Objective To investigate the changes of serum immunoglobulin E(IgE)?T cell subgroups and cytokines in asthmatic children and to provide theoretical basis for the management of asthmatic children.Methods T cell subgroups were determined by indirect immuofluorence method mono clone antibody, the detection of IgE,interleukin(IL) 4,IL 6,IL 8,interferon ?(IFN ?) were done by ELISA method, and 20 normal children were served as control group.Results There were significant differences of CD3 +,CD4 +,CD4 +/CD8 + among the stages of exacerbation and convalescence of asthmatic children and control group.( P0.05).In the stage of convalescence the levels of IL 2,IFN ? were lower than control group( P0.05).Conclusions Allergic asthmatic patients between the exacerbation and convalescence stages still had immunologic imbalance,indicating increased number of CD4 +T cell(mainly Th2 cells)and hyperfunction;the insufficient number and(or) the inactivity of CD8 +T cell may induce immunological disturbance ,which is the major mechanism of asthmatic attacks. These findings suggest the patients in an abnormal immunological state should receive continuous anti allergic therapy.

Objective To explore the liver pathology from live related liver transplatation(LRLT) of Wilson′s disease(WD) in children,and evaluatethe indication of LRLT.Methods The sample of this study,including the donater and patient,came from the LRLT. It was observed with HE,MASSON,Timm′s and Rubeanic staining.Results With HE and MASSON stainning,hepatocyte showed degeneration,fiber hyperplasic and false lobule formed;Timm′s and Rubeanic stainning showed typical black deposit of granules and conglomerations.Liver pathology revealed that liver cirrhosis appeared,and it was diffrentent from Child Pugh.Conclusions It is of great significance that the liver pathology is useful for the treatment of WD.If liver pathology supportes,the indication of LRLT can be measurably broadened.

Hippophae rhamnoides is one of the most representative economy crops for its wide uses of biological diversity and abundance of resource. As the key healthy food development and ecology protection, H. rhamnoides has been developed widely. Meanwhile, the development of H. rhamnoides has obtained great achievements. Nowadays, H. rhamnoides is still a necessary economy crop, while it has great influence on ecology protection. This paper discussed the phytochemistry, pharmacology, clinical application and product development, and propounded some suggestions for future research and economy development to get comprehensive benefit of H. rhamnoides and to serve for well-off society.

Objective To investigate whether there is prethrombotic state in acute viral encephalitis.Methods Von willebrand factors (VWF),granule membrane protein-140(GMP-140) and D-dimer were measured in 60 children,30 cases of them had mild acute viral encephalitis, and other 30 cases of them had severe acute viral encephalitis.Results The figures mentioned above had marked difference in children with mild acute viral encephalitis during acute and recovery stage compared with controls.Conclusions Testing the expressive rate of GMP-140 on platelet surface,plasma VWF and D-dimer can find the prethrombotic state immediately. GMP-140,VWF and D-dimer in estimating the severe extent of disease and the prognosis play a major role. J Appl Clin Pediatr,2004,19(6):501-503

The impact of key physical properties on granulated products by the high-speed mixing wet method was studied. Andrographis extracts were utilized as the model drug. Four processing methods were adopted to prepare mixed powder of microcrystalline cellulose (MCC) and starch with the mass ratio 1:0.5, 1:1 and 1:2 by the high-speed mixing wet method. The properties of the prepared granules were evaluated with such indexes as granule yield, the ratio of lumps and fine powder, granule-AOR and granule-HR. The impact of key physical properties on granulated products was analyzed through stepwise regression analysis. The results showed that angle of repose, moisture content, pore volume, density and contact angle with water were key physical properties of the powder. The key physical properties of Chinese medical extracts powder are the important factor impacting granulated products made by the high-speed mixing wet method. In this study, the impact of key physical properties on granulated products of Chinese medical extracts was analyzed from the physical angle.

Objective To invesgate the safety and efficacy of the second generation biodegradable polymer Cobalt-Chromium sirolimus-eluting stent (EXCEL2) stent in diabetic patients by a subgroup analysis of of the CREDITⅡand CREDIT Ⅲ trials. Methods All patients who were implanted with the EXCEL2 stent were enrolled in the CREDITⅡand CREDIT Ⅲ trials. The primary endpoint was target lesion failure at 24-month, defi ned as a composite of cardiac death, target vessel myocardial infarction (TV-MI) and target lesion revascularization(TLR). The secondary endpoint was endpoints including all-cause death, all myocardial infarction (MI) or any revascularization.Results A total of 828 patients were included from the patients who were implanted with the EXCEL2 stent in the CREDIT II and CREDIT Ⅲ trials. 24-month follow-up rate was 99.5%. There was no significant difference in the primary endpoint (P>0.05) and event rates of the secondary endpoints(P>0.05) between the diabetic and non-diabetic group, which included all-cause death[diabetics (2.5%)vs.non-diabetics(1.4%),P>0.05],myocardial infarction(MI)(7.5% vs.5.0%,P>0.05),all from of revascularization(5.0% vs.3.9%,P>0.05),and stent thrombosis(0.6% vs.0.4%,P>0.05).Conclusions EXCEL 2 stent met the objective performance goal on effcacy and safety, which can reduce make stent restenosis, target vessel revascularization ,with 160 diabetic cases among them, and stent thrombosis in diabetic patients.

Plant active components characterized of many different structures and activities on multiple targets, have made them to be the important sources of inhibitors on HIV-1. For finding leading compounds with new structure against HIV-1, three key HIV-1 replicative enzymes (reverse transcriptase, protease and integrase) were used as screening models. The in vitro activities of 45 plant derived components isolated from Schisandraceae, Rutaceae and Ranunculaceae were reported. Within twelve triterpene components isolated, eight compounds were found to inhibit HIV-1 protease, in these eight active compounds, kadsuranic acid A (7) and nigranoic acid (8), inhibited both HIV-1 protease and integrase; Among fifteen lignans, meso-dihydroguaiaretic acid (15) and kadsurarin (16) were active on HIV-1 reverse transcriptase, and 4, 4-di(4-hydroxy-3-methoxyphenly)-2, 3-dimethylbutanol (13) active on HIV-1 integrase. All of the six alkaloids, seven flavones, and five others compounds were not active or only with low activities against HIV-1 replicative enzymes. Further studies of the triterpene components showing strong inhibitory activities on HIV-1 were warranted.

TNKSs are members of poly ( ADPribose) polymera-ses, which are different from other members of the PARP family with two unique structures: SAM domain and ankyrin repeat re-gion. TNKS participates in a variety of cellular function regula-tion, including telomere’ s dynamic balance, Wnt signaling pathways, glucose metabolism and spindle formation during mi-tosis. TNKS, as a very attractive drug target, regulates the sta-bility of target proteins via poly ( ADP-ribosylation). In recent years, the significant progress has been made for PARP inhibi-tors in cancer treatment. Multiple PARP inhibitors have entered different clinical evaluation stages. AstraZeneca's Olaparib, Clo-vis's Rucaparib, Merck's Niraparib come into existence in the market. This paper summarizes the recent studies of TNKS and its related inhibitors.
