BACKGROUND: Wuhuang oil has a bacteriostatic action to treat burn wound and promote traumatic healing, but the action on inhibition of scars formation remains poorly understood.OBJECTIVE: To investigate the effects of modified Wuhuang oil at different concentrations and administration times on the growth and proliferation of human fibroblasts in vitro.DESIGN, TIME AND SETTING: Comparison observation regarding cytology in vitro was performed at the Burns Institute in the First Affiliated Hospital of Nanchang University between April 2006 and January 2007.MATERIALS: Prepuce specimens were harvested from patients who underwent circumcision in Department of urinary surgery, at First Affiliated Hospital of Nanchang University and Jiangxi Provincial Children Hospital. All patients aged 2-12 years old, and informed consents were obtained from their relatives. Wuhuang oil and modified Wuhuang oil (water-solubility) were offered by Department of Pharmaceutical Preparation in the First Affiliated Hospital of Nanchang University, China. METHODS: Human fibroblasts cultured in vitro were divided into 2 groups at random, experiment and control. Experiment group was treated with 300 g/L Wuhuang oil, while control group with 300 g/L modified Wuhuang oil. Serum-free culture fluid was used to prepare 6 concentrations of oil solution: 0 (blank control), 100, 150, 200, 250, 300 g/L.MAIN OUTCOME MEASURES: MTT assay was used to determine the growth and proliferation of human fibroblasts at 2, 3, 4, 5,6 days; inhibition rate of cell growth was observed at 2, 4, 6, 8, 10 days.RESULTS: Modified Wuhuang oil (0-300 g/L) concentration positively correlated with inhibition of human fibroblast proliferation;the inhibition was not related to culture time. Modified Wuhuang oil (300 g/L) had the greatest inhibition rate of human fibroblasts at 8-10 days, there were significant differences between experiment group and control group (P < 0.01).CONCLUSION: Modified Wuhuang oil has an effective inhibition on the proliferation of human fibroblasts in vitro, and shows a dose-dependent tendency. Compared with Wuhuang oil, 300 g/L modified Wuhuang oil is superior to suppress the growth of human fibroblasts.

Although there is emerging evidence that BJ46a can function as potent inhibitor of the SVMPs proteolytic activities,its anticancer effect on invasion and metastasis has not yet been evaluated.Inhibition effect of BJ46a on experimental pulmonary metastasis in mice inoculated with B16 melanoma cells at the protein level was investigated. First,BJ46a was produced in baculovirus expression system. SDS-PAGE and Western blot analysis confirmed that BJ46a recombinant protein was produced by Sf9 cells infected with high-titer viral stock. Then,recombinant fusion protein was purified by ProBondTM at the point of maximal expression. B16 cells pre-treated with recombinant BJ46a injected into C57BL/6 mice via the tail lateral vein to form experimental pulmonary metastasis model. The numbers of metastatic lesions in C57BL/6 mice changed dramatically:BJ46a different concentrations of recombinant protein group were 1.1 ? 0.83,0.9 ? 0.7,significantly lower than the control group (6.3?3.00,P

Results All 245 surgeries were successfully completed. The mean operation time was 59 (20-250) min and the estimated blood loss was 5-300 ml with no transfusion. There was no serious complication during perioperative period. Conclusion Retroperitoneal laparoscopic resection and re-conatruetive surgery in urology is safe and effective with the advantages of minimal invasion, quick re-covery and few complications.

Objective To explore the role and clinical significance of GSTM 3 ( glutathione S-trans-ferase mu 3) expression in prostate cancer (PCa). Methods We had used the two-dimensional fluores-cence difference gel electrophoresis ( 2D-DIGE) and mass spectral analysis to further verify the microarray data of mRNA expression profiling discovered .GSTM3 mRNA level was detected by Rael-time Quantitative PCR ( RT-QPCR) in 28 pairs of prostate cancer tissue and benign tissue .The relationship of GSTM 3 level with the serum PSA level and the clinical feature of PCa were analyzed . Results In 2D-DIGE study, we found that the expression of GSTM 3 protein in adjacent tissues was significantly higher than that in PCa tis-sues (P<0.05).RT-QPCR results showed that GSTM3 in adjacent tissues (8.12±0.51) was significantly higher than that in PCa tissues (7.18±0.54) (P<0.05).There was no significant difference of GSTM3 ex-pression in different serum PSA packets ( P>0.05) and prostate cancer clinical pathological parameters ( P>0.05). Conclusions GSTM3 expression is down-regulated in PCa tissues, and we may identify PCa by detecting the GSTM 3 expression .

Aim To detect the expression of hippocam-pus NGF gene in the mouse model of Parkinson 's dis-ease. Methods By intraperitoneal injection of 1-meth-yl-4-phenyl-1,2, 3, 6-tetrahydropyridine ( MPTP), a mice model of Parkinson ’ s disease was established. The success of PD model was identified by detecting the expression of mesencephalic tyrosine hydroxylase ( TH) with Western blot and immunofluorescence. The movement and cognitive ability of mice were evaluated by foot print analysis and step-through passive avoid-ance test. The expression of NGF gene in hippocampus of mice was detected with RT-PCR and in situ hybrid-ization. Results Compared with the control group, the levels of TH and NGF were reduced in the experi-mental group and the behavioral indexes were deflected significantly. Conclusion NGF may play an impor-tant role in the occurrence and development of the PD cognitive disorder.

Objective:To evaluate the efficacy and safety of sequential platinum regimen in young patients with diffuse large B-cell lym-phoma (DLBCL). Methods:Newly diagnosed young patients with DLBCL, who were hospitalized from January 2005 to June 2012 in the Affiliated Cancer Hospital of Zhengzhou University, were selected according to the requirements. The patients were divided into stan-dard and sequential platinum regimen groups. The remission rates were compared usingχ2 test, whereas the five-year survival rates between the two groups were compared using the Kaplan–Meier method. Multivariate survival analysis was performed using the Cox proportional regression. Subgroup analysis was conducted to select candidate patients for the sequential platinum regimen. Results:A total of 331 patients were enrolled in the study, in which 129 were provided with sequential platinum regimen and 202 were provided with the standard regimen. Sequential regimen yielded higher rates of complete remission (80%vs. 63%, P=0.001), five-year progres-sion-free survival (PFS;60%vs. 50%, P=0.014), and overall survival (OS;70%vs. 58%, P=0.016) than the standard regimen. Multivariate analysis revealed that sequential regimen was an independent prognostic factor for PFS (hazard ratio HR=0.635, P=0.012) and OS (HR=0.625, P=0.021). Subgroup analysis showed that patients with good prognosis and patients who did not receive rituximab benefited more from the sequential platinum regimen. Sequential platinum regimen did not increase the occurrence of adverse effects com-pared with the standard regimen. Conclusion:Sequential platinum regimen is a safe treatment that can improve the survival of young patients with DLBCL. Patients with good prognosis and patients who did not receive rituximab can benefit more from the treatment with sequential platinum regimen.
