Neuroscience is a significant frontier discipline within the natural sciences and has become an important interdisciplinary frontier scientific field. Brain is one of the most complex organs in the human body, and its structural and functional analysis is considered the “ultimate frontier” of human self-awareness and exploration of nature. Driven by the strategic layout of “China Brain Project”, Chinese scientists have conducted systematic research focusing on “understanding the brain, simulating the brain, and protecting the brain”. They have made breakthrough progress in areas such as the principles of brain cognition, mechanisms and interventions for brain diseases, brain-like computation, and applications of brain-machine intelligence technology, aiming to enhance brain health through biomedical technology and improve the quality of human life. Due to limited understanding and comprehension of neuroscience, there are still many important unresolved issues in the field of neuroscience, resulting in a lack of effective measures to prevent and protect brain health. Therefore, in addition to actively developing new generation drugs, exploring non pharmacological treatment strategies with better health benefits and higher safety is particularly important. Epidemiological data shows that, exercise is not only an indispensable part of daily life but also an important non-pharmacological approach for protecting brain health and preventing neurodegenerative diseases, forming an emerging research field known as motor neuroscience. Basic research in motor neuroscience primarily focuses on analyzing the dynamic coding mechanisms of neural circuits involved in motor control, breakthroughs in motor neuroscience research depend on the construction of dynamic monitoring systems across temporal and spatial scales. Therefore, high spatiotemporal resolution detection of movement processes and movement-induced changes in brain structure and neural activity signals is an important technical foundation for conducting motor neuroscience research and has developed a set of tools based on traditional neuroscience methods combined with novel motor behavior decoding technologies, providing an innovative technical platform for motor neuroscience research. The protective effect of exercise in neurodegenerative diseases provides broad application prospects for its clinical translation. Applied research in motor neuroscience centers on deciphering the regulatory networks of neuroprotective molecules mediated by exercise. From the perspectives of exercise promoting neurogenesis and regeneration, enhancing synaptic plasticity, modulating neuronal functional activity, and remodeling the molecular homeostasis of the neuronal microenvironment, it aims to improve cognitive function and reduce the incidence of Parkinson’s disease and Alzheimer’s disease. This has also advanced research into the molecular regulatory networks mediating exercise-induced neuroprotection and facilitated the clinical application and promotion of exercise rehabilitation strategies. Multidimensional analysis of exercise-regulated neural plasticity is the theoretical basis for elucidating the brain-protective mechanisms mediated by exercise and developing intervention strategies for neurological diseases. Thus,real-time analysis of different neural signals during active exercise is needed to study the health effects of exercise throughout the entire life cycle and enhance lifelong sports awareness. Therefore, this article will systematically summarize the innovative technological developments in motor neuroscience research, review the mechanisms of neural plasticity that exercise utilizes to protect the brain, and explore the role of exercise in the prevention and treatment of major neurodegenerative diseases. This aims to provide new ideas for future theoretical innovations and clinical applications in the field of exercise-induced brain protection.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To evaluate the incidence of malnutrition in hospitalized patients with liver cirrhosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria, and to identify the risk factors of malnutrition.Methods:A total of 305 inpatients with liver cirrhosis were included from the Department of Gastroenterology of the People's Hospital of Xiangxi Tujia and Miao Autonomous Prefecture between January 1, 2023 to September 30, 2023. The patient characteristics, clinical indicators, complications, unplanned readmission within 90 days and death outcomes were collected. Malnutrition was diagnosed according to the GLIM criteria, the differences in various indicators were compared between the malnutrition group and the well-nourished group, and the influencing factors of malnutrition were analyzed. The relationship between malnutrition and short-term prognosis was also discussed.Results:Among the enrolled patients, 188 (61.6%) were diagnosed with malnutrition per GLIM criteria, of whom 18 were with Child-Turcotte-Pugh (CTP) Grade A liver function, 108 Grade B, and 62 Grade C. Compared with the well-nourished group, the malnutrition group showed prolonged length of hospital stay ( P<0.001), lower body mass index P=0.003), lower levels of red blood cell count, hemoglobin, serum albumin, serum albumin/globulin ratio, and serum calcium ( P<0.001), higher level of aspartate aminotransferase ( P=0.025), and increased levels of C-reactive protein, total bilirubin, international normalized ratio, plasma prothrombin time and model for end-stage liver disease score ( P<0.001). The proportion of patients with ascites, esophageal gastric varices, upper gastrointestinal bleeding, hepatic encephalopathy and unplanned readmission within 90 days were significantly increased ( P<0.001) in malnutrition group, and the mortality within 90 days was also higher ( P=0.042). Logistic regression analysis identified lower body mass index level ( OR=0.910, P=0.038), ascites ( OR=0.065, P<0.001) and upper gastrointestinal bleeding ( OR=0.184, P=0.001) as the influencing factors of malnutrition in liver cirrhosis patients. Conclusions:The prevalent malnutrition in patients with liver cirrhosis may affect the short-term prognosis. Lower body mass index, ascites and upper gastrointestinal bleeding are influencing factors for malnutrition in liver cirrhosis patients. Therefore, patients with liver cirrhosis should be screened for malnutrition to allow timely nutritional intervention measures.

