The time needed for the development of flies fed with the Beijing Recipe is longer than that of flies fed with Wurzburg Recipe . The former showed hyperfunction in courtship, less female fertility, and lower performance indices compared with those of fed with B.

用北京配方培养的果蝇发育时间比用Wurzburg配方的果蝇延长，A培养基培养的果蝇在求偶方面表现出亢进，雌蝇单位时间内的产卵率低于B培养基中的果蝇，而且A培养基培养的果蝇学习记忆能力低于B培养基中的果蝇。

Patients undergo major surgery may develop malnutrition because of reduce intake result from hypermetabolism and metabolic dysfunction. Artificial nutritional support is essential for these patients in order to decrease the susceptibility to infection, enhance wound healing and shorten the ventilation days and hospital stay.

外科手术或创伤患者常因疾病本身及手术形式等因素影响进食，而创伤所造成之伤害也会使身体产生异化作用及营养素代谢上的功能不良，容易造成病人营养不良的发生，并因此延迟伤口愈合时间、增加病人感染的机率、延长呼吸器脱离时间及住院天数；因此临床上建议对创伤患者宜及早给予适当的营养支持。
