ObjectiveTo investigate the mechanism of action of Bushen Huoxue prescription （BSHXP） in regulating premature ovarian failure in rats through the PTEN-induced kinase 1 （PINK1）/Parkinson's protein （Parkin） signaling pathway-mediated mitophagy. MethodsA total of 48 rats were randomly divided into a blank group consisting of eight rats， while the remaining 40 rats underwent modeling. The modeling group was intraperitoneally injected with 4 mg·kg^-1 cisplatin solution， followed by a second injection one week later， for a total of two injections. The estrous cycle was observed through vaginal smears for 14 consecutive days to determine whether the modeling was successful. The successfully modeled rats were randomly divided into a model group， groups receiving low， medium， and high doses of BSHXP at 9.72， 19.44， and 38.88 g·kg^-1·d^-1 （BSHXP-L， BSHXP-M， and BSHXP-H groups）， and a positive control group treated with estradiol valerate （0.09 mg·kg^-1·d^-1）， for 21 consecutive days. The body weight of the rats was measured weekly. After the final administration， rats were anesthetized， and their blood and ovaries were collected. The ovarian weight was measured. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of anti-Müllerian hormone （AMH）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂）. Assay kits were used to measure the levels of superoxide dismutase （SOD） and malondialdehyde （MDA） in the rat serum. Hematoxylin-eosin （HE） staining was used to observe the morphological changes in the ovaries. Immunohistochemistry （IHC） was performed to detect microtubule autophagy-related protein 1 light chain 3B（LC3B） protein expression in ovarian tissue， and electron microscopy was employed to examine the mitochondrial and autophagosome changes in the rat ovaries. Western blot was used to detect the protein expression of PINK1， Parkin， LC3B， and p62. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of PINK1， Parkin， LC3B， and p62 in ovarian tissue. ResultsCompared with the blank group， the model group showed significant reductions in body weight， weight gain， and ovarian weight （P<0.01）， along with decreased serum AMH and E₂ levels （P<0.01）， while FSH and LH levels were increased （P<0.01）. Serum MDA levels were significantly increased （P<0.01）， and SOD levels were significantly reduced （P<0.01）. The ovarian tissue structure was disordered， and the zona pellucida was wrinkled into an irregular acidophilic annular object， accompanied by an increased number of closed follicles. Electron microscopy showed mitochondrial swelling， unclear structure， and no obvious autophagosomes and autolysosome structures. The proteins and mRNA expression levels of PINK1， Parkin， LC3B， and p62 in the ovarian tissue were significantly reduced （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of increases in body weight and ovarian weight （P<0.05， P<0.01）. Except for the BSHXP-L group， all treatment groups showed increased body weight gain （P<0.01）. All treatment groups showed significantly increased serum AMH and decreased FSH levels （P<0.01）. Except for the BSHXP group， all treatment groups showed varying degrees of increase and decrease in serum E₂ and LH levels （P<0.05， P<0.01）. All treatment groups showed reduced serum MDA levels （P<0.01）， while the BSHXP-M， BSHXP-H， and the positive control groups demonstrated improved serum SOD levels （P<0.05， P<0.01）. All treatment groups showed an increased number of follicles at all stages， visible mature follicles， and a decreased number of closed follicles. Electron microscopy showed relieved mitochondrial swelling， morphology close to normal， clear structure， and visible formation of autolysosomes in all treatment groups. Additionally， the protein and mRNA expression levels of PINK1， Parkin， LC3B， and p62 in ovarian tissue were significantly increased （P<0.05， P<0.01）. ConclusionBSHXP may improve ovarian function in rats with premature ovarian failure by regulating the PINK1/Parkin signaling pathway， activating mitochondrial autophagy， and reducing oxidative damage.

