The cement paste jacking construction techniques after the bearing plates of interconnections between the steel tower and concrete cap

Zhang Ping,Jiang Jian,Dong Qinjun,Cai Wei,Liu Ying

Strategic Study of CAE 2010, Volume 12, Issue 4,   Pages 53-57

Abstract:

Taizhou Bridge is a three-tower, two-span suspension bridge with the herringbone middle tower in the longitudinal direction. The two oblique legs are anchored by screw bolts at the top of the concrete cap and the pressure plates of the D0 segment transmit pressure to the concrete cap. The top surface of concrete has bi-directional slope degrees. The space needed for concrete cement paste jacking is reserved at the top of the tower cap. After the segment D0 is installed, the concrete mud with high strength and no shrinkage is pressed into the space to form the supporting surface of the pressure plates. This paper briefly describes the concrete cement paste jacking techniques used in the construction procedure.

Efficacy and safety of JAK inhibitor INC424 in patients with primary and post-polycythemia vera or post-essential

Xin Du,Daobin Zhou

Frontiers of Medicine 2016, Volume 10, Issue 4,   Pages 437-443 doi: 10.1007/s11684-016-0472-9

Abstract:

A phase II study (A2202) was performed to evaluate the efficacy and safety of JAK inhibitor ruxolitinib in 63 Chinese MF patients. Ruxolitinib was given twice a day (bid) at a starting dose of 15 mg (n=25) or 20 mg (n=38) based on a baseline platelet count. About 94.7% of the patients achieved a reduction in spleen size, 27.0% of which exhibited significant reduction (≥35%) at week 24. Significant improvement in debilitating constitutional symptoms, as assessed by MFSAF v2.0, was observed in patients treated with ruxolitinib. Ruxolitinib treatment was generally well tolerated by Chinese patients. Although the treatment was associated with an increase in certain adverse events (AEs) that were established as identified risks (anemia and thrombocytopenia), these AEs were considered manageable in this clinical setting. Ruxolitinib provided substantial reductions in splenomegaly and improvements in symptoms, and was well-tolerated by Chinese patients with MF.
