Use of concept maps to promote electrocardiogram diagnosis learning in undergraduate medical students.

Concept mapping is an effective method in teaching and learning, however this strategy has not been evaluated among electrocardiogram (ECG) diagnosis learning. This study explored the use of concept maps to assist ECG study, and sought to analyze whether this method could improve undergraduate students' ECG interpretation skills. There were 126 undergraduate medical students who were randomly selected and assigned to two groups, group A (n = 63) and group B (n = 63).

Wnt and Notch signaling pathway involved in wound healing by targeting c-Myc and Hes1 separately.

Introduction: Wnt and Notch signaling pathways are critically involved in relative cell fate decisions within the development of cutaneous tissues. Moreover, several studies identified the above two pathways as having a significant role during wound healing. However, their biological effects during cutaneous tissues repair are unclear.

Prevalence and fluoroquinolone resistance of pseudomonas aeruginosa in a hospital of South China.

Pseudomonas aeruginosa is an opportunistic pathogen that poses a threat in clinical settings. This study aimed to investigate the molecular characterization and epidemiology of fluoroquinolones (FQs) resistance in P. aeruginosa isolated from South China.

Molecular epidemiology of aminoglycosides resistance on Klebsiella pneumonia in a hospital in China.

To investigate the molecular epidemiology of aminoglycosides resistance among Klebsiella pneumonia in hospitals in China, the antibiotics resistance and the possession of extended-spectrum β-lactamases (ESBLs) from 162 isolates were examined using Kirby-Bauer disk diffusion and PCR sequencing. Overall, 47.5% (77/162) of strains showed an ESBL phenotype.

Comparative serum proteome expression of the steroid-induced femoral head osteonecrosis in adults.

Steroid-induced osteonecrosis of the femoral head (SONFH) is a disabling, aseptic and ischemic disease that develops following steroid therapy. The pathogenesis of SONFH is unclear, so the early diagnosis and treatment for this disease is yet to be established. The purpose of the present study was to identify potential biomarkers for SONFH.

Experimental study of comparing rhEGF with rhβFGF on improving the quality of wound healing.

The mechanism and biological effects of comparing recombinant human epidermal growth factor (rhEGF) with recombinant human basic fibroblast growth factor (rhβFGF) were evaluated on the model of incised wounds on ventral side of rabbit's ears in order to direct their medication in clinical. Total of 72 incised wounds on ventral side of 24 New Zealand rabbits' ears were divided randomly into two therapeutic groups (rhEGF group with 10 μg/cm(2) and rhβFGF group with 100 AU/cm(2)) and a control group (1% silver sulfadiazine cream, SD-Ag). The observation of wounds, the measurements of healing wound area, the calculation of wound closing index, the histopathological examination, the electrical microscopic examination, and the expression of examining integrin β1 mRNA of samples of three groups by in situ hybridization technique were used to evaluate the results of wound healing.
