Objective To investigate the factors affecting the hemorrhagic transformation(HT)and symptomatic intracranial hemorrhage(sICH)in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)of anterior circulation after receiving endovascular treatment(EVT).Methods A total of 193 patients with AIS-LVO of anterior circulation,who were admitted to the Neurology Department of Anyang Municipal People's Hospital of China from January 2023 to November 2024,were enrolled in this study.There were 84 patients in the HT group and 42 patients in the sICH group.The baseline and clinical data,including gender,age,vascular risk factors(history of hypertension,diabetes,coronary artery disease,atrial fibrillation,coronary stent implantation,valve replacement,smoking),stroke history,pre-operative National Institutes of Health Stroke Scale(NIHSS)scores,laboratory indicators(preoperative D-dimer,neutrophil count,lymphocyte count,postoperative total CO2,and CO2 partial pressure),and perioperative indicators(procedure duration,surgical approach,anesthesia type,and preoperative intravenous thrombolysis),were collected.The clinical data were compared between non-HT group and HT group,as well as between non-sICH group and sICH group,and the independent risk factors for HT and sICH after receiving EVT treatment for AIS-LVO of anterior circulation were analyzed.Results The differences in coronary heart disease(x2=8.443,P=0.004),D-dimer(Z=-3.59,P＜0.001),preoperative NIHSS score(Z=-3.752,P＜0.001),surgical time(Z=-2.529,P=0.011),lesion site(x2=9.951,P=0.019),and moderate to severe stenosis or occlusion of other blood vessels(P=0.025)between the HT group and the non-HT group were statistically significant.The differences in the other baseline indicators and clinical data were not statistically significant(all P＞0.05).The multivariate logistic regression analysis showed that preoperative NIHSS score(OR=1.065,95％CI:1.021-1.110,P＜0.003),tandem lesions(OR=2.805,95％CI:1.306-6.024,P=0.008),coronary heart disease(OR=2.963,95％CI:1.421-6.174,P=0.004),and operation time(OR=1.009,95％CI:1.001-1.016,P=0.019)were the independent risk factors for HT after EVT.No statistically significant differences in baseline data,occlusion site,coexisting other vascular stenosis,and perioperative related indicators existed between the sICH group and the non-sICH group.Conclusion Preoperative NIHSS score,tandem lesion,coronary artery disease,and operation time are the independent risk factors for HT in patients with AIS-LVO of the anterior circulation after receiving EVT.

Objective To explore the effect of exercise combined with dieting on chronic inflamma-tion based on fatty acids and peripheral blood mononuclear cell(PBMC)immunophenotypes.Methods Thirty-one obese volunteers(age:30.1±5.5 years,height:170.1±8.1 cm,weight:101.13±21.40 kg,BMI:34.66±5.01 kg/m2)were recruited and given a 5-week program of exercise combined with diet-ing.The exercise regimen consisted of daily 3-hour training at 60%-75%HRmax intensity,while the di-eting regimen was a moderate to high energy restriction model,with a daily reduction of 250 kcal in the 1st week and 600 kcal from the 2nd to 5th weeks.Before and after the intervention,all volunteers were measured morphological indicators(body weight,BMI,fat-free mass,body fat percentage,waist-to-hip ratio and visceral fat index),blood lipids(total cholesterol,triglycerides,high-density lipopro-tein cholesterol and low-density lipoprotein cholesterol),high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),visfatin(VF),and the content of fatty acids in the blood.Moreover,the expression of cell surface receptors CD36,TLR4,and nuclear factor-κB(NF-κB)on PBMC sub-sets was tested before and after intervention.Results After intervention,a significant decrease was ob-served in the body composition indices,as well as in the four major blood lipid parameters.Levels of chronic inflammatory markers,including hs-CRP,VF and TNF-α,decreased significantly(P<0.01).Except for C6:0,C11:0,C12:0,C23:0,and C24:0,the levels of other fatty acids also decreased sig-nificantly(P<0.05,P<0.01).Among the measured fatty acids,13,31,and 15 were found to be signif-icantly and positively correlated with hs-CRP,VF,and TNF-α,respectively(P<0.05,P<0.01).More-over,the expression of monocyte cluster of differentiation 36(CD36),Toll-like receptor 4(TLR4),and nuclear factor-κB(NF-κB)in PBMC subsets decreased significantly after the intervention(P<0.05).In lymphocytes,CD36 and TLR4 expression lowered significantly after intervention(P<0.05 and P<0.01),while in granulocytes,CD36 and NF-κB expression decreased significantly(P<0.01 and P<0.05).Conclusion Exercise combined with dietary intervention can better body composition and physi-cal function in obese individuals,alleviating their chronic inflammation.The reduction in chronic in-flammation is closely related to the decrease in circulating fatty acid levels,which results in the re-duced expression of CD36 and TLR4 receptors on the surface of PBMC and the inhibition of the NF-κB signaling pathway.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

The microbiota plays an important role in the biological functions of the human body and is associated with various disease states such as inflammation (gastritis, hepatitis) and cancer (stomach, cervical, liver). The Human Microbiome Project painted a panorama of human microorganisms in its first phase, incorporating body parts such as the nasal cavity, oral cavity, intestine, vagina and skin, while the lungs were considered a sterile environment. However, studies in recent years have confirmed the presence of a rich microbial community in the lung, and the association of this lung microbiota with lung disease has become a hot topic of research. Current research has found that patients with lung cancer have a specific microbiota compared to healthy individuals or patients with lung disease. Even in patients with lung cancer, a lung microbiota specific to the tumor site is present. In addition, different pathological types and metastatic status of lung cancer can lead to differences in microbiota. Mechanistic studies have found that the lung microbiota may influence lung cancer development by affecting the immune response. Clinical studies on lung microbiota and immunotherapy are still in the preliminary stage. More relevant studies are needed in the future to provide high-quality evidence to further understand the oncogenic mechanisms of lung microbiota and provide new ideas for clinical treatment. This paper briefly reviews the progress of lung microbiota research in terms of its relevance to lung cancer, possible molecular mechanisms and applications in clinical treatment, and provides an outlook for future research.
