CX-conjugated antigen(BSA-CX) were produced by methods of EDC.The spleen cells of BALB/C mouse immunized by BSA-CX were fused with SP2/0 plasmacytoma cells using PEG4000,and selected cultured with HAT and HT medium.A hybridoma cell line of 2H8-B1-F4 was secreened for specificity to CX,and cloned by limited dilution method for 3 times,which secrete high affinity and stable monoclonal antibodies against CX with indirect ELISA. The antibody was characterized by IgG1 isotype, the titers of antibody in cell supernatant and ascites were 1∶1000 and 1∶4?10~5,respectively.The mAb against CX was selective toward dicloxacillin, oxacillin with cross-reactivity of about 19.6% and 21.3%,which can be used to detect CX residues by competitive ELISA.

AIM: To observe clinical efficacy of Tanreqing Injection (Radix Scutellariae, Bear gall powder, Ram's horn, Flos lonicerae japonicae and Fructus forsythiae) in treatment of patients with acute attack of bronchial asthma. METHODS: One hundred and seven patients with an acute asthma were randomly assigned into two groups: a treatment group (n=52, treated by Tanreqing Injection for 10 d in addition to the routine medications) and a control group (n=55, treated by routine medications). The serum levels of ET and TNF-α were determined by radioimmunoassay before and after treatment, respectively. RESULTS: Before treatment, there were no significant differences in the content of serum ET and TNF-α between the treatment group and the control group. However, after 10 d of treatment, the levels of ET and TNF-α inthe treatment group were significantly lower than those of the control group (P<0.01), and clinical efficacy of the treatment group was superior to the control group. CONCLUSION: Inhibitionof ET and TNF-α secretion and intervention inflammatory response might be one of mechanisms of Tanreqing Injection in treatment for acute asthma.

Objective Through the investigation and analysis to "Chinese Medical Digest" and its relative periodicals to get a general idea of the survival and situation of these periodicals and to establish the pattern for their survival and development. Methods Such methods as telephone consultation, questionnaire survey, interview, and conference discussion were adopted to collect the relative information of medical digest periodicals and thus an analysis was made upon it. Results There were 18 kinds of "Chinese Medical Digest" periodicals originally. Of all these 18 kinds of the periodicals, 6 kinds are still publishing, 10 kinds have transferred its nature to first-hand literature periodical, and 2 kinds have ceased their publishment. Conclusion As a result of the computer, the network and the full text database development, the survival of medical digest periodicals are endangered. However, regarding to the different domain of subject, different reforming measures should be taken.

OBJECTIVE:To investigate the effect and cost of Multidimensional iron oral liquid and Polysaccharide iron com-plex capsules in the treatment of iron deficiency anemia during pregnancy. METHODS:By retrospective study,80 cases of iron de-ficiency anemia during pregnancy were divided into control group and trial group in accordance to different therapy plans,with 40 cases in each group. Control group was given Multidimensional iron oral liquid orally,10 ml each time,bid,after breakfast and supper,for consecutive 4 weeks;trial group was given Polysaccharide iron complex capsules orally,0.30 g each time,qd,for con-secutive 4 weeks. Clinical efficacy,erythrocyte related lab indexes,satisfactory rate and ADR were compared between 2 groups, and cost-effectiveness analysis was adopted for economic evaluation. RESULTS:The total effective rate of experimental group was 95.0%,which was higher than 85.0% of control group,but without statistical significance(P>0.05);hemoglobin level,erythro-cyte count and average volume of erythrocyte of trial group were significantly higher or more than control group,and satisfactory rate(95.0% vs. 65.0%)were significantly higher than control group,with statistical significance(P<0.05);no obvious ADR was found in 2 groups. Total cost of trial group and control group were 243.60 and 166.32 yuan,and cost-effective ratio was 2.56 and 1.96;incremental cost-effective ratio was 7.73. Results of sensitivity analysis were same to the result. CONCLUSIONS:Both Multi-dimensional iron oral liquid and Polysaccharide iron complex capsules can improve anemia in patients with iron deficiency anemia during pregnancy. Polysaccharide iron complex capsules show better therapeutic efficacy and satisfactory rate,but it is relatively ex-pensive. Drugs should be selected according to economic situation.
