ObjectiveTo investigate the mechanisms of Tongnao decoction （TND） in mice with acute ischemic stroke （AIS）. MethodsFifty male C57BL/6J mice were randomly divided into a sham operation group， model group， TND low-dose group （1.86 g·kg^-1）， TND high-dose group （3.72 g·kg^-1）， and butylphthalide （NBP） group （10 mg·kg^-1）， with 10 mice in each group. A mouse model of cerebral ischemic injury was established using photochemical thrombosis （PT）. The sham operation group and model group were administered an equal volume of normal saline by gavage. All five groups were treated once daily for 14 consecutive days. Behavioral tests were performed before modeling and at the end of administration. T₂-weighted imaging （T₂WI） was performed 3 days after modeling to evaluate the extent of injury. Hematoxylin-eosin （HE） staining was used to observe histological changes in the cerebral cortex， and Nissl staining was used to observe neuronal morphology. Cerebral blood flow in mice was detected using a laser speckle contrast imaging （LSCI） system. Immunofluorescence staining was used to detect the cell proliferation marker bromodeoxyuridine （BrdU） and the highly glycosylated type I transmembrane glycoprotein CD34. Western blot analysis was used to detect the expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， glycogen synthase kinase-3β （GSK-3β）， and their phosphorylation levels， as well as tight junction-related proteins zonula occludens-1 （ZO-1）， Occludin， and Claudin-5 in the peri-infarct tissue. Thirty-five zebrafish were randomly divided into normal control group， model group， TND low and high dose groups （0.16， 0.32 g·L^-1） and NBP group （10 μmol·L^-1）， with 7 in each group. A stereoscopic fluorescence microscope was used to observe vascular growth in zebrafish. ResultsImaging showed that PT caused ischemia in the right cortical region. Behavioral tests indicated that， compared with the model group， the drug-treated groups reduced the error rate of irregular balance ladder climbing on the affected side and shortened the tape removal time （P<0.05）. HE staining and Nissl staining showed that， compared with the model group， the drug-treated groups exhibited reduced brain tissue damage， fewer scars， and improved neuronal morphology. LSCI results showed that the drug-treated groups partially restored cerebral blood perfusion and promoted the establishment of collateral circulation compared with the model group. Immunofluorescence staining indicated that the drug-treated groups increased the positive rates of BrdU and CD34 compared with the model group （P<0.01）， promoting angiogenesis. Meanwhile， compared with the model group， the drug-treated groups upregulated the expression levels of p-PI3K， p-Akt， p-GSK-3β， and tight junction proteins ZO-1， Occludin， and Claudin-5 （P<0.05，P<0.01）， and increased the number of intersegmental vessels in zebrafish （P<0.05，P<0.01）. ConclusionTND can promote angiogenesis around the infarct in PT model mice by regulating the PI3K/Akt/GSK-3β signaling pathway， thereby improving cerebral ischemic injury.

ObjectiveTo explore the role of neuroimaging features monitored by functional near-infrared spectroscopy （fNIRS） in postoperative delirium （POD） in elderly patients undergoing joint replacement during perioperative period， and to provide a basis for early clinical prediction. MethodsA total of 105 elderly patients who underwent joint replacement under general anesthesia were included. The Mini-Mental State Examination （MMSE） scale was used to evaluate the patient's cognition one day before the operation. Before the start of the surgery， fNIRS was used to monitor the changes of cerebral blood oxygen saturation when the patient performed the task state. The 3-minute delirium diagnostic scale （3D-CAM scale） was used to evaluate the occurrence of POD at 24， 48 and 72 h after operation. Brain network analysis was performed and Logistic regression analysis was used to explore the relationship between fNIRS monitoring data and POD in elderly patients undergoing joint replacement surgery during preoperative task state. The receiver operating characteristic curve （ROC curve） was constructed to evaluate the diagnostic efficacy， and the Hosmer-Lemeshow goodness-of-fit test was used to test the goodness of fit of the model. ResultsAmong 105 patients， 100 cases were effectively analyzed， of which 20 cases （20%） had POD. Brain network analysis showed that the r value of functional connectivity correlation coefficient in POD group （0.069±0.118） was lower than that in non-POD group （0.073±0.084）. The low channel connectivity of right primary somatosensory cortex-right primary motor cortex （RS1-RM1） and left anterior pole-right Broca's triangle （LFP-RBA44） was an important factor affecting the occurrence of POD （P < 0.05）. Based on this result， the area under the ROC curve was 0.797 and 0.784， respectively. The results of Hosmer-Lemeshow goodness-of-fit test showed that the model fitted well （all P>0.5）. ConclusionThe neuroimaging features extracted from the cerebral oxygen saturation data monitored by fNIRS are significantly correlated with the risk of POD in elderly patients undergoing joint replacement during perioperative period. Among them， the low connectivity of preoperative RS1-RM1 and LFP-RBA44 brain network channels is an important influencing factor of POD occurrence. Predicting the occurrence of POD based on fNIRS is conducive to the early intervention and risk reduction of perioperative complications， improving medical quality and promoting precision medical practice.

