Objective: To observe the expression of cellular FLICE-like inhibitory protein long form (cFLIPL) mRNA in colon cancer and to assess its relationship with the biological behavior and prognosis of colon cancer. Methods: Expression of cFLIPL mRNA was examined in 86 colon cancer samples and their corresponding normal tissues by semi-quantitative RT-PCR technique. Expression of CEA and P53 in the colon cancer samples was assayed by SABC immunohistochemistry staining. The plasma levels of CEA and CA19-9 were determined by microparticle enzyme-linked immunoassay (MEIA) before operation. Colon cancer tissues were divided into cFLIPL mRNA high expression group and low expression group based on the average value of all the 86 patients. The relationship between the high expression of cFLIPL mRNA and the different clinical features and pathological characters was determined. We also compared the 5-year accumulative survival rates of the 2 groups. Results: The expression of cFLIPL mRNA in the colon cancer tissues was significantly higher than that in the matched normal tissues (0.59±0.10 vs 0.36±0.10, P

Objective To compare the success rate, time of tumor formation and number of tumors in three methods of tumor transplantation, in order to seek an ideal animal model for molecular imaging study. Methods Forty-eight BALB/C-nu/nu nude mice were randomly divided into three groups (each n=16). Tumor tissue mass of 2 mm3 was injected into subcutaneous of nude mice in experiment group. Tumor tissue mass of 1 mm3 was applied in control group 1. Tumor cells suspension liquid was injected into subcutaneous of nude mice in control group 2. The tumor formation rate, the time of tumor formation and the number of tumors were observed. MRI scanning were performed 3-6 weeks after implantation. Results The rate of tumor formation of three groups was 93.75%, 75.00% and 43.75%, respectively. The time of tumor formation was (21.7±2.4), (29.8±2.9) and (34.6±3.9) days, respectively. The rate of solitary nodule implanted tumor was 93.33% in experiment group, higher than that in control group 1 (75.00%) and control group 2 (14.29%). The tumors were hypointense on T1WI and hyperintense on T2WI. Conclusion Transplantation 2 mm3 tumor tissue mass is effective to set up the subcutaneous implanted tumor models with a high success rate of tumor formation, a short time of tumor formation and high rate of solitary tumors, being suitable for the study of molecular imaging. The models can undertake conventional T1WI, T2WI and T2-mapping imaging, and the imaging qualities are good.

Background: Integrative traditional Chinese and western medicine may be a new approach to improve the eradication rate of Helicobacter pylori (Hp).Aims: To compare the efficacy and safety of Weifuchun tablet versus bismuth combined with standard triple regimen as the first-line therapy of Hp infection.Methods: A total of 141 patients with Hp infection and na(i)ve to treatment were randomly assigned into 3 groups receiving a 14-day eradication therapy.In standard triple therapy group, esomeprazole, amoxicillin and clarithromycin were given twice a day;while in Weifuchun group and bismuth group, Weifuchun tablet and bismuth potassium citrate were added, respectively, to the standard triple therapy.Hp eradication was assessed by 13C-urea breath test at least 6 weeks after the end of treatment.Hp isolates were tested for resistance to antibiotics.Results: One hundred and twenty-eight patients completed the study.Hp eradication rates in Weifuchun group, bismuth group and standard triple therapy group were 83.7%, 91.8% and 79.1%, respectively by ITT analysis and 88.4%, 97.8% and 84.6%, respectively by PP analysis.The eradication rate of Weifuchun group was lower than that of bismuth group and higher than that of standard triple therapy group, but the differences were not statistically significant (P>0.05).Only PP eradication rate of bismuth group was significantly higher than that of standard triple therapy group (P<0.05).The resistant rates of Hp to clarithromycin, amoxicillin and metronidazole were 33.3%, 2.9% and 70.5%, respectively.For eradication of clarithromycin resistant strains, bismuth group was superior to Weifuchun group and standard triple therapy group (100% vs.60.0% and 66.7%, P all <0.05).All three eradication regimens showed good compliance, and no significant difference in incidence of adverse events was found between the three regimens (P>0.05).Conclusions: Weifuchun tablet combined with standard triple regimen is safe and effective for use as first-line treatment for Hp infection, however, the eradication rate is relatively low in cases infected with clarithromycin resistant strains.Bismuth combined with standard triple regimen is a good alternative in areas with high clarithromycin resistance and regions where tetracycline is unavailable.

