Dynamic renal imaging studies were performed in 132 patients using 99m Tc DTPA and 131 I OIH. Effective renal plasma flow(ERPF) and glomerular filtration rate(GFR) was obtained. GFRs were calculated with 2 background regions of interest(ROI),conventional subrenal areas(SB) and suprarenal areas(SP). The relative renal functions(RR) obtained by GFRs determination was significantly higer compared with that by ERPF. These results suggested that the RR of impaired kidney determined by GFR(SB) was obviously higher than that assessed by ERPF. Higher coefficient( r value) was gotten with GFR(SP) than with GFR(SB).Results suggested that the GFR obtained with conventional subrenal background ROI might overestimate individual renal function of the poorly functional kidney and the GFR estimated by suprarenal background ROI might be more accurate.

Objective To explore the image quality and radiation dose for coronary angiography using DSCT (dual-source computed tomography) under lower tube voltage and lower contrast agent concentration ('double low').Methods A total of 160 patients with suspected coronary artery disease underwent dual-source CCTA.80 patients (BMI ＜ 25 kg/m2) were randomly assigned to group A (270 mg I/ml-80 kV) and B (350 mg I/ml-120 kV).The other 80 patients (25 ≤ BMI ＜30 kg/m2) were randomly assigned to group C (270 mg I/ml-100 kV) and D (350 mg I/ml-120 kV),sonogram affirmed iterative reconstruction technology and 270 mg I/ml contrast agent were applied to group A and C ; FBP technology and 350 mg I/ml contrast agent were applied to group B and D.Adaptive cardio-sequence prospective ECG-gated technology was applied in all patients,while the acquisition phase was 65％-75％ RR interval (when heart rate ＜ 75 beats / min) or 40％-50％ RR interval at when heart rate ≥ 75 beats/min.Volume CT dose index (CTDIvol),dose length product (DLP),effective dose (E),size specific dose estimates (SSDE),image noise,CT value,signal-to-noise ratio (SNR),and contrast-to-noise ratio(CNR) were all evaluated for each patient.Results There was not statistical difference in scan length among groups A and B,C and D.There was statistical difference in tube current between group A and B (t =8.932,P ＜0.05).There was not statistical difference in tube current between group C and D (tCD =-1.212,P ＞ 0.05).There was statistical difference in CTDIvol,DLP,E and SSDE between group A and B,C and D (tCTDIvol =-16.141,-11.440 ; tDLP =-17.454,-10.521 ; t =-17.444,-10.523 ;tSSDE =-13.032,-9.119,P ＜0.05).Compared to group B,the SSDE in group A decreased by 64.4％.Compared to group D,the SSDE in group C decreased by 39.3％.There was no statistical difference in image noise between group A and B,C and D (P ＞ 0.05).There was statistical difference in CT value,SNR and CNR between group A and B (t =0.436,4.623,3.272,P ＜ 0.05).There was no statistical difference in CT value and CNR between group C and D,while there was statistical difference in SNR between group C and D (t =2.981,P ＜0.05).There was no statistical difference in image quality scores between group A and B,C and D (P ＞ 0.05).Conclusion Compared with conventional DSCT coronary angiography,'double low' DSCT coronary scanning solution can significantly reduce the radiation dose and contrast agent,and could provide the effective coronary images which meet the clinical diagnostic needs.

Microtubule is one of the key components of the cytoskeleton and plays an important role in the maintenance of cell shape and the process of signal transduction and mitosis. Due to the extreme importance of microtubule in the process of mitosis, tubulin becomes one of the most important targets for development of new anticancer drugs and tubulin inhibitors are used for the treatment of cancer nowadays. These inhibitors have antitumor activity by inhibiting or promoting the assembly of tubulin to microtubules and interfering the process of cell mitosis. This review summarized the research progress of the tubulin inhibitors, especially the introduction of the tubulin inhibitors of pharmacological activities and the progress of clinical research. Also, the development trend of these inhibitors is discussed.

Objective:To evaluate the clinical application of vancomycin in a cancer hospital in order to promote the rational use of vancomycin. Methods:The records of 66 patients treated with vancomycin in 2015 were reviewed and analyzed in the respects of in-dications of medication, pathogenic examination, usage and dosage, course of treatment, drug combination, drug monitoring and drug utilization index(DUI). Results:Among the 66 cases, most drug use was rational, which accounted for 69. 70% with DUI of 0. 82. There were still several types of irrational drug use including no medication indications, irrational usage and dosage, too long or too short course of treatment, irrational combination and prophylactic use time. Conclusion:The application of vancomycin is basically ra-tional, while irrational phenomenon still exists. The management and supervision should be further strengthened in order to promote clinical rational drug use and ensure medication safety of patients.

Objective To assess the reliability and validity of summary of diabetes self-care activities for type 2 diabetes patients in China.Methods We selected 80 patients with type 2 diabetes to carry out our investigation and chose 10 of them to retest 2 weeks later.Results The general Cronbach's α was 0.62 with a reliability coefficient of 0.83(P<0.01).We got 8 factors with an accumulation contribution of 0.92 by main-ingredient and variance analysis.The factor loading was more than 0.80. Conclusion The Chinese version of SDSCA had good reliability and validity to evaluate the self-care activities of type 2 diabetes patients.

Objective To investigate the change of CD8+T lymphocyte non-cytotoxic antivirus response(CNAR)in slow progressors infected by HIV.Methods Applying with density gradient and immunomagnetic beads methods to purify the CD4+T lymphocyte from the healthy person and CD8+T lymphocyte from HIV-infected individuals.The CD4+T cell was infected by HIV(SF-33)virus and cocuhured with CD8+T cell.The culture supernatant was collected and the p24 value was detected by ELISA method.Results Our study showed that the CNAR function decreased by turns of slow progressors(SP),typical progressors(TP),health control group and AIDS group.There was significant difference between groups(P<0.01).We found a significant positive correlation between the CIM+T cell ture count and the CNAR function.The virus load didn't statistically correlate with the CNAR function.Conclusion The CNAR function possibly protected the HIV-infected individuals from progression.

Objective:To establish an HPLC method for the determination of paclitaxel and docetaxel in plasma to provide refer-ence for the individualized treatment regimen and the evaluation of curative effect and adverse reactions. Methods:Paclitaxel and do-cetaxel were used as the internal standard for each other. The samples were precipitated by acetonitrile and separated on a DikMA Dia-monsil C18 column with a mixture of acetonitrile-water (55: 45) as the mobile phase. The flow rate was 1. 2 ml·min-1 . The column temperature was set at 25℃. Paclitaxel and docetaxel were detected by UV-detection (λ= 227 nm). Results: A linearity was ob-tained within the range of 0. 078-10. 0 mg·L-1 for paclitaxel and docetaxel. The limit of quantitation was 0. 039 mg·L-1 . The aver-age recovery of paclitaxel and docetaxel was 99. 85% and 100. 35%, respectively. The inter- and intra-day RSD were both less than 5% and the RSD for freeze-thaw stability was below 10%. The plasma concentration of paclitaxel in clinical samples was within the range of 0. 18-6. 16 mg·L-1 and obvious individual difference was shown. Conclusion:Therapeutic drug monitoring is very important due to the obvious differences in plasma concentration of paclitaxel and docetaxel. The established method is sensitive, accurate, con-venient and rapid in r the therapeutic drug monitoring, and is useful for the adverse drug reactions monitoring and pharmacokinetic study.
