ABSTRACT
Objective:To explore the expression of the nucleotide-binding oligomerization domain-like receptor containing pyrin domain protein 6 (NLR family,pyrin domain containing 6,NLRP6) in the gastric tissue and gastric juice of children with chronic non-atrophic gastritis (CNG), and to analyze the influence of Helicobacter pylori (Hp) infection on the expression of NLRP6.Methods:A case-control study was conducted to select 120 CNG patients in pediatrics of Department of Pediatrics, The Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021. According to pathological diagnosis, endoscopic gastric mucosal damage and Hp infection, they were divided into 4 groups: mild CNG group Hp negative, Moderate to severe CNG group Hp negative, Mild CNG group Hp positive, Moderate to severe CNG group Hp positive. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of NLRP6 in the four groups of gastric tissue and gastric juice, and Western blot was used to detect the expression of NLRP6 in the gastric tissue of the 4 groups, and the significance of expression in CNG of children is analyzed. Independent sample t-test was used to compare the mean between the two groups. One way ANOVA was used to compare the mean of multiple groups of samples, and LSD t-test was used for pairwise comparison. Comparison between count data groups χ 2 inspection. Results:The positive rate of Hp in the moderate to severe chronic non-atrophic gastritis group was 62.96% (34/54) higher than that in the mild chronic non-atrophic gastritis group 37.04% (20/54), and the difference was statistically significant (χ 2=18.32, P<0.001). Under the same Hp conditions, the expression of NLRP6 in the mild chronic non-atrophic gastritis group (Hp negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp positive mild CNG: Gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L was higher than the moderate to severe chronic non-atrophic gastritis group (Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L; Hp positive Moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under Hp negative, mild compared with moderate to severe CNG: gastric tissue P=0.035; gastric juice P=0.046; Under Hp positive, mild compared with moderate to severe CNG: gastric tissue P=0.010;gastric juice P=0.002); in the same degree of gastric mucosal injury, NLRP6 expression in Hp-negative group (Hp-negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L higher than the positive group (Hp positive mild CNG: gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L; Hp positive moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under mild CNG, Hp negative is compared with positive: Gastric tissue P=0.005; gastric juice P=0.023; under moderate to severe CNG, negative versus positive: gastric tissue P=0.004; gastric juice P=0.003). Conclusion:Under the same Hp conditions, the more severe the gastric mucosal damage, the lower the NLRP6; under the same degree of mucosal damage, the expression level of NLRP6 in the Hp-negative group was significantly higher than that of the Hp-positive group. It is suggested that NLRP6 plays a role in inhibiting inflammation in chronic gastritis, maintaining the integrity of epithelial cells, and Hp can inhibit the expression of NLRP6.

ABSTRACT
Objective: Harmonization method is one of the eight unique methods of traditional Chinese medicine with important application value in clinic. Based on the effect of harmonization method in regulating cold and heat, the mechanism of Huangliantang in treating chronic non-atrophic gastritis(CNAG) on rats were studied. Method: Rats were divided into normal group (n=10) and CNAG model group (n=50). The model of CNAG rats was induced by chemical stimulation combined with hunger and satiety. The model group was randomly divided into 5 groups, namely the model group, the Jinghua Weikang pill treatment group, and the high, middle and low-dose Huangliantang groups, with 8 rats in each group. After the model was successfully established, the Jinghua Weikang pill treatment group (0.04 g·kg-1), the high, middle, low dose Huangliantang group (11.00,5.48,2.74 g·kg-1), the blank group and the model group were given the same dose of saline for 4 weeks, and then the samples were collected. The histological changes of gastric mucosa were observed by hematoxylin-eosin (HE) staining. The serum levels of interleukin-6 (IL-6), interleukin-1β (IL-1β) and interleukin-8 (IL-8) were measured by enzyme-linked immunosorbent assay (ELISA). immunohistochemistry(IHC) was used to detect nuclear factor-κB (NF-κB) and its inhibitory protein receptor (IκBα), protein expression. Real-time quantitative fluorescence polymerase chain reaction (Real-time PCR) was used to detect IκBα, NF-κB mRNA expressions. Result: In the model group, the gastric mucosa was damaged, a large number of inflammatory cells were infiltrated, the serum inflammatory factors increased significantly, mRNA and protein expressions of IκBα decreased, and mRNA and protein expressions of NF-κB increased in the gastric tissue (PκBα was up-regulated, IκBα protein was increased, while the expression of NF-κB mRNA was down-regulated, and NF-κB protein was decreased. The Jinghua Weikang pill treatment group and the high-dose Huangliantang group had the most obvious improvement (PPConclusion: Huangliantang for regulating cold and heat based on the harmonization method can effectively alleviate the degree of gastric mucosal injury, and reduce serum inflammatory factors in CNAG rats. The mechanism is related to the up-regulation of IκBα mRNA expression, and the down-regulation of NF-κB mRNA expression and NF-κB protein expression in gastric mucosa.
