Effect of triptolide on expression of oxidative carbonyl protein in renal cortex of rats with diabetic nephropathy.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f., TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.

[Clinical Effect of Treating Refractory Pressure Ulcers by Jinchuang Ointment].

Objective To observe the clinical effect of Jinchuang Ointment (JO) for treatment of refractory pressure ulcers. Methods Totally 306 patients with phase II , IIl, IV refractory pressure ul- cers were randomly assigned to the traditional Chinese herbal medicine ointment group, the JO group, the MepilexAg group,102 cases in each group. Each ulcer was scored using pressure ulcer scale for healing (PUSH) designed by National Pressure Ulcer Advisory Panel (NPUAP) before treatment, at day 7, 14, and 21 after treatment, respectively.

Effects and clinical significance of pentoxifylline on the oxidative stress of rats with diabetic nephropathy.

Diabetic nephropathy (DN) is a common and serious clinical complication of diabetes and presently there are no effective ways to prevent its occurrence and progression. Recent studies show that pentoxifylline (PTX) can improve renal hemodynamics, reduce urinary protein excretion, and alleviate or delay renal failure in DN patients. In this study, we focused on the anti-oxidative stress effect of PTX on alleviating renal damages of DN using rat models.

Construction of bioartificial renal tubule assist device in vitro and its function of transporting sodium and glucose.

To explore a new way of constructing bioartificial renal tubule assist device (RAD) in vitro and its function of transporting sodium (Na(+)) and glucose and to evaluate the application of atomic force microscope in the RAD construction, rat renal tubular epithelial cell line NRK-52E was cultured in vitro, seeded onto the outer surfaces of hollow fibers in a bioreactor, and then cultured for two weeks to construct RAD. Bioreactor hollow fibers without NRK-52E cells were used as control. The morphologies of attached cells were observed with scanning electron microscope, and the junctions of cells and polysulfone membrane were observed with atomic force microscope.
