Objective:This study aims to investigate the differences in emotional status and cognitive function among patients with vestibular migraine (VM), Meniere′s disease (MD), and their comorbidity (VMMD), and to analyze key factors influencing cognitive function.Methods:This cross-sectional study included 96 outpatients (32 males, 64 females, aged 21-73 years) from the Department of Otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, between December 2022 and December 2023. The study population consisted of 31 VM patients (VM group), 36 MD patients (MD group), and 29 VMMD patients (VMMD group), along with 32 healthy controls (16 males, 16 females, aged 19-74 years). Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), while emotional status and somatization symptoms were evaluated through the Generalized Anxiety Disorder scale, Patient Health Questionnaire Depression scale, Symptom Checklist-90, and the Self-rating Somatization Symptom scale. Multiple linear regression analysis was conducted to explore the influence of different variables on cognitive function.Results:The total MoCA score in the VMMD group (26.0 [24.5, 28.0]) was significantly lower than that in the control group (28.0 [27.0, 29.0]) and the MD group (28.0 [26.0, 30.0]) ( P=0.006). VMMD patients exhibited significant impairments in specific cognitive domains, including visuospatial/executive function, delayed recall, and orientation ( P<0.05). Patients with VM, MD, and VMMD showed higher rates of anxiety, depression, and somatization symptoms compared to the control group ( P<0.05), with the VMMD group experiencing the most severe emotional distress. Multiple linear regression analysis identified education level and vestibular disease type as key factors affecting cognitive function, with a university-level education predicting higher MoCA scores ( P<0.001), while VMMD was associated with cognitive decline ( P<0.01). Conclusions:Patients with VM and MD, particularly those with comorbid VMMD, exhibit significant emotional distress. Cognitive impairments are present in VM and VMMD patients, affecting different cognitive domains. These factors should be comprehensively considered in clinical assessments to develop more effective treatment strategies.

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 evaluate the value of 3T magnetic resonance imaging (MRI) in the preoperative T staging of potentially resectable esophageal cancer(EC), compared with endoscopic ultrasonography (EUS). Methods Patients with resectable EC pathologically confirmed by biopsy from March 2015 to September 2016 were prospectively enrolled. All patients underwent MRI (including T2-TSE-BLADE,DWI and radial-VIBE)and EUS one week after the biopsy,and MRI were performed prior to EUS, both MRI and EUS were acquired within one week before surgery. Two readers with more than 5 years experiences in the MRI diagnosis evaluated the MR image quality using a 5-point score independently. T staging was assigned on MRI and EUS by the two MRI readers using double-blind method and one endoscopist in accordance with the 7th edition of AJCC TNM Classification for EC, and any disagreement between two MRI readers was resolved by consensus with discussion to the third senior MRI doctor. The inter-observer agreement between two MRI readers were calculated using Kappa test for image quality scores and T staging results. Considering postoperative pathological T staging results as the gold standard, the performances of MRI and EUS were evaluated based on the accuracy rate and analyzed by χ2 test. Results A total of 70 patients were enrolled in the study, the good image quality cases (≥ 3 scores) were 66 in reader 1 and 68 in reader 2. The inter-observer agreement of the image quality scores by two readers was excellent (Kappa=0.824, P<0.05). The pathological results revealed 16 cases of T1 stage, 18 cases of T2 stage, 30 cases of T3 stage, and 6 cases of T4a stage. The inter-observer agreement of the preoperative T staging of EC by two readers was excellent (Kappa=0.809, P<0.05). The accuracy rates of MRI and EUS for preoperative T staging of EC were 92.9% (65/70) and 67.1% (47/70), respectively, and the difference in accuracy rates of two techniques was statistically significant (χ2=14.5, P<0.05). Conclusions The accuracy rate of MRI for preoperative T staging of EC is significantly higher than that of EUS. MRI can be used as a noninvasive method for preoperative T staging of EC.

