[Herbs for calming liver and suppressing yang in treatment of hyperthyroidism with hyperactive liver yang: herbal...

To observe the herbal effects on hyperthyroidism patients with syndrome of hyperactivity of liver-Yang by method for calming the liver and suppressing Yang and investigate its effects on the lymphocyte protein expression. This approach may lay a foundation for the further investigation of the curative mechanisms of calming the liver and suppressing Yang treatment.

A total of 48 hyperthyroidism patients with syndrome of hyperactivity of liver-Yang were randomly divided into treatment group and control group. The treatment group was treated by method for calming the liver and suppressing Yang in accordance with traditional Chinese medicine (TCM) and the control group with thiamazole tablets for three periods of treatment The therapeutic effects, the score of TCM symptom, electrocardiogram (P wave), thyroid hormones and ultrasound were observed in both groups before and after the treatment. The side effects in the treatment course were observed in both groups. The level of differential protein expression was analyzed by two-dimensional electrphoresis and matrix assisted laser desorption/ionizaton time-of-flight mass spectrometry.

The treatment group has the effect on stepping down the heart rate, cutting down the P wave amplitude changes, regulating the level of thyroid hormones and decreasing the volume of thyromegaly. There are not statistically significant between the treatment group and control group. However, the treatment group has obviously better effect on regulating TCM symptom and decreasing the side reaction than the control group (P<0.05). There are not statistically significant on the total effective between the treatment group and control group. The average spots in lymphocyte for normal people, before and after treating hyperthyroidism patients with syndrome of hyperactivity of liver-Yang were (429 +/- 31), (452 +/- 28) and (437 +/- 36) spots respectively. Eight down-regulated protein expressions and 11 up-regulated protein expressions were obtained in the hyperthyroidism patients with syndrome of hyperactivity of liver-Yang and normal people. Five strengthened expressions of protein were also obtained in 8 down-regulated expressions of protein and 8 lower expressions of protein in 11 up-regulated expressions of protein before and after treating the migraine patients with syndrome of hyperactivity of liver-Yang. Ten of the total 8 differential protein spots were successfully identified by MALDI-TOF-MS. The functions of these proteins were involved in metabolism associated, transportation, antioxidation, sigal transduction and immume associated protein, etc. according to information provided by NCBI and MSDB database.

In this study, the TCM complex prescription with herbs for calming the liver and suppressing Yang can regulate the thyroid hormones, improves TCM symptoms, and decrease the adverse reaction. It can possibly regulate lymphocyte protein expression.
