Objective To investigate effects of hormone replacement therapy with conjugated equine estrogen (CEE) in different doses combined with medroxyprogesterone acetate ( MPA) on mammographic density among postmenopausal women and its clinical significance. Methods Ninety eligible postmenopausal women were randomized into three groups with varied treatment continuously for one year, Croup A receiving 0.3 mg CEE with 2 mg MPA and caltrate 600 mg and vitamin D 125 U daily; Group B receiving 0. 625 mg CEE combined with 2 mg MPA and caltrate 600 mg with vitamin D 125 U daily; and Group C receiving caltrate 600 mg and vitamin D 125 U daily. Mammographic density was analyzed using Wolfe and semi-quantitative methods for all of them and compared each other one year after treatment, as well as mammographic density before and after treatment in Groups A and B. Results One year after treatment, mammogrphic density reached the highest in postmenopausal woman of Group B and the lowest in those of Group C, with significant difference among the three groups (P ＜ 0. 01) and between Groups A and C (P ＜ 0. 01) and between Groups B and C ( P ＜ 0. 05 ). Mammogrphic density with semi-quantitative method increased significantly in Group A ( P ＜ 0. 05 ) and Group B ( P ＜ 0. 01 ), respectively, after treatment as compared with that before it. Change in mammografic density before and after treatment was greater in Group B than that in Group A, but not reaching statistically significant level (P ＞ 0. 05). Conclusions Hormone replacement therapy can cause the increase of mammographic density in postmenopausal women, possibly in a dose-dependent pattern, which suggest that HRT has side effect on breast tissue and the lowest effective dose of estrogen should be selected in HRT. Mammographic density can be used as an indicator to monitor side effect of HRT on breast.

ObjectiveTo explore the role of CXCL16/CXCR6 axis on the metastasis of human lung cancer.MethodsImmunohistochemistry and immunocytochemistry analysis were performed to detect the expression of CXCL16/CXCR6 in human lung cancer samples as well as A549,95D and H292 cell lines,respectively.The effects of CXCL16 on the viability and invasiveness of the three lung cancer cell lines were examined by MTT and in vitro invasion assay,respectively.ResultsHuman native lung cancer cells co-expressed CXCR6 and CXCL16 protein.Compared to the normal lung tissues,there was a stronger specific staining for both CXC16 and CXCR6 protein in the lung cancer tissues.Three kinds of lung cancer cell lines,including A549,95D and H292,all expressed CXCL16 and CXCR6 protein.Furthermore,human recombinant CXCL16 significantly promoted the viability and invasiveness of A549,95D and H292 cells.The stimulated action of CXCL16 on lung cancer cell lines could be effectively blocked by CXCL16 neutralizing antibody.Conclusion CXCL16 and CXCR6 protein are co-expressed in human native lung cancer.CXCL16 is able to promote the viability and invasiveness of lung cancer cell lines,which might be the molecular mechanisms on the metastasis of lung cancer.

Objective To evaluate the diagnostic values of MSCT for detecting atherosclerotic plaques on New Zealand rabbits models in comparison with pathologic results. Methods Fifteen New Zealand rabbits were enrolled in this study, including 5 with balloon injury and high-fat diet ( group A), 5 with high-fat diet only (group B) and 5 with regular feed (group C). 16th week late, contrast-enhanced MSCT scan was performed in all rabbits with 16 slice MSCT (16-MSCT) in group A and 64 slice MSCT (64-MSCT) in group B and C. The CT and pathological findings were compared in a double-blind manner. The sensitivities and specificities of 16-MSCT and 64-MSCT for detecting atherosclerotic plaques were evaluated by using Fisher test and x2 test. Results Sixty and seventy-five images on 16-MSCT and 64-MSCT had corresponding pathological slices. The sensitivities for the detection of plaques on 16-MSCT and 64-MSCT were 41.5% (22/53) and 64. 9% (24/37), and spocificities of 85. 7% (6/7) and 89. 5% (34/38), respectively. Conclusions 64-MSCT has a higher sensitivity in the detection of atherosclerotic plaques than 16-MSCT. Both scanners can be used to preclude the diagnosis of atherosclerosis.
