Objective: To set up an HPLC method for the simultaneous determination of p-hydroxybenzoic acid plus o-hydroxy-benzoic acid and p-hydroxybenzeneacetic acid in Senecio scandens Buch. Methods:The column was a Shiseido( Fine Chemicals) Cap-cell Pak C18 (250 mm × 4. 6 mm, 5 μm) column at the room temperature. The mobile phase was methanol-water-formic acid (13∶87∶0. 5) at a flow rate of 1. 0 ml·min-1 . The detection wavelength was 240nm. Results: p-Hydroxybenzoic acid plus o-hydroxybenzoic acid had a favorable linear relationship within the range of 0. 025-0. 400 mg·ml-1 , the regression equation was Y=5. 94 × 106 X+2.46×104(r=0.9998),theaveragerecoverywas97.59% andRSDwas1.22%. p-Hydroxybenzeneaceticacidhadafavorableline-ar relationship within the range 0.05-0.80 mg·ml-1, the regression equation was Y=4.09 ×106X+1.12 ×104(r=0.999 8), the average recovery was 98. 07% and RSD was 1. 90%. Conclusion:The method is simple, feasible and reproducible. It can be used in the quality control of p-hydroxybenzoic acid plus o-hydroxybenzoic acid and p-hydroxybenzeneacetic acid in Senecio scandens Buch.

Objective To explore the relationship of thyrotropin receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) in patients with thyroid-associated ophthalmopathy ( TAO), and the role played by TRAb and sICAM-1 in the pathogenesis of TAO. Method Twenty-three TAO patients were assigned to groups according to the clinical activity score and EUGOGO. All patients were treated with intravenous methylprednisolone pulse. The levels of serum TRAb and sICAM-1 were evaluated by a competitive radioimmunoassay and enzyme-linked immunosorbent assay respectively before treatment and by the end of each methylprednisolone pulse. Results The differernce in serum TRAb levels was associated with activity scores of TAO (P=0. 020). The change in serum sICAM-1 was associated with durations of TAO ( P = 0.015). During methylprednisolone treatment in active TAO patients, the levels of TRAb kept on decreasing gradually and markedly declined after the third methylprednisolone pulse in active TAO patients (P＜0.05). The trends of changes in serum TRAb and sICAM-1 levels were both different in active and inactive TAO patients by tendency analysis. Conclusion TRAb level was related to the activity of TAO and might serve as a significant predictor of response to methylprednisolone therapy. The negative correlation between sICAM-1 levels and duration of TAO corroborates the role played by ICAM-1 during the early stage of TAO. Higher sICAM-1 levels are not expected to be specific to TAO and may not predict a response to methylprednisolone therapy.
