The incidence of breast cancer increased rapidly in recent years. Breast cancer has become the most frequent malignant tumor of female especially in the developed regions. Traditional Chinese medicine (TCM) is effective in treating breast cancer, but its theories appear hysteretic, restricting the progress in clinical practice, teaching and research of TCM in the treatment of breast cancer. This article described the significance and urgency to work out the standardization of syndrome differentiation based on stages for breast cancer and put it into practice. It also analyzed the foundations, ideas and approaches of the research of standardization of syndrome differentiation based on stages for breast cancer in light of the changes of spectrum of diseases, the weaknesses of modern medicine in treating breast cancer, and the existed problems in the update clinical practice.

The study on use of traditional Chinese medicine in perioperative management of breast cancer is still in the beginning phase. With the emergence of new understanding about the biological characteristics of breast cancer, the concept of treatment has changed. For instance, the resection extent is tending to be narrower, large doses of radiotherapy may be adopted during the operation, and early use of adjuvant chemotherapy is advocated after the operation. These have bought about changes to the intervention factors in the perioperative period for breast cancer. Some related problems about the participation of traditional Chinese medicine in perioperative management of breast cancer are discussed in this article, so as to make the perioperative management perfect.

Objective To explore the technique of breast reconstruction after mastectomy. Methods 30 cases of patients with breast cancer who were not suitable for breast conservative surgery were sum-marized. Among them, immediate breast reconstruction with prosthetic implants after mastectomy was used in 16 patients, transverse rectus abdominis musculocutaneous flap (TRAM flap) in 10 patients, and latissimus dorsi musculocutaneous flap in 4 patients. There were 27 patients who underwent immediate breast reconstruction, while 3 patients underwent delayed breast construction. Results The appearance was good in 16 cases of breast reconstruction with prosthetic implants and no complications were found. Two out of the ten patients who had the transevarse rectus abdominis musculocutaneous flap (TRAM flap) breast reconstruction had partly necrosis of skin flap, and one lateral ventral syndrome. The appear-ance of the 7 cases after the TRAM flap breast reconstruction evaluated well, 2 cases moderate, and one case less satisfactory. The appearance of 4 patients who had breast reconstruction with latissimus dorsi musculocutaneous flap evaluated well. Conclusion Breast reconstruction is an important part of combined therapy for the breast cancer, especially for the patients who have strong desire to conserve breast, while incompetence for breast conserving surgery. In such a case breast reconstruction is a good choice. Imme-diate breast reconstruction is better than delayed breast construction. The appropriate method of breast reconstruction depends on each individual patient. Patients with locally advanced breast carcinoma can se-lectively choose immediate breast reconstruction.

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.

Objective:To develop a role model education intervention model for male nursing students, and to explore the effect of role model education on male nursing students′ professional identity and positive psychological capital.Methods:A total of 60 male nursing freshmen were recruited and randomly assigned to the control group (n=30) and the experimental group (n=30) according to a 1:1 ratio. The control group only accepted the school′s routine teaching tasks and other campus activities. The experimental group received 6-week model education intervention on the basis of the control group once a week. Nursing students′ Professional Identity Questionnaire and Positive Psychological Capital Questionnaire were used for assessment at the time of enrollment and after intervention.Results:Male nursing students' professional identity (50.25±11.19) and positive psychological capital (114.68±29.08) were generally not high. After intervention, the scores of occupational self-concept, retention benefits and resignation risks, social persuasiveness and total score in the experimental group were 22.64±5.19,14.29±2.69,8.00±1.89,64.18±12.15, higher than those of the control group (20.07±3.16, 12.93±1.76, 6.86±1.24, 57.68±6.66), and the difference was statistically significant ( t value was 2.23-2.68, P<0.05). Conclusions:Role model education intervention has a good effect in promoting professional identity and positive psychological capital of male nursing students.
