Current status of bispecific antibody-mediated immunotherapy for hematologic malignancies / 中国输血杂志

Significant advances have been made in cancer immunotherapy recently, of which, bispecific antibodies (BsAbs), through bridging, redirecting and activating immune effector cells to kill cancer cells, are attracting increasing attention.Since the anti-CD19 and anti-CD3 BsAb, blinatumomab, was approved in 2014 by the FDA for the treatment of acute lymphoblastic leukemia, preclinical and clinical research with immune-cell-redirecting BsAbs have been fast growing in the area of hematologic malignancies. This review summarizes the current scientific and clinical investigation of BsAbs targeting different tumor-associated antigens from B lymphocytes, plasma cells and myeloid cells, covering three most common blood cancers, namely, lymphoma, multiple myeloma and leukemia. Further development for better therapeutic benefits and lower adverse events, are continuously being pursued, in particular, looking for more specific tumor antigens, optimizing antigen-antibody affinities, extending the half-life of BsAbs and redirecting different immune effector cells, whose breakthroughs and opportunities are soon to be delivered for the management of hematologic malignancies.

Nursing care of patients with obstructive sleep apnea syndrome during anesthesia / 中华护理杂志

Through analysis of the anatomic and physiological characteristics and the pathophysiological changes of 84 obstructive sleep apnea syndrome (OSAS) patients,the risks and key points of nursing care during general anesthesia were summarized,such as careful assessment of the patient situation,preparations of first aid materials and drugs,close observation and cooperation with the procedure of anesthesia,timely detecting and dealing with the abnormal changes during anesthesia.

Screening differentially expressed proteins of fibroblast-like synoviocytes in rheumatoid arthritis by 2-DE and MALDI-TOF-MS / 中华检验医学杂志

Objective To identify synovium-associated proteins of by analyzing proteome of FLS between RA patients and traumatic arthritis. Methods The total protein of FLS from 3 patients of RA and 6 normal controls were separated by 2-DE. The differentially expressed proteins were identified by MALDI-TOF-MS. Results The 2-DE image results showed that there were many proteins differentially expressed in FLS from RA and control. A total of 33 differential proteins that were up-regulated in RA as compared with controls were selected and 30 proteins including pyruvate kinase isozymes M1/M2, α-enolase, protein disulfide-isomerase A3 precursor, glutathione transferase, peroxiredoxin 1, ubiquitin-conjugating enzyme E2K, platelet-activating factor acetylhydrolase IB, dihydropyrimidinase-related protein 2, adenosine kinase, transaldolase, δ-δ-dienoyl-CoAisomerase, 26S protease regulatory subunit 6A, annexin All, tryptophanyl-tRNA synthetase isoform b, lamin-A/C, myomesin-1 isoform b, ruvB-like 1, actin-cytoplasmic 1, T-complex protein 1, stress-70 protein, mitochondrial precursor, α-crystallin B chain, 78 000 glucose-regulated protein, PSME4, SELENBP1 and so on. Conclusion The differentially expressed proteins are present in FLS from RA and control, which may be the synovium biomakers and involved in pathogenesis of RA.
