简介：摘要传统的免疫共沉淀测序（ChIP-seq）是研究蛋白-染色质相互作用的主流方法，由于ChIP-seq难以在低起始细胞量和单细胞样本上实施限制了其应用范围。近年来新发展起来的染色质酶切测序技术CUT&RUN和CUT&Tag展现出操作简单，背景低，可重复性高和要求的细胞起始量低等优点，有替代ChIP-seq进行蛋白-染色质相互作用研究的潜力，并有效提高了单细胞ChIP-seq的可行性。本文将就这类靶向染色质进行酶切测序的主要技术的发展和应用现状做简要综述。

简介：AbstractTrauma during pregnancy deserves special attention because of its management objectives, i.e. wellbeing of both pregnant woman and foetus. Maxillofacial trauma directly affects the nutrition of foetus by interfering with the normal functions in a pregnant woman such as mouth opening, mastication and breathing. Hence early restitution of form and function of maxillofacial skeleton is essential. However, the gravid status is associated with numerous anatomical and physiological changes which present with clinical dilemma related to imaging and treatment. A careful scrutiny of the patient's systemic and gestational status is absolutely essential before, during and after instituting any interventional procedures. We present a case of bilateral condyle fracture in a 30-year-old pregnant woman in the third trimester (32 weeks). She was treated with inter maxillary fixation using orthodontic brackets & elastics. After successful restitution of occlusion, the patient was advised aggressive physiotherapy which ensured normal mouth opening. Two weeks later, the patient delivered uneventfully. The patient was followed up at one month and 3 month and demonstrated restitution of normal occlusion, mouth opening and lower facial height. This article aims at analyzing the contemporary principles in management of maxillofacial trauma in a pregnant woman and clarifying the common misconceptions.
