Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

Purpose To compare and investigate the oncogenic and metastatic phenotypes in nude mice by injection of rat hepatocellu-lar carcinoma ( HCC) cells L2 via two different routes. Methods Twenty of 7-week-old female BALB/cA mice were randomly divided into 2 groups. After the injections of L2 from liver or spleen lobe, the survival rate, tumor formation rate, carcinogenic features, and metastasis were comparatively studied. Results All of the liver orthotopic nude mice developed liver cancer (100%) with 60% lung metastasis rate, and exhibited an expansive growing pattern with surrounding invasion. In the spleen orthotopic model, 78% mice de-veloped HCC in spleen, with 67% liver metastatic rate and 11% lung metastatic rate, lower than the liver orthotopic model ( P <0. 05). But the microscopically hilar lymph node metastasis rate was 33%. Conclusion The direct liver injection of L2 in female nude mice is a better modeling method for studying the mechanism of both carcinogenesis and metastasis, as well as the evaluation of therapeutic effect of liver cancer.

Objective To explore the relationship between fetal heart size and gestational weeks (GW). Methods The size of left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), aorta (AO), pulmonary artery (PA), foramen ovale (FO), heart area (HA), thoracic area (TA), heart circumference (HC) and thoracic circumference (TC) were measured for 512 fetal hearts at 14-39 GW. The relationship between GW and the measurement was evaluated. Results The size of fetal heart chambers, AO, PA and ventricular septum (IVS) increased with the development of GW. The PA/AO, LA/RA, LV/RV, HC/TC and HA/TA were stable compared with different GW. Conclusion Fetal heart chambers increase with the development of GW. HA is correlated well with GW.

In the present study, a risperidone loaded microsphere/sucrose acetate isobutyrate (SAIB) in situ forming complex depot was designed to reduce the burst release of SAIB in situ forming depot and to continuously release risperidone for a long-term period without lagime. The model drug risperidone (Ris) was first encapsulated into microspheres and then the Ris-microspheres were embedded into SAIB depot to reduce the amount of dissolved drug in the depot. The effects of different types of microsphere matrix, including chitosan and poly(lactide-coglycolide) (PLGA), matrix/Ris ratios in microspheres and morphology of microspheres on the drug release behavior of complex depot were investigated. In comparison with the Ris-loaded SAIB depot (Ris-SAIB), the complex depot containing chitosan microspheres (in which chitosan/Ris = 1 : 1, w/w) (Ris-Cm-SAIB) decreased the burst release from 12.16% to 5.80%. However, increased drug release rate after 4 days was observed in Ris-Cm-SAIB, which was caused by the high penetration of the medium to Ris-Cm-SAIB due to the hydrophilie of chitosan. By encapsulation of risperidone in PLGA microspheres, most drugs can be prevented from dissolving in the depot and meanwhile the hydrophobic PLGA can reduce the media penetration effect on the depot. The complex depot containing PLGA microspheres (in which PLGA/ drug=4 : 2, w/w) (Ris-Pm-SAIB) showed a significant effectiveness on reducing the burst release both in vitro and in vivo whereby only 0.64% drug was released on the first day in vitro and a low AUC0-4d value [(105.2± 24.4) ng.mL-1.d] was detected over the first 4 days in vivo. In addition, drug release from Ris-Pm-SAIB can be modified by varying the morphology of microspheres. The porous PLGA microspheres could be prepared by adding medium chain triglyceride (MCT) in the organic phase which served as pore agents during the preparation of PLGA microspheres. The complex depot containing porous PLGA microspheres (which were prepared by co-encapsulation of 20% MCT) (Ris-PPm-SAIB) exhibited a slightly increased AUC0-4d of (194.6±15.8) ng.mL-1d and high plasma concentration levels from 4 to 78 days [Cs(4-78d)=(7.8±1.2) ng.mL-1]. The plasma concentration on 78 day C78d was (9.0 2.5) ng.mL-1 which was higher than that of Ris-Pm-SAIB [C78d= (1.6 ± 0.6) ng.mL-1]. In comparison with Ris-Pm-SAIB, the AUC4-78d of Ris-PPm-SAIB increased from (379.0±114.3) ng.mL-1.d to (465.0 ±149.2) ng.mL-1.d, indicating sufficient drug release from the Ris-PPm-SAIB. These results demonstrate that the risperidone loaded porous PLGA microsphere/SAIB in situ forming complex depot could not only efficiently reduce the burst release of SAIB depot both in vitro and in vivo, but also release the drug sufficiently in vivo, and be capable to continuously release the drug for 78 days.
