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.

Objective To explore the influence of feeding styles in early stage on children′s weight in different stages.Methods A complete record of 918 healthy infants was selected and then divided into 3 feeding groups:breast feeding, mixed feeding and artificial fee-ding, according to the way of feeding in the first 6 months after birth. Their weights and heights were measured in the 3rd,5th,8th,12th,18th,24th,60th month to conduct the Z score of weight for age (WAZ), weight for height (WHZ) and the body mass index (BMI) of 60-month-old infants.An investigation on the time of adding auxiliary food was conducted.Results The heavier,WAZ and WHZ of breast feeding group in the 3rd month were higher than the other groups,and the differences were statistially significant(F=4.12, 5.66, 5.79 Pa

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
