The surgical treatment of thoraco-abdominal aortic aneurysm (TAAA) requires a unique multidisciplinary approach. A thorough preoperative examination and evaluation are essential to determine the optimal timing for surgery and to optimize organ function as needed. During the perioperative period, excellent surgical skills and an appropriate strategy for extracorporeal circulation will be employed based on the extent of the aneurysm. Additionally, necessary measures will be taken to monitor and protect the functions of vital organs. Close monitoring and management in the postoperative stage, along with early detection of complications and effective treatment, are crucial for improving the prognosis of TAAA surgery. This article reviews the current research progress in the perioperative management of TAAA surgery.

ObjectiveTo investigate the incidence rate of sarcopenia in patients with Wilson’s disease （WD）-related liver cirrhosis， as well as the risk factors for sarcopenia and their impact on clinical outcomes. MethodsA total of 140 patients with WD-related liver cirrhosis who were treated in The First Affiliated Hospital of Anhui University of Chinese Medicine from January 2019 to June 2020， and according to the third lumbar skeletal muscle mass index （L3 SMI）， the patients were divided into sarcopenia group and non-sarcopenia group. Nutritional risk screening， anthropometric measurements， and blood biochemical tests were performed for the patients to identify the influencing factors for sarcopenia. The patients were followed up for 36 — 48 months， and survival status and complications were compared between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the chi-square test and the Mann-Whitney U rank sum test were used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for sarcopenia， and univariate and multivariate Cox regression analyses were used to investigate the risk factors for the prognosis of patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve was plotted， and the Log-rank test was used for comparison between groups. ResultsAmong the 140 patients with WD-related liver cirrhosis， 53 （37.9%） developed sarcopenia， with significantly lower body mass index （BMI） and L3 SMI than the patients without sarcopenia （t=10.550 and 3.982， both P<0.001）. The multivariate Logistic regression analysis showed that age （odds ratio ［OR］=2.243， 95% confidence interval ［CI］： 1.196 — 4.208， P=0.012）， sex （OR=0.450， 95%CI： 0.232 — 0.872， P=0.018）， BMI （OR=0.126， 95%CI： 0.089 — 0.294， P<0.001）， and hepatic encephalopathy （OR=8.367， 95%CI： 2.423 — 28.897， P<0.001） were the main influencing factors for sarcopenia in patients with WD-related liver cirrhosis. Compared with the non-sarcopenia group， the sarcopenia group had significantly higher mortality rate （χ²=6.158， P=0.019） and significantly higher incidence rates of infection （χ²=8.008， P=0.040）， recurrent abdominal/pleural efflux （χ²=17.742， P<0.001）， and hepatic encephalopathy （χ²=4.338， P=0.039）. The multivariate Cox regression analysis showed that sarcopenia （hazard ratio ［HR］=4.685， P=0.002） and hepatic encephalopathy （HR=19.156， P<0.001） were independent risk factors for death in patients with WD-related liver cirrhosis. The Kaplan-Meier survival curve analysis showed a significant reduction in survival rate in the patients with sarcopenia （P=0.003）. ConclusionSarcopenia is one of the manifestations of malnutrition in patients with WD-related liver cirrhosis， which increases the risk of mortality and other complications and has an adverse effect on prognosis. There is an increased risk of sarcopenia in male patients or patients with hepatic encephalopathy， a lower level of BMI or an older age.

