This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

Objective:To investigate the correlation between plasma fibrinogen/serum albumin ratio (FAR) and the degree of cerebral artery stenosis in patients with acute cerebral infarction (ACI).Methods:Clinical data of 189 patients with acute cerebral infarction diagnosed and treated in the Department of Neurology of the First Affiliated Hospital of Hainan Medical College from January 2021 to March 2023 were selected for retrospective analysis. Digital subtraction angiography (DSA) was improved, and they were divided into four groups according to the degree of intracranial vascular stenosis according to NASCET grading method: no stenosis group (47 cases), mild stenosis group (45 cases), moderate stenosis group (39 cases) and severe stenosis and occlusion group (58 cases). The differences of basic data, plasma fibrinogen/serum albumin ratio (FAR) and other inflammatory indicators among all groups were compared, and the correlation between FAR level and the severity of cerebral artery stenosis was analyzed. Multivariate Logistic regression was used to explore the factors influencing to cerebral artery stenosis and ROC curve was used to evaluate the diagnostic value of FAR in the degree of cerebral artery stenosis in cerebral infarction patients.Results:There were significant differences in blood neutrophil (NEU), mean platelet volume (MPV), fibrinogen (FIB), fibrinogen (FIB), albumin (ALB) and FAR among the 4 groups (statistical values were H=11.50, H=8.44, F=5.16, H=30.93, H=40.38; all P<0.05). Correlation analysis showed a positive correlation between FAR and the degree of cerebral artery stenosis ( r=0.455, P<0.05). Multivariate Logistic regression showed that FAR was an independent risk factor for the degree of cerebral artery stenosis ( OR=1.445, 95% CI=1.261-1.655, P<0.001). Conclusion:FAR is an independent risk factor for cerebral artery stenosis in patients with acute cerebral infarction (ACI), and may be a new biomarker for predicting cerebral artery stenosis.

Chronic internal carotid artery occlusion, a common clinical lesion caused by atherosclerosis, was also one of the common vascular diseases in the middle and old age. It could slow down the blood flow rate of blood vessels, which leaded to changes in the blood supply of brain tissue, and secondary causes abnormal metabolism of brain nerves and brain tissue. At the same time, long-term cerebral hypoperfusion would induce cognitive impairment, which would seriously affect the quality of life of patients. At present, there were two main treatment methods: drug conservative treatment and intravascular intervention, but there was still a great controversy about the survival of the fittest in these two treatment methods. This paper reported the clinical, imaging, therapeutic strategy and prognosis of a case of severe intracranial and extracranial multiple vessel stenosis and occlusion, in order to provide reference for the early diagnosis and treatment of such patients.

Objective:To evaluate the right ventricular function in patients with dilated cardiomyopathy (DCM) by four-dimensional automatic right ventricular quantitative analysis (4D Auto RVQ), and compare with the right ventricular ejection fraction measured by cardiac magnetic resonance (CMR-RVEF), and to explore the clinical application value of 4D Auto RVQ technique in evaluating the right ventricular function of patients with DCM.Methods:A prospective study was conducted to select 52 patients with DCM who were treated in Fuwai Central China Cardiovascular Hospital of Zhengzhou University from March to October 2022 as DCM group, and 52 healthy volunteers were selected as the control group during the same period. The four-dimensional right ventricular ejection fraction (4D-RVEF), right ventricular stroke volume index (RVSVI), right ventricular end-diastolic volume index (RVEDVI), right ventricular end-systolic volume index (RVESVI), four-dimensional right ventricular basal diameter (4D-RVDd-base), four-dimensional right ventricular middle diameter (4D-RVDd-mid), four-dimensional right ventricular long axis diameter (4D-RVLd), four-dimensional tricuspid annular plane systolic excursion (4D-TAPSE) and four-dimensional right ventricular fractional area change (4D-RVFAC) were obtained by 4D Auto RVQ technique. The differences of the above parameters between DCM group and control group were compared.Pearson linear correlation analysis was used to evaluate the correlation between echocardiographic parameters and CMR-RVEF. The ROC curve was used to find the most sensitive parameters for evaluating right ventricular function, and the area under the ROC curve ( AUC ) was calculated and compared.Results:Compared with the control group, RVEDVI, RVESVI, 4D-RVDd-base and 4D-RVDd-mid in the DCM group were increased, and the absolute values of 4D-RVEF, 4D-TAPSE, 4D-RVFAC, right ventricular global longitudinal strain(RVGLS) and right ventricular free wall longitudinal strain(RVFWLS) were decreased (all P<0.05). Correlation analysis showed that 4D-RVEF was positively correlated with CMR-RVEF ( r=0.711, P<0.05). ROC curve analysis showed that 4D-RVEF was superior to other parameters in evaluating right ventricular function in DCM patients (AUC: 0.916). Conclusions:4D Auto RVQ technique can quantitatively evaluate right ventricular function in DCM patients. 4D-RVEF has a significant correlation with CMR-RVEF, and 4D-RVEF has the best efficacy in evaluating right ventricular function in DCM patients.

