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.

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 explore expression of plasma omentin -1 in patients with central obesity (CO) complicated essential hypertension (EH) and its clinical significance .Methods : Serum level of omentin - 1 was measured by enzyme linked immunosorbent assay in 57 CO patients without EH (pure CO group) and 67 CO complicated EH patients (CO + EH group) ,and 56 healthy subjects (normal control group) .Blood glucose ,blood lipid and biochemical indexes were compared and analyzed among three groups ,and Logistic multi - factor gradual regression analysis was used to perform risk factor analysis .Results : Serum omentin - 1 level in CO + EH group was significantly lower than those of pure CO group and normal control group [ (25.15 ± 3.95) ng/ml vs .(45.63 ± 9.66) ng/ml ,(53.12 ± 7.97) ng/ml , P < 0.05 or < 0.01] ,but there was no significant difference between pure CO and normal control group , P > 0.05 ;Logistic multi - factor gradual regression analysis indicated that age and homeostasis model - insulin resistance index (HOMA - IR ) were independent risk factors affecting EH occurrence in obese people (OR = 1.124 ,95% CI : 1.000 - 1.248 ,P = 0.049 ;OR = 3.446 ,95% CI : 1.087 - 5.607 ,P = 0.001) ,while serum omentin - 1 level was an independent protective factor (OR = 0.423 ,95% CI : 0.210 - 0.636 , P = 0.001) .Conclusion : Serum omentin - 1 level may possess certain guiding significance in early diagnosis ,prevention and treatment for patients with central obesity complicated essential hypertension .
