BACKGROUND: The benefits of ideal cardiovascular-health metrics (ICVHMs) in patients with renal insufficiency remain unclear. This study aimed to investigate the associations between ICVHM and prognosis in a renal insufficiency population. METHODS: The trial enrolled 29,682 participants from the US National Health and Nutrition Examination Survey (NHANES), 2007-2018, with mortality follow-up through December 31, 2019. Participants were divided into three groups based on estimated glomerular filtration rates. Cardiovascular health was assessed using new "Life's Essential 8" metrics. Cox regression analyses based on NHANES data were used to determine the associations between ICVHMs and cardiovascular mortality in patients with renal insufficiency. RESULTS: During a mean follow-up of 6.58 years, ideal cardiovascular health (hazard ratio [HR] = 0.42; 95% confidence interval [CI]; 0.25-0.70) and ideal health behavior (HR = 0.53; 95% CI; 0.39-0.73) reduced cardiovascular mortality in participants with renal insufficiency. For each one ICVHM increment, a 25% reduction in cardiovascular mortality was recorded (95% CI; 0.69-0.82). When compared with participants with normal renal function, for those with mild renal insufficiency, the HR for cardiovascular mortality gradually decreased from 1.47 (95% CI; 0.85-2.52) in those who had ≤1 ICVHMs to 0.30 (95% CI; 0.12-0.77) in participants who had >6 ICVHMs. CONCLUSIONS From an ICVHM perspective, enhanced cardiovascular benefits were observed in individuals with renal insufficiency, coupled with a reduced risk of all-cause mortality. Furthermore, when compared with individuals with normal renal function, increased ICVHMs can mitigate adverse risks associated with renal impairment.

Objective:To systematically evaluate the effectiveness and feasibility of aerobic exercise intervention in schizophrenia patients.Methods:Randomized controlled trials on exercise interventions for patients with schizophrenia were searched in eight databases from built up to March 2023, including China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals (VIP), WanFang Data, China Biomedical Literature Database, PubMed, Cochrane Library, EMBASE and Web of Science. The positive and negative symptom scale (PANSS) and its sub-scales were used as primary outcome indicators, and the negative symptom scale (SANS) and body mass index (BMI) were used as secondary indicators, and Meta-analysis was performed using R 4.1.0 and Stata 14.0.Results:Forty-seven studies including 3 139 patients with schizophrenia were included. Results of a network Meta-analysis based on 24 studies showed that aerobic exercise may be the most effective measure for reducing total PANSS scores in patients with schizophrenia. Compared to conventional treatment, combining aerobic exercise intervention improved patients' PANSS total score (MD= -5.09, 95% CI: -5.90~-4.28), SANS (MD= -12.17, 95% CI: -14.25~-10.10), and BMI (MD=-1.59, 95% CI: -1.93~-1.25). Meanwhile, subgroup analysis showed that 2 months of intervention was more appropriate (MD=-6.12, 95% CI: -7.22~-5.02) and the weekly total exercise time for 140-260 min was more appropriate (MD=-8.59, 95% CI: -12.93~-4.25) in terms of total PANSS score. The adherence rates between the trial and control groups showed no significant difference between the aerobic exercise intervention combined with conventional treatment and conventional treatment alone( P>0.05). Conclusion:Aerobic exercise intervention is an effective measure to relieve the symptoms of schizophrenia patients and has good compliance among inpatients.

