Objective　To evaluate the in vitro synergistic antimicrobial effect of allicin combined with imipenem on clinically isolated carbapenem-resistant Klebsiella pneumoniae (CRKP), providing a reference for further in vivo pharmacodynamic studies. Methods Twenty-two strains of CRKP were selected as experimental subjects based on clinical drug sensitivity results. Pulling assay together with carbapenem inhibition enhancement assay were leveraged to identify the high adherence and β-lactamase phenotypes of CRKP. The combined effect of allicin and imipenem was confirmed using the zero interaction potency (ZIP) method. The antimicrobial effects of allicin, imipenem, and their combination against CRKP were tested separately in vitro by agar paper diffusion method. The organic combination of allicin and imipenem was exploited for detecting the diameter of the CRKP inhibitory circle and minimal inhibitory concentration (MIC). The crystal violet semi-quantitative method was utilized to observe the effect of allicin combined with imipenem on CRKP biofilm formation. Results Among the 22 strains of CRKP, 6 strains exhibited high adhesion, accounting for 27.27%. The results of carbapenem inhibition enhancement demonstrated that all strains of CRKP were class A β-lactamase-producing. Allicin had a strong bactericidal effect on CRKP. According to the results of one-way ANOVA, the diameter of the circle of inhibition of allicin combined with imipenem (15.91±2.76)mm was significantly higher than that of the imipenem alone group (8.23±3.46) mm(F=46.39, P<0.001). The ZIP scoring and MIC methods confirmed that the combination of allicin and imipenem primarily exerted an additive effect. One-way ANOVA analysis of crystal violet absorbance values showed that compared to the control group (0.213±0.056), the total CRKP biofilm amount in the allicin combined with imipenem group was reduced (0.134±0.045) (F=3.211, P=0.045). Conclusions The results of bacterial inhibition experiments in vitro show that the combination of allicin and imipenem significantly increases the inhibitory ability of CRKP and inhibits biofilm formation effectively.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

Objective It explores the importance and effectiveness perception of 55 third-tier indicators in the cur-rent performance evaluation system.Methods From the perspective of those being assessed,it employs survey ques-tionnaires,Importance Performance Analysis(IPA),and focus group interviews to conduct research on the impor-tance and effectiveness perception.Results The overall perception of the importance and effectiveness of third-tier in-dicators is relatively high,and the performance evaluation indicator system can effectively assess the development level of level-3 public hospitals.There is a general discrepancy between the perception of importance and effective-ness.Some third-tier indicators face issues of insufficient perception of both importance and effectiveness.Conclu-sion Performance evaluation policy formulation based on the implementation of policies and after excluding the scores of indicators closely related to stakeholders can re-monitor and analyze indicators.This allows for the addition or removal of third-tier indicators,adjustment of indicator weights,optimization of indicator content,precision in mea-suring indicators,and improvement of the performance evaluation effectiveness of level-3 public hospitals.
