In this review, the mechanism of borneol in promoting permeation by destroying the highly ordered lipid structure of the lipid layer and by destroying the hydrogen-bond network was described. The application of borneol in promoting the transdermal absorption of the active ingredients of traditional Chinese medicine and chemical drugs was introduced. The application of borneol as a natural ingredient added to functional cosmetics was summarized, and its effects on skin-spot treatment, acne skin care, eczema skin care, skin repair and anti-oxidation were introduced. Finally, the possible problems in the application of borneol in cosmetics were put forward, and the application prospect of borneol in the development of cosmetics was given.展开更多
目的观察C57BL/6N-Tg(1.28HBV)/Vst乙型肝炎病毒(hepatitis B virus,HBV)转基因(HBV-Tg)小鼠模型的特征,并分析HBV-Tg小鼠模型的转录组学特点。方法以10只雄性HBV-Tg小鼠为实验组,10只野生型小鼠为对照组。以血清HBV DNA、HBsAg、HBeAg...目的观察C57BL/6N-Tg(1.28HBV)/Vst乙型肝炎病毒(hepatitis B virus,HBV)转基因(HBV-Tg)小鼠模型的特征,并分析HBV-Tg小鼠模型的转录组学特点。方法以10只雄性HBV-Tg小鼠为实验组,10只野生型小鼠为对照组。以血清HBV DNA、HBsAg、HBeAg水平和肝组织HBsAg、HBcAg表达情况评价模型小鼠病毒学特征,检测血清ALT、AST,肝组织HE、天狼猩红染色及肝组织Hyp含量评估小鼠肝脏炎症及纤维化程度。两组各随机选择3例肝组织样本提取RNA进行高通量转录组测序。经R软件分析获得表达显著的差异基因,经GO和KEGG分析获得差异基因功能富集情况,再采用实时荧光定量PCR(RT-qPCR)对差异显著的基因进行验证。结果与正常组相比,模型组ALT、AST水平均有所升高,以ALT更为显著(P<0.05);模型组肝组织HE染色可见肝细胞核增大,个别肝细胞出现肿胀。天狼猩红染色结果显示,HBV转基因组汇管区及小叶间出现少量胶原沉积,呈细线状。通过筛选条件(|logFC|>2倍且P.adj<0.05)获得差异基因共计1352个,其中上调基因703个,下调基因649个。KEGG分析提示差异基因主要在PPAR信号通路、视黄醇代谢、脂肪酸降解等通路中富集(P.adj<0.05)。明显上调的差异基因主要有Cyp4a10、Cyp4a14、Acot1、Acot3、Ehhadh等,明显下调基因包括Scn5a、Apol10b、Igddc4、Cxcl1、9530077C05Rik等,经RT-qPCR验证趋势一致(P<0.05)。结论HBV-Tg小鼠具有自发纤维化的趋势,经转录组学分析,慢性乙型病毒性肝炎(chronic hepatits B,CHB)发生的潜在机制主要涉及PPAR信号通路、视黄醇代谢、脂肪酸降解、药物代谢等通路。展开更多
