Cognitive dysfunction is the main manifestation of aging,which has become a hot topic of global concern as aging inten-sifies.This article proposes that essence is the origin of life,qi is the driving force of life,and spirit is the embodiment of life.Guided by the qiluo theory of essence,qi,and spirit,the key pathogenesis and corresponding treatment methods of cognitive impairment caused by aging are proposed:kidney essence deficiency and brain marrow insufficiency are the fundamental,primordial qi deficiency and brain meridian obstruction are the key,brain spirit dystrophy and spirit activity dysfunction are the manifestations;the treatment is to tonify the kidney and essence to fill brain marrow,warm and nourish primordial qi to unblock brain meridians,enhance brain sprit to improve spirit activity,expecting to be beneficial for delaying and preventing aging-caused cognitive impairment.

Qi and blood are the two cornerstones of the theoretical system of traditional Chinese medicine.Luobing theory con-structs an academic system with the prominent characteristics of"Qi-blood correlation"to guide the prevention and treatment of compli-cated diseases of internal injury and severe external diseases.Qi is the leader of blood,blood is the mother of Qi,qiluo runs meridian qi,mailuo runs blood,and the relationship between qiluo and mailuo is essentially a dialectical relationship between Qi and blood.Qi and blood play a role in the regulation of collaterals,warming and nourishing,blood supply and Qi supply,and the exchange of Jin and blood.The normal structure and function of collateral vessel is the key factor to maintain the normal structure and function of the viscer-a.The collateral vessel entering the viscera is the collateral of the viscera,and entering the heart is divided into the mailuo of the heart and the qiluo of the heart.Cardiac mailuo infiltration can nourish the heart tissue and provide material basis for maintaining the struc-ture and function of the heart,which is identical with the modern medical coronary system and cardiac microvessels;qiluo regulates cardiac function,maintains cardiac systolic pulsation,and has the same identity with cardiac conduction system and regulatory mecha-nism.The interaction of mailuo disease and qiluo disease can lead to arrhythmias,such as coronary heart disease arrhythmias and pri-mary arrhythmias.According to the therapeutic principle that collateral vessels work by circulation,the key to the treatment of arrhyth-mia is to unobstruct the collateral veins and harmonize Qi and blood,which has important guiding value for the treatment of arrhythmia.The treatment of arrhythmias should not only remove pathogenic factors and improve cardiac conduction function,but also protect cardiac microcirculation,especially for arrhythmias without clear organic disease,which provides a new idea for the prevention and treatment of arrhythmias by combining traditional Chinese and Western medicine.
