Objective:To explore the prognostic value of serum free light chain in chronic lymphocytic leukemia patients.Methods:Retrospective cohort study was conducted. One hundred and fifty-six newly diagnosed chronic lymphocytic leukemia(CLL) patients in the first affiliated hospital of Nanjing Medical University from January 2016 to December 2020 were included in the retrospective analysis. Among them, there were 106 males and 50 females, with a median age of 60.7 (53.4, 66.0) years old.Serum sample was collected, serum free light chains were detected, and patients were divided into a treatment group (106 cases) and a follow-up group (50 cases) based on the presence of treatment indications.The threshold of serum free light chain(sFLC) was defined by the reference range of the instruction manual and ROC curve. Three indicators were used, including sFLCR, sFLC(κ+λ) and sFLC(κ-λ). Patients were divided into normal sFLCR group ( n=61)and abnormal group( n=95), as well as sFLC (κ+λ) low value group ( n=88) and high value group ( n=68), and sFLC (κ-λ) low value group ( n=64) and high value group ( n=92).The abnormal group and high value group were enrolled as the experimental group, while the normal group and low value group were enrolled as control group. Chi-square test and Fisher′s exact test were used to compare the clinical data, cytogenetics, and molecular biology characteristics of patients in two groups, Kaplan-Meier method was used to analyze the median treatment-free survival (TFS) of the patients, and Cox regression was used to screen the prognostic factors of the patients. Results:The proportion of Rai stage Ⅰ-Ⅳ ( χ2=8.16, P<0.05 and χ2=7.63, P<0.05 and χ2=5.45, P<0.05), Binet stage B-C( χ2=4.11, P<0.05 and χ2=9.43, P<0.05 and χ2=7.34, P<0.05), β 2-microglobulin>3.5 mg/L( χ2=5.13, P<0.05 and χ2=18.3, P<0.05 and χ2=12, P<0.05), ATM gene mutation rate( χ2=6.21, P<0.05 and χ2=4.88, P<0.05 and χ2=5.19, P<0.05), and immunoglobulin heavy chain variable region (IGHV) mutation free rate ( χ2=18.9, P<0.05 and χ2=24.6, P<0.05 and χ2=10.4, P<0.05)in the experimental group were significantly higher than that in control group 1 ( P<0.05). Multivariate analysis indicated that sFLC(κ+λ) ( HR=1.615,95% CI 1.012-2.576, P=0.044), β 2-microglobulin>3.5 mg/L( HR=2.103,95% CI 1.356-3.262, P=0.001) and TP53 deletion and/or mutation( HR=1.892,95% CI 1.082-3.308, P=0.025) were independent prognostic factors affecting the patients time to first treatment(TFT). Conclusions:Serum free light chains can predict the risk of early treatment and have good prognostic significance in newly diagnosed CLL patients.

Objective To analyze the law of acupoint selection and compatibility of acupuncture and moxibustion and the application law of acupuncture and moxibustion in the treatment of lactational mastitis using complex network technology.Methods The clinical research literature about acupuncture and moxibustion treatment of lactational mastitis was retrieved from CNKI,CBM,Wanfang Data,VIP and PubMed from the establishment of the databases to March 15,2025.The literature was screened according to the standards to build a prescription database of acupuncture and moxibustion treatment of lactational mastitis.SPSS Modeler 18.0 software was used to analyze association rules,and Gephi 0.9 software was used for complex network analysis.Results A total of 108 articles were included.141 acupuncture and moxibustion prescriptions were extracted,involving 74 acupoints,with a total use frequency of 677 times.The high-frequency acupoints were Jianjing,Danzhong,Rugen,Zusanli,Neiguan,etc.Specific acupoints were mainly composed of Wushu acupoints(169 times,21.10%);the acupoints were mainly distributed in the limbs(36);the most frequently used meridian was stomach meridian(168 times,24.82%).The combination of acupoints with the highest correlation was Jianjing-Neiguan-Rugen.Complex network analysis identified 22 core acupoints,with the most commonly used acupuncture method being filiform needle acupuncture(79 times).Conclusion Acupuncture and moxibustion treatment of lactational mastitis pays special attention to the selection of stomach meridian.The compatibility mode is mainly from top to bottom,and the corresponding acupoints are selected according to syndrome differentiation.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic airway inflammatory disorder characterized by persistent airflow limitation, involving complex inflammatory responses and airway structural remodeling in its pathophysiological process. Recent studies indicate that the Transforming Growth Factor-β-Activated Kinase 1 (TAK1) signaling pathway plays a pivotal regulatory role in the pathogenesis and progression of various pulmonary diseases. This review systematically summarizes the fundamental biological functions of the TAK1 signaling pathway, with a focus on its mechanistic involvement in inflammatory responses and airway remodeling in COPD. Additionally, we synthesize recent advances in targeted therapeutic strategies, including TAK1 inhibitors, and evaluate their potential clinical applications. This work aims to provide theoretical support and research direction for elucidating COPD pathogenesis and developing novel targeted therapies.

