Objective: To explore the advantages and evaluate feasibility of sentinel lymph node (SLN) biopsy and axillary lymph node dissection under mastoscopy for patients with early stage breast cancer in clinical diagnosis and treatment. Methods: 200 patients with breast cancer stage I and II diagnosed by breast surgery were divided into observation group (100 cases) and control group (100 cases) as different surgery method. The patients of observation group were treated by SLN biopsy and axillary lymph node dissection under mastoscopy, while those of control group were treated by traditional open surgery. To analyze the detection rate and accuracy rate, and compare the bleeding volume during operation, the operation time and hospitalization time between the two groups. And series of indexes, such as incidence of post-operative complication, recurrence rate and good appearance rate of breast were compared between the two groups. Results: The difference of accuracy rate between the two groups was no significant. The incidence of complication, good appearance rate of breast and recurrence rate of observation group were, respectively, 4%, 92% and 4%. And the differences between those results of observation group and those of control group were significant (x2=25.25, x2=16.61, x2=170.40; P<0.05). Other some indexes, such as the bleeding volume during operation, the operation time and hospitalization time, the differences between observation group and control group also were significant (t=9.73, t=13.86, t=11.66; P<0.05). Conclusion:Sentinel lymph node (SLN) biopsy and axillary lymph node dissection under mastoscopy are feasibility in clinical practice based on its series advantages, such as better detection rate, lower incidence of complication, better protection for breast appearance and so on.

The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malig nant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.

Objective To investigate the alteration of mood and hippocampal microglia morphology in a mouse model of chronic inflammatory pain induced by complete Freund' s adjuvant (CFA). Methods Thirty-two male ICR mice were randomly divided into two groups, including normal saline control group (NS) and CFA model group (CFA). The pain model was established by right hindpaw intraplantar CFA injection. The change of mechanical pain threshold after CFA injection was measured by von Frey fiber needle, the locomotor activity and anxiety-like behavior were determined by open field test (OFT), the depression-like behavior was determined by sucrose preference test (SPT) and forced swimming test (FST). The expression of microglia marker ionized calcium binding adaptor molecule-1 (IBA-1) in the hippocampus was determined by immunohistochemistry and its morphological change was analyzed by Sholl analysis. Results Compared with the NS group, the mechanical pain threshold of CFA group decreased significantly (P<0.01). The behavior result showed that the CFA group showed remarkably reduced time in the inner area (P<0.01) compared with the NS group in the open field test; In the sucrose preference test, the percentage of sucrose preference (P<0.01) of CFA mice decreased significantly compared with the NS mice, while the immobility time of CFA mice (P<0.01) increased significantly in the forced swimming test compared with the NS mice. The immunohistochemistry showed that the number of microglia in the dentate gyrus (DG) of CFA mice increased significantly compared with the NS mice. The Sholl analysis result showed that compared with the NS mice, the number of intersections of microglia in hippocampal DG decreased significantly in CFA mice. Conclusion Our finding indicates that the negative emotions in CFA-induced chronic inflammatory pain may be related to the morphological changes of hippocampal microglia in the mice.
