Intelligent prosthesis is going to be a research focus recently with the increment of the transfemoral amputees and the devel-opment of microelectronic technology, control technology and so on. As the fundamental part of the lower extremity prosthetics, the knee prostheses with high performance is still hard to design. This paper reviewed the development of the intelligent knee prostheses, classified the current available prostheses in the term of construction design, and discussed the drawback of their design and the trend of the further de-velopment.

Objective To study the clinical and pathological characteristics, treatment results and prognosis of primary parotid non-Hodgkin's lymphoma (NHL). Methods All of our 21 patients received operative resection first and were histologically comfirmed as having T-cell (intermediate grade) and 20 B-cell lineage (2 high grade, 6 intermediate grade ,12 low grade) including 7 mucosa-associatied lymphoid tissue (MALT) phenotype. Ann Anbor stages were 16 stage Ⅰ E and 5 stage Ⅱ E lesions. All patients were treated by radiotherapy,of them 11 were also given 2～6 cycle chemotherapy. Results The overall 5-year survival rate was 77.0%. All 5 patients who died did so of distant involvement. Conclusions Our data show that MALT lymphoma can be present as a primary paroid NHL,although it is not included in the Working Formulation. Low-dose radiotherapy is of choice in the treatment. Patients with intermediate or high grade NHL should be given multi-modality therapy.

0. 05). Conclusions Panipenem and betamipron are effective and safe drugs in the treatment of serious in-hospital infection in elderly patients.

ObjectiveTo investigate the improvement of speech in patients with increased blood pressure(BP) and stable blood pressure during speech therapy. MethodsAfter monitoring blood pressure with dynamic blood-pressure meter during speech therapy, patients were divided into increased BP group and stable BP group. Patients received two-month speech therapy, then their score changes in ABC examination of pre-treatment and post-treatment were compared. ResultsIn oral expression, score changes in increased BP group were significantly different from those in stable BP group (P<0.05). In listening comprehension, score changes had no significant difference between two groups(P>0.05). Conclusions Patients in increased blood pressure group progressed obviously in oral expression.

Objective To investigate the relationship between self-efficacy and positive degree in patients with cervical spondylosis.Method A questionnaire survey was conducted among 98 patients with cervical spondylosis.Results The self-efficacy score was 6.30±1.56,the score on the positive degree was 53.76 ±12.53.The self-efficacy and positive degrees were positively correlated (r=0.531,P＜0.001).Conclusions The patient's self-efficacy and positive degree are at medium level.Nursing staff should take corresponding measures to improve self-efficacy of cervical spondylosis patients,in order to improve its positive degree and achieve the purpose of effective self-management and health promotion.

Objective To explore the influence of various concentrations of amino acid on the stability of neonatal parenteral nutrition solutions .Methods Five formulations were designed with 5 different amino acid concentrations containing the same components .The final amino acid concentrations of admixtures were 0%, 1%, 2%, 3%, and 3.5%, respectively .The appearance , pH, and osmolality were observed or meas-ured after preparation (0 hour) and at 12, 24, 48 and 72 hours after preparation.The average size and the size distribution of the lipid globules were also evaluated by laser nanometer particle size analyzer .Results There was no observable alteration in color , phase separation , precipitate , and flocculation in any admixture at any of the observation time points.The mean pH values for all groups were between (5.49 ±0.01) to (6.19 ±0.01) within 72 hours.The mean osmolalities for all groups were between (774 ±3) to (1106 ±13) mOsm/kg.The mean diameters of lipid globules for all groups were between (280.6 ±0.7 ) mm to (332.2 ±2.0 ) nm.The mean polydispersity for all groups were between (0.200 ±0.011) to (0.245 ±0.012).The enrichment of ami-no acid concentration was linked to lower pH ( P=0.000 ) , higher osmolality ( P=0.000 ) and larger average lipid globules size ( P=0.000 ) .However , there was no distinct linear dependence between amino acid concen -tration and polydispersity value ( P=0.628 ) .Conclusion After 72 hours of storage at room temperature , the appearance, pH, osmolality, and the average lipid globules diameter of the parenteral nutrition solutions are within the safe range when the amino acid is not contained or the concentrations are no more than 3.5%.

OBJECTIVETo discuss the application and clinical effect of damage control concept in the treatment of severe limbs fractures combining with multiple trauma.

METHODSFrom July 2009 to July 2012, 30 patients with severe limbs fractures combining with multiple trauma were treated with the damage control concept, included 20 males and 10 females with an average age of (34.03 ± 12.81) years old ranging from 20 to 60 years old; the ISS averaged (35.00 ± 12.81) points (ranged from 26 to 54 points). And the control group also contained 30 patients with severe limbs fractures combining with multiple trauma treated by the traditional operation from June 2006 to June 2009, there were 23 males and 7 females with an average age of (34.23 ± 11.04) years old ranging from 18 to 65 years old. The ISS averaged (35.56 ± 11.04) points (ranged from 26 to 51 points). The age, gender, ISS, Gustilo classification, operation time, intraoperative blood loss, blood transfusion,postoperative complications and mortality rate were observed and compared.

RESULTSIn the damage control concept group,there were 28 cases surviving and 2 cases (6.7%) death; 6 cases of postoperative complication included 2 cases of adult respiratory distress syndrome, 1 case of multiple organ failure, 1 case of disseminated intravascular coagulation and 2 cases of wound infection. In the control group, there were 22 cases surviving and 8 cases death(26.7%); 13 cases of postoperative complication included 4 cases of adult respiratory distress syndrome,2 cases of multiple organ failure, 2 cases of disseminated intravascular coagulation and 3 cases of wound infection. There were no statistically significant differences between two groups in age, gender, ISS, Gustilo classfication and complication (P > 0.05), however there were statistically significant differences in mortality rate, operation time, blodd loss, blodd transfusion between two groups (P < 0.05).

CONCLUSIONDamage control concept is used to treat severe limbs fractures combining with multiple trauma which has the rapid and effective therapy, can improve survival rate and reduce complication.

Objective To explore the effects of three- stage swallowing rehabilitation on the swallowing a-bility of stroke patients with dysphagia. Methods 60 stroke patients were divided into primary cerebral infarction and primary cerebral hemorrhage groups, then further divided into treated and control groups randomly. All groups were given the same routine internal medicine treatment. Patients in the treated group were given three stage swallo-wing rehabilitation training additionally. All patients were assessed using Caiteng's Grading Method at the outset and at the end of the 2nd week, the Ist month and the 2nd month. Results Swallowing function scores in the treated groups were higher than those in the control groups at every stage (P≤0.05). The treated groups' scores also im-proved more quickly than those in the control groups. Conclusion Three stage swallowing rehabilitation can signifi-cantly improve stroke patients' swallowing function.
