ObjectiveGastrodia elata has evolved ecological types with shortened rhizome internodes and diversified flower and fruit coloration in response to different altitudes. Studying the genetic mechanisms of different ecotype germplasm is significant for guiding variety breeding in different cultivation areas. MethodsThe bHLH gene family was identified based on the whole-genome datasets of G. elata f. elata and G. elata f. glauca. Subsequently, the gene family members were subject to analysis, including gene structure, chromosomal localization, cis-acting elements, gene synteny, and phylogeny. Combined with transcriptome data and quantitative Real-time PCR, the expression patterns of bHLH genes in the stems of the different G. elata ecotype germplasm were analyzed. Finally, correlation analysis was conducted between gene expression patterns and color to obtain the key bHLH genes regulating the color formation of stem. ResultsA total of 63 bHLH genes were identified in both G elata f. elata and G. elata f. glauca, unevenly distributed across 17 chromosomes and clustered into 16 subfamilies, with significant expansion in some family members. Obvious inversions of bHLH genes on the same chromosome and interchromosomal translocations were detected in the two ecotype germplasm. Among these genes, 12 bHLH genes (such as bHLH62-3 and bHLH74) were associated with the bright yellow color of G elata f. elata stem, while 9 bHLH genes (such as PIL13, UNE12, and bHLH130) were correlated with the red color of G. elata f. glauca stem. Compared to G. elata f. glauca, the bHLH48 expression level was significantly higher in flowers and scale leaves of G elata f. elata, and the bHLH62-3 expression level was significantly higher in all organs of G elata f. elata. ConclusionsFunctional pathway divergence of the bHLH family members has occurred across different chromosomes in G elata f. elata and G. elata f. glauca. Through synergism or antagonism with other genes, 21 bHLH genes participate in the coloration metabolic pathway regulation of stems, flowers, and fruits. Specifically, bHLH62-3 is involved in regulating stem color differentiation in the anthocyanin biosynthesis pathway of G. elata, thus relevant to the color formation of stem. Additionally, GebHLH48 positively regulates flowering-related pathways to promote the early-flowering phenotype of G. elata f. elata. These findings have laid the foundation for analyzing the genetic regulatory mechanisms underlying the color formation of the G. elata stem.

ObjectiveTo clarify the expression of TRIM28 in non-M3 acute myeloid leukemia (AML) and its correlation with clinical indicators and prognosis, and to further explore the effect of TRIM28 expression levels on the proliferation and apoptosis of AML cells using small interfering RNA. MethodsThe GSE34577 dataset was analyzed using R software to compare TRIM28 expression between healthy controls and non-M3 acute myeloid leukemia (AML) patients. Clinical samples from non-M3 AML patients were collected, with TRIM28 expression levels measured using real-time quantitative PCR (qPCR). The analysis focused on correlations between TRIM28 expression and various clinical indicators, treatment efficacy, and patient prognosis. Furthermore, small interfering RNA (siRNA) technology was employed to downregulate TRIM28 expression in human primary AML cells (HL60 cell line). The effects on cell proliferation and apoptosis were then assessed through CCK-8 assays and flow cytometry, respectively. ResultsThe results showed that TRIM28 was up-regulated in non-M3 AML of both online database GSE34577 and clinical samples (P<0.000 1), TRIM28 expression of new diagnosis group and relapsed refractory group was higher than iron deficiency anemia group (P<0.01), and there was no significance between different French-American-British classification systems subtype. TRIM28 expression was higher in non-M3 AML patients with a poor genetic prognosis stratified as moderate than in the good prognosis group, and TRIM28 expression was associated with NPM1 combined with the FLT3-ITD mutation, positively correlated with age, bone marrow blast, peripheral blood blast and white blood cell, negatively correlated with hemoglobin. In addition, interference TRIM28 greatly inhibited cell proliferation and promoted cell apoptosis. ConclusionThis study reveals that TRIM28 is highly expressed in non-M3 AML and associated with prognosis, and plays a key role in the proliferation and apoptosis of AML cells, suggesting that TRIM28 may serve as a novel therapeutic target for non-M3 AML.

Systemic lupus erythematosus (SLE), a refractory autoimmune disease, is among the dominant diseases where traditional Chinese medicine (TCM) shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46th Youth Salon on Dominant Diseases (Systemic Lupus Erythematosus)" organized by the China Association of Chinese Medicine, which led to a consensus on "the advantages, challenges, interdisciplinary approaches, and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges, such as frequent misdiagnosis and missed diagnosis in the early stages, difficulty in achieving treatment targets, multiple side effects from pharmacotherapy, and the lack of management strategies for special populations, all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema, aversion to cold and cold limbs, fatigue, dry mouth, restlessness, and heat sensation in the palms and soles, thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine, slow disease progression, reduce relapse rates, address multi-organ involvement, and prevent or treat complications. Additionally, they enhance efficacy and reduce toxicity, prevent the side effects of Western medications, help reduce hormone use, and offer distinct advantages in the individualized intervention of special populations, contributing to the whole-process management of the disease. However, evidence-based medical support for this integrated approach remains limited, and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research, strengthen the development of fundamental and pharmacological research, and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine, incorporating multi-omics technologies, individualized stratification, and other precision medicine concepts, in combination with artificial intelligence. Moreover, interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae, thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

