Malignant tumors(commonly referred to as cancer)represent a major global public health challenge and contribute significantly to the worldwide disease burden.Early screening plays a critical role in improving detection rates,enabling timely intervention,and enhancing pa-tient survival rates.However,current cancer screening guidelines primarily focus on site-specific screening,which may not fully address the need for comprehensive early detection.A scientifical-ly rational,multi-cancer screening approach offers several advantages:it optimizes the use of bio-logical samples,reduces time costs for participants,enhances the efficiency and comprehensive-ness of screening,and minimizes overall expenses.Such an approach also facilitates the rational allocation of healthcare resources,ultimately helping to reduce the societal burden of cancer.To address this need,the Cancer Epidemiology Committee of the Chinese Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers in China.This consensus integrates multidisciplinary expertise and synthesizes the latest domestic and interna-tional researches on cancer screening,early detection,and treatment for prevalent malignancies.Drawing upon China's unique demographic and healthcare context,as well as practical screening experiences,the consensus provides evidence-based recommendations on target populations,screening technologies,and procedural workflows for multi-cancer screening.These guidelines align with the principles and methodologies established by the World Health Organization(WHO),aiming to:enhance the effectiveness of combined cancer screening in China,improve early detec-tion rates,and provide a scientific foundation for national cancer prevention and control strategies.

Objective:To explore the role of autophagy in the effects of titanium(Ti)nanotopography on macrophage polarization and inflammatory cytokine secretion under inflammatory microenvironment.Methods:4 groups were set as negative control(NC,on tissue culture plate),polished pure Ti surface(P),30 nm diameter nanotube(NT-30),and NT-30 with 3-Methyladenine(3-MA)treatment.Macrophage cell line RAW264.7 was cultured on different surfaces for 3 d and treated by LPS for 24 h.The autophagy was examined by transmission electron microscopy and Western blot while the cell morphology was observed by scanning electron mi-croscopy.The secretion of inflammatory cytokines was measured by Cytokine Array.Results:Under LPS stimulation,the autophagic degradation activity was significantly enhanced on Ti samples.On NT-30 surface,the autophagosomes formation was significantly in-creased,which was decreased after 3-MA treatment.Meanwhile,cells were obviously elongated on NT-30 surface and returned to spherical shape after 3-MA treatment.In addition,the pro-inflammatory cytokines and anti-inflammatory cytokines were significantly decreased and increased respectively on Ti surfaces,in which the NT-30 surface was the most obvious.After 3-MA treatment,the anti-inflammatory effect of NT-30 surface was inhibited.Conclusion:In inflammatory microenvironment,titania nanotubes surface could enhance autophagy activity to realize anti-inflammatory effect.

Objective:To analyze the clinical characteristics and cytokines expression characteristics in infants with mild and severe respiratory syncytial virus (RSV) infection.Methods:From May 2023 to December 2023, plasma samples and clinical information were collected from 16 infants with RSV infection and 14 control infants. Cytek Aurora flow cytometry (Cytek, America) and Enzyme linked immunosorbent assay (ELISA) were used to detect the expression levels of 25 cytokines after mild and severe RSV infection.Results:Cough and nasal obstruction were the main clinical manifestations in infants with mild RSV infection, accompanied by polypnea, wheezing and other symptoms. The main symptoms of severe RSV infection were cough and rales, accompanied by fever and polypnea. In comparison with the control group, the expression levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-13, IL-22, TNF-α, IFN-α, IFN-β, MIP-1β, I-TAC, ENA-78, GROα, Eotaxin, and MCP-1 in the RSV infection group all exhibited an upregulation trend. Both IP-10 and MIP-3α demonstrated a downward trend in the RSV infection group; however, there was no statistically significant difference ( P>0.05). The levels of IL-10, IFN-γ, MIP-1α, and IL-8 in the RSV infection group were significantly higher than those in the control group, whereas the levels of MIG, TARC, and RANTES in the RSV infection group were significantly lower than those in the control group ( P<0.05). The levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-22, IFN-β, IFN-γ, TNF-α, IL-8, I-TAC, MIP-1β, Eotaxin, and MCP-1 in the mild RSV infection group were significantly higher than those in the severe RSV infection group ( P>0.05). Among these, the levels of MIG, RANTES, TARC, MIP-3α, and ENA-78 in the mild infection group were all lower than those in the severe infection group. The expressions of ENA-78 and MIP-1α in the severe infection group were significantly higher than those in the mild infection group and also higher than those in the control group. There was no significant difference in IP-10 and GROα between the mild and severe RSV infection groups ( P>0.05). Conclusions:The differences in clinical features and cytokines between infants with mild and severe RSV infection provide important data support for the prevention and treatment of RSV infection in infants.

