In both conferences, lung cancer immunotherapy remained a hot topic of considerable interest. This article aims to summarize and discuss the important research progress on perioperative immunotherapy for non-small cell lung cancer reported at the two conferences.

Smoking is a well-established risk factor for periodontitis, yet the precise mechanisms by which smoking contributes to periodontal disease remain poorly understood. Recent advances in spatial transcriptomics have enabled a deeper exploration of the periodontal tissue microenvironment at single-cell resolution, offering new opportunities to investigate these mechanisms. In this study, we utilized Visium HD single-cell spatial transcriptomics to profile gingival tissues from 12 individuals, including those with periodontitis, those with smoking-associated periodontitis, and healthy controls. Our analysis revealed that smoking disrupts the epithelial barrier integrity, induces fibroblast alterations, and dysregulates fibroblast-epithelial cell communication, thereby exacerbating periodontitis. The spatial analysis showed that endothelial cells and macrophages are in close proximity and interact, which further promotes the progression of smoking-induced periodontal disease. Importantly, we found that targeting the endothelial CXCL12 signalling pathway in smoking-associated periodontitis reduced the proinflammatory macrophage phenotype, alleviated epithelial inflammation, and reduced alveolar bone resorption. These findings provide novel insights into the pathogenesis of smoking-associated periodontitis and highlight the potential of targeting the endothelial-macrophage interaction as a therapeutic strategy. Furthermore, this study establishes an essential information resource for investigating the effects of smoking on periodontitis, providing a foundation for future research and therapeutic development for this prevalent and debilitating disease.

Ghrelin is a newly discovered gastrointestinal peptide that is involved in regulating the body's growth,development and energy balance,and plays a key role in the occurrence and progression of malignant tumors,such as cell proliferation,migration,invasion,apoptosis,inflammatory response and vascular disease.Generate immune cell infiltration and so on.Ghrelin affects the progression of gastric cancer by activa-ting NF-κB/p65 and AMPK and other signaling pathways.Ghrelin not only assist in early screening of gastric cancer,but also function a new marker for predicting the prognosis and survival of gastric cancer patients.Ghrelin and its analogs have clinical application value in the treatment of gastric cancer-related syndromes such as cachexia or sarcopenia.

Background Acne treatment cycle lasts long and will cause facial appearance damage.Many patients are prone to psychological problems and severe patients may even experience suicidal ideation.However,the influencing factors of psychological health problems in acne patients are still unclear.Objective To investigate the mental health status of patients with moderate-to-severe acne and to analyze the influencing factors of their psychological health problems,so as to provide references for improving their mental health.Methods A total of 120 patients with moderate-to-severe acne of grades II-IV were selected as the research subjects,who were treated in the dermatology outpatient department of the Third Hospital of Mianyang from June 2021 to June 2023.All subjects were evaluated by using the Acne-Specific Quality of Life Questionnaire(Acne-QoL),Self-rating Depression Scale(SDS),Self-rating Anxiety Scale(SAS),Rosenberg Self-Esteem Scale(RSES)and Social Phobia Inventory(SPIN).According to the evaluation results of SDS,SAS,RSES,SPIN,subjects were divided into a group with mental health problems(n=21)and a group without mental health problems(n=99).Binary Logistic regression anaylsis was adopted to explore the influencing factors of psychological health problems in acne patients.Results A total of 21 patients(17.50%)were detected to have symptoms of depression,anxiety,inferiority or social dysfunction.Statistically significant difference was observed in comparison between two groups in gender,profession,acne classification,dietary habit,age,illness course as well as the factor scores of self perception,emotional function,social function and acne symptom in Acne-QoL(χ2=7.013,23.123,9.028,11.327,t=9.913,13.022,4.081,5.383,5.361,10.203,P<0.05).The results of binary Logistic regression analysis showed that the followings were risk factors for the occurrence of psychological health problems in acne patients:female(OR=2.243,95%CI:1.136～4.429),acne of grade III(OR=3.615,95%CI:1.269～10.295)or IV(OR=1.872,95%CI:1.073～3.266),course of disease≥1.6 years(OR=2.499,95%CI:1.068～5.851),a spicy or greasy diet(OR=3.811,95%CI:1.169～12.427),Acne-QoL self perception score≤18(OR=1.802,95%CI:1.227～2.646),Acne-QoL emotional function score≤18(OR=2.252,95%CI:1.016～4.992),Acne-QoL social function score≤14(OR=3.515,95%CI:1.534～8.053)and Acne-QoL acne symptom score≤18(OR=3.586,95%CI:1.098～11.715).Protective factors for psychological health problems in acne patients included age over 30 years old(OR=0.429,95%CI:0.283～0.648),occupation as professional cadre or enterprise employee(OR=0.483,95%CI:0.249～0.939)and other occupations(OR=0.276,95%CI:0.090～0.850).Conclusion A part of patients with moderate-to-severe acne may experience psychological health problems.Patients with female gender,higher acne grades,longer disease duration,preference for greasy or spicy foods and lower scores in all Acne-QoL factors have a higher risk of experiencing psychological health problems.

