ABSTRACT
Objective To investigate the correlation between serum interleukin-8 (IL-8 )and immunoglobulin/complement 3A (IgA/C3)and immune imbalance in Henoch-Schonlein Purpura(HSP)in children,and provide evidence and guidance for clinical therapy of HSP.Methods Serum IL-8 was measured by Enzyme-linked immunosorbent assay(ELISA),and IgA and C3 were de-tected by automatic biochemistry analyzer,and calculate the ratio of IgA/C3.Results Serum IL-8 levels were (389±5 1.68)ng/L, significantly higher than that in healthy children (P < 0.05 ).Serum IgA levels were(306.2 ± 32.21 )mg/L,significantly higher (P <0.05).Serum C3 levels were (1 14.5 ±20.7)mg/L,of no statistical difference.IgA/C3 were (3.041 ±0.508 5),significantly higher(P <0.05).There was a positive correlation between IL-8 and IgA/C3 (r =0.534,P <0.05 ).Conclusion The children of HSP has cytokine and immunoglobulin disturbance,and presents a hyperreactivity in both humoral immunity and cellular immunity. Positive correlation between IL-8 and IgA/C3 was observed.
ABSTRACT
OBJECTIVE To enhance the positive rate of the blood culture in order to make pathogenic diagnosis actually and quickly and conducting usage of antimicrobial agents in clinic.To value the clinical applied circumstance of BacT/Alert 3D automated blood culture system.METHODS The 3728 blood cultures were detected by BacT/Alert 3D automated blood culture system,and bacterial susceptibility test was conducted on all isolates using Kirby-Bauer methods with CLSI standards.To statistically analyze the examined time,the positive rate and variety and drug resistance for all kinds of pathogens.RESULTS The blood culture positive rate was 6.0% in the 3728 blood cultures with 222 strains of bacteria.The false positive rate was 0.2% and the false negative rate was 0.4%.The positive rate of blood culture was 0.89% in 12 hours,2.01% in 18 hours,and 3.51% in 24 hours.Among all the 222 isolates,29.7% were Enterobacteriaceae,the drug resistant rates to amikacin,ceftazidime,ciprofloxacin,and imipenem were 13.6%,36.3%,42.4%,and 3.0%,respectively;20.3% were Staphylococcus,the drug resistant rates to erythromycin,levofloxacin,cefoxitin,and vancomycin were 75.6%,33.3%,68.9%,and 0,respectively;11.7% were Enterococcus,the drug resistant rates to errythromycin,levofloxacin,fosfomycin,and vancomycin were 96.2%,80.8%,23.1%,and 0,respectively;11.3% were non-fermented bacilli,the drug resistant rates to amikacin,ceftazidime,ciprofloxacin,and imipenem were 32.0%,52.0%,32.0%,and 32.0%,respectively;12.6% were fungi.CONCLUSIONS The pathogens in the blood specimens are more wider in distribution and more higher in drug resistance rates than before.BacT/Alert 3D automated blood culture system can be an important tool for the blood culture,it can provide the diagnostic help quickly for the clinic and increase the positive rates in blood culture.It can not only shorten the check-up time,but also be more quick and more exact.
ABSTRACT
It has been found that Ginsenoside exhibits extensive pharmacological effects on animal and human.However,there have been few reports on these effects of Panax Quinquefolius saponin (PNS)so far.In this paper the immunologic effects of PNS were studied.Ⅰ.Immunologic effects of PNS on the immune cells of mice in vitror.The results showed that PNS could enhance ConA-induced splenocyte proliferation of mice,with the optimal concentration of lug/ml,The lymphokine(IFN,IL-2)production of splenocytes stimulated by ConA,and NKC activity of splenocytes also increadsed under the presence of PNS.Ⅱ.Effects of PNS on the immune function of mice in vivo The enhancement of spontaneous thymocyte proliferation,ConA-induced proliferation of splenocytes and thynocytes,ConA-induced production of IFN and IL-2 of splenocytes,NKC activity of splenocytes,and primary antibodyresponse to SRBC were examined.With the injection of PNS(1-2mg/20g/day)subcutaneously into mice for 7 days,
