Objective To observe the THP for locally advanced breast cancer in recent efficacy and toxicity. Methods 32 patients with locally advanced breast cancer received chemotherapy: THP 50mg/m~2 , intravenous injection; day 1: CTX600mg/m 5 - FU500mg/m~2, ivgtt on day 1 and day 8,for a period of 21 days. Results 73% had efficiency,with small heart poisonous side effects. Conclusion New adjuvant chemotherapy with THP - containing regimen for the treatment of locally advanced breast cancer has a higher efficacy, and adverse reactions can be tolerated.

Objective:To construct a eukaryotic expression vector for wild-type human Interleukin-13(whIL-13)and its mutant(mhIL-13) gene fused with enhanced green fluorescent protein(EGFP) and to analyze the expression and subcellular location of the fusion protein in COS-7 cells.Methods:The whole whIL-13 and mhIL-13 coding gene was amplified by RT-PCR. And then the expression vector for EGFP-whIL-13, EGFP-mhIL-13 fusion protein were constructed.The recombinant fusion gene were transfected into COS-7 cells.The expression and subcellular location of the fusion protein were detected by confocal microscopy.Results:The construction of expression vector were all corrected.In the positive cells, green fluorescent was found to be localized in cytoplasm,while empty in nucleus.Conclusion:The expression vectors for EGFP-whIL-13, EGFP-mhIL-13 fusion protein were constructed successfully and expressed in COS-7 cells. Fusion proteins were distributed in cytoplasm and no significant difference was observed between them.

To reveal the scientific research situation of general hospitals in recent years in　china,the authors retrieved papers included in CBM、CCD and ISI Web of Knowledge,and compared　the production of papers from the general hospital in 15 sub-provincial cities during the period of 2000　-2009.Also the citation frequency of all papers and the average citation frequency were compared.

Objective To establish a scientific evaluation index system for medical service scientific research competitiveness for government assessment.Methods The evaluation indexes and their weights were determined after two rounds Delphi consultation.Results Construct a hierachical index system composed of three groups,namely investment,output and effects,including three first class index,13 second ones and 50 third ones after two rounds Delphi consultation.Conclusions The index system has reasonable structure and comprehensive contents,reflecting the core idea of scientific research competitiveness evaluation.

Service for key subjects is important for medical information institutions nowadays.This paper discusses the necessity of providing subject-oriented service,and proposes three service modes:information transmission mode,information analysis mode and information navigation mode.In addition,the guarantee measures are also discussed,including constructing a security system for subject literature,training high-quality services team,and promoting subject information service brand.

Objective We try to find the current situation of Hangzhou health research.Methods Using established evaluation index system to evaluate 8 medical service.Results Scientific research development level of 8 medical service is unbalanced,but input-output is balance.Conclusions According to the appraisal results,we suggest reduce the gap among the scientific level of medical service,train high-level personnel,strengthen the construction of key discipline and specialties,create the atmosphere of project application,and establish scientific research incentive system.

AIM: To observe the local expression of nuclear factor-?B(NF-?B) in spontaneously hypertensive rat(SHR) kidney and effects of AT1 receptor contagonist valsartan.METHODS: 16 SHRs were randomly divided into two groups: SHR control group and valsartan group.Another 8 WKY rats act as normal control group.Systolic blood pressure(SBP) of SHR was measured at the beginning and the end of 2,4,6 and 8 weeks of intervention treatment.Radioimmunoassay was used to determine the activities of rennin and angiotensin II(AngII).The renal tissue NF-?B protein expression was detected by immunobiochemistry.RESULTS: SBP of SHR was remarkably decreased after valsartan intervention.However,the rennin activities and AngII level in plasma increased in valsartan group.In the renal tissue of SHR,there was remarkably increased in expression of NF-?B protein.Valsartan could significantly reduced NF-?B expression.CONCLUSION: Valsartan can depress NF-?B renal expression in protein level and might benefit hypotension renal function.

Poly(ADP-ribose)polymerase-1 (PARP-1) plays a significant role in the DNA repair process by catalyzing the transfer of ADP-ribose from NAD+ to its receptors. It is a promising anticancer drug target and many PARP-1 inhibitors have been developed and used in the clinical trial. In this work, a series of 3-(2-oxo-2-substituted acetamido)benzamides have been synthesized and their inhibitory activities against PARP-1 were evaluated. Of all the tested compounds, six compounds displayed inhibitory activities with IC50 values ranging from 0.23 to 5.78 µmol.L-1 . The binding pose of compound 5a was predicted using molecular docking to facilitate further structural modification.

Objective To purify recombinant methioninase and investigate the synergetic inhibitory effect of methioninase and cisplatin on the proliferation of human lung adenocarcinoma cell line GLC. Methods Recombinant methioninase was purified with GST-column from supernatant after ultrasonic disruption of cultured Escherichia coli in the prokaryotic expression system pGEX-4T-1-Met/Dh5a. MTT assay was used to determine the inhibition rate of methioninase in combined with cisplatin on cell proliferation,and their synergistic effect was evaluated by using the q value judge method. Results The concentration of recombinant methionine cleaving enzyme was 0.22 mg/mL, the purity was 95%, and the activity was 0.568 IU/mg. After 72 h culturing, the inhibition rate of cisplatin methionine was 24.80%and 27.49%respectively,while the inhibition rate of the combined drugs was 66.80% ( =1.47>1.15) which showed a significant synergistic effect. Conclusion Both methioninase and cisplatin have the inhibition effect,and the combined drugs display a significant synergistic effect on the proliferation of GLC.

Saponin and sapogenin are main components in chinese medicine Anemarrhena asphodeloides Bge.Modern research has shown that Anemarrhena asphodeloides Bge and its effective components could markedly enhance the ability of learning and memory in dementia animals,as well as improve the descent of brain function.The effect was related with many factors such as inhancing the cholinergic receptor(M,N),improving the activity of ChAT and inhibiting the activity of AChE,regulating the balance of ? receptor-cAMP and M receptor-cGMP,improving the metabolite of free radicals in model animal brains and so on.
