    Abstract Background: Over 20 kinds of steroids, tacrolimus ointments, and cyclosporine capsules are usually recommended for the treatment of atopic dermatitis (AD), depending on the symptoms of patients. However, several side effects sometimes occur with the extensive use of these agents for the treatment of pediatric AD patients. The purpose of this study was to explore whether vitamin K

    Abstract Disporopsis pernyi (Hua) Diels, which belongs to genus Disporopsis, has been widely used for the treatment of abnormal sweating, chronic cough, and so forth. An ultra-performance liquid chromatography (UPLC) analysis was developed for the determination of rutin, luteolin, quercetin, and betulinic acid in Disporopsis pernyi (Hua) Diels roots. UPLC analysis was conducted by using a Shim-pack XR-ODS column with gradient elution with the mobile phase of acetonitrile and water containing 0.1% formic acid and with a flow rate of 0.2 mL/min, detected at 210, 254, and 280 nm. The method was precise, with relative standard deviation < 2.0%. The recoveries for the four components in Disporopsis pernyi (Hua) Diels were between 98.5 and 100.9%. The average contents of rutin, luteolin, quercetin, and betulinic acid in roots were 5.63, 2.51, 3.87, and 2.41 μg/g, respectively. The method was accurate and reproducible and it can provide a quantitative basis for quality control of Disporopsis pernyi (Hua) Diels.

    Abstract Glucocorticoids play significant roles in treatments of inflammatory and autoimmune diseases. Some patients show a poor or absent response even to high doses of glucocorticoids. The purpose of this study was to explore whether tetrandrine combined with glucocorticoids could be a new treatment strategy to resolve glucocorticoids resistance. Information on glucocorticoids sensitivity was usually obtained through mitogen-activated human peripheral blood mononuclear cells in cell culture procedures. Thus, human peripheral blood mononuclear cells was chosen as a model to study the immunosuppressive effect of methylprednisolone combined with tetrandrine, including the possible action mechanisms. Tetrandrine decreased the IC

    Abstract Immunosuppressive therapy for prevention of acute rejection episode occasionally causes serious adverse effects, and thus it is important to develop new therapeutic approach for renal transplant recipients. This study evaluated the immunosuppressive pharmacodynamics of tetrandrine (TET) and/or methylprednisolone (MP) in haemodialysis patients in vitro by using the peripheral blood mononuclear cells (PBMCs) isolated from whole blood of haemodialysis patients. The median (range) of MP IC