Integrated metabolomic and lipidomic profiling,utilizing liquid chromatography coupled with high-resolution mass spectrometry(LC-HRMS),has emerged as a pivotal strategy for biomarker discovery.However,the inherent polarity disparity between metabolites and lipids complicates simultaneous analysis.To address this,a dual-stationary phase polarity-extended liquid chromatography(PELC)system was developed,which surpassed conventional one-dimensional LC(1D-LC)by enabling comprehensive coverage of both polar and non-polar compounds within a single injection.This system enhanced chromatographic resolution,peak capacity,and throughput while minimizing analytical variability.Extracellular vesicles(EVs),lipid bilayer-enclosed nanoparticles ubiquitously present in biofluids,had gained prominence as reservoirs of cancer biomarkers due to their cargo stability and pathophysiological relevance.Herein,the application of PELC-HRMS for concurrent metabolome-lipidome profiling in EVs was pioneered.A total of 193 metabolites were identified using this technique coupled with MS-DIAL software and Human Metabolome Database.Subsequently,this technique was employed to explore potential biomarkers for prostate cancer(PCa).Multivariate analysis identified 17 differentially abundant metabolites in PCa,implicating dysregulated pathways including purine metabolism,starch and sucrose metabolism,galactose metabolism,cysteine and methionine metabolism,and biosynthesis of unsaturated fatty acids.Notably,creatine(AUC=0.92)and DG 42:5(AUC=0.80)demonstrated robust diagnostic efficacy,attributable to their broad polarity ranges and EV-specific enrichment.This study established PELC as a high-fidelity platform for multi-omics integration in complex biospecimens,advancing mechanistic insights into metabolic rewiring and disease pathophysiology.

Objective:To construct a quality evaluation index system for perianal infection care in patients with hematologic neoplasms, aiming to establish a standardized approach for care.Methods:A quality evaluation index system for perianal infection management in patients with hematologic neoplasms was developed from January to June 2023 using Donabedian′s "Structure- Process- Outcome" approach, based on evidence- based literature study and expert conference discussions. An index system for evaluating the quality of perianal infection care in patients with hematologic neoplasms was established through expert consultation, and the weights for each indicator were derived using the analytic hierarchy process.Results:Two rounds of expert consultations were conducted, involving 27 experts aged 30 to 53 (38.85 ± 6.13) years, in which of them there were 1 male and 26 females. The positive coefficients of the experts in the two rounds of consultations were 100.00% (27/27) and 96.30% (26/27), respectively. The expert authority coefficients were 0.874 and 0.881, respectively, and the Kendall coordination coefficients were 0.234 and 0.219 (both P<0.05). The quality evaluation index system for perianal infection management in patients with hematologic neoplasms consisted of 3 main indicators (structural quality, process quality, outcome quality), 12 secondary indicators, and 48 tertiary indicators. Conclusions:The process of developing the quality assessment criteria for perianal infection care in patients with hematologic neoplasms is systematic and yields dependable results. The criteria cover a wide range of aspects and are specific, offering a valuable framework for assessing the quality of perianal infection care in patients with hematologic neoplasms.

Objective:To investigate the temporal correlation between occupational stress and elevated blood pressure among petroleum workers in Xinjiang.Methods:Based on the Occupational Health Study Cohort of Petroleum Workers (OHSPIW), 1600 petroleum workers in Xinjiang who underwent occupational health examinations from May to June 2015 and December 2017 were selected as the research subjects. The occupational stress of workers was evaluated using the Occupational Roles Questionnaire (ORQ) in the Occupational Stress Inventory-Revised (OSI-R). The blood pressure measurement data of physical examination results were collected. The relationship between the ORQ total score and blood pressure was analyzed using Spearman rank correlation, and the causal time-series relationship between occupational stress and elevated blood pressure over time was analyzed by cross-lagged path analysis modelling.Results:In the baseline data of petroleum workers, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 124.00 (119.00, 128.00) and 77.00 (73.00, 82.00) mmHg respectively, with an ORQ total score of 164.00 (154.00, 174.00) points. In the follow-up data, the SBP and DBP were 126.00 (123.00, 128.00) and 78.00 (75.00, 82.00) mmHg respectively, and the ORQ total score was 168.00 (157.00, 181.00) points. The results of the correlation analysis showed that the ORQ total score of petroleum workers was positively correlated with the levels of SBP and DBP ( P<0.05), and the ORQ total score at follow-up was negatively correlated with the baseline levels of SBP and DBP ( P<0.05). The results of the cross-lagged path analysis showed that the path coefficients from the baseline ORQ total score of petroleum workers to the follow-up SBP and DBP levels were statistically significant ( ρ=0.06, 0.06, P=0.032, 0.011). In terms of time sequence, the increase in the ORQ total score preceded the increase in the SBP and DBP levels. Conclusion:The occupational stress of petroleum workers is related to blood pressure, and the increase of occupational stress precedes the change of blood pressure. This correlation may increase the risk of hypertension among petroleum workers.
