1.Applications of proteomics in the research of tumors
Journal of International Oncology 2013;(5):335-338
Proteomics is an emerging discipline which studies the composition of proteins and their transformation rules at the cellular level and the overall level.Recently,proteomics has been used in a variety of studies of tumors.And it has made some progresses in explaining the mechanisms of tumors' genesis and development,discovering new specific markers for tumors and new targets for drug treatment,and forecasting tumors' biological behaviors.

Objective The purpose of this study is to evaluate the effects of intensified cyclic training on bone moulding reconstruction, and to found the scientific basis of intensific cyclic training as a new training methods. Methods 48 male rats were equally divided into two groups: intensive repetitive training group and control group. The upper segment of tibia was harvested from the animals at the 1st, 2nd, 3rd, 4th, 5th and 6th week after the onset of the experiment for the measurement of cortical thickness (CT), mean wall thickness (MWT) and the percentage of osseous surface of trabeculae and surface area of trabecular Absorption (Sr). The data of intensive repetitive trained group were compared with those of the control group. 1 303 recruits were divided into control group and experimental group. In the experimental group, they were trained by intensive repetitive training program instead of the traditional training program. The incidence of stress fracture was compared between two groups. Results CT (1.37?0.09, 1.86?0.14, 1.94?0.23), MWT (56.37?2.52, 57.28?3.01, 58.23?2.93) and Sos (12.29?1.17, 14.61?1.84, 15.51?1.13) were higher in the training group than control groups at the fourth week, the fifth week and the sixth week, respectively (P

Objective To survey the prevalence of the pulmonary function test in Liaoning province and investigate the cognition of chronic obstructive pulmonary disease(COPD)patients to the test.Methods One hundred and twenty nine comprehensive hospitals of Grade Three and Grade Two have been included to survey the prevalence of the pulmonary function test by telephone.A cross-sectional study was carried out among 206 COPD outpatients to investigate their cognition to the pulmonary function test.Results The total prevalence of the hospitals with the equipment and ability to do pulmonary function tests was only 51.2%.The prevalence of the hospitals of Grade Three(79.4%)was higher than that of the hospitals of Grade Two(24.2%).In 206 COPD patients,100 cases(48.5%)had been provided with pulmonary function test,53 cases(25.73%)had been diagnosed as COPD in the past.The patients diagnosed as COPD accounted for 33.8% of all chronic bronchitis patients surveyed.The span during the diagnosis of chronic bronchitis and the definitive diagnosis of COPD was 11.79±10.96 years.Conclusion The prevalence of pulmonary function test in Liaoning province is relatively low,especially in the comprehensive hospitals of Grade Two.Few chronic bronchitis patients received pulmonary function test.Thus the time span from the diagnosis of chronic bronchitis to definitive diagnosis of COPD is long as well.

