BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective:To evaluate the effect of combining contralateral high-frequency transcranial magnetic stimulation (rTMS) with biofeedback-controlled empty swallowing training on dysphagia among stroke survivors.Methods:Eighty dysphagic stroke survivors were divided at random into a control group, a biofeedback group, an rTMS group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the biofeedback group and the rTMS group received empty swallowing training based on biofeedback or high-frequency rTMS applied to the healthy motor cortex as appropriate. The combined treatment group was given both. The treatment was administered once daily, 5 days a week for 3 consecutive weeks. Before and after the treatment, all of the subjects′ swallowing was evaluated using the penetration aspiration scale (PAS), functional oral intake scale (FOIS) and a standardized swallowing assessment (SSA). The latency and amplitude of the mylohyoid muscle′s motor evoked potentials (MEPs) were also recorded before and after the treatment.Results:After the treatment, significant improvement was observed in the average PAS, FOIS and SSA scores as well as in the latency and amplitude of the MEPs in the four groups. The average results in the combined treatment group were significantly better than in the other 3 groups. The latency of the mylohyoid muscle′s MEP was significantly shorter in the combined group than in the control and biofeedback groups on average, while the amplitude was significantly greater than in the control group.Conclusion:Combining contralateral high frequency rTMS with empty swallowing training based on biofeedback can better improve the swallowing of dysphagic stroke survivors.

ObjectiveTo establish a qualitative analysis method for the chemical constituents of the reference sample of Xiao Xumingtang， and to establish the fingerprint of 15 batches of Xiao Xumingtang， so as to evaluate the quality consistency among batches. MethodAccording to the key information of Xiao Xumingtang in the Key Information Table of Ancient Famous Classical Formulas（25 Formulas）， the reference sample of this formula was prepared， and it was detected by ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）. The chemical components were identified by self-constructed database， consulting relevant literature， and comparing with the reference substances， and the components were assigned by comparing with single drug samples and negative samples lacking single drug. The fingerprint of the reference sample of Xiao Xumingtang was established using high performance liquid chromatography（HPLC）， and the common peaks were assigned and identified through single drug samples and negative samples lacking single drug. ResultBased on the information of MS fragments， relevant literature， and database retrieval， a total of 64 compounds were identified and inferred from the reference sample of Xiao Xumingtang， including 31 flavonoids， 8 terpenoids， 12 triterpenoid saponins， 2 phthalides， 3 phenylpropanoids， 2 gingerols， 5 alkaloids， and 1 cyanoside. Among them， 21 were derived from Scutellariae Radix， 10 from stir-fried Glycyrrhizae Radix et Rhizoma， 9 from Ginseng Radix et Rhizoma， 8 from Paeoniae Radix Alba， 4 from Saposhnikoviae Radix， 3 from Stephaniae Tetrandrae Radix， 3 from Chuanxiong Rhizoma， 2 from Aconiti Lateralis Radix Praeparata， 2 from Zingiberis Rhizoma Recens， 1 from Ephedrae Herba， and 1 from Armeniacae Semen Amarum. The established HPLC fingerprint of the reference sample of Xiao Xumingtang had 23 common peaks， among which， peaks 1 and 2 were derived from Paeoniae Radix Alba， peaks 3 and 7 from Saposhnikoviae Radix， peaks 4， 8 and 9 from Stephaniae Tetrandrae Radix， peaks 10， 17， 18， 20 and 21 from stir-fried Glycyrrhizae Radix et Rhizoma， peaks 11-16， 19 and 22 from Scutellariae Radix， peak 5 from Chuanxiong Rhizoma， peak 23 from Zingiberis Rhizoma Recens， peak 6 was the common component of stir-fried Glycyrrhizae Radix et Rhizoma and Scutellariae Radix.

Objective:To seek any differential effect of combining repeated transcranial magnetic stimulation (rTMS) with a modified version of constraint-induced movement therapy (mCIMT) on the walking ability of stroke survivors.Methods:Seventy-five stroke survivors were randomly divided into a sham rTMS group, an rTMS group and a combined group, each of 25. In addition to 40 minutes of routine rehabilitation daily, including balance training, transfer training, muscle strength training, and proprioceptive training five times a week for 4 weeks, the sham rTMS group and rTMS group received sham or genuine rTMS. The combined group received 20 minutes of rTMS followed by mCIMT training 30 minutes later. The treatment was performed once a day, 5 days a week for 4 weeks. Before and after the treatment, all groups were evaluated using the Fugl-Meyer lower extremity assessment, the Berg balance scale, a 10-metre walk test and the modified Barthel index.Results:Significant improvement was observed in the average scores of all three groups in all of the assessments. The combined group′s averages were, however, significantly better than those of the other two groups.Conclusion:Supplementing mCIMT with rTMS can better improve the walking and other abilities in the activities of daily living of stroke survivors.

Objective To analyze the correlation between the single nucleotide polymorphisms (SNPs) in the promoter of Piwil1 gene and gastric cancer. Methods The expression of Piwil1 mRNA in the tumor tissues of 3 patients with gastric cancer was detected by RT-qPCR, and RNA-Sequencing data from the Cancer RNA-Seq Nexus were analyzed for Piwil1 mRNA expression in gastric patients. Blood samples were collected from 24 gastric cancer patients and 29 healthy control subjects for PCR amplification of Piwil1 gene promoter region. The SNP loci in the promoter region of Piwil1 gene were determined by direct sequencing, and the results were analyzed by SnapGene software. Results Analysis of the data from Cancer RNA-Seq Nexus and the results of RT-qPCR in 3 gastric cancer patients all showed significantly increased Piwil1 expression in gastric cancer tissues compared with the adjacent tissues. Seven SNP loci in two CpG regions of the Piwil1 gene promoter were genotyped, and only one SNP locus was found to be related to gastric cancer. The frequencies of GG, GA, and AA genotypes at the rs28416520 locus in CpG 67 region were 79.2％, 16.7％, and 4.1％in the gastric cancer group, and were 37.9％, 55.2％, and 6.9％in the control group, respectively, showing a significantly higher frequency of the GG genotype in gastric cancer group (OR=0.144, 95％CI:0.045-0.564,χ2=9.071, P＜0.01). The frequency of allele G of the rs28416520 locus was significantly higher in gastric cancer group than in the control group (87.5％vs 65.5％;OR=0.271, 95％CI:0.099-0.766,χ2=6.856, P＜0.01). The genotype or allele frequencies of the other 6 SNPs locus did not differ significantly between gastric cancer group and control group. Conclusions The expression of Piwil1 is increased in gastric cancer tissues as compared with the adjacent tissues. The GG genotype and G allele of rs28416520 within CpG 67 region are associated with an increased risk of gastric cancer.
