Abstract: Cyclophosphamide (CP) is a widely used chemotherapeutic agent that causes acute hemorrhagic cystitis. Although of the advanced prevention protocol, hemorrhagic cystitis is still a common and severe complication of the usage of cyclophosphamide. Ketamine, was originally synthesized for use as a dissociative anesthetics. The recreational use of ketamine has raised concerns worldwide. ketamine dependence leads to the development of LUTS that resemble interstitial cystitis. The pathophysiology of ketamine associated hemorrhagic cystitis has not been understood. Chinese herbal drugs have aroused much interest recently especially due to its superiority in the treatment of complicated disease. Gardenla Jasminoides Ellis is one component of Chinese traditional medication for the treatments of hemorrhagic cystitis. Several bioactive compounds have been found such as crocetin or geniposide.The vast number of metabolites typically present in natural products and their huge dynamic range results in the complex of many possibility bioactive natural compound. The capacity of metabolomics to measure numerous chemicals simultaneously and detect subtle differences among sample groups makes it a powerful discovery tool. Plant metabolomics deals with qualitative and quantitative analysis from plant and covers targeted metabolomics analysis, profiling and fingerprint. Ultra-performance liquid chromatography- tandem mass spectrometry (UPLC-tandem-MS) techniques and in the development of new multivariate data analysis methods have led to a giant leap in knowledge about the plant metabolomics and its response to systemic biology Metabolomics is a crucial tool for (1) identification of active compounds and quantitative prediction of bioactivity, (2) the identification of efficacy and action of herbal medicine, (3) evaluation of herbal biotransformation, (4) safety and toxicity of herbal medicine assessment. There are three parts in our study. In the first year, we have evaluated the traditional herbal decoction, the commercial extract of Gardenla Jasminoides Ellis and search the contents of bioactive constituents by UPLC-tandem-MS. Secondly, we will try a metabolomics approach base on UPL-C tandem- MS to characterize the metabolic profile associated with acute administration of cyclophasmide or chronic administration of ketamine-induced hemorrhagic cystitis. We will try to find the metabolic pathways and potential biomarkers related to hemorrhagic cystitis. Thirdly, we will assess the therapeutic effects and mechanisms of Gardenla Jasminoides Ellis in treatment of hemorrhagic cystitis. We will also apply the metabolomics approach to explore the safety and toxicity of Gardenla Jasminoides Ellis. Metabolomics provide a holistic alternative to tackle the challenges in identifying novel chemicals from Chinese herbal products and studying complex interactions between phytochemicals and biological system. This information can be used to identify novel and improved diagnostic and therapeutic targets that might prevent, or ameliorate the severe complications of acute usage of cyclophosphanmide or the chronic usage of ketamine induced hemorrhagic cystitis.
