With the widespread application of low-dose computed tomography (CT), the detection rate of multiple lung cancers (MLCs) is gradually increasing. The diagnosis and treatment of MLCs have become a major challenge in clinical practice in thoracic surgery and oncology. In April 2025, the Lung Cancer Professional Committee of the China Anti-Cancer Association (CACA) organized multidisciplinary experts from both domestic and international fields to release the first edition of the CACA Expert Consensus on the Diagnosis and Treatment of Multiple Lung Cancers, providing systematic recommendations for the diagnostic system, molecularassessment strategies, and surgical and non-surgical management of MLCs. This article provides a detailed interpretation of the core content of this consensus and, by incorporating the latest research progress in the field, delves into the pathogenesis, precise diagnostic strategies, and individualized treatment pathways for multiple lung cancers, aiming to offer a more comprehensive reference for clinical practice.

OBJECTIVE To investigate the clinical efficacy and mechanism of Gongliuxiao capsule combined with dienogest (DNG) in the treatment of refractory/recurrent endometriosis (EMT). METHODS A retrospective analysis was conducted on the clinical data of 94 patients with refractory/recurrent EMT admitted to Qingdao TCM Hospital from January 2022 to January 2025. According to different treatment methods, they were divided into a monotherapy group (47 cases, receiving DNG monotherapy) and a combination group (47 cases, receiving Gongliuxiao capsule combined with DNG). The cl inical efficacy, symptom and sign scores [Visual Analog Scale (VAS) and Pictorial Blood Loss Assessment Chart (PBAC) scores ] , vascular endothelial function indicators [serum transforming growth factor-β 1 (TGF-β 1 ), vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2), MMP-9, basic fibroblast growth factor (bFGF) ] , serum pathological factors [carbohydrate antigen 125 (CA125), CA199, anti-endometrial antibody (EMAb) ] , and Th1/Th2 drift indicators [interferon-γ (IFN-γ), interleukin-4 (IL-4) ] were compared between the two groups before and after 6 months of treatment. RESULTS After treatment, the VAS and PBAC scores, serum levels of TGF-β 1 , VEGF, MMP-2, MMP-9, bFGF, CA125, CA199, EMAb, and IL-4 in both groups were significantly lower than those before treatment, while IFN-γ levels were significantly higher than those before treatment ( P <0.05). Moreover, the magnitude of increase or decrease in the combination group was significantly greater than that in the monotherapy group ( P <0.05). The total effective rate in the combination group was significantly higher than that in the monotherapy group (93.62% vs. 76.60%, P <0.05). CONCLUSIONS The combination of Gongliuxiao capsule and DNG is effective in treating refractory/recurrent EMT, and can effectively improve the degree of dysmenorrhea and abnormal menstrual volume in patients. The mechanism may be related to improving vascular endothelial function, inhibiting the expression of tumor pathological factors, and correcting Th1/Th2 drift.

