Objective:To develop the Chinese version of the 22-item Impact of Event Scale-Revised (IES-R-C) and examine its reliability and validity. Methods:A sample of 439 female offenders experiencing at least one traumatic life event was tested. The authors examined the IES-R-C's retest reliability, internal consistency, discriminative validity and predictive value of the cut-off. Results:The test-retest reliability coefficient was 0.86;The Cronbach's coefficient of the IES-R-C was 0.96;The mean inter-item correlation coefficients ranged from0.42 to 0.60;The correlation coefficient of the three factors with the total scale scores ranged from0.84 to 0.91; The correlation coefficient among the three factors ranged from 0.75 to 0.89; Posttraumatic stress disorder (PTSD) and partial PTSD cases indicated significantly higher scores than non-PTSD cases. 34/35 in the IES-R-C total score seemed an appropriate cutoff indicative of high levels of sensitivity (0.86), specificity (0.86), and efficiency (0.86) in the broadly defined PTSD-positive groups (PTSD + partial PTSD). Conclusion: the of IES-R-C is a reliable and valid measure for assessing the posttraumatic stress symptoms in Chinese-speaking sample. The IES-R-C may be a useful self-rating diagnostic instrument particularly for survivors with PTSD symptoms as a clinical concern (PTSD + partial PTSD) by using a 34/35 cutoff in total score.

Objective To investigate the effect of intracoronary application of tirofiban on coronary slow flow patients with acute myocardial infarction during primary percutaneous coronary intervention (PPC1).Method It was a retrospective analysis of 187 patients with acute myocardial infarction treated with PPCI in the emergency department of Beijing Anzhen Hospital enrolled in this study from January,2008 through January,2011.The patients divided into 2 groups in terms of intra-coronary administration of tirofiban (tirofiban group) and intra-coronary use of nitroglycerol (control group).Data were statistically analyzed by using SPSS 13.0 software.Categorical variables were analyzed using x2 test and continuous variables were compared by t test.Results Between two groups,there were no differences in preoperative systolic pressure (P =0.245),the rate of TIMI flow 3 (P =0.568) after PPCI and ST segment resolution (P =0.824),LVEF (P =0.275) and in-hospital mortality (P =0.502).Compared with tirofiban group,the systolic pressure was lower and the rate of using intra-aortic counter-pulsation was higher in control group.Although the incidence of slight bleeding in the control group was lower than that in the tirofiban group,no severe bleeding was observed in both groups.Conclusions The effect of intracoronary use of tirofiban was similar to that of nitroglycerol in terms of improving slow flow of coronary artery.It could safely and effectively reduce the incidence of the coronary slow flow in the patients after PPCI,but it produced a little impact on systolic pressure.It may be a better method of choice for AMI patient with low blood pressure.

BACKGROUND:There are numerous studies on bone marrow mesenchymal stem cells(BMSCs)from small animals such as rats and rabbits,but no few reports addressing BMSCs from big animals.OBJECTIVE:To observe in vitro cultured goat BMSCs,and to understand its biological properties.METHODS:A healthy Chinese goat aged ten months was obtained to extract 5 mL fresh bone marrow from the posterior superior iliac spine by puncture following anesthesia.Using the whole bone marrow method,the samples were incubated in a sterile plastic culture flask and added with DMEM/F12 containing 10% fetal bovine serum.Following 80% 90% confluence,cells were digested by trypsin.Cells at passage 3 in logarithmic phase were collected and frozen,and then recovered.Changes in cell morphology were observed using an inverted microscope.Cell growth curve was measured using MTT assay.The potential of osteogenic differentiation was examined utilizing Von Kossa's staining.RESULTS AND CONCLUSION:The primary cultured BMSCs were cultured with adherent growth.The cells were spindle form.Cell morphology following passage 3 was similar,showing long spindle shape.Following freezing and recovery,cell adherence was slower compared with subculture cells,and no significant difference was detected in cell morphology and viability compared with subculture cells.Growth cycle was similar in passage 3-passage 5 cells.BMSCs entered lag phase at days 2 and 3,logarithmic phase at day 3,and platform phase at days 6 and 7,and then growth speed was slow.Goat BMSCs were positive for Von Kossa's stain at 3 weeks following osteogenic induction.Results verified that cultured goat BMSCs showed strong genetic stability and proliferation ability,and differentiated into osteoblasts.

Objective To prepare monoclonal antibody(McAb) against human tissue kallikrein (HK) and develop an ELISA kit allows for the in vitro quantitative determination of human tissue kallikrein in urine. Methods To generate a monoclonal antibody specific for TK, the synthetic TK peptide consisting of 12 amine acids(12P), was fused to keyhole limpet hemocyanin(KLH) and used for immunization. Using hybridoma screening, monoclonal secreting cell lines were identified and used to generate ascites in BALB/c mouse. Antibody was purified by affinity column chromatography. 12% SDS-PAGE and Western blot were used to visualize the purified antibody. This kit employs indirect competitive ELISA technique and BiotinAvidin System. 12P was fused to bovine serum albumin(BSA) and has been pre-coated onto a microplate at first. Standards and samples were added to the appropriate microplate wells with a biotin-conjugated McAb croplate well. A TMB substrate solution is added to each well. The enzyme-substrate reaction is terminating by the addition of a sulphuric acid solution and the color change is measured spectrotometrically at a wavelength of 450 nm. The concentration of tissue kallikrein in the samples is then determined by comparing the O.D. of the samples to the standard curve. Results 8 hybridoma cell lines secreting mAbs special to HK,SDS-PAGE and Western blot demonstrated successful preparing and purification of McAb( 100% ). The linearity of this ELISA kit is demonstrated(r =0. 990). The range of detection of the assay is 0.008 μg/ml to 0. 5 μg/ml. The assay remained stable, with no change in the values measured, over five cycles of freezing and thawing. Conclusion 8 McAbs against HK have been prepared successfully and possess high titer and specificity. The development of an ELISA kit for detecting HK can meet the needs of detection of HK in urine samples.
