Objective To analyze implanted children's production of vowels and to investigate the features of vowels production .Methods Thirty CI children averaged 32 .65 ± 5 .97 months were enrolled in this study .Using 19 Chinese vowels as test materials ,accuracy rates were statistically analyzed to get the difficulty gradient and main error patterns .Results /a/and /e/were the easiest vowels and /üe/,/uai/,/ü/were the most difficult vowels for CI children .From the mouth shape of vowels ,the difficulty gradients from easy to difficult were open -mouths →e-ven-teeth → close-mouths → pursed -mouths .From the structures of vowels ,triphthongs were the most diffi-culty ,while single vowels and diphthongs shared the same difficulty level .High vowel's nasalization ,the deletion of diphthongs and triphthongs ,the separation of diphthongs and triphthongs and the substitution of /o/,/ü/,and /ai/were the main error patterns .Conclusion The difficulty levels of vowels'production for CI children at average age of 31 months are rather obvious .Compared with aided children ,they show some common developmental sequences and error patterns ,but also reflect their own characteristics .When in vowel articulation therapy for little CI children ,we should provide targeted training according to error patterns on the basis of following their sequences of difficulty level to fa-cilitate their efficiency .

Objective To evaluate the additional efficiency of aldosterone blockers (AB) during angiotensin Ⅱ receptor blockers (ARB) treatment on hypertensive left ventricle hypertrophy in the elderly. Methods Forty-five cases of hypertensive left ventricular hypertrophy detected by Doppler ultrasonic cardiogram examination were enrolled,and were randomized to receive treatment with ARB plus AB (Group A) or ARB plus diuretics (Group B) for 48 weeks. The indicators of left ventricle hypertrophy were checked before and after the treatment. Results The both regimens could significantly decrease the blood pressure,and there was significant difference in the effects on lowering blood pressure between the regimens. Both regimens could alleviate left ventricle hypertrophy,but the regimen of ARB plus AB was superior to the regimen in Group B. Conclusion The addition of AB treatment during the ARB treatment was a good antihypertensive regimen for reducing left ventricle hypertrophy.

Objective To observe the effects of treadmill training on hindlimb motor recovery and noradrenaline (NA) fibers in rats with spinal cord contusion.MethodsSpinal cord contusions at the T10 level were induced in 3-month old female SD rats by dropping a 10 g rod from a height of 25 mm.The injured rats were then randomly divided into a control group and a treadmill training group ( n =15 in each group).Treadmill training began 1 week post-injury.No treatment was administered to the control group rats.Hindlimb motor function was evaluated weekly from the 1 st to the 9th week post-injury using Basso Beattie Bresnahan (BBB) scores and average combined scores (ACOs).The expression of dopamine beta hydroxylase (DBH) in the spinal cord caudal to the injured area was detected by immunohistochemical staining.ResultsThe treadmill training group exhibited significantly greater improvement in BBB scores from the 3rd week to the 7th week and in ACOs from the 2nd to the 9th week post-injury compared with the control group.The number of DBH positive fibers in the injured spinal cords and the number of DBH positive neurons in the injured frontal horns were also significantly higher in the training group.ConclusionsTreadmill training can promote the recovery of hindlimb motor function in rats after spinal cord contusion,perhaps by increasing the number of DBH positive fibers and DBH positive neurons.

Objective To compare the effects of health education on fat intake behavior and its psychology in students with different BMI,provide evidence for improving individual healthy education.Methods A experimental epidemiology was used,Twenty-nine secondary school classes were randomly selected by multi-stage cluster sampling from two cities in Zhejiang province.Overweight or obesity group included all students who were judged overweight or obesity,normal group included students who were judged normal and basic matched by age,grade,sex and stage of baseline.Intervention based on transtheoretical mode was conducted on two groups and intervention results were measured by the adolescent fat intake behavior of psychological measurement scales (Chinese version).Chi-square tests,T-tests,non-parameters tests and binary logistic regression were performed for data analyses.Results Stage of students with overweight or obesity and with normal BMI all moved forward after intervention,while the proportion of stage advance for students with overweight or obesity was further than students with normal BMI.Change strategy(2.60±0.79),pros(3.58±0.90) and self-efficacy(3.01±0.72) of students with overweight or obesity better than students with normal BMI in baseline((2.34±0.86),(3.08±0.91),(2.79±0.81)) while difference was not significant after intervention.Logistic regression analysis discovered that the promotion of change strategy moved stage forward for students with normal BMI(OR=2.168,95％ CI:1.560-3.014)and promotion of self-efficiency moved stage forward for students with overweight or obesity (OR=1.801,95％ CI:1.026-3.159).Conclusion The intensity and duration of psychological intervention is essential to be reinforced for students with normal BMI,while for students with overweight and obesity,psychological intervention should be promoted in combination with social support.

