Objective The experiment aims at probing the best condition of the isolation and purification of rat islets. Methods The islets were isolated from rat pancreas by hepatopancreatic duct perfusing with collagenase and purified with Ficoll 400 discontinuous density gradient centrifugation.Then the purified islets were subjected to histological staining,electron microscopy and radioimmunoassay for identification of specificity and viability. Results The histological staining revealed that the viability and the purity of the purified islets were above 95% and 85% respectively.Electron microscopy showed that the purified islets were morphologically intact with clear membrane and plenty of secreting granules.Radioimmunoassay demonstrated the secreted insulin concerntration between low-glucose groups and high-glucose groups varied significantly,which verified the good function of the islets.Conclusion Hepatopancreatic duct perfusing with collagenase is a good method for digestion.There are many factors that influence the quantity and quality of the acquired islets,such as the completed expansion of pancreas,the concentration and viability of collagenase and the digested time,etc.

Objective:To explore influence of low high density lipoprotein cholesterol (HDL‐C) level on kidney func‐tion in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) .Methods :A to‐tal of 300 CHD patients ,who were treated and received PCI in our hospital from Feb 2012 to Jun 2014 ,were select‐ed .According to HDL‐C level ,they were divided into normal HDL‐C level group (n=179 ,HDL‐C≥1. 04 mmol/L) and low HDL‐C level group (n= 121 ,HDL‐C< 1.04 mmol/L) .Baseline data were compared between two groups ,and multi‐factor Logistic regression analysis was used to analyze risk factors for kidney injury after PCI .Re‐sults:Compared with normal HDL‐C level group ,there were significant rise in percentages of overweight (30.73%vs .39.67% ) ,smoking history (29.05% vs .41.32% ) ,myocardial infarction history (35.20% vs .46.28% ) ,left ventricular ejection fraction (LVEF) <50% (18.99% vs .24.79% ) ,anemia (16.20% vs .27.27% ) and kidney in‐jury (12. 85% vs .22. 31% ) in low HDL‐C level group , P<0. 05 or <0. 01. Multi‐factor Logistic regression analysis indicated that age ,myocardial infarction history ,anemia ,LVEF<50% ,diabetes mellitus ,dosage of contrast agent and low HDL‐C level were risk factors for kidney injury in CHD patients after PCI (β=0.499~1.171 ,P<0.05 or<0.01) .Conclusion:Low HDL‐C level is a risk factor for renal function injury in CHD patients after PCI .

ObjectiveTo investigate the effect of age on long-term prognosis of patients with traumatic brain injury (TBI).Methods102 inpatients with TBI were evaluated by following-up, using Glasgow Outcome Scale (GOS), Functioning Item of Disability Rating Scale (DRS-F) , Employability Item of Disability Rating Scale (DRS-E) and Quality of Life Index (QLI).ResultsThe average age of 102 cases was 29.7±12.5. There were no significant differences among different groups in GOS and DRS-F (P>0.05), but the level of DRS-E or QLI showed much higher in <27 years old group than those in >45 years old group (P<0.01).ConclusionThe factor of age may affect the long-term prognosis of TBI, quality of life and employability of young patients are better than elder patients.

This article was aimed to study the effect ofXiao-Qing-LongDecoction (XQLD) on plasma AngⅡ, ALD, Na+-k+-ATPase content, and plasma AT1 and AT2 mRNA expressions in Cor pulmonale rats, in order to further explore the mechanism of ventilating lung qi for diuresis. A total of 60 Wistar rats were randomly divided into the normal group, model group and XQLD, with 20 rats in each group. The enzyme-linked immunosorbent assay (ELISA) method was used to determine the AngⅡ, ALD and Na+-k+-ATPase content. The fluorescence quantitative PCR was used to detect the AT1 and AT2 mRNA expression. The results showed that compared with the normal group, the AngⅡ, ALD and Na+-k+-ATPase contents in the model group were significantly increased (P< 0.05, orP< 0.01). Compared with the model group, the AngⅡ, ALD and Na+-k+-ATPase contents in the XQLD group were obviously decreased (P< 0.05). Compared with the normal group, AT1 mRNA expression was increased; and AT2 mRNA expression was decreased in the model group (P<0.05, orP< 0.01). Compared with the model group, AT1 mRNA expression was decreased; and AT2 mRNA expression was increased in the XQLD group (P < 0.01). It was concluded that XQLD can effectively regulate the AT1 and AT2 mRNA expressions, influence ALD content to ventilate lungqi for dieresis.
