The intestinal flora is a vast and complex microbial system，and its dysregulation may be associated with the occurrence and progression of various diseases.Nephrotic syndrome is a kidney disease characterized by massive proteinuria，hypoalbuminemia，edema，and hyperlipidemia.Some studies have found alterations in the intestinal flora of patients with nephrotic syndrome.Short-chain fatty acids produced by intestinal flora metabolism，particularly butyrate，may influence the occurrence and progression of nephrotic syndrome by regulating immune responses and inflammatory processes through their effects on the differentiation and function of regulatory T cells.These findings provide insights for exploring the pathophysiology of nephrotic syndrome and developing novel therapeutic strategies.

Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However， there are many toxic side effects in clinical application， which seriously hinder the treatment process. Therefore， it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine （TCM） has a long history of treating colorectal cancer and offers advantages such as safety， effectiveness， multiple targets， multiple pathways and minimal toxic side effects， which have made it increasingly popular worldwide. According to TCM， the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer， such as Jianpi compound， Jianpi Xiaoai decoction， and Bushen Jiedu Sanjie decoction. TCM monomers， such as emodin， berberine， and tanshinone， mainly focus on clearing heat and removing toxin， circulating blood and transforming stasis， and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis， and research has shown that pathways such as Wnt/β-catenin， phosphatidylinositol-3 kinase/protein kinase （PI3K/Akt）， Janus kinase 2/signal transduction and transcription activating factor 3 （JAK2/STAT3）， nuclear factors-κB （NF-κB）， vascular endothelial growth factor （VEGF） play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review， we searched various literature databases， such as PubMed， China National Knowledge Infrastructure （CNKI）， and VIP， using keywords such as "colorectal cancer"， "signaling pathway"， "invasion and metastasis"， and "traditional Chinese medicine"， to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Objective: To investigate the current prevalence of myopia and the progression of the axial length/corneal radius ratio(AL/CR) among primary school students in Jing an District, Shanghai, and to analyze the value of dynamic AL/CR monitoring and elucidate its longitudinal association with myopia progression, so as to provide evidences for supporting myopia prevention and control interventions. Methods: From 2019 to 2023, by using a stratified cluster random sampling method, 17 624 students from two primary schools in Jing an District, Shanghai were selected for annual vision screenings in five consecutive years. Additionally, a retrospective cohort of 480 eligible first grade students identified in 2019 was followed up until 2023. The analysis focused on the myopia prevalence and the trend in the AL/CR. Differences in screening myopia rates across different student groups from 2019 to 2023 were compared using the Chi square test. The trends in myopia rates were analyzed using the Chi square trend test. The Kruskal-Wallis H test was employed to compare AL/CR and its annual increment across groups. A linear mixed effects model was used to identify factors influencing AL/CR, and a time dependent Cox regression model was developed to predict the risk of myopia onset. Results: From 2019 to 2023, the screening myopia rates were 36.65%, 38.31%, 40.47%, 39.56%, and 39.76% for each respective year. Cohort analyses revealed Grade 5 girls had significantly greater AL/CR increments than boys ( Z =-2.05, P <0.05). Linear mixed models identified baseline AL/CR ( β =1.051, 95% CI =1.012-1.091), grade level ( β =0.040, 95% CI =0.038- 0.042 ), and first year AL/CR increment ( β =0.788, 95% CI =0.733-0.843) as primary determinants (all P <0.01). Boys showed slower AL/CR progression than girls ( β =-0.003, 95% CI =-0.005 to-0.001, P <0.01). The time dependent Cox model demonstrated that both baseline AL/CR ( Z =3.40) and its time varying effect ( Z =10.41) significantly predicted myopia risk(both P <0.01). The effect of AL/CR on myopia risk significantly increased with follow up time, and the growth rate exceeded a linear progression pattern. Conclusions AL/CR progression is primarily driven by baseline values and grade advancement, with slower progression in boys. Dynamic AL/CR monitoring outperforms baseline measurements in predicting myopia progression. Students with rapid AL/CR increments require early intervention.

Photoacoustic imaging (PAI), an emerging hybrid imaging modality, integrates the high spatial resolution of optical imaging with the deep-tissue imaging capability of ultrasound. Emerging evidence from recent studies in dental medicine has demonstrated the unique potential of PAI in screening, diagnosis, and therapeutic monitoring of oral pathologies, including periodontal diseases, oral cancers, and pulpal disorders. However, its clinical translation remains contingent upon addressing multiple technical barriers, particularly signal attenuation induced by optical scattering in biological tissues and limitations in real-time imaging efficiency. Therefore, investigating the advancements and challenges of PAI technology in the diagnosis of oral diseases will contribute to advancing further research and clinical applications, thereby providing practical support for improving the accuracy of early diagnosis and the efficacy of treatment for oral diseases.

