Exendin-4,a peptide analogue of glucagon-like peptide-1(GLP-1),is presently in clinical trials as a therapy for type 2 diabetes mellitus.Exendin-4 selectively acts on GLP-1 receptors,which are coupled to the cAMP nucleotide second messenger pathway to enhance the survival and plasticity of neurons in the brain.Exendin-4 has potent effects on homeostasis of Ca2+,on multiple targets to block apoptotic signaling pathways,and on neuronal proliferation and differentiation.It has also been demonstrated to possess properties against oxidative stress and excitotoxicity.In this review the functions of exendin-4 on central nerve system and the potentia therapeutic effects on neurodegenerative diseases will be involved.

BACKGROUND: Polyvinyl alcohol hydrogel (PVA) has been generally considered as a good substitute material of articular cartilage. Polyamide 66 (PA66) polymer has achieved an extensive application in the fields of engineering and medicine owing to its high intensity, strong tenacity and good stability. Polyurethanes exhibit good histocompatibility and blood compatibility and show distinct advantages in repairing cartilage.OBJECTIVE: To compare the outcomes of repairing articular cartilage defects in rabbit knee joints with three materials and to find the best material.METHODS: Thirty-six healthy adult New Zealand rabbits were prepared for the models of articular cartilage defects by perforating on the patellofemoral joint and randomly divided into 4 groups, with 9 animals in each group. PVA, polyurethane, and PA66 were implanted into the into articular cartilage defects in rabbits of corresponding groups. There was no treatment in the control group.The macroscopic and histological evaluations of rabbit knee joints were performed at 4, 8 and 12 weeks postoperatively. The score of histology was used to evaluate the repairs of articular cartilage defects at 12 weeks postoperatively.RESULTS AND CONCLUSION: No infection was observed in all animals with good motion of joints. At 12 weeks postoperatively, the materials got well with surrounding cartilage, which did not degenerate obviously. The defects in the control group were filled with fibrous scar-like tissues that arranged in disorder. The histological score of the in the group implanted by PVA, as well as polyurethane, was higher than that in PA66 and the control groups (P < 0.05), but the difference between the two groups had no significance (P>0.05).The porous materials PVA and polyurathane have good function for replacing articular cartilage, with good biocompatibility.

Objective To study the therapeutical effect of glutathione(GL),a powerful antioxidant on the symptoms and ECG in patients with coronary heart disease and its mechanisms.Methods Eighty-five subjects with coronary heart disease were recruited(45 male and 40 female).The patients were randomized to receive GL (240 mg,ivgtt,qd,for 14 days,n=44)on the top of conventional treatment(aspirin+?-blocks+ACEI)or conven- tional treatement alone(control,n=41).The serum MDA,SOD,NO levels were determined.Electrocardio- graphy(ST stage,T wave)was examined.Results GL significantly improved clinical symptoms scores(2.0+0.5 vs control:1.5+0.5,P

Objective To establish a method to isolate and cultivate rat bone marrow mesenchymal stem cells (BMSCs),and explore the feasibility of labeling in vitro,and tracing in vivo,BMSCs with chloromethyl-benzamidodialkylcarbocyanine (CM-Dil). Methods BMSCs were obtained and subsequently cultured with whole bone marrow cell culture system,and the third generation of BMSCs was harvested. The positive rates of CD34,CD44 and CD29 were detected by flow cytometry. CM-Dil was used to label BMSCs in vitro and the efficiency of labeling after 24 hours and at day 21 and 30 were examined under fluorescent microscope. Moreover,the growth curves were sketched to determine the negative effects of CM-Dil on the vitality and proliferation of BMSCs cultured in vitro. Rat model of focal cerebral ischemia was reproduced,CM-Dil labeled BMSCs were implanted into corpus striatum of rats' brain with computer-guided stereotaxis thereafter. Brain tissues were obtained to prepare frozen sections at 7th,14th and 21st day post-implantation,and the survival and distribution of labeled cells were observed with fluorescent microscopy. Results The third generation passage of cultured BMSCs grew orderly,with shape of desmocytes,and homogeneous in morphology. The positive rates of CD34,CD44 and CD29 expressions in BMSCs were 1.71%,80.32% and 84.89%,respectively. Red fluorescence was observed in CM-Dil labeled BMSCs in vivo 24 hours after labeling,with a positive rate of 100%. The fluorescence intensity of passage cultured BMSCs observed on day 21 was similar to that observed at 24 hours after labeling,but diminished on day 30. The growth,proliferation and morphology of BMSCs,were not influenced by CM-Dil labeling. On day 7,14 and 21 post-implantation,BMSCs decreased in quantity,appearing in oval or irregular shapes,and most of the cells were found around the needle tract,with a tendency of diffusion to peripheral area. Conclusion High purity of BMSCs may be obtained with whole bone marrow cell culture system from bone marrow of rats. CM-Dil labeling is easy to handle and effective,with no cytotoxicity to cells. The latest labeling period of CM-Dil is 21 days in vitro,therefore it seems to be an effective method for in vivo tracing of BMSCs in brain after implantation.

Translational medicine appears as a new branch of medicine, aiming at quickly transforming the basic research products into clinical application. Nowadays there is a trend that laboratory researches do not have a close relationship with clinical reality, which is facing the present medical research and education field. Herein translational medicine appeared to solve this fundamental conflict.In this paper, we will analyze the essence and status quo of translational medicine, and provide suggestion on the development of translational medicine from the perspective of medical research management.

BACKGROUND:The assessment for long-term efficacy of chronic ischemic disease is more important than the short-term efficacy assessment, which associates with patient’s long-term quality of life and long-term survival rate. OBJECTIVE:To observe the 5-year folow-up outcomes of autologous bone marrow stem cel transplantation for the treatment of thromboangitis obliterans. METHODS:This study enroled 43 patients of thromboangitis obliterans who underwent autologous bone marrow stem cel transplantation from August 2007 to January 2010 in the Department of Thyroid Vascular Surgery, the First Affiliated Hospital of Xinjiang Medical University. At 1, 2, 3, 4 and 5 years after transplantation, pain, cold sensation, and intermittent claudication distance were folowed up by telephone; changes in limb ulcers were observed. At 1 year after transplantation, venous oxygen partial pressure and oxygen saturation of limbs were reviewed. RESULTS AND CONCLUSION:A total of 38 thromboangitis obliterans patients with complete folow-up data were included in the final analysis. Compared to the preoperation, pain, cold sensation, and intermittent claudication significantly improved. The difference was statisticaly significant (Z values:-4.277,-5.086,-3.574, P < 0.001). Compared with 1-5 years after operation, pain and cold sensation had no statisticaly difference (P >0.05). Intermittent claudication distance had increased. Differences in terms of intermittent claudication distance was statisticaly significant (Z=43.898,P < 0.001). Significant differences in venous oxygen partial pressure and oxygen saturation were detected between preoperation and 1-year posttransplantation (tvalues: 36.790, 43.964,P values: 0.040, 0.037). Above results suggest that autologous bone marrow stem cel transplantation for thromboangitis obliterans obtained stable long-term outcomes.
