PURPOSE: The purpose of this study was to investigate factors which influence freshmen nursing students' problem solving abilities. METHOD: The data were collected from 119 students by means of self-reported questionnaires measuring problem solving abilities, critical thinking disposition, and self-directed learning, on March 7th and 11th, 2010. RESULT: For problem solving ability categories, the level of problem discovery was the highest followed by solution plan, problem definition, solution evaluation and solution implementation. The influencing factors on problem solving abilities of nursing students were critical thinking disposition, self-directed learning and gender. CONCLUSION: Using the results of this study as a foundation, nursing education curriculum should be comprised of critical thinking skills and self-directed skills for the improvement of nursing students' problem solving abilities. It is also recommended that further studies be conducted in order to investigate comprehensive curriculum designs that allow for maximum accumulation of these proficiencies.

BACKGROUND: Oxygen-glucose depdvation (OGD) in cultured neurons simulates stroke to a certain degree and plays an important role in studying processing and pathophysiological mechanism of ischemic neuronal injury.OBJECTIVE: To produce experimental OGD models in cultured neurons.DESIGN, TIME AND SETTING: A grouping controlled study was performed at the Center Laboratory of Third Hospital, Peking University from January 2007 to March 2008.MATERIALS: Fetal Wistar rats with gestational age of 17-19 days were collected in this study.METHODS: Primary cultures of cortical neurons that were derived from fetal Wistar rats with gestational age of 17-19 days were performed to remove pollutional non-neuronal cells. OGD was produced by incubation with non-glucose balanced salt solution and 2% Oxyrasa in 7-day cultured cortical neuron cultures. Cell cultures were kept in a humidified 37 ℃ incubator. In the control group, cell culture medium was replaced with balanced salt solution containing 20 mmol/L glucose. In the sham operation group,balanced salt solution containing 20 mmol/L glucose and Oxyrasawere used to replace the medium.MAIN OUTCOME MEASURES: Oxygen concentration in the culture medium was measured with blood gas analysis; neuronal death in the experimental group was observed under phase contrast microscope; lactate dehydrogenase activity was detected with lactate dehydrogenasa assay; effect of oxygen-glucose deprivation on neuronal viability was observed with trypan blue staining.RESULTS: Measurement of oxygen concentration showed that hypoxia could be quickly achieved shortly after the addition of Oxyrase; lactate dehydrogenase assay revealed that after treatments of neuron cultures with Oxyrase and non-glucose balanced salt solution, lactate dehydrogenase release increased significantly with the treatment time; trypan blue staining and phase contrast microscope showed that cell viability decreased after treatments of Oxyrase and non-glucose balanced salt solution, and most neurons died 6 hours after OGD.CONCLUSION: These results show that Oxyrase, together with non-glucose balanced salt solution, can be conveniently used to produce OGD condition in cultured neuronal cells which is greatly useful in the study of simulating cerebral ischemia in vitro.

Candida albicans cystitis is an uncommon but well described complication of modern therapeutics. The significance of systemic factors in the defense of the urinary tract against candidal infection is unknown. However, secretions from the prostate grand in men and from periurethral glands in women have been reported to be fungistatic. Conditions that predispose to candiduria include diabetes mellitus, antibiotic and corticosteroid therapy and disturbance of urine flow. Cystoscopy with bladder biopsy are necessary to rule out bladder tumor. We report a case of BPH with candidal cystitis and review the relevant literatures.
