Cronobacter spp. has strong resistance to desiccation and high permeability in Enterobacteriaceae， and powdered infant formula (PIF) is one of the main contamination routes. In recent years， the contamination of Cronobacter spp. in PIF incidents occur from time to time， causing infant serious diseases or death. In this investigation， matrix-assisted laser desorption/ionization time of flight mass spectrometry was used to identify the phenotypes of 35 Cronobacter strains isolated from PIF and its processing environment. Subsequently， the isolates were evaluated for drying and osmotic pressure tolerance. The results showed that the deactivation rate of the strains ranged from 9.01% to 77.57%， and the highest osmotic pressure condition the strains could tolerate was 6% NaCl. In addition， there was a positive correlation between biofilm formation ability and desiccation resistance. Combined with transcriptomics， Cronobacter spp. can activate biofilm synthesis， produce more trehalose， accumulate betaine and electrolytes to stabilize intracellular structure under the two treatment conditions. 31 and 43 genes were found related to desiccation and permeability resistance， respectively. And some genes (cysM， thuF， ycjO， et al) were found to be associated with two tolerances for the first time.

Background:The prevalence of multimorbidity is increasing,with a notable shift towards younger age ***:Convenience sampling was employed to select 15,988 young and middle-aged adults in Chongqing as the study *** Apriori algorithm was used to identify the multimorbidity patterns within this population,while an unordered binary logistic regression model was applied to assess the association between sleep,diet and the risk of ***:The study population had an average age of 39.2±10.1 *** association rules revealed that the most prevalent binary chronic disease multimorbidity pattern was dyslipidaemia+hypertension(14.78%),while the most common ternary chronic disease multimorbidity pattern was diabetes+dyslipidaemia+hypertension(9.66%).The logistic regression analysis revealed that a lower rating of sleep quality was associated with an elevated risk of multimorbidity(odds ratio(OR)=1.17,95%confidence interval(CI):1.01,1.36).Individuals who adhere to a meat-based diet(OR=1.45,95%CI:1.25,1.68)and those with elevated salt intake(OR=1.22,95%CI:1.01,1.47)were also observed to have an increased risk of ***,a greater likelihood of multimorbidity was observed among those following a spicy diet(OR=1.3,95%CI:1.11,1.52)and consuming more oil(OR=1.16,95%CI:1.01,1.33).Conclusion:A poor sleep quality and a dietary preference for meat-based,salt,spicy and oils were found to be associated with an increased risk of multimorbidity progression among young and middle-aged *** is recommended that young and middle-aged adults should pay attention not only to sleep duration but also to sleep quality and improve dietary habits to reduce the likelihood of multimorbidity.

直播电商广告在推动产业快速发展的同时,也存在着诸多问题。为了对其进行规制,2023年出台的《互联网广告管理办法》明确了《广告法》对直播电商广告的适用性,然而直播电商广告违法现象仍层出不穷。直播电商规模庞大、违法广告获取证据固定证据困难、难以有针对性地展开监测使直播电商广告监管面临困境,亟需探寻法律规制之外的协同监管路径。在直播电商广告中,直播电商广告活动主体与消费者间存在信用关系,表现为消费者对直播电商产品的购买是以对直播电商广告的信任为前提、直播电商广告信用是直播电商广告活动主体与消费者信任程度的沉淀、直播电商广告信用是直播电商广告活动主体与消费者间的默认契约、直播电商广告信用具有市场价值。广告信用监管是维护直播电商广告活动主体与消费者间信用关系的必要路径。直播电商广告信用监管的本质是直播电商广告的制度伦理,其特征包括回应性、包容性和敏捷性。直播电商广告信用监管的实现需要进行两方面的机制设计,分别是基于广告信用监管目标进行制度设计伦理的机制设计和基于广告信用监管实施进行制度运行伦理的机制设计。
