Objective To prospectively evaluate 3D time-of-flight magnetic resonance angiography (3DTOF MRA) and high resolution contrast enhanced volume scan magnetic resonance angiography (CEMRA) with sensitivity encoding in diagnosing craniocervical artery stenosis. Methods Forty-six patients suspected with craniocervical artery diseases underwent MRI, 3DTOF MRA of the head and also CEMRA of the neck. The images of MRA were reconstructed with MIP and VR. The degree of arterial stenosis demonstrated on MRA was compared with that showed on digital subtraction angiography(DSA), and the data were analyzed with Spearman rank correlation coefficient (Rs). Results Excellent correlation in determining the degree of craniocervical artery stenosis existed between MRA and DSA (Rs = 0.97). With DSA as a golden standard, the sensitivity, specificity and accuracy of MRA in detecting over 50% arterial stenosis were 100%, 99.4% and 99.4% respectively. Conclusion 3DTOF MRA and CEMRA with sensitivity encoding at 3.0T are reliable and effective examinations for evaluating craniocervical artery disease. These techniques can be used as the necessary exams before DSA and can even substitute for the conventional DSA in some instances.

Abstract: In order to investigate immune protection against swine-origin influenza virus (S-OIV) A H1N1, the helper-dependent adenovirus vector (HDAd) system was exploited to construct recombinant HDAd encoding hemagglutinin (HA). The HA gene was synthesized and cloned to the HDAd backbone. Then, the HDAd/HA DNA molecules were transfected into 293Cre4 cells with calcium phosphate. The cells were infected by helper virus 16 hours after the transfection. The 293Cre4 cells were coinfected with HDAd/HA and the helper virus for large-scale preparation of HDAd/HA. The HDAd/HA was obtained and purified twice with CsCI density ultracentrifugation and observed morphologically under transmission electron microscope, and the expression of HA protein was analyzed with RTPCR. Recombinant HDAd/HA expressing HA protein was successfully constructed which could pave the way for in vivo investigation on immunogenicity and efficacy against S-OIV A H1N1 infection.

AIM: To compare intraocular pressure (IOP) fluctuations measured at home and in the clinic over a 24-hour period.METHODS: A prospective investigational study.A total of 120 Chinese participants were selected from five communities in the Chengdu area.Patients underwent a clinical interview and IOP was measured both at home and in the clinic.IOP were measured at 8 a.m., 10 a.m., 12 a.m., 2 p.m., 4 p.m., 6 p.m., 8 p.m., 10 p.m., 2 a.m., 6 a.m.using the same pneumatonometer.Measurements were taken in the sitting position.RESULTS: The average 24-hour IOP measured in the clinic was slightly lower than that at home.The mean difference in 24-hour IOP measurements between home and clinic was 0.27 mmHg.The IOP fluctuation in the clinic was higher than at home (the mean difference was 0.01 mmHg).There was no statistically significant difference in the average 24-hour IOP measured at home vs in the clinic.The average IOP measured at 2 p.m.at home (16.04±5.95 mmHg) was significantly higher compared with the measurement in the clinic (15.43±5.16 mmHg) (P<0.05).The overall agreement between 24-hour IOP measurements made in the clinic and at home in diagnosis of primary open angle glaucoma was 85.0% (K coefficient: 0.68).CONCLUSION: The 24-hour IOP measured in the clinic was similar to that measured at home, and the method of measuring IOP in the clinic is acceptable in diagnosing primary open angle glaucoma.

AIM: To investigate the time - effect relationship between the expression of rhodopsin and recoverin and photoreceptor damage induced by N - nethl - N -nitrosourea ( MNU) .
METHODS: Thirty-six 7-week old Sprague-Dawley ( SD ) rats were intraperitoneally injected with MNU ( 60mg/kg ) and were put to death by dislocation of cervical vertebra 6, 12, 24h; 3, 7d after injection ( 6 per group) , respectively. As a control, six rats were injected with phosphate buffer saline (PBS) 5mL/kg and sacrificed on d3 after injection. The degree of photoreceptor apoptosis was detected by HE staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling ( TUNEL ) and transmission electron microscope ( TEM ) in the right eyes. The mRNA expressions of rhodopsin and recoverin were detected different time after injection by Western blot and immunohistochemical method in the left eyes.
RESULTS:The dissolution of photoreceptor nucleus and apoptosis body were first perceived at 12h by TEM; most of cells at outer nuclear layer were presented positive reaction. The apoptotic index reached peak ( 29. 7% ±2.3%) at 24h which was coincided with the observation of TEM. The results of immunohistochemistry displayed that rhodopsin and recoverin were on a declining curve with time extension. Furthermore, the results of Western blot indicated that rhodopsin had dramatic decline at 6h after injection (P<0. 05), and extremely significant difference comparing to control group after 12h ( P<0. 01 ); while recoverin dramatic declined at 12h, and extremely significant difference after 24h (P<0. 01).
CONCLUSION:60mg/kg MNU intraperitoneally injection one - time may specifically induce photoreceptor apoptosis, The mechanism of down - regulation of rhodopsin and recoverin may be related to the selected apoptosis of photoreceptors.

Background The condition of the sclera is associated with many ocular diseases.The measurement of human scleral thickness in vivo is helpful for us to understand the features of the sclera and related diseases.Objective The present study was to measure the anterior sclera thickness(AST) in patients with senile cataract and to analyze the relationship among AST and other associated ocular parameters.Methods This study was approved by the Ethic Commission of First Hospital of Peking University.Written informed consent was obtained from each individual prior to examination.One hundred and five senile cataract patients were recruited in this study.Central corneal thickness (CCT),corneal curvature (CCV) and axial length were measured using ultrasonic pachymeter,keratometer,and A-scan unit,respectively.The AST was measured at 2 mm posterior to the scleral spur in the temporal meridian using ultrasound biomicroscope (UBM).The differences of CCT,CCV,ocular axial length and AST between bilateral eyes and the different sexes were compared by the Paired test and independent sample t test.The correlations among various parameters were assessed by the Pearson linear correlation analysis.The differences of CCT and AST among different axial length groups were evaluated by one-way ANOVA.Results No significant differences were found in the CCT,CCV,axial length and AST between bilateral eyes (t =0.584,P =0.561 ; t =1.161,P =0.248 ; t =0.140,P =0.889 ; t =0.342,P =0.773).Temporal AST at 2 mm posterior to the sclera spur was (0.589 ±0.051)mm in the right eyes.An insignificant decline in CCT was found in the male group compared with the female group (right eyes:t =0.469,P =0.641 ; left eyes:t =0.465,P =0.643).However,compared with the female group,the increase of axial length,reduction of the mean CCV value and enhancement of the mean AST were observed(right eyes:all P＜0.01 ;left eyes:all P＜0.01).CCV showed a negative correlation with ocular axial length (r =-0.50,P＜0.01),but no significant correlation was found among age,CCT,ocular axial length and AST(P＞0.05).No remarkable differences were found in CCT and AST among the various axial length groups (CCT:F =0.998,P=0.372;AST:F=1.919,P=0.383).Conclusions In senile cataract patients,correlation is not found between AST and CCT;the increase of axial length is not associated with the thinning of the eyeball wall to a certain extent.Differences exist in some ocular parameters between different sexes.
