[Epidemic survey on TCM syndrome typing and preliminary discussion on TCM etiology and pathogenesis of fatty liver].
OBJECTIVE
To investigate the common TCM syndrome types of fatty liver by way of epidemic questionnaire, their occurrence ratio, and the correlation between various syndrome types and objective indexes.


METHODS
A total of national wide 503 subjects with fatty liver were enrolled, the TCM syndromes, body mass index (BMI), abdominal perimeter/hip circumference, liver function, blood lipids, B ultrasonic examination and CT in them were observed and recorded.


RESULTS
In the 46 symptoms investigated in total, the first ten symptoms in order of appearing rate were lassitude, obese, oral dryness, vertigo, hypochondriac distending pain, soreness and pain in loin, spiritlessness, oral bitterness, aching and weakness in knee and abdominal distention. The mostly appeared tongue figures were pale and corpulent or pale dim tongue proper, white greasy or yellow greasy tongue coating, and the mostly appeared pulse figures were taut, taut-thin and taut slippery. Statistical cluster analysis showed that syndromes of fatty liver could be typed into 4 TCM types, the asthenia Pi-Shen with Gan-stagnation type, the asthenia Pi-Shen type, the asthenia Pi with phlegm-heat type and the unclassified type. Among them the asthenia Pi-Shen with Gan-stagnation type was the commonest one, which accounted to 62.32%.


CONCLUSIONS
The mostly appeared syndrome type of fatty liver was asthenia Pi-Shen with Gan-stagnation type. The TCM pathogenesis of fatty liver was deficiency of origin, mainly deficiency of Shen, involving Pi, with excess superficiality, the turbid-phlegm and blood stasis.
