Objective To evaluate the effect of three diamension-digital subtraction angiography (3D-DSA) or computed tomography angiography (CTA) on the patients with ruptured multiple intmcranial aneurysm (MIA). Methods A retrospective study on 21 patients with MIA was performed.After scanning with 3D-DSA or 3D-CTA, three-dimensional reconstruction of MIA was carried out by 3D workstation,then the diagnosis was decided and the treatment plan (endovascular treatment or microsurgery) was selected according to stereoscopic image of MIA. Results (1) 3D-DSA or CTA was performed in 21 patients with subarachnoid hemorrhage (SAH),it was revealed these patients carried with 48 aneurysms,including 35 small aneurysms (25 mm).Not only miero-aneurysms and small aneurysms could be precisely showed,also the size of aneurysmal neck,the relationship of the aneurysm and the parent vessel and contiguous branches by stereoscopic image.(2) According to the standard of classification,9 patients with MIA for gradeⅠ(42.9%),10 for gradeⅡ(47.6%),2 for gradeⅢ(9.5%),0 for gradeⅣ.Endovascular treatment was selected prior to microsargery for those high grade patients.In this group,17 patients with 40 aneurysms underwent endovascular embolotherapy with GDC coils.Twenty four anemysms were completely occlusioned,12 beyond 90%,4 were left without treatment because of their small size.In microsurgery group,3 aneurysrus were totally clipped,1 could not be found during operation.No any treatment was accepted in 2 patients with 4 aneurysms. Conclusions 3D-DSA or CTA,which is very useful for the diagnosis and treatment of MIA,could improve the accuracy of diagnosis of MIA and clearly show the stereoscopic image of MIA,also the relation of sac and parent artery.For those patients with high grade MIA,endovascular treatment was selected prior to microsurgery,pro re nata,used to combine with mierosurgery.

Objective To investigate the value and dynamic characteristics of diffusion-weighted imaging(DWI)in rabbit liver VX_2 tumor model,with correlation of pathology.Methods Forty New Zealand rabbits were included in the study and VX_2 tumor piece was implanted directly into the liver after laporotomy.Fiffteen had two intrahepatic implants while twenty-five had one implant.DWI was performed on the seventh,fourteenth and twenty-first day after implantation,while routine T_1WI and T_2WI sequences were done on the seventh and fourteenth day.Ten VX_2 tumor samples were studied by pathology.Results The lump detection rates on the seventh day after implantation of DWI,T_1WI and T_2WI were 78.7%(37/47), 10.7%(3/28)and 53.6%(15/28)respectively with statistical significance(x~2=32.61,P

0.05).Conclusions The potential of VX_2 tumor infiltration and metastasis will decrease after chemoembolization in the long-run,while the proliferation ability will increase within a short period of time. The ADC may reflect the proliferation of VX_2 tumor cells.

OBJECTIVETo evaluate the safety and efficacy of imatinib in treatment of chronic myeloid leukemia (CML) patients.

METHODSFrom December 2003 to March 2007, 151 patients entered Glivec International Patient Assistance Program (GIPAP) in our center and received imatinib therapy. The overall and progression free survival, hematologic, cytogenetic and molecular response, and adverse events were evaluated. The factors associated with outcome of imatinib therapy were also analysed.

RESULTSOne hundred and forty-two patients were evaluable with a median follow-up duration of 21.5 (6 -78) months. (1) The rate of cumulative complete hematologic response (CHR), major cytogenetic response (MCyR), complete cytogenetic response (CCyR) and complete molecular response (CMoR) in chronic phase (CP) CML patients were 96.9%, 82.6%, 76.1% and 29.4%, respectively. These rates were significantly higher in patients with CP than in those with accelerated phase (AP) and blast crisis (BC) (P < 0.0001). (2) The overall survival (OS) rates at 1, 2 and 3 year were 100%, (97.3 +/- 1.9)% and (95.8 +/- 2.4)% for CP patients, they were (84.7 +/- 8.2)%, (77.0 +/- 10.4)% and (69.3 +/- 11.9)% for AP patients, and (62.9 +/- 8.9)%, (41.9 +/- 9.2)% and (28.5 +/- 9.1)% for BC patients, respectively (P < 0.0001). The progression-free survival (PFS) rates at 1, 2 and 3 year were (98.9 +/- 1.1)%, (93.9 +/- 2.7)%, (93.9 +/- 2.7)% for CP patients, (68.9 +/- 10.6)%, (61.3 +/- 11.9)%, (61.3 +/- 11.9)% for AP patients, (36.4 +/- 8.8)%, (25.4 +/- 8.1)%, (10.1 +/- 8.2)% (P < 0.0001) for BC patients respectively. (3) Among 92 CP patients, the rates of MCyR and CCyR in newly diagnosed patients were significantly higher than those in interferon therapy failure patients (P = 0.015, P = 0.010). Patients obtained CCyR at 12 months after the initiation of imatinib treatment were associated with longer PFS (P = 0.0099). According to the Sokal scoring system, the rates of MCyR and CCyR in low-risk patients were significantly higher than those in intermediate-risk and high-risk patients (P = 0.0013, P = 0.0024). Sokal score was also significantly associated with disease progression (P = 0.0467). (4) The adverse events of imatinib were moderate and tolerable.

