Lung cancer is a leading cause of cancer-related morbidity and mortality worldwide. Coupled with the substantial workload, the clinical management of lung cancer is challenged by the critical need to efficiently and accurately process increasingly complex medical information. In recent years, large language models (LLMs) technology has undergone explosive development, demonstrating unique advantages in handling complex medical data by leveraging its powerful natural language processing capabilities, and its application value in the field of lung cancer diagnosis and treatment is continuously increasing. The paper systematically analyzes that the exceptional potential of LLMs in lung cancer auxiliary diagnosis, tumor feature extraction, automatic staging, progression/outcome analysis, treatment recommendations, medical documentation generation, and patient education. However, they face critical technical and ethical challenges including inconsistent performance in complex integrated decision-making (e.g., TNM staging, personalized treatment suggestions) and "black box" opacity issues, along with dilemmas such as training data biases, model hallucinations, data privacy concerns, and cross-lingual adaptation challenges ("data colonization"). Future directions should prioritize constructing high-quality multimodal corpora specific to lung cancer, developing interpretable and compliant specialized models, and achieving seamless integration with existing clinical workflows. Through dual drivers of technological innovation and ethical standardization, LLMs should be prudently advanced for holistic lung cancer management processes, ultimately promoting efficient, standardized, and personalized diagnosis and treatment practices.

Gliomas are the most common primary neuroepithelial tumors of the central nervous system in adults, of which glioblastoma is the deadliest subtype. Apart from the intrinsically indestructible characteristics of glioma (stem) cells, accumulating evidence suggests that the tumor microenvironment also plays a vital role in the refractoriness of glioblastoma. The primary functions of platelets are to stop bleeding and regulate thrombosis under physiological conditions. Furthermore, platelets are also active elements that participate in a variety of processes of tumor development, including tumor growth, invasion, and chemoresistance. Glioma cells recruit and activate resting platelets to become tumor-educated platelets (TEPs), which in turn can promote the proliferation, invasion, stemness, and chemoresistance of glioma cells. TEPs can be used to obtain genetic information about gliomas, which is helpful for early diagnosis and monitoring of therapeutic effects. Platelet membranes are intriguing biomimetic materials for developing efficacious drug carriers to enhance antiglioma activity. Herein, we review the recent research referring to the contribution of platelets to the malignant characteristics of gliomas and focusing on the molecular mechanisms mediating the interaction between TEPs and glioma (stem) cells, as well as present the challenges and opportunities in targeting platelets for glioma therapy.

Immunotherapy, including immune checkpoint inhibitors, tumor vaccine therapy, oncolytic virotherapy, and adoptive cell therapy, has made remarkably breakthroughs in the field of oncology. Immune checkpoint inhibitors, which block programmed death receptor 1 or programmed death ligand 1, have been included in the first-line clinical treatment for advanced solid tumors, such as non-small cell lung cancer and malignant melanoma. However, primary or secondary drug resistance in tumors severely limits the survival benefits for patients. Immune-related adverse reactions, such as pneumonia, hypothyroidism, hypophysitis, and myocarditis, also greatly affect the quality of life of patients. Fuzheng Jiedu Huayu is an important concept guiding the prevention and treatment of tumors with traditional Chinese medicine (TCM). It is also a curative principle and therapeutic TCM method to reduce the toxicity and enhance the efficacy of immunotherapy. This article summarizes the research progress of immunotherapy and discusses how TCM reduces the toxicity and enhances the efficacy of immunotherapy, hoping to provide a reference for the integrated treatment of tumors with TCM and immunotherapy.

