OBJECTIVETo evaluate the inhibitory effect of genistin combined with anastrozole on the growth and apoptosis of breast tumor tissue, and to study their anti-cancer mechanism by using the model of 7,12-dimethylbenz [alpha] anthracene (DMBA)-induced mammary tumors following ovariectomy in Sprague-Dawley (SD) rats.

METHODSThe DMBA induced postmenopausal SD rats were randomly divided into the control group, the genistein group, the anastrozole group, and the genistein combined with anastrozole group. The growth of tumors was observed in each group. The proliferation index and apoptosis index of tumor cells were determined. Moreover, estradiol (E2) and 17beta-HSD1 mRNA levels were determined by ELISA and RT-PCR respectively.

RESULTSThe tumor growth was inhibited in the genistein group and the anastrozole group. The inhibitory ratio was significantly higher in the genistein combined with anastrozole group (P < 0.05). Compared with the control group, levels of E2 and 17beta-HSD1 mRNA decreased more significantly in the genistein combined with anastrozole group (P < 0.05).

CONCLUSIONSGenistein could suppress the growth of mammary tumors in postmenopausal rats. It showed synergistic effect when combined with anastrozole, which resulted in reduced levels of E2 and 17beta-HSD1 mRNA. It had inhibitory effect on the growth of breast tumors.

Objective To investigate the roles of sphingosine kinasel (SPK1) in apoptosis,invasiveness and multidrug resistance of human hepatocellular carcinoma cell line BEL-FU.Methods BEL-FU cells were infected with adenovirus carrying SPK1wT gene and SPK1siRNA (Ad-H1-SPK1) gene.Their effects on biological characteristics of BEL-FU cells were evaluated by MTT,cellular SPK enzyme activity assay,Transwell Migration Technology and Western-blot,respectively.Results AdSPK1wT significantly increased SPK activity but SPK1siRNA(Ad-H1-SPK1) decreased SPK activity.Over expression of SPK1 suppressed the apoptosis induced by DMS(Dimethyl sphingosine,DMS) and enhanced migration of BEL-FU cells.The cells infected with SPK1 siRNA( Ad-H1-SPK1)significantly increased the apoptosis induced by DMS and inhibited the migration of human hepatocellular carcinoma cells.The expression of multidrug resistance-related protein (MRP1) of cells infected with SPK1siRNA (Ad-H1-SPK1) was suppressed significantly compared with the control group,while the expression of MRP1 infected with Ad- SPK1wT was enhanced.Conclusion SPK1 activity is closely associated with apoptosis、migration and multidrug resistance of human hepatocellular carcinoma cells,therefore,it may serve as a new target for HCC treatment.

Objective: To investigate the multi-imaging diagnostic values, especially MSCT technology in patients with congenital aortic diverticulum with its clinical application. Methods: The MSCT ifndings in 12 patients with congenital aortic diverticulum were retrospectively analyzed. Results: There were 9 patients with right aortic arch and 1 with left aortic arch, all of them having coexisted aberrant subclavian artery which initially dilated like aneurysm by diverticulum changing (Kommerell diverticulum), and there was 1 patient with incomplete double aortic arch with atresia of left arch combining retro-esophageal aortic diverticulum (RAD) and 1 patient with ducts diverticulum. Echocardiogram only made the suggestive diagnosis of speeding up blood lfow or right aortic arch in 4 patients. While MSCT accurately displayed the diverticulum for the location, morphology and with or without other complications. The post-eroanterior chest radiograph indicated “double aortic node” as the special sign in 8 patients. The echocardiogram, X-ray and MSCT for correctly diagnosing the aortic diverticulum were as 0, 72.7% and 100% respectively. Conclusion: MSCT is a rather ideal non-invasive diagnosing method for aortic diverticulum, meanwhile X-ray could also make suggestive diagnosis; if MSCT and X-ray joint with echocardiogram examination may provide the effective supplement for valve structure and hemodynamics condition in relevant patients.

Objective To analyze the reason of hemoptysis after the bidirectional Glenn shunt procedure on complex congenital heart disease.Methods The feature of imaging data of 24 patients (1 6 males,8 females;age ranges:3-27 years;14 cases of single ventricle,3 cases of tricuspid Atresia,4 cases of pulmonary Atresia,3 cases of double Outlet Right Ventricle)after the bi-directional Glenn shunt procedure were retrospectively studied.Results Six patients had various degrees of hemoptysis (50 - 300 mL)after surgery,except for one case which has bronchiectasis on the left inferior lobe.The common feature of the other 5 cases present as plaque ground glass opacity and pulmonary arteriovenous fistula located at the corresponding subpleural field.After different therapy (three cases were performed endovascular management,2 cases were under expectant treatment),the lesion disappeared or obviously smaller which was clear evidence for the existence and bleeding of fistula.The occurrence of this disease in the present study was nearly 20.8%,which were accord with references.Conclusion Pulmonary arteriovenous fistula should be considered when crypto-genic hemoptysis happened after bi-directional Glenn shunt with complex congenital heart disease which exclude tuberculosis,bron-chiectasis or rupture and bleeding of MAPCAs.Multiple sliced CT angiography can be used to as the first line examination and sup-ply acute evidence for clinic therapy in time.

