Effects of electroacupuncture at Neiguan (PC6) on arrhythmia during myocardial infarction in a rat model of myocardial ischemia-reperfusion / 针灸推拿医学（英文版）

Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.

Analysis of influencing factors of cardiac rehabilitation information needs of patients after PCI / 中国实用护理杂志

Objective:To investigate the information demand level and its influencing factors of cardiac rehabilitation in patients after PCI, in order to provide scientific basis for doctors and nurses to formulate cardiac rehabilitation intervention strategies.Methods:A total of 146 patients after PCI were investigated with general data questionnaire and Cardiac Rehabilitation Inventory in the First Affiliated Hospital of Dalian Medical University from December 2019 to February 2020, and multiple linear regression was used to analyze the influencing factors of cardiac rehabilitation information demand.Results:The average scores of each dimension of Cardiac Rehabilitation Inventory after PCI were autonomy, process anxiety and result anxiety from high to low. Multiple linear regression showed that occupational type was a significant predictor of autonomy of patients after PCI, which could explain 4.6% of the variation of autonomy, and autonomy of in-service patients after PCI was higher than that of retirees ( t=2.81, P<0.05). Sex and age were significant predictors of process anxiety of patients after PCI, which could explain the variation of 8.6% of process anxiety. The occupational type, the medical insurance type and whether they had received professional rehabilitation guidance during hospitalization were significant predictors of anxiety after PCI, which could explain the 15.2% variation of anxiety, and the anxiety of in-service patients after PCI was lower than that of retirees ( t=-3.76, P<0.05). Conclusions:The level of cardiac rehabilitation information needs of patients after PCI is worthy of attention. Medical staff can give targeted, personalized and different forms of cardiac rehabilitation in the process of cardiac rehabilitation, and emphasize the implementation of health education and guidance for their cardiac rehabilitation in order to meet their cardiac rehabilitation information needs, improve their autonomy and alleviate their anxiety.

Effects of electroacupuncture at different time during reperfusion on the expression of Bcl-2 and Beclin1 in myocardial tissue in rats with myocardial ischemia reperfusion injury / 中国针灸

OBJECTIVE@#To compare the effects of electroacupuncture (EA) at different time during reperfusion on the expression of autophagy-related protein Bcl-2 and Beclin1 in myocardial tissue in rats with myocardial ischemia reperfusion injury (MIRI), and to explore the autophagy-related mechanism of EA on protecting MIRI.@*METHODS@#A total of 72 SD rats were randomly divided into a sham operation group, a model group, a RA group, a RB group, a RC group and a RD group, 12 rats in each group. Except the sham operation group, the rats in the remaining groups were treated with ligating the left anterior descending artery (LAD) for 30 minutes followed by reperfusion to establish the model of MIRI. The rats in the sham operation group were treated with crossing a line through the LAD. The rats in the model group did not receive treatment. The rats in the RA group, RB group, RC group and RD group were treated with EA at "Neiguan" (PC 6) for 20 min, starting at 0 h, 0.5 h, 1 h, 2 h after reperfusion. Evans Blue-TTC double-staining was employed to evaluate myocardial infarct size; the serum CK-MB was detected by ELISA and the expression of Bcl-2 and Beclin1 protein in myocardial tissue were detected by Western blot.@*RESULTS@#Compared with the model group, the percentage of myocardial infarct size in the RB group, RC group and RD group was decreased significantly (all 0.05); the increasing of Bcl-2 in the RB group was more significant than that in RC group (0.05).@*CONCLUSION@#EA at different time during reperfusion could reduce myocardial infarct size in rats with MIRI, and EA at 0.5 h after reperfusion has best efficacy; this protective effect may be achieved by increasing Bcl-2 expression and reducing Beclin1 expression to inhibit overautophagy during reperfusion.

An autophagic mechanism study on effect of electroacupuncture at different times pretreating myocardial ischemia-reperfusion injury / 中国针灸

OBJECTIVE@#To investigate the difference of protective effect of electroacupuncture (EA) at different times pretreating myocardial ischemia-reperfusion injury (MIRI) and the protein expressions of ULK1 and Beclin-1 in myocardial tissue, so as to explore the relation of the difference and autophagic mechanism.@*METHODS@#Sixty-three male SD rats were randomized into 7 groups, a sham group, a model group, an EA pretreating for 1 d (EA-1d) group, an EA pretreating for 2 d (EA-2d) group, an EA pretreating for 3 d (EA-3d) group, an EA pretreating for 4 d (EA-4d) group, an EA pretreating for 5 d (EA-5d) group, 9 rats in each group. All the rats in the pretreating groups were treated with EA 1-5 days before MIRI surgery. EA (2 Hz/100 Hz, 2 mA) was used at bilateral "Neiguan (PC 6)" for 20 min. All the rats except for those in the sham group was underwent left thoracotomy and ligation of the left anterior descending (LAD) coronary artery for 30 minutes followed by 4 hours of reperfusion to establish the MIRI model. The same operation was performed in the sham group except for the ligation of the LAD. Throughout the experiment, electrocardiogram was continuously monitored. The myocardial infarct sizes were assessed by Evans blue and triphenyltetrazolium chloride (TTC) staining. The serum concentrations of cardiac troponinⅠ(cTnⅠ) was detected by ELISA. The expressions of ULK1 and Beclin-1 in the heart tissues were analyze by Western blot.@*RESULTS@#Compared with the sham group, the concentrations of cTnⅠ and the protein expressions of ULK1 and Beclin-1 increased in the model group (all <0.05). Compared with the model group, the infarct sizes decreased in the EA-1d, EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05), with less risk sizes in the EA-3d, EA-4d and EA-5d groups (all <0.05). The levels of cTnⅠin the EA-4d and EA-5d groups decreased ( both <0.05); the expressions of ULK1 protein decreased in the EA-1d, EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05); the expressions of Beclin-1 protein decreased in the EA-2d, EA-3d, EA-4d and EA-5d groups (all <0.05). The infarct sizes in the EA-4d and EA-5d groups were lower than that in the EA-1d group (both 0.05). The cTnⅠconcentration in the EA-4d group was less than that in the EA-1d group (<0.05).@*CONCLUSION@#Pretreatment with EA for 1-5 days can improve the infarct size in MIRI, with better effect of the pretreatment for 4-5 days. The cardioprotective effect may be related to the inhibition of autophagy. But the difference of the protective effects is not related to the protein expressions of ULK1 and Beclin-1.
