Objective:To assess the ability of axillary reverse mapping (ARM) to identify and preserve the arm lymphatics drainage as well as determine its ability to reduce lymphedema. Methods:A total of 300 breast cancer patients who underwent axillary lymph node dissection (ALND) from June 2009 to May 2011 were enrolled in this study. Methylene blue dye (2 mL to 3 mL) was injected into the ipsilateral upper inner arm along the medial intramuscular groove to map the upper extremity lymphatic drainage system prior to ALND. The blue lymphatic and lymph nodes were identified and preserved during the operation. The change in the arm circumference was the selected method of measurement. The difference in the bilateral upper arm circumference was recorded after 2 months (difference≥2 cm is defined as lymphedema). Results:The ARM was performed successfully in 195 (65%) of 300 patients. The incidence of lymphedema was significantly lower in the successfully mapped patients than in the failing mapping patients, with statistically significant difference during follow-up at 6, 12, 18, and 24 months post operation. Conclusion:The ARM technique can identify and preserve the arm lymphatics drainage and prevent upper extremity lymphedema after breast cancer axillary lymphadenectomy.

Background The pathogenesis of age-related cataract is associated with the apoptosis of lens epithelial cells (LECs) caused by oxidative stress.Previous studies showed that intracellular focal adhesion kinase (FAK) pathway can be activated by H2O2 in vitro,which induced apoptosis of cells.To investigate the effect of oxidative on FAK expression in LECs is one of important studies in the prevention of age-related cataract.Objective This study was to investigate the expression and function of FAK in human LECs treated by H2O2.Methods Human LECs strain (HLECs-B3) were cultured in vitro in the low glucose DMEM with 10％ fetal bovine serum.Different concentrations (0,30,50,70,100,300,500,700,1000 μmol/L) of H2O2 were added into the culture medium for 24 hours.The survival rate of the cells was detected by Cell Counting Kit-8 (CCK-8) assay.Cell morphology as well as the expression and distribution of FAK in the cells were observed by immunofluorescent staining under the laser confocal microscope.Apoptosis was observed by hoechst33258 staining,and Western blot assay was used to quantitatively detect the expression and phosphorylation of FAK.Results The survival rate of the cells was (1.00±0.03) ％,(1.24±0.03)％,(1.36±0.24) ％,(0.93±0.02)％,(1.75±0.19)％,(1.37±0.18) ％,(0.64±0.01)％,(0.59±0.11)％,(0.14±0.05)％ in 0,30,50,70,100,300,500,700,1000 μmol/L H2O2 groups,with a significant difference among them (F =95.30,P =0.00).The survival rates of the cells in the below 300 μmol/L H2O2 groups were significantly higher than those in the 0 μmol/L H2O2 group,and survival rates of the cells in the above 500 μmol/L H2O2 groups were significantly lower than those in the 0 μmol/L H2O2 group(all at P＜0.05).After H2 O2 treatment for 24 hours,HLECs-B3 cells transformed from polygon shape to spindle shape and extended pseudopodiums,meanwhile the green fluorescence for FAK exhibited in the cytoplasm.Cell apoptosis was found in the 1000 μ mol/L H2O2 group.Western blot assay revealed that the expressing levels (grey scale) were significantly different among the various groups (F=28.08,P=0.00),and FAK expressing levels in the below 300 μmol/L H2O2 groups were significantly higher than those of the 0 μmol/L H2O2 group; while the expressing levels in the above 500 μmol/L H2O2 groups were lower than those of the control 0 μmol/L H202 group (all at P＜0.05).After treated by different concentrations of H2O2,the phosphorylation level of intracellular FAK (p-FAK) was significantly higher in 3 hours group than that in 30 minutes group (all at P＜0.05).Conclusions H2 O2 can affect the survival,proliferation and morphology of human LECs by activating the intracellular FAK pathway,indicating that FAK may play roles in the regulation process of cell biological behavior.

Background Protein kinase B (Akt) is the center of multiple cellular signaling pathways,and it participates in the regulation of cell function,such as proliferation,migration,and metabolism of cells.Phosphoinositide 3-kinase (PI3K) promotes activation of Akt and therefore triggers many signal pathways.PI3K inhibitor can silent Akt,but whether it can affect the biological behavior of lens epithelial cells (LECs) during the posterior capsular opacity (PCO) is worthy of investigation.Objective This study was to explore the effect of LY294002,a PI3K inhibitor,on Akt activation in human LECs.Methods Human LECs strain,HLEC-B3 cells,were cultured and passaged.The cells were incubated to 96-well plate for 24 hours,then LY294002 was added with the final concentration at 0,10,20,30,40,50,60,70,80 μmol/L,respectively.After incubation for 24 hours,cell counting kit-8 (CCK-8) was used to detect the inhibitory rate of cell proliferation.Transforming growth factor-β2 (TGF-β2) of 10 μg/L was added in the medium of cells as TGF-β2 group,TGF-β2 + LY294002 (20 μmol/L) was used to coculture the other group of cells,and the cells without TGF-β2 and LY294002 served as the control group.Phosphorylation of Akt (p-Akt) in the cells was detected by laser scan confocal immunofluorescence microscope.The expression level of p-Akt was evaluated using Western blot.Results CCK-8 assay showed that the A value of the cells was gradually reduced with the increase of LY294002 concentration (Fgroup =9.72,P =0.00),but the A value was significant raised along with the lapse of time (Ftime =1737.54,P=0.00).Confocal immunofluorescence revealed that a little of p-Akt was expressed in the control cells.After induced by TGF-β2,lots of red fluorescence of p-Akt was seen in cells around the cell membranes.But in the TGF-β2+LY294002 co-culture cells,the fluorescence of Akt was much weaker.Western blot showed that the expression level of p-Akt was 0.91±0.08,1.48±0.13 and 0.95±0.19 in the control group,TGF-β2 group and TGF-β2 +LY294002 group,respectively,with a significant difference among the three groups (F =15.04,P =0.00).Conclusions LY294002 can inhibit the activation of Akt induced by TGF-β2.LY294002 may have utility in the prevention and treatment of PCO.
