According to the Qi-blood-body fluid theory and the association between the spleen in visceral manifestation theory of traditional Chinese medicine （TCM） and mitochondria in modern cellular biology， it is proposed that the role of the spleen in generating and transforming Qi and blood is analogous to the energy-producing function of mitochondria—both serving as fundamental power sources for vital activities of the human body. The spleen governs transportation and transformation， playing a critical role in energy metabolism and the digestion and absorption of nutrients. Similarly， mitochondria are vital for maintaining physiological functions such as cellular energy supply， cell survival， and overall human metabolism. Furthermore， spleen deficiency is closely linked to mitochondrial dysfunction. Accordingly， mitochondrial energy conversion and substance metabolism are regarded as the microscopic essence of the spleen's function in transportation and transformation. Spleen deficiency and mitochondrial dysfunction contribute to the formation of pathological products such as phlegm-turbidity and blood stasis. This aligns with the pathogenesis of chronic obstructive pulmonary disease （COPD）， with Qi deficiency as the root cause and phlegm-turbidity and blood stasis as the manifestations. Therefore， the integrative treatment of COPD should follow the therapeutic principle of invigorating the spleen and reinforcing healthy Qi， while also resolving phlegm and removing blood stasis to address both root cause and manifestations. This approach can improve the mitochondrial function， regulate energy metabolism， and reduce oxidative stress levels to alleviate COPD symptoms， slow down disease progression， and improve prognosis. By integrating the holistic concept of TCM with molecular mechanisms of modern medicine， this paper explores the pathogenesis and therapeutic principles of COPD from the spleen-mitochondria correlation. It not only provides a new direction for the modern development of TCM and the integration of Chinese and Western medicine but also offers a theoretical foundation for the integrated treatment of chronic， complex age-related diseases.

Objective To determine the molecular mechanism of Yuchang granule (YCG) against ulcerative colitis （UC） by network pharmacology-based approach combined with molecular docking. Methods TCMSP and HIT database were utilized to search the active components and potential targets of YCG. The effective targets of UC were obtained by GeneCards, CTD, and DisGeNET databases. Venn Diagram was exploited to receive common targets of YCG and UC. Network maps of the TCM of YCG-active component-common targets were constructed by the Cytoscape software to gain key active components. Protein-protein interaction （PPI） of common targets was constructed by the STRING database obtaining core common targets. The mechanism and therapeutic effects of YCG on UC were explored via gene ontology （GO） and the biological pathway （KEGG） enrichment analyses. Molecular docking technology was carried out to verify the combination of core active components with key common targets. Results 98 active components and 237 potential targets were sieved from YCG, and 1061 effective targets were screened from UC. 94 common targets of YCG and UC were regarded as potential therapeutic targets. Bioinformatics analysis revealed that quercetin, luteolin, β-quebrachol, stigmasterol, and kaempferol may be the potential candidate agents. Tumor necrosis factor （TNF）, serine/threonine-protein kinase （AKT1）, tumor protein p53 （TP53）, interleukin-6 （IL-6） and IL-1β could become potential therapeutic targets. KEGG showed pathways in cancer, AGE-RAGE signaling pathway in diabetic complications, TNF signaling pathway, and IL-17 signaling pathway might play an important role in YCG against UC. Molecular docking results showed that quercetin combined well with TNF, AKT1, and TP53. And stigmasterol did well with AKT1. Conclusion This study comprehensively illustrated the potential candidate agents, potential therapeutic targets, and pathways of YCG against UC. It also illustrated that YCG could act on multiple targets through multi-pathway treating UC.

