The intervention group C patients were given electronic moxibustion therapy based on the theory of Ziwen Liuzhun (midnight to dawn) under the premise of the control group B. According to the theory of Ziwen Liuzhun, the hour of Ba (05:00 - 07:00) is the time when the large intestine meridian is in charge, and at this time, the blood and qi of the large intestine are abundant, which is most conducive to excretion. The hour of Chen (07:00 - 09:00) is the time when the stomach meridian is in charge, and at this time, the qi of the stomach meridian is vigorous, which is most conducive to regulating the connection between the stomach and the spleen. Based on the specific conditions of each patient, moxibustion treatment was given at the corresponding hour. The specific moxibustion therapy was the same as that of the control group. The intervention lasted for 2 weeks.
