目的：研究10g/L胼酞嗪滴眼液对剂量为35mg/kg的NaIO3诱导的大鼠RPE变性的对抗作用。方法：经舌下静脉予Brown Norway大鼠分别注射不同剂量的NaIO3及生理盐水,注射3,7,14及28d后测量ERG的a、b、c、FO及LP波,同时进行眼底彩照和眼底荧光血管造影检查。用光学显微镜或自体荧光平片对部分大鼠进行组织学研究。在体外培养RPE-19细胞,观察不同浓度的NaIO3对细胞的影响并测其细胞增殖率。经舌下静脉予BrownNorway大鼠注射剂量为35mg/kg的NaIO3。NaIO3组大鼠注射NaIO3后用生理盐水点眼,10g/L胼酞嗪＋NaIO3组大鼠注射NaIO3后用10g/L胼酞嗪滴眼液点眼,对照组不注射NaIO3,用生理盐水点眼,皆为3次/d,连续点4wk,然后测ERGc波。结果：注射NaIO3后,高剂量组如30、40和60mg/kgNaIO3组的各种ERG波的振幅明显降低,低剂量组则变化不大。眼底彩照显示注射NaIO3后3d30mg/kg组出现部分视网膜坏死,视网膜坏死程度与注射后时间及注射量呈正相关,低剂量组没有明显改变。平片显示,注射NaIO3后3d30mg/kg组及更高剂量组单层RPE细胞出现坏死。组织学研究提示,注射NaIO330mg/kg组和低剂量组未发现明显变化。体外实验发现,浓度≥30mg/LNaIO3组RPE-19细胞增殖率降低。注射剂量为35mg/kgNaIO3后4wk,和对照组相比,NaIO3组大鼠ERGc波显著降低到对照组的31%（P〈0.01）。10g/L胼酞嗪＋NaIO3组和NaIO3组相比,大鼠ERGc波显著升高到对照组的50%（P〈0.05）。结论：NaIO3诱导的PRE细胞凋亡受剂量和时间的双重影响。剂量为30-40mg/kgNaIO3适用于非渗出型年龄相关性黄斑变性的体内造模。胼酞嗪可能延缓非渗出型年龄相关性黄斑变性的发展进程,可能用于治疗非渗出型年龄相关性黄斑变性。

AIM: To compare the effectiveness of needle-free incision suture closure with butterfly tape and traditional secondary suturing techniques in treating incision infection. METHODS: Two hundred and twenty-three patients with incision infection following hepatobiliary surgery at a tertiary hospital were randomly divided into three groups: 90 patients were closed by needle-free incision suture closure, which gradually closed the incision wound when drainage from incision infection was visibly decreased and healthy granulation tissues had grown; 79 patients were closed by butterfly bandage; another 54 patients were closed by traditional secondary suturing technique. Healing time of incision infection was calculated from the beginning of dressing change to the healing of the incision. RESULTS: Healing time in the needle-free incision suture closure group (24.2 +/- 7.2 d) was significantly shorter than that in the butterfly bandage group (33.3 +/- 11.2 d) and the traditional secondary suturing group (36.2 +/- 15.3 d) (P 0.05). CONCLUSION: Needle-free incision suture closure could gradually close the infection wound at the same time of drainage and dressing change, thereby shortening the healing time.

马克思主义女性主义视角下的《皮格马利翁》

吉林省教育学院学报 2018年第5期34卷 180-182页

作者：魏蔚安徽农业大学经济技术学院、安徽涉外经济职业学院安徽合肥230601

在《皮格马利翁》中,萧伯纳揭露了女性受到阶级压迫和经济压迫的本质——资本主义及其父权体系。萧伯纳认为只有消灭资本主义私有制,女性才可以得到真正的解放,而这一观点也与半个多世纪后的马克思主义女性主义的观点不谋而合。

Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and ***,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,*** investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel *** are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible *** with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported *** measures to prevent the introduction of the virus via cold-chain goods can be implemented.

目的:建立人载脂蛋白CⅢ(hApoCⅢ)转基因小鼠模型,探讨ApoCⅢ在代谢调节中的作用。方法:应用受精卵显微注射hApoCⅢ基因组片段方法制备转基因小鼠,筛选繁育出稳定遗传的转基因小鼠品系。通过血浆脂质检测、快速蛋白液相色谱脂蛋白分析、口服脂肪负荷试验、肝素后血浆脂蛋白脂酶活性测定以及葡萄糖耐量试验,分析转基因小鼠的脂质和糖代谢特点。结果:成功制备hApoCⅢ转基因小鼠并建立稳定表达的品系,该小鼠表现出显著的高甘油三酯血症[(401±39)mg/dLvs(83±9)mg/dL,P<0.01],并有随年龄增长的趋势。与非转基因小鼠相比,转基因小鼠对甘油三酯(TG)的清除显著延迟,且肝素后血浆脂蛋白脂酶活性也显著降低[(191±42)U/Lvs(368±42)U/L,P<0.05],糖耐量未改变。结论:hApoCⅢ转基因小鼠有明显的高甘油三酯血症,可能与血浆脂蛋白脂酶活性降低所致的血浆TG清除延缓有关。

Contemporary International Relations 2003年第4期13卷 1-6页

作者： Wang Zaibang Li Shaoxian Feng Zhongping Yuan Peng Sun Keqin Da wei Tang Zhichao 不详

Since the end of the war in Afghanistan, the United States has been intensely making preparations for military actions to overthrow the "Saddam regime. " Though there existed big differences between the pro-war factions and pro-peace factions in the United Nations, U. S. President george W. Bush vowed that his country "would take military actions against lraq as planned even if the UN Security Council fails to pass U. S. motion to topple the Saddam regime by force." This tells us that the second Persian Gulf War was inevitable. And people would naturally connect in mind this war with the first Persian Gulf War in 1991. What is the difference between the two Gulf wars? What follow-up move would Washington take after the second Gulf war? What impact would the war exert on the political structure of the Middle East? And what’s the prospect of relations among the big powers, especially among the United States, the European nations, Russia and China? To find answers to these questions, we invited Professor Wang Zaibang and six of his colleagues to have a panel discussion in early March. It should be mentioned that Contemporary International Relations held a discussion of similar kind in the No. 10 issue, 2002. This discussion can be seen as a follow-up to the last one. We hope it would better our readers’ understanding of how the Chinese view this issue of public attention.
