Ischemic stroke （IS） is a serious cerebrovascular disease with high clinical incidence. Cerebral ischemia and hypoxia can induce metabolic reprogramming of cellular glycolysis. Hypoxia-inducible factor-1α （HIF-1α） serves as the core transcription factor in the hypoxic response. This article systematically reviews the molecular mechanisms of HIF-1α-mediated glycolytic reprogramming， elaborates on the effects of this metabolic alteration on the functional status of different immune cells， and summarizes the research progress of traditional Chinese medicine （TCM） interventions in this pathological process. HIF-1α reshapes glucose metabolic flux and shifts cellular metabolism toward glycolysis by regulating the transcription of key genes， including glucose transporters， glycolytic rate-limiting enzymes， and mitochondrial oxidative inhibitors. This metabolic disturbance can regulate the activation status， phenotypic differentiation， and functional remodeling of microglia， astrocytes， and peripherally infiltrated immune cells， thereby participating in the mediation of neuroinflammatory responses after IS. Moreover， multiple signaling pathways and the metabolite of glycolysis lactate can exert feedback regulation on this metabolic-immune process. Various active components of TCM and herbal formulas， such as astragaloside Ⅳ， salvianolic acid C， Ginkgo biloba extract， and Mailuo shutong pills， can inhibit abnormal glycolysis， reduce lactate accumulation， and restore the homeostasis of glucose oxidative metabolism by regulating signaling pathways including AMP-activated protein kinase/mammalian target of rapamycin/HIF-1α， HIF-1α/pyruvate kinase M2， and HIF-1α/lactate dehydrogenase A. Consequently， they effectively alleviate neuroimmune inflammation and attenuate ischemic brain injury.

This article summarizes the clinical experience in diagnosing and treating narcolepsy based on the wei qi theory. The key pathogenesis of narcolepsy is considered to be the disharmony of wei qi. In the initial stage， lung， spleen， and kidney deficiency leads to insufficient generation and propulsion of wei qi. In the progressive stage， phlegm-damp and qi stagnation obstruct sanjiao （三焦）， while the interstice of flesh is unrelaxed， and the skin pores are occluded， causing sluggish circulation of wei qi. In the attack stage， pathogens obstruct the upper jiao （焦）， whereas pectoral qi fails to diffuse， and wei qi becomes constrained and blocked in the yin aspect， which may transform into wind or heat and bind with phlegm and stasis， resulting in sudden excessive sleep， cataplexy， dream disturbance， hallucinations， and sleep paralysis. Accordingly， a three-stage differentiation and treatment strategy is proposed， including reinforcing the root and strengthening wei qi in the initial stage with Peiben Shiwei Decoction （培本实卫汤）， resolving phlegm and unblocking the pathways to smooth the flow of wei qi in the progressive stage with Tongjiao Dawei Decoction （通焦达卫汤）， and diffusing wei qi， awakening the spirit， and opening the upper jiao in the attack stage with Xuanwei Xingshen Decoction （宣卫醒神汤）. Clinically， treatment should distinguish deficiency from excess， the primary from the secondary， administer staged and dynamic treatments， and make good use of light， clear， ascending， dispersing， acrid， and aromatic medicinals to restore the movement of wei qi， thereby providing a reference for differentiation and treatment of narcolepsy in traditional Chinese medicine.

Ischemic stroke is a common cerebrovascular disease， characterized by hypoxia and nutritional deficiency in local brain tissue due to insufficient blood supply. Angiogenesis， the formation of new vascular networks on the basis of existing blood vessels， is of great significance for increasing blood flow in the ischemic area of brain tissue， restoring blood and oxygen supply， and improving disease prognosis. This complex process is regulated by various factors， including cytokines， growth factors， and signaling pathways. Among these， the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway is considered a key regulatory pathway. It not only plays an important role in anti-apoptosis and promoting cell survival， but also regulates cell growth， differentiation， migration， and survival， while deeply participating in the regulation of angiogenesis. Chinese medicine offers unique advantages with its multi-component， multi-target， and multi-pathway approach in the treatment of stroke， showing significant potential in treating ischemic stroke. In recent years， it has been found that Chinese medicine can promote angiogenesis after ischemic stroke through the PI3K/Akt signaling pathway. This paper focuses on the PI3K/Akt signaling pathway as the research entry point， and explores in-depth the mechanisms by which Chinese medicine monomers， active components， extracts， derivatives， drug pairs， and Chinese medicine compounds promote angiogenesis after ischemic stroke. The research discusses the regulation of microRNAs （miRNA）， endothelial progenitor cells （EPCs）， apoptosis， upstream pro-angiogenic factors， and downstream target molecules. The paper also elaborates on related research progress， aiming to reveal how Chinese medicine can exert its potential utility in ischemic stroke treatment through this key signaling pathway， providing a theoretical basis for clinical treatment.

