The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.

Objective To investigate the clinical value of FDG PET imaging in the follow up of nasopharyngeal carcinoma after radiotherapy. Methods Twelve patients with nasopharyngeal carcinoma underwent FDG PET, CT and/or MRI during the follow up of 12 18 months after radiotherapy. The results of FDG PET were double blind evaluated and compared with these of CT and MRI. The recurrent lesions in six of these patients were pathologically confirmed and six by CT scan. Results Nine of 12 patients did not show any recurrence by CT and MRI scans. However, FDG PET scans showed significantly increased FDG metabolism, indicating recurrence in 3 of these patients. In 2 patients, both CT/MRI and FDG PET indicated recurrence. The remaining one patient had radiotherapy induced cerebral necrosis. He was misdiagnozed as an intracranial recurrence by MRI, but FDG imaging was negative. Conclusions FDG PET imaging has an advantage in distinguishing the relapse or necrosis in the follow up of post radiotherapy nasopharyngeal carcinoma patients. PET, CT and MRI is able to give a detail both in morphological and functional changes of disease. They are especially useful in the follow up or the set up of treatment planning for recurrent nasopharyngeal carcinoma.

Objective: To detect tumor cells in the peripheral blood of patients with breast cancer by usingthe MAGE-A1 and MAGE-A3 genes as specific tumor markers. Methods: Peripheral blood was obtained from 40 patients with breast cancer and 20 patients with benign diseases. The mRNA of the MAGE-A1 and MAGE-A3 genes in the peripheral blood mononuclear cells (PBMC) was detected by nested RT-PCR. The MAGE-A1 and MAGE-A3 transcripts in breast cancer were detected by RT-PCR. Results: Of the 40 breast cancer patients, MAGE-A1 and MAGE-A3 mRNA were positive in 12.5% (5/40)and 17.5%(7/40)of PBMC, respectively, and in 15.0 %(6/40)and 22.5 %(9/40)of breast cancer tissues, respectively. In the PBMC of the 40 breast cancer patients, 10(25.0%)samples were detected to express at least one type of MAGE mRNA. MAGE mRNA were not detected in the PBMC from the patients whose tumors did not express the MAGE genes, nor in the PBMC from the 20 patients with benign diseases. The positive rate of MAGE mRNA in the PBMC was closely correlated with the TNM stages. Conclusion: MAGE-A1 and MAGE-A3 mRNA could be specifically detected in the PBMCof breast cancer patients by our methods. They may be used as specific tumor markers for the detection of the circulating breast cancer cells.
