Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

LIU Wansu, as the foremost of the four great masters of the Jin-Yuan period, established the "theory of fire-heat'' and extended the fire-heat pathogenesis framework to the field of stroke, thereby forming the theory of ''fire-heat inducing stroke''. This achieved a paradigmatic shift in stroke etiology from ''exogenous wind inducing stroke'' to ''fire-heat inducing stroke''. This paper systematically reviews the developmental trajectory of LIU Wansu's ''fire-heat inducing stroke'' theory and explores the social background, academic origins, and core connotations of its theoretical construction. The study found that, based on the ''Nineteen Pathomechanisms'' in the Huangdi's Internal Classic (Huang Di Nei Jing) and combined with clinical practice, LIU Wansu proposed that fire-heat is the fundamental cause of stroke, and that the Six Climatic Factors and the Five Zhi-Emotions can all transform into fire. He further constructed a stratified syndrome differentiation and therapeutic system centered on clearing heat and purging fire, emphasizing differentiated treatment of exterior and interior syndromes, Six Meridians syndrome differentiation, and seasonally adjusted medication. This theory not only resolved the diagnostic and therapeutic dilemmas of febrile epidemic diseases during the Jin-Yuan period, but also exerted a profound influence on later physicians such as ZHANG Zihe and ZHU Danxi, thereby promoting the pluralistic development of stroke theory in traditional Chinese medicine (TCM). Modern pharmacological research provides solid scientific evidence, confirming that the ''fire-heat'' pathological state is highly associated with key mechanisms such as excessive inflammatory responses, oxidative stress, and excitatory amino acid toxicity following cerebral ischemia. Heat-clearing and fire-purging prescriptions and agents, such as Huanglian Jiedu Tang and baicalin, can exert multi-target neuroprotective effects by regulating inflammatory signaling, enhancing antioxidant enzyme activity, and balancing neurotransmitters. This not only verifies the scientific basis of the ''fire-heat inducing stroke'' theory from a modern biological perspective but also provides conclusive evidence for the clinical application of heat-clearing and fire-purging therapy. LIU Wansu's ''fire-heat inducing stroke'' theory represents a major milestone in the historical understanding of stroke pathogenesis, and its academically transitional insights continue to hold core guiding value for the pattern identification and treatment of ischemic stroke today.

ObjectiveTo construct a multifunctional liposomal delivery system by replacing cholesterol(Chol) in conventional liposomes with saikosaponin D(SSD) and modifying with poloxamer 407(P407) for co-delivery of curcumin(Cur). The system was evaluated for in vivo tumor targeting and inhibitory effects on mouse subcutaneous solid tumors. MethodsSingle-factor and orthogonal tests combined with information entropy weighting were used to optimize the formulation process of the liposome with encapsulation efficiency and absolute Zeta potential as indexes, and validation studies and liposomal characterization were performed. A subcutaneous solid tumor model was established by injecting H22 hepatocellular carcinoma cells subcutaneously into the dorsal surface of the right forelimb of mice. DiR-loaded traditional Chol liposomes(P407-DiR-Chol-LPs, PDCL) and novel SSD-based liposomes(P407-DiR-SSD-LPs, PDSL) were prepared by the optimized formulation process, and tail vein injection was performed to investigate the impact of SSD on liposome tumor targeting with small animal in vivo imaging. Mice were randomly divided into eight groups, including blank group, model group, free doxorubicin(DOX) group(2 mg·kg-1), free Cur group(8 mg·kg-1), free SSD group(10 mg·kg-1), P407-Cur-Chol-LPs(PCCL) group, P407-SSD-LPs(PSL) group, and P407-Cur-SSD-Lps(PCSL) group. Treatments were administered intraperitoneally every other day for seven doses. Antitumor efficacy and biocompatibility were evaluated by monitoring body weight change, organ indices, tumor volume and mass, relative tumor proliferation rate(T/C), and tumor growth inhibition rate(TGI). Histopathological analysis of liver, kidney, and tumor tissues was performed using hematoxylin-eosin(HE) staining. Serum levels of aspartate aminotransferase(AST), alanine aminotransferase (ALT), blood urea nitrogen(BUN), and creatinine(Crea)in mice were quantified by fully automated biochemical analyzer. ResultsOrthogonal test yielded optimal ratios of Cur, SSD, and P407 to soybean phosphatidylcholine(SPC) as 1∶25, 1∶20, and 1∶4. The optimized PCSL exhibited spherical morphology with a particle size of 179.15 nm, a Zeta potential of -47.25 mV, and an encapsulation efficiency of 96.40%. Its in vitro release profile conformed to first-order kinetics, demonstrating excellent storage stability and hemocompatibility. In vivo imaging revealed that the fluorescence signal in tumor tissues and the fluorescence intensity ratio between tumors and organs were significantly higher in the PDSL group than in the PDCL group(P<0.05, P<0.01). Among the treatment groups, PCSL group showed superior efficacy over free Cur group, free SSD group, PCCL group, and PSL group, with TGI>40% and T/C<60%, indicating pronounced anti-hepatocellular carcinoma effects(P<0.05, P<0.01). Histopathology and serum biochemistry indicated minimal hepatorenal toxicity and improved hepatic and renal function in PCSL-treated mice. ConclusionReplacing Chol with SSD in preparing multifunctional drug delivery systems not only stabilizes liposomes but also yields superior anti-hepatocellular carcinoma efficacy, achieving the effect of drug-excipient integration. Co-delivery of Cur via this system can be used for treating subcutaneous solid tumors in hepatocellular carcinoma, providing new insights and technical approaches for anti-hepatocellular carcinoma research and the meridian-guiding and messenger-directing theory in traditional Chinese medicine.