Objective:To compare the efficacy of low-dose febuxostat and low-dose benzbromarone in lowering serum uric acid and their impact on liver function in male patients with renal underexcretion gout.Methods:This prospective cohort study enrolled 303 patients with renal underexcretion gout and normal baseline liver function. Participants were assigned to either the low-dose febuxostat group(20 mg qd) or the low-dose benzbromarone group(25 mg qd). A linear mixed-effects model was used to compare the uric acid target achievement rate(<360 μmol/L) and changes in liver enzyme levels between the two groups.Results:At week 4, the proportion of patients achieving the serum uric acid target(<360 μmol/L) was significantly higher in the benzbromarone group than that in the febuxostat group(64.2% vs 42.3%, P<0.001), with a trend toward greater efficacy at weeks 8 and 12. The incidence of alanine aminotransferase(ALT) or aspartate aminotransferase(AST) elevation above the upper limit was significantly higher in the febuxostat group compared to the benzbromarone group(35.2% vs 13.85%, P<0.001). After adjusting for baseline liver enzyme levels in the mixed-effects model, mean ALT and AST levels remained significantly higher in the febuxostat group than those in the benzbromarone group at weeks 4, 8, and 12( P<0.05). In the febuxostat group, ALT and AST levels significantly increased over time during weeks 0-4 and 4-8 ( P<0.001), peaking at week 8 followed by a decreasing trend. By week 12, the levels were not significantly different from baseline ( P>0.05). Whereas there was no significant difference at each follow-up time point in the benzbromarone group( P>0.05). Conclusions:In male patients with renal underexcretion gout, low-dose benzbromarone demonstrated superior urate-lowering efficacy and better hepatic safety compared to low-dose febuxostat.

Objective:To explore the core dimensions of adolescent anxiety and their relationship with parental rearing styles and perceived social support using network analysis.Methods:A total of 3 712 adolescents were in-vestigated.The Screen for Child Anxiety Related Emotional Disorders,the Short-form Egna Minnenav Barndoms Uppfostran for Chinese,and the Perceived Social Support Scale were used to assess the anxiety levels,parental rea-ring styles,and perceived social support.Network analysis and gender network comparison were conducted using R programming language.Results:The network analysis model showed that generalized anxiety and somatization/pan-ic anticipation had the highest Expected Influence of 1.21 and 1.12,which were the two core dimensions of adoles-cent anxiety levels.The affective warmth in parental rearing styles had a Bridge Expected Influence index of 0.34,making it a bridging node in the network.The network comparison result indicated that there were significant struc-tural gender differences in the adolescent anxiety-parenting style-perceived social support network(P＜0.05),but there was no significant gender difference in global strength(P＞0.05).Conclusion:Interventions targeting adoles-cent anxiety should prioritize generalized anxiety and somatization/panic.Emotional warmth in parenting serves as a bridge connecting adolescent anxiety with perceived levels of social support.

Severe combined immunodeficiency (SCID) represents a group of genetically heterogeneous disorders characterized by mutations that lead to profound defects in both humoral and cellular immunity. Transplacental maternal engraftment (TME) is a frequently observed complication in SCID. While most cases of SCID with TME exhibit no substantial impact on disease progression, a subset of patients may encounter diagnostic delays or therapeutic challenges due to TME interference. Furthermore, TME may predispose these individuals to graft-versus-host disease (GVHD) prior to hematopoietic stem cell transplantation, thereby increasing diagnostic complexity and treatment risks. This review systematically examines the etiology and clinical manifestations of SCID associated with TME, analyzes its implications for disease management, and evaluates current detection methodologies. The synthesized evidence provides a theoretical foundation for future research and offers potential insights into the clinical diagnosis and management of SCID associated with TME.

The cure rate of patients with classical Hodgkin’s lymphoma (cHL) has significantly improved and the mortality rate has decreased with the advancement of chemotherapy and radiotherapy, especially the application of combined radio-chemotherapy. However, some patients still face relapse or refractory issues, as well as the risk of death due to treatment-related adverse reaction. Treatment has fully entered the era of targeted therapy in recent years, with the deepening research on cHL. Novel drugs, represented by targeted CD30 antibody-drug conjugates and immune checkpoint inhibitors, have further improved the prognosis of patients with newly diagnosed and relapsed/refractory cHL. This study aims to determine the mechanism of achieving comprehensive optimization management of cHL in the new era of drugs, improve patient prognosis, enhance therapeutic efficacy, and reduce the occurence of adverse reactions.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.
