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.

The contents of gallic acid, catechin, albiflorin, paeoniflorin, benzoic acid and paeonol extracted in different growth years, collecting season and of different parts of Paeonia lactiflora were determined. The results showed that the contents of catechin and paeoniflorin in Paeonia lactiflora collected in autumn are the highest, and the contents of benzoic acid was lower than that of those collected at other time. The longer is the age of Paeonia lactiflora, the higher is the contents of catechin and paeoniflorin. The contents of catechin and paeoniflorin in the root of Paeonia lactiflora were higher than those in other parts of the plant. There is a certain content of paeoniflorin in the leaves of Paeonia lactiflora. Judging from the result, paeoniflorin is synthesized in the leaf and then transported to the root. Catechin is not synthesized in the leaf, but mainly in the root. Paeonia lactiflora should be collected in autumn, and immature plant should not be collected.

Objective To discuss the diagnosis,differential diagnosis and treatment of obstructive jaundice in infants.Methods Infants with obstructive jaundice were examined by ECT to obtain dynamic images of the liver,biliary tract and intestine to find out the position and nature of the obstruction.Results Eight patients with delayed nuclide imagining were diagnosed as obstructive jaundice of cholestasis.Five of which with aggravated jaundice were cured by biliary irrigation and 3 by medication.For 16 patients with congenital biliary atresia,10 were exterior hepatic types and 6 interior hepatic types.They had the nuclide image of liver and biliary tract.Ten cases of the exterior hepatic types and four cases of the interior types received the Kasai operation.And bile was drained after the surgery.Seven patients survived and 4 of interior heaptic types died postoperatively.Due to bile fistula,3 patients died after the hepato-porto-jejunostomy for internal drainage.Two patients of interior hepatic types who had no operation died of the hepatic failure.Conclusion The nature and position of obstructive jaundice could be identified by nuclide imaging.Young patients with jaundice of cholestasis could be treated by antiinflamation,liver function protection,Hymecromone and Dexamethasone for two weeks.Once the serum bilirubin rises,operation would be indicated.In the case of congenital biliary atresia,operation should be done earlier on the basis of medication.

Objective To develop a HPLC quantitatively test method of glycyrrhizin, liquiritin and isoliquritigenin simultaneously for licorice. Methods The 67% methanol extracts of licorice powder were analyzed by reverse-phase HPLC on an ODS column, using a gradient elution with a mixture of 1% H3PO4 and acetonitrile. The eluate was monitored by UV absorption at 248, 276, 360 and 370 nm. Results The linear equation of glycyrrhizin was Y =1?106X +16 220, r 2=1. The linear equation of liquiritin was Y= 2?106X+49 444, r 2=0.999 5. The linear equation of isoliquritigenin was Y =1?107X +4.466 7, r 2=1. The recovery rate of glycyrrhizin, liquiritin and isoliquritigenin was 98.01%, 102.63% and 98.18% respectively. Conclusion The method is accurate, stable amd reliable, and can be used to determine the three main chemical contents simultaneously.

Object To study the influence of drought stress on imbibition germination of Glycyrrhiza uralensis seed and the drought resistance of its seedling. Methods To measure the imbibition rate, germination rate, seedling growth, relative tissue moisture content, relative electrical conductivity, SOD enzyme activity under drought stress simulated by PEG-6000. Results The imbibition rate, germination rate, SOD enzyme activity, and seedling growth present rising tendency then following by the decrease, while the relative tissue moisture content and the relative electrical conductivity tend to decrease. Conclusion The appropriate drought stress increases both the G. uralensis seed germination rate and the seedling drought resistance.

Objective To establish an HPLC method for the determination of seven flavonoids from the aerial part of Artemisia frigida.Methods Hypersil ODS-2 (300 mm× 4.6 mm,5 μm) column was used,with acetonitril-0.2％ phosphoric acid (gradient elution) as a mobile phase,and the detection wavelength was at 283 nm with flow rate at 1mL/min.Results All calibration curves showed good linear regression (r ＞ 0.9990) within the tested range.All average recovery was more than 98.00％ and RSD was less than 3.0％ (n =6).Conclusion The method is steady and with good repeatability,and could be used to determine the content of flavonoids in A.frigida from different areas.
