A rapid and sensitive method has been developed for the simultaneous determination of four selenium species Se(Ⅵ), Se(Ⅵ), selenomethionine, and Se-methylselenocysteine in Se-enriched yeast by liquid chromatography-hydride generation atomic fluorescence spectrometry (HPLC-HG-AFS). The isolation of the analytes from yeast samples was accomplished by proteaseⅩⅣ and trypsin enzymatic digestion. The target compounds were separated on a PRP-X100 anion exchange column and analyzed by HG-AFS. The mobile phase was 20 mmol/L (NH4)2HPO4. Good linearity was obtained for all the selenium species, with linear correlation coefficients higher than 0. 9996. The LODs of the four species were between 0. 5 and 5. 0 μg/kg. Average recoveries for the four analytes were in the ranges of 82 . 5%-101 . 2%, with intra-and inter-day RSD lower than 8. 6% and 14. 5, respectively. The proposed analytical method is simple, sensitive, with low operation cost, making it applicable for the determination of the selenium species in Se-enriched feeds.

Objective To preliminarily evaluate the value of color power doppler ultrasonography in the diagnosis of sacroiliitis in ankylosing spondylitis(AS). Methods Fifty-seven sacroiliac joints in 31 patients with active AS and 40 sacroiliac joints in 20 volunteers were detected by color power doppler ultrasonography.The color flow signs inside the sacroiliac joints were observed,and the resistance index(RI) was measured. Results In active AS,color flow signs were seen in 55 joints,and the mean RI value was 0.53?0.08 in 45 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography.In the volunteers,color flow signs were seen in 16 joints,and the mean RI value was 0.97?0.01 in 6 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography. Conclusion The abnormal flow signs at the sacroiliac joints can be detected by color power doppler ultrasonography.Low RI values provide diagnosis evidence for active AS.

Objetctive To summarize the associated complications with circulatory support device,and provide reference for chnical practice.Method A total of 8306 consecutive patients who underwent open heart surgery,in Department of Post-operation Intensive Care Unit of the Cardiac Surgery,Anzhen Hospital,Capital Medical University,was retrospectively studied from January 2005 to February 2007.And the clinical data of 246 patients including 63 female and 183 male patients with mean age 56.7±14.2 years supported with various circulatory support devices for perioperative cardiorespiratory function failure in ICU were analyzed.Left ventricular assist device (LVAD) was used in 3 patients by the cannulation of the left alritan and ascending aorta.The extracorporeal membrane oxygenation(ECMO) was established in 48 patients for postoperative cardiorespiratory function failure.The vencarterial bypass was established by cannulation of the right atrium in 41 patients and femoral artery and of venovenons in 2 patients,and of the right atrium and ascending aorta in 5 cases,lntra-aortic balloon pumping(I-ABP)was performed via the femoral artery either percutaneonsly by the Seldinger technique in 195 patients.The cardiac operations included coronary artery bypass grafting (n=170),coronary artery bypass grafting with romoldingof left ventricle (n = 22),coronary artery bypass grafting with valvular operation (n=10),valvular operation (n=27),heart transplantation(n=8),correction of congenital heart defects(n=6),aortic operations(n=2).The duration of circulatory support ranged from 4 to 451 hours.Correlative complications of 3 kinds of circulatory support device were compared and repair of ventricular septal perforation in the wake of acute myocardial infarction (n=1).Results Seventy-eight (31.7%) patients died.Seventy-one(28.9% ) patients devdoped various complications including infection(n=27),renal failure required renal rephcement therapy (n=27),re-exploration for bleeding(n=24),haemolysis(n=6),limb ischemia(n=15),neurological complications(n=6),oxygenator failure(n=7) Conchusions The improvement of management to reduce complications may result in improved outcomes of patients supported with circulatory support devices.

Recently traditional Chinese medicine (TCM)-induced liver injury has been an unresolved critical issue which impacts TCM clinical safety. The premise and key step to reduce or avoid drug-induced liver injury (DILI) is to identify the drug source of liver injury in early stage. Then the timely withdrawal of drug and treatment can be done. However, the current diagnosis of DILI is primarily governed by exclusive method relying on administering history supplied by patients and experience judgment from doctors, which lacks objective and reliable diagnostic indices. It is obvious that diagnosis of TCM-induced liver injury is especially difficult due to the complicated composition of TCM medication, as well the frequent combination of Chinese and Western drugs in clinic. In this paper, we proposed construction of research pattern and method for objective identification of TCM-related DILI based on translational toxicology, which utilizes clinical specimen to find specific biomarkers and characteristic blood-entering constituents, as well the clinical biochemistry and liver biopsy. With integration of diagnosis marker database, bibliographic database, medical record database and clinical specimen database, an integrative diagnosis database for TCM-related DILI can be established, which would make a transformation of clinical identification pattern for TCM-induced liver injury from subjective and exclusive to objective and index-supporting mode. This would be helpful to improve rational uses of TCM and promote sustainable development of TCM industry.

Objective:To investigate the clinical efficacy of fluorescence in situ hybridization(FISH)in prenatal diagnosis of chromosomal aneuploidy.Methods:FISH and karyotyping analysis were done in 120 samples of amniotic fluid from pregnant women.Results:FISH analysis results were consistent with those of karyotyping,the dectecting rate can reach 100%for chromosomal aneuploidies.There was no significant difference in the preference for FISH or karyotying for prenatal diagnosis when facing high matemal age,multi-indications and other factors(P>0.05).FISH was better when biochemical datafor down's syndrome were positive (P=0.029),however karyotyping was better when there was abnormal fetal ultrasound scan(P=0.000).Conclusions:FISH can detect the chromosomal aneuploidy quickly and accurately,especially when biochemical data for down's syndrome were positive.FISH could be the first choice for prenatal diagnosis in the third trimester of high-risk pregnancy.

Objective To investigate BAALC(brain and acute leukemia cytoplasmic)gene expression in patients with de novo acute myeloid leukemia(AML)and its clinical significance. Methods BAALC expression was determined by real-time quantitative polymerase chain reaction(RQ-PCR) in 63 de novo AML patients.The association between BAALC expression and therapeutic effect was analyzed.Results The correlation coefficiencies were over 0.99 for standard curves of RQ-PCR method. BAALC expression was detected in 49(78%)AML patients.The peripheral WBC counts,hemoglobin, platelet counts and the bone mahow blast cell percentage at onset in 31 AML patients with high BAALC expression were(26.3?18.1)?10~9/L,(78.3?21.8)g/L,(76.9?64.5)?10~9/L and(61.2?22.3)% and those of 32 AML patients with low BAALC expression were(30.2?21.7)?10~9/L,(81.6?30.9)g/L, (73.9?57.2)?10~9/L,(54.3?16.3)%,respectively.No statistic differences were found between these two groups.The AML patients with normal chromosome karyotypes are more likely to have a high BAALC expression(68%)compared with those with abnormal chromosome karyotypes(23%,?~2=12.093,P= 0.001).AML patients with normal cytogenetics and high BAALC expression shows significant lower CR rate (65%)compared with those with low BAALC expression(84%,?~2=6.573,P=0.013). Conclusion High BAALC expression may define an important risk factor in AML with normal cytogenetics and predicts an adverse prognosis.
