Objective To investigate the association between the variability of remnant cholesterol inflammatory index(RCII),a novel composite biomarker,and the risk of stroke,in order to provide a theoretical basis for stroke prevention.Methods A prospective cohort study was conducted on 38 659 Kailuan individuals who took annual physical examinations in 2006,2008,and 2010.These subjects were grouped based on the quartiles of RCII variability,which was represented by standard deviation(SD)and average real variability(ARV),and were followed up every 2 years,with the occurrence of stroke(including ischemic and hemorrhagic strokes),death,or the end of follow-up on December 31,2022 as the endpoints.Kaplan-Meier method was used to calculate the cumulative incidence rate of endpoint events across different groups,and log-rank test was used to compare the difference of cumulative incidence of endpoint events in each group.Multivariate Cox proportional hazards regression model was adopted to analyze the association between RCII variability and risk of stroke.Results Among the 38 659 participants,a total of 2 539 strokes occurred during a mean follow-up period of 11.22±2.26 years.After adjusting confounding factors,when the participants were grouped by the quartiles of RCII-SD,the hazard ratio(HR)for stroke was 1.034(95%CI:0.917～1.167,P=0.584),1.146(95%CI:1.018～1.290,P=0.025),and 1.209(95%CI:1.066～1.370,P=0.003),respectively in the Q2,Q3,and Q4 groups,when compared with the Q1 group(Ptrend<0.05).When they were grouped by the quartiles of RCII-ARV,the HR for stroke was 1.008(95%CI:0.894～1.136,P=0.901),1.109(95%CI:0.986～1.248,P=0.085),and 1.152(95%CI:1.018～1.303,P=0.025),respectively,in the Q2,Q3,and Q4 groups,when compared with the Q1 group.Furthermore,both sensitivity and stratified analyses yielded similar results.Conclusion RCII variability is significantly associated with stroke,and the risk of stroke is gradually increasing with increment of the variability.Countermeasures Relevant authorities can focus on reducing RCII variability as a central objective by establishing regular monitoring mechanism,strengthening lifestyle interventions,and standardizing dietary,exercise,and weight management in order to suppress the index fluctuations.The principle of stable lipid-lowering in medication and optimization of therapeutic regimens with stable efficacy should be emphasized to prevent the risk of additional vascular damage.

Objective To explore the value of the corrected-size ratio(c-SR)value of intracranial volume computed tomography angiography(CTA)in predicting the risk of intracranial aneurysm rupture.Methods A total of 81 patients with aneurysms who had follow-up records were selected.Among them,39 patients with unruptured aneurysms and underwent regular follow-ups,while 9 patients with unruptured aneurysms opted for surgical intervention.Additionally,surgery was performed on 33 patients with ruptured aneu-rysms.Three-dimensional reconstruction of CTA was performed to obtain the morphological parameters of aneurysms.The initial size ratio(SR)value of aneurysm and the follow-up SR value or postoperative c-SR value were obtained.The changes in SR values of unruptured aneurysms were analyzed,the preoperative SR values and postoperative c-SR values of aneurysms were analyzed.Finally,the correla-tion between the intial SR value of unruptured aneurysms and the c-SR value of ruptured aneurysms was compared.Results No sig-nificant difference was observed between the initial SR value of unruptured aneurysms and the follow-up SR value(P>0.05).Simi-larly,no significant difference was noted between the preoperative SR value of unruptured aneurysms and the postoperative c-SR value(P>0.05).The preoperative SR value of ruptured aneurysms differed significantly from the postoperative c-SR value(P<0.05).There was a significant difference between the initial SR value of unruptured aneurysms and the postoperative c-SR value of ruptured aneurysms(P<0.05).The receiver operating characteristic(ROC)curve analysis was performed on the initial SR value of unrup-tured aneurysms and the postoperative c-SR value of ruptured aneurysms.The area under the curve(AUC)was 0.860 and the best cut-off value was 1.045.Conclusion Unruptured aneurysms remain stable for an extended period of time,exhibiting no significant change in morphological parameters.It can be concluded that surgical intervention does not affect the SR value of aneurysms.In the case of subarachnoid hemorrhage caused by ruptured aneurysms,the parent artery become thinner,then the preoperative SR value of ruptured aneurysms may be exaggerated,which results in the distortion of the preoperative SR value of ruptured aneurysms.However,the postoperative c-SR value is the true SR value before the rup-ture of aneurysms.