ObjectiveTo investigate whether Huanglian Jiedutang (HLJD) and its major active constituents (geniposide, baicalin, and berberine) can inhibit the inflammatory response of BV2 cells under lipopolysaccharide (LPS) stimulation via the high-mobility group protein B1 (HMGB1)/Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway, and to explore differences in therapeutic efficacy among the three monomers, their combined formula, and HLJD under equal content ratios. MethodsBV2 microglial cells were used as the primary experimental model. Cell viability was assessed using the cell counting kit-8 (CCK-8) method to examine the effects of different concentrations of dimethyl sulfoxide (DMSO, 0.8%, 0.4%, 0.2%, 0.1%, and 0.05%) on cell viability. IncuCyte was employed to monitor the growth of cells under different concentrations of HLJD (200, 100, 50, 25, 12.5, 6.25 mg·L-1). Nitric oxide (NO) assay was used to screen the optimal HLJD concentration. High-performance liquid chromatography (HPLC) determined the content of geniposide, baicalin, and berberine in HLJD, and experimental groups were subsequently established according to the relative proportions of these constituents. CCK-8 assay evaluated cell viability under different treatments. Enzyme-linked immunosorbent assay (ELISA) measured levels of inflammatory factors (TNF-α, IL-1β, IL-6, IL-10) in the supernatant. Flow cytometry assessed the effects of treatments on M1-type polarization of BV2 cells. Western blot determined the expression levels of HMGB1, TLR4, and NF-κB-related proteins. ResultsCompared with the blank group, DMSO at concentrations ≤0.2% did not affect cell viability within 48 h. BV2 cell growth plateaued at 24 h after treatment with 200 mg·L-1 HLJD. Under stimulation with 2 mg·L-1 LPS, this concentration of HLJD effectively reduced NO release, and 6 h pre-treatment had a stronger inhibitory effect on NO than direct administration. HPLC results showed that 1 mg of HLJD freeze-dried powder contained approximately 24 μg of geniposide, 15 μg of baicalin, and 30 μg of berberine. Based on these ratios, experimental groups were blank, LPS (2 mg·L-1), HLJD (200 mg·L-1), monomer combination, geniposide (4.8 mg·L-1), baicalin (3 mg·L-1), and berberine (6 mg·L-1). The monomer combination group consisted of all three active constituents dissolved together. LPS and HLJD or its active constituents did not affect cell viability compared with the blank group. LPS significantly increased TNF-α, IL-1β, IL-6, and IL-10 in the supernatant (P<0.01). HLJD and its active constituents significantly reduced pro-inflammatory factors TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01) while upregulating anti-inflammatory IL-10 (P<0.01), with the monomer combination showing the strongest effect (P<0.05, P<0.01). Compared with the blank group, LPS significantly increased the proportion of CD80⁺CD86⁺ (M1-type) BV2 cells (P<0.01). HLJD and its constituents partially inhibited M1 polarization (P<0.05, P<0.01), with the monomer combination exhibiting the most pronounced effect (P<0.05, P<0.01). Compared with the blank group, LPS upregulated HMGB1, TLR4, and NF-κB-related proteins (P<0.01), whereas HLJD and its active constituents significantly reduced their expression (P<0.05, P<0.01), with the monomer combination having the strongest regulatory effect (P<0.05, P<0.01). ConclusionHLJD and its major active constituents (geniposide, baicalin, berberine) can inhibit LPS-induced inflammatory responses in BV2 cells. The combination of the three active constituents demonstrates the most potent anti-inflammatory effect, significantly attenuating M1-type polarization of BV2 cells via the HMGB1/TLR4/NF-κB signaling pathway.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Objective: To analyze the demographic evolution of China over the forthcoming decade (2026-2035) and to systematically evaluate its potential implications for voluntary blood donation practices and the equilibrium of clinical blood supply and demand. Methods: Leveraging comprehensive blood collection and utilization data from 2021 to 2025 at the national, provincial (Shandong), and municipal (Zibo) levels, we identified and examined critical determinants influencing blood management systems. The DeepSeek-V3.2 large language model was deployed to project future population age structures, and to generate quantitative estimates for hospitalization volumes, clinical blood requirements, available blood supply, and donation frequencies for the target years 2030 and 2035, thereby furnishing an evidence base for strategic planning and priority-setting. Results: DeepSeek-derived projections indicate that the proportion of China's population aged 60 years and above will surpass 27% (370 million/1 380 million) by 2030 and