ObjectiveA qualitative analysis method was established for the composition of Astragali Radix（AR） before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice（ARR）， the structures of their major compounds were deduced and identified， and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detect the samples of AR and ARR in positive and negative ion modes， respectively. The compounds were analyzed and identified through self-constructed databases， literature， and reference standards， etc. And the data were analyzed by chemometrics， in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR， including 41 flavonoids， 19 terpenoids， 26 organic acids， 8 amino acids， 5 nucleotides， 5 carbohydrates and 19 other compounds. Among them， there were 95 common components in both， 18 unique components in AR， and 10 unique components in ARR. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying， and a total of 26 constituents with differences in the content were screened out， including L-canavanine， L-pyroglutamic acid， L-phenylalanine， cis-caffeic acid， and malonylastragaloside Ⅰ. Among them， 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids， terpenoids， and organic acids， and analyzes the components with significant differences in content between the two in combination with chemometrics， and the differential components are dominated by amino acids， organic acids and terpenoids， which can provide reference for the subsequent quality control and material basis research.

Objective To calculate and analyze the research and development(R&D)efficiency,as well as the technological achievements transformation efficiency,of ten"Double First-Class"medical universities and ten medical universities in the accumulative science and technology evaluation metrics over the last five years,in order to make recommendations for improving technological achievements transformation management at these universities.Methods The study used both classic data envelopment analysis and super-effectiveness data envelopment analysis models to assess the effectiveness of the R&D stage and technological achievements transformation stage at the selected medical universities.Furthermore,the Malmquist model was used to measure the changes in the efficiency of the transformation of scientific and technological achievements of the medical universities as a whole.Results Among the 20 medical universities chosen,the output efficiency in the R&D stage was greater than that in the technological achievements transformation stage.Five medical universities were output-effective at the R&D stage,and two medical universities were in the technological achievements transformation stage.The overall efficiency of scientific and technological achievements transformation in medical universities was steadily improving.Conclusion Based on the current situation,medical universities in China should strengthen effective collaboration between industry,academia,and research,establish professional teams for technological achievements transformation,improve the technological achievements transformation management system,improve talent team construction,and increase technological achievements transformation efficiency.

Sepsis is a common critical illness in clinical practice,characterized by rapid progression and high mortality.Its complex pathogenesis remains a major focus and challenge in the field of critical care medicine.Disseminated intravascular coagulation(DIC)is one of the most frequent and severe complications of sepsis,featuring systemic activation of the coagulation cascade and microthrombus formation,significantly increasing the mortality.Coagulation factorⅫ(FⅫ),a serine protease,is considered to have therapeutic potential for thrombosis without impairing normal hemostasis.Study reveal that neutrophil extracellular trap(NET),web-like DNA structures released through a unique process known as NETosis,provide negatively charged scaffolds that promote FⅫ binding and activation,thus triggering the intrinsic coagulation cascade and contributing to a hypercoagulable state.In recent years,increasing attention has been paid to the interaction between NET and FⅫ in sepsis complicated with DIC.These 2 factors play central roles in intravascular thrombus formation and coagulation activation.Beyond their antimicrobial function,NET can aggravate tissue injury and coagulation abnormalities by releasing proinflammatory mediators such as myeloperoxidase(MPO),neutrophil elastase(NE),and reactive oxygen species(ROS).FⅫ activation can further trigger the kallikrein-kinin system(KKS)and activate FⅪ,amplifying inflammation and thrombosis in a vicious cycle.Traditional Chinese medicine(TCM),as a key component of Chinese medical heritage,has demonstrated unique advantages in managing sepsis and its complications.Based on therapeutic principles such as"strengthening healthy qi and eliminating pathogenic factors"and"tonifying qi and activating blood circulation",TCM is believed to regulate immune function and correct coagulation disorders,thereby interfering with the hypercoagulable state mediated by NET and FⅫ,slowing the progression of DIC,and improving clinical outcomes.Several herbs,including Salvia miltiorrhiza,Astragalus membranaceus,Rheum officinale,Ligusticum chuanxiong,and Curcuma longa,have shown anticoagulant,antiplatelet,and anti-inflammatory properties.In addition,compound formulations such as Xuebijing injection and Qingwen Baidu decoction have demonstrated clinical efficacy in improving coagulation parameters,reducing D-dimer levels,and protecting organ function.Although current evidence on the effects of TCM on NET formation and FⅫactivation is still limited,its potential mechanisms and clinical value warrant further investigation.This review summarizes the critical roles and interplay of FⅫand NET in sepsis complicated with DIC and discusses the advances in TCM-based interventions,aiming to provide new perspectives for mechanism-oriented research and integrative therapeutic strategies.

