Objective To observe the clinical efficacy of Xiaoyu Sanjie Prescription,which is derived from classical prescriptions Chaihu Guizhi Ganjiang Tang and Huoluo Xiaoling Dan,in treating middle-risk lung nodules of phlegm blended with blood stasis type.Methods A total of 104 cases of patients with middle-risk lung nodules of phlegm blended with blood stasis type who met the inclusion criteria were randomly divided into the trial group and the control group,with 52 cases in each group.Eventually,a total of 97 cases completed the trial for epidemic outbreak,of which 48 cases were in the trial group and 49 cases were in the control group.Both groups received health training,and then the control group was only given regular follow-up,while the trial group was treated with Xiaoyu Sanjie Prescription orally.The course of treatment covered three months.The changes in traditional Chinese medicine(TCM)syndrome scores and the area of maximum lung nodule of patients in the two groups before and after treatment were observed.After treatment,overall TCM syndrome efficacy and overall western medicine efficacy as well as their efficacies for various nodules types in the two groups were assessed.Results(1)After treatment,the distribution of the grade of TCM syndrome scores in the trial group was improved significantly when compared with that before treatment(P<0.01),while that in the control group showed no significant improvement(P>0.05),and the intergroup comparison after treatment showed that the improvement in the trial group was significantly superior to that in the control group(P<0.01).(2)The total effective rate of overall TCM syndrome efficacy in the trial group was 81.25%(39/48),and that in the control group was 20.41%(10/49);the intergroup comparison(tested by rank sum test)showed that the overall TCM syndrome efficacy in the trial group was significantly superior to that in the control group(P<0.01).In terms of the efficacy for various nodule types,the trial group had stronger TCM syndrome efficacy for multiple nodules,mixed solid nodules,pure ground glass nodules and solid nodules than the control group,in particular the efficacy for multiple nodules and mixed solid nodules,and the differences were all statistically significant(P<0.05 or P<0.01).(3)After treatment,the area of the maximum lung nodule in the trial group was significantly reduced(P<0.01),whereas there was no significant reduction in the control group compared with that before treatment(P>0.05).Statistically significant difference was shown in the post-treatment area between the two groups and in the pre-and post-treatment difference of the area between the two groups(P<0.05 or P<0.01),which suggested that the trial group's effect on the reduction of maximum lung nodule area was significantly superior to that of the control group.(4)With regard to the efficacy of western medicine,on the whole,the total effective rate of overall western medicine efficacy in the trial group was 45.83%(22/48),while that in the control group was 6.12%(3/49),and the intergroup comparison(tested by rank sum test)showed that the overall western medicine efficacy in the trial group was significantly superior to that in the control group(P<0.01).The western medicine efficacy for multiple nodules in the trial group was superior to that in the control group(P<0.01),while no statistically significant difference was presented in western medicine efficacy for mixed solid nodules,solid nodules,and pure ground glass nodules between the two groups(P>0.05).Conclusion Xiaoyu Sanjie Prescription is effective on relieving the clinical symptoms of patients with middle-risk lung nodules of phlegm blended with blood stasis type,and is effective on stabilizing,reducing or even eliminating some of the lung nodules.The compatibility principle of the formula deserves further discussion.

Chronic cerebral hypoperfusion leads to white matter injury (WMI), which plays a significant role in contributing to vascular cognitive impairment. While 13-docosenamide is a type of fatty acid amide, it remains unclear whether it has therapeutic effects on chronic cerebral hypoperfusion. In this study, we conducted bilateral common carotid artery stenosis (BCAS) surgery to simulate chronic cerebral hypoperfusion-induced WMI and cognitive impairment. Our findings showed that 13-docosenamide alleviates WMI and cognitive impairment in BCAS mice. Mechanistically, 13-docosenamide specifically binds to cannabinoid receptor 1 (CNR1) in oligodendrocyte precursor cells (OPCs). This interaction results in an upregulation of ubiquitin-specific peptidase 33 (USP33)-mediated CNR1 deubiquitination, subsequently increasing CNR1 protein expression, activating the phosphorylation of the AKT/mTOR pathway, and promoting the differentiation of OPCs. In conclusion, our study suggests that 13-docosenamide can ameliorate chronic cerebral hypoperfusion-induced WMI and cognitive impairment by enhancing OPC differentiation and could serve as a potential therapeutic drug.

