The expression of phosphorylated epidermal growth factor receptor(p-EGFR),mucin 5AC(MUC5AC) protein production and gene expression were detected by Western blot,ELISA and RT-PCR respectively.Results Significant increasing of p-EGFR protein production in scrambled ODNs transfected cells with elevation of MUC5AC protein production and mRNA expression was recorded and TNF-? and CSE co-incubated groups were much higher than single TNF-? or CSE stimulated group(P

Objective To explore the mutual effect of proinflammatory factor tumor necrosis factor (TNF)-α and cigarette smoke extract(CSE) in the induction of mucin 5AC in BEAS-2B human airway epithelial cells. Methods The BEAS-2B cells were transfected with nuclear factor(NF)-κB decoy oligonucleotides(ODNs) or transfected with NF-κB scrambled ODNs as negative control,then treated with TNF-α,CSE,and TNF-α plus CSE, respectively. The expression of phosphorylated epidermal growth factor receptor (p-EGFR) , mucin 5AC( MUC5AC) protein produc-tion and gene expression were detected by Western blot, ELISA and RT-PCR respectively. Results Significant in-creasing of p-EGFR protein production in scrambled ODNs transfected cells with elevation of MUC5AC protein production and mRNA expression was recorded and TNF-α and CSE co-incubated groups were much higher than single TNF-α or CSE stimulated group(P <0. 05). In NF-κB decoy ODNs transfected cells,TNF-α stimuli revealed an obvious reduction of MUC5AC protein production and gene expression. Conclusion TNF-α and CSE can syner-gistically induce mucin 5AC expression in BEAS-2B cells, transcription factor NF-κB plays a critical role in TNF-α induced mucin production but not as so important in mucin production by CSE stimulated cells.

Objective To investigate the application of noninvasive correction of congenital auricle defor-mity,and to analyze the cure rate and the causes of incidence of complications. Methods From January 2015 to December 2016,33 patients with unilateral or bilateral congenital auricle deformities were treated with non-surgi-cal correction technique in the Plastic Surgery Department of Guangzhou General Hospital. When the treatment was completed,the VAS score was used to assess the satisfaction of the patient's parents. Results From January 2015 to December 2016,33 patients(53 ears)received noninvasive treatment of the ear deformity correction system. The average age of the patients was(63.5 ± 41.3)days,the average treatment time was(41.6 ± 15.4)days,and the average parental satisfaction was 3.76 ± 0.93(total score:5 points). Significant difference was observedin auri-cle morphology data between pre- and post- treatment ,except for cranioauricular angle(P < 0.05). Conclusions In this study,the cure rate for non-surgical correction was good,however,the satisfaction of treatment decreased with age.The most common complication of treatment was auricle skin damage. The reasons of causing complica-tions maybe the age-induced reduction of ear cartilage elasticity which brought great pressure on the ear ,and the increase of the treatment time.

Three-parent test tube baby technology is important to solve the mitochondrial genetic disease.Once available,it raises greatly ethical controversy such as breaking traditional family values,hitting the religious belief,existing unknown risks,correctly handling the failed embryo,as well as the influence on the social status of the babies.Regarding these controversy,we can discuss it from several aspects.Because the development of ethics is behind the progress of science and technology,we should affirm the value of three-parent test tube baby technology and balance the development of science and technology with respecting the religious beliefs.Strict supervision system and standard application system reflect our respect for life.Incomprehension to the unknown things should become the motivation of our inquiry.We should face up to our fear of three-parent test tube baby technology,and thus to strengthen research and deepen understanding.Based on the above argument,this paper puts forward the ethical principles that should be followed in the development of three-parent test tube baby technology,namely respect,benefit,no harm and justice.
