Effect of Unilateral Basal Ganglia Hemorrhage on Neurological Function in Neonatal Rats ZHOU Shao-xiong, HU Jin-ping 2021, 11 (3):  1-4.  DOI: 10.3969/j.issn.2095-1396.2021.03.001 Abstract ( 66 )   PDF (1055KB) ( 18 )   Objective：To explore the effect of unilateral basal ganglia hemorrhage on neural function in neonatal rats. Methods：Fifty four neonatal rats were randomly divided into normal control group （NC，n = 18），sham operation group （SH，n = 18） and intracerebral hemorrhage group （CH，n = 18）. 25 μL autologous blood was injected into the left caudate nucleus to establish the model of basal ganglia hemorrhage. NC group was given normal feeding without any intervention. In SH group，microinjection pump needle was inserted into the left caudate nucleus without blood injection. Other treatments were the same as those in CH group. The neurological function score at different time points，the results of daytime opening experiment and evening opening experiment were compared among the three groups. Results：After modeling，the neurological function of rats showed different degrees of damage. SH group rats had relatively mild neurological damage symptoms，which could recover in a short time，and all recovered 72 hours after operation. The changes of muscle tension and hemiplegia occurred in CH group. Compared with SH group and NC group，the neurological function score of CH group was significantly higher on the 1st and 3rd day （P<0.05）. There was no significant difference in neurological function scores between SH group and NC group on the 1st，3rd，7th and 14th day （P>0.05）.Compared with SH group and NC group，CH group had more grooming times，upright times and crossing grid times （P<0.05）. Compared with SH group and NC group，CH group had more upright times and crossing grid number （P<0.05）. Conclusion：The development of rats will appear unilateral basal ganglia focal hemorrhage injury symptoms，with compensatory，repairable and other basic characteristics，and most of them will not appear serious neuromotor dysfunction left behind，but will cause non selective attention level decreased，autonomic activity increased and other symptoms.

Neuroprotective Effect of Estrogen-Mediated Mitochondrial Pathway DAI Yue-ying, ZHAO Yu-wei, YAO Si-fan, SHEN Li-xia 2021, 11 (3):  33-42.  DOI: 10.3969/j.issn.2095-1396.2021.03.007 Abstract ( 66 )   PDF (1164KB) ( 15 )   Alzheimer’s disease（AD） is a multifactorial disease with cognitive and executive dysfunction as the main clinical manifestations. The pathogenesis of AD is Aβ cascade and abnormal tau protein，etc.. Epidemiological investigation showed that the incidence of AD in postmenopausal women was 1.5~3.0 times higher than that in men of the same age，estrogen either directly or indirectly affects mitochondria. In addition，because mitochondria are regarded as the energy body of cells and the key regulator of neuronal viability during excitotoxicity，the mitochondrial mechanism of AD has also become the research area of AD pathogenesis. Aβ can bind directly to the mitochondrial membrane，thus changing the dynamics and function of mitochondria，leading to abnormal energy metabolism，resulting in a series of chain reactions such as apoptosis. Studies have shown that mitochondrial dysfunction exacerbates Aβ deposition and tau abnormal phosphorylation，which in turn promotes mitochondrial injury and induces apoptosis through a mitochondrial dependent apoptotic pathway. This article reviews the neuroprotective effect of estrogen through mediating mitochondrial pathway in the case of AD，in order to provide some basic theoretical thinking for the prevention and treatment of AD.

Regulation of Mitochondrial Autophagy and Its Role in Cerebral Ischemia-Reperfusion Injury XIE Jia-jia, SUN Ting, ZHANG Dan-shen 2021, 11 (3):  43-49.  DOI: 10.3969/j.issn.2095-1396.2021.03.008 Abstract ( 165 )   PDF (1118KB) ( 47 )   As a regulatory mechanism involved in cell metabolism and organelle renewal，autophagy plays an important role in the physiological and pathological processes of the body. Mitophagy，as a type of cell target-specific autophagy，can identify and remove functionally impaired mitochondria and achieve mitochondrial quality control. Mitochondria mainly regulate autophagy through Parkin-dependent and non-Parkin-dependent pathways，thereby affecting the body’s function. Studies have shown that mitochondrial autophagy is closely related to the process of cerebral ischemia-reperfusion injury，but its role in cerebral ischemia-reperfusion injury has been controversial. This article mainly summarizes the mechanism of mitochondrial autophagy and the way in which mitochondrial autophagy participates in cerebral ischemia-reperfusion injury. Related Articles | Metrics

Studies on the Role of Focal Adhesion Kinase in Diseases HE Jin-zhao, YANG Bao-xue 2021, 11 (3):  50-64.  DOI: 10.3969/j.issn.2095-1396.2021.03.009 Abstract ( 167 )   PDF (1251KB) ( 43 )   Focal adhesion kinase （FAK） as a crucial component of focal adhesions （FAs） plays an important role in intracellular and extracellular signal transduction. FAK is a non-receptor tyrosine kinase and mainly regulated by integrins，growth factors and G-protein-coupled receptors，which mediates various bioactivities，such as cell migration，invasion，proliferation，differentiation and angiogenesis. A wide array of studies have demonstrated that abnormal expression and activation of FAK were critically involved in the pathogenesis of cardiovascular diseases，hepatic and renal injuries，lipometabolism，immunoregulation and cancer，in which were closely related to poor prognosis. In recent years，with the development of FAK animal models and inhibitors，targeting FAK has been recognized as new treatment for diseases. Most FAK inhibitors show promising preclinical effect without significant adverse effect and several are undergoing clinical trials. This review summarizes the studies on the role of FAK in diseases and related animal models and inhibitors to clarify the underlying mechanism and therapeutic prospect. Related Articles | Metrics
