Objective To evaluate the feasibility of CT staging for esophageal cancer. Methods A retrospective analysis of 304 patients treated,from Jan. 1996 to Dec. 1998 chiefly with radiotherapy(126 conventional radiotherapy,55-65 Gy/27-35 fx/5.5-7.0 w;178 late-course accelerated hyperfractionated radiotherapy ,55-60 Gy/33-36 fx/ 4.5 -5.5 w)complete with CT data before treatment was done. The long survival was compared with pre-therapy CT findings and CT staging. ResultsThe survival rate of stage T1+T2 was very significantly different from those lesion with stage T3,T4(? 2=12.90,P0.05).The survival rates of patients positive for lymph nodes or distant metastasis were lower. Conclusion CT staging is quite optimal for non-operable esophageal cancer in clinical staging,as it is conducive to predict the prognosis.

Emotion recognition will be prosperious in multifarious applications, like distance education, healthcare, and human-computer interactions, etc. Emotions can be recognized from the behavior signals such as speech, facial expressions, gestures or the physiological signals such as electroencephalogram and electrocardiogram. Contrast to other methods, the physiological signals based emotion recognition can achieve more objective and effective results because it is almost impossible to be disguised. This paper introduces recent advancements in emotion research using physiological signals, specified to its emotion model, elicitation stimuli, feature extraction and classification methods. Finally the paper also discusses some research challenges and future developments.

BACKGROUND:The region around the hip is a bone tumor predilection site. It is difficult to conduct tumor resection due to the involvement of weight loading area. Tumor resection requires high surgical technique. The pelvis and hip are often needed to be rebuilt.
OBJECTIVE:To compare the effects of three reconstruction methods after tumor resection around the hip.
METHODS:From January 2007 to December 2012, 20 patients with bone tumors around the hip were treated by surgery in the Zhongshan Hospital, Wuhan University, including 7 benign tumors, 13 borderline and malignant tumors. Eight patients received al ograft. Eight patients received arthroplasty. Four patients received saddle prosthesis.
RESULTS AND CONCLUSION:A total of 20 patients were fol owed up for 5 to 60 months (averagely 40 months). According to Enneking evaluation criterion, the operative outcome was evaluated as excellent in 8 cases, good in 5 cases, average in 4 cases, and poor in 3 cases. Excellent and good rate was 65%. Results suggested that after excision of bone tumors, al ograft, arthroplasty or saddle prosthesis can significantly elevate patient’s survival rate, improve patient’s living quality and is an effective therapy for treating tumors around the hip.

Objective To evaluate the relationship of peripheral blood Th17 and regulatory T (Treg) cells with disease activity in patients with systemic sclerosis (SSc).Methods This study recruited 21 patients with active SSc,24 patients with inactive SSc and 24 normal human controls with informed consent.Peripheral blood samples were obtained from these subjects.Flow cytometry was used to detect the percentages of Th17 and Treg cells in peripheral blood CD4+ cells,a fluorescence-based quantitative PCR to determine the levels of interleukin (IL)-17A,retinoid-related orphan receptor gamma t (RoRγt),forkhead box P3 (FoxP3) mRNA in peripheral blood mononuclear cells (PMBCs),and enzyme linked immunosorbent assay to measure the serum level of IL-17.Results Increased percentage of Th17 cells in peripheral blood CD4+ cells was observed in patients with active SSc compared with those with inactive SSc and normal human controls (2.34％ ± 1.19％vs.0.68％ ± 0.39％ and 0.57％ ± 0.49％,respectively,both P ＜ 0.05).No statistical difference was noted in the percentage of Treg cells in CD4+ cells or the mRNA expression levels of FoxP3 between the patients with active SSc,inactive SSc and normal human controls (all P ＞ 0.05).There was a significant increase in the mRNA expression of IL-17A,RoRγt in PBMCs and serum levels of IL-17 in patients with active SSc compared with patients with inactive SSc and normal human controls ( 11.73 ± 0.80 vs.9.77 ± 1.30 and 10.79 ± 0.74,respectively,both P ＜ 0.05; 18.48 ± 1.09 vs.15.89 ± 1.48 and 17.77 ± 1.64,respectively,both P ＜ 0.05; 53.60± 9.90 pg/ml vs.15.18 ± 3.24 pg/ml and 15.53 ± 4.12 pg/ml,respectively,both P ＜ 0.05).The percentage of Th17 cells in CD4+ cells and serum IL-17 levels were both positively correlated with disease activity in patients with active SSc (r =0.675,0.644,respectively,both P ＜ 0.05).Conclusions Th17 cells are highly proliferative in patients with active SSc,which may be closely correlated with the activity of SSc.

