Most clinical researchers participated in the clinical trials actively (86.9%) and they considered that the trials were helpful for them to enhance research ability and to issue paper.Conclusion Clinical researchers are familiar with GCP knowledge and can participate in the clinical trials actively. They still expect to learn more.

AIM: To obtain high level expression of recombinant human truncated osteoprotegerin (TOPG) with higher bioactivity in CHO-DHFR~-cells. METHODS: The recombinant vector pcDNA3.1/DHFR-TOPG was constructed and transfected into CHO-DHFR~- Cells by the directions of LipofectAMINE~(TM)2000 for stable expression. The stable expression cell strains were screened by selective medium IMDM with 50 mL/L FCS, then serially passed in methotraxate (MTX) for gene amplification. The expression were analyzed by ELISA and RT-PCR. At last, the bioactivity analysis was performed in vitro. RESULTS: The expression level of recombinant truncated human OPG was up to 6 mg/L·72 h, and it had significant suppression effect on the formation of OLC(P<0.05). CONCLUSION: Recombinant truncated human OPG has high expression and bioactivity. The results make it possible for further studying and clinical implying of OPG.

Objective To explore the relationship between TGF-beta1,BRCA2,HER2,ER,PR and clinical factors in breast cancer.Methods The expression of TGF-beta1,BRCA2,HEB2,ER,PB in 67 cases breast carcinoma were detected by immunohistochemistry staining SP method.The correlation of the results with other parameters which included age,pathohistological grade,status of auxiliary lymph nodes were analyzed by mono-factor unconditional logistic regression analysis.Results The expression of TGF-beta1 was correlated with BRCA2.and the expression of BRCA2 was correlated with TGF-beta1 and c-erbB-2 in breast cancer.Condusion Overexpression of BRCA2 was related with TGF-beta1 and HER2 in breast carcinoma.It was useful in breast carcinoma prognosis by detecting these three factors.

Objective To explore the characteristic findings of 1H-MR spectroscopy(1H-MRS) in the prefrontal cortex and amygdala of patients with heroine dependence(HD), and the relationship to total cumulative dose of inhaled heroine.Methods Fourteen male HD patients and 12 healthy controls (HC) underwent 1H-MRS at the prefrontal cortex and amygdala regions.The total cumulative in haled heroin dose was (852±341) g in HD.Ratios of N-acetylaspartate/creatine(NAA/Cr) and choline/creatine (Cho/Cr) were respectively measured in the prefrontal cortex and bilateral amygdale regions.The student's t test and the linear correlation were employed for statistical analysis.Results Compared to HC group, HD patients had a significant lower ratio of NAA/Cr in the prefrontal cortex (1.44±0.46 vs 1.50±0.75, t=1.77 ,P <0.05), left amygdala region (1.32±0.08 vs 1.42±0.08, t=3.41, P < 0.05), and right amygdala region (1.34±0.09 vs 1.44±0.10, t=2.63, P <0.05), the HD patients had a significant increased ratio of Cho/Cr in the prefrontal cortex (0.92±0.06 vs 0.86±0.08, t=2.31, P < 0.05), left amygdala region (1.20+0.12 vs 1.07±0.04, t=3.60,P<0.05) and right amygdala region(1.26±0.15 vs 1.12±0.11,t=2.60,P <0.05).There was a negative linear correlation between the total cumulative inhaled heroine dose and the ratio of NKA/Cr in the prefrontal cortex (r=-0.9159, P < 0.01), left amygdala region (r=-0.8756, P < 0.01), and right amygdala region (r=-0.9399, P < 0.01) respectively.Conclusions The study indicates that neuronal damage and glial proliferation may occur in the prefrontal cortex and amygdala region, which suggests the abnormalities of executive function and emotion in patients with HD.A relationship exists between the heroin-induced metabolic abnormality and the total cumulative dose of inhaled heroine.

