The value of combined application of both ECG-gated cine MRA and 3D-CEMRA in the detection of large intracranial aneurysms was evaluated and the findings were compared with those of conventional MRA and DSA. Twenty-four patients with 26 large intracranial aneurysms underwent MRI and DSA. All these aneurysms, diameter from 15 to 39 mm, were located at internal cerebral artery (n=12), vertebral artery (n=3), basilar artery (n=4), anterior cerebral artery (n=2), middle cerebral artery (n=2), anterior communicate artery (n=2) and posterior communicate artery (n=1). Thirteen cases of hematoma or cavernoma were studied as control group. All patients were examined on GE 1.5T MR system. ECG-gated cine MRA was performed with 2D multi-phase fast gradient-recalled echo sequence in a single section. All the images were analyzed with signal intensity VS time curve for differentiating intraaneurysmal blood flow from static tissue. The results were analyzed by statistic "t" test. 3D-CEMRA was performed with spoiled gradient-recalled echo and one dose of Gd-DTPA. All data was processed with multi-plannar reformat (MPR) and tomography for the demonstration of aneurysms in detail. All 26 aneurysms were demonstrated successfully by combined application of both cine MRA and 3D-CEMRA. Compared to DSA and conventional 3D-MOTSA, its sensitivity and specificity figures were both 100%. Cine MRA could differentiate the blood flow from the static tissue. The intensity VS time curves of intraaneurysmal blood flow offered fluctuating form and average signal change between systole and diastole period was about 89.8 +/- 37.4; However, under the control group, intraaneurysmal thrombus or cerebral hemorrhage or cavernomas had no significant signal change and the curves offered steady form with the average signal change being about 8.2 +/- 6.3. There was statistically significant difference between the intraaneurysmal blood flow and static tissue (P=0.025, <0.05). 3D-CEMRA was very useful in demonstrating the aneurysmal size, intraaneurysmal thrombus formation, neck and the detailed relationship of the aneurysm to the surrounding structures. It was concluded that the combined application of both cine MRA and 3D-CEMRA might be a valuable clinical tool for the detection of large intracranial aneurysms.

Objective To explore the changs of serum brain type creatine kinase isoenzyme(CK-BB),cystatin C of newborns with hypoxic-ischemic encephalopathy(HIE) and assess their applications.Methods The serum concentrations of CK-BB and cystatin C were measured by turbidimertric immunoassay in 56 HIE newborns and 42 normal neonates.Results 1.Compared with controls,the concentration of serum CK-BB in moderate HIE newborns had significant differences(P

A persistent infection model was established after human hepatoma cells infected by Japanese encephalitis viruses were subcultured for several times. Viral titers of mutant viruses in persistently infected cells were examined by plaque methods using BHK cells. Nucleotides of the E coding region of two wild and two mutant viruses were amplified by RT-PCR. PCR products were sequenced by ABI-PRSM 310 sequencing system. Compared to JaGAr-01 wild strains, four amino acids were replaced (E61Tyr --> Asp, E219His --> Tyr, E384Val --> Glu, E418Pro --> Ala) in the E sequence of JaGAr-01 persistently-infected mutant strains. Eleven amino acid replacement (E51Arg --> Ser, E61Tyr --> Asp, E83Lys --> Glu, E123Ser --> Arg, E209Arg --> Lys, E227Pro --> Ser, E276Asp --> Ser, E290Arg --> Lys, E387Lys --> Arg, E418Leu --> Pro, E454Arg --> Gly) was also noted when we compared the E sequence between persistently infected Nakayama and its wild strains. A lot of similarities of amino acid sequence between mutant strains JaGAr-01 and Nakayama were also noted. It was concluded that geno-variation existed in E region of mutant viruses and the mutant protein encoded by E region, especially the mutation of E61 (Tyr --> Asp) may contribute to the maintenance of the persistent infection of Japanese encephalitis virus.

