BACKGROUND: At present, MRI is the key method to examine the hippocampal sclerosis of the patients with epilepsy. The main results are the abnormal signals of hippocampus, in addition, other symbols of MRI can also suggest the hippocampal sclerosis.OBJECTIVE: To study the significance and value of the loss of visualization of digitations of hippocampal head in diagnosis of hippocampal sclerosis through the analysis of MRI on patients with temporal lobe epilepsy.DESIGN: Non-randomized, blind procedure(data selection, result evaluation), blank controlled and clinical experiment.SETTING: Departments of radiology in two universities.PARTICIPANTS: Between September 1996 and December 2002, 18 patients with temporal lobe epilepsy were selected from the Department of Radiology,Xinhua Hospital Affiliated to Shanghai Second Medical University. Meanwhile,patients with headache were diagnosed with MRI. Eighteen healthy people,whose ages were matched, were as control group.METHODS: Among 18 patients, MRI of 16 patients and 18 people in the control group were performed with a GE 1.5T Horizon MR unit and another 2with a GE 1.5T Signa whole body MR unit. With the double blind procedure, whether the digitations of hippocampal head of 72 hippocampal heads of 36 people in both patient and control groups exist or not was recorded by two radiologists with knowledge of hippocampal dissection but without knowing the condition of clinical operation. The results were divided into 3 levels:loss, poorly visible and existing, and hippocampal atrophy and abnormal signals were also recorded.MAIN OUTCOME MEASURES: Image condition of digitations of head,size of hippocampal head and changes of signal.RESULTS: Of 18 patients with hippocampal sclerosis, the abnormal findings included smooth and the loss of visualization of digitations of hippocampal heads seen in 16 patients, poorly visible of digitations of hippocampal head in one patient, and existence of digitations of hippocampal head in one patient. Hippocampal atrophy and high signals on T2-weighted images and fluid-attenuated inversion recovery imaging were seen in all patients. The sensitivity of loss of digitations of hippocampal heads for diagnosis of hippocampal sclerosis was 88.9% (16/18), and the specificity was 100%.CONCLUSSION: The loss of visualization of digitations of hippocampal head is a sensitive indicator for the diagnosis of hippocampal sclerosis. Atrophic changes of hippocampus combining with the increase of T2-weighted signal can definitely diagnose the hippocampal sclerosis.

Objective To analyze the clinical features of hepatic veno-occlusive disease (HVOD) and to explore the diagnosis criteria and treatment.Methods A total of 50 cases of HVOD administrated at The First Affiliated Hospital of College of Medicine,Zhejiang University from August 2008 to August 2011 were analyzed for etiology,clinical manifestation,laboratory examination,image,pathological features and treatment.Results Among the 50 HVOD cases,38 cases (76％)had a history of taking Gynura segetum.The main clinical manifestations were ascites,hepatomegaly,right upper quadrant pain,jaundice,and weight gain.Laboratory examinations indicated liver function injury and increased serum CA125 level.Color Doppler ultrasound showed hepatomegaly,decrease in diameter of hepatic vein and slow blood flow.The computed tomography scan suggested hepatomegaly,enhanced scan showed liver inhomogeneous enhancement at portal and delayed phase,map-like changes and markedly decrease in diameter of hepatic vein.Pathological examination suggested hepatic sinusoid congestion,central vein stenosis and vessel wall thickening.The main therapy was anticoagulant treatment.One case cured,33 cases improved,13 cases uncured and three cases died.Conclusions HVOD because of taking Gynura segetum is common in Zhejiang Province,which can be diagnosed according to medical history,clinical manifestations, and typical image characteristic.However,diagnosis of the atypical cases still needs liver biopsy.Anticoagulation therapy can achieve better efficacy.

Objective To evaluate the feasibility,efficacy and complication of early middle cerebral artery(MCA) mechanical recanalization(MER) for treatment of acute ischemic stroke.Methods Seven cases undergone MER of MCA for the treatment of acute cerebral infarct were retrospectively reviewed and analyzed,including the etiology,mechanism,Qureshi grading scale,location and size of infarcts,NIHSS score of pre and post procedure,endovascular technique and complications.Referring to the literature,the indications of MCA recanalization were further identified.Results A total of 7 cases with mean age of 48 yrs were reviewed,which included 3 cases of atherosclerotic thrombosis and 4 embolic cases with pre NIHSS score ranging from 3 to 22.Mechanical recanalization succeeded in 6 cases,but 2 cases of cardiogenic embolism died of intrac ranial hemorrhage postoperatively.Favorable clinical outcomes were achieved in 4 cases whereas 1 deteriorated.Overall complications seemed to be consistent with literatures reviewed.Conclusions Early MER of MCA may benefit to a certain subset of acute ischemia stroke patients,however,embolic cases,elder patients and those with severe neurologic deficits are often accompanied by higher complications and unfavorable outcome.

OBJECTIVE:To establish and validate the method for the determination of carbamazepine (CBZ) in human plas-ma,and to apply the method for external quality assessment. METHODS:After precipitated with acetonitrile,the plasma sample was determined by LC-MS/MS. Using loratadine as internal standard,the determination was performed on Kromasil C18 column with mobile phase consisted of water (containing 0.1% formic acid)-acetonitrile (gradient elution) at flow rate of 0.6 ml/min and column temperature of 40 ℃. The ion transitions under MRM mode by ESI+ ionization were performed at m/z 237.1→194.0 and m/z 383.1→267.0 for CBZ and internal standard,respectively. RESULTS:The linear range of CBZ were 5-1 000 ng/ml (r>0.998). The limit of quantitation was 5 ng/ml. RSDs of inter-day and intra-day were 1.00%-6.42%;relative deviation were -6.93%-0.32%. The external quality assessment of 5 samples were 679.0,475.0,104.0,29.2 and 26.2 ng/ml,respectively. The pass rate of assess-ment result was 100%. CONCLUSIONS:The method is sensitive,accurate and specific. The method is applicable for the plasma concentration determination and external quality assessment of CBZ.

Methods Thirteen cases of anastomotic stenosis after surgical correction of esophageal atresia were enrolled, age ranging from 3 to 10 years. Barium esophagography before balloon dilation showed the diameter of esophageal stenosis ranging 1 to 3 mm and the stenosis was dilated by using balloons of 6 to 12 mm diameter. Results All the 13 cases obtained complete resolution of the stenosis after dilation for twice or thrice. There was no esophageal perforation or other complications with a period of clinical symptomless of 6 to 30 months. Conclusions Ballon catheter dilation is a simple, safe and reliable method for treating anastomotic esophageal stenosis in infants.

Objective To evaluate the role of interventional therapy in Wilm's tumor, renal vascular lesions and ureter stricture in children. Methods Thirty-eight cases were analysed, including 18 cases of Wilm's tumor treated with preprocedural chemotherapy and embolization through renal artery, and 13 cases of unknown-reason hypertension with selective renal arterial angiography for venous blood renin including undergone some patients PTA. Six cases of ureter stricture were dilated with balloon and 1 with hematurea by small aerial embolization. Results After embolization, Wilm's tumors showed reduction in vascularization and reduction in size too. The surrounding tissue of the tumor had a clear demarcation with the normal tissue, decreasing the dissemination to blood and distal metastasis. Renal vascular hypertension was clearly diagnosed and treated, and the increase of renin was helpful to the diagnosis of unknown-reason hypertension. And the obstruction of ureter was improved. Conclusions Interventional therapy is feasible in the application of urinary system diseases with great significance clinically.
