朱丹溪所著《格致余论》中有观点:“天之阳气为气,地之阴气为血。故气常有余,血常不足”,气属阳而血属阴,故可延伸为“阳常有余,阴常不足”,并提出了滋阴降火的治法。后世诸多医家在诊疗的过程中观察到,诸多长期失眠患者会伴随出现心烦,手足心热,头晕耳鸣,心悸健忘,颧红潮热,口干少津,舌红少苔,脉细数等表现,属阴虚证,如未及时干预,易化生火热,故而常结合朱丹溪之滋阴降火法治疗。在历史前进的过程中,滋阴降火法的运用也在不断的发展。文章对于滋阴降火法治疗阴虚火旺型失眠的研究进展展开综述,归纳治疗滋阴降火法的方药及针刺研究,总结其治疗失眠的独特之处,为中医治疗失眠提供良好的依据。

目的探讨脂多糖(LPS)联合D-半乳糖胺(D-GaIN)诱导急性肝损伤小鼠中TMEM88的表达变化,并研究TMEM88表达高低对LPS诱导的AML-12细胞炎症因子分泌的影响。方法体内,将20只小鼠按随机数字表法随机分为正常组与模型组,每组10只,模型组采用LPS/D-GaIN联合诱导,收集小鼠肝脏组织和血液。体外,AML-12细胞经LPS刺激及TMEM88转染,测定TMEM88及炎症因子的表达变化。结果模型组小鼠肝脏组织发生明显损伤,ALI模型造模成功率为80%。此外,模型组小鼠肝脏TMEM88表达水平均明显升高(P<0.05)。在AML-12细胞中,LPS刺激的最适条件为100 ng/mL,刺激24 h。pEGFP-C1-TMEM88和TMEM88-siRNA经验证成功转染进LPS刺激的AML-12细胞内(P<0.05)。此外,TMEM88过表达会导致炎症因子IL-1β、IL-6及TNF-α分泌上调(P<0.01),而敲低TMEM88则会减少炎症因子的分泌(P<0.05),以上实验结果表明TMEM88的表达水平可能影响炎症过程。结论TMEM88的表达水平在LPS/D-GaIN诱导的急性肝损伤模型中具有重要作用。

A novel N, O modified Mn_(3)O_(4)@porous carbon catalyst(NOC-Mn_(3)O_(4)) was prepared by direct carbonization using the manganese-metal organic framework(Mn-MOF) and covalent organic framework(COF) as precursors to activate peroxymonosulfate(PMS) for the degradation of bisphenol A(BPA) and rhodamine B(Rh B). Benefiting from the N and O co-doping of COF, larger specific surface area, faster electron transfer and Mn cycling, the optimum 1NOC-Mn_(3)O_(4)could significantly improve the degradation performance of BPA and Rh B(92.1% and 96.9% within 30 min) as compared to C-Mn_(3)O_(4)without COF doping. In addition, 1NOC-Mn_(3)O_(4) showed good reusability and strong anti-interference ability. Radical quenching experiments, X-ray photoelectron spectroscopy(XPS), Electron paramagnetic resonance spectrometer(EPR) and electrochemical tests showed that the 1NOC-Mn_(3)O_(4)/PMS system degraded BPA and Rh B by both radical and non-radical pathways. Moreover, the possible degradation pathways of BPA and Rh B were proposed by liquid chromatography-mass spectrometry(LC-MS). Except for that, the toxicity of BPA, Rh B and their intermediates were evaluated. This study opens up a new prospect for the design of COF-doped PMS catalysts.