BACKGROUND: Urological complication is one of common surgical complications following transplantation and severely threatens renal function, even patient's lives. Urological complications following renal transplantation mainly contain urinary fistula,ureteral obstruction and ureter backflow.OBJECTIVE: To retrospectively analyze the incidence and management of urological complications following kidney transplantation.METHODS: A total of 1 223 patient times following kidney transplants were selected at the Department of Urology, Institute of Surgery Research, Daping Hospital, Third Military Medical University of Chinese PLA from December 1993 to April 2007.According to ureter of donor kidney and the urinary tract of recipients, ureteroneocystostomy was used for urinary tract reconstitution in 948 patient times, and end-to-end ureteroureterostomy in 275 patient times. Urological complications such as urinary fistula, ureteral obstruction and vesicoureteral reflux (VUR) were treated by the different methods on the basis of the different causes, mainly by surgical procedures. Reason of urological complications, surgical management of urologicalcomplications and its clinical outcome, the 3-year survival rate of grafted kidney were measured.RESULTS AND CONCLUSION: In a total of 1 223 patients, urological complications were encountered in 92 cases (7.5%), including 43 cases of urinary fistula (3.5%), 35 ureteral obstruction (2.9%), 14 VUR (1.1%). 35 cases of urinary fistula, 29 ureteral obstruction, 6 VUR were cured by surgical procedures including ureteroureterostomy in 35 patients (50%), revision of ureteroneocystostomy in 18 (25.7%), endourology in 11 (15.7%) and other operation in 6 (9.6%). All recipients with urological complications regained normal graft function except one undoing transplanted nephrectomy due to the pelvis and urteral necrosis. There was no grafted kidney and recipient loss secondary to these complications in the present series. The 3-year survival rate of graft with urological complications and without urological complications did not show significant difference (P > 0.05). These indicated that most of urological complications following kidney transplantation request surgical management, and ureteroureterostomy are frequently used. The long-term graft survival is not affected by a correctly treated urological complication.

BACKGROUND: Urinary kidney injury molecule-1 (KIM-1) has been proved to be a novel kidney-specific injury molecule as a marker for the diagnosis of acute renal ischemia injury, and KIM-1 participated in the progress of renal injury repair. However, no one reported the significance of its dynamic expression during the functional rehabilitation of renal graft.OBJECTIVE: To investigate the relations between urinary KIM-1 level and the early renal graft function in order to provide rational approaches for evaluating or predicting early renal graft function.METHODS: The 46 patients were divided into 3 groups, including 22 cases of immediate graft function (IGF), 14 cases of slow graft function (SGF) and 10 cases of delayed graft function (DGF). The 24-hour urine specimen was collected every day for 2 weeks since the operation. The urinary KIM-1 content was detected by enzyme linked immunosorbent assay (ELISA), and at the same time the urinary and serum creatinine levels were detected. The diversity of urinary KIM-1 level was observed during the recovery of the graft function, and the clinical significance was evaluated by analyzing the correlation of urinary KIM-1 level and serum creatinine.RESULTS AND CONCLUSION: At the first 2 days after kidney transplantation, the urinary KIM-1 levels were high and no significant difference was observed between the three groups (P < 0.05). Two days later, the urinary KIM-1 level descended quickly along with the descent of the serum creatinine in IGF and SGF groups; the urinary KIM-1 maintained high levels until the serum creatinine reached normally. In DGF group, the urinary KIM-1 decreased quickly to a low level after 2 days from operation, but it increased promptly 1 to 2 days before the recovery of graft function and kept a high level until the serum creatinine reached normally. This suggested that consecutive detection of urinary KIM-1 is useful for monitoring the early graft function after kidney transplantation, and high urinary KIM-1 may suggest the recovery of graft function.

BACKGROUND: Urethral fistula following renal transplantation accounts for 40%-70% of urinary complications, owing to surgical and medical factors. OBJECTIVE: To effectively decrease and avoid attack of urethral fistula after renal transplantation, and prolong the survival of kidney. METHODS: Clinical data from 68 cases following renal transplantation were retrospectively analyzed at the levels of pathogeny, diagnosis and treatment. There were 47 males and 21 females, aging 20 58 years. Urethral fistula occurred at 3 31 days after renal transplantation, and the amount was 60-2 000 mL per day. Based on the principle of the urethral injury classification method, urethral fistula was divided into simple and complex categories, while according to the fistula site, etiology and extent, urethral fistula was divided into low, high and multiple fistula. Attack rate of simple urethral fistula and complex urethral fistula was detected following renal transplantation so as to analyze the pathogeny of urethral fistula. RESULTS AND CONCLUSION: Of 68 cases with urethral fistula following renal transplantation, 47 cases (69.1%) were simple urethral fistula, including 42 cases with ureteral end necrosis, 4 cases with lax anastomotic suture of ureter bladder, and 1 case with ureteral anastomotic badness caused by wound infection, and 21 cases (30.9%) were complex urethral fistula, including 2 cases with renal pelvis fistula, 2 cases with ureter, 11 cases with ureterovesical anastomosis region, 6 cases with ureteral necrosis longer than 2 cm. A lot of causes may induce urethral fistula following renal transplantation. The blood stream, edema, size of fistula, length of the ureter, and operative procedures are selected to ensure free of strain. Urethral fistula can be treated on time on the basis of different situations.

