BACKGROUND:Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. METHODS:We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients. RESULTS:Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratio of male to female was 1:1.04, and their average age was 33.8 years. Of the 2867 patients, 76.39％ were between 18 and 40 years old. The incidence of acute poisoning was as high as 11.33％ in January each year. The incidence of poisoning was in a descending order:alcohol poisoning (54.55％), medication poisoning (25.95％), pesticide poisoning (5.65％), and drug poisoning (4.88％). Most (56.44％) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning (P < 0.01). Approximately 69.54％ of the patients were followed up after emergency treatment, 30.39％ were hospitalized, and four patients died. CONCLUSIONS:Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment"can significantly improve the survival rate of patients with acute poisoning.

BACKGROUND: With mechanical ventilation widely used in intensive care unit, the ventilator associated pneumonia (VAP) has become a common and serious complication in critically ill patients. Compared with adults, the incidence of VAP and the mortality are higher in children in pediatric intensive care unit (PICU) because of immune deficiency, severe basic diseases, and increased use of artificial airway or mechanical ventilation. Hence it is of significance to study the epidemiology and changes of antibacterial susceptibility in order to reduce the incidence and mortality of VAP in children. METHODS: From January 2008 to June 2010, 2758 children were treated in PICU of Wuhan Children's Hospital. Among them, 171 received mechanical ventilation over 48 hours in PICU, and 46 developed VAP. The distribution and drug-resistance pattern of the pathogenic bacteria isolated from lower respiratory tract aspirations were analyzed. RESULTS: A total of 119 pathogenic microbial strains were isolated. Gram-negative bacilli (G-) were the most (65.55％), followed by fungi (21.01％) and gram-positive cocci (G+, 13.45％). Among them, the most common pathogens were Acinetobacter baummannii, Escherichia coli, Klebsiella pneumoniae, candida albicans and coagulase-negative staphylococci. Antibiotic susceptibility tests indicated that the multiple drug-resistances of G- and G+ to antibiotics were serious. Most of G- was sensitive to ciprofloxacin, amikacin, imipenem, meropenem, cefoperazone-sulbactam and piperacillin-tazobactam. The susceptibility of G+ to vancomycin, teicoplanin and linezolid were 100％. Fungi were almost sensitive to all the antifungal agents. The primary pathogens of VAP were G-, and their multiple drug-resistances were serious. CONCLUSION: In clinical practice we should choose the most sensitive drug for VAP according to pathogenic test.

BACKGROUND: With beta-lactam drugs and immunosuppressants widely used, the infection caused byAcinetobacter baumannii (Ab) has become more and more serious with multidrug resistant Acinetobacter baumannii (MDRAb) emerging and worsening rapidly. Compared with other patients, the incidence and multidrug resistance of MDRAb are higher in children in pediatric intensive care unit (PICU) because of immune deficiency, severe basic diseases, prolonged hospitalization and invasive operations. Hence it is significant to study the epidemiology and changes of antibacterial susceptibility in order to reduce the incidence of MDRAb in children. METHODS: A total 115 patients with MDRAb pneumonia and 45 patients with negative MDRAb (NMDRAb) pneumonia who had been treated from January 2009 to August 2011 were studied retrospectively at the PICU of Wuhan Children's Hospital. Clinical data were analyzed with univariate and multivariate Logistic regression. RESULTS: In 176 clinical strains ofAcinetobacter baumannii isolated, there were 128 strains of MDRAb, accounting for 72.73％. Drug susceptibility tests showed that the resistance rates of β-lactam antibiotics were more than 70％ except for cefoperazone sulbactam. The rates to carbapenems were higher than 90％. They were significantly higher than those of NMDRAb. Amikacin, levofloxacin, ciprofloxacin and minocycline had the lowest drug-resistance rates (<20％). Multivariate Logistic regression revealed that ICU stay, the time of mechanical ventilation, anemia, hypoproteinemia and the use of carbapenems were independent risk factors for MDRAb pneumonia. CONCLUSIONS: MDRAb is an important opportunistic pathogen to pneumonia in PICU, and its drug-resistance is severe. It increases significantly the mortality of patients. It is important to take the effective prevention measures for controlling it.

Objective　To evaluate the effect of Naogongfude (NGFD, a traditional Chinese medicine orally administrated) on learning and memory and the expressions of synaptophysin (SY) and Tau-protein in cerebral cortex and hippocampus in aged rats and to explore the possible mechanism. Methods　Rats were divided into normal and neural disturbance groups according to the outcomes of active avoidance reaction (AAR) test, and then each group was randomly divided into control and NGFD-treated experimental groups. Animals were orally fed with NGFD for 2 months (5 ml/d) in experimental group or routinely fed in control and taken AAR and passive avoidance reaction (PAR) tests. After the rats were sacrificed, the synaptosome count, the expression of SY and Tau-protein, and the neuron apoptosis in cerebrum were examined. Results　The rats after 2-month NGFD administration had an increased AAR acquisition, obviously delayed AAR extinction and prolonged step through latency (STL) of PAR. The number of synaptosomes was raised and the immunoreactive intensity of synaptophysin was increased remarkedly, while Tau-protein immunoreactivity and apoptotic cells were decreased in cerebrum. Conclusion　NGFD does have the effect of improving brain function and putting off the aging of rat brain according to the results of behavior study and morphological observation.
