Objective To observe the pathogens and drug-resistance of ventilator-associated pneumonia (VAP) patients in emergency intensive care unit (EICU) for rational antibiotic therapy and the prevention of VAP. Method The sputum culture results and drug-resistance of pathogens of VAP patients in EICU from 2007 to 2009 were collected. Results One hundred and two mechanical ventilation patients were selected. VAP was occurred in 70 patients (68.6%). One hundred and fifty-seven pathogens had been examined,including 92 Gram-negative bacilli (58.6%),35 Gram-positive cocci (22.3%) and 30 fungus (19.1%). Pseudomonas aeruginosa and meticillin-resistant-staphylococcus aureus was 22 strains (14.0%)respectively, stenotrop homonas maltophilia was 21 strains (13.4%) and acinetobacter baumanii was 17 strains (10.8%). Fifty-nine patients (84.3%) had suffered from multiple pathogen infection, with 31 cases having 2 pathogens and 28 cases having 3 pathogens. Conclusions Pseudomonas aeruginosaa,methicillinresistant staphylococcus, stenotrophomonas maltophilia and acinetobacter baumanii are main pathogens of VAP in EICU patients,and candida albicans is still the main pathogens in fungal infection. The rate of multiple pathogen infection is very high, and the problem of drug-resistance is very severe.

Methods High frequency sonography was used to examine 37 cases of herpes zoster patients with 77 pathological changes, 7 cases of sequence of neuralgia with 17 pathological changes. Compared with the healthy side of the same patient, thickness and echo feature of the skin and subcutaneous tissue, the width and echo feature of the skin nerves were recorded. Results The skin and subcutaneous tissue of the herpes zoster patients thickened (P 0.05),but the involved skin nerves widened significantly(P

Objective To study the practical value of serum prealbumin and butyrylcholinesterase in Child-Pugh classification of liver cirrhosis. Methods 66 serum samples of patients with liver cirrhosis and 50 serum samples of the healthy subjects were collected for detecting prealbumin (PA) level and butyrylcholinesterase (BuChE) activity, as well as hepatic functional indices(serum albumin, total bilirubin and alanine aminotransferase). The patients were classified according to the Child-Pugh score. Results Compared with healthy subjects, the content of PA and the activity of BuChE significantly decreased in the patients with liver cirrhosis. According to the Child-Pugh classification, PA content and BuChE activity in different grades of liver cirrhosis varied obviously. Conclusion The content of serum PA and the activity of serum BuChE had an important guiding significance in diagnosing the extent of liver cirrhosis, which can serve as effective indices for diagnosis of patients'condition and prognostic evaluation of liver cirrhosis.

Objective To measure the fractional anisotropy(FA) values in the language function areas(Broca area,Wernicke area and arcuate fasciculus)by diffusion tensor imaging(DTI),discussing the pathological characteristics in cerebral palsy children with language development delay.Methods DTI was performed in twenty-seven cerebral palsy children with language development delay(observation group) and 20 children with febrile seizures(control group) by Philips 3.0T MRI scanner.The FA values of Broca area,Wernicke area and arcuate fasciculus were measured at Philips Workstation.Results The FA values of control group in the left Broca area,Wernicke area and arcuate fasciculusis were higher than those of the right side,and the difference was statistically significant (all P ＜ 0.05).The FA value of observation group in the left Broca area was lower than that of the right side,and the difference was statistically significant (P ＜ 0.05);the FA values of observation group in the left Wernick area and arcuate fasciculusis were higher than those of the right side,but the difference was not statistically significance (all P ＞ 0.05).The FA values in the bilateral Broca area and arcuate fasciculusis of observation group were lower than those of the control group,the difference was statistically significant (P ＜ 0.05),those in the bilateral Wernick area were also lower than the control group,but the difference was not statistically significant (P ＞ 0.05).Conclusions The main pathogenesis for language development delay in cerebral palsy children was extensive damage in language functional areas,and Broca area and arcuate fasciculus were markedly impaired than Wernick area.

Objective To analyze the clinical feature of the patients with anti -N -methyl -D -aspartate receptor (NMDAR)encephalitis and feature of brain MRI and electroencephalogram (EEG)in children.Methods We reviewed the clinical manifestations,brain MRI and EEG features of 10 patients who were diagnosed anti -NMDAR encephalitis.Results Of the 10 patients,3 cases were male and 7 cases were female.The age was ranged from 13 months to 14 years (6 years and 11 months on average).No tumor was found in those patients.Main symp-toms included seizure in 9 cases,psychiatric symptoms in 10 cases,consciousness disturbance in 4 cases,involuntary movements in 8 cases,autonomic nerve instability in 5 cases,and sleep disorders in 10 cases.7 patients of MRI exami-nation were normal,2 patients revealed abnormal signal of temporal lobe,frontal,and parietal cortex.One patient revealed brain atrophy.All patients had abnormal EEG with diffusive slow waves,and some with focal spikes or sharp waves,left side abnormal more than right side.Conclusion Anti -NMDAR encephalitis can be found in children, even young boys may be affected.They have a lower incidence of tumors.Its predominant clinical features are psychi-atrics symptoms,seizures,involuntary movements and consciousness alteration.EEG was considered more significant than brain MRI.
