Objective To analyze the pregnancy outcomes and effect on fertility in women with Graves' disease after 131I therapy and the health status of their newborns.Methods From year 2009 to 2012,a total of 102 female patients with Graves' disease,who were pregnant during propylthiouracil (PTU)/L-thyroxine (euthyrox) maintenance treatment,were retrospectively recruited.The subjects were divided into 131I therapy group (n=57) and non-131I therapy group (n=45).The time interval between 131I (non-131I) therapy and getting pregnant were at least 6 months.They were followed for their pregnancy outcomes.During the pregnancy period,recorded parameters included serum thyroid biochemistry,dose of PTU/euthyrox,health conditions of the newborns and termination of pregnancy.Medication compliance,delivery mode,baby gender and body weight between the 2 groups were compared byx2 test,Mann-Whitney u test,Fisher exact test and two-sample t test.Results Ninety-seven patients had normal labor.In 131I therapy group and non-131I therapy group,15 vs 22 patients were treated by PTU,31 vs 18 by euthyrox and 11 vs 5 without any medication during pregnancy (x2=5.69,P＞0.05).The medical compliance (PTU and euthyrox: u=163.50,233.50,both P＞0.05) was similar between the 2 groups.The delivery mode (natural labor/cesarean: 36/19 vs 28/14,x2 =0.016),baby gender (male/female: 32/23 vs 18/24,x2 =2.239) and body weight ((3.18t0.47) vs (3.07±4.17) kg,t=1.154) were also similar between the 2 groups (all P＞0.05).Condusion Women of reproductive age with Graves' disease were found to have normal pregnancy after 131I therapy,on the condition that their thyroid function could be reasonably controlled and maintained by the proper medication before and during pregnancy.

Objective To analyze the MR imaging features of pyocephalus. Methods MR imaging features!of pyocephalus in 5 cases with clinically proved were analyzed retrospectively. All patients were undergone no-contrast MR imaging. 3 patients received diffusion weighted-imaging(DWI). Results In all five patients,the debris and pus with pus-fluid level were shown inside the lateral ventricle.The debris or pus was slightly hyperintense on T1WI, slightly hypointense on T2WI relative to cerebrospinal fulid(CSF). On DWI, the debris was hyperintense in 1 case and isointense in 2 cases.Conclusion The features of MR imaging of pyocephalus is specific. MR imaging is valuable in the diagnosis of pyocephalus.

BACKGROUND:Bone morphogenetic proteins are associated with the formation and development of scars. Fibroblasts are closely related to the proliferation and maturation of scars. However, the expression of bone morphogenetic proteins in fibroblasts in different stage of hypertrophic scars remains poorly understood.
OBJECTIVE:To observe the expression of bone morphogenetic protein 2/4, bone morphogenetic protein 7, bone morphogenetic protein receptor IA in fibroblasts in different stage of hypertrophic scars.
METHODS:The immunohistochemical SP method was employed to detect the expression of bone morphogenetic protein 2/4, bone morphogenetic protein 7, bone morphogenetic protein receptor IA in fibroblasts in 20 cases of proliferative stage hypertrophic scar and 20 cases of maturation stage hypertrophic scar. Al samples were obtained from the Department of Plastic and Aesthetic Surgery, the People’s Hospital of Guangxi Zhuang Autonomous Region, China.
RESULTS AND CONCLUSION:The expression of bone morphogenetic protein 2/4 in fibroblasts in proliferative hypertrophic scars significantly elevated compared with mature hypertrophic scars (P<0.05). In various stages of hypertrophic scars, the expression of bone morphogenetic protein 7 and bone morphogenetic protein receptor IA in fibroblasts was not obviously different (P>0.05). Results demonstrated that bone morphogenetic protein 2/4 expression down-regulated during the development from proliferative stage to maturation stages in fibroblasts in hypertrophic scars. However, there was no change in the expression of bone morphogenetic protein 7 and bone morphogenetic protein receptor IA.

Objective:To detect the expression of miR-106b~25 cluster in glioma cell line and tissues. Methods:Real-time PCR was performed to determine the expression of miR-106b~25 cluster members (miR-106b, miR-93, and miR-25) in different human glio-blastoma cell lines. Different pathological grade glioma specimens were surgically removed. In-situ hybridization was performed to de-tect the expression of miR-106b~25 cluster members in different pathological levels of glioma tissues. Results:In the expression of the benchmark on normal brain tissues, three kinds of miRNAs in all test cell lines have a tendency to increase. Based on the expression of the pathological level I average rate in 43 cases of glioma specimens collected after neurosurgical operations, the real-time PCR results showed that the average expression quantity of the three kinds of miRNAs in each group gradually increase. The increase in tumor path-ological levels results in statistically significant expression differences of miR-106b and miR-93 between the groups (F=4.479, P=0.018 and F=3.493, P=0.040, respectively). However, miR-25 expression differences between the groups have no statistically signifi-cant differences (F=2.766, P=0.075). In situ hybridization results show that the expressions of three miRNAs in high grade gliomas are significantly higher than that in the low-level tumor. Spearman rank correlation analysis results indicate that the expression of these miRNAs signal-intensity distribution is positively correlated with glioma, in accordance with WHO pathology classification. The corre-lation coefficient for miR-106b, miR-93, and miR-25 are 0.617, 0.438, and 0.463, respectively (P<0.001). Conclusion:The expression of miR-106b~25 cluster members is up-regulated in the glioma and is positively correlated with tumor grade.
