Vascular cognitive impairment (VCI) is a large class syndrome caused by a variety of cerebrovascular diseases from mild cognitive impairment to dementia.In the VCI animal experiments,choosing a reliable test method is particularly important for evaluating animal cognitive function and the improving the quality of animal models.

A harmonious physician-patient relationship is closely correlated with hospital culture construction.This paper explores the correlation from the perspectives of roles in building up decent fame of hospitals,promoting the construction of medical ethics,cultivating a fine humanistic medical atmosphere,strengthening the social responsibility of hospitals,and further clarifies the important function of hospital culture construction in constructing a harmonious physician-patient relationship.

Objective To study the electrochemical features of an improved enzyme bioelectrode for biofuel cell. Methods The enzyme electrode was prepared via biotin-avidin technology and its electrochemical features were explored. The conditions such as layers of enzyme films, strength of glucose, scan speed and temperature, which affected the electrochemical behavior of enzyme electrode, were studied. Results The results showed that the electrode had good electric current response to glucose. The enzyme electrode prepared can fulfill the need of biofuel cell and is a promising electrode to be used in human body.

Chinese medicine and traditional health care are valuable cultural heritage in our country,it proves the theory and practice of the two all play an enormous role in the mankind's health for centuries,theories of the two all have a close connection.

Objective To investigate the indication, methods and therapeutic effects of breast-conserving surgery in mammary cancer of early stage. Methods A retrospective study on 28 cases of Ⅰ and Ⅱ stage of breast-conserving surgery was underwent. Results Breast-conserving surgery does not destroy the appearance symmetry of breast, and maintains a low baldness rate. The recurrence rate in 5 years after surgery is 5.3%, and the 5 years' survival rate is 100%. Conclusion Breast-conserving surgery combined with the hinese herbal medicine therapy is an effective and safe way to treat mammary cancer in a early stage.

Relative problems in the management of HIV antibody primary screening lab are discussed, including laborato-ry building, staffing and training, equipment management, document management, reagent management, quality control and security protection. It is pointed out that the standardized laboratory management is an important part of the HIV antibody primary screening lab's quality Control.

Objective To evluate Feridex-enhanced MRI in the diagnosis of focal hepatic lesions. Methods Conventional plain and Feridex-enhanced MR scanning was performed in 20 cases with suspected hepatic neoplasm.The number of lesions on T 2WI ,and the signal intensity of liver and lesions demonstrated on plain and enhanced scans were observed and analyzed.Results After the injection of Feridex,the signal intensity of normal liver tissue reduced significantly,while the signal intensity of lesions showed no marked changes,Feridex-enhanced MRI clearly displayed more lesions on T 2WI than plain scanning did.Conclusion Feridex-enhanced MRI is very sensitive in detecting focal hepatic lesions.

Objective To evaluate the dynamic imaging alteration of radiation-induced hepatic injuries after stereotactic radiotherapy (SRT) in hepatocellular carcinoma.Methods 18 healthy New Zealand white rabbits inoculated VX_2 carcinoma underwent 40 Gy SRT and divided into three groups randomly.The rabbits underwent identical plain and enhanced MR imaging after SRT 3 weeks,9 weeks and 20 weeks respectively. The signal-to-noise ratios of irradiation area and the surrounding normal liver on T_1WI and T_2WI imaging were calculated;The percentage enhancement of the hepatic injuried areas and the surrouding livers after Gd-DTPA enhanced was also calculated.Results After radiotherapy three weeks, the signal-to-noise ratios of irradiation areas on T_1WI and T_2WI were no difference between normal liver tissue and irradiation area; there were significant difference between normal liver tissues in radiotherapy nine weeks and twenty weeks; The difference in the signal-to-noise ratios of irradiation area were significant between after three weeks and nine weeks, twenty weeks. There were no difference in the signal-to-noise ratios of irradiation area between nine weeks and twenty weeks.The percentage enhancement of the hepatic injuries area have significant difference in arterial phase between three weeks and twenty weeks and between nine weeks and twenty weeks;The difference in portal and delay phase were significant between three weeks and nine weeks, twenty weeks, there were no difference between nine weeks and twenty weeks.Conclusion Dynamic enhanced and unenhanced MR imaging can reflect the pathological background of radiation-induced hepatic injuries in different phases.

[Objective]To explore the therapeutic effect of the posterior-anterior approach surgical treatment for severe cervical spondylotic myelopathy.[Method]Totally 32 patients with severe cervical spondylotic myelopathy operated by posterior-anterior approach surgical treatment from September in 1998 to January in 2005 were retrospectively analyzed.In the 32 patients,20 males and 12 females.Their age averaged 53.8 years(ranged,41~78 years),invasional segments:C3、42 cases,C4、5 9 cases,C5、611 cases,C6、7 10 cases.Four cases with lesions involving one intervenebral space,the other 12 and 16 cases involving two and three intervertebral spaces respectively.All cases had the posterior cervical open-door laminoplasty decompression in first,and had the anterior cervical decompression and bone grafting or fusion with titanium Cage internal fixation after a week.To follow up all the postoperative cases,neural function was recorded.According to JOA score,preoperative score and postoperative follow-up score were compared,improvement rates were caleulated respectively.[Result]All cases were regularly followed up.The duration of follow-up averaged 13.6 months(ranged,12~18 months).The JOA of before operation was(6.51?1.10),the JOA of first period of time after operation was(9.47?0.5),and follow-up JOA was(12.42?0.79).T-test was used to compare pre-operative and follow-up JOA scores.The statistical results were significantly different(P
