Objective: The aim of this study was to investigate the effect of co-culture with AEC (amniotic epithelial cell) on the biological characteristics of AMSC (amniotic mesenchymal stem cell), and to investigate the roles of SDF-1/CXCR4 axis in the homing and migration of AMSC. Methods: AMSC andAEC were isolated from human amnion, and then cultured, amplified and identified, respectively. TheAMSC were divided into three groups:AEC co-cultured group, serum-free cultured group and serum cultured group.After culture for 24 h, 48 h, and 72 h, the proliferation viability ofAMSC was measured by CCK-8 assay and trypan blue staining; the expression of CXCR4 mRNAwas analyzed by flow cytometry and Real-time RT-PCR, and the migration ability ofAMSC in vitro was observed by migration assay. Results: Cell viability (48 h and 72 h) and survival rate in the co-culture and serum groups were higher than those in the serum-free group (all P<0.05). The mRNA and protein expressions of CXCR4 in AMSC of the co-culture and serum-free groups were significantly higher than those of the serum group (P<0.05). The migration ability of AMSC in the co-culture and serumfree groups, which increase with the SDF-1 (stromal cell derived factor-1) concentration gradient, were higher than that in the serum group (P<0.05). Conclusion: AMSC co-cultured with AEC still have the basic biological characteristics of MSC, and showed good growth activity. Co-culture withAEC can up-regulate CXCR4 onAMSC surfaces and enhance the migration ability ofAMSC in vitro.

Purpose To investigate the value of low dose CT combined with iterative model reconstruction (IMR) technique for evaluation of both breast lesion and pulmonary metastasis in patients with breast cancer,and compare the effects of IMR,hybrid iterative reconstruction (HIR) and filtered back projection (FBP) techniques on image quality.Materials and Methods Twenty-one patients with solitary tumor confirmed by mammography and/or ultrasonography at Navy General Hospital from January to May in 2016 were enrolled,and the related breast imaging reporting and data system reached to level 4 and above.All patients underwent dynamic contrast-enhanced CT with different tube current for breast (scanning 6 times within 6 minutes) and chest scans;the conventional tube current (61 mAs) was used at the 2 minutes phase after injection,and the low tube current (10 mAs) was used at the other 5 phases.CT images were reconstructed with FBP,HIR and IMR techniques,respectively.The images of breast lesions and chest in 2 minutes scans were evaluated objectively and subjectively.Results The mean effective radiation dose was (2.15 ± 0.39) mSv.The images of 3 reconstruction techniques at the 2 minutes phase were compared,and the IMR images showed the lowest image noise and the optimal contrast to noise ratio (P＜0.05).The images quality of 3 kinds of reconstruction techniques was acceptable,of which IMR was better than HIR and FBP (P＜0.05).Conclusion Low dose CT scan combined with IMR technique can remain low radiation with dose of 2 mSv,while maintaining good image quality,which can be used for preoperative evaluation of both breast lesion and pulmonary metastasis in patients with breast cancer.

Objective To compare the effects of different blood purification methods on the removal of large and medium molecular toxins in patients with maintenance hemodialysis(MHD), and to provide the clinical basis for selecting suitable dialysis modalities to prevent or delay the long term complications of uremic patients.Methods60 MHD patients with long term and stable hemodialysis were enrolled in this study.All of them were selected from the patients with insufficient hemodialysis.According to the digital table,60 patients were randomly divided into high flux hemodialysis (HFHD)group and hemodiafiltration (HDF) group,30 cases in each group.And before,3 months and 6 months after dialysis, the serum β2-MG,PTH and Cys C after dialysis were tested.Results The clearance of PTH in the HFHD group[(286.34±127.33)pg/mL] was significantly higher than that in the HDF group[(376.04±141.74)pg/mL],the difference was statistically significant(t=2.45,P<0.05).The clearance of β2-MG in the HDF group[(11.34±1.96)mg/L]was significantly higher than that in the HFHD group[(15.41±3.02)mg/L],the difference was significant(t=5.88,P<0.05).The clearance of Cys C in the HFHD group[(263.67±98.72)μg/dL]was significantly higher than that in the HDF group[(345.63±105.00)μg/dL],the difference was statistically significant(t=2.96,P<0.05).Conclusion Both two dialysis methods are very effective in the removal of large and medium molecular uremic toxins in patients.In the removal of patients with increased PTH,HFHD is more effective.In the removal of patients with increased β2-MG,HDF is more effective.In the removal of Cys C,HFHD is better.