ObjectiveThis paper aims to use the digital muscle function assessment system Myoton PRO to assess the correlation between muscle tension，clinical characteristics， and traditional Chinese medicine（TCM） syndromes in patients with hepatolenticular degeneration ［also known as Wilson disease（WD）］. MethodsA total of 104 patients with WD accompanied by abnormal muscle tension（increased or decreased，hereinafter the same） who were hospitalized in the Brain Disease Centre of the First Affiliated Hospital of Anhui University of Chinese Medicine from April 2021 to November 2023 were selected，all of whom were subjected to TCM syndrome diagnosis and Myoton PRO for the measurement of F value of muscle tension，Goldstein， and UWDRS-N scales. The age of onset of the disease and disease duration were analyzed，and the differences and correlations of the above indexes in different TCM syndromes of WD were analyzed ResultsAmong the 104 patients with WD ，the phlegm and stasis syndrome was the most common（60 patients），followed by the damp-heat syndrome（33 patients），and the least common was the liver-kidney Yin deficiency syndrome（11 patients）. The F value of the phlegm and stasis syndrome group was higher than that of the liver-kidney Yin deficiency syndrome group and the damp-heat syndrome group（P<0.01）. The F value of the damp-heat syndrome group was higher than that of the liver-kidney Yin deficiency syndrome group（P<0.05），and the F value of the lower limbs of each group was higher than that of the upper limbs（P<0.01）. Goldstein and UWDRS-N scores of the patients in the phlegm and stasis syndrome group were higher than those in the damp-heat syndrome group and the liver-kidney Yin deficiency syndrome group（P<0.05）. There was no significant difference between the Goldstein and UWDRS-N scores of patients in the liver-kidney Yin deficiency syndrome group and the damp-heat syndrome group. Correlation analysis revealed that the age of onset and duration of the disease were positively correlated with the F values of the lower limbs（r=0.20，P<0.05，r=0.38，P<0.01）and had no significant correlation with those of the upper limbs. The F value levels of muscle tension of all limbs in the three groups of patients were positively correlated with the Goldstein and UWDRS-N scores（muscle tension of the upper limbs in the phlegm and stasis syndrome group，r=0.36，P<0.01，r=0.42，P<0.01. muscle tension of the lower limbs in the phlegm and stasis syndrome group，r=0.70，P<0.01，r=0.60，P<0.01. muscle tension of the upper limbs in the damp-heat syndrome group，r=0.64，P<0.01，r=0.53，P<0.01. muscle tension of the lower limbs in the damp-heat syndrome group，r=0.59，P<0.01，r=0.70，P<0.01. muscle tension of the upper limbs in the liver-kidney Yin deficiency syndrome group，r=0.70，P<0.01，r=0.74，P<0.01. muscle tension of the lower limbs in the liver-kidney Yin deficiency syndrome group，r=0.85，P<0.01，r=0.62，P<0.01）. Conlusion： The digital muscle function assessment system Myoton PRO can objectively evaluate the muscle tension level of patients with WD accompanied by abnormal muscle tension. This level has significant differences among different TCM syndromes and can evaluate the patient's condition to some extent.

Objective:To observe the effectiveness of combining mirror therapy with pneumatic flexible glove training in treating hand dysfunction after a stroke. Its effect on cerebral cortex activation was documented using near-infrared functional imaging of the brain.Methods:A total of 84 stroke survivors with hand dysfunction were randomly divided into a Mirror Group, a Glove Group and a Combined Group, each of 28. In addition to standard rehabilitation training, the Glove Group received 20 minutes of training with a pneumatic soft glove, 5 days per week for 6 consecutive weeks. The Mirror Group received mirror therapy (MT). The Combined Group was given both simultaneously. Before and after the treatment, everyone′s upper limb functioning was evaluated (using the Fugl-Meyer Upper Limb Assessment (FMA-U)), along with their hand motor skills (using the Arm Action Test (ARAT)) and their ability in daily living activities (using the Barthel Index (BI)). Functional near-infrared spectroscopy (fNIRS) was employed to measure any changes in oxygenated hemoglobin (HBO) concentration at 730nm and 850nm wavelengths.Results:The FMA-U, ATAT and BI scores in both the proximal and distal regions of all three groups showed significant improvement after the treatments compared to pre-treatment levels. The combined group demonstrated significantly better distal FMA-U and ARAT scores after the treatment (12.25±8.80 and 20.93±15.68 respectively), outperforming both the glove and mirror groups. The infrared spectroscopy revealed that bilateral SM1 activation, affected-side somatosensory association cortex (SAC) and supplementary motor cortex excitability in both the mirror and combined groups were significantly better than among the glove group after the experiment.Conclusions:Combined with pneumatic flexible glove training, mirror therapy can not only significantly improve the hand function of stroke survivors, but also activate the relevant brain regions of both hemispheres through bilateral motor patterns combined with multisensory stimulation, promoting the balance between hemispheres.

