ABSTRACT

@#To compare the effects of endogenous 3-nitrotyrosine and non-natural 4-nitrophenylalanine in PD-L1 vaccine on the differentiation of T cell subsets, two immunogenic amino acids were introduced into the same site of PD-L1 vaccine. Two PD-L1 mutants with 3-nitrotyrosine and 4-nitrophenylalanine were obtained, respectively, using genetic code expansion technology. Mice were immunized with these two mutants, and their effects on the differentiation of T cell subsets in spleen were analyzed. The results of flow cytometry showed that the introduction of 4-nitrophenylalanine in PD-L1 vaccine could promote the polarization of Th1 cells while reducing the proportion of Treg cells; the introduction of 3-nitrotyrosine had no effect on the polarization of Th1 cells, while significantly increasing the proportion of Treg and Th17 cells. The introduction of both into PD-L1 vaccine could promote the response of CD8+ T cells in spleen, and the response of PD-L1 mutant containing 4-nitrophenylalanine was stronger. In summary, the non-natural 4-nitrophenylalanine is more suitable for the design of tumor vaccines as compared with endogenous 3-nitrotyrosine.

ABSTRACT

Objective:To explore the expression level of serum exosomal miR-223-3p in patients with multiple myeloma (MM) and evaluate its clinical application.Methods:A case-control study was performed. Serum samples were collected from the Department of Hematology, Affiliated Hospital of Nantong University from March 2018 to August 2019, including 68 newly diagnosed untreated MM patients (16 in stage Ⅰ, 22 in stage Ⅱ and 30 in stage Ⅲ), 56 healthy controls and 30 patients with recurrent MM in the same period, and follow-up patients who underwent chemotherapy for 3 months after initial diagnosis. Serum exosomes were purified and identified, RNA was extracted, and RT-qPCR was performed to compare the levels of miR-223-3p in serum exosomes between the groups. The correlation between exosomal miR-223-3p levels and clinical pathological data was analyzed, and the diagnostic efficacy was evaluated by ROC curve.Results:Compared with healthy controls (0.92±0.29), the expression level of serum exosomal miR-223-3p in newly diagnosed MM patients (0.52±0.23) decreased significantly ( U=565, P<0.000 1). According to the international staging system of MM, the expression level of serum exosomal miR-223-3p in patients with stage Ⅰ(0.67±0.26) was significantly higher than that in patients with stage Ⅱ (0.47±0.21) and Ⅲ (0.48±0.19) ( U values were 96.5 and 138 respectively, P were all less than 0.05). In addition, the expression level of serum exosomal miR-223-3p increased after 3 months of chemotherapy (0.69±0.19) compared with that before chemotherapy (0.50±0.22) ( U=228.5, P=0.000 8). Compared with the healthy control group (0.84±0.21), the expression level of serum exosomal miR-223-3p in recurrent MM patients (0.65±0.18) was also decreased ( U=244, P=0.002). At the same time, the expression level of serum exosomal miR-223-3p may be related to the low expression of albumin ( U=411.5, P=0.043 1) and bone damage ( U=309, P=0.001). The ROC curves showed that the AUC of serum exosomal miR-223-3p in the diagnosis of MM was 0.853, which was higher than that of β 2-microglobulin (β 2-MG) (AUC=0.805) and albumin (AUC=0.743). The AUC of the three combined detection was 0.918. Conclusions:Serum exosomal miR-223-3p can be used as a potential marker for auxiliary diagnosis of MM, and its combination with β 2-MG and albumin can improve the diagnostic efficacy of MM.

ABSTRACT

Objective To investigate the clinical diagnostic value of circulating tumor cells (CTCs)and circulating cell-free DNA (cfDNA) in peripheral blood samples in breast cancer. Methods From July 2017 to April 2018, 47 patients with BMC (7 in stage Ⅱ, 19 in stage Ⅲ and 21 in stage Ⅳ), 24 patients with benign breast diseases and 28 healthy people were selected. After collecting peripheral blood samples, serum and blood cells were separated. The size-based high-throughput microfluidic chip was used to capture CTCs. The real-time fluorescent quantitative PCR based on Alu sequence was used to detect the length of cfDNA(247 bp, 115 bp)in the serum, and the ratio of amplified products of long and short fragments was used as the index of DNA integrity. The Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between the groups and analyze the relationship between CTCs and cfDNA and clinical parameters of breast cancer. The ROC curve was drawn and the area under the curve (AUC) was used to evaluate the feasibility of blood cell CTCs and plasma cfDNA detection as diagnostic criteria. Results The CTCs and cfDNA of 47 BMC patients were analyzed. The CTCs and cfDNA integrity index (Alu 247/115) of BMC patients were significantly higher than those of physical examination patients[(13.98± 12.36)cells / ml vs (1.14 ± 1.35) cells / ml; 0.7687 ± 0.3868 vs 0.5094 ± 0.2456], and the difference was statistically significant(the U value was 126.5,359.0;P<0.001), the area under ROC curve of CTCs was 0.885 (95%CI: 0.805-0.965), cut-off value was 7.68/ml, sensitivity was 80.4%, specificity was 96.4%. The area under ROC curve of Alu 247/115 was 0.727(95%CI: 0.608-0.847), cut-off value was 0.431, sensitivity was 71.7%, specificity was 71.4%. The AUC of CTCs and Alu 247/115 was 0.919 (95%CI 0.854-0.984), which was higher than the single test of each indicator. Conclusions CTCs and cfDNA may be the potential biological indicators for breast cancer diagnosis. The combined detection of CTCs and cfDNA maybe improve the diagnosis rate of breast cancer patients.

