ABSTRACT
Objective To study the clinical effect of serum calcitonin in the treatment of pediatric respiratory tract infections.Methods A retrospective analysis of our hospital in the patient's medical records from April 2015 to April 2016 were 80 cases of pediatric respiratory tract infection, were randomly divided into control group and observation group, 40 cases of respiratory tract infection were treated with standard antibiotic therapy in the control group, the observation group was treated with antibiotics in the treatment of serum calcitonin under the guidance of the comparative analysis of two groups of children with clinical efficacy, clinical symptoms disappear time, antibiotic use and hospital economy.Results The effective rate of control group was 70%, and the observation group was 90%.The clinical efficiency of the observation group was relatively higher than control group ( P <0.05).Compared with the control group, the clinical symptoms of the patients in the observation group were significantly lower than that of the control group(P<0.05).Patients in the observation group used antibiotics was 16 cases(40%), the antibiotic use rate was, 32 cases(80%) in the control group, the average usage time of antibiotics and the average cost of observation group was significantly lower than control group(P<0.05)..The time of hospitalization and the hospitalization expenses of,observation group were lower than control group(P<0.05).Conclusion The treatment of pediatric respiratory infection in serum calcitonin can help improve the clinical efficacy, reduce the use of antibiotics in children with high economic.
ABSTRACT
Objective To investigate the effect of focal cerebral ischemic preconditioning (IPC) on brain edema and the expression of nuclear factor-?B( NF-?B) and its target gene MMP-9. Methods Forty-five SD rats were divided into 3 groups in which control group received sham surgery only, and the other two groups received 2 hours of middle cerebral artery occlusion (MCAO) followed by 22 hours of reperfusion with or without 10 minutes of IPC 3 days before. Brain water content, expression of NF-?B and MMP-9 mRNA were evaluated in each group by wet-dry weight method, immunohistochemistry staining and RT-PCR. Results Compared with the SS group, there was a lower NF-?B immunoreactivity and MMP-9 mRNA level (16 098.2?1 265.3 vs 23 565.8?1 978.4,50.7% vs 84.1%, P