Objective:To conduct health economic evaluation of Chinese population-based screening and opportunistic testing strategies for the prevention of Helicobacter pylori ( H. pylori)-related diseases. Methods:The Markov models of H.pylori infection caused non-ulcer dyspepsia, peptic ulcer (PU) and gastric cancer were established. The cost and effects of the population-based screening, opportunistic testing, and non-intervention strategies in 100 000 population of our country were simulation calculated. Wilcoxon signed rank test was used for statistic analysis. Single factor sensitivity analysis was performed to analyze the impact of single parameter uncertainty on cost-effectiveness. Probability sensitivity was used to analyze the impact of common uncertainty of all parameters on cost-effectiveness. Results:Compared with opportunistic testing strategy and non-intervention strategy, the total cost of population-based screening strategy was reduced by 0.43 million yuan(-6.63 million yuan to 7.19 million yuan) and 4.45 million yuan(-8.60 million yuan to 27.93 million yuan), quality adjusted life years (QALY), life years and asmptomatic months were prolonged by 888.00 (479.86 to 1 574.10) and 3 032.78 (1 756.04 to 5 007.84), 651.82 (294.73 to 1 211.94) and 1 868.64 (1 045.88 to 3 148.34), 28 381.91 (19 109.54 to 43 736.72)and 102 537.13 (58 649.18 to 176 868.77) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 115 cases(52 cases to 232 cases) and 464 cases(266 cases to 803 cases), 74 cases(33 cases to 148 cases) and 260 cases(149 cases to 453 cases), 46 cases(25 cases to 72 cases) and 369 cases(210 cases to 710 cases), 80 cases(42 cases to 126 cases) and 501 cases(331 cases to 772 cases) respectively, and the differences were statistically significant ( Z=1.99, 10.54, 27.39, 27.39, 27.37, 27.39, 27.39, 27.39, 27.21, 27.28, 27.22, 27.28, 27.38, 27.39, 27.39 and 27.39, all P<0.05). Compared with the non-intervention strategy, the opportunistic testing strategy reduced the total cost by 3.89 million yuan(-2.79 million yuan to 18.18 million yuan), QALY, life years and asymptomatic months were prolonged by 1 764.77 (888.70 to 3 406.62), 1 044.16 (524.46 to 1 912.75) and 62 568.69 (30 054.07 to 129 892.76) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 311 cases(164 cases to 563 cases), 164 cases (87 cases to 301 cases), 325 cases(162 cases to 644 cases) and 399 cases(234 cases to 684 cases) respectively, and the differences were statistically significant ( Z=14.20, 27.39, 27.38, 27.39, 27.25, 27.25, 27.39 and 27.39, all P<0.01). The results of singlefactor sensitivity analysis showed that the uncertainty of any parameter did not affect the cost-effectiveness of three strategies. The results of probability sensitivity analysis indicated that the probability of cost-effectiveness advantage of the population-based screening strategy was 100% and the common uncertainty of all parameters had no effect on cost-effectiveness. Conclusions:For preventing H.pylori-related diseases, the population-based screening strategy has the lowest average cost and the best average effect. However, non-intervention strategy has the highest average cost and the worst average effect. Population-based screening strategy is worthy of promotion throughout China, and opportunistic testing strategy has a higher clinical practical value.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

Objective To analyze the frequency of NPM1 mutation in de novo acute myeloid leukemia (AML) patients and the relationship between NPM1 mutation and chromosome alterations,as well as FAB subgroups,and to analyze the mutation type.MethodsA total of 99 de novo AML patients from 2004 to 2010 in China-Japan Friendship Hospital were studied.Genomic DNA was amplified by polymerase chain reaction (PCR),denaturing polyacrylamide gel electrophoresis (PAGE) and capillary electrophoresis were used to detect the mutation of NPM1 gene in 99 AML patients,and karyotyping was performed in 72 AML patients by G banding techniques.DNA sequences analysis of NPM1 mutation was performed on 10 patients.Chi-square test was used to compare the frequencies of NPM1 mutation among the different subgroups,and McNemar's test was used to compare the different rates between denaturing PAGE and capillary electrophoresis.ResultsThe frequencies of NPM1 mutations were detected in 15％ (15/99) of AML patients with capillary electrophoresis and 11％ (11/99 ) with denaturing PAGE(x2 =2.25,P ＞0.05 ).The NPM1 was at different rates in M2(27％,8/30),M5(32％,6/19),M6( 13％,1/8),respectively (x2 =1.06,P ＞ 0.05 ),and not detected in the other subgroups.NPM1 mutation in patients with normal karyotype(26％ ) was more prevalent than patients with abnormal karyotype (4％) (x2 =5.61,P ＜ 0.05)All of the 10 patients were of A type ( c.860_863dupTCTG).The C-terminal portion of the NPM protein by replacing the last seven amino acids(WQWRKSL) with 11 residues (CLAVEEVSLRK).Two intronic deletions were novel,one case was IVS10-18_-15delCTTT,the other was IVS10-17_-15delTTT.Conclusions NPM1 mutations represents a common genetic abnormality in AML patients,and NPM1 mutation in patients with normal karyotype is higher than patients with abnormal karyotype.Two new intronic deletion mutations are identified.

OBJECTIVE: To investigate the effects of arsenic trioxide (ATO) on the expressions of vascular endothelial growth factor (VEGF) and P-glycoprotein (P-gp) in K562/A02 cells and to explore the correlation between VEGF and P-gp. METHODS: The inhibition rate of K562/A02 cell proliferation was detected by using methyl thiazolyl tetrazolium assay (MTT); the level of VEGF was detected by enzyme-linked immunosorbent assay (ELISA) and the expression rate of P-gp was determined by flow cytometry (FCM). RESULTS: 0.05 micromol/L ATO had no influences on the cell proliferation and the expression of VEGF in K562/A02 cells; 0.4 and 3.2 micromol/L ATO could significantly inhibit the K562/A02 cell proliferation and down-regulate the expression of VEGF in K562/A02 cells (P<0.05). The expression of P-gp did not changed after being exposed to 0.05 and 0.4 micromol/L ATO for 24, 48 and 72 hours (P>0.05). 3.2 micromol/L ATO could remarkably reduce the expression of P-gp in K562/A02 cells after 48- and 72-hour incubation with ATO (P<0.05). CONCLUSIONS: The down-regulation of P-gp and VEGF after being exposed to ATO probably contributes to the reversion of multidrug resistance in K562/A02 cells. The level of VEGF may be related to the expression rate of P-gp in K562/A02 cells.
