METHODS: Twelve different H pylori strains were chosen to amplify the 710-bp segments of gene hpaA. These strains were NCTC11637, SS1; Chongqing clinical isolates CCS9801, CCS9802, CCS9803, CCS9806, CCS9809, CCS9810, CCS9813, which were gained from patients of gastritis; Mongolia gerbil adapted H pylori strains (abbreviation MG), which were gained from the following steps: gastric mucosal specimens of Mongolia gerbils infected by clinical isolate CCS9803 were cultured and detected, the positive H pylori strains were named as the first generation of Mongolia gerbil adapted H pylori strains (abbreviation MG1) and then were subcultured with healthy Mongolia gerbil to generate MG2, in turn to gain the ninth generation (abbreviation MG9). All hpaA segments, obtained from 12 different H pylori strains, were digested by Hhal and HaeIll individually and analyzed by agarose gel electrophoresis. RESULTS: In all 12 strains, the 710-bp PCR products were successfully amplified and products were cloned to pMD18-T vector respectively, then the recombinant plasmids were digested simultaneously with Ncol and Xhol to recover the small fragments. The objective fragments from 12 different H pylori strains digested with Haelll could be seen as 4 types of bands and 5 types with Hha I. According to the hpaA RFLP patterns, the 12 H pylori strains could be divided into 5 groups: group I, NCTC11637 and SS1; group II, CCS9809, which RFLP type digested with HaeIll was the same as strains of group I, but Hhal RFLP showed difference compared with the other groups; group III, CCS9810; group IV, CCS9803; group V: CCS9801, CCS9802, CCS9806, CCS9813, MGl, MG3 and MG9. The sequence data of 12 hpaA segments were analyzed by DNAsis software and it was observed that: (1) The homologies of base pair and amino acid sequence between strains NCTC11637, SS1, CCS9809 were 99.6% and 98.9%, respectively; (2) The homology of base pair and amino acid sequence between CCS9803 and CCS9810 was 97.7% and 99.1%; (3) That of the rest strains, CCS9801, CCS9802, CCS9806, CCS9813, MGl, MG3, MG9 reached 99.4% and 98.4%; (4) The base pair homologies between all hpaA fragments of different sources were higher than 94.6%, therefore the correspondence of deduced amino acid sequence was higher than 96.8% between each other. CONCLUSION: The gene hpaA from different H pylori strains revealed variation, and this might provide an effective method for molecular epidemiological survey of H pylori.展开更多

METHODS: Eighty-two patients with H. pylori-related gastritis treated in our hospital from January 2016 to December 2017 were selected according to the random number table method and divided into experimental group and control group, with 41 patients in each group. The control group was treated with standard triple therapy, while the experimental group was additionally treated with modified Chaihu Guizhi Ganjiang Decoction. The venous blood of one elbow was taken before and after treatment. The concentrations of serum CagA and Hp-NAP were detected by enzyme-linked immunosorbent assay(ELISA). The symptoms were evaluated according to the change of symptom scores before and after the intervention. The H.pylori eradication rate was calculated. RESULTS: There was no significant difference in CagA and Hp-NAP concentrations between the 2 groups before intervention(P > 0.05). After intervention, CagA and Hp-NAP concentrations in experimental group were(19.21±6.27) ng/L and(24.37±6.10) ng/L respectively which were lower than(25.81±7.14) ng/L and(32.09±5.73) ng/L of control group. The differences were statistically significant(P < 0.05). The total effective rate of major symptoms in experimental group was 39 cases(95.12%), which was significantly higher than that of the control group(31 cases, 75.61%). There was statistically significant difference between the 2 groups(P < 0.05). The eradication rate of H.pylori was 38 cases(92.68%) in the experimental group, which was significantly higher than 31 cases(75.61%) of the control group. The difference between the 2 groups was statistically significant(P < 0.05). CONCLUSION: Chaihu Guizhi Ganjiang Decoction combined with standard triple therapy can effectively reduce CagA, Hp-NAP of serum level in patients with H.pylori-related gastritis, improve efficacy of symptoms and eradication rate of H.pylori, and is worthy of clinical promotion.展开更多
