Objective To investigate the clinical curative effect of salmeterol fluticasone asthma and its in-fluence on lung function,serum CRP.Methods 202 cases of asthma patients were divided into the observation group and control group,with 101 cases in each group.The control group patients simply give fluticasone propionate inhala-tion therapy,the observation group patients were given salmeterol fluticasone inhalation therapy.Before and after treat-ment in patients with two groups of curative effect and treatment of pulmonary function,the change of serum CRP were compared.Results The total effective rate of the observation group was 92.1%,which was higher than the control group (78.2%)obviously,the difference was statistically significant(χ2 =3.842,P<0.05 ).After treatment,the forced vital capacity(FVC),forced expiratory volume in first second(FEV1 )and the maximum peak expiratory flow (PEF)of the observation group were respectively (84.11 ±16.25 )%,(96.34 ±19.65 )% and (93.14 ± 17.85)%,and the control group were respectively (74.31 ±14.27)%,(84.36 ±20.31)% and (83.52 ± 19.89)%,each group was obviously improved than before treatment,and the observation group improvement were better than the control group,the difference was statistically significant(t=3.425,2.573,2.895,all P<0.05).After treatment,the CRP of the observation group was (18.94 ±3.46 )mg/L,and the control group was (10.34 ± 1.97)mg/L,each group was obviously improved than before treatment,and the observation group improvement was better than the control group,the difference was statistically significant(t=2.874,P<0.05 ).Conclusion Salmet-erol fluticasone inhaled asthma can significantly improve the clinical curative effect to improve the patient's lung func-tion and serum CRP level,and is safe and reliable.It is worth widely application in the clinical practice.

Objective To study the clinical efficacy and effects on CRP levels of ambroxol in treatment of pulmonary infections.Methods 68 patients with pulmonary infection were selected and divided into the observation group(n =34)and control group by using the random number table method(n =34).The observation group was treated with ammonia bromine atomization inhalation treatment,while the control group was treated with alpha chymo-trypsin atomization inhalation therapy.The clinical effect and duration of symptoms and signs disappeared of the two groups were compared,and serum CRP level changes in the two groups before and after treatment were also compared. Results After treatment,the clinical total effective rate was 91.2% of the observation group.And the total effective rate was 70.6% in control group,the comparison between the two groups had statistically significant difference (χ2 =4.316,P <0.05).Compared with the control group,the observation group patients symptoms disappear time(3.1 ± 0.5)d,pulmonary symptoms disappear time(4.1 ±1.7)d,body temperature returned to normal time(4.1 ±1.6)d and hospital stay(8.4 ±2.8)d were significantly shortened,the differences were statistically significant (t =2.879, 2.918,3.025,3.972,all P <0.05 ).The serum CRP levels in patients of the observation group was (22.45 ± 9.27)mg/L,which of the control group was (33.45 ±14.67 )mg/L,both were significantly lower than before treatment,the difference was statistically significant (t =6.314,5.126,all P <0.05).The lower degree of serum CRP level in the observation group was obviously better than tha in the control group,the difference was statistically significant (t =6.263,P <0.05).Conclusion The ambroxol can achieve significant clinical effect on treatment of pulmonary infections,which can significantly shorten the patientˊs symptoms and lung signs disappear time and length of hospital stay,etc.It can reduce the serum CRP level,and is worth popularization and application in clinic.

Objective Drug-induced immune thrombocytopenia (DITP) is a major adverse drug effect mediated by drugdependent antibodies.It can be actuated by a wide range of medications,including Rifampicin.Methods Rifampicin-dependent antibody (rd-Ab) from a rifampicin-treated tuberculosis patient with thrombocytopenia (RITP) was characterized by in vitro and in vivo assays,which includes flow cytometry,monoclonal antibody immobilization of platelet antigens (MAIPA) assay,platelet aggregation assay and RITP mouse model.Results The rd-Ab could bind glycoprotein (GP) Ⅱ b/Ⅲ a,as shown by the MAIPA assay.The binding of rd-Ab could be blocked by AP2,a monoclonal antibody that binds a calcium dependent site on GP Ⅱ b/Ⅲ a complex and inhibits ADP-induced platelet aggregation.These results suggested that rd-Ab binds the same site or proximal sites on the GP Ⅱ b/Ⅲ a complex as AP2.Furthermore,the rd-Ab inhibited platelet aggregation in vitro.In an established NOD/SCID mouse model of RITP,the rd-Ab caused a rapid clearance of human platelets (MPL=1.1 ± 0.2h).The in vivo platelet loss could be partially prevented by treatments with intravenous immunoglobulin (IVIG) or corticosteroids (MPL=4.7 ± 0.7h and 4.2 ± 1.1h,P＜0.05).Slowing of platelet clearance was observed immediately upon IVIG treatment,while upon corticosteroid treatment at 24h,and reaching its peak at 72h.Combination of IVIG and corticosteroid treatments was more efficacious (MPL=6.2 ± 1.5h,P＜0.05).Conclusions 1.The rd-Ab binds to calcium-dependent-epitopes on the calcium dependent site of GP Ⅱ b/Ⅲ a complex,which causes platelet damage and inhibits platelet aggregation.2.Either IVIG or corticosteroid alone can partially block platelet clearance by rd-Ab.Slowing of platelet clearance is observed immediately upon IVIG treatment,or upon corticosteroid treatment several days later,indicating that IVIG may be more suitable for acutely raising the platelet count than corticosteroid treatment for RITP.3.Combination of IVIG and corticosteroid treatment is more efficacious than IVIG or corticosteroids alone.

Objective:To explore the mechanism for immunomodulatory activity of Astragalus polysaccharide (APS) with peripheral blood mononuclear cells(PBMC)-derived plasmacytoid dendritic cells (pDCs) from healthy volunteers.Methods:Healthy volunteers-derived pDCs were sorted by flow cytometry,then incubated with APS (0m50,100,200 mg/L ).After 24 hours,the concentration of IFN-?,TNF-?,IL-6 was detected using ELISA.After 5 days,the cultured cells were collected and analyzed by flow cytometry,light microscope and electron microscope scanning.Results:APS-treated pDCs secreted higher level of IFN-?,TNF-?,IL-6.APS could promote differentiation of pDCs to dendritic cells (DCs) which displayed more matured morphology and immunophenotypes compared to the untreated-pDCs.Conclusion:APS could increase the immune function of pDCs,promote differentiation and maturation of pDCs.
