Objective To establish a method of isolating and purifying islets from Wistar rat, and to evaluate the biological characters of the isolated and purified islets. Methods The pancreases were surgically removed from adult Wistar rats, carefully minced with scissors as small as possible prior to incubation in 0.9 mg/ml collagenase (Sigma, type Ⅴ) for 10~17min at 37℃. The digested tissue was filtered through a 60 apertures/cm~2 metal sieve and washed with 10% fetal bovine sera (FBS) in Hank’s solution. Purification was performed using Dextran discontinuous density gradient centrifugation to separate the contents of the postcollagenase pellets. Islet samples were stained with DTZ staining for identification. The viability of the purified islet was determined by acridine orange/propidium iodide (AO/PI) double staining. The in vitro function was assayed by different densities of glucose incubating islets for 45min, respectively. Insulin secretion in the supernatant was assayed by radioimmunoassay. Islets were transplanted under the kidney capsule into recipient SD rats that had been rendered diabetic by injecting streptozotocin 50mg/kg, so as to evaluate the in vivo function of islets. Results The islets were recovered between the 11% and 22% Dextran layers, and between the 11% and 1640 layers. The average number of isolated islets was 2181?14 per rat pancreas. After a discontinuous Dextran density gradient purification, about 1826?24 islets were obtained from per rat pancreas, with an average purity over 95%. Islets showed good response to glucose and high efficiency to invert hyperglycemia 7-10d after transplantation. Conclusion These results showed that the digestion methods and purification procedure which we have developed could provide islets from rats for transplantation studies. The biological characters of islets harvested by our method were very well.

Objective In order to evaluate the nutritional effect of early enteral nutrition in patients of Chinese domestic gastric cancer surgery,using evidence-based medicine methods,and supply evidence for clinical nutrition intervention.Methods CBM,Chinese academic Journals,Wanfang database and VIP Information Resource System were searched from January 2000 to March 2013 to collect the published clinical randomized controlled trials literatures of nutrition support in patients of Chinese domestic gastric cancer surgery according to inclusion and exclusion criteria of literature,using the Cochrane System Evaluation Handbook independent,double-blind principle of the literature methodology quality evaluation.Finally Meta analysis was conducted by using RevMan5.2 software.Results 14 articles were enrolled in the study,Meta analysis results showed that:early enteral nutrition comparing with parenteral nutrition in postoperative gastric cancer patients:the WMD of serum albumin was 1.55,95％ CI (0.81,2.29); the WMD of serum transferrin was 0.34,95％CI (0.30,0.38);the WMD of postoperative anal exhaust time was-20.66,95％CI (-23.91,-17.40).Conclusions Early enteral nutrition is better than the parenteral nutrition,which can restore adequate serum protein source for patients,and can recover the gastrointestinal digestion and absorption function of itself earlier,which is worthy of clinical promotion.

Objective To investigate the empathy of clinical nurses and analyze the influencing fac-tors.Methods Totally 465 clinical nurses were investigated with demographic data and interpersonal Reactivity Index-C (IRI-C).Results Mean score of the empathy of clinical nurses was (53.77±8.99)points with a medium level.Age,working years,whether or not to engage in management work were the main predictors of empathy.There were no significant differences in nurses with different genders,marital status,professional titles,education degree,hospital grades.Conclusions The length of the working years is one of the important factors of nursing unit.Common clinical nurses should be involved in the nursing manage-ment.Clinical nurses should pay attention to the study and discussion about empathy knowledge in order to improve their level of empathy.

Hydroxyapatite (HAP) formation on the surface of the degradable polyamides implant by a coating technology was studied. A suspension of HAP-glutin-acetic acid was prepared and brushed on the surface of the implant at room temperature. Scanning electron microscopy (SEM), X-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FT-IR) were employed to study the composition and the microstructure of the coating. The results obtained indicate that the main composition of coating is crystal HAP, its structural formula is Ca10(PO4)6(OH)2. So the coating has bioactivity. The coating has also small pores, which can stimulate bone regrowth and adsorption of other bioactive materials or mediine. This technology is an effective method to improve medical performance of the polyamides implant.
