Cerebral ischemia/reperfusion injury(CIRI)is a pathophysiological process affecting the prognosis of patients with acute ischemic stroke(AIS).Its mechanism is complex and remains unclear.Long non-coding RNA(LncRNA)are a class of non-coding RNA(ncRNA).Early studies of LncRNA focused on their relationship with tumor-related diseases,but recent studies have found that they are also closely related to the pathological process of CIRI.LncRNA participate in the damage and repair processes of CIRI by affecting oxidative stress,autophagy,and apoptosis of the nervous system,as well as the inflammatory response and other mechanisms.They can regulate the progression of CIRI in a positive or negative way,and they play an important role in the related signaling pathways.This review focuses on the mechanisms bv which LncRNA regulate CIRI.

Objective: To explore the mechanism of cistanche deserticola(meat cistanche) in treating Alzheimer′s disease(AD) through network pharmacology, molecular docking, and animal experiments. Methods : Effective components of meat cistanche were mined from the TCMSP database, and AD-related targets were filtered using the SwissTargetPrediction, DisGeNET, and GeneCards databases. The intersection of these targets was analyzed using protein-protein interaction(PPI) networks. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were conducted via the Metascape database. Molecular docking of meat cistanche′s active components with core targets was performed using AutoDock Vina. Based on network pharmacology predictions, an AD model was established using 8-month-old SAMP8 mice, with Morris water maze tests assessing learning and cognitive functions, Nissl staining observing hippocampal neuron morphology, and enzyme-linked immunosorbent assays and Western blotting detecting the expression levels of cAMP signaling pathway-related proteins in hippocampal tissues. Results : Network pharmacology analysis predicted that meat cistanche might act on 74 AD targets through 8 active components. Molecular docking showed high affinity of active components like acteoside with core targets such as ESR1, BDNF, MAPK1, and APP. KEGG analysis indicated involvement in pathways related to cancer, cAMP signaling, and AD. Animal experiments demonstrated that meat cistanche effectively improved learning and cognitive impairments in AD mice and alleviated hippocampal neuron damage. ELISA and Western blotting results indicated that meat cistanche significantly increased the expression levels of cAMP, PKA, P-CREB in the cAMP pathway and promoted the expression of downstream neurotrophic factor BDNF. Conclusion Meat cistanche can improve learning and cognitive disorders in AD model mice and may exert therapeutic effects on AD by up-regulating the cAMP signaling pathway and the expression of downstream BDNF protein targets, thereby improving hippocampal neuron injury.

Objective To investigate the effects of cynomorium songaricum extract on cognitive dysfunction of Alzheimer disease (AD) model mice based on network pharmacology and animal experiments.Methods Network pharmacology was used to predict the related targets and signal pathways of the extract of cynomorium songaricum to improve AD.Senescence accelerated mice P8 (SAMP8) were selected as the model of AD.Based on the results of the preliminary experiment, 0.17 g/(kg·d) was selected as the optimal dosage for the extract of cynomorium son-garicum.The extract of cynomorium songaricum [0.17 g/(kg·d) , Donepezil hydrochloride [2.0 mg/(kg·d) ] and normal saline were given orally for 28 days according to the groups.Morris water maze evaluated the learning and cognitive function of animals.The number of neurons in cornu ammonis 1 (CA1) of hippocampus was observed by Nissl staining.The expression of recombinant Beclin 1(Beclin-1), Sequestosome 1 (p62), light chain 3 (LC-3) protein was detected by immunohistochemical method.The protein expression levels of phosphoinositide 3-ki-nase (PI3K), protein kinase B (AKT) and glycogen synthase kinase3β(GSK-3β) in the hippocampus of mice in each group were detected by Western blot.Results Based on the network pharmacology study, it was predicted that the biological mechanism of cynomorium songaricum to improve AD might be the regulation of autophagy, and the possible signaling pathway was PI3 K/AKT/GSK-3β.The results of animal experiments showed that the extract of cynomorium songaricum could improve the spatial memory learning ability of AD model mice, improve the dam-age of hippocampal neurons, significantly increase the number of neurons, and increase the expression levels of PI3K, p-AKT/AKT, p-GSK-3β/GSK-3β, Beclin-1 and LC3 in the hippocampus of mice.The expression level of p62 decreased.There was no significant difference between male and female mice during the experiment.Conclu-sion The extract may improve the cognitive dysfunction of male and female AD models by activating autophagy mediated by PI3K-AKT-GSK-3β signaling pathway, and there is no significant gender difference in the effect.