Meta integration method was used to integrate and analyze the literature findings.Results:A total of 11 articles were included in the review, from which 22 research findings were extracted and categorized into 7 groups, culminating in 3 integrated outcomes: IBD patients experienced complex emotions, IBD patients faced multiple pressures and IBD patients had ambivalent coping.Conclusions:IBD patients manifest profound psychological complexities throughout dietary management processes. Future healthcare professionals can implement multifaceted psychological intervention strategies to relieve psychological distress, promote positive emotion, overcome negative coping, and ultimately enhance the competence of dietary self-management among IBD patients.

Background and purpose:High-throughput detection of plasma cell-free DNA(cfDNA)is widely used for multi-cancer targeted therapy drug screening,and this study investigated the relationship between the type and number of plasma cfDNA class Ⅰ and Ⅱ targeted therapy-related gene variants and cancer survival in patients with non-small cell lung cancer(NSCLC).Methods:The sequencing results and clinical data of NSCLC patients who underwent tumor plasma cfDNA high-throughput sequencing projects in Sun Yat-sen University Cancer Center from 2021 to 2023 were collected.The survival follow-up of enrolled patients was carried out from the day of plasma collection on June 1,2021 to May 27,2024,and GraphPad Prism 8.0 and SPSS Statistics 25.0 were used.Univariate and multivariate statistical analyses were conducted on the types and numbers of class Ⅰ and class Ⅱ targeted therapy-related genes in the survival and clinical data of patients and sequencing results(Ethical approval:B2024-359-01).Results:A total of 313 patients included in this study with NSCLC were categorized into stage Ⅰ 25 patients(7.98%),stageⅡ 20 patients(6.39%),stage Ⅲ 38patients(12.14%),and stage Ⅳ 230 patients(73.48%).Pathological diagnosis results showed that adenocarcinoma accounted for 90.10%,squamous cell carcinoma accounted for 5.11%,large cell carcinoma accounted for 2.87%and other classifications accounted for 1.92%.The number and the percentage of class Ⅰ and class Ⅱ targeted therapy drug-related genes in the plasma cfDNA NSCLC patients were 0(25.24%),1(17.57%),2(19.17%),3(14.38%),4(8.31%),and 5 or more(15.34%).The results of statistical analysis showed that 3 genes with the highest mutation frequencies were EGFR,TP53 and ERBB2,and the mutation frequency of EGFR gene was 36.04%.The mutation frequency of TP53 gene was 30.63%.The mutation frequency of ERBB2 gene was 4.95%.The survival time of patients is related to not only the expression of hotspot targeted genes,but also the number of class Ⅰ and Ⅱ target-related gene variants detected by plasma cfDNA high-throughput sequencing.The survival time of the patients with no targeted therapy-related locus variants after treatment was longer compares with targeted therapy-related locus variants,which can reduce the risk of death by 63.2%.However,patients with a single gene locus variant had longer survival time and lower risk of death than those with multiple driver locus variants,and the measured class Ⅰ and Ⅱ targeted therapy drugs were within 3 genes.Overall,the smaller the number of genes,the longer the survival.Conclusions:The number of class Ⅰ and class Ⅱtargeted therapy-related gene variants in plasma cfDNA high-throughput sequencing also has an effect on the survival of patients after treatment.Plasma cfDNA level detected by high-throughput sequencing could be a prognostic factor for the NSCLC patients.

