With the widespread application of low-dose computed tomography (CT), the detection rate of multiple lung cancers (MLCs) is gradually increasing. The diagnosis and treatment of MLCs have become a major challenge in clinical practice in thoracic surgery and oncology. In April 2025, the Lung Cancer Professional Committee of the China Anti-Cancer Association (CACA) organized multidisciplinary experts from both domestic and international fields to release the first edition of the CACA Expert Consensus on the Diagnosis and Treatment of Multiple Lung Cancers, providing systematic recommendations for the diagnostic system, molecularassessment strategies, and surgical and non-surgical management of MLCs. This article provides a detailed interpretation of the core content of this consensus and, by incorporating the latest research progress in the field, delves into the pathogenesis, precise diagnostic strategies, and individualized treatment pathways for multiple lung cancers, aiming to offer a more comprehensive reference for clinical practice.

The paper discusses the scientific connotation of"heart and brain co-dominating the mind",including the connotation of"heart and brain co-dominating the mind"in traditional Chinese medicine and the physiological and pathological relationship be-tween heart and brain in modern medicine.Based on the understanding of"heart and brain co-dominating the mind",this paper be-lieves that"restlessness of mind"is the core pathogenesis of insomnia,and regulating mind is the key to the acupuncture and moxibus-tion treatment of insomnia.The autonomic nervous system(ANS)is a bridge connecting the heart and brain,and is closely related to the central anatomy,neurotransmitters and physiological rhythms of sleep.The imbalance of ANS is highly consistent with the patho-genesis of"heart and brain restlessness"in traditional Chinese medicine.The Governor Vessel runs through the brain and the heart,and the"Governor Vessel regulating spirit acupuncture"can communicate the heart and brain,regulate ANS function,and thus im-prove sleep quality.

Background and purpose:Next generation sequencing-identified genetic alterations of diffuse large B cell lymphoma(DLBCL)and baseline SUVmax detected by 18F-FDG PET/CT were correlated with patients'prognosis.However,their relationship and the associations with R-CHOP response of DLBCL are still unclear.This study aimed to analyze the association bewteen genetic alterations and 18F-FDG PET/CT SUVmax and their correlations with clinicopathological characteristics and R-CHOP response of DLBCL.Methods:A total of 225 cases of primary DLBCL detected by next generation sequencing using 481 lymphoma gene panel and examined by 18F-FDG PET/CT before treatment between 2022 and 2023 were collected.This study was approved by the Ethics Committee of Fudan University Shanghai Cancer Center(Ethical No.:050432-4-2307E)and acquired the informed consent of the patients.The translocations of BCL2,BCL6 and MYC were identified by fluorescence in situ hybridization.The clinicopathological characteristics and the PET/CT scan after R-CHOP chemotherapy were collected.Results:Finally,191 patients were enrolled in this study.The frequency of MYD88 mutation,TP53 mutation,copy number variations of CDKN2A/2B,CD79B mutation in the 191 DLBCL patients were 24.6%,27.2%,32.5%and 16.8%,respectively.The range of baseline SUVmax was 5.10-63.10(24.44±10.70,median 22.80).The baseline SUVmax of MYD88L265P DLBCL was significantly higher than that of MYD88 wild type(P=0.039).There were no significant associations of SUVmax with other gene alterations including TP53 mutation,CDKN2A/B loss,CD79B mutation,KMT2D mutation,TNFAIP3 mutation,B2M mutation,EZH2 mutation,BTG1/2 mutation,CREBBP mutation,gene translocations of MYC,BCL2 and BCL6.The higher SUVmax before treatment was correlated with higher serum lactate dehydrogenase(LDH)level(P=0.012)and non-germinal center B-cell-like(non-GCB)DLBCL(P=0.040).However,there was no significant association of SUVmax with R-CHOP response(P=0.714).TP53 mutation was significantly associated with the poor response of R-CHOP(P=0.001)and was an independent predictor of non-complete metabolic response(non-CMR).TP53 mutation combined with Ann Arbor stage,International Prognostic Index(IPI)score and serum LDH level could better predict R-CHOP response than each factor alone.Conclusion:MYD88L265P DLBCL had higher baseline 18F-FDG PET/CT SUVmax.The baseline SUVmax was not associated with R-CHOP response.However,TP53 mutation was significantly correlated with poor response of R-CHOP in DLBCL patients.TP53 mutation combined with clinicopathological characteristics could better predict R-CHOP response.The associations of gene alterations and SUVmax with prognosis of DLBCL patients needed to be explored in the future.

