Objective To analyze the effect on prostate cancer bone metastasis of Uygur and Han people treated with strontium-89-chlovide.Methods The curative effects in 36 cases of Uygur and 40 cases of Han patients with prostate cancer bone metastasis were investigated after intravenous injection with strontium-89-chloride,including palliation of pain,change of metastatic focus,level of prostate-specific antigen (PSA) and interleukin-6 (IL-6).Results After treated with strontium-89-chlovide,compared with the han patients with prostate cancer bone metastasis,the palliation rate (83.33 ％) F-PSA [(29.29 ± 8.69) μg/L] and T-PSA [(3.73 ± 1.48) ml/L] were higher,the bone metastases and the level of IL-6 were more significantly reduced of Uygur patients,and there were statistically significant (x2 =4.113,t =1.359,t =1.849,all P ＜ 0.05).Conclusion It is more effective treated with 89 SrCl-chloride for the Uygur patients with prostate cancer bone metastasis metastases than the Han patients.

Objective To investigate the correlation between the expression of vascular endothelial growth factor-C(VEGF-C) and lymph node metastasis in gastric cancer. Methods The expression of VEGF-C was detected in 30 pairs of fresh primary gastric cancers and their adjacent normal tissues from the same patients by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. Automated image analyzer was used to quantify VEGF-C expression, which was reflected by positive index (PI). Results VEGF-C was highly expressed in gastric cancer cells,whilst its expression was undetectable in adjacent normal tissues. VEGF-C expression was higher in lymph node metastasis group(PI=1.345?0.079) and lymphatic invasive(PI=1.315?0.037) group than that in no-metastasis group(PI=1.156?0.045) and no-invasive group (PI=1.154?0.043)(P

Objective To study the effect of lgG Fc gene on JEV DNA vaccine immunity. Methods Gene encoding IgG Fc was amplified by nested-RT-PCR technique from BALB/c murine spleen cells. JEV prME protein gene was obtained with restriction endonuclease BamH Ⅰ/EcoR Ⅰ from the eukaryotic recombinant named after pJME, which was constructed by us before. Recombinant, named after pJME/IgG Fc, with above two genes encoding JEV prME protein and BALB/c murine IgG Fc was constructed, and was tested by restriction enzymes analysis and DNA sequencing, then was transfected into China hamster ovary (CHO) cells by Lipo-fectAMINE 2000. Distribution and expression of the fusion proteins encoded by JEV prME protein and BALB/c murine IgG Fc genes in transfected CHO cells were detected by immunofluorescence and Western blot. The BALB/c micc were vaccinated with pJME/IgG Fc via intramuscular injection. Then the cytotoxic T lymphocyt (CTL) activity were assessed by lactic dehydrogenase (LDH) and the neutralizing antibody titer were assessed by 80% plaque reduction neutralization test. Results Molecular weights (2001 bp, 2730 bp) of the two in- serts released from pJME/IgG Fc with two group of restriction analysis associated with BamH 1/EcoR I and BamH Ⅰ/Not Ⅰ were correlated to the expected theoretic results respectively. It was estimated that molecular weight (Mr) of the fusion protein was 101 x 103. The expression of the above fusion protein was mainly distribu- ted in endochylema of transfected CHO cells,and not much in membrane of transfected CHO cells. CHO cells transfected with pJME/IgG Fc could express the fusion protein at the 32th cell passage. After immunization, the CTL activity and the neutralizing antibody titer in the pJMF/IgG Fc vaccinated group increased significantly compared with other vaccinated groups(P <0.05). Conclusion The recombinant pJME/IgG Fc was construc- ted and transfected into CHO cells successfully, and CHO cellular lines expressed fusion protein encoded by JEV prME protein and BALB/c murine lgG Fc genes stably were obtained. IgG Fc gene could reinforce the cellular immunity and humoral immunity of JEV DNA vaccine.

