AIM: To explore the effect of luteolin on the metastasis of ovarian carcinoma HO-8910PM cells in vitro, and to elucidate its mechanisms. METHODS: The in vitro invasion and mobility of HO-8910PM were measured by Boyden chamber assay after exposure to luteolin for 6 h. Gelatinase activity was tested by gelatin zymography assay. The expression of tissue inhibitor of metalloproteinase-1 (TIMP-1), nm23 mRNA and that of ERK2 protein were tested by RT-PCR and Western blotting, respectively. RESULTS: Luteolin significantly inhibited in vitro invasiveness and mobility in HO-8910PM cells in a dose dependent manner as measured by Boyden chamber assay. Luteolin inhibited the MMP-9 secretion from HO-8910PM cells. Luteolin did not affect the mRNA expression of TIMP-1 and nm23. Luteolin also decreased ERK2 expression. CONCLUSION: Luteolin dose-dependently inhibited the metastasis of HO-8910PM cells in vitro. Inhibition of MMP-9 secretion and ERK2 expression may be involved in the anti-metastasic process of luteolin.

Objective To explore the clinical effects of correction the midface depression.Methods From Aug.2010 to Aug.2015,185 cases of midface depression (aged from 18 to 61 years)were corrected by using structural fat grafting technique,the site and volume were placed as follows,tear trough 1ml,lid cheek groove 2 ml,midcheek groove 0.5 ml,anteriorcheek 4-8 ml,nasolabial fold 1-2 ml,nasal alar base 1-2 ml,evator labii superioris 1-2 ml,zygomaticus major 1-2 ml,buccinator 1-3 ml,and upper lip 3-5 ml.Results 185 cases were followed from 3 months to 3 years and the results were evaluated by visual analogue scales;156 cases of midface depression were corrected after the first structural fat grafting,the midface changed from concave to convex,and acquired prominent malar became more attractive;satisfaction of visual analogue scales were more than 80 ％;only 12 cases needed a second grafting.Conclusions The midface concavity can be corrected effectively by using structural fat grafting technique,the results are satisfied and the technique is safe,simple and effective.

Objective To investigate the anticoagultive effectiveness and specialty of sodium citrate comparing with hep- arin in continuous venovenous hemodiafiltration (CVVHDF).Methods 50 multiple organ disorder patients undergoing CWHDF were randomly divided into two groups:group A(sodium citrate)27 cases,group B(heparin)23 cases,blood e- lectrolyte,acid-alkali degree,cruor index changes,the blood coagulation of tube path way and blood filter were recor- ded.As the same time,side effects were observed in theraphy.Results The patients of two groups were kept stable vital signs,serum electrolyte and blood gas markers during the therapeutic periods.Moreover,ideal serum creatinine and urea clearance rate and uhrafiltration rate were obtained in all patients.The coagulation and longevity of blood filter of Group A are better than Group B,Group A without sigaificantly prolonged cruor index inside body,the dosage of calcium gluco- nate in Group A are greater than Group B.Conclusion Out body anticongulation of sodium citrate is more effective and reliable than regular heparin anticoagulation.

Orally disintegrating tablets (ODT), a kind of new solid tablet that rapidly disintegrates to work in the mouth, has became the hot form of new drug research in recent years with many advantages, such as the convenient taking, a widely applicable people, fast acting, high bioavailability, good compliance, and so on. ODT has been widely used in chemical medicines, while the application of it in traditional Chinese medicines (TCMs) is still in the stage of development The development of TCMs ODT provides a new direction for the research of Chinese medicine new dosage, accelerates the pace of connecting to the world and modernization of Chinese medicine. This dosage has a broad market prospect, and its quality control and assessment standards, taste, the disintegration time in vitro and evaluation method are the key factors that affect the industrialization, standardization of Chinese medicine ODT. Therefore, this paper reviewed the characteristics, preparation, taste masking technology and quality evaluation with new technology of ODT. Meantime, numerous application examples of ODT used in traditional Chinese medicine were described. We expect to provide the reference and utilization for the development of traditional Chinese medicine orally disinteeratine tablets.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

Objective To analyze the clinical features of infantile cytomegalovirus(CMV) hepatitis with cholestasis and investigate intrahepatic cholestasis due to hepatocytic impairment caused by CMV infection.Methods Forty-seven children with CMV cholestatic he-patitis were divided into 2 groups according to the level of total bilirubin(TB):22 cases with serum TB lower than 136.8 ?mol/L(groupⅠ),and 25 cases with serum TB higher than 136.8 ?mol/L(groupⅡ).All children were treated with both gangciclovir and routine met-hods,and serum biochemistry were checked before and after treatment.SPSS 13.0 software was used to analyze the data.Results Forty-seven cases of infantile CMV cholestatic hepatitis had different degrees of jaundice,hepatosplenomegaly and abnormal liver functions.The differences of serum ALT and AST between the 2 groups had statistical significance,the levels of serum gamma glutamy transferase(GGT) and alkaline phosphatase(ALP) were lightly higher in groupⅡcompared with those in groupⅠ,but there were no statistical significance.TB,direct bilirubin(DB),ALT and AST were decreased in the 2 groups after treatment,GGT and ALP hadn′t decreased significantly after treatment.Conclusions CMV infection can injure hepatocytes and epithelials on each grade of bile duct,thus CMV hepatitis causes intrahepatic cholestasis.Cholestasis due to hepatocytic impairment deserves emphasis and intervention should be done as early as possible.Gangciclovir therapy for CMV infection manifest effective and safe in short-term.

The study on the pharmacokinetics of traditional Chinese medicines (TCMs) is a linking science during the modernization of TCMs, and plays an important role in the studies on the complex material base of TCMs, the in vivo process of ingredient/ component and the pharmacokinetics-pharmacodynamics correlation. However, because of the multi-ingredient/component system of TCMs, how to scientifically reveal the pharmacokinetics that is consistent with TCMs' characteristics has long been a hotspot and difficulty for the exploration. The optimal composition structure of the material basis of TCMs shows the best efficacy, while the difference between the multi-ingredient/component composition structures in the efficacy is closely related to their absorption, transport, metabolism and excretion in vivo. In this article, the authors systematically review the study methods for pharmacokinetics of TCMs and their compounds, and explore the pharmacokinetics of TCMs based on the "component structure theory". As a result, the method for integrating TCM component structure and the TCM pharmacokinetics was proposed to be adopted to intensively study the effect of the component structure on the in vivo TCM multi-ingredient/component pharmacokinetic characteristics, in order to promote the TCM modernization and innovation in China.
