Objective To study the clinical value of 18F-FDG PET/CT in childhood neuroblastoma (NB). Methods 18F-FDG PET/CT was performed in 31 children diagnosed with NB. According to the treatment conditions, patients were divided into pre-therapy group, radiation and chemotherapy group, postoperative group, respectively. The positive rate, sites, and im-age characteristics of the primary lesion and metastasis lesion were analyzed through qualitative and quantitative analysis of the image. Results Twenty-one (67.7%) and fourteen (45.2%) patients were found positive in primary sites by CT and PET respectively. All cases (9/9, 100%) in pre-therapy group were found positive in primary lesions by PET, 3 positive cases (75.0%) in radiation and chemotherapy group and 2 positive cases (11.1%) in postoperative group. Twenty-one patients showed metas-tases (67.7%). Lymph nodes (16 cases) and bone (bone marrow) (13 cases) were the most common sites of metastasis followed by pleura, meninges, liver and retrobulbar inifltration, all of which showed increased FDG uptake. Two patients were found lesions in lungs by CT, but had no FDG uptake. SUVmax of primary lesions was signiifcantly different among pre-therapy, chemotherapy and postoperative group (H=13.89, P=0.001), and pre-therapy group had the highest value. Metastases (lymph nodes, bone and bone marrow, pleura, liver and meninges) in pre-therapy group had high SUVmax. Conclusions NB primary tumors are characterized by the increased FDG metabolism. PET can fully detect the distribution of NB metastases in whole body. Except the pulmonary metastasis, metastases in other positions show increased FDG uptake. PET has potential role in evaluating the efifcacy of radiation and chemotherapy, and identifying postoperative residual or recurrence.

BACKGROUND: Although single gene can induce bone marrow mesenchymal stem cells (BMSCs) into chondrocyte, it still has limit action, polygene interaction accord with real demand of body internal environment and is helpful to play synergistic effect and to improve the differentiated effect.OBJECTIVE: To investigate the secretion of target gene and differentiation of BMSCs transfected by BOX-9 and insulin-like growth factor-1 (IGF-1) gene alone and together into chondrocytes.DESIGN, TIME AND SETTING: Two-specimen observation was conducted in the Cell Biological Laboratory of China Medical University between April 2008 and February 2009. MATERIALS: Two 6-week-old healthy male Wistar rats were used for the BMSCs extraction. METHODS: The plasmids pcDNA3.1-1GF-1 and pcDNA3.1- BOX-9 were amplified and extracted. BMSCs of Wistar rats were separated and purified. According to the transfect situation, the BMSCs were divided into 5 groups. ①Non-transfected group:serum-free and double-antibody-free L-DMEM; ②empty vector transfection group: serum-free and double-antibody-free L-DMEM + pcDNA3.1 empty vector and liposome; ③BOX-9 transfection group: serum-free and double-antibody-free L-DMEM +pcDNA3.1-SOX-9 plasmid and liposome; ④IGF-1 transfection group: serum-free and double-antibody-free L-DMEM+pcDNA3.1-1GF-1 plasmid and liposome; ⑤SOX-9 and IGF-1 transfection group: serum-free and double-antibody-free L-DMEM+ pcDNA3.1-1GF-1 plasmid and liposome, pcDNA3.1-SOX-9 plasmid and liposome.MAIN OUTCOME MEASURES: After being transfected, the cells were selected, the proliferation activity was tested by MTT and expression levels of target gene and protein were tested by RT-PCR and Western blot. RESULTS: The proliferation activity (A value) of BMSCs transfected by SOX-9 alone, iGF-1 alone, SOX-9 and IGF-1 together was significantly higher than that of BMSCs in the non-transfected group and empty vector trensfection group (P < 0.01). RT-PCR and Western blot result showed that SOX-9 expression was the highest in the group transfected by SOX-9, the expression of IGF-1 was the highest in the group transfected both by SOX-9 and IGF-1, and the expression of collagen Ⅱ was the highest in the group transfected both by SOX-9 and IGF-1.CONCLUSION: The double gene transfection is supedor to single transfection with regard to the differentiation of BMSCs to chondrocytes and the secretion of extracallular matdx. It is indirectly suggested that IGF-1 induces BMSCs to differentiate into chondrocytes, but the capacity is less than SOX-9.

