Objective To investigate the changes of N-terminal pro-brain natriuretic peptide (NT-proBNP) in neonates with hypoxic-ischemic encephalopathy (HIE) complicated by myocardial ischemic injury. Methods Forty neonates with HIE ( 16 cases with concurrent myocardial injury and 24 cases without) were enrolled. Twenty healthy neonates were used as control. Plasma NT-proBNP levels were measured using enzyme immunoassay. Cardiac function was measured by echocardiography. Results ( 1 ) The mean plasma NT-proBNP levels in patients with myocardial injury[(350 ± 56) pmol/L]were significantly higher than those in patients without myocardial injury[(135 ± 37 ) pmol/L]and in the control group [(117 ±23) pmol/L](P ＜0. 05). (2) The NT-proBNP levels in mild,moderate and severe HIE neonates were ( 132 ±34) pmol/L, (247 ±43) pmol/L and (343 ±53) pmol/L. Compared with the control group,the NT-proBNP levels in the neonates with moderate and severe HIE significantly increased. There were significant differences in the NT-proBNP levels among the mild, moderate and severe HIE neonates ( P ＜ 0. 05 ).(3) In patients with myocardial injury,the NT-proBNP levels significantly decreased in the convalescent phase [(250±78) pmol/L]compared with those in the acute phase[(350±56) pmol/L](P ＜0.05). (4) The NT-proBNP levels were significantly related with left ventricular ejection fraction. Conclusion Plasma NT-proBNP levels increase in neonates with HIE complicated with myocardial ischemic injury in the acute phase.Detection of NT-proBNP levels maybe useful in the diagnosis of myocardial ischemic injury and severe HIE.

Taxol is one of the most potent anti-cancer agents, which is extracted from the plants of Taxus species. Isopentenyl diphosphate isomerase (IPI) catalyzes the reversible transformation between IPP and DMAPP, both of which are the general 5-carbon precursors for taxol biosynthesis. In the present study, a new gene encoding IPI was cloned from Taxus media (namely TmIPI with the GenBank Accession Number KP970677) for the first time. The full-length cDNA of TmIPI was 1 232 bps encoding a polypeptide with 233 amino acids, in which the conserved domain Nudix was found. Bioinformatic analysis indicated that the sequence of TmIPI was highly similar to those of other plant IPI proteins, and the phylogenetic analysis showed that there were two clades of plant IPI proteins, including IPIs of angiosperm plants and IPIs of gymnosperm plants. TmIPI belonged to the clade of gymnosperm plant IPIs, and this was consistent with the fact that Taxus media is a plant species of gymnosperm. Southern blotting analysis demonstrated that there was a gene family of IPI in Taxus media. Finally, functional verification was applied to identify the function of TmIPI. The results showed that biosynthesis of β-carotenoid was enhanced by overexpressing TmIPI in the engineered E. coli strain, and this suggested that TmIPI might be a key gene involved in isoprenoid/terpenoid biosynthesis.

Objective To explore the differences in the expression of inhibin(INH)receptors and activin (ACT)receptors in the follicular/luteinic phase in normal human ovaries and their relationship with female endocrine hormone levels.Methods Real time PCR and immunohistochemistry were used to determine the expression of inhibin receptors(INHR)genes,activin receptors(ACTR)genes.Serum estradiol(E2),follicle stimulating hormone(FSH),luteinizing hormone(LH),INHB,ACTA levels were determined by a solid quantitative sandwich enzyme immunoassay technique(Sandwich ELISA)in 21 women during follicular phase and another 21 women during luteinic phase,the correlations between each gene and each hormone were analyzed.Results(1)ACT type Ⅰ and Ⅱ receptors genes(ACTR Ⅰ A,ACTR Ⅰ B,ACTRⅡA,ACTR Ⅱ B)and INH receptor β-glycan genes were expressed higher in the follicular phase than in the luteinic phase:ACTR Ⅰ A(0.50±0.17 vs 0.36±0.18;P＜0.05),ACTR Ⅰ B(0.050±0.019 vs0.036±0.020;P＜0.05),ACTRⅡ A(0.10±0.04 vs 0.07±0.04;P＜0.05),ACTR Ⅱ B(0.28±0.10vs 0.19±0.11;P＜0.05),β-glycan(0.26±0.10 vs 0.17±0.09;P＜0.01).(2)The intensities of ACTR I A,ACTR Ⅱ A,β-glycan immunostaining in human normal ovaries in the follicular phase were significantly stronger compared to those in luteinic phase.In the follicular phase β-glycan expression was positively correlated with serum E2,FSH,LH,INHB levels.The correlation coefficient was 0.53(P＜0.05).0.74(P＜0.01),0.85(P＜0.01)and 0.76(P＜0.01)respectively.Conclusion In normal human ovary in the follicular phase INH and ACT bind their receptors and down-regulate or up-regulate FSH,thus influencing the follicular development.

