Neurological diseases have high morbidity and disability rates， posing a severe threat to human health. Cli nical manifestations include motor， sensory， cognitive and conscious disorders. Chaihu jia longgu muli decoction is derived from Treatise on Febrile Diseases ， with the effects of harmonizing Shaoyang， activating Yang and clearing heat， and tranquilizing the mind. This paper systematically reviews the research progress in clinical application and mechanism of Chaihu jia longgu muli decoction in the field of neurological diseases. It has been found that the decoction shows favorable efficacy in various neurological diseases such as insomnia， depression， epilepsy， vertigo， migraine and vascular dementia. The specific mechanisms are related to regulating neurotransmitter levels， repairing neuronal function， alleviating neuroinflammation， improving mitochondrial dysfunction and regulating intestinal flora. In the future， standardized prospective follow-up cohorts should be established， and core outcome indicators should be clearly defined to strengthen the evidence base. Furthermore， multidisciplinary research should be leveraged to expand the therapeutic value of Chaihu jia longgu muli decoction in the management of neurological diseases.

The European Association for Cardio-Thoracic Surgery (EACTS) has recently updated and published the "2024 EACTS guidelines on perioperative medication in adult cardiac surgery". Based on the latest evidence, the guidelines have been updated in multiple aspects including underlying disease management, antithrombotic medication, arrhythmia treatment and other supportive care, etc. This paper aims to summarize and interpret the guidelines, in order to promote clinicians’ understanding and optimize perioperative medical treatment in adult cardiac surgery.

As a common medical condition， vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic （Huang Di Nei Jing）， this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend， resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend， which disturbs the clear orifices， thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement， the disorder of body fluid distribution， and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending， tonifying deficiency and purging excess， and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects： regulating Qi movement throughout the body， harmonizing the distribution of body fluids， and coordinating Yin and Yang as well as the interior and exterior， thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation， immunomodulatory， and anti-tumor functions， which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension， stroke， otitis media， Meniere’s disease， and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three， thus providing new ideas for the syndrome differentiation and treatment of vertigo.

Objective To investigate the effect of four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction on serum neurotransmitters and neurological func-tion in patients with post-stroke cognitive impairment(PSCI).Methods A total of 110 patients with PSCI were randomly divided into treatment group and control group,with 55 cases in each group.The control group was treated with donepezil tablet,while the treatment group was treated with four tradi-tional Chinese drugs for reinforcing kidney and Tongqiao Huoxue Decoction on the basis of the control group.The total effective rate,the Mini-Mental State Examination(MMSE)score,the Montreal Cogni-tive Assessment(MoCA)score,the National Institutes of Health Stroke Scale(NIHSS)score and the Barthel Index(BI)as well as serum levels of acetylcholine(ACh),dopamine(DA),norepinephrine(NE),5-hydroxytryptamine(5-HT),neuron-specific enolase(NSE),visinin-like protein-1(VILIP-1),myelin basic protein(MBP),and heat shock protein 70(HSP70)before and after treatment were compared between the two groups.Adverse reactions in both groups were recorded.Results The total effective rate was 90.91％in the treatment group,which was significantly higher than 76.36％in the control group(P＜0.05).After treatment,the MMSE score,MoCA score and BI as well as serum levels of ACh,DA,NE,5-HT and HSP70 in the treatment group were significantly higher than those in the control group,while the NIHSS score and serum levels of NSE,VILIP-1 and MBP were significantly lower than those in the control group(P＜0.05).The total incidence rate of adverse reactions in the treatment group and the control group was 12.73％and 9.09％respectively,which showed no significant between-group difference(P＞0.05).Conclusion Four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction can promote the secretion of cognition-related neurotransmitters in patients with PSCI,accelerate the repair of neurological damage,and safety is relatively high.

Objective:To investigate the correlation between serum neuron-specific enolase (NSE) levels and poor neurological outcomes in cardiac arrest (CA) patients supported by veno-arterial extracorporeal membrane oxygenation (VA-ECMO).Methods:This retrospective analysis was conducted on adult CA patients treated with VA-ECMO at Hangzhou First People's Hospital Affiliated to Westlake University School of Medicine, and Second Affiliated Hospital Zhejiang University School of Medicine, from December 2018 to February 2024. General clinical data and serial serum NSE levels at 24, 48, and 72 h after ECMO initiation were collected. Based on the Glasgow-Pittsburgh Cerebral Performance Category (CPC) at discharge, patients were divided into poor neurological outcome group (CPC 3-5) and good neurological outcome group (CPC 1-2). Differences in serum NSE levels between the two groups were compared. The accuracy of serum NSE levels at three time points in predicting poor neurological outcomes in CA patients was assessed via receiver operating characteristic curves, and the optimal cut-off values were determined by the Youden index. Multivariate logistic regression analysis was performed to determine the relationship between serum NSE levels and poor neurological outcomes. Subgroup analysis was based on age, sex, location of CA, and extracorporeal cardiopulmonary resuscitation (ECPR).Results:A total of 120 eligible CA patients were included, with 88 patients (73.3%) having poor neurological outcomes at discharge. Serum NSE levels at 24, 48, and 72 h after ECMO initiation were higher in the poor outcome group compared to the good outcome group (all P<0.05). The serum NSE level at 72 h had the highest accuracy in predicting poor outcomes, with an area under the curve (AUC) of 0.91 (95% CI: 0.85-0.96), and a cut-off value of 42.0 μg/L. The AUCs for 24 and 48 h were 0.78 (95% CI: 0.69-0.86) and 0.87 (95% CI: 0.80-0.94), with cut-off values of 70.6 μg/L and 64.5 μg/L, respectively. Multivariate logistic regression analysis suggested that the serum NSE level at 72 h was associated with poor outcomes ( P<0.05), and an NSE level >42.0 μg/L was an independent risk factor for poor outcomes ( OR=20.29, 95% CI: 2.90-92.15). Subgroup analysis showed that serum NSE level at 72 h was an independent risk factor for poor neurological outcomes in CA patients aged<60 years old, male or female, out-of-hospital or in-hospital CA, and whether to perform ECPR (all P<0.05). Conclusion:Elevated serum NSE levels at 72 h after VA-ECMO initiation are associated with poor neurological outcomes in CA patients, with the cut-off value of 42.0 μg/L.

