In order to solve the difficult problems of repair and reconstruction for severe deep burns with compound tissue defects of upper limb, 26 cases were treated with transplantation of compound tissue flap, vascularized by anastomosis of blood vessel or by vascular pedicle. Several kinds of reparative and reconstructive procedure could be performed simultaneously. Not only the tissue defect was repaired, but also the upper limb function was reconstructed in one stage operation. Owing to the presence of abundant vascular supply from the vascularized compound tissue and primarily closing the wounds, the anti-infection potency was high, then it was suitable for such conditions as fresh severe deep burn with infection and compound tissue defects. As a result, this technique provided the best chance to save upper limb from amputation. The duration required for treatment could be markedly shortened. All the cases successed. The long-term functional recovery was satisfactory. This method provided the possibility to solve effectively the difficult problem dealing with the severe deep burns with compound tissue defects of upper limb.
Developmental and epileptic encephalopathy (DEE) is a group of diseases that severely affects the neurological development of children, characterized by frequent seizures and significant neurodevelopmental impairments. These diseases not only impact the quality of life of affected children but also impose a heavy burden on families and society. In recent years, the development of brain network theory has provided a new perspective on understanding the pathological mechanisms of DEE, especially the role of structural and functional brain networks in the process of epilepsy. This review systematically summarized the research progress of structural and functional brain networks in DEE, highlighted their importance in seizure activity, disease progression, and prognosis evaluation.
Objective To explore current results after staged operations in patients with functional single ventricle anomalies and pulmonary hypertension. Methods We retrospectively analyzed the clinical data of 129 patients with functional single ventricle anomalies and pulmonary hypertension undergoing pulmonary artery banding in our hospital between April 2008 and December 2015. There were 81 males and 48 females. There were 71 patients with double outlet of right ventricle, 17 patients with tricuspid atresia, 7 patients with transposition of great arteries, 33 patients with uni-ventricular heart, and one patient with complete atrio-ventricular septal defect. The surgical results, transition to Glenn procedure and subsequent transition to Fontan procedure were analyzed. Results The 129 patients underwent 159 operations of pulmonary artery banding totally. Hospital mortality was 4.7% (6/129). Nine patients were lost to follow-up. Eighty-seven (67.4%) patients underwent the second-stage Glenn procedure, and 43 patients(33.3%) underwent third-stage Fontan procedure. Two patients died after Glenn and 3 patients died after Fontan separately. There were 32 patients who accompanied with coarctation, interruption of aortic arch, heterotaxy, total anomalous pulmonary venous connection or atrio-ventricular valve regurgitation. Fifteen (46.9%) patients succeeded in transition to Glenn, and 6 (18.8%) patients succeeded in transition to Fontan. Fourteen patients developed obstruction of left ventricular outlet tract or bulbo-ventricular foramen. Conclusion Early pulmonary artery banding is an acceptable strategy for patients with single ventricle anomalies and pulmonary hypertension. Outcomes and results of subsequent Glenn and Fontan procedures are generally good. Accompanied complex anomalies are risk factors for lower ratio of transition to Glenn and Fontan procedure.
Objective To introduce a new functional self-assessment scale of amyotrophic lateral sclerosis (ALS). Methods By comparing current different ALS functional scales and combining relative cl inical experience and numeric pain intensity scale, ALS self-assessment scale was set down by International Association of Neural Restoration. Results ALS self-assessment scale included 3 categories with 18 items, adopting 10 points grading system, namely 10 was defined as the normal, 0 as the worst, and the total scores was 180. This scale included: ① Bulbus medullae function: speech, swallowing, sal ivation, and tongue extension. ② Limbs function: left arm movement, left hand movement, right arm movement, right hand movement, left leg movement, right leg movement, trunk movement, head-up, walking, and cl imbing stairs. ③ Others: breathing, muscular tone, pain, and muscle discomfort. Conclusion ALS self-assessment scale is specifically designed for ASL patients. It can evaluate patient’s function comprehensively and is simple and convenient, consuming less time.