Furthermore, the research and progress on protein engineering of feed phytase was reviewed, including phytase over-expression, phytase thermostability, catalytic efficiency and optimum pH.

Objective:To establish a glioma cell line U251 stably expressing programmed cell death 4(PDCD4)gene,and to observe the influence of exogenous PDCD4 gene on the proliferation and cell cycle of U251 cells.Methods:Recombinant eukaryotic expression vector pEGFP-PDCD4 was transfected into human glioma cell line U251 by Lipofectamine 2000,and the U251 cells stably expressing PDCD4 were established by G418 selection.Reverse transcription polymerase chain reaction(RT-PCR)and Western blotting were employed to detect the expression of PDCD4 mRNA and protein.Furthermore,cell proliferation and colony forming ability were determined by cell counting and colony formation assay;the cell cycle was detected by FACS.Results:High expression of PDCD4 mRNA and protein was observed in U251 cells transfected with pEGFP-PDCD4,whereas no PDCD4 mRNA and protein expression was detected in the non-transfected and vector-transfected cells.Further,cells transfected with pEGFP-PDCD4 grew more slowly and had lower colony formation rate than cells of the other two control groups(P

Objective To investigate the regulatory effects of Zishen Yutai Pills on the expression levels of homeboxA10 (HOXA10) and its downstream target gene empty spiracles homebox 2 (EMX2) in the endometria of ovulation-inducing mice at different implantation stages. Methods Seventy-five estrous female Kunming mice were randomly divided into 5 groups, namely normal group, model group 1, model group 2, treatment group 1, treatment group 2, 15 mice in each group. The model group 1 was given short-term protocol for ovulation induction; the model group 2 was given long-term protocol for ovulation induction; the treatment group 1 was given Zishen Yutai pills (at the dose of 0.4 g/mL) on the basis of the protocol for the model group 1; the treatment group 2 was given Zishen Yutai Pills (at the dose of 0.4 g/mL) on the basis of the protocol for the model group 2; the normal group was given intragastric administration or intraperitoneal injection of the same volume of normal saline. The mRNA and protein expression levels of HOXA10 and EMX2 in mouse uterus were detected by real-time fluorescent quantitative polymerase chain reaction (qPCR) and Western blot method, respectively. Results Compared with the normal group, the mRNA and protein expression levels of HOXA10 were decreased, and the mRNA and protein expression levels of EMX2 were increased in model group 1 and model group 2(P< 0.01). Compared with the corresponding model group 1 and 2, the mRNA and protein expression levels of HOXA10 were significantly up-regulated (P < 0.01) , and the mRNA and protein expression levels of EMX2 were decreased in the treatment group 1 and 2 (P < 0.01), respectively. Conclusion Zishen Yutai Pills may improve mouse endometrial receptivity by up-regulating HOXA10 expression and inhibiting EMX2 expression.

Objective To investigate the adaptive immune responses in elderly patients with chronic obstructive pulmonary disease during acute exacerbations (ECOPD) and effects of the immunostimulating agent Pidotimod in ECOPD patients. Methods A randomized, prospective clinical trial was held, and 103 patients with ECOPD were recruited into the study. Seventy-five patients aged 65 years and over were divided into two groups: 38 patients with general treatment as a control group and 37 patients with general treatment plus pidotimod as an experimental group. Another non-elderly groups comprised 28 patients younger than 65, and 20 healthy individuals served as the healthy elderly control. Levels of CD3+ , CD4+ , CD8+ , CD4+ /CD8+ in peripheral blood were measured by flow cytometry at baseline (the 1st day) and at the 15th and 30th treatment day, meanwhile, the clinical conditions were evaluated. Results Ninety-one patients completed the trial (32 in experimental group,34 in control group and 25 in non-eldely group). The experimental group and control group were statistically homogeneous. The aged COPD intervention group and aged COPD control had a more decreased CD4+ level, CD4+/CD8+ ratio and more increased CD8+ level, while compared with aged health control and non-elderly COPD control (all P
