Protective effects of glycyrrhizin on adriamycin nephropathy in rats
Zhong Xi Yi Jie He Xue Bao , 2006,
Abstract: Objective: To observe the effects of glycyrrhizin on laminin (LN) expression in kidney tissue and excretory quantity of urine protein of rats with adriamycin nephropathy, and to explore the protective effects of glycyrrhizin on glomerulosclerosis. Methods: Eighteen SD rats were randomly divided into 3 groups: normal control group (n=6), untreated group (n=6) and glycyrrhizin-treated group (n=6). Adriamycin nephropathy was induced in rats in the last two groups by intravenous injection of adriamycin. The rats in the glycyrrhizin-treated group were fed glycyrrhizin for eight weeks, whereas the rats in the normal control group and untreated group were fed normal saline solution for eight weeks too. The levels of 24 h urine protein (Upr), serum creatinine (sCr), blood urea nitrogen (BUN) and serum cholesterol (Ch) of rats in each group were examined before treatment and after the treatment for four and eight weeks. The renal morphological changes were observed unders a microscope. The expression level of LN in renal tissue was detected by streptavidin-biotin peroxidase complex (SABC) method. Results: The levels of 24 h Upr after the treatment for four and eight weeks in the glycyrrhizin-treated group were both significantly decreased as compared with those in the untreated group. The pathological morphological changes of renal tissue in the glycyrrhizin-treated group were remarkably alleviated, and the expression level of LN in renal tissue was also decreased in the glycyrrhizin-treated group as compared with those in the untreated group. Conclusion: The glycyrrhizin exerts certain protective effects on adriamycin nephropathy in rats by reducing excretory quantity of urine protein, decreasing expression level of LN in renal tissue, improving renal function and lessening the severity degree of glomerulosclerosis so as to retard the development of glomerulosclerosis.
Social Motivations of Brand Naming from Adaptation Theory
Li-na SHI,Ping ZHANG
Studies in Literature and Language , 2010,
Abstract: Brand research is in full swing in the commodity area. Up to now the researches concerning the study of brand covers widely from brand naming to brand translation. However, research on the social motivations of brand naming in terms of adaptation theory is rare. Based on this theory, this paper aims to explore the influence of social motivations on brand naming for the purpose of having a good guidance of brand naming, making the brand more attractive and promoting the successful sales of commodities in the severe competition. Key words: adaptation theory; brand naming; social motivations; communicative context
Effects of a Care Workshop on Caring Behaviors as Measured by Patients and Patient Satisfaction  [PDF]
Hui-Shan Chan, Hui-Ying Chu, Hsiang Yen, Li-Na Chou
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.52010
Abstract: Caring is a central focus of nursing, and patient satisfaction is a critical indicator of nursing care quality. The aim of this study was to determine the effects that a care workshop exerted on nurse caring behaviors as perceived by patients and reflected by patient satisfaction. A quasi-experimental, pretest-posttest design without a control group was applied. The intervention consisted of several facets: 1) formal educational sessions twice a week for six weeks, 2) an angel-master mentorship activity, and 3) posts of exemplary caring behavior and stories. A demographic questionnaire, the Modified Nurse Caring Behaviors Inventory, and the Hartford Hospital Satisfaction Survey were used in this study. Descriptive statistics were analyzed to evaluate participant demographic characteristics. Paired t tests were used to determine the effects of a care workshop on nurse caring behaviors as perceived by patients and reflected by patient satisfaction. Of the 236 patients enrolled, 49.6% were women and 57.2% were admitted to medical-surgical units. Female patients rated nurse caring behaviors higher and reported greater patient satisfaction than did male patients on the pretest (p < 0.05) and 6-week posttest (p < 0.01). Patient with medical-surgical admissions rated nurse caring behaviors higher and reported greater patient satisfaction than patients with emergency admissions did on the pretest and 6-week posttest (p < 0.01). Nurse caring behaviors and patient satisfaction were positively correlated on the pretest (p < 0.05) and 6-week posttest (p < 0.01). Patient satisfaction scores increased after the intervention compared with the pretest scores (p = 0.000). Caring educational programs for nurses are commonly regarded to be an essential strategy for promoting care knowledge and practice and improving patient satisfaction. According to the favorable results of this study, care workshops must be provides to nurses in other units or hospitals in future studies.
Report of a Rare Distal Arthrogrophy Large Family

遗传 , 2004,
Abstract: We describe a seven-generation large family with talipomanus and talipes, 175 individuals in this family were involved. 32 affected individuals including 18 males and 14 femals whose clinical features were different and 1 suspicious male were found. The talipomanus were symmetrical, and varus and valgus were caused by vertical talus. We investigated their living environment, the dietary habit, obstetrical history, physical status, lifespan, and studied cytogenetics and so on. We propose these defects were rare distal arthrogrophy genetic disease.

心理科学进展 , 2011,
Abstract: Situational judgment tests are popular personnel selection tests in which the participants are presented the typical work-related situations and the probable behavioral responses, and are required to select or evaluate them according to the instructions. With the development of the theory and practices of SJTs, researchers are paying more attention to its validity, including construct validity, criterion-related validity, incremental validity, and impacts of instruction types, situational fidelity, scoring ...
Normobaric hypoxia-induced brain damage in wistar rat  [PDF]
Ding-Yu Hu, Qin Li, Bo Li, Rong-Ji Dai, Li-Na Geng, Yu-Lin Deng
Journal of Biomedical Science and Engineering (JBiSE) , 2009, DOI: 10.4236/jbise.2009.28092
Abstract: The biochemical indicators of wistar rat under low oxygen concentration, such as brain water content, necrosis, lactic acid and Na+-K+-ATPase, was detected to evaluate normobaric hypoxia-induced brain damage and to investigate the mechanism of wistar rat brain injury. Histopathological changes in brain tissue induced by hypoxia were investigated via hematoxylin and eosin stain (HE). Hypoxia induced factor-1α (HIF-1α) expression in brain was confirmed using immunohistochemistry. The results showed that the level of lactic acid was positively correlated with the degree of hypoxia, while concentration-dependent decrease in total Na+-K+-ATPase activity was observed. Compared with the control group, hypoxia group had a significant difference on brain water content under severe hypoxic conditions, the rate of brain necrosis increased obviously, followed by the increase of lactic acid level and the decrease of Na+-K+-ATPase activity. Histopathological analysis of brain confirmed that there was neuronal cell death in hippocampal gyrus. HIF-1α expression enhanced the hypoxia adaptation capability of the rat model through regulating the expressions of multiple genes. Lactic acid, Na+-K+-ATPase and HIF- 1α played an important role in brain injury as a possible mechanism.
Homotopy perturbation method for the solution of the electrostatic potential differential equation
Li-Na Zhang,Ji-Huan He
Mathematical Problems in Engineering , 2006, DOI: 10.1155/mpe/2006/83878
Abstract: This paper obtains an explicit analytical solution for nonlinear Poisson-Boltzmann equation by the homotopy perturbation method, which does not require a small parameter in the equation under study, so it can be applied to both the weakly and strongly nonlinear problems. The obtained results show the evidence of the usefulness of the homotopy perturbation method for obtaining approximate analytical solutions for nonlinear equations.
