ABSTRACT
OBJECTIVE@#To explore parameters which can discriminate the voice of smoke and alcohol abuse and healthy voice by contrasting the voice parameters of two groups, and to study the pathogenic mechanism of the adverse effect of smoke and alcohol abuse to voice by the change of parameters.@*METHOD@#Selecting 33 male subjects with smoke and alcohol abuse, and selecting other 33 healthy male subjects with no smoking and alcohol abuse and no ENT disease as control, randomly. Assessed by "vocal assessment", each subject was required to phonate /ae/ for 3 s, voice parameters including F0, Jitter, NNE and CQ were collected for multivariate analysis.@*RESULT@#There were significant difference between smoke and alcohol abuse group and controlled group on the voice parameters (P < 0.01). F0 of the former is significantly lower than that of the latter (P < 0.01). Jitter of the former is significantly larger than that of the latter (P < 0.01). NNE of the former is significantly larger than that of the latter. CQ of the former is significantly smaller than that of the latter (P < 0.01).@*CONCLUSION@#Smoke and alcohol abuse had the adverse effect on the human voice. Both theory and experiment analysis were useful methods of selecting sensitive parameters. F0, Jitter, NNE and CQ were effect parameters which can reflect the voice characteristic of smoke and alcohol abuse, and can be used to monitor the effect of therapy for this kind of pathological voice.

OBJECTIVE@#This research is aimed at looking for the effect acoustic parameters of voice quality through the Spearman correlation analysis between auditory-perceptual judgment of voice quality and synthesized acoustic parameters.@*METHOD@#Thirty-six vowel samples of /ae/ synthesized with six acoustic parameters (F0, Jitter, Shimmer, NNE, Spectral tilt, Formant Flutter), each parameter dimension included 25% coped ones, altogether 45 samples. Then give the serial number to each sample after their order is randomized. The sound samples were given by computer, intensity was fixed at 70dB. Eight famous ENT doctors participated in the task of auditory-perceptual judgment. Give the grades to G, R, B, resulting that there are high inherent consistency (P<0.01). Then do the Spearman correlation analysis with each acoustic parameter respectively.@*RESULT@#There are significant correlation between the auditory-perception (G, R, B) and Jitter, Shimmer and NNE (P<0.01).@*CONCLUSION@#Jitter, Shimmer and NNE are effect acoustic parameters reflecting the voice quality. Human voice is multidimensional. The combination the auditory-perceptual (G, R, B) judgment with acoustic analysis is the best method of assessing the voice quality.

@#Objective To evaluate the efficacy of comprehensive rehabilitation on cervical syndrome(CS).Methods 112 patients with CS were randomly divided into two groups.The cases in comprehensive rehabilitation group(n=56) were treated with traction,ultrashort wave and massage,while those in the control group(n=56) were treated with traction only.Results The efficient rate of comprehensive group were 91.1% 3 weeks after treatment,and the symptom scores improved significantly compared with the control group(P<0.01).Conclusion The comprehensive rehabilitation is efficient on cervical syndrome with few side-effects and complication.
ABSTRACT
Objective To investigate the CT manifestations of recto-endometriosis. Methods Three pathologically proved cases of recto-endometriosis were reported, the CT features and clinical manifestations were investigated retrospectively with review of literatures. Results The patients were all menstruating females (28, 34, and 45 years old, respectively), and anal pain emerged during menses in one case. Rectal examination revealed stiff immobile mass along the rectal wall in all three cases. All the cases showed solid masses on CT scan with moderate enhancement after contrast administration. Two of them confined to the rectal walls, another involved the rectum and peri-rectal aspect. One case was misdiagnosed as well-differentiated adenocarcinoma of rectum in frozen section by biopsy specimen.Conclusion A solid mass was always found in recto-endometriosis. No characteristic CT feature was manifested. Attention should be paid to the differentiation from rectal tumors when making the diagnosis.
ABSTRACT
PurposeTo evaluate the advantages and limits of different diagnostic imaging modalities for adrenal neuroblastoma diagnosis in children. MethodsImaging manifestations of 26 pathologically proved cases of adrenal neuroblastoma were retrospectively reviewed. Results37.5% of the cases were revealed by IVP, 82% were found by US, while 90% of the cases were demonstrated by CT. ConclusionUS should be considered as the first choice for diagnosing the adrenal neuroblastoma, while CT seems superior to US.
ABSTRACT
Objective To observe the effects of hyperbaric oxygen on treating osteoporosis pain and increasing life quality in the elderly. Methods 45 osteoporosis patients with spontaneous pain were randomly divided into two groups: the control group treated with calcium and experimental group treated with calium and hyperbaric oxygen. The two groups had not significant difference in bone mineral density before treatment.Results After twenty days treatment the pain was significantly relieved and quality of life was significantly increased in the experimental group compared with the control group (P
