BACKGROUND: Human granulocyte-macrophage colony stimulating factor (hGM-CSF) is a kind of cytokine which can stimulate the differentiation and proliferation of haematopoictic precursor cells and plays an important role in the process of immunoloregulation. Escherichia coli (E.coli) expression system has advantages,such as low cost and high output, over other systems.Therefore, E.coli is still the most commonly used exogenous gene expression system.OBJECTIVE: To observe the expression of hGM-CSF in the E.coli swain DH5α.DESIGN, TIME AND SETTING: The present observational experiment was performed at the Central Laboratory of Biotechnology Research,China Three Gorges University between February and June 2007. MATERIALS: Plasmid pBR322hGM-CSF was purchased from American Type Culture Collection, USA.hGM-CSF antibody was sourced from Sigma Company, USA.IPTG, X-gal,and vector pMGT-18 were purchased from Shanghai Bioengineering Technology Company, China. METHODS: Primer was designed according to hGM-CSF gene. Taking cloning vector plasmid pBR322-hGM-CSF as template, hGM-CSF gene was acquired and recombined into prokaryotic expression vector pGEX-4T-1. Recombinant plasmid confirmed by enzyme digestion and sequencing was transformed into E.coli strain DH5α and induced by isopropy-β-D-thiogalactoside (IPTG). Expression product was identified by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and detected by Western blotting assay. MAIN OUTCOME MEASURES: hGM-CSF expression in the E.coli strain DH5α. RESULTS: SDS-PAGE results revealed that the recombinant hGM-CSF protein with relative molecular weight of 40 500 was produced up to approximately 17.9% of total protein. Western blotting detection results indicated that there was a 40 500 bp brand. CONCLUSION: The present study reconstructed prokaryotic expression vector pGEX-hGM-CSF, induced its expression in the E.coli strain DH5α, and obtained hGM-CSF fusion protein.

This study was aimed to investigate the preventing efficacy of the combined using of Er-Shi-Wu-Wei Shan-Hu (ESWWSH) pill, Ru-Yi Zhen-Bao (RYZB) pill, Er-Shi-Wei Chen-Xiang (ESWCX) pill on the focal cere-bral ischemia injury in rats. A total of 80 Sprague-Dawley (SD) rats were randomly divided into four groups. In the sham operation group and the MCAO model group, normal saline was given orally every day (1 mL/100 g). In the positive control group, nimodipine was given orally every day (1.89 mg/100 g). In the drug combination group, ESWWSH pill (7 mg/100 g), RYZB pill (31.5 mg/100 g), ESWCX pill (49 mg/100 g), were separately given in the morning, noon and evening every day. Improved MCAO was used in the model establishment after 7-day intragastri-cal administration. After 24 h brain infarction, TTC method was used in the determination of the cerebral infarct size. Drying and weighing method was used in the calculation of brain water content. Determinations were made on con-tent of NO in ischemic brain issues (nitrate reductase method); activities of SOD in serum (xanthine oxidase method);content of MDA in serum (TBA method); and activities of LDH in serum (pyruvate method). The results showed that compared with the MCAO model group, the combined using of three Tibetan classical prescriptions can obviously re-duce the cerebral infarct size, brain water content and the NO content in brain issues, increase the activity of SOD, reduce the content of MDA, and reduce the activity of LDH in serum. It was concluded that the research preliminari-ly showed that the combined using of ESWWSH pill, RYZB pill and ESWCX pill can protect the ischemic brain tis-sues, such as reducing the cerebral infarct size, alleviating brain edema, and inhibiting oxidative stress reactions.

