The craniospinal radiotherapy method was studied by using the whole body positioning frame and base dose plan compensation (BDPC) technique.11 patients with central nervous system malignancies in our hospital were studied. Use whole body positioning frame with the head - neck shoulder and body membrane to immobilize posture, then use BDPC for the intensity-modulated radiotherapy. Target area conformability index(CI), homogeneity index (HI), dose of endangerment organ (OAR) and beam connecting dose distribution are evaluated. The use of base-dose-compensation intensity-modulated plan combined with whole-body positioning technology improves the target area conformability and target uniformity, simplifies the design of craniospinal radiotherapy, improves the placement accuracy and ensure good placement repeatability. We measure beam connecting dose distribution. Cold and hot spots do not appear, and calculated values are basically identical. The application of whole-body positioning technique combined with BDPC optimization method in the treatment of the craniospinal radiotherapy meets the clinical requirements of dosimetry. Moreover, it is simple and can improve the treatment planning efficiency.

Objective To explore the effect of system details nursing intervention on the precaution of complications of nasal feeding in coma patients with severe brain injury in the department of neurosurgery so as to serve the patients better .Methods Two hundred and twelve coma patients with severe brain injury from March 2010 to February 2013 were chosen as the observation group , and the 175 patients from May 2008 to January 2010 were retrospectively analyzed as the control group .The control group received the routine nursing , and the observation group received the system details nursing intervention on the basis of the routine nursing .The nutritional status and the incidence rate of complications were compared between the two groups .Results The cases of malnutrition in the control group were 9 cases (5.14%), and were 0 case in the observation group , and the nutritional status in the observation group was better than that in the control group , and the difference was statistically significant (χ2 =5.127, P<0.05).The cases of nasal feeding complications in the control group were 41 cases (23.43%), and were significantly higher than 22 cases (10.38%) in the observation group, and the difference was statistically significant (χ2 =4.907, P <0.05).Conclusions The system details nursing intervention can effectively reduce the incidence of nasal feeding complications , and improve the quality of nursing and ensure the supply of nutrients , and helps the patients to recover as soon as possible .

Objective: To evaluate the utility of the Werry-Weiss-Peters Activity Rating Scale (WWPARS) for children with a Chinese background. Methods:In the city of Changsha, 465 normal children aged 8～12 in two primary schools and 27 ADHD children in an outpatient department were tested with WWPARS. Psychometric properties of the scale were analyzed for reliability and validity. Results: While levels of activity increased with age for all children, there was no significant difference between the two groups assessed. The scale attained good reliability and validity. Conclusion: This scale can be applied for evaluation of activity levels for Chinese children.