ObjectiveTo observe the clinical efficacy of the Yiqi Yangyin Huoxue prescription （YYHP） in the treatment of cathartic colon （CC） and its effects on fecal short-chain fatty acids （SCFAs）， and to explore the correlations among CC severity indicators and between these indicators and patient history. MethodsAccording to the inclusion and exclusion criteria， 98 patients meeting the diagnostic criteria of both traditional Chinese and Western medicine for CC with the syndrome of Qi-Yin deficiency complicated by blood stasis were randomly assigned to an observation group and a control group. The observation group received YYHP granules， while the control group received lactulose. Both medications were administered twice daily， one sachet each time， half an hour after breakfast and dinner， with a treatment course of 8 weeks. The primary constipation symptom score， Patient Assessment of Constipation Quality of Life （PAC-QOL） score， and TCM syndrome score were assessed before and after treatment and at the 8^th week after the end of treatment. The overall clinical effective rate， as well as the efficacy attenuation index and degree， were evaluated. Fecal SCFA levels were measured using gas chromatography-mass spectrometry （GC-MS）. Spearman correlation analysis was performed to explore the correlations among CC severity indicators and between these indicators and patient history. ResultsThe overall clinical effective rate in the observation group （95.83%） was higher than that in the control group （78.72%） （P<0.05）. After treatment， the total scores for primary constipation symptoms， PAC-QOL， and TCM syndromes decreased in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. The severity of all primary constipation symptoms was alleviated in both groups （P<0.05）. In terms of "excessive straining and difficult defecation"， "anal heaviness， incomplete evacuation， and bloating sensation"， "abdominal distension"， and "defecation frequency"， the observation group showed better efficacy than the control group （P<0.05）. Scores of the four PAC-QOL dimensions and the scores and severity of primary and secondary TCM symptoms were reduced in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. After treatment， acetic acid， propionic acid， butyric acid， and total SCFAs in the observation group increased significantly （P<0.05）. The efficacy attenuation index and degree in the observation group were lower than those in the control group （P<0.05）. No severe adverse reactions occurred in either group， and there was no statistically significant difference in the incidence of adverse reactions between the two groups. Positive correlations of varying degrees were observed among the total scores of primary constipation symptoms， PAC-QOL， and TCM syndromes， as well as between these scores and the history of stimulant laxative use， disease duration， and age. ConclusionYYHP can effectively alleviate the primary constipation symptoms in CC patients， improve quality of life， and ameliorate TCM syndromes， with good safety. It also has the advantage of a lower rebound degree after drug withdrawal， and its mechanism may be related to increasing fecal SCFA levels. Long-term abuse of stimulant laxatives may aggravate the severity of CC and prolong the disease course.

Antibody-drug conjugates (ADCs) have emerged as a standard treatment modality for previously treated driver gene-positive advanced non-small cell lung cancer (NSCLC). Sacituzumab tirumotecan (sac-TMT), a novel TROP-2-targeting ADC, has been the focus of the phase Ⅲ clinical trial OptiTROP-Lung04. This trial demonstrated, for the first time, that single-agent sac-TMT significantly improves progression-free survival and overall survival compared with conventional platinum-based chemotherapy in patients with epidermal growth factor receptor (EGFR) mutant advanced NSCLC following resistance to EGFR tyrosine kinase inhibitors. This review combines existing consensus from literature with the latest research evidence to systematically analyze OptiTROP-Lung04 from multiple perspectives, including molecular mechanisms, study design, clinical significance, and safety management. Furthermore, it explores future development directions in an effort to provide new insights into precision therapy for advanced NSCLC.

OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） in non-small cell lung cancer （NSCLC） patients and therapeutic efficacy， with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed， Embase， Cochrane Library， CNKI， Wanfang Data， and CBM were searched from the inception to July 20， 2025. Following literature screening， data extraction and quality assessment， descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies， seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio （NLR）， derived neutrophil-to-lymphocyte ratio （dNLR）， platelet-to-lymphocyte ratio （PLR）， and monocyte-to-lymphocyte ratio （MLR）， higher lymphocyte-to-monocyte ratio （LMR） before treatment， as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR， dNLR， PLR， and interleukin-6 （IL-6）， higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate， while the association of these markers after treatment remained controversial； another study showed that an early decline in NLR， MLR， and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

Colorectal cancer has an insidious onset， and some patients have already developed local invasion or metastasis at the time of diagnosis， which affects treatment strategy selection and survival prognosis. The tumor microenvironment is not only the basic condition for tumor cell survival but also the core regulatory factor driving their local invasion and distant metastasis. This article reviewed the mechanisms by which traditional Chinese medicine regulates the tumor microenvironment to inhibit colorectal cancer metastasis. It was found that traditional Chinese medicine active ingredients such as astragalus polysaccharides， leonurine， kaempferol， etc.， as well as traditional Chinese medicine formulas such as Jianpi jiedu formula， can inhibit colorectal cancer metastasis by regulating key links of the tumor microenvironment， including immunosuppression， inflammatory response， intestinal microecological disorder， abnormal angiogenesis， and extracellular matrix homeostasis imbalance. However， current related research was still mainly based on cell and animal experiments， with limited clinical evidence-based data， and mechanistic studies mostly focued on single signaling pathways. Future research should integrate multi-omics technologies and systems biology methods to systematically elucidate the key targets and action networks through which traditional Chinese medicine regulates the colorectal cancer tumor microenvironment to combat metastasis.

Objective To investigate the effects of bis(acetylacetonato)oxovanadium(IV)[VO(acac)?]on human adrenocortical carcinoma cell lines SW-13 and NCI-H295R in vitro,aiming to determine whether VO(acac)?promotes or inhibits the proliferation,migration,and invasion of these cells.Methods SW-13 and NCI-H295R cells in logarithmic growth phase were exposed to VO(acac)? at concentrations of 6.25,12.5,25,50,75,100,and 200 μmol/L for 24 and 48 hours,respectively.Mitotane served as the positive control.Cell viability was assessed using the CCK-8 assay to evaluate the effects of VO(acac)? on SW-13 and NCI-H295R cells.Subsequently,cells were treated with VO(acac)? at concentrations of 0,6.25,12.5,and 25 μmol/L for 48 hours,and flow cytometry was employed to investigate the impact of VO(acac)? on apoptosis.The migratory ability of the cells was evaluated using a wound healing assay,while their invasive capacity was assessed via a Transwell assay.Additionally,the clonogenic assay was used to determine the proliferative potential of SW-13 and NCI-H295R cells following VO(acac)?treatment.Results The CCK-8 results demonstrated that VO(acac)2 inhibited the viability of SW-13 and NCI-H295R cells in a time-and concentration-dependent manner.Specifically,the half-maximal inhibitory concentra-tions(IC50)for VO(acac)2 against SW-13 cells were 62.98±6.67 μmol/L after 24 hours and(14.61±1.66)μmol/L after 48 hours of treatment,while the corresponding IC50 values for NCI-H295R cells were 46.78±7.89 μmol/L and 12.61±2.98 μmol/L,respectively.Flow cytometry analysis revealed that VO(acac)2 induced apoptosis in both SW-13 and NCI-H295R cells in a concentration-dependent manner(P<0.05).The wound healing assay indicated a significant reduction in the migratory rate of SW-13 and NCI-H295R cells with increasing concentrations of VO(acac)2(P<0.05).Transwell assay results showed that VO(acac)2 significantly inhibited the invasive ability of SW-13 and NCI-H295R cells in a concentration-dependent fashion.Finally,the clonogenic assay confirmed that VO(acac)2 suppressed the proliferative capacity of SW-13 and NCI-H295R cells in a concentration-dependent manner.Conclusion VO(acac)2 inhibits the proliferation,migration,and invasion of human adrenocortical carcinoma cells(SW-13 and NCI-H295R),while inducing apoptosis in these cell lines.

Objective:To explore the effect of hypnotherapy combined with mindful decentering technique in treating generalized anxiety disorder(GAD).Methods:A total of 7 sessions of hypnotherapy combined with mindful decentering technique were conducted in a patient with GAD,primarily utilizing mindful decentering induction,hyp-notic regression,and ego state therapy.Changes were evaluated before treatment,1 week after treatment,and 9 months after treatment using the Symptom Checklist-90(SCL-90),Self-Rating Anxiety Scale(SAS),Pittsburgh Sleep Quality Index(PSQI),and Mindfulness Attention Awareness Scale(MAAS).Results:After treatment,the patient's anxiety state and accompanying insomnia symptoms improved significantly,with stable results observed during multiple follow-ups over 14 months.Scores of SCL-90,SAS,and PSQI decreased significantly,while the scores of MAAS increased in the short term(Ps＜0.05).Conclusion:Hypnotherapy combined with mindful decen-tering technique has been effective in treatming GAD in this case,with stable outcomes overtime.

