Abstract: OBJECTIVE: To investigate the conventional ultrasound (US), contrast-enhanced ultrasound (CEUS) manifestations and the corresponding histopathological characteristics of patients diagnosed with breast encapsulated papillary carcinoma (EPC) and to explore the value of CEUS in diagnosis of EPC. METHODS: The clinical, pathological, US, and CEUS features of 16 patients (17 lesions) with EPC confirmed by postoperative histopathology were retrospectively analyzed. RESULTS: EPC was prevalent in the postmenopausal women. The majority of conventional US images of EPC showed complex cystic and solid masses with circumscribed margins (70.6%), enhanced posterior echo (94.1%), no sonographic calcification (88.2%), rich blood flow in …the solid components within lesions (70.6%) on Color Doppler flow imaging, and high resistance index of blood flow (94.1%). Moreover, CEUS showed mainly centripetal hyperenhancement of the solid components within the lesions with irregular outline, and the enhancement area of the whole masses was essentially the same as the B-mode US area. CONCLUSIONS: EPC typically presents as a complex cystic and solid mass. CEUS is helpful to clarify the extent of the solid component and facilitate preoperative core-needle biopsy. A comprehensive evaluation by CEUS is valuable for diagnosing EPC and combining it with clinical features are helpful to further improve the diagnosis of this rare kind of breast cancer. Show more

Abstract: OBJECTIVE: This study intends to explore the effects of Rosuvastatin on ox-LDL induced platelet activation and its molecular mechanism. METHODS: Platelet aggregation rate was detected by aggregometer. ELISA kit was used to detect the levels of cAMP. Immunofluorescence staining was used to detect the platelet adhesion. The expression levels of platelet surface markers CD62p and PAC-1 were detected by flow cytometry. The protein levels of p-p38, p-IKKa and p-IKKB in platelets were detected by western blot. RESULTS: We found that rosuvastatin significantly inhibited platelet aggregation and increased the level of cAMP in a dose-dependent manner. Immunofluorescence …staining results showed that rosuvastatin could inhibit platelet adhesion. Flow cytometry results showed that rosuvastatin could reduce the expression of platelet activation markers. Western blot results showed that rosuvastatin could down-regulate the expression levels of p-p38, p-IKKa and p-IKKb. CONCLUSION: Our study revealed the rosuvastatin could inhibit the aggregation, adhesion and activation of platelet induced by ox-LDL, its mechanism may be related to inhibition of p38/MAPK signal pathway.
