ObjectiveTo study the effects of the Behavior Therapy on outpatient with schizophrenics in relieving symptoms, insight, and attitude to treatment. Methods96 outpatients with schizophrenia were randomly assigned to the Behavior Therapy group and the control group. The Behavior Therapy courses were given to the Behavior Therapy group for six months. All the subjects were evaluated with Positive and Negative Syndrome Scale(PANSS) and Insight and Therapeutic Attitude questionaire(ITAQ). Results94 cases completed the trial. The scores of PANSS, the Negative Subscale, the General Psychopathology Subscale of the Behavior Therapy group decreased significantly after treatment(P<0.01). The score of ITAQ of the Behavior Therapy group increased significantly after treatment(P<0.01).The reductions of PANSS, the Positive Subscale, the Negative Subscale, the General Psychopathology Subscale and ITAQ between two groups were significant different(P<0.05-P<0.01). Conclusions The Behavior Therapy may play an important role in augmenting optimal pharmacotherapy for outpatients with schizophrenia and it is effective in improving symptoms, insight and therapeutic attitude.

OBJECTIVETo analyze the current status of maternal HIV infection, mother to child transmission, and the work accomplishments in preventing mother-to-child transmission of HIV (PMTCT).

METHODSDuring October, 2001 to May, 2009, HIV voluntary consultation and examination were carried out in 339 866 pregnant women in the urban areas, while 594 pregnant women who tested positive were intervened, and interventions were also conducted among 326 babies who were born to HIV positive mothers, including HIV immune body examination on the babies when they were 12 months and 18 months old.

RESULTSA total of 594 pregnant women were found HIV positive, with the positive rate of 0.17% (594/339 866). And the rate was declining year by year. The highest rate was 0.47% (37/7837) in 2002, and the lowest rate was 0.12% (86/73 343) in 2008. Of the 594 positive pregnant women, 228 (38.38%) terminated pregnancy voluntarily, 43 (7.24%) kept on pregnancy and 317 (53.37%) parturients. Of 326 babies born by the 317 parturients, 317 survived.298 received curbing intervention for mother to child transmission (PMTCT), the ratio was 94.01% (298/317). Of 224 babies who were 18 months old, 221 accepted examination, and 7 HIV positive. The maternal infant transmission rate after intervention was 3.17% (7/221).

CONCLUSIONThrough the prevention of mother-to-child transmission of HIV, the HIV infection status in the pregnant women can be timely observed, which can effectively decrease the level of mother-to-child transmission of HIV.

OBJECTIVETo investigate the three-dimensional reconstruction methods of the portal vein using 64-slice spiral CT data and the anatomical variation of the portal vein.

METHODSThree-dimensional reconstruction of the portal vein was performed using Mimics software based on the 64-slice spiral CT data of 64 cases. Each model of the portal vein and its branches was evaluated according to the presentation rate, depiction quality and anatomic variation.

RESULTSThe reconstructed model showed a depiction rates of 100% for the 4-grade branches of the portal vein. The stem of the portal vein and the left and right branches of the level III or above were all displayed, but in 2 cases the superior mesenteric vein and in 1 case the spleen vein was displayed only to the level IV. Of the 64 cases, 50 (78.1%) had normal portal vein and 14 (21.9%) showed anatomical variations.

CONCLUSIONThe 3D model vividly mimics the anatomic variations of the portal vein to provide valuable information for surgical plans.

OBJECTIVETo retrospectively analyses the results of dynamic axial external fixator with modified technique in the treatment of severely Pilon fractures.

METHODSFrom July 2000 to February 2003, 14 patients with severely Pilon fractures were treated with dynamic axial external fixator inserted with modified technique combined with limited open reduction and internal fixation with screws and Kirschner wires, with two distal external pins inserted into talus and calcaneus respectively so that the rotation axis of distal clamp was coincided with that of ankle joint. All patients were young or middle-aged people from 20 y to 52 y (average 38 y). All fractures were Rüedi-Allg were type II or type III. External fixators were removed after bone healing. Duration of follow-up was 5 - 36 m (average 18 m).

RESULTSThe time of bone healing was 12 - 24 weeks (average 14 weeks). At the latest follow-up, results include 5 excellent, 6 good and 3 fair according to ankle scoring system (ASS). There was only one case of superficial pin site infection settled with oral antibiotics and pin site care with mild disinfectants. There was no wound breakdown, superficial and deep infection, osteomyelitis, fracture fragments redisplacement and collapse.

CONCLUSIONDynamic axial external fixator with modified technique combined with limited internal fixation is an effective method for the treatment of severely Pilon fractures.

