T

raditional Chinese medicine (TCM) has a long history and rich experi-

ences in treating cirrhotic ascites and nowadays is widely applied in

clinical practice as a complementary and alternative approach. XZT, a tradi-

tional Chinese herbal cataplasm, has been shown to be effective in treating

cirrhosis-associated ascites in clinical practice. XZT composed of Dahuang

(

Rheum palmatum L

), Laifuzi (

Raphanus sativus L

), Gansui (

Euphorbia kansui

TN Liou ex TP Wang

), Chenxiang (

Aquilaria sinensis (Lour) Gilg

), Dingxiang

(

Eugenia caryophyllata Thunb.

), Bingpian (

Borneolum syntheticum

) and Shex-

iang (

artificial Moschus

). In trying to uncover the working mechanism of such

combined system, we used a metabolomics-based systematic strategy to

trace the molecular basis as well as the pharmacokinetic behavior of XZT. Our

results revealed that the peak plasma concentrations and bio availabilities of

the active ingredients were significantly increased in rats with cirrhotic asci-

tes, thus proving the rationality of external XZT therapy. Metabolomics study

demonstrated that XZT mediated synergistically abnormalities of amino acid

metabolic pathways in cirrhotic rats. Biomarkers identified in the metabol-

ic profiling were validated through targeted quantitative analysis and by the

results from serum and urine. We found that regulation of L-arginine/nitric

oxide (NO) pathway was the most important mechanism of XZT to improve

the gastrointestinal motility of cirrhotic rats. This effect of XZT has been con-

firmed by the inhibition of inducible NO synthase and neuronal NO synthase

activities in the small intestine. This work gave a valuable insight into the

mechanism of XZT and provided an effective way to elucidate the mecha-

nisms of combined therapeutic systems.

Nianping Feng is currently full Professor and the

Director of the Department of Pharmaceutical Sci-

ences at Shanghai University of Traditional Chinese

Medicine. He received his PhD degree from China

Pharmaceutical University in June 1997 and was an

Assistant Research Professor at the same university

prior to joining the Shanghai University of Traditional

Chinese Medicine in Oct. 1998. He worked as a Senior

Scientist at Purdue University fromSept. 2012 to Sept.

2013. His research interests include novel drug deliv-

ery systems, pharmaceutical nanotechnologies and

TCM-based new drug development. He has published

more than 100 peer-reviewed articles and book chap-

ters and holds 11 patents.
