Objective The purpose of this study is to evaluate the relationship between different types of partial laryngectomy and post-operative voice quality by investigating the preserved voice function and its change after the surgery.Methods The computer multimedia program of Dr.Speech science for Windows was used to obtain the acoustic parameters from 30 normal adults and 55 patients operated 5 years ago with partial laryngectomy: 20 cases of horizontal partial laryngectomy,18 cases of vertical partial laryngectomy,and 17 cases of extended partial laryngectomy.Within 5 years after operation,F0,jitter,shimmer,NNE,F1 and F2 were measured several times and were compared.Results For the patients the fundamental frequency was lower and jitters,shimmer,NNE were higher compared to the control group.The parameters of jitter,shimmer and NNE of patients with supraglottic horizontal laryngectomy were the lowest while for those with vertical partial laryngectomy they were the highest.Compared were the formant frequencies(F1)of vowels /a:/,/i:/,/u:/ in group supraglottic horizontal laryngectomy and the normal gruop.The former was significantly higher.Conclusion Close relationships were noted in the different surgery methods and the voice qualities after partial laryngectomy.The voice functions of horizontal partial laryngectomy were the best while vertical partial laryngectomy the worst.The acoustic analysis can be used to assess the postoperative voice quality,and the data can guide the rehabilitation and training in terms of the improvement of their quality of life(QOL) after surgery.

OBJECTIVE To analyze the voice and electroglottography(EGG)parameters in patients with vocal cord polyps and laryngeal cancer and to assess the voice parametric characteristics of laryngeal diseases.METHODS The computer multimedia program of Dr.Speech Science for Windows was used to obtain the voice analysis and EGG parameters in healthy adults and patients with vocal cord polyps and laryngeal cancer.The acoustic features of vocal cord polyps and laryngeal cancer were analyzed.RESULTS 1.The jitter,shimmer and NNE of voice and EGG were valuable in the objective differentiation of laryngeal diseases.2.The jitter,shimmer,and NNE values in patients with vocal cord polyps and laryngeal carcinoma were obviously higher than those in normal controls(P

Objective To investigate the factors that may affect the prognosis of patients with moderate-advanced hepatocellular carcinoma (HCC) who are receiving sorafonib therapy.Methods The clinical data of 38 HCC patients,whose diagnoses were confirmed by pathology or clinical imaging and were in accord with the Barcelona Clinic Liver Cancer (BCLC) staging criteria,were retrospectively analyzed.Sorafenib 400 mg was orally given twice everyday,and according to modified RECIST criteria the tumor response was evaluated once every 4-6 weeks,the adverse events were recorded,and the drug toxicity was evaluated by grading standard 3.0 edition for common adverse reactions formulated by American National Cancer Institute.Results Among the 38 patients,one patient developed hepatic encephalopathy after took sorafenib for two weeks,and medication had to be stopped.Of other 37 patients,14 patients developed pancreatic atrophy in different degrees (positive group),the median progression free survival (mPFS) was 9.0 months,and the median overall survival (mOS) was 25.8 months;pancreatic atrophy didn't occurred in the remaining 23 patients (negative group),the mPFS was 3.3 months,and the mOS was 8.4 months.The differences in mPFS and in mOS between the two groups were statistically significant (P＜0.01 and P=0.025respectively).The main adverse events included hand-foot skin reaction,diarrhea,fatigue and weight loss,which were relieved after symptomatic treatment,and no severe untoward effect occurred.Conclusion Certain correlation exists between pancreatic atrophy and the curative effect of sorafenib.For patients who develop severe diarrhea associated with pancreatic atrophy,a longer survival time as well as a longer stable state of disease can be expected.(J Intervent Radiol,2017,26:258-262)

Objective To explore the effect of competency-based education on course of Traditional Chinese Rehabilitation Therapy.Methods 2 sophomore classes of rehabilitation technology were as the control group and the reform group. The control group was taught with traditional model, while the reform group were taught with the competency-based education. The achievement of these groups were compared. Results There was not significant difference in the theoretical test, but was in the skill test and questionnaire score between the groups (P<0.05). Conclusion The competency-based education can improve the performance of students studying Traditional Chinese Rehabilitation Therapy.

After the contents and characteristics of SCI-covered papers list database in Dalian Medical University were described, it was pointed out that databases in academic library should provide more contents and links for the users to browse information and to use related resources by making full use of network technology. Technology and manpower should be well prepared and librarians should be qualified with patience and painstaking if an excellent SCI-covered papers list database is to be developed.

Objective To study the effectiveness of postoperative radiotherapy and prognostic factors of soft tissue sarcoma. Methods Sixty-four soft tissue sarcoma patients admitted from June 1987 to May 1997 were treated by complete,partial or extended resection and postoperative external beam radiotherapy. Fourty-eight patients received 1.8～2.0?Gy/fraction,5 f/w, to a dose of 40～72?Gy (median 60?Gy). Sixteen patients received 1.2～1.5?Gy/f, bid, 6 hr interval to a dose of 64.8～85.0?Gy (median 66.5?Gy). The 5-year survival and locoregional control rates were estimated by Kaplan-Meier method. Logrank test and Cox regression were used to study the significance of predictive factors. Results The overall 5-year survival and locoregional control rates were 60.2%, 57.9% respectively. Those of the conventional group and hyperfractionated group were 54.3% and 61.9% vs 64.3% and 42.9% ,respectively. Cox regression analysis showed that histologic grade, size and site of the primary tumor, fractionation of radiotherapy were independent prognostic factors for survival. Conclusions Complete or extended resection followed by radiotherapy are satisfactory for soft tissue sarcoma. Histologic grade , size, site of the primary tumor and method of fractionation were prognostic factors.

