ObjectiveThis paper aims to investigate the efficacy and related actions of Guizhi Fulingwan in intervening in the mice with colitis-associated colon cancer （CAC） based on the immunosuppressive microenvironment associated with myeloid-derived suppressor cells （MDSCs）. MethodsSixty male C57BL/6 mice were randomly assigned to a blank group， a model group， an aspirin group （0.04 g·kg^-1）， and low-， medium-， and high-dose Guizhi Fulingwan groups （4.87， 9.75， and 19.50 g·kg^-1）， with ten mice per group. The CAC mouse model was established via combined induction of azoxymethane （AOM）/dextran sulphate sodium （DSS）. Drug intervention commenced in week five， with continuous intragastric administration for nine weeks. The food intake， body weight， fecal characteristics， and haematochezia were observed and recorded， and disease activity index （DAI） scores were calculated according to scoring criteria. Hematoxylin and eosin （HE） staining was used to observe the histopathological changes in the colon tissues of the mice. Immunohistochemistry was used to determine proliferating cell nuclear antigen-67 （Ki67） expression in the colon tissues， and enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） in the serum of the mice. Flow cytometry was employed to determine the proportion levels of MDSCs， CD4⁺ T cells， and CD8⁺ T cells in the spleen tissues of the mice. The mRNA expressions of MDSC-associated effector molecules， including arginase 1 （Arg1） and inducible nitric oxide synthase （iNOS）， were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. After that， an in vitro co-culture model of MDSCs and CD8⁺ T cells was established， and drug-containing serum of Guizhi Fulingwan was used for intervention. The Flow cytometry was employed to assess the effects of drug-containing serum of Guizhi Fulingwan with different concentrations on the levels of reactive oxygen species （ROS） and iNOS in MDSCs and the proliferation of CD8⁺ T cells. The levels of granzyme B （GZMB） and interferon-γ （IFN-γ） in cell supernatant were detected by ELISA. ResultsCompared with those in the control group， the mice in the model group exhibited significantly reduced body weight， elevated DAI scores， shortened colon length （P<0.01）， increased number of tumors and Ki67 expression （P<0.01）， and significantly elevated contents of IL-6， IL-1β， and TNF-α in the serum （P<0.01）. Significant increases in the number of MDSCs were observed in mouse spleens， alongside marked reductions in the levels of CD4⁺ T and CD8⁺ T cells （P<0.01）. Furthermore， the mRNA expressions of MDSC function-associated effector molecules Arg1 and iNOS were significantly upregulated （P<0.01）. Compared with those in the model group， the mice in the middle-dose Guizhi Fulingwan group exhibited increased body weight and significantly decreased DAI scores （P<0.05， P<0.01）. The mice in the middle- and high-dose Guizhi Fulingwan groups exhibited significantly improved colon shortening， significantly decreased number of tumors and Ki67 expression （P<0.05， P<0.01）， and significantly decreased contents of IL-6， IL-1β， and TNF-α in the serum （P<0.05， P<0.01）. Furthermore， administration of Guizhi Fulingwan markedly reduced MDSC infiltration in the spleen of the mice， with different degrees of increase in the levels of both CD4⁺ T and CD8⁺ T cells （P<0.05， P<0.01）， alongside significant decreases in the mRNA expressions of Arg1 and iNOS （P<0.05， P<0.01）. In vitro cell co-culture shows that administration of drug-containing serum of Guizhi Fulingwan significantly decreases the activity levels of ROS and iNOS in MDSCs and promotes the proliferation of CD8⁺ T cells and the secretion of GZMB and IFN-γ （P<0.05， P<0.01）. ConclusionGuizhi Fulingwan can reduce pro-inflammatory cytokine secretion and inhibit tumor proliferation in the colon tissues of CAC mice. Its potential mechanism may involve reducing MDSC infiltration， enhancing effector T cells， particularly CD8⁺ T cell response， and improving the tumor immunosuppressive microenvironment.

Objective To investigate the effect of Huangqi Shengmai Yin(HSY)on myocardial fibrosis in rats with acute myocardial infarction(AMI)by adjusting P2X purinoceptor 7(P2X7R)/NOD-like receptor protein 3(NLRP3)pathway.Methods Sixty rats were divied into a sham operation group and model group(5 groups),with 10 rats in each group.The AMI rat model was constructed by ligating the left anterior descending branch and randomly grouped into AMI group,the HSY-low group(intragastric administration of 1.6 ml/kg HSY),the HSY group(intragastric administration of 6.2 ml/kg HSY),the compound miltiorhiza group(intragastric administration of 300 mg/kg),and the HSY-high+P2X7R agonist-ATP group(intragastric administration of 6.2 ml/kg HSY,and tail vein administration of 10 mmol/L ATP).After the intervention,cardiac function,myocardial injury and inflammatory factor markers were detected.The tissue sections were prepared to examine pathological changes,myocardial fibrosis,type Ⅰ and type Ⅲ collagen(COL1A1,COL3A1).Western blotting was performed to detecte the protein expression of P2X7R,NLRP3,tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and the expression of activated Caspase-1.Results Compared with the sham surgery group,the AMI group showed an increase in the left ventricular end diastolic diameter(LVEDD),the coatent of brain natriuretic peptide(BNP)and cardiac troponin I(cTn I),fibrosis volume fraction,the positive expression of COL1A1,COL3A1,TNF-α,IL-1β,P2X7R,NLRP3,and activated Caspase-1 proteins(P＜0.05),and a decrease in left ventricular ejection fraction(LVEF)(P＜0.05).The HSY-low group,HSY-high groups,and compound miltiorhiza group showed a decrease in LVEDD,the content of BNP and cTn I,fibrosis volume fraction,the positive expression of COL1A1 and COL3A1,TNF-α,IL-1β,P2X7R,NLRP3,and activated Caspase-1 proteins(P＜0.05),and an increase in LVEF than these in the AMI group(P＜0.05).The HSY-high+ATP group showed an increase in LVEDD,the content of BNP,cTn I,fibrosis volume fraction,the positive expression of COL1A1 and COL3A1,TNF-α,IL-1β,P2X7R,NLRP3,and activated Caspase-1 proteins(P＜0.05),and a decrease in LVEF than those in the HSY-high group(P＜0.05).Conclusion HSY inhibits P2X7R/NLRP3 pathway to alleviate myocardial fibrosis in AMI rats.

