RESUMO
Objective Evaluation of the efficacy and safety of intravenous(IV)combined with intrathecal/intraventricular injection(ITH/IVT)of polymyxin against intracranial infection with multidrug-resistant bacteria.Methods The databases,including Wanfang,VIP,Chinese Biomedical Literature,Pubmed,Embase,ScienceDirect,and Cochrane Library were searched,case-control studies on IV+ITH/IVT polymyxin against intracranial infection with multidrug-resistant bacteria by January 2023 were screen.RevMan 5.4 software was used for meta-analysis.Results A total of 9 retrospective studies were included.The fatality rate in IV+ITH/IVT polymyxin group was significantly lower than that in IV group(OR =0.19,95%CI:0.11-0.35,P<0.01).There was no significant difference in ICU hospitalization days(OR =-2.32,95%CI:-23.59-18.89,P =0.83)and adverse reaction rate(OR =0.93,95%CI:0.26-3.38,P =0.91)between IV+ITH/IVT group and IV group.Conclusion IV+ITH/IVT polymyxin in treating the intracranial infection with multidrug-resistant bacteria can significantly reduce fatality rate,and does not significantly increase adverse reactions.
RESUMO
In order to investigate the possibility that oxytocin (OT) is involved in stress reaction, the effect of OT or antioxytocin serum (AOTS) on rat swimming maintaining time was observed. On intraventrncularly administrating 0.625, 1.25, 2.5 and 5.0ng OT 5min before swimming,the swimming maintaining time was 29.32?5.84%, 44.92?4.54%. 60.18?4.21% and 80.48?3.62% shorter than that before injection,respectively.All the swimming maintaining time of the experimental groups was shorter significantly than that of the control group which was intraventricularly injected saline (p
