In perspective, local Public Administrations （PA） may represent the reference target for the introduction of IPSAS standards but a direct application in the short-run can hardly be imagined in the Italian context. According to the CFOs of medium-small Municipalities in the Lazio Region, the IPSAS enforcement strategy swings between the ＂forced＂ model and the ＂spontaneous＂ model. The application of IPSAS standards to Italian PAs depends on specific law provisions at all institutional levels and requires a process of implementation based on a bottom-up model ＂governed by the center＂.展开更多

METHODS: The human colorectal cancer (CRC) cell lines HT29 and SW480 were treated with nigericin or oxaliplatin under the conditions specified. Cell viability assay and invasion and metastasis assay were performed to evaluate the effect of nigericin on CRC cells. Sphereforming assay and soft agar colony-forming assay were implemented to assess the action of nigericin on the cancer stem cell properties of CRC cells undergone epithelial-mesenchymal transition (EMT). RESULTS: Compared with oxaliplatin, nigericin showed more toxicity for the HT29 cell line (IC50, 12.92 ± 0.25 μmol vs 37.68 ± 0.34 μmol). A similar result was also obtained with the SW116 cell line (IC50, 15.86 ± 0.18 μmol vs 41.02 ± 0.23 μmol). A Boyden chamber assay indicated that a significant decrease in the number of HT29 cells migrating through polyvinylidene fluoride membrane was observed in the nigericin-treated group, relative to the vehicle-treated group [11 ± 2 cells per high-power field (HPF) vs 19.33 ± 1.52 cells per HPF, P < 0.05]. Compared to the control group, the numbers of HT29 cells invading through the Matrigel-coated membrane also decreased in the nigericin-treated group (6.66 ± 1.52 cells per HPF vs 14.66 ± 1.52 cells per HPF, P < 0.05). Nigericin also reduced the proportion of CD133+ cells from 83.57% to 63.93%, relative to the control group (P < 0.05). Nigericin decreased the number of spheres relative to the control group (0.14 ± 0.01 vs 0.35 ± 0.01, P < 0.05), while oxaliplatin increased the number of spheres relative to the control group (0.75 ± 0.02 vs 0.35 ± 0.01; P < 0.05). Nigericin also showed a decreased ability to form colonies under anchorage-independent conditions in a standard soft agar assay after 14 d in culture, relative to the control group (1.66 ± 0.57 vs 7 ± 1.15, P < 0.05), whereas the colony numbers were higher in the oxaliplatin group relative to the vehicle-treated controls (14.33 ± 0.57 vs 7 ± 1.15, P < 0.05). We further detected the expression of E-cadherin and vimentin in cells treated with nigericin and oxaliplatin. The results showed that HT29 cells treated with nigericin induced an increase in E-cadherin expression and a decrease in the vimentin expression relative to vehicle controls. In contrast, oxaliplatin downregulated the expression of E-cadherin and upregulated the expression of vimentin in HT29 cells relative to vehicle controls. CONCLUSION: This study demonstrated that nigericin could partly reverse the EMT process during cell invasion and metastasis.展开更多

Methods： ERCC1 Asn 118Asn polymorphism was analyzed in 99 patients with stages Ⅲ and Ⅳ advanced colorectal cancer treated with oxaliplatin-based chemotherapy, For all of the patients, ERCC1 Asnl18Asn genotype was analyzed for associations with treatment response and time to disease progress （TTP）. Results： The allele frequencies of the ERCC1 gene codon 118 were C/C 50.51% （50/99）, C/T 41.41% （41/99）, T/T 8.08% （8/99）, respectively. Patients with C/C genotype showed higher response rate than those with C/T ＋ T/T （OR = 3.764, 95% CI： 1.310-10.813）. The median TTP of all patients was 7 months （95% CI： 5.569--8.431）. Patients with C/C genotype showed a median TTP of 10 months （95% CI： 8.924-11.076）, which was longer than 5 months （95% CI： 4.424-5.576） in patients with C/T ＋ T/T genotypes. Conclusion： Our results showed a link between ERCC1 Asn118Asn genetic polymorphism and cancer response to oxaliplatin-based chemotherapy and time to disease progress in Chinese patients with advanced colorectal cancer. ERCC1 Asn 118Asn genotyping may be of predictive benefit in selecting treatment regimen for advanced colorectal cancer.展开更多

