Several resistant characteristics of Glycyrrhiza uralensis seeds were studied. The results showed that hard seed can resist attack from fungi or bacteria. It can endure high temperature for 4h at 80℃ and 10 min at 100℃, but when at 100℃ for 1 h it loses its germinating power. The seeds stored for 4 years do not reduce viability. After long period storage for 13 years,about 60% of the seed still retains its germinating power.

The etiology and pathogenesis of intrahepatic cholestasis are complex,and those are not still very clear in current.Studies suggest that genetic factors play an important role in the pathogenesis of the disease.Some familial cholestasis have been confirmed by gene mutation causing.Bile secretion process regulated by a number of bile relation gene at the molecular level.Farnesoid X receptor (FXR) gene is related to intrahepatic bile secretion process.Bile secretion is indirect control by FXR which formats a complex network,becoming more attention to researcher in recent years.

Objective To assess examinational methods of Multi-slice CT(MSCT)in diagnosis of palatine lesions. Methods 28 cases were performed MSCT examination with the conventional method,extending -tongue method,colliding-tongue method and pronouncing method. All images were reconstructed by means of multiplana reconstruction (MPR) and CT virtual endoscope (CTVE). Results Correct diagnosis were obtained through the complementarity of the methods. Conclusion Reasonable examination methods of MSCT is apt to display palatine lesions.

Objective To explore the diagnosis and surgical treatment of primary intestinal tumors, and improve the level of treatment. Methods Retrospective analysis of the clinical was made on the 68 cases of primary small intestinal tumors confirmed by pathological examination in our department in recent 20 years. HZ Results 34.8%(21/68) was benign tumors in 68 cases, and 69.1%(47/68) was malignancies. The common clinical prevsentations were abdominal pain (69.1%,47/68). gastrointestinal he morrhage (41.1%,28/68) and abdomen mass (13.2%,9/68). The preoperative misdiagnosis rate was 70.5%(48/68) .All the 68 cases performed operation, and no death. The 1 ,2 and 5 years survival rates of malignant tumors were 65.8%,42.1% and 29.3% respectively. Conclusions The clinical presertation of primary small intestinal tumor is non-spectific and the misdiagnosis rate is high. Kinds of diagnosis examinations should be done for the cases whose diagnosis are uncertain, and laboratory examinations should be considered if it is need. The main choice of treatment is surgery and the chemotherapy is necessary for malignant tumors also.

Objective The aim of this study was to measure quantitatively the TSP-4 mRNA expression and its significance in gastric carcinoma was evaluated by correlating its expression with clinicopathological features, microvessel density(MVD) and MMP-9.Methods Eighty-two patients with gastric carcinoma were recruited in this study. TSP-4 mRNA expression in gastric carcinoma and adjacent tissue was detected by real-time PCR. CD34 and MMP-9 protein expression were examined by immunohistochemistry. MVD was determined according to CD34-positive tubular structures. Results The expression level of TSP-4mRNA in gastric carcinoma was obviously higher than those of adjacent tissue(P=0.03) and it was associated with tumor size, histological type, lymph node metastasis, MVD and MMP-9(P=0.002, P=0.031, P=0.014,r＝0.67 P<0.01, P=0.008),but not sex, age and depth of invasion. (P=0.53,P=0.57,P=0.15).Conclusion TSP-4 may play an important role in occurrence and progression of gastric carcinoma and that the effect of TSP-4 on tumor growth and metastasis may be exerted through regulation of angiogenesis and MMP-9 expression in gastric carcinoma.

Objective To evaluate the soft tissue profile in adults with unoperated isolated cleft palate. Methods Twenty patients older than 16 years(median age,18.4) with unoperated isolated cleft palate were enrolled.Soft tissue lateral cephalograms were traced and compared with those of cleft operated patients and class-Ⅰocclusion individuals.The results of various measurements were analyzed with ANOVA by SPSS11.5. Results In adults with unoperated isolated cleft palate,there was restriction at the top of the upper lip,and the antelabrum of upper lip and the lower lip were found normal. Conclusion The soft tissue profile in adults with unoperated isolated cleft palate exhibits almost the same characteristics as the corresponding hard tissue,and there is covering over effect of the soft tissue to some extent.

