Preeclampsia is a leading cause of maternal and infant morbidity and mortality. It is very important to explore the biomarkers for the early prediction of preeclampsia. Some peptides released from placenta, such as soluble Flt-1 and placenta growth factor (PlGF), have been revealed for definite prospects of application. Meanwhile, the recent advances in proteomics, metabolomics and microRNA shed light on searching of new biomarkers for preeclampsia prediction.

Objective To evaluate CT and MRI features of brain lesions in CO poisoning and to compare the ability of detecting rate of lesions by CT and MRI.Methods CT and MRI appearances in 52 cases with CO poisoning were analysed and compared.Results Necroses and degenerations of globus pallidus in 9 cases,cerebral white matter demyelination in 3 cases and brain atrophy in 3 cases were showed by CT.The detecting rate was 28.8% by CT while,necroses and degeneration of glodus pallidus were observed in 24 cases and white matter change in 7 cases were observed by MRI,the detecting rate was 59.6% which was higher than that of CT (?

This article summarizes the bleaching of pulp by white-rot fungus, including the type of white-rot fungus, the type of pulp, the equipment used to bleach by white-rot fungus, and some problems and prospect in practical application by white-rot fungus.

To explore the new method of discriminating Cistanche deserticola, Cynomorium songaricum and Orobanche pycnostachya by using PCR amplification of specific alleles. 30 samples of the different C. deserticola, 21 samples of C. songaricum and O. pycnostachya were collected. The total DNA of the samples were extracted, the ITS sequences from C. deserticola, C. songaricum and O. pycnostachya were amplified by PCR and sequenced unidirectionally. These sequences were aligned by using ClustulW. Specific primer was designed according to the ITS sequences of specific alleles, and PCR reaction system was optimized. Additionally, compare with the identification of specific PCR method and DNA sequence analysis method. The result showed that the 331 bp identification band for C. deserticola and the adulterants not amplified bands by a single PCR reaction, which showed good identification ability to the three species. PCR amplification of specific alleles can be used to identify C. deserticola, C. songaricum and O. pycnostachya successfully.

Objective To determine the association between atrial fibrillation(AF)and coronary artery disease(CAD)in elderly patients.Methods Based on autopsy data from 1990 to 2005,69 male patients with over 70 years old and AF history(32 with chronic AF,37 with paroxysmal AF)and diagnosed as CAD clinically were selected as AF group.Other 60 age-matched male patients without AF history were selected as the control group.The pathological changes of the coronary arteries between the groups were compared.Results The morbidity of CAD and myocardial infarction were 55.1% and 42.0% in AF group and 53.3% and 35% in the control(P＞0.05).The pathological changes of the coronary arteries between the two groups were similar(P＞0.05).The AF group had a heavier heart weight[(440.5?81.9)g vs(398.7?82.2)g,P＜0.01]and a thicker left ventricle [(1.42?0.34)cm vs(1.27?0.32)cm,P＜0.05]than did the control.The paroxysmal AF group had more branches of arteries(17 vs 5,P＜0.05)with pathological lesionⅣthan did the control. Conclusions There is a high morbidity of CAD in elderly patients,but it is not in relation to the occurrence of AF.

Although quality assessment is gaining increasing attention,there is still no consensus on how to define and grade postoperative complications.The absence of a defimition and a widely accepted ranking system to classify surgical complications has hampered proper interpretation of the surgical outcome.This study aimed to define and search the simple and reproducible classification of complications following hepatectomy based on two therapy-oriented severity grading system:Clavien-Dindo classification of surgical complications and Accordion severity grading of postoperative complications.Two classifications were tested in a cohort of 2008 patients who underwent elective liver surgery at our institution between January 1986 and December 2005.Univariate and multivariate analyses were performed to link respective complications with perioperative parameters,length of hospital stay and the quality of life.A total of 1716 (85.46％) patients did not develop any complication,while 292 (14.54％)patients had at least one complication.According to Clavien-Dindo classification of surgical complications system,grade Ⅰ complications occurred in 150 patients (7.47％),grade Ⅱ in 47 patients (2.34％),grade Ⅲa in 59 patients (2.94％),grade Ⅲb in 13 patients (0.65％),grade Ⅳa in 7 patients (0.35％),grade Ⅳb in 1 patient (0.05％),and grade Ⅴ in 15 patients (0.75％).According to Accordion severity grading of postoperative complications system,mild complications occurred in 160 patients (7.97％),moderate complications in 48 patients (2.39％),severe complications (invasive procedure/no general anesthesia) in 48 patients (2.39％),severe complications (invasive procedure under general anesthesia or single organ system failure) in 20 patients (1.00％),severe complications (organ system failure and invasive procedure under general anesthesia or multisystem organ failure) in 1 patient (0.05％),and mortality was 0.75％ (n=15).Complication severity of Clavien-Dindo system and Accordion system were all correlated with the length of hospital stay,the number of hepatic segments resected,the blood transfusion and the Hospital Anxiety and Depression Scale-Anxiety (HADS-A).The Clavien-Dindo classification system and Accordion classification system are the simple ways of reporting all complications following the liver surgery.

Objective:To study whether the orientation behavior of rats is affected by multi-sensory information.Methods: SD rats were randomly divided into 2 groups:the audio-visual integration group and pure audio group.The orientation behaviors of rats were observed after given single modal and multi-modal sensory cues with spatial disparities.Results:We found that when the temporal and spatial audio cues were coincident to a target visual cue,the rats had a markedly reduced reaction time and increased success rate in orientation behaviors;there was an obvious audio-visual integration effect.The integration effect was more obvious when the intensity of target visual cue was weak,with the enhancement efficiency being(87.3?8.5)%, significantly higher than that when the intensity of target visual cue was stronger(27.6%,P
