Objective To investigate the distribution and drug resistance of bacteria infection in children with pneumonia between pediatric intensive care ward and respiratory ward,in order to guide clinical treatment.Methods From 2010 January to 2014 January,two-hundred and sixty cases of pneumonia in hospitalized pediatric intensive care ward were included in the severe group,300 patients from respiratory ward into the common group,severe group were divided into the mechanical ventilation group (126 cases),non mechanical ventilation (134 cases),mechanical ventilation were divided into invasive ventilation group (94 cases),noninvasive ventilation group (32 cases).Conventional sputum specimens were detected,bacterial culture,identification and drug resistance of pathogenic bacteria ratio were done in each case,to compare the pathogenic bacteria and drug resistance rate of different groups.Results Both severe group and common group,gram negative bacteria were significantly higher than those of gram positive,But in the severe group,gram negative bacteria ratio was significantly higher than the common group (P ＜ 0.05),while the positive bacteria ratio was significantly lower than that of common group (P ＜ 0.05).Stenotrophomonas maltophilia,Acinetobacter and Pseudomonas aeruginosa ratio in severe group were significantly higher than that of common group (P ＜ 0.05),while the Haemophilus influenzae and Streptococcus pneumoniae in common group was significantly higher than the proportion of severe group (P ＜ 0.05).Stenotrophomonas maltophilia,Acinetobacter,Pseudomonas aeruginosa ratio in ventilation group was significantly higher than that of non ventilation group (P ＜ 0.05),and in the invasive ventilation group was significantly higher than the proportion of noninvasive ventilation group (P ＜ 0.05).Multi drug resistant bacteria detection rate in severe group was significantly higher than the common group (P ＜ 0.05).Conclusion Both pediatric intensive care ward and respiratory ward,bacterial lung infections are dominated by Gram negative bacteria,but bacteria spectrum and drug resistance have obvious difference,multi drug resistant bacteria detection rate in pediatric intensive care ward significantly higher than that of respiratory ward.Mechanical ventilation especially invasive mechanical ventilation may easily lead to drug-resistant strains.

Objective To compare the effects of intracoronary verapamil on coronary flow,myocardial perfusion and clinical outcome during primary percutaneous coronary intervention(PCI) for acute ST elevation myocardial infarction(STEMI).Methods A total of 99 consecutive STEMI patients undergoing primary PCI were randomly assigned to receive intracoronary verapamil or intracoronary heparinised saline immediately after stent deployment.Coronary flow was assessed by Thrombolysis in Myocardial Infarction(TIMI) flow grade(TFG) and corrected TIMI frame count(CTFC),and myocardial perfusion was assessed by TIMI myocardial perfusion grade(TMPG) and TIMI myocardial blush grades(MBG).Coronary and myocardial perfusion were assessed before and after PCI,as well as after drug administration by two doctors independently.Echocardiography were performed one week after PCI.Incidence of major adverse cardiac events in hospital and 3 months follow-up were compared between the two groups.Results Eight patients were excluded from the final analysis.Among the remaining 91 patients,47 patients were in the verapamil group and 44 patients were in control group.Baseline characteristics and angiographic characteristics were not significantly different between the two groups.CTFC,TFG,TMPG,and MBG before and after PCI were of no significant differences between the two groups.However,after drug administration,the verapamil group showed better outcome compared with the control group in CTFC(27.1?14.2 vs 39.0?23.8,P=0.011),TFG≥2(100% vs 90.9%,P=0.035),MBG≥2(91.5%% vs 75.5%,P=0.034),and TMPG≥2(89.4% vs 72.7%,P=0.042).LVEF measured by echocardiography was not significantly different between the two groups one week after PCI.The combined incidence of MACE in hospital(4.3% vs 9.1%,P=0.613) and at 3-month follow-up(23.9% vs 22.7%,P=0.894) was similar between the verapamil group and the control group.Conclusion Intracoronary administration of verapamil can improve coronary flow and myocardial perfusion in STEMI patients underwent primary PCI but show no obvious improvement in short-time clinical prognosis.

