Chinese Journal of Immunology 2016;32(12):1753-1757
Objective:To investigate the role of mTOR in regulation of ICOS expression in human blood regulatory T cells. Methods:Isolation of Treg cells from human PBMC using MACS beads. We detected the ICOS expression on purified Treg cells and Treg cells viability using flow cytometry in anti-CD3 plus anti-CD28 ( antibody or beads) or anti-CD3 plus ICOSL-Fc for 3 days and 7 days. CFSE labeling human PBMC cells and in vitro cultured Treg mixed, Treg contact inhibition activity was detected by flow analysis. Results:After in vitro stimulation of Treg cells in the presence of anti-CD3+anti-CD28 for 3 days, there was no significant statistic difference in viability between ICOS+(92. 00±2. 69)% and ICOS-(90. 30±3. 53)% Treg-cells. After cultured for 7 days,the decreased ICOS+ Treg cells percentage within total Treg cells from ( 40. 20 ± 1. 83 )% to ( 11. 60 ± 1. 10 )% compared with that of 3 days. Further more,the ICOS expression level between stimulated with anti-CD28 or ICOSL-Fc condition group,compared with the ICOS MFI in the condition of anti-CD3 plus anti-CD28 treatment for 3 days was (2410. 0±746. 4) obviously higher than (403. 30±74. 42), that of the group treated with anti-CD3 plus ICOSL-FC. Rapamycin could partially suppress Treg cells ICOS expression,but unaffected the Treg suppression ability. Conclusion:ICOS expression level may not important for in vitro cultured human PBMC Treg cells survival although mTOR signling is important for regulation ICOS expression on in-vitro cultured Treg cells,but the ICOS expression on Treg regulated by multiply signaling pathways. CD28 signaling is the key stimulation factor for ICOS upregulation on in-vitro cultured Treg cells compared to ICOSL signaling.

OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.
METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.
RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.
CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

OBJECTIVE: To verify the biocompatibility between diamond-like carbon (DLC) film and human vascular endothelial cells and to provide evidences for construction of artificial mechanical valve prosthesis. METHODS: Nanophase DLC film was deposited using pulse laser deposition, while vascular endothelial cells derived from human umbilical vein was cultured with nanophase DLC film in vitro. Cell growth and adhesion were observed under inverted microscope, and cell proliferation was measured with MIT method. In addition, levels of nitric oxide (NO) and prostacyclin (PGI2) were measured in the DLC group and blank control group in order to evaluate their activities. RESULTS: Adhesion, proliferation, and growth of vascular endothelial cells derived from human umbilical vein were great on the surface of nanophase DLC film. There were no significant differences in the levels of NO and PGI2 between DLC group and blank control group (P > 0.05), showing that nanophase DLC film had no effect on activity of vascular endothelial cells derived from human umbilical vein. CONCLUSION: Nanophase DLC film has a good biocompatibility, and it can become an ideal material of tissue-engineering artificial mechanical valve prosthesis.
