Objective To study the different effects between intermittent eliminating white blood cells and immunosuppressive agents pulse therapy in children′s anaphylatoid purpura nephritis on the base of hormone′s treatment.Methods Twelve cases of anaphylatoid purpura nephritis were enrolled in the study and divided into 2 groups.After failure in the hormone′s treatment,the observation group was applied with intermittent eliminating white blood cells(5 mL/kg,1-2 times/week),and the control group was treated with immunosuppressive agents[cyclophosphamide(CTX) 0.8-1.0 g/m~2,or methotrexate(MTX) 8-10 g/m~2].Results There were no significant differences between the 2 groups.The observation group had no obvious side effects,but the control group all had different side effects.Conclusion The treatment of intermittent eliminating white blood cells can have better effects without the side effect resulting from immunosuppressive agents.

Objective To investigate the influence of coxsackie B virus (CVB) and mycoplasma pneumoniae (MP) superinfection on immunological manifestation of recurrent respiratory tract inflammations(RRI) in children.Methods One hundred and thirty-two hospitalized children with RRI between Jan.to Dec.2005 were divided into negative control group,MP infection group,CVB infection group and superintection group by determining anti-MP IgM and anti-CVB IgM.Blood sedimentation,C-reactive protein,IgG,IgA,IgM and T lymphocyte subpopulation etc.were determined in four groups.The anti-MP IgM was determined by specificity immune agglutination test.Enzyme linked immunosorbent assay was used to detect anti-CVB IgM.The IgG,IgA,IgM were determined by simple agar diffusion method.T lymphocyte subpopulation was tested by flow cytometry.Results The percentage of CVB infection was 32.1%,mainly expressed in the 1-3 years old children;the percentage of MP infection was 22.7%,mainly expressed in children over 3 years old.In both CVB and MP infection group,the ten-dency of IgG increased and that of IgA decreased.IgM in the CVB and MP superinfection group was obviously higher than that in negative control group and MP infection group (Pa

Objective To evaluate the susceptibility of itraconazole-resistant Aspergillus fumigatus isolates to four other antifungal drugs.Methods Six strains of Aspergillus fumigatus were serially isolated from a patient with lung aspergilloma,who was resistant to itraconazole therapy.Clinical Laboratory Stan- dard Institute broth microdilution method M38-A and E-test were applied to test the susceptibility of A.fumi- gatus strains to amphotericin B,itraconazole,voriconazole,caspofungin and micafungin.Results With M38-A method,the minimal inhibitory concentration(MIC)of itraconazole was 0.5?g/mL for 2 strains and more than 16?g/mL for the other 4 strains;the MICs of amphotericin B and voriconazole were 1?g/mL and 0.25-1?g/mL respectively for all the 6 strains;and the minimal effective concentration(MEC)of caspofungin and micafungin were no more than 0.03?g/mL for all the 6 strains.Moreover,E-test results also revealed that caspofungin and voriconazole had a good antifungal activity against all the strains,including the 4 itraconazole-resistant ones.Conclusion The itraconazole-resistant A.fumigatus strains isolated from a patient with lung aspergilloma are susceptible to amphotericin B,voriconazole,caspofungin,and micafungin.

Objective: To understand the relationship between coxsackievirus B and pediatric diseases. Methods: The infectious state of coxsackievirus B in hospitalized children were studied. Among 796 children studied, there were 218 upper respiratory tract infection cases, 179 pneumonia, 106 asthma, 155 myocarditis, 19 allergic purpura and 89 other diseases. The antigen (CVB-Ag) and IgM (CVB-IgM) were detected using ELISA method. Results: (1)There were 47% positive of CVB in upper respiratory tract infection and 48% positive of CVB in pneumonia(no difference between them, P>0.05). (2) There were 62% positive of CVB in asthma, 61% positive of CVB in myocarditis and 68% positive of CVB in allergic purpura(no difference among them, P>0.05)； But the positive rate of CVB in asthma, myocarditis and purpura were higher than in upper respiratory tract infection and pneumonia, (P<0.05). (3) There were lower positive rate of CVB in other kinds of diseases (16%) and in healthy children (3%)(no difference between them, P>0.05). Conclusion: CVB infection was related to several kinds of diseases, the relationship between CVB infection and diseases such as asthma, myocarditis, and allergic purpura should be further studied.

AIMTo find derivatives of p-methyl-goniotriol with more potent antitumor activities and lacking undesirable effects.

METHODSEighty derivatives of p-methyl-goniotriol have been synthesized in nine steps from alpha-D-glucoheptonic-delta-lactone (2). Compound 2 reacted with acetone in the catalyzer, H2SO4 and anhydrous MgSO4, and then reacted with 60% aqua HOAc, finally was oxidized by NaIO4 at room temperature into aldehyde 3 in a yield of 71.3%. The aldehyde 3 reacted immediately with P-CH3-PhMgBr giving mixture 4. The mixture 4 was oxidized by NaIO4, reacted with Ph3P = CHCO2Et and then induced by catalyzer. 1,8-Diazabicylclo[5, 4, 0]undec-7-ene in THF providing the compounds 6 and 7. The esterfication of 6 with cinnamyl chloride et al in 4-dimethylaminopyridine, Et3N gave the esters 8a-h. Acid hydrolysis of the acetone protecting group of 8a-h in 75% aqua HOAc gave compounds 9a-h. Their chemical structures were confirmed by IR, 1HNMR, MS and element analysis. The antitumor activities of the compounds were screened by MTT methods.

To investigate the effect of treadmill running on the ability of learning in young rats, male Sprague-Dawley rats (5 weeks of age) were used for the experiment. Animals were randomly divided into the control and running groups (n=15 in each group). The rats in running group were made run on a motor-driven treadmill for 1 week at a speed of 2 m/min for the first 5 min, at a speed of 5 m/min for the next 5 min, then at a speed of 8 m/min for the last 20 min. Then the Morris water maze was used to observe learning and memory ability of rats in both groups. The tests consisted of place navigation and spatial probe test. We found that, in place navigation training, the latency of rats in running group was less than that in control group (P<0.05); and from the third training session on, there was significant difference between the rats in control and running groups in swimming velocity (P<0.01); furthermore, it was observed that the rats in running group had stronger motivation and more exact orientation in searching for platform, which could be indicated by the index of turn angle and angular velocity. In spatial probe test, there was no significant difference between the two groups in swimming velocity, percentage of swimming distance and frequency of crossing platform in D quadrant, where the platform situated (P>0.05). These findings suggest that low speed treadmill running can enhance the ability of learning in young rats.