Objective The aim of this study is to examine the Chinese version of Visual Prostate Symptom Score(CVPSS)and the International Prostate Symptom Score(IPSS)in the assessment of lower urinary tract symptoms in BPH pa-tients.Methods By using convenient sampling,inpatients in the urology department of a tertiary grade A hospital in Shanghai were selected as the survey subjects from March 2023 to March 2024.The lower urinary tract symptoms of the patients were eval-uated using the self-designed general information questionnaire.And the CVPSS and IPSS with their urine flow rate were meas-ured.A comparative analysis was conducted from aspects such as internal consistency,correlation of item scores,completion time of the scale,and assistance rate.Results A total of 246 patients with BPH were recruited.The total score and life quality score were 13.93±3.55 and 4.23±1.02 by CVPSS.And the total score and life quality by IPSS was 18.33±7.55 and 4.36±1.02,respectively.The Cronbach's α coefficient were 0.761 and 0.787,respectively.The time taken on CVPSS was less than that on IPSS(P＜0.01).And the rate of needing assistance was 23.58％for CVPSS,which was significantly lower than that(65.24％)for IPSS.Conclusion CVPSS is significantly correlated with the corresponding items and total scores of IPSS,as well as the quality of life.Moreover,it takes less time and can be used as a simple and effective self-assessment tool for lower urinary tract symptoms in elderly BPH patients with lower education levels.It reduces the burden of medical staffs as well.

Purpose: Considering the high disease burden and unique features of Asian patients with breast cancer (BC), it is essential to have a comprehensive view of genetic characteristics in this population. An institutional targeted sequencing platform was developed through the Korea Research-Driven Hospitals project and was incorporated into clinical practice. This study explores the use of targeted next-generation sequencing (NGS) and its outcomes in patients with advanced/metastatic BC in the real world. Materials and Methods: We reviewed the results of NGS tests administered to BC patients using a customized sequencing platform—FiRST Cancer Panel (FCP)—over 7 years. We systematically described clinical translation of FCP for precise diagnostics, personalized therapeutic strategies, and unraveling disease pathogenesis. Results: NGS tests were conducted on 548 samples from 522 patients with BC. Ninety-seven point six percentage of tested samples harbored at least one pathogenic alteration. The common alterations included mutations in TP53 (56.2%), PIK3CA (31.2%), GATA3 (13.8%), BRCA2 (10.2%), and amplifications of CCND1 (10.8%), FGF19 (10.0%), and ERBB2 (9.5%). NGS analysis of ERBB2 amplification correlated well with human epidermal growth factor receptor 2 immunohistochemistry and in situ hybridization. RNA panel analyses found potentially actionable and prognostic fusion genes. FCP effectively screened for potentially germline pathogenic/likely pathogenic mutation. Ten point three percent of BC patients received matched therapy guided by NGS, resulting in a significant overall survival advantage (p=0.022), especially for metastatic BCs. Conclusion Clinical NGS provided multifaceted benefits, deepening our understanding of the disease, improving diagnostic precision, and paving the way for targeted therapies. The concrete advantages of FCP highlight the importance of multi-gene testing for BC, especially for metastatic conditions.

Hepatocellular carcinoma (HCC) is an aggressive primary liver malignancy often diagnosed at an advanced stage, resulting in a poor prognosis. Accurate risk stratification and early detection of HCC are critical unmet needs for improving outcomes. Several blood-based biomarkers and imaging tests are available for early detection, prediction, and monitoring of HCC. However, serum protein biomarkers such as alpha-fetoprotein have shown relatively low sensitivity, leading to inaccurate performance. Imaging studies also face limitations related to suboptimal accuracy, high cost, and limited implementation. Recently, liquid biopsy techniques have gained attention for addressing these unmet needs. Liquid biopsy is non-invasive and provides more objective readouts, requiring less reliance on healthcare professional’s skills compared to imaging. Circulating tumor cells, cell-free DNA, and extracellular vesicles are targeted in liquid biopsies as novel biomarkers for HCC. Despite their potential, there are debates regarding the role of these novel biomarkers in the HCC care continuum. This review article aims to discuss the technical challenges, recent technical advancements, advantages and disadvantages of these liquid biopsies, as well as their current clinical application and future directions of liquid biopsy in HCC.
