为研究不同温度波动对冻藏南美白对虾品质影响规律,对-18℃冷柜设定不同的温度波动(±0.5、±2、±4、±6、±8℃)来冻藏南美白对虾,测量其挥发性盐基氮(total volatile basic nitrogen,TVB-N)、硫代巴比妥酸反应物(thiobarbituric acid reactive substance,TBARS)、L^(*)值、硬度、弹性、咀嚼性等指标在120 d内的变化,并与-40℃冻藏的南美白对虾品质对比。结果表明,南美白对虾TVB-N值、TBARS值和L^(*)值随冻藏时间的延长不断增加,硬度、弹性、咀嚼性等质构指标随冻藏时间的延长显著降低;在(-18±0.5)℃工况下,各物化指标更接近-40℃冻藏南美白对虾的品质,且温度波动幅度越大,各物化指标劣变速度越快,实用贮藏期显著降低;其中,当南美白对虾以全虾状态在(-18±8)℃的冷柜中冻藏至第108天时,TVB-N值超过国家标准规定的初步腐败界限30 mg/100 g,已经不可食用。由此可知在相同冻藏温度的情况下,减小温度波动幅度能有效抑制南美白对虾冻藏过程中的品质劣变,较好地保持其品质。

Background: The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with ***: In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled. Cases were patients with PE with elevated hs-cTnI. Controls were patients with PE with normal hs-cTnI. Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI ***: The percentage of CAS was higher in the case group compared to the control group (44.3% [39/88]vs. 30.1% [49/163];P = 0.024). In multivariable conditional logistic regression model 1, CAS (adjusted odds ratio [OR], 2.680; 95% confidence interval [CI], 1.243–5.779), heart rate >75 beats/min (OR, 2.306; 95% CI, 1.056–5.036) and N-terminal pro-B type natriuretic peptide (NT-proBNP) >420 pg/mL (OR, 12.169; 95% CI, 4.792–30.900) were independently associated with elevated hs-cTnI. In model 2, right CAS (OR, 3.615; 95% CI, 1.467–8.909) and NT-proBNP >420 pg/mL (OR, 13.890; 95% CI, 5.288–36.484) were independently associated with elevated ***: CAS was independently associated with myocardial injury in patients with PE. Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.

中国经济正在进行一系列结构性调整,新兴技术发展、人口老龄化与人口流动呈现出新的趋势。文章基于2000~2015年人口普查和小普查微观数据,研究了新兴技术和人口老龄化对劳动力跨省流动规模的影响。研究发现,新兴技术和人口老龄化是驱动中国劳动力跨省流动的重要因素。新兴技术更倾向于吸引年轻、高技能劳动力,同时通过互补作用吸纳更多低技能劳动力。人口老龄化使城市更依赖本地富有经验的中年劳动力和中低技能劳动力,但同时也通过产业转型升级增加对高技能劳动力的需求。此外,人口老龄化可以强化新兴技术对劳动力跨省流动的拉力作用。文章研究结论为优化劳动力资源配置、应对人口老龄化挑战提供了理论与实践参考,也为理解新兴技术发展和人口老龄化对中国劳动力空间配置的影响提供了实证依据。
