Objective To explore the influence of acupuncture point massage combined with limb function exercise on ankle brachial index (ABI) and pulse wave velocity (PWV) in patients with coronary heart disease (CHD). Methods According to scores by grace score scale, 180 CHD patients were divided into three groups: low risk group (n=58), moderate risk group (n=68) and high risk group (n=54). Within the three groups, the patients were divided into the experiment group and the control group by using the random digital table. The control group was treated with routine nursing intervention , while the experiment groups accepted acupuncture point massage and limb function exercise training on the basis of control groups. We collected the values of ABI and PWV at four points-in-time: before intervention, 7 days after intervention, 30 days after intervention and 90 days after intervention. Results Repeated measurement data analysis of the experiment group and control group suggested that:in the moderate and high risk groups, there was statistically significant difference (P<0.05) in the data at the four time points. There was no statistically significant difference (P > 0.05) in time and group interaction effect. The difference between the experiment group and control group was statistically significant (P<0.05). Repeated measurement data analysis showed that there was no statistically significant difference (P>0.05) in ABI&PWV interaction effect at the four time points between the experiment group and control group. In the low-risk group,the differences in time points compared with the main effect were insignificant (all P>0.05). In comparison of main effect at all the four time points, there was significant different in the moderate and high risk group (P<0.05), And it suggested that time and group interaction, namely effect of time factor (1 d, 7 d, 30 d, 90 d), was not decided by the division of groups. In comparison of main effect, the difference was statistically significant (all P < 0.01) in the moderate and high-risk group, which indicated the main effect (intervention) playing main role. However, there was no statistically significant difference (P>0.05) of ABI&PWV before and 90-days after intervention. Conclusion Acupuncture point massage combined with limb function exercise can effectively improve the peripheral artery blood supply in CHD patients, lower ABI and promote PWV.

Objective:To construct the post competency evaluation index system for Da Vinci robot specialist nurses based on onion model, so as to provide references for the training and evaluation of Da Vinci robot specialist nurses in China.Methods:From August to September 2022, using the "onion model" as the theoretical framework, a preliminary draft of the index system was developed using domestic and foreign literature review, semi-structured interviews and group discussions. The Delphi method was applied to 22 nursing experts in the relevant fields to conduct two rounds of expert correspondence, screen and modify the items, and calculate the weight using the analytic hierarchy process. Finally, the post competency index system for Da Vinci robot specialist nurses based on the onion model was formed.Results:Two rounds of expert correspondence were conducted. The positive coefficient of experts was 90.91% (20/22) in the first round and 100.00% (20/20) in the second round, the coefficient of expert authority was 0.840 and 0.873, and the Kendall's coordination coefficient was 0.181 and 0.324 ( P<0.01), respectively. The final post competency evaluation index system for Da Vinci robot specialist nurses consisted of 4 first-level indicators, 14 second-level indicators and 58 third-level indicators. Conclusions:This study constructs a comprehensive post competency evaluation index system for Da Vinci robot specialist nurses based on onion model, with high expert enthusiasm and authority. It can provide references for the training and evaluation of Da Vinci robot specialist nurses in China.
