Background and purpose:Studies have shown that renin-angiotensin system (RAS) is closely associated with tumor progress. angiotensinⅡ (AngⅡ) is the most important component of RAS. This study aimed to investigate the possible mechanism by which AngⅡ affected the cell proliferation in human breast cancer cell line MCF-7.Methods:CCK-8 was used to investigate the cell proliferation alteration of MCF-7 cells after treatment of AngⅡ at different dose and time. The inlfuence of losartan (an AT1R inhibitor) and PD98059 (a MAPK inhibitor) in AngⅡ-enhanced cell proliferation was detected by CCK-8. Protein expression was analyzed by Western blot.Results:AngⅡ stimulated the growth of breast cancer cells in a dose- and time-dependent manner. The maximal proliferation effect on MCF-7 cells was obtained with 10-7 mol/L AngⅡ and 24 h, respectively (P<0.000 1). Losartan signiifcantly decreased the level of AngⅡ-induced proliferative effects (P<0.05). Western blot showed that AngⅡ caused rapid activation of p-ERK. In addition, PD98059 could signiifcantly suppress AngⅡ-promoted cell proliferation.Conclusion:AngⅡ can promote MCF-7 cell proliferation through AT1R/ERK/MAPK pathway activation, which could be reversed by losartan or PD98059. Therefore, targeting AngⅡ/AT1R/MAPK signaling could be a novel therapeutic for breast cancer.

Objective To explore the expression of KAI1/CD82,E-cadherin and β-catenin in endometrial carcinoma,and to investigate their correlations to clinicopathological parameters of endometrial carcinoma. Methods The expressions of KAI1/CD82,E-cadherin and β-catenin in 76 specimens of endometrial carcinoma,15 specimens of atypical endometrial hyperplasia and 20 specimens of proliferative endometrium were examined by immunohistochemical envision technique.Their correlations to clinicopathological parameters of endometrial carcinoma were statistically analyzed. Results Compare to normal proliferative phase endometrium and atypical endometrial hyperplasia,the expression of KAI1/CD82 in endometrial carcinoma was significantly decreased(P ＜0.01),the abnormal expression of E-cadherin and β-catenin in endometrial carcinoma were significantly higher(all P <0.01).In endometrial carcinoma,the expression of KAI1/CD82 was negative correlated with histological grade and depth of myometrial invasion(P <0.01,P <0.05); The abnormal expression of the E-cadherin is related to histological grade and type(P <0.01,P<0.05); The abnormal expression of β-catenin was positively correlated with histological grade and FIGO stage(P ＜0.01 ,P <0.05).The down-regulation expression of KAI1/CD82 was closely associated with the abnormal expression of E-cadherin and beta-catenin in endometrial carcinoma(P <0.01,P <0.05). Conclusion The down-regulation of KAI1/CD82 and the aberrant expression of E-cadherin and β-catenin could be involved in the development of endometrial carcinoma.The loss or reduced expression of KAI1/CD82 was closely associated with the abnormal expression of E-cadherin and β-catenin in endometrial carcinoma.

OBJECTIVE: To measure the upper airway of obstructive sleep apnea-hypopnea syndrome by speed CT. We can predict the airway obstruction plane with the airway plane data and compliance in OSAHS patients. Through this measurement, we can provide assistance for clinical diagnosis and treatment. METHOD: This study randomly selected 82 patients diagnosed with OSAHS and 45 cases non-snoring healthy people as control group by the PHILIPS 256-slice CT. The zone volume, sagittal diameter, coronary diameter and cross-sectional area of the narrowest plane in nasopharyngeal area, velopharyngeal area, glossopharyngeal area, hypopharynx area in two groups of quiet respiration and Müller's status were measured. RESULT: In the OSAHS group underwent quiet breathing and Müller movement during CT scanning, the two states about nasopharyngeal coronary diameter, the hypopharynx sagittal diameter and cross-sectional area showed no significant difference, while other groups showed differences between the parameters (P<0.05). There was significant difference (P<0.01) in the velopharyngeal volume, tongue sagittal diameter and volume. Under Müller movement in the OSAHS group and the control group, the hypopharynx volume showed no significant difference. The nasopharyngeal coronary diameter and volume, velopharyngeal cross-sectional area and tongue sagittal diameter were different (P<0.05). The remaining set of parameters showed significant differences (P<0.01). Compared the airway compliance (Müller phase) of the OSAHS group and the control group,the parameters of each group were different (P<0.05), of which the nasopharyngeal sagittal diameter, velopharyngeal volume showed significant difference (P<0.01). Meanwhile, in the same plane, coronary diameter was greater than sagittal diameter (P<0.05) in both the OSAHS group and the control group. The pharyngeal volume measurement was basically consistent to the fiber endoscopy. CONCLUSION The obstruction plate of OSAHS patients is mostly in the velopharyngeal area and glossopharyngeal area measured with a high speed CT. The volume measurement of upper airway with speed CT can predict airway obstruction plate in patients with OSAHS.
