[Analysis of professor Lin Yi's experience for metastasis breast cancer by data mining].

Data mining method based on the traditional Chinese medicine(TCM) inheritance system(V2.5) was adopted to analyze professor Lin Yi's experience for metastasis breast cancer(MBC) by analysing the high frequency medicine, drug categories，drug properties，the key symptoms and key drugs of different metastasis regions and different syndromes, drug symptom analysis in the effective prescriptions for treating MBC by Lin from January 2013 to December 2017. A total of 89 MBC patients, 5 syndromes and 117 prescriptions were involved. The first 10 most frequently used were Atractylodis Macrocephalae Rhizoma, Poria, Dioscoreae Rhizoma, Coicis Semen, Crataegi Fructus, Hordei Fructus Germinatus, Galli Gigerii Endothelium Corneum, Hedyotis Diffusa, Codonopsis Radix, Astragali Radix. The warm and placid property was higher, the most herbs had Gan taste, the first two channel tropisms were spleen and the stomach. Drug symptom analysis in 5 different metastasis regions and 6 different syndromes were also been done. The conclusion showed that professor Lin's experience as: recognizing the basis of diseases,differentiating the syndrome, combinating disease and syndrome, cautiously grasping pathogenesis,combinating tonification and purgation together, regulating balance, treating the symptoms and origin, regulating spleen and stomach, caring for the postnatal throughout, prefering ancient prescription,rational compatibility, using medicine gently.

[Features of preoperative contrast-enhanced ultrasound of breast cancer: relationship with the syndrome classification in traditional Chinese medicine].

OBJECTIVE: To analyze the relationship between the features of preoperative contrast-enhanced ultrasound and the differentiation of symptoms and signs for syndrome classification by traditional Chinese medicine (TCM). METHODS: Eighty-two patients with malignant breast tumor were examined with contrast-enhanced ultrasound before the operation. The tumor diameter was greater than 2.0 cm in 48 cases and below 2.0 cm in 34 cases. According to the curative effect standard of TCM disorder, differentiation of symptoms and signs for classification of syndrome were performed, and the ultrasonic manifestations of different syndrome types were compared. RESULTS: In patients with maximum tumor diameter < or = 2 cm, Chong and Ren disorder type and liver Qi stagnation type were prevalent. In those with tumor diameter of <2 cm, Zeyi liver Qi stagnation type and virtual drug junction were more common. The mass peak intensity, slope of increase, enhancement intensity index and time-intensity curve of ultrasound differed significant between different syndrome types (P<0.05). CONCLUSION: The preoperative ultrasound features of breast cancer are associated with the syndrome types in TCM.

[Effects of Runing Recipe II on expressions of p53 and ras oncogene proteins and cell cycle of the transplanted Ca761 breast cancer in mice].

OBJECTIVE: To explore the mechanisms of Runing Recipe II (a recipe composed of traditional Chinese herbs) in inhibiting the growth of breast cancer by observing its effects on the expressions of p53 and ras oncogene proteins and cell cycle of the transplanted Ca761 breast cancer in mice. METHODS: We established the breast cancer model by transplanting Ca761 cells in mice. The mice were randomly divided into 4 groups: normal saline control group, CTX-treated group, Runing Recipe II-treated group, and Runing Recipe II and CTX-treated group, with 12 mice in each group. We detected the cell cycle of the cancer cells in the mice's transplanted tumor with flow cytometry and measured the expressions of p53 and ras oncogene proteins in the transplanted tumor with immunohistochemical methods. RESULTS: The percentages of tumor cells in S-phase of the Runing Recipe II treated group, CTX-treated group and Runing Recipe II and CTX-treated group were significantly lower than that of the normal saline control group respectively (P<0.05). The percentage of tumor cells in G(0)-G(1) phase of the Runing Recipe II treated group was lower than that of the CTX-treated group (P<0.05), while the percentage of tumor cells in G(2)-M phase was higher than that of the CTX-treated group. The immunoreactive scores (IRSs) of p53 in the Runing Recipe II treated group and Runing Recipe II and CTX-treated group were significantly lower than that in the normal saline control group respectively (P<0.05). The effect of CTX on the expression of p53 was not significant. The IRSs of ras oncogene protein in the Recipe II-treated group, CTX-treated group and Runing Recipe II and CTX-treated group were lower than that in the normal saline control group respectively (P<0.05). CONCLUSION: Runing Recipe II can inhibit the growth of Ca761 breast cancer in mice by controlling the cell cycle of the transplanted tumor. This may be related to its effect on the gene expressions of p53 and ras in the tumor tissue.
