OBJECTIVE To provide a reference for pharmaceutical care in patients with hemorrhagic transformation after cerebral infarction complicated with atrial fibrillation. METHODS Clinical pharmacists participated in the treatment practice of a patient with hemorrhagic transformation after cerebral infarction complicated with atrial fibrillation. Because the patient had a hemorrhagic transformation after cerebral infarction after stent implantation and arterial thrombolysis, the clinical pharmacists recommended stopping antiplatelet drugs and giving plasma and cold precipitation; because D-dimer was significantly elevated, the clinical pharmacists recommended anticoagulant therapy with low-molecular heparin. Due to the patient’s recurrence of hemorrhagic transformation after cerebral infarction, the clinical pharmacists recommended discontinuing rivaroxaban and administering human prothrombin complex concentrate. RESULTS The physician adopted the clinical pharmacists’ recommendation. After treatment, the patient’s condition tended to improve steadily and was allowed to be discharged with medication. CONCLUSIONS The clinical pharmacists assessed the individualized risk and optimized the patient’s medication regimen by suggesting discontinuation of antiplatelet and anticoagulant drugs, carrying out pharmaceutical care such as coagulation index monitoring, determining the time and indications for restarting anticoagulation, and pharmaceutical monitoring, to ensure the safety and efficacy of the patient’s medication.

Objective:To obtain hepatitis B virus capsid-like particles (CLPs) displaying B-cell linear epitopes of SARS-CoV-2 spike protein and evaluate their immunogenicity.Methods:Four recombinant plasmids expressing fusion proteins (M1-HBc, S1-57-HBc, S14P5-HBc and S21P2-HBc) were constructed by separately replacing codon of alanine at position 80 of hepatitis B virus core protein (HBc) with four genes coding for four B-cell linear epitopes (M1, S1-57, S14P5 and S21P2). These four recombinant proteins were expressed in E. coli BL21 Star (DE3) strains. The expression products were identified using SDS-PAGE, Western blot and native agarose gel electrophoresis (NAGE). CLPs were purified by sucrose density gradient ultracentrifugation, verified for antigenicity by Western blot and used to immunize BALB/c mice. Serum antibody titers were detected by ELISA. Results:The recombinant fusion proteins M1-HBc and S1-57-HBc self-assembled into M1-CLP and S1-57-CLP. The titer of antibody against S1-57 polypeptide in S1-57-CLP-immunized mouse serum approached 1∶1 000 000.Conclusions:Hepatitis B virus CLPs displaying SARS-CoV-2 M1 or S1-57 linear epitopes are successfully expressed in a prokaryotic system and purified. S1-57-CLP has good immunogenicity. This study provides a new idea for the development of novel diagnostic reagents and vaccines for SARS-CoV-2.

Objective:We genetically modified our non-replicating vaccinia virus NTV to improve its immunogenicity.Methods:We constructed NTV-modified strain NTV-ΔF1L-C7L by homologous recombination of vaccinia virus based on CRISPR-Cas9 technology by inserting the C7L gene while deleting the F1L gene. The recombinant virus NTV-ΔF1L-C7L was then immunized with 10 7 PFU in BALB/c mice, and the levels of humoral and cellular immunity induced by NTV-ΔF1L-C7L were detected by ELISA and ELISpot method, respectively, and the levels of neutralizing antibodies were determined by the phage-reduced neutralization assay. Results:The PCR and western- blot identification proved that the F1L gene of the constructed NTV-modified strain NTV-ΔF1L-C7L was missing, while the C7L gene was inserted back in the region, and the C7L gene could be expressed normally, indicating that the recombinant virus was constructed correctly. After immunization of mice with NTV-ΔF1L-C7L, ELISA result showed that the recombinant virus NTV-ΔF1L-C7L induced a higher level of IgG antibody than NTV; ELISpot result also showed that the recombinant virus was able to induce a higher level of IFN-γ; and the result of plaque reduction neutralization test showed that the recombinant virus was able to induce a higher level of IFN-γ antibody than that of NTV.Conclusions:We correctly constructed the NTV gene-modified strain NTV-ΔF1L-C7L, which induced stronger humoral and cellular immunity compared with NTV, and provided reference data for the research and development of replacement products for smallpox or monkeypox vaccines.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
