Background:Increasing Helicobacter pylori resistance has led to decreases in treatment effectiveness.Aim: To test the effectiveness of susceptibility-guided therapy vs a locally highly effective empiric modified bismuth quadruple therapy for first-line H pylori treatment in a region with high antimicrobial resistance. Methods:We compared 14-day susceptibility-guided with empiric therapy using a multicentre superiority-design trial, which randomised H pylori infected subjects 3:1 to (a) susceptibility-guided therapies contained esomeprazole 20 mg and amoxicillin 1 g b.d. plus clarithromycin 500 mg, metronidazole 400 mg b.d., or levofloxacin 500 mg daily for susceptible infections or bismuth 220 mg b.d. and metronidazole 400 mg q.d.s. for triple-resistant infections; (b) Empiric therapy contained esomeprazole 20 mg, bismuth 220 mg b.d., amoxicillin 1 g and metronidazole 400 mg t.d.s.Primary outcome was H pylori eradication. Results: Between February 2017 and March 2018, 491 subjects were screened and 382 were randomised. Both the susceptibility-guided and the empiric regimens were highly successful with per-protocol eradication rates of 97.7% (250/256) vs 97.6% (81/83, P = 1.00) and intent-to-treat eradication rates of 91.6% (262/286) vs 85.4%(82/96, P = 0.12). Overall, susceptibility-guided therapy was not superior to empiric therapy with 0.1% per-protocol (95% CI −3.1% to 3.2%) and 6.2% intent-to-treat (−0.3% to 12.7%) eradication difference. Both approaches had high adherence and low adverse event rates.Conclusions: Both susceptibility-guided and empiric therapies provided excellent eradication rates. Clinically, the choice would hinge on availability of susceptibility testing and/or a locally highly effective empiric therapy.

Poor adherence to treatment instructions may play an important role in the failure of Helicobacter pylori eradication. The aim of this study was to evaluate the effects of telephone-based reeducation on 14-day quadruple H. pylori eradication therapy. In total, 162 patients were randomly assigned (1 : 1) to either the intervention group (patients received telephone-based reeducation on the 4th, 7th, and 10th days of the course) or the control group (patients received instructions only at the time of getting the prescriptions). All patients received a 14-day quadruple H. pylori eradication therapy. The primary outcome was the H. pylori eradication rate. The secondary outcomes included the symptom relief rates and the incidence rates of adverse events. Seventy-five patients in the reeducation group and 74 patients in the control group completed the follow-up. The H. pylori eradication rate in the reeducation group was statistically higher than that in the control group (intention-to-treat: 72.8% vs. 50.6%, P=0.006; per-protocol: 78.7% vs. 55.4%, P=0.003). However, the symptom relief rates and the adverse event rates in these two groups were not significantly different. Overall, the results from this study suggest that telephone-based reeducation can be potentially applied to improve the H. pylori eradication rate in clinical practice, without significantly increasing the adverse effects.
As the worldwide population ages, the prevalence of Alzheimer's disease (AD) increases. However, the results of promising medications have been unsatisfactory. Chinese acupuncture has a long history of treating dementia, but lack of evidence from well-designed randomized controlled trials that validate its efficacy and safety, as well as its lack of clear underlying mechanisms, contribute to its limited application in clinical practice. In recent years, brain imaging technologies, such as functional magnetic resonance imaging and positron emission tomography, have been used to assess brain responses to acupuncture in a dynamic, visual, and objective way. These techniques are frequently used to explore neurological mechanisms of responses to acupuncture in AD and provide neuroimaging evidence as well as starting points to elucidate the possible mechanisms. This review summarizes the existing brain imaging evidence that explains the effects of acupuncture for AD and analyzes brain responses to acupuncture at cognitive-related acupoints [Baihui (GV 20), Shenmen (HT 7), Zusanli (ST 36), Neiguan (PC 6), and Taixi (KI 3)] from perspectives of acupoint specificity and acupoint combinations. Key issues and directions to consider in future studies are also put forward. This review should deepen our understanding of how brain imaging studies can be used to explore the underlying mechanisms of acupuncture in AD.
To date, a growing number of clinical studies have demonstrated the safety and health benefits from Baduanjin intervention. Based on this, our objective is to systematically retrieve and summarize the clinical studies on Baduanjin, with a view to providing more evidence-based evidence in support of the application of Baduanjin for healthcare, and to identify the shortcomings of existing research and provide feasibility suggest for further clinical research. Both four English language and four Chinese language electronic databases were used to search articles related to Baduanjin during 2000–2019. SPSS 22.0 software was used to analyze the data, and the risk of bias tool in the RevMan 5.3.5 software was used to evaluate the methodological quality of randomized controlled trials. A total of 810 publications were identified, including 43 (5.3%) systematic reviews, 614 (75.8%) randomized controlled trials, 66 (8.1%) nonrandomized controlled clinical studies, 84 (10.4%) case series, and 3 (0.4%) case reports. The top 10 diseases/conditions included diabetes, chronic obstructive pulmonary disease, hypertension, low back pain, neck pain, stroke, coronary heart disease, cognitive impairment, insomnia, and osteoporosis or osteopenia. The style of State General Administration of Sport of China in 2003 was the most commonly used version of Baduanjin, and Baduanjin was practiced with an average of 35 minutes, 1 or 2 times a day, 3–5 days per week, and a 18-week average duration. It is also worth noting that there were no serious adverse events related to Baduanjin intervention. Most studies were small sample size research, and the methodological quality of randomized controlled trials is generally low. The clinical studies of Baduanjin have a substantial quantity and evidence base. However, there are significant differences among different studies in the specific intervention measures such as style, intensity, duration, learning, and practice methods, which need to be further standardized and unified. Further high-quality designed and reporting studies are recommended to further validate the clinical benefits of Baduanjin.
