Background:Gastroesophageal reflux disease(GERD)is a common disorder of digestive system,however,some of patients are not responding to conventional 4-8 weeks proton pump inhibitor therapy. Aims:To investigate the effect of digital music gastric electrical pacing on clinical symptoms,anxiety and depression and esophageal motility in patients with refractory GERD. Methods:Fifty-three patients with refractory GERD from Jan. 2014 to Oct. 2015 at the Third Affiliated Hospital,the Third Military Medical University were recruited. All of them fulfilled the Montreal definition of GERD. Digital music gastric electrical pacing was performed for 15 days and the efficacy was evaluated by clinical symptom scoring,Hamilton anxiety scale( HAMA),Hamilton depression scale( HAMD)and esophageal motility manometry. Results:After 15-day treatment,the main symptoms,including heartburn,daytime and nocturnal acid reflux,upper abdominal pain,nausea,and sleep disorder were significantly improved(P < 0. 001). A great proportion of patients were complicated with anxiety and/ or depression at recruitment,and after treatment the scores of HAMA and HAMD were decreased significantly(P < 0. 001). Meanwhile,the lower esophageal sphincter resting pressure(LESP),distal wave amplitude,peristaltic wave duration,speed of peristaltic wave and distal contraction integral after treatment were significantly increased as compared with the baseline values(P < 0. 05). Conclusions:Digital music gastric electrical pacing is effective for treatment of refractory GERD with increase of LESP and esophageal body motility. The clinical symptoms and anxiety and depression are improved simultaneously. Digital music gastric electrical pacing is expected to be a new choice of non-medicine treatment for esophageal motility disorders.

Gastric ''inflammation-cancer'' transformation stars from inflammation and ends as gastric cancer (GC), and the pathogenesis is still unclear. In China, GC features high morbidity and mortality and poor prognosis, influencing the quality of life and physical and mental health of patients. Therefore, it is of great significance to construct the prevention and treatment system for GC. Chronic atrophic gastritis (CAG) plays a key role in the occurrence, development, and outcome of gastric ''inflammation-cancer'' transformation. Modern therapies for CAG generally aim at eliminating causes and alleviating clinical symptoms, which show satisfactory short-term efficacy, but the reverse and recurrence are common. Based on the holistic view, syndrome differentiation-based treatment, and the ''inflammation-cancer'' transformation in modern medicine, traditional Chinese medicine emphasizes both prevention and treatment, with individualized therapies for CAG and GC to control the transformation. According to the pathogenesis of CAG-asthenia in origin and sthenia in superficiality and deficiency-excess in complexity, this study proposed the theory of spleen deficiency and pathogen stagnation in CAG, and believed spleen deficiency, pathogen, and stagnation are respectively the root cause of, the main factor of, and the key to ''inflammation-cancer'' transformation, respectively. Spleen deficiency and pathogen stagnation are closely related to the process of the transformation. For the treatment, the spleen-invigorating and pathogen-eliminating method should be used for invigorating the spleen to consolidate original Qi, improve the blood supply in stomach, and regulate immunity, and eliminating the pathogen to relieve stagnation, reduce the occurrence of non-controllable inflammation, and improve inflammatory micro-environment. As a result, the gastric inflammation is controlled at the early stage and the gastric ''inflammation-cancer'' transformation is blocked. The gastric mucosal lesions are blocked, delayed, or even reversed. This study provides a new idea in clinical diagnosis and treatment of CAG and in the prevention of GC.

ObjectiveTo explore the effect of Weiwei Tongtiao decoction (WTD) on chronic atrophic gastritis (CAG) rats and the underlying mechanism. MethodA total of 90 SD rats were randomized into normal control group, model group, high-dose, medium-dose, and low-dose WTD groups (18, 9, 4.5 g·kg-1·d-1 WTD, respectively, ig), and weifuchun control group (0.45 g·kg-1·d-1 weifuchun aqueous solution, ig), with 15 rats in each group. The N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) was employed to induced CAG in rats. After the modeling (identified by histopathological examination), the administration began and lasted 12 weeks. Then, gastric mucosa tissues of the rats were collected and stained with hematoxylin and eosin (HE), and the pathological changes of gastric mucosa were observed under the optical microscope. Real-time PCR, immunohistochemistry (IHC), and Western blotting were applied to examine the mRNA and protein expression of indexes in nuclear factor kappa-B (NF-κB) signaling pathway in the gastric mucosa of rats. ResultCAG rats showed irregular arrangement and morphology of the inherent glands in gastric mucosa and the glands decreased or disappeared. In addition, inflammatory cell infiltration was observed in the lamina propria of CAG rats, and about 48.4% presented intestinal metaplasia. WTD significantly alleviated the reduction of the glands and intestinal metaplasia in a dose-dependent manner. Compared with the normal control group, the model group demonstrated increase in the mRNA expression of cyclooxygenase-2 (COX-2), NF-κB p65, interleukin (IL)-1α, IL-1β, IL-10, IL-8α, and IL-8β, and protein expression of COX-2, NF-κB p65, and IL-10 (P<0.01). WTD and weifuchun lowered the mRNA expression of COX-2, NF-κB p65, IL-1α, IL-1β, IL-10, IL-8α, and IL-8β, and the protein expression of COX-2, NF-κB p65, and IL-10 in gastric mucosa of CAG rats (P<0.01). The expression of the above indexes after the intervention with high-dose WTD was close to that of the normal control group. ConclusionWTD can improve or even reverse the diseased gastric mucosa of CAG rats, and the mechanism is the likelihood that WTD down-regulates the mRNA and protein expression of the indexes in NF-κB signaling pathway in gastric mucosa of CAG rats.
