OBJECTIVE To observe the curative effect of continuous lumbar cisterna drainage for severe intracranial infection. METHODS We cured 24 patients of severe intracranial infection with the method of continuous lumbar cisterna drainage and injecting sensitive antibiotics to subarachnoid space. RESULTS Making use of continuous lumbar cisterna drainage and injecting sensitive antibiotics to subarachnoid space turned to be an effective method for severe intracranial infection,all patients had been cured. CONCLUSIONS In patients of severe intracranial infection,the responsible agents have been transformed,we conclude that it improves the outcome obviously to drain the CSF and inject sensitive antibiotics to subarachnoid space.

Objective To analyze changes of DNA demethylation analysis of FOXP3 TSDR at the beginning of the secondary pulmonary tuberculosis patientsby utilizing real-time PCR technology.Methods To select 47 patients of secondary pulmona-ry tuberculosis as a research group from June 2014 to May 2015 and 40 healthy donors as a control group.The peripheral blood mononuclear cells (PBMC)of research group and control group were isolated.CD4+CD25+T cells were isolated from PBMC.Genomic DNA was isolated from CD4+CD25+T cells.PCR was performed in a final reaction volume containing dem-ethylation-specific primers.Plasmid standard was generated by PCR products were enzyme digestion,TOPO TA cloning,and recycling and purification.A real-time PCR system was established by quantitatively analyzing the specificity of FOXP3 TS-DR demethylation to treg (regulatory T-cell).Treg numbers of control group at week 0 and research group treated at week 0,week 2,week 4 and week 8 by using real-time PCR assay of the FOXP3 TSDR demethylation.The experimental data was analyzed by using SPSS 1 6.0 software.Results The M.tuberculosis in sputum of research group were positive by smear mi-croscopy,however the results of control group were negative.The treg frequency of control group,2+ group and 3+ group respectively was 1.63%±0.70%,1.96%±0.10% and 0.86%±0.21%,respectively.The difference between the treg fre-quency of control group and that of 2+ group by smear microscopy had not statistical significance,however which of 3+group was opposite.The average treg frequency of research group treated at week 0,2,4 and 8 respectively was at 1.05%, 2.04%,3.44% and 2.79%,range of which respectively was 0.32%~2.03%,0.95%~3.95%,2.35%~4.95% and 1.02%~4.27%,95% confidence interval of which respectively was (0.93%,1.18%),(1.85%,2.24%),(3.27%,3.61%) and (2.60%,2.98%).The treg frequency of difference between control group and research group at week 0 had statistical significance (t=4.669,P<0.05).The treg frequency was influenced by time of therapy,using One-Way ANOVA analysis (F=347.2,P<0.001,df=3,within-subjects Contrasts:F=407.4,P<0.001,df=3).Test of the treatment time and group interaction effect was linear (F=678.2,P<0.001,df=1).Conclusion DNA demethylation analysis of FOXP3 TSDR was high sensitivity and specificity in monitoring changes of treg at the beginning of the secondary pulmonary tuberculosis pa-tients.
