Objective To investigate the post-discharge exercise behavior and factors influencing moderate to vigorous intensity physical activity (MVPA) in patients undergoing lung surgery. Methods A total of 2874 patients from the large prospective, observational perioperative lung symptom study cohort (CN-PRO-Lung 3) in the Department of Thoracic Surgery at Sichuan Cancer Hospital between April 7, 2021, and January 31, 2024, were selected as the survey subjects. A survey was conducted using the Investigation of Exercise Behavior after Lung Surgery questionnaire and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) among patients who underwent lung surgery. Binary logistic regression was used to analyze the factors influencing patients’ engagement in MVPA. Results A total of 702 patients were surveyed, including 252 males and 450 females, with an average age of (52.4±10.2) years. Patients with lung cancer accounted for 85.9%. Only 36.0% of the patients had regular exercise habits, while 42.3% did not engage in any physical activity. The three main barriers for postoperative exercise were physical discomfort (pain, coughing, shortness of breath, etc, 54.7%), lack of professional guidance (41.7%), and concerns about the surgical wound (28.9%). The proportions of patients engaging in vigorous, moderate, and low-intensity physical activity were 5.7%, 28.2%, and 66.1%, respectively. Multivariate analysis showed that patients with a personal annual income ≥50000 yuan (OR=1.52, 95%CI 1.01-2.29, P=0.044), high school education or above (OR=1.92, 95%CI 1.33-2.76, P<0.001), and lobectomy (OR=1.44, 95%CI 1.02-2.03, P=0.037) engaged in more MVPA. Conclusion Patients undergoing lung surgery have inadequate physical activity after discharge, particularly lacking in MVPA. Patients with higher income, higher educational levels, and lobectomy are more frequently engaged in MVPA. Measures such as symptom control, providing exercise guidance, and enhancing education on wound care may potentially improve the inadequate physical activity in lung surgery patients after discharge.

Objective:To understand the management of children with pediatric acute liver failure (PALF) in pediatric intensive care unit (PICU).Methods:A retrospective case-control study was conducted. A total of 101 children with PALF hospitalized in PICU of Beijing Children′s Hospital from July 2017 to October 2022 were included. Demographic, clinical management and prognosis data were collected. According to whether PALF was the main diagnosis, the patients were divided into primary diagnosis group and complication group. The primary diagnosis group was subdivided into effective group and ineffective group with routine treatment (except liver transplantation). The intergroup comparisons were performed using independent samples t-test, Mann-Whitney U test, χ2 test or Fisher exact test. Multivariate Logistic regression analysis was employed to identify risk factors associated with prognosis. Results:Among the 101 children with PALF, 58 were male and 43 were female, with an age of 30 (10, 103) months, 60 cases in primary diagnosis group and 41 cases in complication group. There were no significant differences in prothrombin time (PT) and international normalized ratio (INR) between the two groups (both P>0.05), while the total bilirubin, direct bilirubin and blood ammonia were all significantly higher in the primary diagnosis group (all P<0.05). Unoriginal liver failure (25 cases (42%)) and poisoning (13 cases (22%)) were the most common causes of PALF in the primary diagnosis group, while shock (17 cases, 43%) and hemophagocytic syndrome (14 cases (34%)) in the complication group. The mortality rate of the main diagnosis group was significantly lower than that of the complication group (25% (15/60) vs. 61% (25/41), χ2=13.18, P<0.001), as well as the incidence of combined organ function injury, while the amount of plasma used and the ratio of plasma exchange times to PICU hospitalization days were significantly higher (all P<0.05). In the primary diagnosis group, there were 32 cases (53%) in the effective group and 28 cases (47%) in the ineffective group. In the ineffective group, 15 cases (54%) died and 13 cases (46%) were transferred to another site for liver transplantation assessment. The hospitalization time of PICU in the effective group was significantly longer than that in the ineffective group, while the ratio of plasma exchange times to PICU hospitalization days, the average daily hours of continuous renal replacement therapy (CRRT), the rate of CRRT and the average daily plasma dosage in the effective group were all significantly lower than those in the ineffective group (all P<0.05). The worst PT, INR and blood ammonia, and the stage 4 hepatic encephalopathy morbidity and significant bleeding rate in the effective group were all significantly lower than those in the ineffective group (all P<0.05). Multivariate Logistic regression analysis showed that after adjusting for age, sex, total bilirubin, INR and blood ammonia, stage 4 hepatic encephalopathy was the independent risk factor for the failure of routine treatment of PALF ( OR=84.16,95% CI 4.04-1752.37, P=0.004). Conclusions:PT and INR could not specifically represent liver synthetic function in some PICU patients, so current PALF diagnostic criteria for PICU children has limitations. Complicated with stage 4 hepatic encephalopathy was an independent risk factor of the failure of conventional treatment in patients with PALF.

