Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Currently researches on NAFLD patterns based on metabolomics were limited. Our study was undertaken to investigate the correlation of TCM patterns and metabonomics, to evaluate the application of urinary metabonomics in NAFLD: whether it can be used in TCM patterns auxiliary classification of NAFLD. In addition, the investigators also aim to discover novel biomarkers for the noninvasive early diagnosis of nonalcoholic fatty liver disease (NAFLD).
In this study, urine samples from humans of three divided groups (healthy controls, the group of "liver depression and spleen deficiency" pattern and group of "damp-heat in the interior pattern) were collected, then 4℃, 15 min 3000 rpm centrifuged and - 80℃ cryopreserved. The metabolic profile changes were analyzed by Gas Chromatograph-Mass Spectrometer(GC/MS) with principal component analysis (PCA), partial least squares-discriminate analysis (PLS-DA) and orthogonal partial least squares-discriminate analysis (OPLS-DA). Furthermore, biochemical examination were also carried out to compare among these three groups.
Base on literature survey, the investigators inferred that there should be metabolic differences between the two patterns of NAFLD. If the investigators hypothesis is correct, the investigators can find different metabolites which can be used discriminate between NAFLD and healthy population, different patterns through urinary metabonomics.
The results will be attractive which mean a lot: it will prove the importance of the four diagnosis methods of TCM used in differential analysis by metabonomics; it will validate the classification of TCM syndromes is scientific; it will shed light in the study of TCM syndromes; it will find biology markers to help diagnosis, treatment and pattern discrimination.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
2. The patients will fill in a syndromes questionnaire for TCM information.
3. Based on the symptoms, tongue and pulse conditions by four diagnostic information, the NAFLD patients will be randomized into the group of "liver depression and spleen deficiency" pattern and group of "damp-heat in the interior" pattern.
4. Then urine samples of the patients will be collected.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy people
This group contains healthy people only whose liver function and B ultrasound are normal.
No interventions assigned to this group
group of "liver depression and spleen deficiency" pattern
In this group, patients are considered to be the pattern of "liver depression and spleen deficiency". They mainly have the symptoms of loose stool, depression, fat tongue with white coating and teeth marks and soft or string pulse.
No interventions assigned to this group
group of "damp-heat in the interior" pattern.
In this group ,NAFLD patients have symptoms with dry mouth, bitter mouth, heavy feeling in legs, yellow urine, reddish tongue with thick yellowish coating and slippery pulse.
No interventions assigned to this group
