By aggregating the essence of theories related with depressive syndrome from historical medical practitioners and based on the extensive clinical experience,traditional Chinese medicine(TCM)master Lin Yi proposed the theory of six-stagnation-based breast disease prevention and treatment.She pointed out that the occurrence of breast diseases is related to six stagnations(qi stagnancy,blood stagnancy,phlegm stagnancy,dampness stagnancy,food stagnancy,and fire stagnancy),and the treatment for breast diseases should start from the six stagnations.The development and progression of breast cancer is closely associated with the imbalance of internal environment and the formation of six stagnations,and breast cancer is one of the major diseases suitable for the TCM syndrome differentiation and treatment.For the treatment of early breast cancer,Professor Lin Yi proposed to divide early breast cancer into four stages,namely perioperative period,peri-chemotherapy period,peri-radiotherapy period,and consolidation period.Guided by the theory of six-stagnation-based breast disease prevention and treatment,therapies of soothing the liver,resolving phlegm,removing stasis,clearing heat,eliminating dampness,promoting digestion,fortifying the spleen,and tonifying the kidney are employed to harmonize the internal environment and alleviate symptoms.The theory of six-stagnation-based breast disease prevention and treatment enriches the TCM theory for the prevention and treatment of breast cancer,refines the principles and methods for the staging and syndrome differentiation of early breast cancer,and holds significant implications for enhancing the efficacy of integrated TCM and western medicine in managing early breast cancer.

This article summarized the clinical experience of Professor LIN Yi in applying the idea of disease-syndrome-syptom combination to the differentiation and treatment of breast cancer in consolidation phase. It is believed that the fundamental pathogenesis of breast cancer in consolidation phase is deficiency of healthy qi， so the treatment should emphasize on reinforcing healthy qi as the main and eliminating pathogen as the supplement. Commonly， Sijunzi Decoction （四君子汤）， Shenling Baizhu Powder （参苓白术散）， and Liuwei Dihuang Decoction （六味地黄汤） are used as the basic formula to strengthen the spleen and kidney to reinforce healthy qi， and Baihua Sheshe Cao （Scleromitrion diffusum ［Willd.］ R.J.Wang）， Yiyiren （Coix lacryma-jobi L.）， and ezhu （Curcuma aromatica Salisb.） are used to eliminate cancer toxin. It is also believed that the biological characteristics of different molecular subtypes of breast cancer are of great significance to the syndrome differentiation and treatment in traditional Chinese medicine， therefore， the formulas used in clinical practice are often selected taking into considerations of molecular subtypes of breast cancer. For those with positive sex hormone receptor， the most important thing is to replenish the congenital and benefit kidney essence， with modified Baihua Qiqi Decoction （白花芪杞汤）； for those with negative sex hormone receptor， the first step is to strengthen spleen and replenish kidneys， and it is especially important to strengthen the spleen with Baihua Qiling Decoction （白花芪苓汤）. At the same time， it is suggested that the primary and the secondary symptoms of patients should be differentiated， and the diseases and symptoms， as well as the modern medical laboratory indicators should be combined to give suitable medication.

In view of the difficulties and blind spots of western medicine, how to make scientific decisions to standardize the treatment of breast cancer in traditional Chinese medicine and improve the participation of traditional Chinese medicine in the treatment of breast cancer is an important focus of innovative breakthroughs in breast cancer treatment. Based on the clinical experience of Professor LIN Yi, a master of traditional Chinese medicine, and on the basis of "disease identification and syndrome differentiation", this paper summarizes and refines the status of qi and blood imbalance, accumulation of phlegm and blood stasis, viscera deficiency, and cold heat cementation in breast cancer, and further proposes the "six views" of breast cancer balanced treatment: the pathogenesis view focuses on "evil invasion due to vital qi deficiency, and the proliferation of tumors", and the pathogenesis view focuses on "cancer toxin and imbalance of yin and yang", the diagnostic view focuses on "examining the underlying factors and understanding the causes and effects", the differentiation view focuses on "balancing qi, blood, yin, and yang to achieve harmony", the therapeutic view focuses on "supporting vital qi and eliminating evil, and considering the root cause and syndromes", and the rehabilitation view focuses on "adjusting balance to maintain a stable state". We are committed to holistic syndrome differentiation and treatment, balancing yin, yang, qi, and blood, thereby harmonizing the internal environment of the human body, and mobilizing the immune and rehabilitation functions of the body.

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.

Disdvantages of chemotherapy in treating breast cancer were insensitivity or intolerance.There were different opinions on chemotherapy in treating negative axillary lymph notes or positive hormone receptors after breast cancer surgery.The advantages of TCM in treating breast cancer were:there were many Chinese medical oncologists who had rich clinical experiences in treating breast cancer before and during surgery,before and during chemotherapy,before and during radiotherapy and during the consolidation period;treatment according to syndrome differentiation with TCM for different stages of breast cancer had been gradually standardized;a well developed network of academic information provided a good platform for establishing the unified treatment protocols with TCM for different stages of breast cancer.It was indicated that large scale prospective clinical trials with TCM in the treatment of after-surgery breast cancer patients who had negative auxillary lymph notes and positive hormone receptors should be carried out.
