Extranodal NK/T cell lymphoma is a kind of disease that is associated with EB virus infection and characterized by progressive distruction and necrosis of the nasal cavity and midline facial tissues, with histological features of diffuse lymphomatous cells inflitrate and inflammatory cells as abackground or angiocentric and angioinvasive inflitrate.The prognosis is poor,as it is highly aggressive and it can progress rapidly.This article mainly discusses and reviews the progress in treatment methods.

Objective To develop an alignment technique based on the movement of body gravity center. Methods As join forces in the system of balance is zero, the position of body gravity center can be calculated by body gravity which is taken from weight sensors, by the special software. Meanwhile, the position of body gravity will be sent to control unit, which can be transformed to driving signal of motor. The sliding table with laser, linked to motor, can make pursuit movement following with body gravity. A precise alignment can be made as the movement of body gravity. The balance function test is also used to make an assistant estimate for the alignment. Results and Conclusion An alignment technique has been developed for the fit of prosthesis and orthotics.

We developed a three-dimensional finite element model of the shoulder glenohumeral joint after shoulder arthroplasty including humerus shaft, scapular, scapular cartilage and eight muscles, while each of the muscles was simulated with 50 spring elements. To reduce the element number and improve the analytical precision, we used mixed tetrahedral and hexahedral elements in the model. We then used the model to calculate the biomechanics of the shoulder glenohumeral joint after hemiarthroplasty during humeral external rotation. Results showed that the maximum joint reaction force was 374.72 N and the maximum contact stress was 6. 573 MPa together with the contact areas at 40 degrees external rotation. These might be one of the reasons for prosthetic disarticulation, and would provide theoretical bases to prosthetic design.

ObjectiveFollow-up of the clinical outcome of prosthetic disc nucleus replacement on patients with lumbar intervertebral disc herniation. Methods16 patients with lumar intervertebral disc herniation were implanted prosthetic disc nucleus from June to August 2003, including 10 males and 6 females. The operation levels were at L4-5 in 10 patients and L5~S1 in 6 patients. All patients were followed up from 28 to 32 months (averaged 30 months). The contents include pain, physical examination, Short-form of McGill Pain Questionnaire investigation, Visual Analogue Scales(VAS) and Present Pain Intensity(PPI), X-ray and MRI examination, etc. ResultsAfter surgery, 16 patients experienced clinical symptom relief, the displacement of PDN in 1 case and dislocation in 1case, the height of intervertebral space becoming narrower in 5 cases and endplate subsiding in 1 case. ConclusionProsthetic disc nucleus replacement acquired satisfactory after operation, but some complication may occurre in long-term.

In order to summarize and perfect the basic skill practicing method in acupuncture teaching and form a characteristic teaching, the research on skill training and technique improving of acupuncture and tuina major was carried out. The undergraduate students in acupuncture and tuina major from College of Acupuncture-Moxibustion and Tuina were randomly divided into an experimental group and a control group. Students from both groups received the basic courses of acupuncture-moxibustion and tuina as requested in the syllabus and the special teaching was added to the experimental group, namely "three practice" (strength practice, coordination practice, targeted practice of acupuncture basic skills) and "three enlightenment" (technique enlightenment, mind and qi enlightenment, efficacy enlightenment). During and after the courses, the teaching effectiveness was evaluated on the basis of needling manipulation. The peacetime score in the experimental group was superior to that in the control group (38.03 +/- 1.14 vs 33.25 +/- 1.31, P < 0.05), the total score in the experimental group was superior to that in the control group (84.03 +/- 6.30 vs 78.05 +/- 6.55, P < 0.05). The special teaching method of "three practice" and "three enlightenment" can improve the effect of skill training teaching method. It highlights the unique feature of central plains by integrating the essence of Shaolin internal qigong and Chen-style Taiji, it can also provide new ideas for the practical teaching of TCM professional courses and the construction of characteristic professionals.

Objective To analyze the examination results of external quality assessment(EQA) at all levels of iodine deficiency disorders(IDD) laboratories in Henan province and the network operation to further standardize and improve the laboratory,and to provide reliable laboratory quality assurance for surveillance and control of IDD.Methods The examination results of EQA at all levels of IDD laboratories in Henan province were statistically analyzed in accordance with the National Reference Laboratory (NRL) of IDD (1999-201 1).Results The survey results showed that the provincial level laboratory was all qualified in testing urinary iodine and salt iodine in the past 13 years.In prefectural level,the laboratory response rates were 100.0%,and through participation in EQA,laboratory capacity had been significantly increased and stabilized.From 1999 to 2001,the passing rate of check up of urinary iodine was 22.2% (4/18),72.2% (13/18),94.4% (17/18),respectively,and the rate was stable at 100.0%(18/18) from 2002 to 2011 except 94.4% (17/18) in 2003.Since 2000,the prefectural level laboratory began to take part in the salt iodine EQA,and the laboratory response rate was 100.0% (18/18) from 2000 to 2011.Except 88.9%(16/18) in 2003,the passing rate of check up of urinary iodine was 100.0%(18/18)from 2000 to 2011.In 2003 and 2004,6 to 7 county-level laboratories participated in the EQA of urinary iodine in Zhengzhou city,respectively,and all qualified.The number of county-level laboratories that participated in the salt iodine quality control network increased from 29 in 1999 to 148 in 2011.Response rate was 94.4%(68/72),96.7%(58/60) and 92.3%(144/156)in 2003,2006 and 2007,respectively,and the rate remained stable at 100.0% in the remaining 10 years.In 1999,the passing rate was 69.0% (20/29),then increased significantly,except 86.7% (26/30) in 2001 and 84.6%(132/156) in 2007,the rates were all above 90.0% in other years,especially in 2000 and 2009,the passing rates were both 100.0%.Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions and detection techniques.

Objective To investigate whether leukotriene D4 (LTD4) regulates eotaxin-3 (Eot-3) expression in bronchial epithelial cells, and study effect of pranlukst on the regulation.Methods BEAS-2B cells and normal human bronchial epithelia cells were pre- treated with LTD4 for 1 hour,stimulated with interleukin-4, the cells were incubated for 24 hours. Eot-3 protein in supernatant were measured by enzyme linked immunosorbent assay(ELISA). The cells were pretreated with pranlukast in different concentration, then the above procedure was repeated. Results The untreated bronchial epithelial cell expressed Eot-3 protein on a very low level. After stimulating with IL-4 and incubating for 24 hours, Eot-3 production increased significantly. Pretreating the cells with LTD4 enhanced the inducing effect of IL-4. Pranlukast inverted the upregulation of LTD4. Conclusions Upregulating the expression of Eot-3 induced by IL-4 on bronchial epithelial cells may explain partially the mechanism of leukotrienes involving airway allergic inflammation of asthma. The invertion impact on upregulation of LTD4 by pranlukast may be one of mechanisms that leukotrienes receptor antagonist cure asthma.