BACKGROUND: Monoamine hypothesis has been demonstrated by researches. However, the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression has less been reported.OBJECTIVE: To study the effect of different drugs on metabolite of plaama monoamine neurotransmitter, and the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression.DESIGN: Case controlled study.SETTING: Neurological Department and Brain Institute of Nanjing Medical University.PARTICIPANTS: Forty patients with depression hospitalized in Nanjing Brain Hospital (depression group) were diagnosed with the second revised edition of China classification of mental diseases(CCMD-2) and the tenth edition of International classification of diseases. And the total score of Hanmilton rating scale for depression(HAMD) was more than 17. Healthy voluntary blood donators in the control group were from Nanjing Municipal Central Blood Station( n = 20).INTERVENTIONS: Antidepressant was used in the depression for 4 weeks: fluoxetine 20 mg per day; 5-serotonin selective reuptake inhibitor (SSRI) paroxetine 20 mg per day; venlafaxime 50- 100 mg per day;5-serotonin and morepinephrine selective reuptake inhibitor(SNRI) fluvoxamine 50-100 mg per day. High performance liquid chromatograpy(HPLC)was used to measure the level of metabolite of plasma monoamine neurotransmitter in patients with depression before and 42 week after treatment, and the HAMD was used to evaluate clinical effect of the patients.MAIN OUTCOME MEASURES: The levels of metabolites of plasma monoamine neurotransmitters in patients with depression: 5-hydroxyindoleace tic acid(5-HIAA), 3-methoxy-4-hydroxyphenylglycol(MHPG) and homovani llic acid(HVA) were measured before and 4th week after treatment.RESULTS: The levels of 5-HIAA, MHPG and HVA of the metabolites of plasma monoamine neurotransmitters in patients with depression before treatment [ (20.3±14.6), (124.8±103.6), (54.7±32.1) μg/L] were all lower than those in the normal control group[ (39.5±28.4), (334.5 ±107.3), (88.5±37.2) μg/L], with statistically significant differences (P<0.05). After SSRI treatment, the 5-HIAA content[ (37.1±21.9)μg/L]was significantly increased as compared with that before treatment, whose difference indicated significant meaning ( P<0.05), but the differences in MHPG and HVA had no significant meaning as compared with those before treatment(P>0.05) . After SNRI treatment, 5-HIAA and MHPG contents [(35.4±25.2 ), (291.2±120.4) μg/L] both were significantly increased, which indicated significant difference as compared with those before treatment( P<0.05); but HVA level had no significant changes.CONCLUSION:'The peripheral neurotransmitter metabolites in plasma can reflect their states in brain. The change of neurotransmitter metabolite in plasma can be regarded as an important reference index for the evaluation of depression.

The research of interleukin-13 receptor ?2(IL-13R?2) chain is a rising pop these years.Previous studies have shown that many human tumors overexpress IL-13R?2 chain,while normal cells do not express this receptor or express very low level.This difference of express level is significant to diagnose and cure tumors by the IL-13R?2-directed toxin fusion protein.During the past decade,the structure and the function of IL-13R?2 together with the relationship between this receptor and tumors has been further developed.Therefore new therapies and theories can be proposed as the clinical tumor treatments.In this case,the expression in various tumor cell lines was not only focused on but also on the IL-13 and toxin fusion protein killing effect in both the cell level and the in vivo level.Besides,an overview of the mechanism in the treatment of IL-13R?2-directed toxin fusion protein together with the improved methods for fusion protein purification and other relative tumor therapy was given.In conclusion,the current status and progress of IL-13R?2 as well as IL-13R?2-directed toxin fusion protein in tumor therapy were represented.

Objective:To establish a real time dissolution determination method for furosemide tablets and compare the similarity of dissolution curves of furosemide tablets from 11 generic drug manufacturers and the original research drug manufacturer in four kinds of dissolution media to evaluate the overall situation of dissolution process of furosemide tablets in our country. Methods:A fiber-optic medicine dissolution process real time test system was used to monitor the dissolution process of furosemide tablets from 11 generic drug manufacturers and the original research drug manufacturer. A paddle method was applied and the rotation speed was 50 r·min-1 . The dissolution medium was pH 1. 2 hydrochloric acid solution, pH 4. 0 acetate buffer, pH 6. 8 phosphate buffer and water, respectively with volume of 900 ml. The absorbance wavelength was 277 nm. The dissolution profile was drawn and f 2 factor was used to evaluate the similarity. Results:The dissolution tests were not influenced by the excipients and the dissolution media. The liner range of furose-mide was 4. 44-26. 66 μg·ml-1(r=0. 9997). The average recovery of furosemide was 101. 26% and RSD was 1. 84%(n=9). Ee-spect to 11 manufactures, there was only one of the dissolution similarity can meet the requirements. Conclusion:A simple, fast and accurate fiber-optic method for medicine dissolution process real time test is established. The method can reflect the real dissolution and provide the information on how to improve the preparation technology and monitor the stability of the preparation technology.
