One is keeping the temperature at 950 ℃ and the annealing time of 100 h, varying the pressure (1035 GPa). The other is keeping the pressure at 30 GPa and temperature at 950 ℃, varying the annealing time (20300 h). The products are inspected with microscope and electron probe.

Methods The cells were divided into 5 treatment groups（10,25,50,75 and 100 μmol·L-1 QUE）, blank control and menstruum control group. The rat C6 cells were cultivated to 1×106·mL-1 in the RPMI 1640 medium, then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h. The change of cell cycle was also observed by flow cytometry after the cells were treated with 50 and 100 μmol·L-1 QUE for 48 h. The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 μmol·L-1 QUE for 48 h were detected by immunocytochemical methods.

RESULTS: Both resting B cells and T cells did not express PD-L1 on their surface, however PD-L1 expression was significantly up-regulated on the surface of the activated B cells after 6 h stimulation with LPS or pokeweed mitogen, and the percentages of B cells that expressed PD-L1 reached a plateau at 24 h, which were (46.26±10.71)% with LPS and (43.67±6.14)% with PWM stimulation, respectively. No markedly change of PD-L1 expression on the surface of the activated T cells after stimulation with LPS was observed, but upregulation of PD-L1 expression was observed when stimulation with PWM.
