Improving the reproducibility of biomedical research results is a major challenge. Transparent and accurate reporting of the research process enables readers to evaluate the reliability of the research results and further explore the experiment by repeating it or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs), provide a checklist that is applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as enhance the reliability, repeatability, and clinical translation of animal experimental results. The use of the ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and completeness of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is based on the best practices following the ARRIVE 2.0 guidelines in international journals, and it interprets, explains, and elaborates in Chinese the fifth part of the comprehensive version of the ARRIVE 2.0 guidelines published in PLoS Biology in 2020 (the original text can be found at https://arriveguidelines.org). This section includes the items 6-11 of Recommended 11 section, covering "Animal Care and Monitoring", "Interpretation/Scientific Implications", "Generalisability/Translation", "Protocol Registration", "Data Access" and "Declaration of Interests". Its aim is to promote a comprehensive understanding and use of the ARRIVE 2.0 guidelines among domestic researchers, to enhance the standardization of experimental animal research and reporting, and to promote high-quality development of experimental animal sciences and comparative medicine research in China.

Purpose: Rare diseases necessitate consistent access to specialized health services. In Korea, despite the growing socioeconomic burden, insufficient comprehensive research is available on patients with rare diseases and their families, particularly concerning factors influencing the length of time to diagnosis. The aim of this study was to thoroughly characterize rare pediatric diseases and explore factors impacting the diagnostic odyssey. Methods: The study enrolled patients under 15 years old seeking medical care at the Seoul National University Children’s Hospital Rare Disease Center between January 2022 and December 2023. Participating patients were required to have been diagnosed with one of the 1,248 rare diseases recognized in Korea. A 33-question survey was developed to assess clinical features of the patients, characteristics of their primary caregivers, and their perceptions of ongoing medical care. Results: The study included 101 patients and their families. Regarding perceived cognitive and motor functions, most families indicated moderate or severe limitations (cognitive, 62.4%; motor, 57.4%). Over half of the families (53.5%) reported discontinuing employment to provide patient care. Neurological symptoms represented the most common initial chief concern, with dermatologic symptoms and laboratory test abnormalities also noted. Three factors were associated with time to diagnosis: the number of hospitals visited, whether the districts of residence and diagnosis aligned, and the age at symptom onset. Conclusion The comprehensive characterization of patients with rare diseases and their families in Korea, along with the identification of factors impacting the diagnostic odyssey, provides key insights for the development of a tailored support system.

The purpose of this systematic review and meta-analysis is to perform a systematic review and meta-analysis of previous studies on minimally invasive scoliosis surgery (MISS) in adolescents with idiopathic scoliosis (AIS). Some data on MISS in AIS compared with conventional open scoliosis surgery (COSS) are conflicting. A systematic literature search was conducted in Medline, Embase, and Cochrane Library, including studies reporting outcomes for MISS in AIS. The meta-analysis compared the operative, radiological, and clinical outcomes and complications between MISS and COSS in patients with AIS. Of the 208 records identified, 15 nonrandomized studies with 1,369 patients (reviews and case reports are excluded) were included in this systematic review and meta-analysis. The mean scale was 6.1, and eight of the 15 included studies showed satisfactory quality using the Newcastle-Ottawa scale. For operative outcomes, MISS had significant benefits in terms of estimated blood loss (standard mean difference [SMD], -1.87; 95% confidence interval [CI], -2.94 to -0.91) and hospitalization days (SMD, -2.99; 95% CI, -4.45 to -1.53) compared with COSS. However, COSS showed significantly favorable outcomes for operative times (SMD, 1.71; 95% CI, 0.92–2.51). No significant differences were observed in radiological outcomes, including Cobb’s angle of the main curve and thoracic kyphosis. For clinical outcomes, MISS showed significant benefits on the visual analog scale score (SMD, -0.91; 95% CI, -1.36 to -0.47). The overall complication rates of MISS were similar to those of COSS (SMD, 0.96; 95% CI, 0.61–1.52). MISS using the posterior approach provides equivalent radiological and clinical outcomes and complication rates compared with COSS. Considering the lower estimated blood loss, shorter hospitalization days, and longer operative times in MISS, COSS is still the mainstay of surgical treatment in AIS; however, MISS using the posterior approach is also one of the surgical options of choice in the case of moderate AIS.