Objective:To compare the efficacy of Ilizarov ring external fixation and unilateral rail external fixation in the treatment of infected bone defects following surgery for tibial fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 50 patients with infected bone defects after surgery for tibial fractures, who were admitted to the 940th Hospital of the Joint Logistics Support Force of the PLA from August 2019 to November 2021, including 37 males and 13 females, aged 19-59 years [(42.2±8.8)years]. After debridement and osteotomy, 28 patients were treated with Ilizarov ring external fixation (Ilizarov group) and 22 with unilateral rail external fixation (unilateral fixation group). All the patients in the two groups had previously undergone internal fixation with plates or Kirschner wires for tibial fracture before bone transport. Bone transport started at one week for three stages after successful infection control and osteotomy and was conducted. The following parameters were compared between the two groups: frame-wearing time and healing index after bone transport, self-rating anxiety scale (SAS) grade at 6 months after bone transport, Paley score and Association for the Study and Application of the Method of Ilizarov (ASAMI) score at the last follow-up, Hospital for Special Surgery (HSS) knee score and Baird-Jackson ankle score on admission, after external fixator removal and at the last follow-up, and incidence of postoperative complications.Results:All the patients were followed up for 28-36 months [(32.5±1.6)months]. There were no significant differences in frame-wearing time or healing index between the two groups after bone transport ( P>0.05). At 6 months after bone transport, the SAS grade in the unilateral fixation group (13 patients with mild anxiety, 8 with moderate anxiety, and 1 with severe anxiety) was better than that in the Ilizarov group (6 patients with mild anxiety, 19 with moderate anxiety, 3 with severe anxiety) ( P<0.01). No significant differences were found in the Paley score or ASAMI score between the two groups at the last follow-up ( P>0.05). There were no significant differences in HSS knee score or Baird-Jackson ankle score between the two groups on admission, after external fixator removal or at the last follow-up ( P>0.05). No significant differences were observed in the incidence of pin tract infection, poor healing, infection in the bone elongation area, or re-fracture between the two groups ( P>0.05). The incidence of postoperative axial deviation was 0 in the Ilizarov group, lower than 18% in the unilateral fixation group (4/22) ( P<0.05). Conclusion:Although Ilizarov ring external fixation and unilateral rail external fixation demonstrate comparable efficacy in the treatment of infected bone defects after surgery for tibial fractures, the former provides superior mechanical stability and postoperative axial deviation correction, while the latter offers advantages in reducing psychological burden and enhancing treatment tolerance.

Objective:This study aimed to validated the diagnostic accuracy of Global Leadership Initiative on Malnutrition(GLIM)criteria for malnutrition in pancreatic cancer patients undergoing pancreaticoduodenectomy and to evaluated its prognostic value for postoperative outcome.Methods:A retrospective analysis was conducted on 230 consecutive pancreatic cancer patients who underwent pancreaticoduodenectomy at the Department of Pancreatobiliary Surgery,Sun Yat-sen University Cancer Center,between January 2018 to January 2024.Patients were stratified into malnutrition group and non-malnutrition group using Nutritional Risk Screening 2002(NRS 2002)and GLIM criteria.Multivariable logistic regression identified independent risk factors for postoperative morbidity.Results:GLIM criteria identified malnutrition in 96 patients(41.7％).Compared with the non-malnourished group,the number of preoperative nutritional support(t=20.038,P<0.001),the number of preoperative enteral nutrition support(t=8.377,P=0.004),the number of preoperative parenteral nutrition support(t=22.302,P<0.001),the number of anemia(t=8.037,P=0.005)and preoperative parenteral nutrition use days(t=-2.898,P=0.009),the difference was statistically significant.There were statistically significant differences in C-reactive protein(t=10.944,P=0.008),NLR(t=-2.523,P=0.012)and PNI(t=-2.397,P=0.017)between the two groups before surgery.Preoperative BMI(t=-4.410,P<0.001)was significantly lower in the malnourished group.The number of postoperative parenteral nutrition days(Z=-2.283,P=0.022)and amino acid supplementation during postoperative hospitalization were significantly higher in the malnourished group(Z=-2.309,P=0.021).The incidence of malnutrition was higher in patients with Clavien-Dindo grade≥Ⅲ(P=0.030)and intra-abdominal infections(P=0.049).Multivariable analysis identified preoperative weight loss(OR=2.154,95％CI:1.158～4.005;P=0.015)and BMI reduction(OR=0.175,95％CI:0.040～0.775;P=0.022)as independent predictors of postoperative complications.Conclusions:The GLIM standard effectively characterize malnutrition status in pancreatic cancer patients after pancreaticoduodenectomy patients and demonstrate superior predictive performance for postoperative morbidity.It has good predictive performance and clinical application value.

