Medical ethic and publication ethic was more and more and important with the development of trial registration and systematic review registration promoted by the World Health Organization and the Cochrane Collaboration. Chinese Trial Registration and Publication Collaboration (ChiCTRPC) published the first statement to implement trial registration in China. We suggested that trial registration should be combined with ethic review and described the new definition of publication ethic in the second meeting by ChiCTRPC in 2010. In the the third meeting of ChiCTRPC in 2011, Experts from many fields communicated adequately and reached consensus. We summarized the experiences and lessons in the 5 years after the first statement of ChiCTRPC was published. Based on the latest progress of research ethic, publication ethic, trial registration, and systematic review registration, we drafted this explanation document for the second statement of ChiCTRPC to realize good research practice (RGP), good publication practice (GPP), and good translation practice (GTP) by implementing research ethic and publication ethic.
Protein post-translational modifications (PTMs) are critical for modulating protein structure and function. Among these, lysine lactylation (Kla) has garnered significant attention in recent years as a newly discovered PTM. Although Kla has been thoroughly investigated in eukaryotic systems, its study in prokaryotes, especially bacteria, remains comparatively limited. Emerging research highlights that bacterial Kla, operating through dynamic modification mechanisms, is pivotal in processes such as growth and metabolism, virulence control, pathogenicity, and host-pathogen interactions. This article provides a comprehensive overview of the latest progress in bacterial Kla research, emphasizing its historical discovery, distinct modification features, and underlying molecular regulatory mechanisms. We further explore the regulatory roles of this modification in bacterial physiological processes and pathogenesis, concluding with a discussion of current research challenges and prospective future developments.
Objective By summarizing the latest research progress of circRNA translation mechanism and reviewing the research progress of circRNA translation in various digestive system tumors, this paper is aiming to forecast the clinical application prospect of circular RNA translation and provide ideas for the diagnosis and treatment of digestive system neoplasms. Method The literatures on the translation of circRNA and its role in digestive system neoplasms were searched and reviewed. Results As a member of the non-coding RNA family, circRNAs are generally considered to be difficult to encode proteins as translation templates. With the rapid development of bioinformatics, next-generation sequencing, proteomics and translation omics, it has been found that many kinds of circRNAs can encode proteins or peptides in a cap-independent manner and play a critical role in the development of digestive system neoplasms, including gastric cancer, liver cancer and colorectal cancer. Conclusions The translation function of circRNA plays an important role in the development and progression of digestive system tumors, and its translation products may become new diagnostic or therapeutic targets for digestive system tumors, with great clinical transformation potential.
Testing Treatments is a book to help the public understand how to validate the efficacy of testing treatments and the possible bias and error in clinical trial, as well as to call for help to promote good study thus to improve the quality of health care. No matter for the first or the second edition, this book is very popular around the world, and its second edition has been translated into more than ten languages. To help the readers understand the content of the book, we established a website (www.testingtreatments.org) and other sibling sites in different languages. The website not only provided the full-texts to download, but also collected various popular science resources (videos, audios and cartoons) to help the readers assimilate more knowledge. The editors of all the different language websites have established an TTi Editorial Alliance to share experience and provide each other with mutual support, thus to promote health professionals, patients and public around the world to use reliable research to inform their health decisions.
Objective To investigate the effectiveness of slope-reducing tibial osteotomy and anterior cruciate ligament (ACL) revision in the treatment of patients with primary ACL reconstruction failure and abnormally increased posterior tibial slope (PTS). Methods The clinical data of 9 patients with primary ACL reconstruction failure and abnormally increased PTS (≥17°) who met the selection criteria between January 2018 and January 2020 were retrospectively analyzed. There were 8 males and 1 female; the age ranged from 21 to 42 years, with a median age of 30 years. Lachman test was positive in 9 patients. Pivot-shift test was negative in 6 cases, degree Ⅰ positive in 2 cases, and degree Ⅱ positive in 1 case. The PTS was (17.78±1.09)° and the anterior tibial translation (ATT) was (11.58±1.47) mm. The International Knee Documentation Committee (IKDC) score was 51.0±3.8, Lysholm score was 49.7±4.6, and Tegner score was 3.7±0.7. The time from primary reconstruction to revision was 12-33 months, with an average of 19.6 months. Slope-reducing tibial osteotomy and ACL revision were performed. The improvement of knee function was evaluated by IKDC score, Lysholm score, and Tegner score; Lachman test and Pivot-shift test were used to evaluate the stability of knee joint. PTS and ATT were measured to observe the morphological changes of knee joint. Results All the incisions healed by first intention, and there was no complication such as incision infection, fat liquefaction, necrosis, deep vein thrombosis of lower extremities, and neurovascular injury. All 9 patients were followed up 12-36 months, with an average of 25.8 months. At last follow-up, Lachman test and pivot-shift test were negative. IKDC score was 85.0±4.0, Lysholm score was 87.7±2.8, Tegner score was 6.8±0.7, PTS reduced to (9.89±0.60)°, and ATT shortened to (0.91±0.29) mm, which were significantly improved when compared with those before operation (P<0.05). ConclusionSlope-reducing tibial osteotomy and ACL revision in the treatment of patients with primary ACL reconstruction failure and abnormally increased PTS has a satisfactory short-term effectiveness. It can improve the stability of knee joint and maintain the normal shape of knee joint.

