To summarise the clinical experience of treating insomnia with the method of resolving depression, regulating the middle, and tranquilising mind. It is believed that the key to the pathogenesis of insomnia lies in qi depression, disharmony of qi pivot, and disharmony of qi and blood, and the core treatment is to resolve depression, regulating the middle, and tranquilising mind. The self-prescribed Jieyu Anmian Formula (解郁安眠方) could be used as the basic treatment, then modified according to the performance of the patient and syndromes. For syndrome of liver depression restricting spleen, the treatment should soothe liver and invigorate spleen, resolve depression and regulate the middle; for syndrome of liver depression and phlegm coagulation, the treatment should resolve depression and phlegm, support the earth and free the wood; for syndrome of liver depression transforming into fire, the treatment should soothe liver and clear fire, resolve depression and dysphoria; for syndrome of qi stagnation and blood stasis, the treatment should activate blood and regulate the middle, resolve depression and tranquilise mind.

Objective: To compare the biological characteristics of human induced pluripotent stem cell-derived platelet exosomes (hiPSC-Plt-Exos) with those of conventional apheresis platelet exosomes (Plt-Exos), specifically focusing on their differential abilities to enhance the proliferation and migration of human umbilical cord mesenchymal stem cells (hUC-MSCs). Methods: Exosomes were isolated from hiPSC-derived Plt and apheresis Plt concentrate using size exclusion chromatography. These exosomes were then characterized through nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), and Western blotting. Co-culture experiments into hUC-MSCs were conducted with hiPSC-Plt-Exos and apheresis Plt-Exos, respectively. Their effects on the proliferation and migration of hUC-MSCs were assessed via cell proliferation assays and scratch tests. Results: hiPSC-Plt-Exos and apheresis Plt-Exos exhibited comparable particle sizes, morphological features (such as the characteristic cup-shaped structure), and surface markers (including CD9 and HSP70). Notably, hiPSC-Plt-Exos demonstrated a significantly greater ability to enhance the proliferation and migration of hUC-MSCs compared to apheresis Plt-Exos (P<0.05). These differences provide critical comparative data for their application in various clinical contexts. Conclusion: This study establishes a theoretical foundation for developing precise therapeutic strategies based on hiPSC-Plt-Exos. Furthermore, it underscores the necessity of selecting the appropriate type of exosomes according to the specific disease microenvironment to achieve optimal therapeutic outcomes.

Objective:This study aims to evaluate the quality and explore the preliminary clinical applications of a domestically developed hepatitis D virus nucleic acid quantification reagent (abbreviated as"domestic HDV RNA reagent").Methods:The sensitivity and accuracy of the reagent were evaluated in accordance with the WHO HDV RNA international standard, employing the Bio-Rad CFX Opus 96 real-time fluorescence quantitative PCR analysis system. Serial dilutions of pseudo-viruses or cell culture-derived virus were used to determine the linear range of the domestic HDV RNA reagent. Specificity was assessed using positive samples of HAV, HBV, HCV infection, and HEV national reference materials. Precision was evaluated with samples at both high and low concentrations. In a comparative analysis, 30 HDV IgG positive samples were tested using both the domestic HDV RNA reagent and the RoboGene HDV RNA kit based on the ABI 7500 FAST DX system. The Pearson correlation coefficient (r) was used to examine the correlation between the two reagents.Results:The domestic HDV RNA reagent demonstrated a high sensitivity of up to 6 IU/ml, consistent with that of the comparator reagent. The calibration curve for WHO HDV RNA standards had a slope of -3.286, with an amplification efficiency of 101.6%. The linear detection range spanned from 10 to 10 8 IU/ml for eight HDV genotypes. The domestic HDV RNA reagent exhibited exceptional specificity, without cross-reactivity observed with HAV, HBV, HCV, or HEV. Accuracy assessments at five concentration levels met the required standards, with intra-assay precision coefficient of variation ( CV) ranging from 1.20% to 4.20%, and inter-assay precision CV from 1.20% to 7.90%. The detection results for HDV IgG positive samples were highly correlated with the comparator reagent ( r=0.984, P<0.001), achieving a diagnostic accuracy of 100% compared to sequencing results. Conclusion:In this study, the domestic HDV RNA reagent possesses excellent specificity, accuracy, precision, and a broad linear range, attaining a sensitivity level on par with international reagents of the same type.

