Objective To investigate the relationship between BMI and blood lipids, blood glucose and blood uric acid. Methods A total of 3 860 employees from a university who underwent physical examination in 2018 were selected and divided into obesity group, fat group, normal group and lean group according to their body mass index. The levels of blood lipids, fasting blood glucose and blood uric acid among different groups were analyzed and compared. Results There were a total of 1,889 people in the obesity group and fat group, accounting for 48.94% of the total. The weight difference among the different groups was statistically significant (P＜0.05), while there was no statistical significance in age difference among different groups. The height in the obese group and fat group was significantly different compared with the normal group. There were significant differences in the levels of triglyceride (TG), high-density lipoprotein (HDL-C) and blood uric acid (UA) in the different groups (P<0.05). The fasting blood glucose level (GLU) in both the obesity group and fat group was significantly different compared with the normal group (P<0.05). With the increase in body weight index, the proportion of high blood fat, fatty liver, hyperglycemia and high blood uric acid all increased significantly as compared with the normal group or the lean group, and the differences were statistically significant (P<0.05). The proportion of fatty liver and hyperuricemia in the male was higher than that in the female. Conclusion The risk of high blood fat, fatty liver, hyperglycemia and hyperuricemia in college faculty and staff was significantly increased with the increase of BMI. It is suggested that the college employees should have a balanced diet, increase exercise, and control BMI within a reasonable range.

A new class of dendrimer polylysine poly(ethylene glycol)-lipid was designed and synthesized. The cationic polymer liposomes were prepared by the lipid film-extrusion and post-insertion two methods with these dendrimer polylysine poly(ethylene glycol)-lipid and other lipids. The structural properties of obtained cationic polymer liposomes were studied by laser light scattering and fluorescence spectrometer. It was demonstrated that the nano sized liposomes with different density of surface cationic charges can be prepared by either lipid film-extrusion or post-insertion methods, but post-insertion process did not affect drug loading, did not influence drug loading capacity and did not induce liposomal morphology and particle size. The density of positive charge does not affect the size and distribution of different liposomes size and distribution. It was the better choice for manufacture because post-insertion method did not cause early release of drug and size changes. Cell binding experiments show that cationic polymer liposomes, especially dendrimer polymer liposomes had higher local charge density, and therefore have dramatic non specific cell targeting ability.
