Because of spine structure and location importantance, spine artificial surgery is not only high-risk but also require proficiency of doctors. Image navigation system for spinal surgery could reduce risk and postoperative complications, and spinal image segmentation and registration methods are the key steps. This paper summarized spinal image segmentation and registration methods. Based on analysis of existing methods, we pointed out the shortcoming in the field, thus forecasts future development.

Due to substantial morbidity and high complications, diabetes mellitus is considered as the third "killer" in the world. Medicinal fungal polysaccharides, as water-soluble macromolecular substances with low toxicity, exhibit diversified pharmacological actions such as immune regulation, anti-tumor, antivirus, antioxidant, anti-aging, hypoglycemic effect and improving liver and kidney function. In recent year, a number of investigators reported medicinal fungal polysaccharides showed good anti-diabetes and hypoglycemic activity, and their acting mechanisms involved in glycometabolism and β cell function, e. g. promoting glycogen synthesis, promoting glycolysis, inhibiting the activity of α-glucosidase, promoting insulin secretion, increasing insulin sensitivity, enhancing antioxidation. Therefore, the hypoglycemic activity and its mechanisms of action of medicinal fungal polysaccharides showed characteristics of multiple effects, multi-target, and multi-pathway regulation. These finding suggest that medicinal fungal polysaccharides are a promising source for the development of discovery of anti-diabetic agent.

OBJECTIVE To analyze the epidemiological characteristics,the efficiency of the surveillance system for nosocomial infections in our hospital,the sensitivity,specificity and timeliness of case reporting and to evaluate the efficiencies of the monitoring and reporting system.METHODS We reviewed the nosocomial infection reporting data in the year of 2005 and identified all the reported cases,confirmed cases and under-reported cases.Sensitivity and specificity of the reporting system were calculated based on these data.RESULTS The incidence of nosocomial infection was 3.04% in 2005.A majority(72.07%) of the cases were reported within 7 days of occurrence.Respiratory tract infection accounted for 57.75% of all nosocomial infections and was by far the most common site of concern.The rates of false positive reporting ranged from 14-37% and were statistically significantly associated with the sites of the infection(P

Objective To explore how the spared muscles in upper limbs and trunk compensated for elbow extension movements in patients with SCI at the level of C_5 and C_6.Methods Fifteen patients with SCI at the level of C_5 and C_6 and fifteen healthy subjects were divided into an SCI group and a control group respectively.The surface EMG recorded from the anterior dehoid,middle deltoid,posterior deltoid,triceps braehii muscle,biceps braehii muscle,upper peetoralis,serratus anterior and latissimus dorsi during four elbow extension activities including grasp- ing cup,reaching for light-switch,wheelchair ambulation and upper limb weight-bearing.The relative EMG intensi- ties of muscles were expressed as a percentage of maximal voluntary contraction.Results Several muscles partici- pated in the activity simultaneously when both groups of subjects performed every motor task.But the primary muscles involved in the movements were different between the two groups.Furthermore,the SCI group tended to employ more muscles than the controls to perform a activity.The compensatory strategies used in various motor tasks by the spared muscles were different.Conclusion The motorueuron recruitment patterns used by the C_(5~6)SCI patients in per- forming elbow extension activities could be different from those by the healthy subjects.The patients accomplished performing different motor tasks by changing their compensatory strategies.

When growing and metabolizing through carbon resources of hydrocarbon, Pseudomonas 23 1 produces acidicacid and gas. The amount of acidic acid is 0.015mol/L The output of gas,which thd main composition is CO 2 and CH 4, is 20ml/L. The organic acid and gas is the important reasons of decreasing the viscosity, enhancing the flow and improving the product of oil.
