Objective:To compare amony ceftriazone, penicillin, and ciprofluxacin in the treatment of lower respiratory tract infection. 　Methods:Cost-effectiveness was comparitively analysed by using the principle of pharmacoeconomics with ceftriazone, penicillin, and ciprofluxacin in the treatment of lower respiratory tract infection. 　Results:Three drugs in the treatment of lower respiratory trace infection, while cost of penicillin was the lowest.　Conclusion:Penicillin is a first selective drugs for lower respiratory tract infection.

Objective To observe the clinical efficacy of fire-needle therapy in treating scapulohumeral periarthritis, and to observe the changes of pain score and the motor function of shoulder joint. Method Totally 180 patients were randomized into a fire-needle therapy group of 90 cases and a filiform needle group of 90 cases by randomized single-blinded method. Result There were significant differences between the two groups in comparing the recovery rate, motor function of shoulder joint, and the relapse rate 30 d after the whole intervention (P<0.01), while there were no significant differences in Visual Analogue Scale (VAS) score and total effective rate (P>0.05). Conclusion Compared to filiform needle therapy, fire-needle therapy can produce a better recovery rate and motor function of shoulder joint in treating scapulohumeral periarthritis.
