Objective To determine the content of astragaloside Ⅳin Qi Zao Granules.Methods Equipped with the evaporative light scattering detector (ELSD), a RP-HPLC method was established. The chromatographic column was C18 and the column temperature was at 30 ℃.The drift tube temperature was at 40 ℃and the evaporative gas was nitrogen with pressure of 3.5 bar.The mobile phase was acetonitrile-water(30∶70) and the flow rate was 1mL/min. Results This method showed a good linear relationship in the range of 2.51～50.2 ?g astragaloside Ⅳ. The average recovery was 98.13 %with RSD being 1.28 %. Conclusion The method is sensitive and accurate and can be used for the quality control of Qi Zao Granules.

Objective To investigate the role of thrombelastography(TEG) in assessing the risk of bleeding and diagnostic value in patients with acute leukemia(AL) .Methods The TEG and PLT data were counted in 127 patients(272 sets of data) who were diagnosed with AL .Those patients were divided into two groups :group 1 (including patients with bleeding) and group 2 (in‐cluding patients with no bleeding) .The indicators(R values ,K values ,α‐angle ,MA values)and PLT count were compared between two groups .Those data with PLT<30 × 109/L of these two groups also were divided and the 4 indicators of TEG were compared between the two groups .We used the ROC curve to evaluate the sensitivity and specificity in assessing the risk of bleeding .Results According to the data in total ,the K value ,R value of the group 1 were higher than those of the group 2(P<0 .05);theα‐angle and MA value ,PLT counts of group 1 were lower than those of the group 2(P<0 .05) .In those AL patients whose PLT<30 × 109/L ,the K value of the group 1 was higher than that of the group 2(P<0 .05);theα‐Angle and MA value of the group 1 were lower than those of the group 2(P<0 .05);R values and PLT count were not different between the two groups(P>0 .05);the are‐as under the ROC curve about the PLT counts ,MA value andα‐angle were more than 0 .5 (0 .750 ,0 .740 and 0 .653) .Conclusion T EG could predict the risk of bleeding in acute leukemia patients and it could be used in clinical application .

OBJECTIVE:To discuss ward drug control to ensure safe.METHODS:We analyzed retrospectively the application of 5S theory in ward drug control.RESULTS & CONCLUSION:By this drug control mode,drugs were classified according to varieties,usage,frequency of use etc,drug control quality and work efficiency were enhanced,patients' needs could be satisfies and staff' s professional quality was enhanced.

Erectile dysfunction(ED) is a common ailment in middle-aged and old men. Since tadalafil was introduced into the treatment of ED in October, 2002, more and more ED patients have chosen tadalafil due to its efficacy and safety. The action mechanism, pharmacokinetics, efficacy and safety of tadalafil have been reported in many basic and clinical research documents. This review is to address the safety of tadalafil in treating ED, and provide further guidance for clinicians' choice and safer use of the drug.

Objective To study the geographical distribution of the HIV/AIDS epidemic in C city .Methods Based on the theory of multiple regression analysis ,trend surface regression mathematical model was constructed .The latitude and longitude coordinates of different districts and data of HIV/AIDS were collected in the model and the results by ArcGIS software were got ,the trend sur-face analysis chart was drawed at last .Results HIV/AIDS infection rates trend surface regression mathematical model of C city was statistically significant difference(P< 0 .05) ,its goodness-of-fit was 53 .18% .Regions exsisted abnormal residual value and should be the paid attention to explore protective or risk factors in these regions .Conclusion The method can be used in the analy-sis of C city HIV/AIDS epidemic systematic variation in the geographic distribution and local district ,and provide some clues for the local epidemic prevention and controlling of HIV/AIDS .

Objective To establish a quantitative analysis of multi-components by single-marker (QAMS) for determination of four components (adenosine, uridine, guanosine, (R, S)-goitrin) in Isatidis Radix granules.Method The QAMS for Isatidis Radix granules was established and validated and adenosine was selected as the internal reference substance.The relative correction factor (RCF) of other three components were calculated.The contents of four components were determined by both external standard method and QAMS.The QAMS method was validated through comparison of the results obtained by the two different methods.Results The RCFs of uridine, guanosine and (R, S)-goitrin all showed good reproducibility within certain ranges.For Isatidis Radix granules, uridine, guanosine and (R, S)-goitrin, there was no significant difference between the quantitative results of the two methods.Conclusions The QAMS method is simple, feasible and credible to be used for comprehensive quality control of Isatidis Radix granules.