Objective To explore the feasibility of evaluating cardiac structure, coronary artery,pulmonary artery and cardiac function in one single scan by 320-row CT ECG-gated double phase cardiac function scan mode. MethodsForty patients underwent the 320-detector row CT double phase cardiovascular angiography. The pulmonary phase and aortic phase were reconstructed in order to evaluate the pulmonary and coronary artery. MPR reconstructions of both pulmonary and aortic phase were used to analyze the function of the two ventricles. And the results of the cardiac function were compared with those of transthoracic echocardiography. Thirty-five cases could be analyzed and diagnosed, while the other 5 cases had to be given up because of the poor imaging quality. The mean heart rate was (71.2 ± 11.2) beat per min (bpm). No arrhythmia case included. Results ( 1 ) Pulmonary embolism were diagnosed in 11 cases,coronary artery disease (CAD) were found in 5 cases, while post-stent implantation were observed in 7 cases. Six cases of congenital heart disease were diagnosed with 3 ASD and 3 primary pulmonary hypertension. Another one was diagnosed with left atrial myxoma, and 5 cases were pulmonary embolism associated with CAD. All of above cases were verified by final clinical diagnosis. (2) The heart function parameters including LVEDd , RVEDd, LVESd, RVESd and LVEF were (36.7 ±3.3), (43.3 ± 3.4) mm,(31.6±5.1), (41.3 ±5.1) mm and (47.1 ±15.1) for CT, while those were (40.3 ±3.1), (47.3 ±4.2) mm,(37.3 ±5.6), (45.3 ±3.3) mm,and (46.0 ± 14.8) for ultrasound, respectively. The CT results were correlated with the ultrasound ( n = 35, r = 0.886-0.988, P ＜ 0.01 ). (3) The average radiation exposure was ( 5.4 ± 0.5 ) mSv. Conclusions 320-row CT ECG-gated double phase cardiac function scan mode is feasible for the "one-stop-shop" examination of the cardiovascular disease. This noninvasive method is recommended for the diagnosis, differential diagnosis, treatment and prognosis of cardiovascular disease.

Objective To evaluate the combination of dual-energy CT angiography (DE-CTA) and dual-energy CT peffusion (DE-CTP) in the diagnosis of coronary artery disease. Methods Thirty-one patients with angina pectoris were examined using dual-source dual energy CT and conventional coronary angiography. For DE-CTA, we used a contrast-enhanced ECG-gated coronary scan protocol with energy levels of two tube detector arrays at 140 and 100 kVp. Two kinds of acquired images were fused for the CT angiogram and further calculated to construct a perfusion map (Siemens DE Heart PBV). The compared the following results: DE-CTA vs. CA, DE-CTP vs. CA to assess the sensitivity and specificity, and further compared DE-CTA plus DE-CTP with CA. Results DECT obtained diagnostic image quality in 28 patients.DE-CTA detected 41/112 arterial stenosis. Using CA as a reference, the sensitivity of DE-CTA was 81%(38/47), specificity was 95% (62/65), positive predictive value was 92% (38/41), negative predictive value was 87% (62/71), and accuracy was 89% (100/112). DE-CTP detected 46 perfusion defects in artery territories. Using CA as a reference, the sensitivity of DE-CTP was 76% ( 36/47), specificity was 85% (55/65), positive predictive value was 78% (36/46), negative predictive value was 83% (55/66),and accuracy was 81% (91/112). DE-CTA plus DE-CTP diagnosed 52 arteries stenosis. Using CA as a reference, combination of DE-CTA and DE-CTP gave sensitivity of 95% ( 45/47 ), specificity of 89%(58/65) , NPV of 97% (58/60), and accuracy of 92% (103/112). Conclusions DECT can provide perfusion blood volume information as well as vessel pathology in one scan. DECT can provide comprehensive diagnosis and improve diagnosis of CAD.

ObjectiveAnalyzing the left atrium and pulmonary vein morphologicallv by 64 multislice spiral CT(MSCT)scan to guide the catheter ablation of Atrial fibrillation.MethodsTwo hundred and thirty-two patients(146 cases in atrial fibrillation group and 86 cases in control group)received 64 MSCT examination of the left atrium and pulmonary vein.The incidence of anatomical variation of pulmonary vein was compared between atrial fibrillation group and control group. For each group,the anatomical morphology ot every pulmonary vein and the auricle of left atrium was analyzed, the diameter of the orifice of each pulmonary vein and the size of left atrium were measured.ResultsSixty-four MSCT of left atrium and pulmonary vein could demonstrate detailed connecting type between left atrium and pulmonary Veins and the possible anatomieal variation. Anatomical variation of pulmonary vein in this study accounted for 16.8% (39/232)of total sample. For both groups,orifices of pulmonary veins appeared oval and their superoinferior diameters were larger than their anteroposterior diameters. There was significant difference in the inner diameter of left atrium between atrial fibrillation group and control group[atrial fibrillation group:(39.47±8.98)mm,control group:(36.94 ±5.49)mm,P=0.02],while there was no difference in the diameters of orifices ot puhnonary veins between two groups [ superoinferior diameters of pulmonary veins in atrial fibrillation group:left-up(18.15±1.35)mm,left-down(16.96 ±1.18)mm,right-up(17.50±
