AIM:Hepatotoxicity of Brucea javani-ca picryl with broad-spectrum anticancer effect in nude mice based on hepatic drug metabolizing en-zyme CYP450 activity.METHODS:Fifty-six nude mice were randomly divided into blank group,Bru-cea javanica low-dose group(2 mg/kg),Brucea ja-vanica high-dose group(4 mg/kg),and cisplatin group(2 mg/kg),with 14 mice in each group.The blank group was injected with the same amount of normal saline every 3 days for 6 weeks.Calculate the mortality rate of nude mice in each group,ob-serve the general growth state of nude mice,re-cord the weight change of nude mice before and af-ter administration,weigh and record the liver weight after taking materials,and calculate the liv-er coefficient(liver weight/weight mass×100％),ob-serve and record the liver color and morphology.Hematoxylin-eosin(HE)staining was used to ob-serve the pathological changes of liver tissue.De-tection of alanine aminotransferase(ALT),aspar-tate aminotransferase(AST),lactate dehydrogenase(LDH),alkaline phosphatase(AKP)and albumin(ALB)levels in serum of nude mice by ELISA.Real-time PCR and Western blot were used to detect the mRNA and protein expression levels of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6 and CYP2C9,which were key enzymes of drug metabolism in nude mice liver.RESULTS:Compared with the blank group,the mortality rate of nude mice in the low-dose Brucea javanica bitter alcohol group was 0,the growth state was good,the diet,movement,and mental state were normal,the weight change and liver coefficient ratio were consistent,the liver color was ruddy,the liver lobule morphology was complete under the microscope,the structure was clear,the liver cells were arranged regularly,and there was no inflammatory cell infiltration.There was no significant difference in the content of ALT,AST,LDH,AKP,and ALB.There was no significant difference in the mRNA and protein expression of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9(all P＞0.05).Compared with the blank group,the mortality rate of nude mice in the high-dose group of Brucea javanica bitter alcohol was 14.3％,the growth state was slightly poor,the diet,movement,and mental state were reduced,the weight growth was slow,the liver coefficient ratio was increased,the liver color was reddish brown,some liver lobule boundaries were unclear,a small number of liver cells were loosely arranged,the contents of ALT,AST,LDH,AKP,and ALB were signif-icantly increased,the mRNA levels of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9 were significantly reduced,and the protein expres-sions of CYP2E1,CYP3A11,CYP1A2,and CYP2D6 were significantly reduced(all P＜0.05 or P＜0.01),but there was no statistical difference in the mRNA and protein expression of CYP2C19,and the pro-tein expression of CYP2C9(P＞0.05).Compared with the blank group,the mortality rate of nude mice in the cisplatin group was 35.7％,the growth state was poor,the diet,action,and mental state were low,the weight gain was less,the liver coefficient ratio was significantly increased,the liver color was dark red,the liver sinusoids and central veins were congested,the hepatocytes were disordered,the nuclei were consolidated and contracted,and the arrangement was loose,the contents of ALT,AST,LDH,AKP,and ALB were significantly increased,and the mRNA and protein expressions of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9 were significantly reduced(all P＜0.05 or P＜0.01).CONCLUSION:The dose of Brucea javanica bitter alcohol is correlated with hepatotoxicity to nude mice.High doses of Brucea javanica bitter alcohol have hepatotoxicity to nude mice,which may be re-lated to reducing serum levels of ALT,AST,LDH,AKP,and ALB,inhibiting the expression of multiple subtypes of enzymes in the key enzyme CYP450 of liver drug metabolism,and then reducing the me-tabolism of toxic substances.

