    2018, 15(2): 65-69. 
    Abstract ( 708 )   PDF (757KB) ( 289 )  
    Objective To study the long-term toxicity of oral administration of different extracts of Epimedium brevicornu Maxim in mice and provide a safety reference for its clinical application. Methods 144 ICR mice were randomly divided into blank control group, high, medium and low dose groups of Epimedium brevicornu Maxim water extract and Epimedium brevicornu Maxim alcohol extract (80, 40, 20 g?kg-1). Continuous gavaging for 8 weeks, the general condition of the mice was observed during the administration, and the body weight was weighed weekly. After the last administration, relevant blood biochemical indexes, system autopsy and histopathological examination were performed. Results Four weeks after continuous administration of Epimedium brevicornu Maxim water extract and ethanol extract, the body weight of female and male mice were significantly lower than the control group(P <0.001). In addition, compared with the control group, the organ coefficient, blood indicators, serum biochemical indicators of Epimedium brevicornu Maxim water extract and ethanol extract groups had a certain degree of change(P <0.05).

    CAI Pei, XIAO Zuo-qi, PAN Tao, OU-YANGBo
    2018, 15(2): 70-72. 
    Abstract ( 347 )   PDF (825KB) ( 196 )  
    Objective To study the effects of Lx2-32c on the proliferation and apoptosis of cervical cell Hela. Methods After treated with different concentration of Lx2-32c for 24, 48, 72 h, the proliferation of cervical cell Hela was determined by MTT. Simultaneously, the apoptosis ratio of Hela by Annexin V-FITC/PI and the expression of Bcl-2 and cleaved-caspase-3 by western blotting were detected. Results Lx2-32c could effectively inhibit the proliferation of Hela in a dose-dependent and time-dependent manner. At the same time, Lx2-32c induced apoptosis and down-regulated the expression of Bcl-2 and up-regulated the expression of cleaved-caspase-3 in Hela. Conclusion Lx2-32c maybe induced apoptosis and inhibited the proliferation of Hela involving in mitochondrial pathway.

    Abstract ( 402 )   PDF (1015KB) ( 174 )  
    Objective To describe the clinical utilization of ribavirin in Ningbo city, Yinzhou District. Methods We conducted a descriptive analysis of the clinical utilization of ribavirin in 3 general hospitals and 24 community health centers from 2010 to 2016 by using Yinzhou healthcare information database. Results During the study period, we found 1587 504 outpatients' prescriptions of ribavirin and 673,661 ribavirin users. Ribavirin injections accounted for 97.74% of all ribavirin prescriptions. In addition, ribavirin was mainly prescribed by primary grade medical institutions. The result showed the number of prescriptions and users of ribavirin was decreasing. Moreover, ribavirin prescriptions of children (≤14) accounted for 50.56% of the total number of ribavirin prescriptions. Among all ribavirin prescriptions, there were 68.85% recorded diagnosis of acute upper respiratory tract infection. Conclusion The results indicated that there were large amount of irrational prescriptions of ribavirin. Clinicians should adhere to the indication of ribavirin injection and pay attention to the treatment.

    ZHANG Xiao-meng, LIN Zhi-jian, ZHANG Bing, LI Min
    2018, 15(2): 103-109. 
    Abstract ( 321 )   PDF (1093KB) ( 169 )  
    Objective Quantitatively comparing the benefit and risk of Aconitum and Tripterygium in the treatment of axial spondyloarthritis (ax-SpA), which can provide guidance for rational use of medicines in clinic. Methods The data, which from random clinical trials (RCTs) that Aconitum or Tripterygium vernus western medicines in the treatment of ax-SpA, was extracted and merged by RevMan 5.2 software. Based on the benefit-risk assessment framework of herbs for treating ax-SpA that was built by the multi-criteria decision analysis model in Hiview 3 software, the benefit value, the risk value and the total benefit-risk value of Aconitum and Tripterygium were calculated. And the probability of difference value caused by the two therapies were conducted by Monte Carlo simulation. Results 14 RCTs of Aconitum and 7 RCTs of Tripterygium that each vernus western medicines in the treatment of ax-SpA were included. Comprehensively and quantitatively compared the benefit and risk of Aconitum and Tripterygium in the treatment of ax-SpA, the difference of efficacy between Aconitum and Tripterygium was 3[95%CI (7.39, 16.45)], which probability was 86.53%; and the difference of risk was 80[95%CI (73.24,86.48)], which probability was 100%. When benefit and risk were the same important for ax-SpA patients, the total benefit-risk value of using Aconitum was 65, while that of Tripterygium was 24, their difference was 41[95%CI(35.67,46.23)] and the probability of the former superior to the latter was 100%. The results were stable which tested by sensitivity analysis. Conclusion Based on the available evidence, the benefit-risk of Aconitum for ax-SpA patients is significantly superior to that of Tripterygium. If ax-SpA patients that cannot accept the medication risk, the application of Tripterygium is not recommended.

    Comparative Analysis of Adverse Drug Reactions Caused by Iodixanol and Iohexol
    XU Zhi-xiang
    2018, 15(2): 125-128. 
    Abstract ( 481 )   PDF (663KB) ( 399 )  
    Objective To investigate the characteristics of adverse drug reactions (ADRs) caused by iodixanol and iohexol in order to provide reference for safe drug use in clinical practice. Methods Reports of ADR caused by iodixanol and iohexol were selected from database of Hangzhou Drug and Medical Devices Adverse Reaction Monitoring Center from January 2013 to April 2017 and divided into two groups. Patients' information, major manifestations, proportion of serious ADR, proportion of delayed ADR and latent time of ADR were compared. Statistical methods such as statistical tables, statistical graphs, chi-square test, t-test, survival analysis and Breslow test were used to deal with the data. Results A total of 228 reports were entered, including 73 cases caused by iodixanol and 155 cases caused by iohexol. Mean age of iodixanol group was older than iohexol group (P<0.05). There was no statistically significant difference (P=0.69) in proportion of serious ADR between the two groups: 6.85% for iodixanol vs. 8.39% for iohexol. Proportion of delayed ADR of iodixanol group (69.86%) was higher than iohexol group (7.10%) (P<0.01). Average latent time of iodixanol group was longer than iohexol group (P<0.01). Conclusion Iodixanol and iohexol have some different clinical manifestations in ADR, iodixanol had higher proportion of delayed ADR and longer latent time, so maybe it's necessary to prolong medical observation time properly after administration of iodixanol.
