0.05).Conclusions New criteria of plasma lipid values in 2 to 6 years old children in Beijing are established by our investigation.Criterion of borderline and high of TC and LDL-C levels are settled.Cut-off of hypertriglyceridemia and hypo-high density lipoprotein cholesterolemia are also established.

Aim To study the effects of sodium ferulate on A?induced cognitive deficits and expressions of IL-1? and phospho-p38MAPK proteins.Methods Alzheimers disease model of rats was produced by intracerebroventricular injection of A?_(25-35)(10 ?g,once).Morris water maze was used to measure spatial memory performance.Nissl staining and immunohistochemical technique for glial fibrillary acidic protein(GFAP) were employed to determine the morphology of pyramidal neurons and astrocyte infiltration in hippocmpal CA1 regions.The levels of phospho-p38MAPK and IL-1? were determined by Western blot and ELISA method.Reverse transcription-PCR analysis showed changes in FasL mRNA.Results Intracerebroventricular injection of A?_(25-35)in rats resulted in spatial memory impairments shown by longer escape latency and decreased percentage of time spent in the target quadrant.These behavioral dysfunctions were accompanied by astrocyte activation and infiltration,increased IL-1? production and elevated FasL mRNA level,the loss of pyramidal neurons in hippocampal CA1,and the increase of phosphorylated p38MAPK.Oral administration of sodium ferulate(50,100,250 mg?kg~(-1)daily) and ibuprofen 15 mg?kg~(-1)daily markedly improved the memory impairment,attenuated pyramidal neuronal damage,and reversed the A?-induced increases in IL-1? and p38MAPK activation.Conclusion sodium ferulate prevents A?-induced neurotoxicity through suppressions of inflammatory response and the activation of p38MAPK.

The antifungal antibiotic produced by Streptomyces luteogriseus H-103 was purified by means of macroporous adsorbent resin, and the crystal of the antibiotic with high purity was got. In this paper, the methods of purification by adsorbing of microporous adsorbent resin and detection by reversed high performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) were established. The result appeared that resin X-5 is the best adsorbent, the eluant is 50% ethanol. The antibiotic was successfully separated on Agilent~(TM)20RBA?310SB C_(18 )column (150mm?4.6mm i.d,5?m) , using a mixture of acetonitrile (A)-H_(2)O (B) as a mobile phase under gradient elution at a flow of 0.8mL/min at 30℃.0~4.0 min, V(A)∶V(B)=20∶80, 4.0~9.5min, V(A)∶V(B)=45∶55, then V(A)∶V(B)=80∶20. The drift tube temperature and the air carrier gas flow rate of the ELSD were set at 115℃ and 2.3L/min.

AIM To explore the mechanism of amyloid β-protein fragment 25-35(Aβ25-35)-induced inflammation and apoptosis in rat hippocampus in vivo by studying mitogen-activated protein kinase (MAPK) signaling pathway and the protective effect of anti-inflammatory drug ibuprofen. METHODS Rats were given ibuprofen (7.5 mg·kg-1 daily, ig) for 3 weeks prior to and 1 week after icv single dose of Aβ25-35 (10 μL, 1 mmol·L-1). Seven days after injection, Nissl staining and immunocytochemical technique were employed to determine the morphology of pyramidal neurons and astrocyte infiltration in hippocampal CA1. The expressions of IL-1β, extracellular signal-regulated kinase (ERK), p38 MAPK, PKC, and caspase-3 were determined by Western blot. Reverse transcription-PCR analysis showed changes in IL-1β mRNA level. RESULTS Intracerebroventricular injection of Aβ25-35 elicited astrocyte activation and infiltration and caused a strong inflammatory reaction characterized by increased IL-1β production and elevated IL-1β mRNA level. The inflammatory reaction was accompanied by the loss of pyramidal neurons in hippocampal CA1. The phosphorylation of p38 MAPK was significantly increased, on the other hand, the phosphorylation of ERK was significantly reduced and these were coupled with the increase of caspase-3 expression in hippocampal CA1. Ibuprofen (7.5 mg·kg-1 daily, 4 weeks) significantly reduced Aβ-induced IL-1β expression, caspase-3 expression and p38 MAPK activation. The loss of pyramidal neurons was also significantly attenuated by treatment with ibuprofen. CONCLUSION The activation of p38 MAPK and the down-regulation of ERK play a pivotal role in the inflam-matory response and apoptosis evoked by Aβ25-35 in vivo, which can be prevented by ibuprofen.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective To explore the changes of hydrogen sulfide(H2S) levels in plasma of newborn infants with pulmonary hypertension(PH) and its relationship with pulmonary hypertension,and provide scientific evidence for the decision of treating neonatal PH.Methods Sixteen children with PH and 16 children without PH in ICU from Mar.2005 to Mar.2006 were selected.Ultrasonic cardiogram(UCG) examination was performed for eachpatients.Pulmonary artery pressure(PAP) was measured.The plasma concentrations of H2S,cysteine and PAP of each patient were measured.Results PAP was 4.27-9.73 kPa[(6.49?1.79) kPa] in neonatal PH group,and PAP in control group was normal.The plasma levels of cysteine and H2S in neonatal PH group significantly increased compared with those of control group [(11.94?6.65) ?mol/L vs(6.43?2.08) ?mol/L,t=2.630 P=0.016;(26.99?1.33) ?mol/L vs(24.92?1.36) ?mol/L,t=4.373 P=0].Conclusions Endogenous H2S and cysteine were up-regulated during the development of neonatal PH;it might play an improtant role in the development of PH.H2S possibly depress the PAP by dilating the pulmonary artery to protect the patients with pulmonary hy pertension.

0.05).The different tilt angles impacted patients' fear psychology(?2=8.038,P=0.018).The order of the extent of children's fear psychology represented from low to high at the angle of 60?,70? and 80?,respectively.The extent of the children's fear psychology had positive correlation with the tilt angle(r=0.669,P=0.002).Conclusions The tilt test angle does not affect the positive rate of HUTT and the hemodynamics in children undergoing HUTT with angles from 60? to 80?.The children at the tilt angle 60? had less fear than at the angle of 70? or 80?.The 60? tilt angle of HUTT in children is recommended in the clinical practice.
