Objective To compare the effectiveness and safety of raltitrexed and fluorouracil(FU)/leucovorin (LV) combined with oxaliplatin for advanced colorectal cancer. Methods Fifty patients with advanced colorectal cancer diagnosed by histopathology or cytology were randomly divided into two groups with 25 cases each by envelope, but 1 case lost. Patients in experimental group were treated with raltitrexed (3 mg/m2, ≥ 15 min intravenously) combined with oxaliplatin (130 mg/m2 on day 1 ), patients in control group were treated with FU/LV combined with oxaliplatin:LV 100 mg/m2 infusion (over 2 h, from day 1 to day 3 ) followed by FU (400 mg/m2 infusion in 2 h and 600 mg/m2 continuous infusion from day 1 to day 3 ),combined with oxaliplatin ( 130 mg/m2 on day 1 ), 3 weeks were as one cycle. Patients received 6 or less cycles until disease progressed or toxicity could not be tolerated. Results Effective rate was 37.50%(9/24)and 33.33%(8/24) in experimental group and control group respectively (P＞ 0.05). Disease control rate in experimental group was 83.33% (20/24) while in control group was 70.83% ( 17/24 ) (P ＞ 0.05 ). The median time of progression-free survival (PFS) in experimental group and control group was 11.0 months and 9.0 months respectively (95%CI 8.643-11.357,P =0.015). Main adverse effects were anorexia, vomiting, neutropenia, thrombopenia, anemia, neurotoxicity, fatigue, aminotransferase abnormality, and so on. There was no statistic difference between two groups in side effects(P ＞ 0.05). Conclusions Raltitrexed combined with oxaliplatin is an effective regimen for the advanced colorectal cancer. Compared with traditional FU-based regimen, it is more convenient. Patients will have less venous exposure time and hospital days.Effective rate and mean survival time are superior or not inferior in raltitrexed treatment to that of FU-based regimen. Raltitrexed combined with oxaliplatin is worthy to be recommended in treating colorectal cancer.

Endostatin is a potent, endogenous inhibitor of angiogenesis, which corresponds to the C-terminal fragment of collagen ⅩⅧ. The human endostatin gene was amplified from a human fetal liver cDNA library by means of PCR and was cloned into pPIC9K vector. Soluble endostatin was superexpressed in Pichia pastoris (50.5mg/L) . The recombinant protein was purified by cation exchange chromatography with the final yield of more than 95%. Western blotting analysis showed positive immunoreactivity to the expressed product. Recombinant endostatin was able to suppress the angiogenesis on the CAMs. Also, the endostatin inhibited specifically of the migration of HMECs stimulated by bFGF, with EC50 being about 0.4 ?g/ml.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

Objective:To explore the relation of social adaptability to theory of mind (Tom)and executive function (EF)in Chinese children with autism.Method:Thirty-eight children aged 6.0 -12.9 years and meeting the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV)criteria for autism were re-cruited.They were assessed with the Children's Adaptive Behavior Rating Scale,Chinese Wechsler Intelligence Scale for Children (C-WISC),Tom test and EF task,then their adaptive quotient (ADQ),intelligence quotient, scores of theory of mind and executive function were obtained.Results:In this sample,the ADQ was (85.4 ± 20.9),the T scores of independent factor,cognitive factor and social self-control factor were separately (40.2 ± 17.3),(43.3 ±15.7)and (42.0 ±16.0).The median total intelligence quotient was (102.1 ±24.0).After con-trolling for age and intelligence quotient,the score of first false belief understanding was positively correlated with social responsibility subsclale score and social self-control factor score (r =0.50,0.45,Ps <0.05).In executive function test,scores of immediate and delayed recall for details of Rey complex figure recall task were negatively correlated with social responsibility subscale score (r =-0.46,-0.47,Ps <0.05).In Stroop tests,the second test time,the forth test time,the forth test error number and alpha numeric connection error number were negatively cor-related with economic activity subscale score (r =-0.63,-0.57,-0.45,-0.57,Ps <0.05).The second test time of Stroop was negatively correlated with the scores of individual choose subscale and social self-control factor (r =-0.46,-0.50,Ps <0.05).Conclusion:It suggests that social adaptability may be related to theory of mind and executive function.The autistic children with better theory of mind and executive function have better social a-daptability.

Objective To explore a new high-throughput method with internal standards for analyzing the methylation profiles of lung cancer related genes. Methods The promoter sequences of 7 lung cancer related genes were cloned into plasmids and the target segments were amplified by their special primers respectively. The products were treated with M. Sss Ⅰ methylase and bisulfite. The multiplex ligation PCR method was established by designing probes containing CpGpCpG(for methylatedsequence) at the 3' ends and choosing the optimal ligation enzyme, annealing and ligation temperatures. The standard calibrators and clinic samples were tested by fluid chip platform. The results were validated by methylationspecific PCR. Results We successfully set up the standard calibrators for methylation and unmethylaiton of 7 lung cancer related genes and established a multiplex ligation PCR combined with fluid chip method, which was used to detect methylation status of 7 genes simultaneously. The fluorescence value of p16INK4A, APC,DAPK, RARIβ, RASSF1 A, MGMT and GSTP1 methylation standard calibrators were 863,909,703,701,901,1 060 and 885, much higher than that of unmethylation standard calibrators. The results were consistent with the results of methylation-specific PCP. ConclusionThe new high-throughput method can be used to evaluate the methylation status of 7 lung cancer related genes simultaneously and might be useful for clinical practice.

HER2, a member of epidermal growth factor receptor family proteins, is overexpressed in about 30% of human breast cancer. Increased levels of HER2 are associated with poor patient prognosis and enhanced metastasis. RNA interference (RNAi) is developed recently as a new technique which can inhibit gene expression specifically in mammalian cells. On the basis of previous study,in which two target sequences with favorable RNAi effect on HER2 were identified, a series of dual promoter siRNA-expressing vectors containing two opposing U6 and H1 promoters were constructed. After transfection of HER2-overexpressing SKBR3 breast cancer cells with the siRNA-expressing vectors, downregulation of HER2 was identified quantitatively. Subsequently, the siRNA-expressing cassettes were subcloned into lentiviral vectors by LR recombination reaction and lentivirus was prepared successfully. The results from infection of SKBR3 cells with siRNA-expressing lentivirus demonstrated that lentiviral-mediated RNAi could downregulate HER2 expression efficiently through fluorescent quantitative PCR (FQ-PCR), western blot, and FACS analysis. Furthermore, cell growth was inhibited in cell proliferation assay after treatment with siRNA lentivirus.A new tool for clarifying the function of HER2 in cancer metastasis and developing the gene therapy drug was offered.
