Objective To explore the therapeutic methods and effects of orbital blow-out fractures.Methods Thirty-three cases (36 eyes) of orbital pure blow-out fracture were treated by surgery from January 2007 to July 2013.The features of orbital fractures were determined with three-dimensional computed tomography scans.The area of fractures was exposed through sub-ciliary incision,the herniated orbital contents were released and reduced to the orbital cavity.The fractured orbital walls were repaired precisely with autologous bone or Medpor.Results After 6 to 12 months followup,there were no serious complications such as infection of bone graft,exposure of implants in all 33 cases,and all the cases got satisfactory appearance of eyelids and orbit,of which the diplopia disappeared and eyeball movement function recovered normally.The protrution of eyeball in 29 cases were symmetrical,but 4 cases presented mild enophthalmos at affected side.Conclusions The orbital volume enlarges and orbital content herniating into paranasal sinuses is caused by orbital blow-out fracture.Implanting autogenous grafts and Medpor to restore orbital volume are proved to be effective.Early CT examination is an effective method for the diagnosis.In order to avoid complications,the orbital blow-out fracture should be subjected to surgical treatment as soon as possible.

Objective To investigate the application of nasal jejunal tube and nasogastric tube of two different catheter ways in improving the severe craniocerebral injury and the low temperature condition and the role of early enteral nutrition support and compare the difference between its curative effect.Methods A total of 120 patients with severe craniocerebral injury underwent normal and low temperature treatment were selected,and they were divided into nasal jejunal tube enteral nutrition(nasal jejunal tube group,60 cases)and nasogastric tube enteral nutrition(nasogastric tube group,60 cases)by simple random sampling.After implement nasogastric tube and nasal jejunal tube,normal pressure using enteral nutrition elemental diet and/or enteral nutrition multi polymerization agent produced the best nutrient solution implementation of early enteral nutrition support,two groups of subjects under the condition of bowel function exists,within 48 h starting enteral nutrition,compared two groups of various nutrition indicators as well as adverse reactions and complications,and Glasgow Coma Scale(GCS)score,Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ)score,etc.Results The patients with severe craniocerebral injury after early nutrition,the various nutrition indicators had improved in two groups.The rise extent of triceps skinfold thickness,arm muscle circumference,serum albumin,prealbumin,transferrin,hemoglobin and other indicators in nasal jejunal tube group was higher than that in nasogastric tube group on the 14th,28th day after admission,and there was significant difference(P ＜ 0.05).The incidence of diarrhea,bloating,vomiting,and stomach contents reflux retention in nasal jejunal tube group was lower than that in nasogastric tube group [5.0％(3/60)vs.18.3％(11/60),10.0％(6/60)vs.21.7％(13/60),5.0％(3/60)vs.21.7％(13/60),15.0％(9/60)vs.16.7％(10/60),11.7％(7/60)vs.48.3％(29/60),8.3％(5/60)vs.21.7％(13/60)],and there was significant difference(P ＜ 0.05).The incidence of complications in nasal jejunal tube group was lower than that in nasogastric tube group [16.7％(10/60)vs.76.7％(46/60)],and there was significant difference(P ＜0.05).The changes of GCS score,APACHE score in nasal jejunal tube group was more obvious than that in nasogastric tube group,and there was significant difference(P ＜ 0.05).Conclusions Early nasal jejunal tube enteral nutrition for the severe craniocerebral injury after the low temperature condition in clinical enteral nutrition implementation is feasible and reasonable,compared with a nasogastric tube feeding,can obviously reduce the complications of enteral nutrition and reach goals earlier nutritional therapy,can improve the prognosis.