Objective To investigate the mechanism by which Huangqi Guizhi Wuwu decoction(HQGZWWD)regulates nerve injury(NI)through vascular endothelial growth factor(VEGF)pathway based on a combination of network pharmacology and molecular docking techniques.Methods Active ingredients and targets of HQGZWWD were identified through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.A drug-ingredient-target network was constructed by integrated with data from OMIM,GeneCards,and CTD databases to identify VEGF/NI-related targets.Protein-protein interaction analyses were conducted by using STRING network platform,which were further analyzed by using the DAVID database for Gene Ontology/Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment.A"compound-target-pathway"network was constructed by using Cytoscape.Molecular docking was performed to validate the binding ability of core components with the targets.Results The primary constituents(quercetin,kaempferol)and principal targets[signal transducer and activator of transcription 3(STAT3),caspase 3,epidermal growth factor receptor(EGFR),etc.]of HQGZWWD were identified.KEGG analysis revealed that the targets were enriched cancer,EGFR inhibitor resistance,and advanced glycation end-products-receptor for advanced glycation end-products etc.signaling pathways.Molecular docking demonstrated binding energy between core components and STAT3,caspace 3,EGFR,etc.,specifically,the core components exhibited strong binding energy such as STAT3(≤-7.37kcal/mol).Conclusion HQGZWWD shows potency in suppressing inflammation,oxidative stress,and apoptosis,while promoting neural repair through VEGF regulation.The integration of network pharmacology and molecular docking offers a foundational framework for mechanistic investigations.

Objective:To retrospectively analyze the efficacy and safety of different radiotherapy doses in treating esophageal squamous carcinoma(ESCC)patients aged ≥80 years.Methods:This retrospective study collected clinical data from ESCC patients aged ≥80 years who underwent radiotherapy at the Fourth Hospital of Hebei Medical University from January 2016 to September 2021.Observation variables included overall survival(OS), progression free survival(PFS), complete response(CR), partial response(PR), stable disease(SD), progressive disease(PD), and adverse reactions.Survival rates were estimated using the Kaplan-Meier method and compared via log-rank tests.Cox regression models were employed for multivariate analysis.Results:A total of 165 patients who met the enrollment criteria were included in this study, including 88(88/165, 53.3%)males and 77(77/165, 46.7%)females, age 80 to 100 years(median age 83 years), 66 cases(66/165, 40.0%)in the radiotherapy dose ≥60 Gy group and 99 cases(99/165, 60.0%)in the <60 Gy group.Of the 165 patients, the effective rate was 71.5%(118/165).The median overall survival(OS)of the whole group was 19.0 months, The median Progression Free Survival(PFS)for the whole group was 13 months.The results showed that radiotherapy dose, lesion length, Nutritional Risk Index(NRI), eating condition, recurrence/progression and chemotherapy were factors influencing OS.The survival of patients in the ≥60 Gy group, ≤5 cm group, well-nourished group(NRI ≥45)group, soft diet and general diet group and combined chemotherapy group is better.Cox multivariate analysis revealed that radiotherapy, dose eating condition and the lesion length were independent prognostic factors for OS.The OS rate of the radiation therapy group with a dose of ≥ 60 Gy was better than that of the<60 Gy group( P=0.001), the OS of the general or soft diet group was better than that of the semi liquid or liquid diet group( P=0.008), and the OS of the lesion length ≤ 5 cm group was better than that of the>5 cm group( P=0.020).The incidence rates of radiation-induced esophagitis, myelosuppression, radiation pneumonia, and gastrointestinal reactions in the entire group were 60.0%(99/165), 12.1%(20/165), 22.4%(37/165), and 14.5%(24/165), respectively.51.5%(85/165)of the group experienced local recurrence, 10.3%(17/165)had distant organ metastasis, and 9.1%(15/165)had non regional lymph node metastasis.As of the follow-up date, there were a total of 99 deaths in the entire group. Conclusions:For patients aged 80 years or older with esophageal cancer, higher radiation doses, better feeding and nutritional status have more beneficial for prolonged survival.Local recurrence remains the main reason for treatment failure in elderly patients with esophageal cancer.

