RESUMO
OBJECTIVE:To compare the anti-inflammation,analgesia effects of decoctions extracted from Aconiti lateralis with different leaf shapes(dahua leaf,xiaohua leaf)from different producing areas(Jiangyou,Butuo). METHODS:Animals were randomly divided into blank group(distilled water),positive group,groups of Aconiti lateralis with dahua,xiaohua leaf from Ji-angyou,groups of Aconiti lateralis with dahua,xiaohua leaf from Butuo(with dose of 5 g/kg,calculated by crude drug). The an-ti-inflammation effect of decoctions extracted from Aconiti lateralis with different variety sources and leaf shapes was investigated by xylene-induced ear swelling test (n=12) in mice and egg white-induced toe swelling test (n=10) in rats (positive drug was Dexamethasone acetate tablet,0.005 g/kg). And its analgesic effect was investigated by acetic acid-induced writhing body reaction test(n=12)and hot-plate-induced pain test(n=12)in mice(positive drug was Morphine hydrochloride tablet,0.0025 g/kg). RE-SULTS:The decoctions extracted from Aconiti lateralis with dahua,xiaohua leaf from Butuo and xiaohua leaf from Jiangyou can significantly reduce the ear swelling degree(P<0.01). The decoctions extracted from Aconiti lateralis with dahua leaf from Jiangy-ou and Butuo can significantly decrease the toe swelling degree after 6 h of medication(P<0.05). And decoctions extracted from Aconiti lateralis with xiaohua leaf from Butuo can significantly reduce the number of writhing body in mice with acetic acid-in-duced pain and prolong the pain threshold of mice with hot-plate-induced pain (P<0.05 or P<0.01). CONCLUSIONS:Aconiti lateralis with dahua and xiaohua leaf from Butuo and with xiaohua leaf from Jiangyou show better anti-inflammation effect,and Aconiti lateralis with xiaohua leaf from Butuo shows better analgesic effect.
RESUMO
Objective To explore the relationship of molecular biology characteristic and the treatment outcome,and influence factors of neoadjuvant chemotherapy (NAC) in inflammatory breast cancer (IBC).Methods The clinicopathological data of 103 IBC patients who were treated with NAC from January 2005 to June 2013 were analyzed retrospectively.Immunohistochemical method was used to detect the expression of estrogen receptor (ER),progesteron receptor (PR),human epidermal growth factor receptor 2 (HER-2) and E-cadherin.The treatment outcome were evaluated.Results In 103 IBC patients,ER negative was 48 patients,PR negative was 51 patients,HER-2 positive was 45 patients,E-cadherin positive was 66 patients.The effective rate of chemotherapy was 72.8％ (75/103).The effective rate of chemotherapy in taxane-based group was significantly higher than that in anthracycline-based group [80.6％ (50/62) vs.61.0％(25/41)],and there was significant difference (P ＜ 0.05).The effective rate of chemotherapy in ER,PR,E-cadherin negative patients was significantly higher than that in ER,PR,E-cadherin positive patients [83.3％ (40/48) vs.63.6％ (35/55),82.4％ (42/51) vs.63.5％ (33/52),83.8％ (31/37) vs.66.7％ (44/66)],and there was significant difference (P ＜ 0.05).The effective rate of chemotherapy in taxane-based group with E-cadherin positive patients was significantly higher than that in anthracycline-based group with E-cadherin positive patients [77.5％ (31/40) vs.50.0％ (13/26)] (P ＜0.05).No correlation existed between the expression of HER-2 and the treatment outcome of chemotherapy (P ＞ 0.05).Conclusion ER,PR and E-cadherin negative patients with IBC is chemosensitive to NAC.The positive expression of E-cadherin may be an important factor of chemotherapy resistance.For the patients with E-cadherin positive,taxane-based chemotherapy regimen can achieve a better effective rate.
