Objective To investigate the effect of lorsartan on rat model of atherosclerosis. Methods Totally 30 male Wistar rats were randomly divided to three different groups: control group, model group (high lipid + Vitamin D overload+ endothelium injury), and treatment group(high lipid + Vitamin D overload + endothelium injury + lorsartan). Rat model of atherosclerosis was established by high lipid plus Vitamin D overload plus baloon angioplasty-induced endothel ium injury, a nd animals in the treatment group were models treated with lorsartan. After 90 days the blood samples were drawn to examine the serum lipids and calcium, H-E staining was used to observe the structure changes of thoracic aorta, and immunohistochemistry assay was used to observe CD68 and cractin expression in the thoracic aorta. To study the relationship between Ang TJ and severity of AS, radio-immunity analysis was used to assay Ang TJ in each group, with the thickness of intima used as the index of AS severity. Results The serum levels of total cholesterol (TC), triglyceride (TG), LDL-C and serum calcium in model and treatment groups were significantly higher than those in the control group (P<0. 01). Compared with the control group, the model group had a thicker intima and thinner media. Compared with model group, the treatment group had a significantly thinner intima and thicker media (P<0. 01). Immunohistochemistry showed that CD68 was negative in the control group, strongly positive in the model group and weakly positive in the treatment group. Compared with model group, cractin positive level was higher in the treatment group. The serum Ang Tj levels were not significantly different between the three groups. Ang TJ level in the thoracic aorta tissue in the treatment group was significantly lower than that in control group and higher than that in the model group (P<0. 05). Ang E level in the thoracic aorta tissue was positively related with the intima thickness (P<0. 01). Conclusion Lorsartan has anti-atherosclerosis effect in rats.

Objective In order to offer a noninvasive and objective examination method for assessing the clinical diagnosis and eurative criterion of concussion patients, the patients color three - dimensional transcranial doppler( 3D - TCD) characteristic at deferent phases, parameter and clincal manifestation were studied Method Parameter of Median Cerebral Artery(MCA), Base Artery(BA), the average peak forwand velocity of cerebral blood flow, train figure were tested by 3D - TCD within 24 hours, 3 - 6 days and at the end of treatment, respectively. The results were compared with clinical diagnoses and curative criterion. Result Among 135 patients who had clinically diagnosed concussion, agreeable diagnoses 101 cases, basically agreeable diagnooses 12 cases, disagreeable diagnosis 22 cases(16. 2%) .At the end of treatment, according to clinical determination 96 cases(71.1%) were cured, 39 cases(28.9%) were improved. Wave train character, figure and diagnoses prameter of cerebral spasm caused by concussion were suggested Conclusion To be one of the diagnostic bases and curative criterion, 3D- TC D technology is performable. Meanwhile, it is a new testing objective technique for assessing curative and determining prognosis.

BACKGROUND:The micro-ecological environment has been broken when the ocular prosthesis was inset into the conjunctival sac. The recede of self cleaning function is more conducive to the microbial growth and colonization. The cleaning of plaque biofilm on ocular prosthesis surface affects the patient's wearing comfort and quality of life. It is necessary to seek an effective cleaning method. OBJECTIVE:To compare the clearance effect of five cleaning methods on the palque biofilm on ocular prosthesis surface. METHODS: The conjunctival secretions from 84 patients who were subjected to ocular prosthesis repair were taken for bacterial culture and identification. Fifty pieces of self-curing resin and thermosetting resin artificial eyes were produced. The artificial eyes in each group were randomly divided into five groups, and were cleaned respectively with clear water, volume fraction of 75% ethanol, Boston SIMPLUS, polident and toothpaste. After the completion of the cleaning, the test piece was conducted residual biofilm culture. The clearance effects of different processing modes were evaluated using colony counting method. RESULTS AND CONCLUSION: Eighty-four specimens were submitted for inspection, of which 49 were positive. The Staphylococcusaureus separation rate was 14.29%.Staphylococcus epidermidis separation rate accounted for 13.10%. Maxwel Corynebacterium separation rate accounted for 7.14%. When water, Boston SIMPLUS and toothpaste were used for cleaning, theStaphylococcus aureus colony number in the self-curing resin group was higher than that in the thermosetting resin group (P< 0.05); when ethanol and polident were used for cleaning, there was no difference in the Staphylococcus aureus colony number between these two groups. In self-curing resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). The colony count in the ethanol treatment group was lower than that in the Boston SIMPLUS group (P < 0.05). There was no significant difference in the colony count between other groups. In thermosetting resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). There was no significant difference in the colony count between other groups. These results demonstrate that ethanol, Boston SIMPLUS, polident and toothpaste have better cleaning effects onStaphylococcus aureusbiofilms on the surface of two kinds of ocular prostheses than the clear water rinse. Overal, it is encouraged to clean the artificial eyes using polident and Boston SIMPLUS, in order to avoid the occurrence of microbial infection in the conjunctival sac after wearing ocular prosthesis.

Objective To study the right ventricular function of patients with pulmonary thromboembolism by using color Doppler ultrasound.Methods 31 patients with acute pulmonary thromboembolism,compared with 31 vohnteers,were enrolled in this study.The right ventricular anterior wall movement,right ventricular end diastolic volume,right ventricular ejection fraction,and myocardial performance index were observed by echocardiography.Resuits The right atrium diameter,right ventricles diameter,right ventrieular end diastolic volume and pulmonary artery inner diameter in study group were much larger than that in control group (P<0.01),and the right ventricular anterior wall movement and right ventrieular ejection fraction decreased in study group (P<0.01).Tricuspidal annular E peak velocity tended to be decreased,isovolumie relaxation time and isovolumic contraction time were prolonged and myocardial performance index was increased (P<0.01).Right ventricular myocardial performance index showed significant correlation with right ventrieular ejection fraction (r=0.78,P<0.01),isovolumic relaxation time and isovolumic contraction time(rl=0.88,r2=0.57,P<0.01).Conclusion The right ventricular function in patients with pulmonary thromboembelism is decreased and myocardial performance index is a sensitive index which can be used to reflect right ventricular function in pulmonary thromboembolism.
