OBJECTIVE:To improve the quality of pharmacist consultation,provide real-time,precise and whole-process medi-cine guidance and to promote rational drug use. METHODS:The functions of electronic pharmacy consultation system(EPCS)in our hospital were introduced,and its effects were evaluated. RESULTS:The system had several modules as multiple dimensional knowledge assistant system,real-time prescription checking engine,electronic consultation record method,pharmacist workload and quality statistical analysis. EPCS provided convenient information access,prescription auditing,consultation record and statisti-cal analysis so as to improve consultation efficiency and accuracy. Compared with before using EPCS,EPCS had enhanced speed of inquiring information by 3.75 times,prescription auditing by 4 times,consultation record by 6 times and statistical analysis by 20 times;return visit rate to potients increased from 0.03% to 0.34%. The number of consulting questions increased month by month. The type of consultation question,the identity of the consultant and others could be classified statistically based on the sys-tem. CONCLUSIONS:EPCS helps pharmacist to build a more scientific and effective consultation platform,and promotes rational drug use in the hospital.

Objective To study the characteristics of susceptibility weighted imaging (SWI) and it's role in glioma classfication. Methods 45 glioma patients with pathologically confirmion, underwent preopera-tive plain MRI, enhanced MRI and SWI examination. By using double blind method, the score of T1 WI, T2WI, enhanced T1 WI, SWI and enhanced SWI were acquired to display enhancing tumor, peritumoral edema, tumor hemorrhage and tumor vein. The tumor volume of low signal areas was measured by using measurement software to acquire the bleeding of tumor. Results In 26 cases of high grade gliomas,18 patients with intratu-moral, multiple patchy low signal cords in varying degrees, which were proved by pathology as tumor hemorrhage and tumor blood vessels; in 19 case of low grade gliomas, 10 cases occured a few spots, linear low signal in tumor, which were proved by pathology as tumor hemorrhage; the bleeding of high grade gliomas was higher than that of the low level group ( P < 0.05 ). SWI was superior to T, WI, T2 WI on displaying tumor hemorrhage and tumor vein(P<0. 05). Conclusion Different grades of glioma show obvious different display on SWI, and SWI probably be helpful for evaluation of glioma grading preoperatively.

The effective components are the material basis for efficacy of Traditional Chinese Medicine (TCM), also the core of its quality control. This paper focused on two key scientific issues that how do the effective components form?, How can we improve the effective components?, combining with examples of our group's research, to dis-cuss the research thoughts, technical methods for TCM quality-design. This paper provided a methodological refer-ence for the study of TCM quality-control.

Objective To study the characteristics of diffusion tensor imaging (DTI) in brain tumor and it's diagnosis and differential diagnosis value.Methods Thirty-nine patients with brain tumors proven by pathologically (10 meningioma,17 glioma,12 metastatic tumors) were enrolled,by using Philips Achieva 1.5 T MRI,conventional MRI and DTI were underwent on them,fractional anisotropy (FA) maps,apparent diffusion coefficient (ADC) maps and three dimensional white matter fiber bundle map were reconstructed in the workstation.The core substance of the tumor area and the contralateral mirror area were selected as the region of interest,and FA and ADC values of them were measured,and t test was performed.Results The FA values of meningioma,metastases tumors and gliomas were 0.36 ± 0.08,0.28 ± 0.03,0.18 ± 0.06,respectively,and the differences among them were significant( P < 0.05).The ADC values of meningioma,metastases tumors and gliomas were 1.72 ± 0.10,1.52 ± 0.22,1.34 ± 0.14,respectively,and the differences among them were significant( P < 0.05).Conclusion DTI has high clinical value in identification of meningiomas,metastatic tumors and glioma.

OBJECTIVE:To study the inhibitory mechanism of timosaponin B-Ⅱ(TB-Ⅱ) on the proliferation and migration of human lung cancer A549 cells. METHODS:A549 cells were treated with TB-Ⅱ [0(blank control),1,10 and 100 μg/ml] for 48 h,and total RNA and total protein were extracted respectively. Real time fluorescence quantitative-PCR and Western blot were used to detect mRNA and protein levels of IL-18. IL-18 in A549 cells was silenced by transfection;the expression of IL-18 mRNA and protein were compared among untransfection group,negative control group and transfection group;and then human lung can-cer A549 cells with silenced gene were treated with 10 μg/ml TB-Ⅱ for 24,48 and 72 h. The activity of cell proliferation was de-tected with CCK-8,and the change of cell migration ability was observed by streak method. RESULTS:Compared with blank con-trol,the expression of IL-18 mRNA and protein in A549 cells all increased after treated with TB-Ⅱ(P<0.05 or P<0.01),and were positively correlated with concentration. Compared with untransfection group,the expression of IL-18 mRNA and protein de-creased in transfection group(P<0.01). Compared with untransfected cell treated with TB-Ⅱ,the viability and migration ability of A549 cells with transfection gene increased after treated with TB-Ⅱ for 72 h(P<0.01). CONCLUSIONS:TB-Ⅱ can inhibit the proliferation and migration of A549 cells by up-regulating IL-18 gene expression.
