Interpretation of the complete scientific connotation of functional foods accurately prior to approval and registration based on animal tests and small sample size human food tests is challenging. Further technical evaluation after market introduction should be carried out on safety, health function and other aspects of those widely used commercial scale production products. According to the analysis report on the consumption situation of post-marketing population submitted when applying for product registration extension since the implementation of the functional food registration and filing management measures more than 3 years ago, the post-marketing evaluation report of functional food still lacks systematic and perfect evidence support. Based on the successful experience of evidence-based medicine and post-marketing evaluation evidence, this paper analyzes the post-marketing evaluation content, evidence source construction, evidence classification and classification of functional food, and puts forward the preliminary idea of constructing post-marketing evaluation evidence body of functional food safety and health function technology from multiple view points, so as to provide insights into evidence system research in this field in the future.
ObjectiveTo summarize the common mouse models and the latest research progress in the basic research of colorectal cancer, introducing advantages, disadvantages and applications of these various models, provide references for the researchers in the selection of mouse models for their experiments.MethodRetrieved the related literatures from databases including PubMed, Web of Science, CNKI and WanFang, and after reading the literatures, different methods were sorted out, analyzed and summarized.ResultsThe mouse models commonly used in colorectal cancer research include the cell-derived xenograft (CDX), patient-derived xenograft (PDX), chemical reagent-induced tumor in situ, transgenic mice (ApcMin/+ mice), tumor cells derived from mice themselves were inoculated to the normal mice, and models of colorectal metastatic tumors (including liver, lung, abdomen and bone metastases, etc.). The CDX model cost shorter time to establish, and the PDX model restored the authentic phenotype of the tumor in patients, but the tumor were both colonized under the skin of nude mice, which lacked authenticity tumor microenvironment. The colorectal cancer in mice induced by chemical reagents and genetically engineered mice imitated the development of colorectal tumor in the situ intestine of mouse, but both of them were time-consuming. The model established by the tumor of mouse own was convenient for basic immune research of colorectal cancer, but the disadvantage was the unreal tumor microenvironment. The colorectal cancer metastasis model was an essential model for the study of the mechanism and treatment in metastasis colorectal tumor, but its establishment required higher operating skills and required the image examination to determine the whether the metastasis tumor was successfully generated or not.ConclusionsDifferent mouse models of colorectal cancer have different emphases, advantages and disadvantages. Researchers need to make accurate selection according to the research purpose and design needs.

ObjectiveTo systematically review the effects of the promotion of appropriate health technology in China and provide reference for improving the promotion of appropriate health technologies.
MethodsDatabases including CBM, VIP, CNKI and WanFang Data were searched for studies about the appropriate health technology in China from inception to August 2014. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of included studies by the evaluation criteria for descriptive studies of MAStARI, an assessment tool developed by JBI Evidence-Based Health Care Center. And then, qualitative descriptive analysis method was used to comprehensively analyze the data from four aspects: medical institutions, regulators, technology promotion medical staff and patients.
ResultsA total of 23 cross-sectional studies and one before-after study were included. The results of qualitative analysis showed that: 1) the technology utilization rate of appropriate health technology extension institutions was more than 70%, the number of outpatients of township and village organizations increased significantly than that of the county level institutions; 2) director of technology extension and managers of hospital were in favor of the promotion of appropriate technology for its good effectiveness, safety, lower medical costs, and skill improvement of medical staff; 3) medical staff mastered the appropriate health technology, they were willing to promote appropriate technology and spoke highly of it for its safety, feasibility and economic effect, and improved their level of technology; 4) in patients' opinion, the appropriate technology reduced the disease course and cost, they spoke highly of it for its acceptance, efficacy and safety.
ConclusionCurrent evidence shows that the promotion of appropriate health technology has achieved good effects. The satisfaction of medical institutions, managers, health service staff and patient is high, but these research results are of poor quality, mostly subjective evaluation, lack of scientific, rational, objective and consistent evaluation criteria, which cannot be used as evaluation evidence for the promotion of appropriate health technology.

Deep brain stimulation (DBS) surgery is an important treatment for patients with Parkinson's disease in the middle and late stages. The accuracy of the implantation of electrode at the location of the nuclei directly determines the therapeutic effect of the operation. At present, there is no single imaging method that can obtain images with electrodes, nuclei and their positional relationship. In addition, the subthalamic nucleus is small in size and the boundary is not obvious, so it cannot be directly segmented. In this paper, a complete end-to-end DBS effect evaluation pipeline was constructed using magnetic resonance (MR) data of T1, T2 and SWI weighted by DBS surgery. Firstly, the images of preoperative and postoperative patients are registered and normalized to the same coordinate space. Secondly, the patient map is obtained by non-rigid registration of brain map and preoperative data, as well as the preoperative nuclear cluster prediction position. Then, a three-dimensional (3D) image of the positional relationship between the electrode and the nucleus is obtained by using the electrode path in the postoperative image and the result of the nuclear segmentation. The 3D image is helpful for the evaluation of the postoperative effect of DBS and provides effective information for postoperative program control. After analysis, the algorithm can achieve a good registration between the patient's DBS surgical image and the brain map. The error between the algorithm and the expert evaluation of the physical coordinates of the center of the thalamus is (1.590 ± 1.063) mm. The problem of postoperative evaluation of the placement of DBS surgical electrodes is solved.

The diagnostic frequency of multiple pulmonary tumor nodules has increased significantly in clinical practice. Among patients with multiple pulmonary nodules, distinguishing between separate primary lung carcinomas and intrapulmonary metastases is critical for accurate tumor staging, therapeutic decision-making, and prognostic evaluation. The consensus document "Differentiating separate primary lung adenocarcinomas from intrapulmonary metastases with emphasis on pathological and molecular considerations: Recommendations from the International Association for the Study of Lung Cancer Pathology Committee" highlights the pivotal role of integrated pathological and molecular analyses in diagnosing and differentiating primary lung adenocarcinomas from intrapulmonary metastatic lesions. It further proposes a combined four-step histologic and molecular classification algorithm for addressing multiple pulmonary tumor nodules of adenocarcinoma histology, providing clinicians with enhanced diagnostic tools to refine staging accuracy, guide therapeutic strategies, and improve prognostic predictions for lung adenocarcinoma. Building on current advancements in global research, this article offers a comprehensive interpretation of the consensus recommendations.
The ideological and political education in standardized residency training plays an important role in cultivating medical talents with noble medical ethics and exquisite medical skills. Teaching evaluation is an important method to promote teaching improvement and optimization. However, there are still some problems and challenges in the evaluation of ideological and political education for standardized residency training. This article proposes the ideological and political education of standardized residency training can be comprehensively evaluated by the context-input-process-product evaluation model from four aspects: background, input, process, and result evaluation. The aim is to provide solid support and guidance for the ideological and political education route in standardized residency training.
ObjectiveTo summarize the evaluation indexes of health resource utilization efficiency in enhanced recovery after surgery (ERAS) , so as to provide reference for the construction of evaluation index system.MethodLiteratures on the allocation, utilization, and efficiency of ERAS health resources at home and abroad in recent years were reviewed and analyzed.ResultsAt present, no systematic evaluation index system of ERAS health resources utilization efficiency had been formed at home and abroad. In the research, the formulation direction of input index mainly included ERAS human resources allocation and material resources allocation, while the formulation direction of output index mainly included ERAS medical resources utilization.ConclusionsThe evaluation system of ERAS health resources utilization efficiency is not perfect and the research scope of its index system is too small, which restricts the standardization promotion of ERAS. It is an urgent problem to construct a scientific evaluation index system for ERAS health resources utilization efficiency.
