RESUMO

BACKGROUND: Raw Moutan Cortex (RMC), derived from the root bark of Paeonia suffruticosa, and Processed Moutan Cortex (PMC) is obtained from RMC by undergoing a stir-frying process. Both of them are indicated for different pharmacodynamic action in traditional Chinese medicine, and they have been used in China and other Asian countries for thousands of years. OBJECTIVE: To establish a method to study the RMC and PMC, revealing their different chemical composition by fingerprint, qualitative, and quantitative ways. MATERIALS AND METHODS: High-performance liquid chromatography coupled with diode array detector and electrospray mass spectrometry (HPLC-DAD-ESIMS) were used for the analysis. Therefore, the analytes were separated on an Ultimate TM XB-C18 analytical column (250 mm × 4.6 mm, 5.0 µm) with a gradient elution program by a mobile phase consisting of acetonitrile and 0.1% (v/v) formic acid water solution. The flow rate, injection volume, detection wavelength, and column temperature were set at 1.0 mL/min, 10 µL, 254 nm, and 30°C, respectively. Besides, principal components analysis and the test of significance were applied in data analysis. RESULTS: The results clearly showed a significant difference among RMC and PMC, indicating the significant changes in their chemical compositions before and after the stir-frying process. CONCLUSION: The HPLC-DAD-ESIMS coupled with chemometrics analysis could be used for comprehensive quality evaluation of raw and processed Moutan Cortex. SUMMARY: The experiment study the RMC and PMC by HPLC-DAD-ESIMS couple with chemometrics analysis. The results of their fingerprints, qualitative, and quantitative all clearly showed significant changes in their chemical compositions before and after stir-frying processed. Abbreviation used: HPLC-DAD-ESIMS: High-performance Liquid Chromatography-Diode Array Detector-Electrospray Mass Spectrometry, RMC: Raw moutan cortex, PMC: Processed moutan cortex, TCM: Traditional Chinese medicine, PCA: Principal components analysis, LOD: Limit of detection, LOQ: Limit of quantitation, RSD: Relative standard deviation.

RESUMO

We report a rare case of a 38-year-old woman with metastatic colonic adenocarcinoma from primary lung adenocarcinoma detected by PET/CT. She underwent colonoscopy and adenocarcinoma was diagnosed in the pathology report, which was the same as that for lymph node biopsy from a left supraclavicular lymph node. We used immunohistochemistry to diagnose primary adenocarcinoma of the lung with colonic metastasis. Owing to mutation in exon 19 of EGFR gene, targeted therapy was given to her with a prescription of oral gefitinib for 1 month as first-line treatment. It was chosen to further treat the patient with chemotherapy and radiotherapy. As the patient was suffering from increasing coughing and sputum, radiotherapy and chemotherapy were subsequently cancelled. Since the general condition of the patient was relatively poor, Tarceva was therefore prescribed. The patient had lived for 5 more months since the diagnosis of metastatic colonic adenocarcinoma.