Objective To explore the factors that influence the stability of evaluation results judged by a jury through a standard research on perceptual evaluation measurements of voice quality. Methods Voice samples from 300 patients with dysphonia and 100 control subjects with normal voice were recorded and assessed by a jury composed of 6 experienced listeners from different hospitals. The voice samples were discourse voices and ordered randomly 3 times, and the mean of 3 evaluations using visual analogue scale were the final results. The jury was instructed to classify voice samples according to the G ( grade) , R (rough) and B(breathy) components of the GRBAS scale on a 4-point scale ranging from 0 for normal to 3 for severe dysphonia. K value was used to analyze the concordance of evaluation results and regression analysis was used to research the effects of the extent of voice disorder to the stability of perceptual evaluation. Results The discordance of evaluation existed both between the jury and in listeners themselves. The concordance of listeners themselves of each evaluation parameter was not bad, good, or even very good, and the concordance of evaluation of G was the best (κ value: 0. 46 - 0. 85) , then R (κ value; 0.41 -0.84) and B(κ value: 0.41 -0.81). The concordance between the jury was worse than that in themselves. And except a listener whose concordance of evaluation was under the requirement, the concordance of evaluation of G was the best ( κ value: 0. 43 - 0. 96) , then R ( κ value: 0. 33 - 0. 78 ) and B ( κ value: 0. 002 - 0. 45 ). The stability of evaluation of normal voice and severe voice disorder was better than mild and moderate voice disorder. Conclusions The discordance between the jury was the main factor that influence the stability of perceptual evaluation. The evaluation parameters and extent of voice disorder will influence the stability of perceptual evaluation of the jury.

OBJECTIVETo study the behaviors of normal recurrent laryngeal nerve and superior laryngeal nerve evoked electromyography, to know the reference values of related parameters.

METHODSThirty six normal subjects were studied with laryngeal evoked electromyography. The latent period, duration, and amplitude of the evoked potentials (EP) recorded in laryngeal muscles were investigated.

RESULTSThe latent period of the EP recording from the thyroarytenoid muscles (TA), after stimulating recurrent laryngeal nerve (RLN), was (1.13 - 2.25) ms (x +/- 2s), that of TA after stimulating vagus nerve (VN) was (2.57 - 5.85) ms. There were significant differences in the latent periods of EP between RLN and VN (P < 0.01), and the latent periods of EP recording from TA after stimulating right cervical part of VN, (2.01 - 4. 53) ms (x +/- 2s) were significant shorter than those of left, (3.70 - 6.98) ms (x +/- 2s, P < 0.01). The durations of the EP were somewhat different but not significant. The amplitudes of the EP in different laryngeal muscles changes markedly. The wave form and latent period of the EP recording from cricothyroid muscle (CT), after stimulating the external branch of superior laryngeal nerve (SLN), was similar with the EP of RLN, the reflective EP R1 and R2 could be recorded from TA, posterior cricoarytenoid muscles (PCA), CT after stimulating the internal branch of SLN.

CONCLUSIONSThe characteristics of the EP recorded in laryngeal muscles after stimulation of RLN, SLN and VN are different. The latent period, duration and amplitude are important parameters in the evaluation of laryngeal nerves function, the latent period is the most important parameter.

OBJECTIVETo observe the laryngopharynx manifestation and electromyography characteristics of myasthenia gravis (MG) patients.

METHODSThirty cases of MG were included in this study, their laryngopharynx symptoms and signs, voice acoustic assessment, laryngeal electromyography (LEMG) behaviors and repetitive nerve stimulation test(RNS) were analyzed, and the data was compared with that of normal subjects.

RESULTSAbout 36.7% of MG patients (11/30) had the symptoms of hoarseness, voice fatigue, dysphonia and dysphagia. The vocal folds movements of 16.7% of MG patients(5/30) appeared weaker than normal, and their vocal glottic couldn't close completely, while with a seam during phonation. Voice amplitude (68.3 +/- 14.6) dB (x +/- s, same at below), and maximum phonation time (15.1 +/- 4.0) s, were greatly lower than normal; shimmer(2. 43 +/- 1.19)%, and normalized noise energy (-9.6 +/- 3.3) dB, were greatly higher than normal. The amplitudes of interference patterns in MG patients' LEMG markedly decreased, except introarytenoid muscle, during low, normal and high pitch phonation, the amplitudes of thyoiarytenoid muscle were (215 +/- 69) microV, (298 +/- 113) microV and (380 +/- 153) microV, those of cricoarytenoid muscle were (253 +/- 92) microV, (361 +/- 116) microV and (486 +/- 155) RV. The turns increased but had no statistical difference. In the RNS test, 83.3% MG patients (25/30) showed masculine response. There were about 2.20 +/- 1.32 pieces of laryngeal muscles involved, and the reduction rate in amplitude of the compound muscle action potential for RNS was about (27.9 +/- 19.2)%.

CONCLUSIONSOnly parts of MG patients had laryngopharyngeal symptoms, but the laryngeal muscles of most of them were involved, appearing as the masculine response for RNS, the decreased synchronization of the laryngeal muscles' interference patterns, the decreased capacity of phonation. MG must be differentiated when a patient has the symptoms of voice weakness, hoarseness and dysphonia. Laryngeal RNS test should be used in the early diagnosis of MG.