Objective To explore the characteritics of spontaneous brain functional activities for patients with hand dysfunction after ischemic stroke using resting state functional magnetic resonance imaging(rs-fMRI).Methods From August,2024 to June,2025,23 patients with hand dysfunction after ischemic stroke were as patients group,and ten age-matched healthy adults were recruited as healthy control group.The patients group was as-sessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Wolf Motor Function Test(WMFT)and modified Lindmark Scale.All subjects underwent rs-fMRI examinations,and the amplitude of low frequency fluctuations(ALFF),fractional amplitude of low frequency fluctuations(fALFF)and regional homogeneity(Re-Ho)were compared between two groups.The resting state functional network was constructed based on indepen-dent component analysis,and the functional connectivity(FC)were analyzed.The rs-fMRI indicators of the pa-tients and the clinical scale scores were analyzed.Results Compared with the healthy control group,the zALFF value decreased in the precentral gyrus(P<0.05,FWE corrected)in the patient group,as well as the values of zfALFF in Cerebelum-Crus2-R(P<0.05,FWE correct-ed),and ReHo values in the putamen(P<0.05,corrected by Alpha Sim).FC of the inferior frontal gyrus(IF-Goperc.R)in the executive control network enhanced(P<0.05,Alpha Sim corrected),while FC of the middle oc-cipital gyrus(MOG.L)in the dorsal attention network(DAN)weakened(P<0.05,Alpha Sim corrected).There was a positive correlation between FC of MOG.L in the patient's DAN and the scores of FMA-UE(r=0.439,P=0.036),WMFT(r=0.516,P=0.012),and modified Lindmark Scales(r=0.425,P=0.043).Conclusion The resting state spontaneous activity of some brain areas of the cerebrum,cerebellum and basal ganglia is reduced in patients with hand dysfunction after ischemic stroke,and some brain network connections are abnor-mal.FC of MOG.L may serve as an objective imaging marker for evaluating hand dysfunction.

Objective:To investigate the effect of age factor on glymphatic function in patients with Parkinson′s disease (PD) and its potential correlation with overall cognitive performance based on diffusion tensor imaging analysis along the perivascular space(DTI-ALPS) index.Methods:The study was cross-sectional. Clinical and imaging data of 77 PD patients (PD group) who attended the Provincial Hospital of Shandong First Medical University from October 2021 to June 2024 were retrospectively analyzed. In the same period, 30 healthy volunteers matched by age and gender were collected as the normal control (NC) group. All subjects underwent MRI scanning and DTI-ALPS index was calculated based on diffusion tensor imaging. Cognitive functions of 46 patients in the PD group were assessed using the mini-mental state examination (MMSE) and montreal cognitive assessment (MoCA) scores. Independent samples t-tests were used to compare the differences in DTI-ALPS index between the PD and NC groups. After adjusting for confounders, the relationship between DTI-ALPS and age was explored using partial correlation analyses, multiple linear regression models. A mediation model was further developed to explore the mediating effect of DTI-ALPS index between age and cognitive function scores. Results:The DTI-ALPS indices of PD and NC groups were 1.66±0.20 and 1.44±0.17, respectively, and the differences were statistically significant ( t=5.27, P<0.001). The age of patients in the PD group was negatively correlated with the DTI-ALPS index ( r=-0.54, P<0.001), and age (β=-0.467, P<0.001) was an independent influencer of DTI-ALPS index. The DTI-ALPS index was positively correlated with MMSE scores ( r=0.53, P<0.001) and positively correlated with MoCA scores ( r=0.56, P<0.001). The mediation model showed that the DTI-ALPS index fully mediated between age and MMSE scores and partially mediated between age and MoCA scores, with an effect share of 33.25%. Conclusion:Age is an independent risk factor for impaired glymphatic pathway in PD patients, and it may induce cognitive decline in PD patients by exacerbating glymphatic pathway impairment.

