Objective To investigate the effects of allogenic intra-bone marrow bone marrow transplantation (IBM-BMT) on re-establishing hematopoiesis in mice. Methods Bone marrow mononuclear cells (BMNCs) from BALB/ c mice were transplanted into the C57BL/6 mice treated with a lethal dose of ~(60)Coγ-ray radiation through intra-bone marrow injection or intravenous injection. Sixty of the C57BL/6 mice were randomly divided into three groups as higher dose intra-bone marrow injection group (IBM1 group), lower dose intra-bone marrow injection group (IBM2 group) and intravenous injection group (IV group). The nucleated cell numbers of whole bone marrow from the tibia of each recipient mouse were counted respectively at the day 1, day 3, day 6 and day 9 after the transplantation. The donor-derived total nucleated cells and myeloid cells were quantified by flow cytometry. Results At 6th day after transplantation, more total bone marrow nucleated cells, total donor-derived nucleated cells and donor-derived myeloid cells in the tibia of injected side in both IBM1 group and IBM2 group were found than that in IV group (P<0.05 or P<0.01). Conclusion Compared with traditional bone marrow transplantation (IV-BMT),IBM-BMT improves the bone marrow hematopoiesis in the early hematopoietic re-establishing stage in allogenic bone marrow transplantation.

To investigate whether human umbilical cord plasma (HUP) can be used to culture human cord blood mesenchymal stem cells (HUCMSCs), we collected 20 surplus HUP. After being treated with salting out and diasysis, the HUP were used to culture HUCMSCs as 10% volume, and compared with fetal bovine serum (FBS). Morphological characteristics, growth curve and reproductive activity of HUCMSCs cells were observed. The concentration of bFGF and noggin secreted by HUCMSCs cultured with HUP and FBS medium were detected by ELISA. It was found that compared to FBS, the morphology, reproductive activity and characteristic of HUCMSCs cell cultured with HUP were not distinctively different from FBS. The concentration of bFGF in HUP group was significantly higher than that of FBS group, and the concentration of noggin was also different in the two groups. So we concluded that HUP could be used to culture HUCMSCs for a long-time, and the HUP mediumcoild could be more suitable for the culture of human embryonic stem cell (hESC).

Objective To observe the influence of recombinant human thyrotropin(rhTSH)on serum concentration of endogenous thyrotropin(TSH), free triiodothyronine(FT3), free thyroxine(FT4), thyroglobulin antibody(TGAb), and thyroglobulin(Tg). To evaluate the efficacy of rhTSH-aided radioiodine treatment in patients with differentiated thyroid carcinoma(DTC). Methods The study recruitment took place between November 2007 and March 2009. 62 patients(including 45 females)with biopsy confirmed DTC had undergone total or nearly total thyroidectomy, and received 131I treatment. 31 patients(including 22 females), median age of 45 years(23-72), received radioiodine treatment 4 weeks after L-thyroxine(T4)withdrawal. The other 31 patients(including 23 females), median age of 44 years(14-70), underwent rhTSH-aided radioiodine treatment. Before and after rhTSH injection, serum TSH, FT3, FT4, TGAb, and thyroglobulin were tested. Post-radiotherapy whole body scan was performed 5 to 7 days after radioiodine treatment and qualitatively and blindly evaluated by two nuclear medicine physicians. Follow-up took place 6 to 12 months after radioiodine treatment. The efficacy of rhTSH-aided radioiodine treatment was evaluated by whole body scan with diagnostic dose radioiodine. SPSS 13.0 statistical software was applied. Results (1)Before and after rhTSH-aided radioiodine treatment, the serum TSH was(1.08±4.01)vs(140.26±27.20)mIU/L(P<0.05), thyroglobulin(23.75±132.92)vs(169.58±178.49)μg/L(P<0.05), FT3(4.52±1.16)vs(4.42±1.11)pmol/L(P>0.05), and FT4(15.09±5.83)vs(13.66±5.85)pmol/L(P>0.05),respectively.(2)rhTSH-aided radioiodine ablation treatment had the same effect as L-T4withdrawal aided. The complete response ratio was 77.4% vs 71.0%(P>0.05)by radioiodine whole body scan of diagnostic dose. Conclusion rhTSH-aided radioiodine treatment of DTC was effective and safe, and did at least at equivalent degree as did L-T4withdrawal. Furthermore, Serum thyroglobulin level could be effectively stimulated by rhTSH with tumor relapse or metastasis.

ObjectiveTo investigate the relationship between Dicer expression and clinicopathological characteristics and prognosis by detecting the expression of Dicer in hilar cholangiocarcinoma tissues and cells.MethodsThe expression of Dicer in tissues was detected using immunohistochemistry.Western blotting and RT-PCR were used to investigate Dicer expression in QBC939 and HIBEpic cells.The relationship between Dicer expression and clinicopathological characteristics was analyzed.A Kaplan-Maier analysis was performed to analyze the disease-free survival (DFS) and overall survival (OS) after radical surgical resection of hilar cholangiocarcinoma.ResultsWhen compared to control,Dicer was significantly down-regulated in hilar cholangiocarcinoma tissues (P<0.05) and in QBC939 (P<0.05).The expression of Dicer was higher in well differentiated adenocarcinoma than poorly and moderately differentiated tumours. Univariate analysis showed low expression of Dicer protein was significantly correlated with short disease-free survival and overall survival of patients with hilar cholangiocarcinoma after radical surgical resection (P<0.01). Multivariate analysis revealed that the expression of Dicer was the most important factor for predicting prognosis after radical surgical resection of hilar cholangiocarcinoma (P<0.05).ConclusionsDicer could be used as a prognostic marker for hilar cholangiocarcinoma.
