[Objective] To explore the effects of different methods on antibody detection through investigating the causes of cross-matching incompatible in a patient with gastric malignant tumor, and to establish flow cytometry protocol for confirming hemolytic transfusion reaction (HTR). [Methods] Antibodies in the patient's serum were identified by red blood cells (RBCs) blood grouping, antibody screening and identification, acid elution test and PEG enhancement test. To confirm HTR, patient RBCs, proximal and distal ends RBCs, separated by capillary centrifugation, were tested by direct antiglobulin test (DAT) and Jka antigen single label and double label flow cytometry. [Results] Routine serological technology revealed the presence of anti-C, e (titer:2) and anti-Jka (titer >1) in the patient’s serum. After separation using capillary centrifugation technology, both the proximal and distal DAT and Jka antigen tests were negative. Both DAT and Jka antigen positive red blood cells (0.21%, 6/6 327) were found in the patient's blood samples by flow cytometry. After separation of blood samples by capillary centrifugation, there were significantly more DAT and Jka antigen double-positive RBCs in the distal end (0.43%, 33/7 707) than in the proximal end (0.09%, 15/7 225). Two blood samples were screened from over 100 donor blood samples that are compatible with the patient's cross-matching, and the transfusion effect was favorable. [Conclusion] Serological methods combined with flow cytometry could improve the sensitivity of antibody detection, provide a more accurate basis for the diagnosis of HTRs, and guarantee the safety of blood transfusion.

Interfering hepatitis B virus (HBV) capsid assembly holds promise as a therapeutic approach for chronic hepatitis B (CHB). Novel anti-HBV agents are urgently needed to overcome drug resistance challenges, with targeted protein degradation (TPD) emerging as a hopeful strategy. Herein, we report the first degradation of HBV core protein (HBC), a multifunctional structural protein, using small-molecule degraders developed by hydrophobic tagging (HyT) technology. Structure-activity relationship (SAR) analysis identified compound HyT-S7, featuring an adamantyl group, exhibiting potent inhibitory activity (EC50 = 0.46 μmol/L, HepAD38 cells) and degradation ability (DC50 = 3.02 ± 0.54 μmol/L) in a dose- and time-dependent manner. Mechanistic studies demonstrated that the autophagy-lysosome pathway was a potential driver of HyT-S7-induced HBC degradation. Remarkably, HyT-S7 effectively degraded 11 drug-resistant mutants, including highly resistant strains P25G and T33N, to Phase III drug GLS4. Furthermore, cellular thermal shift assay, surface plasmon resonance assay, and molecular dynamics simulations revealed the precise mode of HyT-S7 binding to HBC with the adamantyl group potentially mimicking protein misfolding to facilitate HBC degradation. This first proof-of-concept study highlights the potential of HyT-mediated TPD in HBC as a promising avenue for discovering novel HBV and other antiviral agents with favorable drug resistance profiles.

BACKGROUND:This meta-analysis aimed to assess the efficacy of high-dose glucose-insulin-potassium(GIK)therapy on clinical outcomes in acute coronary syndrome(ACS)patients receiving reperfusion therapy. METHODS:We searched the PubMed,Web of Science,MEDLINE,Embase,and Cochrane Library databases from inception to April 26,2022,for randomized controlled trials(RCTs)that compared high-dose GIK and placebos in ACS patients receiving reperfusion therapy.The primary endpoint was major adverse cardiovascular events(MACEs). RESULTS:Eleven RCTs with 884 patients were ultimately included.Compared with placebos,high-dose GIK markedly reduced MACEs(risk ratio[RR]0.57,95%confidence interval[95%CI]:0.35 to 0.94,P=0.03)and the risk of heart failure(RR 0.48,95%CI:0.25 to 0.95,P=0.04)and improved the left ventricular ejection fraction(LVEF)(mean difference[MD]2.12,95%CI:0.40 to 3.92,P=0.02)at 6 months.However,no difference was observed in all-cause mortality at 30 d or 1 year.Additionally,high-dose GIK was significantly associated with increased incidences of phlebitis(RR 4.78,95%CI:1.36 to 16.76,P=0.01),hyperglycemia(RR 9.06,95%CI:1.74 to 47.29,P=0.009)and hypoglycemia(RR 6.50,95%CI:1.28 to 33.01,P=0.02)but not reinfarction,hyperkalemia or secondary reperfusion.In terms of oxidative stress-lowering function,high-dose GIK markedly reduced superoxide dismutase(SOD)activity but not glutathione peroxidase(GSH-Px)or catalase(CAT)activity. CONCLUSION:Patients with ACS receiving reperfusion therapy exhibited a reduction in MACEs and good oxidative stress-lowering efficacy in response to high-dose GIK.Moreover,with a higher incidence of complications such as phlebitis,hyperglycemia,and hypoglycemia.Furthermore,there were no observed survival benefits associated with high-dose GIK.More trials with long-term follow-up are still needed.