The human immunodeficiency virus type 1(HIV-1)can interact with and exploit the host cellular machinery to replicate and propagate itself.Numerous studies have shown that the Mitogen-activated protein kinase(MAPK)signal pathway can positively regulate the replication of HIV-1,but exactly how each MAPK pathway affects HIV-1 infection and replication is not understood.In this study,we used the Extracellular signal-regulated kinase(ERK)pathway inhibitor,PD98059,the Jun N-terminal kinase(JNK)pathway inhibitor,SP600125,and the p38 pathway inhibitor,SB203580,to investigate the roles of these pathways in HIV-1replication.We found that application of PD98059 results in a strong VSV-G pseudotyped HIV-1NL4-3 luciferase reporter virus and HIV-1NL4-3 virus inhibition activity.In addition,SB203580 and SP600125 also elicited marked VSV-G pseudotyped HIV-1NL4-3 luciferase reporter virus inhibition activity but no HIV-1NL4-3 virus inhibition activity.We also found that SB203580 and SP600125 can enhance the HIV-1 inhibition activity of PD98059when cells were treated with all three MAPK pathway inhibitors in combination.Finally,we show that HIV-1virus inhibition activity of the MAPK pathway inhibitors was the result of the negative regulation of HIV-1 LTR promoter activity.

Objective To investigate the effects of spinal nerve ligation (SNL) on the changes of intestinal pathology and the levels of serum immunoglobulin in rats with ulcerative colitis.Methods Thirty-six healthy male rats, weighing 200-220 g, were randomly divided into three groups using the random number table method: spinal nerve ligation model group (group SNL), sham-operationgroup (group Sham) and non-operatedcontrol group (group Con), 12 in each group.After the establishment of SNL models, the three groups were given trinitro-benzene-sulfonic acid (TNBS) to induce ulcerative colitis.The serum level of immunoglobulin (IgG, IgM) were measured on the day before SNL, before TNBS modeling and 7, 14 d after TNBS modeling, respectively.Besides, the intestinal pathology were observed on 7 d after TNBS modeling.Results The basic values of IgM and IgG before operation were not statistically different among three groups.The level of IgG in group SNL was lower than that in group Sham after SNL operation with no significant difference, but the level of IgM was significantly lower than that of group Sham (P<0.05).On 7 d after TNBS modeling, both levels of IgG and IgM in group SNL were significantly lower than those in group Sham and group Con (P<0.01).On 14 d after TNBS modeling, the level of IgG in group SNL was significantly lower than that in group Sham and group Con (P<0.05).Furthermore, the colon lesions were more extensive and the inflammation was more serious in group SNL than those in group Sham and group Con on 7 d after TNBS modeling.Conclusion Neuropathic pain suppress immune activities, reduces the serum level of IgM and IgG and aggravates intestinal inflammation caused by TNBS.

