Objective To construct a lentiviral vector of RNA interference (RNAi) of murine triggering receptor expressed on myeloid cells-1 (TREM-1) gene and to explore the effect of TREM-1 on the inflammatory response caused by Bacteroides fragilis. Methods Four target sequences were selected according to murine TREM-1 mRNA sequence, and then 4 pairs of double-strand DNA oligo according to these target sequences and one pair of negative control double-strand DNA oligo were designed and synthesized. These fragments were subcloned into pGCSIL-GFP/Lenti plasmid. After being identified by PCR and sequencing, these plasmids were cotransfected into 293T cells to package lentiviral particles. The lentiviral vector particles were transfected into Raw 264. 7 cells and TREM-1 expression in the transfected cells was assayed by real-time PCR and ELISA. Different concentrations of Bacteroides fragilis lipopolysaccaride (LPS) were administered in the Raw264. 7 cells, and the cells were stimulated with LPS for 12 h. TREM-1 expression was determined by real-time PCR and ELISA at the time points. Results PCR and sequencing confirmed that lentiviral vectors had the correct structure and could express high titer of virus. After being transfected into Raw264. 7 cells, TREM-1 expression was knocked down significantly by all of these lentiviral vectors at both protein and mRNA levels, and the pGCSIL-GFP/Lenti-1 had the most efficient interference. TREM-1 was upregulated in the presence of Bacteroides fragilis LPS, and this increase was partly abrogated in the TREM-1 siRNA-treated cell models of endotoxemia, depending on the sequence. Conclusion The lentivirus RNAi vector of TREM-1 was constructed successfully. The lentivirus RNAi vector of TREM-1 can inhibit the expression of TREM-1 in the murine endotoxemia model caused by Bacteroides fragilis LPS.

OBJECTIVE To ascertain the causes of unreported hospital infection in our hospital and apply countermeasures. METHODS To adopt investigation way to review and analyze 34 694 hospital files in our hospital from Aug 2002 to Jul 2004. RESULTS From them 1164 cases had experienced hospital infection,264 were unreported,the monthly unreported rate decreased from 52.50% to 0;the yearly unreported rate decreased from 36.17% to 10.67%. CONCLUSIONS The unreported reason is because the relevant staff lack infection knowledge,the control and supporting system isn′t so efficient.So the key to reduce the missing report rate is to enhance the awareness of the hospital infection control among the staff in hospital,to strengthen communication and cooperation,and to implement the administrative regulation.

Objective To study the effect of Jade -Screen Powder (JSP)on regulating expression of 5 microRNAs associated with helper T cells in asthmatic mouse model.Methods Forty Balb /c mice were randomly di-vided into 4 groups,1 0 mice for each group,namely normal control,asthma model,JSP treatment and Dexamethasone treatment.The mouse models of allergic inflammation on both upper and lower airways were established by ovalbumin sensitization and challenge.Interleukin(IL)-1 3 and IL -1 7 expressions were detected from lung homogenates by ELISA.Hematoxylin and eosin staining was also performed to observe the pathological changes in the lung tissue.The expressions of miR -1 46a,miR -1 46b,miR -21 0,miR -1 26 and miR -21 a were detected by quantitative real time PCR from splenocytes.Results The lower levels of IL -1 3 [(6.382 ±1 .690)μg/L]and IL -1 7 [(24.21 2 ± 1 .250)μg/L]were found in JSP treatment group compared with those in the asthma model group [(20.1 54 ±7.960)μg/L;(50.31 2 ±5.770)μg/L,rseparately],there was significant difference in IL -1 3 between JSP group and the asthma model group,as well as IL -1 7 (t =3.785,P =0.005;t =9.891 ,P =0.000).Same findings were found in Dexamethasone treated group as well [IL -1 3:(9.366 ±3.460)μg/L,IL -1 7:(29.1 32 ±4.960)μg/L;t =2.779, P =0.024;t =6.225,P =0.000].However,upregulation of miR -21 0 was observed in JSP treatment group (2.052 ± 0.871 )compared with that in the asthma model group (4.034 ±1 .379)(3.95 folds,t =2.71 8,P =0.026).Mean-time,the expression of miR -1 26 in JSP group (4.920 ±0.924)and Dexamethasone group (3.862 ±1 .51 0)in-creased compared with asthma model group (6.024 ±0.447)(2.1 5 folds,t =2.405,P =0.043,and 4.48 folds,t =-3.069,P =0.01 5).Conclusions Th2 and Th1 7 T cells participate in the pathogenesis of asthma and the asthmatic process can be inhibited by JSP.JSP may affect the helper T cells by regulating miR -21 0 and miR -1 26.