Objective:To assess the real-world triage performance of a dual-marker strategy (DMS) combining copeptin and high-sensitivity cardiac troponin T (hs-cTnT) in patients presenting with chest pain and suspected non-ST-segment elevation myocardial infarction (NSTEMI).Methods:It was conducted a prospective study of 277 consecutive chest pain patients admitted to the Emergency Department of Zhongshan Hospital, Fudan University, between July and August 2023. Admission levels of copeptin and hs-cTnT were measured. The safety, efficacy, and triage efficiency of the DMS (defined as copeptin <10 pmol/L and hs-cTnT <0.014 ng/mL) for excluding NSTEMI were evaluated based on final diagnoses and clinical outcomes.Results:Among 277 patients, 141 (50.9%) had cardiogenic diseases (51 NSTEMI, 37 unstable angina pectoris [UAP], 11 myocardial bridges, and 42 non-coronary artery disease), 29 (10.5%) had non-cardiac conditions, and 107 (38.6%) had low-risk chest pain of unknown etiology. A total of 103 patients (37.2%) were DMS-negative (copeptin and hs-cTnT both below cutoff), including 0 NSTEMI cases, 2 UAP cases, 1 myocardial bridge, 6 non-coronary artery diseases, 4 non-cardiac conditions, and 90 low-risk cases. The DMS demonstrated a negative predictive value (NPV) of 100% for excluding NSTEMI, with no major adverse cardiac events (MACE) observed in DMS-negative patients during 30-day follow-up. Real-world data revealed that only 42.2% of suspected NSTEMI patients received a second troponin test (timing: 1 hour—5.9%, 2 hours—23.9%, ≥3 hours—70.1%). The DMS enabled safe and efficient triage of 37.2% of chest pain patients at 0-hour, outperforming other strategies in applicability and feasibility ( P < 0.05). Conclusions:In real-world clinical practice, the DMS (copeptin combined with hs-cTnT) optimally complements guideline-recommended hs-cTnT algorithms. It provides a simple, rapid, and safe approach to managing acute chest pain, demonstrating superior applicability for improving emergency triage efficiency.

Cognitive dysfunction has emerged as a significant health challenge in aging societies, among which Alzheimer's disease(AD)and related dementia have become one of the leading causes of death among the elderly.These diseases are characterized by insidious onset and progressive deterioration, often reaching irreversible advanced stages at initial diagnosis, making early detection and prevention imperative.As the frontline of public health management, communities bear the responsibility for screening and managing major chronic diseases.However, community-based cognitive screening in China still remains in its nascent stages, lacking systematic management and prevention guidelines.This guideline, established under a multidisciplinary collaborative framework and adhering to evidence-based medicine principles, systematically reviews and analyzes the latest clinical evidence worldwide.Utilizing the GRADE(Grading of Recommendations Assessment, Development and Evaluation)system to evaluate evidence quality and following the RIGHT(Reporting Items for Practice Guidelines in Healthcare)statement for standardized guideline development, it ultimately presents 17 recommendations through three rounds of Delphi expert consultations.The core recommendations of this guideline is mainly to use digital cognitive scales to conduct large-scale community cognitive screening for the active individuals aged 60 or above.Stratification and staging should be performed based on screening results, and digital cognitive files with quantified risk factor grading should be established, followed by the formulation of personalized artificial intelligence(AI)prevention and control programs.This guide is the first in China and internationally to propose a quantitative grading system for low, medium, and high-risk factors associated with AD and vascular dementia(VD). It aims to provide standardized principles and practical pathways to advance China's ambitious goals: achieving ≥80% public awareness of dementia prevention knowledge, ≥80% cognitive screening rate among the elderly, ≥80% intervention guidance rate for at-risk populations, and ≥50% medical consultation rate for suspected cognitive impairment cases.