Objective To explore the role of Th17-and Treg-derived catecholamines during collagen-induced ar?thritis (CIA) progression. Methods Eighteen male DBA/1 mice were randomly divided into control group, CIA model groupⅠ(day 35) and CIA model groupⅡ(day 55). The CIA models were induced by typeⅡcollagen (CⅡ) injection from tails. mRNA expression of Th17 specific transcription factor include ROR-γt, cytokines, IL-17 IL-22, Treg specific transcription factor, Foxp3, cytokines, TGF-βand tyrosine hydroxylase (TH) in lymph nodes were examined by real-time PCR. Co-local?ization of ROR-γt or Foxp3, with TH, vesicular monoamine transporter-2 (VMAT-2) or monoamine oxidase (MAO) in lymph nodes were observed by immunofluorescence staining. Results In lymph nodes of mice in CIAⅠgroup and CIAⅡgroup, mRNA expression of ROR-γt, IL-17, TH and IL-22 were upregulated, while mRNA expression of Foxp3 and TGF-βex?pression was downregulated compared to those expression in control group. The upregulated expression of IL-17 was signifi?cantly reduced in CIAⅡgroup compared with that in CIAⅠgroup. In the lymph nodes of both intact and CIA mice, co-lo?calization of ROR-γt or Foxp3 with TH, VMAT-2 or MAO was seen in some cells. The numbers of cells that are double-pos?itive of ROR-γt/TH,ROR-γt/VMAT-2 and ROR-γt/MAO IL-17 were increased in CIA groups compared to those in con?trol group. And they are significantly reduced in CIAⅡgroup compared with those in CIAⅠgroup. Conclusion The abili?ty to synthesize catecholamines in Th17 cells was increased in lymph node in mice from CIA groups compared to that in con?trol group. The increased catecholamines production from Th17 cells in lymph nodes may be involved in the anti-inflammato?ry progression in CIA.

Objective To explore the clinical application value of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) in diagnosis and treatment of symptomatic patent ductus arteriosus (sPDA) in preterm infants. Methods A total of 107 preterm infants with gestational age of 28-32 weeks and birth weight less than 1500 g who were admitted to the neonatal intensive care unit from October 2013 to September 2014 were recruited. Plasma NT-proBNP were on 4th and 7th day after birth. The echocardiography examination was performed within 30 minutes after the blood was drawn. According to the echocardiography examination on 4th day after birth, the infants were divided into the patent ductus arteriosus (PDA) group (n?=?39) and the control group (n?=?68). According to whether there were signiifcant hemodynamics changes of ultrasonography and clinical symptoms, the PDA group were classiifed into the sPDA group (n?=?20) and the asymptomatic PDA group (asPDA, n?=?19). Then according to whether ibuprofen was taken, the sPDA group was further divided into treatment group (n?=?13) and non-treatment group (n?=?7). Results On the 4th day after birth, the level of plasma NT-proBNP in the sPDA group was signiifcantly higher than that in asPDA group, and the level of plasma NT-proBNP in asPDA group was signiifcantly higher than that in the control group (P?0.05). On the 7th day after birth, the level of plasma NT-proBNP in the sPDA group was signiifcantly higher than that in the asPDA group and the control group (P?0.05), and, however, there was no signiifcant difference between the asPDA group and the control group (P?>?0.05). In the treatment group, the level of plasma NT-proBNP on the 7th day after birth was signiifcantly lower than that on the 4th day after birth (P?0.05). In the non-treatment group, there was no signiifcant difference of the plasma NT-proBNP between the 4th day and the 7th day after birth (P?>?0.05). In PDA group, the level of plasma NT-proBNP on the 4th day after birth was positively correlated with ductus arteriosus (DA) diameter, ratio of the left atrium to aortic root diameter (LA/AO ratio) and transductal diameter-to-left pulmonary artery ratio (TDD/LPA) (r?=?0.498-0.670, respectively). The area under receiver operator characteristic (ROC) curve for prediction of sPDA by the plasma NT proBNP on the 4th day after birth was 0.969 (95%CI:0.938-1.000). When the NT-proBNP was 13964 pg/ml on the 4th day after birth, the sensitivity for diagnosis sPDA was 95%, the speciifcity was 95.4%. Conclusions The level of plasma NT-proBNP is signiifcantly higher in preterm infants with sPDA and is decreased after treatment. Plasma NT-proBNP on the 4th day after birth is a sensitive marker for predicting sPDA. Dynamic monitoring of plasma NT-proBNP has important clinical value in selection of the treatment strategy in preterm infants with PDA.
