Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective:To investigate the protective effect of myrislignan（MRL）on concanavalin A（Con A）-induced autoimmune hepatitis（AIH）.Methods:C57BL/6J mice were divided into the following groups using a random number table，with five mice in each group：control group，MRL group，model group（Con A group），and MRL pretreatment group（MRL+Con A group）. MRL was injected intraperitoneally at a dose of 30 μg/g；3 h after pretreatment，Con A（18 μg/g）was administrated by intravenous injection；mouse livers and serum samples were collected 12 h after injection for measuring serum transaminase levels and liver cell apoptosis. The mRNA and protein expression levels of IL-6，IL-12，and TNF-α were measured using qRT-PCR and ELISA. Flow cytometry was performed to detect the proportion and activation status of macrophages in liver tissues. Bone marrow-derived macrophages（BMDMs）were isolated and induced in vitro to analyze the regulatory effect of MRL on macrophages. One-way analysis of variance was used to compare the differences in various indicators among groups. Results:Compared with the Con A group，MRL（30 μg/g）pretreatment significantly reduced alanine aminotransferase（ P<0.05）and aspartate transaminase（ P<0.01）levels，attenuated liver oxidative stress（increased superoxide dismutase activity，while decreased levels of malondialdehyde and myeloperoxidase；all P<0.05），and suppressed hepatocyte apoptosis（ P<0.01）. Both in vivo and in vitro experiments confirmed that MRL（30 μg/g）could reduce the proportion of M1 macrophages（ in vivo： P<0.05； in vitro：all P<0.001）and inhibit macrophage activation（ in vivo： P<0.01； in vitro：all P<0.05）. Conclusion:MRL effectively prevents Con A-induced autoimmune hepatitis by inhibiting liver cell apoptosis，attenuating liver oxidative stress，suppressing M1 macrophage polarization，and reducing inflammatory cytokine expression.

Objective:To investigate the clinical efficacy of autologous adipose-derived stem cell gel (SVF-gel) grafting in the treatment of depressed acne scars.Methods:A retrospective analysis was conducted on data collected from 28 patients who underwent SVF-gel grafting treatment for depressed acne scars in the Department of Dermatology, Xijing Hospital, Air Force Medical University from October 2018 to May 2021. There were 17 males and 11 females, aged 17 - 38 (26 ± 4.86) years. As for clinical types, 8 patients were diagnosed with boxcar acne scars, 14 with rolling acne scars, and 6 with acne scars with characteristics of the two types. The clinical acne scar weighted scale (ECCA scale) was used to evaluate the appearance improvement after the treatment, and patients′ subjective satisfaction scores and incidence of adverse reactions were recorded.Results:After the SVF-gel grafting, the facial appearance of patients with depressed acne scars significantly improved, and the ECCA scores significantly decreased 6 months after surgery (before surgery: 52.5 ± 15.8 points; 6 months after surgery: 23.8 ± 10.2 points; t = 11.68, P < 0.001). The subjective satisfaction rate of patients was 82.14% (23/28), the incidence rate of adverse reactions was 17.86% (5/28), and 5 patients experienced mild inflammatory reactions after surgery, including 2 with subcutaneous nodules. The secondary grafting rate was 67.86% (19/28) . Conclusion:The SVF-gel grafting was markedly effective for the treatment of depressed acne scars, which is worthy of clinical promotion and application.

Objective To preliminarily explore the potential efficacy of Xuesaitong Soft Capsule(XST)against post-stroke depression(PSD),and to investigate the material basis of XST's anti-PSD effect based on the metabolomics results to analyze its related pharmacokinetic(PK)characteristics and further analyze the pharmacodynamic(PD)equation of representative ingredients.Methods The initial evaluation of drug effica-cy was conducted by detecting the depressive-like behavior and neurotransmitter levels in rats.The Pearson correlation analysis was employed to analyze the correlation between the main metabolites regulated by XST and the saponin components entering the bloodstream.At various time points after drug administration,the blood concentration of ginsenoside Re and the concentration of norepinephrine(NE)in the serum of PSD rats were measured,and the compartment model was fitted accordingly.Furthermore,the liquid chromatography-mass spectrometry was utilized to determine the content of ginsenoside Re in the liver,spleen,kidney,prefron-tal cortex,hippocampus and striatum of PSD rats.Results Ginsenoside Re showed the optimal correlation by the Pearson correlation analysis.Based on its pharmacokinetic parameters,the pharmacodynamic equation with NE was E=160.462 × Ce/(38.663+Ce).The contents of ginsenoside Re in the liver,spleen,kidney,prefron-tal cortex,hippocampus and striatum of rats were(17.23+11.90),(19.05+5.67),(1.95+0.79),(70.13+6.75),(57.03+3.11),and(72.45+5.45)ng/g,respectively.Conclusion XST could improve the depressive-like behaviors in PSD rats by regulating the expression levels of neurotransmitter NE and 5-HT.Ginsenoside Re may be the pharmacodynamical material foundation for XST's preventative treatment of PSD.

To provide prevention and control strategies of occupational exposure risks to cytotoxic drug in medical institutions， improve the awareness of protection among medical staff，and reduce potential occupational exposure risks，the Guidelines for the Prevention and Control of Occupational Exposure Risk to Cytotoxic Drugs in Medical Institutions is developed. Based on the World Health Organization Guidelines Development Manual，the exposure risk issues of the cytotoxic drug collected from the time that it entered the hospital to the several stages after delivery to hospital，such as transportation，receipt，storage，unpacking，dispensing，use of finished products，and waste disposal. Delphi method is used to construct identification of clinical issues，and evidence-based research method is used to develop relevant evidence. Quality evaluation is conducted by using the recommended GRADE method. The consensus is reached on the recommendation opinions and evidence levels through expert consensus method. By combining engineering controls，administrative controls and personal protective equipment at different levels，a graded control approach is established. A total of 37 clinical issues are identified，resulting in 36 recommendations. This guideline provides reference and supplementation for the formulation of cytotoxic drug prevention and control measures in medical institutions.

Single-cell or low-input multi-omics techniques have revolutionized the study of pre-implantation embryo development.However,the single-cell or low-input proteomic research in this field is rela-tively underdeveloped because of the higher threshold of the starting material for mammalian embryo samples and the lack of hypersensitive proteome technology.In this study,a comprehensive solution of ultrasensitive proteome technology(CS-UPT)was developed for single-cell or low-input mouse oocyte/embryo samples.The deep coverage and high-throughput routes significantly reduced the starting material and were selected by investigators based on their demands.Using the deep coverage route,we provided the first large-scale snapshot of the very early stage of mouse maternal-to-zygotic transition,including almost 5,500 protein groups from 20 mouse oocytes or zygotes for each sample.Moreover,significant protein regulatory networks centered on transcription factors and kinases between the MII oocyte and 1-cell embryo provided rich insights into minor zygotic genome activation.
