ObjectiveTo investigate the effect of Huangqi jiuni decoction （HQJND） on acute liver injury in severely scalded rats and its possible molecular mechanism by animal experiments and modern pharmacological tools. MethodsFirstly， the rat model of sepsis was established and randomly divided into 4 groups. The normal saline group was given 1 mL of normal saline twice a day， and the traditional Chinese medicine group was given 1 mL of concentrated huangqi jiuni decoction twice a day. After 72 hours of shock， the samples were sacrificed， and then the serum liver function and （+）-haematoxylin eosin staining were performed to verify the efficacy of the drug. Sham Operation Group and sepsis group were fed normally without any special treatment. Then， network pharmacology was used to screen the targets of drugs and drug responses and predict the signaling pathways that might play a role in the treatment of diseases. Finally， fluorescence quantitative PCR （RT-qPCR） was performed to detect gene expression， Western blot （WB） was performed to detect tumor necrosis factor （TNF-α）， P65， phosphorylated P65 （P-P65）， and immunohistochemical （IHC） were performed assays to verify drug efficacy and explore the mechanism of drug treatment. ResultsSerum liver function and histopathology in rats showed that HQJND significantly improved liver function in severely burned rats. Network pharmacology screening was used to identify 353 disease-related marker genes and 286 drug targets. It was predicted that tumor necrosis/NF-NF-κB pathway （TNF/NF-NF-κB pathway） might be a key pathway for HQJND to treat acute liver injury after severe burns. The results of immunohistochemistry （IHC） showed that the staining of TNF-α in the liver of the sepsis group was more than that of the sham operation group and the traditional Chinese medicine group. The results of RT-qPCR and WB showed that the expression of TNF-α， TNFR1 and P65 proteins in the liver of rats in the sepsis group was significantly higher than that in the sham operation group and the traditional Chinese medicine group； on the contrary， the expression of TNF-α， TNFR1 and P65 proteins in the liver of rats in the sepsis group was significantly higher than that in the sham operation group and the traditional Chinese medicine group. The expression level of nuclear factor-kappa B（IκBα） was higher in the sham operation group and the traditional Chinese medicine group， indicating that drug treatment effectively inhibited the activation of the TNF/NF-κb signaling pathway. ConclusionAnimal experiments and network pharmacology results confirm that HQJND has a protective effect on acute liver injury in severely burned rats， which may be related to the inhibition of TNF/NF-κB signaling pathway.

OBJECTIVE To construct a preoperative medication reconciliation model assisted by a localized large language model （LLM） for gastric cancer and evaluate its clinical efficacy. METHODS A total of 249 gastric cancer patients with a history of continuous medication before admission in the Gastric Surgery Department of Jiangsu Cancer Hospital were retrospectively enrolled. Patients were divided into training set （154 cases） and validation set （95 cases） based on the order of time. Based on guidelines， drug package inserts， and other evidence， a standardized medication reconcili ation process and a structured knowledge base were constructed. DeepSeek-V3 LLM was deployed privately in the hospital， combined with retrieval-augmented generation technology， to achieve automated integration of medication information， risk screening， and generation of personalized recommendations. The quality of LLM-generated recommendations was evaluated using automatic metrics （BERT Score and ROUGE-1， 2， L） and manual scoring [seven-dimensional index （7DI） ] . Spearman correlation analysis was performed to explore the correlation between automatic scores and manual scores. Cronbach’s α coefficient was used to test the internal consistency of manual scoring results. The time consumed by manual and LLM-assisted medication reconciliation was compared across tasks of different difficulty levels （simple， moderate， and high）. RESULTS A structured knowledge base covering 8 major drug categories was finally established， covering common and high-risk preoperative medication scenarios and providing structured retrieval support for the LLM. For automatic evaluation， the precision， recall， and F1-score of BERT Score were 0.783±0.033， 0.811±0.038， and 0.796±0.028， respectively. The F1-scores of ROUGE-1， ROUGE-2 and ROUGE-L were 0.566±0.067， 0.338±0.076 and 0.468±0.082， respectively. The 7DI scores from three manual raters ranged from 32.06 to 33.45. The F1-score of automatic scoring was significantly positively correlated with the 7DI score of manual scoring （maximum coefficient of determination＝0.611， P ＜0.001）， and the internal consistency of manual scoring was good （Cronbach’s α ＝ 0.876）. In terms of efficiency， LLM-assisted medication reconciliation reduced time consumption by more than 90% compared with manual reconciliation in the simple， moderate， and high-difficulty groups （ P ＜0.001）. CONCLUSIONS The medication reconciliation model constructed based on a localized LLM and structured knowledge base shows high accuracy， consistency， and clinical applicability in complex preoperative medication scenarios for gastric cancer. It can improve the efficiency of medication reconciliation and reduce potential medication risks.