This article focuses on a case study of sitosterolemia in a child who initially presented with hemolytic anemia and thrombocytopenia. Sitosterolemia is a rare autosomal recessive lipid metabolism disorder, difficult to diagnose due to its non-typical clinical manifestations. The 8-year-old patient was initially misdiagnosed with pyruvate kinase deficiency. Comprehensive biochemical and molecular biology analyses, including gene sequencing, eventually led to the correct diagnosis of sitosterolemia. This case highlights the complexity and diagnostic challenges of sitosterolemia, emphasizing the need for increased awareness and accurate diagnosis in patients presenting with similar symptoms.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the association between internet use and healthy lifestyles in urban adults.Methods:From May to August, 2022, a face-to-face questionnaire survey was conducted in residents aged 18-64 years selected in the urban area of Hangzhou by integrated cluster stratified random sampling and Kish grid method. The information about internet use included the internet use time in the past 7 days and 12 kinds of internet use contents. Using factor analysis and K-means clustering, three types of internet use were summarized, i.e. general type, video game type and working/learning type. Healthy lifestyles were defined as active physical activity, healthy diet habit, non-smoking, non-drinking, healthy weight, and healthy waist circumference. The correlations between internet use and healthy lifestyles were evaluated by using binary logistic regression and multinomial logistic regression analyses.Results:A total of 1 624 participants were included. After adjusting for potential confounding factors, the longer internet use time group (≥8.5 h/d) was less likely to have healthy weight ( OR=0.59, 95% CI:0.41-0.85) and 5-6 healthy lifestyles ( OR=0.55, 95% CI: 0.32-0.96) compared with those with shorter internet use time group (<2.5 h/d). For different types of internet use, it was found that compared with working/learning type group, the general type group was less likely to have healthy diet habits ( OR=0.63, 95% CI: 0.46-0.86), non-drinking ( OR=0.68, 95% CI: 0.47-0.99), healthy waist circumference ( OR=0.59, 95% CI: 0.42-0.84) and 5-6 healthy lifestyles ( OR=0.40, 95% CI: 0.23-0.69), the video game type group was less likely to have active physical activity ( OR=0.73, 95% CI: 0.55-0.97) and healthy diet habits ( OR=0.79, 95% CI: 0.62-0.99). Conclusion:Too long internet use (≥8.5 h/d), general type and video game type of internet use were associated with unhealthy lifestyles.

Objective:To explore differences of resting brain regional homogeneity (ReHo) between patients with major depressive disorder (MDD) and their siblings.Methods:From January to December 2013, the resting-state functional magnetic resonance imaging (fMRI) data of 87 patients with MDD and 21 healthy siblings were collected.DPABI v5.1 software was used to preprocess the resting-state fMRI data, and ReHo maps of each subject was obtained. A two-sample t-test was used to compare differences between the patients with MDD and their siblings in ReHo values throughout the brain. ReHo values within the significant brain regions were extracted out, and used to calculate Spearman correlation with the total score of 17-items Hamilton depression rating scale(HAMD-17) in the patients with MDD and their siblings respectively.The software of SPSS 20.0 was used for statistical analysis. Results:The patients with MDD exhibited lower ReHo values in the precuneus extending to the posterior cingulate cortex (PCu/PCC) compared with their siblings (cluster-size=126 voxel, cluster-level PFDR=0.033; MNI: x=-4, y=-58, z=38, t=4.30). ReHo values of the PCu/PCC in patient with MDD were positively correlated with the severity of depressive symptoms ( r=0.255, P=0.021). Conclusion:Compared with the siblings, local brain activity of the PCu/PCC in the patients with MDD was decreased, and related to the severity of depressive symptoms. It is helpful to further reveal the intrinsic neural mechanism of MDD.
