肢体缺血预处理对肝硬变兔肝脏缺血再灌注损伤的实验研究

目的:探索肢体缺血预处理对肝脏缺血再灌注损伤的影响.方法:32只新西兰兔用四氯化碳颈背部皮下注射法建立肝硬变模型.将成功建模的28只肝硬变兔分为假手术组(S组)、缺血再灌注组(IR组)、肝脏缺血预处理组(IPC组)、肢体缺血预处理组(LIPC组)各7只.实验前12h禁食,自由饮水.检测模型试验前后肝脏生化酶(ALT、AST)指标及肝脏组织中ATP含量水平.结果:LIPC组ALT、AST指标与S组、IR组比较差异均有显著统计学意义(P＜0.01),与IPC组比较无统计学意义(P＞0.05);LIPC组ATP指标水平与S组、IR组比较差异均有显著统计学意义(P＜0.01),与IPC组比较无统计学意义(P＞0.05).结论:肢体缺血预处理对肝脏缺血再灌注损伤具有保护作用.     

碘难治性分化型甲状腺癌的最新研究进展

近年来,作为最常见的恶性肿瘤之一,甲状腺癌的发病率曲线明显上升。分化型甲状腺癌经过手术、¹³¹I放疗及促甲状腺激素抑制等治疗后,大多数患者总体预后良好。但仍有少部分患者对放射性碘治疗不敏感且有1个或多个癌基因的突变,则成为病情进展快、死亡率高的碘难治性分化型甲状腺癌。应用上述的传统治疗手段难以取得满意疗效,本文综述了碘难治性分化型甲状腺癌的诊断及治疗进展,为尽早识别及早期进行靶向治疗等争取必要的时间。

Investigating the Impact of the New York State Flavor Ban on e-Cigarette–Related Discussions on Twitter: Observational Study

BackgroundOn May 18, 2020, the New York State Department of Health implemented a statewide flavor ban to prohibit the sales of all flavored vapor products, except for tobacco or any other authorized flavor.ObjectiveThis study aims to investigate the discussion changes in e-cigarette–related tweets over time with the implementation of the New York State flavor ban.MethodsThrough the Twitter streaming application programming interface, 59,883 e-cigarette–related tweets were collected within the New York State from February 6, 2020, to May 17, 2020 (period 1, before the implementation of the flavor ban), May 18, 2020-June 30, 2020 (period 2, between the implementation of the flavor ban and the online sales ban), July 1, 2020-September 15, 2020 (period 3, the short term after the online sales ban), and September 16, 2020-November 30, 2020 (period 4, the long term after the online sales ban). Sentiment analysis and topic modeling were conducted to investigate the changes in public attitudes and discussions in e-cigarette–related tweets. The popularity of different e-cigarette flavor categories was compared before and after the implementation of the New York State flavor ban.ResultsOur results showed that the proportion of e-cigarette–related tweets with negative sentiment significantly decreased (4305/13,246, 32.5% vs 3855/14,455, 26.67%, P<.001), and tweets with positive sentiment significantly increased (5246/13,246, 39.6% vs 7038/14,455, 48.69%, P<.001) in period 4 compared to period 3. “Teens and nicotine products” was the most frequently discussed e-cigarette–related topic in the negative tweets. In contrast, “nicotine products and quitting” was more prevalent in positive tweets. The proportion of tweets mentioning mint and menthol flavors significantly increased right after the flavor ban and decreased to lower levels over time. The proportions of fruit and sweet flavors were most frequently mentioned in period 1, decreased in period 2, and dominated again in period 4.ConclusionsThe proportion of e-cigarette–related tweets with different attitudes and frequently discussed flavor categories changed over time after the implementation of the New York State ban of flavored vaping products. This change indicated a potential impact of the flavor ban on public discussions of flavored e-cigarettes.
