OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Parkinson's disease（PD） is the second most common neurodegenerative disease in the world， which seriously affects the lives of patients. With the acceleration of aging process， the number of patients continues to rise. Its main pathological features are aggregation of α-synuclein and degenerative death of dopaminergic neurons in the substantia nigra. However， the pathogenesis of PD is still unclear. According to reports， the brain-derived neurotrophic factor（BDNF）/tyrosine kinase receptor B（TrkB） signaling pathway is highly expressed and activated in dopaminergic neurons in the substantia nigra， which is closely related to neurophysiological processes such as neurogenesis， synaptic plasticity， neuroinflammation， and oxidative stress. It plays an important role in the occurrence and development of PD. At present， the treatment methods of Western medicine for PD are mainly based on drugs such as levodopa and dopamine agonists to alleviate motor symptoms， but with the increase of dose， the adverse reactions are significantly enhanced. Traditional Chinese medicine（TCM） has attracted people to explore its therapeutic effects on PD due to its characteristics of homology of medicine and food， economy， minor adverse reactions and multi-target action. Therefore， this paper systematically reviews the role of BNDF/TrkB pathway in the pathogenesis of PD and the mechanism of TCM formulas， extracts and monomers in the treatment of PD by regulating the BNDF/TrkB pathway according to retrieving the latest research reports at home and abroad， so as to provide a reference for the clinical application of related TCM and the development of new drugs for PD.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Aim To investigate the anti-Zika virus(ZIKV)mechanism of diterpenoid compound 9 from Euphorbia helioscopia in vitro.Methods The cytotox-icity of compound 9 was evaluated using the CCK-8 as-say.A ZIKV-infected Vero cell model was established,and the antiviral activity was assessed through RT-qPCR,plaque assay,Western blot,and immunofluores-cence.Furthermore,the mechanism of action was elu-cidated using multi-cell line validation,nanoparticle tracking analysis,cellular thermal shift assay,and mo-lecular docking.Results In Vero cells,compound 9 exhibited an EC50 of(3.95±0.15)μmol·L-1 and a CC50 of(272.12±8.56)μmol·L-1,demonstrating significantly higher antiviral efficacy than the positive control drug ribavirin(RBV).Its virus inactivation effect was time-dependent and could significantly re-duce viral load and plaque formation.Studies revealed that compound 9 altered the physicochemical properties of ZIKV particles,including reducing surface charge and increasing particle size distribution.Additionally,it significantly enhanced the thermal stability of the prM protein.Molecular docking analysis indicated that compound 9 formed a high-affinity interaction with the prM protein(binding energy:-38.52 kJ·mol-1)and stabilized its structure through hydrophobic interac-tions.Conclusion Compound 9 exerts in vitro anti-ZIKV activity by directly inactivating the virus,disrup-ting viral particle integrity,and targeting the prM pro-tein.

Based on the theories of "pathogenesis caused by constraint emotions" and "visceral orifices"， it is believed that the pathogenesis of tinnitus caused by constraint syndrome follows the evolution pattern of "qi constraint （liver qi constraint） → fire disturbance （liver constraint transforming into fire） → deficiency impairment （liver constraint with spleen deficiency） → blood stasis （liver constraint leading to blood stasis）". The treatment is guided by the principle of integrated internal and external therapy with harmonization of both body and mind. Internally， the treatment focuses on rectifying zang-fu imbalances， primarily using the Xiaoyao Powder （逍遥散）， with modifications based on syndrome differentiation. External therapies aim to unblock the meridians and orifices， commonly using auricular acupressure and Chinese herbal hot compresses. Additionally， traditional Chinese five-tone music therapy is applied to regulate emotional and mental disturbances. By integrating these three approaches， a comprehensive treatment strategy is formed that harmonizes both body and mind for managing tinnitus associated with constraint syndrome.

Objective:To understand the relationship between sleep duration and cardiovascular and metabolic comorbidities (CMM) in middle-aged and elderly people in China.Methods:This study was a prospective cohort study, based on the data of China Health and Retirement Tracing Survey (CHARLS) from 2011 to 2015, and included middle-aged and elderly people aged≥45 years in the cohort study. Age, gender, marital status, residence, education, smoking status, alcohol status, body mass index, history of diabetes, history of dyslipidemia, history of hypertension, history of stroke, history of heart disease, history of mental illness, depression scale score were collected. Multivariate logistic regression was used to analyze the association between daily sleep duration and the risk of CMM onset and to construct four models with stepwise adjusted covariates. A stratified analysis was established based on demographic factors, lifestyle factors, metabolic factors, cardiovascular and cerebrovascular factors, and psychological factors. Meanwhile, a subgroup analysis was established according to different combinations of cardiovascular and metabolic diseases to explore the association between sleep length and the risk of CMM in different populations.Results:A total of 297 (4.4%) of the 6 788 included participants experienced CMM. In the multivariate logistic regression, the RR value (95% CI) for the risk of CMM for>9 h was 1.99 (1.86-2.08) and 1.78 (1.64-1.92), respectively (all P<0.001). The stratified analysis showed that the risk of CMM incidence between sleep duration<7 h and>9 h was associated in people with different age, sex, residence, smoking status, drinking status, body mass index, hypertension, hypertension, diabetes, heart disease, stroke, dyslipidemia, and depression (all P<0.05). Subgroup analysis showed that sleep duration<7 h with both diabetes, heart disease and stroke had the highest risk of CMM ( RR=1.95, 95% CI: 1.65-2.14). Conclusion:In the middle-aged and elderly group in China, there is a U-shaped association between sleep duration and CMM, that is, insufficient or too long sleep duration throughout the day is related to the increased risk of CMM.

