OBJECTIVETo explore the effect of total flavonoids of Herba Epimedium (FHE) on BMP-2/RunX2/OSX signaling pathway in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs).
METHODSPassage 3 BMSCs were randomly divided into the control group, the experimental group, and the inhibitor group. BMSCs in the control group were cultured in 0.2% dimethyl sulfoxide + Osteogenuxic Supplement (OS) fluid + DMEM/F12 culture media. BMSCs in the experimental group were intervened by 20 microg/mL FHE. BMSCs in the inhibitor group were intervened by 20 microg/mL FHE and 1 microg/mL NOGGIN recombinant protein. At day 9 alkaline phosphatase (ALP) activity was measured. Calcium nodules were stained by alizarin red staining and the density was observed. The transcription expression of osteogenic differentiation-related proteins (type I collagen, osteocalcin, and osteopontin) and related factors of BMP-2/RunX2/OSX signaling pathway was assayed by RT-PCR.
RESULTSCompared with the control group, ALP activities were enhanced and the density of calcium nodules significantly increased; type I collagen, osteocalcin, and osteopontin expression levels were increased in the experimental group. The expression of osteogenesis-related transcription factor was also increased in the experimental group. Noggin recombinant protein inhibited FHE promoting BMSCs osteogenesis in the inhibitor group. Compared with the experimental group, ALP activity decreased (P < 0.05), the density of calcium nodules was lowered, expression levels of type I collagen, osteocalcin, osteopontin significantly decreased (P < 0.05) in the inhibitor group.
CONCLUSION20 microg/mL FHE promoted osteogenic differentiation process of BMSCs by BMP-2/RunX2/OSX signaling pathway.

Objective:To establish the RPB5-mediating protein (RMP)-silenced stable cell lines and study the inhibitory effects of small interfering RNA (siRNA) targeting RMP gene on the proliferation and migration of human hepatoma SMMC-7721 cells. Methods:Three RMPi siRNAs were designed and synthesized in vitro and transfected into SMMC-7721 cells. The inhibitory effect of siRNA on RMP gene expression was measured by RT-PCR to select the best siRNA. The expression vector pGPU6-Neo-RMP-484 was transfected into SMMC-7721 cells by the lipofectamine and the cells stably expressing the siRNA were selected by G418. RT-PCR was used to detect the interference efficacy against RMP gene. Cell proliferation and adhesion were measured by MTT assay. Wound healing test was used to observe the migration ability of cells. Results:The SMMC-7721 cell lines with down-regulated RMP expression were established by using RNA interference technology. Compared with the negative control cells, expression of RMP mRNA was down-regulated by(83.67±2.56)% .The proliferation of stable-transfected cells was inhibited by(74.33±0.58)% . The adhesion capability of stable-transfected cells was enhanced but the migration capacity was decreased compared with the negative control cells. Conclusion:The pGPU6-Neo-RMP-484 cell lines with stable transfection of RMP siRNA recombinant vector are successfully screened,which can be used as a cellular model for studying the molecular mechanism of RMP. Down-regulation of RMP gene expression can effectively inhibit the proliferation, enhance the adhesion, and decrease the migration of SMMC-7721 cells.

Objective To investigate the efficacy and toxicity of neoadjuvant regional arterial chemotherapy in the treatment of advanced gastric cancer. Methods The clinical data of 158 patients with advanced gastric cancer and with the same clinical stages who were admitted to Renji Hospital of Shanghai Jiaotong University from February 2002 to May 2005 were retrospectively analysed. Preoperative regional arterial chemotherapy was applied to 76 patients (test group) and the remaining 82 patients only received surgical treatment (control group). The chemotherapy regimen was epirubicin (50 mg/m2) + cisplatin (60 mg/m2) + 5-fluorouracil (1000 mg/m2).This regimen was modified to oxaliplatin (130 mg/m2) + 5-fluorouracil (1000 mg/m2) since 2003, and surgery was performed 6-11 days after the chemotherapy. All patients received postoperative intravenous chemotherapy.The clinical effects, radical resection rate, operative complications and long-term survival of the two treatment methods were evaluated. All data were analysed using the chi-square test and Kaplan-Meier analysis. Results The radical resection rate was significantly higher at 86% (65/76) in the test group compared with 71% (58/82)in the control group ( x2 = 5.01, P < 0. 05 ). The toxicity of the chemotherapy in the test group was mild. The postoperative complication rate was 20% (15/76) in the test group and 16% (13/82) in the control group, with no significant difference between the two groups (x2 = 0.41, P>0.05). The median survival time was 41 months in the test group and 23 months in the control group. The 5-year overall survival rate was higher in the test group (44.6%) than that in the control group (29.1%) (x2 =3.95, P<0. 05). Conclusions Neoadjuvant regional arterial chemotherapy is well tolerated by patients with advanced gastric cancer. It is also effective for increasing the radical resection rate and improving the long-term survival.
