Objective To discuss the influence of different doses budesonide aerosol inhalation on serum cytokines levels in children with severe asthma.Methods 96 children with severe asthma aged 4 to 14 years old in our hospital were chosen,and they were randomly divided into the observation group and the control group,48 cases in each group.All patients were given conventional treatment, and the control group was given 1mg/time budesonide treatment on the basis of conventional treatment (3 times a day),while the observation group was given 2mg/time budesonide treatment (3 times a day).Before and 1 week after treatment,the clinical symptoms of two groups were observed and compared,as well as the changes of IL-4,IFN-gamma,IL-10 and TNF-α.Results In the obser-vation group,wheezes,coughing,wheezy sound and rales disappearance time were (2.10 ±0.77)d,(5.45 ±1.20)d, (3.46 ±1.03)d,(5.55 ±1.35),which were significantly shorter than (2.98 ±1.02)d,(7.48 ±1.19)d,(5.43 ± 1.06)d,(7.56 ±1.67)d in the control group (t=4.77,8.32,9.23 and 8.32,all P<0.01).4 weeks after treat-ment,the total effective rate of the observation group was 89.6%,which was significantly higher than 72.9% of the control group (χ2 =4.376,P<0.05).After treatment,the IL-4,IL-10,TNF-alpha,IFN-gamma levels in the observation group were (4.06 ±1.77)pg/mL,(12.77 ±2.05)pg/mL,(4.15 ±1.11)ng/mL,(26.23 ±2.78)pg/mL, which had significant changes compared with (9.02 ±2.23)pg/mL,(10.21 ±1.30)ng/mL,(6.66 ±1.62)pg/mL, (17.33 ±2.31)pg/mL before treatment(t=12.07,24.56,16.20,17.25,all P<0.01).After treatment,the IL-4, IL-10,TNF-alpha,IFN-gamma levels in the control group were (9.11 ±2.05)pg/mL,(6.80 ±1.23)ng/mL, (9.88 ±2.20)pg/mL,(21.22 ±2.80)pg/mL,which had significant changes compared with (9.11 ±2.05)pg/mL, (10.38 ±1.37) ng/mL,(6.71 ±1.77) pg/mL,(17.30 ±2.05) pg/mL before treatment( t=5.36,13.47,7.77, 7.83,all P<0.01).But IL-4,TNF-alpha levels in the treatment group were significantly lower than those in the control group (t=7.32,11.08,all P<0.01),while IL-10 and IFN-gamma levels were significantly higher than those in the control group (t=6.65,8.80,all P<0.01).The incidence of adverse reactions of the two groups had no statistically significant difference (χ2 =0.771,P>0.771).Conclusion High doses of budesonide aerosol inhalation in the treatment of children with severe asthma has obvious clinical curative effects,which could significantly improve the patients'clinical symptoms,and also has low incidence of adverse reactions,which is worthy of clinical promotion.

Objective:To re-establish the quality control standard for Weiling granules. Methods:The 4 chief herbs in the prepa-ration, radices paeoniae alba, licorice, rhizoma corydalis and hawthorn were identified by TLC qualitatively. The content of paeoniflor-in in radices paeoniae alba was determined by HPLC. The separation was performed on an Agilent XDB-C18 (250 mm × 4. 6 mm, 5μm)coulme with mobile phase consisting of acetonitrile-0. 1% phosphoric acid solution (10:90). The detection wavelength was 230 nm and the flow rate was 1. 0 ml·min-1 . Results:The spots in TLC were clear without any interference. The linear range for paeoni-florin was 0. 151-1. 212 μg(r=0. 999 9,n=5). The average recovery was 99. 63% and RSD was 2. 01%(n=9). Conclusion:The method is simple and accurate with high reproducibility, which can be used for the quality control of Weiling granules.

Objective To survey prevalence of behavior problems in children of off-farm workers and effects of family factors on children' s behavior problems.Methods The study was done in the whole 7 schools for off-farm workers' children in Shanghai Baoshan district,including all 3 ～ 6 grades students of primary school and 1 ～3 grades students of junior high school.Totally 4350 students finished survey (95.4％).Achenbach' s child behavior checklist ( CBCL,parent' s version) and general family questionnaire were used.Results ( 1 ) Prevalence of behavior problems in children was 11.2％ ; 12.8％ 12 ～ 16 years children had behavior problems( 14.7％boys and 10.4％ girls) ; 11.4％ of one-child children had behavior problems compared with that of 11.2％ child with siblings children ( x2 =0.038,P ＞ 0.05 ).(2) Total score ( 20.64 ± 17.67 ) and factor scores of thought problems,depressed,hyperactivity,delinquent rule-breaking behavior were higher than those of Chinese norm (P ＜0.05 or P ＜ 0.01 ) among 6 ～ 11 years boy group.Total score ( 17.23 ± 14.73 ) and scores of thought problems,depressed,social problems,hyperactivity,delinquent rule-breaking behavior were higher than those of Chinese norm (P ＜ 0.01 ) among 6 ～ 11 years girl group.Among 12 ～ 16 years boy group,total score (20.44 ± 19.32) and all factor scores of CBCL were higher than those of Chinese norm(P＜0.01 ).Total score ( 17.02 ± 16.72) and scores of immature,delinquent rule-breaking behavior,brutality were higher than those of Chinese norm(P ＜ 0.05 or P ＜0.01 ) among 6 ～ 11 years girl group.(3)Multi-regression analysis showed that poor parent-child relationship was the most important predict factor for higher score of CBCL among all family risk factors (P ＜ 0.05 ).Conclusion Children of the off-farm workers and their families need special mental health care program.

