Objective To investigate the changes in mechanics of respiration during perioperative period in patients undergoing orthotopic liver transplantation (OLT) without venovenous bypass. Methods Thirty patients of grade Ⅱ~Ⅲ according to the American Society of Anesthesiologists (ASA) classification, undergoing orthotopic liver transplantation without venovenous bypass, were included in this study. The respiratory parameters measured perioperatively included average airway resistance, peak inspiratory pressure, peak expiratory flow rate, dynamic compliance, work of breathing and respiratory drive. The complications of respiratory system during postoperative period were observed. Results Average airway resistance was decreased after abdominal cavity opening, decreased significantly at 5 min new hepatic phase and increased postoperatively. Peak expiratory flow rate and dynamic compliance were increased gradually after induction and increased significantly at anhepatic phase and new hepatic phase but decreased significantly on the first day postoperatively. Work of breathing was decreased after induction and decreased significantly at anhepatic phase and postoperative period. There was no significant difference in peak inspiratory pressure during operation. Compared with the values preoperation, the respiratory drive was decreased significantly during anhepatic phase and new hepatic phase. Total 35 times of postoperative respiratory complications occurred, which included pleural effusion, atelectasis, pulmonary artery hypertension, pulmonary interstitial edema and pnermonia. Conclusions There are obvious changes in respiratory mechanics during perioperative period of OLT, especially in postoperative period. Mechanical respiratory support is essential for patients until respiratory function recovers.

To improve and optimize marine antimicrobial peptide R-1 production by a newly isolated Brevibacillus laterosporus Lh-1, Plackett-Burman (PB) design and response surface methodology (RSM) using central composite design was adopted in culture conditions. MINITAB 15.0 was used for planning the experiments, data analysis, contour diagrams and response optimizations. In this study, PB design was undertaken to evaluate the effects of the fifteen factors. By the statistical regression analysis, the significant factors affecting the novel antimicrobial peptide R-1 in submerged fermentation by Br. laterosporus Lh-1 were determined as follows: glucose, peptone and CaCl2. Then a RSM was used to optimize the above critical internal factors, and the optical concentration of the variables were deter-mined as: 15.72 g/L glucose, 6.01 g/L peptone and 3.29 g/L CaCl2. The content of R-1 was increased from 82.15 kU/mL to 116.27 kU/mL.

Objective To investigate the intelligence level and characters in children with cerebral palsy of 4~6 years old, and the factors related with their intelligence. Methods 215 cerebral palsy children of 4~6 years old were assessed with Wechsler Intelligence Scale for children,Gross Motor Function Classification System (GMFCS). Results 210 children finished their intelligence test, and 113 presented mental retardation. The intelligence level was higher in the children with spastic diaplegia, hemiplegia and dyskinetic type than those with quadriplegia and ataxia type. The difference was significant between VIQ and PIQ in the spastic diplegia (P<0.05). The mental retardation was more frequent in the children with GMFCS Ⅳ~Ⅴ, or with epilepsy or microcephaly than those with GMFCS Ⅰ~Ⅲ or without the complications (P<0.05). Conclusion The incidence of mental retardation in children with cerebral palsy was related with the neurotypes, motor function and complications.

Objective To investigate the clinical characteristics of speech disorders in children with cerebral palsy (CP) and any relationship between those characteristics and cranial magnetic resonance images.Methods A sample of 138 children with CP were given the < s-s > language development test,a Chinese-language articulation test and oral motor scores to quantify their functional speech and articulation.The characteristics of their speech disorders,articulation and oral motor dysfunction were then related with abnormalities in their cranial magnetic resonance images (MRIs).Results Of the 138 MRIs,only 9 were normal.Three showed non-specific abnormalities (delayed myelination and/or broadening of the space outside the brain) and 122 (91%) showed specific abnormalities.Among the children with specific abnormalities,51.6% had speech reception delay and 74.6% had speech expression delays.The dysarthria rate was 71.3%,including 8.7% with no speech ability at all.The main MRI abnormalities were lesions of the basal ganglia (23%),lesions of the cerebellum (11.5%),periventricular leukomalacia (PVL) (47.5%),extensive cortical or subcortical lesions (6.6%) and focal cerebral injury (11.5 %).The corresponding oral motor scores increased successively.The children with lesions of the basal ganglia or cerebellum were most likely to manifest speech expression delay and dysarthria.The children with cortical or subcortical lesions or PVL also showed speech expression delay and dysarthria.However,the children who had a focal cerebral injury generally performed well on the speech ability assessment.Twelve children had no speaking ability at all,and in 7 of them the lesions were of the basal ganglia.Conclusions The probability and severity of speech disorders in children with cerebral palsy relate with specific abnormalities detectable with cranial MRI.Those with lesions of the basal ganglia or cerebellum will be more likely to show more severe speech disorders.

Objective To study the impact of the peripheral neurotomy method combined with rehabilitation exercise on gross motor function and balance function of children with cerebral palsy.Methods Matched pair design was used in the study.Thirty children with spastic cerebral palsy hospitalized from May 2011 to Nov.2013 suffering from peripheral neurotomy were assigned as study group,who were conscious and treated by peripheral neurotomy com bined with rehabilitation exercise.In the meanwhile,30 children inpatients at the same time were employed as the control group,who were similar in age and symptoms,with the same gender and the same Gross motor function classification (GMFCS) grade,and the controls were treated only with ordinary rehabilitation exercise.Modified Ashworth score,Gross Motor Function Measure (GMFM) D and E regions scores,physicians rating scale score in the 2 groups were recorded after treatment for 2,4,6,8,10 weeks.Repeated measure analysis of variance method was introduced to analyze the differences between the 2 groups in improved Ashworth muscle tension,gait improvement,gross motor function and balance function.Results The study group was superior over the control group in muscle tension reduction (F =8.177,P =0.006) and gait improvement(F =24.284,P =0.000).The 2 groups were not different statistically in D region evaluation of GMEM (F =0.072,P =0.790) and E region evaluation of GMFM (F =0.000,P =0.985) ; For Berg balance scale,the 2 groups had also no difference(F =0.150,P =0.700).Conclusions Both peripheral neurotomy method combined with rehabilitation exercise and the ordinary rehabilitation exercise method both could improve the gross function and the balance function.Furthermore,the former was superior over the latter in muscle tension reduction and gait improvement.

Surgery to repair cheek defect has been performed for a long time but no method can be considered as the best and be universally applicable since the shape and size of cheek defect are variable and no reasonable classification is established for cheek defect.Two hundred and twenty-three cases of cheek defect were collected in a 26-year period from 1964 to 1990.According to the size and degree of the cheek defects,a classification into 5 categories and corresponding 5 repair methods were established.The total success rate war 92.83%.The clinical features of the defects,the indications of operation,and the choice of repair methods for different types of defects were discussed.It is concluded that our classification of cheek defects into 5 categories is helpful to differentiate the operative indications,to choose the suitable method of repair and to evaluate the.therapeutic efficacy.
