Objective To study the early resuscitation with intravenous administration of liquor in uncontrolled hemorrhagic shock model by four-staged abdominal aorta injury in rats in order to settle the controversy over the issue of volume resuscitation.Method Forty Sprague-Dawley rats were canulated with catheters into the left ventricle,femoral artery and femoral vein,respectively.Animals were subjected to vaseular injury of infrarenal pierced with a 25G needle leading to uncontrolled hemorrhagic shock.After aorta injury,the models were processed into 4 stages:early injured stage,early rescue stage,delayed rescue stage and observation stage.The rescue with rapid infusion of 45 ml/kg lactated Ringer's solution in 15 minutes in the early stage and the followed rescue in the late stage;and(4)sham-rescued.The MAP,CVP,lactic acid and Hct were monitored.The volume of blood loss and the survival time of rats were recorded too.Results After aorta injury,The MAP dropped from 94.3 mmHg to 25.8 mmHg and rised quickly after early resuscitation with rapid infusion of liquor and then again fell soon,and CVP did likewise.Lactic acid was increased and reached 3-4 times of baseline at 4 h in all group except Sham-resuced group.The Hct levels decreased quickly after resuscitation with liquor in early rescue stage and delayed rescue stage.The blood loss in abdomen increased after rapid infusion of lactated Ringer's solution in early rescue stage(blood loss increased from 22.8 ml/kg to 27.7ml/kg,P＜0.05).There Was no significant difference in mortality between those groups.Conclusions Rapid volume resuscitation at early stage of abdominal aorta injured with uncontrolled hemorrhagic shock cannot increase the circulatory blood volume for maintaining stable blood pressure norminimize the elevation of blood lactic acid.On the contrary,resuscitation with rapid administration of liquor at early stage can enhance blood loss and decrease the level of Hct.The survival time and survival rate can't be increased by early rescue with rapid liquor infusion.

Malnutrition is one of the most important factors for the prognosis of patients with gastric cancer,but the mechanism of malnutrition is unclear at present. These patients are at risk of nutritional deple-tion from anorexia,dysphagia,and may be associated with the presence of two or more of the following cyto-kines with metabolic activity such as TNF-α,IL-1,IL-6,interferon,leptin,nuclear factor-κB and so on, which are secreted by the host-tumor interaction. The cytokines constitute a sophisticated regulatory network. Therefore,the study of the relationship between malnutrition and related factors in patients with gastric cancer may improve the nutritional status and prognosis of these patients.

Objective To know the self-perceived burden (SPB) of young and middle-aged patients with first-attack of ischemic stroke and to analyze the influential factors of SPB as well as its relevance to the quality of life.Methods The patients' general information questionnaire,SPB Self-evaluation Scale,QOL-BREF were adopted to investigate young and middle-aged patients with first-attack of ischemic stroke.Results 100 patients were included,66 were male,34 were female.The Minimum age was 19.4 years old.The maximum age was 59 years old.The mean age was (50.80 ± 7.98) years old.The average SPB score was (24.21 ± 7.39) points,which was in the medium level.31 cases (31％) didn't have obvious SPB; 65 cases (65％) suffered mild-to-moderate SPB; 4 cases (4％) claimed they had severe SPB.There was negative correlation between the SPB and their quality of life.The multi-factor analysis showed that gender,the patients' understanding of disease,and caregivers' health situation were the influential factors of SPB.Conclusions Since self-perceived burden is common in young and middle-aged patients with ischemic stroke,clinical nurses should assess patients' self-perceived burden so as to provide targeted nursing intervention and health education,thereby to ease the burden on patients' self feeling,eventually to improve the level of their mental and physical health.

