The cGAS-STING pathway plays a significant role in host defense against viral and bacterial infection.In the process,the cytoplasmic free DNA,considered as a danger signal,is recognized by nucleotidyl transferase cGAS.cGAS is activated by double-stranded DNA (dsDNA) and catalyzes the synthesis of a noncanonical cyclic dinucleotide 2'5'-cGAMP from adenosine triphosphate (ATP) and guanosine triphosphate (GTP).cGAMP serve as an endogenous second messenger to stimulate the induction of type Ⅰ interferons via STING.In addition to the exogenous bacterial or viral DNA,abnormal deposition of host DNA in cytosol also activates the cGAS-STING signaling pathway cascade,resulting in inflammation and autoimmune diseases.Subsequent studies found that this pathway also plays an important role in tumor's responsiveness to radio-therapy and chemo-therapy.Activation of cGAS-STING pathway produces or enhances the therapeutic efficacy.These findings suggest that specifically interfering with cGAS-STING activation may hold therapeutic value for the treatment of cancer,infection and inflammatory diseases.In this paper,the activation mechanism of cGAS-STING pathway and its relationship with the treatment of diseases were summarized,and the regulation of cGAS-STING pathway was introduced in detail.

Objective To investigate the relationship between the preterm infants after premature rupture of the membranes(PROM)brain injury and some cellular factors in the umbilical cord blood and amniotic fluid,and ana-lyze the biological markers with great predictive value,and provide a theoretical basis for early monitoring of brain injury in premature infants. Methods One hundred and thirty - nine singleton infants with PROM,their gestation less than 34 weeks,were evaluated. The umbilical cord blood and amniotic fluid of cytokines,including interleukin - 1β(IL - 1β),IL - 4,IL - 6,IL - 8,IL - 10,IL - 17A,tumor necrosis factor alpha(TNF - α),granulocyte colony - stimu-lating factor(G - CSF),monocyte chemotactic protein - 1(MCP - 1),S100B protein and soluble intercellular adhe-sion molecule - 1(sICAM - 1)levels were measured with Luminex liquid chip. All the premature infants underwent brain imaging for the diagnosis of brain damage. All cases were divided into brain injury group and non - brain injury group based on brain imaging examination. Results The concentration of IL - 10 in cord blood was significantly lower in the brain injury group than that in the non - brain injury group,and the difference was statistically significant(P ﹤0. 05). The levels of IL - 1β,IL - 6,IL - 8,TNF - α,G - CSF,MCP - 1,S100B and sICAM - 1 in the brain injury group were significantly higher than those of non - brain injury group,and the differences were statistically significant (all P ﹤ 0. 05). The levels of IL - 1β,IL - 6,IL - 8,TNF - α,G - CSF,MCP - 1 and sICAM - 1 in the amniotic fluid were significantly higher than those of non - brain injury group,and the differences were statistically significant(all P ﹤ 0. 05),but amniotic fluid S100B protein level was similar between 2 groups,which had no statistical significance (P ﹥ 0. 05). To predict the value of brain damage in premature infants,the highest sensitivity in cord blood was S100B protein,the highest specificity was IL - 6. The highest sensitivity in amniotic fluid was IL - 1β,and the highest specificity was IL - 8. The levels of IL - 4 and IL - 17A in the umbilical cord blood and amniotic fluid,IL - 10 in amniotic fluid were very low,and had no predictive value for brain damage. Conclusions Many biological markers in umbilical cord blood and amniotic fluid provide information about the risk of brain injury in premature infants. The highest sensitivity in cord blood was S100B protein,the highest specificity was IL - 6. The highest sensitivity in amniotic fluid was IL - 1β,the highest specificity was IL - 8. Changes in inflammation - related biomarkers suggest that brain damage in the preterm infants might be associated with intrauterine inflammation.

Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.
