BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

All were males, aged 32-58 years [(46.9±8.7)years]. Acute injury was found in 1 patient and chronic injuries in 7 patients, including 3 with cervicothoracic kyphotic deformity and 5 with thoracolumbar kyphotic deformity. Five patients were complicated by odontoid fractures, 1 by C 2-C 3 fracture and 2 by atlantoaxial dislocation. According to American Spinal Injury Association (ASIA) scale, 2 patients were with grade C, 3 with grade D, and 3 with grade E. The patients were treated with posterior upper cervical reduction and fixation combined with cervicothoracic PSO or thoracolumbar PSO respectively according to the location of the deformity. The operation time and intraoperative blood loss were recorded. Neck disability index (NDI), visual analogue scale (VAS), C 0-C 2 angle, C 1-C 2 angle, cervical lordosis angle (CL), head tilt angle (HT), chin-brow vertical angle (CBVA), cervical sagittal vertical axis (CSVA), and sagittal vertical axis (SVA) were compared before surgery, at 1 week and 3, 6, 12 months after surgery, and at the last follow-up. The healing of fractures and fusion of osteotomy site were recorded at 12 months after surgery. Recovery of neurological function was observed at the last follow-up. Incidence of complications was observed. Results:Patients were all followed up for 12-24 months [(17.0±5.4)months]. The operation time was 5.5-7.2 hours [(6.2±0.6)hours] and the intraoperative blood loss was 480-800 ml [(629.4±124.0)ml]. The NDI scores at 1 week and 3, 6, 12 months after surgery, and at the last follow-up were (14.6±2.6)points, (13.6±2.8)points, (12.8±2.4)points, (12.8±2.7)points, and (12.8±2.6)points respectively, significantly lower than (29.6±8.5)points preoperatively ( P<0.01). There were no significant differences in NDI scores at various time points after surgery ( P>0.05). The VAS scores were 2.0(1.0, 3.0)points, 1.5(1.0, 2.0)points, 0.5(0.0, 1.8)points, 0.5(0.0, 1.7)points, and 0.5(0.0, 1.8)points respectively, significantly lower than 3.5(3.0, 4.8)points preoperatively ( P<0.01). The VAS score at 3 months postoperatively was lower than that at 1 week postoperatively ( P<0.05), and the VAS score at 6 months postoperatively was lower than that at 3 months postoperatively ( P<0.05). There were no statistically significant differences in VAS scores at 6, 12 months postoperatively, and at the last follow-up ( P>0.05). There were no statistically significant differences between C 0-C 2 angle and C 1-C 2 angle preoperatively and at different time points postoperatively ( P>0.05). At 1 week and 3, 6, 12 months postoperatively and at the last follow-up, the CL values were -8.5(-5.3, -11.9)°, -8.6(-5.5, -11.9)°, -8.4(5.2, -12.1)°, -8.8(-5.6, -12.4)°, and -8.7(-5.3, -12.5)° respectively, significantly higher than 1.2(9.5, -4.8)° preoperatively ( P<0.01); the HT values were 6.1(4.5, 9.6)°, 6.1(4.3, 9.4)°, 6.0(4.2, 8.9)°, 6.0(4.2, 9.2)°, and 6.1(4.3, 9.2)° respectively, significantly lower than 17.0(10.3, 22.0)° preoperatively ( P<0.01); the CBVA values were (23.2±5.0)°, (23.1±4.8)°, (23.0±4.7)°, (23.1±4.7)°, and (23.1±4.9)° respectively, significantly lower than (44.1±9.8)° preoperatively ( P<0.01); the CSVA values were 5.2(4.2, 7.5)cm, 5.4(4.1, 7.1)cm, 4.7(4.0, 7.4)cm, 5.4(4.1, 7.0)cm, and 5.1(4.3, 6.5)cm respectively, significantly shorter than 9.0(7.8, 9.3)cm preoperatively ( P<0.01); the SVA values were 7.7(6.2, 13.7)cm, 7.5(6.0, 13.4)cm, 7.6(6.2, 13.2)cm, 7.4(6.3, 13.1)cm, and 7.5(6.2, 13.2)cm respectively, significantly shorter than 16.8(8.2, 27.2)cm preoperatively ( P<0.05). There were no statistically significant differences among CL, HT, CBVA, CSVA, and SVA values at different time points after surgery ( P>0.05). All the fractures healed at 12 months after surgery and Bridwell grade I healing was achieved at all the osteotomy sites. At the last follow-up, all the patients were classified as ASIA grade E, significantly improved compared with preoperatively ( P<0.01). One patient had transient C 8 nerve paralysis after surgery and recovered after 4 weeks′ treatment. The remaining patients did not develop any infection or internal fixation-related complications, such as broken rods, broken screws, or loose screws. Conclusion:For AS kyphosis deformity complicated with upper cervical injury, posterior reduction and fixation combined with cervicothoracic or thoracolumbar PSO can effectively promote functional recovery, relieve pain, maintain overall trunk balance, improve neurological symptoms, and reduce the incidence of complications.
