ObjectiveTo identify the pathogen species responsible for the wilt disease of Tetradium ruticarpum in Chongqing, investigate there biological characteristics, and screen effective fungicides, so as to provide a theoretical basis for disease control in production. MethodsThe pathogen was isolated via the tissue culture method. Pathogenicity was verified according to Koch's postulates. The pathogen was identified based on morphological characteristics and multi-gene phylogenetic analysis. The mycelial growth rate method was used for biological characterization of the pathogen and fungicide screening. ResultsThe pathogen colonies were nearly circular with irregular edges, white, short, velvety aerial hyphae, and pale purple undersides. Macroconidia were colorless, sickle-shaped, with 3-5 septa, while microconidia were transparent, elliptical, aseptate or with 1-2 septa. Multi-gene phylogenetic analysis showed that the pathogen clustered in the same clade as Fusarium fujikuroi with 100% support, which, combined with morphological characteristics, identified the pathogen causing wilt of T. ruticarpum in Chongqing as F. fujikuroi. The optimal conditions for the mycelial growth of F. fujikuroi were mung bean agar (MBA) with glucose as the carbon source, beef extract and yeast powder as nitrogen sources, 28 ℃, pH 7.0, and alternating light/dark conditions. The optimal conditions for sporulation were potato dextrose agar (PDA) with glucose as the carbon source, beef extract as the nitrogen source, 28 ℃, pH 7.0, and complete darkness. Among chemical fungicides, phenazine-1-carboxylic acid exhibited the strongest inhibitory effect on F. fujikuroi. Shenqinmycin and tetramycin were the most effective bio-fungicides. ConclusionThis study is the first to report F. fujikuroi as the causal agent of wilt disease in T. rutaecarpa. The chemical fungicide phenazine-1-carboxylic acid and the bio-fungicides shenqinmycin and tetramycin showed strong inhibitory effects against F. fujikuroi.

Objective:
To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control.
Methods:
Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence.
Results:
A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk.
Conclusions
SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

Parkinson's disease (PD) is a chronic progressive neurodegenerative disorder primarily characterized by motor dysfunction. The main pathological features include the loss of dopaminergic neurons in the substantia nigra, abnormal aggregation of alpha-Synuclein (α-Syn), and the formation of Lewy bodies. However, the exact mechanisms remain unclear. In recent years, the PD incidence has gradually increased, while current treatment methods are limited to symptom alleviation, incapable of halting disease progression, and prone to adverse effects, thus making it urgent to search for medicines effective for PD. Modern research indicates that the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor E2 related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway is closely related to oxidative stress, neuroinflammation, apoptosis, ferroptosis, and mitochondrial dysfunction, playing a crucial role in the pathophysiological development of PD. A large number of studies have further confirmed that traditional Chinese medicine (TCM) can regulate diseases through a holistic view of Syndrome differentiation and microscopic molecular pathways. With unique advantages, such as multiple targets, multiple pathways, and fewer adverse reactions, TCM provides a new strategy for PD treatment. This article elucidates the mechanism of the Keap1/Nrf2/ARE signaling pathway in the occurrence and development of PD, while summarizing the latest research on PD intervention by TCM monomers, active ingredients, and compounds, as well as acupuncture via the precise targeted regulation of the Keap1/Nrf2/ARE pathway, aiming to provide a reference for clinical medicine development to prevent and treat PD.

In the period of digital transformation of the medical service model, maintaining algorithm justice for medical artificial intelligence possesses multiple value implications. However, practical dilemmas exist at different stages of achieving this value goal. At the initial stage of diagnosis and treatment decision-making, there is a risk of imbalance in patients’ rights and interests, such as weakened effectiveness of patients’ right to informed consent, as well as low synergy between rights and interests protection and technological innovation. In the process of diagnosis and treatment decision-making, the algorithmic model is constrained by the technological bottleneck in the underlying application, deviating from the legal track of technological neutrality. After the diagnosis and treatment decision-making is generated, it triggers a crisis in the remedy of patients’ rights and interests and breeds the phenomenon of an ambiguous definition of subject qualification and attribution principle. In this regard, it is essential to establish a preemptive safeguard system focusing on the protection of patients’ rights and interests, set technological fairness standards, and shape review norms of technological neutrality. The aim is to ensure the equalization of remedy channels for patients’ rights and interests, promote the fairness in the proportion of responsibilities among multiple subjects, and thereby safeguard the digital justice in the field of intelligent diagnosis and treatments.