Objective To investigate the expression level of centromere protein(CENP)Ⅰin lung adenocarcinoma cells,to study the effects of CENPⅠon the proliferation,invasion,migration,apoptosis,and epithelial-mesenchymal transition(EMT)of lung adenocarci-noma cells,and to explore the possible mechanisms related to its occurrence.Methods The expression of CENPⅠmRNA and protein in four types of lung adenocarcinoma cells and normal alveolar epithelial cells were detected by quantitative real-time polymerase chain reaction(RT-qPCR)and Western blotting.The expression of CENPⅠin H1650 cells was knocked down by the siRNA technique,The transfection efficiency was detected by RT-qPCR and Western blotting.The effects of knock-down CENPⅠon proliferation,cell cycle,apoptosis,invasion and migration of H1650 cells were detected by the cell counting kit-8 assay,the transwell assay,and flow cytometry.Western blotting was used to detect the expression of E-cadherin,N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,PI3K,AKT,mTOR,p-PI3K,p-AKT,and p-mTOR.Results After the knock-down of CENPⅠ,the proliferative ability of the H1650 cells significantly decreased,the number of apoptotic cells significantly decreased,and the cell invasion and migration abilities significantly decreased(P<0.01).E-cadherin expression was upregulated and N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,p-PI3K,p-AKT,and p-mTOR expres-sion were down-regulated in the CENTI group compared with the control group(P<0.05).The expression of p-PI3K,p-AKT,and p-mTOR in the si-CENPⅠ+IGF-1 group was upregulated compared to that in the si-CENPⅠgroup(P<0.05).Conclusion High expression of CENPⅠin lung adenocarcinoma cells promotes the proliferation,invasion,and migration of lung adenocarcinoma H1650 cells and EMT inhibits apoptosis,which may be related to the activation of the PI3K/AKT/mTOR signaling pathway.

Objective:Based on data from the Global Burden of Disease Study 2021 (GBD 2021), this study aims to analyze the epidemiological trends of inflammatory bowel diseases (IBD) in China from 1990 to 2021 and to assess the projected disease burden.Methods:Data on incidence, prevalence, mortality, and disability-adjusted life years (DALY) for IBD in China from 1990 to 2021 were extracted from the GBD 2021 database. Annual percent change (EAPC) and Bayesian age-period-cohort (BAPC) analyses were employed to evaluate these trends. Additionally, predictions for the disease burden over the next 25 years were made.Results:The age-standardized incidence rate of IBD in China rose from 0.74 per 100 000 in 1990 to 1.40 per 100 000 in 2021, an 89.19% increase. The age-standardized prevalence rate increased from 5.59 per 100 000 in 1990 to 9.16 per 100 000 in 2021, marking a 63.86% rise. Conversely, the age-standardized case fatality rate decreased from 0.75 per 100 000 in 1990 to 0.33 per 100 000 in 2021, a reduction of 56.00%. The total DALYs decreased from 162 186 in 1990 to 136 932 in 2021, a decline of 15.57%, while the age-standardized DALY rate fell from 18.38 per 100 000 in 1990 to 7.68 per 100 000 in 2021, a decrease of 58.22%. Analysis by age group revealed that the age-standardized incidence rate for the 35-39 years cohort increased most significantly, with an EAPC of 3.23%. The age-standardized prevalence rate for the 50-54 years cohort increased most significantly, with an EAPC of 2.85%. Gender analysis indicated that from 1990 to 2021, the age-standardized prevalence rate was higher among females than males, but the age-standardized case fatality rate rate was higher among males. From 2004 to 2021, the age-standardized DALY rate declined for both sexes, though it remained higher in males. By 2046, the number of new cases is projected to be slightly higher in males, while case fatality rate and DALYs are expected to remain low for both genders.Conclusions:Over the past three decades, the disease burden of IBD in China has increased significantly, particularly in terms of incidence and prevalence. Despite a general decrease in case fatality rates, the burden of IBD may increase in the elderly population due to aging demographics. Therefore, effective preventive measures, early screening, and aggressive treatment are crucial, especially for the elderly.