By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

Cerebral ischemia-reperfusion injury(CIRI)is a serious complication caused by the recovery of blood flow in the affected brain tissue of patients with ischemic stroke.CIRI patients are often accompanied by neurological dysfunction,cognitive impairment,emotional disorders and other symptoms,which have a serious impact on daily life.At present,CIRI is easy to be diagnosed early,but there are relatively few related specific treatments.In this paper,the correlation between cyclic adenylate-activated exchange protein 1/RAS-related protein 1(Epac1/Rap1)signaling pathway and CIRI is reviewed,in order to provide new ideas for clinical treatment of CIRI patients.

Objective To investigate the effects of acute sleep deprivation on the behavior and synaptic protein expression of rats.Methods Seventy healthy male Wistar rats were randomly divided into seven groups,a Control group and sleep deprivation groups(24,48,72,96,120 and 144 hours).The sleep deprivation rat model was established by the modified multiplatform water environment sleep deprivation method.Spatial learning and memory were assessed by the Morris water maze.Anxiety was assessed by the open field test.The morphology and quantity of hippocampal neurons were observed by Nissl staining.Western blot and Real-time PCR were used to determine the expression of synaptophysin(SYN),post-synaptic density protein-95(PSD-95),and brain-derived neurotrophic factor(BDNF)in rats.Results Compared with the Control group,the numbers of standing and modification were significantly increased by prolongation of the sleep deprivation time(P＜0.05).The escape latency and path length were significantly increased in 120 and 144 h groups(P＜0.05),whereas the number of platform crossings and the percentage of the target quadrant time were significantly decreased(P＜0.01)and negatively correlated to the sleep deprivation time.The expression levels of BDNF,SYN,and PSD-95 were significantly decreased with the prolongation of sleep deprivation time(P＜0.01).Conclusions With the increase in sleep deprivation time,cognitive dysfunction and anxiety gradually deteriorated,which may be related to decreases in the expression of synaptic biomarkers.

Objective To investigate the neuroprotective effect and mechanism of glycosides of Cistanche(GCs)on cerebral ischemia reperfusion injury(CIRI)in rats.Methods Forty-eight male Wistar rats were divided randomly into Sham,Model,GCs,and Nim groups.A rat model of focal CIRI was established by middle cerebral artery occlusion.Neurological function was scored using the Zea-Longa scoring method.The sensory and motor abilities of rats in each group were evaluated by sticker removal,balance beam,and open field tests.The area of cerebral infarction was detected by 2,3,5-triphenyltetrazolium chloride(TTC)staining,Nissl staining was used to observe the morphology of nerve cells,and terminal deoxynucleotidyl transferase dUTP nick end labeling was used to detect apoptosis of nerve cells.Expression levels of the apoptosis-related proteins B-cell lymphoma-2(Bcl-2),Bcl-2 associated X(Bax),and cysteine aspartic protease-3(Caspase-3)were detected by immunohistochemical staining and Western blot.Results Compared with the Sham group,the neurological deficit score was significantly increased(P＜0.05)and the times to remove stickers and passing the balance beam were significantly increased(P＜0.05),motor ability was decreased,infarct size was increased,the number of neurons was decreased,and the number of apoptotic cells was increased after CIRI.Bax and Caspase-3 expression were significantly increased(P＜0.05)and Bcl-2/Bax was significantly decreased(P＜0.05).Compared with the Model group,GCs improved the behavioral performance of CIRI model rats,reduced the infarct size,inhibited cell apoptosis,down-regulated the expression of Bax and Caspase-3(P＜0.05),and up-regulated the expression of Bcl-2/Bax(P＜0.05).Conclusions GCs have a neuroprotective effect on CIRI,and may play a role in inhibiting cell apoptosis by regulating the expression of the apoptosis-related factors Bax,Bcl-2,and Caspase-3.
