OBJECTIVE To introduce the development of an intelligent prescription review decision-support system for anti-tumor drugs and assess its clinical application outcomes. METHODS Relevant data sources， including national and local pharmaceutical administration policies， clinical practice guidelines/consensus， hospital information systems data， and genetic testing results， were integrated. Adhering to the principles of structure， standardization and dynamic updating， a knowledge base covering chemotherapeutic， targeted and immunotherapeutic agents was constructed using a dual-dimensional modeling approach that combined “drug attributes” and “clinical contexts”. This knowledge base was then embedded into the hospital’s electronic medical order system to establish the prescription review decision-support system. The application and performance of the system were evaluated at Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. RESULTS A knowledge base containing 18 318 prescription review rules for anti-tumor drugs was constructed， and a closed-loop prescription review system was successfully established， encompassing pre-prescription real-time intervention， in-process interactive review， and post-prescription evaluation and analysis. From 2021 to 2024， the system generated a total of 57 879 alerts for prescriptions of five typical categories of anti-tumor drugs. For platinum-containing prescriptions， 22 577 alerts were generated， with Cisplatin for injection （lyophilized） being the most frequently alerted drug （13 445 alerts）， and “ototoxicity risk due to combined use” alerts remained high （7 682 alerts）. For methotrexate-containing prescriptions， 3 721 alerts were recorded， primarily related to “precaution-related issues” （76.4%， 2 843/3 721）. For doxorubicin-containing prescriptions， 17 301 alerts were triggered， primarily related to “dosage and administration” （14 315 alerts）. For human epidermal growth factor receptor 2-targeted agents-containing prescriptions， 1 007 alerts were issued， mostly related to “reimbursement restrictions” （956 alerts）. For programmed death-1/programmed death-ligand 1 inhibitors-containing prescriptions， the alerts increased year by year， totaling 13 273 alerts， primarily related to “inappropriate indication” （9 118 alerts）. Over the 4 years， the physician response rates to system alerts were 21.4%， 27.1%， 33.5% and 51.6%， respectively. CONCLUSIONS An intelligent decision-support system for anti-tumor drug prescription review， encompassing a closed-loop process of “real-time pre-event intervention， interactive in-event prescription review， post-event evaluation and analysis”， has been successfully constructed and implemented throughout the entire workflow. There is a discernible trend in this hospital， where the focus on monitoring anti-tumor drugs is shifting towards immunotherapy drugs. Additionally， the acceptance rate of physicians regarding prescription review opinions has been steadily increasing year by year.

Hepatic fibrosis is a complex dynamic process caused by multiple chronic pathogenic factors， characterized by excessive accumulation of liver extracellular matrix and abnormal liver structure and function. If anti-fibrotic treatment is not performed in time， it can progress to liver cirrhosis and even liver cancer. Hepatic fibrosis has a complex pathogenesis， and previous studies mainly focused on the activation of hepatic stellate cells. Recent studies have shown that myeloid cells have the potential of multi-directional differentiation and can also participate in the development and progression of hepatic fibrosis. This article systematically reviews the role and regulatory mechanism of myeloid cells in hepatic fibrosis， in order to provide a reference for clinical diagnosis and targeted therapy.

OBJECTIVE To establish a quality control method for Jinbei oral liquid based on multi-wavelength switching high performance liquid chromatography （HPLC） fingerprint， chemical pattern recognition and multi-index content determination. METHODS A total of 15 batches of Jinbei oral liquid were used as test samples. The Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （ Version 2012 ） was adopted to establish multi-wavelength switching HPLC fingerprints， followed by chromatographic peak identification and similarity evaluation. Cluster analysis， principal component analysis and orthogonal partial least squares-discriminant analysis were applied to conduct chemical pattern recognition on the 15 batches of samples. The multi-wavelength switching HPLC method was used to simultaneously determine the contents of neochlorogenic acid， chlorogenic acid， cryptochlorogenic acid， forsythoside A， baicalin， salvianoli c acid B and wogonoside in samples. RESULTS A total of 25 common peaks were calibrated in the fingerprints of 15 batches of Jinbei oral liquid， among which 7 common peaks were unambiguously identified. The similarity of all samples was higher than 0.960. Chemical pattern recognition results showed that samples S1-S8 were clustered into group 1， and samples S9-S15 were clustered into group 2. Baicalin， wogonoside， neochlorogenic acid， chlorogenic acid and salvianolic acid B were identified as the differential quality markers. The average contents of neochlorogenic acid， chlorogenic acid， cryptochlorogenic acid， forsythoside A， baicalin， salvianolic acid B and wogonoside in 15 batches of Jinbei oral liquid were 0.213 7， 0.085 3， 0.104 9， 0.287 3， 0.420 1， 0.062 1， 0.176 0 mg/mL， respectively. CONCLUSIONS The established quality control method for Jinbei oral liquid combining multi-wavelength switching HPLC fingerprint， chemical pattern recognition and multi-index content determination is stable and reliable， which can provide a reference for the formulation of quality standards of this preparation.

