ABSTRACT
Objective · To investigate the relationship between the mammographic signs and the pathological features in breast cancer. Methods · From August 2015 to August 2018, 300 patients with primary breast cancer confirmed by operation and pathology in Shanghai First Maternity and Infant Hospital, Tongji University were selected. All patients had mammography before operation. The relation between characteristics of molybdenum target imaging and pathological types were retrospectively analyzed. The correlation between specific imaging signs such as lump, calcification, spiculation sign and important pathological features were further analyzed. Results · Among 300 cases of breast cancer, 251 cases (83.7％) had lumps, of which 183 cases had spiculation sign, and 190 cases had calcification. Besides, 235 cases (78.3％) had calcification; 77 cases (25.7％) had structural disorder with diffuse density; 98 cases (32.7％) had positive signs of vascular symptoms. Lump (95.1％), spiculation sign (82.3％) and calcification (83.7％) were mostly observed in invasive ductal carcinoma. Structural disorder (88.2％) was mostly observed in invasive lobular carcinoma. Calcification (96.1％) and lump (60.8％) were mostly observed in intraductal carcinoma. Calcification (100.0％) was mostly observed in lobular carcinoma in situ. Lump was mostly observed in simple carcinoma, medullary carcinoma and mucinous adenocarcinoma. The positive expression rates of estrogen receptor (ER) and progesterone receptor (PR) were higher in patients with tumor lump＞5 cm than those with tumor lump ≤5 cm, but there were no significant differences (P=0.165, P=0.317). The positive rate of ER was 54.5％ and the positive rate of PR was 60.8％ in patients with calcification, which were lower than those without calcification (P=0.027, P=0.006). The positive rate of PR in patients with spiculation sign was 71.6％, which was higher than those without spiculation sign (P=0.018). But there was no significant difference in the expression of ER in patients with or without spiculation sign (P=0.321). Patients with lumps alone had a lower incidence of lymph node metastasis (29.5％ vs 37.9％, P=0.009), and lower histological grade (P=0.043), in comparison with patients with lumps and calcification. But they had higher ER positive rate (70.5％ vs 57.9％, P=0.033) and PR positive rate (73.8％ vs 65.3％, P=0.014).Conclusion · Breast cancer patients with different pathological types show different signs of mammography which may have certain associations with the expression of immunohistochemical indicators such as ER and PR. Simple lump shadows in mammography may be a predictor in the good prognosis of breast cancer.
ABSTRACT
As a topical plaster developed by modern pharmaceutical technology based on traditional Tibetan medicine,Cheezheng Xiaotong Tiegao has functions of promoting blood circulation,relieving swelling and relieving pain. Since its introduction in 1993,it has been widely used in the treatment of various types of acute and chronic musculoskeletal pain and various types of spinal,joint and soft tissue diseases. In order to better standardize the clinical application and improve the clinical efficacy of Cheezheng Xiaotong Tiegao,the research and development work of the Experts consensus statement on Cheezheng Xiaotong Tiegao in clinical practice was officially launched on October 19,2017,upon approval from China Association of Chinese Medicine. In this paper,main R&D process and related technical links for the experts consensus on Cheezheng Xiaotong Tiegao would be summarized,which will help the various medical workers understand,master and apply more accurately,and also provide reference for the development of experts consensus on clinical application of other topical Chinese medicines.

Hedgehog signaling pathway is excessive activated in breast cancer.LKBl is currently accepted as a tumor-suppressor gene,which can inhibit the proliferation of breast cancer.The overexpression of LKB1 can regulate the expression of CyclinDl series gene which is a target gene of Hedgehog signaling pathway.Meanwhile,the study found that PKA gene play an important role in Hedgehog signaling pathway,its activation is related with the cAMP state,and LKB1 genes can influence the cAMP state.Therefore,LKB1 gene and the Hedgehog signaling pathway may exist some inevitable connection.
