The signs and results of 14 patients with small hepatocelular carcinoma HCC of a diameter less than 3 cm (in 10 of them the daignosis was proven by pathology after surgery) obtained by CT,angiography and CT angiography were described in this article. The value of the above imaging modalities in the detection and diagnosis of small HCC was discussed with emphasis on the significance of the sequential staining sign from interior to exterior in CT and angiography.

Objective To investigate the effect of urinary training on urination control in infants using nappies after birth.Methods Stratified sampling method was used to investigate the daytime urination control and the using of diapers by children in kindergartens of 6 prefecture-level cities in Henan Province,China.The survey was conducted among parents of healthy children.Results In a total of 12 250 questionnaires,11 697 had response,and 10 562 valid questionnaires were collected,and the effective recovery rate was 86.22%.After the birth of infants,the age of toilet training was divided into 6 groups (0-< 3 months old group,3-< 6 months old group,6-< 12 months old group,12-< 18 months old group,18-< 24 months old group and no toilet training group).Results showed that toilet training within 12 months leads to higher urinary control rate compared with toilet training after 12 months and no toilet training till the age of 2 years old,70.56% (4 831/6 847 cases) in contrast with 59.02% (1 545/2 618 cases) and 42.48% (466/1 097 cases),and the differences were statistically significant (x2 =114.76,335.48,all P < 0.000 1).Within 12 months,there was no statistical difference in the urinary control rate between subgroups at 2 years of age(all P >0.05).After 12 months,the urination control rate decreased with the start time delayed till 2 years of age,and the urinary control rate at the age of 2 years old n different groups was 59.97% (1 314/2 191 cases) and 54.10% (231/427 cases) respectively.The results of other ages(0.5,1.0,1.5 years old) were similar to those of 2 years old.There was no difference between the groups of different genders (all P > 0.05).Conclusions The use of diapers in infants before the age of 1 year to start urinary training is conducive to the development of urinary control in infants.