Objective: To establish a rapid, accurate, and decentralized workflow for bacterial whole-genome sequencing (WGS) and risk profiling within the shelf-life of platelet concentrates, and to characterize the species, virulence, antimicrobial resistance (AMR), and immune evasion mechanisms of co-existing bacteria in qualified platelet products, thereby providing a scientific basis for transfusion safety assessment. Methods: Three units of platelet concentrates, which tested negative by routine bacterial screening, were collected from the Chengdu Blood Center between May and June 2025. Samples were enriched at 37℃under six aerobic and nine anaerobic conditions for 7 days. Using a culturomics strategy, aliquots were plated for isolation on days 1, 3, 5, and 7 to obtain cultivable isolates, with negative culture controls included to exclude contamination. High-molecular-weight genomic DNA was extracted via mechanical grinding, purified, and size-selected. Sequencing libraries were constructed and sequenced on the G-seq500 single-molecule nanopore sequencing platform. Genomes were assembled using Flye and polished with NextPolish, with quality evaluated by BUSCO and CheckM. Taxonomic identification was performed using GTDB-Tk. Functional annotation and database comparisons were conducted to analyze virulence factors, AMR genes, and genes related to immune evasion and environmental adaptation. Results: Viable bacteria were successfully isolated from all three qualified platelet units within their shelf life. The isolates were identified as Bacillus albus, Niallia taxi, and Staphylococcus warneri. Nanopore sequencing generated 92 227-109 813 reads (totaling 680-758 Mb) with an N50 of 7 625-8 584 bp and Q20/Q30 scores of 97%/93%, respectively. All three genomes were assembled into complete circular chromosomes with 1-3 plasmids, achieving >93% completeness. Functional analysis revealed that B. albus carried multiple hemolysins, metalloproteases, and multidrug resistance genes, indicating the highest potential pathogenicity and AMR risk. S. warneri exhibited a typical multidrug resistance profile and regulatory network characteristic of coagulase-negative staphylococci, suggesting intermediate virulence. N. taxi harbored few canonical virulence factors and lacked functional AMR determinants, presenting a "low-virulence, low-resistance" profile. Notably, all three strains were enriched in genes encoding antimicrobial peptide resistance systems (e.g., dltABCD, mprF, GraRS, BceAB) and antioxidant enzymes, suggesting a strong capacity to withstand immune stress in the blood environment. Conclusion: Viable bacteria can be recovered from qualified platelet concentrates that test negative by routine screening. Nanopore WGS enables rapid strain-level identification and comprehensive risk profiling of virulence, resistance, and immune adaptation traits. The functional repertoires of these "co-existing" isolates range from environmental adaptation to potential pathogenicity, representing an underappreciated risk for transfusion-transmitted infections in susceptible recipients.

ObjectiveThis study aims to investigate the effect of Liuwei Dihuangwan on the autophagy function in the hippocampus of senescence-accelerated mouse prone 8 （SAMP8） by regulating the expression of glycoprotein non-metastatic melanoma protein B （GPNMB）. Furthermore， it is designed to explore the mechanism of the method of tonifying the kidneys and replenishing essence in the treatment of Alzheimer's disease （AD）. MethodsIn experiment 1， 24 5-month-old SAMP8 mice were randomly and equally divided into the model group， and the low-， middle- and high-dose（0.59，1.18，2.36 g·kg^-1） Liuwei Dihuangwan groups. At the same time， six 5-month-old senescence accelerated mouse resistant 1 （SAMR1） mice were used as the control group. The learning and memory ability was evaluated through novel object recognition experiment. Serum cortisol （Cort）， adrenocorticotropic hormone （ACTH） and urine 17-hydroxycorticosteroid （17-OHCS） levels were detected by enzyme-linked immunosorbent assay （ELISA）. The ultrastructure of hippocampal neurons was observed by transmission electron microscope （TEM）， and the expression levels of hippocampal GPNMB， a disintegrin and metalloproteinase 10 （ADAM10） and autophagy-related proteins were detected by Western blot. In experiment 2， 18 SAMP8 mice were randomly and equally divided into the model group， vector control group （Vector）， and GPNMB overexpression group （GPNMB^OE）. Lentiviral vectors were stereotactically injected into the brain （2 μL per side in the GPNMB^OE group）. Western blot was used to detect the expression of the above target proteins in the hippocampus； In Experiment 3， 24 SAMP8 mice were randomly and equally divided into the model group， Liuwei Dihuangwan group， Liuwei Dihuangwan+negative control （NC） group， and Liuwei Dihuangwan+GPNMB silencing group （shGPNMB）. Before drug treatment， the Liuwei Dihuangwan+NC group and the Liuwei Dihuangwan+shGPNMB group were injected with negative control and GPNMB silencing lentivirus， respectively. Western blot was used to detect the expression of the above target proteins in the hippocampus. ResultsThe novel object discrimination index of mice in the model group was significantly lower than that of mice in the control group （P<0.01）. The novel object discrimination index of mice in the medium- and high-dose Liuwei Dihuangwan groups was significantly higher than that of mice in the model group （P<0.01）. Aggregated autolysosomes were observed in the normal hippocampus tissue by TEM. In the model group， mitochondria were dominant， and no typical characteristic autophagosomes were observed. In the low- and medium-dose Liuwei Dihuangwan groups， a small number of autolysosomes and autophagosomes with double-membrane structures were observed. In the high-dose Liuwei Dihuangwan group， the number of autophagosomes and autolysosomes was greater than that in the low- and medium-dose groups. The results of ELISA and Western blot showed that compared with the control group， the levels of serum Cort， ACTH， and urine 17-OHCS in the model group were substantially increased， while the expression of hippocampal ADAM10， Beclin1， and microtubule associated-protein light chain 3-Ⅱ/Ⅰ （LC3 Ⅱ/Ⅰ） was significantly decreased. The expression of GPNMB and ubiquitin binding protein p62 was significantly increased （P<0.05， P<0.01）. Compared with the model group， the serum Cort and ACTH levels in the low-， medium-， and high-dose Liuwei Dihuangwan groups were significantly reduced， while only the urine 17-OHCS level in the high-dose group was significantly reduced. The hippocampal GPNMB， ADAM10， Beclin1， and LC3 Ⅱ/Ⅰ expression levels in the medium-， and high-dose groups of Liuwei Dihuangwan were significantly increased compared to the model group， whereas the expression of p62 was significantly reduced （P<0.01）. The above indicators showed a progressive trend among the three groups. Compared with the model group， the GPNMB^OE group showed a significant increase in GPNMB， ADAM10， Beclin1， LC3 Ⅱ/Ⅰ expression， and a significant decrease in p62 expression （P<0.01）. Compared with the model group， the expression of GPNMB， ADAM10， Beclin1， and LC3 Ⅱ/Ⅰ in the hippocampus of the Liuwei Dihuangwan group significantly increased， while the expression of p62 significantly decreased （P<0.01）. Compared with the Liuwei Dihuangwan group， the Liuwei Dihuangwan+shGPNMB group showed a significant decrease in GPNMB， ADAM10， Beclin1， LC3 Ⅱ/Ⅰ， and a significant increase in p62 expression （P<0.01）. ConclusionLiuwei Dihuangwan can enhance hippocampal autophagy function and improve AD by upregulating GPNMB expression.

