1.Research progress of neutrophil extracellular traps and related targeted drugs for the treatment of inflammatory diseases
Acta Pharmaceutica Sinica 2021;56(3):669-678
The inflammatory response is an essential role of innate immune cells such as neutrophils, which plays an important role in the occurrence and development of inflammatory diseases. Neutrophil extracellular traps (NETs) are responsible for killing microorganisms and inducing the inflammatory response. We review the function of NETs in inflammatory diseases based on research publications since 2016. In addition, the ability of drugs that target NETs to ameliorate inflammation-related diseases is summarized. This review suggests a new strategy of targeting NETs for the treatment of inflammation-related diseases.

This study is to investigate the protein and mRNA expressions of pro-inflammatory and anti-inflammatory cytokines in U937 foam cells and effects of Ginkgo biloba extract (GbE) on the cytokines.U937 cells were cultured with different concentrations of GbE (0.1,1,and 10 μg·L-1),and stimulated by 100 mg·L-1 oxidized low density lipoprotein (ox-LDL) for 24 h.The expressions of interleukin-1β (IL-1β),tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) in culture solution were detected by enzyme-linked immunosorbant assay (ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR).The results showed that incubated with 100 mg·L-1 ox-LDL for 24 h,the U937 cells became foam cells,the protein or mRNA expressions of IL-1β,TNF-α,IL-10,and its receptor IL-10R in U937 foam cells were higher markedly than those in normal U937 cells.When the cells were pretreated with GbE (0.1,1,and 10 μg·L-1),the increases of IL-1β and TNF-α in U937 foam cells were remarkably inhibited,but IL-10 expression increased greatly.Especially when cells were pretreated with 10 μg·L-1 GbE,the protein and mRNA expressions of IL-1β and TNF-α were markedly lower than those in U937 foam cells.The protein expression of IL-10 and mRNA expressions of IL-10 and its receptor IL-10R were markedly higher than those in U937 foam cells.GbE inhibited production of pro-inflammatory cytokines IL-1β and TNF-α,but up-regulated the production of anti-inflammatory cytokine IL-10 and its receptor IL-10R in U937 foam cells,which might be related with its anti-atherosclerotic actions.

Aim To investigate the neuroprotective effects of osthole(Ost)on the primary cultured cortical neurons transfected with APP595/596 gene and its underlying mechanism.Methods Neonatal mouse cortical neurons were transfected with APP595/596 gene to establish AD cell models for the further study.Then,the cell viability was detected by CCK-8 assay,and the leakage of lactate dehydrogenase(LDH)was assayed by LDH kit to evaluate the injury degree.Transferase-mediated nick end labeling(TUNEL)was used to evaluate the cell apoptosis.The expression of β-amyloid peptide(Aβ)and β-site APP cleaving enzyme 1(BACE1)was measured by immunofluorescence,while the miRNA-107 was measured by RT-PCR.Results Compared to model group,Ost could significantly improve the neurons viability,decrease the LDH release and prevent the apoptosis.Ost also inhibited the expression of Aβ and BACE1 at protein level,while enhanced the expression of miRNA-107 at gene level.Conclusion Ost plays a neuroprotective role in neurons transfected with APP595/596 gene in part through up-regulating miRNA-107.

Purpose To investigate the expression of IGF-Ⅱand IGFBP-6 in co1orecta1 cancer,and to exp1ore the c1inica1 significance in co1orecta1 cancer. Methods IGF-Ⅱand IGFBP-6 were detected by immunohistochemistry and RT-PCR in 50 cases of co1orecta1 cancer(experimenta1 group)and 50 cases of the adjacent mucosa(contro1 group). Results (1)In the experimenta1 group,the ex-pression 1eve1 of IGF-Ⅱprotein and mRNA was significant1y higher than the contro1 group. The expression 1eve1s of IGF-Ⅱprotein and mRNA in co1orecta1 cancer were significant1y 1ower than the contro1 group.(2)The expression 1eve1s of IGF-Ⅱand IGFBP-6 were sig-nificant1y different between different tumor infi1tration depth,1ymph node metastasis,invasion depth and Duke’s stages( P<0. 05), but no difference between genders,age and the degree of tumor differentiation( P>0. 05). Conclusions There is a obvious corre1a-tion between of IGF-Ⅱ and IGFBP-6 in c1inica1 patho1ogica1 parameters in co1orecta1 cancer. Combined detection of the two markers may be the bio1ogica1 indicators of occurrence and prognosis of co1orecta1 cancer,and provide a new scheme for diagnosis and treatment of co1orecta1 cancer.