Objective:To investigate the clinicopathological features and differential diagnosis of male genital system lympho-ma(MGSL).Methods:We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 ca-ses of MGSL.Results:The onset age of the MGSL patients ranged from 4 to 85(median 62)years old.All the cases showed non-specificity of the imaging features and clinical manifestations.MGSL was located mainly in the testis(n=66),followed by the pros-tate(n=7),epididymis(n=3),scrotum(n=3)and penile glans(n=1).Diffused large B cell lymphoma(DLBCL)was the most common pathological type(n=62),next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue(MALT)(n=7)and other rare types(n=12).During the 1-112-month follow-up of 10 of the 19 patients,1 died at 1 month af-ter diagnosed with prostatic B-lymphoblastic lymphoma(B-LBL)and another 1 died at 50 months after diagnosed with testicular DLBCL.Conclusion:MGSL is rare clinically,mainly of the DLBCL type pathologically,lacking specificity in clinical symptoms and imaging manifestation.The definite diagnosis of the malignancy depends on histopathology combined with related molecular exami-nation and immunohistochemical labeling,and R-CHOP chemotherapy is the first choice for its treatment.

As the first defense of respiratory system,airway epi-thelial cells(AECs)play an important role in separating the re-spiratory internal and external environment.They are essential for the natural immune function.Small airway lesions are an im-portant early pathology of chronic obstructive pulmonary disease(COPD),when AECs are exposed to harmful particles or gases for a long time,the epithelial barrier is damaged,and the signa-ling pathways which involved in differentiation,repair,and in-flammatory are disordered,resulting in epithelial cell cycle stag-nation and accelerated aging.A number of studies have sugges-ted that AECs of COPD patients express high levels of aging markers,suggesting that senescence of AECs is closely related to COPD.This review discusses the potential mechanisms of AECs senescence in COPD,the impact of AECs senescence on the de-velopment and severity of the disease,and highlights potential targets for modulating cellular senescence in airway epithelium as a therapeutic approach in COPD.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

Objective To evaluate the inhibitory effect of Lactobacillus plantarum mouthwash on the progression of caries in isolated teeth.Methods Human isolated teeth were infected with Streptococcus mutans solution,and treated with saline,commercial mouth-wash,and Lactobacillus plantarum mouthwash,respectively,for 28 days.Tooth changes were recorded to assess their inhibitory effect on caries progression by light microscopy and scanning electron microscopy.Results Lactobacillus plantarum had an inhibitory effect on caries progression,with significant effects on deep dentinal caries in pit and fissure,and similar efficacy to commercial mouthwash on smooth surface caries.Calcium loss in dentin tubules was observed under an electron microscope,with Lactobacillus plantarum group less than commercial group and saline group.Conclusion Lactobacillus plantarum mouthwash can inhibit the growth of Streptococcus mutans and effectively prevent caries,particularly in controlling the progression of deep pit and fissure caries.

In this study, araucarene diterpenes, characterized by a pimarene skeleton with a variably oxidized side chain at C-13, were investigated. A total of 16 araucarene diterpenoids and their derivatives were isolated from the woods of Agathis dammara, including 11 previously unreported compounds: dammaradione (1), dammarones D-G (2, 5, 14, 15), dammaric acids B-F (8-12), and dammarol (16). The structures of these new compounds were elucidated using high-resolution electrospray ionization mass spectroscopy (HR-ESI-MS) and one-dimensional/two-dimensional (1D/2D) nuclear magnetic resonance (NMR), while their absolute configurations were determined through the electronic circular dichroism (ECD) exciton chirality method and Snatzke's method. The hypoglycemic activity of all isolated compounds was evaluated using a transgenic zebrafish model, and a structure-activity relationship (SAR) analysis was conducted. Araucarone (3) and dammaric acid C (9), serving as representative compounds, demonstrated significant hypoglycemic effects on zebrafish. The primary mechanism involves the promotion of pancreatic β cell regeneration and glucose uptake. Specifically, these compounds enhance the differentiation of pancreatic endocrine precursor cells (PEP cells) into β cells in zebrafish.

OBJECTIVE: Observational studies have found associations between inflammatory bowel disease (IBD) and the risk of dementia, including Alzheimer's dementia (AD) and vascular dementia (VD); however, these findings are inconsistent. It remains unclear whether these associations are causal. METHODS: We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia. Mendelian randomization (MR) analysis based on summary genome-wide association studies (GWASs) was performed. Genetic correlation and Bayesian co-localization analyses were used to provide robust genetic evidence. RESULTS: Ten observational studies involving 80,565,688 participants were included in this meta-analysis. IBD was significantly associated with dementia (risk ratio [ RR] =1.36, 95% CI = 1.04-1.78; I ² = 84.8%) and VD ( RR = 2.60, 95% CI = 1.18-5.70; only one study), but not with AD ( RR = 2.00, 95% CI = 0.96-4.13; I ² = 99.8%). MR analyses did not supported significant causal associations of IBD with dementia (dementia: odds ratio [ OR] = 1.01, 95% CI = 0.98-1.03; AD: OR = 0.98, 95% CI = 0.95-1.01; VD: OR = 1.02, 95% CI = 0.97-1.07). In addition, genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia. CONCLUSION Our study did not provide genetic evidence for a causal association between IBD and dementia risk. The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.