Background/Aims: Natural killer (NK) cell function is generally considered dampened in chronic hepatitis B virus (HBV) infection; however, the NK cell pool exhibits phenotypic and functional heterogeneity, and the antibody--mediated effect of NK cells remains less characterized. This study evaluated the dynamic changes in antibody-mediated NK cell responses and the involvement of distinct NK subsets across disease stages and during antiviral treatment. Methods: A T-cell receptor-like antibody specific for the HBV core 18–27 peptide (cTCRL-Ab) was used to determine the antibody-mediated effect of NK cells, and an array of NK cell surface markers were analyzed in cross-sectional and longitudinal cohorts of patients with chronic HBV infection. Single-cell RNA sequencing (scRNA-seq) was performed to identify the heterogeneity of NK subsets. Results: The cTCRL-Ab enabled the detection of NK cell cytolytic activity and IFNγ production. Notably, cTCRL-Ab-mediated NK cell responses were compromised in chronically HBV-infected patients, particularly in those receiving pegylated interferon-α (Peg-IFNα), which was associated with the downregulation of CD16 expression. Correspondingly, Peg-IFNα inhibited cTCRL-Ab-mediated NK cell function by reducing CD16 expression in vitro. scRNA-seq revealed that CD16 downregulation occurred mainly within a dysfunctional CD16hi NK subset exhibiting exhaustion properties. In contrast, an activated CD16hiNK subpopulation (CX3CR1⁺KLRC2–CD16hi) with high cytotoxicity was enriched in patients who experienced favorable treatment responses. Furthermore, the intrahepatic CX3CR1+KLRC2–CD16hi subset tended to exhibit functional restoration in HBsAg-loss individuals. Conclusions Our data contribute to the understanding of antibody-mediated responses of NK cells in chronic HBV infection, and highlight a previously unappreciated functional CX3CR1+KLRC2–CD16hiNK subset as a potential therapeutic target.

Objective: To investigate the association between brain and muscle Arnt like protein 1( BMAL 1) gene and ambulatory blood pressure (ABP) parameters in college students, and to explore the influence of the interaction between the gene and weight status on the ABP levels, so as to provide reference for early prevention of chronic cardiovascular diseases related to hypertension. Methods: During September 2022 to June 2024, a total of 510 college students were recruited from a university in Changsha, China for on site questionnaire investigation, physical examination, ABP monitoring and genotyping testing. Multiple linear regression method was used to explore the association between the BMAL 1 gene and ABP indicators. An interaction term was included in the general linear model of multiple linear regression to analyze the interactive effects of BMAL 1 gene polymorphisms and weight status on ABP levels. Results: The prevalence of abnormal 24 hour blood pressure, abnormal daytime blood pressure, and abnormal nighttime blood pressure were 3.3%, 3.1%, and 3.9%, respectively. Multiple linear regression analysis showed that the BMAL 1/rs7950226 polymorphism was positively correlated with the 24 hour diastolic blood pressure(DBP) and the daytime DBP level after adjusting for gender, age, and body mass index( β =0.87,0.99, both P <0.05). Also, interaction between BMAL 1/ rs 11022775 and weight status on the nighttime DBP level ( P interaction =0.03) was found. The CC genotype carriers had significantly higher nighttime DBP level ( β =3.52, P <0.05) among overweight/obesity college students, but no differences in nocturnal DBP levels were observed between CC genotype carriers and TT+CT genotype carriers among college students with normal body weight( P > 0.05). Conclusions The rs 7950226 polymorphism is associated with 24 hours DBP and daytime DBP levels. Significant interaction between rs 11022775 with weight status on the nighttime DBP level is found among college students.

ObjectiveTo analyze the development trajectory， research hotspots， and trends in medical humanities research in China since the new era. MethodsA search was conducted on the CNKI （China National Knowledge Infrastructure） advanced search page using the themes“medical humanities”or “humanistic medicine，”retrieving a total of 5，758 articles. After applying specific screening criteria， 5，095 articles were included in the analysis. Citespace6.1.R6 was used to visualize and analyze the authors， institutions， and keywords of the 5，095 articles.

Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

Objective:To analyze the impact of serum alpha-fetoprotein (AFP) and carbohydrate antigen 19-9 (CA19-9) on the prognosis of patients with combined hepatocellular-cholangiocarcinoma (CHC) after radical surgery.Methods:Clinical data of 100 patients diagnosed with CHC by postoperative pathology in Hunan Provincial People's Hospital from January 2009 to January 2019 were retrospectively analyzed, including 73 males and 27 females, aged (52.0±10.9) years. Univariate and multivariate Cox regression analysis were conducted to try to find out the effects of AFP and CA19-9 on postoperative disease-free survival (DFS) of patients with CHC. Subgroup analysis was also performed to analyze the DFS among patients with different levels of AFP and CA19-9. Kaplan-Meier method and log-rank test were used to plot and compare the survival curves between groups.Results:Univariate analysis showed that levels of AFP, CA19-9, alanine transaminase, aspartate transaminase, American Joint Committee on Cancer (AJCC) TNM staging, portal vein invasion, tumor number are associated with postoperative DFS in CHC patients (all P<0.05). The multivariate Cox analysis showed that AFP≥20.6 μg/L ( HR=6.686, 95% CI: 1.985-9.582), CA19-9≥35.2 U/L ( HR=5.790, 95% CI: 1.197-8.855), AJCC tumor TNM staging stage Ⅱ( HR=6.384, 95% CI: 2.069-11.532), and portal vein invasion ( HR=2.384, 95% CI: 1.100-10.125) were risk factors for a shortened DFS in CHC patients after surgery (all P<0.05). Subgroup analysis showed that patients with AFP≥20.6 μg/L and CA19-9≥35.2 U/L ( n=14) had a lower DFS compared to patients with AFP<20.6 μg/L and CA19-9≥35.2 U/L ( n=32), and patients with AFP≥20.6 μg/L and CA19-9<35.2 U/L ( n=20) ( χ2=6.23, 4.98, P=0.014, 0.043). Conclusion:AFP and CA19-9 are risk factors for DFS in CHC patients. Patients with AFP≥20.6 μg/L and CA19-9≥35.2 U/L showed a worse prognosis.

Objective To satisfy the normalized disinfection in the orthopedic ward,an air sterilizer based on low-temperature plasma has been developed to investigate its sterilization results in a dynamic environment of hospitalization where patients,companions and medical workers are involved.Methods This study took an orthopedics ward in the Secondary Affiliated Hospital of Xi'an Jiaotong University,as the research object,where a home-made low-temperature plasma air sterilizer was utilized.A six-stage viable Andersen cascade impactor was used to sample the natural bacteria in the ward before and after machine operation for three hours.The species and quantity of bacteria in the ward were analyzed.Results The ozone concentration in the indoor dynamic environment decreased to below 5 ppbv.After three-hour disinfection,the elimination rate of natural bacteria reached 92.35％.The final colony forming unit decreased to～150 CFU/m3;the extinction rates of Staphylococcus hominis,Bacillus cereus,molds,and Micrococcus luteus were 90.48％,80.90％,87.50％,and 92.82％respectively.Even all Haemophilus massiliensis disappeared after two-hour treatment.Conclusion Intermittent disinfection of the dynamic environment in the ward using low-temperature plasma synergistic catalyst has enabled the indoor ozone concentration to reach the first-level national standard line,effectively suppressing secondary pollution caused by ozone leakage while efficiently killing suspended microorganisms in the air,which is close to the disinfection level Ⅰenvironment specified in Hygienic Standard for Disinfection in Hospitals(GB 15982-2012).The results also show that the plasma catalytic synergistic disinfection and sterilization has the technical advantages of efficient disinfection and human-machine coexistence,which can ensure indoor air quality safety,reduce the workload of nursing staff,and thus is an effective method to assist or even replace the existing physical and chemical means.

Objective:To explore the interactive transfer effects between ICU transferred patients' and their primary caregivers' transfer readiness and relocation stress using the Actor-Partner Interdependence Model (APIM) .Methods:A convenience sampling method was used to select 304 pairs of ICU patients and their primary caregivers, who were transferred from the ICU between January and July 2024 at West China Hospital of Sichuan University. A general information questionnaire, ICU patients Transfer Readiness Scale, Relocation Stress Syndrome Scale-Short Form, Caregiver Preparedness Scale, and Family Relocate Stress Syndrome Scale were used to collect data. The APIM was applied to analyze the relationship between ICU patients' and caregivers' transfer readiness and relocation stress.Results:The transfer readiness scores of 304 pairs of ICU patients and their primary caregivers were (65.22±10.04) and (14.57±4.84) , respectively, and the relocation stress scores were (25.06±5.34) and (50.35±7.38) , respectively. APIM analysis showed that the transfer readiness of ICU patients negatively predicted their own relocation stress ( P<0.05) , and the transfer readiness of primary caregivers negatively predicted their own relocation stress ( P<0.05) . The ICU patients' transfer readiness negatively predicted the primary caregivers' relocation stress ( P<0.05) , while the transfer readiness of primary caregivers did not significantly predict the ICU patients' relocation stress ( P>0.05) . Conclusions:ICU patients' relocation stress is influenced by their own transfer readiness, while primary caregivers' relocation stress is jointly influenced by both their own and the patients' transfer readiness. This suggests that healthcare providers should pay attention to the transmission of relocation stress between ICU patients and their families and actively explore family-based intervention strategies.