exceed 30% (400 million/1 350 million) by 2035, signaling a marked acceleration in population aging. This demographic shift is projected to reduce the proportion of the national population eligible to donate blood from 59.2% (835 million out of 1.41 billion) to 52% (710 million out of 1.36 billion), while the demand for blood is expected to increase by 87.8% relative to 2024, rising from 26.927 million units to 50.56 million units. Sustaining blood supply-demand balance will necessitate progressive annual increases in donation rates. Under prevailing policy frameworks, the required blood donation rate among the eligible population in Shandong Province would need to rise by 122.57% by 2035 [from 20.07‰ (1.1641 million person-times/58 million people) to 44.67‰ (2.189 million person-times/49 million people)] to potentially satisfy projected clinical requirements. Conclusion: By integrating DeepSeek-V3.2, AI predictive models, and blood donation incentive measures, it is possible to monitor population demographics, forecast clinical blood demand, manage blood supplies, and ensure the long-term sustainability of clinical blood availability. It must be acknowledged, however, that the present analysis is constrained by a limited data foundation (comprising only five annual observation points); accordingly, the projections should be interpreted as directional trend indicators or methodological illustrations rather than definitive quantitative forecasts.

Background: Visual impairment is increasingly prevalent, underscoring the need for effective prevention strategies. This study investigated the association between cardiovascular health and visual impairment using three progressively developed metrics: Life’s Simple 7 (LS7), a cardiovascular health score developed by the American Heart Association based on 7 components, including physical activity, smoking status, body mass index (BMI), diet, blood glucose, blood pressure, and total cholesterol; Life’s Essential 8(LE8), which adds sleep health as an additional component; and Life’s Crucial 9 (LC9), which further incorporates mental health. We aimed to evaluate whether these expanded metrics provide additional explanatory value and to inform future public health strategies. Objective: To investigate the associations among LS7, LE8, and LC9 cardiovascular health scores and visual impairment in National Health and Nutrition Examination Survey 2013 to 2018, assess the added value of sleep and mental health components, and identify key contributing subcomponents using regression and machine learning methods. Methods: We analyzed data from 9891 participants in the 2013 to 2018 National Health and Nutrition Examination Survey. Multivariable logistic regression, restricted cubic spline modeling, and subgroup analyses were conducted to evaluate the association between cardiovascular health and visual impairment. Machine learning methods, including Random Forest and SHapley Additive exPlanations, a model interpretation approach used to assess feature importance, were applied. The Boruta algorithm, a feature selection method, was used to identify key subcomponents of cardiovascular health. Results: Participants with visual impairment were older, had lower poverty-to-income ratios, and exhibited lower cardiovascular health scores (LS7, LE8, and LC9). Higher cardiovascular health scores were negatively associated with visual impairment. Each one standard deviation increase in LS7, LE8, and LC9 was associated with approximately 8%, 2%, and 3% lower odds of visual impairment, respectively. LS7 showed the strongest negative association, whereas LE8 and LC9 emerged as the most important predictors in the machine learning models. Key subcomponents such as blood glucose, blood pressure, and BMI, as well as mental health status, were strongly associated with visual impairment. Conclusion: Higher cardiovascular health scores were negatively associated with visual impairment. LS7 demonstrated the strongest statistical association, whereas LE8 and LC9 were the most influential features in the machine learning models. Blood glucose, blood pressure, BMI, and mental health status were important correlates of visual impairment. From the perspective of the “prevention and treatment of diseases” in traditional Chinese medicine and the holistic concept, the aforementioned research findings confirm that severe visual impairment is indeed an external manifestation of overall health imbalance (such as organ dysfunction and Qi deficiency and blood stasis). The prevention strategy lies in comprehensively adjusting lifestyle, emotional factors, and metabolic indicators (corresponding to the key factors in the study) to restore the body’s internal balance and achieve prevention before disease arises.