Objective:To investigate whether biochanin A(BCA)has a protective effect against dextran sodium sulfate(DSS)-in-duced ulcerative colitis(UC)in mice.Methods:Thirty C57BL/6N mice were randomly divided into normal control group,DSS model group,sulfasalazine(SASP)-positive drug control group,and low/medium/high-dose(5 mg/kg,10 mg/kg,and 20 mg/kg)BCA groups.The mouse model of UC was induced by administering 2.5%DSS aqueous solution for 7 days.During the experimental period,both the normal control and model groups were given 0.5%carboxymethyl cellulose sodium solution daily by gavage.The positive control group was given 100 mg/kg SASP,while the BCA groups were given BCA suspensions at doses of 5 mg/kg,10 mg/kg,and 20 mg/kg.The ad-ministration lasted for 10 days.Body weight changes and fecal status of the mice were recorded every day;the colon was dissected,col-lected,and measured for its length.The colon was stained with Hematoxylin-Eosin for pathomorphological study.Quantitative poly-merase chain reaction was used to determine the levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)in the colon.Immunofluorescence was used to determine the expression of tight junction proteins,zonula occluden-1(ZO-1)and occludin,in the colon.Results:It showed that 5 mg/kg and 10 mg/kg BCA significantly alleviated weight loss in mice with UC,while 5 mg/kg,10 mg/kg,and 20 mg/kg BCA reduced the disease activity index scores.Additionally,BCA showed similar effects to SASP in improving the structure and reducing the shortening of the colon in mice with UC.Compared with the model group,all BCA groups had significantly decreased TNF-α(P=0.024、P=0.060、P=0.003)and IL-6(P=0.002、P<0.001、P<0.001)and significantly increased IL-10(P=0.006、P=0.003、P<0.001),with varying degrees of up-regulated expression of tight junction proteins.Conclusion:BCA can effectively alleviate DSS-induced symptoms,reduce intes-tinal damage,and protect the intestinal barrier in mice with UC.

Objective:This study sought to examine the clinicopathological features of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) and to discuss its differential diagnosis.Methods:A total of 36 MEITL cases, collected between June 2015 and January 2024 from the Fourth Affiliated Hospital of Soochow University and the First Affiliated Hospital, College of Medicine, Zhejiang University, were analyzed. Patients underwent immunohistochemistry, in situ hybridization for Epstein-Barr virus-encoded small RNA (EBER), and T-cell receptor (TCR) gene rearrangement testing. Clinical data, laboratory results, and follow-up information were collected for correlation analysis.Results:The cohort included 36 patients (20 males and 16 females) aged 17-76 years (median: 57 years). Tumors outside the intestine were observed in 22 cases (61%). A total of 32 patients (89%) underwent surgical intervention and/or chemotherapy, and one patient received auto-HSCT. The median follow-up duration was 11.5 months (range: 8-73 months), with a median overall survival of 6 months (range: 1-67 months) ; 34 patients died during the follow-up period. Morphologically, nine cases (25%) exhibited significant pleomorphism. Immunohistochemical analysis revealed that high expression levels of both P53 and c-Myc were correlated with atypical morphology ( P=0.003 and P=0.016, respectively). Notably, patients with high P53 expression had significantly shorter survival times than those with low P53 expression ( χ2=4.922, P=0.027), whereas survival did not differ significantly based on c-Myc expression levels ( χ2=0.034, P=0.854). Furthermore, a PD-L1 CPS score ≥10 was observed in 22 cases (68.8%). Scattered EBER positivity in background cells was identified in four cases. All tested cases (17/17, 100.0%) showed clonal TCR gene rearrangements. Conclusions:MEITL is a rare but highly aggressive lymphoma with distinct clinical and pathological features. A subset of cases may exhibit atypical morphological patterns, complicating the diagnostic process. Improving awareness of this neoplasm is helpful for early and precise diagnosis as well as the estabolishment of novel therapy regimen.