Objective:To investigate the correlation between the ratio of apolipoprotein B to apolipoprotein A-I (ApoB/ApoA-I) and unstable carotid plaque in a neurologically healthy population receiving health check-ups.Methods:This cross-sectional study consecutively enrolled 1 149 neurologically healthy individuals who underwent physical examinations at the Health Management Centre of Beijing Tiantan Hospital, Capital Medical University, from October 2021 to September 2022. All eligible participants completed standardized questionnaires, physical examinations and laboratory tests. Laboratory tests of lipid metabolism-related biomarkers included total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), ApoA-I, and ApoB; non-high-density lipoprotein cholesterol and the ApoB/ApoA-I ratio were subsequently calculated. The carotid plaque stability was evaluated using superb microvascular imaging technology. The participants were classified into unstable plaque group (341 cases) and stable plaque group (808 cases) according to the presence or absence of intraplaque neovascularization. The univariate and multivariate logistic regression analyses were used to explore the correlation between the ApoB/ApoA-I ratio and unstable carotid plaques.Results:The study enrolled 1 149 participants totally, with a median age of 57 (49-63) years, including 771 males (67.10%) and 378 females (32.90%), and 341 cases (29.68%) were found with unstable carotid plaques. The unstable plaque group had a higher proportion of males, smoking history, diabetes history, along with higher waist-to-hip ratio and ApoB/ApoA-I ratio compared to the stable plaque group [76.54% vs 63.12%, 33.43% vs 22.77%, 19.06% vs 13.37%, 0.91 (0.85, 0.94) vs 0.89 (0.84, 0.93), 0.64 (0.51, 0.76) vs 0.59 (0.48, 0.72)], while HDL-C and ApoA-I levels were lower [1.39 (1.19, 1.63) vs 1.44 (1.24, 1.66) mmol/L, 1.43 (1.29, 1.60) vs 1.51 (1.36, 1.68) g/L] (all P<0.05). An elevated ApoB/ApoA-I ratio was positively associated with the risk of unstable carotid plaque ( OR=1.61, 95% CI: 1.13-2.29, P=0.008; P for trend<0.001). After adjusting for age, gender, waist-to-hip ratio, history of hypertension, history of diabetes, dyslipidemia, cardiovascular disease, history of smoking and estimated glomerular filtration rate, the positive association between elevated ApoB/ApoA-I ratio and the risk of unstable carotid plaque remained significant ( OR=1.48, 95% CI: 1.01-2.16, P=0.044; P for trend=0.004). Conclusion:In a neurologically healthy population receiving health check-ups, an elevated ApoB/ApoA-I ratio may increase the risk of unstable carotid plaque.

