The development of traditional Chinese medicine (TCM) in the plateau area is relatively backward. There is a lack of system to analyze the effects of the special environment of plateau low pressure and hypoxia on human meridians qi and blood, as well as the etiology and pathogenesis of plateau hypoxic diseases. To analyze the composition rules of anti-hypoxia TCM formulation with data mining methods.

METHODS

The experimental literatures related to high altitude hypoxia were searched in China National Knowledge Infrastructure (CNKI), Wanfang Med Online, VIP, China Biology Medicine disc and other databases, a standardized prescription database was established after screening and standardization of prescription data in the literature. The composition rules of these prescription including drug frequency, drug attributes, drug efficacy, drug combination, and core prescription were analyzed and displayed with visual charts.

RESULTS

A total of 135 TCM prescriptions were included, and 229 flavored drugs were included. Among these prescriptions, the TCM with high frequency of use were Astragalus, Danshen, Ginseng, and Angelica, etc. Four natures of the TCM were mostly warm and calm. Five flavours of the TCM were mostly sweet, bitter, and pungent. And channel tropism of the TCM mostly entered the heart, lung, and liver meridians. The frequency combination of TCM was Astragalus-Danshen and Astragalus-Angelica. The core medicines of these prescriptions were Astragalus, Danshen, Angelica, Rhodiola, Goji, and Ginseng. TCM could alleviate symptoms such as chest tightness, chest pain, coughing and wheezing, coughing, vomiting, fatigue, and loss of appetite caused by hypoxia at high altitude.

CONCLUSIONS

Through data mining, it is concluded that the prevention or treatment of plateau hypoxic diseases mostly utilized products can nourish blood, replenish qi and dispel stasis, and help yang and dispel qi, most of them are compatible with qi tonic drugs and blood circulation and stasis dissolving drugs, and pay attention to the combination of virtual and real, yin and yang.
