Construction of an intervention program for diabetic retinopathy patients undergoing surgery based on the theory of'Timing It Right' / 中华护理杂志

Objective To construct an intervention program for diabetic retinopathy(DR)patients undergoing surgery based on the theory of'Timing It Right'.Methods Guided by the theory of'Timing It Right',based on literature review and semi-structured interview,the first draft of the intervention program was formulated.From December 2022 to February 2023,15 medical and nursing experts in ophthalmology and endocrinology from 5 provinces(cities)in Zhejiang,Sichuan,Shanxi,Chongqing and Shanghai were interviewed by Delphi expert for 2 rounds to seek their advice and revision,and the final draft was formed.Results The effective recovery rate of 2 rounds of expert consultations was 93.75％and 100％.The authority coefficients were 0.87.The importance and feasibility of Kendall'W coordination coefficients were 0.325,0.138 and 0.193,0.141 in 2 rounds,respectively(P＜0.001).The finalized intervention program consisted of 6 months,which included 5 first-level items,18 second-level items and 43 third-level items.Conclusion The intervention program for DR patients undergoing surgery based on the theory of'Timing It Right'is reliable,scientific,feasible and practical,and it can meet the needs of such patients,providing a reference for improving their self-management ability,improving their negative emotions and delaying disease progression.

p38 MAPK antisense oligodeoxynucleotide inhibited up-regulation ofGLT-1 during induction of brain ischemic tolerance induced bycerebral ischemic preconditioning / 中国药理学通报

Aim To investigate the effect of p38 MAPK AS-ODNs on the expression of GLT-1 during the induction of brain ischemic tolerance induced by cerebral ischemic preconditioning (CIP).Methods Eighty healthy male Wistar rats with permanent occlusion of the bilateral vertebral arteries were randomly divided into 6 groups: ①Sham group (n=10);②CIP group (n=10);③ischemic insult (Ⅱ) group (n=10);④CIP+Ⅱ group (n=10);⑤p38 MAPK AS-ODNs+CIP+Ⅱ group (n=30);⑥p38 MAPK S-ODNs+CIP+Ⅱ group (n=10).Group ⑤ was divided into 5 nmol, 10 nmol and 15 nmol subgroups according to the dose of p38 MAPK AS-ODNs (n=10).The dose of p38 MAPK S-ODNs was 15 nmol.All the rats were sacrificed 6 h and 2 d after the sham operation or the last time of global brain ischemia reperfusion.Western blot and immunohistochemistry analysis were used for detecting the expression of p-p38 MAPK and GLT-1 protein.Results CIP moderately up-regulated the expression of p-p38 MAPK and significantly up-regulated the expression of GLT-1 protein, inhibited the excessively up-regulation of p-p38 MAPK and the down-regulation of GLT-1 induced by ischemic insult.p38 MAPK AS-ODNs significantly inhibited the up-regulation of p-p38 MAPK and GLT-1 protein in a dose-dependent manner during the induction of brain ischemic tolerance by CIP.Conclusion p38 MAPK AS-ODNs inhibit the up-regulation of GLT-1 during the induction of brain ischemic tolerance induced by CIP.
