Objective To analyze the implementation effects of peer-assisted learning on critical thinking ability of undergraduate nursing students. Methods A total of 411 college nursing students were selected with 203 students of Class One, Class Three, and Class Five from Grade 2012 majoring in nursing were taken as the control group, 208 students of Class Two, Class Four, and Class Six as the experimental group. In the course of basic nursing practice, the control group was trained by the traditional practice, and the experimental group was trained by the way of peer mutual aid. Critical thinking disposition inventory Chinese version (CTDI-CV) was adopted to evaluate the level of critical thinking ability of the nursing students of both groups. SPSS 17.0 was used and the data of the two groups were compared by t test. Results The score of experimental group students' critical thinking ability and the score of 7 dimensions including their seeking truth, analysis ability, self-confidence, inquisitiveness, cognitive maturity, open mind and systematic ability were higher than those before the experiment (P<0.05). The total score of the experimental group students' critical thinking ability and the score of 5 dimensions including seeking truth , analysis ability, self-confidence, curiosity and cognitive maturity were higher than those of the control group (P<0.05). Conclusion Peer-assisted learning is beneficial to the improvement of critical thinking ability of nursing undergraduate students.

Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

Objective To study the effects of atorvastatin on expression of lysyl oxidase(LOX) in myocardial tissue of rats with diabetic cardiomyopathy (DCM) and its mechanism.Methods Thirty DCM SD rats were randomly divided into 3 groups:DCM group,treatment group (atorvastain 2 mg · kg-1 · d-1 by gastric gavage) and β-aminopropionitrile group(β-aminopropionitrile 80 mg · kg-1 · d-1 by gastric gavage),10 cases in each group.Other 10 SD rats were selected as the control group.At the end of week 8,the rats were killed for extracting the myocardial tissue RNA and protein.Expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in myocardial tissue of DCM rats were measured by RT-PCR and Western blot.Results The expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in the DCM group were significantly higher than those in the control group (P＜0.01),and compared with the DCM group,the expression of BAPN LOX,MMP-2 and NF-κB mRNA and proteins in the treatment group were significantly deceased (P＜0.01).Conclusion Atorvastatin can reverse the expression of LOX in myocardial tissue of DCM rat,and then may regulate the expression of MMP-2 and NF-κB.

Objective To observe the effects of the third-stage community-based rehabilitation program on functional recovery of stroke patients with hemiplegia. Methods 158 stroke patients with hemiplegia were divided into rehabilitation group and control group. Besides normal medicine and first-stage institution-based rehabilitation similar with that of control, rehabilitation group received a standardized third-stage community-based rehabilitation. They were assessed with the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) and Modified Rankin Scale (MRS) before, 1 month and 6 months after treatment. Results The scores of the FMA and the MBI of the rehabilitation group were higher than that of the control group (P<0.01), while were lower of the NIHSS and MRS in the rehabilitation group than in the control group at the end of the sixth month (P<0.01). Conclusion The third-stage community-based rehabilitation may improve the recovery of the stroke patients with hemiplegia.

Objective To study the changes of transforming growth factor-β1(TGF-β1) in pulmonary fibrosis induced by paraquat (PQ) with immunohistochemistry method. MethodsA total of 58 C57BL/6J male mice were randomly (random number) divided into the experimental group and control group. Pulmonary fibrosis was induced by intra-peritoneal injection of PQ in dose of 10 mg/kg into the mice of experimental group (n = 48), while physiological saline was used instead in mice of control group (n = 10). The mice of experimental group were sacrificed 2, 5, 7 and 14 days after PQ poisoning and the mice of control group were sacrificed on the 7th day after saline administration. Lungs of mice were taken and histological changes in lungs were evaluated by haematoxylin-eosin stain, and TGF-β1 was determined with immunohistochemistry method. The integrated optical density (iOD) value of TGF-β1 was measured and analyzed. ResultsThe TGF-β1 was markedly increased in macrophages during the genesis of pulmonary fibrosis induced by PQ. As the course of fibrosis progressed, the positive staining of TGF-B1 was mainly seen in macrophages and neutrophil's cytoplasm. On the 14th day after PQ poisoning, TGF-β1-positive cells were also detected in the fibroblast and myo-fibroblast inside the fibroblastic foci. Compared with the control group, the iOD value of TGF-β1 increased in experimental group (P ＜ 0. 01 ) and it gradually upgraded during the course of fibrosis. Conclusions The TGF-β1 significantly increased during the course of pulmonary fibrosis induced by PQ and played an important role in the pathogenesis of the disease.
