Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.

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.

Objective:
The cross sectional study aimed to identify predominant co-occurrence patterns among six common mental health issues in college students, so as to provide empirical basis for designing targeted interventions.
Methods:
From October 2024, a total of 9 837 students from 4 universities in Xiangtan City, Hunan Province, participated in the current study by multistage random cluster sampling method. Participants completed self report measures, including the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7 item Scale (GAD-7), Young s Internet Addiction Diagnostic Questionnaire, the Adolescent Insomnia Symptom Self rating Scale, the Ottawa Self injury Inventory, and the Brief Community Assessment of Psychic Experiences Questionnaire. Demographic and co-occurrence characteristics were first compared using Chi square or trend Chi-square tests, followed by application of the Apriori algorithm to mine association rules for primary co-occurrence patterns.
Results:
The detection rate of co-occuring the common mental health issues was 46.44%. The detection rate was significantly higher in female than in male students (50.42%, 43.61%; χ 2=44.46) and in students from rural versus urban areas (47.22%, 44.60%; χ 2=5.67) (both P <0.05). Significant differences were observed among freshmen, sophomores, juniors, and seniors (46.63%, 48.35%, 45.05% , 43.66%, respectively; χ 2=9.22, P <0.05), although no statistically significant trend was detected ( χ 2 trend =3.75, P = 0.05 ). Association rule mining identified “anxiety + depression” “anxiety + psychotic experiences + depression” and “anxiety + sleep disorder + depression” as the combinations with the highest support. In addition, “anxiety+depression+Internet addiction+psychotic experiences =>sleep disorder (>= refered to the occurrence of the latter item under the condition that the former item occurs)” and “anxiety + depression+Internet addiction=>sleep disorder” were combinations with relatively high confidence.
Conclusions
Co-occurrence of these mental health issues among college students is high and exhibits diverse patterns. Strategies to address this burden should prioritize integrated interventions that target these specific combinations of factors.

Ischemia-reperfusion injury of solid organs is a common complication during transplantation, but its mechanism remains unclear and there are no effective prevention and treatment methods. Rejection is a common immune response of the graft, which is classified into hyperacute rejection, acute rejection and chronic rejection. Rejection and ischemia-reperfusion injury of solid organs may share some common mechanisms, and further research on their correlation may provide strategies for the prevention and treatment of ischemia-reperfusion injury of solid organs. This article mainly reviews the association between rejection and ischemia-reperfusion injury of solid organs.

ObjectiveCell adhesion is a critical process that regulates cellular physiological functions. Quantitative characterization of adhesion dynamics is essential for elucidating the intrinsic mechanical mechanisms underlying cellular activities. Although atomic force microscopy-based single-cell force spectroscopy is widely used for single-cell adhesion measurements, it requires complex chemical modifications for preparation of live-cell probes, leading to limitations such as cumbersome operation, low throughput, and potential impacts on cell viability. Fluidic force microscopy, which combines atomic force microscopy with microfluidic probes, is a technique allowing the operation of force-controlled nanopipettes in aqueous environments. By applying negative or positive pressure via a pressure controller, a single living cell can be captured onto or released from the cantilever under physiological conditions. This procedure offers a simple workflow and high assay throughput for single-cell adhesion measurements without the need for chemical functionalization. In this study, fluidic force microscopy-based single-cell force spectroscopy was adopted to achieve long-term quantitative characterization of single-cell adhesion dynamics in a simpler and more efficient manner, comparing the dynamic differences in adhesion establishment between two cell lines with different differentiation levels. MethodsHEK 293T and hTERT RPE-1 cells were non-invasively captured on the cantilever of a fluidic force microscope via its integrated microfluidic system during 40 h of adhesion culture. Cell-substrate detachment assays were performed, and force-distance curves were recorded to extract key mechanical adhesion parameters, including adhesion force, adhesion energy, and maximum detachment distance. These measurements were combined with real-time monitoring of cell spreading area to systematically characterize the dynamic evolution of single-cell adhesion. ResultshTERT RPE-1 cells rapidly entered a stable adhesion phase within 1 h after seeding, with both area-normalized adhesion force and area-normalized adhesion energy reaching peak values. In contrast, HEK 293T cells required 4 h to achieve stable adhesion. Subsequently, the adhesion force, adhesion energy and maximum detachment distance of hTERT RPE-1 and HEK 293T cells stabilized at approximately 240 nN vs. 30 nN, 2.2 pJ vs. 0.12 pJ and 6 μm vs. 4 μm, respectively. hTERT RPE-1 cells reached the peak of area-normalized adhesion parameters earlier than HEK 293T cells, with their peak area-normalized adhesion force and area-normalized adhesion energy being substantially elevated relative to HEK 293T cells. HEK 293T cells presented stronger linear correlations among adhesion energy, maximum detachment distance and adhesion force compared with hTERT RPE-1 cells. For both cell lines, cell spreading area exhibited a weak correlation with adhesion force. Whereas the area-normalized adhesion parameters of HEK 293T cells remained relatively constant throughout the adhesion process, hTERT RPE-1 cells exhibited elevated values in the early phase, followed by a gradual decline. These results indicated distinct dynamic adhesion patterns between the two cell types, with hTERT RPE-1 cells exhibiting stronger adhesion strength and higher adhesion efficiency. ConclusionIn this study, fluidic force microscopy-based single-cell force spectroscopy was successfully applied to perform long-term in situ quantitative measurement of the adhesion dynamics in single adherent cells. The approach revealed divergent adhesion patterns between HEK 293T and hTERT RPE-1 cells, suggesting a close association between cell differentiation and adhesion behaviors. These findings provide quantitative mechanical evidence for further understanding the underlying mechanisms of cell adhesion.