The influencing factors of health seeking behavior in SUI older women included urinary incontinence cognition, symptom severity, quality of life, coping efficacy, stigma, access to medical resources, and demographic factors.Conclusions:The cognition of urinary incontinence is the primary factor affecting the health seeking behavior of older women with SUI. Medical and nursing staff should consider cultural differences in clinical practice and assist older women in improving their awareness of urinary incontinence, in order to enhance their health seeking literacy and quality of life.

RNA m6A modification is mainly regulated by m6A methyltransferase,m6A demethylase and m6A binding protein,which can change gene transcription and thus regulating physiological and patholog-ical processes.In recent years,more and more evidences have shown that m6A methylation plays an im-portant role in the regulation of tumor microenvironment(TME).It can affect the occurrence,develop-ment and metastasis of various types of cancer.Myeloid-derived suppressor cells(MDSCs),a group of immature myeloid cells,are important immune cells in TME which can be pathologically activated.It mainly inhibits the activity of T cells,so as to promote the immune escape of malignant tumors.Studies have shown that MDSC,a new and promising target for immunotherapy,can reshape the immunosuppres-sive microenvironment and modulate the efficacy of cancer immunotherapy.The role of m6A modification in the activation,differentiation and effector function of some immune cells has been widely concerned.However,the research on how m6A modification affects MDSC is still very limited.Therefore,it is par-ticularly important to further explore the relationship between them.Based on the introduction of MDSC and RNA m6A modification,this review summarizes the mechanism and research progress of RNA m6A modification in regulating MDSC in TME in order to provide new strategies for targeting MDSC from the perspective of epigenetic modification.

Objective:To explore the value of 18F-fibroblast activation protein inhibitor (FAPI) PET/CT in the assessment of early-stage graft fibrosis (S1-S2) after liver transplantation (LT). Methods:From November 2021 to April 2022, 17 adult liver transplant recipients (12 males and 5 females; age (52.6±7.9) years) in the Affiliated Hospital of Qingdao University were enrolled retrospectively in this study. All 17 patients received laboratory examinations, FibroScan, 18F-FAPI PET/CT and liver biopsy. According to the Scheuer scoring system, hepatic tissue was divided into no fibrosis (S0) and early fibrosis (S1-S2). Independent-sample t test was used to compare SUV max between two groups, and Mann-Whitney U test was used to compare liver stiffness measurement (LSM). ROC curve analysis was used to evaluate the diagnostic efficacy of LSM and SUV max in the early fibrosis of liver grafts. Delong test was used to compare the difference of AUCs. Results:Among 17 adult LT recipients, 11 were in stage S0, 5 were in stage S1, and 1 was in stage S2. There were significant differences in LSM and SUV max between no fibrosis group and early fibrosis group (LSM: 5.4(4.7, 6.6) vs 12.9(5.6, 19.9) kPa, z=-2.01, P=0.044; SUV max: 1.7±0.8 vs 3.9±1.6, t=-3.14, P=0.019). The threshold value of LSM in predicting early-stage graft fibrosis was 8.2 kPa and the AUC was 0.80 (95% CI: 0.54-0.95), which was 2.0 and 0.92 (95% CI: 0.78-1.00) for SUV max respectively. There was no significant difference in AUC between the two tools ( z=0.80, P=0.421). Conclusion:18F-FAPI PET/CT can precisely evaluate the early fibrosis of allografts, with the similar diagnostic efficacy with FibroScan (LSM), which is expected to be a new non-invasive diagnostic tool for predicting the early-stage of graft liver fibrosis.

