Objective To investigate the effects of waist and abdomen liposuction on glucose and lipid me-tabolism in patients.Methods 30 female patients with central obesity who underwent the waist and abdomen lipo-suction in our hospital from April 6, 2013 to October 6, 2013 were selected.For all cases, morning fasting blood within 3 months was collected before and after surgery respectively to examine blood glucose, blood lipids, glycated hemoglobin and other inspections.Results Glycated hemoglobin levels of the 30 cases undergoing liposuction sur-gery after 3 months were significantly lower than those at 3 months before surgery (p<0.05).Meanwhile, levels of glucose, lipids, fasting insulin were lower than those before surgery (p<0.05).Conclusion Liposuction can re-duce glycated hemoglobin levels in cases of central obesity.Meanwhile, it can change levels of blood sugar, blood lipids, fasting insulin, which will help reduce risks of complications of diabetics.

Objective: To study the mechanism of chitosan i n inhibiting the proliferation of rabbit aortic smooth muscle cells(SMCs). Methods: By means of c-myc probe labelled with random primers and Northern blot hybridization, we examined the effect of chitosan on vascu lar SMC c- myc mRNA expression, which was stimulated by newborn bull serum (NB S,20%). Results: The oncogene c-myc mRNA expression incerased in cultured vascular SMC 24 h after NBS exposure. These effects were inhibite d by chitosan (20 μg/ml). Conclusion: Chitosan might inhibit the expression of vascular SMC c-myc mRNA stimulated by NBS, through which the proliferation of vascular SMC are inhibited.

Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.