Objectives To explore the relationships between the current physical exercise behaviors and psychological factors of middle school students,so as to provide scientific evidence for improving health education and carrying out targeted health intervention measures.Methods The Multi-stage stratified sampling and cluster sampling method was adopted to choose 3600 students from 12 junior and senior middle schools in Hangzhou,Wuhan and Xi'an.The date was collected using the adolescent physical exercise behavior-psychological measurement scale(Chinese version).The structural equation model was built to explore the relationships between psychological factors(including the change of strategy,decision balance positive effect,decision balance negative effect and self-efficiency)and physical exercise.Results The change of strategy has biggest effect on physical exercise behaviors,with the standardized direct effect value of 0.344.The standardized direct effect value of decision balance negative effect,decision balance positive effect and self-efficiency were 0.071,0.093 and 0.169 respectively.The negative correlation among the four dimensions was significant statistically.Conclusion Psychological factors have direct effects on the change of the behaviors,and the change of the strategy has the largest impact on physical exercise behaviors of middle school students.The four psychological factors are closely correlated with one another,which is important in formulating middle school sports programs to promote the physical quality of middle school students.

ObjectiveTo investigate the expression of survivin,COX-2 and bcl-2 in non-Hodgkin lymphoma(NHL)and the significance and correlation between them.MethodsImmunohistochemistry MaxVision systems for survivin,COX-2 and bcl-2 were conducted on 44 NHL and 20 reactive lymphoid hyperplasia (RH).ResultsThe positive expression rates of survivin,COX-2,bcl-2 in NHL were 70.45 ％(31/44),68.18 ％ (30/44),63.64 ％ (28/44),respectively,and these in RH were 40.00 ％ (8/20),40.00 ％(8/20) and 20.00 ％ (4/20),respectively.There was positive correlation between the expression of COX-2 and survivin (r =0.306,P =0.043),survivin and bcl-2 protein (r =0.339,P =0.040) in NHL.ConclusionCOX-2,survivin,bcl-2 are highly expressed in NHL.To detect the expression of them has clinical value to diagnosis NHL and to estimate the malignant degree of lymphoma.There are a positive correlations between the expression of COX-2 and survivin protein,and between the expression of survivin and bcl-2 protein,which indicates that they may play a synergistic role in the occurrence and development of NHL.

Objective To evaluate musical therapy combined with sufentanil postoperative intravenous analgesia on hemodynamic changes in patient accepted lung cancer operation.Methods Sixty lung cancer surgery patients (ASA Ⅰ-Ⅱ grade) were selected and divided randomly into musical therapy (group M; n =30) and control (group C; n =30).In group M,patients accepted music relaxation training for fifteen minutes before surgery,and music intervention for one hour at 3,7,15,19 hour after surgery.Whereas,in Group C,patients did not listen to any music during the same period.In the intensive care unit,patients were connected to a patient controlled analgesia (PCA) device.The PCA device (sufentanil 2 μg/kg,100 ml saline) was set to deliver a bolus of 2 ml,with a lockout interval of 10 min and background infusion volume of 0.5 ml/h.Hemodynamic changes,the visual analog scale (VAS) and consumption of sufentanil were recorded at the 4th,8th,12th,16th,20th and 24th hour after operation.Results SBP,DBP,HR and VAS of group M were significantly decreased compared to the group C,respectively (P ＜0.05),and significant difference was found in the PCA delivery frequency [group C (30.96 ± 4.00),group M (19.06 ± 3.49),t =12.39,P ＜ 0.01] and postoperative sufentanil consumption[group C (82.65±6.19)μg,group M (52.68 ±7.07)μg,t =20.00,P ＜0.01].Conclusions Musical therapy combined with sufentanil postoperative intravenous analgesia was able to produce better analgesic effect in the treatment of patient accepted lung cancer operation,which decreased postoperative sufentanil consumption and effectively reduced SBP,DBP and HR,and relieved the patient's anxiety.
