Objective To investigate the role of fluid therapy in treatment of septic shock in children.Methods A total of 48 pediatric patients with septic shock were enrolled.Twenty-seven patients were treated with volume expansion and 21 patients were treated with fluid resuscitation.There were no differences in use of antibiotics,inotropic and vasoactive agent in two groups.The time needed for haemodynamic stability,occurrence of pulmonary edema.length of PICU stay,and mortality were compared between two groups.Results Compared with volume expansion group,the time needed for haemodynamic stability significantly decreased in fluid resuscitation group ((216.10± 168.13) minutes vs (121.63 ± 75.59) minutes) (P < 0.05). There were no significant difference in occurrence of pulmonary edema between volume expansion group and fluid resuscitation group (14.8% vs 9.5% . P > 0.05) .Compared with volume expansion group,length of PICU stay significantly decreased in fluid resuscitation group ((6.188 ±3.250) days vs (3.944±2.711) days,P < 0.05).Compared with volume expansion group,mortality significantly decreased in fluid resuscitation group (40.7% vs 14.3%,P < 0.05) . Conclusions Rapid fluid resuscitation was associated with early reach of haemodynamic stability,short stay in PICU,improved survival rate and no increase in the risk of complication in pediatric patient with septic shock.

Objective To determine the biological traits and optimal condition for the induction and differentiation of endothelial progenitor cells from peripheral blood in healthy adults. Methods Mononuelear cells were isolated from peripheral blood of healthy adults by Ficoll-density eentrifugation. The isolated ceils were cultured in 1640 medium supplemented with VECF165 and bFGF. The EPC specific surface mark CD34 and KDR were assessed by fluorescence activated cell sorter(FACS)analysis: EPC were characterized as adherent cells double positive for DiL-acLDL uptake and lectin binding by direct fluorescent staining under a hser scanning confocal microscope. EPC migration were assayed by MTr assay. Result The number and migration ability of EPC were increased by VEGFl65 and bFGF. Conclusion Endothelial progenitors cells can be derived from mononuclear cells of peripheral blood at specific conditions.

The endogenous microorganism in paridis rhizoma mainly includes bacteria and fungi,and shows different physiological activities,such as microorganism inhibition and anti-tumor activity. The principal active substance steroid saponin in paridis rhizoma can be generated from the fermentation liquor of some endogenous bacteria,and the chemical structure of vancomycin and progesterone can be transformed by the endophyte. It is supposed that paridis rhizoma may benefit from the attributions of the endogenous bacteria against illness and environment changes. It would also benefit in productivity, transformation and modification of the other active sub-metabolites and compounds in paridis rhizoma. Thus,it is valuable in drug development and source insufficiency alleviation of Chinese medicines through separation,identification,screening and clone of the endogenous microorganism in paridis rhizoma.

Objective To observe the effects of ischemic postconditioning (I-postC) on lung injury after limb ischemia reperfusion (LIR) in rats, and to investigate the protective effect and the mechanisms. Methods Twenty-four Wistar rats were divided into three groups:control group (group Control), ischemia-reperfusion group (group IR) and ischemic postcondi?tioning group (group I-postC). Referring to routine method in our department, the model rats underwent 4-hour ischemia and 4-hour reperfusion of hind limbs were made. In group Control, the rubber band around the limb was loose,which did not block the blood flow. Rats in group I-postC were given repeated 3 times of 5 min ischemia-5 min reperfusion, and then did perfusion 4 h before reperfusion. The blood and lung samples were collected for detecting arterial gas of partial pressure of oxygen [p(O2)] and partial pressure of carbon dioxide [p(CO2)]. The plasma and lung tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD) and xanthine oxidase (XOD) were detected. The morphological changes of lung tissue were ob?served under light microscope and electron microscope. Results It was found that after suffering from ischemia-reperfu?sion, levels of p(O2) and p(CO2) decreased significantly. The activity of SOD in plasma and lung tissues decreased, but XOD and MDA increased significantly (P<0.05). With microscope, lung interstitial vascular dilation, infiltration of neutrophils, the width of the alveolar space, alveolar septal thickening and alveolar exudate were found. Compared with IR group, it was found that p(O2) and p(CO2) increased significantly in group I-postC. The activity of SOD in plasma and lung tissues in?creased, but XOD and MDA decreased significantly(P<0.05). The mild damage of pathological changes were found. Conclu?sion Ischemic postconditioning can reduce the lung injury after limb ischemia reperfusion in rats, which may be related to the inhibition of lipid peroxidation.