ObjectiveTo establish preliminary diagnostic criteria for spleen and kidney deficiency syndrome in ischemic stroke patients and provide a basis for standardized diagnosis and treatment of ischemic stroke. MethodsRelevant literature on the diagnostic criteria for spleen and kidney deficiency syndrome in ischemic stroke patients was retrieved， and data were mined and extracted to form an item pool. Based on the formation of the item pool， this study used the Delphi method to initiate two rounds of questionnaire surveys with selected experts to complete the initial screening of items and the discrimination of symptom importance. A prospective clinical investigation method was adopted to collect clinical information from patients， and statistical analysis methods and data mining techniques were comprehensively used to determine their primary and secondary symptoms. Based on the clear main and secondary symptoms identified， combined with expert group discussions， the study established preliminary diagnostic criteria for spleen and kidney deficiency syndrome in ischemic stroke patients. ResultsA total of 25 relevant syndrome differentiation standards were included. After splitting， standardizing， and screening the items， the study established a pool of 48 items. The first round of questionnaire survey consulted 30 experts， with both the positive coefficient of experts and the effectiveness rate of the questionnaire reaching 100%. The Kendall's coefficient of concordance was 0.359. According to the item screening criteria， 26 items were retained in this round of questionnaire survey. A total of 176 cases were collected through clinical information investigation， including 94 cases with spleen and kidney deficiency syndrome and 82 cases without spleen and kidney deficiency syndrome. The statistical results were as follows： ① Descriptive statistics： The main symptoms with a frequency of ≥ 30% included mental fatigue and lack of strength， weakness of the lower back and knees， etc. The secondary symptoms with a frequency of ≥ 10% and ≤ 30% were lassitude and disinclination to talk， shortness of breath， etc. ② Binary logistic regression analysis： The main symptoms with an odds ratio （OR） value of ≥ 3 were mental fatigue and lack of strength， weakness of the lower back and knees， etc. The secondary symptoms with an OR value of ≥ 1 and ≤ 3 were lassitude and disinclination to talk， shortness of breath， etc. Artificial neural network： The main symptoms with a weight value（W_ij）of ≥ 0.5 and < 1 were mental fatigue and lack of strength， lassitude and disinclination to talk， etc. The secondary symptoms with W_ij of ≥ 0.3 and < 0.5 were shortness of breath， flaccid limbs， etc. In the second round of questionnaire survey， a total of 37 experts were consulted， with both the positive coefficient of experts and the effectiveness rate of the questionnaire reaching 100%. The Kendall's coefficient of concordance was 0.237. According to the criteria to determine primary and secondary symptoms based on the Delphi method， the main symptoms included in this round of the questionnaire were mental fatigue and lack of strength， lassitude and disinclination to talk， etc.， and the secondary symptoms were shortness of breath， dizziness， etc. ConclusionThe main symptoms of spleen and kidney deficiency syndrome in ischemic stroke patients are mental fatigue and lack of strength， weakness of the lower back and knees， loose stool， pale and edematous tongue texture possibly with tooth marks， and deep and thready pulse or weak pulse. The secondary symptoms include shortness of breath， dizziness， tinnitus and deafness， decreased appetite or postprandial abdominal distension， pale complexion， frequent micturition at night， dull tongue texture， and white and slippery tongue coating. The preliminarily established diagnostic criteria for spleen and kidney deficiency syndrome in ischemic stroke patients can provide a standardized and objective basis， thereby better guiding clinical diagnosis and treatment of ischemic stroke.

Cerebral ischemia reperfusion injury(CIRI)is a secondary brain injury that may occur in patients with ischemic stroke during the process of blood flow recovery.NOD-like receptor protein 3(NLRP3)inflammasome plays an important role in the occurrence and development of CIRI.Regulating the activity of NLRP3 inflammasome can induce cell pyroptosis,induce neuroinflammatory response,promote macrophage/microglial polarization,destroy the blood-brain barrier,affect angiogenesis and neurogenesis,thereby affecting CIRI.Traditional Chinese medicine has obvious advantages in the treatment of CIRI.In this paper,with NLRP3 inflammasome as the core,we systematically elucidated the mechanism of action of traditional Chinese medicines on CIRI,and found that traditional Chinese medicines monomers(such as baicalin,polygalasaponin F)and traditional Chinese medicines compound formulas(such as Huangqi guizhi wuwu decoction,Yiqi shengqing formulation)can inhibit NLRP3 inflammasome activity,reduce inflammatory response and oxidative stress,and improve neuronal injury,thereby reducing CIRI.

