陈飞霞曰∶初起风关证未央，气关纹现急须防，乍临命位诚危急，射甲透关病势彰。
陈飞霞曰∶指纹何故乍然浮，邪在皮肤未足愁。腠理不通名表症，急行疏解汗之投。忽而关纹渐渐沉，已知
入里病方深。莫将风药轻相试，须向阳明里证寻。
陈飞霞说：小儿从满月到三岁，还不能进行脉诊；不是没有脉搏可以诊察，而是实际上虚弱与不虚难以确定。小儿常常害怕陌生人，初次见面难免啼哭叫喊，呼吸先变得紊乱，神志惊慌忙乱，此时脉搏的迟、数、大、小已经失去了本来的征象了，诊察它有什么益处？不如通过观察指纹的可见形态，与面色和病候相互印证。这也是医家中望诊和切诊相结合的意思。
让人抱着孩子，面对光线充足的地方站立。用左手握住孩子的食指，用我右手的拇指，推按孩子的三关部位。观察其颜色和形状，细心体会辨认，只要能辨别表里、寒热、虚实就足够了。世人喜欢标新立异，不在实处下功夫，认为这是浅显近俗的谈论，不屑于留意。不知道临证时如果能辨别这六种情况，就是最高明的医术。因为表里清楚，就知道病在经还是在腑，从而汗法或下法使用无误。寒热明确，就知道用寒药要避开热证，用热药要避开寒证，或者寒因寒用（以寒治寒的真寒假热证），热因热用（以热治热的真热假寒证），根据具体情况制宜，用药没有不当之处。虚实辨别清楚，就知道大虚证可能有盛实的假象，大实证可能有羸弱的假象，不被假症迷惑。凡是真虚和真实容易知道，假虚和假实难以辨别，真假既然明确，就没有犯“虚虚实实”（使虚者更虚，实者更实）的错误隐患。在这样的关键关头，如果不加以体会，却用不经之谈欺骗世人、蒙蔽世俗，说什么是什么是被人惊吓，什么是被牲畜惊吓，这不仅欺骗别人，而且欺骗自己，不仅对治疗无益，而且会误人性命，这是谁的过错呢？
陈飞霞说：初起风关证候尚未结束，气关出现纹路必须急加防范，刚到达命位确实危急，纹路穿透指甲直达指端则病势显露明显。
陈飞霞说：指纹为什么突然浮起？邪气在皮肤，不足为忧。腠理不通称为表症，急需行疏解之法，投用发汗药物。忽然间关部纹路渐渐沉伏，已知病邪入里，病情方深。不要将风药轻易尝试，必须向阳明里证寻求诊治。
Chen Feixia said: For infants from one month to three years of age, pulse diagnosis (pulse taking) cannot yet be performed; it is not that there is no pulse to diagnose, but rather that it is practically difficult to determine whether the condition is deficient or not. Infants are often afraid of strangers; upon first meeting, they inevitably cry and shout, causing their respiration to become disordered first, and their spirit and consciousness to become panicked and hurried. At this time, the slowness, rapidity, largeness, and smallness of the pulse have already lost their original characteristics. What is the benefit of diagnosing them? It is better to observe the visible patterns of the fingerprint (infant finger vein pattern) and corroborate them with the complexion and disease manifestations. This also embodies the combined meaning of inspection (observation) and palpation in medicine.
Have someone hold the child, standing opposite in a well-lit place. Use your left hand to grasp the child's index finger, and use your right thumb to push along the Three Passes (San Guan) of the child's finger. Observe its color and shape, carefully experiencing and recognizing it; being able to differentiate Exterior/Interior (Biao/Li), Cold/Heat, and Deficiency/Excess is sufficient. People nowadays like to seek novelty and do not work on solid foundations, regarding this as shallow and mundane talk, and disdain to pay attention to it. They do not know that if one can differentiate these six aspects during clinical practice, it constitutes the highest level of medical skill. Because if the Exterior/Interior is clear, one knows whether the disease is in the Meridians or the Fu organs, ensuring that sweating methods or purgative methods are used without error. If Cold/Heat is clear, one knows to use cold herbs while avoiding heat conditions, and use hot herbs while avoiding cold conditions, or to employ "treating cold with cold" (for true cold with false heat signs) and "treating heat with heat" (for true heat with false cold signs), adapting to specific circumstances so that medication is never inappropriate. If Deficiency/Excess is differentiated clearly, one knows that severe deficiency may present with excessive-sounding symptoms, and severe excess may present with emaciated-looking symptoms, preventing confusion by false signs. True deficiency and true excess are easy to know, while false deficiency and false excess are difficult to distinguish. Once true and false are clarified, there will be no danger of exacerbating deficiency with deficiency-inducing treatments or excess with excess-inducing treatments. At such critical junctures, if one fails to comprehend this, but instead deceives the world and fools the common people with unverified statements, claiming what constitutes fright by humans versus fright by animals, this not only deceives others but also oneself; it not only benefits no treatment but also endangers lives. Whose fault is this?
Chen Feixia said: When the Wind Gate (Feng Guan) syndrome initially appears and has not yet subsided, if the pattern extends to the Qi Gate (Qi Guan), urgent prevention is required; if it suddenly reaches the Life Gate (Ming Guan), it is truly critical; if it penetrates the nail joint and extends across the pass, the severity of the disease becomes manifest.
Chen Feixia said: Why does the fingerprint suddenly float? The pathogenic factor is in the skin and flesh, which is not worth worrying about. Impedance of the Cou Li (pores and interstitial spaces) is named an Exterior Syndrome (Biao Zheng); urgently apply dispersing and resolving methods, administering diaphoretic (sweat-inducing) prescriptions. If suddenly the patterns at the middle gate gradually sink, it is known that the pathogen has entered the Interior, and the disease is deep. Do not lightly experiment with wind-dispersing drugs; one must seek treatment based on Yangming Interior Syndromes.
