ObjectiveBased on functional near-infrared spectroscopy (fNIRS), we investigated the brain activity characteristics of gross motor tasks in children with autism spectrum disorder (ASD) and motor dysfunctions (MDs) to provide a theoretical basis for further understanding the mechanism of MDs in children with ASD and designing targeted intervention programs from a central perspective. MethodsAccording to the inclusion and exclusion criteria, 48 children with ASD accompanied by MDs were recruited into the ASD group and 40 children with typically developing (TD) into the TD group. The fNIRS device was used to collect the information of blood oxygen changes in the cortical motor-related brain regions during single-handed bag throwing and tiptoe walking, and the differences in brain activation and functional connectivity between the two groups of children were analyzed from the perspective of brain activation and functional connectivity. ResultsCompared to the TD group, in the object manipulative motor task (one-handed bag throwing), the ASD group showed significantly reduced activation in both left sensorimotor cortex (SMC) and right secondary visual cortex (V2) (P<0.05), whereas the right pre-motor and supplementary motor cortex (PMC&SMA) had significantly higher activation (P<0.01) and showed bilateral brain region activity; in terms of brain functional integration, there was a significant decrease in the strength of brain functional connectivity (P<0.05) and was mainly associated with dorsolateral prefrontal cortex (DLPFC) and V2. In the body stability motor task (tiptoe walking), the ASD group had significantly higher activation in motor-related brain regions such as the DLPFC, SMC, and PMC&SMA (P<0.05) and showed bilateral brain region activity; in terms of brain functional integration, the ASD group had lower strength of brain functional connectivity (P<0.05) and was mainly associated with PMC&SMA and V2. ConclusionChildren with ASD exhibit abnormal brain functional activity characteristics specific to different gross motor tasks in object manipulative and body stability, reflecting insufficient or excessive compensatory activation of local brain regions and impaired cross-regions integration, which may be a potential reason for the poorer gross motor performance of children with ASD, and meanwhile provides data support for further unraveling the mechanisms underlying the occurrence of MDs in the context of ASD and designing targeted intervention programs from a central perspective.

BACKGROUND:Although traditional therapies,including drugs and surgery,cannot repair the damaged myocardial tissue,the mortality rate of myocardial infarction remains high.Stem cells provide the possibility to solve this problem due to their self-renewal and multi-directional differentiation potential. OBJECTIVE:To analyze the research progress of stem cell therapy for myocardial infarction in recent ten years by bibliometric analysis. METHODS:The related articles on stem cells and myocardial infarction published in SCI-E and SSCI from January 1,2012 to December 1,2022 in the Web of Science database were searched.EXCEL,CiteSpace and VOSviewer software were used to make statistical and visualization analyses of the data such as the number of publications,authors,institutions,journals,countries and keywords. RESULTS AND CONCLUSION:A total of 3 210 core articles were published,and the total number increased year by year.hausenloy,derek j.is the author with the largest number of publications,China is the country with the largest number of publications,and the Fourth Military Medical University is the institution with the largest number of publications.The research hotspots in this field are changing from cell experiments and animal experiments to clinical trials.In the past ten years,research in this field has been highly popular and still has great development prospects.It is necessary to promote international and inter-agency exchange and learning,and further explore the role of stem cells in the treatment of myocardial infarction.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To construct an evaluation index system of scientific and technological achievements transfor-mation in affiliated hospitals of universities and colleges based on a logical model,and to provide reference for scien-tific and systematic measurement of scientific and technological achievements transformation in affiliated hospitals of universities and colleges.Methods The first draft of the evaluation index system was drawn up by combing the re-search literature and laws and policies related to the evaluation of scientific and technological achievements transfor-mation in domestic hospitals,and two rounds of Delphi expert consultation were carried out to determine the evalua-tion index system.Results The expert positive coefficient of both rounds was 100%,the authority coefficient was 0.875 and 0.874,and Kendall's W coefficient increased round by round.Finally,an evaluation system covering 4 first-level indicators,12 second-level indicators and 44 third-level indicators of scientific and technological achieve-ments transformation in affiliated hospitals of colleges and universities was determined.Conclusion The evaluation in-dex system of scientific and technological achievements transformation in affiliated hospitals of colleges and universi-ties has certain reliability and scientificity,with obvious main characteristics,and has important guiding significance and practical value for promoting the optimization of scientific and technological achievements transformation in affiliated hospitals of colleges and universities and improving the transformation efficiency.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.
