Objective To explore the protective effects of peritoneal dialysis on tissue and organ damage induced by acute hemorrhagic necrotic pancreatitis (AHNP) . Methods Thirty-four AHNP patients were randomly divided into PD group ( n = 21) and control group (n=13). Control group was treated with conventional therapy, while PD group was treated with conventional therapy companied by intermittent peritonea] dialysis (IPD). Urinary and serum amylase, the plasma levels of TNF and IL-1, faecal occult blood test and serum leucocyte were examined. Functions of brain, kidney , liver and heart were observed. Results The protective effect was better in PD group than that in normal group (P

Objective To evaluate the safety,efficiency and short-term results of cutting balloon coronary angioplasty.Method This procedure was performed on 63 lesions in 52 patients (male 94%,age 57?9 years).Results The overall procedural success rate for the cutting balloon angioplasty without predilation were 92.1%.Seven out of 9 cases of total occluded lesions had satisfactory results.Two cases of in-stent restenosis were also treated with CB successfully.Forty-three lesions were treated with cutting balloon followed by stents insertion.In 20 lesions treated with the cutting balloon alone,there was a marked reduction in the luminal stenosis from 78.8?11.6% to 7.2?5.6%.One patient developed pericardial tamponade 3 hours after cutting balloon angioplasty,which was resolved with pericardiocentesis.No severe dissection,no abrupt coronary closure,no emergency bypass surgery and acute myocardial infarction occurred.During 6 to 2 months' follow-up,only one patient treated by cutting balloon alone experienced angina pectoris and coronary angiography showed a restenosis, there were no further cardiac event.Conclusion Cutting balloon coronary angioplasty is a safe and effective interventional therapy with a high success rate and satisactory short-term results.

Objective: To investigate the function and IL 1ra gene expression of neutrophils in hemodialysis (HD) patients. Methods: Gene expression was studied by reverse transcribe polymerase chain reaction (RT PCR) from untreated neutrophils in healthy controls and HD patients. Phagocytosis and bactericidal assays decreased in the number of viable extracellular and intracellular bacteria by colony counts. Results: Freshly isolated neutrophils spontaneously expressed icIL 1ra, sIL 1ra mRNA in HD patients. Phagocytosis and intracellular killing of neutrophils in HD patients impaired obviously when exposed to staphylococcus aureus in comparison with healthy controls. Conclusion: Untreated neutrophils in HD patients spontaneously express icIL 1ra and sIL 1ra mRNA, which is consistent with the suppressed phagocytosis and intracellular killing capacity. [

Objective To investigate the long-term efficacy of transendocardial injection of vascular endothelial growth factor (VEGF) into ischemic porcine myocardium.Methods Thirty pigs were divided into two groups:control group and treatment group (15 each).A angioplasty balloon was used to occlude the left anterior descending coronary arteries of the animals to reproduce a porcine myocardial ischemic model.Blank plasmid (control group) or constructed pIRES2-EGFP-hVEGF165 eukaryotic expression plasmid (treatment group) was directly injected into the ischemic myocardium through an transendocardial injection catheter of NOGA system,respectively.Before and one year after injection,left ventricular electromechanical mapping (LVEMM) was used to detect local linear shortening (LLS) and unipolar potential (UpV);M-mode local wall motion,cycle variation of integrated backscatter (CVIB) and left ventricular ejection fraction (LVEF) were detected by ultrasonagraphy.One year later,the animals were sacrificed for the observation of the capillary formation in myocardial tissue with immunohistochemical staining.Results One year after injection,as compared with that of control group,local linear shortening (LLS) showed a significant increase (P0.05),and ultrasonagraphy showed better heart function in the treatment group (P

Objective (1) To investigate the glucose and lipid metabolism 6-12 weeks after delivery in women with hyperglycemia during pregnancy. (2) To find out factors associated with the prognosis of women with hyperglycemia during pregnancy. (3) To investigate the feasibility of the diagnostic criteria set by the International Association of Diabetes and Pregnancy Study Group according to the follow-up data of women with hyperglycemia in pregnancy. Methods Clinical data of 262 women with hyperglycemia during pregnancy delivered in our hospital from January 1, 2007 to December 31, 2009 were collected. All patients underwent oral glucose tolerance test (OGTT) at 6-12weeks after delivery. They were divided into two groups according to the postnatal status of glucose and lipid metabolism. Multivariate Logistic regression model was used to analyze the factors affected glucose and lipid metabolism after 6-12 weeks of delivery. Results (1) Among the 262 women, 92(35.1%) were reported with abnormal glucose metabolism at 6-12 weeks of delivery, including one (0. 4 % ) woman with impaired fasting glucose, 81 (30. 9 % ) with impaired glucose tolerance, 4( 1.5 % )with impaired fasting glucose+impaired glucose tolerance and 6 (2. 3%) with diabetes mellitus.glucose levels in OGTT (OGTT 2hPG and the OGTT 3hPG) were risk factors for postpartum 0. 181-0. 918)]. (3) All markers of lipid metabolism were detected in 250 women with hyperglycemia during pregnancy at 6-12 weeks after delivery, the rate of abnormal postnatal lipid metabolism was 63.2%(158/250). In the abnormal group (n= 174), the most common abnormal marker was hypercholesterolemia (n = 126, 50. 4 % ), followed by high levels of low-density lipoprotein-cholesterol (n = 102, 40. 8 %), hypertriglyceridemia (n= 60, 24. 0 %) and low levels of high-density lipoproteincholesterol (n= 11, 4. 4 %). (4) Logistic regression model showed that elevated OGTT 2hPG was the risk factor for postpartum abnormal glucose metabolism [OR= 1. 364 (95%CI: 1. 063-1. 751)], while 0. 169-0. 851)]. Conclusions Women with hyperglycemia during pregnancy are more likely to present with abnormal glucose and lipid metabolism which commonly coexisted with insulin resistance.The risk factors for the postpartum abnormal glucose metabolism in mothers with hyperglycemia during pregnancy include early diagnosis, OGTT 2hPG and OGTT 3hPG, while the protective factor is breastfeeding. The risk factor for the postpartum dyslipidaemia in mothers with hyperglycemia during pregnancy is OGTT 2hPG, while the protective factor is high-density lipoprotein-cholesterol level in pregnancy.

AIM: To examine the inhibition of nitric oxid e (NO) synthesis during ischemic preconditioning (IP) on the induction of heat s hock protein 72 (HSP72) and infarct size-limiting effect of the second window of protection. METHODS: Rabbits were subjected to 4 cycles of 5 min of coronary a r tery occlusion separated by 10 min reperfusion, or received a sham operation. Du ring this procedure, N G-nitro-L-arginine methyl ester (L-NAME, an inhibitor of NO synthase) was injected intravenously 5 min before IP followed by its continu ous infusion. Twenty-four hours later, the hearts were rapidly excised for assay ing HSP72 expression or were subjected to 30 min coronary artery occlusion follo wed by 120 min reperfusion and then measured infarct size (IS). RESULTS: Twenty-four hours later, immunoblotting revealed an inc rease in HSP72 protein levels in the IP group, and this was blocked by L-NAME. I S of the IP rabbits was reduced as compared with the control (29 8%?3 7% vs 50 8%?4 3%, P
