[Plasma amino acid profiling of "same symptom for different disease" in Uyghur medicine based on high-performance liquid chromatography].

OBJECTIVE

To determine the plasma amino acid metabolism of "same symptom for different diseases" in different cancer patients in Uyghur medicine.

METHODS

Plasma amino acid concentration was tested by high-performance liquid chromatography (HPLC) in cancer patients with different symptom, and the spectral profiles were subjected to a t-test for statistical significance.

RESULTS

Compared with the healthy group, lung cancer, cervical cancer, breast cancer and gastric cancer patients with abnormal Savda had lower concentration of plasma amino acids except some amino acids. Lung cancer patients with abnormal Savda had higher concentration of plasma phenylalanine, serine, cystine, valine, isoleucine, leucine and aspartic acid than Unsavda patients (P<0.05). Cervical cancer patients with abnormal Savda had low concentration of plasma arginine, but higher concentration of plasma cystine than Unsavda patients (P<0.05). Breast cancer patients with abnormal Savda had higher concentration of plasma leucine, serine, taurine, cystine, tyrosine, valine, isoleucine and asparagine than Unsavda patients (P<0.05). Gastric cancer patients with abnormal Savda had high concentration of plasma cystine but lower concentration of plasma phenylalanine, threonine and arginine than Unsavda patients (P<0.05).

CONCLUSION

Different tumor patients with abnormal Savda have common characteristics and significant differences.
