Objective To investigate curative efficacy of tetramethylpyrazine in combination with chemotherapy in treatment of medium and advanced liver cancer and its effects on level of brain-derived neurotrophic factor ( BDNF).Methods 90 patients of medium and advanced liver cancer who received therapy from January 2011 to June 2012 were selected as research objects.According to therapeutic schemes, those patients were divided into the control group (n=42) and the observation group (n=48).The control group was treated with transcatheter hepatic arterial chemoembolization ( TACE) , while the observation group was treated with tetramethylpyrazine in combination with TACE.Then, the short-term curative efficacy, long-term curative efficacy, level of BDNF and adverse reactions were compared.Results The total short-term therapeutic efficacy ratio in the observation group was statistically higher than that in the control group ( 83.3% vs 64.3%, P <0.05 ).During the three-year follow-up, the one-year and two-year survival rate in the observation group was statistically same with that in the control group respectively (75.0% vs 66.7%, 66.7% vs 59.5%), while the three-year survival rate was statistically higher than that in the control group (52.1%vs 30.9%, P<0.05).After treatment, in comparison with the control group, level of BDNF in the observation group was statistically lower(P<0.05).During treatment, incidences of liver function deterioration, abdo minal pain and diarrhea, nausea and vomiting, fever and headache in two groups were statistically same.Conclusion Tetramethylpyrazine in combination with TACE is effective for medium and advanced liver cancer, which can increase short-term and survival rate to some extent, significantly reduce level of BDNF with not increasing incidence of adverse reactions.

With the mutual communication and penetration of traditional Chinese medicine and modem medicine,the combination of traditional Chinese and western medicine is common in clinical practice.However,since western-style doctor is usually lack of traditional Chinese medicine theory knowledge,many problems exist in the combination of Chinese and western medicine.The problem that Chinese medicine containing ephedra alkaloids in combination with western medicine in pediatric medicine is especially serious.Because of the complexity of the children's drugs,improper use of the ephedra alkaloids is prone to adverse reactions.A comprehensive analysis of drugs containing ephedra alkaloids existing in the pediatric clinical application is performed,and in order to provide guidance for clinical rational drug use.
