Lung cancer is the leading cause of cancer-related deaths worldwide， and tumor metastasis is a key factor contributing to the mortality of most lung cancer patients. Aberrant activation of epithelial-mesenchymal transition （EMT） is a major driver of lung cancer progression and metastasis. EMT is characterized by the loss of apical-basal polarity and intercellular adhesion in highly differentiated， polarized， and organized epithelial cells， which acquire motility， migratory potential， and invasive properties. During this process， cells undergo cytoskeletal remodeling and transform into a mesenchymal phenotype， accompanied by associated changes in cellular markers. The EMT process is highly complex and is tightly regulated by intricate networks involving multiple transcription factors， post-translational controls， epigenetic modifications， and non-coding RNAs. Therefore， therapies targeting the mechanisms of malignant transformation and their associated pathways in lung cancer are of significant clinical importance. In recent years， EMT has attracted increasing attention as a potential target for cancer therapy. Chinese medicine， with its characteristics of multi-target action， low side effects， and good therapeutic efficacy， has demonstrated an important role in anticancer treatment. A series of studies have investigated the role of Chinese medicine in inhibiting EMT in lung cancer. Active ingredients of Chinese medicine， including flavonoids， glycosides， phenols， terpenoids， saccharides， and alkaloids， as well as Chinese medicine compound formulas， have shown significant regulatory effects on EMT. Their mechanisms mainly involve multiple pathways， targets， and links， including signaling pathways， exosomes， microRNAs （miRNAs）， and the tumor-associated immune microenvironment. This article summarizes the mechanisms by which EMT promotes malignant tumor progression and reviews the current research on how Chinese medicine active ingredients， monomers， and compound formulas inhibit EMT and suppress lung cancer cell migration and invasion. This study is expected to provide comprehensive theoretical information for basic and translational research on lung cancer.

Objective To investigate whether microRNA-21-5p(miR-21)plays a protective role in hyperoxia-induced acute lung injury(HALI)by regulating ferroptosis through the STAT3/P53/SLC7A11 axis.Methods The interaction between STAT3 and P53 was analyzed by co-immunoprecipitation(Co-IP).Fifty 9-week-old male C57BL/6J mice were randomly divided into normoxia(Control)group,HALI group,miR-21 overexpression(miR-21)group,STAT3 inhibitor(HY-13818)group,and ferrostatin-1(Fer-1)group.After the mice from the miR-21 group received miR-21-5p AAV6 or empty vector via tracheal catheter instillation,the animals were then monitored for 3 weeks.The HY-13818 group was intraperitoneally injected with HY-13818(10 mg/kg)3 times weekly for 2 weeks.The Fer-1 group received 0.8 mg/kg ferrostatin-1 via tail vein injection once daily for 2 consecutive days during modeling.The HALI model was established by exposure to>90%oxygen.After 48 h of hyperoxia,blood samples were collected via orbital sampling for RT-PCR analysis of miR-21 expression.Lung tissues were harvested for wet/dry weight ratio and assessment of histopathological changes via HE staining for lung injury score.Activity of superoxide dismutase(SOD)and contents of malondialdehyde(MDA),Fe2?,glutathione(GSH),and reactive oxygen species(ROS)were measured using photocolorimetry,spectrophotometry and fluorometry.Western blotting was used to evaluate the protein expression of STAT3,P53,SLC7A11,and GPX4.Results The results of Co-IP showed that STAT3 could bind to P53.The HALI group exhibited obviously destroyed alveolar structure,disordered arrangement,thickened interval,with a large number of infiltrated neutrophils and collapsed alveoli,and had significantly increased pathological score of lung injury and ratio of lung Wwet/Ddry weight when compared with the Control group(P<0.05).In the miR-21 group,HY-13818 group and Fer-1 group,the severity of lung injury was significantly reduced,and the pathological score of lung injury and the ratio of Wwet/Ddry weight were decreased(P<0.05)when compared with the HALI group.Compared with the control group,the contents of MDA,Fe2+and ROS were increased(P<0.05),the activity of SOD and content of GSH were declined(P<0.05),the protein levels of STAT3 and P53 were increased(P<0.05),and those of SLC7A11 and GPX4 were decreased(P<0.05)in the HALI group.Compared with the HALI group,decreased MDA and ROS levels(P<0.05),enhanced SOD activity,Fe2+and GSH levels(P<0.05),down-regulation of STAT3 and P53(P<0.05)and up-regulation of SLC7A11 and GPX4(P<0.05)were observed in the miR-21 group and HY-13818 group.Conclusion MiR-21 alleviates HALI,which may be related to its inhibition of ferroptosis through the STAT3/P53/SLC7A11 axis.

