Objective To investigate the expression of LPS receptor-CD14(CD14) on the membrane of Kupffer′s cells (KCs) induced by Lipopolysaccharide (LPS )and its role in activation of KCs and production of cytokines. Methods KCs were isolated by collagenase perfused Wistar rats and routinely cultured in 24-well dishes for 12 h. Cells were harvested and adjusted to a concentration of 1×106/ml/well and were devided into two groups. Group of LPS: KCs were induced with different concentration of LPS (0, 100 ng/ml, 1 μg/ml and 100 μg/ml). Group of PI-PLC: KCs were pre-incubated for 30 min with one unit of phophatidy linositol specific phospholipase C (PI-PLC) before different concentrations of LPS were added. KCs were cultured for 30 and 60 min respectively. Supernatants were then collected for measuring the level of TNFα and IL-6. Cells were stained by indirect immunofluorescent method ( rabbit anti-CD14 antibody and goat anti-rabbit IgG conjugated with FITC ) and analyzed with flow cytometer (FCM). The percentage and mean fluorescence intensity (FI) of CD14-positive cells were taken as the indexes. Results In LPS group, after incubation of cells with increasing concentration of LPS, a significant increase in the percentage of CD14 positive KCs were found and the mean FI was stronger when compared with the control points or the group of PI-PLC. The levels of TNFα and IL-6 in supernatant also increased (P<0.01). In group of PI-PLC, decreased percentage of CD14 positive KCs and weakened mean FI were found when compared with group of LPS. The increasing production of TNFα and IL-6 slowed down in the group of PI-PLC. Conclusion CD14 expression of KCs might be up-regulated by LPS with increase of some cytokines. The production of cytokines in KCs induced by LPS is partially inhibited by PI-PLC.

Objective To determine the incidence of breast cancer?related lymphedema ( BCRL) in China and to analyze the associated risk factors. Methods A retrospective analysis was performed on the clinical data and the incidence of BCRL in 281 patients who were newly diagnosed with breast cancer and received surgery. The incidence of BCRL was evaluated using arm circumference measurement and Norman questionnaire. The risk factors for lymphedema were analyzed using chi?square test and logistic regression model. Results In all patients,the incidence rates of BCRL determined by arm circumference measurement and Norman questionnaire were 31?7% and 27?0%, respectively. The multivariate analysis showed that postoperative radiotherapy,a preoperative body mass index no less than 24 kg/m2 ,a large axillary lymph node dissection area,and a large number of positive axillary lymph nodes significantly increased the risk of BCRL (HR=2?87,P=0?042;HR=2?54,P=0?011;HR=1?97,P=0?037;HR=1?06,P=0?023). Moreover, patients with breast cancer and hypertension had 1?74?fold higher risk of BCRL than those with normal blood pressure. Conclusions The incidence of BCRL is still very high. However,most of patients only have mild edema. Postoperative radiotherapy, a large axillary lymph node dissection area, a large number of positive axillary lymph nodes,a high preoperative body mass index,and hypertension are risk factors for BCRL.
