RESUMEN
Objective To screen out some Chinese medicines with obvious inhibitory actions on triple-negative breast cancer based on data mining. Methods Literatures of breast cancer effectively treated by Chinese medicine issued in recent 15 years were collected, and then the frequency analysis and cluster analysis were used to screen the frequently-used herbs. According to the above results, the serum containing the obtained drugs were prepared respectively. And then the proliferation, migration and invasion abilities of breast cancer cells MDB-MB-231 treated with the serum containing various Chinese medicines for 12, 24 h were observed by methyl thiazolyl tetrazolium(MTT) assay and transwell cell invasion and migration experiments, respectively. Results The frequently-used herbs were screened out as Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix Trichosanthis, Radix Achyranthis Bidentatae. The proliferation of MDB-MB-231 cells was significantly inhibited by serum seperately containing Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix Trichosanthis, and Radix Achyranthis Bidentatae to different degrees, and the migration abilities of MDB-MB-231 cells were obviously inhibited by serum containing Herba Taraxaci, Herba Hedyotis Diffusae, Radix Achyranthis Bidentatae, respectively. And the invasion abilities of MDB-MB-231 cells were obviously inhibited by serum containing Herba Taraxaci, Rhizoma Chuanxiong, Herba Hedyotis Diffusae, respectively. Conclusion Chinese medicines such as Rhizoma Chuanxiong, Herba Taraxaci, Herba Hedyotis Diffusae, Radix richosanthis, Radix Achyranthis Bidentatae obtained by data mining technology have obviously inhibitory effects on triple-negative breast cancer.
RESUMEN
Objective To compare effect of trichosanthin and methotrexate in the treatment of uterine scar pregnancy by a multi-center study. Methods 90 uterine scar pregnancy patients were selected from department of obstetrics and gynecology,in xinyang central hospital,the second affiliated hospital of zhengzhou university,zhumadian central hospital,using random number table divided into 2 groups.The control group of 45 cases were treated by methotrexate,gluteal muscle injection,50 mg one time,and took mifepristone 50 mg,two times a day,a week for a course of treatment;45 cases in the experimental group,were treated with trichosanthin,intramuscular injection of 1.2 mg/time,two times a day,and oral administration of bloven,0.6 g/d,a week for a course of treatment.The end of a course of treatment,2 groups of patients before and after treatment were compared of the serum progesterone level,β-HCG,side reactions after treatment.Results After treatment,progesterone levels were significantly reduced,and the experimental group levels were lower than the control group obviously,the difference has statistical significance(P<0.05).Serum -HCG level after the treatment significantly reduced,and the experimental group in serum -HCG levels were significantly lower,with statistical difference (P <0.05 ). Comparison of adverse reaction of the patients,the experimental group was obviously lower than control group,with statistically significant difference (P<0.05).Conclusion For the treatment of uterine scar pregnancy,trichosanthin and methotrexate have certain effect,but trichosanthin could lower serum progesterone,β-HCG levels more significantly than methotrexate,trichosanthin group side reaction rate is low.
