| + | <p>We chose <i>E. coli</i> Nissle 1917 as the main chassis to take effect in our project. <i>E. coli</i> Nissle 1917 has a history of 100 years as a licensed medicinal probiotic and is one of the most intensively investigated bacterial strain used in a probiotic preparation today. Its biosafety and effect have since been extensively shown in numerous trials<sup>[1]</sup>. Neither the gene of prominent virulence or the production of toxins have been found in Nissle 1917 and this strain also has proven to lack immunotoxic properties<sup>[2]</sup>. What’s more, Nissle has the ability to express several fitness factors, such as microcins, adhesins and iron uptake systems that facilitate their colonization within the host<sup>[3]</sup>. In addition, Nissle is in Group 1 and has been handled properly in the Safety Level 2 laboratory. To summarize, Nissle 1917 proves to be the perfect chassis for our project. Unfortunately, due to the limited time, we only verified the designed polypeptide chain can be expressed and function normally in <i>E. coli</i>. We hoped to consummate experiments Nissle 1917 in the future.</p> |

− | <p>To deprive of the survivability of engineered Nissle in the environment when excreted from the human intestine, we introduced the first Kill Switch. The first Kill Switch is a cold triggered Kill Switch, consisting of a toxin-antitoxin system as a major functional part and an RNA thermometer to regulate it.

| <p>Given the outbreak of the COVID-19 pandemic, we made extra efforts to protect ourselves and our communities. We strictly complied with all guidance from our university and local government the whole time. The first thing we ought to consider was to guarantee team members’ own health and safety. On account of no admittance to campus by the university, we converted our meetings to online remote conferences. Members that got back to school to carry out wet lab experiments have obtained the permission of the university. Though our university is located in a very low-risk area, we wore masks carefully whenever in public occasions to prevent infection. In the meantime, the physical condition of every team member was closely monitored by the “Hello Fudan” applet.</p> | | <p>Given the outbreak of the COVID-19 pandemic, we made extra efforts to protect ourselves and our communities.

In integrated human practice, we used an online questionnaire to investigate the public about osteoporosis awareness and calcium absorption. To better access the old, our target group, considering their weakness and lack of internet skills, we guide the young to help the aged in their family finish it. Besides, we use e-mails to connect with the osteoporosis field clinician and relevant professors, changing face-to-face interviews with the WeChat voice call. Aiming to engage current osteoporosis issues, we investigated published surveys, combining them with the 2018 China guideline for diagnosis and treatment of senile osteoporosis to analyze the current situation. We cooperate with Tianjin university Team for education, creating an online life science summer camp for middle school students. To avoid public education events, we design an online audio course and textbook to introduce basic biology knowledge.</p> | | <p>During this particular time, we especially emphasize social distancing and focus on online interactions.
