OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets， followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established ， and the zebrafish were treated with L. ruthenicum Murr. extract （LRME） at concentrations of 0.1， 0.2 and 0.4 mg/mL， respectively； 24 h later， behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 （IL-6）， IL-1β， IL-10， tumor necrosis factor-α （TNF-α）]， oxidative stress markers [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， catalase （CAT）]， and neurotransmitters [5- hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， glutamic acid （Glu）， dopamine （DA）， and norepinephrine （NE）] were measured. The protein expression levels of protein kinase B1 （AKT1）， phosphorylated AKT1 （p-AKT1）， epidermal growth factor receptor （EGFR）， B-cell lymphoma 2 （Bcl-2）， sarcoma proto-oncogene，non-receptor tyrosine kinase （SRC）， and heat shock protein 90α family class A member 1 （HSP90AA1） in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these， apigenin， naringenin and others were recognized as core active compounds， while AKT1， EGFR and others served as key targets； EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-， medium-， and high-dose groups were 54.60%， 69.03% and 77.97%， 开发。E-mail：hjp_yft@163.com respectively， while the inhibition ratios of locomotor distance were 0.57， 0.83 and 0.95， respectively. Compared with the model group， the number of resting counts， resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups （P＜0.05）. Neuronal damage in the brain was alleviated. Additionally， the levels of IL-6， IL-1β， TNF-α， MDA， Glu， DA and NE， as well as the protein expression levels of AKT1， p-AKT1， EGFR， SRC and HSP90AA1， were markedly reduced （P＜0.05）， while the levels of IL-10， SOD， GSH-Px， CAT， 5-HT and GABA， as well as Bcl-2 protein expression， were significantly elevated （P＜0.05）. CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects， and its specific mechanism may be related to the regulation of inflammatory responses， oxidative stress， neurotransmitter balance， and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

γδ T cells possess both innate and adaptive immune characteristics. Their antigen recognition is independent of major histocompatibility complex presentation， and they can directly recognize abnormal tumor metabolism， showing unique application potential in tumors with low immune infiltration. This paper systematically sorts out the biological characteristics and antitumor immune functions of γδ T cells， and mainly reviews the relevant mechanisms by which active ingredients of traditional Chinese medicine regulate γδ T cells to exert antitumor immune functions. Glycyrrhiza polysaccharide and Astragalus polysaccharide can enhance the antitumor immune function of γδ T cells by promoting the expression of various cytokines， regulating intestinal flora and alleviating immunosuppressive state. Quercetin and puerarin can strengthen γδ T cell-mediated tumor cell killing by regulating the proliferation of γδ T cells， the expression of cytotoxic effector molecules and related signaling pathways. Toosendanin can potentiate γδ T cell-induced tumor cell killing by down-regulating the expression of anti-apoptotic protein in tumor cells. Artesunate can boost γδ T cell-mediated antitumor immune responses by enhancing the effector function of γδ T cells and weakening tumor immune escape. Future research shall focus on exploring the synergistic effects and molecular mechanisms of the combined application of active ingredients of traditional Chinese medicine and γδ T cell immunotherapy， and identifying the key targets for γδ T cells to exert antitumor immune functions.

