Objective To explore the MRI features of ejaculatory duct obstruction.Methods During January 2003 to Dccember 2010,transrectal ultrasonography (TRUS) was performed for 106 patients and underwent surgical treatment for ejaculatory duct obstruction.Among them,16 patients underwent MRI examination.The MRI features of ejaculatory duct obstruction in these patients were summarized.Results Ejaculatory duct cysts,ranging in size from 4 mm ×4 mm ×7 mm to 4 mm ×4 mm ×9 mm and locating in the paramedian line,were detected in 5 of the 16 patients; ejaculatory duct dilation located in the paramedian line was detected in 7 patients,with the internal diameter of 5 to 30 mm. After contrast injection,significant enhancement of the wall of the ejaculatory duct was observed in 2 patients.Mullerian duct cysts complicated with dilated ejaculatory duct and seminal vesicles were detected in 4 patients,in whom the cysts were located in the median line,ranging in size from 4 mm × 5 mm × 6 mm to 34 mm×35 mm ×44 mm,with inverted teardrop shaped pointing toward the seminal colliculus.ConclusionThe most common MRI features of ejaculatory duct obstruction are ejaculatory duct dilation and ejaculatory duct cysts.

Objective To investigate inhibitory effects of matrine (Ma) combined with vincristine (VCR), cytosine arabinoside (Ara-c), harringtonine (HRT), adriamycin (ADM), and daunorubicin (DNR) on proliferation of K562 cells. Methods MTT colorimetric assay was used to detect the inhibition rate of Ma combined with antineoplastic on K562 cells. Results The proliferation of K562 cells was inhibited by Ma at the concentration of 160 ?g/ml to 400 ?g/ml. The inhibitory rates of Ma combined respectively with VCR, Ara-c, HRT, ADM, and DNR were significantly higher than those of VCR, Ara-c, or HRT alone (P0.05). Conclusion Ma can inhibit the proliferation of K562 cells in a dose-dependent manner. The anti-proliferation effect of VCR, Ara-c, and HRT on K562 cells could be enhanced by Ma.

Objective To established a diagnostic methods to idenfity Niemann-Pick disease type C (NPC) in China. Methods Two patients aged 5 and 20 years respectively who presented progressive neurologic regression and splenomegaly were subjected to filipin staining of cultured skin fibroblasts and genetic analyses of NPC1 gene. Results Although there were differences in onset ages and clinical presentations, filipin staining of the cultured skin fibroblasts confirmed the clinical diagnosis of NPC, showing an intense punctate pattern of fluorescence concentrating around the nuclei, consistent with the accumulation of unesterified cholesterol in NPC cells. Genetic sequence analysis further verified the results of filipin staining. The case 1 was compound heterozygous for M1142T(3425T＞C),R1186H(3557T＞C)and case 2 for Q88H(264G＞T),469_470insGT.The latter 2 mutations were novel, and the possibility of polymorphisms was not supposed by analyzing 134 DNA samples obtained form normal controls. Conclusions Filipin stainning of the cultured skin fibroblasts is a reliable method to clinically diagnose NPC with a sensitivity. Genetic diagnose should be performed where genetic analysis is allowed.

Objective To investigate effect of single anterior decompression and fusion for pinching cervical spondylosis myelopathy.Methods 82 patients with pinching cervical spondylosis myelopathy,treated with single anterior decompression and fusion,were analyzed,including 43 males and 39 females,with an average age of 54.4 years (range,33-79 years).Occupying rate,anterior occupying rate and posterior occupying rate were measured on pre- and post-operative midsagittal MRIs.Multiple regression analysis was performed between preoperative occupying rate,intervertebral space height,postoperative imaging changes and neural function recovery.Results All patients were followed up for an average of 25.8 months (range,9-72 months).Significant differences were found between pre- and postoperative Japanese Orthopaedic Association (JOA) scores,anterior occupying rate,posterior occupying rate,and intervertebral space height,respectively.Pre- and post-operative posterior occupying rate was averagely 29.0％±10.5％ and 19.9％+11.6％,respectively,and improvement rate of posterior occupying rate was 9.0％±6.1％.Regression analysis found that preoperative intervertebral space height did not relate to posterior occupying rate,while preoperative posterior occupying rate related to improvement rate of posterior occupying rate.JOA scores improved significantly after operation in patients with preoperative posterior occupying rate between 20％ and 40％.However,the decompression results were poor in patients with preoperative posterior occupying rate ≥40％.Conclusion Anterior decompression and fusion can achieve satisfactory results in patients with pinching cervical spondylotic myelopathy.For patients with preoperative posterior occupying rate between 20％ and 40％,the decompression results are better.

In order to better understand the clinical manifestation of systemic lupus erythematosus (SLE) with intracranial hypertension syndrome (IHS), we analyzed the clinical features and treatment of a typical SLE patient with IHS. SLE is one of the most unpredictable autoimmune diseases involving multiple organ systems that is defined clinically and associated with antibodies directed against cell nuclei. IHS is an uncommon manifestation of neuropsychiatric SLE (NPSLE) and is characterized by an elevated intracranial pressure, papilledema, and headache with occasional abducens nerve paresis, absence of a space-occupying lesion or ventricular enlargement, and normal cerebrospinal fluid chemical and hematological constituents. IHS has been reported in a few sporadic cases in patients with SLE worldwide, but rarely has been reported in China. In this study, a 34-year-old female SLE patient with IHS was reported and pertinent literature reviewed. The clinical presentation, image logical features, and investigatory findings were discussed.