Objective To investigate the feasibility of developing a grading diagnostic model for schistosomiasis-induced liver fibrosis based on B-mode ultrasonographic images and clinical laboratory indicators. Methods Ultrasound images and clinical laboratory testing data were captured from schistosomiasis patients admitted to the Second People’s Hospital of Duchang County, Jiangxi Province from 2018 to 2022. Patients with grade I schistosomiasis-induced liver fibrosis were enrolled in Group 1, and patients with grade II and III schistosomiasis-induced liver fibrosis were enrolled in Group 2. The machine learning binary classification tasks were created based on patients’radiomics and clinical laboratory data from 2018 to 2021 as the training set, and patients’radiomics and clinical laboratory data in 2022 as the validation set. The features of ultrasonographic images were labeled with the ITK-SNAP software, and the features of ultrasonographic images were extracted using the Python 3.7 package and PyRadiomics toolkit. The difference in the features of ultrasonographic images was compared between groups with t test or Mann-Whitney U test, and the key imaging features were selected with the least absolute shrinkage and selection operator (LASSO) regression algorithm. Four machine learning models were created using the Scikit-learn repository, including the support vector machine (SVM), random forest (RF), linear regression (LR) and extreme gradient boosting (XGBoost). The optimal machine learning model was screened with the receiver operating characteristic curve (ROC), and features with the greatest contributions to the differentiation features of ultrasound images in machine learning models with the SHapley Additive exPlanations (SHAP) method. Results The ultrasonographic imaging data and clinical laboratory testing data from 491 schistosomiasis patients from 2019 to 2022 were included in the study, and a total of 851 radiomics features and 54 clinical laboratory indicators were captured. Following statistical tests (t = −5.98 to 4.80, U = 6 550 to 20 994, all P values < 0.05) and screening of key features with LASSO regression, 44 features or indicators were included for the subsequent modeling. The areas under ROC curve (AUCs) were 0.763 and 0.611 for the training and validation sets of the SVM model based on clinical laboratory indicators, 0.951 and 0.892 for the training and validation sets of the SVM model based on radiomics, and 0.960 and 0.913 for the training and validation sets of the multimodal SVM model. The 10 greatest contributing features or indicators in machine learning models included 2 clinical laboratory indicators and 8 radiomics features. Conclusions The multimodal machine learning models created based on ultrasound-based radiomics and clinical laboratory indicators are feasible for intelligent identification of schistosomiasis-induced liver fibrosis, and are effective to improve the classification effect of one-class data models.

By reviewing the research history on quality comparison between wild and cultivated Chinese crude drugs, this paper systematically combed the relevant research reports since the 1950s, and summarized and analyzed the results of existing comparative studies, and found that the existing comparative research on the quality of wild and cultivated Chinese crude drugs were mainly focused on several aspects, including characteristics, microstructures, chemical compositions, pharmacodynamic effects, and genetic diversity. Among these, comparative studies of chemical compositions have been the dominant approach, with a particular emphasis on comparing the contents of index components. However, research on pharmacodynamic effects remained relatively limited. Due to various factors such as sample quantity, sample origin, growth period and cultivation methods, the differences in quality between wild and cultivated Chinese crude drugs vary significantly. In general, most wild Chinese crude drugs exhibited higher quality than cultivated products, with significant differences in their characteristics. The contents and proportions of some chemical components underwent noticeable changes, particularly with a marked increase in the proportion of primary metabolites after cultivation. The quality of cultivated Chinese crude drugs is closely related to the cultivation practices employed. Chinese crude drugs produced through wild nurturing, simulated wild planting, ecological cultivation, and other similar methods demonstrate quality levels comparable to those of wild Chinese crude drugs. Based on the analysis results, it is recommended to explicitly specify the cultivation practices and cultivation period of cultivated Chinese crude drugs in comparative studies of the quality between wild and cultivated Chinese crude drugs. Multiple technical approaches, including characteristics, microscopy, non-targeted metabolomics combined with quantitative analysis of differential components, and bioefficacy evaluation, should be employed to comprehensively assess the quality disparities between wild and cultivated Chinese crude drugs. Moreover, research efforts should be intensified to investigate the changes in pharmacodynamic effects resulting from differences in plant cell wall composition, primary metabolites, and secondary metabolites, in order to guide the production of high-quality Chinese crude drugs.