ObjectiveTo explore the effects of different dosage forms of Kaixinsan （KXS） on the morphology and function of mitochondria in rat models of Alzheimer's disease （AD） and potential mechanisms of action. MethodsMale SD rats were randomly assigned to a sham group， model group， treatment groups receiving KXS decoction， powders， and granules （3.08 g·kg^-1）， as well as donepezil group （0.51×10^-3 g·kg^-1）， with 10 rats in each group. AD model was created using intracerebroventricular injection of streptozocin （STZ）. After 30 days of administration， behavioral assessments were conducted， and mitochondrial morphology was observed using transmission electron microscopy. Mitochondrial respiratory chain complex content was measured via enzyme-linked immunosorbent assay （ELISA）. Changes in mitochondrial membrane potential were measured via JC-1 staining， and superoxide dismutase （SOD） activity and reactive oxygen species （ROS） levels were measured via biochemical assays. The mRNA expression of adenosine 5'-monophosphate-activated protein kinase （AMPK）， peroxisome proliferator-activated receptor gamma coactivator-1α （PGC-1α）， and silent information regulator 3 （SIRT3） was detected by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）， and Western blot was used to examine the protein expression levels of optic atrophy protein1 （OPA1）， mitochondrial fission protein 1 （FIS1）， AMPK， p-AMPK， PGC-1α， and SIRT3. ResultsCompared with the sham group， rats in the model group had significantly lower recognition index， spontaneous alternation rate， escape latency， number of platform crossings， time spent in the target quadrant， and percentage of distance traveled in the target quadrant distance （P<0.05， P<0.01）. Significant mitochondrial damage was observed in the hippocampal tissue， with a marked decrease in mitochondrial respiratory chain complex content （P<0.01） and reduced mitochondrial membrane potential （P<0.05）. Additionally， the SOD activity was reduced， while ROS levels were elevated （P<0.01）. The mRNA expression of PGC-1α and SIRT3 was significantly downregulated （P<0.01）， along with decreased protein expression levels of OPA1， p-AMPK/AMPK， PGC-1α， and SIRT3， whereas FIS1 protein expression was significantly upregulated （P<0.05， P<0.01）. Compared with the model group， rats in KXS-treated groups （various dosage forms） showed significant improvement in behavioral indexes （P<0.05， P<0.01）， reduced hippocampal mitochondrial damage， and more organized mitochondrial cristae. Mitochondrial respiratory chain complex content was significantly increased （P<0.05， P<0.01）， and mitochondrial membrane potentials were elevated （P<0.05）. SOD activity was elevated， and ROS levels were significantly reduced （P<0.05， P<0.01）. Furthermore， the mRNA expression of PGC-1α and SIRT3 was upregulated， with increased protein levels of OPA1， p-AMPK/AMPK， PGC-1α， and SIRT3， while FIS1 protein expression levels were significantly reduced （P<0.05， P<0.01）. Across the KXS-treated groups， the granule group showed a higher spontaneous alternation rate than the decoction and powder groups （P<0.05）. ConclusionKXS decoction， powders， and granules can improve the learning and memory ability of rats， with granules being the most effective. The mechanism of action may involve activation of the AMPK/PGC-1α/SIRT3 signaling pathway， improvement of the mitochondrial function， and subsequent amelioration of the brain energy metabolism disorders.

Objective To investigate the effect of Danshen Baoxin Cha (DBC) on a rat model of coronary heart disease combined with cognitive impairment. Methods Male Sprague-Dawley(SD) rats were randomly assigned to two groups:normal group and model group. Streptozotocin was injected into the bilateral ventricles of rats in the model group to establish cognitive impairment model,then isoproterenol hydrochloride was injected subcutaneously to model myocardial ischemia. Behavioral experiments were conducted to verify the success of the model of cognitive dysfunction. The rats of the model group were randomly divided into five groups:model control group,Tongxinluo Capsule group (TXL group,1.6 g·kg-1),and low-(4 g·kg-1),medium-(8 g·kg-1),and high-(16 g·kg-1) dose DBC groups. These groups were received the respective treatments continuously for two weeks. Subsequently,the Y-maze,novel object recognition and Morris water maze experiment were employed to assess the learning and memory abilities of rats. A kit was utilized to quantify the level of oxidative stress in the brain and the adenosine triphosphate (ATP) content in the brain and mitochondria. Hematoxylin-eosin (HE) staining and Nissl staining were employed to observe the pathological changes of neurons in hippocampus CA1 region. Electron microscopy was utilized to observe the pathological changes of mitochondria in hippocampal CA1 region. The