ObjectiveTo explore the establishment of a rat model of diabetic macrovascular atherosclerosis (DMA) with Qi and Yin deficiency syndrome induced by high-fat diet, streptozotocin (STZ), and Yin-depleting herbs, and to evaluate its biological characteristics. MethodsForty SD rats were randomly divided into a blank group (n=10) and a modeling group (n=30). Except for the blank group, rats in the model group were fed a high-fat diet for 4 weeks, followed by intraperitoneal injection of STZ (30 mg·kg-1) to establish a diabetic model. Twenty-four successfully modeled diabetic rats were randomly divided into a model group (n=7), a Qi and Yin deficiency syndrome group (n=8), and a counter-syndrome group (n=9). Except for the model group, rats received intragastric administration of Yin-depleting herbs (1.2 g·kg-1) for 8 weeks. The counter-syndrome group was further treated with Shenqi compound formula (1.69 g·kg-1) for an additional 8 weeks. General condition and body weight were recorded, and syndrome-related indicators were assessed, including precordial temperature, skin moisture content, grip strength, open-field test performance, and tongue appearance. Serum levels of vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), vascular cell adhesion molecule-1 (VCAM-1), insulin-like growth factor-1 (IGF-1), and monocyte chemotactic protein-1 (MCP-1) were measured by enzyme-linked immunosorbent assay (ELISA). Fasting blood glucose, blood lipids, hemorheological parameters, and coagulation function were analyzed using an automatic biochemical analyzer. Vascular ultrasound and hematoxylin-eosin (HE) staining were used to evaluate vascular lesions. ResultsIn terms of syndrome manifestations, compared with the blank group, body weight increased rapidly during the first 5 weeks in the model, Qi and Yin deficiency, and counter-syndrome groups. After STZ injection combined with Yin-depleting herbal administration at week 5, body weight decreased significantly (P<0.01) and continued to decline until the end of the experiment. Rats exhibited decreased activity, irritability, coarse and yellowish fur with obvious shedding, polydipsia, polyphagia, frequent urination, and dry stools, which were most pronounced in the Qi and Yin deficiency group. Grip strength decreased, peak activity time occurred earlier, total distance in the open-field test was reduced, and residence time was prolonged. Precordial temperature decreased (P<0.01), while paw temperature increased (P<0.05), and skin moisture and oil content were reduced (P<0.05, P<0.01). In terms of disease-related indicators, compared with the blank group, fasting blood glucose was significantly increased (>16.7 mmol·L-1) in the model and Qi and Yin deficiency groups, and blood lipid levels were significantly elevated (P<0.05). Vascular-related factors ET-1, MCP-1, VCAM-1, and VEGF were significantly increased (P<0.05,P<0.01), while IGF-1 was significantly decreased (P<0.01). Pathological examination of the aortic valve showed valvular thickening and structural disorganization. Carotid artery examination revealed discontinuity of the intima, foam cell accumulation beneath the intima, disordered smooth muscle arrangement, and widened intercellular spaces. Compared with the model group, ET-1, MCP-1, and VEGF levels were significantly decreased in both the Qi and Yin deficiency group and the counter-syndrome group. The reductions in ET-1 and MCP-1 were more pronounced in the Qi and Yin deficiency group (P<0.01), while the decrease in VCAM-1 was more significant in the counter-syndrome group (P<0.05). Compared with the blank group, the Qi and Yin deficiency group showed significantly prolonged activated partial thromboplastin time (APTT), thrombin time (TT), and prothrombin time (PT) (P<0.01). The erythrocyte deformability index (TK), erythrocyte sedimentation rate, erythrocyte electrophoresis index, and whole blood low-shear viscosity all showed increasing trends. Vascular ultrasound revealed reduced arterial blood flow velocity, increased vascular resistance, and intimal thickening without plaque formation. The aortic intima showed no obvious overall thickening, with only occasional localized thickening and foam cell presence, and carotid artery injury was observed. ConclusionA rat model of DMA with Qi and Yin deficiency syndrome was successfully established using high-fat diet feeding combined with STZ injection and Yin-depleting herbal administration. Shenqi compound formula effectively alleviated Qi and Yin deficiency syndrome, regulated glucose and lipid metabolism, improved hemorheological and coagulation function, reduced vascular lesion severity, and demonstrated potential for early prevention and treatment of DMA.

