Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

In the context of the complex and ever-changing spectrum of diseases, the traditional Chinese medicine compatibility of prescription and drugs is no longer able to fully meet the needs of clinical diagnosis and treatment. Therefore, this article is based on the diagnosis and treatment model of the combination of disease, syndrome, and symptom, combined with the development achievements of Western medicine, and explores the principles of formulating traditional prescriptions based on the combination of chief, deputy, assistant, and envoy. This article proposes a formulation principle of composing prescriptions with the diagnosis of syndrome as the chief, the diagnosis of disease as the deputy, the treatment of symptoms as the assistant, and the harmonization of medicine as the envoy. This forms a treatment plan with the core link of syndrome differentiation and treatment, disease differentiation and treatment, symptomatic treatment, detoxification, and efficacy enhancement. The purpose of this article is to address the current clinical challenges such as an increasing disease spectrum and the complexity of syndrome patterns and symptom clusters. It aims to provide new insights into traditional Chinese medicine clinical treatment plans and herbal formulation strategies, with the ultimate goal of improving the clinical effectiveness of traditional Chinese medicine.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

Objective:To discuss the effect of Aspergillus fumigatus(Af)on DNA damage and interleukin(IL)-33 expression in the human bronchial epithelial cells,and to clarify its related mechanism.Methods:Different concentrations(1,5,and 10 mg·L-1)of Af were used to stimulate the bronchial epithelial BEAS-2B cells to select the appropriate stimulation concentration.When the BEAS-2B cells were treated with N-acetylcysteine(NAC)and Af,the cells were divided into control group,Af group,NAC group,and Af+NAC group.When the BEAS-2B cells were treated with DNA double-strand break repair inhibitor NU7441 and Af,the cells were divided into control group,Af group,NU7441 group,and Af+NU7441 group.The comet assay was used to detect the percentages of comet tail DNA of cells in various groups;immunofluorescence method was used to detect the expression levels of DNA damage-related protein phosphorylated H2AX(yH2AX)in the cells in various groups;2,7-dichlorofluorescein diacetate(DCFH-DA)fluorescence probe was used to detect the levels of reactive oxygen species(ROS)in the cells in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of interleukih-33(IL-33),thymic stromal lymphopoietin(TSLP),and interleukih-25(IL-25)mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of phosphorylated nuclear factor κB(p-NF-κB),phosphorylated ataxia telangiectasia mutated(p-ATM),and γH2AX proteins in the cells in various groups.Results:Compared with control group,the percentage of comet tail DNA and the expression level of γH2AX in the cells in 1 mg·L-1 Af group showed no significant difference(P＞0.05),while the percentage of comet tail DNA and the expression level of γH2AX in the cells in 5 mg·L-1 Af group were significantly increased(P＜0.01);compared with 5 mg·L-1 Af group,the percentage of comet tail DNA and the expression level of γH2AX in the cells in 10 mg·L-1 Af group were significantly increased(P＜0.01).Compared with control group,the ROS levels in the bronchial epithelial cells in 1 mg·L-1 Af group was significantly increased(P＜0.05);compared with 1 mg·L-1 Af group,the ROS level in the cells in 5 mg·L-1 Af group was significantly increased(P＜0.01);compared with 5 mg·L-1 Af group,the ROS level in the cells in 10 mg·L-1 Af group was significantly increased(P＜0.05).After treatment of NAC,compared with Af group,the percentage of comet tail DNA(P＜0.01),the expression level of γH2AX(P＜0.05),and the ROS level(P＜0.01)in the cells in Af+NAC group were significantly decreased;after treatment of NU7441,compared with Af group,the percentage of comet tail DNA and the expression level of yH2AX in the cells in Af+NU7441 group were significantly increased(P＜0.01).The RT-qPCR results showed that after treatment of NAC,compared with control group,the expression level of IL-33 mRNA in the cells in Af group was significantly increased(P＜0.05);compared with Af group,the expression level of IL-33 mRNA in the cells in Af+NAC group was significantly decreased(P＜0.05);after treatment of NU7441,compared with Af group,the expression level of IL-33 mRNA in the cells in Af+NU7441 group was significantly increased(P＜0.05).The Western blotting results showed that after treatment of NAC,compared with control group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af group were significantly increased(P＜0.05);after treatment of NU7441,compared with Af group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af+NAC group were significantly decreased(P＜0.05);After treat ment of NU7441,compared with Af group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af+NU7441 group were significantly increased(P＜0.05).Conclusion:Af promotes the IL-33 expression in the human bronchial epithelial cells by causing DNA damage,and its mechanism may be related to the activation of ATM/NF-κB signaling pathway.

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.
