Cervical spondylosis is due to degenerative cervical disc and its stimulation or oppression of the adjacent nerves, spinal cord, spinal artery and other tissue caused by clinical symptoms. The cervical spine is an anatomical structure with activity, while the pillow has a certain plastic fixation effect on the cervical spine anatomy. Therefore, the pillow not only plays a health role in the cervical spine, but also plays an important role in restoring the normal physiological curvature of the cervical spine. Based on this, a multi-functional cervical vertebra treatment pillow is designed, which not only has the functions of traction, maintaining different positions of the cervical spine, correcting the cervical curvature and equipment exercises, but also has the functions of voice broadcast and network data terminal.

Objective To study the variability of oxygen saturation in intestinal tissue of preterm infants during erythrocyte infusion .Method Preterm infants aged over 5 days, hospitalized in our NICU from March 2016 to August 2016 were selected by computer random number generator . Near-infrared spectroscopy was applied to monitor splanchnic tissue oxygen saturation ( SrSO2 ) and cerebral tissue oxygen saturation(CrSO2)during erythrocyte transfusion.The duration of transfusion was 4 hours.The mean value and range of SrSO2 and CrSO2 during transfusion were analyzed.To analysis the average and variable range of SrSO2 and CrSO2 and to illuminate the correlation with post-conceptional age. Result A total of 34 premature infants were collected.The average of SrSO2 was (0.56 ±0.06) and the average of CrSO2 was (0.62 ±0.02) throughout transfusion, There was a significantly greater change in SrSO2 than in CrSO2 during the transfusion period (0.35 ±0.14 vs.0.18 ±0.09) (P<0.05).The changing range of CrSO2 was smaller as the post-conceptional age increased , and was significant different statistically ( P=0.006). While there was little change in the range of SrSO 2 (P=0.191).Conclusion The of SrSO2 change was more significant than CrSO 2 in preterm infants during erythrocyte transfusion , which may cause ischemia-reperfusion injury to the intestinal tissue .It should be more cautious to avoid transfusion-related necrotizing enterocolitis.

Objective To explore the impact of early repetitive painful procedures on subsequent pain behaviors and physiological indicators in full-term infants.Methods Sixty-two full-term neonates were enrolled (male 36 cases,female 26 cases) from the medical center of neonatal care at Nanjing Children's Hospital Affiliated to Nanjing Medical University from March to May in 2009.The data of all painful procedures were performed on those neonates and their responses to them were collected by using digital video recording were collected.The Neonatal Facial Coding System C(NFCS) and Neonatal Infant Pain Scale(NIPS) were used prospectively to evaluate the pain response to painful procedures.Results The average experience of pain caused by operation on newborn at the hospital was 56.5 times (12-249 times),and the daily average was 5.9 times (4-26 times).After they were exposed to more than 10 repetitive pain procedures,the full-term neonates showed the declining pain response assessed by NFCS and NIPS during the subsequent painful procedures (NFCS:P10=0.012,P20=0.015,P30=0.041;NIPS:P10=0.006,P20=0.015,P30=0.049),and the temporarily enhanced pain response was observed in the preparation phase of the subsequent painful procedures (NFCS:P2＜0.001,P3＜0.001,P4=0.004,P5=0.009;NIPS:P2＜0.001,P3＜0.001,P4=0.045,P5 =0.031).Bnt there was no difference in preparation phase.There was no alternation in latency and crying time after repetitiing painful procedures,but the proportion of crying neonates in the preparation phase of the painful procedures was increased(P=0.032).Conclusions After exposed to repetitive pain,full-term neonates expressed hypoalgesia during subsequent painful procedures,but the temporary irritation was enhanced during the following phases exposed to stress.
