Methods Medullary slices of newborn Sprague-Dawley rats were prepared for the experiment. The electrophysiological experiment comprised 5 groups (each with 8 slices), each of which were perfused with artificial cerebrospinal fluid, CO, 1H-[1, 2, 4] oxadiazolo [4, 3-a] quinoxalin-1-one (a specific inhibitor of sGC, ODQ group), ODQ+CO (ODQ+CO group), and dimethyl sulfoxide, respectively. The burst frequency of hypoglossal rootlets was recorded as an index of rhythmic respiratory activity. Radioimmunoassay was employed to determine cGMP levels of the medullary slices of the ACSF control group, exogenous CO group, ODQ group and ODQ+CO group (n=6/group).

The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin in liver tissues of all mice.

The results showed that, on code evaluation performance, the effect of self-explanation was not significant between groups, but high prior knowledge learners outperformed low prior knowledge learners. On code generation performance, the guiding-question group outperformed the principle- prompt group and the control group. And the high prior knowledge group scored significantly higher than the low prior knowledge group. Finally, on the analysis of attitudes toward self-explanation activities, the guiding-question group showed more positive acceptance than the principle-prompt group.

Therefore, the multi-stage interaction structures with losses and severed structure were more stability for absolute instability and gyrotron backward oscillations. This study presents a nonlinear analysis of typical oscillations, including absolute instability, gyrotron backward oscillation and reflective oscillation. The multi-stage gyro-TWT seem to increase effectively the start-oscillation currents of the absolute instability, gyro-BWO, and reflection oscillation.
