Abstract To analyzes the characteristics, problems and enlightenment of physical activity observation tools, so as to provide reference for researchers to quickly and accurately choose appropriate observation tools to evaluate children s and adolescents physical activity. Literature search is conducted in eight databases of Chinese and English, including CNKI, Wanfang, VIP, Web of Science, PubMed, Medline, ERIC, and SPORTDiscus. Ultimately, eight observation tools for assessing physical activity in children and adolescents are included. Through summarization and comparison, it is found that the applications of those tools cover multiple age groups, the observation indicators cover multiple dimensions for each with varying emphases, and the applicable contexts vary in their specific background information, and recording methods tend to be quantitative. However, several issues remain to be addressed in practical applications. First, the observation indicators need to be supplemented and improved; second, physical activity in community environments and academic classrooms requires further attention; third, physical activity intensity needs to be scientifically evaluated; fourth, observation and recording methods need to be integrated and innovated; fifth, the number of observation subjects needs to be expanded. Future research could focus on developing observation tools tailored to the characteristics of Chinese children and adolescents, while drawing on foreign observation tools to comprehensively assess physical activity among children and adolescents.

Objective To analyze the medication rule of Traditional Chinese Medicine(TCM)in treating diabetes nephropathy(DN)and to explore the interaction between core components and key targets.Methods Based on the ancient and modern medical case cloud platform,the medication rules of TCMs and the drug pairs with the highest frequency in treating DN were summarized.Then the network pharmacology approach was utilized to analyze the pharmacodynamic material basis and mechanisms of the highest frequency-drug pairs.The potential targets were predicted by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)databases.TTD,DISGENET,and GENECARD databases were used to obtain the related targets of DN and screen out the potential targets for DN.In order to clarify the relationships between the active ingredients,the core targets,and pathways,STRING and Cytoscape 3.7.1 software were used to construct the protein-protein interaction(PPI)network and core drugs-ingredients-targets-disease interaction network,DAVID database was screened for Kyoto Encyclopedia of Genes and Gnomes(KEGG)enrichment analysis of core targets.Sybyl 2.1 software and biofilm interference verify the combined capacity between the core ingredients and key targets.Results Among 183 prescriptions,Astragali Radix had the highest use frequency and average dose,43 times and 37 g,respectively,followed by Salviae miltiorrhizae Radix and Poria cocos.To find the core combined with the highest confidence in association analysis was astragalus,salvia miltiorrhiza,and tuckahoe.Correlation analysis indicates that the core combination with the highest confidence was Astragali Radix-Salviae miltiorrhizae Radix-Poria cocos.Network pharmacologic showed 89 potential targets and 15 key signaling pathways for the treatment of DN by the drug pair.TNF signaling pathway,Nod-like receptor signaling pathway,and MAPK signaling pathway were disease-related pathways,and IL-6,TNF,and vascular endothelial growth factor A(VEGFA)were core targets.Isorhamnetin and quercetin of the drug pair had high binding ability with IL6,the scores were 8.2 and 7.4,respectively,and the dissociation constants(KD)were 5.6×10-5 mol·L-1 and 6.8×10-5 mol·L-1,respectively.Conclusion This study preliminarily finds the prescription rule of treating DN with Astragali Radix-Salviae miltiorrhizae Radix-Poria cocos as the core drug pair,isorhamnetin,and quercetin are probably the main active compounds of this drug pair in DN treatment,which provides a basis for clinical treatment and drug discovery of DN.

Objective:To evaluate the effect of sleep deprivation on the expression of sirtuin 6 (SIRT6) in the cerebellum of immature mice.Methods:Fifty SPF healthy male C57BL/6 mice, aged 4 weeks, weighing 14-16 g, were divided into 2 groups ( n=25 each) using a random number table method: control group (Con group) and sleep deprivation group (SD group). The chronic sleep deprivation model was prepared by using the multi-platform water environment method, with 20 h of sleep deprivation per day for 10 consecutive days. After sleep deprivation, a balance beam experiment was performed to test the balance and coordination ability of mice. The mice were sacrificed after anesthesia and cerebellar lobular IV-VI (4-6 cb) tissues were taken for microscopic examination of the ultrastructure (with a transmission electron microscope) and for determination of the dendritic spine density of cerebellar 4-6cb Purkinje neurons (by Golgi staining), co-expression of SIRT6 and Calbindin D-28k (CbD-28k) and expression of glucose transporter Glut3 of cerebellar 4-6cb (by immunofluorescence staining). Results:Compared with group Con, the duration of passage through the balance beam was significantly prolonged, and the number of posterior foot slips was increased, the synaptic gap of cerebellar 4-6cb neurons was increased, the thickness of postsynaptic density was increased, the density of dendritic spines of Purkinje cells and the number of positive cells co-expressing SIRT6 and CbD-28k were decreased, and the expression of Glut3 was down-regulated in group SD ( P<0.05). Conclusions:The mechanism by which sleep deprivation decreases the abilities of balance and coordination is related to down-regulating SIRT6 expression in cerebellar Purkinje cells and decreasing neuronal glucose metabolism, thus damaging the synaptic plasticity of cerebellum in immature mice.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

