BACKGROUND:Until now, little has been reported on establishment of pancreatic stem cell strains and lines,and the purification of pancreatic stem cells is difficult since the cell line establish rate is low.OBJECTIVE:To explore a more rational and effective technique of in vitro separation and continuous passage of pancreatic stem cells, with the hope to establish cell strains and even cell lines and to lay the foundation for the follow-up study of pancreatic stem cells in the treatment of diabetes.METHODS:Firstly, Percoll discontinuous density gradient centrifugation method was applied to separate the mouse pancreatic endocrine portion from the exocrine portion, then to obtain cell strains with highly proliferative ability and low differentiation from pancreatic endocrine portion-the islet. We used mouse embryonic fibroblasts treated with mitomycin C as a feeder layer, for in vitro continuous culture of islet-derived pancreatic stem cells under feeder layer conditions until they were transferred to the 30th passage to establish cell lines. Then pancreatic stem cell line derived from pancreatic islet was detected and identified by a series of tests including growth characteristic test, morphological observation, related molecular marker identification and differentiation characteristic identification.RESULTS AND CONCLUSION:In the continuous process of passage, pancreatic stem cells showed active proliferative ability, and maintained the typical morphological characteristics of stem cells and expression of pancreatic stem cell marker-Nestin. After induction, pancreatic stem cells showed insulin gene expression,reflecting their differentiation potential. Therefore, under the condition of feeder layer, the pancreatic stem cell line derived from Kunming mice was successfully established and the related identification was completed,which lays the foundation for the following research.

Objective To validate the clinical effect of evidence-based nursing on early rehablilitation of patients with acute myocardial infarction undergoing PTCA and intracoronary stenting. Methods 47 patients with acute myocardial infarction undergoing PTCA and intracoronary stenting were divided into the nursing group(24 cases)and the control group(23 cases).The nursing group received nursing with evidence-based nursing pattern while the control adopted routine nursing method. The nursing effect in the two groups was compared in the following aspects such as the incidence rate of adverse effect,average hospitalization days, athletic ability and psychological status. Results The incidenece rate of adverse effect Was lower(P＜0.05)and the average hospitalization days were shorter(P＜0.01)than those of the control group with addition of cardiovascular complications(P＞0.05).The athletic ability and psychological status were also superior to those of the control group(P＜0.05).Conclusion Application of evidence-based nursing could hasten the rehabilitative process of patients undergoing PTCA and intracoronary stenting.

OBJECTIVETo observe the clinical therapeutic effect of Shuizhitong capsule (SZT) in treating senile vascular dementia (VD) and on changes of related physio-chemical criteria.

METHODSEighty-five patients with VD were randomly divided into the treated group (n = 51) and the control group (n = 34) in the ratio of 3:2, treated with SZT and Piracetam respectively. Before and after treatment, the Zhang's Dementia Scoring (HDS) and Function of Social Activity Questionnaire (FAQ) scoring, cerebral blood flow and hemorrheologic properties were determined.

RESULTSSZT could significantly improve the patients' clinical symptoms, intracranial hemodynamic condition and the hyperviscosity, hypercoagulation and hyperaggregation status, lower the whole blood and plasma specific viscosity, raise the living standard of partial patients, with significant difference between before and after treatment (P < 0.05).

CONCLUSIONThe therapeutic effect of SZT in treating senile VD is definite.

BACKGROUNDPercutaneous transluminal renal angioplasty with stent is an effective procedure for atherosclerotic renal artery stenosis. However, the decision to perform this procedure has recently raised considerable debate. The aim of this study was to assess the effects of percutaneous transluminal renal angioplasty with stent in atherosclerotic renal artery stenosis patients, especially as it relates to blood pressure control and renal function improvement.

METHODSA retrospective analysis was made of the clinical data from 125 atherosclerotic renal artery stenosis patients who underwent percutaneous transluminal renal angioplasty from July 2004 to June 2008 in the Department of Vascular Surgery of Beijing Chaoyang Hospital. We compared blood pressure, number of oral antihypertensive medications, and renal function changes pre and post-procedure at 24 months follow-up.

RESULTSA total of 125 atherosclerotic renal artery stenosis patients underwent percutaneous transluminal renal angioplasty and 143 stents were placed. At 24 months follow-up, both systolic and diastolic blood pressure and the number of oral antihypertensive medications were significantly reduced (P < 0.05). Overall, the estimated glomerular filtration rate did not change significantly (P > 0.05); however, a significant increase in estimated glomerular filtration rate was observed in the subgroup of patients with a lower baseline estimated glomerular filtration rate and in the subgroup of patients with bilateral renal artery stenosis (P < 0.05).

CONCLUSIONPercutaneous transluminal renal angioplasty is a safe procedure for atherosclerotic renal artery stenosis patients, providing a significant improvement in blood pressure control and reduction in the number of oral antihypertensive medications.
