Objective:To investigate the effects of trimetazidine on cardiac systolic and diastolic function in patients with chronic congestive heart failure due to coronary artery disease.Methods:45 patients with chronic congestive heart failure due to coronary artery disease were divided into two groups,23 patients in trimetazidine group and 22 in placebo-control group.The echocardiogram indices of cardiac function of patients in two groups-SV,CO,CI,LVEF,VA,VE and VA/VE were measured before and after treatment.Results:The indexes SV,CO,CI and LVEF were significantly higher in trimetazidine group than those in control group(P0.05).Conclusion:Trimetazidine can improve systolic function of ischemic heart by improving the energy metabolism of ischemic heart.

Objective:To investigate the relationship among serum uric acid,C-reactive protein and the degree of carotid artery atherosclerosis in patients with essential hypetension.Methods:122 patients with essential hypertension were divided into intima-media thickness group(Ⅰ),plaque development group(Ⅱ) and vessel stenosis group(Ⅲ).Concentration of serum uric acid and C-reactive protein were measured in each patient and the relationship between serum uric acid and C-reactive protein was observed.Results:The concentrations of serum uric acid and C-reactive protein in group Ⅱ and Ⅲ were positively connected with pathologic changes of carotid artery atherosclerosis( P

Objective To investigate the impact of different surgical methods and different doses of euthyrox on bone mineral density.Methods A sample of 40 patients received thyroid cancer operation (excised affected side leaf,aisthmus,most of offside and neck VI lymph node dissection)and 40 patients received nodular goiter operation (excised affected side leaf)were collected,the dose of euthyrox taken in was 85 .2μg in thyroid cancer patients and 36.2μg in nodular goiter patients daily,the bone mineral density 6 month and 1 year after operation was detected. Results There was no difference of BMD between the two group 6 month after operation (P>0.05),but BMD of the observation group was (0.64 ±0.28)g/m2,which was lower than that of control group (t=2.235,P=0.03).Com-pared with pre-operation,BMD of control group had no change and the observation group appeared drop 1 year after operation.Conclusion Patients received thyroid cancer taking in euthyrox may show BMD reduced,especial 1 year after operation,doctors should be on the alert and supplement calcium appropriately.

(0.05)).Conclusions PE is an effective form of treatment for recurrent FSGS by removing circulating factor,especially if initiated early.Failure to achieve remissions and maintain stable remission after the initial period of PE imply a poor outcome and glomeruli lesion been sclerosis.Therefore,PE should be performed as early as possible until completely remissions.

A lot of children with congenital heart disease have an abnormal development of nervous system. A variety of biochemical and physical examination indices can be used to predict adverse outcome of neurodevelopment caused by congenital heart disease and they contribute to early intervention and improvement of neurodevelopmental disorders. In recent years, new progresses in the laboratory tests, neurological physiccal examination and perioperative management of the neurodevelopmental abnormalities caused by congenital heart disease have been made. The predictive factors of abnormal neurodevelopment caused by congenital heart disease were reviewed in this article.

BACKGROUND:The creep performance of bone tissues during exercise is achieved through the microstrain,and the holosteous torsion can completely retiect the biomechanicel charactedstics of bone tissues.OBJECTIVE:To determine the creep characteristics of rabbit tibia under the torsion load following exercise.DESIGN,TIME AND SETTING:A parallel controlled animal observational experiment was performed at the Laboratory of Biomechanics in Orthopedic Hospital of Sichuan Province between May 2005 and July 2007.MATERIALS:A total of 32 Japanese white rabbits,irrespective of genders,aged 6 months,were divided into exercise group(n=24)and control group(n=8).METHODS:Exercise group animals were placed in cage to receive electrical stimulus.0.1-0.2seconds once every 20 seconds.Following the stimulation,the animals ran and jumped for several paces along with the cage and made a tum,15 minutes once,three times per day,totally 45 minutes,at the interval of 15 minutes.The exercise was carried out five days per week for 4successive weeks.The control group was fed as exercise group.but received no exercise.MAIN OUTCOME MEASURES:After 4 week exercise.the tibias were griped by the torsion clamping apparatus,the creep characterizes of anterior,posterior,medial and lateral sides of tibia under 0.52 N·m torsion load within 500 seconds were determined by strain gauge technique.RESULTS:Under torsion load,the creeps were present obviously in the rabbit tibia,reached the creep curve inflection point at 2seconds,and then gradually appeared.After 4 weeks,the creeps of tibias at anterior and posterior side in the exercise group were less than control group;in the control group,the anterior side of tibia was remarkably greater than the medial side.After exercise.the creep was the smallest in anterior side,which was less than the lateral side(P＜0.05).CONCLUSlON:The creep characteristics of tibia are anisotropic,the deformation at the anterior and posterior sides is greater than that at the medial and lateral sides.Exercisecan alter the creep charactedstice of rabbit tibia and reduces the creep at the anterior and posterior sides.