Objective To study the treatment method and effect of abduction and lateral rotation l imitation of the shoulder in obstetric brachial plexus palsy (OBPP). Methods From February 2005 to August 2008, 11 patients with abduction and lateral rotation l imitation of the shoulder in OBPP were treated with dissection of the origin of subscapular muscle,transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. Among them, there were 6 males and 5 females with a mean age of 6 years (1-15 years). The main cl inical manifestations showed adduction, internal rotation contracture deformity of shoulder, l imited active and passive external rotation and severely restricted active abduction of shoulder. The passive abduction was more than 90°. According to Gilbert grading, there were 7 cases of grade 1 and 4 cases of grade 2. Based on Mallet score systems, the scores were 5 points in 3 cases, 6 points in 3 cases, and 7 points in 5 cases. The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi all reached 3-4 grades. Results One patient developed postoperative hematoma, wound healed after symptomatic management. Other patients achieved incision heal ing by first intention. All patients were followed up for 12 to 37 months (17 months on average). The active abduction and external rotation of the shoulder joints recovered obviously. The Gilbert grading were grade 2 in 1 case, grade 3 in 1 case, and grade 4 in 9 cases; the Mallet scores were 10 points in 1 case, 11 points in 2 cases, 12 points in 4 cases, 13 points in 3 cases, and 14 points in 1 case; showing significant differences when compared with those before operation(P lt; 0.01). The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi increased to 4-5 grades. Conclusion The dissection of the origin of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles can resolve shoulder adduction, internal rotation contracture, and can enhance abduction, external rotation strength. It is an effective operation for abduction and lateral rotation l imitation of the shoulder in OBPP.
Esophageal reconstruction with interposition of transverse colon was performed in 24 children from 1971 to 1992. The results were evaluated from questionaire, clinical interview, barium swallowing, manometric and radioisotopic test. The complications and the functional status of the gastrointestinal tract were studied and discussed. The follow up showed the growth and developmenlt of the children were satisfactory, the results were good to excellent in 89.5 per cent. If necessary, pyloromyotomy should be chosen instead of other methods of pyloroplasty. Compairing the three routes of colon reconstruction, the esophageal bed route had an excellent clinical result.
ObjectiveTo evaluate the differences of visual evoked potentials (amplitudes and latency) between cerebral palsy (CP) children and normal children. MethodsThis study involved fourteen children aged from 4 to 7 years with CP (monoplegia) between 2009 and 2013. Another 14 normal children aged from 5 to 9 years treated in the Department of Ophthalmology in West China Hospital during the same period were regarded as the control group. Both eyes of all the participants were examined by multifocal visual evoked potential (mfVEP). The mfVEP examination results were recorded, and amplitude and latency were analyzed. First, we analyzed the differences of amplitudes and latency time between monoplegia children and children in the control group. Second, gross motor function classification system (GMFCS) was used to classify the fourteen monoplegia children among whom there were five GMFCS Ⅰ patients and nine GMFCS Ⅱ patients. The differences of mfVEP were analyzed between the two GMFCS groups. ResultsThe amplitude and latency of mfVEP in children with CP showed gradual changes similar to those in the normal children. The amplitudes were decreasing and the latencies were delaying from the first eccentricity to the sixth eccentricity. The amplitudes in children with CP were lower than those in the control group in the first to the third eccentricities for both eyes (P＜0.05), and latency of left eye was delayed in the first eccentricity in children with CP (P=0.045). No difference was found between the two GMFCS groups (P>0.05) except the amplitude of the first eccentricity (P=0.043). ConclusionsThe results of mfVEP show significant differences of amplitude and latency between CP and normal children, suggesting the existence of visual pathway impairments in cerebral palsy children. The results of mfVEP can provide an objective basis of visual impairments for cerebral palsy children.
Twelve cases (13 hips) of congenital dislocation of hip (CDH)in a group above the age of six were treated by Chiari pelvic osteotomy from Jan. 1991 to Dec. 1992. The results following operative treatment rated as good in 85 percents according to the clinical and radiologic examinations. The indications, and the results with the operation as the functional reconstuction of the hip concerned were discussed.
The research shows that personality assessment can be achieved by regression model based on electroencephalogram (EEG). Most of existing researches use event-related potential or power spectral density for personality assessment, which can only represent the brain information of a single region. But some research shows that human cognition is more dependent on the interaction of brain regions. In addition, due to the distribution difference of EEG features among subjects, the trained regression model can not get accurate results of cross subject personality assessment. In order to solve the problem, this research proposes a personality assessment method based on EEG functional connectivity and domain adaption. This research collected EEG data from 45 normal people under different emotional pictures (positive, negative and neutral). Firstly, the coherence of 59 channels in 5 frequency bands was taken as the original feature set. Then the feature-based domain adaptation was used to map the feature to a new feature space. It can reduce the distribution difference between training and test set in the new feature space, so as to reduce the distribution difference between subjects. Finally, the support vector regression model was trained and tested based on the transformed feature set by leave-one-out cross-validation. What’s more, this paper compared the methods used in previous researches. The results showed that the method proposed in this paper improved the performance of regression model and obtained better personality assessment results. This research provides a new method for personality assessment.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder.