CONCLUSIONSTreatment of CML patients in CP with imatinib can induce high hematologic, cytogenetic and molecular response and overall survival, but can not do satisfactorily for patients in AP and BC.

OBJECTIVETo evaluate the early diagnostic significance of diffusion weighted imaging (DWI) compared with conventional magnetic resonance imaging (MRI) and to find the dynamic pattern of DWI and conventional MRI in newborn infants with neonatal cerebral infarction (NCI).

METHODSThe imaging studies and clinical records of six newborn infants with NCI admitted to our ward between April 2004 and October 2005 were reviewed. All examinations were performed on a 3.0-T MRI system (Philips Intera Acheva Magnetom Vision) with echo-planar imaging capability with the use of a standard protocol. The imaging protocol for all the patients contained diffuse weighted images (EPI-SE, TR = 2144 ms, TE = 56 ms), T(1)-weighted images (TR = 389 ms; TE = 15 ms; slice thickness = 4 mm) as well as T(2)-weighted images (TR = 3035 ms; TE = 100 ms; slice thickness = 4 mm). Except the magnetic resonance image examination mentioned above, the following examinations were performed in all patients: whole blood cells count, serum total calcium and ionized calcium, blood glucose, C-reactive protein (CRP), blood culture, prothrombin time and partial thromboplastin time, chest radiograph (CR), cardiac color Doppler, conventional MRI and DWI of brain.

RESULTSAll the patients were full term infants. One had severe asphyxia and the other five had neither intrauterine distress nor birth asphyxia. Five of the patients had no localized neurological signs in the early course except for abnormal muscular tone to some extent, but just seizure as their major symptom. A seizure episode was the most common sign and no other positive signs of nervous system was found in the newborn with NCI. All the patients had normal white blood cells, red blood cells, blood platelet, blood glucose, serum total calcium and ionized calcium, prothrombin time and partial thromboplastin time, CRP and cardiac color Doppler. The first MRI was performed from 18 hours to 4 days after the onset of illness when four patients showed abnormal findings on routine MRI (T(1)WI hypointensity, T(2)WI hyperintensity) and the other two showed normal results while all the six showed abnormal hyperintensty on DMI. On following up, all the patients showed T(1)WI hypointensity and T(2)WI hyperintensity on routine MRI while hypointensity was shown on DWI. There were cortical and subcortical white matter damage with obvious high signal intensity on DWI in left temporal lobe and parietal-occipital lobes of 4 cases and in left frontal-parietal lobes of one patient and in left basal ganglia of another patient, but lesions of hypointensity on T(1)W and hyperintensity on T(2)W in only 3 patients between 2nd day and 3rd day after onset; two weeks later there were the lesions of hypointensity on T(1)W and on DWI and hyperintensity on T(2)W seen in all patients in the areas similar to those found before on DWI. Lesions of hypointensity on T(1)W and DWI and of hyperintensity on T(2)W remained in two patients at sixth month and in one patients at 15th month.

CONCLUSIONSeizure was the most common sign of newborn infants with NCI and seizures in the neonatal period may be the single symptom of acute ischemic cerebral infarction. It was difficult to establish the diagnosis in the acute phase by the use of ultrasound, CT, and conventional MRI because of the high water content of the immature brain.. DWI seems to be a sensitive early diagnostic measure for NCI. Hyperintensity was shown on DWI at the early stage of the disease. Two weeks later, the hyperintensity turned to hypointensity and lasted long with the same signal characters and lesions on T(1)WI. The lesions of hypointensity on T(1)W and DWI and hyperintensity on T(2)W appeared at 2 weeks and remained for more than 1 year. T(2)-weighted sequences should supplement DW images to reliably detect subacute ischemic infarctions in the neonatal period.

OBJECTIVETo distinguish lingual thyroglossal duct cyst (LTDC) from laryngomalacia in newborn infants.

METHODSData of 10 newborn infants with laryngeal stridor and dyspnea, admitted to the department of neonatology in our hospital during December, 2004 to August, 2007, who were finally diagnosed with LTDC though previously diagnosed as congenital laryngeal stridor in other hospitals, were summarized and analyzed.

RESULTSInspiratory stridor with chest wall retractions was cardinal symptom of newborn with LTDC. A slightly gray and round cyst with smooth surface at the base of the tongue was found with laryngoscopy. On computed tomography examination of larynx, a well-circumscribed lesion with low intensity was detected at the base of the tongue protruding into the air passage. Pathological examination demonstrated that the cyst wall was composed of tabular and columnar epithelium.

CONCLUSIONSLTDC is a common disease in newborns, which is similar to laryngomalacia. For neonates suspected of LTDC, laryngoscopic examination should be performed first, while laryngeal CT scan is an important diagnostic basis. Cyst puncture can ameliorate the symptoms of the patients, while surgical removal is the method of radical cure.
