Objective To research the possible mechanism of Ganfujian Formula(formula for liver recovery)for liver fibrosis.Methods The SD rats were randomized into the normal group
model group
Ganfujian Formula low-dose group
Ganfujian Formula middle-dose group
Ganfujian Formula high-dose group and colchicines group
with 10in each.The liver fibrosis model was established with intraperitoneal injection of 0.5ml pig serum twice weekly for 8weeks in each group except the normal group.Both the normal and model groups were gavaged with 10ml/kg normal saline respectively.The Ganfujian Formula low-dose
middle-dose and high-dose groups were gavaged with 1.4g/ml
2.8g/ml and 4.2g/ml Ganfujian Formula decoction respectively.The colchicine group was given 0.154mg/kg suspension liquid of colchicine tablets.The expressions of leptin mRNA and leptin receptor(OB-Rb)mRNA were detected with reverse transcription-polymerase chain reaction.The expressions of Janus kinase 2(JAK-2)and signal transducer and activator of transcription 3(STAT3)were detected with Western blot.Results Comparing with the normal group
the expressions of leptin mRNA
OB-Rb mRNA
JAK2and STAT3were significantly increased in other groups(P<0.05).Comparing with the model group
the expressions of leptin mRNA
OB-Rb mRNA
JAK2and STAT3were significantly decreased in the Ganfujian Formula low-dose
middle-dose and high-dose groups and colchicine group(P<0.05)
especially in the Ganfujian Formula high-dose group(P<0.05).Conclusion The possible mechanism of Ganfujian Formula for liver fibrosis is inhibiting the expressions of leptin and OB-Rb and thereby inhibiting JAK2/STAT3signaling pathway.