Olfactory receptors (ORs) form the largest superfamily of G protein-coupled receptors (GPCRs). Traditionally recognized for their role in the nasal olfactory epithelium, where they mediate the sense of smell, accumulating evidence has firmly established their ectopic expression in non-olfactory tissues, including the intestine, lungs, and kidneys. The intestine, as the primary site for nutrient digestion and absorption, harbors a highly complex chemical environment. To adapt to this environment, the gut employs a sophisticated network of “chemosensors” to monitor luminal contents and maintain homeostasis. Among these sensors, intestinal ORs have emerged as crucial functional components, serving as a molecular bridge that connects environmental chemical signals—such as food-derived odorants—to specific physiological responses. This discovery has significantly deepened our understanding of how dietary flavors and compounds influence intestinal physiology at the molecular level. This review systematically summarizes the expression profiles, ligand classification, and biological functions of ORs within the gastrointestinal tract. Studies indicate that intestinal ORs exhibit distinct spatial distribution patterns across different gut segments and display cell-type specificity, particularly within enterocytes and enteroendocrine cells. These receptors function as versatile sensors capable of recognizing a wide variety of ligands, including exogenous dietary components, gut microbiota metabolites such as short-chain fatty acids, and endogenous small molecules like azelaic acid. Upon activation by specific ligands, intestinal ORs trigger intracellular signaling cascades, primarily involving the AC-cAMP-PKA pathway or calcium influx channels. A major focus of this review is to elucidate the molecular mechanisms by which these receptors regulate the secretion of gut hormones. Activation of specific ORs in enteroendocrine cells has been shown to stimulate the release of hormones such as glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and serotonin (5-HT), thereby modulating systemic energy metabolism, glucose homeostasis, and gastrointestinal motility. Furthermore, the review addresses the critical roles of ORs in immune regulation and pathology. Evidence suggests that specific ORs contribute to the maintenance of intestinal immune homeostasis and may offer protection against inflammation. Beyond their involvement in inflammatory responses, ORs such as Olfr78 have been shown to regulate the differentiation and function of intestinal endocrine cells. Similarly, Olfr544 has been demonstrated to alleviate intestinal inflammation by remodeling the gut microbiome and metabolome. These findings collectively suggest that specific ORs hold promise as therapeutic targets for mitigating intestinal inflammation and maintaining gut homeostasis. Additionally, the review explores the emerging role of ORs in cancer. Although OR expression is often downregulated in tumor tissues compared to normal mucosa, activation of specific ORs by certain ligands can inhibit tumor cell proliferation and migration and induce apoptosis via pathways such as MEK/ERK and p38 MAPK. Conversely, other receptors, such as OR7C1, may serve as biomarkers for cancer-initiating cells. In conclusion, intestinal ORs represent a vital component of the gut’s sensory network. The review also discusses the translational potential of these findings. By elucidating the precise pairing relationships between dietary components and specific ORs, novel therapeutic strategies could be developed. Intestinal ORs may thus emerge as promising targets for nutritional and pharmacological interventions in metabolic diseases, inflammatory bowel diseases, and malignancies.
4.Association between brain and muscle Arnt like protein 1 gene polymorphisms and ambulatory blood pressure among college students
Chinese Journal of School Health 2026;47(6):864-868
Objective:
To investigate the association between brain and muscle Arnt like protein 1( BMAL 1) gene and ambulatory blood pressure (ABP) parameters in college students, and to explore the influence of the interaction between the gene and weight status on the ABP levels, so as to provide reference for early prevention of chronic cardiovascular diseases related to hypertension.
Methods:
During September 2022 to June 2024, a total of 510 college students were recruited from a university in Changsha, China for on site questionnaire investigation, physical examination, ABP monitoring and genotyping testing. Multiple linear regression method was used to explore the association between the BMAL 1 gene and ABP indicators. An interaction term was included in the general linear model of multiple linear regression to analyze the interactive effects of BMAL 1 gene polymorphisms and weight status on ABP levels.
Results:
The prevalence of abnormal 24 hour blood pressure, abnormal daytime blood pressure, and abnormal nighttime blood pressure were 3.3%, 3.1%, and 3.9%, respectively. Multiple linear regression analysis showed that the BMAL 1/rs7950226 polymorphism was positively correlated with the 24 hour diastolic blood pressure(DBP) and the daytime DBP level after adjusting for gender, age, and body mass index( β =0.87,0.99, both P <0.05). Also, interaction between BMAL 1/ rs 11022775 and weight status on the nighttime DBP level ( P interaction =0.03) was found. The CC genotype carriers had significantly higher nighttime DBP level ( β =3.52, P <0.05) among overweight/obesity college students, but no differences in nocturnal DBP levels were observed between CC genotype carriers and TT+CT genotype carriers among college students with normal body weight( P > 0.05).
Conclusions
The rs 7950226 polymorphism is associated with 24 hours DBP and daytime DBP levels. Significant interaction between rs 11022775 with weight status on the nighttime DBP level is found among college students.

Malignant gastrointestinal tumors (GT) mainly include laryngeal cancer, esophageal cancer, gastric cancer, pancreatic cancer, hepatocellular carcinoma, bile duct cancer, and colorectal cancer. At present, the morbidity and mortality of GT are high. Tumor immune escape is one of the key reasons for cancer development and treatment failure, and it is also the main direction of current tumor immunotherapy research. Traditional Chinese medicine (TCM) plays a role in treating GT and alleviating systemic symptoms, especially showing potential advantages in regulating the immune escape mechanism. This article elaborates on the immune escape mechanism of GT and systematically reviews that TCM active components or compound prescriptions act on key immune checkpoints such as programmed cell death protein-1 (PD-1) and programmed cell death ligand-1 (PD-L1) to reduce the proportion of marrow-derived suppressor cells (MDSCs), promote the polarization of M1 macrophages, activate effector immune cells, enhance CD8+ T cell recruitment and interferon (IFN)-γ secretion, enhance the killing activity of natural killers (NKs), and reduce foxhead box protein P3(FoxP3+)-positive regulatory T (Treg) cell infiltration. TCM active components or compound prescriptions can remodel the tumor microenvironment (TME), such as improving immunosuppressive factors, promoting vascular normalization, and regulating intestinal microbiota. Through the regulation of TME, enhancement of antigen presentation, inhibition of immune checkpoint molecules, regulation of cellular network factors and metabolites, etc., TCM active components or compound prescriptions enhance the immune function, thereby inhibiting the immune escape of GT. This paper summarizes and reflects on the research results of TCM in regulating immune escape to treat GT in recent years, aiming to help transform TCM from empirical medication to precision treatment based on immune regulation, reduce drug resistance and enhance treatment effect.

