Objective To investigate the relationship between serum miR-199a-5p and miR-378a-3p levels and the recurrence of infants with proliferative facial hemangioma relapsed after propranolol withdrawal in infants. Methods Ninety-three infants with proliferative facial hemangioma were selected, all of whom received propranolol treatment. The recurrence of the hemangioma after treatment was followed up, and the children were divided into a recurrence group (23 patients) and a nonrecurrence group (70 patients). Venous blood was collected before and after treatment, and the serum levels of miR-199a-5p and miR-378a-3p were detected by qRT-PCR, and the relationship between the serum levels of miR-199a-5p and miR-378a-3p and the recurrence of proliferative facial hemangioma relapsed after propranolol withdrawal in infants was analyzed. Results The serum expressions levels of miR-199a-5p and miR-378a-3p in non-relapsed group were increased after treatment compared with before treatment (P < 0.05), and there was no significant difference in the levels of miR-199a-5p and miR-378a-3p in the serum of the recurrence group after treatment compared with before treatment (P > 0.05). After treatment, the levels of miR-199a-5p and miR-378a-3p in the serum of the recurrence group were lower than those of the nonrecurrence group (P < 0.05). After treatment, the serum levels of miR-199a-5p and miR-378a-3p in patients with Ⅲ ~Ⅳ Norm grade hemangioma were higher than those in patients with Ⅰ~Ⅱ Norm grade hemangioma (P < 0.05). Logistic regression analysis showed that the low expression of miR-199a-5p, low expression of miR-378a-3p and tumor grade Ⅰ~Ⅱ after treatment were risk factors for the recurrence of proliferative facial hemangioma after propranolol withdrawal in infants (P < 0.05). Conclusion Low serum levels of miR-199a-5p and miR-378a-3p are associated with the recurrence of proliferative facial hemangioma after propranolol withdrawal in infants.

Background: Although the Healthy Eating Index (HEI) is widely recommended to reduce the risk of cardiovascular disease and all-cause death, there are significant differences in physiological and nutritional factors between the sexes. The potential impact of sex on adult dietary health is still poorly understood. The study was designed to assess whether the health benefits of diet differed by sex. Methods: In a prospective study of 39,567 U.S. adults (51.2% female, age 46.8 ± 17.6 years), we examined sex-specific, multivariable-adjusted associations of HEI with all-cause mortality and cardiovascular disease mortality. Restricted cubic splines (RCS), subgroup analysis, propensity score matching (PSM), random forest feature importance, and sensitivity analysis were also used. Results: During 328,403 person-years of follow-up, a total of 4754 all-cause deaths were recorded, including 1481 cardiovascular deaths. Compared to the lowest quartile of HEI, the all-cause mortality rate of females and males in the highest quartile array decreased by 34% (HR 0.66 [95% CI 0.55–0.8]) and 15% (HR 0.85 [95% CI 0.73–0.99]), respectively. The restricted cubic spline showed a linear inverse association between baseline HEI and all-cause mortality and CVD mortality, with similar sex-specific results. Similarly, component scores were sex-specific for mortality risk, with females benefiting more from diet. The benefits of dairy products, vegetables, and sodium scores on the risk of all-cause death were higher in males and females. However, the benefits of vegetable, sodium, and fatty acid scores on the risk of cardiovascular death were different. Conclusions: In the adult population of the U.S., there are more opportunities for females to reduce the risk of all-cause mortality and cardiovascular mortality from the same dose of healthy dietary intake than males. These findings could reduce the risk of death by motivating the population, especially females, to consume healthy dietary components, especially vegetables and dairy products.

This study aimed to assess the effects of Chinese Baijiu with different flavors as supplementary material on microbial communities and flavor formation during inoculated fermentation of Chinese Dongbei Suancai. The results showed that the addition of Fen flavor Baijiu significantly increased the relative abundance of Candida, Luzhou flavor Baijiu increased the relative abundance of Pedobacter and Hannaella, while Maotai flavor Baijiu increased the Chryseobacterium and Kazachstania. A total of 226 volatile metabolites were detected in Suancai fermented when adding different flavors of Baijiu. Furthermore, the significantly upregulated metabolites (p < 0.01) of Suancai after adding Baijiu increased by 328.57%, whereas the significantly downregulated metabolites decreased by 74.60%. Simultaneously, the addition of Baijiu promoted the synthesis and decomposition of amino acids and short-chain fatty acids in the early and middle stages of fermentation. Further, Maotai flavor Baijiu improved the diversification of metabolic pathways in the late stage of Suancai fermentation. The E-nose response showed that sulfur-organic, broad-alcohol, sulfur-chlor was the principal differential flavor in Suancai caused by adding Baijiu with different flavors. Simultaneously, Fen flavor Baijiu and Luzhou flavor Baijiu accelerated the formation of the Suancai flavor. These results indicated that Baijiu with different flavors had significant effects on the flavor formation of inoculated fermented Suancai. [ABSTRACT FROM AUTHOR]

Harsh environments such as alternating wet and dry conditions and cyclic loading cause erosion in steel bars, leading to severe damage to structures. Steel bars are also prone to bending under long-term fatigue loads. This paper establishes the bending performance test of corroded reinforced concrete (RC) beam under fatigue load based on the mathematical–statistical algorithm. It investigates the influence of heavy load on the fatigue performance of damaged RC beams, the influence of corrosive environment on the fatigue performance of RC beams, the degree of corrosion of steel bars in concrete beams under fatigue loading, and the distribution of chloride ions. The study results found that the stress ratio has a significant effect on the maximum crack width of the specimen beam. The greater is the stress ratio, the longer the fatigue life. This directly affects the performance of the specimen beam under fatigue loading. For this reason, we should pay special attention to the impact of corrosion on the fatigue performance of a structure during the design of steel bars.
