Journal of Practical Radiology 2000;0(12):-
Objective To explore the applied value of MRI in diagnosing pyogenic of infection of gluteus muscles.Methods MRI data in 9 cases with pyogenic infection of gluteus muscles proved by operation or biopsy were retrospectively analysed by comparison with the pathological diagnosis.Results The pyogenic infections localized at unilateral gluteus muscles involving single,two or three gluteus muscles in all cases.On MRI,the infective gluteus muscles were swelling diffusely and the infections developed along the long axis of the muscles and most or all gluteus muscles were involved.4 cases appeared as suppurative myositis and 5 cases developed typical abscess.4 cases were accompanied with subcutaneous edema and the abscess broken into skin in one case.Conclusion The pathological characteristics of the stage and extent of the pyogenic infection in gluteus muscles can be displayed by MR imaging.

Objective To introduce a new computer-assisted external frame for osteotomy to correct complex tibial and fibular deformity.Methods From January 2012 to December 2013,15 patients with complex tibial and fibular deformity were treated with a computer-assisted external frame and related computer software for surgical correction.All were unilateral limb deformity,involving the left lower limb in 8 cases and the right lower limb in 7 cases.They were 8 males and 7 females,15 to 43 years of age (average,26.8 years).The deformity was caused by old osteomyelitis in 9 cases and trauma sequela in 6.The related angles,distances and rotations were measured on the postoperative radiographs of the lower limbs.The data were input into the software to calculate the daily adjustment lengths of the frame rods.Daily frame adjustments were conducted according to the data calculated.The frame was removed when expected results were achieved.The patients lived independently during the adjustment.Results The 15 patients were effectively followed up for 10 to 22 months (average,15 months).Frame fixation time averaged 8.4 months (from 5.5 to 13.1 months).The reunion time averaged 8.0 months (from 5.4 to 12.1 months).The hospitalization time averaged 2.4 months (from 2.0 to 2.8 months).In 10 cases of limb shortening,the shortening lengths averaged 0.5 cm (from 0 to 0.9 cm) after adjustment.In 12 cases of angulation deformity,the angulation averaged 3.3° (from 0° to 5.4°) after adjustment.In 5 cases of rotation deformity,the maximum internal rotation was 5° and the maximum external rotation 10° after correction,deviating from the normal values by 3.5° on average.In 6 cases of horizontal displacement,the displacements averaged 0.5 crn after correction.All patients were satisfactory with corrected lower limb alignment,improved symptoms and appearance,giving a subjective satisfaction rate of 100%.Conclusion Use of computer-assisted external frame in surgical correction of tibial and fibular deformity can achieve satisfactory outcomes in simple,accurate,standardized,minimally invasive manners.

Objective: To measure and compare the color of a new and a conventional Vita shade guide(VITAPAN 3D-Master and LUMIN RVACUUM-Farbskala) in order to provide the references for clinical application.Methods: Color in the two shade guides was measured with Minolta colorimeter CR-321 under the light of D 65 and reported in CIE1976L*a*b* color system. Each tab was detected 3 times in the same dimensions at the middle facial surface. Mean values were calculated as the shade of the tab.Results: The range of color value in VITAPAN 3D-Master was larger than that in LUMIN R VACUUM-Farbaskala because the lower value tab was added. The distrbution of a* deviated to the red color , while the green color was relatively deficient. The yellow color could cover the color space of Chinese teeth, and the blue was not enough, although the distribution of b* was enlarged. The tabs of the two shade guides did not match with each other. Only a few tabs could not tell in shade by naked eyes. Conclusion: VITAPAN 3D -Master shade guide can not cover the color of Chinese teeth although it has 10 tabs added and color space enlarged.

Objective: To develop a new denture grinding machine to replace the manually grinding procedure for metallic denture parts. Methods: Two hexagonal barrels were symmetrically fixed on a round plate. The direction of rotation and revolution of the barrels were reversed. The denture parts that were put into the barrels together with grinding materials and solution were ground by centrifugal force caused by rotation and revolution of the barrels. Results: The surface roughness of pure titanium castings went down from 1.060 ?m to 0.3113 ?m after ground with the automatic grinding machine using different shapes of grinding materials in series. Conclusion: The automatic grinding machine is competent for grinding the metallic denture parts.

Objective: To study the effects of percutaneous coronary intervention (PCI) on blood levels of vascular endothelial growth factor (VEGF), high sensitivity C-reaction protein (hs-CRP) and fibrinogen (Fg) in patients with acute myocardial infarction (AMI).
Methods: Our research included 2 groups: AMI group,n=110 patients with PCI and Control group,n=53 healthy subjects from physical examination. Blood levels of VEGF, hs-CRP and Fg were compared between pre-operation and 30 min, 24 h, 72 h post-operation; the peak values of VEGF, hs-CRP and Fg were compared between the patients with post-operative MACE occurrence at 24 h and the patients without MACE occurrence.
Results:①Compared with Control group, blood levels of VEGF, hs-CRP and Fg in AMI group were increased at pre-operation and 30 min, 24 h, 72 h post-operation, for VEGF (pg/ml) as (84.7±21.4) vs (130.5±40.2) and (143.2±49.7), (107.1±31.8), (97.3±24.4); for hs-CRP (mg/L) as (1.03±0.34) vs (3.11±0.56) and (4.67±0.62), (6.42±0.72), (2.83±0.56); for Fg (mg/L) as (3.86±0.32) vs (4.79±0.52) and (5.02±0.54), (5.54±0.67), (4.11±0.44) respectively, allP<0.05. In AMI group, the post-operative value of VEGF was ifrst increased, it reached the peak at 30 min and then gradually decreasing; while hs-CRP and Fg were increased gradually, they reached the peak values at 24h time point, allP<0.05.②In AMI group, compared with the patients without post-operative MACE (72/110), the patients with MACE (38) had elevated 24h post-operative levels of VEGF as (131.7±36.5 vs 155.5±42.8), hs-CRP as (5.68±0.62 vs 6.89±0.53) and Fg as (5.23±0.60 vs 5.66±0.55) respectively, all P<0.01.
Conclusion: Post-operative monitoring of blood levels of VEGF, hs-CRP and Fg had the important clinical value in AMI patients after PCI.

Objective To explore the level of polyunsaturated fatty acids (PUFAs) in blood plasma and its relation with the behavior ofchildren with autism. Methods High performance liquid chromatography was used to measure the level of free PUFAs of blood plasma in30 autistic children and 20 healthy children. Conner's Parent Rating Scale (parents) and the Repetitive Behavior Scale-Revised (RBS-R) RatingScale were used to evaluate the behavior of the children, and the relationship between the PUFAs level and abnormal behavior in the childrenwas also analyzed. Results The level of α-linolenic acid (ALA), docosahexenoic acid (DHA) and total n-3 PUFAs were lower in autisticchildren than in healthy children (P<0.05), especially lower in DHA (P<0.01). There was no significant difference in n-3 PUFAs betweentwo groups (P>0.05); There were negatively correlations between the level of DHA and total n-3 PUFAs in blood plasma and impulsion-hyperactivity,hyperactivity index, learning, anxiety, stereotypic behavior, self-injurious behavior, compulsions, ritualistic behavior and samenessbehavior. Conclusion The level of n-3 PUFAs in blood plasma of autistic children was lower than the healthy children and the level ofPUFAs were correlated with the behavior of autistic children.