Oral submucous fibrosis (OSF), characterized by excessive deposition of extracellular matrix (ECM) that causes oral mucosal tissue sclerosis, and even cancer transformation, is a chronic, progressive fibrosis disease. However, despite some advancements in recent years, no targeted antifibrotic strategies for OSF have been approved; likely because the complicated mechanisms that initiate and drive fibrosis remain to be determined. In this review, we briefly introduce the epidemiology and etiology of OSF. Then, we highlight how cell-intrinsic changes in significant structural cells can drive fibrotic response by regulating biological behaviors, secretion function, and activation of ECM-producing myofibroblasts. In addition, we also discuss the role of innate and adaptive immune cells and how they contribute to the pathogenesis of OSF. Finally, we summarize strategies to interrupt key mechanisms that cause OSF, including modulation of the ECM, inhibition of inflammation, improvement of vascular disturbance. This review will provide potential routes for developing novel anti-OSF therapeutics.

OBJECTIVE This study aims to investigate the epidemiological characteristics and influencing factors of skin diseases among soldiers performing duties and working in tunnel environments,and to propose targeted pre-ventive and therapeutic measures.METHODS A cross-sectional survey was conducted on 537 soldiers from multi-ple sites within a military unit from Nov.2022 to Oct.2023.The survey collected data on general information,liv-ing habits,and details of current skin diseases,including types,symptoms,duration and treatment status.Logis-tic regression analysis was applied to identify risk factors for the skin diseases observed.RESULTS A total of 21 types of skin diseases were identified,with dermatophyte infections being the most prevalent(59.96％,322/537),followed by acne(26.82％,144/537).Further analysis revealed that the incidence of dermatophyte infec-tions was closely associated with the region where the soldiers were stationed[OR(95％CI)=1.694(1.062,2.693),P=0.032]and the frequency of sock washing[OR(95％CI)=1.734(1.023,2.988),P=0.043],but no significant correlation was found between the prevalence of dermatophyte infections and the frequency of washing feet[OR(95％CI)=1.520(0.836,2.824),P=0.175].CONCLUSIONS This study highlights the epidemiological char-acteristics and key risk factors for skin diseases among soldiers in tunnel environments.Targeted prevention strategies are proposed,providing valuable scientific evidence for the prevention and control of skin diseases in similar environments.

Objective To evaluate the clinical efficacy of hip-knee-ankle active and passive exercise therapy in patients with early-to mid-stage knee osteoarthritis(KOA).Methods A total of 180 patients with early to mid-stage knee osteoarthritis(KOA)were recruited from the First Affiliated Hospital of Hebei University of Tradi-tional Chinese Medicine between March 2023 and March 2024.Patients were randomly assigned to one of four groups:active movement group,passive movement group,combined movement group,and control group,with 45 patients in each group.The active movement group received hip-knee-ankle active movement therapy daily until the end of follow-up.The passive movement group underwent hip-knee-ankle passive movement therapy three times per week for two weeks.The combined movement group received both active and passive therapies.The control group was administered oral celecoxib capsules(200 mg once daily for two weeks).Joint function was assessed in all four groups before treatment,at two weeks post-treatment,and at 14 weeks post-treatment.The primary outcome measure was the WOMAC joint function score,while secondary outcomes included the WOMAC pain score,stiffness score,and quality of life score(SF-12).Results A total of 160 patients completed the trial,with 39 in the active group,42 in the passive group,40 in the combined group,and 39 in the control group.There were no significant differences in baseline characteristics among the groups(P>0.05).Compared to baseline,the WOMAC scores for function,pain,and stiffness in the passive,combined,and control groups decreased significantly at both 2 and 14 weeks post-treatment(P<0.05),while the SF-12 scores increased significantly(P<0.05).Between 2 and 14 weeks post-treat-ment,the active and combined groups showed further significant decreases in WOMAC function,pain,and stiffness scores(P<0.05)and increases in SF-12 scores(P<0.05).At 2 weeks post-treatment,compared to the control group,the passive and combined groups exhibited significantly lower WOMAC function scores(P<0.05),with no significant difference between the passive and combined groups(P>0.05).By 14 weeks post-treatment,the active and combined groups demonstrated significantly lower WOMAC function scores(P<0.05),with the combined group showing a significantly lower score than the active group(P<0.05).Conclusion The four therapeutic approaches demonstrate a certain degree of efficacy in improving joint function for patients with early and mid-stage KOA.The passive therapy group exhibits superior short-term outcomes,while the active therapy group shows better long-term benefits.The combined therapy group presents notable advantages in both short-term and long-term effi-cacy,although its short-term effectiveness does not surpass that of the passive therapy group.It is recommended for patients with early and mid-stage KOA who have underlying gastrointestinal and cardiovascular conditions.
