Objective To investigate the value of Pituitrin in neonatal cardiopulmonary resuscitation.Methods Seventy-three cases with neonatal cardiopulmonary arrest admitted in emergency department and NICU in our hospital were collected during 2007 to 2011.Newborns who did not respond to conventional neonatal resuscitation therapy were divided into two groups:epinephrine group 47 cases (control group) and Pituitrin combined with epinephrine group 26 cases (treatment group).Results There were no statistical difference (x2 =0.956,P ＞ 0.05) between treatment group and control group in the rates of initial resuscitation success (23.1％,6/26 vs 34.0％,16/47).Conclusion Pituitrin combined with epinephrine has similar efficacy with the use of epinephrine in neonatal cardiopulmonary resuscitation.

Objectives To explore the changes of T helper (Th) lymphocyte and its related factors in children with syste-mic-onset juvenile idiopathic arthritis (SoJIA). Methods A total of 36 SoJIA inpatients, hospitalized from January 2012 to June 2013, were divided into active phase group and remission group. In addition, 20 healthy children were selected as normal con-trols. Th1, Th2 and Th17 cell ratios in peripheral blood mononuclear cells were detected and compared between each group by flow cytometry. Serum interferon-γ(INF-γ), interleukin-4 (IL-4), interleukin-17 (IL-17) levels were measured by enzyme-linked immunosorbent assay. Results The proportions of Th17 cells over CD3+CD8-cell were (3.30±2.15)%, (1.78±1.14)%and (1.22± 1.14)%in active phase group, remission group and control group. The difference among three groups was significant (H=14.437, P=0.001), and the active phase group had higher proportion of Th17 than the other two groups (P<0.05). The ratio of Th1 and Th2 over CD3+CD8-cell between each group was not significantly different (P>0.05). The serum IL-17 levels were (125.82 ± 45.87) pg/ml, (57.79±25.84)pg/ml and(50.02±18.37)pg/ml in active phase group, remission group and control group with signifi-cant difference among three groups (F=31.82, P=0.000), and the active phase group had higher level of IL-17 than the other two groups (P<0.05). But serum INF-γ and IL-4 were not significantly different between each group (P>0.05). Conclusions Acquired cellular immunity is involved in pathogenesis of SoJIA, the increased proportion of Th1 and Th17 cell and the changes of related cytokines seem to correlate with active phage of SoJIA.

Objective To investigate the effects of curcumin on mRNA expression of cytokines related to Toll-like receptor (TLR) 4 signaling in THP-1 cells.Methods After pretreatment with different concentrations (50,25,12.5 mg/L) of curcumin or dexamethasone for 12 hours,THP-1 cells were stimulated by lipopolysaccharide (LPS.1 mg/L) for 4 hours followed by the collection of cells.Then total RNA was isolated from these cells and subjected to reverse transcription-polymerase chain reaction (RT-PCR) for the detection of mRNA expression of tumor necrosis factor receptor-associated factor 6 (TRAF6),interleukin-1 receptorassociated kinase (IRAK1) and nuclear factor (NF)-κB.THP-1 cells without pretreatment or stimulation served as negative control,and those only stimulated with LPS served as LPS group.Results After stimulation with LPS (1 mg/L) for 4 hours,the mRNA expressions of TRAF6,IRAK1 and NF-κB were significantly upregulated in THP-1 cells compared with negative control cells (f=38.69,39.13,23.99,all P<0.01).Curcumin of 50 mg/L and 25 mg/L significantly inhibited the mRNA expressions of TRAF6.IRAK 1 and NF-κB upregulated by LPS with an inhibition rate of more than 50% (all P<0.0 1).Conclusions Certain concentrations of curcumin can inhibit the mRNA expressions of TRAF6.IRAK1 and NF-κB.which demonstrates the regulatory effect of curcumin on the mRNA expressions of TLR4 signaling pathway-associated cytokines.

AIM To study the role of nitric oxide (NO) and nitric oxide synthase (NOS) inhibitors during the early stage of focal cerebral ischemic injury in rats. METHODS The rat models of middle cerebral artery occlusion were established with the intraluminal suture method. The nonselective NOS inhibitor and selective inducible NOS inhibitor were used for investigating the effects of NO and NOS changes in the focal ischemic brain tissue and their respective roles during the early stage of focal cerebral ischemic injury. RESULTS This study showed that nonselective NOS inhibitors(N G nitro L arginine) aggravated brain damage in the early stage of focal cerebral ischemia and selective iNOS inhibitors (Aminoguanidine )did not significantly improve the brain damage , but could decrease markedly the deterioration of brain damage. CONCLUSION It may be concluded that the NO from defferent cells and types of NOS play unlike roles in the early stage of focal cerebral ischemic injury.