ObjectiveBased on transcriptomics， to explore the mechanism of Hei Xiaoyaosan regulating the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to improve the learning and memory ability of insomnia rats with liver depression syndrome. MethodsSixty 8-week-old male SD rats were randomly divided into the blank group， model group， eszopiclone group （0.09 mg·kg^-1）， and low， medium， and high dose groups of Hei Xiaoyaosan （3.82， 7.65， 15.30 g·kg^-1）， with ten rats in each group. Except for the blank group， the other groups were induced insomnia rat model with liver depression by chronic restraint， tail clamping stimulation and intraperitoneal injection of p-chlorophenylalanine （PCPA）. Each treatment group received intragastric administration according to the specified dosage， once a day for 14 consecutive days. The pentobarbital sodium cooperative sleep test， open field test， and Morris water maze test were used to test the sleep quality， depressive-like behavior， and learning and memory abilities of rats. Additionally， enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of 5-hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， brain-derived neurotrophic factor （BDNF）， glial cell line-derived neurotrophic factor （GDNF） and nitric oxide （NO） in hippocampus. Hematoxylin-eosin （HE） staining was performed to observe pathological changes of the hippocampal tissue， while terminal deoxynucleotidyl transferase deoxyuridine triphosphate （dUTP） nick end labeling （TUNEL） was used to evaluate apoptosis of hippocampal neurons. Transcriptomic sequencing technology was employed to identify differentially expressed genes in hippocampus between the model group and the blank group， as well as between the medium-dose group of Hei Xiaoyaosan and the model group. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis were performed on the intersecting genes. Subsequently， the enriched key genes and signaling pathways were analyzed and verified. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to assess the mRNA expression levels of phosphatase and tensin homolog （PTEN）， B-cell lymphoma-2 （Bcl-2）-like protein 11 （BCL2L11）， and mitogen-activated protein kinase 1 （MAPK1） in hippocampus， and Western blot was employed to evaluate the protein expressions of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， Bcl-2， Bcl-2-associated X protein （Bax）， and cleaved Caspase-3 in the same tissue. ResultsCompared with the blank group， the model group exhibited a reduction in body weight， an increase in sleep latency， and a decrease in sleep duration （P<0.01）. Additionally， rats showed obvious depression-like behavior， and their learning and memory abilities decreased. Furthermore， the contents of 5-HT， GABA， NO， BDNF and GDNF in hippocampus decreased （P<0.01）. Histological examination revealed a disorganized cell arrangement in the CA1 region of the hippocampus， characterized by irregular cell shapes， a reduced cell count， deeply stained and pyknotic nuclei， increased vacuolar degeneration， and an elevated apoptosis rate （P<0.01）. Compared with the model group， the body weight of the high and medium dose groups of Hei Xiaoyaosan increased， the sleep latency shortened and the sleep time prolonged （P<0.05， P<0.01）. Additionally， depression-like behavior and learning and memory abilities of rats were significantly improved， the levels of 5-HT， GABA， NO， BDNF and GDNF in the hippocampus increased （P<0.05， P<0.01）. These interventions also ameliorated pathological damage in the hippocampal CA1 area and reduced the apoptosis of hippocampal neurons （P<0.01）. Transcriptomic sequencing results indicated that Hei Xiaoyaosan might exert a therapeutic effect by regulating PI3K/Akt pathway through key mRNAs such as PTEN， BCL2L11， and MAPK1. The roles of these key mRNAs and proteins within PI3K/Akt pathway were further validated. In comparison to the blank group， the expression levels of PTEN， BCL2L11 and MAPK1 mRNA in the hippocampus of rats in the model group were increased （P<0.01）， while the protein expression levels of p-PI3K， p-Akt and Bcl-2 were decreased （P<0.01）， and the protein expression levels of PTEN， Bax and cleaved Caspase-3 were increased （P<0.01）. Compared with the model group， the high-dose and medium-dose groups of Hei Xiaoyaosan could down-regulate the expressions of PTEN， BCL2L11 and MAPK1 mRNAs （P<0.01）， up-regulate the expressions of p-PI3K， p-Akt and Bcl-2 proteins （P<0.01）， and down-regulate the protein expressions of PTEN， Bax and cleaved Caspase-3 （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan may regulate PI3K/Akt signaling pathway by down-regulating expressions of key genes such as PTEN， BCL2L11 and MAPK1， and thus improve the learning and memory abilities of insomnia rats with liver depression syndrome.

ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， network pharmacology and pharmacodynamics， to investigate the pharmacodynamic material basis and mechanism of Hei Xiaoyaosan in improving learning and memory ability of insomnia rats. MethodUPLC-Q-TOF-MS was used to characterize the chemical constituents of Hei Xiaoyaosan. Network pharmacology was applied to construct the network of active ingredients-intersecting targets-pathways， and molecular docking was performed on key ingredients and core targets. Sixty 8-week-old male SD rats were selected and randomly divided into blank group， model group， Hei Xiaoyaosan low， medium， and high dose groups（3.82， 7.65， 15.30 g·kg^-1）， and zolpidem tartrate group（0.5 mg·kg^-1）， with 10 rats in each group. Except for the blank group， the insomnia model was induced by intraperitoneal injection of p-chlorophenylalanine（PCPA） for 4 consecutive days. Rats in each dosing group were administered the corresponding dose by gavage， once a day for 14 consecutive days. Morris water maze test was utilized to assess the learning and memory ability of rats， transmission electron microscopy was employed to examine the ultrastructure of hippocampal synapses， enzyme-linked immunosorbent assay（ELISA） was conducted to analyze the levels of 5-hydroxytryptamine（5-HT）， interleukin-6（IL-6）， and tumor necrosis factor-α（TNF-α） in hippocampal tissues， and Western blot was performed to detect the expression levels of tumor suppressor protein p53（TP53）， rat sarcoma virus（RAS）， epidermal growth factor receptor（EGFR）， cyclic adenosine monophosphate（cAMP）-response element binding protein（CREB） binding protein（CREBBP）， glycogen synthase kinase-3β（GSK-3β）， protein kinase B1（Akt1）， nitric oxide synthase 1（NOS1）， phosphorylated（p）-Akt1， and p-GSK-3β in hippocampal tissues. Additionally， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to assess the mRNA expression levels of TP53， RAS， EGFR， CREBBP， GSK-3β， Akt1 and NOS1. ResultA total of 176 components were identified in Hei Xiaoyaosan， mainly flavonoids， triterpene saponins， phenylpropanoids and other compounds. Network pharmacological analysis revealed that TP53， V-Ha-Ras Harvey Rat sarcoma viral oncogene homolog（HRAS）， neuroblastoma sarcoma viral oncogene homolog（NRAS）， EGFR， CREBBP， GSK-3β， Akt1 and NOS1 were the key targets of Hei Xiaoyaosan in treating insomnia. The core targets were predominantly associated with cAMP， RAS， Ras-associated protein 1（Rap1）， advanced glycation end products（AGE）/receptor for AGE（RAGE）， and EGFR signaling pathways， and the key active ingredients of Hei Xiaoyaosan in treating insomnia were 8-shogaol， ligustilide F， 6-gingerol， levistilide A and senkyunolide E. Animal experiment results demonstrated that Hei Xiaoyaosan medium and high dose groups significantly increased body weight， shortened sleep latency and prolonged sleep duration in insomnia rats（P<0.01）， significantly decreased escape latency and increased platform crossing frequency（P<0.01）， and improved the pathological changes of hippocampal synaptic ultrastructure. Meanwhile， the two groups could significantly elevate 5-HT level， Akt1 mRNA expression， Akt1 and p-Akt1 protein expression（P<0.01）， reduce inflammatory factor levels（P<0.01）， and down-regulate protein expression levels of TP53， RAS， NOS1， EGFR， CREBBP， GSK-3β and p-GSK-3β（P<0.01）， as well as mRNA expression levels of TP53， RAS， NOS1， EGFR， CREBBP and GSK-3β in hippocampal tissues（P<0.01）. ConclusionThis study determined that the five key active ingredients（8-shogaol， ligustilide F， 6-gingerol， levistilide A and senkyunolide E） in Hei Xiaoyaosan may improve the learning and memory ability of insomnia rats by regulating signaling pathways such as cAMP， RAS， and EGFR， providing an important reference for its mechanism research and clinical application.

