ObjectiveTo compare the accelerating effect of topical recombinant human epidermal growth factor (rhEGF) and recombinant bovine basic fibroblast growth factor (rb-bFGF) on wound healing after fractional CO2 laser therapy.MethodsTwenty male guinea pigs were included in this study.After hair removal and irradiation with fractional CO2 laser,the back of each guinea pig was divided into 4 regions to be topically treated with rhEGF of 10 μg/cm2 (rhEGF group),rb-bFGF of 262.51 IU/cm2 (rb-bFGF group),the combination of rhEGF and rb-bFGF (combination group),or normal saline (control group),twice daily until the healing of wound.Skin physiology parameters including elasticity index and melanin index were detected before the irradiation,7,14 and 28 days after the irradiation,and compared between the 4 groups by analysis of variance.Tissue specimens were obtained from 4 mice at the above time points and subjected to pathological examination for the observation of collagen fibers and quantification of fibroblasts.ResultsAfter fractional CO2 laser therapy,the crusts fall off completely in growth factor-treated regions,while partly in the control regions,within 3 to 7 days; the wounds healed completely in 14 to 28 days in all the groups,with the regenerating tissue being more tender and redder compared with the surrounding unirradiated tissue.The wound surface was smaller in area and redder in color in the 3 growth factor-treated groups than in the control group.At 28 days after the irradiation,the elasticity index was 262.29 ± 62.40 in the combination group,202.00 ± 65.62 in the rhEGF group,188.86 ± 35.02 in the rb-bFGF group,167.14 ± 42.49 in the control group.Statistical difference was observed in elasticity index,but not in skin melanin index among the 4 groups.Pathological examination showed a dense and organized arrangement of collagen fibers in the combination group but a sparse and disorganized arrangement of collagen fibers in the control group.ConclusionThe combined application of rhEGF and rbbFGF can accelerate the healing of wound and increase the elasticity of regenerating tissue after fractional CO2 laser therapy.

The effects of high-intensity pulsed electromagnetic stimulation (HIPEMS) on proliferation and differentiation of neonatal rat neural stem cells in vitro were investigated. Neural stem cells derived from neonatal rats were exposed to 0.1 Hz, 0.5-10 Tesla (T) [8 groups of B-I, respectively], 5 stimuli of HIPEMF. The sham exposure controls were correspondingly established. Inverted phase contrast microscope was used to observe the cultured cells, MTT assay to detect the viability of the cells as expressed by absorbance (A) value, and flow cytometry to measure differentiation of neural stem cells. The results showed that A values of neural stem cells in both 3.0 T and 4.0 T groups were significantly higher than the other groups 24 to 168 h post HPEMS, indicating a strong promotion of the growth of neural stem cells (P<0.05). The A values of neural stem cells in the 6.0 T, 8.0 T, and 10.0 T groups were lower than the sham exposure control group, indicating a restraint of the growth of neural stem cells. The rate of neuron-specific enolase-positive neurons revealed by flow cytometry in HPEMS groups was the same as that in control group (P>0.05). It was suggested that 0.1 Hz, 5 pulses stimulation of HPEMS within certain scale of intensity (0.5-10.0 T), significantly promoted the growth of neural stem cells with the rational intensity being 4.0 T.