BACKGROUND:N6-methyladenosine(m6A)is a hot research topic in the mechanism of pathological cardiac remodeling and plays an important role in the development of cardiovascular diseases. OBJECTIVE:To summarize the possible mechanism by which m6A modification in non-coding RNAs regulates the main processes of pathological cardiac remodeling,such as pathological cardiac hypertrophy,cardiomyocyte death,myocardial fibrosis and vascular remodeling. METHODS:"m6A,non-coding RNA,pathological cardiac hypertrophy,cardiomyocyte apoptosis,cardiomyocyte pyroptosis,cardiomyocyte ferroptosis,myocardial fibrosis,vascular remodeling"were used as search terms in Chinese and English.Relevant literature from CNKI,PubMed and Web of Science databases published from January 1974 to April 2023 was retrieved,and finally 86 eligible articles were reviewed. RESULTS AND CONCLUSION:m6A modification is a highly dynamic and reversible modification.Pathological cardiac remodeling mainly involves pathological cardiac hypertrophy,cardiomyocyte apoptosis,cardiomyocyte pyroptosis,cardiomyocyte ferroptosis,myocardial fibrosis and vascular remodeling.m6A-related enzymes can regulate pathological cardiac remodeling processes through various non-coding RNAs and different signaling pathways,which can be used as a new potential intervention for cardiovascular diseases.In pathological cardiac remodeling,research on the regulatory relationship between m6A modification and non-coding RNAs is still in its infancy.With the development of epigenetics,m6A modification in non-coding RNAs is expected to have a new development in the regulation of pathological cardiac remodeling.

Conclusion Compared with non-D-type patients,CHD patients with D-type personality exhibit lower levels of health empowerment and perceived control,and higher level of experiential avoidance,which may negatively impact on health behaviors.

With the process of China’s aging population intensifying， palliative care， as an important guarantee for improving the quality of life of terminally ill patients， is receiving more and more social attention， and the demand is constantly increasing. Palliative care needs versatile professionals， and general education can enhance people’s awareness and understanding of it， enabling more people to understand， accept， and participate in palliative care. With the advancement of knowledge and technology in palliative care， the traditional cramming education models are no longer able to meet the actual needs. Therefore， there is an urgent need to innovate palliative care education strategies. By analyzing the current problems in the general education of palliative care in China， this paper proposed thoughts and suggestions for general and innovative education of palliative care in several aspects， such as establishing general and innovative education systems and evaluation systems of palliative care， diversifying educational contents and methods， strengthening medical staffs training， promoting diversified student groups， and strengthening the popularization of palliative care knowledge among the public.

Sepsis presents challenges in clinical treatment due to its high incidence,difficult treatment,and high fatality rate.The intestine has long been considered the"motor"of multiple organ dysfunction syndrome(MODS).Intestinal dysfunction is one of the common complications of sepsis,which is often neglected due to its hidden occurrence and poor clinical efficacy,leading to poor prognosis.Therefore,it is of great significance to explore the pathogenesis and treatment of intestinal dysfunction in sepsis.As an effective supplement for the clinical treatment of intestinal dysfunction in sepsis,Traditional Chinese medicine has been paid more and more attention by clinicians.This article summarizes the research progress on the pathogenesis of sepsis-induced intestinal dysfunction and the clinical application of traditional Chinese medicine(TCM),aiming to provide more ideas and references for the clinical treatment of sepsis.

