Objective To investigate and evaluate the preparation of quality control serum of autoantibodies threshold . Methods Donors′ serum blood were placed in 56 ℃ for 30 min to inactivate ,followed by centrifuged to remove the precipitates ,and then multi-batch quality control material in detection kit were detected in dilution ratios of 1∶2 ,1∶4 ,1∶6 .Results Anti-RNP/Sm antibody(+ + + ):after 1∶2 dilution ,the coloration degree was + + + ;after 1∶4 ,1∶6 dilution ,the coloration degree was ++ .Anti-SS-A antibody(+ + to + + + ):after 1∶2 dilution ,the coloration degree was + + ;after 1∶4 ,1∶6 dilution ,the colora-tion degree was + to + + .Anti-RO-52 antibody(+ + to + + + ):after 1∶2 dilution ,the coloration degree was + to + + ;after 1∶4 ,1∶6 dilution ,the coloration degree was + .Anti-nucleosome antibodies :positive were found in dilution of 1∶1 ,1∶2;after 1∶4 ,1∶6 dilution ,the coloration was negative .Conclusion Preparation of quality control serum of autoantibodies is convenient , reliable ,and can meet the needs of clinical detection of internal quality control .

This study was aimed to evaluate the clinical effect and safety of Qing-Fei Tong-Luo (QFTL) ointment for treating children with pneumonia.Randomized controlled trial (RCT) was conducted among 460 cases of children with pneumonia.The observation group was given QFTL ointment combined with basic treatment.And the control group was only treated by basic treatment.Evaluation was given on the total clinical efficacy,disappeared time of fever,cough,expectoration,shortness of breath,and medication safety.The incidence of respiratory diseases was followed up on the 30th days after drug withdrawal.The results showed that in the aspect of clinical efficacy between two groups,the cure rate of the observation group was 98.26％,and that of the control group was 93.89％,with statistic significance (P ＜ 0.05).The cure rate of the observation group was better than that of the control group.There was statistical difference on expectoration disappeared time (P ＜ 0.05).There was no statistical difference on disappeared time of fever,cough and shortness of breath (P ＞ 0.05).There was statistical difference on the incidence of respiratory diseases on the 30th days followed-up after drug withdrawal (P ＜ 0.05).There was no statistical difference on the incidence of upper respiratory tract infection,pneumonia and asthma (P ＞ 0.05).No adverse reactions occurred in the observation group.It was concluded that QFTL ointment combined with basic therapy on the treatment of pneumonia in children was significantly better than the control group in the aspect of clinical efficacy,expectoration disappeared time and the incidence of bronchitis.It is safe and effective.The prognosis is good and worthy of promotion in the clinical practice.
