Objective To evaluate the diagnostic value of multi-slice thrce-dimensional computed tomographic angiography(MS-CTA) with volume rendering(VR) for Moyamoya disease.Methods MS-CTA of 25 patients with Moyamoya disease verified by DSA were restrospectively analyzed.Source images were got by GE Lightspeed pro scanner.VR was adopted to reconstruct 3D images in all cases.Results Of 25 CT precontrast,13,12 cases showed infarction and hemorrhage respectively,while 11 cases had dialated vessels in thalamus-basal ganglia region on CT.Accuracy of stenosis or occlusion of the bifurcation of ICA, proximal portion of the ACA or MCA was 88.0% (22/25) by MS-CTA.MS-CTA overestimated the degree of stenosis,MS-CTA misdiagnosed 3 cases(12.0%)with stenosis to occlusion.MS-CTA showed fewer small Moyamoya vessels than DSA.MS-CTA only demonstrated 6 cases(25.0%)with collateral vessels.Conclusion CT is still the conventional method for detecting secondary lesions to Moyamoya disease.CT and MS-CTA can accurately diagnose Moyamoya disease.

Objective To evaluate the early effect of hypoxemia on central executive function of working memory.Methods 24 patients with obstructive sleep apnea syndrome (OSAS) and 20 healthy matching controls were studied in probe retrieval task.Results In control group,both the low and high conflict identification tasks elicited the N270 component with right prefrontal [F4,(2.2?2.7) ?V]and posterior [P3,(7.0?3.0) ?V; P4,(6.9 ? 3.1) ?V] distribution. N430 was elicited in high conflict condition with right hemispheric lateralization. The positive component,P300( 300～400 ms) distributed remarkably at parietal scalp[P3,(7.0?3.0) ?V; P4,(6.9?3.1) ?V]was elicited only in identity identification task. The N270 was significantly decreased in the frontal regions in mild OSAS patients [F4,(5.0 ? 4.5) ?V]; F3,(6.0?4.5) ?V] in comparison with the controls( P

Objective To combine the active poly lactic co-glycolic acid (PLGA) nanosperes with adriamycin in side (ADM-NP) on the surface of ultrasound micrbubbles in covalent bonding and to prepare a novel drug-loading ultrasound micrbubble,and observe the physicochemical property.To quantify drug encapsulation efficiency and drug-loading amounts and drug-release properties in vitro and the effect of tumor imaging.Methods ADM-NP were prepared with double emulsification method,The surface carboxyl of ADM-NP was activated with carbodiimide method.Amino ultrasound microbubbles (MB-NH2) were prepared with mechanical shaking.The carboxyl of ADM-NP and the MB-NH2 could take place condensation reaction under a certain condition.Light microscope was used to observe the shape and distribution of the novel micrbubble.High performance liquid chromatography (HPLC) was used to quantify drug encapsulation efficiency and drug loading amounts.This novel microbubbles were put in 2 dialysis bag to observe the releasing properties of ADM in vitro,and one of the bag was using low frequency ultrasound irradiation for 120 s.The effect of tumor imaging using this novel microbubble was observed.Results After 48 hours,a number of ADM-NP attacted to the MB-NH2 like a gar land.Determination of entrapment efficiency and drug loading of it by HPLC weare (86.11 ± 6.76)％ and (8.71 ± 0.46)％.The sustained release in vitro can last for more than 48 hours.More than 90％ of ADM encapsulated in the 2 groups was sustained released for 48 hours.And the release characteristics of the 2 groups in vitro was in accord with Higuchi equation,and no difference was observed in the 2 groups (P ＞0.05).The tumor showed typical enhancement pattems of quick wash-in and quick wash-out.Conclusions To combine the nanospheres to the surface of microbubbles with covalent bonding,it could prepare a novel efficient drug-loading microbubbles for a original technique of ultrasound-targeted microbubble destruction(UTMD).

Objective To investigate the role of resilience on cognitive function in older adults.MethodsBy random sampling,a total of 321 older adults participated the present study and were investigated by Connor-Davidson Resilience Scale,Mini Mental State Examination and self-designed general questionnaire.ResultsThe score of resilience in older adults (82.75±15.13) was significantly higher than that of Chinese community people (65.40±13.90) (t=20.68,P<0.01).Older adults with poor resilience performed significantly lower on all dimensions of cognitive abilities than the other two groups (middle & higher resilience group) (all P<0.05).With both age and educational level controlled,tenacity and strength were of positive prediction for the cognitive abilities of older adults (β=0.25,0.17,P<0.05).ConclusionThere is a close relationship between resilience and cognitive function of older adults.The training of tenacity,strength and optimism will help delay the decline of cognitive function.

Currently,surgical treatments in tennis elbow include open,arthroscopic and percutaneous procedures.Open surgery,having definite curative effects,is commonly used.There are different surgical methods based on different hypotheses about the pathogenesis of tennis elbow,such as detachment of common extensor origin,resection of annular ligament,denervation surgery and resection of microvascular nerve bundle.There is a huge difference in open surgery of tennis elbow between China and abroad.Debriding or releasing extensor carpi radialis brevis and common extensor tendon are mostly used abroad though it remains controversial whether we should release or debride with tendon,as well as whether it is better to decorticate on lateral epicondyle or not.In China,tennis elbow is treated with resection of microvascular nerve bundle except for debridement and release of tendon.As for evaluation criteria,the following methods,grip strength,grading system and visual analogue scale have been used in researches.However,cure rate and response rate are valuation criteria for resection of microvascular nerve bundle in China.The evaluation criteria are different among various surgical methods,even in the methods,especially for grading system.Each research has unique standards to define excellent,good,fair and poor outcomes.Complications of tennis elbow open surgery are rare,while subcutaneous hematoma is the common complication.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.

Objective To analyze the clinical characteristics of 1126 cases of malignant lymphoma in our hospital from 2005 to 2009. Methods Age, sex, pathological classification, onset locus and clinical staging of the malignant lymphoma were analyzed and summed up, based on the data of the malignant lymphoma patient information in hospital case database from 2005 to 2009 and excluded the cases as pathology was not sure and the repeated cases. Results A male:female ratio of malignant lymphoma in inpatient was 1.94:1. The majority of Hodgkin lymphoma (HL) manifested in 20-40 years old, mixed cellularity (64.16 %) and nodular sclerosis (29.48%) was most common. The majority of non-Hodgkin lymphoma (NHL) manifested in 50-70 years old, the most common pathological classifications were diffuse large B-cell lymphoma (53.31 %), extranode nasal-type NK/T cell lymphoma (7.35 %), mantle cell lymphoma (6.40 %), B chronic lymphocytic leukemia/small B-cell lymphoma (4.30 %), anaplastic large cell lymphoma (4.09 %), precursor T cell lymphoblastic leukemia/lymphoma (3.88 %), peripheral T cell lymphoma but not otherwise specified (3.46 %), angioimmunoblastic lymphoma(3.04 %), follicular lymphoma(2.94 %), Burkitt lymphoma (2.52 %). The onset locus of both HL and NHL most often involved lymph nodes of the cervical region. Conclusion The gender, age, pathological classification, onset locus and clinical staging of malignant lymphoma were different between HL and NHL.