Objective:Lung cancer is characterized by its high incidence and case fatality rate.Factors related to population composition and cancer prevention programme policy have an effect on the incidence and diagnosis of lung cancer.This study aims to provide scientific support for early diagnosis and treatment of lung cancer by investigating the clinic information,pathological,and imaging characteristics of surgical patients with lung cancer. Methods:The data of 2 058 patients,who underwent surgery for lung cancer in the Department of Thoracic Surgery of Xiangya Hospital of Central South University from 2016 to 2019,were retrospectively collected to analyze changes in clinic information,pathological,and imaging characteristics. Results:From 2016 to 2019,the number of patients per year was 280,376,524,and 878,respectively.Adenocarcinoma(68.1%)was the most common pathological type of surgical patients with lung cancer.From 2016 to 2019,the proportion of adenocarcinoma was increased from 55.5%to 74.1%.The proportion lung cancer patients in stage IA was increased from 38.9%to 62.3%,and the proportion of patients who underwent sublobar resection was increased from 1.8%to 8.6%.The proportion of lymph node sampling was increased in 2019.Compared with the rate in 2016,the detection rate of nodules with diameter≤1 cm detected by CT before surgery in 2019 was significantly improved(2.0%vs 18.2%),and the detection rate of nodules with diameter>3 cm was decreased(34.7%vs 18.3%).From 2016 to 2019,the proportion of lesions with pure ground-glass density and partial solid density detected by CT was increased from 2.0%and 16.6%to 20.0%and 37.3%,respectively.The proportion of solid density was decreased from 81.4%to 42.7%. Conclusion:The number of lung cancer surgery patients is rapidly increasing year by year,the proportion of CT-detected purely ground-glass density and partially solid density lesions are increasing,the proportion of patients with adenocarcinoma is rising,the proportion of early-stage lung cancer is increasing,smaller lung cancers are detected in earlier clinical stage leading to a more minimally invasive approach to the surgical methods.

Objective:Radiotherapy is the primary treatment for nasopharyngeal carcinoma,but it frequently leads to radiotherapy-induced temporal lobe injury(RTLI).Magnetic resonance imaging(MRI)is the main diagnostic method for RTLI after radiotherapy for nasopharyngeal carcinoma,but it is prone to missed diagnoses.This study aims to investigate the causes of missed diagnoses of RTLI in nasopharyngeal carcinoma patients undergoing MRI after radiotherapy. Methods:Clinical and MRI data from nasopharyngeal carcinoma patients diagnosed and treated with radiotherapy at Xiangya Hospital of Central South University,from January 2010 to April 2021,were collected.Two radiologists reviewed all head and neck MRIs(including nasopharyngeal and brain MRIs)before and after radiotherapy of identify cases of late delayed response-type RTLI for the first time.If the original diagnosis of the initial RTLI in nasopharyngeal carcinoma patients did not report temporal lobe lesions,it was defined as a missed diagnosis.The first diagnosis of RTLI cases was divided into a missed diagnosis group and a non-missed diagnosis group.Clinical and imaging data were compared between the 2 groups,and multivariate logistic regression analysis was used to identify independent risk factors for MRI missed diagnoses of initial RTLI. Results:A total of 187 nasopharyngeal carcinoma with post-radiotherapy RTLI were included.The original diagnostic reports missed 120 cases and accurately diagnosed 67 cases,with an initial RTLI diagnosis accuracy rate of 35.8%and a missed diagnosis rate of 64.2%.There were statistically significant differences between the missed diagnosis group and the non-missed diagnosis group in terms of lesion size,location,presence of contralateral temporal lobe lesions,white matter high signal,cystic degeneration,hemorrhage,fluid attenuated inversion recovery(FLAIR),and examination site(all P<0.05).Multivariate logistic regression analysis showed that lesions≤25 mm,non-enhancing lesions,lesions without cystic degeneration or hemorrhage,lesions located only in the medial temporal lobe,and MRI examination only of the nasopharynx were independent risk factors for missed MRI diagnosis of initial RTLI(all P<0.05). Conclusion:The missed diagnosis of initial RTLI on MRI is mainly related to lesion size and location,imaging characteristics,and MRI examination site.

Objective To investigate the safety and feasibility of peripheral vascular intervention via the ipsilateral transulnar access(TUA)due to failure of transradial access(TRA)puncture.Methods The clinical data of 2546 peripheral vascular interventions via TRA,which were performed at authors'hospital between January 2019 and December 2021,were retrospectively analyzed.Among the 2546 interventions,TRA puncture failed in 37 procedures,and in 27 of these patients the ipsilateral TUA puncture had to be adopted.The puncture success rate,surgical success rate and puncture approach-related complications of TUA of the 27 patients receiving ipsilateral TUA puncture were analyzed.Results The success rate of ipsilateral TUA puncture after TRA puncture failed was 96.3％(26/27),and in one patient transfemoral access(TFA)puncture had to be substituted because of the ulnar artery spasm.The total success rate of interventional procedures was 96.3％(26/27).No serious complications occurred,and the incidence of minor complications was 19.2％(5/26).Conclusion Preliminary results indicate that for the experienced TRA operators,using ipsilateral TUA puncture due to failure of TRA puncture is a safe and feasible strategy choice.

