Objectives Selecting and constructing the biofilm -model of Pseudomonas aeruginosa in vitro.Observing the antibacterial activity of using Micafungin alone , or combined with Meropenem against Pseudomonas aeruginosa ( plankton-grown and biofilm-grown ) . Methods Ten clinical isolates of Pseudomonas aeruginosa were collected in July 2012, constructing the biofilm-model by microwell plate from Xiangya Hospital, Central South University.The ability of biofilm-formation of these strains was estimated by crystal violet colorimetric method, and optical microscope was used to observe the shape of the biofilm .MICs of Micafungin and Meropenem against plankton -grown and biofilm-grown Pseudomonas aeruginosa were tested by broth microdilution method, and the changes of MICs were compared.Using broth microdilution method, and connecting with the crystal violet colorimetric method , to observe the antibacterial effect of using Micafungin alone, or combined with antibiotics in the inhibition of the biofilm formation and destruction of mature biofilm of Pseudomonas aeruginosa.SPSS18.0 and t-test were used in comparing the differences between both treatment group and control group.P <0.05 showed the difference was statistically significant . Results Ten strains of Pseudomonas aeruginosa were successful in forming biofilms.Comparing with their planktonic counterparts, biofilms became more resistant to Meropenem , with the MIC raised 4-128 times. However, MIC of Micafungin could not be measured.Micafungin can inhibit the formation of biofilm in 9 experimental strains (PA1-PA9), where the minimum effective concentration of Micafungin were 156.25, 625, 10 000, 2 500, 1 250, 2 500, 1 250, 625 and 10 000 mg/L respectively.The absorbance values of the minimum effective concentration group and its positive growth control group were 0.342 ±0.020 vs 0.491 ±0.027, 0.512 ±0.018 vs 0.627 ±0.043, 0.862 ±0.021 vs 1.155 ±0.027, 0.731 ±0.028 vs 0.863 ± 0.017, 0.311 ±0.003 vs 0.447 ±0.021, 0.435 ±0.021 vs 0.597 ±0.011, 0.520 ±0.012 vs 0.605 ± 0.027, 0.611 ±0.059 vs 0.734 ±0.017, 0.223 ±0.011 vs 0.343 ±0.037 respectively, where the P values were 0.02, 0.03, 0.00, 0.01, 0.01, 0.00, 0.03, 0.01 and 0.03 respectively.The differences are statistically significant.Micafungin can damage the mature biofilm of 7 strains (PA1, PA2, PA4 -PA8), where the minimum effective concentration of Micafungin were 2 500, 2 500, 5 000, 2 500, 5 000, 2 500, 5 000 mg/L respectively.The absorbance values of the minimum effective concentration group and its positive growth control group were 1.459 ±0.014 vs 1.534 ±0.020, 1.279 ±0.020 vs 1.431 ±0.007, 1.365 ±0.024 vs 1.467 ±0.065, 1.322 ±0.028 vs 1.530 ±0.090, 0.920 ±0.004 vs 1.047 ±0.013, 1.860 ±0.005 vs 1.953 ±0.055, 1.407 ±0.005 vs 1.553 ±0.045 respectively, where the P values were 0.01, 0.01, 0.02, 0.01, 0.00, 0.03, 0.02.The difference is statistically significant.Micafungin combined with Meropenem applied in multiple drug resistant strains , which can inhibit the formation of biofilm better.Conclusions Micafungin can inhibit the formation Pseudomonas aeruginosa biofilm and damage the mature biofilms.Micafungin combined with Meropenem can act on multiple drug resistant strain , which may get a higher inhibition rate of the biofilm.

Objective To investigate the role of PPAR-γ in the gene expression of T-bet/GATA-3 in Jurkat T cells,and to explore the mechanisms underling this sensitizing effect of the change of TH cell subpopulation group.Methods Jurkat T cells were stimulated with PPAR-γ agonist pioglitazone.TH cell related cytokine IFN-γ and IL-10 was detected by ELISA,and the expression of transcription factors(T-bet and GATA-3)mRNA was detected by RT-PCR.To prove the PPAR-γ-dependent effect.the PPAR-γ-specific antagonist GW9662 was used.Results Stimulated with agonist PPAR-γpioglitazone.the concentration of IFN-γ and IL-10 and the expression of transcription factor T-bet and GATA-3 mRNA were both significantlY decreased in Jurkat T cells obviously,and these actions were dependent on the time and the concentrations of pioglitazone.Added with antagonist GW9662 at the same time,such inhibitory actions of IFN-γ and T-bet expression were recovered.but not IL-10 and GATA-3.Conclusion Pioglitazone can inhibite T cells proliferation and their secretion of cytokines.Pioglitazone can inhibit TH1 cells from secreting cytokines,and it is a PPAR-γ-dependent effect related to T-bet.The inhibition on TH2 is not a PPAR-γ-dependent effect and it is GATA-3 related.

