Objective To identify the correlation factors associated with cerebral intragenic ischemia after temporary parent arterial occlusion in intracranial aneurysm surgery. Methods One hundred and eighteen patients who underwent temporary arterial occlusion in the 120 aneurysms (from a group of 324 consecutive aneurysm patients treated from 1996 to 2002) were reviewed retrospectively. These variables included sex, age, presence of preoperative subarachnoid hemorrhage (SAH), neurological clinical grade, operational timing, duration of arterial occlusion, numbers of temporary occlusion, mode of arterial occlusion, intraoperative aneurysm rupture, hypertension, the location of temporary occlusion, aneurysm size, hyperglycemia, atheromatous mass. Univariate and multivariate were used to investigate the relationship between the variates and postoperative ischemic changes. Results The total times of temporary occlusion were 156, with an average of 1.30. The duration of arterial occlusion ranged from 1 to 45 min (9.75?7.75). Seventeen patients (14.4%) demonstrated evidence of new infarction in the vascular territory subjected to temporary arterial occlusion. Conclusion In the univariate analysis, age, presence of preoperative SAH, duration of arterial occlusion, atheromatous mass are all significantly correlated with postoperative ischemic injuries. Multivariate logistic regression revealed that the age, older more than 60 (P= 0.010 3 , relative risk=4.335), and the duration of arterial occlusion, lasting more than 20 min (P= 0.032 9 , relative risk=4.177), have significant correlation with the injuries. Based on these findings, temporary occlusion is safe and useful in aneurysm surgery and the postoperative cerebral ischemia is less likely to occur when the duration of clipping is shorter than 20 min.

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.

Objective To study the effect of abnormal left ventricular diastolic function(LVDF)on the onset and severity of atrial or ventricular arrhythmia in elderly essential hypertensive patients.Methods The 210 elderly essential hypertensive patients were enrolled in this study. Their arrhythmias were monitored by 24-hour ambulatory electrocardiogram. The essential hypertensive patients were referred for Doppler echocardiography to evaluate left ventricular function, while patients with abnormal systolic function were excluded, and then the patients were classified as normal LVDF and abnormal LVDF including, impaired relaxation, pseudonormal, and restrictivelike filling patterns. Results In 210 elderly essential hypertensive patients, 147 (70%) cases were diagnosed as atrial arrhythmia and 102 (49%) cases as ventricular arrhythmia (χ2 = 19. 975, P < 0.05 ).Morbidities of atrial (89%) or complex atrial arrhythmia (49%) as well as ventricular (63%) orcomplex ventricular arrhythmia (30%) were significantly higher in abnormal LVDN group than in normal LVDN group (40%, 13%, 26% and 7%, χ2 = 56. 723 、 28. 359 、 28. 076、15. 9102 , all P<0. 05). The morbidities of arrhythmias were higher in hypertensive patients with pseudonormal and restrictiveike filling patterns than in other groups 93.6% and 96. 4%. Conclusions Abnormal left ventricular diastolic function affects on the onset and severity of atrial or ventricular arrhythmia in elderly essential hypertensive patients, and complex atrial or ventricular arrhythmia is easier found in hypertensive patients with pseudonormal and restrictivelike filling patterns.

Objective To explore the correlation between hypokalemia and sudden death in young and middle-aged people. Methods One hundred and twenty-nine young and middle-aged patients with sudden death during treatment were selected as observation group. Then 100 cases of healthy volunteers were randomly selected as control group. The incidence of cardiovascular disease, incidence of hypokalemia and intake of potassium were compared between 2 groups. Results The incidences of hypertension, arrhythmia, myocardial infarction, heart failure and hypokalemia in observation group were significantly higher than those in control group: 17.05% (22/129) vs. 5.00%(5/100), 13.18% (17/129) vs. 2.00% (2/100), 26.36% (34/129) vs. 9.00% (9/100), 9.30% (12/129) vs. 1.00% (1/100) and 55.04% (71/129) vs. 12.00% (12/100), and there were statistical differences (P<0.01). The ratios of higher, common, lower intake of potassium in observation group were 1.55%(2/129), 27.91% (36/129) and 70.54%(91/129), in control group were 15.00% (15/100), 58.00% (58/100) and 27.00% (27/100), and there was statistical difference (P<0.01). Logistic regression analysis result showed that hypertension, arrhythmia, myocardial infarction, heart failure, hypokalemia and lower intake of potassium were the risk factor for sudden death (P<0.01). The incidences of hypertension, arrhythmia, myocardial infarction and heart failure in hypokalemia patients were significantly higher than those in normokalemia patients: 28.92% (24/83) vs. 2.05% (3/146), 19.28% (16/83) vs. 2.05% (3/146), 44.58%(37/83) vs. 4.11% (6/146) and 13.25% (11/83) vs. 1.37% (2/146), and there were statistical differences (P<0.01). The incidence of hypokalemia in people with lower intake of potassium was significantly higher than that in people with higher and common intake of potassium: 56.78% (67/118) vs. 2/17 and 14.89%(14/94), and there was statistical difference (P<0.01). Conclusions There is a significant correlation between hypokalemia and sudden death in young and middle-aged people. Preventive measures of sudden death should be made according to serum potassium level in clinic. People should pay attention to the uptake of potassium in daily life.

BACKGROUNDThe vertebral artery (VA) and atlantoaxial joint (AAJ), with complicated structures, are located in the depths of the head-neck boundary area, the regional anatomy of which cannot be shown globally and directly. This study aims to evaluate three-dimensional CT angiography (3DCTA) in displaying the AAJ, atlantoaxial segment of the vertebral artery (ASVA) and the identification of their interrelations.
METHODSSixty-eight subjects without pathology of the ASVA and AAJ were selected from head-neck CTA examination. All the 3D images were formed with volume rendering (VR) together with techniques of separating, fusing, opacifying and false-coloring (SFOF). On the 3D images, the ASVA and AAJ were observed, and their interrelations were measured.
RESULTSAll the 3DCTA images were of high quality and up to our requirements. They could clearly and directly show the ASVA, ascending along the AAJ. There were 5 curves in the course of the ASVA, of which 2 curves were away from the atlantoaxial joint, one in the 2nd curve of 0.0 mm - 5.4 mm, the other in the 4th of 2.6 mm - 9.2 mm. There was no significant difference in the measurements between left and right (P > 0.05). The curved parts of the ASVA slightly expanded, with the biggest diameter of 5.6 mm in the 4th curve. Statistical comparison shows that the left ASVA is larger than the right (P < 0.05). Variations of the ASVA were found in 8 cases and of the AAJ in 12.
CONCLUSIONS3DCTA can globally and directly demonstrate the structures of the AAJ, ASVA and their interrelations. The 3D imaging data make up and enrich the research contents of regional anatomy and lay the foundation for related study and applications.
