Detection of serum tumor markers in clinical application is simple,which has become an in dispensable means in clinical medical work,and played an important role in the early detection of malignant tumor,benign and malignant tumor differential diagnosis,guiding the stage and predicting prognosis.But because of its sensitivity and specificity have limitations,we should find more new markers.

Objective: To explore the effects of Polygonatum odoratum on body based on metabonomics.
Methods: The ultra performance liquid chromatography coupled with mass spectrometry (UPLC-MS) and principle component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were used to evaluate the changes of endogenous substances in rats after intragastric administration of Polygonatum odoratum.
Results: Significant differences between the control group and administration group were observed in PCA and OPLS-DA model. Five potential biomarkers between control group and administration group were identified. The relative content of Alpha-Tocotrienol, PC(14:1(9Z)/14:1(9Z)), Stearic acid, Theasapogenol A, Docosahexaenoic acid increased.
Conclusion: The biomarkers had many beneficial activities, so the Mongolian medicine Polygonatum odoratum had the function of health care.

Objective To investigate the value of 99Tcm-methoxyisobutylisonitrile (MIBI) scintigraphy in assessing the preoperative chemotherapy response and multidrug resistance of osteosarcoma.Methods From January 2007 to October 2008, 12 patients (female:4, male:8; mean age:16.3 years,range:8-27 years) underwent early (10min) and delayed (120 min) 99Tcm-MIBI scintigraphy before and after preoperative chemotherapy.Seven cases had osteosarcoma at the distal femurs, 2 at the proximal tibias, 2 at the upper end of humerus and 1 at the fibula.The tumor-to-background ratio (T/B) and washout rate (WR) were calculated.Tumor necrosis was classified according to Huvos criterion after limb salvage surgery.Immunohistochemical staining for P-glycoprotein(gp) was examined.Spearman correlation analysis and t-test were performed.Results According to Huvos criterion, 7 patients were classified as good responders with more than 90% of tumor cell necrosis and 5 as poor responders with less than 90% of tumor cell necrosis.R value (ratio of early phase T/B after and before chemotherapy) was significantly lower in good responders than that in poor responders (0.473 ± 0.21 vs 0.998 ± 0.06, t= 5.342, P= 0.000 ).R value was significantly correlated with the degree of tumor cell necrosis ( rs=- 0.87, P= 0.000 ).WR was significantly higher in patients with positive P-gp expression than that in patients with negative P-gp expression ((38.36 ±18.64)% vs (6.40±5.87)%, t= -3.278, P=0.008).There was significant correlation between the WR and P-gp expression (rs = 0.91, P= 0.001 ).Conclusion 99Tcm-MIBI scintigraphy is a feasible non-invasive technique to assess the chemotherapy response and to detect P-gp expression of osteosarcoma.

?-arbutin is biosynthesized by whole cell method with Xanthomona maltophilia BT-112.The conditions for cell biosynthesized ?-arbutin are investigated as follows:temperature,25℃;concentration of hydroquinone,30mmol/L;mol ratio of sucrose and hydroquinone,20∶1;time course of ?-arbutin biosynthesis,45 hours;rotational speed,160r/min;concentration of Xanthomona maltophilia BT-112,85g/L;concentration of K-2HPO-4-KH-2PO-4 buffer solution,25mmol/L;pH of K-2HPO-4-KH-2PO-4 buffer solution,8.0.Under the above optimal conditions,the maximum of molar conversion yield based on the amount of hydroquinone supplied reaches 86.7%.