Objective To investigate the effects of 13-hexyl-berbefine hydroehlofide (HB-13) and 13-hexyl-paimatine hydrochloride (HP-13) on the activation of nuclear factor-kappa B (NF-kB) and phosphorylation of p38 mitogen-activated protein kinase (MAPK) in a human keratinocyte cell line, HaCaT stimulated by tumor necrosis factor alpha (TNF-α). Methods HaCaT cells were cultured in the presence of various concentrations (0.39, 0.78, 1.56 μg/mL) of HB-13 or HP-13 for 120 minutes followed by the stimulation with recombinant human TNF-α for 120 minutes (in phosphorylatEd-IkB-α test) or 15 minutes (in phosphorylated-p38 test). Then, HaCaT cells were disrupted, total protein was extracted, and the expressions of phosphorylated I B-α and phosphorylated p38 were detected with Western blot. HaCaT cells receiving neither pretreatment nor stimulation served as blank control, untreated HaCaT cells stimulated by rhTNF-α as stimulator control, and HaCaT cells pretreated with turmeric root tuber and stimulated by rhTNF-α as positive control. Results From 0.39 to 1.56 μg/mL, both HB-13 and HP-13 significantly inhibited the expression of p-IkB-α in HaCaT cells stimulated by rhTNF-α, and a nonsignificant dose-dependent trend was observed for their inhibitory effect, with the ICo value being 0.441 μg/mL for I-IB-13 (r = -0.990, n = 3, P > 0.05) and 0.832 μg/mL for HP-13 (r = -0.992, n = 3, P > 0.05). In contrast, neither 1-113-13 nor HP-13 within the experiment concentration range had a significant effect on the expression of p-p38 in HaCaT cells stimulated by rhTNF-α (P > 0.05). Conclusions Within the experimental concentration range, both HB-13 and HP-13 can inhibit the activation of NF-kB in HaCaT cells induced by TNF-α signal, but neither of them suppress the phosphorylation of p38MAPK induced by TNF-α signal in HaCaT cells.

Objective To investigate the effects of triptolide on the expression of a series of proteins associated with interferon-γ (IFN-γ)signaling in HaCaT keratinocytes.Methods After pretreatment with difrerent dosages of triptolide(10-10-10-7 mol/L),HaCaT cells were stimulated by recombinant human IFN-γ(rhIFN-γ,500 U/mL)for various periods followed by the collection of cells.Then,total protein was extracted from these cells and subjected to Western blotting for the detection of expression of interferon-γ receptor α(IFN-γRα),phosphorylated Janus kinase 2(pJAK2)and suppressor of cytokine signaling (SOCS1).Results Triptolide at the concentrations of 10-8 mol/L and 10-7 mol/L significantly inhibited the IFN-γRα expression upregulated by rhIFN-γ(both P＜0.05).The expression of pJAK2 induced bv rhIFN-γ was also suppressed by triptolide at the concentrations of 10-9 moI/L and 10-8 mol/L(both P＜0.05).The inhibition of triptolide on IFN-γRα and pJAK2 expression was dose-dependent and the 50%inhibitory concentrations(IC50 value)were 1.37×10-8 mol/L and 2.83×10-9 mol/L,respectively.On the contrary,triptolide upregulated the expression of SOCS1 stimulated by rhIFN-γ at the concentrations of 10-10,10-9 and 10-8 mol/L(P＜0.05,0.05,0.01,respectively)with the 50%effective dosage(ED50 value)at 3.32 × 10-11 mol/L.Conclusions By inhibiting the expression of IFN-γRα as well as phosphorylation of JAK2 and upregulating the expression of SOCS1,triptolide inhibits the phosphorylation of STAT-1,resulting in the inhibition of genetic transcription of multiple inflammatory factors induced by IFN-γ signaling in HaCaT keratinocytes,and the inhibition probably contributes to the efficacy of triptolide in the treatment of IFN-γ-dependent inflammatory skin disorders,such as psoriasis.
