Moreover, 30 healthy individuals who came for physical examinations in the same period were served as the control group. ELISA was used to detect the plasma ET-1 and IL-8 levels, and their correlation was analyzed. The arterial blood gas and coagulation fibrinolysis indicators among the three groups were compared.Results: The plasma ET-1 and IL-8 levels in observation 1 and 2 groups were significantly higher than those in the control group. The plasma ET-1 and IL-8 levels in observation 1 group were significantly higher than those in observation 2 group. PaO2 in observation 1 and 2 groups was significantly lower than that in the control group, while PaCO2 was significantly higher than that in the control group. The comparison of PaO2 and PaCO2 between the two groups was not statistically significant. PT and APTT in observation 1 and 2 groups were significantly shortened when compared with the control group, while TT was significantly delayed. PT in observation 1 group was significantly shortened when compared with observation 2 group. Fbg and t-PA contents in observation 1 and 2 groups were significantly higher than those in the control group. Fbg, t-PA, and D-D contents in observation 1 group were significantly higher than those in observation 2 group.Conclusions:The hypercoagulation state is presenting in patients with AECOPD merged with CHD, with increased ET-1 and IL-8, both of which can play a synergistic effect, and are involved in the pathogenesis.展开更多

Blood and liver tissue were sampled at the time of sacrifice on the 8th day post operation. Plasma total bilirubin, endotoxin, levels,as well as TNF-α, ET-1 and NO contents in liver tissue were determined.RESULTS: Plasma endotoxin and total bilirubin levels were significantly higher in both bile duct-ligated and bile ductligated plus glycine-treated rats than in sham-operated animals (P=0.000613, 0.00921 and 0.00737, 0.00841respectively), whereas they did not display any statistically significant difference between the former groups (P=0.417and 0.374 respectively). Likewise, TNF-α, ET-1 and NO contents in both plasma and liver tissue were significantly increased in both bile duct-ligated and bile duct-ligated plus glycine-treated rats compared with sham-operated animals (P=-0.00813, 0.00793, 0.00671, 0.00804, 0.00872, and 0.00947 in plasma and 0.00531, 0.00785, 0.00912, 0.00981and 0.00635 in liver tissue respectively). However, these inflammatory mediators in both plasma and liver tissue were significantly reduced in bile duct-ligated rats fed on 5 %glycine solution compared with that without (P=0.00953,0.00891, 0.0795, 0.00867, 0.0697 and 0.00907 in plasma and liver tissue respectively).CONCLUSION: Reduction of TNF-α, ET-1 and NO contents in plasma and liver tissue of rats fed on glycine may be helpful to alleviate pathological lesions in obstructive jaundice.展开更多

The heterogeneity of the tumor microenvironment is high.However, the role of plasma cells controlling the tumor migration progression in TNBC is still not fully understood.Methods: We analyzed single-cell RNA sequencing data from five HER2 positive, 12ER positive/PR positive, and nine TNBC samples. The potential targets were validated by immunohistochemistry.Results: Plasma cells were enriched in TNBC samples, which was consistent with validation using data from The Cancer Genome Atlas. Cell communication analysis revealed that plasma cells interact with T cells through the intercellular adhesion molecule 2–integrin–aLb2 complex, and then release interleukin 1 beta(IL1B), as verified by immunohistochemistry, ultimately promoting tumor growth.Conclusion: Our results revealed the role of plasma cells in TNBC and identified IL1B as a new prognostic marker for TNBC.展开更多