Objective To explore the value on the treatment of severe acute pancreatitis (SAP) by hemofiltration combined with Dan Sen and catheterizing drainage through laparoscope. Methods Thirty patients of SAP were divided into two groups. On the basis of routine treatment(supportive treatment,suppressing excrine of pancreas stilamin,trypsin inhibitor and antibiotics),hemofiltration,catheterizing drainage,stilamin and Dan Sen were added in group A,while only routine treatment were administered in group B. TNF,IL-6,IL-8,score of Balthazar CT and score of APACHEⅡ were studied in both groups. Results The value of TNF,IL-6,IL-8,score of Balthazar CT and score of APACHEⅡ in group A were significantly lower than those in group B(P

Objective To evaluate the prognostic value of combining postprocedural fibrinogen with high-sensitivity C-reactive protein (hs-CRP) in first time ST elevated myocardial infarction (STEMI) patients who had underwent successful primary percutaneous coronary intervention (PCI).Methods A total of 183 consecutive patients who had their first acute STEMI attack and underwent successful primary PCI were enrolled. Fibrinogen and hs-CRP levels were measured within 12 hours after PCI. All patients were followed up for 2 years. The primary end point was death of any cause. The secondary end point was a combined end point of death, non-fatal MI, heart failure (NYHA Ⅲ~Ⅳ),myocardial ischemia confirmed by stress test and revascularization. Results Postprocedural fibrinogen level correlated with hs-CRP level linearly (r=0.452, P

Objective To identify the changes of mesenteric lymph fluid in cases of uncontrolled hemor-rhagic shock (UHS), which is most often occurred in modem trauma and battle injury. The lymph of gut plays an important role during shock and MODS. The objective of this experiment is to identify the change of mesenteric lymph fluid in UHS. Method Thirty-eight SD rats were canulated with PE 50 catheters separately into right carotid artery,left femoral artery and femoral vein. A serf-made steel catheter was inserted into main mesenteric lymph duct and the mesenteric lymph fluid was collected. The rots were divided into three groups: control group (n=10), controlled hemorrhagic shock (CHS) group (n=10) and UHS group (n=10). After the mean blood pressure was dropped to 40 mmHg by exsanguination, hemorrhage was made by amputation of 75% tail in length and let the stump keep open to bleed. The volume of mesenteric lymph fluid was recorded, and the protein and endotoxin in it were examined, too. Data were analyzed using ANOVA and Chi-square test. Results The mesenteric lymph fluid was decreasing remarkably during shock until it was below 1/4 of normal. After hemorrhage was controlled, the mesentefic lymph fluid increased slowly. However, it kept decreasing persistently in cases of UHS. So did the protein content. The eudotoxin in lymph fluid increased 2 hours after CHS and one hour after UHS. There was significant difference in endotoxin between CHS and UHS 2 hours after shock (P<0.05). Con-dusions The volume and protein content of mesenteric lymph fluid decreased mare significantly in UHS than that in CHS. And contrarily, the endotoxin in lymph fluid increased more significantly in UHS than that in CHS. The change of the mesenteric lymph fluid may be an important cause of MODS after UHS.

0.05) . NNS could decrease blood viscosity and hematocrit, inhibit the aggregation of erythrocytes and platelet and increase the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH -Px). [Conclusion] NNS has an effect on AIS, which is similar to nimodipine. Its therapeutic mechanism may be related to the relief of cerebral ischemia by improving blood rheology and cerebral blood flow and protecting brain cells from injury by eliminating free radicals.

[Objective] To explore the protective mechanism of Naoxing Nasal Spray (NNS) on ischemic cerebral injury. [Methods] Seventy Wistar rats were randomized into 7 groups: high-dose NNS group (group A), moderate-dose NNS group (group B), low-dose NNS group (group C), nimodipine group (group D), model group (group E), solvent control group (group F) and pseudo-operation group (group G). Rat models of ischemia/reperfusion were established by blocking left middle cerebral artery. Plasma levels of tumor necrosis factor a (TNF-?) and interleukin 1? (IL-1?), malondialdehyde (MDA) content, activities of superoxide dismustase (SOD), glutathione peroxidase (GSH-Px) and nitric oxide synthase (NOS) in brain homogenate were detected. [Results] NNS decreased the contents of MDA, TNF-? and IL-1?, and increased the activities of SOD, GSH-Px and NOS. [Conclusion] NNS has protective effect on ischemic cerebral injury by promoting the clearance of free radicals, inhibiting the release of inflammatory mediator and increasing the synthesis of NO and thus to reduce injury of free radicals, inhibit the local inflammatory reaction and improve cerebral blood perfusion.
