Objective:To evaluate the diagnostic performance of the Vesical Imaging-Reporting and Data System(VI-RADS)based on multiparametric magnetic resonance imaging(mp-MRI)for muscle-invasive bladder cancer(MIBC).Methods:A systematic search was conducted in PubMed,Web of Science,and Embase databases for studies published between September 2018 and December 2023 that investigated the use of VI-RADS for diagnosing MIBC. Inclusion criteria were studies utilizing mp-MRI-based VI-RADS scoring to determine MIBC. Exclusion criteria were studies with fewer than 10 patients,overlapping study populations,or those failing to assess the diagnostic performance of VI-RADS for MIBC. After quality assessment,RevMan 5.4 and Stata 15.1 were used to calculate pooled sensitivity and specificity,generate forest plots and summary receiver operating characteristic(SROC)curves,and determine the area under the curve(AUC). Publication bias was assessed using Deeks funnel plot. Heterogeneity was evaluated using the I2 statistic,with meta-regression and subgroup analyses to explore its sources. Results:Twenty-nine studies involving 3 577 patients were included. At a VI-RADS cutoff of 3,the pooled sensitivity and specificity for MIBC diagnosis were 93%(95%CI 0.90-0.95)and 82%(95%CI 0.76-0.88),respectively. At a cutoff of 4,these values were 83%(95%CI 0.78-0.87)and 93%(95%CI 0.90-0.95). The hierarchical SROC(HSROC)AUCs were 0.95 and 0.94 for cutoffs of 3 and 4,respectively. Subgroup and meta-regression analyses revealed that at a cutoff of 3,patient sample size,study design,MRI field strength,number of radiologists,surgical approach,and DWI/DCE imaging planes contributed to sensitivity heterogeneity( P < 0.05). All factors except study design and DWI plane were sources of specificity heterogeneity( P < 0.05). At a cutoff of 4,all factors significantly influenced heterogeneity in both sensitivity and specificity( P < 0.05). Meta-regression confirmed that both cutoffs(3 and 4)were significant sources of heterogeneity( P < 0.05). Conclusions:VI-RADS demonstrates excellent diagnostic performance for MIBC at both cutoffs(3 and 4),with VI-RADS ≥ 3 showing superior sensitivity and VI-RADS ≥ 4 offering higher specificity. The cutoff of 3 provides better overall diagnostic efficacy.

OBJECTIVE:
To investigate the inhibitory effect of Tanreqing Injection (TRQ) on the activation of nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3) inflammasome in macrophages infected with influenza A virus and the underlying mechanism based on mitophagy pathway.
METHODS:
The inflammatory model of murine macrophage J774A.1 induced by influenza A virus [strain A/Puerto Rico/8/1934 (H1N1), PR8] was constructed and treated by TRQ, while the mitochondria-targeted antioxidant Mito-TEMPO and autophagy specific inhibitor 3-methyladenine (3-MA) were used as controls to intensively study the anti-inflammatory mechanism of TRQ based on mitophagy-mitochondrial reactive oxygen species (mtROS)-NLRP3 inflammasome pathway. The levels of NLRP3, Caspase-1 p20, microtubule-associated protein 1 light chain 3 II (LC3II) and P62 proteins were measured by Western blot. The release of interleukin-1β (IL-1β) was tested by enzyme linked immunosorbent assay, the mtROS level was detected by flow cytometry, and the immunofluorescence and co-localization of LC3 and mitochondria were observed under confocal laser scanning microscopy.
RESULTS:
Similar to the effect of Mito-TEMPO and contrary to the results of 3-MA treatment, TRQ could significantly reduce the expressions of NLRP3, Caspase-1 p20, and autophagy adaptor P62, promote the expression of autophagy marker LC3II, enhance the mitochondrial fluorescence intensity, and inhibit the release of mtROS and IL-1β (all P<0.01). Moreover, LC3 was co-localized with mitochondria, confirming the type of mitophagy.
CONCLUSION
TRQ could reduce the level of mtROS by promoting mitophagy in macrophages infected with influenza A virus, thus inhibiting the activation of NLRP3 inflammasome and the release of IL-1β, and attenuating the inflammatory response.

Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

Aim To investigate the effect of N6-methy-ladenosine(m6A)demethylase ALKBH5 on the prolif-eration and migration of cardiac fibroblasts(CFs)in-duced by high glucose.Methods Primary CFs were isolated from neonatal mouse hearts and identified u-sing optical and confocal microscopy.Cell activation was induced using a high-glucose medium(33 mmol·L-1 glucose).An ALKBH5 overexpression model was established by transfecting CFs with an ALKBH5 ex-pression vector in a high-glucose medium.The expres-sion of ALKBH5 in CFs was assessed through immuno-fluorescence staining,Western blot and RT-qPCR.Changes in m6A levels were evaluated using Dot blot a-nalysis.Additionally,Alterations in the expression of proliferating cell nuclear antigen(PCNA)and collagenⅠ,a pivotal fibrosis indicator,were measured using Western blot.The proliferation and migration ability of CFs were assessed through EdU staining and Transwell migration assay,respectively.Results Following treatment with high glucose,the expression of ALKBH5 in CFs notably decreased,while m6A level increased.This was accompanied by a significant increase in the expression of the proliferation marker PCNA and the fi-brosis marker collagen Ⅰ.Additionally,there was a sig-nificant improvement in the ability of proliferation and migration.Overexpression of ALKBH5 resulted in a significant decrease in the expressions of PCNA and collagen Ⅰ,leading to the inhibition of both proliferation and migration in CFs.Conclusion Overexpression of ALKBH5 suppresses the expression of PCNA and colla-gen Ⅰ,consequently reducing the proliferation and mi-gration of CFs,potentially through m6A methylation modification.

