In this paper, the presentations of 2D-color Doppler ultrasound imaging in 43 patients with rheumatic mitral lesion were studied before the replacement of artificial valve.The size of mitral opening, and several hemodynamic semiquan-titativc values were measured in diseased heart.Having analysed the features of valvular lesions, we consider that the 2D-color Doppler ultrasound can demonstrate the characteristics and ths degree of the valvular damage in one or several sections rapidly and directly. Therefore it is a very valuable method for diagnosing the rheumatic valvular lesion.

ObjectiveTo study the impact of stroke on elderly's mental status.Methods71 elderly inpatients aged between 60 to 90 who suffered stroke(31 cases) or not(40 cases) were assessed the mental status as a whole, the evaluation of comprehension of linguistic information,and non-verbal reasoning abilities using Mini Mental State Examination(MMSE), Token Test and Raven Test.The relationships between these cognitive aspects and stroke was also analysed.ResultsThere were 68% of elderly suffering dementia symptoms in stroke group which was much higher than Non-stroke group (15%).The correlation between MMSE and Token is more close than the correlation between MMSE and Raven in stroke group. The correlations among MMSE, Token and Raven were significant different between stroke and Non-stroke groups. There is a positive correlation coefficient between age and Token scores in dementing patients; whereas a closer relationship between age, education level and Raven in Non-stroke group was found. This implied the impacts of stroke on the time-course of mental degeneration.Conclusions stroke can interrupt normal mental structure and speed up the process of degeneration of cognitive functions. Semantic dysfunction might manifestation earlier than non-linguistic functions. Token is more sensitive than Raven in detecting dementia symptoms of stroke type.

Objective To investigale the quality of life (QOL) and its influenced factors in Tibetan patients with generalized tonic clonic epilepsy.Methods QOL of 126 definit diagnosed Tibetan patients with generalized tonic clonic epilepsy were measured with the QOL in Epilepsy Inventory-31 (QOLIE-31). The influenced factors of QOL were analysed. Results The total score of QOLIE-31 was 48.58?17.29; the lowest subcomponent score was 32.92?22.97 for Seizure Worry ; the highest was 77.11?20.98 for Medication Effects. Single factor analysis results were indicated that the scores of QOL between the different gender, occupation, marital status age,education were remarkable difference(all P

Objective To observe the inhibition effect of selective cyclooxygenase-2 inhibitor (celecoxib) on the experimental choroidal neovascularization (CNV).Methods Thirty 8-10 weeks old healthy male Brown-Norway(BN) rats were randomly divided into the control,laser and celecoxib group,with 10 rats in each group.At the dosage of 50 mg/kg,celecoxib was garaged twice per day.After 7 days,experimental CNV was induced by Krypon laser on laser group and celecoxib group.Fundus fluorescein angiography (FFA) was performed on days 3,7,14,21,30 after laser photocoagulation.On days 21 after photocoagulation,5 rats in each group were sacrificed and the relative thickness of CNV membranes,the expression of COX-2,vascular endothelial growth factor(VEGF) and matrix metalloproteinase-2 (MMP-2) Were studied by histopathologic or immunohistochemistry examination.Results On days 21 after photocoagulation,the incidence of CNV in the celecoxib group is significantly lower than that in the laser group (X~2=7.1068,P=0v0077);the relative thickness of the CNV membranes in the celecoxib group is reduced 41.38% compared to the laser group,the difference is statistically significant (t=16.7600,P=0.0000).COX-2,VEGF and MMP-2 expression in the CNV membrane of celecoxib group were significantly lower than in control group (t=5.7100,5.8400,8.0200;P=0.0000);the COX-2,VEGF and MMP-2 expressions in choroid and retina of control group were weak.Conclusion Prophylactic celecoxib can reduce the expression of VEGF and MMP-2 by inhibiting COX-2,and prevent the CNV induced by laser photocoagulation.

Various collateral circulations were detected by 2D color Doppler flow imaging(2DCDFI)in the part of 70 patients of liver cirrhosis with portal hypertension,including reopened umbilical veins,dilated focal intrahepatic veins,dilating,hepatofugal centrifugal hepatic blood flow in the portalveins,perisplenic and retroperitoneai varices etc.Red and blue blood flows were detected in the collateral circulations by 2D-CDFI and appeared as continuous venous spectrum with low velocity blood volume could be calculated to evaluat the therapeulic effectiveness of portal-systemic shunt operation.