ObjectiveTo observe the effects of Jianpi Bushen Huoxue prescription （JPBSHX） on rat brain microvascular endothelial cells （RBMECs） based on hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF） signaling pathway， aiming to provide a theoretical basis for the treatment of ischemic stroke. MethodTwelve 8-week-old male SPF-grade SD rats were selected. Eight of them were randomly chosen and given 3.25 g·mL^-1 JPBSHX solution by gavage at a dose of 10 mL·kg^-1 for 5 consecutive days to prepare the medicated serum， which was then preserved for later use. The remaining four rats were given the same volume of normal saline. Follow-up operations were the same as those of the above eight rats. Normal rat serum was collected and stored for later use. RBMECs were revived， cultured， passaged， and randomly divided into five groups： normal group （20% normal rat serum+80% high glucose DMEM）， model group （hypoxia-reoxygenation injury） （20% normal rat serum+80% glucose-free DMEM）， medicated serum group （20% JPBSHX-medicated serum+80% glucose-free DMEM）， medicated serum+HIF-1α inhibitor group （20% JPBSHX-medicated serum+HIF-1α inhibitor 1 mg +80% glucose-free DMEM）， and medicated serum+VEGF inhibitor group （20% JPBSHX-medicated serum +VEGF inhibitor 1 mg+80% glucose-free DMEM）. The relative protein expression levels of Claudin-1 and Claudin-5 in RBMECs， the expression levels of HIF-1α and VEGF in RBMEC culture supernatants， the repair ability of RBMECs， and the number of nodes， microvessels， and their lengths after 72 h of culture were observed in each group. ResultAfter 24 h of reoxygenation， the scratch healing rate in the model group was significantly lower than in the normal group （P<0.01）. Compared with the result in the model group， the scratch healing rates significantly improved in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group （P<0.05）. However， the healing rates in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group were significantly lower than that in the medicated serum group （P<0.05）. The number of nodes， microvessels， and total length of microvessels in the model group were significantly lower than those in the normal group （P<0.01）. These indicators significantly improved in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group compared with those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group compared with those in medicated serum group （P<0.05）. The relative expression levels of Claudin-1 and Claudin-5 proteins were significantly lower in the model group than in the normal group （P<0.01）. These levels were significantly higher in medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group than those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group （P<0.05）. The expression levels of HIF-1α and VEGF in the RBMEC culture supernatants were significantly lower in the model group than those in the normal group （P<0.01）. These levels were significantly higher in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group than those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group （P<0.05）. ConclusionJPBSHX can promote the proliferation， migration， and angiogenesis， such as tubule formation， of RBMECs damaged by hypoxia-reoxygenation injury， and this effect may be achieved through the regulation of the HIF-1α/VEGF signaling pathway.

ObjectiveTo explore the common syndrome elements of cerebral ischemic stroke （CIS） complicated with obstructive sleep apnea-hypopnea syndrome （OSAHS）， reveal the characteristics of traditional Chinese medicine （TCM） syndromes of the disease， clarify the syndrome differentiation and syndrome types， provide evidence for clinical syndrome differentiation， and provide reference for establishing the TCM syndrome type standards of CIS complicated with OSAHS. MethodThe clinical information form of CIS complicated with OSAHS formulated by the research group was used for syndrome survey， and the four-examination information of 300 patients with CIS complicated with OSAHS was collected. The four-examination information of patients was analyzed by latent structure method and comprehensive cluster analysis， and the common syndrome elements of CIS complicated with OSAHS were extracted by combining the TCM basic theory and clinical experience. On this basis， the characteristics of TCM syndromes and the syndrome types in line with reality were summarized. ResultThe top five syndrome elements in patients with CIS and OSAHS are sleep snoring， open mouth breathing， physical obesity， night awakening and dizziness. The top five tongue and pulse manifestations are enlarged tongue， slippery pulse， slippery coating， thick and white coating and purple tongue. The disease locations are the lung， spleen， stomach， kidney， liver and brain. The nature of disease includes deficiency， depression， blood stasis， phlegm， dampness and fire. The clinical syndrome types include the syndrome of stagnation of phlegm and dampness， syndrome of phlegm-dampness blocking the mind， syndrome of spleen deficiency with dampness， syndrome of Yin deficiency leading to fire hyperactivity， syndrome of Qi depression blocking collaterals， syndrome of liver depression and blood stasis， syndrome of Qi deficiency with dampness， and syndrome of Yang deficiency induced water retention. ConclusionIn addition to the common phlegm-， dampness- and blood stasis-related syndromes in patients with CIS and OSAHS， there are also depression- and deficiency-related syndromes. The main etiology and pathogenesis is the disturbance of Qi movement. In clinical practice， attention should be paid to the specific situation of individual patients to differentiate between deficiency and excess， and the treatment should be performed by the method of soothing and reinforcing， or unblocking and clearing， or both.
