Extramedullary plasmacytoma (EMP) are often located in the head and neck region, commonly affecting the nasal cavity, tonsillar fossa and oral cavity but rarely the retropharyngeal space. In this report, a 60-year-old woman with large EMP in the retropharyngeal space is presented, who was diagnosed by pathology, bone marrow aspirate and computed tomography scan. The patient received operation and postoperative radiotherapy with dose of 50 Gy. At sixteen months follow-up, the patient was doing well with no signs of recurrence.

[Objective]To evaluate the value of distraction osteogenesis for treatment of deformity of spine during development.Distraction osteogenesis could be used for patients with campylorrhachia,dwarfism eccyliosis of spine or those combined with thoracocyllosis and obliquity pelvis.[Method]According to the principle of Halo-pelvic distraction apparatus which was divided into two parts of halo and pelvic,the halo was 4-nail fixation and the pelvic was 2-nail fixation.The halo and pelvic were connected by 4 standing pillar.Through the daily extending of 4 standing pillar the curved spine was extended and stretched gradually.As a result,action of 3D correction of deformity of spine was achieved.[Result]Ten patients of this group were treated by this methods.The action of 3D correction and automatic correction of deformity were showed in 70~120 days distraction that the wedge-shaped vertebra changed into squareness,curved spine was stretched and rotatory vertebra was reduced.[Conclusion]Distraction osteogenesis is a minimally invasive surgery instead of internal fixation of spine for the treatment of deformity of spine during development.

Objective To explore the relationship between the expression of MDR1 gene in liver cell and the formation of cholesterol calculus in gallbladder.Methods The mRNA expression level of MDR1 gene in liver cell of the cholesterol calculus group and the normal control group were measured through reverse transcriptionpolymerase chain reaction (RT-PCR), and microglobulin ?_2 was used as internal contrast.Results The MDR1 mRNA expression level of the cholesterol calculus group was lower than that of the normal control group(1.30?0.19 vs 2.25?(0.28), P

Since 2000,most of H5N1 subtype influenza A virus had a unique mutation of NS gene with 15base pair deletion from 263 to 277. In order to investigate the bio-characteristics of this mutation,two different NS recombinants,RWSN-248 and RWSN-m248,were generated via plasmid rescue from A/WSN/33(H1N1) and A/SD/04(H5N1). RWSN-248 had a higher viral titer than RWSN-m248 in MDCK and COS-1 cells that have an IFN response,but they had the similar growth ability in Vero cells that lack an IFN response. Both of two recombinants grew well in embryonated chicken eggs and had the similar viral titer and MDT. The results above revealed that the deletion from 263 to 277 sites of NS gene did not influence viral virulence to but decreased viral anti-IFN ability of H5N1.

Objective To investigate the effect of aspirin on the incidence of thromboembolism in hypertensive patients associated with paroxysmal atrial fibrillation.MethodsFour hundred hypertensive patients with paroxysmal atrial fibrillation (mean age 59 years) free of thromboembolic events were randomized assigned to receive aspirin (0.3 g/d) or placebo. Cerebral thromboembolism,including transient ischemic attack and embolism of peripheral arteries were defined as primary outcomes. Event-free survival curves were estimated by Kaplan-Meier curve. Results During 3.6 years follow-up,primary outcomes occurred in 61 patients (4.3% per year). Aspirin significantly reduced the incidence of primary outcome as compared with placebo group( 9.0% vs 21.5%,P

In this paper,a pulsed magnetic fields stimulation instrument is designed and realized,which provides a pulsed magnetic field with the range of maximal intensity from 0.01~2T,frequency from 0.2~100Hz and time width of pulse from 0.01~1ms.The instrument,controlled by the hand,foot or itself,can display stimulus intensity and times and output trigger signals with different waveforms to make measuring devices operate synchronistically.

Objective:This study is designed to analyze the relationship between different modes and the effect of bilingual teaching of Pathology in medical colleges for nationalities and improve the bilingual teaching efficiency of medical college for nationalities.Methods:We conducted a mode-control study to analyze the association between the three Chinese-English Teaching Modes [namely:Chinese(100%)Schoolteaching Mode with English(100%)multimedia courseware(Mode1),Chinese(100%)Schoolteaching Mode with Chinese-English multimedia courseware(Mode2),and Chinese(50%)and English(50%)Schoolteaching Mode with Chinese-English multimedia courseware(Mode 3)] and the levels of medical basic and medical English for pathology of the students(139),who had learned the course of pathology by ways of different bilingual teaching modes,from The Nursing-Speciality For Undergraduate Students(Majors In English),by Logistic Regression Analysis methods.Results:Compared with the individuals learning by Mode 1 or 2,the students who learned by Mode 3 possessed higher levels of medical basic and medical English for pathology(adjusted ORs=7.33 and 9.53,respectively,P
