The fistulas of 9 cases were occluded with patency of internal carotid artery(ICA),and ICA were occluded in 19cases.Conclusions Endovascular embolization of carotid cavernous fistula was safe and effective.This methed should be the first choice for the treatment.Different techniques of endovascular embolization should be undertaken for different CCF.

Metformin is the most commonly prescibed drug for type 2 diabetes mellitus as it is inexpensive, safe, and efficient in ameliorating hyperglycemia and hyperinsulinemia. Numerous epidemiological studies indicate that diabetic population is not only at increased risk of cardiovascular complications, but also at substantially higher risk of many forms of malignancies. Meanwhile, epidemiological and clinical observation studies have shown that metformin use reduces risk of cancer in patients with type 2 diabetes mellitus and improves prognosis and survival rate of the cancer patients. Furthermore, metformin has been used for cancer therapy in clinical trials. Thus, metformin is emerging as a new cancer therapy or adjuvant anticancer drugs. This review summarizes recent progress in studies of metformin use and its molecular mechanism.

AlM: To explore the clinical therapeutic effect of the integrated traditional Chinese and Western medicine treatment of idiopathic panuveitis.
METHODS: Totally 47 patients ( 69 eyes ) with the idiopathic panuveitis were included in this study, which were randomly divided into control group and treatment group. Twenty-four cases (33 eyes) with the method of Western medicine-glucocorticoid and mydriatic were in control group, while 23 cases (36 eyes) with integrated traditional Chinese and Western medicine were in treatment group. Those patients were followed up 12-36mo, the vision before and after treatment, the therapeutic effects, the complications and the side effects of glucocorticoid were recorded.
RESULTS: Both of two groups' vision after treatment were improved, but the vision of treatment group was better than the control group. The effective rate and the cure rate of the treatment group were increased significantly. Of all of the complications, the incidence rate of complicated cataract and secondary glaucoma of the treatment group were reduced significantly. Of all of the side effects of glucocorticoid, the central excitation, hypertension and central obesity of the treatment group were reduced significantly (P<0. 05).
CONCLUSlON: Dialectical therapy of integrated traditional Chinese and Western medicine has better therapeutic effect than simple Western medicine treatment of idiopathic panuveitis, and could better reduce the side effect of glucocorticoid long-term use. lt is worthy applying in clinical practice.

AIM To investigate protective effects and mechanism of tanshinones on ischemia-like injury models. METHODS Six ischemia models including hypoxia, hypoglucose, oxidant injury, caffeine injury, nitric oxide neurotoxicity and excitatory amino acid injury were used to assay the anti-ischemic roles of tanshinones in cultured primary cortex neurons. The changes of injuried cortex neurons were observed by the way of morphological examination, and live neurons of crystal violet staining were measured according to absorbent index. RESULTS it was found that tanshinones possessed obvious protective effects on primary neurons in injury models by the way of morphological e~nation. Crystal violet staining also indicated that tanshinones increased number of live neurons in injury models significantly. The protective effects of tanshinones on models of oxidant injury, caffeine injury and NMDA injury were superior to other injury models. CONCLUSIONS 83.0 ?mol? L- 1 tanshinones protected rat cortex cells fm all injury models effectively in vitro.

Objective: To research endogenous metabolites changes of model group on human umbilical vein endothelial cells (HUVECs) injury induced by advanced glycation end products (AGEs) and the accommodation mechanism of morroniside (active components in Cornus officinalis) on the abnormal metabolism. To find potential biomarkers which morroniside protected the injured HUVECs, and to explore mechanisms of morroniside in treatment of HUVECs injury induced by AGEs. Methods: HUVECs were cultivated in vitro, HUVECs injury model was established by the induction of AGEs. Cells were divided into three groups, control group, model group, and treatment group. Cell samples of three groups were determined with UPLC-Q-TOF/MS. Pattern recognition methods including PCA, PLS-DA, and OPLS-DA were applied to analyze multivariate data, and t-test was used in significant statistical analysis. It was used to find out potential biomarkers. Metabolomic feature network graphs were constructed ingenuity pathway analysis (IPA). Results: In pattern recognition, control group, model group, and treatment group could be distinguished better from each other. According to VIP values, 30 ions which had a significant contribution to the classification were screened further, 10 potential metabolic biomarkers were identified qualitatively. These endogenous substances of the cells in treatment group in vivo had varying degrees of recovery. Five metabolic pathways were identified, and a metabolomic feature network of morroniside to protect against HUVECs injury induced by AGEs was constructed. Conclusion: Changed metabolities on HUVECs injury induced by AGEs can be certainly recovered by morroniside, and the treatment effect of morroniside can be connected with the regulation of five related metabolic pathways.

Aim To investigate whether rosuvastatin induced reduction of atherosclerotic plaque was related to the expression of Sialyltransferase ( ST6 Gal-Ⅰ) in ApoE-/ - mice. Methods Six-weeks old ApoE-/ -mice fed with high fat were divided randomly into three groups: baseline group ( n=12 ) , control group ( n=12 ) and rosuvastatin group ( n =12 ) . Sixteen weeks later, control group was sacrificed. Serum and aortic intima were saved. Control group and rosuvastatin group were fed for seven weeks continually. Concentra-tions of serum lipids(TC, TG, LDL and HDL) were analyzed. Sections from the aortic root were examined by Hematoxylin-Eosin( HE) staining. The size of ath-erosclerotic lesion in each section was evaluated. Ex-pression of ST6 Gal-Ⅰ in aortic intima was detected by immunohistochemistry. Results Plasma TG and LDL-C, plaque areas and intimal thickness of control group were significant higher than those of baseline group ( P<0. 05 ) . Those results indicated that the AS model was successfully constructed. After seven weeks, the plaque areas and concentrations of serum lipids of rosu-vastatin group were obviously smaller than those of con-trol group(P<0. 05). The expression of ST6Gal-Ⅰin aortic root was decreased in control group compared to the baseline, and which was increased in control group compared to the rosuvastatin group. Conclusion Ro-suvastatin could inhibit the progression of atherosclero-sis, which might be related to the expression of ST6Gal-Ⅰ in aortic root.
