Objective To explore the clinical significance of detection of IL-17 and peripheral blood eosinophil(EOS) count in whee-zing children under 5 years old.Methods Fifty-three children with recurrent wheezing under 5 years old had been randomly enrolled including 43 boys and 10 girls.They were divided into 2 groups :wheezing group Ⅰ,in which,the patients with atopic high risks(n=27);whee-zing group Ⅱ,in which,the patients without atopic high risks(n=26).Children without infectious diseases such as hernia and renal calculus had been enrolled randomly as control group(n=20),including 11 boys and 9 girls.After taking 3 mL venous blood and centrifuging of patients in 3 groups,the level of IL-17 in the serum was measured by double-antibody sandwich enzyme-linked immunosorbent assay,peripheral blood EOS count was performed in the meantime by means of eosine staining.Results The serum levels of IL-17 in wheezing groups [(1 469.315?978.300) ng?L-1,(263.340?131.800) ng?L-1]were significantly higher than that of control group[(36.478?2.000) ng?L-1](Pa0.05);serum IL-17 and peripheral blood EOS count had positive correlation(r=0.933,P

Detection of serum tumor markers in clinical application is simple,which has become an in dispensable means in clinical medical work,and played an important role in the early detection of malignant tumor,benign and malignant tumor differential diagnosis,guiding the stage and predicting prognosis.But because of its sensitivity and specificity have limitations,we should find more new markers.

Objective To investigate the surgical indications and repair methods for the treatment of electrical bums in the limbs.Methods Thirty-eight cases since May,1997 to June,2014 who underwent flap treatment in 7-14 days after electrical bums was summarized.Among these patients,4 cases were treated by local flaps,1 case was treated by thenar flap,2 cases were treated by dorsal island skin flap of the index finger,1 case was treated by cross-leg flap,1 case was treated by medial plantar skin flap;2 cases were treated by pedicle latissimus dorsi flaps,4 cases were treated by antebrachial flap with a pedicle of the posterior interosseous artery,4 cases were treated by metacarpal artery reversed island flaps,10 cases were treated by groin flaps;1 case was treated by free radial artery flap,1 case was treated by free latissimus dorsi flap,3 cases were treated by free anterolateral thigh flaps;1 case was treated by reverse island forearm posterior interosseous flap,2 cases were treated by posterior perforator reversed island flaps of the lower leg,1 case was treated by anterolateral perforator reversed island flaps of the lower leg.The area of flap was from 42.0 cm × 13.0 cm to 6.0 cm × 3.0 cm.The survival rate of the flap,the appearance and function of limb were observed.Results All these patients were followed up from 4 months to 3 years 6 months,the mean time was 6 months and 20 days.Thirty-five flaps survived completely,accounting for 92.1%,and 3 cases suffered partial necrosis at the distal end,accounting for 7.9%.Secondary healing was achieved by dress changing.The appearance of the limbs was satisfactory.Among the 28 cases whose bums were on the hands,the total number of excellent and good was 15,medium was 8,and 5 poor cases.The excellent and good rate was 57.1%.Conclusion Early repairing of the electrical burns with flaps is the effective method for protecting the deep structures of the limb,preventing and control the secondary infections and preserve the function of the limbs.

Objective To explore the roles and possible mechanism of calcium-sensing receptor(CaSR) in cell cardiac hypertrophy model using angiotensin Ⅱ (Ang Ⅱ ).Methods The cultured neonatal rat ventricular myocytes were treated with Ang Ⅱ as cell cardiac hypertrophy model.Hypertrophic neonatal rat cardiomyocytes were treated with GdCl3(a specific agonist of CaSR) and/or with Ro318220(a specific inhibitor of PKC pathway).To evaluate the status of cardiac hypertrophy,cell diameter was observed by HE dyeing,and protein content was determined through coomassie brilliant blue protein kit.The intracellular calcium concentration( [ Ca2+]i) was determined by laser scanning confocal microscope.The protein expression of CaSR and PKC pathway were analyzed using Western blotting.Results ①Compared to the control group(0.1263 ± 0.0443),the protein expression of CaSR was increased in Ang Ⅱ group and in GdCl3 group(0.1963 ± 0.0375,0.2778 ± 0.0564,all P< 0.05).Moreover,compared with Ang Ⅱ alone,the increase was significant in GdCl3 group(P < 0.05).②Compared to control group(222.70 ± 22.09),AngⅡ group(392.16 ± 36.85) remarkably increased [Ca2+]i(P< 0.05),and this increase of [Ca2+]i was further enhanced in GdCl3 group (502.60 ± 44.21) versus Ang Ⅱ group (P < 0.05).③Compared to control group,Ang Ⅱ could induce cardiomyocyte hypertrophy,and GdCl3 enhanced the effect.Moreover,this enhancement was attenuated by Ro318220.④Compared to control group(0.27 ± 0.07,0.69 ± 0.06,0.87 ± 0.04),the protein expression of PKCα,PKCε and PKCδ was increased in Ang Ⅱ group(0.60 ± 0.16,1.02 ± 0.13,1.20 ± 0.18,all P< 0.05) and the protein expression of PKCα,PKCε was increased in GdCl3 group(0.82 ± 0.16,1.34 ± 0.12,all P < 0.05).Moreover,compared with Ang Ⅱ group,the protein expression of PKCα,PKCε was obviously increased in GdCl3 group (all P < 0.05);compared with GdCl3 group,the protein expression of PKCα,PKCε(0.41 ± 0.10,0.85 ± 0.14) was obviously decreased in Ro318220 group(all P < 0.05).Conclusions CaSR is involved in cardiac hypertrophy induced by Ang Ⅱ through PKC pathway in cultured neonatal rat cardiomyocytes.

ObjectiveTo explore the effect and safety of intravenous sodium valproate in treatment of pediatric patients with status epilepticus (SE).MethodsTwenty-five children suffering from convulsive SE were treated with intravenous sodium valproate after failure of the conventional treatment, in a dose of tolerability 15 mg/kg and 1~2 mg/kg daily.ResultsIn 25 cases, there were 23 cases (92%) with ≥50% seizure reduction and 11 cases (44%) with complete cessation. Except for winking in 7 cases (28%), no other adverse effects had been found.ConclusionIntravenous sodium valproate is effective and safe on pediatric patients with SE who are resistant to conventional drugs.

Since 2000,most of H5N1 subtype influenza A virus had a unique mutation of NS gene with 15base pair deletion from 263 to 277. In order to investigate the bio-characteristics of this mutation,two different NS recombinants,RWSN-248 and RWSN-m248,were generated via plasmid rescue from A/WSN/33(H1N1) and A/SD/04(H5N1). RWSN-248 had a higher viral titer than RWSN-m248 in MDCK and COS-1 cells that have an IFN response,but they had the similar growth ability in Vero cells that lack an IFN response. Both of two recombinants grew well in embryonated chicken eggs and had the similar viral titer and MDT. The results above revealed that the deletion from 263 to 277 sites of NS gene did not influence viral virulence to but decreased viral anti-IFN ability of H5N1.
