Chinese Journal of Clinical Laboratory Science 2006;0(03):-
Objective To identity bacteria of bacteroides group by PCR.Method The universal primers were designed according to the sequence of 16S rRNA,then 13 strains bacteroides and the other non-bacteroides were amplified by PCR. PCR products were then sequenced and analyzed by Blast.Results Thirteen strains of bacteroides were amplified, and the non-bacteroides were not amplified. The pairs of primers had highly specificity.Comparing the gene sequences of the 13 strains,bacteroides with corresponding standard 16S rRNA sequences,the homology was from 81% to 100%.Conclusion The established PCR assay could specially amplify bacteroides and had good sensitivity with 100 genomes/ml.

Objective:To search for common epitopes of(H5N1) from different areas in the world in order to develope epitope-bacterin by the way of immunoinformatics.Methods:Firstly,homologous degree of the amino acid sequence of VIA from different areas was compared on the basis of the database in Genebank with soft-ware ClustalW1.83.The common epitopes which were able to bind strongly to MHCⅠ molecule were selected.Results:Though homologous degree of amino acid sequence of VIA from different areas was not completely similar,there were some common epitopes among these strains analyzed.The common epitopes were shown to bind strongly with MHCⅠ molecule.Conclusion:These common epitopes may be used to develope epitope-bacterin for preventing infection of AIV(H5N1).

Objective To investigate the diagnostic value of barium stury of small bowel obstruction due to various bowel diseases.Methods Barium meal study and enteroclysis (small bowel enema)were performed in 23 patients with incomplete small bowel obstruction due to small bowel diseases confirmed by operation.The imaging data were retrospectively analysed.Results Of the 23 patients,14 cases were malignancy,9 cases were benignant.Conclusion Both barium meal study and enteroclysis( small bowel enema) with air-barium double-contrast technique are of diagnostic value in incomplete small bowel obstruction due to small bowel diseases.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

Objective To analyze the massive explosions and burn at Tianjin Port in 2015 resulted in a mass casualty event,and the entire course of response of a hospital to deal with such major sudden accident in order to find a rational strategy for optimal use of medical resources and reduce the critical mortality.Methods This study was done by a retrospective analysis of data from one trauma center at an academic hospital.Data including outcome,triage,severity and pattern of injuries,patient flow,and medical resources used were obtained by the review of hospital records.Results This disaster caused 165 deaths,8 missing contact,and 797 non-fatal casualties.The Pingjin Hospital admitted 298 casualties,and 29 of them were seriously injured referred to by Tianjin Emergency Medical Center.Excessive triage rate made after transfer to another hospital was 62.07% with 11 of the 29 severely injured patients.Maximum (also the first)surge had 147 injured patients arrived around one hour after incident,the second surge had 31 seriously injured patients occurred around 4 hours after incident.Of them,17 patients needed surgery and 17 patients were admitted to the intensive care unit.Conclusions These data showed that the number of casualties in the first surge was substantially larger than predicted and those casualties had less severe trauma,whereas the number of the injured in the second surge was less but the trauma was more severe.In order to maintain the hospital surge capacity,an effective re-triage and a hospital-wide damage control principle can be used to deal with.