OBJECTIVE To develop and validate interpretable machine learning models for predicting the risk of medication-related osteonecrosis of the jaw (MRONJ) and surgical outcomes, thereby providing quantitative support for MRONJ risk assessment and treatment decision-making.METHODS Two study cohorts were established. Cohort A adopted a nested case-control study design to develop a predictive model for the risk of MRONJ onset. Cohort B comprised patients with MRONJ from Cohort A who underwent surgical treatment and met the follow-up eligibility criteria, and employed a prospective follow-up cohort study design to develop a predictive model for the efficacy of MRONJ surgery. After missing-data processing, variable standardization, and encoding, predictive features were selected using the least absolute shrinkage and selection operator (LASSO) regression, and collinearity was assessed using the variance inflation factor (VIF). Random Forest (RF), eXtreme Gradient Boosting (XGB), Multi-layer Perceptron (MLP), Support Vector Machine (SVM), and Gaussian Naive Bayes (NB) models were subsequently developed using the selected features. Hyperparameter optimization and internal performance evaluation were performed using two-level nested cross-validation repeated 20 times. In Cohort B, the synthetic minority over-sampling technique (SMOTE) was applied within the inner training folds to address class imbalance. Model performance was comprehensively evaluated using the receiver operating characteristic (ROC) curve, the precision-recall (PR) curve, calibration curve, and decision curve analysis (DCA). Shapley additive explanations (SHAP) were used to quantify the relative contributions of individual clinical features to model predictions.RESULTS Seven clinical features, including alkaline phosphatase and tooth extraction, were retained for Cohort A; whereas eight clinical features, including age and duration of medication use, were retained for Cohort B. In Cohort A, the area under the ROC curve, the area under the PR curve, Brier score, sensitivity, and specificity of the RF model were 0.94, 0.92, 0.09, 0.92, and 0.85, respectively; the corresponding values in Cohort B were 0.93, 0.93, 0.12, 0.83, and 0.93, respectively. The results of calibration curves and DCA indicated that the RF models achieved favorable calibration and clinical net benefit, with VIF values for all variables below 5. SHAP visualization results showed that alkaline phosphatase, tooth extraction, and cumulative drug dose made substantial contributions to MRONJ risk prediction in Cohort A, whereas age, duration of medication use, and MRONJ stage contributed substantially to surgical outcome prediction in Cohort B.CONCLUSIONS The RF-based models for predicting MRONJ risk and surgical outcomes demonstrated good discrimination, accuracy of probabilistic predictions, and potential clinical utility during internal validation. These models may provide decision support for comprehensive MRONJ risk management and individualized clinical decision-making. However, external validation in independent, multicenter, and geographically diverse cohorts is still required.

Widespread utilization of glyphosate has led to environmental residues,posing potential threats to ecological systems and human health.Traditional methods for detection of glyphosate are limited by specialized equipment and operational techniques,resulting in inefficient responses.Therefore,it is urgent to develop a convenient,sensitive and accurate detection method for detection of glyphosate.Herein,a new naphthalenesulfonamide-based"Turn-on"fluorescent probe was synthesized using 2-chloroaniline and dansyl chloride as raw materials through a one-step process,which showed a good linear relationship between the glyphosate concentration in concentration range of 0.003-70 μmol/L and the fluorescence intensity(R2=0.995),with a detection limit of 2.73 nmol/L(S/N=3).Analytical techniques such as nuclear magnetic resonance(NMR)spectroscopy and high-resolution mass spectrometry(HRMS)were used to investigate the interaction mechanism between the fluorescent probe and glyphosate.The results indicated that a nucleophilic substitution reaction occurred between the probe and the secondary amine(—NH—)of glyphosate,inducing a photoinduced electron transfer(PET)effect which enhanced the fluorescence intensity by 11.2 times.The probe showed good anti-interference ability towards coexisting metal ions,anions and pesticides in water.When applied to determination of glyphosate in the samples such as tap water,river water(Xiangxi River Reservoir),soil,soybeans,and corn,the spiking recoveries ranged from 94.7%to 109.9%,demonstrating the high accuracy and broad applicability of this detection method.A portable test strip based on this fluorescent probe was developed for rapid semi-quantitative analysis of glyphosate.The developed method was rapid,sensitive,and portable,providing theoretical and technical support for on-site measurement of environmental contaminants.

In the 1950s and 1960s,Japan's implementation of policies prioritizing economic develop-ment caused a lack of effective supervision over the discharge of industrial wastewater and exhaust gases,which led to the occurrence of the"Four Major Pollution Diseases",including Minamata disease,causing serious social and public health problems.To more effectively address public nuisances and pro-vide compensation to victims,the Japanese government gradually established an environmental damage compensation system with administrative relief characteristics since the 1970s.Through long-term prac-tice and system optimization,this system has evolved into a mature institutional framework with a clear division of labor and efficient collaboration.This paper systematically reviews the development process of Japan's environmental damage compensation system and deeply analyzes its legal frame-work and supporting policies,aiming to provide useful references for the construction and improve-ment of China's environmental damage compensation system.Meanwhile,through the case analysis of Minamata disease,the paper explores the specific mechanisms and effects in the compensation practices,further revealing the system's operational characteristics and implications,and providing a reference ba-sis for the construction of China's environmental governance legal system.