Objective To analyze the distribution of serum food specific immunoglobulin(Ig)E and IgG antibodies in patients with adverse food reactions in Qingdao area.Methods The specific IgE test results of 4 199 patients with suspected food allergy and the specific IgG test results of 741 patients with food intoler-ance were collected from the Affiliated Hospital of Qingdao University from 2012 to 2022.A total of 4 199 pa-tients with suspected food allergy(2 308 males and 1 891 females)were enrolled in this study.According to the age,the patients were divided into infancy(＜1 year old)205 cases,early childhood(1-＜3 years old)1009 cases,childhood(3-＜14 years old)1 946 cases,adolescence(14-＜18 years old)99 cases,youth(18-＜40 years old)554 cases,middle age(40-＜65 years old)329 cases and old age(≥65 years old)57 cases.A to-tal of 741 patients with food intolerance(469 males and 272 females)were enrolled in this study.According to the age,the patients were divided into 81 cases in infancy(＜1 year old),298 cases in early childhood(1-＜3 years old)and 362 cases in childhood(3-＜14 years old).Enzyme-linked immunosorbent assay was used to detect the positive rates of IgE and IgG antibodies in serum of patients,and the positive rates of IgE and IgG antibodies in patients with different gender and age were compared.Results Egg white and cow's milk were the most sensitive foods in infants and young children.The positive rate of specific IgE antibody decreased gradually with the increase of age,and increased slightly in old age.The positive rate of specific IgE antibody in shrimp and crab increased first and then decreased with age,and it was higher in young and middle age.The tolerance of infants and children to meat and crustaceans was relatively strong,and the positive rate of food specific IgG to fish was higher than that to meat(P＜0.05).The positive rate of tomato-specific IgG was the highest in infancy and gradually decreased with age(P＜0.05).Conclusion With the increase of age and the change of dietary structure,the positive rate of food specific IgG antibody may change significantly.Clinicians should accurately grasp the epidemiological characteristics of food adverse reactions in this area,and adjust and optimize the diet structure of patients to make correct diagnosis and treatment.

OBJECTIVE: To explore the effect of acupuncture therapy on dysphagia in patients with Parkinson's disease. METHODS: This randomized controlled study lasted 42 days and included 112 patients with Parkinson's disease and dysphagia. Participants were randomly assigned to the experimental and control groups (56 cases each group) using the completely randomized design, all under routine treatment. The experimental group was given acupuncture therapy. The primary outcome was Penetration-Aspiration Scale (PAS). The secondary outcomes were (1) Standardized Swallowing Assessment (SSA), and (2) nutritional status including body mass index (BMI), serum albumin, prealbumin, and hemoglobin. Adverse events were recorded as safety indicators. RESULTS: One participant quitted the study midway. There were no significant differences in baseline assessment (P>0.05). After treatment, both groups showed significant improvement in PAS, SSA and nutritional status except for BMI of the control group. There were significant differences between the two groups in the PAS for both paste and liquid, SSA (25.18±8.25 vs. 20.84±6.92), BMI (19.97±3.34 kg/m²vs. 21.26 ±2.38 kg/m²), serum albumin (35.16 ±5.29 g/L vs. 37.24 ±3.98 g/L), prealbumin (248.33 ±27.72 mg/L vs. 261.39 ±22.10 mg/L), hemoglobin (119.09±12.53 g/L vs. 126.67±13.97 g/L) (P<0.05). There were no severe adverse events during the study. CONCLUSION: The combination of routine treatment and acupuncture therapy can better improve dysphagia and nutritional status in patients with Parkinson's disease, than routine treatment solely.

Stroke is a critical health issue in China, and carotid artery stenosis and plaque play key roles in its prevalence. Despite the acknowledged significance of this condition, detailed information regarding the prevalence of carotid artery stenosis and plaque across the Chinese population has been scarce. This study analyzed data from the China Stroke High-risk Population Screening and Intervention Program for 2020-2021, focusing on 194 878 Chinese adults aged 40 years and above. It assessed the prevalence of carotid artery stenosis and plaque and identified their associated risk factors. Results revealed a standardized prevalence of 0.40% for carotid artery stenosis and 36.27% for carotid plaque. Notably, the highest rates of stenosis were observed in north and south China at 0.61%, while southwestern China exhibited the highest plaque prevalence at 43.17%. Key risk factors included older age, male gender, hypertension, diabetes, stroke, smoking, and atrial fibrillation. This study highlights significant geographical and demographic disparities in the prevalence of these conditions, underlining the urgent need for targeted interventions and policy reforms. These measures are essential for reducing the incidence of stroke and improving patient outcomes, addressing this significant health challenge in China.

Ferroptosis is a programmed cell death depends on iron and lipid peroxidation,which has been recognized as the key pathogenic factor for the occurrence of various diseases in recent years,especially playing a significant role in neurodegenerative diseases.Ferroptosis triggers lipid peroxidation and oxidative stress in neuronal cells,leading to neuronal damage and death,thereby accelerating disease progression.Hydrogen sulfide,as an endogenous gaseous signaling molecule,exhibits multiple protective effects,including anti-inflammatory,antioxidant,and anti-ferroptosis properties.Hydrogen sulfide can effectively inhibit the occurrence of ferroptosis through various mechanisms,such as regulating iron metabolism,inhibiting lipid peroxidation,and enhancing the activity of antioxidant enzymes,thereby slowing down the progression of neurodegenerative diseases.This article reviews the related research progress on hydrogen sulfide and ferroptosis and ferroptosis-mediated neurodegenerative diseases,and analyzes the underlying mechanisms,aims to provide new insights and theoretical foundations for the treatment of neurodegenerative diseases.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."