BACKGROUND:Studies have shown that bone marrow mesenchymal stem cells have the ability to persistently generate hepatocytes and biliary cells, and thus in the repair process of liver injury, replenish the reduced number of hepatocytes due to damage and participate in damaged liver structure.
OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cells transplantation on acute liver failure and the expression of CD163 and interleukin-10 in rat serum and liver tissue.
METHODS:D-galactose and lipopolysaccharidewere used to make acute liver failure models in 60 Sprague-Dawley rats. Then, the rats were divided into control group and transplantation group. Bone marrow mesenchymal stem cells at passage 3 were injected through tail vein in the transplantation group, and normal saline was injected in the control group. After transplantation 24, 120, 168 hours, serum samples and liver tissues were col ected.
RESULTS AND CONCLUSION:After transplantation 120 and 168 hours, the serum alanine transaminase and aspartate aminotransferase activities of the transplantation were significantly lower than those of the control group (P<0.05). In the transplantation group the apoptotic index was stil lower compared with the control group, and the difference was significant (P<0.05). The levels of CD163 and interleukin-10 in the serum and liver tissue in the transplantation group were decreased significantly compared with the control group (P<0.05). The results suggested that there were highly significant correlations between CD163 and interleukin-10 (P<0.01). Bone marrow mesenchymal stem celltransplantation has a therapeutic effect on acute liver failure rats. CDl63 and interleukin-10 play a very important role in the pathogenesis of acute liver failure, which can be used as sensitive serum marker proteins for diagnosis and prognosis of acute liver failure.

Objective To investigate radioactivity levels in the main agriculture products around a uranium mine in Northern Guangxi.Methods The agriculture products and soil samples were collected and analyzed by using HPGe gamma ray spectrometer.Results The specific activity of 226Ra in radish (including leaf),radish leaves and radish,collected in one place,were 45.0,66.7 and 32.3 Bq/kg,respectively.Those of 226Ra and 23SU in the radish soil collected in the same place were 19 672 and 85 917 Bq/kg,respectively.The transfer coefficients of soil-to-radish and soil-to-leaves were 1.61 × 10-3 and 3.40 × 10-3,consistent with those reported in relevant literature.Radioactivity levels in agricultural products in another survey was in consistence with those in the national survey for food products.Radioactivity levels in soil elsewhere near the radish site was consistent with the results of the national soil radioactivive background survey.Conclusions The soil in this place has been contaminated by the nearby uranium mine.It is important to investigate this place further and take the necessary measures.

Objective To investigate the clinical distribution and antimicrobial resistance of common gram-positive cocci in author's hospital.Methods Identification of these bacteria were done with API analysis system,disc diffusion tests were employed to study the antimicrobial resistance.Results A total of 25 052 clinical isolates were collected in 8 years,of gram-positive cocci accounted for 7907(31.9%).Staphylococcus aureus(3549 strains,44.9%),enterococcus(1760 strains,22.3%)and coagulase-negative staphylococcus(1558 strains,19.7%)were the most common isolates.The prevalence of MRSA increased from 59.6% in 2001 to 76.3% in 2008,and MRSCoN increased from 64.2% to 77.0%.The resistant rate of MRSA to gentamicin,clindamycin,erythromycin and levofloxacin were over 90%,to trimethoprim/sulfamethoxazole and chloramphenicol were less than 20%.The resistant rate of MSSA to gentamicin,levofloxacin,trimethoprim/sulfamethoxazole and chloramphenicol were low 20%,and to beta-lactamase antibacterial agents except penicillin were 0.The resistant rates of MRSCoN to all antimicrobial agents were lower than MRSA,but to trimethoprim/sulfamethoxazole(71.2%)was higher than MRSA(21.2%).No staphylococcus strains were resistant to vancomycin,teicoplanin and linezolid.2.1% enterococcus feacium and 4.4% other enterococcus were resistant to vancomycin.No strains of enterococcus were found resistant to teicoplanin and linezolid.Conclusion The resistant rate of gram-positive cocci were increasing obviously,the prevalence of MRS was high.Vancomycin,teicoplanin and linezolid were the most active agents against severe infection induced by multidrug-resistant gram-positive cocci.
