Background Intracranial vascular malformation causes different neurophthalmological symptoms and signs due to oppressing visual-related tissue and cranial nerves after hemorrhage.However,there is no availably systematic clinical research on this disease up to now.Objective This retrospective cases analysis was to explore the neurophthalmological features of intracranial vascular malformation.Methods The clinical datas were collected from 100 cases with intracranial vascular malformation in Affiliated Third Hospital of Sun Yat-sen University from June,2007 to June,2013.The neurophthalmological clinical features including general condition,initial symptom,concomitant symptoms and image results were retrospectively surveyed.Results Neurophthalmological symptoms and signs were found in 20 patients with intracranial vascular malformation by CT and MRI with the detectability 20％ (20/100).The main neurophthalmological symptoms were visual field defect (50％,10/20) and vision loss (45％,9/20).The neurophthalmological signs were pupil abnormalities (35％,7/20).Other neurophthalmological features included optic nerve atrophy (5 ％,1/20),papilloedema (5 ％,1/20) and oculomotor nerve palsy (5 ％,1/20),etc.The relevant cranial diseases included cerebral arteriovenous malformation in 60％ patients (12/20),cavernous angiomas in 35％ (7/20) and venous malformation with cavernous angiomas (1/20).The lesions of cerebral arteriovenous malformation were located in occipital lobe (4 cases),parietal-occipital area (3 cases),temporal lobe (3 cases) and frontal lobe (1 case),midbrain area (1 case) ; while those of cavernous angiomas were located in parietal lobe (1 case),occipital lobe (1 case),gyrus cingulated area occipital lobe (1 case),carvenous sinus (1 case),temporal lobe (1 case),parietal-temporal area (1 case) and pons area (1 case).Intracranial hemorrhage occurred in 14 patients in subarachnoid space (6 cases) and brain (8 cases).Conclusions The patients with intracranial vascular malformation have different neurophthalmological symptoms and signs.Sufficient attention should be paid to the patients with neurophthalmological symptoms and signs.

The left ventricular regional systolic functions in patients with hypertrophic cardiomyopathy (HCM) were assessed by using quantitative tissue velocity imaging (QTVI). Left ventricular (LV) regional myocardial velocity along long- and short-axis in 31 HCM patients and 20 healthy subjects were analyzed by QTVI, and the regional myocardial systolic peak velocities (MVS) were measured. Mean MVS at each level including mitral annular, basal, middle and apical segments were calculated. The ratio of MVS along long-axis to that along short-axis (Ri) at basal and middle segments of the LV posterior wall and ventricular septum were calculated. The results showed that mean MVS was slower at each level including mitral annular, basal, middle and apical segments in the HCM patients than that in the healthy subjects (P < 0.01). There were no significant differences in mean MVS between obstructive and non-obstructive groups in HCM patients. MVS of all regional myocardial segments along long-axis in the HCM patients were significantly slower than that in the healthy subjects (P < 0.05), but there was no significant difference in MVS of all regional myocardial segments along long-axis between hypertrophied and non-hypertrophied group in the HCM patients. Ri was significantly lower in the HCM patients than that in the healthy subjects. The LV regional myocardial contractility along long-axis was impaired not only in the hypertrophied wall but also in the non-hypertrophied one in patients with HCM, suggesting that QTVI can assess accurately LV regional systolic function in patient with HCM and provides a novel means for an early diagnosis before and independent of hypertrophy.

Objective:To develop a negative emotion screening scale for inpatients(NESSI) and test its validity and reliability.Methods:Based on our previous studies and the theory model of psychological stress, the original item pool was established through literature review, expert interviews and patient consultation.The first version of NESSI was constructed by Delphi method, then initially tested in 421 inpatients followed by the project analysis and reliability test. After those above, the formal scale was developed and tested in 318 inpatients followed by confirmatory factor analysis and reliability test.Finally, 7-item generalized anxiety disorder scale (GAD-7), 9-item patient health questionnaire (PHQ-9), anger state expression scale (SAS) and simplified Chinese version of fear of disease progression scale(FoP-Q-SF) were used to test the criterion validity.Results:After exploratory factor analysis, 17 items were retained in the final scale, which can be categorized into four dimensions: fear of illness, depression, somatization and anger, which could explain 63.49% of the total variation.Confirmatory factor analysis showed that the fitting degree of each factor model was good and met the requirements of reference value (χ 2/ df=2.949, RMR=0.044, CFI=0.929, NFI=0.897, IFI=0.930, TLI=0.915, PGFI=0.655, RMSEA=0.078). The Cronbach's α coefficient of the total scale was 0.925, and the Cronbach's α coefficient of the four factors ranged from 0.762 to 0.898.The criterion validity showed that there was a significant positive correlation between the scale and the four criterion scales ( r= 0.574-0.805, all P<0.01). Conclusion:The NESSI scale has good reliability and validity, and can be used as a psychological problem screening tool among non-psychiatric inpatients.

To examine the role of nitric oxide in the beta-adrenergic vasodilation of epicardial coronary arteries in dogs, 12 dogs were instrumented for measurement of left anterior descending coronary artery diameter by transthoracic echocardiography before and after dobutamine (5 microg/kg/min IV) with and without intracoronary infusion of NG-monomethyl-L-arginine (L-NMMA) (1 mg/kg). In all 12 dogs, the diameter of left anterior descending coronary artery increased significantly from 2.35 +/- 0.25 mm to 2.59 +/- 0.24 mm (P<0.001) after dobutamine administration. In 6 of the 12 dogs, the percent change in left anterior descending coronary artery diameter induced by dobutamine decreased significantly from 12.5% +/- 8.6% to -1.5% +/- 5.4% (P<0.05) after the administration of intracoronary L-NMMA (1 mg/kg for 5 min) to block nitric oxide synthesis from L-arginine. The study demonstrated that nitric oxide formation contributes to the beta-adrenergic dilatory response of epicardial coronary arteries to dobutamine in dogs.

To assess the left ventricular longitudinal regional myocardial systolic function by strain imaging (SI) echocardiography and to study the relationship between regional myocardial systolic function and left ventricular structure in patients with hypertrophic cardiomyopathy (HCM). SI echocardiography were performed in 18 patients with HCM and 17 healthy subjects. For each wall,regional myocardial systolic strain was analyzed at the basal, mid, and apical level respectively.And the peak systolic strain was measured. Our results showed that the patients with HCM had reduced peak systolic strain at almost each segment of different walls when compared with healthy subjects. There was significant correlation between the mid-septum peak systolic strain and the thickness of IVS, so was the correlation between the mid-septum peak systolic strain and the IVS to LVPW thickness ratio. This study demonstrated that the left ventricular longitudinal regional myocardial systolic function was abnormal in HCM, and this kind of abnormalities existed extensively in hypertrophic and non-hypertrophic cardiac segments. The degrees of left ventricle hypertrophy and asymmetry are related to the myocardial regional systolic function in HCM.
