The genus Scilla consists of 90 species widely distributed in Europe, Asia and Africa, one and its variant of which can be found in China Some species of the genus have been used in traditional medicine to treat various diseases related to inflammation and pain. Phytochemical studies have demonstrated the presence of triterpene and tritepenoid saponins derived from eucosterol, bufadienolides, alkaloids, stilbenoids and lignan in the plants of this genus. Various bioactivities such as antimicrobial, anti-inflammatory, antioxidant, anti-tumor and glycosidase inhibitory activities, have been reported. In this review, the advance of chemical constituents and pharmacological activities of the Scilla species are summarized for further development and utilization of the resource.

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P<0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P<0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.

Objective To explore the clinical value of virtual touch quantification technique(VTQ)and fibroscan technique for the diagnosis of hepatic fibrosis.Methods A total of 1 02 patients with chronic liver disease and 78 normal individuals were enrolled in the study.They were all examined with VTQ and fibroscan technique.Pathological results were used as standard criterion.Results The liver tissue riqidity was associated with pathological results.The coefficient of relativity was 0.43309(VTQ)and 0.35840(Fibroscan).ROC curve displayed that VTQ value of 1.4 m/s and fibroscan value of 7.75 kPa can be used to differential diagnose the lowgrade liver fibrosis and high-grade liver fibrosis.The probability of success was 100 0A(102/102)and 100%(78/78)by VTQ,but 88%(90/102)and 100%(78/78)by fibroscan technique.Conclusions VTQ and fibroscan technique are useful in the diagnosis of hepatic fibrosis.Compared with fibroscan technique,VTQ has more advantages in sensitivity practicability and convenience.

Objective To explore the clinical value of virtual touch quantification (VTQ) technique in assessing the hepatic fibrosis. Methods A total of 115 inpatients with chronic liver disease receiving liver biopsy were enrolled in this study, all patients liver tissue was checked by VTQ technique, and the results were compared with those of the control group including 80 healthy subjects. Results VTQ value was significantly different between the two groups (P = 0.0000).The VTQ value among different degree of hepatic fibrosis but between S0 and S1 had statistical significances (P = 0.0212, P = 0.0000).ROC curve displayed that VTQ value of 1.4 m/s could be used to diagnose middle-high-grade liver fibrosis, the sensitivity and specificity were 85.4 % and 64.7%, respectively. Conclusions VTQ can be used as a noninvasive and effective means for assessing the degree of hepatic fibrosis.
9.NT-pro-BNP in the evaluation of daunorubicin-indued cardiotoxicity in acute childhood leukemia.
Chinese Journal of Hematology 2010;31(9):621-623
OBJECTIVETo evaluate the sensitivity of NT-pro-BNP in daunorubicin (DNR) induced myocardial damage by monitoring the level of NT-pro-BNP and myocardial enzymes (CK, CKMB) before and after DNR treatment in childhood acute leukemia (AL) and performing control study.
METHODSSixty-two cases (total 194 samples) which diagnosed as primary AL were enrolled and had received the conventional chemotherapy. According to the cumulative dose of DNR, they were divided into three groups: cumulative dose ≤ 60 mg/m(2) (group A); cumulative dose 60 - 120 mg/m(2) (group B); cumulative dose > 120 mg/m(2) (group C) and 15 cases with idarubicin (IDA) or mitoxantrone (MXR) as altervative to DNR (group D).
RESULTSThere was a significant difference (P = 0.000) in the level of NT-pro-BNP before and after DNR therapy, but did not in the myocardial enzymes activities (CK, P = 0.085 and CKMB, P = 0.076). The level of NT-pro-BNP appeared obviously elevated (P = 0.001) when DNR cumulative dose > 60 mg/m(2). While the level of CKMB did (P = 0.022) until DNR cumulative dose > 120 mg/m(2). In the 15 cases used IDA or MXR as alternative to DNR, the level of NT-pro-BNP fall from (239.9 ± 230.0) ng/L to (137.0 ± 131.9) ng/L (P = 0.024).
CONCLUSION(1) Compared with myocardial enzymes detection, NT-pro-BNP level can predict earlier DNR-induced cardiotoxicity. (2) Selection of the second or third generation anthracycline to treat AL can significantly reduce the cardiotoxicity in children.

Objective To investigate the value of whole-liver MR perfusion imaging(MRPI)for early detection of coagulative necrosis after percutaneous ethanol injection(PEI)in rabbit liver VX_2 tumors. Methods VX_2 tumor cell suspension was inoculated into rabbit liver and liver VX_2 tumors[diameter of (2.6?0.6)cm]were induced in 10 male rabbits.MR T_1 WI and T_2 WI were performed to monitor the development of the liver tumor on the 2~(nd)and 3~(rd)week after inoculation.Whole-liver MRPI was performed in the 10 rabbits with liver VX_2 tumors before and 6 days after PEI therapy(1.0 ml ethanol was injected into the most enhanced tumor region under CT guiding).Signal intensity(SI)values of untreated tumor parts and treated areas 6 days after PEI were recorded respectively.The steepest slope(SS)and bolus arrival time (TO)of SI-time curves were measured.The t-Student test was used in statistical analysis of the data.Results There was significant difference in MRPI data between untreated tumor parts[TO:(16.0?1.2)s and SS: 38.9?2.2]and treated areas[TO:(50.8?5.9)s and SS:6.0?1.2]6 days after PEI(t was 15.8 and -39.6 respectively,P
