OBJECTIVE: To investigate the effects of deproteinised calf blood injection(DCBI) on blood glucose and lipid metabolism and its ameliorating effect on insulin resistance(IR) in model rats with type 2 diabetes mellitus(T2DM) complicating cerebral infarction.METHODS: Rats were fed with high fat and high glucose diet and injected with streptozotocin(STZ) vial caudal vein to duplicate T2DM model,followed by duplication of middle cerebral artery occlusion(MCAO) rat model.Then the rats were assigned to model group,sham-operated group,DCBI low and high dosage group(30,60 mg? kg-1?d-1 intraperitoneally),and rosiglitazone control group;meanwhile,another normal group was established.After receiving the corresponding drugs for 5 weeks for each group,fasting blood glucose(FBG),serum insulin(FINS) and sugar tolerance(OGTT) were determined,and levels of insulin resistance index(IRI),insulin sensitivity index(ISI),total cholesterol(TC),triglyeride(TG),high-density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),and free fatty acid(NEFA) levels were computed.RESULTS: As compared with model group,in DCBI-treated model rats with T2DM complicating cerebral infarction,FBG were significantly decreased,sugar tolerance increased significantly(P0.05);IR was ameliorated(P

Objective To evaluate the clinical application of helical CT 3D reconstruction technique in the dental orthopaedics. Methods The helical CT was performed with 3.0 mm slice thickness and 1.0 pitch in 41 patients with dental orthopaedics. The 3D reconstructions, including maximum intensity projection (MIP), surface shaded display (SSD), and multiplanar reconstructions (MPR), were made for all the cases. Results Thirty-seven of the 41 patients showed malalignment, tilt, rotation, overlap of the teeth and the different space between the longitudinal axes of the teeth. Twenty-five cases of them have shown 36 buried teeth in all. The axial images covered all the information. SSD demonstrated the external contours and entire morphologies of the teeth and the mandible with the relationship of the teeth alignment and the mandible. MIP clearly manifested the full view and the longitudinal alignment of the teeth. Among the 36 buried teeth, there were 29 palatally and 7 labially presented teeth, and they were morphologically delineated on MIP through various angles. Conclusion The helical CT 3D reconstruction is a new technique to display the stereoscopic configuration of teeth. The combination of axial images and MIP, SSD, and MPR provides valuable anatomic and diagnostic information helpful for the surgeons to structure and determine the treatment protocol for the dental orthopaedics.

Objective To screen the anti-tumor prescription (Shengzao Fang) of Shengma (Rhizoma Cimicifugae) combined with Zao Jiao-ci (Spina Gleditsiae), and evaluate its anti-tumor effects. Methods The lung metastatic model of 4T1 breast cancer and the 4T1 subcutaneous transplanted model were established, both models of mice were randomly divided into model group, Shengma group, Zao Jiao-ci group, Shengzao Fang first group, Shengzao Fang second group and Shengzao Fang third group, 10 mice for each group. The proportion of Shengzao Fang was ascertained by their anti-tumor effects. MTT assay was used to investigate the effects of Shengzao Fang on 4T1 breast cancer. The concentration of type 1 collagen (Col-Ⅰ), platelet-activating factor (PAF), tissue inhibitor of metalloproteinase 1 (TIMP-1), tyrosine kinase receptor A (TrkA) and tyrosine kinase receptor B (TrkB) in serum from tumor-bearing mice was tested by enzyme-linked immunosorbent assay (ELISA). The effects of Shengzao Fang on matrix metalloproteinase (MMPs) was examined by Gelatin matrix method. Results Compared with the model group, the prescription of Shengma∶Zao Jiao-Ci=2∶1 significantly suppressed lung metastasis of 4T1 breast cancer, showing fewer lung nodes, lower lung metastasis rate and highest tumor inhibitory rate to 4T1 subcutaneous transplanted model. Although the concentration of serum Col-Ⅰ, PAF, TIMP-1, TrkA and TrkB was decreased in all treated group, the prescription of Shengma∶Zao Jiao-ci=2∶1 had the strongest activity, and its inhibitory effect on the expression of MMP-2 and MMP-9 was strongest, too. Conclusion The prescriptions of Shengma combined with Zao Jiao-ci had different antitumor activity, the strongest activity was exhibited when shengma∶Zao Jiao-ci was 2∶1, suggesting that 2∶1 was optimization for Shengma combined with Zao Jiao-ci.
