BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

ObjectiveTo investigate the value of the serum levels of Clusterin and sphingosine 1-phosphate （S1P） in assessing the prognosis of sepsis patients with acute liver injury. MethodsA total of 127 sepsis patients with acute liver injury who were admitted to Lianyungang Hospital， Xuzhou Medical University， from March 2019 to May 2022 were enrolled， and according to their prognosis after 28 days of treatment， they were divided into death group with 35 patients and survival group with 92 patients. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. A pearson correlation analysis was used to investigate the correlation. The prognostic value of serum Clusterin and S1P was analyzed by receiver operating characteristic curve. ResultsThere were significant differences between the two groups in the degree of liver injury， Acute Physiology and Chronic Health Evaluation Ⅱ （APACHEⅡ） score， Sequential Organ Failure Assessment （SOFA） score， the presence or absence of acute kidney injury， prothrombin time （PT）， international normalized ratio （INR）， Child-Pugh class， and C-reactive protein （all P<0.05）. The death group had significantly lower serum levels of Clusterin and S1P than the survival group （t=11.094 and 10.390， both P<0.05）. The patients with severe liver injury had significantly lower serum levels of Clusterin and S1P than those with mild or moderate liver injury （t=9.825 and 11.418， both P<0.05）. The multivariate regression analysis showed that the degree of liver injury （odds ratio ［OR］=1.260， 95% confidence interval ［CI］： 1.081 — 1.468， P<0.05）， APACHEII score （OR=1.031， 95%CI： 1.019 — 1.044， P<0.05）， SOFA score （OR=1.066， 95%CI： 1.039 — 1.094， P<0.05）， Clusterin （OR=0.899， 95%CI： 0.859 — 0.940， P<0.05）， and S1P （OR=0.824， 95%CI： 0.749 — 0.908， P<0.05） were independent risk factors for the prognosis of patients with sepsis. The ROC curve analysis showed that serum Clusterin and S1P used alone or in combination had an area under the ROC curve of 0.864， 0.861， and 0.949， respectively. Serum Clusterin and S1P were significantly negatively correlated with alanine aminotransferase， total bilirubin， PT， and INR in sepsis patients with acute liver injury （all P<0.05）. ConclusionThe sepsis patients with acute liver injury who died had significant reductions in serum Clusterin and S1P compared with those who survived， and the levels of Clusterin and S1P are closely associated with the degree of liver injury. The combination of Clusterin and S1P has a good value in predicting the prognosis of sepsis patients with acute liver injury and is expected to become a potential marker for predicting the prognosis of sepsis patients with acute liver injury.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective:To determine the current situation of food safety risk monitoring ability of centers for disease control and prevention （CDCs） in a province， and provide reference for strengthening the construction of food safety monitoring ability in the future. Methods:A self-administered questionnaire survey was conducted among 14 CDCs who are responsible for food safety risk monitoring in the province in 2018. Results:The ratio of food inspection staff with senior， middle， and primary professional titles was 1∶1∶1. The educational background of food inspection staff at the provincial and municipal levels was mainly bachelor degree or above， while that of county level directly under the administration of the province was mainly college degree. The age composition of the staff at the provincial level tended to be elder； however， there were more staff with less working experience at the county level. The qualification proportion of laboratory area was 50%. The distribution proportion of food inspection equipment in the CDC at all levels was 83.3%， 79.5% and 36.3%， respectively. In total， 14 CDCs completed the monitoring task as required. They were all accredited with laboratory qualifications； however， one CDC did not conduct re-evaluation after the certification of food inspection qualification expired. Each CDC ensured the accuracy and reliability of monitoring data through the supervision in food testing. Conclusion:The food safety risk monitoring ability of the CDCs in the province is continuously improved， which can meet the needs of routine monitoring. However， the composition of professional titles of food inspection staff is not very reasonable. There is still a gap between the equipment configuration and the national requirements. The ability of food inspection needs to be improved， in which quality management and laboratory qualification should be further strengthened.