ABSTRACT
OBJECTIVE: To compare the distribution regularity of the pressure-sensitive acupoints in patients with chronic non-atrophic gastritis (CNAG) and healthy subjects, so as to provide suitable acupoint combinations for clinical treatment. METHODS: A total of 120 volunteer subjects including 60 CNAG patients (29 men and 31 women, (40.7±10.3) years at the average age) and 60 healthy subjects (28 men and 32 women, and (40.8±10.2) years at the average age) were enrolled in the present study. The pressure-sensitive acupoints were checked by a fixed operator using his finger pulp along the body trunk and the four limbs and marked on a prepared human dermatome graph. The number of pressing sensitive acupoints were counted, and the relationship between the distribution of the detected sensitive acupoints and the position of meridians and nerve segments was analyzed. RESULTS: The incidence of pressure-sensitive acupoint in CNAG patients and healthy subjects were 86.7% and 15.0%, respectively. In 60 CNAG patients, the most frequently met sensitive acupoints were Xuehai (SP10), Zhongwan (CV13), and Zhongting (CV17) in sequence, mainly covering the Conception Vessel, Spleen Meridian of Foot-Taiyin (SP), and the Stomach Meridian of Foot-Yangming (ST). The sensitive acupoints presented a nerve-segmental distribution within T7-T10 and L3-L5. CONCLUSION: The pressure-sensitive acupoints present a nerve-segmental distribution and have a higher corresponding rate with some meridians related to the stomach, especially under diseased conditions.
ABSTRACT
Objective To observe the clinical effect of Danggui Sini decoction for treatment of patients with chronic non-atrophic gastritis and spleen-stomach deficiency cold syndrome.Methods A prospective randomized control trial was conducted, including 126 in- and out-patients with chronic non-atrophic gastritis diagnosed by gastroscopy and spleen-stomach deficiency cold syndrome differentiated by traditional Chinese medicine (TCM) method admitted to Chinese Medicine Hospital of Haikou City. They were randomly assigned to an observation group (65 cases) and a control group (61 cases).

ABSTRACT
Objective To investigate the effect of rebamipide on chronic non-atrophic gastritis (NAG) with erosion and its protection of gastric mucosa from Helicobacter priori(Hp) associated lesions.Methods Patients(n=452)with endoscopically confirmed NAG with erosion from 11 hospitals in China were enrolled and randomly assigned at a ratio of 3:1 to receive either rebamipide(100 mg t.i.d.)or sucralfate(1.0 t.i.d.)for 8 weeks.Hp infected patients received eradication treatment before randomization.Symptoms,endoscopic scores and histological changes were recorded before and after therapy.Concentrations of serum prostaglandin E(PGE:)and oxygen free radical(MDA)were measured in patients from 2 centers.Results Per-protocol analysis(n=415)showed that the dyspeptic symptom score in rebamipide group decreased significantly after eight weeks of treatment. The endoscopic inflammation score in rebamipide group also decreased from 2.65 ±0.09 to 0.60±0.10(P<0.001),which was,significantly better than that of sucralfate group(P<0.001).Histological findings were consistent with the endoscopic findings.There Was a significant elevation(P=0.002)in PGE2 concentration in mucesa from rebamipide-treated subjects [(225.4±18.3) pg/g vs.(266.7±14.7)Pg/g] compared with that in sucralfate group.The concentration of MDA significantly decreased from(325.9±65.6)mmoL/g to(216.5±61.5)mmol/g,which is markedly different from that of sucralfate group(P=0.046).No statistical difference was found between Hp eradication group,Hp infection group and Hp negative group,regarding the effect of Rebamipide.Conclusion Compared to sucralfate,Rebamipide demonstrates a superior effect on improvement of dyspepsia symptom and endoscopic findings in erosive NAG,which is not influenced by Hp infection.