Distal medium vessel occlusions (DMVOs) are thought to cause as many as 25% to 40% of all acute ischemic strokes and may result in substantial disability amongst survivors. Although intravenous thrombolysis (IVT) is more effective for distal than proximal vessel occlusions, the overall efficacy of IVT remains limited in DMVO with less than 50% of patients achieving reperfusion and about 1/3 to 1/4 of the patients failing to achieve functional independence. Data regarding mechanical thrombectomy (MT) among these patients remains limited. The smaller, thinner, and more tortuous vessels involved in DMVO are presumably associated with higher procedural risks whereas a lower benefit might be expected given the smaller amount of tissue territory at risk. Recent advances in technology have shown promising results in endovascular treatment of DMVOs with room for future improvement. In this review, we discuss some of the key technical and clinical considerations in DMVO treatment including the anatomical and clinical terminology, diagnostic modalities, the role of IVT and MT, existing technology, and technical challenges as well as the contemporary evidence and future treatment directions.

OBJECTIVE: To investigate the prevalence of comorbid depression and anxiety and to evaluate the effect of psychological interventions among schistosomiasis patients in China, so as to provide insights into improvements of psychological health among schistosomiasis patients. METHODS: Publications pertaining to comorbid depression and anxiety and psychological interventions among Chinese schistosomiasis patients were retrieved in electronic databases, including CNKI, Wanfang Data, PubMed, Web of Science, and Embase. The prevalence of comorbidity, psychological interventions, and scores for the Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after psychological interventions among Chinese schistosomiasis patients were extracted. The prevalence of comorbid depression and anxiety was investigated among Chinese schistosomiasis patients using a meta-analysis, and the effect of psychological interventions for depression and anxiety was evaluated. RESULTS: A total of 231 publications were retrieved, and 14 publications that met the inclusion and exclusion criteria were included in the final analysis, including 2 English publications and 12 Chinese publications. Meta-analysis showed that the prevalence rates of comorbid depression and anxiety were 61% [95% confidential interval (CI): (48%, 72%)] and 64% [95% CI: (42%, 81%)] among Chinese schistosomiasis patients. Both the SDS [1.45 points, 95% CI: (1.30, 1.60) points] and SAS scores [2.21 points, 95% CI: (2.05, 2.38) points] reduced among Chinese schistosomiasis patients after psychological interventions than before psychological interventions, and the SDS [-0.47 points, 95% CI: (-6.90, -0.25) points] and SAS scores [-1.30 points, 95% CI: (-1.52, -1.09) points] reduced among Chinese schistosomiasis patients in the case group than in the control group. CONCLUSIONS The comorbid anxiety and depression are common among Chinese schistosomiasis patients, and conventional psychological interventions facilitate the improvements of anxiety and depression among schistosomiasis patients.

OBJECTIVES: To investigate the clinical application of endoscopic esophageal dilation in the treatment of corrosive esophageal strictures in children. METHODS: A retrospective analysis was performed on the clinical data of 15 children with corrosive esophageal strictures who underwent endoscopic esophageal dilation in Children's Hospital, Zhejiang University School of Medicine. The clinical features, treatment modality of endoscopic esophageal dilation, number of dilations, complications, and prognosis were reviewed. RESULTS: A total of 96 esophageal dilations were performed in the 15 children with corrosive esophageal strictures, with a median of 6 dilations per child. Among them, 9 children (60%) underwent 6 or more dilations. The children with a stricture length of >3 cm had a significantly higher number of dilations than those with a stricture length of ≤3 cm (P<0.05). The children with strictures in a single segment had a significantly better treatment outcome than those with strictures in multiple segments (P=0.005). No complication was observed during all sessions of dilation. The overall effective rate (including significant improvement and improvement) of endoscopic esophageal dilation treatment was 87%, with 2 cases of failure. CONCLUSIONS Endoscopic esophageal dilation is an effective and relatively safe treatment method for corrosive esophageal strictures in children, and children with strictures in a single segment tend to have a better treatment outcome than those with strictures in multiple segments.