Objective To explore the microbiological characteristics of Staphylococcus aureus(S.aureus)with no-vel incomplete hemolytic phenotype(SIHP).Methods Hemolytic phenotypes were detected and categorized by u-sing the three-point inoculation method.A total of 11 novel SIHP and 33 randomly matched S.aureus with com-plete hemolytic phenotype(SCHP)were included.Antibiotic susceptibility test was performed using broth microdi-lution method.Coagulase test was performed with freeze-dried rabbit plasma.Catalase activity was detected by slide catalase test.Expression of hemolysin genes was detected by qRT-PCR.Toxicity to human red blood cells was as-sessed by microplate method.Microplate biofilm formation was measured using crystal violet staining method.Growth kinetic determination was performed through microcultivation assay.Results Compared with SCHP,the expression profiles of the four hemolysin genes(hla,hlb,hlc,and hld)in the new SIHP were different.The new SIHP had higher resistance rates to penicillin,oxacillin,gentamicin,quinolones,clindamycin,and trimethoprim-sulfamethoxazole.Furthermore,the new SIHP had stronger hemolytic toxicity,plasma coagulase activity,and bio-film formation ability.Additionally,the new SIHP grown faster in the logarithmic phase.Conclusion Taken to-gether,the microbiological characteristics of the new SIHP are different from those of SCHP,including stronger an-tibiotic resistance and pathogenicity,which should be paid more attention by clinicians.

Objective:To explore the association of cerebral venous outflow assessed by CT angiography (CTA) with first pass effect (FPE) in patients with acute anterior circulation large vessel occlusion accepted mechanical thrombectomy (MT).Methods:A retrospective analysis was performed; patients with acute anterior circulation large vessel occlusion accepted MT and CTA in Department of Neurology, Affiliated Hospital of Xuzhou Medical University from July 2018 to June 2021 were consecutively enrolled. Cerebral venous outflow in baseline CTA was evaluated using Cortical Vein Opacification Score (COVES). Patients were categorized into either FPE or non-FPE groups based on recanalization of occluded vessels after initial MT. General information, clinical features, radiological data, and surgery-related data between the 2 groups of patients were collected and compared. Significant variables ( P<0.1) from univariate analysis were included into a multivariable Logistic regression model to explore the relation between COVES and FPE. Predictive value of COVES in FPE was assessed using receiver operating characteristic (ROC) curve. Results:Out of the 143 patients enrolled in this study, 52 were into the FPE group and 91 were into the non-FPE group. Compared with the non-FPE group, the FPE group had higher COVES scores, higher proportion of patients with good cerebral venous drainage (COVES≥3), smaller core infarct volume, and shorter time from femoral artery puncture to vessel recanalization, with significant differences ( P<0.05). Multivariable Logistic regression analysis revealed that COVES was still corelated with FPE after adjusting covariates such as baseline NIHSS scores, core infarct volume, and time from femoral artery puncture to vessel recanalization ( OR=0.730, 95% CI: 0.567-0.940, P=0.015). ROC curve demonstrated that the combined model of COVES with aforementioned factors (COVES scores+baseline NIHSS scores+core infarct volume+time from femoral artery puncture to vessel recanalization) had an area under the curve of 0.757 (95% CI: 0.672-0.841, P<0.001), with sensitivity of 61.5% and specificity of 78.0%. Conclusion:Favorable cerebral venous drainage is an independent predictor for successful FPE in patients with acute anterior circulation large vessel occlusion accepted MT.
