ObJective To measure the level of MDA and SOD in cerebrospinal fluid from patients with cysticercosis indifferent stages and to investigate their effects on this dieases. Methods Forty-nine patients with a single cysticercus incerebral parenchyma and twenty normal controls parlticipated in the study. According to the magnetic resonance imaging(MRI) results, patients were divided into four stages. The level of MDA,SOD in CSF were tested. The data were analyzedwith the software of SPSS. Results The amount of SOD was significantly decreased in all stages except the fourth stage,while the level of MDA was increased in all the stages,and reached its peak in the second stage. There was a negative cor-relation between SOD and MDA. Conclusion The data suggested oxygen free radicals may be a main mechanism of para-site killing.

Objective To investigate the elasticity of the radial artery wall in type 2 diabetes mellitus (T2DM) patients with elastosonography. Methods A total of 37 patients with T2DM and 42 normal subjects were studied with elastosonography. The systolic diameter (Ds) and diastolic diameter (Dd) of the radial artery were measured, and the strain ratio of the blood in the radial artery to the wall of the radial artery was calculated. Results The strain ratio of the radial artery in T2DM group was significantly higher than that in normal group (P＜0.05). There was no significant difference in Ds and Dd of the radial artery between T2DM group and the control group (P＞0.05). Conclusion The early change of the radial artery wall elasticity in patients with T2DM can be assessed with elastosonography.

Objective To evaluate left atrial(LA) function in patients with prophase type 2 diabetes mellitus(T2DM) combinated with or without hypertension using left atrial volume tracking method(LAVT). Methods Thirty-one simple T2DM(T2DMI group) ,21 T2DM accompany with hypertension(T2DM2 group) and forty-five healthy subjects (control group) were enrolled in this study. Ultrasound LAVT(EUB-6500, Hitachi Medical Corporation) was applied to display and analyzed the LA volume loop imaging on the standard LV apical two and four chamber views. The maximal and the minimal LA volume (LAVmax, LAVmin) and the volume before LA contraction (LAVp) were recorded from the LA volume loop. The body surface area was used to correct these volume indexs. The LA reservoir function was assessed by calculating the total of LA filling volume (LAVItotal) and the expansion index(iLAVIe). The passive and active emptying percentage of the total emptying volume(LAVIpass, LAVIact) and the emptying index(iLAVIpass,iLAVIact) were caculated as the parameters of the LA conduit and booster pump function. Results Compared with the values in the control group, the LAVhotal,LAVIact were significantly higher and the LAVlpass,iLAVlpass were lower in the T2DM group (all P<0.05) ,while the iLAVIact was higher only seen in the T2DM2 group(P<0. 05). The LAVlact, iLAVIact were higher and the LAVIpass was lower in T2DM2 group than those in the T2DM1 group (all P<0.05). Conclusions The LA conduit hypofunction in primary in the prophase T2DM,when combinated with hypertension the LA constriction function compensatorily increased, LAVT can evaluate the function of LA in patients with T2DM accurately and rapidly.

Objective To observe the rotation of subendocardium and subepidium by two-dimensional speckle tracking imaging(2D-STI),and to evaluate its performance in diastolic heart failure patients(DHF)with a normal left ventricular ejection fraction. MethodsNinety-seven consecutive clinically stable patients were enrolled in this study [41 healthy controls,36 with diastolic heart failure,20 with systolic heart failure (SHF)]. High frame rate dynamic two-dimensional images were recorded at the left ventricular short-axis view,including basal, papillary muscle and apical planes. Subendocardial and subepicardial global rotation were measured using Q-lab 7.0 software offline. Results ① In all the subjects, the rotation of the subendocardium was obviously greater than that of subepicardium. ②As seen from the apex,left ventricular subendocardium and subepicardium performed a wringing motion with a clockwise rotation at the base and countclockwise rotation at the apex. ③In the apical plane, subendocardial rotation was significantly lower in both heart failure groups than in controls,and was depressed to a larger extent in SHF patients than in those with DHF. Subepicardial rotation was no significant difference between the DHF group and the control group, though it was significantly lower in patients with SHF. ④At the base, the rotation of subendocardium and subepicardium were not different between DHF and control groups, but it was significantly reduced in patients with SHF. Conclusions The subendocardial rotation is reduced, but subepicardial rotation is normal in DHF patients. On the other hand, in patients with SHF, subendocardial and subepicardial rotation are both reduced. The left ventricular systolic properties are impaired in DHF patients.

Objective:To study the clinical characteristics and compliance of early-onset gout patients by case-control analysis.Methods:A total of 111 early-onset patients (onset age ≤35 years old) were included as Group A, and 111 non-early-onset patients (onset age >35 years old) with matched disease durationwere included as Group B. The differences ofclinical characteristics, causes of acute gout attack, dairy diet habits, compliance, and misunderstanding of the disease were compared.Results:Compared with the non-early-onsetgoutpatients, the early-onset patients had a higher proportion of obesity (63 cases vs 28 cases), family history (36 cases vs 20 cases) and tophus (39 cases vs 23 cases) and higher level of VAS scores (8.5±1.3 vs 7.6±1.7; χ2=22.988, P<0.01; χ2=5.749, P=0.016; χ2=5.729, P=0.017; t=4.639, P<0.01), lowerproportionof the first metatarsophalangeal joint involvement as the initial joint involvement (45.9%, 51 cases vs 59.4%, 66 cases; χ2=4.066, P=0.044), higher proportion of the ankle involvement as the initial joint involvement (34.2%, 38 cases vs 21.6%, 24 cases; χ2=4.386, P=0.036), higher proportion of alcohol drinkers and high fructose drinkers, which was more likely to relate to alcohol intake, strenuous exercise and high fructose intakeas trigger of the flare ( χ2=6.513, P=0.011; χ2=7.126, P=0.008; χ2=1.978, P=0.160), while the proportion of regular exercisers and on diet in the family was lower ( χ2=22.887, P<0.01; t=-4.917, P<0.01). The proportion of poor diet and medication compliance in Group A was higher than that in Group B(57.7%, 64 cases vs 38.7%, 43 cases; χ2=5.207, P=0.022; χ2=5.867, P=0.015). As for the reason for poor treatment compliance, early-onset gout patients were more worry about the side-effects of drugs than non-early onset patients ( χ2=4.190, P=0.041). There was no significant difference between the two groups in the main misunderstanding of gout. Conclusion:Although early onset gout patients are young, their condition is more serious, and compliance is poorer, this group of patients should be highly valued in clinical diagnosis and treatment.
