Hot!
LI Yanping,QIAO Pu,LU Tingting,et al
【Objective】 To investigate the target monitoring and risk factors of nosocomial infection in ICU, and to put forward the preventive measures specifically to control nosocomial infection. 【Methods】 1,289 patients in ICU admitted to the hospital from 1st January 2013 to 31st December 2013 were chosen to calculate the average severity of illness (ASIS), the adjusted incidence of nosocomial infection, the invasive operation related infections and other relevant indicators. High risk factors for infection were analyzed . 【Results】 ICU patients with nosocomial infection covered 66 cases (5.12%), the daily incidence of infection rate was1.036% . After adjustment the infection rate was 1.98‰. The quarterly hospital infection showed a downward trend. The average severity of illness was 2.58, and the incidence of nosocomial infection was 1.98% after adjustment of the severity of the disease,;The most common infections were those related invasive operation : ventilator associated with pneumonia, vascular catheter related bloodstream infection , and catheter related urinary tract infection. The pathogens were mainly gram negative bacteria, with a total of 183 strains (90.59%),and gram positive bacteria took 19 (9.41%). 【Conclusion】 The infection rate of ICU was so high mainly because of 3 kinds of invasive operation related infections; Dynamic changes in ICU infection information can timely be accurated through the access of target monitoring so as to develop interventions to reduce the incidence of nosocomial infection in ICU.

Hot!
LI Dongmei,ZHANG Hongyan,ZHANG Lixin,et al
【Objective】The aim of this study was to investigate the change of aquaporin4(AQP4)after treatment edaravone and mannitol in ischemic brain edema rats.【Methods】150 adult male Wistar rats were randomly divided into randomized to six groups:normal, false surgery, surgery, mannitol(M ), edaravone(E), and edaravone combined with mannitol(E with M).Modified Longa rat brain infarction model (middle cerebral artery occlusion) were applied. The morphological changes of ischemic brain and AQP4 mRNA expression were detected after surgery of middle cerebral artery occlusion and measured treatment at 6h, 1d, 3d, 5d and 7d after each treatment。【Results】Within the ischemic brain, the intercellular space and perivascular space became larger, some neurons showed necrosis phenotype, and the edema was most obvious at 3d and was relieved at 7d. After the treatment with mannitol, the edema was not alleviated and few neurons were seen. In the groups of E and E with M, the cerebral edema was alleviated and more neurons were found seen. After the cerebral infarction, the expression of AQP4 mRNA increased, peaked at 3d, then decreased and returned to almost normal almostly at 7d(P<0.05). AQP4 mRNA of group M was expressed less at the beginning first time, but then increased rapidly(P<0.05) .The expression of AQP4 in the group E and E with M remained low P<0.05).【Conclusion】AQP4 plays an important role in the formation of ischemic cerebral edema. The expression of AQP4 mRNA increased after the cerebral infarction increased. Through the treatment of edaravone combined with mannitol, the expression of AQP4 mRNA decreased and the brain edema was alleviated.

Hot!
XIANG Lanhua,TAN Xiaoping
【Objective】The purpose of this study is to examine the expression of the neutrophil surface adhesion molecule lymphocyte function associated antigen 1(LFA1) and its relationship with preeclampsia disease (PE) patients. 【Methods】Between June 2012 and June 2014, 50 patients with PE were selected as subjects for a research project. These patients were divided into two groups in accordance with their specific medical condition: the severe PE group (20 cases), and the mild PE group (30 cases). During the duration of the experiment, 40 healthy pregnant women were selected as normal control group. The mother's blood and the blood in the umbilical cord were both found to contain neutrophils and neutrophil surface adhesion molecules FLA1 expression. Correlation analysis wasconducted. 【Results】The neutrophil count and neutrophil surfaceadhesion molecule LFA1 positive rate in the blood of the PE group mothers was found to be higher than the control group, with the difference being quite statistically significant (P<0.05). It was also found that as the PE illness aggravated, both the maternal bloodneutrophil count and neutrophil surfaceadhesion molecule LFA1 positive rate showed an increasing trend (P<0.05). In addition, maternal blood neutrophil count, neutrophil surface adhesion molecules LFA1 positive rate in the gestational diabetes group were higher than that of group without gestational diabetes, and the difference was statistically significant (P<0.05); In another analysis of the PE group , the umbilical cord blood neutrophil count and neutrophil surface adhesion molecules LFA1 positive rate were also higher than the control group, with the difference being statistically significant once again (P<0.05), and as the PE illness aggravated, both umbilical cord blood neutrophil count as well as neutrophil surface adhesion molecules LFA1 positive rate showed a trend of increased (P<0.05); Mother blood neutrophils surface expression of adhesion molecules LFA1 positive rate showed a trend of increased positively correlated with systolic blood pressure in patients with PE (r=0.597,P=0.597). Results showed that a mother's bloodneutrophil surface expression of adhesion molecules (LFA1) positive rate directly correlated with the systolic blood pressure in patients with PE (r=0.597,P=0.597), the diastolic blood pressure also showed a direct correlation (r= 0.526,P=0.526). 【Conclusion】Excessive neutrophil activation in patients with PEas well as excessive neutrophil activation is associated with PE severity. From our findings, we can now inhibit the excessive activation of neutrophils in PE pregnancy cases in complications such as prevention and control.
