[Abstract]:Objective: To establish a chronic fatigue rat model and observe the effects of Guilu Yishen Formula Granules on the general condition and behavioral indexes (exhaustive swimming time, resting time of rat tail suspension) of chronic fatigue rats. To explore the pathogenesis of chronic fatigue syndrome, observe the effect of Guilu Yishen Formula Granule on the microstructure of skeletal muscle mitochondria and serum SDH in rats with chronic fatigue, and explore its mechanism of action, so as to provide experimental basis and theoretical support for the clinical application of Guilu Yishen Formula Granule in treating CFS.
METHODS: Forty male SPF SD rats weighing 200 65 The control group was randomly divided into three groups: model group, Cistanche deserticola Yishen group and Guilu Yishen group. On the basis of normal feeding, normal group was given normal saline by gastric lavage; normal control group, Guilu Yishen formula suspension was given by gastric lavage; Cistanche deserticola Yishen group was given Cistanche deserticola Yishen formula suspension. The rats in each group were given the suspension once a day for 14 consecutive days. The body weight, exhaustive swimming time and tail suspension rest time were measured before modeling, after modeling and after the last administration. The supernatant of abdominal aorta was collected and the SDH activity was determined by ELISA. The data were processed by IBM SPSS 19.0 statistical software.
Results: (1) After modeling, the body weight of rats in each group increased slowly or even decreased, diet, water intake decreased, squint lazy, stool, hair dull loss of luster. Compared with the normal group, there was no significant difference in body weight, exhaustive swimming time, tail suspension rest time (P 0.05); model group, Guilu Yishen group, cirong Yishen group There were significant differences in weight loss, exhaustive swimming time and tail suspension rest time between the two groups (P 0.05). There were significant differences in weight loss (P 0.05), exhaustive swimming time and tail suspension rest time (P 0.05), body weight loss, exhaustive swimming time shortened and tail suspension rest time prolonged in model group (P 0.05). The weight of rats in Yishen group was significantly increased, the time of exhaustive swimming was significantly prolonged, and the rest time of tail suspension was significantly shortened (P 0.05).
(2) The myofibrils of skeletal muscle in model group were arranged disorderly, Z-line, M-line were blurred and arranged disorderly, the shape of mitochondria was irregular, and the volume of mitochondria was smaller than that of normal group. Most of mitochondria were vacuole, membrane dissolved and connected with each other. Compared with the normal group, the skeletal muscles of the normal control group were arranged more orderly, Z-line and M-line were clear and arranged more regularly, and the mitochondrial structure was more complete and larger.
(3) Compared with the normal group, the serum SDH activity of the normal control group decreased significantly (P 0.05); the serum SDH activity of the Guilu Yishen group increased slightly (P 0.05); the serum SDH activity of the Cistanche Yishen group increased significantly (P 0.05). Compared with the model group, the serum SDH activity of the Cistanche Yishen group and the Guilu Yishen group increased slightly (P 0.05). The activity of serum SDH in Guilu Yishen group was significantly lower than that in Cistanche deserticola Yishen group (P 0.05).
CONCLUSIONS: (1) A rat model of chronic fatigue was established by means of non-viral chronic stress stimulation, i.e. forced exhaustive swimming, restraint and tail-clip irritation. This method can simulate the internal and external environment of human fatigue and replicate the chronic fatigue state of human body.
(2) Guilu Yishen Formula Granule can prolong the exhaustive swimming time of rats with chronic fatigue, shorten the resting time of rat tail suspension, protect the integrity of the three-dimensional structure of the line, and reduce the activity of serum SDH.
(3) The results showed that the structure of skeletal muscle and its mitochondria was easy to be damaged, and it was not easy to recover, and the activity of serum SDH was obviously increased. Guilu Yishen formula granule could enhance the stability of skeletal muscle and its mitochondrial membrane, promote the recovery of injury, enhance the function of mitochondria and reduce the activity of serum SDH. The mechanism of chronic fatigue syndrome and the mechanism of Guilu Yishen Formula Granule in treating chronic fatigue syndrome were further elucidated, which provided experimental basis for clinical application of Guilu Yishen Formula Granule in treating chronic fatigue syndrome.
(4) Gui Lu Yi Shen formula granule can be used as a preventive drug for CFS.
