Studies in recent years have suggested that the basic characteristics of the identified cerebral autosomal dominant arteriopathy with subeortical infarcts and leukoencepha-lopathy (CADASIL) are the onset of the disorder with a form of familial hereditary, middle-age onset with progressive ischemic stroke-like course and multiple diffuse white matter lesions, the identified MRI abnormal white matter signals and pathology. Molecular genetic studies have suggested that the multiple mutations of the Notch3 gene are associated with CADASIL. The combination of gene diagnosis with peripheral tissue biopsy may be the most valuable diagnostic means before death. To study CADASIL from the aspects of pathogenesis and clinical manifestations contributes to improve clinical diagnosis rate.

Objective To evaluate the clinical effects in t he treatment of femoral peritrochan teric frac-tures by PFN(proximal femoral nail).Methods A retrospective analysis was done in the treatment of femoral peritrochanteric fractures(72cases).38cases were male and 44cases female.Their age ranged 64～96years old with the average age being 78years old.70cases were intertrochanteric f ractures(EvensⅠtype 16,Ⅱtype 31,ⅢA type 14,ⅢB type 6,Ⅳtype 3),and 2cases subtrochanteric fractu res.Results65patients were followed up for over 6months.All fractures healed and all patients could take care of themselves and were satisfied with t he clinical curative effect except one patient who had the lag screw pulled o ut and coxa vara because of serious os-teoporosis.Conclusion PFNis a better way to cure femoral peritrochanteric fractures because of few complications and simple surgical procedure.Bein g a micro-trauma technique,it is worthy of wide application in clinic.[

So far, the method of detection of patent foramen ovale (PFO) by transcranial Doppler (TCD) has had two decades of history. Standardization in contrast-enhanced transcranial Doppler US procedures for cardiac right-to-left shunt detection was proposed in the Venice Consensus Paper in 1999, and some questions were raised at the same time. Over the past 10 years, the researchers have conducted a more in depth study on the method. This article reviews the related research progress.

According to the traditional point of view,CT and lumabar puncture are the main means in the diagnosis of subarachnoid hemorrhage(SAH).The values of conventional MRI T1-weighted imaging(T1WI)and T2 weighted imaging(T2WI)are very little in the diagnosis of SAH.With the development of MRI technique and the research and application of novel MRI sequences,the value of MRI are gradually recognized and affirmed in the diagnosis of SAH.and has shown its superiority.MRI isn't inferior to CT in the diagnosis of acute SAH.evidently superior to CT in the diagnosis of subacute,chronic and atypical SAHs and superior to CT in the diagnosis of the complications of SAH.MRI is valuable in screening for intraeranial aneurysms and postoperative follow-up.

Objective To explore the relationship between retinal nerve fiber layer (RNFL) thickness and central corneal thickness (CCT) in myopia eyes.Methods 91 cases (91eyes) were selected from ophthalmological outpatients including 28cases with low myopia ( spherical equivalence [ SE ] ＞ -3.0D), 33 cases with moderate myopia (SE -0.3D ～ -6.0D) and 30 cases with high myopia (SE ＜ -6.0D).All patients received ocular standard examination including intraocular pressure, refraction, slitlamp biomicroscopy and fundus examination.Other ocular diseases except refractive error were excluded.RNFL thickness and CCT were measured by RTVue Fourior-OCT ( Optovue Inc, USA).Refraction diopter was shown as SE.Results The mean RNFL thickness and CCT was ( 108.5 ± 10.1 ) μm, (524.7 ±36.8)μm respectively.These were no significantly different among low, moderate and high myopia ( P ＞ 0.05 ).Temporal RNFL thickness( tl1 ,tu1 ) was significantly positive related with CCT( r =0.281,0.093 of tl1, r= 0.352,0.167 of tu1 respectively in single and multiple variable analysis; P ＜ 0.05 ), nasal ( nl2, nu2)and inferior nasal RNFL thickness( in2,in1 )was significantly positive related with SE( P ＜0.05), inferior temporal RNFL thickness( it2)was significantly negative related with SE( P ＜0.05), and RNFL thickness in other regions were not significant related with CCT and SE ( P ＞ 0.05 ) in single and multiple variable regressive analysis.Conclusion Relationship between RNFL thickness of local paradisc region and CCT in myopia eyes suggested that CCT should be correlative with some sensible structural parameters in glaucomatous neuropathy and might be important in the diagnosis and therapy of glaucoma.

Transient ischemic attack (TIA) traditionally refers to temporary brain dysfunction lasting no longer than 24 hours due to a shortage of blood and oxygen, without any residual neurological deficit. In recent years, the development of imaging technology enables us to have a new awareness about TIA. This article reviews the effects of MRI, especially diffusion-weighted imaging, in the diagnosis and prognostic prediction of TIA.

Objective This paper was conducted to study the preparation methods and the hypoglycemic effects of oral sodium alginate-insulin nanoparticles (INS-NPs) on the blood glucose level in Streptozotocin-induced diabetic Wistar rats. Methods The INS-NPs were prepared by an ionic gelation method. The changes of the morphology and size of the INS-NPs were examined by transmission electron microscope and Zetasizer 3000HS. The hypoglycemic effects of the INS-NPs were evaluated by monitoring the blood glucose levels in streptozotocin-induced diabetic Wistar rats. Results The INS-NPs were spherical or ellipsoidal in shape with a diameter of 236.4?19.3nm. The entrapment efficiency and load efficiency of INS-NPs were 78.5%?6.1% and 22.6%?4.4%, respectively. In vivo hypoglycemic study showed the levels of blood glucose of diabetic Wistar rats declined at 7h after oral administration of INS-NPs (26U/kg). Their hypoglycemic effects were maintained for 12h and the levels of blood glucose were kept with normal range for 6h (less than 7.0mmol/L). Conclusion The INS-NPs have the hypoglycemic effect on the blood glucose level of streptozotocin-induced diabetic rats.
