Objective To identify the clinical evaluation methods used for undergraduate nursing students. Methods A self-made questionnaire about the clinical evaluation methods for undergraduate nursing students was used to collect information from 158 tutors of undergraduate nursing students in 4 teaching hospitals in Sichuan province. Results In terms of consulting evaluation opinion from other nurses, there was no significant difference between the ratios of tutors who really adopted and those who perceived as necessary to do so (Pgt;0.05). As for consulting the self-evaluation of nursing students and patients’ evaluation opinion, the ratio of tutors who really adopted was lower than those who perceived as necessary to do so (Plt;0.01). The majority of tutors used real, ward patients for evaluation, while a minority of tutors used demonstration room and model patients. The most effective methods viewed by the tutors were observation, holistic nursing care examination and test, and the most often used evaluation methods were clinical skill test, observation and theoretical exam. Most tutors adopted a continuous evaluation method for the clinical evaluation of undergraduate nursing students. Conclusion The methods for the clinical evaluation of undergraduate nursing students varies. This may influence the accuracy, objectivity and fairness of the evaluations. Formulating evaluation sheet of patients and self-evaluation sheet of nursing students, establishing standardized clinical skill examination station, training standardized patients and evaluation skills of clinical tutors, standardizing examination content and relevant evaluation standard and methods, and adopting comprehensive evaluation with various methods may help to improve the accuracy, objectivity and fairness of the clinical evaluation of undergraduate nursing students.
ObjectiveTo establish a rat model of diabetic microangiopathopathy and simulate the biochemical and pathological changes of diabetic retinal and renal microangiopathopathy. MethodsForty healthy male Sprague-Dawley rats were randomly divided into blank group and model group (10 and 30 rats, respectively). After the rats in blank group and model group were fed ordinary diet and high-fat and high-sugar diet for 5 weeks, respectively, the rats in model group were injected with 1% streptozotocin (STZ) through the abdominal cavity at the dose of 35 mg/kg to establish a type 2 diabetes model. After modeling, the rats were continuously fed until the 10th week (4 weeks after modeling), the general conditions of the rats were observed, and samples were collected for follow-up experiments. Serum creatinine (CREA), triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), microalbuminuria, urinary creatinine (UCr) and urine sugar were detected. Calculate the kidney index and microalbumin/urinary creatinine ratio (UACR). Optical coherence tomography angiography (OCTA) was used to observe the vascular changes and non-perfusion area of retinal superficial capillary plexus. The morphological and structural changes of kidney and retina were observed by hematoxylin-eosin and periodate Scheff staining. The expression of nerve fibers and nucleus of Müller cells in rat retina was observed by immunofluorescence staining. Ultrastructural results of retina were observed by transmission electron microscope. Independent sample t test was used for comparison between groups. ResultsFour weeks after modeling, compared with blank group, the body weight of rats in model group was significantly decreased, and random glucose was significantly increased, with statistical significance (t=5.755, －51.291; P＜0.05). Renal index, urinary glucose and UACR were significantly increased, while UCr was significantly decreased, with statistical significance (t=10.878, 137.273, 3.482, －6.110; P＜0.05). CREA decreased, TG, TC, HDL-C, LDL-C increased, and the differences were statistically significant (t=－28.012, 33.018, 118.018, 13.585, 16.480; P＜0.05). OCTA examination showed that there was no perfusion area of shallow retinal capillaries. The optical microscope showed that the inner boundary membrane of retina in model group was swollen and thickened, the surface was uneven, the inner and outer nuclear layer cells were disordered and the density decreased. Glomerular congestion was accompanied by cortical tubular epithelial swelling, widening of the mesangial area, and thickening of the basement membrane. The results of immunostaining showed that the inner and outer plexiform layers of the retina showed lamellar strong green fluorescence expression, and the inner and outer nuclear layers showed scattered dot green fluorescence expression. Transmission electron microscopy showed that the basal membrane of retinal microvessels in model group was slightly thickened, vascular endothelial cells edema, endothelial nucleus and perinucleus contraction, nuclear membrane contraction, mild mitochondrial swelling, vacuolation. ConclusionHigh-glucose and high-fat feeding plus a single intraperitoneal injection of STZ 35 mg/kg can successfully establish a microangiopathic model of type 2 diabetes.

ObjectiveTo set up the evaluation form for classroom teaching quality in nursing humanities concern education, in order to conduct the evaluation on nursing teachers in their teaching of humanistic concern in their nursing class teaching. MethodsWe applied the Delphi approach to consult 16 nursing experts to screen the evaluation indicators combining with the method of dispersion degree. Analytic hierarchy process was carried out to determine the indicator weight to establish the evaluation form. Then we used the form to investigate a small sample of 37 nursing teachers. According to the test results, we checked the reliability and validity of the evaluation form. ResultsThe evaluation form was finally determined. It consisted of five level-1 indicators as well as 23 level-2 indicators. The results of Cranach's α showed that the internal consistency reliability and sensitivity of the evaluation form were very high. The results of Spearman correlation analysis showed that the construction of the evaluation form was quite reasonable. The results of factor analysis showed that the discriminant validity of the evaluation form was quite good. ConclusionThe evaluation form is true, credible and reasonably built. It may be used for self-assessment by the teachers, mutual evaluation as well as evaluation of teachers by leaders or experts for the assessment of humanistic teaching in nursing classes.
Objective To design a novel stentless porcine aortic bioprosthesis and test the feasibility and its function in vitro after the valve was implanted by a modified method. Methods Six stentless porcine aortic bioprosthesis were divided into two groups according to different implantation, single layer suture group: new improvement stentless porcine aortic bioprosthesis sutured with single layer was implanted; double layer suture group: stentless porcine aortic bioprosthesis developmented by our laboratory used double layer suture was implanted. Each group contained three scales: 23 mm ,25 mm and 27 mm. Analogue ex vivo aortic valve replacement was performed , the feasibility of the new implantation was detected. Effective orifice area, transvalvular pressure gradient and regurgitation ratio were recorded at the cardiac output of 2.0 L/min, 3.5 L/min, 5.0 L/min and 7.0 L/min under the guideline of International Organization for tandardization （ISO）5840. Results The average aortic valve implantation time used for single layer suture and tradition double layer suture were 50 min and 70 min respectively. The transvalvular pressure gradient in the single layer suture group were significantly lower than those in double layer suture group under the flow of 5.0 L/min in 23 mm valve and 27 mm valve （13.51±0.51 mm Hg vs. 14.44±0.99 mm Hg, 7.36±0.19 mm Hg vs. 7.53±0.28 mm Hg；P＜0.01）;and the effective orifice area in the single layer suture group were larger than those in double layer suture group in the same case(1.87±0.06 cm2 vs. 1.76±0.08 cm2, 2.26±0.07 cm2 vs. 2.16±0.05 cm2；P＜0.01).