Objective To compare the effects of general anesthesia versus combined epidural?general anesthesia on postoperative complications in the patients undergoing thoracic surgery. Methods Two hundred twenty?one patients of both sexes, aged 18-80 yr, weighing 36-100 kg, of American Society of Anesthesiologists physical status Ⅰ?Ⅲ, scheduled for elective thoracic surgery, were randomly divided into either combined epidural?general anesthesia group ( group GE, n=112) or general anesthesia group ( group GA, n=109) . The patients were further allocated to high?risk population and low?risk population. Anesthesia was induced with target?controlled infusion of remifentanil and iv injection of propofol, sufentanil and rocuronium. A double?lumen endotracheal tube was placed, and the patients were mechanically ventilated. Partial pressure of end?tidal CO2 was maintained at 30-40 mmHg. Anesthesia was maintained with inhalation of 1% sevoflurane, target?controlled infusion of remifentanil, iv infusion of propofol, and intermittent iv boluses of sufentanil. 2% lidocaine 4 ml∕h was infused epidurally in group GE, and normal saline 4 ml∕h was given in group GA. Bispectral index value was maintained at 40-60 during surgery. Patient?controlled epidural analgesia ( PCEA ) was performed after surgery. PCEA solution contained
0.125% ropivacaine and sufentanil 0.5μg∕ml ( in 250 ml of normal saline) . The PCEA pump was set up to deliver a 2 ml bolus dose with a 20?min lockout interval and background infusion at 4 ml∕h, and visual analogue scale ( VAS) score was maintained less than 4. When VAS score ≥ 5, sufentanil 5 μg was injected intravenously as the rescue analgesic. The requirement for rescue analgesics after surgery, length of hospital stay after surgery, complications during postsurgical hospital stay ( cardiovascular events, cardiac insufficiency, acute coronary syndrome, pulmonary infection, stroke, transient cerebral ischemic attack) , and death within 30 days after surgery were recorded. Results Compared with group GE, the incidence of postsurgical cardiovascular events and atrial fibrillation was significantly decreased in group GA ( P<0.05) . In the high?risk population, compared with group GE, the length of hospital stay after surgery was significantly shortened, and the incidence of postsurgical atrial fibrillation was decreased in group GA ( P<0.05) . In the low?risk population, compared with group GE, the length of hospital stay after surgery was significantly shortened (P<0.05), and no significant change was found in the incidence of postsurgical complications, requirement for rescue analgesics after surgery, and fatality rate in group GA (P>0.05). Conclusion Compared with combined epidural?general anesthesia, general anesthesia alone provides lower occurrence of postsurgical complications for the patients undergoing thoracic surgery, and offers advantage for the high?risk patients having underlying diseases before surgery.

Objective To assess the efficacy and safety of transurethral bipolar plasmakinetic resection of the prostate(TUPKRP) for the treatment of benign prostatic hyperplasia(BPH).Methods The operation was completed using a bipolar plasmakinetic resection system(CIRCON ACMI).Three trenches were created at 5,7,and 12 o'clock position,respectively,to divide the middle,left,and right lobes of the prostate gland for resection.The bladder neck was widened in overlapping vaporizing swathes to create a wide-necked funnel down to the level of the surgical capsule.The apical tissue was resected to the anterior border of the seminal colliculus.With a F_(20) or F_(22) three-cavity catheter indwelling for 3~5 d,normal saline irrigation was used for 1~2 d postoperatively.Results The duration of the procedure was 20~180 min(53.2?28.7 min),and resected tissue weighed 8~130 g(23.5?21.6 g).The intraoperative blood loss was 10~300 ml(65.4?46.8 ml) and no blood transfusion was required.No perforation of the prostatic capsule or transurethral resection syndrome occurred.The peak urinary flow rate(Qmax) increased from 8.4?1.9 ml/s preoperatively to 18.4?1.8 ml/s 1 month postoperatively(q=55.498,P﹤0.05).The residual urine(RU) decreased from 80.8?59.7 ml preoperatively to 19.5?10.0 ml postoperatively(q=17.287,P﹤0.05). The international prostate symptom score(IPSS) decreased from 25.7?5.5 preoperatively to 5.7?2.4 postoperatively(q=52.969,P﹤0.05).The scores of quality of life(QOL) decreased from 4.4?1.0 preoperatively to 1.1?0.2 postoperatively(q=42.146,P﹤0.05). Conclusions Transurethral bipolar plasmakinetic resection of the prostate for the treatment of benign prostatic hyperplasia is effective and safe,with few complications.
