In this paper， by referring to ancient and modern literature， the textual research of Inulae Flos has been conducted to clarify the name， origin， production area， quality evaluation， harvesting， processing and others， so as to provide reference and basis for the development and utilization of famous classical formulas containing this herb. After textual research， it could be verified that the medicinal use of Inulae Flos was first recorded in Shennong Bencaojing of the Han dynasty. In successive dynasties， Xuanfuhua has been taken as the official name， and it also has other alternative names such as Jinfeicao， Daogeng and Jinqianhua. The period before the Song and Yuan dynasties， the main origin of Inulae Flos was the Asteraceae plant Inula japonica， and from the Ming and Qing dynasties to the present， I. japonica and I. britannica are the primary source. In addition to the dominant basal species， there are also regional species such as I. linariifolia， I. helianthus-aquatili， and I. hupehensis. The earliest recorded production areas in ancient times were Henan， Hubei and other places， and the literature records that it has been distributed throughout the country since modern times. The medicinal part is its flower， the harvesting and processing method recorded in the past dynasties is mainly harvested in the fifth and ninth lunar months， and dried in the sun， and the modern harvesting is mostly harvested in summer and autumn when the flowers bloom， in order to remove impurities， dry in the shade or dry in the sun. In addition， the roots， whole herbs and aerial parts are used as medicinal materials. In ancient times， there were no records about the quality of Inulae Flos， and in modern times， it is generally believed that the quality of complete flower structure， small receptacles， large blooms， yellow petals， long filaments， many fluffs， no fragments， and no branches is better. Ancient processing methods primarily involved cleaning， steaming， and sun-drying， supplemented by techniques such as boiling， roasting， burning， simmering， stir-frying， and honey-processing. Modern processing focuses mainly on cleaning the stems and leaves before use. Regarding the medicinal properties， ancient texts describe it as salty and sweet in taste， slightly warm in nature， and mildly toxic. Modern studies characterize it as bitter， pungent， and salty in taste， with a slightly warm nature. Its therapeutic effects remain consistent across eras， including descending Qi， resolving phlegm， promoting diuresis， and stopping vomiting. Based on the research results， it is recommended that when developing famous classical formulas containing Inulae Flos， either I. japonica or I. britannica should be used as the medicinal source. Processing methods should follow formula requirements， where no processing instructions are specified， the raw products may be used after cleaning.

Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Objective To explore the relationship between serum Niemann-pick type C1 like protein1(NPC1L1)and propro-tein convertase subtilisin/kexin type 9(PCSK9)levels and the risk of type 2 diabetes mellitus(T2DM)in Mongolian residents.Methods A total of 72 Mongolian patients with T2DM treated in Peking University Cancer Hospital,Inner Mongolia Hospital and the Affiliated Hospital of Inner Mongolia Medical University from June 2022 to June 2024 were selected as the T2DM group,and 81 healthy people in the same period were selected as the control group.LASSO model and multivariate Logistic regression model were used to screen the risk factors of disease onset.Multiple linear regression was used to analyze the correlation between NPC1L1 and PCSK9 levels and insulin function.Restricted cubic spline(RCS)model was used to analyze the dose-response relationship between NPC1L1 and PCSK9 levels and the incidence of T2DM,and explored the interaction between NPC1L1 and PCSK9 levels on the incidence of T2DM.Results NPC1L1(3.11±0.80 ng/L)and PCSK9(10.63±0.79 ng/L)in T2DM group were significantly higher than those in the control group(0.52±0.22 ng/L,3.21±0.17 ng/L),and the differences were statisti-cally significant(t=27.982,82.443,all P<0.05).NPC1L1(OR=2.458,95%CI=2.364～2.594,P<0.05)and PCSK9(OR=2.905,95%CI=2.541～3.528)were risk factors for T2DM(all P<0.001).The results of multiple linear regression analysis showed that as NPC1L1 and PCSK9 levels increased,FINS,HbA1c,C-P and OGTT levels also increased accordingly.With the increase of NPC1L1 and PCSK9 levels,insulin function also decreased(all P<0.05).The results of RCS model showed that with the increase of NPC1L1 and PCSK9 levels,the probability of T2DM incidence also increased(χ2=22.334,25.537,all P<0.001).No significant interaction was found between NPC1L1,PCSK9 levels and islet function indexes(P>0.05).Conclusion The levels of NPC1L1 and PCSK9 are closely related to the risk of T2DM in Mongolian residents.With the increase of NPC1L1 and PCSK9 levels,the incidence probability of T2DM increases.

In order to establish a competitive chemiluminescent enzyme-linked immunoassay for rapid and quantitative detection of Senecavirus A antibodies,the polystyrene plate was coated with inactivated Senecavirus A antigen,and the monoclonal antibodies against Senecavirus A VP2 and VP3 proteins labeled by horseradish peroxidase(HRP)were used as the competitive enzymic anti-bodies of the antibodies in the serum samples.The standard curve of the calibrator prepared by di-lution of positive serum was drawn to achieve quantitative detection.The successfully established SVA competitive CLEIA reported the result within 45 minutes.The maximum dilution of 1∶2 048 for calibrator serum was still detectable with no cross-reaction with the standard positive serum of other five kinds of virus antigens such as foot-and-mouth disease.The coefficient of variation within batches was less than 10％,and the coefficient of variation between batches was less than 15％,which showed good repeatability and stability.The positive and negative coincidence rates were 95.30％and 97.57％,respectively,and the total coincidence rate was 96.88％,showing high consistency.The SVA competitive CLEIA assay established in this study can be used for the rapid quantitative detection of Senecavirus A antibodies,filling the gap in the domestic rapid quantitative detection of SVA antibodies.

Objective To evaluate the application of high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)in identifying high-risk features of intracranial atherosclerotic plaques,and to analyze the correlation between plaque characteristics and stroke recurrence under varying degrees of stenosis.Methods The data from 368 patients with intracranial atherosclerotic stenosis(ICAS)across two centers were retrospectively analyzed.Based on the degree of stenosis,all patients were categorized into mild-to-moderate stenosis group(luminal stenosis<70%,n=155)and severe stenosis group(luminal stenosis≥70%,n=213).HRMR-VWI images and clinical information of the patients were collected and analyzed,and the culprit plaques were quantitatively analyzed.Univariate and multivariate logistic regression analyses were employed to identify the risk factors for stroke recurrence,and the predictive performance was evaluated using the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results Higher normalized wall index(NWI)[odds ratio(OR)=1.082,95%confidence interval(CI)1.050-1.118,P<0.05]and the presence of intraplaque hemorrhage(IPH)(OR=1.843,95%CI 1.120-3.036,P<0.05)were risk factors for stroke recurrence in all patients.And these two factors were also significant in the mild-to-moderate stenosis group(NWI:OR=1.088,95%CI 1.009-1.186,P<0.05;IPH:OR=4.049,95%CI 1.227-16.065,P<0.05).A predictive model for stroke recurrence was constructed using the combination of IPH and NWI,with the best performance in the mild-to-moderate stenosis group(AUC=0.813,95%CI 0.723-0.906).Conclusion In patients with luminal stenosis<70%,the increase of NWI and the presence of IPH have been validated as significant and effective indicators for predicting stroke recurrence,demonstrating notable predictive performance.In contrast,among patients with luminal stenosis≥70%,the utility of plaque characteristics in predicting stroke recurrence is relatively lower,indicating that the correlation between plaque characteristics and stroke recurrence varies across different degrees of stenosis.