OBJECTIVES: Digital subtraction angiography (DSA) is the current gold standard for diagnosing spinal dural arteriovenous fistulas (SDAVF). However, DSA is invasive and associated with risks such as ionizing radiation and iodine contrast allergy. Contrast-enhanced magnetic resonance angiography (CE-MRA) with high temporal/high spatial resolution allows dynamic multiphase contrast-enhanced imaging with excellent detail. This study aims to evaluate the diagnostic value of spinal CE-MRA with high temporal/high spatial resolution for SDAVF. METHODS: Clinical data were retrospectively collected from patients who underwent both conventional spinal MRI and high temporal/high spatial resolution CE-MRA at Xiangya Hospital between January 1, 2021, and January 1, 2024, and who subsequently underwent DSA or surgery within 90 days. Two experienced radiologists independently reviewed all conventional MRI and CE-MRA images. The sensitivity and specificity of conventional MRI and CE-MRA for diagnosing SDAVF were calculated against the gold standard DSA findings. Kappa statistics were used to evaluate the consistency of MRI and CE-MRA compared to DSA. The diagnostic value was further assessed by calculating the area under curve (AUC) of the receiver operating characteristic (ROC). RESULTS: A total of 60 patients were included, of whom 47 were diagnosed with SDAVF and 13 were not. Conventional MRI had 3 false negatives and 1 false positive; CE-MRA had 2 false positives and 0 false negative. The sensitivity and specificity of conventional MRI were 93.62% and 92.31%, respectively. CE-MRA demonstrated 100% sensitivity and 84.62% specificity. The main cause of false positives was the misidentification of posterior spinal arteries as feeding arteries. CE-MRA clearly displayed most feeding arteries, and the accuracy of fistula localization was 74.47% (35/47). Kappa values for conventional MRI and CE-MRA were 0.814 and 0.896, respectively (both P<0.001), indicating good agreement, with CE-MRA outperforming conventional MRI. The AUCs for diagnosing SDAVF were 0.930 for conventional MRI and 0.923 for CE-MRA (both P<0.05). CONCLUSIONS Spinal CE-MRA with high temporal/high spatial resolution is a reliable, non-invasive imaging technique with high sensitivity for diagnosing SDAVF. It can clearly visualize feeding arteries and provides valuable preoperative diagnostic and localization information to support DSA or surgical planning.

Objective:Intravascular large B-cell lymphomas are a rare group of extranodal non-Hodgkin's lymphomas with no apparent specificity of symptoms and often a poor prognosis.This study aims to investigate the clinical features and imaging manifestations of intravascular large B-cell lymphoma,to improve the awareness of clinicians and imaging physicians and to reduce the underdiagnosis and misdiagnosis of this disease. Methods:Five patients with pathologically confirmed intravascular large B-cell lymphoma diagnosed between December 2011 and February 2022 at Xiangya Hospital of Central South University were retrospectively analyzed for clinical features and imaging manifestations. Results:The age range for the 5 patients in this paper was 44-72 years at an average of(55.4±11.2)years,2 were male and 3 were female.There were 4 patients with fever,3 patients with cough,3 patients with fatigue,and 2 patients with neurological symptoms.The primary sites of lesions were bilateral adrenal glands(2 cases),liver(1 case),central nervous system(1 case),lung(1 case).Imaging of the corresponding site was performed in 5 cases.When the primary site is the adrenal gland,it appears as bilateral adrenal masses or bilateral adrenal thickening with clear contours.When the primary site is the liver,it appears as a hypodense lesion in the right lobe of the liver with"vascular floating sign".When the primary site is the central nervous system,it appears as multiple tumor-like lesions in the frontal-parietal-occipital lobe,right temporal lobe and bilateral cerebellar hemispheres with multiple hemorrhages within the lesions.When the primary site is the lung,it appears as multiple ground glass shadows and solid changes in both lungs with localized lobular septal thickening.The final pathological diagnosis was intravascular large B-cell lymphoma in all 5 patients,one of whom had a good prognosis after chemotherapy,2 of whom died within 3 days of discharge,and two of whom were lost to follow-up. Conclusion:Intravascular large B-cell lymphoma can involve multiple tissues and organs,and its prognosis is often poor,and its imaging manifestations possess certain specificity.When this disease is highly suspected,a biopsy of the corresponding organ should be performed as soon as possible to clarify the diagnosis.

