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.

Background Microparticles (MPs) are one of the main medium of inflammatory reaction with an important role in atherosclerotic progression. Studies on association of air pollution exposure and levels of peripheral blood MPs are limited among human. Objective To evaluate the effects of short-term exposure to air pollution on levels of peripheral blood MPs. Method A panel of 73 healthy adults was followed with 4 repeated follow-ups in Beijing, China, from November 2014 to January 2016. During each visit, we collected questionnaire information, fasting venous blood, urine, and exposures to fine particulate matter (PM2.5), black carbon, nitric oxide, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon monoxide, and ozone. We used linear mixed-effect models to analyze associations of air pollution exposure with levels of total MPs (TMPs) and MPs derived from various cells. Stratified analysis was conducted by levels of C-reactive protein (CRP) and malondialdehyde (MDA). Results The results showed significant associations between air pollution exposure and peripheral blood TMPs at 2 h-6 d prior to the follow-ups (P<0.05), while no statistical associations were found for MPs derived from different cell types. Significant increases in TMPs of 7.8% (95%CI: 0.7%, 15.3%) and 14.3% (95%CI: 2.8%, 27.2%) were observed with each interquartile range (IQR) increase in PM2.5 (IQR=64.9 μg·m−3) at prior 18 h and NO (IQR=40.5 μg·m−3) at prior 48 h. Among participants with low levels of CRP and MDA, significantly positive associations were observed between air pollution exposure and levels of TMPs (P<0.05). Conclusion Short-term exposure to air pollution is significantly associated with increased levels of circulating MPs in healthy adults, and in people with lower systemic inflammation, peripheral blood MPs levels are more easily affected after exposure to air pollutants.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

ObjectiveTo investigate the effect of Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma on ferroptosis in the rat model of myocardial infarction and further elucidate its role in myocardial remodeling. MethodsThe rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. The 50 successfully modeled rats were randomly divided into model group, ferroptosis inhibitor group (2 mg·kg-1), enalapril group (2.1 mg·kg-1), and low- and high-dose (4 g·kg-1 and 8 g·kg-1, respectively) Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma, with 10 rats in each group. The rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. After 4 weeks of treatment, echocardiography was used to assess the cardiac structure and function. Hematoxylin-eosin (HE) staining and Masson staining were employed to observe pathological morphology and fibrosis of the myocardial tissue. Serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), transforming growth factor-β (TGF-β), and myosin heavy chain-β (MHC-β) were measured by enzyme-linked immunosorbent assay (ELISA). Prussian blue staining was performed to detect myocardial iron deposition. The myocardial mitochondrial structure was observed by transmission electron microscopy. Levels of malondialdehyde (MDA) and glutathione (GSH) in the myocardial tissue were determined by lipid peroxidation assay kits. Immunofluorescence assay was conducted to observe the fluorescence intensity of nuclear factor E2-related factor 2 (Nrf2) in the myocardial tissue. Western blot analysis was performed to evaluate the expression levels of proteins in the Nrf2/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway. ResultsCompared with the sham group, the model group showed increased left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), and serum levels of NT-proBNP, TGF-β, and MHC-β (P<0.01), decreased left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01), disarrangement of myocardial cells, inflammatory cell infiltration, severe myocardial fibrosis, increased myocardial iron deposition, and irregular mitochondrial morphology with vacuolation. Furthermore, the modeling led to increased MDA (P<0.01), decreased GSH (P<0.01), diminished Nrf2 fluorescence intensity in the myocardial tissue, and downregulated expression levels of Nrf2, SLC7A11, and GPX4 (P<0.01). Compared with the model group, Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma reduced the LVEDD, LVESD, and serum levels of NT-proBNP, TGF-β, and MHC-β (P<0.05, P<0.01), increased the LVEF and LVFS (P<0.05, P<0.01), alleviated pathological changes such as myocardial cell disarrangement, inflammatory cell infiltration, myocardial fibrosis, and iron deposition, lowered the level of MDA (P<0.05, P<0.01), raised the level of GSH (P<0.05, P<0.01), improved the mitochondrial morphology and reduced vacuolation in the myocardial tissue, enhanced Nrf2 fluorescence intensity, and upregulated the expression levels of Nrf2, SLC7A11, and GPX4 (P<0.05, P<0.01) in the rat model of myocardial infarction. ConclusionGardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma alleviates pathological damage and myocardial remodeling in the rat model of myocardial infarction by inhibiting ferroptosis, the mechanism of which is related to the activation of Nrf2/SLC7A11/GPX4 signaling pathway.

Objective :
To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN).
Methods :
Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays.
Results :
Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01).
Conclusion
Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

