ABSTRACT
ObjectiveTo discuss the prevention and treatment of the perioperative complications in endovascular treatment for arteriosclerosis obliterans (ASO) of lower extremities.MethodsEndovascular treatment was performed for 210 patients (248 limbs) with ASO of lower extremities,including 28 iliac lesions,76 femoral-popliteal lesions,56 inferior genicular lesions and 88 multiple segment lesions.The clinical data and complications were reviewed and analyzed.Results The technical success was achieved in 92.74％ (230/248).Perioperative complications occurred in 21 patients (21/210,10.00 ％),including hematoma (n= 6),pseudoaneurysm (n= 1),heart failure (n= 2),constrast-induced nephropathy (n = 1),artery perforation (n= 3),artery section (n = 3) and restenosis (n= 5).All the complications were relieved after corresponding treatment.ConclusionEndovascular treatment is a safe and effective method for ASO of lower extremities because of its high success rate and few complications.Effective control of systemic diseases,careful operation and regular treatment after operation are all the effective measures to prevent and reduce the occurrenceof complications.
ABSTRACT
The actin depolymerizing factor/cofilin (ADF/cofilins) are a family of actin-binding proteins expressed in all eukaryotic cells. The ADF/cofilins appear to have multiple functions, and this is reflected in their very complex association with both monomeric and filamentous actin. Phosphorylation by some kinases and other factors such as LIM kinases 1 and 2, TESK 1 and TESK 2 kinase, Insulin, etc, prevents ADF/cofllins from binding actin. The serial researchs of ADF/cofilins are increasingly becoming study hot spots, especially on the relationship between homo-sapiens disease and mechanism of action of ADF/cofilins.Now in this domain wilderness details are still far from clear, such as the mechanism by which actin filaments are depolymerized by ADF/cofilins has been controversial.
ABSTRACT
Objective To evaluate the changes in water, electrolyte and acid-base balance after seawater immersion in cases of open abdominal trauma associated with intestinal rupture, and to obtain a theoretical basis for the early treatment of open abdominal injury with intestinal rupture in naval combat. Methods A canine model of open abdominal trauma with intestinal rupture was established in 26 healthy adult dogs, and they were divided randomly into three groups. All animals were subjected to abdominal wall incision and intestinal rupture. Seawater immersion group(n=10) was immersed into artificial seawater after trauma; normal saline solution group(n=6) was immersed into normal saline solution after trauma; control group (n=10) had no immersion. The 3 groups were observed for changes in water, electrolyte and acid-base balance, and the results were analysed and compared. Results Signficant disturbance of water, electrolyte and acid-base imbalance were observed in the seawater immersion groups, but no significant changes of these parameters were seen in the control group and normal saline group. Conclusion Seawater immersion is the main factor leading to the disturbance of body metabolism after open abdominal trauma with intestinal rupture.
ABSTRACT
Objective To evaluate a protocol of early treatment for dogs suffering from open abdominal injury and seawater immersion. Methods A canine model of open abdominal injury was made with 30 adult health dogs. After 2 hours seawater immersion, the dogs were divided into two groups: treatment group( n =18) and control group(untreated group, n =18). The changes of survival rate, body liquid metabolism and hemodynamics were observed respectively. Results The survival rate significantly increased from 0 in control group to 94 4% in treatment group. The disorder of hemodynamics and body liquid metabolism was improved significantly, P