Objective:To explore the role of active screening in the diagnosis and treatment of early lung cancer, and give health management recommendations.Methods:A retrospective study was conducted to collect lung cancer patients who had complete population sociology, clinical information, pathology and imaging characteristics in the Thoracic Surgery in Xiangya Hospital of Central South University from 2016 to 2019. According to different diagnostic modes, they were divided into an active screening group (1082 cases) and a passive case finding group (974 cases), to analyze their differences in demographic sociological, clinical information, pathology and imaging characteristics, and to discuss the key points of population management in the active screening group.Results:From 2016 to 2019, the proportion of lung cancer patients in the active screening group increased from 36.1% to 54.2%, and the proportion of patients found to have lung cancer by CT examination in the active screening group increased from 82.2% to 96.8%. Compared with the passive case finding group, the active screening group had a higher proportion of women, non-smokers, patients with precursor glandular lesions and adenocarcinoma, patients in stage 0 and stage I, patients with lesion diameter (d)≤1 cm and 1

【Objective】 Dyslipidemia has shown to be associated with cardiovascular, metabolic and renal diseases. This study aimed to investigate the association between residual cholesterol and the risk of subclinical renal damage (SRD). 【Methods】 A total of 2 342 participants were recruited from the previously established Hanzhong Adolescent Hypertension Study cohort. According to estimated glomerular filtration rate(eGFR) and urinary albumin-to-creatine ratio(uACR), the subjects were divided into SRD group and non-SRD group. The associations of residual cholesterol with eGFR, uACR, and the risk of SRD were analyzed by multiple linear and Logistic regression analyses. 【Results】 Residual cholesterol was positively correlated with uACR(r=0.081, P<0.001) but negatively correlated with eGFR (r=-0.091, P<0.001). Multiple linear regression analysis revealed that residual cholesterol was an influencing factor of uACR (β=0.075, P<0.001) and eGFR (β=-0.027, P<0.001) after adjustment for gender, age, smoke, alcohol, exercise, BMI, hypertension, diabetes and serum uric acid. In addition, Logistic regression analysis revealed that residual cholesterol was significantly associated with the risk of SRD independently of potential confounders [OR(95% CI)=1.387 (1.113-1.728), P<0.001]. Further subgroup analysis showed that residual cholesterol was significantly associated with the risk of SRD in women but not in men. 【Conclusion】 Residual cholesterol is a contributing factor in the risk of subclinical renal damage with gender-specific association.

【Objective】 Corin, a transmembrane serine protease that can cleave atrial natriuretic peptide precursor (pro-ANP) into atrial natriuretic peptide with smaller bioactive molecules, participates in the pathophysiological process of hypertension and cardiac hypertrophy. The purpose of this study was to explore the relationship of Corin gene variation with blood pressure responses to sodium and potassium dietary interventions. 【Methods】 In 2004, we recruited 514 participants from 124 families in 7 villages of Baoji, Shaanxi Province, China. All the subjects received a 3-day normal diet, a 7-day low-salt diet, a 7-day high-salt diet, and finally a 7-day high-salt and potassium supplementation. Fifteen single nucleotide polymorphisms (SNPs) of Corin gene were selected for final analysis. 【Results】 SNPs rs12509275 were significantly associated with diastolic blood pressure (DBP) response to low-salt diet, while rs3749584 was associated with pulse pressure (PP) response to low-salt diet.SNP rs3749584 and rs10517195 were significantly associated with PP response to high-salt diet. In addition,rs17654278 were significantly associated with systolic blood pressure (SBP) response to high-salt and potassium supplementation, rs2271037 was significantly correlated with DBP responses to high-salt and potassium supplementation, and rs4695253, rs12509275, rs2351783, rs36090894 were significantly associated with PP response to high-salt and potassium supplementation. 【Conclusion】 Corin gene polymorphisms were associated with blood pressure response to sodium and potassium, suggesting that Corin gene may be involved in pathophysiological process of salt sensitivity and potassium sensitivity.