Objective To investigate the epidemiological characteristics of respiratory syncytial virus (RSV) infection in elderly patients at a hospital in Hengshui and its correlation with climatic and environmental factors. Methods A retrospective study was conducted on 826 elderly patients with RSV infection who were hospitalized in the Department of Respiratory and Critical Care Medicine Department of Hengshui People's Hospital from June 2022 to May 2024. Clinical data of the patients were collected. Based on the climatic and environmental data of the Hengshui region during the same period, the epidemiological characteristics of RSV in the elderly population were analyzed. Pearson analysis was used to examine the correlation between RSV incidence and climatic and environmental factors. Results Among the 826 elderly RSV infected patients, males (54.24%) had a higher incidence than females (45.76%). The age of onset was highest in elderly people aged ≥ 80 (39.47%), followed by the age group of 70-79 (32.08%). Cough (89.95%) and sputum (71.19%) were the main clinical symptoms of elderly RSV infected patients. 28.57% of the elderly patients with RSV infection had basic diseases, of which the patients with diabetes accounted for the highest proportion (12.35%), followed by cardiovascular diseases (10.41%). The proportion of patients with mixed infections reached 4.60%, and the proportion of patients with other systemic complications reached 1.69%. From the perspective of the season of onset, the number of elderly RSV cases was highest in spring and winter, accounting for 39.47% and 47.09%, respectively. The correlation analysis results showed that the number of elderly RSV cases was negatively correlated with average wind speed (r=-0.196), average temperature (r=-0.731), and average humidity (r=-0.729), and weakly positively correlated with average atmospheric pressure (r=0.085) (all P<0.05). Conclusion In the elderly population, RSV infection is more prevalent among males and the very old, with a higher incidence during the winter and spring seasons, and is closely related to climate changes in the Hengshui region.

ObjectiveTo investigate whether the inhibitory effect of Panax quinquefolium saponins （PQS） on non-small cell lung cancer （NSCLC） is enhanced under graphene-mediated far-infrared therapy （GFIR）， and to analyze its relationships with mitochondrial dysfunction， mitochondrial DNA （mtDNA） leakage， and the activation of cyclic GMP-AMP synthase （cGAS）/stimulator of interferon genes （STING） signaling pathways. MethodsIn the cell experiments， the cell-counting kit 8 （CCK-8） was employed to assess the inhibitory effects of PQS alone or in combination with GFIR （PQS+GFIR） on A549 cell viability. The scratch assay and the colony formation assay were adopted to evaluate cell migration and colony formation capabilities， respectively. Flow cytometry was employed to assess apoptosis， mitochondrial membrane potential， and reactive oxygen species （ROS） levels. Immunofluorescence （IF） assay was performed to assess mitochondrial localization. Real-time polymerase China reaction（PCR） was used to detect mitochondrial DNA （mtDNA） leakage. A STING knockdown cell model was established by transfecting cells with small interfering RNA （siRNA）， and the knockdown efficiency was assessed by Real-time PCR and Western blot. The cell viability and apoptosis following gene knockdown were assessed through the CCK-8 assay and flow cytometry. In the animal experiments， an allogeneic xenograft mouse model was established with Lewis lung cancer cells. Mice were randomized into a control group， a model group， a cisplatin group， a low-dose PQS （PQS-Low， 90 mg·kg^-1） group， a high-dose PQS （PQS-High， 180 mg·kg^-1） group， a low-dose PQS combined with GFIR （PQS-Low+GFIR， 90 mg·kg^-1） group， and a high-dose PQS combined with GFIR （PQS-High+GFIR， 180 mg·kg^-1） group. Treatment lasted for 14 days， and the fluorescence intensity was monitored at the tumor site by small-animal in vivo imaging during the treatment period. Flow cytometry was utilized to determine the proportions of T-lymphocyte subsets， B-lymphocyte levels， and peripheral blood NK cell levels in the spleens of mice. Immunohistochemical （IHC） staining was performed to assess the infiltration of CD3⁺， CD4⁺， and CD8⁺ T-lymphocytes in the tumor tissue. Enzyme-linked immunosorbent assay （ELISA） was conducted to measure the levels of interferon-α （IFN-α）， interferon-β （IFN-β）， tumor necrosis factor-α （TNF-α）， and interleukin-6 （IL-6） in mouse tumors. The mRNA levels of cGAS， STING， TANK-binding kinase 1 （TBK1）， interferon regulatory factor 3 （IRF3）， interferon beta 1 （IFNB1）， and nuclear factor κB p65 （NF-κB p65） were determined by Real-time PCR. The protein levels of cGAS， STING， p-STING， TBK1， p-TBK1， IRF3， p-IRF3， NF-κB p65， and p-NF-κB p65 were quantified via Western blot. ResultsThe cell experiment results showed that compared with the control group， PQS inhibited the viability and migration of A549 cells， promoted apoptosis， affected mitochondrial localization， reduced mitochondrial membrane potential， increased the ROS level， and promoted mtDNA leakage. Following STING knockdown， the reductions in cell viability and the apoptosis-inducing effects caused by PQS were partially reversed （P<0.05， P<0.01）. Compared with the PQS group， the PQS+GFIR group showed inhibited A549 cell migration and colony formation， exacerbated apoptosis， downregulated mitochondrial membrane potential， elevated ROS levels， and promoted mtDNA leakage. After STING knockdown， the reduced A549 cell viability and abnormal apoptosis phenotype were further reversed （P<0.05， P<0.01）. The animal experiment results showed that compared with the control group， the model group mice exhibited reduced proportions of T-lymphocyte subsets， CD19⁺ B-lymphocyte levels， and peripheral blood NK1.1⁺ cell levels in the spleen （P<0.01）. Compared with the model group， the PQS group showed increased immune cell parameters in mice （P<0.05， P<0.01）. Compared with the PQS group， the PQS+GFIR group exhibited enhanced levels of the aforementioned indicators （P<0.01）. Compared with the model group， the PQS group showed significantly reduced fluorescence intensity in transplanted tumors， significantly upregulated expression of CD3 and CD4 in the tumor tissue， elevated levels of IFN-α and IL-6 in tumors， and upregulated mRNA levels of cGAS， STING， TBK1， IRF3， IFNB1， and NF-κB p65 as well as upregulated protein level of cGAS and phosphorylation level of STING in tumors （P<0.05， P<0.01）. Compared with the PQS group， the PQS+GFIR group demonstrated further reduced tumor fluorescence intensity， elevated levels of CD3， CD4， and CD8 as well as cytokine levels in tumor tissue， and upregulated mRNA levels of genes related to the cGAS/STING pathway as well as upregulated protein level of cGAS and phosphorylation levels of STING， TBK1， IRF3， and NF-κB p65 （P<0.05， P<0.01） ConclusionGFIR enhances the inhibitory effect of PQS on NSCLC， potentially through mitochondrial dysfunction， mtDNA leakage， and activation of the cGAS/STING signaling pathway.

