OBJECTIVE: To investigate the mechanism of Ping-wei capsules(PWC) in improving gastrointestinal m otility in rats with functional dyspepsia(FD).METHODS: We established an FD model by stimu-lating semi-starvation rats via tail damping, provo-cation, and forced exercise fatigue. The FD model group was further divided into five groups accord-ing to the treatment received: normal saline, dom-peridone, low-dose PWC, mid-dose PWC, or highdose PWC. The effect of PWC on FD was evaluated by measuring gastrointestinal motility. Changes in leptin and cholecystokinin(CCK) were detected through enzyme-linked immunosorbent assay, re-verse transcription-polymerase chain reaction, and immunohistochemistry.RESULTS: PWC significantly increased gastrointesti-nal m otility in FD rats. Furthermore, PWC signifi-cantly increased CCK m RNA and protein concentra-tions in the duodenum and antrum, decreased leptin protein concentrations in the duodenum, an-trum, and hypothalamus, and decreased CCK pro-tein concentration in the hypothalamus.CONCLUSION: PWC improves gastrointestinal mo-tor function in FD rats by decreasing the leptin con-centration in serum and the brain-gut axis, and by increasing the CCK concentration in gastrointesti-nal tissue. Our findings help to elucidate the mech-anism of FD and provide further insight into the pharmacokinetics of PWC.

CONCLUSION： PWC improves gastrointestinal motor function in FD rats by decreasing the leptin concentration in serum and the brain-gut axis, and by increasing the CCK concentration in gastrointestinal tissue. Our findings help to elucidate the mechanism of FD and provide further insight into the pharmacokinetics of PWC.
