Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

In this paper, the RP-HPLC specific chromatography was adopted, with DIKMA-C18 (4.6 mm x 250 mm, 5 µm) as the chromatographic column, with a gradient elution compose of acetonitrile and 0.1% phosphoric acid at flow rate of 0.8 mL · min(-1), the detection wavelength was 220 nm. The difference of the HPLC specific chromatograms between the Lu Dangshen and other different base sources and different producing area of Codonopsis Radix was compared, involved in the similarities and differences of the number and the relative peak area of characteristic peaks in the HPLC specific chromatograms. The HPLC specific chromatograms of Lu Dangshen was established and the relative retention times of seven peaks was determined, and the peaks of codonopyrrolidium B, syringin, lobetyolin, tangshenoside I and atractylenoide III were identified; The HPLC specific chromatograms of Lu Dangshen provided a method for scientific evaluation and effective control the quality of Lu Dangshen from Shanxi famous-region.

Objective To explore the changes of plasma angiotensinⅡ (AngⅡ) and cardiac function,and the curative effect of children with acute viral myocarditis (VMC) treated with captopril(CAP).Methods Concentrations of plasma AngⅡ were measured with radio-immunity and cardiac function was detected by Doppler echocardiography for the VMC group (n=60) before and after treatment [the CAP group (n=30), the routine group (n=30) and the control group (n=30)].Results 1. The level of plasma AngⅡ significantly increased and the contractive and diastolic function obviously declined in children with acute VMC. There was a significant difference between VMC group and control group, with a significant correlation between the level of AngⅡand the contractive diastolic function.2. Compared with the level before treatment, the level of AngⅡ decreased and the contractive function obviously ameliorated in two groups; the diastolic function obviously ameliorated in the CAP group and did not ameliorate in the routine group after treatment. In CAP group the level of AngⅡ and the cardiac function significantly improved; there were statistical differences between the two groups after treatment.Conclusions 1.The increase of the plasma AngⅡ was an important factor for decrements of the contractive and diastolic function in acute viral myocarditis.2.It could decrease the concentration of plasma AngⅡ and ameliorate cardiac function in children with acute VMC treated with captopril,which was an effective therapy for acute VMC.

OBJECTIVE: To determine the effect of different doses of sufentanil on stress responses to tracheal intubation in patients undergoing heart valve replacement surgery. METHODS: Sixty patients undergoing heart valve replacement surgery were randomly divided into 4 groups (n=15). Before the tracheal intubation, patients received 10microg/kg fentanyl (Group A), 1microg/kg sufentanil (Group B ), 1.5micro/kg sufentanil (Group C), and 1.5microg/kg sufentanil (Group D), respectively, with midazolum and vecuronium intravenous injection. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded before the induction of anesthesia(T(0)), after the induction of anesthesia(T(1)), and at 1(T(2)), 3(T(3)), 5(T(4)), and 10 min after the tracheal intubation(T(5)). Rate-pressure product was derived from SBP and HR. Blood sugar was monitored at T(0), T(2) and T5. RESULTS: The SBP,DBP,MAP, HR and RPP at T(0) were not significantly different among the 4 groups (P>0.05). These parameters at T(1) were significantly lower than those at T(0) (P<0.01), but there was not significant difference among the 4 groups. The SBP, DBP, MAP in Group A increased significantly at T(2) and T(3) than those at T(1)(P<0.01 approximately 0.05), but were not significantly different than those at T(0)(P>0.05). The SBP,MAP in Group B,C,D at T(2) and T(3) were significantly lower than those in Group A (P<0.01 approximately 0.05 ). The SBP and MAP in Group D at T(4) were still lower than those in Group A (P<0.05). The HR at T(2) in Group A increased compared with that at T(1)(P<0.05),but was still lower than that at T(0). The HR at T(2) in Group B, C, and D was not significantly changed. The HR decreased significantly at T(2) in Group D compared with that in Group A(P<0.05), and the HR at T5 in Group A and D significantly decreased compared with that in Group B(P<0.05). The RPP at T(1) to T5 in Group B, C, and D significantly decreased compared with that at T(0)(P<0.01). The RPP at T(2) in Group A increased significantly compared with those in Group B, C, and D(P<0.01). The cases of using atropine during the induction and intubation in Group A,B,C, and D were 5(33.3%),0(0%),4(26.7%),5(33.3%),respectively, and the cases in Group B were significantly different compared with those in Group A and D(P<0.05). The change of blood sugar in Group A,B,C, and D was not significantly different(P>0.05). CONCLUSION Three doses of sufentanil may effectively control the stress responses to the tracheal intubation in patients undergoing heart valve replacement surgery, and the hemodynamics during the intubation at 1microg/kg is much more stable.

Multi-walled carbon nanotubes-tungsten oxide (MWCNTs-WOx) nanocomposites were fabricated on glassy carbon electrode (GCE) through a simple electrodeposition method,in which WOx were fabricated on MWCNTs. The morphology and constitution were characterized by field emission scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). Electrochemical characterization of modified electrode was done by electrochemical impedance spectroscopy (EIS). The cyclic voltammogram (CV)method was adopted to investigate the electrochemical behavior of dopamine (DA) on MWCNTs-WOx-modified glassy carbon electrode, and a new detection method for DA was developed by differential pulse voltammetry (DPV). The results showed that MWCNTs-WOx nanocomposites had obvious electrocatalytic effect on DA in phosphate buffer solution (pH=6.5). Under the optimized experimental conditions, the DA peak current demonstrated a good linear relationship with concentration in the range of 0.05-1.00 mmol/L, and the detection limit was 17 μmol/L(S/N=3). Effects of different experimental parameters on the response current of the modified electrode were investigated,and it was found that the prepared electrochemical sensor displayed good reproducibility,high selectivity and strong anti-interference ability. UA did not interfere with the detection of DA. A new electrochemical method for the quantitative determination of DA was established and successfully applied to the determination of dopamine hydrochloride injection samples.