METHODS From January 2002 to November 2005, 59 patients with advanced colorectal cancer confirmed by pathology were enrolled into this study in the department of medical oncology, in the Sixth People＇s Hospital of Shanghai Jiaotong University, Shanghai. Patients＇ characteristics in two groups were similarly confirmed by statistic. All 37 patients in OH group received oxalip21atin （130 mg/m^2 d1） plus hydroxycamptothecine （6 mg/m d1-4）, and all 22 patients in the HLF group received hydroxycamptothecine （6 mg/m^2 d1-4） plus leucovorin （300 mg d1-5） and 5-fluorouracil （0.375 g/m^2 d1-5）. The regimens in both groups were 21-day cycle that was repeated three weeks. The side effects were evaluated. The efficacy was estimated after two cycles of chemotherapy for each patient. RESULTS The efficacy of the treatment in the OH group with 37 patients and in the HLF group with 22 patients was estimated. The overall response rate （CR ＋ PR） was 32.4% in the OH group and 22.7% in the HLF group. There was no complete response （CR） and there was no statistical significantly difference （%2= 0.876, P = 0.704） in two groups. The 1-year survival rate was 30.98% in the OH group and 15.02% in the HLF group, and it had no significant difference between the two groups. The median PSF and OS were 5.83 months and 11.17 months in the OH group vs. 7.40 months and 10.48 months in the HLF group, and it had no significant differences between the two groups （P 〉 0.05）. The major side effects of grade III and IV in the two groups were myelosuppression and gastrointestinal reactions. The statistically significant difference in side effects appeared in leukopenia （χ^2= 17.173, P = 0.001）, nausea/vomiting （χ^2= 6.426, P = 0.039）, diarrhea （χ^2= 16.245, P = 0.000） and peripheral neuropathy. CONCLUSION The efficacy was almost equal between the OH and the HLF groups, and the two regimens can be used as the second-line treatments for the patients with colorectal cancer. Leucopenia, nausea, diarrhea and peripheral neuropathy appeared more in OH group, and anemia and thrombocytopenia were almost equal between the OH and the HLF groups.展开更多

This paper describes its history,, from the first concert performed by the American jazz musician George Lewis and His New Orleans Orchestra to the turbulent and economical difficult years in the 1970＇s when the owner, Herluf Kamp-Larsen, had to declare himself bankrupt. A couple of Danish jazz musicians, trumpet player Palle Mikkelborg （1941-） and pianist Ole Kock Hansen （1945-）, explain the importance of the venue, and some of the most legendary jazz musicians that were hired during the clubs history are mentioned. The paper is based upon the author＇s book upon the venue and gives a survey of the history of Montmartre Jazz House. The research for the book includes lots of concert reviews, interviews with many musicians, members of the staff and Herluf Kamp-Larsen, and besides, the writer had access to the archive of the jazz house.展开更多

Relationships of average grain size to soaking temperature and time were obtained respectively. The results show that the prior austenite grains grow with the increase of soaking temperature and time. When soaking temperature is lower than 1 180 ℃, austenite grain size and growth rate are small; when it higher than 1 200 ℃, austenite grains grow rapidly and abnormal grain growth appears. For soaking at 1 180 ℃, austenite grain growth rate is initially high and then decreases when soaking time exceeds 1 h.展开更多

Methods： The blood pressure-decreasing effects of single administration and 14-day consecutive administration of Compound Mistletoe Fluidextract （CMF） in SHR and RHD were investigated and compared with that of Niuhuang Jiangya Wan （牛黄降压丸 Bezoar Hypertension-relieving Pills）. Results： Both single administration and 14-day consecutive administration of CMF had significant hypotensive effects in SHR and RHD. Conclusion： The hypotensive action of CMF is gradual, but lasts for a longer period, with a dose-effect relationship in a range of doses.展开更多