Arson is classified as a violent crime,and often involves accelerants that significantly increase casualties and property damage.These accelerants,typically flammable liquids with low saturated vapor pressure,present volatile characteristic components in fire residues,making evidence preservation critical for accurate forensic analysis.In this study,the preservation performance of AMPAC(American KAPAC polyester sampling bags)and polyethylene(PE)evidence bags were evaluated under simulated field conditions(40 oC)through gas chromatography-mass spectrometry(GC-MS)technique,focusing on background interference,sealing integrity,and cross-contamination.The results demonstrated that AMPAC bags exhibited minimal background interference(C12?C14 alkanes detected after 3?7 days)and effective gasoline sealing,though slight losses of C2?C3 alkylbenzenes and trace cross-contamination were observed.In contrast,PE bags showed significant background hydrocarbons(C15?C19 alkanes)and pronounced gasoline component losses,including C2?C4 alkylbenzenes,naphthalenes,and indenes.Notably,severe cross-contamination of gasoline markers was detected in adjacent blank PE bags,with characteristic components such as C2?C4 alkylbenzenes,naphthalenes,methylnaphthalenes,dimethylnaphthalenes,indenes,indanes,methylindenes,and dimethylindenes identified,indicating substantial cross-contamination issues in PE evidence bags.Microstructural analysis revealed superior sealing in AMPAC bags attributed to their smooth,dense surface morphology compared to PE's rougher,porous structure.This study established a comprehensive evaluation framework for fire residue evidence containers,and found that PE bags were unsuitable for long-term gasoline evidence preservation due to compromised integrity.These findings provided critical references for forensic container selection in fire investigations.

Autism spectrum disorder(ASD),characterized by unknown etiology and high heterogeneity,ne-cessitates precise diagnostic and intervention strategies.Neuroimaging techniques have shown great promise in un-covering the neural mechanisms of ASD,providing a foundation for aided diagnosis and transcranial magnetic stim-ulation(TMS)interventions.This review highlights that integrating multimodal neuroimaging and developing indi-vidualized indices with developmental specificity can significantly improve the accuracy of ASD diagnosis and clas-sification.Furthermore,TMS interventions guided by functional connectivity derived from functional magnetic reso-nance imaging(fMRI)offer a personalized approach to ASD treatment.
