Abstract:
OBJECTIVE:To observe the expression of high mobility group box chromosomal protein 1(HMGB1) in RAW264.7 macrophages after interfering with burning serum and qinghuobaidu-yin (QHBDY), and to find out the endogenous protection mechanism of QHBDY resisting inflammation reaction.
METHODS:RT-PCR was used to detect the expression of HMGB1 in RAW264.7 macrophages after interfering RAW264.7 macrophages with normal SD rat serum, burning SD rat serum, and QHBDY feeding SD rat serum.
RESULTS:Small quantity of HMGB1 mRNA was expressed in RAW264.7. The expression of HMGB1 mRNA fluctuated around the standard level after interfering with normal serum of SD rats. The expression of HMGB1 mRNA rose at 3 h, and then decreased to the standard level; at 18 h, it rose rapidly; at 36 h, it reached the peak; and at 48 h, it remained at the high level after interfering with burning serum. The expression of HMGB1 mRNA increased at 3 h, and then decreased to the standard level. At 24 h, it started to rise after interfering with herb serum, and was lower than that of; the burning serum group (P<0.05).
CONCLUSION:Burning serum can increase the expression of HMGB1 mRNA in RAW264.7. QHBDY can decrease the high expression of HMGB1 mRNA in RAW264.7 caused by burning serum.
