Observation of tigecycline administration in gram-negative bacteria infected children with ventilator-associated pneumonia / 中国小儿急救医学

Objective To investigate the efficacy and safety of tigecycline therapy in children with ventilator-associated pneumonia infected by gram-negative bacteria. Methods We conducted a restrospective chart review of children with ventilator-associated pneumonia in a tertiary hospital from May 1,2012 to April 30,2017. Inclusion criteria:positive sputum culture result;receiving tigecycline administration of at least 2 days (4 doses). Clinical data and laboratory results were recorded before and after the therapy. Results Twenty-seven children were enrolled,with the in-hospital mortality of 37. 0％(10/27). Twenty-seven bacteri-a strains were recorded,all of which were gram-negative,with Acinetobacter baumanmii took up the most. Most bacteria were susceptible to tigecycline. Median duration of tigecycline was 10 days ( 3-27 days ) , 40. 7％ patients(11/27) got clinically improvement and 44. 4％(12/27) got pathogen eradication. Sulpera-zone was the most concomitantly used antibiotics. Totally 3 dosage models were observed and model 1(load-ing dose 2 mg/kg,maintain dose 1 mg/kg) and model 2 ( loading dose 1. 5 mg/kg,maintain dose 1 mg/kg) were the primary. Rate of clinical improvement and microbiology eradication in model 1 group was higher than other groups. No serious adverse effect was detected. Conclusion Tigecycline combined with other a-gents could be used as salvage therapy in gram-negative bacteria infected ventilator-associated pneumonia children and it is tolerated.

Essential hypertention and blood cells / 医学研究生学报

This review summarized the current studies about the abnormality of blood cells morphology,transmembrane transport and membrane receptor and the change of Hemodynamies in essential hypertention.It suggests that these alternations play an important role in the pathogenesis of hypertention.

Protection of low-molecular heparin and urokinase on LPS-induced glomerular inflammation in rats / 解放军医学杂志

Objective To investigate the protective effects of low-molecular heparin and urokinase on glomerular inflammation. Methods Forty 3-month-old female Wistar rats were randomly divided into five groups with 8 rats in each group: normal control (NC) group; lipopolysaccharide (LPS) group; LPS and tranexamic acid (LT) group; LPS, tranexamic acid and low-molecular heparin (LTH) group; and LPS, tranexamic acid and urokinase (LTU) group. Fibrin deposition and CD11b positive cells were identified by immunohistochemical staining. Western blotting was used to determine the ICAM-1 expression. Results No fibrin depositions and CD11b positive cells were found in glomeruli of rats in NC group. Compared with NC group, fibrin deposit (9.1%?1.6%), CD11b positive cell (11.2?2.1) and ICAM-1 expressions (0.23?0.09) were significantly increased in L group (P0.05). Conclusion Both low-molecular heparin and urokinase can effectively decrease fibrin deposits and alleviate inflammation.
