OBJECTIVE: To evaluate the use of Xingnaojing Injection in medical insurance inpatients in Beijing city so as to provide reference for rational drug use and medical insurance billing.METHODS: Inpatient cases using Xingnaojing Injection in 5 Beijing hospitals of different levels were randomly sampled from the 2004 Beijing Medical Insurance Database,and analyzed in terms of indication, dosage, treatment course and ADR.RESULTS: A total of 676 cases were sampled with more than 25 kinds of indications,and among the top 10 indications, 18.0% were inconsistent with the instruction,and 17.5% were in lack of evidence support such as randomized controlled trials.Individual dose of Xingnaojing Injection was(27.9?9.0)mL, which was higher than the usual dose described by the instructions and clinical trials.The mean treatment course of Xingnaojing Injeciton was 14.6 days,with 20.9% exceeding 20 days.Drugs used in combination with Xingnaojing Injection included anti - thrombosis agents( 13.3% ) and traditional Chinese medicines with the action of promoting blood circulation and removing blood stasis (12.7%) .CONCLUSION: The use of Xingnaojing injection in medical insurance patients was not consistant with the instruction or evidence supported by clinical trials.

Objective: To compare the pharmacokinetic c haracteristics of amphoterici n B liposomes injection (LAmB) with market amphotericin B injection (MAmB) in ra bbits by intravenous administration. Methods: LAmB and MAmB wer e intravenously ad ministrated to rabbits at a single dosage of 1 mg*kg －1. The AmB concent rations i n plasma samples were determined by HPLC, and the pharmacokinetic parameters wer e calculated by means of 3P97, and ANOVA were done by means of the Excel softwar e. Results: The concentration- time data of LAmB and MAmB after intravenous administration were best fitted acc ording to three compartment-model with a weight of 1/C and 1 respectively . After a singl e intravenous administra tion, C max　of LAmB and MAmB were 8.4±2.1 and 2.4±0.6 mg*L －1, AUC were 22.5±6.8 and 9.0±1.9 mg*h*L －1, CL were 0.050±0 .024 and 0.114 ±0.022 L*h －1, V c were 0.13±0.04 and 0.46±0.18 L , respectively. Comparing with MAmB, all rabbits showed high plasma levels, large area under the curve values and low cl earance, small apparent volume of distribution of LAmB. Conclusion: There were several striking differences between the pharmacokinetics properties of LAmB and MAmB in jection in rabbits. All changes of the pharmacokinetics properties will be advan tageous to reduce toxicity and improve therapeutic effect.

OBJECTIVE:To promote rational use of Xingnaojing (XNJ) injection in medical insurance patients.METHODS:Clinical trials on indications of XNJ were searched systematically,and clinical evidence that XNJ was applied for different indications were collected and classified.A questionnaire survey was carried out in 20 medical institutions to find out the doctors' attitude and prescribing practice relating to indications,application indications,usage and dosage,timing of application and drug combination of XNJ.The results of above 2 kinds of studies were provided to a group of experts to reach consensus about guideline of XNJ.RESULTS:Guidelines of XNJ,which contained the application indications,timing of medication,dosage,treatment course and drug combination,were developed.The strength and degree of evidence were labeled for each items of recommendation.CONCLUSION:For drugs with low-quality clinical evidence,guideline should be developed according to experts' consensus which is based on evidence-based medicine.

Objective To demonstrate the possibility when discriminating between severe and nonsevere tricuspid regurgitation by E-wave velocity in tricuspid flow.Methods The peak velocity of the tricuspid inflow E-wave was measured in 107 patients,who were divided into mild group(n =39),moderate group(n =42)and severe group(n =26)according to the degree of tricuspid regurgitation(TR).Results Peak E-wave velocity of mild group,moderate group and severe group was (48.6 ±13.8)cm/s,(47.4 ±11.7)cm/s,and (78.3 ±26.1)cm/s, respectively.Mean E-wave velocity of mild group and moderate group were similar,which were lower than that of severe group (P <0.01).A peak E-wave velocity of over 62 cm/s had a sensitivity of 71% and specificity of 92% for the detection of severe TR.Conclusion Increased peak tricuspid E-wave velocity is associated with severe TR and thus can be used as a simple measure of TR grade.

