Myocardial ischemia-reperfusion injury （MIRI） is a key complication of reperfusion therapy for ischemic heart disease. Due to its complex pathological mechanism， there is still a lack of targeted drugs and effective interventions in clinical practice. As the core organelle of cell energy metabolism， mitochondria not only undertake the key function of adenosine triphosphate （ATP） synthesis， but also maintain the homeostasis of intracellular environment by regulating ion dynamic balance， oxidative stress response and apoptosis. Mitophagy is an important mechanism to regulate mitochondrial homeostasis. Phosphatase and tensin homolog （PTEN）-induced putative kinase 1 （PINK1）/Parkin signaling pathway， as one of its core pathways， has been proved to have important physiological functions. Mitophagy mediated by PINK1/Parkin signaling pathway can synergistically act on the pathological process of MIRI through the multi-level regulatory mechanism of oxidative stress， calcium homeostasis imbalance and ferroptosis， so as to achieve the prevention and treatment of MIRI by reducing mitochondrial dysfunction and inhibiting programmed cell death. Studies have shown that modern drugs， such as proprotein convertase subtilisin/kexin type 9 （PCSK9） inhibitors， DL-3-n-butylphenylpeptide， and dapagliflozin， active ingredients of traditional Chinese medicine such as phenols， saponins， flavonoids， and anthraquinones， as well as traditional Chinese medicine compounds and preparations such as Tongxinluo capsules， Shuangshen Ningxin capsules， and Qili Qiangxin capsules， can exert myocardial protection by regulating mitophagy mediated by this pathway and multiple targets. This study focuses on the PINK1/Parkin pathway， aiming to provide new ideas and directions for the prevention and treatment of MIRI from the perspective of PINK1/Parkin-mediated mitophagy.

Osteoarticular diseases,common chronic degenerative disorders in the elderly,involve the gradual deterioration and degeneration of bones or joints.The metabolic capacity declines with age.Impaired bone metabolism dis-rupts homeostasis,leading to osteoarticular dysfunctions.Cuprotosis,a novel form of programmed cell death mediated by ferredoxin 1,matters for the pathologic process in osteoarticular diseases.Cuprotosis influences the levels of intercellular signal transduction to induce oxidative stress,inflammation,pyroptosis,and ferroptosis in joints.Those cell death and mi-tochondrial dysfunction ultimately exacerbate the progression of osteoarticular diseases.Therefore,this review summarizes the mechanism of copper homeostasis-cuprotosis in osteoarticular diseases and the potential applications targeting copper homeostasis-cuprotosis.

Objective To analyze the modeling and evaluation method for vascular restenosis animal models in the last 10 years,to provide a reference for improving animal models of vascular restenosis.Methods Literature related to vascular restenosis was retrieved from mainstream Chinese and English databases from 2013 to 2023.Data on experimental animal strains,modeling method,modeling cycles,and detection method were extracted from the included literature,and a database was established using Excel for summary analysis.Results Among the 122 identified articles,the main experimental animals were rats,rabbits,and pigs,and most animals were male.The most common modeling method was balloon injury,and the modeling cycle was mainly within 4～8 weeks.The main detection indexes were histopathology,accounting for 37.18％,including routine hematoxylin-eosin,Masson,and Elastica van Gieson(EVG)staining.Conclusions The translatability of porcine vascular restenosis models is currently more in line with expectations,but their cost is high and they are unpopular,and rats and rabbits thus remain the main animal models.Balloon injury is the main mode of modeling.Different animal models and modeling method for vascular restenosis have advantages and disadvantages,and the model should be selected according to the experimental purpose.Animal models of vascular restenosis still have some limitations,however,and better animal models are required in the future.

OBJECTIVE： To evaluate the literature quality of systematic reviews/Meta-analysis of oral administration of traditional Chinese medicine （TCM） in the treatment of lumbar disc herniation （LDH） using radar plot， and to provide scientific and effective evidence for clinical use of medicine. METHODS： Retrieving CNKI， VIP， Wanfang database， CBM， PubMed， Cochrane library and Embase during the establishement of database to Oct. 1st， 2018， the literatures about systematic reviews/Meta-analysis of oral administration of TCM in the treatment of LDH were collected. After data extraction of literatures met inclusion criteria， the quality literatures were evaluated from 6 aspects of radar plot （year of publication， design type， AMSTAR methodological quality evaluation， PRISMA reprot quality evaluation， homogeneous， publication bias risk）. The average score of rank number was calculated. Moreover， Excel 2010， Adobe Illustrator CC and other software were used to draw and optimize the radar plot. RESULTS： A total of 6 qualified literatures were included； average score of rank number of 6 aspects were 3.83， 4.67， 3.83， 3.67， 6.00， 4.67， scoring 4.56 in average. Multivariate evaluation of radar plot showed that 2 studies had higher qualities and only 1 study had lower qualities relatively. However， problems could be found such as information selection bias， inclusion and exclusion criteria， publication situation， limitations， project registration. CONCLUSIONS： The literature quality of systematic review/Meta-analysis of oral administration of TCM in the treatment of LDH need to be improved， starting with strengthening methodological quality and reporting quality. Radar plot is a visual and effective method of graphic evaluation， which is worth popularizing and applying in the future.

