Background: Cerebral palsy (CP) is a common disability in children featured with pathological gait and limb function limitation due to muscle weakness. Improving limb function and quality of life is currently considered to be highlighted. Physiotherapy is a chief component of rehabilitation for children with CP, correcting gait and improve walking capacity through muscle strength training. Standard rehabilitation programs for CP have not been determined. Core stability training (CST), which coordinates limb balance via trunk control, is widely used in sports competition. And it is gradually introduced into the rehabilitation of children with cerebral palsy with a positive impact on the patients’ gait performance. By screening published literatures, this study aims to conduct a meta-analysis to systematically evaluate the effectiveness and safety of CST in gait of children with CP. Methods: Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on CST in the treatment of children with CP were searched from 6 databases. Moreover, the reference lists of conference papers and included literatures will be manually searched to avoid omissions. Literature screening and data extraction were performed independently by 2 researchers. RCTs carry out the risk of bias analysis evaluation from seven aspects through the Cochrane Collaboration's risk of bias tool. Fixed or random effect model will be performed to analyze the outcomes. When higher heterogeneity occurs (I 2 > 50%), the sensitivity or subgroup analysis will also be conducted to find potential factors. And the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach is used for assessing the quality of evidence. Results: The study will evaluate the effect of CST on gait of children with CP from multiple outcomes, including walking speed, endurance, stride length, and safety. Conclusion: Based on evidence-based medicine, the conclusion of this study can demonstrate the effectiveness and safety of CST in gait correction for children with CP.

Background: Artificial intelligence (AI) is used to solve the problem of missed diagnosis of polyps in colonoscopy, which has been proved to improve the detection rate of adenomas. The aim of this review was to evaluate the diagnostic performance of AI-assisted detection and classification of polyps in colonoscopy. Methods:The literature search was undertaken on 4 electronic databases (PubMed, Web of Science, Embase, and Cochrane Library). The inclusion criteria were as follows: studies reporting AI-assisted detection and classification of polyps; studies containing patients, images, or videos receiving AI-assisted diagnosis; studies which included AI-assisted diagnosis and reported classification based on histopathology; and studies providing accurate diagnostic data. Non-English language studies, case-reports, reviews, meeting abstracts and so on were excluded. The Quality Assessment of Diagnostic Accuracy Studies-2 scale was used to evaluate the quality of literature and the Stata 13.0 software was used to perform meta-analysis.Results: Twenty-six articles were included with all of medium quality. Meta-analysis showed none of literature had any obvious publication bias. The application of AI in detection of colorectal polyps achieved a sensitivity of 0.95 [95% confidence interval (CI): 0.89-0.98] and an area under the curve (AUC) of 0.79 (95% CI: 0.79-0.82). In the AI-assisted classification, the sensitivity was 0.92 (95% CI: 0.88-0.95) with a specificity of 0.82 (95% CI: 0.71-0.89) and an AUC of 0.94 (95% CI: 0.92-0.96). For the classification of diminutive polyps, the AI-assisted technique yielded a sensitivity of 0.95 (95% CI: 0.94-0.97), a specificity of 0.88 (95% CI: 0.74-0.95), and an AUC of 0.97 (95% CI: 0.95-0.98). For AI-assisted classification under magnifying endoscopy, the sensitivity was 0.954 (95% CI: 0.92-0.96) with a specificity of 0.95 (95% CI: 0.80-0.99) and an AUC of 0.97 (95% CI: 0.95-0.98).Discussion: The AI-assisted technique demonstrates impressive accuracy for the detection and characterization of colorectal polyps and can be expected to be a novel auxiliary diagnosis method. Our study has inevitable limitations including heterogeneity due to different AI systems and the inability to further analyze the specificity and sensitivity of AI for different types of endoscopes.
Background: With the changes in lifestyle and diet, the incidence and mortality of colorectal cancer (CRC) is increasing in China. CRC mainly develops from colorectal adenomas (CRAs). There is a lack of chemopreventative drugs with definite efficacy for CRAs. Tiaochang Xiaoliu Decoction (TXD) was developed by Professor Yunjian Luo and has been used clinically over the last ten years for the prevention of CRA recurrence. To facilitate its clinical use, TXD was further standardized and produced as "Tiaochang Xiaoliu Decoction Granules (TXDG)". A study was designed to investigate the preventive effects of TXDG on the recurrence of CRA.Methods: A randomized, double-blinded, controlled, and multi-center experiment is proposed to assess the effectiveness and safety of TXDG. Patients with CRAs (after complete polypectomy under colonoscopy) will be randomly divided into two groups, one will be treated with TXDG (the TXDG group) and the other will be treated with a TXDG mimetic agent (the TXDG mimetic group). The patients will be treated for 6 months and followed up for 3 years. Follow-up colonoscopy is expected to be carried out within 1 to 3 years after the baseline examinations. The primary outcome measure is adenoma detection rate within 1 to 3 years. The secondary outcome measures are the number, location, and pathology of the adenomas, and the polyp detection rate.Discussion: Reliable objective evidence will be provided to evaluate the efficacy and safety of TXDG as an accessorial therapy for CRA occurrence in post-polypectomy patients.Trial registration: ChiCTR2000035257.
Background: Intestinal spasm and peristalsis during colonoscopy are common but undesirable phenomena, which can easily lead to a missed diagnosis of colorectal polyps and other diseases, and antispasmodic drugs can have adverse side effects. Previous studies find that acupuncture can regulate abnormal gastrointestinal motility. But evidence quality is low and limited at present, and high-quality studies are required. So this study sought to explore the efficacy and safety of acupuncture in inhibiting colonic spasm during endoscopy.Methods: In this prospective, single-blinded, randomized controlled trial, 54 patients experiencing intestinal spasms during colonoscopy were randomly assigned to receive either acupuncture of the bilateral Hegu (LI 4) and Neiguan (PC 6) points (n=27) or sham acupuncture (n=27). The sham points were located 1 cm above the proximal end of the true points and had no known function. The primary outcome was the latency time to colonic spasm suppression, and the secondary outcomes were the duration of colonic spasm suppression, the proportion of patients with rebound spasms within 5 minutes, and adverse events related to acupuncture-related side effects.Results: A total of 54 patients were eligible, and 27 in each group. There was no significant difference in the background characteristics of the patients in the 2 groups. The latency time to spasm suppression of the treatment group was significantly shorter than that of the sham control group (acupuncture: 32.00 s vs. sham: 82.00 s; P<0.001). However, the duration of colonic spasm suppression was similar (acupuncture: 300 s vs. sham: 268 s; P=0.142). No rebound spasms were observed in the treatment group but rebound spasms were observed in 3 patients in the sham control group (acupuncture: 0% vs. sham: 11.1%; P=0.236). No adverse events were observed in either group.Conclusions: Acupuncture of the bilateral Hegu (LI 4) and Neiguan (PC 6) points can shorten the latency time to spasm suppression, and may be used to suppress colonic spasm during colonoscopy.
