Chinese Journal of Medical Library and Information Science 2014;(1):52-55
Proposed in this paper is to compile The synopsis for the general list of medical documents in minority nationalitiesand to make the scientific classification and systematic organization of medical documents in minority nationalities, thus breaking their time and space limitation and laying the foundation for the establishment of medi-cal literature resources support system, according to their scattered collection, severe damage, abstruse written lan-guages, and the fact that most of them are unorganized or catalogued, which significantly hinder their development and utilization.

Objective:To investigate the antitumor efficiency of the special cytotoxic T lymphocytes(CTLs) activated by dendritic cells(DCs) pulsed with K-ras (12-Val) antigen.Methods:DCs was generated from PBMC in the presence of granuloceyte/macrophage-colony stimulating factor(GM-CSF),interleukin-4(IL-4)in vitro.DCs were differently sensitized with K-ras mutant pancreatic cancer cell line,K-ras(12-Val) mutant peptide,K-ras(12-Val) mutant peptide with the surface of cationic nanoparticle.Cell surface markers on DCs was measured by flow cytometry.The activation of CTL induced by DCs was detected by ~3H- thymidine incorporation test.The killing effects of CTL to pancreatic cancer was detected by ~(125)I-UdR release test. Production of IL-12 and IFN-γ by DCs and PBMC was detected by ELISA.Results:Compared with DCs pulsed with K-ras(12-Val) mutant peptide and K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle,DCs pulsed with whole tumor antigen could better induce CTLs killing activity(P<0.05).The DCs with K-ras(12-Val) mutant peptide and K-ras mutant peptide with the surface of cationic nanoparticle could produce specific CTL killing activity aganist pancreatic cancer cell line Patu8988(K-ras+)(P<0.05),but not SW1990(K-ras-)(P>0.05). K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle at lower concentrations can be effectively presenting on the surface of DCs than only K-ras (12-Val) mutant peptide.Conclusion:K-ras (12-Val) mutant peptide with cationic carrier can be effectively presenting and expression of DCs and induce CTL specific killing activity aganist pancreatic cancer cell lines with K-ras (12-Val) mutant peptide.

Objective To investigate the relationships between the level of heat shock protein (HSPs) 70 and severity of sepsis in order to find its effects on the status of sepsis and the prognosis of the patients. Methods In total, 120 patients diagnosed to be suffering from sepsis from the emergency department were selected as studying subjects. According to SAPS Ⅱ score, all of these patients were divided into mild, moderate and severe groups (n =40 in each group) , and at the same time, 40 healthy volunteers were studied as controls. The levels of intracellular HSPs70 in peripheral blood neutrophil cells in the mild, moderate and severe groups were determined by using flow cytometry, while serum levels of procalcitonin (PCT) and C-reactive protein ( CRP) were measured as well. Results ① The levels of heat shock proteins HSPs70 in neutrophil cells and PCT in patients with sepsis escalated gradually with the increase in SAPS Ⅱ score, and there were significant different among the mild, moderate, and severe sepsis groups(P<0.05). ② In all septic patients, the death happened only in the severe group. Compared other markers in the survivals , the level of heat shock protein HSPs70 was significantly higher in fatal patients. ③ In curve plot analysis in the patients with sepsis done by the curve of receiver operating characteristic (ROC) , the area of HSPs70 in neutrophil cells under the curve was significantly larger as compared with that of PCT and CRP. Conclusions Heat shock protein HSPs70 has a certain clinical value in determining the severity of disease and prognosis of patients suffering from sepsis.
