Attenuating properties of Agastache rugosa leaf extract against ultraviolet-B-induced photoaging via up-regulating glutathione and superoxide dismutase in a human keratinocyte cell line

Agastache rugosa Kuntze, known as a Korean mint, is an herbal medicine that has been used for the treatment of diverse kinds of symptoms in traditional medicine. This work was undertaken to assess the protective properties of A. rugosa leaves against UV-B-induced photoaging in HaCaT keratinocytes. They were evaluated via analyzing reactive oxygen species (ROS), promatrix metalloproteinase-2 (proMMP-2) and -9 (proMMP-9), total glutathione (GSH), total superoxide dismutase (SOD), cellular viability, flavonoid content and in vitro radical scavenging activity. Total flavonoid content of ARE, a hot water extract of A. rugosa leaves, was 22.8±7.6mg of naringin equivalent/g ARE. ARE exhibited ABTS+ radical scavenging activity with an SC50 of 836.9μg/mL. ARE attenuated the UV-B-induced ROS generation. It diminished the UV-B-induced elevation of proMMP-2 and -9 at both activity and protein levels. On the contrary, ARE was able to enhance the UV-B-reduced total GSH and total SOD activity levels. ARE, at the used concentrations, was unable to interfere with the cellular viabilities of HaCaT keratinocytes under UV-B irradiation. Taken together, ARE possesses a protective potential against UV-B-induced photoaging in HaCaT keratinocytes, possibly based upon up-regulating antioxidant components, including total GSH and SOD. These findings reasonably suggest the use of A. rugosa leaves as a photoprotective resource in manufacturing functional cosmetics.

Plasma amino acid profiling of cancer patients with abnormal Savda based on high-performance liquid chromatography

ObjectiveTo investigate metabolic signatures in plasma of cancer patients with abnormal Savda using plasma-free amino acid profiles, and to evaluate the diagnostic potential of these profiles for the detection and explanation of the mechanisms of different symptoms in traditional Uyghur medicine. MethodsPlasma samples from cancer patients with abnormal Savda (n=85) or non-abnormal Savda (n=105) and a healthy control group (n=65) were analyzed using high-performance liquid chromatography (HPLC). Orthogonal projection to latent structures with discriminant analysis was used for the classification and prediction of abnormal Savda, and spectral profiles were subjected to Student's t-tests to assess statistical significance. ResultsCompared with the healthy group, the levels of aspartic acid, glutamate, glycine, histidine, arginine, threonine, alanine, proline, methionine, isoleucine, leucine and phenylalanine decreased significantly in plasma of cancer patients with abnormal Savda (all P<0.05). Serine, cystine, tyrosine, valine and lysine levels showed no significant differences (all P>0.05). Compared with non-abnormal Savda syndrome patients, abnormal Savda syndrome patients showed high concentrations of glutamate, serine, valine, isoleucine, leucine and phenylalanine (all P<0.05). The remaining plasma amino acids showed no significant differences (all P> 0.05). ConclusionPlasma-free amino acid profiling has the potential to assist in understanding and determining abnormal Savda. A HPLC-based metabonomic platform could be a powerful tool for the classification of symptoms in traditional medicine.