Objective The aim of this study is to discuss the causal relationship between periodontal disease(PD)and prostate cancer(PCa).Methods A two-sample bidirectional Mendelian randomization(MR)analysis based on publicly statistical data from genome-wide association studies(GWAS)was conducted.MR Egger,weighted medium,simple mode and weighted mode were supplemented,while inverse variance weighted analysis(IVW)was the main method of analysis.Heterogeneity testing,pleiotropy testing and leave-one-out testing were used to assess the sensitivity and stabili-ty.Results The results of MR analysis showed that PD had no significant impact on the occurrence of PCa:East Asian(IVW,PD:OR=1.07,P=0.48);European(IVW,PD:OR=1.00,P=0.37,periodontitis:OR=1.03,P=0.14,chronic gingivitis:OR=0.99,P=0.37,chronic periodontitis:OR=1.03,P=0.22).The reverse MR analysis also did not show a causal relationship between PCa and PD:East Asian(IVW,PD:OR=0.97,P=0.22);European(IVW,PD:OR=0.84,P=0.44,periodontitis:OR=1.01,P=0.75,chronic gingivitis:OR=0.93,P=0.23,chronic periodontitis:OR=0.99,P=0.80).The results of other analysis were consistent with those of IVW analysis.Conclusions The results of our two-sample bidirectional MR analysis do not support a causal relationship between PD and PCa.

Objective To investigate the impact of various health education intervention strategies on the proper use of personal respiratory protective equipment (RPE) among workers exposed to dust. Methods Dust-exposed workers were recruited from 60 selected enterprises in Guangdong Province using cluster random sampling method. They were randomly allocated to the control, low-intensity intervention, and high-intensity intervention groups, with 358, 346, and 371 workers in each group, respectively. Workers in the control group received no designed intervention. Workers in the low-intensity intervention group received traditional plus mobile health education on the proper use of RPE. Workers in the high-intensity intervention group received all components of the low-intensity intervention, supplemented with peer education. The intervention lasted for six months. RPE usage was compared among the three groups of workers before and after the intervention. Results Workers in the control, low-intensity intervention, and high-intensity intervention groups showed higher rates of both RPE wearing and correct RPE wearing after the intervention than before it within their respective groups (RPE wearing rate: 94.1% vs 99.2%, 95.7% vs 100.0%, 94.6% vs 100.0%, all P<0.01; correct RPE wearing rate: 66.8% vs 91.1%, 67.3% vs 95.7%, 66.6% vs 96.5%, all P<0.01). Post-intervention correct RPE wearing rates were highest in the high-intensity intervention group, followed by the low-intensity intervention group, and the control group, with the percentage of 96.50%, 95.66% and 91.06%, respectively (P<0.01). Binary logistic regression analysis result showed that different intervention strategies affected the correct use of personal RPE among dust-exposed workers after adjusting for gender, age, and other confounding factors (P<0.05). Compared with the control group, the rates of correct RPE use increased in the low-intensity intervention group and the high-intensity intervention group (odd ratio was 2.14 and 3.01; 95% confidence interval was 1.12 - 4.10 and 1.53 - 5.91, respectively). Conclusion The implementation of traditional plus mobile health education interventions on the proper use of RPE can promote correct RPE utilization among dust-exposed workers, and integrating peer education further enhances the intervention effectiveness.

With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.
