痤疮是一种常发于青春期的慢性炎症性皮肤病,在青少年人群中普遍存在,为患者身心健康带来较大影响。根据《临床皮肤科杂志.2019.48(9):583-588.》中数据显示中国人群截面统计痤疮发病率为81%。3%7%痤疮患者会遗留瘢痕。而目前有许多患者在得了痤疮后并没有及时到医院进行临床诊断,而临床医师对痤疮治疗的选择存在很大差异,有些治疗方法疗效不确定,缺乏循证医学证据支持,个别方法甚至可能对患者造成损害。

Acne is a chronic inflammatory skin disease that often occurs in adolescence and is prevalent in the teenagers, bringing a great impact on the physical and mental health of patients. According to the Journal of Clinical Dermatology.2019.48(9):583-588, the prevalence of acne in the Chinese population is 81% in cross-section. 3% to 7% of patients with acne will be left with scarring. At present, there are many patients who do not go to the hospital for clinical diagnosis in a timely manner after having acne, and clinicians' choices of acne treatments vary greatly, with some treatments having uncertain efficacy, lacking evidence-based medical evidence to support them, and individual methods may even be damaging to patients.

Acne can be caused by a variety of reasons, including excessive secretion of androgens and sebum, abnormal keratinization of the follicular cortical gland ducts, and the proliferation of Propionibacterium acnes in the hair follicles. According to incomplete statistics, many adolescents are under pressure from schoolwork, anxiety, etc., which can also subconsciously affect the endocrine function and lead to acne, and many acne sufferers are also anxious about the change in appearance caused by acne itself. Therefore, it is important to treat acne.

痤疮的产生有种种原因,主要以雄性激素及皮脂分泌过多、毛囊皮质腺导管的角化异常和痤疮丙酸杆菌在毛囊内增生是痤疮发病的主要原因。而据不完全统计,很多青少年因为课业压力过大,产生焦虑情绪等也会潜移默化地影响内分泌功能导致产生痤疮,而痤疮的患者也有很多还会对痤疮本身而导致容貌改变感到焦虑。因此,对于痤疮的治疗迫在眉睫。

经过我们对目前市面上痤疮相关护肤品的调查,大部分产品采用物理和化学方法对痤疮进行缓解,而我们采用了生物技术,运用工程菌支撑了更加天然的痤疮缓解产品。我们相信这种新颖、方便的技术将为市场带来新的变化,并带来巨大的社会和经济效益。

通过查找文献我们了解产生痤疮的主要原因之一是由于痤疮丙酸杆菌在毛囊中大量分泌卟啉引发炎症所以如果我们能减少卟啉便可以抑制炎症从而减少痤疮的产生。根据我们查阅的文献【卟啉和维生素b12在脸上的常驻菌群的合成通路有共同的中间产物place如果我们能让中间产物尽可能合成为维生素b12这样便可以减少卟啉的产生。注意到一类细菌可以吸收维生素b12我们决定使用一种普遍存在于人体的细菌——大肠杆菌来作为我们的底盘细菌。通过导入VB12转入蛋白基因使其吸收面部的VB12从而迫使常驻菌群为了维持稳态而将中间产物尽可能合成缺乏的维生素b12进而减少卟啉的合成【拮抗】抑制痤疮。 同时我们导入了VB12转出蛋白基因从而使大肠杆菌在吸收完面部的VB12后可以进行回收并导出以便用于对VB12的再利用 *当然,我们也向工程菌中导入了自杀系统以保证其不会对环境产生危害。】
