Objective: To analyze the clinical effect of modified standard traumatic craniectomy and standard large trauma craniectomy in the treatment of severe craniocerebral trauma.And to evaluate the clinical value of modified standard traumatic craniectomy in the treatment of severe craniocerebral trauma. Methods: Ninety-two patients with severe craniocerebral trauma treated in Rugao Bo′ai Hospital (GCS3-8, acute subdural hematoma) from January 2015 to January 2017 were divided into two groups using random envelope drawing method, with 46 cases in each group.The control group was treated by standard large trauma craniectomy, and the observation group was treated by modified standard traumatic craniectomy.The intracranial pressure levels and activity of daily living scale (ADL) were compared between the two groups. Results: At 1 d, 5 d, 10 d after operation, the intracranial pressure levels of the observation group were (23.19±2.82)mmHg, (15.26±2.77)mmHg and (11.22±2.75)mmHg, respectively, which were lower than those of the control group[(28.12±2.32)mmHg, (19.14±2.17)mmHg and (14.23±2.17)mmHg](t=47.544, 37.922, 29.504, all P<0.05). At 6 months after operation, according to ADL, the good rate of postoperative recovery in the observation group (67.39%, 31/46) was significantly higher than the control group (45.65%, 21/46), the difference was statistically significant(χ²=4.423, P<0.05). Conclusion The modified standard traumatic craniectomy has a certain value in the treatment of patients with severe craniocerebral trauma.

Objective To understand the current situation of breastfeeding duration in children aged 0-5 years in Yunnan Province,and to explore the influencing factors of breastfeeding duration.Methods Using the data of the 6th National Health Service Survey in Yunnan Province,1582 children aged 0～5 years in Yunnan Province were selected as the research subjects,and the Kaplan-Meier method and Cox regression were used to analyze the influencing factors of breastfeeding duration.Results The mean duration of breastfeeding for children aged 0～5 years in Yunnan Province was 9.29 months,and region,time of complementary food addition,time of suckling and family income were the main factors influencing the duration of breastfeeding.Conclusion The duration of breastfeeding for children aged 0～5 years in Yunnan Province deviates significantly from the recommendations provided by both the World Health Organization(WHO)and China's child breastfeeding guidelines.Given the current situation,the relevant departments must enhance their focus on this issue.