expression levels of peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α),glucose transporter type 4(GLUT4),and optic atrophy 1(OPA1) were quantified by real-time fluorescence quantitative polymerase chain reaction (PCR),and the expression of proteins related to the AMPK/OPA1 signaling pathway was determined by Western Blot analysis. Results Compared with the normal group,the spontaneous alternating reaction rate,the novel object recognition index,number of crossing the original platform,and distance ratio in the model group were obviously decreased (P<0.01). Neuronal density in the CA1 region of the hippocampus was decreased,Nissl bodies were decreased,and nucleus consolidation was increased. The ATP level in mitochondria,and the levels of ATP,SOD,and GSH-PX in brain were significantly decreased(P<0.05,P<0.01),as well as the content of ROS and MDA were significantly increased (P<0.05,P<0.01). The mitochondria of hippocampus in CA1 region were swollen,with sparse and vacuolated cristae. The mRNA expression levels of GLUT4,PGC-1α,and OPA1 were significantly decreased (P<0.01). The protein expression levels of GLUT4,SIRT1,PGC-1α and OPA1,and p-AMPK/AMPK ratio were significantly decreased (P<0.05,P<0.01). Compared with the model group,the behavioral indexes of rats in the DBC groups were significantly improved (P<0.05,P<0.01),the number of neurons in the hippocampal CA1 area,Nissl bodies and nucleus consolidation were improved. The ATP level in mitochondria and the levels of ATP,SOD,and GSH-PX in brain were significantly increased (P<0.05,P<0.01). The levels of ROS and MDA were significantly decreased (P<0.05,P<0.01). The structure of mitochondrial cristae in hippocampal CA1 region were relatively intact. The mRNA expression levels of GLUT4,PGC-1α and OPA1 were increased (P<0.05,P<0.01),and the expression of proteins related to the AMPK/OPA1 signaling pathway was significantly increased(P<0.05,P<0.01). Conclusion DBC can enhance learning and memory abilities,reduce neuronal damage in a rat model of coronary heart disease combined with cognitive impairment. The mechanism may be related to the reduction of oxidative stress damage in the brain,the activation of the AMPK/OPA1 signaling pathway,and the restoration of energy levels.

Objective To explore the mechanism of action of Danshen Baoxin Cha(DBC) on depressed mice with coronary heart disease (CHD) based on network pharmacology and NLRP3 inflammatory pathway. Methods (1) TCMSP and BATMAN-TICAM databases were used to screen the DBC active ingredients and targets. The targets of CHD with depression were screened using the OMIM and Genecards databases. The targets of DBC active ingredients and related targets of CHD with depression were imported into Venny 2.1 online platform to obtain the intersection targets,which was the potential target of DBC in the treatment of CHD with depression. Protein-protein interaction (PPI) analysis was performed on the intersection targets using the STRING platform to screen the key targets. A "drug-active ingredients-disease-targets" network was created to select the main active ingredients and core targets of DBC for the treatment of CHD with depression. Thereafter,the primary targets were examined by GO function and KEGG pathway enrichment using the Metascape database.(2)Kunming mice were split into six groups of eight mice each at random:the control group,the model group,the positive control group (metoprolol tartrate 5.14 mg·kg-1+sertraline hydrochloride 10.3 mg·kg-1),and the DBC high-,middle-,and low-dose groups (30.8,15.4 and 7.7 g·kg-1·d-1). Chronic unpredictable mild stimulation (CUMS)and subcutaneous injection of isoprenaline hydrochloride (ISO) were used to induce a mice model of CHD with depression. Mice were treated orally with the corresponding drug once a day for 18 consecutive days. Behavioral experiments involving forced swimming test,tail suspension test,and open-field test were applied to detect depression levels of mice. Histopathological alterations in hippocampus tissues were noted using HE and Nissl staining. qPCR was used to determine the mRNA expression levels of IL-6,TNF-α,NLRP3,IL-1β,IL-10,and Caspase-1 in hippocampus tissues. Results(1) Sixty-five active components in Salvia and seven active components in green tea were screened out. A total of 1042 potential targets and 2116 CHD complicated with depression-related targets were obtained. The intersection of the targets of active components and disease-related targets was performed by Venny 2.1.0 platform to obtain 299 potential targets (common targets) of DBC in the treatment of CHD with depression. The core targets including IL-1β,AKT1,TNF-α,IL-6,VEGFA,CASP3 and IL-10 were screened through PPI network analysis of potential targets. Key active ingredients including vitamin B,luteolin,salvianolic acid,tanshinone ⅡA and catechin,as well as key targets,such as PTGS2、IL-1β、IL-6、TNF-α and IL-10,were obtained by network analysis of "drugs-active ingredients-disease-targets". The potential targets were correlated with biological processes such as inflammation response,regulation of tumour necrosis factor (TNF),glucocorticoid regulation,regulation of nuclear factor kappa B(NF-κB) transcription factor,as well as major pathways including PI3K-Akt signaling pathway,TNF signaling pathway,apoptosis signaling pathway,and NF-κB signaling pathway.