Objective To analyze the risk factors of acute kidney injury (AKI) in the patients undergoing gastrointestinal surgical procedures.Methods We retrospectively analyzed all gastrointestinal surgical patients nearly 2 years who were in the first affiliated hospital of Kunming Medical University and the first people's hospital of Yunnan province.Results The incidence of AKI was 2.1%.Univariate analysis and multivariate analysis indicated that: age>65 years, emergency operation and serious infection were significantly related with the incidence of AKI.Conclusion AKI is a common complication after gastrointestinal surgical procedures.This study showed that age>65 years, emergency operation, serious infection were risk factors most likely associated with postoperative AKI development.

Objective To explore the prevention and treatment of acute kidney injury (AKI) after gastrointestinal surgical procedures.Method We retrospectively analyzed the data of patients underwent gastrointestinal surgery in recent 2 years in the First Affiliated Hospital of Kunming Medical University and the First People's Hospital of Yunnan Province. Result The incidence of AK1 was 2.1%. Elderly patients with basic diseases had poorer prognosis than non-elderly patients. Conclusion In the patients after gastrointestinal Surgery, early rehydration, diuresis, ant-infection and preventive hemodialysis can achieve the goal of prevention and treatment of acute kidney injury in early stage.

BACKGROUND:Under mitomycin C treatment, feeder cells appear to have restricted proliferation, but they are stil able to secret different cytokines. Non-mesenchymal stem cells from the bone marrow and secreted factors in plasma maintain the micro-environment suitable for the growth of mesenchymal stem cells that can improve the yield of mesenchymal stem cells.
OBJECTIVE:To study the biological characteristics of C57 mouse bone marrow mesenchymal stem cells isolated using a whole bone marrow adherent culture technique.
METHODS:Using the whole bone marrow adherent culture technique, purified and amplified C57 mouse bone marrow mesenchymal stem cells were harvested. cellproliferation kinetics, immune cellsurface markers, multiple differentiation potential and cellcycle were detected.
RESULTS AND CONCLUSION:Using the whole bone marrow culture, mouse bone marrow mesenchymal stem cells were harvested and capable of adhering to the plastic culture vessel. The obtained cells expressed CD45, CD105 and Sca-1, but were negative for CD34, CD33 and C-kit. The doubling time was (57.11±1.5) hours. The cells could be induced to differentiate into osteoblasts, adipocytes and chondrocytes. The cellcycle analysis showed that 64%of cells were in G 0-G 1 phase. These indicates that C57 mouse bone marrow mesenchymal stem cells isolated using a whole bone marrow adherent culture technique have biological characteristics of mesenchymal stem cells.

Objective To observe the effect of active components(glycyrrhizic acid monoaminate,total ginsenoside and to-tal ophiopogonoside)of Zhi Gancao Decoction(ZGD)and their combination on the triggered activity and myocardial dam-age in the isolated ischemia -reperfusion rat heart.Methods Isolated rat heart was treated with L angendroff perfusion and monophase action potential technology was applied.Results &Conclusion Total extract of ZGD,single active c omponents and their combination can markedly l ower the incidence of cardiac triggered activity,prevent the myocardiu m from injury and decrease the incidence of arrhythmia induced by ischemia -reperfusion in rats and the effects of their com bination are positively related to the doses.

Objective To establish a type of porcine model for controlled Cardiac Deceased Donor.Method Using the wuzhishan miniature pig 2 ～ 4 months of age.After intravenous general anesthesia and respiratory,after open heart surgery to produce myocardial infarction model,to heartbeat stop completely,stop breathing machine and drug support,so we established a miniature pig cardiac death donor model.Record during the heart rate,systolic pressure,diastolic blood pressure,central venous blood pressure,blood oxygen saturation and regularly take on blood gas analysis.Before cardiac arrest,monitoring hemodynamic,blood gas analysis,and the time of death before the circulatory failure.After cardiac arrest respectively 0 min,15 min and 30 min,perfusion for donor organs (liver/kidney),get the pig's liver/kidney in the different time of the groups,observed the pathological changes of liver/kidney tissues by HE staining.Result The heartbeat stop completely occurs 7 ± 0.17 minutes after left descending coronary artery ligation and cease of assisted respiration in the different groups,systolic pressure,diastolic blood pressure,central venous pressure,blood oxygen saturation,CO2 partial pressure changed significantly;Immediately after cardiac arrest for compared group (0 min),schemia-reperfusion that group of 15 min after cardiac arrest injury is obvious,ischemia-reperfusion that group of 30 min after cardiac arrest injury is further.Conclusion Miniature pig donor model obtained in this method respiratory cycle failure stability,can be controlled,no adverse drug reactions,the organ ischemia-reperfusion injury caused by repetitive is better.