Objective:To investigate the clinical characteristics of cervical adenocarcinoma and analyze the survival status and related prognostic factors.Methods:The data of 229 patients with cervical adenocarcinoma who were diagnosed pathologically in the General Hospital of Ningxia Medical University from January 2013 to October 2022 were retrospectively analyzed. Among them, 198 early stage patients were mainly treated with surgery, and 31 locally advanced stage patients were mainly treated with chemoradiotherapy. The overall survival (OS) and progression-free survival (PFS) rates in the whole cohort of patients and different treatment subgroups were calculated. Kaplan‐Meier method and log‐rank test were used for survival analysis, and Cox proportional hazards model was used for univariate and multivariate survival analyses.Results:Among the 229 patients, there were 11 subtypes of pathological classifications, predominantly of the usual‐type. At the end of follow‐up, 57 patients (24.9%) relapsed. The 3‐ and 5‐year OS rates were 86.4% and 79.3%, respectively, and the 3‐ and 5‐year PFS rates were 81.6% and 73.6%, respectively. Multivariate analysis showed that International Federation of Gynecology and Obstetrics (FIGO) staging of stages Ⅲ‐Ⅳ was an independent prognostic factor for OS and PFS ( HR=2.033, 95% CI=1.456‐2.839, P<0.001; HR=1.701, 95% CI=1.251‐2.313, P=0.001). Lymph node metastasis was an independent risk factor for PFS ( HR=1.610,95% CI=1.021‐2.539, P=0.041). Subgroup analysis of 198 patients with surgical treatment: the 3‐ and 5‐year OS rates were 90.0% and 84.9%, and the 3‐ and 5‐year PFS rates were 82.7% and 76.7%, respectively. Multivariate analysis showed that lymph node metastasis and deep invasion depth were the main risk factors for OS ( HR=6.893, 95% CI=2.592‐18.327, P<0.001; HR=1.952, 95% CI=1.164‐3.272, P=0.011) and PFS ( HR=5.507, 95% CI=2.569‐11.805, P<0.001; HR=1.638, 95% CI=1.09‐2.461, P=0.018). Ovarian preservation was an independent risk factor for PFS ( HR=3.364, 95% CI=1.115‐10.151, P=0.031). Conclusions:The pathological types of cervical adenocarcinoma are complex and diverse. Local recurrence and distant metastasis are the main reasons for treatment failure. FIGO stage, lymph node metastasis and postoperative depth of invasion are the main prognostic factors of cervical adenocarcinoma.

Purpose The study aimed to analyze the relationship between MET gene variants and clinicopathologi-cal features in patients with non-small cell lung cancer(NSCLC).Methods Next-generation sequencing technology was used to detect MET gene variants in NSCLC specimens.The association between MET gene variant status and clini-copathological features was then analyzed.Results Among 1 633 cases of NSCLC,the overall MET mutation rate was 4.53%(74/1 633).Variants were mainly observed in male patients,never-smokers,those older than 60 years,ade-nocarcinoma histology,and patients with TNM stage Ⅲ+Ⅳ disease(P<0.05).MET gene variant status showed no significant assocication with patient age,sex,smoking history,or pathological subtype(P>0.05),but was statistical-ly correlated with clinical stage and presence of distant metastasis(P<0.05).The two major variant types were MET exon 14 skipping and MET amplification,which together accounted for 71.62%of all variants.In addition,MET am-plification was positively correlated with EGFR(P=0.003,rs=0.340)and TP53 mutations(P=0.002,rs=0.362),but showed no correlation with KRAS or ALK gene mutations.In contrast,MET exon 14 skipping was nega-tively correlated with EGFR gene mutations(P<0.001,rs=-0.409),and showed no significant correlation with KRAS,ALK,or TP53 mutations.Conclusion Different types of MET gene variants(amplification,exon 14 skip-ping,fusion,and others)are significantly associated with clinical advanced clinical stage and distant metastasis in NSCLC,but are independent of patient age,sex,smoking history,and pathological subtype.MET amplification fre-quently co-occur with EGFR and TP53 co-mutations.

Objective:To explore the effect of exercise on the memory of rats modeling vascular cognitive impairment (VCI) and also its effects on the hippocampal Sema3G/neuropilin-2 (Nrp2)/PlexinA4 signaling pathway.Methods:Eighteen male Sprague-Dawley rats were randomly divided into a sham-operated group, a model group, and an exercise group, each of 6. The model and exercise groups underwent VCI modeling via bilateral common carotid artery occlusion, while the sham-operated group received the same surgical procedure without vessel ligation or transection. Beginning forty-eight hours after the surgery, the exercise group carried out daily 30-minute treadmill training sessions, 5 days a week, for a total of 4 weeks, while the other two groups were placed on the same treadmill with it not in operation. After the intervention, cognitive functioning was assessed using the novel object recognition (NOR) test and a Y-maze test. Western blotting was employed to evaluate the expression of Sema3G, Nrp2, PlexinA4, and Rac1 in the hippocampus. Immunofluorescence staining was used to observe the distribution of Nrp2 and PlexinA4 in the hippocampus.Results:Compared with the model group, the exercise group exhibited significantly higher NOR indices during both the short-term and long-term memory testing phases after the intervention. Those rats also tended to have significantly longer total exploration times in the novel arm of the Y-maze test. The western blotting revealed that the expression levels of Sema3G, PlexinA4, and Rac1 in the hippocampus were significantly higher in the exercise group compared to the model group, on average. Immunofluorescence showed significantly increased PlexinA4 fluorescence intensity in the CA1, CA3, and dentate gyrus (DG) regions of the hippocampus, and significantly elevated Nrp2 fluorescence intensity in the CA3 region in the exercise group compared to the model group. The Pearson correlation coefficients for Nrp2/PlexinA4 co-localization in the CA1, CA3 and DG regions were significantly higher in the exercise group than in the model group.Conclusions:Exercise training significantly improves memory function in rats with VCI, and this effect may be associated with activation of the hippocampal Sema3G/Nrp2/PlexinA4 signaling pathway.