Cancer incidence in China has been rising steadily,with a particularly heavy burden from several high-prevalence malignancies.Medical examination for cancer plays a critical role in the early detection of cancer,precancerous lesions,and precursor conditions,thereby facilitating timely diagnosis and intervention.Such examination also addresses the growing demand for person-alized cancer screening services among diverse population groups.The development of evidence-based,context-specific cancer screening guidelines is essential to enhance the standardization,quality,and equity of preventive screening practices across the country,ultimately improving out-comes in early cancer detection and treatment.Guided by the Department of Medical Emergency Response of the National Health Commission,the Guidelines for Medical Examination for Cancer in Health Examination Agency(2025 Edition)were developed under the leadership of the National Cancer Center.A multidisciplinary panel of experts formulated the guidelines in accordance with the principles and methodology of the World Health Organization Handbook for Guideline Deve-lopment.The guidelines provide evidence-based recommendations on key clinical domains:target cancers and populations,overall screening workflow,screening protocols,diagnostic technolo-gies,result interpretation,follow-up procedures,and quality control.The primary objective is to standardize cancer screening practices in health examination agency and strengthen China's ca-pacity for prevention and control of high-burden cancers.

Objective To propose a high-precision deep learning-based image assessment method of osteosarcoma chemotherapy efficacy for clinical treatment,as existing methos have low accuracy of osteosarcoma assessment.Methods The low incidence of osteosarcoma led to the small scale of its imaging data and the problem of imbalance in data categories.This study combined deep learning with clinical medical information,combined the bone sarcoma generation module of BoneGAN and the scale lesion information capture module,and proposed OMLA-Net,a deep learning assessment network for chemotherapy effect of bone sarcoma based on multi-scale lesion attention network,which achieved computer-aided bone tumor assessment with integrated data augmentation and focused lesion information through pre-training and generalized loss training.Results In this study,40 cases of osteosarcoma MRI data were used as the basis for the comparison test on the generated dataset,and the OMLA-Net assessment outperformed the SOTA method Conv-LSTM-GAN in terms of the assessment effects such as accuracy and F1 scores,and the difference was statistically significant(Bootstrap statistical method P＜0.05);the subsequent K-fold cross-validation ablation experiments further demonstrated the effectiveness of each module proposed by OMLA-Net.Conclusion OMLA-Net can effectively perform the impact assessment of chemotherapy effect on osteosarcoma,which provides a new idea for subsequent clinical application.

Objective To investigate the protective effect of long non-coding RNA(lncRNA)small nucleolar RNA host gene 12(SNHG12)on neuronal damage induced by oxygen glucose deprivation/reoxygenation(OGD/R)by targeting microRNA(miR)-140-3p.Methods Human cortical neurons(HCN)were used to establish an OGD/R model,which was separated into OGD/R group,negative control(NC)group,SNHG12 group,SNHG12+miR-NC group,and SNHG12+miR-140-3p mimics group.Normal cultured HCN were also taken as the control(Ctrl)group.There were 6 repetitions in each group.Cell proliferation,apoptosis,lactate dehydrogenase(LDH)activity,mitochondrial membrane potential,lncRNA SNHG12 and miR-140-3p expression levels,and the interaction of lncRNA SNHG12 and miR-140-3p were detected.Results Compared with the control group,the survival rate of HCN,mitochondrial membrane potential,and lncRNA SNHG12 expression were lower in the OGD/R group,while the LDH activity,apoptosis rate,and miR-140-3p expression were higher(P＜0.05).Compared with the OGD/R group and NC group,the survival rate of HCN,mitochondrial membrane potential,and lncRNA SNHG12 expression were higher in the SNHG12 group,while the LDH activity,apoptosis rate,and miR-140-3p expression were lower(P＜0.05).Compared with the SNHG12+miR-NC group,the survival rate of HCN,mitochondrial membrane potential,and lncRNA SNHG12 expression were lower in the SNHG12+miR-140-3p mimics group,while the LDH activity,apoptosis rate,and miR-140-3p expression were higher(P＜0.05).Dual luciferase activity showed a targeted relationship between lncRNA SNHG12 and miR-140-3p(P＜0.05).Conclusion LncRNA SNHG12 may exert a protective effect against OGD/R-induced neuronal damage by inhibiting miR-140-3p.
