Application of tri-operators breast blood oxygen imaging to diagnose breast cancer / 中华内分泌外科杂志

Objective To use tri-operator breast blood oxygen imaging in diagnosis of early stage breast cancer.Methods To analysis and diagnosis eighty cases with the technology of breast blood oxygen imaging.Results The accurate rate of the diagnosis made by technology of breast blood oxygen imaging was 93.75%,the sensitivity of diagnosis was 90.63%,the specificity was 95.83%.Conclusions The technology of breast blood oxygen imaging without the radiation may be a better methods to diagnosis the breast diseases,which has the higher sensitivity than infrared rays examination on breast cancer diagnosis.

Studies of Active Constituents with Analgesic and Antemetic Actions from Rhizoma Alpiniae Officinarum / 广州中医药大学学报

ive] To isolate the active constituents with analgesic and antemetic actions from Rhizo-ma Alpiniae Officinarum. [Methods] Polyamide and silica gel column chromatography was used to isolate and extract the analgesic and antemetic constituents. The structure of compounds was identified by ultra violet spectroscopy, infrared spectroscopy, mass spectroscopy and nuclear magnetic resonance spectrosco-py. [ Results ] Galangin and kaempferide are identified as the analgesic and antemetic constituents. [Conclusion] Galangin can be used as the quality control for Rhizoma Alpiniae Officinarum.

Effect of Ligustrazine on the Intracellular Translocation of Smad Protein in HSC-T6 Cell Line / 中药新药与临床药理

Objective To investigate the effect of ligustrazine on the intracellular translocation of Smad protein in HSC-T6 cell line.Methods HSC-T6 cell was cultured with ligustrazine at the dose of 10-5 mol/L in the culturing dish for 2 hours.After the culturing,the translocation of Smad-2 and Smad-4 proteins was detected by immunofluorescence assay.Results There was no evidence of the translocation of Smad-2 and Smad-4 proteins in HSC-T6 cell after the culturing.Conclusion Ligustrazine can block the signal pathway of TGF-?/Smad,which may be one of its important mechanisms of inhibiting the proliferation of HSC-TS cell.

On GC Fingerprint of Rhizome of Aplinia Officinarum (Gao Liang Jiang) and Its Congeners / 中药新药与临床药理

Objective: The characteristic smell of the rhizome of Aplinia officinarum is key criteria for quality evaluation by TCM empirical practice. The aim of this study focused consequently on the GC fingerprint of its volatile oil. Method: Gas chromatographic experiment was carried out, and the GC fingerprint was generated. Results: The GC fingerprints of the authentic samples and the commercial samples collected from various sources expressed very close similarity and its congeners can be easily distinguished each other.
