OBJECTIVE:To observe the effects of aerosol inhalation of Chuankezhi injection on lung index and tissue morphol-ogy of trachea,lung and esophagus in guinea pigs. METHODS:40 guinea pigs were randomly divided into blank control group (normal saline),Chuankezhi high-dose,medium-dose and low dose (2.48,1.24 and 0.62 ml/kg) groups. Each treatment group was administrated by inhaling the atomized injection,once a day,20 ml/kg,for consecutive 2 weeks. The general situation of guin-ea pigs was observed 1 h after each time of medication;1 h after last medication,lung index of guinea pigs was detected,as well as the tissue morphology of left lung,right lung,trachea and esophagus by HE staining. RESULTS:Compared with normal control group,the general situation of guinea pigs were normal in Chuankezhi high-dose,medium-dose and low dose groups;there was no difference in lung index and all of them were about 0.653;tissue section staining showed that no abnormal lesion was found in these tissues. CONCLUSIONS:2 weeks of aerosol inhalation of Chuankezhi injection have no significant effect on lung index and the tissue morphology of trachea,lung and esophagus of guinea pigs.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:From 2012 to 2014,5 medical records were selected randomly from 17 clinical departments each month,1 005 cases in 2012,1 020 cases each year in 2013 and 2014,a total of 3 045 cases. Rationality of antibiotics use was analyzed to summarize and analyze irrational drug use. RE-SULTS:The rate of antibiotics use from 2012 to 2014 were 39.90%,36.27% and 32.84%;the rational rate of antibiotics medical orders were 40.90%,68.11% and 82.67%. Irrational drug use manifested as irrational medication time,unreasonable drug selec-tion,inappropriate indications,inappropriate drug selection,inappropriate usage and dosage,inappropriate drug combination, off-label use etc. CONCLUSIONS:By clinical pharmacistsadvance interventionandadministrative intervention,the use of an-tibiotics in wards of our hospital tend to be more reasonable. But it still necds to strengthen awareness arnd management to effective-ly protect the rational drug use.

OBJECTIVE To investigate the prevalence,antibiotic resistance and genotype of the extended-spectrum ?-lactamases(ESBLs)-producing clinical isolates of Klebsiella pneumoniae.METHODS A total of 104 isolates of K.pneumoniae were examined for the ESBLs production and the susceptibilities of the bacteria to 15 antimicrobial agents.PCR was performed to detect the genes encoding the ESBLs belonging to SHV and TEM families as well as CTX-M-1 and CTX-M-9 groups.RESULTS The ESBLs-producers of K.pneumoniae were 54.0% in the total of 104 isolates.Almost all of the ESBLs-producing isolates were resistant to the antibiotics commonly used,and only remained susceptible to carbapenems and the combination of cefoperazone with sulbactam.The genes of SHV,CTX-M-1 and TEM groups were detected in the ESBLs-producing isolates by 64.3%,46.4%,and 32.1%,respectively,and 35.7% and 8.9% of ESBLs-producing K.pneumoniae strains carried two and three genes.CONCLUSIONS The clinical isolates of K.pneumoniae in Tianjin Nankai Hospital are shown a high rate of ESBLs-producing and antibiotic resistance.SHV and CTX-M-1 groups of ESBLs are the dominant genotypes in the isolates of ESBLs-producing K.pneumoniae.