Objective:To explore the inhaled allergen sensitization status of children with allergic rhinitis in Beijing City, and to provide evidence for diagnosis and treatment, allergen avoidance and disease management.Methods:In this cross-sectional study, data from 8 741 children with allergic rhinitis treated in Children′s Hospital affiliated to Capital Institute of Pediatrics from January 2020 to December 2021 were retrospectively analyzed. The subjects were divided into toddlers (1 y-≤3 y), preschool children (3 y-≤6 y), school aged children (6 y-≤12 y) and adolescents (12 y-≤18 y) and according to season the subjects were divided 4 groups: spring, summer, autumn, winter. The ImmunoCAP system was used to detect serum allergens sIgE.Results:The positive rates of inhaled allergens among subjects in sequence from high to low were: mx2 [molds (penicillium speciosum/mycosporum multiflorum/aspergillus fumigatus/alternatia/demodex longum)], w6 (artemisiaargyi), wx5[weeds pollen combination (ragweed/artemisia argyi/marguerite/dandelion/goldenrod)], w1(ragweed), tx5[trees pollen combination (populus tomentosa/hazel/elm/willow)], d2(dermatophagoides farina), d1(dermatophagoides pteronyssinus), ex1[animal dander combination (catdander/dogdander/horsedander/cowdander)], i6(blattella germanica). Boys have higher positive rates of sIgE responses than girls (54.20% vs. 47.96%, χ 2= 8 923.000, P<0. 001). The primacy inhaled allergen in toddlers, preschool children and school aged children was mx2 (37.75%, 39.99% and 42.46%), and in adolescents w6 (45.45%), d2 (41.51%) and d1 (37.74%) were the largest categories. Except for mold, the positive detection rate of inhaled allergens increased gradually with age. In different seasons, the positive rates of ex1 (24.77% vs. 18.26% vs. 17.10% vs. 12.39%, χ 2= 31.469, P<0.001), wx5 (20.18% vs. 28.62% vs. 39.96% vs. 12.53%, χ 2= 155.788, P<0.001), mx2 (31.79% vs. 50.96% vs. 36.99 vs. 28.81, χ 2= 208.444, P<0.001), tx5 (28.14% vs. 27.01% vs. 26.77% vs. 9.64%, χ 2= 60.613, P<0.001) and w6 (26.57% vs. 34.39% vs. 52.11% vs. 25.35%, χ 2= 17.710, P<0.001) were statistically different among groups. Mx2 in spring and summer was the highest categories (31.79%, 50.96%), and w6 in autumn was the highest (52.11%). Conclusions:In this study, mx2 was the most important allergen in children (≤12 y) and w6 was the highest in adolescents treated in Children′s Hospital affiliated to Capital Institute of Pediatrics from January 2020 to December 2021 in Beijing City. The types of allergens and positivity rates were different for different sexes, ages and seasons.

Objective To develop a risk prediction model for postoperative malnutrition in children with congenital heart disease(CHD)and to verify it both internally and externally.Methods By a convenience sampling method,300 CHD children treated at a tertiary hospital in Shandong Province from January 2018 to December 2021 were selected as a modeling group,and 129 children from January 2022 to June 2023 were selected as a validation group.Data on patient demographics,disease-specific variables,therapeutic interventions,and nursing care parameters were collected.Single factor and logistic regression were employed to construct a risk prediction model for postoperative malnutrition in CHD children,and the nomogram was drawn and its prediction effect was evaluated.Results The incidence of postoperative malnutrition among CHD children was 33.10％.Logistic regression analysis revealed that risk factors for malnutrition in children included birth weight＜2.5 kg,preoperative malnutrition,negative fluid balance 1 week after surgery,and long duration of cardiopulmonary bypass(P＜0.05).The area under the receiver operating characteristic curve of the modeling group was 0.933;the sensitivity was 83.30％;the specificity was 90.90％.The Hosmer-Lemeshow test showed that x2=7.765(P=0.457).The AUC of the validation group was 0.918;the sensitivity was 87.20％;the specificity was 90.00％.The Hosmer-Lemeshow test showed that x2=4.947(P=0.763).Calibration curves for both groups indicated good calibration of the model,and the clinical decision curves demonstrated its practical clinical utility.Conclusion The risk prediction model developed in this study exhibits good predictive ability,which can provide a reference for medical staff to early identify high-risk infants for postoperative malnutrition following CHD surgery and to formulate targeted intervention measures.