Objective To study the effect of TGF-?1 on the activation of ERK MAPK in human bronchial epithelial BEP2D cells. Methods Western blot was employed to examine the time-dependent activation of ERK MAPK by TGF-?1. BEP2D cells were harvested after treatment of human bronchial epithelial cells with 2 ng/ml TGF-?1 for 0, 10, 30, 60, 120, 240 and 480 min, respectively. Fluorescent dye staining and flow cytometry were employed to assess the apoptosis of BEP2D cells treated with vehicle, or with 2ng/ml TGF-?1, or co-treated with 2ng/ml TGF-?1 and 5?M U0126. Proliferation of BEP2D cells treated with vehicle, or with 2ng/ml TGF-?1 or 5?M U0126, or co-treated with 2ng/ml TGF-?1 and 5?M U0126 was assayed with colony-forming test, respectively. Morphological observation was performed to observe the morphological changes in BEP2D cells treated with vehicle, or with 5ng/ml TGF-?1 or 5?M U0126, or co-treated with 5ng/ml TGF-?1 and 5?M U0126, respectively. Results TGF-?1 activated ERK MAPK in BEP2D cell. The maximal activation of ERK MAPK took place at 60min after stimulation with 2ng/ml TGF-?1. TGF-?1 treatment effectively inhibited cell proliferation, and induced their apoptosis and epithelial-mesenchymal transition. Pretreatment with U0126, an inhibitor of ERK MAPK, significantly enhanced the TGF-?1-mediated anti-proliferation and apoptosis effects, and inhibited the effect of epithelial-mesenchymal transition of TGF-?1 in BEP2D cells. Conclusion TGF-?1-induced phosphorylation of ERK MAPK may participate in BEP2D cell proliferation and apoptosis regulation.

Objective To investigate the potential mechanisms of vascular dementia (VD) by comparing the neuroethological and pathological changes of two VD models, established with spontaneously hypertensive rat (SHR) and the rat, of which the bilateral carotid arteries were ligated. Methods Ten male SHRs were employed and defined as hypertension control group. Thirty male Wistar rats were randomly assigned to operation group (bilateral carotid arteries were ligated), sham group and control group. All rats enrolled in the operation group were undergone a permanent ligation of bilateral carotid artery (2-VO). The memory function of rats was estimated by the mean escape latency of Morris water maze. The morphological changes of neuron cells in the frontal lobe, temporal lobes, hippocampus and thalami were observed with HE staining, while the changes of white matter around cerebral ventricles were checked with LFB staining, and the demyelination of nerve was calculated. Results The memory function of rats in SHR control group and Wistar operation group was decreased compared with that of the rats in sham group and control group (P0.05). Conclusions SHRs without intervention and Wistar rats undergone 2-VO can be used to reproduce the ideal VD model. Both chronic permanent hypoperfusion and hypertension may lead to the loss of neurons and myelin which may result in memory dysfunction. Hypoperfusion is even more harmful than hypertension. The present study suggests that loss of neurons and myelin may play a role in the VD.

Objective To evaluate the value of bispectral index(BIS)monitoring as an indicator for extubation sedation level after children's oper?ation by total intravenous anesthesia. Methods One hundred and eighty children(2?13 years old)were randomly divided into six groups with 30 cases in each. Group A kept BIS 56?60,and Group B 61?65,Group C 66?70,Group D 71?75,Group E 76?80,Group F 81?85 till extubation. All children were given fentanyl,propofol and cisatracurium besilate when induced,and maintained with propofol and remifentanil. All cases kept BIS 40?55 during the operation. Then the changes of electrocardiogram,mean arterial pressure,heart rate,SpO2,postoperative complications and recovery time were observed. Results Groups A and B were extubated at deep anesthesia,cycle stability,but with high incidence of adverse reactions and awaked with a long time. Groups E and F were extubated when awaked,but with greater stimulation and easier agitation. Groups C and D were lighter hemodynamic responses,less respiratory effects and less postoperative complications of anesthesia. Conclusion The BIS level of 66?75 is a good se?dation level for extubation,especially in the level of 71?75.
