#青年美医进阶计划##微博健康公开课# 2022年2月16日，发表在《Proceedings of the Royal Society B: Biological Sciences》上的一项题为“More than just a pretty face? The relationship between immune function and perceived facial attractiveness”的研究发现，脸蛋儿长的越有吸引力的人，免疫功能越强健，特别是在细菌免疫方面。
这项新研究涉及了159名平均年龄20岁的年轻参与者，其中79名为女性。所有参与者都提前接受了检测，以确保没有慢性病史，非抑郁和其他精神疾病、非肥胖和参加研究前2天不使用类固醇和抗炎药物，不运动、不饮酒。
参与者的照片由另外492名平均年龄25岁的参与者（其中259名为女性）在网上调查中进行了吸引力评级。在给参与者拍完照片后，研究人员还对每个参与者进行了一系列检查，以评估他们的免疫系统状态、身体炎症水平和自我报告的健康状况。
在分析这些结果时，研究人员发现那些被评级为长相有吸引力的人具有相对健康的免疫功能，特别是在细菌免疫方面。
有趣的是，参与者中较高的炎症水平和吸引力之间没有联系。这可能表明，与急性疾病的迹象相比，面部吸引力是免疫系统强健的一个更好的代表。
简而言之，面部吸引力的主要作用可能不是为了避免一个生病的伴侣，而是为了避免一个可能会影响你未来后代健康的伴侣。

Liquidity
The current ratio and quick ratio of T Zhou’s business were 2:1 and 1.33:1 respectively.Both ratio indicated the liquidity of T Zhou’s business was good and healthy.It can be seen that even if the inventory cannot be liquidate, it will not affect the company's short-term repayment ability.

Liquidity

Despite the gross profit ratio of two business are same, K Kung’s business was more profitable, as reflected by its net profit ratio and higher return on capital employed .it’s higher mark-up(I.e. higher gross profit ratio)and lower expenses-to-sales ratio(i.e. higher net profit ratio)made it more profitable. This indicated that the company was more efficient in minimizing its operating expenses and for every $100 of long-term capital investment made in the business, more operating profit.

Liquidity
The current ratio and quick ratio of Keith’s firm were 4:1 and 2:1 respectively. The current ratio and quick ratio of Nelson’s firm were 2:1 and 1.02:1 respectively.
Keith’s firm was more liquid, as reflected by its higher current ratio and quick ratio.
Nelson’s firm was less liquid than Keith’s firm. Its current ratio and quick ratio were lower than Keith’s firm. Keith’s firm might have difficulty meeting its short-term financial obligations if these ratios keep falling.