Objective:To evaluate left atrial(LA) function and its value in predicting left ventricular(LV) remodeling in patients with coronary heart disease (CHD) by four dimensional automatic left atrial quantitation (4D Auto LAQ).Methods:A total of 176 patients with CHD were prospectively enrolled in Fuwai Central China Cardiovascular Hospital from October 2021 to September 2022. They were divided into two groups according to left ventricular mass index: LV remodeling group (female>95 g/m 2, male>115 g/m 2, n=88) and Non-LV remodeling group (female≤95 g/m 2, male≤115 g/m 2, n=88). The 3D dynamic image of LA was analyzed by 4D Auto LAQ on machine to obtain the LA parameters, including the minimum, maximum, pre-systolic and emptying volumes of LA (LAVmin, LAVmax, LAVpreA, LAEV), LA ejection fraction (LAEF), LA reservoir longitudinal and circumferential strains (LASr, LASr-c), LA conduit longitudinal and circumferential strains (LAScd, LAScd-c) and LA contraction longitudinal and circumferential strains (LASct, LASct-c). Logistic regression models were used to analyze the value of LA parameters in predicting LV remodeling in patients with CHD. ROC curve was used to evaluate LA parameters and left atrial volume index (LAVI) to predict the diagnostic efficiency of LV remodeling. Results:Compared with the Non-LV remodeling group, LAVmin, LAVmax, LAVpreA were significantly increased and LAEF, LASr, LAScd, LASct, LASr-c, LAScd-c, LASct-c were significantly decreased in the LV remodeling group ( P<0.05). Logistic regression model showed that LASct-c was an independent risk factor for LV remodeling in patients with CHD after adjustment( OR=2.018, 95% CI=1.214-3.355). ROC curve analysis showed that the area under the curve of LASct-c for predicting LV remodeling in CHD patients was 0.844, the sensitivity was 0.784, and the specificity was 0.761. Conclusions:4D Auto LAQ can effectively evaluate LA function in patients with CHD.LASct-c can be used as a reference index to predict LV remodeling in patients with CHD, which provides a new evaluation method in prognosis evaluation of CHD patients.

Objective:To develop a multi-scale fusion and attention mechanism based image automatic segmentation method of organs at risk (OAR) from head and neck carcinoma radiotherapy.Methods:We proposed a new OAR segmentation method for medical images of heads and necks based on the U-Net convolution neural network. Spatial and channel squeeze excitation (csSE) attention block were combined with the U-Net, aiming to enhance the feature expression ability. We also proposed a multi-scale block in the U-Net encoding stage to supplement characteristic information. Dice similarity coefficient (DSC) and 95% Hausdorff distance (HD) were used as evaluation criteria for deep learning performance.Results:The segmentation of 22 OAR in the head and neck was performed according to the medical image computing computer assisted intervention (MICCAI) StructSeg2019 dataset. The proposed method improved the average segmentation accuracy by 3%-6% compared with existing methods. The average DSC in the segmentation of 22 OAR in the head and neck was 78.90% and the average 95%HD was 6.23 mm.Conclusion:Automatic segmentation of OAR from the head and neck CT using multi-scale fusion and attention mechanism achieves high segmentation accuracy, which is promising for enhancing the accuracy and efficiency of radiotherapy in clinical practice.

Oral squamous cell carcinoma (OSCC) is a prevalent malignant tumor affecting the head and neck region (Leemans et al., 2018). It is often diagnosed at a later stage, leading to a poor prognosis (Muzaffar et al., 2021; Li et al., 2023). Despite advances in OSCC treatment, the overall 5-year survival rate of OSCC patients remains alarmingly low, falling below 50% (Jehn et al., 2019; Johnson et al., 2020). According to statistics, only 50% of patients with oral cancer can be treated with surgery. Once discovered, it is more frequently at an advanced stage. In addition, owing to the aggressively invasive and metastatic characteristics of OSCC, most patients die within one year of diagnosis. Hence, the pursuit of novel therapeutic drugs and treatments to improve the response of oral cancer to medication, along with a deeper understanding of their effects, remains crucial objectives in oral cancer research (Johnson et al., 2020; Bhat et al., 2021; Chen et al., 2023; Ruffin et al., 2023).

Objective:To investigate the preference for Front-of-Pack Labeling (FOP) and its association with the understanding of the Nutrition Facts Panel among Chinese residents.Methods:A multi-stage sampling strategy was adopted to select 3 002 people aged between 18 and 70 years old from the eastern region of China (Beijing, Jiangsu Province, Guangdong Province), the northeast region (Heilongjiang Province), the central region (Henan Province) and the western region (Sichuan Province) from July 2020 to March 2021. Socio-demographic characteristics of participants and their understanding of the Nutrition Facts Panel and preference for FOP were collected. The χ2 test was conducted to compare the preference for FOP in different groups of population, and multivariate logistic regression was used to analyze the association between the preference for FOP and the understanding of the Nutrition Facts Panel. Results:The mean age of 3 002 participants was (42.3±13.4) years, of which 1 914 (63.8%) were females and 69.3% could not understand the Nutrition Facts Panel. About 2 458 respondents (81.9%) suggested that FOP could be promoted. The top three nutrients that should be labeled were sugar (68.4%), salt (68.2%) and total fat (62.4%). The number of participants who believed that the Multiple Traffic Lights (MTL) could be easier to help consumers to quickly choose healthy food, attract attention and provide the most needed information was 1 064 (35.4%), 1 026 (34.2%) and 1 140 (38.0%), respectively. The multivariate logistic regression analysis showed that, compared with the Guideline Daily Amount (GDA) system, participants who could not understand the Nutrition Facts Panel preferred (1) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could quickly help you choose food more easily?"[ OR (95% CI): 2.21 (1.62-3.02), 1.64 (1.22-2.22), 1.79 (1.31-2.45), respectively]; (2) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could attract your attention the most?"[ OR (95% CI): 2.62 (1.92-3.59), 1.96 (1.45-2.66), 2.25 (1.66-3.04), respectively]; and (3) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could provide you with the most needed information?"[ OR (95% CI): 2.33 (1.70-3.21), 2.21 (1.66-2.95), 2.01 (1.50-2.71), respectively]. Conclusion:The residents from six provinces in China have a supportive attitude towards FOP. The interpretive FOP with color information, specific nutrient information and summary indicator can be launched. The nutrition information of sugar, salt and total fat could be prioritized to be labeled on the FOP.