This study was aimed to explore the clinical efficacy of Shen-Kang Injection (SKI) combined with hemodialysis in the treatment of chronic renal failure (CRF) patients. A total of 41 end-stage CRF patients under the hemodialysis treatment were randomly divided into the SKI treatment group of 19 cases and a control group of 22 cases. Both groups were treated with standard dialysis and the hemodialysis was maintained in the same symp-tomatic treatment conditions. Patients in the control group underwent three hemodialysis treatments in one week, while those in the treatment group were given hemodialysis twice a week based on the symptomatic treatment. And SKI was given after each time of hemodialysis in the treatment group. Indexes and changes in serum creati-nine (Scr), blood urea nitrogen (BUN) level, dialysis adequacy, nutrition status, traditional Chinese medicine ( TCM ) syndrome and other aspects of both groups were observed . The results showed that in the treatment group and control group, there were no significant differences in the renal function, dialysis adequacy, nutrition indica-tors and electrolyte ( P > 0 . 05 ) . In the treatment group , the total efficiency of TCM syndrome was 84 . 21%. And the total efficiency of TCM syndrome in the control group was 45.45%. The treatment group was better than the control group (P < 0.05). Symptoms such as scaly dry skin, numbness of the four limbs and dry stool were not obviously improved . And there was no statistical significance ( P > 0 . 05 ) . Symptoms such as fatigue , shortness of breath, poor appetite, dizziness, headache, lower back pain and spontaneous sweating were improved significantly. And there was statistical significance ( P < 0 . 05 ) . The treatment group was better than the control group . There were no abnormalities in the routine tests of blood, urine and stool, electrocardiogram, liver function, renal func-tion and electrolyte. In the treatment group, there was no significant adverse reactions during patients received SKI. The SKI has good safety. It was concluded that SKI combined with hemodialysis in the treatment of CRF is able to improve the clinical symptoms of patients and improve the patients' quality of life. When patient received adequate dialysis, SKI may reduce the dialysis frequency per week.

Objective To examine if high-dose glucocorticoid has any cerebral protective effects aftercardiopulmonary resuscitation. Methods Twenty-one healthy mongrel dogs of both sexes weighing 10 .5-15 kg weresubjected to cerebral ischemia using Pittsburgh standard ventricular fibrillation-cardiac arrest (VF-CA) model. Theanimals were anesthetized with intraperitoneal pentobarbital sodium 30 mg?kg~(-1) and mechanically ventilated thertracheal intubation (V_T 15 ml?kg~(-1), RR 18-20 bpm). Right femoral vein was cannulated for fluid administration(lactated Ringer's solution 0. 15 ml?kg~(-1)?min~(-1)) and right femoral artery was cannulated for BP monitoring. ECGwas continuously monitored. The animals were randomly divided into 3 groups: group A received only routineresuscitation treatment (control, n = 5); group B received dexamethasone 5 mg?kg~(-1) (n = 8) and group Cmethylprednisolone 30 mg?kg~(-1) (n = 8) after successful cardiopulmonary resuscitation. 8 hours after resuscitationthe animals were anesthetized and three pieces of brain tissue were obtained from right parietal lobe for light andelectron microscopic examination and determination of dopamine (DA) and 5-hydroxy-tryptamine (5-HT) contentsusing high-performance liquid chromatography- electrochemical technique (HPLC- ECD ). Results The DA and 5 -HT contents in parietal lobe of cortex were significantly decreased in group B and C as compared with group A (P

Objective To explore the role of the autoantibodies against angiotensin Ⅱtype 1 receptor(AT1-receptor) and ?1-adrenergic receptor(?1-receptor)in the development of chronic glomerulonephritis(CGN) with renal failure.Methods The epitopes of the second extracellular loop of AT1 receptor(165-191),?1 receptor(192-21),M2 receptor(169-191) were synthesized and used respectively to screen sera autoantibodies from patients with chronic renal failure(n=66),hypertension without renal failure(n=58) and healthy blood donors(n=40,control) by ELISA.Results In patients of chronic glomerulonephritis with renal failure,the positive rates of the autoantibodies against AT1-receptor and ?1-receptor were 56.1% and 53.0% respectively.The positive rates were all higher than those in patients of the hypertension without renal failure(the positive rates were 15.5% and 12.1%,respectively) and in the healthy donors(10% and 12.5%,respectively)(P