Objective To investigate the effects of ulinastatin pretreatment on oxidative stress response and hepatocyte growth factor (HGF) after hepatectomy in rats.Methods One hundred and twelve pathogen-free male Sprague-Dawley rats,aged 3 months,weighing 230-280 g,were randomly divided into 2 groups (n=56 each): group hepatectomy (group H) and group ulinastatin pretreatment (group U).Left and median lobe resection was performed and then liver ischemia was induced by blood flow occlusion of right and caudate lobes for 30 min,followed by perfusion in both groups.Ulinastatin 50 000 U/kg was injected intravenously at 5 min before occlusion in group U.Eight rats in each group were chosen and the blood samples were taken from the inferior vena cava for measurement of serum ALT and AST activities and HGF concentration before ischemia and at 1,6,12,24and 48 h of reperfusion.Then the right lobe were removed for determination of apoptosis,SOD and myeloperoxidase (MPO) activities,MDA content,expression of proliferating cell nuclear antigen (PCNA) and liver regeneration.Apoptotic index was calculated.Another 8 rats in each group were chosen and the 7 day survival rate was recorded.Results Compared with group H,the levels of ALT,AST,MPO aud MDA and apoptotic index were significantly decreased,and the levels of HGF and SOD,PCNA expression and liver regeneration were significantly increased at different time points in group U (P ＜ 0.05).There was no significant difference in 7 day survival rate between group H and group U (P＞ 0.05).Conclusion Ulinastatin pretreatment can strengthen liver regeneration after hepatectomy in rats,the underlying mechanism may be related to inhibition of oxidative stress response and increase in HGF production.

After selecting the literature and extracting the data ，the quality of RCT was evaluated by modified Jadad scale ，and the quality of cohort st udy was evaluated by NOS scale. Network Meta-analysis was performed by using Stata 16.0 software. RESULTS ：A total of 29 literatures were included ，involving 15 RCTs and 14 cohort studies. A total of 3 112 patients and 12 therapeutic regimens were involved ，including twice IVIG ，twice IVIG+hormone，twice IVIG+ulinastatin ，first IVIG ，first time IVIG+hormone ，first time IVIG+cyclosporine ，first time IVIG+ etanercept，hormone，hormone+ulinastatin，ulinastatin，infliximab and placebo. The results of network Meta-analysis showed that in terms of the incidence of coronary artery injury （CAL），twice IVIG+hormone was significant lower than hormone ，and first time IVIG +etanercept was significant lower than first time IVIG （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of CAL incidence in ascending order was hormone ＜ulinastatin＜twice IVIG ＜first time IVIG＜first IVIG+hormone ＜twice IVIG+hormone ＜infliximab＜first time IVIG+cyclosporin ＜first time IVIG+etanercept. In terms of the incidence of ADR ，compared with twice IVIG+ hormone and hormone ，twice IVIG and first time IVIG+etanercept were decreased significantly ；infliximab was significantly lower than hormone （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of ADR incidence in ascending order was hormone ＜twice IVIG+hormone ＜first time IVIG+hormone ＜first time IVIG+cyclosporin ＜first time IVIG ＜twice IVIG ＜first time IVIG+etanercept ＜infliximab. In terms of the serum level of CRP ，compared with twice IVIG ，twice IVIG+hormone ，twice IVIG+ulinastatin and hormone were decreased significantly；twice IVIG+hormone was significantly lower than first time IVIG ；twice IVIG+ulinastatin were all significantly lower than twice IVIG+hormone ，hormone，hormone+ulinastatin，first time IVIG ，first time IVIG+hormone and ulinastatin （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of serum CRP level in ascending order was first time IVIG ＜first time IVIG+hormone ＜twice IVIG ＜hormone+ulinastatin＜ulinastatin＜infliximab＜hormone＜twice IVIG+hormone＜twice IVIG+ulinastatin. In terms of improving persistent fever duration ，there was no statistical difference between pairwise treatment measures （P＞0.05）. The sorting results of network Meta-analysis showed area under cumulative ranking curve of persistent fever time in ascending order was first time IVIG ＜placebo＜first time IVIG+cyclosporine ＜hormone＜twice IVIG+ hormone＜twice IVIG ＜ulinastatin＜infamliximab. CONCLUSIONS ：The first time IVIG+etanercept has the best effect in reducing the incidence of CAL. Infliximab possesses a relatively low incidence of ADR and the best antipyretic effect. Twice IVIG + ulinastatin has the best anti-inflammatory effect.