Objective:To investigate the action mechanism of formononetin(FN)in regulating T helper type 1(Th1)cell dif-ferentiation and macrophage polarization through JAK/STAT signaling pathways in a mouse model of experimental autoimmune prostati-tis(EAP).Methods:Forty non-obese diabetic(NOD)male mice were randomly divided into four groups:normal control,EAP model control,low-dose FN(LFN,50 mg/kg)and high-dose FN(HFN,100 mg/kg).The EAP model was established in the latter three groups by subcutaneous injection of prostate antigens(PAgs)combined with complete Freund's adjuvant(CFA).After modeling,the mice in the LFN and HFN groups were treated intragastrically with FN at 50 and 100 mg/kg/d,respectively,and those in the nor-mal and model controls groups with carboxymethylcellulose sodium(CMC-Na).At 42 days after treatment,all the animals were killed and relevant tissues collected for observation of the pathological changes in the prostate tissue by HE staining,detection of Th1 cell dif-ferentiation and macrophage polarization in the prostate by immunofluorescence double staining(labeling CD4 and interferon-γ[IFN-γ],inducible nitric oxide synthase[iNOS]and CD206),measurement of the ratio of Th1 cells/macrophages in the spleen by flow cy-tometry and the levels of IFN-γ and tumor necrosis factor-α(TNF-α)in the serum by ELISA,and determination of the expressions of phosphorylated(p)-Janus kinase(JAK)1,JAK1,p-JAK2,JAK2,p-signal transducer and activator of transcription(STAT1)in the prostate tissue by Western blot.Results:Compared with the model controls,the mice treated with low-and high-dose FN exhibited more orderly arrangement of glandular epithelial cells,significantly reduced prostatic tissue inflammation scores(P<0.05),and de-creased proportion of Th1 cells and expression of M1 macrophages(P<0.05),but increased expression of M2 macrophages in the prostate and spleen tissues(P<0.05).Besides,the levels of inflammatory cytokines IFN-γ(P<0.05)and TNF-α(P<0.05)in the serum of the mice in the LFN and HFN groups were remarkably reduced,and so were the ratios of p-JAK1/JAK1,p-JAK2/JAK2 and p-STAT1/STAT1 in the prostate tissues at the molecular level(P<0.05),indicating the therapeutic effect of FN on EAP by regu-lating JAK/STAT signaling pathways,promoting inflammation resolution,and restoring immune balance.Conclusion:FN alleviates EAP by inhibiting JAK/STAT signaling pathways and regulating Th1 cell differentiation and macrophage polarization.

Objective:To evaluate the diagnostic performance of the Vesical Imaging-Reporting and Data System(VI-RADS)based on multiparametric magnetic resonance imaging(mp-MRI)for muscle-invasive bladder cancer(MIBC).Methods:A systematic search was conducted in PubMed,Web of Science,and Embase databases for studies published between September 2018 and December 2023 that investigated the use of VI-RADS for diagnosing MIBC. Inclusion criteria were studies utilizing mp-MRI-based VI-RADS scoring to determine MIBC. Exclusion criteria were studies with fewer than 10 patients,overlapping study populations,or those failing to assess the diagnostic performance of VI-RADS for MIBC. After quality assessment,RevMan 5.4 and Stata 15.1 were used to calculate pooled sensitivity and specificity,generate forest plots and summary receiver operating characteristic(SROC)curves,and determine the area under the curve(AUC). Publication bias was assessed using Deeks funnel plot. Heterogeneity was evaluated using the I2 statistic,with meta-regression and subgroup analyses to explore its sources. Results:Twenty-nine studies involving 3 577 patients were included. At a VI-RADS cutoff of 3,the pooled sensitivity and specificity for MIBC diagnosis were 93%(95%CI 0.90-0.95)and 82%(95%CI 0.76-0.88),respectively. At a cutoff of 4,these values were 83%(95%CI 0.78-0.87)and 93%(95%CI 0.90-0.95). The hierarchical SROC(HSROC)AUCs were 0.95 and 0.94 for cutoffs of 3 and 4,respectively. Subgroup and meta-regression analyses revealed that at a cutoff of 3,patient sample size,study design,MRI field strength,number of radiologists,surgical approach,and DWI/DCE imaging planes contributed to sensitivity heterogeneity( P < 0.05). All factors except study design and DWI plane were sources of specificity heterogeneity( P < 0.05). At a cutoff of 4,all factors significantly influenced heterogeneity in both sensitivity and specificity( P < 0.05). Meta-regression confirmed that both cutoffs(3 and 4)were significant sources of heterogeneity( P < 0.05). Conclusions:VI-RADS demonstrates excellent diagnostic performance for MIBC at both cutoffs(3 and 4),with VI-RADS ≥ 3 showing superior sensitivity and VI-RADS ≥ 4 offering higher specificity. The cutoff of 3 provides better overall diagnostic efficacy.