Objective To explore the changes of deceleration capacity of rate (DC) and analyze its correlation with heart rate variability (HRV) and other factors in patients with coronary heart disease. Methods One hundred and twenty-nine patients with coronary heart disease (coronary heart disease group) and 109 healthy people (control group) were enrolled in this study. DC and HRV parameters were measured by using digitized 24 h Holter. The correlation between DC and HRV parameters, other factors were analyzed. Results The levels of DC, SDNN, SDANN, SDNNi, PNN50, TP, LF, HF, AC in coronary heart disease group were significantly lower than those in control group:(5.64±1.67) ms vs. (6.71±1.47) ms, (106.60±20.53) ms vs. (138.82±31.22) ms, (96.94±20.06) ms vs. (127.47±31.87) ms,(28.53±14.75) ms vs. (52.24±14.65) ms, 87.72%vs. 103.86%,(1 967.10±966.16) ms2/Hz vs. (2 846.70±1 443.41) ms2/Hz,(326.43±195.35) ms2/Hz vs.(457.64±254.30) ms2/Hz, 85.88 vs. 106.39, (-6.18±2.15) ms vs. (-7.00±2.51) ms, P<0.05 or<0.01. DC was correlated with SDNNi, PNN50,TP,LF, HF, AC both in total population or in coronary heart disease group and control group by using multiple linear correlation analysis ( r=0.586, 0.356, 0.531, 0.563, 0.435,-0.433, P<0.01). After removing confounders, DC was correlated with age, SDNNi, rMSSD, PNN50 and AC (P<0.01). Conclusions DC decreases in patients with coronary heart disease and is strong correlativity with HRV parameters. DC could be used for quantitative detection of autonomic nervous function.

The biological!activities i.e. antineoplastic activities and antiviral activity of the two novel kinds of interferons: hIFN-?1 and hIFN-? were studied and compared. First the fusion expression vector: pcDNA3.1A-hIFN-?1-His and pcDNA3.1A-hIFN-?-His by PCR was constructed,then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFN-?1-His and rhIFN-?-His, meanwhile MTT assay was used to detect their antineoplastic activities.It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-?1-His is more powerful than of rhIFN-?-His. The antiviral molecular mechanisms of both hIFN-?1 and hIFN-? are related to MxA.The foundation for further study on the bioactivities and mechanism of action of hIFN-?1 and hIFN-? was established.

The known members of inhibitor of growth (ING) gene family are considered as candidate tumor suppressor genes. ING4, a novel member of ING family, is recently reported to regulate brain tumour angiogenesis through transcriptional repression of NF-?B-responsive genes, induce G2/M arrest by the increased p21 expression in a p53-dependent manner, suppress the loss of contact inhibition and represses activation of the hypoxia inducible factor, which plays an important role in the progression of tumorigenesis. However, seldom studies about ING4 inducing tumor cells apoptosis were reported.The C6 cells (mouse glioma cells) were infected respectively with the blank adenovirus carrying GFP (Ad) and the recombinated Ad-hING4-His, then RT-PCR assay was used to detect the transcriptions of hING4, as well Western-blotting assay was ued to detect the expressions of hING4. The effects of hING4 expression upon C6 cells were observed, and the growth curve was drawed and tumor control rates were calculated. The C6 cells, which were affected by blank Ad and Ad-hING4-His, were respectively observed by LSCM (laser scan confocal microscope) and transmission electron microscope (TEM), detected by flow cytometry; and the genomic DNA of both groups were extracted and electrophoresised in agarose gel to examinate the DNA fragments. The results showed hING4 can significantly inhibit the growth of C6 cells by promoting the cell’s apoptosis, which probably is the first one to prove this property of ING4.The experimental and theoretical foundation for gene therapy for gliomas with ING4 in the future was established.

ABSTRACT:Objective To explore the role of HIF‐1αin the pathogenesis of hepatopulmonary syndrome (HPS) and its relationship with GRP78 .Methods The HPS model in rats was induced by multiple pathogenic factor .The samples were assessed by using Western blotting analysis for HIF‐lα, GRP78 and VEGF164 .