(2) Compared with the control group,mice in the model group showed a significant decrease in the total and center distance of the open field (P<0.01) and a significant increase in the time of forced swimming and immobility time of tail suspension test (P<0.01). The mRNA expression of IL-6,TNF-α,NLRP3,IL-1β,and Caspase-1 was significantly up-regulated(P<0.01) in the hippocampus tissues,but IL-10 mRNA expression was down-regulated (P<0.05). Compared with the model group,the total and center distance in DBC high-,middle-,and low-dose groups were significantly up-regulated(P<0.05,P<0.01),and the time of forced swimming and immobility time of tail suspension test were significantly down-regulated (P<0.01). The mRNA expression of IL-6,TNF-α,NLRP3,IL-1β and Caspase-1 of the DBC high-,middle-,and low-dose groups were significantly down-regulated(P<0.01),IL-10 mRNA expression in mice hippocampus tissue of DBC high-and middle-dose groups was up-regulated (P<0.01). Conclusion The intervention effect of DBC on depressed mice with CHD may be achieved by active ingredients including luteolin,tanshinone,salvianolic acid and catechin acting on the key targets,such as IL-6,TNF-α,IL-1β and IL-10,to regulate the NLRP3 inflammatory signaling pathway.

Background Tributyl phosphate (TBP) is widely used as an organophosphate flame retardant. However, there are limited studies on the toxicity of TBP to aquatic organisms at low levels of exposure. Objective To investigate the effects of TBP on early development of zebrafish (Danio rerio). Methods Zebrafish embryos were randomly divided into four groups at 2 h post-fertilisation (2 hpf), namely, the 0.01% dimethyl sulfoxide (DMSO) control group and TBP exposure groups (0.02, 0.2 and 2 μg·L⁻¹). The exposure time was from 2 hpf to 120 hpf and the hatching rate, malformation rate, heart rate and body length of zebrafish embryos at 72 hpf, the frequency of tail curling at 24-29 hpf, the locomotor ability at 96 hpf and the survival rate at 120 hpf were evaluated, respectively. The whole-body triiodothyronine (T₃) and tetraiodothyronine (T₄) levels of juvenile fish were measured by enzyme immunoassay at the end of the infection, and the expression levels of hypothalamic-pituitary-thyroid axis (HPT) and neurodevelopmental-related genes were detected by quantitative real-time PCR (q-PCR). Results The heart rates of zebrafish embryos were significantly decreased in all TBP-treated groups (P<0.001), the survival rates of the 0.02 and 2 μg·L⁻¹ TBP groups were significantly decreased (P<0.05), and the malformation rate of the 2 μg·L⁻¹ treated group was significantly increased (P<0.05), which was mainly manifested by pericardial oedema. The frequency of tail curling of zebrafish embryos in all groups reached the highest at 25 hpf, which was significantly lower (P<0.001) in all exposure groups than in the control group (P<0.001). In the locomotor behaviour experiments, the swimming speed of zebrafish larvae in the dark cycle was significantly decreased in the 0.02 and 0.2 μg·L⁻¹ TBP groups (P<0.05), and similar results were found for the light cycle in the 0.2 and 2 μg·L⁻¹ TBP groups (P<0.05). Compared with the control group, the T₃ level of zebrafish juveniles in the 0.2 μg·L⁻¹ TBP group increased significantly (P<0.05). The q-PCR results showed that the expression levels of HTP axis-related genes [thyroid hormone receptors (trα, \begin{document}$tr\beta $\end{document}), thyroglobulin (tg), and sodium/iodide co-transporter (nis)] were significantly down-regulated in the exposure groups, the expression level of transthyretin (ttr) was significantly up-regulated in the 0.02 μg·L⁻¹ TBP group, and the iodothyronine deiodinase 2 (dio2) expression level was significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05); the neurodevelopment-related gene acetylcholinesterase (ache) was significantly down-regulated in the exposure groups, and the expression levels of myelin basic protein (mbp) and Elav like neuron-specific RNA binding protein 3 (elavl3) were significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05). Conclusion TBP exposure can lead to early developmental abnormalities in zebrafish, manifested as developmental toxicity, thyroid endocrine disruption and neurotoxicity during hatching and early juvenile stages.
