OBJECTIVE: To observe the effect of electroacupuncture (EA) pretreatment of "biaoben acupoint combination" on cardiomyocyte mitochondrial fission in the rats with myocardial ischemia-reperfusion injury (MIRI) and explore its mechanism. METHODS: Fifty male SD rats were randomly divided into a sham-operation group, a model group, an EA pretreatment group, an EA pretreatment + Compound C group and an EA pretreatment+ML385 group, 10 rats in each group. In the EA pretreatment, the EA pretreatment + Compound C group and the EA pretreatment+ML385 group, EA was delivered at bilateral "Neiguan" (PC6), "Zusanli" (ST36) and "Guanyuan" (CV4) for 20 min, with continuous wave and 2 Hz of frequency, 1 mA of current, once daily for consecutive 7 days. On day 8, in the EA pretreatment + Compound C group and the EA pretreatment+ML385 group, 30 min before model preparation, the intraperitoneal injection with Compound C (0.3 mg/kg) and ML385 (30 mg/kg) was administered respectively. Except in the sham-operation group, the ligation of the left anterior descending coronary artery was performed to prepare MIRI rat model in the rest groups. In the sham-operation group, the thread was not ligated. After modeling, the content of reactive oxygen species (ROS) in the ischemic area was measured by flow cytometry, superoxide dismutase (SOD) was detected using xanthine oxidase method, and malondialdelyde (MDA) was detected using thiobarbituric acid (TBA) chromatometry. The morphology of myocardial tissue in the ischemic area was observed with HE staining, and the mitochondria ultrastructure of cardiomyocytes observed under transmission electron microscopy. Using immunofluorescence analysis, the positive expression of mitochondrial fission factor (MFF), mitochondrial fission 1 protein antibody (Fis1) and dynamin-related protein 1 (Drp1) was detected; and with immunohistochemical method used, the protein expression of adenosine monophosphate-activated protein kinase (AMPK), nuclear factor E2-associated factor2 (Nrf2) and Drp1 in the ischemic area was detected. RESULTS: Compared with the sham-operation group, the content of ROS and MDA in the myocardial tissue of the ischemic area, and the positive expression of MFF, Fis1 and Drp1 increased in the model group (P<0.01); the content of SOD and the protein expression of AMRK and Nrf2 decreased (P<0.01), and the protein expression of Drp1 elevated (P<0.01). Compared with the model group, the content of ROS and MDA in the myocardial tissue of the ischemic area, and the positive expression of MFF, Fis1 and Drp1 were dropped in the EA pretreatment group (P<0.01); the content of SOD and the protein expression of AMRK and Nrf2 rose (P<0.01), and the protein expression of Drp1 declined (P<0.01); and in the EA pretreatment+Compound C group and the EA pretreatment+ML385 group, the positive expression of MFF, Fis1 and Drp1, and the protein expression of Drp1 were all reduced (P<0.01). When compared with the EA pretreatment + Compound C group and the EA pretreatment+ML385 group, the content of ROS and MDA in the myocardial tissue of the ischemic area, and the positive expression of MFF, Fis1 and Drp1 were dropped in the EA pretreatment group (P<0.01); the content of SOD and the protein expression of AMRK and Nrf2 rose (P<0.01, P<0.05), and the protein expression of Drp1 decreased (P<0.05). In comparison with the model group, the EA pretreatment+Compound C group and the EA pretreatment+ML385 group, the cardiac muscle fiber rupture, cell swelling and mitochondrial disorders were obviously alleviated in the EA pretreatment group. The morphological changes were similar among the model group, the EA pretreatment+Compound C group and the EA pretreatment+ML385 group. CONCLUSION Electroacupuncture pretreatment of "biaoben acupoint combination" attenuates myocardial injury in MIRI rats, probably through promoting the phosphorylation of AMPK and Nrf2, inhibiting the excessive mitochondrial fission induced by Drp1, and reducing mitochondrial dysfunction caused by mitochondrial fragmentation and vacuolation.

Objective: To explore the effects of group sports game intervention on social ability and quality of life of children with austism spectrum disorders (ASD),so as to provide reference for rehabilitation intervention of social and quality of life of children with ASD. Methods: From September 2021 to January 2022, 72 children with ASD aged 4-6 in the children s rehabilitation department of Xiangyang Central Hospital were selected to participate in the study, and were randomly divided into experimental group ( n =36) and control group ( n =36). The control group received routine rehabilitation training (including individual sports game training), and the experimental group replaced individual sports game training with group sports game training on the basis of routine rehabilitation.The course content mainly included three parts: warm up before class, group sports games and relaxation after class. The course combined social skills with sports games, and was carried out in a group form (divided into 12 groups with 3 people in each group), and was trained five times a week for 60 minutes, for a total of 12 weeks. The scores of Childhood Autism Rating Scale (CARS), Autism Treatment Evaluation Checklist (ATEC), Social Responsiveness Scale (SRS) and Pediatric Quality of Life Inventory Version 4.0 Generic Core Scales (PedsQL 4.0) were observed before and after treatment. t-test and χ 2 test were used for statistical analysis. Results: There was no significant difference in SRS scores between the experimental group and the control group before intervention ( t =-0.63, P >0.05). After the intervention, the total response rate in the experimental group was 83.33 %, higher than 41.67% in the control group χ 2=13.33, P <0.05),and the SRS scores decreased in the experimental group and control group ( t =17.75,8.71, P <0.05). The SRS scale score of the experimental group Social perception (17.67±4.12) , social cognition (30.33±4.99) , social communication (50.33±9.39) , social motivation (24.25±6.78) scores and total scores ( 152.67± 25.82) were lower than those of the control group(22.17±5.34，36.00±4.13，62.58±11.07，34.42±7.13，186.33±29.03)( t = -4.88，-2.03，-2.13，-3.58，-3.01， P ＜0.05).After the intervention, the scores of social function (53.33±18.01) and total score (283.83±51.83) on PedsQL 4.0 scale in experimental group were higher than those in control group(23.33±15.13，218.00±39.01) ( t =4.42，3.52， P ＜0.05). After the intervention, Autism Treatment Evaluation Scale (ATEC) scores of experimental groups(44.33±14.72) was lower than that in control group ( 59.33±16.95)( t =-2.32, P ＜0.05). Conclusion The intervention of group sports game has a significant effect on improving social ability and life quality of children with ASD.
