Objective Toinvestigatetheclinicalfeaturesandsurgicalprognosisofmoyamoya syndromeinchildren.Methods Theclinicaldataof12childrenwithmoyamoyasyndromeadmittedto the 307th Hospital of People′s Liberation Army from December 2002 to October 2013 were analyzed retrospectively. Eleven of them underwent encephalo-duro-arterio-synangiosis (EDAS). A total of 550 children with moyamoya disease in the same period were used as a control group. The clinical characteristics and surgical efficacy of the children with moyamoya syndrome were summarized and concluded by comparing the clinical data of the two groups,including sex,age of onset,initial symptom,progress symptoms, Suzukiinstallments,imagingfeatures,andsurgicalefficacy.Results Themaleandfemaleratioof the children with moyamoya syndrome was 1∶2. Their mean age of onset was 12 ± 5 years old. There were significant differences in the initial symptom (cerebral infarction and cerebral hemorrhage )and disease progress between the children with moyamoya syndrome group and the control group (5/12 vs. 14. 5%[80/550], 3/12 vs. 61. 8%[340/550],and 5/12 vs. 8.7%[48/550],respectively;all P<0. 05). Within the follow-up period,of the 11 children underwent EDAS,7 cases had no further attack,and 4 cases were improved significantly. There was significant difference in the modified Rankin scale (mRS)between the beforeandaftersurgery(0[0,1]vs.2[1,2];P<0.05).Conclusions Theclinicalfeaturesofthe children with moyamoya syndrome have some differences with those with moyamoya disease. Timely and effective EDAS treatment may effectively prevent disease progression and improve the prognosis of patients.

Objective To investigated the application value in the efficacy evaluation of transcranial Doppler (TCD) in encephalo-duro-arterio-synangiosis (EDAS) for moyamoya disease. Methods The patients with moyamoya disease treated with EDAS conducted digital subtraction angiography (DSA) and TCD examinations before procedure and at 6 months after procedure respectively. The pulsatility index (PI), resistance index (RI) and mean flow velocity (MFV) before and after the superficial temporal artery surgery were measured respectively. The correlation between the TCD parameter variation rate and DSA efficacy grading was evaluated. Using the receiver operator characteristic (ROC) curve to calculate the optimal cut-off value of the TCD parameters for predicting the operation efficacy. Results A total of 46 patients with moyamoya disease were enroled, 40 patients were bilateral hemisphere involvement and 6 were unilateral involvement. A total of 86 hemispheres were treated with EDAS. According to the results of DSA reexaminations, the grades of efficacy were as folows: grade 0, 18 sides, grade 1, 37 sides, grade 2, 18 sides, and grade 3, 13 sides. When the DSA grade was 0, there were no significant differences in PI, RI and MFV before and after procedure, and there were significant differences in the postoperative change of other TCD parameters at al levels (al P < 0. 001). At 6 months after procedure, the change rates of PI, RI and MFV were - 30. 83% ± 21. 71% , - 19. 64% ± 14. 45% and 96. 08% ± 100. 76% , respectively, and they had good correlation with the results of DSA efficacy grading. Their Spearman correlation coefficients were- 0. 879, - 0. 891 and 0. 715, respectively (al P < 0. 001). ROC curve analysis showed that the best cutoff values of the TCD parameter change rates for predicting good operative effect were as folows: PI decrease rate, 36% (area under the curve, 0. 966; sensitivity, 0. 968, specificity, 0. 891; P < 0. 001), RI decrease rate, 27% (area under the curve, 0. 973; sensitivity, 0. 903, specificity, 0. 946; P < 0. 001), and MFV increase rate, 111% (area under the curve, 0. 879; sensitivity, 0. 742, specificity, 0. 927; P < 0. 001). Conclusions TCD can detect hemodynamic parameter changes of superficial temporal arteries after EDAS. It has higher application value in the long-term postoperative efficacy evaluation.

BACKGROUND:The bioceramics has the ideal pore size, high porosity and the through-hole rate, can provide the ideal physiological activity space for the bone cel repair, and can obviously improve bone conduction. OBJECTIVE:To explore the bone conduction and bone induction in the repair of bone defects in the stage of bone defect of bionic biphasic ceramic bioactive bone. METHODS:A total of 20 New Zealand white rabbits were randomly divided into bioactive glass and biomimetic biphasic ceramic bioactive bone groups, and were used to construct the animal bone damage model. They were given the repair with bioactive glass and biomimetic biphasic ceramic bioactive bone. RESULTS AND CONCLUSION:At 4 weeks after model establishment, scanning electron microscopy demonstrated that dense periosteal tissue was observed in the biomimetic biphasic ceramic bioactive bone group. At 8 weeks, dense combination was found, and no obvious fissure existed. At 12 weeks, complete bone demarcation blurred, showing a natural transition. Moreover, the binding site was very dense. There were a large number of new bone tissues, bone trabecula was regular and connected to a piece. The bone material has been largely degraded. Bone defects were repaired completely. The bone density was close to normal bone. At 8 weeks, in the bioactive glass group, the binding site presented obvious fissure. At 12 weeks, the fissure had been connected, but the binding was not tight as compared with the bionic biphasic ceramic biologic active bone group. The bone defect got preliminary repair. A smal number of new bone formed trabecular bone, but could not connect or traverse. There was no recanalization of the marrow cavity. A few continuous bone cal us traversed the broken end. These data demonstrate that bionic biphasic ceramic bioactive bone has good bone conduction, bone induction and biocompatibility in the repair of segmental bone defects.