Objective:To investigate the impact of neuroendocrine function on postoperative complications and nutritional status in gastric cancer patients.Methods:Clinical data of 102 gastric cancer patients who underwent radical gastrectomy at the Department of General Surgery, First Affiliated Hospital of Soochow University, from Aug 2021 to Jun 2022 were retrospectively analyzed.Results:Among the 102 gastric cancer patients, 18 (17.6%) suffered from postoperative complications. Univariate analysis indicated that age, BMI, preoperative plasma ghrelin concentration, and preoperative hemoglobin levels were associated with early postoperative complications following radical gastrectomy. Multivariate analysis revealed that age, BMI, and preoperative plasma ghrelin concentration ( P<0.05) were independent risk factors for postoperative complications in gastric cancer patients. Differential analysis of ghrelin concentration demonstrated correlations with hemoglobin levels, skeletal muscle index, albumin, and creatinine, and a positive correlation with the skeletal muscle index. Conclusions:Reduced preoperative neuroendocrine hormone ghrelin concentration is an independent risk factor for postoperative complications in gastric cancer patients. Ghrelin concentration is correlated with the skeletal muscle index in these patients.

ObjectiveTo investigate the prevalence rate and influencing factors of sleep insufficiency in medical students with migraine， and to provide a reference for alleviating the sleep problems in medical students. MethodsFrom July 2018 to July 2019， a random cluster sampling method was implemented to choose 546 medical students who met the diagnostic criteria of the International Classification of Headache Disorders， third edition （ICHD-3） for migraine in North Sichuan Medical College. Students were divided into sleep sufficiency group （n=367） and sleep insufficiency group （n=179） based on whether the nightly sleep duration was more than 6 hours. General demographic and clinical data of medical students were collected. Pittsburgh Sleep Quality Index （PSQI） was used to assess the sleep quality. Hamilton Anxiety Scale （HAMA） and Hamilton Depression Scale-24 item （HAMD-24） were used to evaluate the anxiety and depression states. Visual Analogue Scale （VAS） was adopted to assess the pain degree， and the 6-item Headache Impact Test Questionnaire （HIT-6） was applied to evaluate the impact of headache on daily life. Then Logistic regression analysis was conducted to screen the influencing factors of sleep insufficiency in medical students with migraine. ResultsAmong 546 medical students with migraine， 179（32.78%） had sleep insufficiency. There were significant differences in age （t=2.107）， frequency of headache attacks （Z=-2.972）， anxiety status （χ²=14.053）， depression status （χ²=10.773）， total score of PSQI （t=-13.247） and sleep quality （χ²=94.754） between sleep sufficiency group and sleep insufficiency group （P<0.05 or 0.01）. Correlation analysis showed that sleep duration in migraine patients was negatively correlated with age （r=-0.100， P<0.01）， and positively correlated with frequency of headache attacks， anxiety status， and depression status （r=0.135， 0.169， 0.139， P<0.01）. Multivariate Logistic regression analysis denoted that age （OR=0.860， 95% CI： 0.743~0.996， P=0.045）， frequency of headache attacks （OR=1.051， 95% CI： 1.006~1.098， P=0.026） and depression status （OR=1.712， 95% CI： 1.024~2.861， P=0.040） were influencing factors of sleep insufficiency in medical students with migraine. ConclusionMedical students with migraine suffer a high prevalence rate of sleep insufficiency， moreover， the frequency of headache attack and depression status are risk factors， and age is a protective factor for sleep insufficiency in medical students with migraine.

【Objective】 To make bioinformatics analysis of inflammatory cardiomyopathy so as to screen out hub genes related to etiology and therapeutic targets. 【Methods】 Differential expression analysis of inflammatory cardiomyopathy gene chip data from Gene Expression Omnibus （GEO） Database was carried out via GEO2R tool. Protein-protein interaction（PPI）network and hub genes identification were realized by String database and CytoHubba. GO and KEGG enrichment analysis for functional annotation and pathway analysis of hub genes were conducted by R language. Web-based enrichment analysis platform Enrichr and Drug Signatures database were applied to screen out candidate drugs targeting hub genes for inflammatory cardiomyopathy. 【Results】 The 149 DEGs were statistically significant， among which 44 were upregulated and 105 were downregulated. To identify hub genes， PPI network consisting of 37 nodes and 116 edges was constructed， and 16 hub genes were NDUFB7， POLR2L， NDUFS7， UQCR11， NDUFA13， NDUFA2， PHPT1， NDUFB10， UBA52， ATP5D， NDUFA3， COX6B1， POLR2J， COX4I2， AURKAIP1 and MRPL41. Hub genes were enriched to 113 different GO terms， and the most significant terms were mitochondrial ATP synthesis coupled electron transport， respiratory electron transport chain， oxidative phosphorylation， respiratory chain， mitochondrial inner membrane， NADH dehydrogenase activity and oxidoreductase activity. DEGs were enriched to 13 different signal pathways， including oxidative phosphorylation， non-alcoholic fatty liver disease， diabetic cardiomyopathy， and cardiac muscle contraction. We screened out candidate drugs targeting hub genes， namely， metformin hydrochloride， clindamycin， and hydralazine. 【Conclusion】 Hub genes screened out by decoding the expression profiles are convolved in the etiology and mechanism of inflammatory cardiomyopathy， which might serve as latent therapeutic targets and benefit patients with inflammatory cardiomyopathy.