The decrease in blood glucose in perinatal dairy cows affects the energy supply and im-mune function of peripheral blood neutrophils(PMN).Fibroblast growth factor 21(FGF21)is an important regulator of glucose metabolism,and serum FGF21 levels in some perinatal cows are significantly elevated after farrowing.In order to explore the effect of FGF21 on PMN glucose ho-meostasis in perinatal dairy cows,the cows were divided into high FGF21 group(high FGF21,n=8,FGF21＞800 ng/L)and low FGF21 group(low FGF21,n=8,FGF21＜200 ng/L)within 3 weeks postpartum.The results showed that compared with the low FGF21 group,the glucose up-take of PMN and the mRNA expression of glucose transporters SLC2A1 and SLC2A3 were signifi-cantly increased in the high FGF21 group.The activities of phosphofructokinase 1(PFK1)and glu-cose-6-phosphate dehydrogenase(G6PDH)were significantly increased,and the activity of glyco-gen synthase(GCS)was significantly decreased in PMN in the high FGF21 group.The lactate con-tent and ATP content of PMN were significantly increased,and the mRNA and protein expressions of hexokinase(HK2)and PFK1 were significantly increased in the high FGF21 group.These re-sults indicated that the uptake and utilization of glucose by PMN in perinatal peripheral blood FGF21 increased to ensure the ATP supply of PMN,which provided a theoretical basis for the pro-posal of a new strategy to alleviate immunosuppression in perinatal dairy cows.

Objective To explore the role of Erianin in atopic dermatitis(AD)and its regulatory mechanism involving the high-mobility group box 1(HMGB1)/receptor for advanced glycation end products(RAGE)-Ras homolog gene family member A(RhoA)/Rho-associated protein kinase 1(ROCK1)signaling pathway.Methods An AD model was induced in BALB/c mice using 1-chloro-2,4-dinitrobenzene(DNCB).Skin thickness and spleen and lymph node weight were measured and pathological changes in the back skin and ears were detected using methylamine blue and hematoxylin and eosin staining.Inflammatory factors were detected by enzyme-linked immunosorbent assay.An in vitro model of AD was established in HaCaT cells stimulated by tumor necrosis factor(TNF)-α.Cellular reactive oxygen species(ROS)were detected by flow cytometry and mitochondrial ROS(mtROS)were detected by immunofluorescence assay.Cell apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick-end labeling.HMGB1,RAGE,RhoA,and ROCK1 proteins were detected by Western blot.Results Erianin inhibited the increase in skin thickness,reduced the spleen and lymph node weights,improved the infiltration of inflammatory cells and the degranulation of mast cells,and reduced the levels of inflammatory factors(P＜0.05).Erianin also reduced the production of cellular ROS and mtROS induced by TNF-α in vitro(P＜0.01),and decreased the protein expression of HMGB1,RAGE,RhoA,and ROCK1(P＜0.01).Treatment of HMGB1-stimulated HaCaT cells with a RAGE-specific blocker(TFA)had no effect on HMGB1 expression,while expression levels of RAGE,RhoA,and ROCK1 were decreased(P＜0.01).Cells treated with the Rho kinase inhibitor Y-27632+r-HMGB1 group showed similar result to the TFA+r-HMGB1 group,except for RAGE.Conclusions Erianin relieves AD by regulating the HMGB1/RAGE-RhoA/ROCK signaling pathway.

Objective:To investigate the effect of ginkgolide B(GB)on astrocyte(AST)phagocytosis of myelin debris,and to investigate the mechanism of this functional therapy to demyelination by targeting AST.Methods:In vitro culture of AST,and divided AST into three groups:Control group,Myelin debris(Debris)group and Debris+GB group,incubed them in a constant temperature CO2 cell culture incubator for 24 hours,and then detected relevant indicators to observe the effect of GB on AST on phagocytic myelin debris.Results:Compared to the phagocytosis of myelin debris by primary AST,GB could effectively promote the phagocytosis by AST and show enhanced ABCA-1 expression(both P<0.05).Phagocytosis of myelin debris had no effect on the secretion of inflammatory cytokines by in vitro cultured AST.Debris+GB increased the expressions of neurotrophic CNTF and B-FGF compared to Debris(both P<0.05).Furthermore,Debris+GB decreased Bax and Caspase-3,while increased Bcl-2 expression(all P<0.05).Conclusion:GB can promote the phagocytosis of myelin debris by AST,which may be related to the upregulation of ABCA-1.Meanwhile,phagocytosis of myelin debris by AST increases the expression of the neurotrophic factors and the inhibits the apoptosis of AST themselves.
