[Objective] To study the relevance between “Sui-hai deficiency” and classification vertebral artery caused by less blood provide with morphological changes.[Method] 84 cases accord with the diagnosis standard of vertebral artery,all these patients were tested morphological changes by a three dimensional computed topographic angiograpy(3D-CTA),and then measured by transcranial Doppler(TCD)to test the changes of blood,research mechanism of “Sui-hai deficient” vertigo.[Results]168 vertebral arteries of 84 cases in this group,low flow speed(Vm40cm/s)was18.45%,and the abnormal rate was 66.07%.126 vertebral arteries morphological abnormal rate was 75%.Changes of low flow speed was 63.50%,high flow speed was 24.60%,the abnormal rate was 88.10%.[Conclusion] Morphology of vertebral arties changes is the direct reason to make the defficiency of vertebral artery.Morphological changes → blood flow abnormal → vertebral artery with less blood provide → “Su-hai deficient” → vertigo,which is the major cause of vertigo.

This paper summarizes the perioperative nursing of 65 patients undergoing eyelid malignant tumor resection combined with primary eyelid reconstruction. The nursing care focused on routine preoperative preparations as well as postoperative care of incision dressing, dressing change, medication administration and monitoring, prevention of infections and health education. All the patients had Ⅰ-phase wound healing and good shape of eyelid repair without postoperative complications.

Objective To explore the relationship between the common vascular risk factors and cerebrovascular reserve in the aged patients.Methods 700 patients with sex unlimited were selected from Zhejiang Hospital from July 2007 to July 2010.The clinical data about gender,age,smoking history,drinking history,hypertension,diabetes,dyslipidemia,bilateral carotid artery B ultrasonic examination were collected.The patients were divided into vascular risk factors group(n=400)aged(73.4± 6.8)years and control group(n=300)aged(72.4± 6.9)years.Intracranial vascular reaction was dertermined using transcranial doppler ultrasonography combined with breathholding test to calculate the breath-holding index(BHI)and evaluate cerebrovascular reserve.Results BHI in vascular risk factors group and control group were(0.57±0.18)and(0.97±0.31),respectively,and cerebrovascular reserve in the patients with vascular risk factors was decreased than without risk factors(t =10.87,P ＜ 0.01).Multifactor retrospective analysis showed hypertension,hyperlipidemia,diabetes and smoking were related with cerebrovascular reserve(F=6.51,P =0.000),and the degree to influnce from small to large was followed by diabetes,hypertention,smoking and hyperlipidemia.Conclusions Cerebrovascular reserve is damaged in the aged patients with vascular risk factors.Hypertension,hyperlipidemia,diabetes,smoking may affect cerebrovascular reserves among which the greatest influence is in diabetes.

Objective:To investigate the accuracy of magnetic resonance imaging (MRI) cine sequences in determining the range of tumor motion in radiotherapy, providing a basis for the precise delineation of the target volume in motion for radiation therapy.Methods:A modified chest motion phantom was placed in a MRI scanner, and a water-filled sphere was used to simulate a tumor. True fast imaging with steady precession (TrueFISP) MRI cine sequences from Siemens were used to capture the two-dimensional motion images of the simulated tumor. The phantom experiments were divided into three modes: head-foot motion mode, rotation motion mode, and actual respiratory waveform mode. In the head-foot motion mode, respiratory motion period (3, 4, 5, 6, 7 and 8 s), amplitude (5, 10 and 15 mm), and respiratory waveform of the simulated tumor (sin and cos4) were set, resulting in a total of 36 motion combinations. In the rotation motion mode, a cos4 waveform was used for respiration, with respiratory periods of 3, 4, 5, 6, 7 and 8 s, head-foot motion set amplitudes of 5, 10 and 15 mm, and anterior-posterior (AP) and left-right (LR) motion set amplitudes in three combinations ([2.5, 2.5] mm, [2.5, 5.0] mm, [5.0, 5.0] mm), resulting in a total of 54 motion combinations. In the actual respiratory waveform mode, respiratory waveforms of 5 randomly selected patients from Affiliated Cancer Hospital of Zhengzhou University were obtained. Under each motion combination, TrueFISP cine images (30 frames, with an acquisition time of 11 s per frame) were obtained. The code was used to automatically identify the two-dimensional coordinates of the center of the simulated tumor in each image, and sin and cos4 functions were separately employed to fit the tumor position in the motion direction, thereby obtaining the fitted motion period and amplitude. The difference between the maximum and minimum values of the tumor's center coordinates in the head-to-foot direction is taken as the range of movement, referred to as the calculated amplitude. For the actual respiratory waveform, the distance between the measured maximum and minimum positions is used to calculate the amplitude.Results:In the head-foot motion mode, the fitted amplitudes of both sin and cos4 waveforms deviated from the set amplitudes by 0-0.51 mm, with relative deviations of 0%-4.2%. The deviation range between the calculated amplitudes and the set amplitudes of the two waveforms were 0.08-0.94 mm, with relative deviations of 1.1%-6.3%. In the rotation motion mode, the fitted amplitudes deviated from the set amplitudes by 0-0.61 mm, with relative deviations of 0%-6.2%. And the deviation range between the calculated amplitudes and the set amplitudes were 0.16-0.94 mm, with relative deviations of 0%-6.3%. In the actual respiratory waveform motion mode, the deviation range between the calculated amplitudes and the set amplitudes were 0.10-0.48 mm, with relative deviations of 2.2%-8.6%.Conclusion:TrueFISP cine sequences show minimal deviations in determining the range of tumor head-foot motion and effectively captures the tumor's movement state, thereby providing important support for the precise definition of the tumor movement target area during radiotherapy .
