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 investigate the chemical constituents in the aerial parts of mangrove plant Avicennia marina. Methods The isolated compounds Ⅰ-Ⅹ were obtained by the combination of silica gel, Sephadex LH-20 column chromatographies and by semi-preparative HPLC separation. Structural elucidation was conducted by the modern spectral method. Results Ten compounds were isolated and identified from the aerial parts of A. marina, including acteoside (Ⅰ), isoacteoside (Ⅱ), syringaresinol (Ⅲ), 5, 7-dihydroxy-3′, 4′, 5′-trimethoxyflavone (Ⅳ), indolyl-3-carboxylic acid (Ⅴ), betulinic acid (Ⅵ), betullin (Ⅶ), lupeol (Ⅷ), avicequinone C (Ⅸ), and kaempferol (Ⅹ). Conclusion Compounds Ⅰ-Ⅵ are isolated from A. marina for the first time.

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 observe influence of salmeterol xinafoate and fluticasone propionate powder applied in asthmatic exacerbated period on relieving efficacy of a fast-acting beta2-agonist.Methods Eighty-nine children with asthma in exacerbated period were randomly assigned into two groups.Thirty-nine cases in treatment group inhaled salmeterol xinafoate and fluticasone propionate powder, compared with 50 cases in control group treated with budesonide aerosol. Two groups were all given Bricanyl aerolised inhalation in same way at meanwhile.Results The improvement of peak expinatory flow in two groups was evident. The disappearing time of main symptoms and signs, the duration of staying in hospital of two groups were no difference (all P