Objective:To explore brain MRI features of methylmalonic acidemia (MMA).Methods:This observational study retrospectively analyzed the clinical and imaging data of 123 patients with MMA diagnosed at Shandong Provincial Hospital Affiliated to Shandong First Medical University and Qilu Hospital of Shandong University from January 2010 to November 2022. The 123 patients were divided into 7 stages according to age of onset, neonatal period (0 to<1 month), infancy (1 month to<1 year), early childhood (1 to<4 years), preschool (4 to<7 years), school age (7 to<13 years), adolescent (13 to 17 years) and adult (>17 years). All patients underwent brain MRI scanning. The imaging performances were evaluated, including the number, location, morphology of the lesions.Results:Of the 123 patients, 40 were in the neonatal period, 29 in infancy, 13 in early childhood, 9 in preschool, 6 in school age, 13 in adolescence, and 13 in adulthood. The first symptoms of patients in the neonatal period were mainly digestive system abnormalities, such as difficulty in breastfeeding (37.5%, 15/40) and vomiting (25.0%, 10/40), with neurological symptoms gradually becoming the main manifestations from infancy. Seventy-three cases (59.3%) showed significant abnormalities on cranial MRI, including 17 cases with 33 foci in the neonatal period, 23 cases with 53 foci in infancy, 11 cases with 16 foci in early childhood, 2 cases with 2 foci in preschool, 3 cases with 7 foci in school age, 7 cases with 9 foci in adolescence, and 10 cases with 16 foci in adulthood. In neonatal period, the main manifestations were myelin dysplasia (18%,6/33), dilatation of the lateral ventricular system (18%,6/33), and pallidal bulb infarct foci (18%,6/33); in infancy, the main manifestations were hypoplasia or thinning of the corpus callosum (30%,16/53); in early childhood, the main manifestations were pallidal bulb infarct foci (38%,6/16); and the two MRI abnormalities in preschool were pallidum and thalamic infarct foci; in school age, the main manifestations were infarct foci in the chiasmatic nucleus (29%,2/7) and in the caudate nucleus (29%,2/7); in adolescence, the main manifestation was dilatation of the lateral ventricular system (33%,3/9); and in adulthood, the main manifestation was dilatation of the lateral ventricular system (19%,3/16).Conclusion:By staging the age of onset, it is found that the imaging manifestations of MMA patients show significant differences with age, suggesting that there is a dynamic nature of MMA damage to brain structures at different developmental stages.

Esophageal squamous cell carcinoma(ESCC)is a common malignant tumor with insidious early symptoms and a poor prognosis.In traditional Chinese medicine(TCM),ESCC is classified as"ye ge."Drawing on clinical experience,we believe that kidney deficiency leads to the deficiency of vital qi and immune dysfunction,providing the foundation for cancerous growth by depleting qi and damaging essence,toxic stasis and stagnation,forming a local hypoxic and acidic microenvironment that promotes tumor invasion,metastasis,and recurrence.Considering the effect of modern comprehensive treatments,the occurrence and development of ESCC are summarized as kidney deficiency being the root cause and toxic stasis being the driving force.The pathogenesis and treatment of ESCC in the preoperative,postoperative,and non-surgical treatment stages are discussed.The pathogenesis of the disease is summarized as follows:preoperatively,toxicity and stasis intertwine,depleting the kidney;postoperatively,the kidney loses its vitality,allowing various pathogenic factors to persist;during non-operative treatment,vital qi and pathogens contend,resulting in entrenched toxicity.During the preoperative neoadjuvant phase,therapy should resolve stasis,eliminate toxins,enhance kidney function,tonify essence,and support the body.During the postoperative adjuvant phase,therapy should strengthen the root and consolidate the foundation while detoxifying and expelling stasis.The non-surgical treatment stage uses"balanced interruption,"targeting tumor progression and metastasis by harmonizing yin and yang,thus preventing recurrence.This article will provide insights into the integrative Chinese-Western management of ESCC.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Depression is a psychological disorder that imposes a tremendous social burden, with a high prevalence in China. In recent years, the number of diagnosed cases of depression in China has steadily increased, yet the recognition rate of the disease remains low. Depression demostrates a clear familial aggregation pattern. To improve its recognition, numberous studies have utilized the polygenic risk score for major depressive disorder (MDD-PRS) as a potential genetic marker to identify high-risk populations. This article reviews the latest progress and research on the use of MDD-PRS in depression, aiming to clarify its capacity to capture genetic variations associated with depression, its interaction with environmental factors, and their relationship to the onset of the disorder. Additionally, this review evaluates the predictive performance of existing risk models for depression and proposes potential directions for future research.

Coronavirus disease 2019(COVID-19)is a respiratory syndrome caused by severe acute respiratory syn-drome coronavirus 2(SARS-CoV-2).Once SARS-CoV-2 was detected in Wuhan(Hubei Province,China),it rap-idly spread widely across China and the world,posing a serious threat to global health and the economy.With the development of Artificial Intelligence(AI)technology and the openness and application of open-source software,tremendous progress has been achieved in the quantitative study of chest radiology for COVID-19,enabling the quantitative dataization of radiological image data,which adds a powerful indicator to the prognosis study of COV-ID-19.Therefore,we reviewed the current literature on the factors predicting the severity and prognosis of COV-ID-19,and summarized demographic,laboratory and radiological factors to help with risk stratification and prog-nosis assessment for COVID-19 patients and assist in their clinical management and treatment.
