Postoperative cognitive dysfunction (POCD) is a clinically significant complication in elderly patients, largely driven by surgery-induced neuroinflammation. The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway, a crucial regulator of innate immunity, has been implicated in neuroinflammatory activation. This study investigated whether electroacupuncture (EA) improves POCD by modulating this pathway in aged rats. Aged male Sprague-Dawley rats were subjected to sevoflurane anesthesia and splenectomy to establish a POCD model. Animals were divided into sham, POCD, POCD+EA, and POCD+EA+cGAS inhibitor groups. The EA groups received stimulation at Baihui (Governor Vessel 20 (GV20)), Neiguan (Pericardium 6 (PC6)), and Zusanli (Stomach 36 (ST36)) acupoints. Cognitive function was evaluated using the Morris water maze, while hippocampal expression of cGAS-STING pathway components and downstream effectors—interferon regulatory factor 3 (IRF3), nuclear factor kappa B (NF-κB), and interleukin-1 beta (IL-1β)—was assessed by Western blot. Cellular localization was determined by immunofluorescence staining. Compared with the Sham group, rats in the POCD group showed significant impairments in spatial memory, accompanied by upregulated protein expression of cGAS, STING, NF-κB, IRF3, and IL-1β in the hippocampus. Upon pathway activation, cGAS and STING proteins were predominantly co-localized with neurons, and their fluorescence intensity in the hippocampus was markedly increased. These behavioral deficits and molecular alterations were partially reversed in both the POCD+EA and POCD+EA+inhibitor groups. Electroacupuncture alleviates POCD in aged rats by inhibiting hippocampal cGAS-STING pathway activation and reducing neuroinflammation, suggesting a promising non-pharmacological strategy for POCD management.

ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy， to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian， and meanwhile， the contents of four index components（geniposide， paeoniflorin， hesperidin and paeonol） were quantitatively analyzed by high performance liquid chromatography（HPLC）. Nonalcoholic fatty liver disease（NAFLD） rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group， model group， lovastatin group（1.8 mg·kg^-1）， combined decoction group（1.26 g·kg^-1） and single decoction group（1.18 g·kg^-1）. After successful modeling， lovastatin group， combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day， and the control group and model group were given equal amounts of normal saline by intragastric administration， after 4 weeks of administration， the serum and liver tissues were collected， and the contents of alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， total cholesterol（TC）， triglyceride（TG）， low-density lipoprotein cholesterol（LDL-C） and high-density lipoprotein cholesterol（HDL-C） in serum of rats were detected， and the liver pathological examination was carried out by hematoxylin-eosin（HE） staining and oil red O staining， so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian， and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide， paeoniflorin， hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples（P<0.01）. The pharmacodynamic results showed that compared with the model group， both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats， reduce the serum levels of AST， ALT， TC， TG and LDL-C， increase the serum level of HDL-C， and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However， there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition， but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

To report a case of an immunocompetent young adult male patient diagnosed with intracranial Aspergillus flavus infection， and to investigate the clinical features of this disease and related experience in diagnosis and treatment.A retrospective analysis was performed for the clinical data of a patient who had the initial presentation of high fever and headache and then progressed to meningoencephalitis， and the results of cerebrospinal fluid （CSF） metagenomic next-generation sequencing （mNGS） and treatment outcomes were summarized.The patient had an acute onset， with no response to empirical anti-infective therapy in the incipient stage， and then he gradually developed disturbance of consciousness and meningeal irritation sign. CSF analysis showed inflammatory changes， while conventional pathogen tests yielded negative results， and mNGS detected 27 specific sequences of Aspergillus flavus. The symptoms of the patient was significantly improved after antifungal therapy with voriconazole， with no recurrence after follow-up for 3 months.For unexplained central nervous system infections， especially those with negative results from conventional tests， mNGS can improve the detection rate of rare pathogens（e.g.，Aspergillus flavus）. Early diagnosis and targeted antifungal therapy are crucial for improving prognosis. This case highlights that invasive fungal infections should be considered even in immunocompetent individuals.

Methods: Epidemic encephalitis B case data in Huzhou City from 2007 to 2023 were collected through the National Notifiable Disease Reporting System of the Chinese Disease Prevention and Control Information System. The temporal, regional and population distribution characteristics of laboratory-confirmed epidemic encephalitis B cases were analyzed using the descriptively epidemiological method. Results: A total of 49 laboratory-confirmed epidemic encephalitis B cases were reported in Huzhou City from 2007 to 2023, and the average annual incidence was 0.10/105, showing a significant downward trend (P<0.05). The epidemic encephalitis B cases were concentrated from July to August, and July was the peak month, with 40 cases accounting for 81.63%. There was a statistically significant difference in the average annual incidences of epidemic encephalitis B among counties (districts) (P<0.05). Nanxun District had the highest reported incidence, with an average annual incidence of 0.23/105. There were 30 male cases and 19 female cases, with a male-to-female ratio of 1.58∶1. The youngest case was 5 months old, and the oldest was 49 years old. The children under 15 years were in the majority, with 42 cases accounting for 85.71%. Most of the cases were scattered children, with 25 cases accounting for 51.02%. There were 22 cases with no vaccination history and 21 cases with an unknown vaccination history, accounting for 44.90% and 42.86% respectively. All cases presented with fever. Other main clinical symptoms included listlessness, drowsiness, vomiting and headache, with 47, 40, 33 and 29 cases respectively, accounting for 95.92%, 81.63%, 67.35% and 59.18%, respectively. Conclusions The incidence of epidemic encephalitis B in Huzhou City remained at a relatively low level from 2007 to 2023, with Nanxun District being the high-risk area and July being the peak month for disease incidence. Fever and listlessness were the predominant clinical manifestations. Strengthening vaccination for children under 15 years should be prioritized.

BACKGROUND: Gluconeogenesis is a critical metabolic pathway for maintaining glucose homeostasis, and its dysregulation can lead to glycometabolic disorders. This study aimed to identify hub biomarkers of these disorders to provide a theoretical foundation for enhancing diagnosis and treatment. METHODS: Gene expression profiles from liver tissues of three well-characterized gluconeogenesis mouse models were analyzed to identify commonly differentially expressed genes (DEGs). Weighted gene co-expression network analysis (WGCNA), machine learning techniques, and diagnostic tests on transcriptome data from publicly available datasets of type 2 diabetes mellitus (T2DM) patients were employed to assess the clinical relevance of these DEGs. Subsequently, we identified hub biomarkers associated with gluconeogenesis-related glycometabolic disorders, investigated potential correlations with immune cell types, and validated expression using quantitative polymerase chain reaction in the mouse models. RESULTS: Only a few common DEGs were observed in gluconeogenesis-related glycometabolic disorders across different contributing factors. However, these DEGs were consistently associated with cytokine regulation and oxidative stress (OS). Enrichment analysis highlighted significant alterations in terms related to cytokines and OS. Importantly, osteomodulin ( OMD ), apolipoprotein A4 ( APOA4 ), and insulin like growth factor binding protein 6 ( IGFBP6 ) were identified with potential clinical significance in T2DM patients. These genes demonstrated robust diagnostic performance in T2DM cohorts and were positively correlated with resting dendritic cells. CONCLUSIONS Gluconeogenesis-related glycometabolic disorders exhibit considerable heterogeneity, yet changes in cytokine regulation and OS are universally present. OMD , APOA4 , and IGFBP6  may serve as hub biomarkers for gluconeogenesis-related glycometabolic disorders.
