Objective To evaluate different measurement methods in histogram for the diffusion and perfusion parameters from intravoxel incoherent motion (IVIM) MR imaging of different types of uterine fibroids.Methods 63 patients with confirmed uterine fibroids (80 in total) were examined with MR imaging.3D T2WI and IVIM imaging were performed for those patients.The fibroids were classified into three types (type 1, 2, 3) on the basis of different signal intensities on T2WI according to Funaki's theory.Real diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f) were calculated using IVIM analysis.25%,50% and 75% of those parameters (D25,D50,D75,D*25,D*50,D*75,f25,f50 and f75) as well as mean values (Dmean,D*mean and fmean) were calculated using histogram method.ANOVA was used to compare the IVIM parameters among the three types of fibroids.Results There were 44 type 1,24 type 2 and 12 type 3 fibroids in the total of 80 fibroids.There was significant difference among all the diffusion parameters from histogram and mean values of different types of fibroids, and only one perfusion parameter D*75 value showed significant difference (P<0.05).There was no significant difference among all the f values from histogram and mean values.Conclusion Different measurements of parameters from IVIM histogram showed no added value for diffusion features in different types of fibroids compared to mean value.While the perfusion parameter D*75 value from histogram can distinguish the features of perfusion within different types of fibroids compared to mean value.

Objective To evaluate the nutritional risk screening for younger patients with stroke and to explore risk factors of malnutrition. Methods Younger patients with stroke were enrolled in a prospective way. The patients were evaluated by nutritional risk screening 2002 (NRS 2002) at their admission for nutritional risk screening, and were divided into nutritional risk group and no nutritional risk group according to the evaluation results. Prealbumin less than 200 mg/L was defined as malnutrition. Demographic and baseline clinical characteristics of the patients were analyzed with multivariate logistic regression analysis to determine independent risk factors for malnutrition at the admission and the 14th day. Results (1) A total of 152 young stroke patients were enrolled, including 51 in nutritional risk group, 101 in no nutritional risk group, the rate of nutritional risk was 33.6%(51/152). (2) The rate of malnutrition at admission was 13.8%(21/152), the rate of malnutrition in nutritional risk group was 25.5%(13/51), and 7.9%(8/101)in no nutritional risk group on admission. While the rate of malnutrition was 32.2%(49/152), including the rate of malnutrition in nutritional risk group was 60.78%(31/51)and 17.8%(18/101)in no nutritional risk group was at the 14th day of admission. (3) Multivariate Logistic regression analysis showed that advanced age (from 36 to 45 years), sex, diabetes, hyperthyroidism were independent risk factors for malnutrition in younger patients with stroke. Recent history of surgery and smoking, stroke-associated pneumonia, post-stroke depression, swallowing disorder, sleep disorder, moderate and severe neurologic deficits were also risk factors for malnutrition. Conclusion The incidence of malnutrition in youngerpatients with stroke were higher, and earlier nutritional risk screening and nutritional support in these patients were urgent.

Objective To observe the efficacy and safety of rosuvastatin in the treatment of hyperlipidemia and carotid atherosclerotic plaque in young ischemic stroke patients.Methods In prospective study,264 young ischemic stroke patients with hyperlipidemia and carotid atherosclerotic plaque were randomly divided into low dose group,middle dose group,high dose group,88 cases in each group.All patients were given rosuvastatin immediately after dinner,in doses of 5mg,10mg,20mg,respectively,for eight months.Then,the changes of hyperlipidemia and carotid atherosclerotic plaque in the three groups were surveyed,and its safety by the observation of clinical symptoms and monitoring of adverse reactions after eight months were assessed.Results Before treatment,the blood fat and carotid atherosclerosis plaque index in the three groups had no statistically significant differences (all P >0.05). After treatment,the total cholesterol,triglycerides,low -density lipoprotein cholesterol of the high dose group were (1.67 ±0.68)mmol/L,(3.23 ±0.53)mmol/L,(1.83 ±0.62)mmol/L,which of the middle dose group were (1.93 ±0.74)mmol/L,(3.73 ±0.23)mmol/L,(2.24 ±0.73)mmol/L,which of the low dose group were (2.16 ± 0.77)mmol/L,(4.06 ±0.93)mmol/L,(2.93 ±0.35)mmol/L.These indicators were decreased than before treat-ment [(2.79 ±0.72)mmol/L,(5.40 ±0.67)mmol/L,(3.64 ±1.03)mmol/L,(2.75 ±0.81)mmol/L,(5.59 ± 0.95)mmol/L,(3.43 ±0.92)mmol/L and (2.83 ±0.53)mmol/L,(5.84 ±0.79)mmol/L,(3.83 ±0.88)mmol/L].The decrease of the high dose group was higher than the middle and low dose group,the difference was statistically significant(F =6.61,P <0.05).The effective rate of the high dose group was 85.23%.which of the middle dose group was 76.14%.The effective rate of the low dose group was 62.50%.The efficacy of the high dose group was better than the middle dose group and low dose group,the difference was statistically significant(χ2 =5.79,P <0.05).After treatment,the intima -media thickness,plaque area and Crouse score of the high dose group were (0.92 ±0.41)mm,(0.52 ±0.56 )mm,(3.07 ±0.58 )mm,which of the middle dose group were (1.11 ± 0.52)mm,(0.60 ±0.36)mm,(3.39 ±0.83)mm,which of the low dose group were (1.42 ±0.87)mm,(0.81 ± 0.91)mm,(4.09 ±0.77)mm,which were decreased than before treatment[(1.71 ±0.89)mm,(0.86 ±0.55)mm, (4.39 ±0.19)mm,(1.74 ±1.03)mm,(0.89 ±0.48)mm,(4.42 ±0.53)mm and (1.68 ±0.96)mm,(0.87 ± 0.61)mm,(4.38 ±0.22)mm].The decrease of the high dose group was higher than the middle and low dose group, the difference was statistically significant (F =5.83,P <0.05 ).The effective rate of the high dose group was 78.41%.The effective rate of the middle dose group was 52.27%.The effective rate of the low dose group was 30.68%.The efficacy of the high dose group was better than the middle dose group and low dose group,the difference was statistically significant(χ2 =5.37,P <0.05).There were 10 cases (11.36%)had adverse reaction in the low dose group,12 cases (13.64%)in the middle dose group,14 cases (15.91%)in the high dose group.There was no statistically significant difference in incidence of adverse reactions among the three groups (P >0.05),and no serious adverse reaction was found.Conclusion The high dose rosuvastatin treatment can reverse the nature of plaque, decrease the thickness of the plaques and lower blood lipid of young ischemic stroke with hyperlipidemia and carotid atherosclerotic plaque,which is better than middle and low dose,and has better security.There is no serious adverse reaction.It is worth for clinical promotion.
