N6-methyladenosine(m6A)is the most common mRNA modification in eukaryotes,and fat mass and obesity-related protein(FTO),are its demethylases,which efficiently remove the modification of m6A mRNA,and is strongly associated with obesity.Atherosclerosis is a chronic inflammatory lesion of the blood vessel wall driven by lipids.It was found that FTO-mediated m6A may influence the process of atherosclerosis through lipid metabolism,oxidative stress,mitochondrial dysfunction,and macrophage foaminess.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.

Objective To explore the feasibility,necessity and the skill of total mesoesophageal excision (TME ) during thoracoscopy combined with laparoscopy in radical resection of esophageal carcinoma.Methods 69 patients with esophageal carcinoma were divided into the TME group(40 cases)and the thoracotomy with triple incisions group(29 cases)according to the admission sequence.The operation time,intraoperative blood loss,total lymph nodes removed,postoperative complication rate and disease -free survival were compared between the two groups.Results The operation time of TME group was (182.85 ±26.73)min,which was significantly shorter than (295.71 ±19.50)min of the thoracotomy group (t=-19.301,P<0.001).The intraoperative blood loss in TME group was (86.43 ±59.34)mL,which was significantly less than (163.47 ±58.82)mL in the thoracotomy group (t=-5.342,P<0.001 ).No significant differences were detected between the two groups in total lymph nodes removed and incidence rate of postoperative complication (all P>0.05 ).The disease-free survival period in TME group was (14.78 ±2.14)months,which in the thoracotomy group was (13.10 ±4.09)months,the difference was significant (t=2.200,P<0.05).Conclusion TME is safe and feasible during thoracoscopy combined with laparos-copy in radical resection of esophageal carcinoma.TME is better in improving the regional control in esophageal carci-noma.