Conclusion Elderly patients usually suffered from a variety of diseases and required multiple drugs. The application of therapeutic regimen for elderly patients with Hp should be supposed to fully weigh the risks and benefits.

PURPOSE: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. METHODS: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. RESULTS: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. CONCLUSION More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

OBJECTIVE: To analyze the gene mutation characteristics and survival time of patients with newly diagnosed acute myeloid leukemia (AML) based on next-generation sequencing(NGS) gene detection. METHODS: A retrospective analysis was conducted on the clinical data of 92 patients with AML (non APL) admitted to our hospital from January 2018 to May 2022. AML related genes tested were using NGS, the mutation characteristics and survival time of AML patients were analyzed. RESULTS: Among the 92 patients, 41 were males and 51 were females. A total of 38 types of gene mutations were detected. Six-two patients carried at least one gere mutation, while no gene mutations were detected in 30 patients. In the group with favourable prognosis (n =14), the frequencies of higher gene mutations were NRAS, KIT (21.43%, n =3), KRAS (14.29%, n =2). In the group with intermediate prognosis (n =64), the gene mutation frequencies from high to low were DNMT3A (18.75%, n =12), NPM1 (17.19%, n =11), IDH2, FLT3-ITD, CEBPA (12.50%, n =8), TET2 (10.94%, n =7). In the poor prognosis group (n =14), ASXL1, TP53, EZH2, NRAS had higher gene mutation frequency than others(14.29 %, n =2 ). Statistical analysis revealed that KIT had a relative hotspot of mutations in the intermediate-risk group, and DNMT3A had a relative hotspot of mutations in the high-risk group (P < 0.05). The correlation analysis of genes with high mutation rates in different prognostic groups, such as NRAS, KIT, IDH2, DNMT3A, NPM1, and FLT3-ITD, with prognosis found that KIT was a factor affecting OS (P < 0.05), while no significant differences were observed for the others(P >0.05). CONCLUSION The frequency of gene mutations is high in AML patients, 67.4% of the patients carried at least one gene mutation. The mutation frequency varies among different genes in patients with different karyotypes, and there are obvious dominant mutations. KIT and DNMT3A can be used as factors for evaluating the prognosis of AML.
