PurposeTo evaluate the shear wave elastography in diagnosis of intraductal papillomas, benign or malignant breast lesions.Materials and Methods From December 2013 to December 2014, 145 female patients with 155 lesions who underwent ultrasonography and shear wave elastography in general hospital of PLA were retrospectively studied. All the lesions were confirmed by pathology via surgery or biopsy. The performance of the maximum elasticity, the mean elasticity, the minimum elasticity values and the elasticity ratio in diagnosis of benign and malignant tumors were analyzed. The portion of intraductal papillomas in misdiagnosed cases was calculated. The elasticity values of intraductal papillomas were compared with those of other breast benign and malignant lesions.ResultsAmong 155 lesions, pathology confirmed intraductal papillomas in 20 lesions, fibroadenosis in 23 lesions, fibroadenoma in 23 lesions, inflammation in 9 lesions, adenosis with fibroadenoma in 17 lesions, and breast cancer in 63 lesions. The maximum, mean, minimum elasticity values and the elasticity ratio of intraductal papillomas were (84.39±74.08) kPa, (51.33±46.36) kPa, (26.55±24.98) kPa and 2.80±2.18, respectively. The elasticity values of intraductal papillomas were between those of breast cancer and other benign lesions, and there were no statistically significant (P=0.003).ConclusionThe elasticity values of intraductal papillomas were between those of breast cancer and other benign lesions, which may be a potential reason to cause misdiagnosis using shear wave elastography to differentiate breast benign and malignant diseases.

Objective]The article summarizes the essentials of hyperprolactinemia infertility experience by Professor Wang Zhe. [Methods]From following Professor Wang Zhe clincial studies,summarize experience and thoughts of treating hyperprolactinemia infertility with a case. [Results]Professor Wang Zhe thinks the main reason for the occurrence of hyperprolactinemia infertility ,which is related to the dysfunction of the liver,spleen and kidney.The spleen rules transformation and transportation that like dryness and dislike dampness.The liver stores the blood and rules flowing and spreading, that is sensitive to boundaries and maintains the smoothness and harmony of movement throughout the body.The kidneys store the essence and rule birth and hiding, which is foundation of innate existence. Its main types are liver depression and deficiency of the kidney block and phlegm-dampness stagnation.Therapeutically,using Fu Qingzhu medicine for women in the study of Yangjingzhongyu Decoction and the Ye Tianshi treatment recipe for women refers to Cangfudaotan Decoction in the treatment,to achieve nourishing the liver and kidney, invigorating spleen for eliminating dampness.[Conclusion]Professor Wang has exquisite medical skills, rigorous academic attitude, and richly professional knowledge and clinical experience.She has unique insights and experience in treating hyperprolactinemia infertility.Professor Wang Zhe's experience hopes to expand ideas of the clinical diagnosis and treatment.

Objective: To examine the emotional states of asthmatic children with different degrees of severity, as well as the effects of emotion on change of cytokines in airway. Methods: Asthmatic children were divided into two groups according to the degrees of severity: moderate and mild. Their emotional states were measured and results were compared. Correlation analysis was conducted between scores on emotional scales and sputum levels of IL-8.Results: Total scores on anxiety and depression were higher in the moderate group than in the mild group. Negative correlation was found between levels of anxiety and IL-8 during acute exacerbation of asthmatic condition. Conclusion: Emotional distress was found to be increased with severity of asthmatic condition in children. Anxiety contributed to the decreased concentration of IL-8 in asthmatic children's airway.