OBJECTIVE: To investigate the immunoregulation and short-term therapeutic effects of super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules, a compound Chinese herbal medicine, on patients with late gastric cancer. METHODS: Forty patients with late gastric antrum cancer were randomly divided into study group and control group. Patients in the study group were orally administered Fuzheng Kang'ai Granules 48 hours after the first super-selective left gastric artery chemotherapy with high-dose drugs (EAP regime: VP(16) 100 mg/m(2) + epirubicin 60 mg/m(2) + carboplatin 200 mg/m(2)), while patients in the control group were only administered the same local artery chemotherapy as in the study group. RESULTS: The short-term therapeutic efficacy in the study group and control group were 82.5% and 57.5% respectively (P<0.01). The occurrence rates of side effects in the study group were significantly lower than those in the control group (P<0.01). The Karnofsky score of life quality of the study group was obviously higher than that of the control group after treatment (P<0.05). The half survival time and one year survival rate in the study group and control group were (24.9 +/- 1.36) month, 70% (28/40) and (13.7 +/- 0.72) month, 35% (14/40) respectively. They were significantly improved in the study group compared with the control group (P<0.01). The levels of cytokines interleukin 2 (IL-2), tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) after treatment in the study group were significantly higher than those before treatment (P<0.05 or P<0.01), as well as than those after treatment in the control group (P<0.01). On the other hand, the level of immune inhibitory factor soluble interleukin-2 receptor (sIL-2R) after treatment in the study group was lower than that before treatment, as well as than that after treatment in the control group (P<0.01). CONCLUSIONS: The super-selective intra-arterial chemotherapy combined with Fuzheng Kang'ai Granules has good short-term therapeutic efficiency and few side effects for patients with late gastric antrum cancer. It can significantly improve the life quality, extend the survival period, and improve the survival rate in patients with late gastric antrum cancer, which may be due to the up-regulation of the immune regulating factors such as IL-2, TNF-alpha, IFN-gamma and down-regulation of the immune inhibitory factor sIL-2R.

Objective To study the clinical significance of the serum angiopoietin-2(Ang-2) in the diagnosis,recurrence,invasion and metastasis of gastric cancer.Methods The serum Ang-2 and carcino-embryonic antigen (CEA) levels in 158 patients with gastric cancer (gastric cancer group) and 30 normal controls(control group) were measured by enzyme linked immunosorbent assay(ELISA) technique respectively.The serum Ang-2 and CEA levels were also measured 2 weeks after operation in gastric cancer group and reexamined in the recurred gastric cancer patients in 2 years after operation (recurred and metastasis group).The correlation between the serum Ang-2 level and pathologic c haracterization of gastric cancer was evaluated.Results The serum Ang-2 and CEA levels in gastric cancer group [ (331.8 ±64.3),(42.6 ±37.3)μg/L] and recurred and metastasis group [(318.7 ±72.9),(40.5 ±36.7)μg/L] were significantly higher than those in control group [ (187.4 ± 32.7),(4.2 ± 3.1 )μ g/L] (P ＜ 0.01 ),and the serum Ang-2 level 2 weeks after operation [ (211.6 ± 75.1 ) μ g/L ] was significantly decreased to the control group (P ＞ 0.05 ),while the serum CEA level [ (33.4 ± 30.6) μ g/L ] was still significantly higher than the control group (P ＜ 0.01 ).The sensitivity of the serum Ang-2 for diagnosis of gastric cancer was markedly higher than that of the serum CEA (P ＜ 0.01 ).There was correlation between serum Ang-2 and degree of tumor differentiation,TNM pathological staging,lymphatic metastasis,invasion depth and tumor size (p ＜0.01 ),but there was no correlation between serum Ang-2 and tissue classification and location of gastric cancer (P＞ 0.05).Conclusion The serum Ang-2 level is suggested to be a valuable gastric cancer marker and conduce to the diagnosis of gastric cancer,the monitoring of recurrence after operation and evaluation of prognosis.