Objective To study the adjuvant effect of granulocyte-macrophage colony-stimulating factor (GM-CSF) coding gene on cellular immunity induced by Japanese encephalitis (JE) virus DNA vaccine. Methods GM-CSF coding gene was amplified by nested-reverse transcriptase-polymerase chain reaction (RT-PCR) technique from BALB/c murine spleen cells. Recombinant plasmids pJME/GM-CSF and pGM-CSF were constructed by JE virus (JEV) prM-E protein with GM-CSF coding gene or GM-CSF coding gene only, respectively. The plasmids were transfected into China hamster ovary (CHO) cells by Lipofectamine 2000. The coding protein expressions and distributions were detected by immunofluorescence. The BALB/c mice were vaccinated with indicated immunogens with or without GM-CSF gene. The changes of T lymphocyte subsets in the spleen and levels of intracellular cytokines, such as interferon (IFN)-γ and interleukin (IL)-4 of splenic cells from mice immunized with different immunogens were evaluated by flow cytometry. The cytotoxicity T lymphocyte (CTL) activity was assessed by lactate dehydrogenase (LDH). The data were compared by one-factor analysis of variance and least significant difference. Results The constructed recombinant pGM-CSF and pJME/GM-CSF were confirmed by restrict enzyme digestion and DNA sequencing. The expressions of the above proteins were mainly in the cytoplasm and minor on cell membrane. The percentage of CD4+ T lymphocytes in pJME/GM-CSF vaccinated group was (33.90±0.79)%, which was significantly higher than that of in other groups (t values were 9. 818, 6. 804, 6.594, 10.061, 9.380, and 17.675, all P<0.05). The percentages of CD4+T lymphocytes in pJME +pGM-CSF (0) and pJME+pGM-CSF (-3) vaccinated groups were (29.83±0.61)% and (29.70±0.51)%, respectively, which were both higher than that in pJME+pGM-CSF (+3) vaccinated group of (27.69+0.50)% (t=3.466, t=3.255, both P<0.05). The percentages of CD8+ T cells in pJME/GM-CSF and pJME+pGM-CSF vaccinated groups were both higher than that in empty vector (pcDNA 3.1+) group and JE inactivated vaccine vaccinated group (t values were 3.811, 2.627, 10.537, and 3.811, all P<0.05). The CTL activity in pJME/GM-CSF vaccinated group was (51.48±0.10)%, which was higher than those in other groups (t values were 22.868, 13.823, 5.377, 32.287, 34.632, and 53.795, all P<0.05). The IFN-γ/IL-4 ratios in pJME/GM-CSF, pJME+pGM-CSF (0) and pJME + pGM-CSF (-3) vaccinated groups were (19.13±1.36), (12.32±0.82) and (7.05±0.43), respectively, which were higher than those in other groups (P<0.05). Conclusion GM-CSF coding gene could enhance the cellular immune response induced by Japanese encephalitis DNA vaccine.

Objective To observe the consistency of T-cell receptor (TCR) genes mutation in lymphocytes in rats after irradiation in vivo and in vitro.Methods A total of 48 female rats were randomly divided into 6 equal groups.Peripheral blood samples from them were collected to separate the lymphocytes and then irradiated to X-ray irradiation with the dose rate of 200 cGy/min at the doses of 0,0.5,0.75,1.0,2.0,and 3.0 Gy,respectively.Then all the lymphocyte samples were cultured for 7 days.Flow cytometry with direct immunofluorescence was used to detect the TCR gene mutation.The levels of TCR gene mutant frequency (TCRMF) of different groups were calculated.Results The TCRMF levels of different groups after irradiation in vivo and in vitro all displayed a dose-dependent manner and there were no significant differences in the TCRMF between different dose irradiation groups(t = -1.1-0.3 ,P ＞0.05).Conclusions A consistency of TCRMF after irradiation in vivo and in vitro is proven.The results of TCRMF of peripheral blood lymphocytes irradiated in vitro by flow cytometry can precisely reflect the TCR genes mutation after whole-body irradiation.

Objective To investigate the characteristic of movement disorders,so as to improve their diagnosis and treatment. Methods The clini?cal data of patients with movement disorders that admitted in the dystonia and Botox outpatient department were analyzed. Results Cases of involun?tary movement were significantly more than the primary dystonia,and case of primary hemifacial spasm was dominant(163 cases,61.05%). Among the 66 cases of primary dystonia,blepharospasm was ranked the first(19 cases),the second was spasmodic torticollis(18 cases),and the third was Meige syndrome(12 cases).There was no statistical significance in the gender distribution among primary hemifacial spasm,blepharospasm,spas?modic torticollis and Meige syndrome. Instead,there was statistical significance in the treatment methods(P<0.05),and there was statistical signifi?cance in the mean treatment and onset age(P<0.05). Of the 163 cases with primary hemifacial spasm,the mean onset age was 44.22±12.22 years, and the ratio of men to women was 1∶2.4. There were statistical significances in the mean onset age and duration among the patients with different severity degrees(all P<0.05). Conclusion Primary hemifacial spasm,blepharospasm,spasmodic torticollis and Meige syndrome are the com?mon disease in outpatient department. The primary hemifacial spasm is dominant,women are more than men,and the onset age and/or duration are proportional to the severity degree.