Objective To investigate the clinical efficacy of Shenqi Fuzheng injection and chemotherapy in elderly patients with non-small cell lung cancer(NSCLC),and to observe its effect on immune function and serum tumor markers of carcino embryonie antigen(CEA),carbohydrate antigen 19-9(CA19-9),cytokeratin 19 fragment(CYFRA21-1)and neuronspecific enolase(NSE).Methods 80 patients with NSCLC who were confirmed as non-small cell lung cancer were enrolled in the study.Among them,the control group received paclitaxel + carboplatin chemotherapy,40 patients; the treatment group received Shenqi Fuzheng injection on the basis of the control group,40 cases.The clinical curative effect was evaluated after four cycles of treatment and the adverse reactions were recorded.The scores of traditional Chinese medicine(TCM)syndrome before and after four cycles of treatment were evaluated,and the quality of life of the patients before and after treatment were evaluated by Karnofsky performance score(KPS).The immune function and tumor markers were measured before and after treatment.Results The total effective rate of the treatment group was 65.0％,which was significantly higher than that of the control group(42.5％,χ2=4.07,P=0.04).In the treatment group,the adverse reaction rate was 37.5％,significantly lower than 62.5％in the control group(χ2=5.00,P=0.02).The score of TCM syndrome in the two groups was significantly lower than that in the control group before treatment,and the KPS score was significantly higher than that in the control group before treatment,the score of TCM syndrome in the treatment group was significantly lower than that in the control group(P<0.05).After treatment,the immune function of patients in the treatment group compared with before treatment had no significant difference,while the control group after treatment of the immune function was significantly lower than before treatment,and compared with the treatment group(P<0.05).The two groups of patients after treatment of tumor markers decreased significantly,and the treatment group decreased significantly compared with the control group(P<0.05).Conclusion Supplemented with Shenqi Fuzheng injection in the treatment of elderly non-small cell lung cancer on the immune function of little effect,help to promote serum levels of serum tumor markers and clinical symptoms improved,reduce adverse reactions,improve clinical efficacy and quality of life.

Aim To evaluate the effects of fibrinolytic enzyme FⅡ from agkistrodon acutus venom on an experimental model of kidney thrombus induced by lipopolysaccharide(LPS). Methods The model of microvascular thrombosis in the rabbits kidney was performed by the method of Hermida, which was induced by infusing LPS. Treatments were begun simultaneously with LPS infusion, through the contralateral marginal ear vein. Six different groups were established: NS 10 ml?h~-1 was infused as the negative control group, urokinase ~20 000 IU?kg~-1 ?h~-1 as positive control group, FⅡwas infused with the dosage of 0.1(Low-dose), 0.3 (medium-dose),0.6 (high-dose) mg?kg~-1 ?h~-1 . The further rabbits, which were given neither LPS nor FⅡ, were infused with saline solution through both marginal ear veins. Kinney sections were examined for the presence of fibrin microthrombi. The measurement of FDP concentrations was used to assess the degradation of microvascular thrombosis. Results Intense fibrin deposition was also detected and FDP concentrations were (78.21?4.79)% and (84.27?6.21)% at 2 and 6 hours after LPS administration in LPS-control group. Little fibrin deposition was detected and FDP concentration also increased in urokinase control group. A lot of fibrin deposition was detected in Low-dose FⅡ group,little fibrin deposition was detected in medium-dose FⅡ group, and no fibrin deposition was detected in high-dose FⅡ group. Additional all doses of FⅡ led to a significant increase in FDP concentration as compared with LPS-control group (P
