Tumor may generate from tumor stem cell and the microenvironment,and cancer stem cells are derived from the mutation of normal stem cells according to cancer stem cells hypothesis. Breast cancer stem cells are the first identified cancer stem cells in solid tumor. Breast cancer stem cells have been isolated successfully by many kinds of strategies, and their biological behaviors are gradually studied deeply. Self-renewal and differentiation of breast cancer stem cells are regulated by microenviroment and many signaling pathways. Therapy targeting breast cancer stem cells is gradually becoming the focus of tumor targeted therapy study.

Objective To compare the effects of early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor.Methods The clinical data of 32 patients with normuscle invasive bladder cancer were retrospectively analyzed.They were divided into observation group (16 cases) and control group (16 cases).The clinical effects of the two groups were compared.Results The recurrence rate of two groups was significantly different (x2 =3.864,P ＜ 0.05).The average recurrence time of two groups was significantly different (t =6.389,P ＜ 0.05).The incidence rate of adverse reactions (x2 =0.369,P ＞ 0.05) and the incidence rate of toxic reactions(x2 =2.222,P ＞ 0.05) in two groups had no statistically significant differences.Conclusion It can lower the recurrence rate for early and conventional instillation of normuscle invasive bladder cancer after transurethral resection of bladder tumor and to delay the recurrence time,so it is widely applicable for clinic cure.

Objective:To investigate the problems and countermeasures primary hospital radiology digital construction.Methods: The analysis of the current characteristics of the primary hospital radiology digital construction of its problems, propose solutions.Results:The primary hospital exists in the construction of digital radiology department layout as unscientific, CR and DR choose unreasonable, machine design flaws, PACS incompatible, system maintenance improper and operation of the medical staff is not standardized, require planning, the management, design, training, etc. to further improve.Conclusion: Radiology digital construction is the inevitable trend of development, only reasonable choice, scientific installation, meticulously maintained, proficient in primary hospital and give full play to its advantages.

Objective:To investigate the therapeutic medication for inpatients with cancer pain, and compare with the latest cancer treatment guidelines to improve the rational drug use. Methods:By a retrospective study, the medical record analysis for the inpatients with cancer from October to December in 2014 was performed, and the incidence of pain and the therapeutic medication were investiga-ted and the rationality of drug use was evaluated based on the latest cancer pain treatment guidelines. Results:The incidence of cancer pain was 25. 46% of 774 cases with new cancer, and 76. 58% of the patients with cancer pain were treated with analgesic drugs. In ac-cordance with the guidelines for the treatment scheme, there was no significant difference between the Opioid-Naive group ( guide group 1) and the Opioids-Tolerant group (guide group 2) in the combination therapy, while there was significant difference in the drug selec-tion and the time of administration. In the guide group 1 the proportion of oxywdone controlled-release tablets was signiticantly higher than that in the guide group 2, the ratio of taking the medicine on time in the guide group 1 was also higher than that in the guide group 2. Both groups showed difference from the guidelines in the pain assessment and titration and specific analgesic drug use. Conclusion:The findings indicate the difference between the pain treatment and the guidelines in therapeutic medication of cancer pain, and the propaganda and education of relevant knowledge should be strengthened to promote the treatment standard.

OBJECTIVE:To investigate the status quo of the use of Chinese patent medicines in our hospital and to put forward the coping strategies.METHODS:The data about the consumption of Chinese patent medicines in our hospital during the period of 2002～2006 obtained from medical information platform were analyzed in respect of consumption sum,DDDs,and DDC using the method of DDDs sequence and the method in pharmacoeconomics.RESULTS:The use of Chinese patent medicines in our hospital during 2002～2006 took on an obvious rising trend.CONCLUSION:The utilization of Chinese patent medicines in our hospital is rational basically.The Chinese patent medicines with suitable prices and proved efficacy take a great share in the clinical application.However,there are still some problems remain to be standardized.

OBJECTIVE:To investigate the distribution of magnetic nanoparticle embedding Paclitaxel in vivo and its curative effect on lung cancer in mice model.METHODS:The magnetic lipsomes containing Paclitaxel and the Paclitaxel liposomes were injected into caudal vein of mice,and which were exposed to magnetic field of 0.5T.The concentrations of the two drugs in different organs were determined.The lung cancer model was established in mice and the therapeutic efficacy of the different drugs on tumor was evaluated by comparing the weight of mice before and after administration.RESULTS: In the mice treated with magnetic liposome containing Paclitaxel,the drug concentration in lung which was exposed to magnetic field was significantly higher than that in the others sites,and a steady state concentration was reached quickly in lung after administration,but gradually in other organs.In the mice treated with liposomes containing paclitaxel,a steady state concentration was reached gradually in lung.The tumor control rate was 27.53% in mice treated with magnetic liposome containing Paclitaxel plus magnetic field intervention,significantly higher than in the control group.CONCLUSION: The result shows that magnetic targeting drug delivery is an effective drug delivery system,by which,the drugs can aggregate to the target site in large quantity which may lead to a reduced distribution of drugs in non-target sites.

Identification and determination of hyoscine in Zhichuanling Injection were carried out by TLC. It was suggested that TLC-colorimetry could be sued to determine hyoscine content. The method showed a good separation,high specificity,but lower requirement for apparatus.

AIM: To establish an analytical method for detecting 14 kinds of amino acid in Wuling Capsule(xylaria) by HPLC-FLD. METHODS: After being derivated in precolumn with o-phthalaldehyde and ?-mercaptoethanol,the amino acids were eluted by gradient elution and were detected with a fluorescence detector (Ex = 340 nm,Em = 450 nm). The mobile phase consisted of 0. 1 mol/L NaH2PO4 ( adjusted to pH 6. 8 by phosphoric acid) and methanol with a flow rate of 1. 0 mL/min,column temperature was set at 30 ℃. RESULTS: The deriva-tives of 14 amino acids with o-phthalaldehyde could be separated with a stable base line within 40 min. The linear range of the detection was 5-200 nmol/mL and correlation coefficients were over 0. 999 0. CONCLUSION: The method is simple,accurate and well reproduced for the determination of amino acids in Wuling Capsule.

Objective To investigate the role and feasibility of tumor necrosis factor(TNF) and/or interferon(IFN) in comprehensive treatment of tongue cancer in vitro and explore a new pathway about clinical treatment of tongue cancer . Methods The role of TNF and/or IFN in tongue cancer cell line (Tca 8113) growth and their effect on chemotherapy & radiotherapy of Tca8113 were detected by MTT-assay in vitro.Results ⑴There was a obvious volume-effect relationship in inhibitory effect of TNF or IFN on tongue cancer cell line; when TNF combind with IFN,their cytotoxity enhanced significantly than only TNF or IFN. ⑵TNF & IFN have enhanced the cytotoxities of low dose DDP,PLM and Taxol on Tca 8113 cell line.⑶TNF obviously enhanced the inhibition rate of radiotherapy(dosage:2～8Gy)on Tac 8113 cell line(P
