Objective To establish the standard paths of creative expression cognitive intervention program for Chinese older adults with mild cognitive impairment(MCI).Methods Thirty MCI older adults received creative expression cognitive program twice per week for six weeks.The action research process was implemented through plan,action,observation and reflection to constantly modify and improve the paths.The Montreal cognitive assessment scale(MoCA),daily living activity scale(ADL),self-made creative story-telling therapy activity observation table and feedback form were used to evaluate the effects of program.Results The standard paths of the creative expression cognitive intervention program for Chinese older adults with MCI were established through the action research method.There were no significant differences in MoCA and ADL before and after intervention(P＞0.05).The attending intention,attention,expression ability,communication skills,participant levels,enjoyment had been significantly improved through this program (P＜0.05).Patients believed that the creative storytelling was able to stimulate their creativity and expression ability,help them attain more social support and trust,thus they would be more willing to involve and cooperate in developing group activities.Conclusion The creative expression cognitive intervention activity is an effective and feasible non-pharmacological treatment for Chinese older adults with MCI.It provides an economical,convenient,easy to implement,and higher participatory nursing suitable technology for elderly service industry.

Objective:To observe the status of the sinus membrane using fiber optic endoscope during the lateral window approach sinus floor elevation to provide a reference for clinicians when evelvating the sinus mucoperiosteum.Methods:Sixty-six patients (72 sides) who underwent maxillary sinus floor elevation in Beijing Ruicheng Stomatology Hospital from September 2016 to December 2019 were selected, including 40 males and 26 females, aged 26-80 years old [(56.2±11.5) years]. And fiber optic endoscopy was used to observe the maxillary mucoperiosteum during the operation.Results:The status of maxillary sinus mucoperiosteal during lateral window approach sinus floor elevation can be divided into four categories: ① Class Ⅰ, complete periosteal, no damage to mucoperiosteum; ②Class Ⅱ, periosteal injury, unexposed laminae propria; ③Class Ⅲ, periosteal Rupture, exposed lamina propria; ④ Class Ⅳ, mucoperiosteum perforation, rupture of periosteum, lamina propria and epithelial layer. A total of 72 operations were performed, including 18 cases of class I, 28 cases of class Ⅱ, 4 cases of class Ⅲ, and 22 cases of class Ⅳ.Conclusions:The status of maxillary sinus mucoperiosteal during lateral window approach sinus floor elevation can be divided into four categories. Fiberoptic endoscopy as a clinical auxiliary examination method can improve the operator′s control of the status of the maxillary sinus membrane and assist the peeling of the mucosa.