Objective To analyze the electrophysiological characteristics of Hirayama disease and explore their significance for its diagnosis.MethodsElectrophysiological tests were performed on 18 patients who fulfilled the clinical criteria for Hirayama disease. Sixteen were males and 2 were females. The mean age was 24.9years old ( 19-58 years), and the mean case history was 5.2 years ( 1-40 years). The Hirayama disease was clearly unilateral in 10 patients and bilateral in 3, with 5 cases suspected of being bilateral. Motor neuron conduction velocity (MCV) and sensory neuron conduction velocity (SCV) were measured in the median and ulnar nerves.Electromyograms (EMGs) of the abductor digiti minimi, abductor pollicis brevis, extensor digitorum communis,brachioradialis muscle, biceps brachii and sternocleidomastoid were recorded in all cases. The MCV and SCV of the common peroneal nerve and an EMG of the tibialis anterior muscle were examined in one leg. The MCV and SCV of the ulnar nerve and EMGs of the abductor digiti minimi, extensor digitorum communis and brachioradialis muscles were inspected on the contralateral sides of 8 cases, including the patients suspected of suffering bilateral Hirayama disease. The MCVs of the median and ulnar nerves were examined segmentally by stimulating the nerves distally as well as proximally, and recording the amplitude, duration and area of compound muscle action potentials (CMAP) and changes in wave form, then determining whether there was a nerve conduction block.Results (1) No conduction block was detected in any median nerve or ulnar nerve among the 18 cases. (2) All the SCVs and sensory nerve action potentials of the median and ulnar nerves were normal. ( 3 ) All the MCVs and SCVs of the common peroneal nerve and the EMGs of the anterior tibialis muscles were normal. (4) MCV slowing in the upper limbs accounted for 41.3％ (19/44) of the examined nerves. The rates of MCV decrease were 72.2％ (13/18)in the ulnar nerve on the affected sides, 33.3％ (6/18) in the median nerve on the affected sides and 0％ (0/8)in the ulnar nerve on the contralateral sides. (5) Amplitude reduction in the CMAP in the upper limbs accounted for 81.8％ (36/44) of the examined nerves. The rates of amplitude decrease were 100％ (18/18) in the ulnar nerves of the affected sides, 77.8％(14/18) of median nerves on the affected side and 50％(4/8) of ulnar nerves on the contralateral side. ( 6 ) Upper limb EMGs revealed a rate of neurogenic damage of 47.0％ ( 62/132). The EMGs decreased in 100％ (18/18) of the abductor digiti minimi and abductor pollicis brevis on the affected side, 88.9％ (16/18) of extensor digitorum communis on the affected side, 62.5％ (5/8) of the abductor digiti minimi on the contralateral side, 37.5％ (3/8) of the extensor digitorum communis on the contralateral side,5.6％ ( 1/18 ) of the brachioradialis and biceps brachii muscles on the affected sides. There was no neurogenic damage of the contralateral brachioradialis muscle or the sternocleidomastoid on the affected side.Conclusions The electrophysiological features of Hirayama disease include unilateral or bilateral neurogenic damage in the upper limbs. According to the abnormal EMGs, spinal anterior horn cells on the affected sides were injured at C7-T1. C6and above C6 were rarely involved. The electrophysiological characteristics of Hirayama disease could provide a clear basis for localization and differentiation in Hirayama disease diagnosis.

Objective To compare the effects of remifentanil infused at different rates on median effective target plasma concentration (EC50) of propofol inhibiting responses to laryngeal mask airway (LMA) insertion and determine the optimum infusion rate of remifentanil when used for fiberoptic bronchoscopy in pediatric patients.Methods Eighty-four ASA Ⅰ or Ⅱ pediatric patients,aged 7 months-3 years,scheduled for elective fiberoptic bronchoscopy,were randomly assigned into 3 groups (n =28 each):normal saline group (group C),remifentanil infused at 3 ng· kg-1 ·min-1 group (group R1) and remifentanil infused at 5 ng· kg-1 · min-1 group (group R2).Responses to LMA insertion were defined as body movement and/or bucking during insertion.The initial target plasma concentrations of propofol were 5.2,4.8 and 4.4 μg/ml in groups C,R1 and R2,respectively.The target plasma concentration of propofol was determined by up-and-down sequential allocation.Each time the target plasma concentration increased/decreased by 0.2μg/ml.EC50 and 95 ％ confidence interval of propofol blunting responses to LMA insertion were determined by probit method.Results EC50 (95 ％ confidence interval) of propofol was 5.03 (4.92-5.12) μg/ml,4.71 (4.58-4.84) μg/rnl and 4.46 (4.20-4.94) μg/ml in groups C,R1 and R2,respectively.There was no significant difference in EC50 of propofol between groups R1 and C (P ＞ 0.05).EC50 of propofol was significantly lower in group R2 than in groups C and R1 (P ＜ 0.05).Conclusion The infusion rate of remifentanil should not be lower than 5 ng· kg-1· min-1 when combined with propofol in pediatric patients undergoing fiberoptic bronchoscopy.
