Chinese Journal of Rehabilitation Theory and Practice 2016;22(9):1080-1085
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.

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.

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.