Abstract: Objective　To investigate the frequency of peripheral blood T cells among patients positive for both hepatitis B virus surface antigen (HBsAg) and surface antibody (HBsAb). Methods　 Thirty six patients with co-existence of HBsAg and HBsAb diagnosed were enrolled as the experimental group, who were admitted by Shanghai tenth people's hospital and Wuxi 9th people's hospital from 2014 to 2020. while 40 patients tested positive for HBsAg and negative for HBsAb served as controls, who were admitted by Wuxi 9th people's hospital. Flow cytometry was used to detect and compare the proportions of peripheral blood CD3+, CD4+ and CD8+ T cells between the experimental and control groups. In addition, the associations of serum HBsAb level with peripheral blood T cell proportions, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were examined among chronic hepatitis B patients with co-existence of HBsAg and HBsAb using Pearson correlation analysis. Results　The median age, gender distribution, mean ALT and AST concentrations, proportion of HBV DNA viral load>103 copies/mL, seroprevalence of HBV E antigen (HBeAg), seroprevalence of HBV E antibody (HBeAb), seroprevalence of HBV core antibody (HBcAb) were comparable between the experimental and control groups, and there were no significant difference in them (P>0.05). There were no significant difference between the experimental and control groups in terms of CD3+ T cell proportion [(71.83±1.50)% vs (72.75±1.47)%; t=0.66, P>0.05], CD4+ T cell proportion [(36.81±1.53)% vs (39.88±1.57)%; t=1.43, P>0.05] and CD8+ T cell proportion [(33.17±2.04)% vs (32.40±1.75)%; t=0.77, P>0.05]. Pearson correlation analysis revealed that the serum HBsAb level did not significantly correlate with peripheral blood CD3+ (r=0.026, P=0.65), CD4+ (r=‒0.08, P=0.16) and CD8+ T cell proportions (r=0.09, P=0.24), CD4+/CD8+ T proportion (r=‒0.005, P=0.35), serum ALT (r=0.04, P=0.56) and AST levels (r=0.002, P=0.69) among chronic hepatitis B patients with co-existence of HBsAg and HBsAb. Conclusions　There are no significant differences between HBsAg+/HBsAb+ and HBsAg+/HBsAb- CHB patients in terms of peripheral blood CD3+, CD4+ and CD8+ T cell proportions.

Objective To explore the characteristics of ischemia-reperfusion induced infant lung damage and the potential mechanisms of the injuried.Methods Both infant (15-21 days old) and adult (5-6 months old) rabbits were subjected to either ischemia-reperfusion or sham operation.Ischemia-reperfusion was induced by clamping the right pulmonary hilum for 1 hour and then removal of the clamp for 4 hours under anesthesia.The lung tissue were sampled for histological examination by light and electron microcopies and for biological evaluation of mitochondrial alterations.Production and expression of free radical species-hydroxyl radical (ROS-HR),malondialdehyde (MDA),superoxide dismutase (SOD),glutathione peroxidase (GSH-PX),myeloid differentiation factor-88 (MyD-88),and nuclear factor-κB (NF-κB) in the lung tissue were also examined.In addition,circulating levels of interleukin-β and tumor necrosis factor-α were measured during the ischemia-reperfusion process.Results In comparison to adult lungs,the infant lungs had more increased neutrophil infiltration,edema,swelled alveolar epithelial and endothelial cells,and severer mitochondrial impairment reflected by damage of the inner membrane as well as decrease in the membrane potential after ischemia-reperfusion.The lungs in infant animals subjected to sham operation displayed higher levels of ROS-HR and MDA and lower levels of SOD and GSH-PX than those in adult controls.The lungs in infants with ischemia-reperfusion were found to further produce more ROS-HR,and MDA,and less SOD and GSH-PX than the ischemia-reperfused adult lungs.Moreover,the circulating levels of interleukin-1β and tumor necrosis factor-α were elevated during the period of ischemia-reperfusion,particularly in the infant animals,which appeared to be associated with the expression of MyD-88 and NF-κB in the lungs.Conclusion Lung ischemia-reperfusion causes more severe lung damage in infants than in adults,probably due to combination of low antioxidant capacity and overproduction of ROS in infants.