ObjectiveTo investigate the effects of paeoniflorin (PF) on neuroinflammation and cognitive impairment in the rat model of Alzheimer's disease (AD) and to clarify whether its mechanism is associated with regulation of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. MethodsGlycosides related to AD-associated neuroinflammation were screened through bibliometric analysis, and the potential targets of PF were predicted through network pharmacology and molecular docking. A rat model of AD was established by intraperitoneal injection of D-galactose (100 mg·kg-1·d-1). Rats were assigned into a control group, a model group, a PF (200 mg·kg-1) group, and a donepezil (0.5 mg·kg-1·d-1) group, and drugs were administered by gavage for 21 days. The learning and memory abilities were evaluated by the Morris water maze (MWM). Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe hippocampal neuronal morphology. The mRNA levels of inflammatory factors were determined by Real-time quantitative polymerase chain reaction (Real-time PCR), and the protein levels of molecules in the JAK2/STAT3 signaling pathway were determined by Western blot. ResultsCompared with the control group, the model group showed prolonged escape latency and decreased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), accompanied by increased expression of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), as well as elevated ratios of phosphorylated (p)-JAK2/JAK2 and p-STAT3/STAT3 (P<0.01). Compared with the model group, the PF group and donepezil group exhibited shortened escape latency and increased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), decreased expression levels of IL-1β and TNF-α, upregulated mRNA levels of interleukin-4 (IL-4) and interleukin-10 (IL-10), and reduced ratios of p-JAK2/JAK2 and p-STAT3/STAT3 (P<0.05, P<0.01). ConclusionPaeoniflorin can alleviate cognitive impairment and neuroinflammation in the rat model of AD by inhibiting the JAK2/STAT3 signaling pathway.

OBJECTIVE To provide an experimental basis for quality control, clinical application and development of hepatoprotective drugs derived from Thesium chinense Turcz.METHODS Network pharmacology was adopted to predict and screen potential hepatoprotective constituents and their action targets of T. chinense Turcz. A liver-injured model of transgenic zebrafish Tg ( fabp10a : dsRed ) with fluorescent-labeled liver was induced by 4 mmol/L isoniazid. The relative liver fluorescence area and relative fluorescence intensity of zebrafish larvae, as well as the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutathione (GSH) and interleukin-6 (IL-6) were taken as indexes to evaluate the hepatoprotective activity of potential active constituents. High-performance liquid chromatography was used to determine the contents of hepatoprotective active constituents in 17 batches of T. chinense Turcz. medicinal materials from different producing areas.RESULTS Four potential hepatoprotective constituents including kaempferol-3- O -glucorhamnoside (KOG), kaempferol-3,7-di- O -glucoside (KDG), buddleoside (BUD) and apigenin-5- O -neohesperidoside (AON) were screened out via network pharmacology, and their core targets involved mitogen-activated protein kinase 1, nuclear factor-κB subunit 1, etc. Pharmacodynamic verification results showed that 25 μmol/L KOG, BUD, AON and 50 μmol/L KDG could significantly increase the relative liver fluorescence area and relative fluorescence intensity of liver-injured model larvae ( P <0.05), reduce the levels of AST, ALT and IL-6 ( P <0.05), and elevate the GSH level ( P <0.05). Content determination results indicated that KOG could be detected in all 17 batches of T. chinense Turcz. medicinal materials, with contents ranging from 0.097 0 to 8.082 0 mg/g;KDG, AON and BUD were not detected in partial batches of samples, and their contents in detectable batches were 0.019 3-0.123 2 mg/g, 0.018 4-0.109 1 mg/g and 0.385 1-1.189 3 mg/g, respectively.CONCLUSIONS KOG, KDG, AON and BUD in T.chinense Turcz. may be its potential hepatoprotective active constituents. Among them, KOG can be detected in T.chinense Turcz. medicinal materials from different producing areas with relatively high content, which can be used as the main marker constituent for evaluating the hepatoprotective effect of T.chinense Turcz.