ObjectiveTo investigate the mechanism by which Tianxiang pills (TXP) alleviates myocardial cell pyroptosis in the rat model of myocardial ischemia/reperfusion (I/R) injury through modulating the reactive oxygen species (ROS)/cysteinyl aspartate-specific proteinase-1 (Caspase-1)/gasdermin D (GSDMD) signaling pathway. MethodsA total of 54 SPF-grade adult male Sprague-Dawley rats were randomized into six groups (n=9): sham (thoracotomy only without ligation), I/R (left anterior descending coronary artery ligation for 30 min followed by reperfusion), NAC (positive control, N-acetylcysteine, 150 mg·kg-1, by gavage), low-dose Tianxiang pills (TXP-L, 2.5 g·kg-1, by gavage)], medium-dose Tianxiang pills (TXP-M, 5 g·kg-1, by gavage), and high-dose Tianxiang pills (TXP-H, 10 g·kg-1, by gavage). The fluorescent probe method was employed to measure the ROS level. Biochemical assay kits were employed to determine the Caspase-1 activity, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, and glutathione peroxidase (GSH-Px) activity. Myocardial infarct size was assessed by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Western blot analysis was performed to evaluate the expression levels of proteins in the ROS/Caspase-1/GSDMD pathway, including GSDMD, cleaved Caspase-1/Caspase-1 ratio, the N-terminal domain of GSDMD (GSDMD-N), and the p22-phox subunit of the reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. Enzyme-linked immunosorbent assay (ELISA) was utilized to determine the concentration of interleukin-1β (IL-1β). Transmission electron microscopy (TEM) was employed to observe mitochondrial structure and to score the degree of mitochondrial swelling. ResultsCompared with the Sham group, the I/R group exhibited elevated the levels of ROS, Caspase-1 activity, GSDMD expression, IL-1β concentration, MDA content, infarct area, mitochondrial swelling score, cleaved Caspase-1/Caspase-1, GSDMD-N, and p22phox and decreased activities of SOD and GSH-Px (P<0.05). Compared with the I/R group, NAC and different doses of TXP significantly reduced the ROS level, Caspase-1 activity, GSDMD expression, IL-1β concentration, MDA content, infarct area, and mitochondrial swelling score. Moreover, they downregulated the expression of cleaved Caspase-1/Caspase-1, GSDMD-N, and p22phox and increased the activities of SOD and GSH-Px (P<0.05). Furthermore, TXP exerted effects on ROS, MDA, SOD, GSH-Px, Caspase-1 activity, GSDMD expression, IL-1β concentration, cleaved Caspase-1/Caspase-1, GSDMD-N, p22phox, infarct area, and mitochondrial swelling score in a dose-dependent manner (P<0.05). ConclusionTianxiang pills alleviates myocardial I/R injury by mitigating oxidative stress and cell pyroptosis through the inhibition of the ROS/Caspase-1/GSDMD signaling pathway.

Objective: To analyze the characteristics and key risk factors of abnormal blood disposal throughout the 2024-2025 blood collection and supply process based on nationwide multi-site monitoring data, develop a comprehensive prevention and control strategy across the entire chain, reduce preventable blood waste, and ensure clinical blood safety. Methods: According to the Guidelines for Haemovigilance (T/CSBT 001-2026), we extracted 74 cases of abnormal blood disposal events reported by the China Blood Transfusion Association′s Blood Safety Monitoring System from January 1 2024, to December 31 2025, and conducted descriptive statistical analysis on the distribution of events, types of deviations, root causes, and classifications of disposal manifestations. Results: A total of 664 adverse events related to blood collection and supply were reported over two years, with 74 cases involving discarded abnormal blood units, accounting for 11.1% of the total. Among these, blood component preparation (40.5%) and blood collection (37.8%) remained traditional high-risk stages. The proportion of blood waste occurring during storage, distribution, and transportation increased from 7.7% in 2024 to 34.3% in 2025. Deviations from standard operating procedures (SOP) by personnel were the primary cause, accounting for 74.3% of cases. Discarded blood units were categorized into four types: compromised closed blood bag systems (40 cases), mainly due to inadequate heat sealing, physical damage, or dropped bags; blood out of the cold chain (12 cases), primarily resulting from blood being left at work sites; imbalanced proportion of preservation solution (10 cases), mostly caused by blood collection volumes exceeding the standard capacity of blood bags; and other causes (12 cases). Conclusion: Human operational errors are the core cause of abnormal blood waste. The collection and preparation stages have long been at high-risk, and the risks in the storage and transportation stages have been increasing year by year. We should focus on standardizing personnel management, improving specialized operation norms such as heat sealing, transportation, and storage, establishing a full-process intelligent cold chain monitoring and multi-node visual verification mechanism, and systematically reducing the occurrence rate of abnormal blood waste through a closed-loop quality intervention system, thereby improving the utilization efficiency of voluntary blood donation resources.