Objective:To observe any effect of dynamic instability training on the balance and posture control of persons with chronic ankle instability (CAI).Methods:Thirty persons with CAI were divided at random into a control group and an observation group, each of 15. Both groups received routine rehabilitation interventions (including ankle strength training, kinesio taping, and vibration training), while the observation group additionally underwent 20 minutes of dynamic instability training daily, 5 days a week for 4 consecutive weeks. Before and after the treatment, everyone′s balance was evaluated using the Berg balance scale (BBS) and the star moving balance test (SEBT). Surface electromyography (sEMG) was used to collect electromyograms of the affected peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles of both groups within 100ms before and after landing in the jump-landing test. The intensity of muscle activation was thus analyzed.Results:After the treatment there was significant improvement in the average BBS scores, anterior medial SEBT, medial SEBT and posterior medial SEBT results of both groups. On average, all three SEBT results [(80.27±4.06)cm, (90.27±4.06)cm and (97.73±3.47)cm respectively] were significantly better in the observation group than in the control group. The standardized integrated electromyographs of the peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles on the affected sides showed significant improvement compared with before the treatment, but there too the observation group′s results were significantly better than those of the control group.Conclusions:Combining dynamic instability training with conventional rehabilitation can further improve the balance and postural control of persons with chronic ankle instability.

Background: s/Aims: Anti-mitochondrial M2 antibody (AMA-M2) is a specific marker for primary biliary cholangitis (PBC) and it could be also present in non-PBC individuals. Methods: A total of 72,173 Chinese health check-up individuals tested AMA-M2, of which non-PBC AMA-M2 positive individuals were performed follow-up. Baseline data of both clinical characteristics and laboratory examinations were collected in all AMA-M2-positive individuals. Least absolute shrinkage and selection operator (LASSO) regression was performed to investigate the potential variables for developing PBC. Results: A total of 2,333 individuals were positive with AMA-M2. Eighty-two individuals had a medical history of PBC or fulfilled the diagnostic criteria of PBC at baseline, and 2,076 individuals were non-PBC. After a median follow-up of 6.6 years, 0.6% developed PBC, with an accumulative 5-year incidence rate of 0.5%. LASSO regression showed that levels of alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), immunoglobulin M (IgM), eosinophilia proportion (EOS%), gamma globulin percentage, and hemoglobin (HGB) were potential variables for developing PBC. Multivariate Cox regression is used to construct a predictive model based on 7 selected variables, and time-dependent receiver operating characteristic analysis showed that the area under the curve of the prediction model at 3, 5, and 10 years were, respectively, 1.000, 0.875, and 0.917. Conclusions This study offers insights into the onset of PBC among individuals who tested positive for AMA-M2 during routine health check-ups. The prediction model based on ALP, GGT, IgM, EOS%, gamma globulin percentage, HGB, and sex has a certain predictive ability for the occurrence of PBC in this population.

Fusarium head blight (FHB), caused by Fusarium graminearum, not only leads to severe yield losses but also poses a threat to food safety due to the mycotoxins produced by the pathogen. Since this disease is preventable but not curable, the current control mainly relies on chemical fungicides, the long-term use of which may lead to pathogen resistance and environmental pollution. To develop green control methods, we screened 13 biocontrol strains from the rhizosphere soil of wheat, among which strain No. 12 (identified as Pythium aphanidermatum) showed significant antifungal effects. In the plate confrontation test, this strain reduced the colony diameter of the pathogen by 69.2% (1.47 mm vs. 4.78 mm in the control group), with an inhibition rate of 77% (P < 0.01). Microscopic observation revealed obvious deformations in the pathogen hyphae, suggesting a lysing effect. The coleoptile experiment further confirmed that the pre-treatment with this strain reduced the incidence rate to 0. These findings provide new candidate strains for the biocontrol of FHB and offer a scientific basis for reducing the use of chemical fungicides and promoting sustainable agricultural development.

