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 evaluate the accuracy and comparability of secondary hematology analyzer for platelet enumeration in order to determine the accuracy and reliability of assigned value of fresh blood.Methods The results between secondary standard hematology analyzer and the reference method of platelet enumeration of 40 specimens were compared according to the document from CLSI EP9-A2.The correlation and bias were calculated.At the same time,the results of secondary standard hematology analyzer between our laboratory and Japan reference laboratory were compared.The fresh blood from normal people was prepared to be used as calibrator after assigned value by secondary standard hematology analyzer.And 36 hematology analyzers were performed correctness validation and calibrated by 36 fresh bloods.Results The results of 40 specimens by secondary standard hematology analyzer and the reference method were ( 108 -326) × 109/L and( 110 -327 ) × 109/L respectively.Correlation coefficient between the secondary standard hematology analyzer and the reference method was 0.993.The bias between two methods was from -3.8％to 3.4％.The results of NCCL and Japan reference laboratory from 2009 to 2010 were( 185 -203) × 109/L and (185 - 198) × 109/L The bias range between our laboratory and reference laboratory in Japan was from - 1.4％ to 3.7％.The ranges of coefficient variations of two laboratories were from 2.0％ to 3.0％ and from 2.6％ to 3.4％,respectively.The biases of 20 hematology analyzers were from - 2.6％ to 2.1％ and they passed the correctness validation.The biases of 16 hematology analyzers were decreased from 3.4％ - 12.6％of pre-calibration to 0％ - 2.8％ of post-calibration.Conclusions The results of secondary standard hematology analyzer are assured to be accurate and comparable by the comparison of reference laboratories.It is feasible that fresh blood assigned value by secondary standard hematology analyzer can be used as calibrator for the hematology analyzer.

Objective To assess the behavior of children with tic disorder (TD),and to analyze the behavioral characteristics among children with TD at different clinic conditions.Methods Sixty-three children with TD were evaluated with Child behavior checklist (CBCL).ANOVA and t-test were used to analyze the difference in the total and individual scores of CBCL in the children classified according to the different clinical types,the severity of TD,and comorbid attention-deficit hyperactivity disorder(ADHD).Results There were no significant differences among the total and individual scores of CBCL in the patients of the different clinic types( P ＜ 0.05 ) ;the scores of body complain in the patients in moderate to severe conditions (4.15 ± 2.34) were higher than that of those in mild condition ( 2.68 ± 2.22 ) ( t =- 2.540,P =0.014) ; the scores of attention problem (9.94 ± 3.57 ),disciplinary offence ( 3.94 ± 3.06 ),aggressive behavior ( 15.39 ± 5.12 ),exportoriented behavior problems ( 13.98 ± 7.34)and behavior problem (47.89 ± 17.51 )in TD comorbid ADHD were higher than in simple TD group ( 7.31 ± 3.34,2.44 ± 2.22,7.24 ± 4.93,9.78 ± 6.55,37.07 ± 17.98 ) ( t =- 2.774,- 2.166,- 1.930,- 1.956,- 2.174,P =0.007,0.034,0.048,0.04 1,0.034 ).Conclusion Children with TD at different clinical conditions have varied behavioral problems and behavioral characteristics,while comorbid ADHD is the most significant factor to affect TD patient's behaviors.

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%.