Objective To explore the association of the magnitude of systolic blood pressure reduction(SBPr)with post-procedure 24 h symptomatic intracranial hemorrhage(sICH)and 90-day clinical outcomes in patients with successful endovascular thrombectomy(EVT).Methods Consecutively registered patients with EVT caused by anterior circulation large vessel occlusion stroke(LVOS)in the First Affiliated Hospital of Wannan Medical College(Yijishan Hospital)between July 2015 and April 2023 and patients with successful reperfusion were analyzed.Demographic data,medical history(hypertension,diabetes),the trial of Org 10172 in acute stroke treatment(TOAST)classification,the baseline National Institutes of Health Stroke Scale(NIHSS)score and the baseline Alberta stroke early CT(ASPECT)score of patients were collected.And procedure related parameters(including time from onset to puncture,time from onset to reperfusion,occluded site[internal carotid artery,M1 segment of middle cerebral artery,M2 segment of middle cerebral artery],collateral circulation status[determined based on preoperative occluded angiography showing the range of collateral circulation in the occluded vessel area,defined as good collateral circulation with a reflux range of ≥ 50%and poor collateral circulation with a reflux range of<50%]),immediate postoperative reperfusion status(evaluated using the modified thrombolysis for cerebral infarction[mTICI]grading,successful reperfusion defined as mTICI grading of 2b-3),24 hours sICH,and 90 days clinical outcomes(evaluated using the modified Rankin scale score at 90days after EVT,with a score ≤ 2indicating a good prognosis and a score>2indicating a poor prognosis).SBPr was defined as(baseline SBP-mean SBP)/baseline SBP x 100%.According to the the magnitude of SBPr,SBPr is divided into 5 categories(<-10%,-10%-10%,>10%-20%,>20%-30%and>30%).Based on the clinical outcomes at 90 days and the occurrence of sICH at 24 hours after EVT,patients were divided into a good prognosis group and a poor prognosis group,as well as an sICH group and a non-sICH group.The relationship between SBPr and postoperative 90 days clinical prognosis or sICH was analyzed using a binary Logistic regression model.Subgroup analysis was conducted based on a history of hypertension(yes and no),continuous intravenous hypotensive therapy(yes and no),baseline ASPECT scores(3-5 and 6-10),and collateral circulation status(good and bad).Using a restricted cubic plot to depict the relationship between SBPr and sICH and clinical prognosis at 90days.Results(1)In total,731 patients were included.The median age was 71(62,77)years and 424(58.0%)were men.The median baseline NIHSS score was 14(12,18),the median baseline ASPECT was 9(7,10),405(55.4%)patients achieved 90-day modified Rankin scale score 0-2,and 35 patients(4.8%)developed sICH.(2)Multivariate analysis showed that the older age(OR,1.036,95%CI 1.017-1.056),the higher baseline NIHSS score(OR,1.095,95%CI1.049-1.144),the lower baseline ASPECT score(OR,0.704,95%CI 0.636-0.780),diabetes(OR,1.729,95%CI 1.084-2.758),bad collateral circulation(good collateral circulation vs.bad collateral circulation,OR,0.481,95%CI 0.332-0.696)and SBPr>30%(SBPr-10%-10%as a reference,OR,2.238,95%CI 1.230-4.071),the higher the risk of poor clinical outcomes at 90 days(all P<0.05).Continuous intravenous hypotensive therapy is a risk factor for postoperative 24 h sICH(OR,2.278,95%CI 1.047-4.953;P=0.038),while SBPr 20%-30%is associated with a lower risk of postoperative 24 h sICH(SBPr-10%-10%as a reference,OR,0.362,95%CI0.131-0.998;P=0.049).(3)The restrictive cube plot shows that there is a U-shaped relationship between SBPr after EVT and poor clinical outcomes at 90 days,while there is a nearly linear relationship with the occurrence of sICH.The more SBP reduction,the lower the incidence of sICH.(4)In the subgroup analyses,in the non-hypertension history and the good collateral circulation group,SBPr>30%has a higher risk of poor clinical outcomes compared to SBPr-10%-10%(OR and 95%CI were 2.921[1.000-8.528]and 2.363[1.078-5.183],respectively,with P=0.05 or P<0.05);After EVT,the group receiving continuous intravenous hypotensive therapy and the baseline ASPECT score 6-10 groups showed a significant correlation between SBPr>30%and poor clinical outcomes at 90 days(SBPr-10%-10%as a reference,OR and 95%CI were 2.646[1.168-5.993]and 2.481[1.360-4.527],respectively,with P<0.05).The correlation between SBPr and lower incidence of sICH was only found in the subgroup of poor collateral circulation(SBPr-10%-10%as a reference,SBPr>20%-30%:OR,0.133,95%CI 0.027-0.652;SBPr>30%:OR,0.104,95%CI 0.013-0.864;all P<0.05).Conclusions Among patients who achieved successful reperfusion with EVT,SBPr might be related to a worse functional outcome at 90 days and sICH 24 h after operation.However,the relationship may exhibit significant heterogeneity across different subgroups.Baseline ASPECT score,history of hypertension,collateral circulation,and the use of continuous venous hypertension after EVT have been highlighted in individualized blood pressure management after EVT.

ObjectiveTo investigate the current status and development needs of evidence-based medicine (EBM) capability in ethnic minority medicine, and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions, firstly, perceptions and attitudes towards evidence-based medicine; secondly, advantages and challenges in the development of ethnic minority medicine; thirdly, demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected, of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses (70.66%) from practitioners of minority medicine, including Tibetan medicine, Mongolian medicine, Uyghur medicine, Zhuang medicine, and Korean medicine. Among the 501 questionnaires, 146 respondents (29.14%) indicated that they knew about EBM, 355 respondents (70.86%) had either a "general understanding" or had "not heard about" EBM before, and 469 respondents (93.61%) believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice (442 respondents, 88.22%). In the 9-point importance rating for enhancing evidence-based abilities, high scores were achieved in standardization of clinical practice guidelines (7.50±1.90) and methods for sample sizes in clinical research (7.45±1.90). Regarding the demand for improving clinical research literacy, expert academic lectures, and experience sharing (404 respondents, 80.64%) and evidence-based methodology monographs on ethnic minority medicine (401 respondents, 80.04%) were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However, there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM, establishing evidence-based support platforms for clinical research, organizing regular academic lectures and exchanges, and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine, thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.