ObjectiveTo explore the correlation between the blood stasis score of coronary heart disease(CAD) and mild cognitive impairment(MCI), as well as the changes in plasma metabolic profile of blood stasis in patients with CAD combined with MCI(CADMCI) through a cross-sectional study, and further explore the impact of different degrees of blood stasis on the plasma metabolite profile of CADMCI patients. MethodsAccording to the diagnostic criteria of CAD and CAD blood stasis, patients hospitalized in Xiyuan Hospital of China Academy of Chinese Medical Sciences from October 2022 to October 2023 were continuously included. According to the Montreal Cognitive Assessment(MoCA) scale score, the enrolled patients were divided into CADMCI blood stasis group and CAD blood stasis group. The association between blood stasis score and MCI was analyzed by multivariate Logistic regression model. The receiver operating characteristic(ROC) curve was drawn, and the area under the curve(AUC) was calculated to evaluate the sensitivity and specificity of the model. According to the blood stasis score, the first 30 patients in the CADMCI blood stasis group and CAD blood stasis group were divided into mild blood stasis and severe blood stasis. Ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) was used to detect plasma metabolites in each group of patients. The differential metabolites were screened according to variable importance in the projection(VIP) value≥1, fold change(FC)<0.67 or >1.5, and P<0.05. ROC curve analysis was further used to evaluate the discriminatory efficiency of the screened differential metabolites for each group of samples. ResultsA total of 266 CAD patients were included in this study. Multivariate Logistic regression analysis showed that the CAD blood stasis score was significantly correlated with MCI[odds ratio(OR)=1.619, 95% confidence interval(CI) 1.223-2.142, P<0.001, ROC curve AUC was 0.615(95% CI 0.547-0.683, P=0.001)], indicating that the CAD blood stasis score has a certain predictive value for MCI. Plasma non-targeted metabolomics analysis showed that the main differential metabolites between CAD blood stasis and CADMCI blood stasis were lipid metabolites, among which phosphatidylcholine[20∶4(5Z, 8Z, 11Z, 14Z)/P-18∶1(11Z)] had the best discriminatory efficiency(ROC curve AUC=0.867, 95% CI 0.754-0.942). Further analysis of the differential metabolites between mild and severe blood stasis showed that lipid metabolites were also the main differential metabolites between mild and severe blood stasis. Among them, 1α,25-dihydroxy-2β-(2-hydroxyethoxy) vitamin D3 had the best efficacy in distinguishing mild and severe CAD blood stasis(AUC=0.813, 95% CI 0.649-0.951), and phosphatidylcholine 34∶2 had the best efficacy in distinguishing mild and severe CADMCI blood stasis(AUC=0.819, 95% CI 0.640-0.941). ConclusionThere is a significant correlation between CAD blood stasis score and MCI. Phosphatidylcholine metabolites play an important role in the pathogenesis of CADMCI blood stasis and severe blood stasis. The CAD blood stasis score combined with the detection of phosphatidylcholine metabolites can provide a reference for the development of early and efficient identification strategies for CADMCI.

ObjectiveIn order to provide a reference for the optimization of preparation process of stir-fried Glycyrrhizae Radix et Rhizoma(sf-GRR), the quality changes during the processing was studied. MethodsGlycyrrhizae Radix et Rhizoma was processed by stir-frying for 17 min, and samples were collected every 1 min during the processing. The appearance color of the samples was determined by visual analysis technology, the moisture and extract of the process samples were detected by the drying method and the hot extraction method of alcohol-soluble extract in the general rules of the 2020 edition of Chinese Pharmacopoeia(part Ⅳ), and the contents of liquiritin apioside, liquiritin, isoliquiritin apioside, isoliquiritin, licoricesaponin G2 and glycyrrhizic acid in the process samples were determined by high performance liquid chromatography(HPLC). Then principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA) and Spearman correlation analysis were used for clustering, discrimination and correlation analysis of the appearance color, moisture, extract and the contents of six internal components. Based on artificial neural network and random forest algorithm, the prediction model of processing degree of sf-GRR was established. On this basis, based on the five principles of quality marker(Q-Maker), explore the monitoring Q-Maker of sf-GRR. ResultsThe color of Glycyrrhizae Radix et Rhizoma deepened after stir-frying, and the appearance color of the sample changed from light yellow to dark yellow during processing. During the stir-frying process, the moisture content showed a decreasing trend with the extension of processing time, while the extract content showed an increasing trend with the extension of processing time. After stir-frying, the contents of liquiritin apioside, liquiritin and licoricesaponin G2 showed an overall decreasing trend, while the contents of isoliquiritin apioside and isoliquiritin increased, and the content of glycyrrhizic acid increased slightly. The correlation analysis showed that moisture was positively correlated with brightness(L*) and red/green value(a*), and negatively correlated with yellow/blue value(b*) and total color difference(E*ab). Isoliquiritin apioside and isoliquiritin had negative correlation with L* and a*, and positive correlation with b* and E*ab. The processing process of sf-GRR could be divided into two stages of the early stage(0-14 min) and the late stage(15-17 min), and could be divided into three stages of the early stage(0-6 min), the middle stage(7-14 min) and the late stage(15-17 min) by combining the moisture, extract, the contents of 6 components and color values. Based on artificial neural network analysis and random forest algorithm, isoliquiritin apioside, isoliquiritin, liquiritin and glycyrrhizic acid were selected as monitoring markers for sf-GRR. ConclusionBased on the analysis of the exterior-interior indicators of process samples of sf-GRR, this paper ultimately identifies four processing monitoring markers, which can provide a basis for optimizing the processing technology of sf-GRR.