ABSTRACT

Goose hemorrhagic polyomavirus (GHPV) is not a naturally occurring infection in geese in China; however, GHPV infection has been identified in Pekin ducks, a domestic duck species. Herein, we investigated the prevalence of GHPV in five domestic duck species (Liancheng white ducks, Putian black ducks, Shan Sheldrake, Shaoxing duck, and Jinyun Sheldrake) in China. We determined that the Jinyun Sheldrake duck species could be infected by GHPV with no clinical signs, whereas no infection was identified in the other four duck species. We sequenced the complete genome of the Jinyun Sheldrake origin GHPV. Genomic data comparison suggested that GHPVs share a conserved genomic structure, regardless of the host (duck or geese) or region (Asia or Europe). Jinyun Sheldrake origin GHPV genomic characterization and epidemiological studies will increase our understanding of potential heterologous reservoirs of GHPV.

ABSTRACT

Objective To investigate the ATP binding cassette transporter A1 (ABCA1) expression in perihematomal tissue of mouse cerebral hemorrhage model induced by collagenase. Methods Stereotactic injection of type Ⅳ collagenase was used to induce a model of caudate putamen intracerebral hemorrhage in mice. The behavioral scores were use to assess neurological deficits at 24 h, 48 h and 72 h after model making. Neisserian staining was used to detect the morphology of neurons around hematomas.Immunohistochemical staining and Western blot analysis were used to detect the expression of ABCA1 around hematomas. Results Nissl bodies reduction, atrophy, necrosis of perihematomal neurons were observed and aggravated over time. Immunohistochemical staining and Western blot analysis showed that the expression level of ABCA1 in the perihematomal tissue was significantly higher than that in the sham operation group (all P < 0. 05), and the expression level increased significantly with time (all P < 0. 05 ).Conclusion ABCA1 was up-regulated after cerebral hemorrhage, suggesting that it might be involved in the pathological process of cerebral hemorrhage.

ABSTRACT

Objective To investigate the role of monocyte subsets in the pathogenesis of type 2 diabetes mellitus(T2DM), the expression was detected on lipoprotein-associated phospholipase A2(LP-PLA2) mRNA in peripheral blood monocytes subsets of type 2 diabetic patients. Methods After the peripheral blood of 32 type 2 diabetic patients and 22 healthy controls were collected,the percentages of the monocytes subsets were detected by flow cytometry. The expression of LP-PLA2 mRNA in monocytes subsets were detected by PCR. After monocyte subsets of healthy subjects were induced into macrophages and stimulated by the serum of type 2 diabetic patients for 24h,LP-PLA2 mRNA expression was detected. Results Compared with the control group, the percentage of classical monocytes in T2DM group was decreased, while the LP-PLA2 mRNA expression and percentage of nonclassical,intermediate monocytes were significantly increased(all P<0.05). In addition,the homeostasis model assessment for insulin resistance index was positively correlated with LP-PLA2 mRNA expression in non-classical(P<0.05)and intermediate monocytes(P<0.01)of type 2 diabetic patients. Compared with type 2 diabetic patients without carotid atherosclerosis, the levels of LP-PLA2 mRNA in intermediate and nonclassical monocytes were significantly higher than those in type 2 diabetic patients with carotid atherosclerosis(P<0.05). The level of LP-PLA2 mRNA in non-classical monocytes-derived macrophages stimulated with the serum of type 2 diabetic patients was significantly higher than that in the control group(P<0.05). Conclusion Monocytes subsets from type 2 diabetic patients are abnormally skewed toward to intermediate and non-classical monocytes with high expression of LP-PLA2 mRNA,which may play an important role in the pathogenesis of type 2 diabetes mellitus and atherosclerosis.

ABSTRACT

Duck circovirus(DuCV),a potential immunosuppressive virus,was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction(PCR)based method. In this study,a total of 138 sick or dead duck samples from 18 different farms were examined with an average DuCV infection rate of~35%. It was found that ducks between the ages of 40~60 days were more susceptible to DuCV. There was no evidence showing that the DuCV virus was capable of vertical transmission. Farms with positive PCR results exhibited no regularly apparent clinical abnormalities such as feathering disorders,growth retardation or lower-than-average weight. The complete genomes of 9. strains from Fujian Province and 1 from Zhejiang Province were sequenced and analyzed. The 10 DuCV genomes,compared with others genomes downloaded from GenBank,ranged in size from 1988 to 1996 base pairs,with sequence identities ranging from 83.2% to 99.8%. Phylogenetic analysis based on genome sequences demonstrated that DuCVs can be divided into two distinct genetic genotypes,Group I(the Euro-USA lineage)and Group II(the Taiwan lineage),with approximately 10.0% genetic difference between the two types. Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species,including Duck,Muscovy duck,Mule duck,Cheery duck,Mulard duck and Pekin duck.