Based on the Delphi method, this study conducted an expert questionnaire survey on the diagnostic criteria of edema in TCM by integrating preliminary literature research, aiming to further standardize the revision of Edema diagnosis in Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine (ZY/T001.1－94). Relevant literature on TCM edema was comprehensively retrieved from CNKI, Wanfang Data, VIP and CBM from 1994 to July 1, 2021. The content extracted from the literature was integrated with the diagnostic criteria outlined in the 1994 Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine to establish the questionnaire item pool; two rounds of Delphi expert surveys were conducted to identify content requiring revisions. Subsequently, the degree of concentration and coordination of the expert opinions were analyzed to determine items for inclusion in the revised draft. Ultimately, the finalized revised diagnostic criteria for edema were developed through expert panel discussions. Results showed expert participation rates of 84.21% and 78.13% in respective survey rounds. The progressive increase in Kendall's coefficient of concordance (Kendall's W=0.169 in Round 1 to Kendall's W=0.368 in Round 2) quantitatively validated enhanced expert consensus (both the degree of concentration and coordination) and systematic alignment of revision proposals for diagnostic items. The study findings demonstrated an urgent need for improving the diagnostic criteria section of the the 1994 Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine, and the proposed revisions would be expected to enhance the applicability and specificity of edema diagnostic standards in clinical practice.

A 20-year-old male patient with T-lymphoblastic lymphoma/leukemia received 9/10 human leukocyte antigen-compatible unrelated peripheral blood stem cell transplantation. He was transplanted with 5.91×10 8 mononuclear cells/kg and 2.88×10 6 CD34 + cells/kg, and neutrophil engraftment was obtained at +11 days and platelet engraftment at +9 days. After transplantation, he presented with repeatedly increased serum creatinine levels, BK virus (BKV) -associated hemorrhagic cystitis, and BKV viremia. BK virus nephropathy was diagnosed based on renal biopsy and metagenomic next-generation sequencing. After adjusting the immunosuppressant, intravenous immunoglobulin, and donor lymphocyte infusion treatment, the patient’s renal function deteriorated progressively, and he eventually died of multiple organ failure at +289 days.

Objective To analyze the global burden of disease and cross-national imbalances of tracheal,bronchial and lung cancer from 1990-2021 and to further predict changes up to 2040.Methods Age-standardised incidence rate(ASIR),prevalence rate(ASPR),mortality rate(ASMR),disability-adjusted life years rate(ASDR)and 95%confidence interval(95%UI)were extracted from GHDx.The official data platform of the institute for health metrics and evaluation(IHME)and the source of data were the Global Burden of Disease Study 2021(GBD 2021)for global burden of disease of trachea,bronchus and lung cancer.The estimated annual percentage change(EAPC)was calculated to describe the prevalence at global,regional and national levels,to understand the differences in diseases at different gender,age and socio-demographic index(SDI)levels,and to explore the overall situation through cluster analysis,cross-country health inequality analysis and to predict the future prevalence up to 2040 through Nordpred model.Results Globally,the ASIR for tracheal,bronchial and lung cancer fluctuated slightly from 1990 to 2009,and began to decline rapidly after 2009,with an ASIR of 26.42/100 000 in 2021.ASPR showed an increasing and then decreasing trend,reaching a peak in 2011,with a peak of 37.28/100 000 in 2021,while the ASMR and the ASDR showed a general decreasing trend.Tracheal,bronchial and lung cancer diseases showed the highest disease burden in men,those aged 65-74 and in countries and regions with high SDI.ASDR burden showed significant inequalities globally,with a significant positive correlation between ASDR and SDI,mainly concentrated in countries and regions with high SDI,and the unequal burden of ASDR for tracheal,bronchial and lung cancer decreases over time.Predictive analyses found that the number of new cases,current cases,deaths and disability-adjusted life years(DALY)for tracheal,bronchial and lung cancer were expected to increase through 2040,whereas ASIR,ASPR,ASMR and ASDR were projected to decrease each year.Conclusion The overall burden of tracheal,bronchial and lung cancer has declined globally from 1990 to 2021,but with demographic and regional differences.The actual number of cases will continue to climb in the future,despite the continuing decline in age-specified rates,and disease prevention and control will need to focus on growth trends and equity in resource allocation.
