Objective The present study was aimed at developing a circumferential phototherapy unit using 3M reflective materials in the double-sided phototherapy unit and investigating its efficacy in treating neonatal hyperbilirubinemia.
Study Design Forty-two infants with neonatal hyperbilirubinemia were selected from our hospital; they were randomly divided into control (n = 21) and experimental groups (n = 21). The experimental group was treated with the circumferential phototherapy unit, while the control group was treated with an ordinary phototherapy unit.
Results No significant differences were noted between the two groups in the levels of transcutaneous bilirubin before phototherapy (p > 0.05). After 12 hours of phototherapy, the value of transcutaneous bilirubin decreased significantly in the experimental group compared with that of the control group (p < 0.05). Additionally, the two groups did not exhibit any significant difference in the side effects (p > 0.05).
Conclusion Our results indicated that the circumferential phototherapy unit was more effective than the ordinary phototherapy unit in treating neonatal hyperbilirubinemia.
Key Points
Neonatal hypoxic ischemic encephalopathy (HIE) is mainly resulted from perinatal asphyxia, which can be repaired by NSCs. miR-204-5p is claimed to impact the activity NSCs. Our research will probe the miR-204-5p function in oxygen-glucose deprivation (OGD)-treated NSCs. miR-204-5p level
was enhanced and WNT2 level was reduced in HIE rats. Rat NSCs were stimulated with OGD condition under the managing of mimic or inhibitor of miR-204-5p. The declined cell viability, enhanced apoptosis, downregulated Tuj1 and GFAP levels, and shortened total neurite length were observed in
OGD-treated NSCs, which were further aggravated by the mimic and rescued by the inhibitor of miR-204-5p. Furthermore, the inactivated WNT2 and Ephrin-A2/EphA7 signaling pathway in OGD-stimulated NSCs was further repressed by the mimic and rescued by the inhibitor of miR-204-5p. In addition,
WNT2 was confirmed as the targeting of miR-204-5p. Lastly, the function of miR-204-5p mimic on the proliferation, apoptosis, differentiation, WNT2 and Ephrin-A2/EphA7 signaling pathway in OGD-stimulated NSCs was abolished by HLY78, an activator of Wnt signaling. Collectively, miR-204-5p repressed
the growth and differentiation of fetal NSCs by targeting WNT2 to regulate the Ephrin-A2/EphA7 pathway.
