ABSTRACT
Objective@#To investigate the nutritional status and its relationship with the indexes of physical function and physical capacity among primary and middle school students in Xiamen, so as to provide statistical support for improving their nutritional status and physical health.@*Methods@#A total of 2 752 primary and middle school students aged between 6 and 18 years old were selected in Xiamen. They were divided into malnutrition group, normal group and overweight and obesity group according to the national standards. Statistical analysis was carried out by chi square test, Kruskal wallis test and partial correlation analysis.@*Results@#The prevalence of malnutrition among primary and secondary school students in Xiamen was 8.4%(231), the prevalence of overweight and obesity was 24.2%(667), and the prevalence of overweight and obesity among boys(31.4%) was higher than girls( 17.0 %).The distribution of nutritional status between different ages was statistically significant ( χ 2=40.43, P <0.05). On the lung activity index, both boys and girls were shown to be overweight and obesity<normal weight group<malnutrition group( χ 2=14.2,5.6; 17.2, 11.6, P <0.01)；Both girl and boy students in grip body mass index, 50 meter running and PFI were shown to be better than overweight obesity ( χ 2=99.5, 6.6, 10.4; 8.18, 5.16 , 7.13, P <0.05).@*Conclusion@#The prevention and control situation of overweight between primary and secondary school students in Xiamen city, is more serious. Overweight and obesity are related to decline in physical function and physical fitness. Nutritional status should be paid more attention for physical fitness improvement among students.
ABSTRACT
The abdominoperineal excision (APE) is still one of the standard operations for low rectal cancer. The exralevator APE can reduce the positive rate of circumferential margin and perforation rate of rectal cancer, but the incidence of postoperative complications is relatively high. With the continuous development of minimally invasive surgery, the transperineal minimally invasive Abdominoperineal excision (Tpm-APE) is proposed. Compared with traditional APE, the Tpm-APE has potential technical advantages, but there is a lack of large sample and multicenter clinical research evidence. The authors share the design and results of an international multicenter clinical study to investigate the clinical practice of Tpm-APE in the treatment of low rectal cancer.