Objective To explore the effectiveness of different intervention strategies in response to outbreaks of emerging highly pathogenic respiratory infectious diseases(RIDs)in mega-city in China,and provide decision-ma-king basis for effective response to emerging RIDs.Methods A susceptible-exposed-infectious-recovered(SEIR)transmission dynamics model was constructed,referencing to and combining the pathogenicity and infectivity para-meters of previous emerging RIDs.The outbreak of emerging highly pathogenic RIDs with low,moderate,and high infectivity in a mega-city with a population of 10 million in China was simulated,the development of the epidemic within 100 days after implementing different combinations of non-pharmaceutical interventions(NPIs)in response to the outbreak was compared.Results When highly pathogenic RIDs outbreak occurred,and if its infectivity was low(R0 was about 1.5),it was unnecessary to adopt strict NPIs to control epidemic.If its infectivity was moderate(R0 was about 6),different intensities of NPIs were needed based on its existing infection scale.When the initial num-ber of infected cases was 50,moderate-intensity NPIs could keep the infection and death at a low level within 100 days,and the required bed number in hospital for cases could be kept below the national average reserve level.But when the scale of infection exceeded 100 cases,high-intensity NPIs were needed to control the development of the epidemic.In the case of extremely strong infectivity(R0 was about 10),regardless of the scale of infection,only immediate high-intensity NPIs could control the epidemic,infection and death scale.Conclusion In case of out-breaks of highly pathogenic RIDs,adopting appropriate NPIs as early as possible based on their epidemiological characteristics and infection scale is necessary to minimize the harm to the population.

Objective To explore the potential influencing factors of post-operative healthcare-associated infection(HAI)in colorectal cancer patients,as well as the mediating effect relationship between the influencing factors and the diagnosis-intervention packet(DIP)payment differentials.Methods Medical data of patients who underwent colorectal cancer surgery in a tertiary first-class cancer hospital in Guangzhou were retrospectively analyzed.According to HAI status,patients were divided into infection group and non-infection group.Baseline demographic information and differences in DIP payment differentials between two groups of patients were compared by rank sum test or chi-square test.The influence of each potential factor on the occurrence of HAI was analyzed by logistic re-gression.Mediating analysis was preformed by bootstrap method,and mediating effect of HAI and total hospitaliza-tion days on DIP payment differentials was evaluated.Results A total of 350 patients were included in analysis,50 were in the infection group and 300 in the non-infection group.The incidence of HAI was 14.29％.Logistic regres-sion analysis result showed that risk of HAI in patients with central venous catheterization ≥10.00 days was 13.558 times higher than that＜10.00 days(P＜0.001);risk of HAI in patients with urinary catheterization ≥3.00 days was 2.388 times higher than that＜3.00 days(P=0.022).There were all statistically significant differences in DIP payment differentials among patients with different ages,prognostic nutritional index(PNI),HAI status,total length of hospitalization stay,duration of surgery,central venous catheterization days,and catheterization days(all P＜0.05).The mediating analysis results showed that the occurrence of HAI resulted a change in DIP payment di-fferentials by affecting the total number of hospitalization days.The mediating effect value of total hospitalization days was 0.038,accounting for 35.68％of the total effect.Conclusion Medical institutions should pay attention to HAI resulting from prolonged central venous and urinary catheterization in patients underwent surgery for colorectal cancer,reducing the total length of hospital stay,thus reducing the overruns associated with the increased DIP pay-ment differentials.

Objective:To detect the expression of angiogenic factor (AGGF1) with G-patch and FHA domain 1 in hepatocellular carcinoma (HCC), and to investigate its relationship with HCC angiogenesis, invasion and metastasis and its clinical significance.Methods:A total of 90 primary HCC patients were selected from the Huangshi Central Hospital and Hubei Province Cancer Hospital from January 2019 to September 2020. Clinicopathological data of all patients were collected. The expression of AGGF1 and CD34 in cancer tissues of 90 HCC patients was detected by immunohistochemistry, and microvascular density (MVD) was calculated. The patients were followed up for three years. The relationship between AGGF1 and serum angiopoietin-2 (Ang-2) content, MVD, clinicopathological parameters and postoperative prognosis was analyzed.Results:The positive rate, relative expression level and MVD value of AGGF1 in HCC tissues were significantly higher than those in adjacent tissues (all P<0.05). The relative expression of AGGF1 in cancer tissues was positively correlated with the MVD value ( r=0.716). Serum Ang-2 content and MVD in AGGF1-positive patients were significantly higher than those in AgGF1-negative patients (all P<0.01). AGGF1 expression in HCC tissues was significantly correlated with tumor differentiation, tumor size, (China Liver Cancer (CNLC) staging, lymph node metastasis, vascular invasion, and postoperative recurrence and metastasis (all P<0.01). Kaplan-Meier analysis showed that the 2- and 3-year survival rates of patients with high AGGF1 expression were significantly lower than those of patients with low AGGF1 expression (all P<0.01). Multivariate analysis showed that CNLC stage, lymph node metastasis, vascular invasion, AGGF1 expression, postoperative recurrence and metastasis were the influencing factors for postoperative survival of HCC patients (all P<0.05). Conclusions:The high expression of AGGF1 can promote the angiogenesis of HCC, and is significantly correlated with invasion and metastasis and poor prognosis, which can be a potential evaluation indicator of HCC clinical prognosis.
