Objective To investigate MRI signal features and MRI appearances of patients with advanced stage in polyacrylamide hydrophilic gel injection for facial plasty.Methods In this study,MRI of 11 cases with 23 polyacrylamide hydrophilic gel injection of facial plasty for 6 to 10 years were retrospectively reviewed.All images were acquired with GE 3.0T MR imaging unit.MR sequences,including FSE T1WI,FSE FS T2WI,and STIR were applied with 8-channel brain coil.MRIs sliced through the maxillofacial region in the transverse,coronal and sagittal planes.Results In 11 cases of 23 polyacrylamide hydrophilic gel injection,there were different degrees of capsule rupture and induration in 6 polyacrylamide hydrophilic gel injection,and the images showed sporadic callosities such as subcutaneous nodules and nodules in glands or muscles ; hydrogel migration in 8 polyacrylamide hydrophilic gel injection.Secondary deformity occured in 80 ％ cases,in which the most cases were induced by hydrogel migration.Conclusions Magnetic resonance imaging can make clear of the type of rupture and the distribution leakage of polyacrylamide hydrophilic gel for facial plasty and it is an ideal approach for advanced patients with polyacrylamide hydrophilic gel injection for follow-up.

Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Methods Through a retrospective survey method, 115 stroke patients, based on different treatment methods, were divided into 3 groups:Xuesaitong group (A), carthamin yellow group (B), and Xueshuantong group (C). An analysis on pharmacoeconomic cost-effect was conducted. Results The costs of three therapeutic schemes were 1030.4 yuan, 1876 yuan, and 1545.6 yuan, respectively. The total effective rates of stroke patients in groups A, B and C were 85.37%, 88.57% and 90.04%, respectively. The cost-effect ratios of groups A, B and C were 12.07, 21.18, and 17.17. The added cost-effect ratios of groups B and C compared with group A were 264.25 and 110.32, respectively. Conclusion Xueshuantong Injection has more pharmacoeconomic advantage than Xuesaitong and carthamin yellow Injections in treating stroke.

Objective To investigate the probable pathologic basis of amido proton transfer(APT) imaging by analysing APT signal intensity and pathologic features of different grades of glioma.Methods Twenty-eight patients with glioma confirmed by postoperative pathology underwent APT scan.All the patients were divided into two groups,including 11 cases in low grade (WHO Ⅰ and Ⅱ) and 17 cases in high grade (WHO Ⅲ and Ⅳ) group.The APT rate of tumor core was measured.The specimens were processed with routine hematoxylin-eosin (HE) staining and immunohistochemistry of Ki-67 and CD34.Independent-samples t test was used to detect the difference of APT rate,cellularity,microvessel density and Ki-67 labeling indices of tumor core between low grade and high grade group.Pearson correlation analysis and multi-variable linear regression analysis were used to detect the relationship of APT rate with cellularity,microvessel density and Ki-67 labeling indices of the tumor core.Results The APT rate,cellularity and proliferation index were (2.3±0.6) ％,(9.4±2.4) ％ and (14.2±5.4) ％ in low grade group,while (3.6±0.7) ％,(18.4±4.7) ％ and (31.7±4.5) ％ in high grade group,respectively.Microvessel density was (19.0±7.4) per high-power field in low grade group and (38.9±11.3) in high grade group.There were statistical differences of the APT rate,cellularity,microvessel density and proliferation index between the low grade group and the high grade group (t=-4.94,-5.89,-5.13,and-9.28,respectively,P＜0.01).The APT rate was positive correlated with cellularity,microvessel density and proliferation index.The coefficient of correlation were 0.904,0.598,and 0.750,respectively,(P＜0.01).Multiple linear correlative analysis showed that increasing cellularity (X1),microvessel density (X2) and proliferation index (X3) were the main factors for increasing APT rate,and the correlation equation was Y=0.801 + 0.12X1-0.003X2 + 0.026X3 (F=46.437,P＜0.01,R2=0.853).Conclusions The APT signal intensity of the tumor core could reflect the pathologic features of glioma.The APT rate was positive correlated with cellularity,microvessel density and proliferation index,which indicate the higher APT rate the higher grade tumor.