Objective:To analyze the incidence of adverse treatment outcome of rifampicin-resistant tuberculosis (RR-TB) patients and influencing factors in 9 provinces in China.Methods:The information about the basic characteristics, diagnosis and treatment of RR-TB patients registered from January 1, 2017 to December 31, 2021 in 9 provinces (Beijing, Jilin, Shanghai, Jiangsu, Zhejiang, Hubei, Henan, Yunnan and Guizhou) were collected from the tuberculosis information management sub-system of China Disease Control and Prevention Information System for a descriptive analysis, and the influencing factors of adverse treatment outcome were identified by binary logistic regression analysis.Results:In 18 204 RR-TB patients in this study a total of 6 852 had adverse treatment outcomes (37.64%). Treatment failure occurred in 1 031 patients, 1 272 patients died, 2 284 patients were lost to follow-up, and 2 265 patients were not evaluated. The results of multivariate logistic regression analysis showed that being man (a OR=1.54, 95% CI: 1.43-1.66), age ≥65 years (a OR=2.42, 95% CI: 2.20-2.67), being from other ethnic groups (a OR=1.18, 95% CI: 1.03-1.35), being farmer (a OR=1.22, 95% CI: 1.13-1.32), being retired with honours or being retired (a OR=1.16, 95% CI: 1.00-1.35) and being floating population (a OR=1.23, 95% CI: 1.13-1.34), re-treatment (a OR=1.33, 95% CI: 1.24-1.42), long-term treatment therapy (a OR=3.26, 95% CI: 2.52-4.23), living in central provinces (a OR=2.76, 95% CI: 2.55-2.99), living in western provinces (a OR=2.31, 95% CI: 2.08-2.57) were the influencing factors for adverse treatment outcome of RR-TB. Conclusions:The incidence of adverse outcomes in RR-TB patients in 9 provinces in China was higher from 2017 to 2021. There were many influencing factors associated with adverse treatment outcome in RR-TB patients, especially the area specific factors. The national tuberculosis control program should strengthen the follow-up and treatment management of RR-TB in men, the elderly, floating population, people in central and western provinces and other key groups, actively promote the short-term treatment program and improve the allocation of medical resources to reduce the influencing for adverse treatment outcomes in RR-TB patient.

Objective:To observe the regulatory effects of Tongfenglian capsule on intestinal flora,inflammatory factors and other indicators of gout in rats with gout arthritis(GA),and to explore possible mechanism of Tongfengli capsule on GA.Methods:A total of 36 male SD rats were randomly divided into blank group,Tongfenglian low,medium and high doses(0.216 g/kg,0.432 g/kg,0.864 g/kg)groups,colchicine group(0.18 mg/kg)and model group.Blank group and model group were given the same amount of distilled water,other groups were given the corresponding drug once a day for 14 days.On the 13th day after gavage,GA rat models were prepared according to Coderre modeling method,0.2 ml normal saline was injected into the right ankle joint for blank group,and general conditions of rats were dynamically observed to determine whether the model was established,and the time was recorded.Rate of foot swelling in each group was calculated.Abdominal aorta blood,colon tissue and intestinal contents of rats were collected,and colon length,pathological changes of colon tissue,serum levels of inflammatory factors(IL-1β,TLR4),mRNA expressions of NF-κB and TLR4 inflammatory pathway in intestinal tissue,and intestinal flora of rats were detected.Results:Compared with blank group,swelling rate of ankle joint,serum IL-1β and TLR4 levels,and mRNA expressions of TLR4 and NF-κB in intestinal tis-sue were significantly increased in model group,and a large number of inflammatory cells were infiltrated in the colon by HE staining,showing typical inflammatory pathological changes,colon length decreased significantly,intestinal flora richness and diversity de-creased,ratio of Firmicutes to Bacteroidetes increased,the abundance of Lactobacillus and Bifidobacterium decreased,and the abun-dance of Prevotella and Escherichia coli-Shigella increased.Compared with model group,all the indexes in all Tongfenglian groups were improved,the richness and diversity of intestinal flora were increased,and the reduction of intestinal microbial diversity and mi-crobial community structure caused by monosodiumurate were changed.Conclusion:Mechanism of Tongfenglian capsule alleviating inflammation may be related to the regulation of TLRs/NF-κB signaling pathway.Through the mediation of intestinal flora,Tongfengli-an capsule plays a role in regulating intestinal homeostasis,improving the abundance and diversity of intestinal microorganisms,and playing an intervention role in GA.This microecological intervention mechanism may be a potential means to prevent and treat GA.