AIM: To construct a genomic regulatory network based on gene expression profiling of hypertrophic cardiomyocytes induced by phenylephrine in neonatal rats. METHODS: Cultured neonatal hypertrophic cardiomyocytes were induced by phenylephedrine. The gene expression profiles of these cells were assessed by using a cDNA microarray, and the microarray data were further analyzed by Pathwaystudio and Agilent Literature Search software. RESULTS: A genes/proteins interaction network was constructed with 450 nodes and 592 edges by analyzing the gene expression in hypertrophic cardiomyocytes and literature mining. The network belongs to scale - free network by topological analysis, and 14 genes/proteins as key nodes, including PTPN11, TRAF6, HSPA8, VIM, RPS6KA3, PTHRP, GRB2 and PI3K, were predicted. Based on GO analysis, the genes/proteins associated with metabolism, signal transduction and cytoskeleton may play important roles in the process of cardiomyocytes hypertrophy induced by phenylephedrine in neonatal rat. CONCLUSION : The genomic regulatory network based on gene expression profiling and literature mining may provide integrated clue to elaborate hypotheses about the evolution of cardiomyocyte hypertrophy.

A simple,reliable RPHPLC method on ODS column with UV detector for deter-mination of the anticoagulant rodenticide coumatetralyl in animal tissue was developed.1,1′-Bi-(2-Naphthol)was used as an internal standard to check the process ofexperiments.The mean recoveries from the spiked rabbit liver were around 90% atthe levels of 0.4-16mg/kg.The coeffecint of variation of 5 determination was 3.2%.The results showed that this method has a satisfactory reproducibility.The methodis practical for examining poisons in poisoning cases.

Nine Rabbits were orally administrated with a single dose of 25mg/kg,100mg/kgcoumatetralyl to establish poisoning model.Poisoning sympton and pathological changes were observed.Coumatetralyl content in main internal organsand muscle was determined by RPHPLC method.The results were discussed.

Impact of air pollution on cardiovascular d is eases has been established. As the main source of city air pollution, particulat e matter has been demonstrated an independent correlation with incidence and mor tality of cardiovascular diseases. The mechanisms are not clear. Several plausib le mechanistic pathways have been described, including inflammation induced by o xidative stress, the followed enhanced coagulation/thrombosis resulted in instab ility of atherosclerosis, the promotion of ischemic heart diseases and imbalance of autonomic nerve tone resulted in the occurrence of arrhythmia. The article p rovides a review of the mechanisms on air pollution and cardiovascular diseases and suggestions for further research.

METHODS: Volume overload-induced cardiac hypertrophy was established by abdominal aortacaval fistula (ACF) and pressure overload-induced cardiac hypertrophy was developed by constriction of aorta (CA). The cardiac structure and function were analyzed by echocardiography, hemodynamic determination, heart weight measurement and histological examination. RESULTS: Heart weight of rats in all the operated groups was increased compared to the sham-operated groups. In 1-week ACF group, the internal diameter (0.67?0.03)cm vs (0.60?0.02)cm, P

Objective To observe the effect of homemade ankle-foot orthopedic band on motor function of lower extremities in children with foot drop post spastic hemiplegic cerebral palsy (CP). Methods 24 spastic hemiplegic CP children were randomly divided into observation group (n=12) and control group (n=12). Both groups accepted roution rehabilitation training. The control group accepted walking training, and the observation group accepted walking training wearing the homemade ankle-foot orthopedic band, for 12 weeks. They were assessed with modified Ashworth Scale (MAS) of gastrocnemius, range of motion (ROM) of ankle active dorsiflexion, and D and E domains of Gross Motor Function Measure (GMFM-88) before and after treatment. Results The score of MAS significantly decreased in both groups after treatment (P<0.01), and decreased more in the observation group than in the control group (P<0.05). ROM and scores of D and E domains of GMFM-88 significantly increased in both groups after treatment (P<0.01), and increased more in the observation group than in the control group (P<0.05). Conclusion Walking training with the homemade ankle-foot orthopedic band may further decrease the muscle tone of gastrocnemius, increase the active range of motion of ankle and improve the motor function of lower extremities in children with foot drop post spastic hemiplegic CP.