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective To investigate the molecular typing,virulence,and drug resistance characteristics of Staphylococcus aureus(SA)in bone and joint infections,providing basis for anti-infection treatment.Methods The SA strains isolated from inpatients with bone and joint infections in Beijing Jishuitan Hospital,Capital Medical University from January 2014 to December 2021 were collected.Multi-locus sequence typing(MLST)and Staphylococcal A protein(Spa)typing for all the strains and Staphylococcal cassette chromo-some mec(SCCmec)typing of methicillin-resistant Staphylococcus aureus(MRSA)were performed based on whole genome sequencing.The virulence genes and drug resistance genes of the strains were identified by online database.The antimicrobial susceptibility tests were carried by automatic microbiological assay system.Results MRSA accounted for 30.0％of the 100 isolated strains of SA.A total of 22 ST types and 39 Spa types were identified in the 100 strains of S.aureus,among which ST59(16.0％)and ST239(14.0％)were the dominant ST types,and t437(13.0％)and t030(10.0％)were the dominant Spa types.ST239-SCCmecⅢ-t030/t037 clone(46.7％)was the main epidemic clone in MRSA isolates.The biofilm gene(icaA,icaB,icaC,icaD,icaR),hemolysin gene(hlb,hld,hlgA,hlgB,hlgC),adhesion gene(clfA,clfB,fnbA,fnbB,ebp),and immune escape gene(adsA,sbi,scn)were widespread in all SA strains,with detection rates ranging from 89.0％to 100.0％.The detection rates of enterotoxin genes seb(43.3％),selk(93.8％)and selq(83.3％)in MRSA were significantly higher than those in methicillin-sensitive Staphylococcus aureus(MSSA)(all P＜0.05).In terms of drug-resistance characteristics,the detection rate of the resistance gene blaZ(87.0％)was the highest among all the S.aureus strains.In the isolated MRSA strains,the detection rate of resistance genes for erm(A),tet(M),aph(3')-Ⅲ,ant(6)-Ⅰa,ant(9)-Ⅰa,and aac(6')-aph(2")ranged from 43.3％to 50.0％,which were significantly higher than those in MSSA(all P＜0.05).The results of the drug-sensitivity test showed that the resistant rates of S.aureus strains to penicillin,erythromycin,and clindamycin were relatively high(89.0％,67.0％,and 51.0％,respectively).The resistant rates of MRSA to the antimicrobial agents commonly used in clinical practice were significantly higher than those of MSSA(all P＜0.05).Conclusion The molecular epidemiological char-acteristics of SA strains isolated from bone and joint infections were diversified in our hospital.ST239-SCCmecⅢ-t030/t037 was the most common epidemic clone among the strains.There were significant differences in the resistance genes and drug resistance rates be-tween MRSA and MSSA strains,for which clinical attention should be paid.

Objective:To investigate the dietary iodine intake of students at Mudanjiang Medical University, Heilongjiang Province.Methods:From September 2023 to June 2024, a two-stage sampling method was used to investigate students at Mudanjiang Medical University. In stage one, 250 students were selected and investigated on their dietary iodine intake using the Iodine Specific Food Frequency Questionnaire (I-FFQ). In stage two, 55 students were selected and the double-meal method was used to investigate the dietary iodine intake of students. Iodine content in food samples was determined by inductively coupled plasma mass spectrometry. Curve estimation (power function, S-shaped curve, cubic equation, growth curve) was applied to analyze the dietary iodine intake of I-FFQ and double-meal method, the regression equation was used to adjust I-FFQ.Results:A total of 237 students were enrolled in I-FFQ, with a dietary iodine intake [ M( Q1, Q3)] of 342.61 (203.77, 399.26) μg/d. The dietary iodine intake of males and females was 361.82 (235.56, 428.98) and 330.87 (190.47, 366.11) μg/d, respectively, and the difference between the two was statistically significant ( Z = - 3.06, P = 0.002). The proportions of insufficient iodine intake, appropriate iodine intake, and excessive iodine intake were 13.92% (33/237), 82.70% (196/237), and 3.38% (8/237), respectively. A total of 52 students were enrolled in the double-meal method, with an average dietary iodine intake of 645.22 (435.91, 960.50) μg/d over 3 days. The proportion of appropriate iodine intake and excessive iodine intake was 44.23% (23/52) and 55.77% (29/52), respectively. After adjusting for I-FFQ, the dietary iodine intake was 650.13 (441.68, 728.53) μg/d, with the proportions of appropriate iodine intake and excessive iodine intake being 35.02% (83/237) and 64.98% (154/237), respectively. Conclusion:More than half of the students at Mudanjiang Medical University in Heilongjiang Province are in a state of excessive iodine intake, and dietary iodine intake should be appropriately controlled.
