Objective The changes of cytokine expression on a genomic scale in CD4 + cell of mice c hronically infected with Schistosoma japonicum and their roles in the pathog enesis of schistosomiasis were studied. Methods CD4 + cells were isolated from sp le ens of mice 13 wk infected with Schistosoma japonicum. We used the cDNA micr oarr ay technique to explore the cytokine gene expression profile of CD4 + cells f ro m normal and chronic infected mice. Three-color flow cytometry was performed to study intracellular protein levels of IFN-?、IL-4 of CD4 + cell. Results In the CD4 + cell of chronically infected mice, IL-4 was remarkably increase d at both transcription and protein expression levels (P

Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.

In order to establish the optimum condition for purifica tion of the nucleoprotein(NP) of rabies virus by immunoaffinity chromatography, the efficient and non-denaturative eluents(Mg-el) was obtained by using ELISA elution model; furthermore, it didn't damage the activity of NP. Two kind of NPs , expressed by recombinant vaccinia virus (rVac-N) and recombinant baculovirus (BRN), were purified by a Sepharose CL 4B column and a 2C12- Sepharose 4B colum n. By Western-blot and SDS-PAGE, high purity and good antigenical intact NPs w ere identified. The purified ribonucleoprotein (RNP) of rabies virus 5aG strain was also obtained. After immunized with NP and RNP, mice developed a strong anti -nucleoprotein response and were protected against a lethal challenge of rabies virus CVS strain. There were not difference been observed among the mice immuni zed with different purified protein. These data indicate that the NPs are antige nical and immunogenical comparable to the authentic rabies RNP and therefore pre sent a potential source of an effective ,safe and economical subunit vaccine.

Objective To learn the relationship and operating mechanism between medical staff's loyalty and patient satisfaction.Methods Medical staff and inpatients of a tertiary hospital in Nanjing were sampled at a 1:2 ratio for study,with 840 questionnaires released and 269 valid questionnaires recovered;medical staff service quality as perceived by inpatients served as the intermediate variable,with Mplus7.0 used to build a structural formula model for an empirical study of the relationship between staff loyalty and patient satisfaction.Results Staff loyalty exerts certain positive influence on patient satisfaction and staff service quality ( P < 0.001 ); service quality also exerts some positive influence on patient satisfaction (P<0.001);staff loyalty indirectly exerts positive influence(P<0.001)via the service quality as perceived by patients(mediation effect value 0.364 > direct effect value 0.143).Conclusions Structural formula model can reveal the relationship and extent of the influence of staff loyalty on patient satisfaction.This indicates that hospitals should enhance the loyalty,medical competence and communication skills of their medical staff for higher patient satisfaction.

Objective To compare the effects of UVA irradiation on cell morphology,quantity and expression of inducible nitric oxide synthase (iNOS) mRNA and protein in human fibroblasts versus a kerati- nocyte cell line HaCaT.Methods Human fibroblasts and HaCaT cells were cultured and irradiated by 5 J/cm~2 UVA.Then,at 24,48 and 72 h after the stimulation,the cell morphology was observed under an in- verted microscope,and iNOS mRNA and protein were measured by RT-PCR and immunohistochemistry method,respectively.Results After the irradiation,human fibroblasts showed shrinkage at the three time points,the quantities of the cells began to decrease significantly at 24 h (P
