[Acupuncture based on meridian diagnosis for chronic atrophic gastritis]

To compare the efficacy between acupoint selection of meridian diagnosis and regular acupoint selection for chronic atrophic gastritis (CAG).

A total of 70 cases of CAG were randomly divided into an observation group (35 cases, 5 cases dropped off) and a control group (35 cases, 5 dropped off). In the observation group, according to the hand diagnosis of meridians and the results of 80-channels energy determinator, based on the principle of child-mother relation acupoint combination, the luo-connecting point and back-shu points were added for excess syndrome, and the yuan-primary point, front-mu points and he-sea point of foot meridians were added for deficiency syndrome; in addition, the acupoints of the eight extraordinary meridians were added based on the nature of acupoints. In the control group, Zhongwan (CV 12), Neiguan (PC 6), Zusanli (ST 36) and Gongsun (SP 4) were selected as the primary acupoints, and additional acupoints were added according to syndrome differentiation. The two groups were treated twice a week (Tuesday and Thursday, respectively), totally for 6 months. Six months after treatment, the follow-up was conducted. The clinical symptom score, gastroenteropathy patient reported outcomes (PRO) scale score before treatment, after treatment and during follow-up as well as the score of pathological changes of gastric mucosa before and after treatment were compared between the two groups.

After treatment and during follow-up, the clinical symptom scores and gastroenteropathy PRO scale scores were decreased in the two groups (P<0.01, P<0.001); at the follow-up, the gastroenteropathy PRO scale score in the observation group was lower than that in the control group (P<0.01). After treatment, the scores of pathological changes of gastric mucosa in the two groups were decreased (P<0.01), and the score in the observation group was lower than that in the control group (P<0.05).

The acupoint selection of meridian diagnosis is superior to regular acupoint selection for CAG, which has better efficacy, more significant improvement on gastric mucosa pathology, and more stable long-term effect.
