Objective To research the pathogenies' types and analyze the antibacterial drug' s using rationality from the children with acute respiratory infection,our study were generated by pediatric department from the hospital lasting 2 years.Methods A total of 93 pediatric patients with acute respiratory infection admitted from December 1,2010 through November 30,2012 were enrolled into study.The throat swabs from 93 patients were sent to the Beijing Center for Disease and Prevention (CDC) to identify the influenza virus,syncytial virus and mycoplasma with rapid nucleic acid test.The specimens of sputum from hospitalized patients were sent to the hospital bacterial laboratory for bacteria culture.With the Children Drug Utilization Index (cDUI),the rationality of using antibiotics was estimated.The database was established by using SPSS version 18.0 software and the data were analyzed to determine the statistical distinction among the percentage by the Chi square test (P ＜ 0.05).Results Of them,70.96％ pediatric patients were below 3 years old (excluding newborns).Of them,62.36％ patients had positive findings of viral infection.The predominant viruses of respiratory infection were syncytial virus accounting for 30.43％,the influenza viruses 24.63％ and the para-influenza virus 10.14％.The patients with positive results in vital test were more vulnerable to lower respiratory infection than those with negative results.The pneumonia patients with positive finding of syncytial virus accounted for 85.71％ (18 patients) in which the median cDUI was 1.30.The antibiotics were given to 28 pneumonia patients with positive virus test,in which the median cDUI was 1.05.Of 28 pneumonia patients,4 (16％) had positive bacteria growth in sputum cultures,and 4 cases (16％) had positive bacteria growth in blood cultures.Conclusions In the district of hospital,the lower respiratory infection was usually caused by viruses.Therefore,antibiotics should not be given in patients without evidence of bacterial infection.It is a irrational strategy to use antibiotics in those patients when the Children Drug Utilization Index is high (＞ 1.0).It is paramount important to notice that the percentage of positive bacteria growth in sputum cultures is usually not high because the antibiotics are given by OPD physicians before hospitalization of patients with bacterial infections in the acute respiratory illness.

BACKGROUND: Experiments have demonstrated that exogenous basic fibroblast growth factor (bFGF) promotes the growth and survival of skeletal muscle satellite cells, and endogenous bFGF also has obvious effect on muscular repair.But whether bFGF gene transfection has the same effect on extraocular muscle satellite cells is unclear.OBJECTIVE: The goal of this study was to investigate the effect of bFGF gene transfection on the bio-behavior of rat extraocular muscle satellite cells.DESIGN: Single sample observation.SETTING: Department of Ophthalmology, Qingdao University Medical College.MATERIALS: Primary rat extraocular muscle satellite cells were cultured (purity ＞ 90%). Human PEGFP-N3-bFGF eukaryotic expression vector was successfully constructed (reported in other papers).METHODS: This study was carried out in the Central Laboratory of Qingdao University Medical College between September 2005 and December 2006. Experimental intervention and grouping: During the experiment, 3 groups were divided: Experimental group, in which, recombinant PEGFP-N3-bFGF was used for transfection; Control group A, in which, empty-load PEGFP-N3 was used for transfection; Control group B: in which, only F 10 medium (0.1 volume fraction of fetal bovine serum)was used for transfection. Recombinant PEGFP-N3-bFGF plasmid was used to transfect rat extraocular muscle satellite cells cultured in vitro by liposome-mediated transgenic technology. Experimental evaluation: bFGF expression was observed by immubohistochemical method; Transfection efficiency was detected with fluorescence microscope; The protein secretion of bFGF of satellite cells in each group was detected by SBC-ELISA method on the 1st, 3rd, 5th, 9th, 11th, 13th, 15th, 21st and 28th days of culture; The proliferation of rat extraocular muscle satellite cells in each group was detected by methyl thiazolyl tetrazolium(MTT) method; Creatine kinase (CK) activity of cells in each group was determined according to the A value of some standard whose concentration was known.MAIN OUTCOME MEASURES: ① Transfection efficiency of bFGF gene to rat extraocular muscle satellite cells cultured in vitro and bFGF gene expression after transfection; ②bFGF protein secretion after transfection, and effect of bFGF gene transfection on the growth and proliferation of extraocular muscle satellite cells.RESULTS: ① Transfection efficiency of bFGF gene to rat extraocular muscle satellite cells cultured in vitrowas (42.8±1.2)%. ② Immunohistochemical detection showed positive reaction. ②Transfected cells could secrete bFGF protein,which was the highest on the 5th day (662.935 ng/L). ④ The proliferation activity of transfected cells was obviously enhanced, and its A value was significantly higher than that of control group at the same time point (P ＜ 0.05). ⑤CK value was higher than that of the control group from the 5th day after transfection to the end (P ＜ 0.01).CONCLUSION: bFGF gene transfering into rat extraocular muscle satellite cells can make extraocular muscle satellite cells to secrete bFGF, promote cell proliferation, survival and differentiation.