The management of chronic wounds presents significant challenges, characterized by a low rate of healing and substantial impairment of patients’ quality of life, while also exerting a considerable strain on healthcare resources. Wound healing is a multifactorial and dynamic process, necessitating close monitoring of wound changes and timely, appropriate interventions. Smart bandage/dressing, an innovative approach born from interdisciplinary research, offers a new generation of wound care. It enables dynamic quantitative monitoring of wound conditions; facilitates transdermal drug release and physical mode therapeutics; and adjusts interventions in real time based on monitoring outcomes. In comparison to traditional wound dressings, smart bandages exhibit attributes such as real-time responsiveness, precision, and convenience. They not only simplify wound management but also enhance patient comfort and compliance, showcasing potential as a safe and effective treatment modality. Smart bandages hold promise for elevating the efficiency of managing chronic wounds, reducing morbidity rates, alleviating the burden of disease, and ultimately improving patients’ quality of life. This paper summarized the recent research progress of smart bandages and provided insights into novel wound care strategies.

Ferroptosis has been shown to mediate the development of fibrosis.Polyphyllin Ⅶ(PP7),a bioactive component of Paris polyphylla,exhibits potent anti-inflammatory activity and can significantly alleviate liver fibrosis.In this study,treatment with PP7 significantly inhibited the proliferation and activation of hepatic stellate cells(HSCs),which could be suppressed by a ferroptosis inhibitor.In addition,it promoted HSC ferroptosis by suppressing glutathione(GSH)peroxidase 4(GPX4)and enhanced the expression of CX3C chemokine ligand 1(CX3CL1).Depletion of CX3CL1 attenuated the effects of PP7 on the activation and ferroptosis of HSCs and the expression of GPX4.Notably,CX3CL1 directly interacted with GPX4,triggering HSC ferroptosis.The transcription factor hypermethylated in cancer 1(Hic1),which binds to the Cx3cl1 promoter,increased the expression of CX3CL1.Its absence resulted in downregulation of CX3CL1,sup-pressing the GPX4-dependent ferroptosis of PP7-treated HSCs and promoting their activation.HIC1 was found to directly interact with PP7 at the GLY164 site.Co-culture experiments showed that PP7-induced HSC ferroptosis attenuated macrophage recruitment by regulating inflammation-related genes.HSC-specific inhibition of HIC1 counteracted PP7-induced collagen depletion and HSC ferroptosis in vivo.These findings suggest that PP7 induces HSC ferroptosis through the HIC1/CX3CL1/GPX4 axis.

Ferroptosis has been shown to mediate the development of fibrosis. Polyphyllin VII (PP7), a bioactive component of Paris polyphylla, exhibits potent anti-inflammatory activity and can significantly alleviate liver fibrosis. In this study, treatment with PP7 significantly inhibited the proliferation and activation of hepatic stellate cells (HSCs), which could be suppressed by a ferroptosis inhibitor. In addition, it promoted HSC ferroptosis by suppressing glutathione (GSH) peroxidase 4 (GPX4) and enhanced the expression of CX3C chemokine ligand 1 (CX3CL1). Depletion of CX3CL1 attenuated the effects of PP7 on the activation and ferroptosis of HSCs and the expression of GPX4. Notably, CX3CL1 directly interacted with GPX4, triggering HSC ferroptosis. The transcription factor hypermethylated in cancer 1 (Hic1), which binds to the Cx3cl1 promoter, increased the expression of CX3CL1. Its absence resulted in downregulation of CX3CL1, suppressing the GPX4-dependent ferroptosis of PP7-treated HSCs and promoting their activation. HIC1 was found to directly interact with PP7 at the GLY164 site. Co-culture experiments showed that PP7-induced HSC ferroptosis attenuated macrophage recruitment by regulating inflammation-related genes. HSC-specific inhibition of HIC1 counteracted PP7-induced collagen depletion and HSC ferroptosis in vivo. These findings suggest that PP7 induces HSC ferroptosis through the HIC1/CX3CL1/GPX4 axis.
