Objective:To evaluate the potential of IgG N-glycans as diagnostic biomarker for ankylosing spondylitis (AS) by comparing and analyzing the IgG N-glycan profiles with AS and healthy controls.Methods:A 1∶1 matched case-control study design was adopted, 81 AS patients who visited the Department of Rheumatology and Immunology at Taian City Central Hospital and the Second Affiliated Hospital of Shandong First Medical University between July 2020 and June 2021 were recruited. These patients were matched with 81 healthy individuals undergoing routine physical checkup. The levels of IgG N-glycosylation in human plasma were quantitatively measured using ultrahigh-performance liquid chromatography. Binomial logistic regression analysis was performed to identify IgG N-glycan biomarkers associated with AS.Results:A total of 14 primary glycans and 13 derived traits showed statistically significant differences between the AS case group and the control group. Binomial logistic regression analysis showed that glycan peak 4, agalactosylated glycans, fucosylated glycans, and fucosylated agalactosylated glycans were positively associated with AS[ OR(95% CI)=1.12(1.01, 1.42), 1.21(1.03, 1.43), 1.48(1.08, 2.03), and 1.27(1.04, 1.55); P=0.036, 0.022, 0.039, 0.020, respectively]. In terms of diagnostic performance, the single glycan GP4 exhibited the largest area under the ROC curve, with an AUC (95% CI) 0.751 (0.677, 0.826), while the combined glycan indicators (GP4+G0+F+FG0) achieved an AUC (95% CI) 0.768(0.697, 0.840). Conclusion:IgG N-glycans have the potentials to serve as candidate biomarkers for AS, and warrants further investigation.

Objective: To understand the level of compassion satisfaction of medical oncology nurses and to explore the mediating effect of resilience in the relationship between empathy ability and compassion satisfaction of medical oncology nurses, and to investigate the moderating effect of social support in this mediating role. Methods: A total of 291 medical oncology nurses from 7 general hospitals in Dalian were measured with self-made general questionnaire, professional quality of life scale, Chinese version of Jefferson empathy scale, perceived social support scale and Ego-Resiliency Scale. Results: The scores of compassion satisfaction of medical oncology nurses was (34.79±5.87).Pearson correlation analysis showed that there was a significant positive correlation between empathy, resilience, social support and compassion satisfaction (r=0.222-0.402, P<0.01). Resilience partially mediated the relationship between empathy ability and compassion satisfaction, the value of mediating effect was 23.1% of the total effect. The effect of resilience and compassion satisfaction among medical oncology nurses was also moderated by social support, that is, social support regulates the latter half of the process of empathy, resilience and compassion satisfaction. The higher the level of social support, the stronger the mediating effect of empathy through resilience on compassion satisfaction. Conclusions The level of compassion satisfaction of medical oncology nurses in Dalian is low and needs to be improved. The are close relationships among empathy ability, resilience, social support and compassion satisfaction. It is a moderated mediating effect model. It is suggested that managers should pay attention to the role of psychological resilience and provide high-level social support to improve the level of compassion satisfaction of medical oncology nurses.

Objective: To evaluate the effect of human CCR1 (hCCR1) gene overexpression on the migration of human bone marrow-derived mesenchymal stem cells (hMSCs) towards hepatocellular carcinoma (HCC), and to examine the application prospects of MSCs as gene delivery vectors in the treatment of HCC. Methods: The hCCR1 gene was subcloned into a lentiviral vector to generate the recombinant plasmid pLV-hCCR1. The pLV-hCCR1 plasmid and two other packaging plasmids were co-transfected into 293T cells using calcium phosphate, and the virus-containing supernatant was collected. hMSCs were then infected with the recombinant lentivirus, and the expression of hCCR1 mRNA and protein was analyzed by RT-PCR and Western blot, respectively. The effect of CCR1 gene overexpression on the in vitro migration of hMSCs was examined using the Transwell migration assay. Orthotopic nude mice models of HCC were established using the MHCC-97H-GFP cell line, and the mice were divided into two groups (n = 8 per group). hMSCs were then intravenously injected via the tail vein into the tumor-bearing nude mice to examine the effect of hCCR1 overexpression on the in vivo migration of hMSCs towards HCC. Unpaired Student’s t-test was used for two-group comparisons, and one-way ANOVA was used for multi-group comparisons. Results: Restriction enzyme digestion and DNA sequencing demonstrated that the recombinant plasmid pLV-hCCR1 was constructed successfully. The LV-hCCR1 lentivirus packaged by 293T cells has high infection efficiency in hMSCs, and hCCR1 was overexpressed in hMSCs after LV-hCCR1 infection. Transwell migration assay showed that hCCR1-transfected hMSCs had significantly enhanced migration towards HCC cell line-derived condition medium (CM) compared with the control RFP-hMSCs [(134.8±15.7)/LPF vs (83.5±10.9)/LPF, t = 10.40, P < 0.01]. In vivo migration experiment also demonstrated that there was significantly higher number of hCCR1-hMSCs localized within the MHCC-97H-GFP xenografts than hMSCs-RFP on day 14 following intravenous injection of hMSCs in mice [(86.7±14.1)/HPF vs (54.5±9.6)/HPF, t = -7.32, P < 0.01]. Conclusion Overexpression of CCR1 gene can significantly enhance the migration capacity of hMSCs towards HCC cells in vitro and in vivo. This study provides evidence for potential clinical application of MSCs as more effective delivery vehicles in cancer gene therapy.

In order to determine the effect of various hosts on feeding performance of Rhipicephalus (Boophilus) microplus, we used 3 mammalian species as hosts, cattle (Qinchuan), sheep (T an), and rabbits (Japanese white rabbit) for infest-ing ticks. Five hundreds of R. microplus larvae were exposed to each animal (3 animals/host species). Tick recoveries were 11.0%, 0.47%, and 5.5% from cattle, sheep, and rabbits, respectively. The averages of tick feeding periods were not significantly different on cattle, sheep, and rabbits, 28.8, 25.3, and 26.7 days, respectively. The average weights of individual engorged female from cattle, sheep, and rabbits were 312.5, 219.1, and 130.2 mg, respectively and those of egg mass weights each to 85.0, 96.6, and 17.8 mg. The highest egg hatching rate was in the ticks from cattle (96.0%), fol-lowed by those from rabbits (83.0%) and sheep (19.2%). These data suggest that rabbits could be as an alternative host to cultivate R. microplus for evaluating vaccines and chemical and biological medicines against the tick in the laboratory, although the biological parameters of ticks were less than those from cattle.

Theileria annulata is a tick-borne intracellular protozoan parasite that causes tropical theileriosis, a fatal bovine lymphoproliferative disease. The parasite predominantly invades bovine B lymphocytes and macrophages and induces host cell transformation by a mechanism that is not fully comprehended. Analysis of signaling pathways by quantitative real-time PCR (qPCR) could be a highly efficient means to understand this transformation mechanism. However, accurate analysis of qPCR data relies on selection of appropriate reference genes for normalization, yet few papers on T. annulata contain evidence of reference gene validation. We therefore used the geNorm and NormFinder programs to evaluate the stability of 5 candidate reference genes; 18S rRNA, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ACTB (β-actin), PRKG1 (protein kinase cGMP-dependent, type I) and TATA box binding protein (TBP). The results showed that 18S rRNA was the reference gene most stably expressed in bovine PBMCs transformed and non-transformed with T. annulata, followed by GAPDH and TBP. While 18S rRNA and GAPDH were the best combination, these 2 genes were chosen as references to study signaling pathways involved in the transformation mechanism of T. annulata.

Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.
