05). Conclusion The maternal serum level of ADAM 12 in the first-trimester is a potential marker for aneupolyhaploid screening and early fetal loss prediction, and is suggested to be tested at 9-12 gestational weeks as part of prenatal screening.

Cell DNA content in heart, liver, kidney of rats were analysed by flow cytometer at different postmortem interved. The rsults show that mean cellular DNA content is 99.5% at 6 hours, 91.3% at 12 hours, 87.1% at 18 hours, 81.3% at 24 hours, 76.7% at 30 hours, 74.3% at 36 hours, 72.3% 48 hours as compared with that at o hours The results ingicates that the quantitative determination of cell DNA in the tissues, mentioned above may provide an objective and reliable approach for the estimation of postmortem time.

Objective:To identify the tannin-related constituents in the extracts of pomegranate peel by HPLC-ESI-MS. Methods:The separation was performed on a Kromasil C18 column (250 mm × 4. 6 mm,5 μm) with the mobile phase of water and acetonitrile. The flow rate was maintained at 1. 0 ml·min-1 and the detection wavelength was set at 256nm. The samples were analyzed in negative modes. Results:Five tannin-related constituents including gallic acid, punicalin,punicalagin,corilagin and ellagic acid were identified from the extracts of pomegranate peel. Conclusion:The new method is accurate and rapid. It can be used to identify the tannin-related constituents in pomegranate peel and provide new ideas for the research of active components in traditional Chinese medicine as well.

Objective A retrospective analysis were conducted to identify the effect of bypassing the emergency department on 30-days outcomes of patients with acute myocardial infarction undergone primary percutaneous coronary intervention ( PPCI) . Methods From June 2014 to April 2015, 187 patients underwent PPCI in Kunming General Hospital were included. 13 patients were excluded owing to their incomplete follow-up data. The total 174 patients were divided into two groups: the control group (n =59) who did not bypass the emergency department, and the bypass group ( n = 115) who bypassed the emergency department and directly received PPCI. The data of all patients were collected and analyzed. Results There were no significant differences in baseline characteristics and PPCI related data (including percentage of thrombus aspiration catheter used, length or diameter of stents applied between two groups (all P ﹥ 0. 05) . The bypass group had shorter door-to-ballon ( D2B) than the control group [ (67. 7 ± 21. 5) min vs. (89. 4 ± 23. 6) min, P ﹤ 0. 001] . There were no significant differences in 30-days all-cause mortality, re-myocardial infacrtion and target ressel revascularization (TVR) between the two groups (P ﹥ 0. 05) . Total MACEs rate in the bypass group was lower than in the control group (10. 2% vs. 1. 7% , P = 0. 012) . Logistic regression analysis showed that age, diabetes, pain-to-door (PTD) time and CK peak value were the main influencing factors for 30-day MACEs rate of patients receiving PPCI ( P ﹤0. 05) . Conclusions Bypassing the emergency department can shorten D2B time and reduce 30-days MACEs post-PPCI, but reducing the total ischemic time will be more beneficial to patients with acute myocardial infarction.

Objective To explore the manifestations of chest multi-slice spiral CT in patients with initial infection of swine-origin influenza A (H1N1) virus (S-OIV). Methods The chest multi-slices spirals CT images of 19 firstly diagnosed patients with swine-origin influenza A (H1N1) in our institution were retrospectively studied. CT manifestations were evaluated by three experienced radiologists. Location, appearance of lung abnormalities, abnormal distribution, pleural effusion and others (pericadiaum, lymphadenopathy and pleural thickening) were observed and quantitatively analyzed. The correlation of ground-glass and consolidation CT scores with the fever time was studied. Results The abnormal CT findings were observed bilaterally in 18 of 19 subjects including ground-glass (n= 3), consolidation (n=3 ), consolidation accompanied with ground-glass (n=12). Most of these lesions were distributed diffusively (n=14) while the others located in the middle and low lobes (n= 4). Unilateral (n=3) or bilateral (n=2) pleural effusion were observed. Lymphadenopathy (n=2), effusion of pericadium (n=1), pleural thickening (n=1) and cardiac enlargement (n=2) were also found in patients with H1N1. CT scores of ground-glass were 4. 25(n=2),3.75 (n=1),2.25(n=1),1.75(n=1),1.00(n=6),0.75(n=2), 0.50(n=2),0(n=4).CT scores of consolidation were4.25(n=1),4.00(n=1),3.75 (n=1), 2.75(n=1),1.25(n=3),1.00(n=2),0.75(n=2),0.50(n=1),0.25(n=3),0(n=4). CT scores of ground-glass were significantly correlated with the fever time (r= 0.776, P < 0.01), CT scores of consolidation had no correlation with the fever time(r=0.322,P > 0.01). Conclusions The most common CT findings in patients with S-OIV infection are diffuse distribution of bilateral ground-glass opacities with or without associated focal or multifocal areas of consolidation. The increasing of ground-glass's range could be the marker of progression of H1N1 pulmonary infection at initial stage.
