In this paper, taking one of the typical dome-like structures in the Xuefengshan orcline （e.g. Moping dome-like structure） as an example, based on its structural framework interpratatoin, superposed deformation analysis and paleo-stress fields reconstruction, we propose the Moping dome- like structure is composed of two populations of different-striking thrust-fold structures, -E-trending and NE-striking structures, indicative of two-stages shortening, -N- and NW-striking, respectively. Together with the geochronological analysis, we suggest the first stage of shortening occurred in Late Triassic to Early Jurassic, due to the Indosinian intercollisional orogeny of the Yangtze Block and the North China Block. The second occurred during Late Jurassic-Early Cretaceous owing to Yanshanian intracontinental orogeny, leading to the intensive superposition of the NE-trending structures onto the -E-trending structures, and the final ocurrence of the Moping dome. Thus, our study indicates the Xuefengshan arc-shape belt also experienced two-phase deformation, and resulted from the superposition of NE-SW structures onto -E-W structures in Late Jurassic-Early Cretaceous, which could provide new structural evidence for probing the Mesozoic tectonic framework and evolution of the Xuefengshan orocline.展开更多

Their plasma were tested for viral loads (VL): before and repeatedly during the treatment. The regimen was: MSAMS (50 mg/kg), MSAMS-stabilized Ampicillin trihydrate (7.5 mg/kg) and immunace extra protection?. After 4 weeks, it was reduced to 50 mg/kg (MSAMS) and the immune stimulant. When VL decreased bellow 50/ml, the treatment continued, 4 weeks before stopping. Mean-VL of four patients increased (P = 0.006) from 498.50 ± 33.37 to 1,072.50 ± 184.55, after 3.75±2.06 weeks and decreased (P = 0.040) to 407.33 ± 297.27 (18.29%) when the treatment-duration increased to 6.67 ± 2.31 weeks. Prolonging the duration to 12.00 ± 2.83 weeks led to 98.68% decrease of mean-VL of four other patients, from 24,250.00 ± 15,939.34 to 321.00 ± 229.38(P = 0.045). Two HIV positive persons treated for 4 weeks after their VL reduced bellow 50/ml have remained healthy, 10 and 16 months respectively, without routine antiretroviral medication.展开更多