ObjectiveTo translate evidence of "HIV/AIDS Clinical Nursing Practice Guideline" into clinical practice, in order to reduce the incidence and severity of symptoms of AIDS and to improve the quality of life of patients. MethodsWe integrated the best evidence into the HIV/AIDS inpatient unit of a tertiary hospital for infectious disease in Shanghai, China between September 2013 and February 2015. Based on the "Ottawa Model of Research Use", this study was divided into four stages: evaluating the status quo, building the evidence-based strategy, applying evidence-based decision-making, and evaluating results and reflecting. 148 patients were either assigned to an intervention group with HIV/AIDS-related symptom management protocol (n=74), or to a usual care group (n=74) for the duration of their antiretroviral therapy. Then Medical Outcomes Questionnaire (MOS-HIV) were applied to evaluate the life quality after intervention. ResultsMixed-effects regression indicated significant difference between groups across time in total MOS-HIV score. The intervention group increased more than the control group 2.72 points in total MOS-HIV scores per month (P<0.05). ConclusionThe evidence-translation and evidence-based decision-making of "HIV/AIDS Clinical Nursing Practice Guideline" can regulate nurse behavior, raise the quality of clinical care and improve the patients' quality of life.
Brain–computer interface (BCI) technology faces structural risks due to a misalignment between its technological maturity and industrialization expectations. This study used the Technology Readiness Level (TRL) framework to assess the status of major BCI paradigms—such as steady-state visual evoked potential (SSVEP), motor imagery, and P300—and found that they predominantly remained at TRL4 to TRL6, with few stable applications reaching TRL9. The analysis identified four interrelated sources of bubble risk: overly broad definitions of BCI, excessive focus on decoding performance, asynchronous translational progress, and imprecise terminology usage. These distortions have contributed to the misallocation of research resources and public misunderstanding. To foster the sustainable development of BCI, this paper advocated the establishment of a standardized TRL evaluation system, clearer terminological boundaries, stronger support for fundamental research, enhanced ethical oversight, and the implementation of inclusive and diversified governance mechanisms.
To address the issues of difficulty in preserving anatomical structures, low realism of generated images, and loss of high-frequency image information in medical image cross-modal translation, this paper proposes a medical image cross-modal translation method based on diffusion generative adversarial networks. First, an unsupervised translation module is used to convert magnetic resonance imaging (MRI) into pseudo-computed tomography (CT) images. Subsequently, a nonlinear frequency decomposition module is used to extract high-frequency CT images. Finally, the pseudo-CT image is input into the forward process, while the high-frequency CT image as a conditional input is used to guide the reverse process to generate the final CT image. The proposed model is evaluated on the SynthRAD2023 dataset, which is used for CT image generation for radiotherapy planning. The generated brain CT images achieve a Fréchet Inception Distance (FID) score of 33.159 7, a structure similarity index measure (SSIM) of 89.84%, a peak signal-to-noise ratio (PSNR) of 35.596 5 dB, and a mean squared error (MSE) of 17.873 9. The generated pelvic CT images yield an FID score of 33.951 6, a structural similarity index of 91.30%, a PSNR of 34.870 7 dB, and an MSE of 17.465 8. Experimental results show that the proposed model generates highly realistic CT images while preserving anatomical accuracy as much as possible. The transformed CT images can be effectively used in radiotherapy planning, further enhancing diagnostic efficiency.
The Clearinghouse plays an important role in knowledge translation in western developed countries. It consistently provides the latest evidence to target customers according to its strict criteria in the specific fields. Clearinghouse is objectively and scientifically designed to assess the scientific nature and the practical applicability of evidence to provide the best current evidence to different service practitioners. It emphasizes much on the process from "knowledge production" to "knowledge utilization", which effectively fills the gap between scientific research and practice. It will play an increasing important role in the knowledge translation in the future. This article specifically introduces its history of development, characteristics and application and sets the construction of Chinese Clearinghouse for Evidence Translation in Child & Aging Health (CCET) as an example, fully elaborating the application status of Clearinghouse and providing assistance for evidence informed decision making.