Objective:To explore the protective effect of emodin on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced acute liver injury and its mechanism.Methods:A total of 40 male BALB/c mice were randomly (random number) divided into 5 groups ( n=8 in each group): the control group, the emodin group, the D-GalN/LPS group, the emodin+D-GalN/LPS group and the 3-MA+emodin+D-GalN/LPS group. D-GalN (700 mg/kg) and LPS (10 μg/kg) were intraperitoneally injected to induce acute liver injury in mice. Autophagy inhibitor 3-MA (15 mg/kg) and/or emodin (20 mg/kg) were intraperitoneally injected 30 min before the liver injury model. The animals were sacrificed under anaesthesia 6 h after D-GalN/LPS challenge, blood samples and liver tissues were collected. The levels of alanineaminotransferase (ALT) and aspartateaminotransferase (AST) in serum, and myeloperoxidase (MPO) activity of liver tissues were determined by colorimetric quantitative method; the levels of tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by ELISA; the expression of LC3-II and Beclin 1 in the liver tissues were evaluated by Western blot; the pathological changes of liver was evaluated by HE staining. Animal survival rate was also analyzed. The one-way ANOVA was use to compare quantitative data, SNK- q test was used for pairwise comparison between two groups, and Games-Howell test was used when homogeneity of variance were not met. Results:Compared with the control group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(2 476.80 ± 263.14) U/L, (271.71 ± 47.15) U/L, (537.92 ± 89.35) pg/mL, (169.74 ± 25.52) pg/mL, and (1.37 ± 0.22) U/mg] were obviously increased in the D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(1 248.01 ± 380.70) U/L, (142.59 ± 34.63) U/L, (288.91 ± 67.21) pg/mL, (61.83 ± 13.64) pg/mL, and (0.80 ± 0.21) U/mg] were obviously decreased in the emodin+ D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the histopathological abnormalities in liver tissue were significantly alleviated and the survival rate of mice was improved in the emodin+ D-GalN/LPS group. Compared with the control group, the expression of LC3-II and Beclin1 was decreased in the liver tissue in the D-GalN/LPS group, while compared with the D-GalN/LPS group, the expression of LC3-II and Beclin1 was increased in the emodin+ D-GalN/LPS group. With co-administration of 3-MA, the protective effects of emodin in acute liver injury were reversed, the levels of AST, ALT, TNF-α, IL-6, and MPO [(2 398.78 ± 233.57) U/L, (242.79 ± 43.46) U/L, (505.07 ± 67.89) pg/mL, (151.46 ± 14.11) pg/mL, and (1.27 ± 0.15) U/mg] were increased, and the pathological damage of liver tissue was aggravated. Conclusions:Emodin alleviates D-GalN/LPS-induced acute liver injury in mice, which may be related to the activation of protein LC3-II, Beclin1 and restored autophagy.

Objective To discuss the application value of DWI and ADC on predicting therapeutic effect of radiotherapy treatment in NPC. Methods Twenty four local recurrent cases and 38 non-recurrent cases after radiotherapy treatment in NPC were reviewed. MRI and DWI-MRI were performed at pre-radiotherapy and 3, 6, 12 months after treatment, the ADC values of the lesions were analyzed by SPSS 18.0 statistical software. ROC curves based on the ADC values were measured in 3, 6, 12 months after treatment plotted to analyze the threshold ADC value for confirming recurrence. Results The recurrent group and newly diagnosed group showed significantly high signal on DWI, while the non-recurrent group acquired low or mixed signal. The ADC values of the primary tumor in the recurrent group and the non-recurrent group were (0.709 ± 0.078) × 10-3 and (0.693 ± 0.089) × 10-3mm2/s, respectively, t=-0.717,P>0.05, respectively.The ADC values of the primary and recurrent tumor in the recurrent group were (0.730± 0.068) × 10-3mm2/s and (0.709 ± 0.078) × 10-3mm2/s, t=-1.000,P>0.05 , respectively.There were statistical differences between the recurrent group and the non-recurrent group for ADC in 3, 6, 12 months after treatment:(1.128 ± 0.179) × 10-3 and (1.358 ± 0.145) × 10-3mm2/s, t=5.567,P<0.01;(1.164 ± 0.174) and (1.450 ± 0.102) × 10-3mm2/s, t=7.310,P<0.01;(1.107 ± 0.180) × 10-3 and (1.584 ± 0.125) × 10-3mm2/s, t=11.189,P<0.01;respectively. Take 1.29 × 10-3 mm2/s,1.32 × 10-3mm2/s,1.37 × 10-3mm2/s respectively in 3, 6, 12months after treatment as the diagnostic threshold to predict tumor recurrence. The sensitive , specificity, and accuracy were (83.3%, 73.7%, 77.4%), (83.3%, 89.5%, 87.1%), (100.0%, 94.7%, 96.3%).Conclusions Both DWI and ADC value are important for diagnosing and predicting recurrent NPC after radiotherapy treatment, DWI and ADC can be used to regular follow-up after radiotherapy, to further improve the rate of early diagnosis of recurrent NPC.

Objective To select the aptamer to an extracellular soluble fragment of recombinant human TGF-? receptor Ⅱ (TGF-? RⅡ) in order to antagonize TGF-? effectively by using systematic evolution of ligants by exponential enrichment (SELEX). Methods Initial random RNA library was transcripted in vitro from ssDNA 5′-TAATACGACTCACTATAGGGAGGACGATGCGG-N60-CAGACGACTCCCCGA-3′; rhTGF-? RⅡ was used as target protein. Totally,selection of 8 times was carried out in SELEX experiment. Membrane binding assay was performed to detect the evolution of enriched RNA library; Electrophoretic mobility shift assay (EMSA) was done to determine the affinity between the selected nucleic acid sequence and TGF-? RⅡ. Results Evolution of the enriched RNA library along the increased affinity to TGF-? RⅡ was observed with the development of selection. Two types of dominant sequences were isolated and named as sequence A and sequence B. In membrane binding assay,both sequences A and B showed obvious affinity to TGF-? RⅡ. However,no retarded bands were seen in EMSA. Conclusion The affinity of sequences A and B to TGF-? RⅡ is beyond satisfaction. However,possible sequences with improved affinity to TGF-? RⅡ can be selected by post-SELEX on the basis of candidate sequences A and B.
