Objective:To investigate the association between air pollutant exposure levels and the risk of atrial fibrillation and to evaluate the mediating role of serum uric acid levels in the association between air pollutant levels and atrial fibrillation risks.Methods:This study was a case-control study, and the data of the atrial fibrillation group was derived from atrial fibrillation patients diagnosed at the Zhongda Hospital, Affiliated to Southeast University, from January 2014 to April 2021, and data of control group was derived from those without atrial fibrillation at the screening in Qixia District, Nanjing City, in March to April 2019. A 1∶1 propensity score matching was performed with the matched variables of age and sex. Air pollutant exposure data were collected from 9 air quality monitoring stations in Nanjing from January 2014 to April 2021, including NO 2, CO, PM 2.5 and PM 10. Exposure to air pollutants was converted to respiratory exposure levels according to an approximate formula. Multivariate logistic regression models were used to analyze the association between air pollutants and the risk of atrial fibrillation. Mediation analysis was used to investigate the mediating role and magnitude of serum uric acid in the association pathway between the four air pollutants (PM 2.5, PM 10, NO 2, and CO) and atrial fibrillation. Results:The atrial fibrillation group was aged (68.7±11.3) years, with 544 (51.8%) males; the control group was aged (68.5±8.9) years, with 543 (51.7%) males. Multivariate logistic regression models suggested that individual exposure levels of all four air pollutants were associated with the increased risks of atrial fibrillation. Every 1 μg·kg -1·d -1 increased in NO 2 was associated 12.1% increased risk of atrial fibrillation among the individuals ( OR=1.121, 95% CI:1.098-1.144); For every 1 μg·kg -1·d -1 increased in CO, the individual risk of atrial fibrillation increased by 0.7% ( OR=1.007, 95% CI: 1.006-1.008). For each 1 μg·kg -1·d -1 increase in PM 2.5 exposure level, the individual risk of atrial fibrillation increased by 14.2% ( OR=1.142, 95% CI: 1.120-1.164). For each 1 μg·kg -1·d -1 increase in PM 10 exposure level, the individual risk of atrial fibrillation increased by 3.7% ( OR=1.037, 95% CI: 1.028-1.046). The results of the mediation analysis suggested that serum uric acid levels mediated 5.6% ( P=0.032) causal effects of PM 2.5 on atrial fibrillation risks and 7.5% ( P=0.010) mediated by CO. Conclusion:Air pollutant exposure was a risk factor for the development of atrial fibrillation and uric acid mediated the increased risk of atrial fibrillation by PM 2.5 and CO.

Objective To explore the effect of moxibustion combined with low molecular weight heparin in patients with hypercoagulable tumor.Methods Convenience sampling was used to select 128 patients with high coagulation status of tumors hospitalized in the oncology department of a tertiary A Traditional Chinese Medicine hospital from February 2022 to June 2023 as the research subjects.The patients were randomly divided into an experimental group and a control group by a random number table method,with 64 cases in each group.The control group was treated with conventional prevention and treatment measures combined with low molecular weight heparin,while the experimental group was treated with moxibustion on the basis of measures in the control group.The intervention period was 2 courses,with each course lasting 5 days.The thromboelastography and coagulation indicators of the 2 groups of patients were compared on the 1st,6th,and 11th day after enrollment.Results A total of 124 cases completed the experiment,with 2 cases lost in the experimental group and 2 cases lost in the control group.The results of repeated measures analysis of variance showed that there was a time effect on the coagulation reaction time between the 2 groups(F=8.797,P=0.004);simple effects analysis showed that on the 11th day of intervention,the coagulation reaction time in the experimental group was higher than 1st day of intervention,and the difference was statistically significant(t=-2.225,P=0.028).Conclusion Moxibustion combined with low molecular weight heparin can prolong coagulation initiation time,reduce coagulation factor activity,improve hypercoagulability in tumor patients,and thus prevent deep vein thrombosis in tumor patients.

Primary ciliary dyskinesia (PCD) is a highly heterogeneous recessive inherited disorder. FAP54, the homolog of CFAP54 in Chlamydomonas reinhardtii, was previously demonstrated as the C1d projection of the central microtubule apparatus of flagella. A Cfap54 knockout mouse model was then reported to have PCD-relevant phenotypes. Through whole-exome sequencing, compound heterozygous variants c.2649_2657delinC (p. E883Dfs*47) and c.7312_7313insCGCAGGCTGAATTCTTGG (p. T2438delinsTQAEFLA) in a new suspected PCD-relevant gene, CFAP54, were identified in an individual with PCD. Two missense variants, c.4112A>C (p. E1371A) and c.6559C>T (p. P2187S), in CFAP54 were detected in another unrelated patient. In this study, a minigene assay was conducted on the frameshift mutation showing a reduction in mRNA expression. In addition, a CFAP54 in-frame variant knock-in mouse model was established, which recapitulated the typical symptoms of PCD, including hydrocephalus, infertility, and mucus accumulation in nasal sinuses. Correspondingly, two missense variants were deleterious, with a dramatic reduction in mRNA abundance from bronchial tissue and sperm. The identification of PCD-causing variants of CFAP54 in two unrelated patients with PCD for the first time provides strong supportive evidence that CFAP54 is a new PCD-causing gene. This study further helps expand the disease-associated gene spectrum and improve genetic testing for PCD diagnosis in the future.
