Objective To study the expression of IL-6 and IL-8 in the lung injuries induced by blunt chest trauma under the closure and open state of glottis.Methods The expressions of IL-6 and IL-8 mRNA were detected by RT-PCR in injuried lung tis-sues under the closed and open glottis states snd the control lung tissues at designed different time points.Results The expressions of IL-6 and IL-8 mRNA at 4,8,12h in the closed glottis group were obviously higher than those in the open glttis group (P <0.05) and the expressions at designed various time points in the injured lung tissue were higher than those in the control lung tissues (P <0.05).The change rule of IL-6 and IL-8 mRNA expression in the control group,closed glottis group and open glottis group was similar,the expression was up-regulated.Conclusion IL-6 and IL-8 might play an important role in the occurrence and develop-ment of functional lesion in the injured lung by blunt chest trauma.

Objective To evaluate the performance of axial-pattern composite tissue flap in the repair of skin defects after lip cancer resection.Methods From July 2012 to December 2017,8 patients with lip cancer were enrolled from Department of Dermatology,the Second Hospital of Jilin University.After lip tumor resection,the full-thickness defects were as long as 1/3 to 1/2 length of the lip,and were repaired with axial-pattern composite tissue flaps based on labial arteries.Results All the axial-pattern composite tissue flaps survived after the surgery.During the follow-up of 6 months to 5 years,no tumor recurrence was observed in the 8 patients,the shape and function of lips were improved,and the patients were satisfied.Conclusion Skin defects after lip cancer surgery can be repaired with axial-pattern composite tissue flaps based on labial arteries,which can restore the anatomical structure and aesthetic function of the lip well.