In order to analyze the immunogenicity of the recombinant EG95s protein ,the recombinant plasmids of pET-1EG95s ,pET-2EG95s and pET-3EG95s which containing respectively 1 ,2 ,and 3 copies EG95s were induced to express HIS-1EG95s ,HIS-2EG95s and HIS-3EG95s ,and then the proteins were purified and identified by western-blotting .The same im-mune process was used ,and 8 weeks-old BALB/c mice were immunized ,then its immunogenicity was analyzed by detecting an-tibody levels in mice by indirect ELISA method .Results showed that for recombinant EG95s proteins after transformation , HIS-1EG95s ,HIS-2EG95s ,and HIS-3EG95s also retained immunogenicity and could induce specific antibodies in mice .One week's late after the first immunization with HIS-1EG95s ,the antibody level of was significantly higher than HIS-2EG95s and HIS-3EG95s .But began from 2 weeks after immunization ,the antibody level of HIS-3EG95s was always higher than that of HIS-1EG95s group during the period of the immune .Both the final antibody titers after immunization of HIS-1EG95s and HIS-2EG95s groups was 1∶819 200 ,while HIS-3EG95s group was 1∶163 840 0 .HIS-1EG95s ,HIS-2EG95s and HIS-3EG95s all induced IFN-γin immune mice ,but the difference was not significant .The HIS-1EG95s showed lower response to Echinococ-cus granulosus positive serum than HIS-2EG95s and HIS-3EG95s .It’s indicated that the HIS-1EG95s and HIS-3EG95s also had good immunogenicity .HIS-3EG95s make recombinant protein immunic effects more lasting ,and benefit to generate more long-lasting protective immunity .This study provides the scientific basis for the immunization of echinococcosis (hydatidosis) .

Objective To compare the clinical value of three visual rating scales (VRS) for white matter lesions (WML) in Alzheimer's disease (AD) and mild cognitive impairment (MCI).Methods Totally 184 subjects (including 107 AD patients,47 MCI patients and 30 normal controls)were recruited.All subjects underwent comprehensive neuropsychological tests and were examined with a standard protocol of MR imaging.WML burden was rated with the Age-Related White Matter Changes (ARWMC) rating scale,Cholinergic Pathways Hyperintensities Scale (CHIPS) and Fazekas scale.Consistence of the three rating scales were analyzed,and detection results of WML in AD/ MCI/NC group with the three rating scales were compared.The relationship between WML and cognitive function in AD and MCI groups were explored.Results ARWMC rating scale,CHIPS and Fazekas scales were moderately to highly correlated with WML (r=0.61-0.78,all P＜0.01).ARWMC showed that WML were in the left and right frontal lobes in AD and MCI groups and in the right frontal lobe and left temporal lobe in NC group,which had significant differences (F=4.20,4.69,4.69,3.36,respectively,all P＜0.05).WML in the left temporal lobe had a significant difference between MCI group and NC group (F=3.36,P＜0.05).CHIPS showed that WML in the front left side of centrum semiovale in AD and MCI groups had significant difference as compared with that in NC group (F=4.88,P＜0.05),and WML in the rear right side of low external capsule had a significant difference between AD and NC groups (F=3.04,P＜0.05).Fazekas scale showed that there was no difference in WML among AD,MCI and NC groups.ARWMC showed that scores of WML in right temporal lobe were positively correlated with concentration and visual construction,and bilateral basal ganglia were negatively correlated with the concentration.Fazekas scale showed that scores of WML in periventricular were negatively correlated with concentration,MMSE and orientation,scores of WML in deep white matter were negatively correlated with concentration,abstraction and judgment,and the whole scores were negatively correlated with concentration.CHIPS showed that the scores of WML in the rear left side of low external capsule were negatively correlated with short-term memory in MCI group.Conclusions The three rating scales well consistent with each other.ARWMC rating scale and CHIPS can detect the differences in WML between AD,MCI and NC groups.The scores of CHIPS in WML are related with cognition in MCI group,while scores of ARWMC and Fazekas scale in WML are correlated with many aspects in cognitive function in AD group.In general speaking,CHIPS in MCI patients and ARWMC rating scale in AD patients show more advantages in the detection of WML and have better correlation with cognitive function.