Objective To investigate the effect of arsenic trioxide on human coronary smooth muscle cells(HCSMCs). Method After the subculture of HCASMCs, cells were divided into 4 groups: control group and three arsenic trioxide (4.0 μmol/L) groups as the arsenic agent co-cultured with cells for 12,24 and 48 h. Flow cytometry and TUNEL were used for counting the ntmnber of cell apoptosis. RT-PCR was used to detect the expression of E2F-1 mRNA and Western blot was used to measure the levels of Bcl-2 ond Bax. Results Arsenic trioxide inhibited the proliferation of HCASMCs. When arsenic trioxide was 4.0 μmol/L, the living cells were ( 8.44 ±0.10) × 105/mL,signifiantly than that of control group (16.44 ± 1.34) × 105/mL, P < 0.05. This inhibition of proliferation cycle was produced by affecting S and G2-M phase, which did not appear in the control group. Apoptotic cells increased from 16.0% ± 3.1% to 38.7% ± 2.7% (P < 0.05) detected by TUNEL. The arsenic agnet decreased the Bcl-2 level and increased Bax. The expression of E2F-1 mRNA was decreased in 4.0 μmol/L arsenic trioxide group. Conclusions Arsenic trioxide exerts the apoptotic effect on human coronary smooth muscle cells.

Aims To study the effects of clenbuterol on anoxia/reoxygenation( A/R) injury in neonatal Wistar rat cardiomyocytes and to explore whether its mecha-nism is related to reperfusion injury salvage kinase ( RISK) or not. Methods The cultured primary neo-natal cardiomyocytes were randomly divided into eight groups: ①normal culture group; ②anoxia/reoxygen-ation( A/R) group;③ clenbuterol ( 1 μmol · L-1 ) +A/R;④ICI118,551(10 μmol·L-1) + clenbuterol ( 1 μmol · L-1 ) + A/R; ⑤Metoprolol ( 10μmol · L-1 ) + clenbuterol(1μmol·L-1 ) + A/R group;⑥Metoprolol ( 10 μmol · L-1 ) + A/R group; ⑦PD98059 ( 20 μmol · L-1 ) + clenbuterol ( 1 μmol · L-1 ) + A/R group;⑧ LY294002(10 μmol·L-1 ) +clenbuterol(1 μmol · L-1 ) + A/R group. Cell via-bility was determined by the conventional MTT reduc-tion assay. The content of LDH in cultured medium was measured with colorimetry. Cardiomyocyte apopto-sis was determined by Hoechst33342 . Intracellular re-active species( ROS) were monitored by the fluorescent DCFH-DA. Total ERK2 and phosphorylated ERK were detected by western blot. Results Compared with A/R group, clenbuterol significantly increased vaibility of cells, reduced LDH release, lowered the rate of apop-tosis and ROS production. When addedβ2 receptor an-tagonist ICI118 , 551 , PI3 K inhibitor LY294002 and ERK inhibitor PD98059 , the effects of clenbuterol a-bove were inhibited; but β1 receptor antagonist Meto-prolol protected the cardiomyocytes from A/R injury, as evidenced by decreased LDH release and increased cell viability. There were no synergistic effects in the combined use of clenbuterol and Metoprolol. Conclu-sion clenbuterol exerts cardioprotective effects against A/R injury by inhibiting oxidative stress and apopto-sis. The protection of clenbuterol is inhibited by ICI118 , 551 , LY294002 and PD98059 . clenbuterol protects cardiomyocytes against A/R injury via RISK pathway by activation of β2 receptor.
