Nanocrystal N-Zn-Ag/TiO2 powders were prepared with N-Zn/TiO2 by photo deposition method. A series of pure polymers P3HT[poly（3-hexylthiophene）], P3OT[poly（3-octylthiophene）], P3DT[poly（3-decylthiophene）] and P3DDT[poly（3-dodecylthiophene）], was synthesized, which were used to synthesize p-n type semiconductor mate- rials P3HT/N-Zn-Ag-TiO2, P3OT/N-Zn-Ag-TiO2, P3DT/N-Zn-Ag-TiO2 and P3DDT/N-Zn-Ag-TiO2 by in situ che- mical method. X-Ray diffraction（XRD） and infrared（IR） spectroscopy showed the structure of the polymers and complexes. Ultraviolet-visible（UV-Vis） spectra and cyclic voltammograms（CV） showed the optical and electronic performance of the polymers and complexes. Two new single and double organic thin film heterojunction solar cells were prepared with the above mentioned synthesized powders as raw materials. Current-voltage（I-V） measurements indicate that the conversion efficiency of the single organic thin film heterojunction solar cell is higher than that of the double organic thin film heterojunction solar cells. Single organic thin film heterojunction solar cells based on P3DT/N-Zn-Ag-TiO2 can get a photoelectric conversion efficiency of 0.0408%. The performance of electronic trans- form between electron donor and acceptor on organic thin film solar cells was researched.

To study the transcriptional regulation of urokinase receptor (uPAR) in high- (95D) and low-metastatic (95C) human lung cancer cells, we performed PCR to amplify 2238 bp uPAR promoter from 95C and 95D cells. According to the results of sequencing, five different bases are found in uPAR promoter between 95C and 95D cells. The results of luciferase activity assay showed that these differences have no significant effect on the uPAR promoter activity. Based on a normal uPAR promoter, progressive truncated mutants were constructed. The transient transfection/reporter assay showed that the promoter region from –136 to +9 may interact with relevant nuclear factors, which result in different levels of uPAR expression between 95C and 95D cells.

Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances. Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006. Study selection Relevant articles on studies of cardiac troponin were selected. Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high （about 5 times above normal）. On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted. Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the ＂golden cardiac marker＂ of this time.
