghai Senxiong Science and Technology Co.,Ltd. Human recombinant TGF- β1 was produced by R&D Company. DNA Engine OpticonTM real-time fluorescence quantitative polymerase chain reaction apparatus was the product of MJ Research Company. METHODS: Rat renal tubular epithelial cells (NRK-52E) cultured in vitro were divided into five groups. Control group was added with serum-contained DMEM; TGF-β1-induced group was added with TGF-β1 at final concentration of 5 ng/L; SF at different concentrations groups were added with 125, 250, 500 μ mol/L SF and TGF- β1 at final concentration of 5 ng/L,respectively. MAIN OUTCOME MEASURES: The contrast phase microscope, real-time fluorescence quantitative polymerase chain reaction and ELISA method were used to detect TEMT of NRK52E cells induced by TGF-β1 and levels of collagen Ⅰ, collagen Ⅲ and fibronectin in the supernatant. RESULTS: Morphology of NRK52E cells: Compared with control group, TGF-β1 could induce the transdifferentiation of NRK52E cells, showing fibroblast-like in morphology after 3 days, which were previously the typical road stone-like epithelial cells. In three different concentration SF groups, the morphologic transformation stimulated by TGF-β1 could be partly ameliorated in a dose-dependent manner. Expression of α-SMA mRNA: Compared with control group, 5 ng/L TGF- β1 enhanced expression of α-SMA at 6 hours, and reached a peak at 72 hours; SF depressed the expression in a dose-dependent manner at 72 hours (P < 0.05). Changes of ECM: After induced by 5 ng/L TGF- β1 for 72 hours, the levels of collagen Ⅰ, collagen Ⅲ and fibronectin in the supernatant increased significantly (P < 0.05), whereas SF decreased these levels in a dose-dependent manner (P < 0.05). CONCLUSION: TGF- β1 induces the TEMT, and promotes the secretion of collagen Ⅰ, collagen Ⅲ and fibronectin. SF can inhibit TGF- β1-induced TEMT In a dose-dependent manner.

BACKGROUND:The faults or defects in pharmaceutical dosage form designed for carbamazepine may lead to irregular drug absorption, great individual differences between the pharmacokinetics, narrow therapeutic concentration range, and the therapeutic drug monitoring for this drug. OBJECTIVE:To prepare a magnetic/pH double sensitive hydrogel beads carrying carbamazepine and to evaluate its properties. METHODS:Using chitosan, alginate and Fe3O4 nanoparticle as carrier materials, the magnetic/pH double sensitive hydrogel beads carrying anti-epileptic carbamazepine were prepared, and the composition and preparation technology were optimized by orthogonal test of L9(34). The surface morphology and structure of the hydrogel beads were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy respectively. Also, the superparamagnetism, swel ing and release in vitro of hydrogel beads were determined. RESULTS AND CONCLUSION:The optimized preparation technology were described as:0.5%(w/v) chitosan, 1.5%(w/v) alginate, 2.0%(w/v) calcium chloride, and 1:2 ratio for magnetic versus carrier materials. The hydrogel beads under the optimal preparation conditions showed a round shape and smooth surface, and average encapsulation efficiency, loading efficiency and hydrogel beads diameter were 94.36%, 25.05%and 1-2 mm respectively. The hydrogel beads appeared to have superparamagnetism, the swel ing degrees were associated with pH value of medium, and the sequential release amount of carbamazepine from the hydrogel beads in simulated gastric fluid was 22.77%for 2 hours. Then, the beads were moved to the simulated intestinal fluid, and this value approached 91.63%for 24 hours. Experimental findings indicate that, the composition and preparation technology of magnetic/pH double sensitive hydrogel beads carrying carbamazepine was rational and feasible, and hydrogel beads show obvious pH sensitivity and magnetic sensitivety. The control ed-release effect of hydrogel beads in vitro is also good.

Aim To investigate the effects of iptakalim(IPT),a novel K_(ATP) opener,on the functions of endothelin system in human pulmonary artery endothelial cells.Methods Primary cultured human pulmonary artery endothelial cells were incubated with different concentrations iptakalim for 24 h.The levels of ET-1 in medium were observed by radioimmunoassay.Reverse transcription polymerase chain reaction(RT-PCR)was performed to analyze the expression of ET-1 and ECE.Results When endothelial cells were incubated with IPT at concentrations above 10 μmol·L~(-1),the levels of ET-1 release in medium and the levels of ET-1 mRNA were significantly inhibited.When endothelial cells were incubated with IPT at concentrations above 1 μmol·L~(-1),the levels of ECE mRNA were significantly inhibited.Conclusions IPT can inhibit the expression of ET-1 and ECE mRNA from human pulmonary artery endothelial cells, thus it inhibits the secretion of ET-1 from endothelial cells. Iptakalim may serve as a promising candidate drug to treat pulmonary hypertension.
