ABSTRACT
Objective To study the glycosylated hemoglobin in the level difference between different age,sex and provide a reference for the prevention,early diagnosis and treatment of diabetes.Methods 9 094 cases in clinic of population data were included in this study,according to the different age groups were divided into 30 years old or less group (464 cases),30 ～40 years old group (715 cases),41～50 years old group (1 939 cases),51～60 years old group (1 754 cases),61～ 70 (2 290 cases),71～80 years old group (1 497 cases) and ＞80 years old group (435 cases),7 groups of extraction of venous blood tested glycated hemoglobin and compared,analysis of glycosylated hemoglobin levels between different age groups and different gender differences.Results All subjects crowd glycosylated hemoglobin levels were ≤30 years old group (5.42± 0.841) ％,31 ～40 years old group (5.61 ± + 1.088) ％,41 ～ 50 years old group (5.93 ± 1.264) ％,51 ～ 60 years old group (6.18±1.298) ％,61～ 70 years old group (6.21 ± 1.232) ％,71 ～ 80 years old group (6.29 ± 1.270) ％,＞ 80 years old group (6.35 ± 1.314)％ all were a trend of increase with the increase of age,the difference was statistically significant(F=63.81,P＜0.001).The level of glycosylated hemoglobin was significantly higher in male than in female within 70 years of age,and there was significant difference in HbA1c level between 18～50 years old (P＜0.05).Conclusion There was a correlation between the level of glycosylated hemoglobin with different age,sex and increasing with age.It is suitable for physical examination and screening,and in particular,monitoring of glycosylated hemoglobin levels in middle aged and old age.
ABSTRACT
Clinical data of 23 locally recurrent rectal cancer patients underwent radical anterior resection and 69 controls matched by age and gender was retrospectively analyzed to find out the risk factors related to local recur-rence after radical anterior resection of rectal carcinoma. Univariate analysis showed that tumor size, number of positive lymph nodes, distance between tumor and the anal verge and T stage were risk factors for locally recurrent rectal cancer after radical anterior resection. The results of logistic regression analysis showed that T stage ( T4 stage) was an independent risk factor correlated with the tumor recurrence after radical anterior resection and loca-tion of tumor( distance of tumor from the anal verge being less than 5 cm) seemed to be an independent risk factor correlated with the tumor recurrence.