OBJECTIVE To explore the effect and potential mechanism of 717 Jiedu decoction in ameliorating local tissue injury induced by Gloydius brevicaudus venom via regulating macrophage phenotype transformation.METHODS Rat blank-serum and drug-containing serum were prepared by intragastric administration of normal saline, tail-vein injection of anti- G. brevicaudus venom serum (0.6 mL per rat), and intragastric administration of 717 Jiedu decoction at doses of 0.495, 0.99 and 1.98 g/kg (calculated as crude drug). M0-type macrophages derived from human leukemia monocytic THP-1 cells induced and differentiated by PMA were divided into normal control group, model group, positive control group, and low-, medium- and high-concentration 717 Jiedu decoction drug-containing serum groups. Except for the normal control group, all other groups were treated with 10 μg/mL G. brevicaudus venom working solution and 10% blank or drug-containing serum. After the cultivation period, the cellular ultrastructural changes in each group were observed; the proportions of M1- and M2-type macrophages, as well as the mRNA and protein expression of macrophage phenotype transformation and hypoxia-inducible factor-1α (HIF-1α) were detected.RESULTS Compared with the normal control group, cells in the model group presented ultrastructural injuries including mitochondrial swelling, cristae rupture and cytoplasmic vacuolization. The proportion of M1-type macrophages and the mRNA and protein expression levels of related phenotype transformation markers [inducible nitric oxide synthase, tumor necrosis factor-α, interleukin-6 (IL-6), IL-1β] and HIF-1α were significantly increased ( P <0.05),whereas the proportion of M2-type macrophages and the mRNA and protein expression levels of related phenotype transformation markers (arginase-1, IL-10, mannose receptor C type 1 and chitinase-3-like protein 1) were significantly decreased ( P <0.05). Compared with the model group, cellular ultrastructural injuries were obviously alleviated, and the above-mentioned indexes were significantly reversed in the high-concentration 717 Jiedu decoction drug-containing serum group ( P <0.05).CONCLUSIONS717 Jiedu decoction can exert anti-inflammatory and tissue-repairing effects by regulating the balance of M1-, M2-type macrophages phenotype transformation and repairing cellular ultrastructural damage. Its mechanism may be related to inhibiting the excessive activation of the HIF-1α pathway.

Objective Patients with lung cancer often experience interrelated symptoms such as fatigue, pain, and sleep disturbances during chemotherapy, forming a core symptom cluster that significantly impacts daily functioning, treatment experience, and quality of life. Currently, evidence on non-pharmacological management of this core symptom cluster is scattered, and there is a lack of standardized, patient- and caregiver-friendly guidance tools that are easy to understand and implement. This patient guideline aims to provide decision support for self-management of the core symptom cluster in patients undergoing chemotherapy for lung cancer. Methods Guided by evidence-based methodology, qualitative interviews and on-site questionnaire surveys were conducted to identify the health-related needs of stakeholders. Domestic and international guideline websites, relevant professional association websites, and comprehensive databases were systematically searched according to the inclusion and exclusion criteria. The included literature was evaluated for quality, and recommendations were extracted, integrated, and graded to form a summary of the best evidence. Based on the identified health issues and evidence summary, preliminary recommendations for the patient guideline were developed. The recommendations were then revised through two rounds of Delphi expert consultation, and consensus was reached on the strength of recommendations, forming the final version of the patient guideline. Results The patient guideline covered four major sections: screening and assessment of core symptom clusters, daily management, intervention measures, and timing of referral. The core content included nine aspects: screening of core symptom clusters, assessment, lifestyle habits, dietary interventions, sleep environment, exercise interventions, psychological interventions, Traditional Chinese Medicine interventions, and referral indications. In total, the guidelines addressed 16 health issues and provided 25 recommendations. Conclusion The development process of this patient guideline is rigorous and fully considered the needs of patients. Expert review concludes that the recommendations are highly feasible and appropriate.
