Spatial distribution pattern of larvae of Aleurocanthus spiniferus in citus garden was studied by means of some distribution parameters such as mean crowding, David and Moor's clustering index, index of patchiness, proliferation index, the distribution of negative binomial, Iwao's patchiness, the and Taylor's law. The results showed that the spatial distribution pattern of larvae under all densities appeared to be aggregation distribution, which is characterized by individual attraction and predominant individual group such as cored distribution pattern.

Result The medullary index interval of hairs from the back, abdomen, neck and hip of large indian civet was between 68.8% and 87.5%, the same index in small indian civet was between 62.5% and 87.5% and in masked palm civet was between 42.9% and 61.6%. There were differences on the scale pattern between genera and species and the differences were also found in different parts of the same animal and in different parts of the same hair.

The statistical difference of proinsulin rather than HOMA index was found among the patients of various Gensini's score group (Gensini's score was examined as a categorical variable classified by tertile values) and significantly stenosed vessels group by means of the results of analysis of covariate variance after adjusting for age, sex and body mass index (p<0.05), and the partial correlation coefficient between proinsulin level and Gensini's score, the number of significantly stenosed vessels after adjusting for age, sex and body mass index was 0.3156 (P<0.01) and 0.2752 (P<0.05) respectively. Multivariate linear regression analysis indicated that the level of proinsulin was positively correlated with the Gensini's score (P<0.01). The results of multivariate stepwise Logistic indicated that the proinsulin was the independent risk factor for the coronary heart disease, and the odds ratio (95% confidence interval) was 2.268 (1.253~4.105)(P=0.007), however, the HOMA was refused by the final model.
