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.

Epstein-Barr virus (EBV)infection is highly prevalent in general population,serum EBV antibody can be detected in about 90% of the adults.Forty years of researches have demonstrated that EBV infection is closely related to a variety of hematological diseases,such as infectious mononucleosis, EBV-related lymphoproliferative disorders,lymphoma and hemophagocytic syndrome.This paper reviews EBV-associated hematological diseases and its pathogenic mechanism.

OBJECTIVE: To investigate the effect of LARS artificial ligament on reconstruction of anterior and posterior cruciate ligament of keen joint.METHODS: Articles addressing reconstruction of anterior and posterior cruciate ligament by LARS artificial ligament were retrieved from VIP database (http://www.cqvip.com/) with the key words of "LARS artificial ligament, cruciate ligament,reconstruction" in Chinese between January 2000 and February 2010.Inclusion criteria: advantages and disadvantages of reconstructing anterior and posterior cruciate ligament by LARS artificial ligament; clinical application of reconstructing anterior and posterior cruciate ligament by LARS artificial ligament.Exclusion criteria: Duplicated studies or old references were excluded.A total of 31 articles were included in the final analysis.RESULTS: Reconstruction of anterior and posterior cruciate ligament by LARS artificial ligament characterized by convenient operation, short operative time, mild trauma, engaging in movement early, great strength, simple implantation, and reliable fixation; however, most patients were not able to bear the high medical cost, thus clinical application was limited.Scholars thought that LARS artificial ligament had great effects on reconstruction of anterior and posterior cruciate ligament.CONCLUSION: Patients who had multi-ligament injury, overhauling of ligament, and early movement were treated with LARS artificial ligament.

Objective To obtain the elasticity value of non-mass-like breast lesions with supersonic shear wave elastrography (SWE), in order to observe the value of quantitative elastography with SWE in differential diagnosis of non-mass-like breast lesions. Methods SWE was performed in 80 non-mass-like breast lesions. Taking pathologic results as reference, quantitative elasticity value of the lesions were performed. The diagnostic accuracy, sensitivity and speciifcity were calculated. Results In the 80 non-mass-like breast lesions, 37 lesions (46%) were malignant and 43 lesions (54%) were benign. The max and mean elasticity value of malignant lesions were (106.28±46.39) kPa and (51.02±30.06) kPa, and the max and mean elasticity value of benign lesions were (37.13±18.22) kPa and (26.44±15.62) kPa. There was statistical differences between malignant and benign lesions in max and mean elasticity values (t=15.328, 18.149, both P<0.05). Taking 61.25 kPa as the threshold of max elasticity value and 40.65 kPa as the threshold of mean elasticity value, the diagnostic accuracy, sensitivity and speciifcity were 70.53%, 66.83%, 51.22%and 68.34%, 65.81%, 50.63%, respectively. When max elasticity was combined with conventional ultrasound (US), the diagnostic accuracy, sensitivity and speciifcity were 84.17%, 92.28%and 68.39%, respectively. The diagnostic accuracy and speciifcity signiifcantly increased compared with conventional US (χ2=5.217, 9.652, both P<0.05). When mean elasticity was combined with conventional US, the diagnostic accuracy, sensitivity and speciifcity were 82.35%, 90.66%, and 63.35%, respectively. The diagnostic accuracy and speciifcity signiifcantly increased compared with conventional US (χ2=5.084, 8.686, both P<0.05). Conclusions The diagnostic accuracy and speciifcity of SWE for non-mass-like breast lesions are not high. But when SWE is combined with conventional US, the diagnostic accuracy and speciifcity increase signiifcantly, which is very helpful for the diagnostic of non-mass-like breast lesions.

BACKGROUND: The small change of the membrane potential (Em) of vascular smooth muscle cells (VSMC) could result in significant alteration in tension, and the membrane depolarization was closely associated with the development of hypertension.OBJECTIVE: To study the resting Em of VSMC from the middle cerebral artery (MCA) of stroke-prone spontaneously hypertensive rats (SHRSP) and the reactivity of Em to KCl and norepinephrine (NE).DESIGN: An animal experiment of comparative analysis.SETTING: Institute of Materia Medica, Shandong Academy of Medical Sciences.MATERIALS: Eighteen male SHRSP and 26 male Wistar rats were used.METHODS: ① Rats in both groups were anesthetized with intraperitoneal injection of ethyl carbamate (1 g/kg), the brains were removed quickly, and the Em of VSMC was recorded by intracellular microelectrodes. ② The effects of different concentrations of KC1 (10, 20, 50 mmol/L) and NE (10-7,10-6, 10-5 mol/L) on the Em of VSMC were observed.MAIN OUTCOME MEASURES: ① Em of VSMC in both groups; ②Effects of different concentrations of KC1 and NE on the Em of VSMC.RESULTS: ① The Em was obviously lower in SHRSP than in the Wistar rats [(-48.2±3.1), (-64.4±4.3) mV]. ② Both KC1 (10, 20, 50 mmol/L)and NE (10-7, 10-6, 10-5 mol/L) could cause the depolarization of Em of MCA in a concentration-dependent manner. The reactivity to MCA of SHRSP was obviously increased as compared with the Wistar rats.CONCLUSION: The resting Em of VSMC from the MCA of SHRSP was lower, and the reactivity of VSMC to KCl and NE was significantly stronger than that of Wistar rats.
