Aiming at motion artifacts and off-resonance artifacts in multi-shot diffusion magnetic resonance imaging (MRI), we proposed a joint correction method in this paper to correct the two kinds of artifacts simultaneously without additional acquisition of navigation data and field map. We utilized the proposed method using multi-shot variable density spiral sequence to acquire MRI data and used auto-focusing technique for image deblurring. We also used direct method or iterative method to correct motion induced phase errors in the process of deblurring. In vivo MRI experiments demonstrated that the proposed method could effectively suppress motion artifacts and off-resonance artifacts and achieve images with fine structures. In addition, the scan time was not increased in applying the proposed method.

Objective To evaluate the value of intraduetal ultrasonography (IDUS) in diagnosing biliary and pancreatic disorders. Methods The findings by endoscopic retrograde cholangiopancreatography (ERCP) and IDUS from 19 patients with suspected biliary and pancreatic disorders from July 2006 to August 2007 in our hospital were analyzed retrospectively. Results Of the 19 patients, 17 had obstructive jaundice (including 6 eases of cholangiocarcinoma, 2 pancreatic adenocareinoma, 2 gallbladder carcinoma, 2 chole-docholithiasis with bile duct stricture, 2 autoimmune pancreatitis, 1 papillary adenocarcinoma, 1 papillary adenoma, and 1 sclerosing cholangitis) and 2 intraduetal papillary mueinous tumor (IPMT). The diagnosis was confirmed by surgery and pathological findings in 11 patients. The diagnostic accuracy of ERCP and IDUS was 73. 7% (14/19) and 84. 2% (16/19), respectively, and that of ERCP combined with IDUS was 89. 5% (17/19). The sensitivity and specificity of ERCP to differentiate benign bile duct strictures from ma-lignant ones were 100. 0% (11/11) and 83.3% (5/6), respectively; and those of IDUS were 100. 0%(11/11) and 100. 0% (6/6), respectively. The sensitivity and specificity of ERCP in diagnosing cholan-gioeareinoma were 83.3% (5/6) and 60% (3/5), respectively; and those of IDUS were 100. 0% (6/6) and 40. 0% (2/5), respectively. Conclusion Combination of ERCP with IDUS can improve the diagnostic accuracy of pancreaticobiliary disorders. Additionally, IDUS shows higher sensitivity and specificity in differ-entiation between benign and malignant bile duct strictures, but it is still difficult to identify the etiologic factors of malignant bile duet strictures by IDUS.

The construction of characteristic talent training program is crucial to strengthening the development of independent college.During the construction process,efforts should be made in the following aspects:the training aim being the inheritance of its matrix with the emphasis of application ; the curriculum system emphasizing skill training as well as improvement; the training model design making full use of resources with sufficient practice; the quality improvement highlighting regional characteristics and inheriting culture.Besides,special attention should be paid to understanding the government's relevant policies,to studying relevant theories about higher education and to grasping the generality of the education aimed at undergraduates and individuality of talents in independent college.

Objective To explore the influence of homocysteine(Hcy)on liver cystathionine-?-synthase(CBS)and methylenetetrahydrofolate reductase(MTHFR)system in apoE-/- mice,and determine the effects of atorvastatin and/or folate/vitamin B12 on liver CBS and MTHFR system.Methods Eighty male 6-week-old apoE-/- mice were randomly divided into two groups:65 mice were fed with a chow diet containing 2%(wt/vol)L-methionine(homomethionine group)and 15 mice were fed with normal saline(control group).Two months later,the 60 mice survived in homomethionine group were subdivided into four groups:group Ⅰ(untreated),Ⅱ(3 mg/kg atorvastatin),Ⅲ(3 mg/kg atorvastatin+2 mg/kg folate+30 ?g/kg vitamin B12)and Ⅳ(2 mg/kg folate+30 ?g/kg vitamin B12).After one month,Western blotting was performed to detect the liver CBS and MTHFR system protein expression in each group.Results The relative expression of liver CBS and MTHFR was significantly lower in group Ⅰ than in control group(P

Compared with the transgenic approach, transient assays provide a convenient alternative to analyze gene expression. To analyze the relationship between miRNAs and their target genes, a rice protoplast system to detect target gene activity was established. The MIRNA and GFP-fused target sequence (or GFP-fused mutated sequence as a non-target control) were constructed into the same plasmid, and then delivered into rice protoplasts. The GFP expression level decreased significantly when the protoplasts were transfected with the plasmid containing GFP-fused target compared to that of the plasmid with non-target sequence either by fluorescence microscopy or qRT-PCR method. Two microRNA genes, osaMIR156 and osaMIR397, and their target sequences were used to prove the feasibility of the rice protoplast transient assay system. This method will facilitate large-scale screening of rice miRNA target in vivo, and may be suitable for functional analysis of miRNAs of other monocot plants that might share the evolutionarily conserved small RNA processing system with rice.
