nstrate that WZYZW may ameliorate some GTW-induced BTB dysfunction, possibly by regulating proinflammatory cytokine levels. In vitro studies on the regulation of BTB permeability by WZYZW and its active components are further required.
Curcumae Rhizoma-Sparganii Rhizoma (CR-SR), an ancient and classical herbal couple, has been extensively used for tumor treatment in clinic of traditional Chinese medicines (TCMs).

The study aimed to uncover the anti-tumor active materials of CR-SR water decoction (CRSR=11) via an integrated approach of spectrum-effect relationship, molecular docking, and ADME evaluation.

The anti-tumor activities toward A549, HepG2, Hela, BGC-823, and MCF-7cells of the different polar elution fractions (DPEFs) of CR, SR, and CR-SR were determined by Cell Counting Kit-8 (CCK-8) assay. Likewise, the DPEFs' combinations of CR and SR were also tested. The chemical fingerprints of these fractions were profiled by HPLC. Cyclopamine concentration Meanwhile, HPLC-ESI-Q-TOF-MS/MS was applied for the identification of chemical components. The main effect-related compounds were screened out by spectrum-effect relationship and molecular docking method. The oral bioavailability and druggability of these active components were subsequently evaluated. Finally the active material basis of traditional Chinese herbal couples with a multi-technology integrated approach in practice, including chromatography, mass spectrometry, machine algorithm models, online databases, and in vitro cell experiments.
In summary, this study demonstrated that the multi-components of CR-SR contribute to its anti-tumor effects. It established a rapid and useful strategy to explore the active material basis of traditional Chinese herbal couples with a multi-technology integrated approach in practice, including chromatography, mass spectrometry, machine algorithm models, online databases, and in vitro cell experiments.
Comparisons between rilpivirine (RPV) and integrase strand transfer inhibitors (INSTIs) in antiretroviral therapy (ART)-naïve HIV-infected individuals are currently lacking. This study aimed to compare, in an observational cohort setting, the durability of treatment with RPV-based and INSTI-based first-line regimens.

Patients who started first-line ARTs based on RPV or INSTIs, with HIV-RNA <100000copies/mL and CD4 cell count > 200 cells/μL were included. The primary endpoint was the cumulative probability of treatment failure (TF=virological failure [confirmed HIV-RNA >50copies/mL] or discontinuation of the anchor drug in the regimen), as assessed by the Kaplan-Meier method. A multivariable Cox regression was used to control for potential confounding.

Of the 1991 included patients, 986 started ART with an RPV-based regimen and 1005 with an INSTIs-based regimen. The median (IQR) follow-up was 20 (10, 35) months. The cumulative 2-year probability of TF with RPV (9.1% [95% 7.2, 11.1]) was lower than that observed in the INSTIs group (16.6% [13.8, 19.4], P=0.0002) but not when compared with dolutegravir (DTG) alone. Starting ART with an INSTIs-based regimen vs. RPV was associated with a higher risk of TF after controlling for potential confounding factors (adjusted hazard ratio,AHR [95% CI] 1.64 [1.28, 2.10]; P < 0.001). The results were similar when restricting the analysis to single-tablet regimens, although the probability of virological success was higher for INSTIs and DTG.

In ART-naïve patients with low viral loads and high CD4 counts, the risk of treatment failure was lower in those who started RPV-based vs. INSTIs-based regimens other than DTG-based ones.

This study describes the first outbreak of XDR colistin- and carbapenem-resistant OXA-23-/NDM-1-producing Acinetobacter baumannii (CCRAB) in the European overseas territory of Reunion Island (France, Indian Ocean). Between April 2019 and June 2020, 13 patients admitted to the University Hospital of Reunion Island were involved in the outbreak, of whom eight were infected and six died. The first case was traced to a medical evacuation from Mayotte Island (Comoros archipelago). An epidemiological link could be established for 11 patients. All of the collected CCRAB isolates showed the same resistance profile and co-produced intrinsic β-lactamases OXA-69 and ADC-191, together with acquired carbapenem-hydrolysing β-lactamases OXA-23 and NDM-1. A mutation likely involved in colistin resistance was detected in the two-component system PmrAB (D82N in PmrA). All of the isolates were found to belong to STPas1/STOx231 clonal complex and were phylogenetically indistinguishable. Their further characterization by whole-genome sequence analyses (whole-genome multi-locus sequence typing, single nucleotide polymorphisms) provided hints about the transmission pathways. This study pleads for strict application of control and prevention measures in institutions where the risk of imported XDR bacteria is high.The human EGF receptor family plays pivotal roles in physiology and cancer, which contains four closely-related members HER1/EGFR, HER2, HER3 and HER4. Previously, it was found that the mitogen-inducible gene 6 (Mig6) protein is a negative regulator of EGFR and HER2 by using its S1 segment to bind at the kinase dimerization interface. However, it is still unclear whether the S1 segment can also effectively target HER3 and HER4? Here, we performed a systematic investigation to address this issue. The segment can bind to all the four HER kinases with a varying affinity and moderate selectivity; breaking of the segment into shorter hotspot peptides would largely impair the affinity and selectivity, indicating that the full-length sequence is required for the effective binding of S1 to these kinases. The hs2 peptide, which corresponds to the middle hotspot region of S1 segment, can partially retain the affinity to HER kinases, can moderately compete with S1 segment at the dimerization interfaces, and can mimic the biological function of Mig6 protein to suppress HER4+ esophageal cancer at cellular level.