Objective To explore the correlations of the MRI findings and its pathological typing in the focal cortical dysplasia (FCD) .Methods MR images of 74 patients with FCD confirmed by operation and histopathologic examination were analysed retro‐spectively .MRI findings with FCD were divided into three subtypes including radial band type ,hyperintensity type and mild type . The correlation of the FCD MRI findings and pathological typing is analysed .Results In 74 patients with FCD ,there were radial band type in 12 cases ,hyperintensity type in 32 cases ,and mild type in 30 cases respectively .M RI finding of radial band type FCD showed a tail of increased T2WI/FLAIR signal tapering down to the lateral ventricle .Hyperintensity type FCD showed increased T2 WI/FLAIR signal in the cortex and subcortical white matter ,accompanied with focal cortical thickening .Mild type FCD showed T2 WI/FLAIR subtle hyperintense signal in cortex with or without focal cortical thickening ,but there was no hyperintense signal in subcortical white matter .Most of radial band type FCD were ⅡB in pathology .Most of hyperintensity FCD were ⅡA and ⅡB .Mild type FCD was more found to beⅠA orⅠB .Conclusion Analysing MRI features would improve the accurate diagnosis of FCD and help to infer the pathological type .

Objective To determine MR manifestations and pathologic types of benign meningiomas and their relationship with tumor recurrence.Methods There were 218 patients (160 females,58 males; age range 4-79 years) with benign meningiomas in the study,including 31 recurrent meningiomas (recurrence group)and 187 primary meningiomas (primary group).All patients were proved by postoperative pathology.Differences of pathological types and MRI manifestations between the recurrence group and the primary group were evaluated by using x2 test and rank sum test.Logistic regression analysis was performed by taking tumor recurrence as the dependent variable,and age,gender,vital structures involvement and pathologic types as independent variables.The recurrent time intervals were compared by rank sum test.Results There were 30 patients with intracranial vital structures involvement or extreintracranial communication tumors in the recurrent group,which was obviously higher than that of the primary group (61 patients).The difference was statistically significant (x2 =57.672,P =0.001).The tumors located in the skull-base and juxtasinus in the recurrent group were obviously more than those in the primary group,and difference was statistically significant (x2 =10.990,P =0.001).Multi-logistic regression analysis showed that the recurrent risk of benign meningiomas was elevated significantly only with vital structure involvement or extre-intracranial communication tumors (wald x2 =31.863,OR =3.820,P =0.001).The recurrent risk of dural sinus involvement was 3.820 times of cerebral artery trunk and cranial nerves involvement,and the risk of the latter was 3.820 times of the non-involved.There was no statistical difference between the two groups in pathology type,location,peritumoral edema,tumor morphology and tumor size.The relapse time of dural sinus involvement and cerebral artery trunk involvement in the recurrent group was 24(13 to 180) and 126(12 to 187) months,respectively.There was significant difference (Z =2.197,P =0.028).Conclusions It is more common that the recurrent benign meningiomas located in the skull base and juxtasinus.The recurrent risk significantly increases when benign meningiomas with vital intracranial structure involved or with extra-intracranial communication tumor.The relapse time of dural sinus involvement is possibly shorter than that of cerebral artery trunk involvement.MRI plays an important role in predicting tumor recurrence and prognosis of benign meningiomas.

ObjectiveTo describe the MR features of Rasmussen encephalitis (RE).Methods The MRI of 10 pathologic confirmed patients (7 male,3 female,mean age 11 ± 4 years) with RE were retrospectively analyzed in this study.Routine axial,sagittal and coronal (perpendicular to the oblique long axis of the hippocampus) scans were obtained for T1WI,T2WI and fluid-attenuated inversion recovery (FLAIR)images. The location and degree of cerebral atrophy,gray matter signal changes,and the evolution of these findings were evaluated. Results Brain atrophy included the enlargement of lateral ventricle(8/10),temporal horn (9/10)and lateral fissure (9/10); widened sulci and small gyri in the isolateral hemisphere (7/10) ; atrophy in caudate and putamen nucleus (6/10).The cortical atrophy was extensive at late stage of the RE,and usually was hemispheric or involved more than two lobes.The signal changes included hyperintensity involving extensive cortical and/or subcortical regions (9/10). The follow-up MR study demonstrated the progression of brain atrophy and extensive signal changes.Conclusions RE usually presents in pediatric patients. The imaging findings included progressive unilateral brain atrophy,enlargement of lateral ventricle,lateral fissure and sulci,and small gyri with or without cortical T2hyperintensity.Deep nucleus atrophy may be involved in RE.
