Interference of CD38 monoclonal antibody in blood compatibility testing and its countermeasures: A general consensus among experts / 中国输血杂志

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.

Thyroid stimulating hormone levels predict short-term outcome after intravenous thrombolysis in patients with acute ischemic stroke / 国际脑血管病杂志

Objective:To investigate the predictive value of thyroid stimulating hormone (TSH) levels on short-term outcome after intravenous thrombolysis in patients with acute ischemic stroke.Methods:From January 2016 to June 2019, patients with acute ischemic stroke receiving intravenous alteplase in the Department of Neurology, Jinshan Branch of Shanghai Sixth People's Hospital were enrolled retrospectively. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of baseline neurological deficits. The modified Rankin Scale was used for short-term outcome evaluation at 14 d after onset. 0-2 was defined as good outcome and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factors for poor short-term outcomes. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of thyroid stimulating hormone on short-term prognosis of patients with acute ischemic stroke. Results:A total of 90 patients with acute ischemic stroke received intravenous thrombolysis were enrolled. Their age was 70.08±9.76 years, and 49 (54.44%) were male. The median NIHSS score before thrombolysis was 11.00 (interquartile range, 5.00-16.00). Forty-eight patients (53.33%) had good short-term outcomes, and 42 (46.67%) had poor short-term outcomes. Multivariate logistic regression analysis showed that after adjusting for confounding factors, severe neurological deficits at admission (severe stroke vs. mild stroke: odds ratio [ OR] 9.390, 95% confidence interval [ CI] 2.015-43.764; P=0.004) and low levels of TSH (the 2nd quartile vs. 4th quartile: OR 5.999, 95% CI 1.038-34.657, P=0.045; the 1st quartile vs.4th quartile: OR 6.525, 95% CI 1.107-38.469, P=0.038) were the independent predictors of poor short-term outcome after intravenous thrombolysis in patients with acute ischemic stroke. The ROC curve analysis showed that the area under the curve of TSH for predicting poor outcomes was 0.682 (95% CI 0.572-0.793; P=0.003). The best cutoff value was 1.695 mIU/L, the sensitivity was 76.19%, and the specificity was 60.42%. Conclusion:The decreased serum TSH is an independent predictor of poor short-term outcome after intravenous thrombolysis in patients with acute ischemic stroke.

Integrin β1 in Adipose-Derived Stem Cells Accelerates Wound Healing via Activating PI3K/AKT Pathway

Background@#This study aims to investigate the effect of integrin β1 on wound healing induced by adipose-derived stem cells (ADSCs), as well as the corresponding mechanism. @*Methods@#Integrin β1 was overexpressed in ADSCs. Thereafter, flow cytometry and transwell chambers technology were used to measure the endothelial-like differentiation (CD31 as a biomarker of endothelial cell) and cell migration, respectively. Western blot was used to detect the activation of PI3K/AKT, NF-κB and ERK signaling pathways. The effects of integrin β1 overexpression on healing time, healing rate and fibroblast number were further evaluated in the rat models of chronic refractory wound. @*Results@#The overexpression of integrin β1 increased CD31+ endothelial-like cells (about 3.6-fold), promoted cell migration (about 1.9-fold) and enhanced the activation of PI3K (p-PI3K; about 2.1-fold) and AKT (p-AKT; about 2.2-fold). These effects were all weakened when PI3K/AKT pathway was inhibited by LY294002 treatment. In addition, the experiments in rat wound models showed that integrin β1 overexpression obviously shortened healing time (approximately 0.41-fold), increased healing rate (about 2.7-fold, 2.8-fold and 1.6-fold at day 7, 14 and 21) and increased the number of fibroblasts (approximately 3.1-fold at day 21). All of the above differences were statistically significant (p < 0.05). @*Conclusion@#Integrin β1 can promote the migration and endothelial-like differentiation of ADSCs by activating PI3K/AKT pathway and then enhance the function of ADSCs in promoting wound healing.

Penicillinase-producing Neisseria gonorrhoeae and its blaTEM-135 gene variants at several gonococcal antimicrobial surveillance sites in China：an epidemiological study / 中华皮肤科杂志

Objective To determine the prevalence of penicillinase-producing Neisseria gonorrhoeae(PPNG) and the distribution of blaTEM-135 gene variants in PPNG at several gonococcal antimicrobial surveillance sites in China, to compare N. gonorrhoeae multi-antigen sequence typing(NG-MAST)types of PPNG and its blaTEM-135 gene variants, and to assess the difference and association in NG-MAST types of blaTEM-135 gene variants among different regions. Methods A total of 572 N. gonorrhoeae isolates were collected at 6 gonococcal antimicrobial surveillance sites from Jiangsu, Shanghai, Zhejiang, Tianjin, Guangdong and Guangxi in 2012. After isolation, purification, and identification, cefalotin paper discs were used for detection of PPNG. DNA was extracted by QIAxtractor DX kits after cultivation of the PPNG strains. Then, mismatch amplification mutation assay (MAMA) PCR was performed to identify blaTEM-135 variants, and NG-MAST analysis to determine N. gonorrhoeae genotypes. Results Among the 572 N. gonorrhoeae strains, 38.1%(218/572) were identified as PPNG, and of the PPNG strains, 52.3% (114/218) were blaTEM-135 variants. The detection rate of PPNG at these surveillance sites from high to low was as follows: 51.7% (45/87, Zhejiang), 45.6%(36/79, Shanghai), 38.0% (78/205, Guangdong), 37.5% (12/32, Guangxi), 31.2% (24/77, Jiangsu) and 25.0%(23/92, Tianjin), and that of blaTEM-135 variants was as follows: 68.9%(31/45, Zhejiang), 58.3%(14/24, Jiangsu), 50.0%(39/78, Guangdong), 47.2%(17/36, Shanghai), 39.1%(9/23, Tianjin)and 33.3%(4/12, Guangxi). NG-MAST analysis showed that the ST2318, ST1768, ST1866, ST1053 and ST8726 types predominated among these bla TEM-135 variants, and a strong correlation was found between blaTEM-135 variants and some NG-MAST types, such as ST1768, ST1053 and ST8726 types. The distribution of NG-MAST types was significantly different between the surveillance site in Tianjin (in the Northern part of China) and the other sites (in the Southern part of China), but highly similar among the surveillance sites in Jiangsu, Zhejiang and Shanghai regions. Conclusions There is a high prevalence of PPNG and its blaTEM-135 variants at several gonococcal antimicrobial surveillance sites in China, with significant differences in NG-MAST genotype distribution of PPNG and its blaTEM-135 variants among different regions.
