Objective To investigate the epidemiologic features of injuries in children aged 0-14 years in Suzhou, so as to provide targeted education and prevention guidance for parents and schools. Methods Complex sampling was used to choose 4 989 children aged 0-14 years in Gusu and Wujiang districts in Suzhou. The primary caregivers filled out an injury occurrence questionnaire to analyze the distributions of injury numbers, occurrence time and locations. Results In the past 12 months, the overall incidence of children injuries was 7.7%, with 95% confidence interval (CI) was 6.9%-8.4%. The incidence tended to decrease with age ( 2=5.06, P=0.025), however, increase with monthly increase ( 2=28.51, P<0.001).Of all types of children injuries, the incidence of fall was highest (65.5%). Head and face injuries were the most common (45.3%). Most of injuries occurred at home (59.5%) and during leisure play (32.2%). 81.3% of the injuries were slight, and 45.4% of the injuries were dealt with infirmaries. 9.7% of the injured children recovered with aesthetics impact. Young children were more likely to experience head fall or burn injuries during leisure play. Young girls were more likely to experience injuries at home. However, older children were more likely to have lower limb injuries during sports and housework. Older boys were more likely to be harmed at school. Conclusions Different age and gender children had different injury epidemiological characteristics. Specific preventive measures should be taken according to their characteristics.

[Objective] To compare the influence of first-degree relatives' cancer history on the genetic tendency of gastric and colorectal cancer. [Methods] Patients with gastric and colorectal cancer from six towns of Suzhou City were investigated by means of face-to-face survey based on the "Family History and History of Population Diseases Questionnaire"which included general conditions, family composition and cancer occurrence of all their three degree relatives. [Results] If there were first-degree relatives with history of cancer, individual risk of gastric cancer would be higher than that of colorectal cancer by 55％, with the adjusted OR (95％ CI) being 1.551 (1.021, 2.356). If there were first-degree relatives with history of digestive tract cancer, the risk of the subject would increase to 104％, with the adjusted OR (95％CI) being 2.037 (1.279, 3.246). Men with first-degree relatives who had cancer history was at91％ higher risk of developing gastric cancer than colorectal cancer, with the adjusted OR (95％CI) being1.911 (1.080, 3.381). And for history of digestive tract cancer, the risk would reach 156％, with the adjusted OR (95％ CI) being 2.559 (1.337, 4.897). The number of cancers suffered by first-degree relatives of those patients with gastric cancer was higher than that of patients with colorectal cancer, with Z =-6.873, P<0.001, while the number of digestive tract cancer was also higher, with Z =-6.137, P<0.001. [Conclusion] The history of cancer and digestive tract cancer with first-degree relatives, is more common in patients with gastric cancer than with colorectal cancer. It is necessary to focus health education on men with first-degree relatives suffering from cancer or digestive tract cancer and suggest some changes in their living habits and regular medical examinations to reduce the occurrence of gastric cancer.