Objective:To analyze the mediating effect of the inflammation on the sex differences in cognitive function among middle-aged and elderly individuals receiving health checkups.Methods:This cross-sectional study consecutively collected data from 757 middle-aged and elderly individuals receiving health checkups at Beijing Tiantan Hospital, Capital Medical University between January 1, 2023 and December 31, 2023. The gender, age, body mass index (BMI), waist to hip ratio (WHR), educational years, medical history and personal history were collected. The Montreal Cognitive Assessment (MoCA) were performed to assess the cognitive function. Inflammation indicators included the single blood inflammatory markers [white blood cell (WBC), high sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, and erythrocyte sedimentation rate (ESR)], inflammatory markers derived from blood cell counts, including neutrophil-lymphocyte ratio (NLR), derived neutrophil-lymphocyte ratio (dNLR), monocyte-to-lymphocyte ratio (MLR), neutrophil-monocyte to lymphocyte ratio (NMLR), systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), and aggregate index of systemic inflammation (AISI); and inflammatory markers derived from blood cell counts and high-density lipoprotein cholesterol (HDL-C), including neutrophil to HDL-C ratio (NHR), monocyte to HDL-C ratio (MHR), lymphocyte to HDL-C ratio (LHR), and platelet to HDL-C ratio (PHR) were all recorded. The simple mediation effect model in the SPSS 29.0 PROCESS macro was used to analyze the mediation effects of the inflammation indicators on the gender differences in cognitive function among middle-aged and elderly individuals receiving health checkups.Results:Among the 757 health checkup population in the final analysis, 466 were male (61.56%), and 291 were female (38.44%), with a mean age of (54.24±8.42) years. The male had higher BMI, WHR, educational years, frequency of hypertension and diabetes mellitus, MoCA scores, and inflammation indicators, including hs-CRP, WBC, NLR, MLR, NMLR, SIRI, AISI, NHR, MHR, LHR and PHR than those in the female [(26.41±3.20) vs (24.32±3.06) kg/m 2, (0.93±0.05) vs (0.83±0.06), 12 (9, 16) vs 11 (8, 15) years, 37.77% vs 21.31%, 16.52% vs 8.93%, 26 (24, 28) vs 26 (22, 28) points, 0.81 (0.38, 1.61) vs 0.63 (0.27, 1.63) mg/L, 5.75 (4.96, 6.78) vs 5.08 (4.27, 6.05)×10 9/L, 2.06 (1.67, 2.64) vs 1.87 (1.50, 2.37), 0.21 (0.17, 0.25) vs 0.17 (0.13, 0.21), 2.26 (1.84, 2.88) vs 2.02 (1.68, 2.55), 0.71 (0.51, 1.01) vs 0.49 (0.35, 0.67), 153.43 (108.91, 220.63) vs 113.34 (78.06, 164.27), 0.16 (0.12, 0.20) vs 0.11 (0.08, 0.14), 0.02 (0.01, 0.02) vs 0.01 (0.01, 0.01), 0.08 (0.06, 0.01) vs 0.06 (0.04, 0.07), 9.33 (7.82, 11.33) vs 8.36 (6.37, 10.21)] (all P<0.05). ESR and dNLR levels in the male were both lower than those in the female [6 (2, 11) vs 11 (6, 18) mm/h, 0.87 (0.85, 0.89) vs 0.89 (0.87, 0.91)] (both P<0.05). The MoCA score was negatively correlated with age, WHR, hs-CRP, IL-6, NLR, dNLR, NMLR, SIRI, NHR ( r=-0.355, -0.103, -0.115, -0.085, -0.094, -0.078, -0.093, -0.074, -0.108), and positively correlated with educational years ( r=0.512) (all P<0.05). After adjustment for confounding factors, including age, BMI, WHR, educational years, hypertension, and diabetes mellitus, dNLR and NHR mediated 13.11% and 12.80% association between gender and MoCA scores, respectively; after adjustment for above-mentioned confounders adding hs-CRP and IL-6, dNLR mediated 13.07% association between gender and MoCA score (all P<0.05), whereas no significant mediating effect was found of NHR on this association. Conclusions:Inflammation performed potential mediating effect on the association between sex difference and cognitive function among middle-to-old aged health checkup population, and the sex difference in cognitive function was partly mediated by the dNLR and NHR.

Emodin is a hydroxyanthraquinone compound that is widely distributed and has multiple pharmacological activities, including anti-diarrheal, anti-inflammatory, and liver-protective effects. Research indicates that emodin may be one of the main components responsible for inducing hepatotoxicity. However, studies on the mechanisms of liver injury are relatively limited, particularly those related to bile acids(BAs) metabolism. This study aims to systematically investigate the effects of different dosages of emodin on BAs metabolism, providing a basis for the safe clinical use of traditional Chinese medicine(TCM)containing emodin. First, this study evaluated the safety of repeated administration of different dosages of emodin over a 5-week period, with a particular focus on its impact on the liver. Next, the composition and content of BAs in serum and liver were analyzed. Subsequently, qRT-PCR was used to detect the mRNA expression of nuclear receptors and transporters related to BAs metabolism. The results showed that 1 g·kg~(-1) emodin induced hepatic damage, with bile duct hyperplasia as the primary pathological manifestation. It significantly increased the levels of various BAs in the serum and primary BAs(including taurine-conjugated and free BAs) in the liver. Additionally, it downregulated the mRNA expression of farnesoid X receptor(FXR), retinoid X receptor(RXR), and sodium taurocholate cotransporting polypeptide(NTCP), and upregulated the mRNA expression of cholesterol 7α-hydroxylase(CYP7A1) in the liver. Although 0.01 g·kg~(-1) and 0.03 g·kg~(-1) emodin did not induce obvious liver injury, they significantly increased the level of taurine-conjugated BAs in the liver, suggesting a potential interference with BAs homeostasis. In conclusion, 1 g·kg~(-1) emodin may promote the production of primary BAs in the liver by affecting the FXR-RXR-CYP7A1 pathway, inhibit NTCP expression, and reduce BA reabsorption in the liver, resulting in BA accumulation in the peripheral blood. This disruption of BA homeostasis leads to liver injury. Even doses of emodin close to the clinical dose can also have a certain effect on the homeostasis of BAs. Therefore, when using traditional Chinese medicine or formulas containing emodin in clinical practice, it is necessary to regularly monitor liver function indicators and closely monitor the risk of drug-induced liver injury.
