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.

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.

BACKGROUND:Healthy human umbilical cord jel y is a mucous connective tissue without vessels and has been used in eye plastic operation because of its elasticity and toughness. It contains lysozyme, placental globulin, hyaluronic acid enzyme, AMP antibody and complement, and also contains a lot of mesenchymal stem cells, so it is not prone to infection and rejection. OBJECTIVE:To observe the histocompatibility and histopathological changes of human umbilical cord jel y as a tarsal substitute transplanted for eyelid reconstruction in guinea pigs. METHODS:The mucous connective tissue of healthy neonate umbilical cord jel y was made into tissue blocks at even thickness. Models of tarsal defects were established in guinea pigs, and then the mucous connective tissue of healthy neonate umbilical cord jel y was implanted. Samples of implanted materials were col ected for histological examination at 1, 2, 3 weeks postoperation under light microscope. RESULTS AND CONCLUSION:There were no obvious rejection, infection and eyelid deformation observed, the corneas of al the animals were clear, corneal epithelial shedding did not occur, and the eyelid could move normal y. One week after implantation, there was no infection and rejection on the conjunctiva and the incision of the eyelid, the eyelid could move normal y, and partial inflammatory cells were observed between the human umbilical cord jel y and the muscle of the eyelid with microscopy. Two weeks after implantation, there was no infection and rejection on the conjunctiva and the incision of the eyelid, the cornea was clear, the eyelid and eye could move normal y, and no symblepharon occurred;umbilical cord jel y showed the tendency of absorption, and the inflammatory cells were reduced at 2 weeks after implantation. Three weeks after implantation, the incision of the conjunctiva healed wel , the cornea was clear;there was no difference in the eyelid form and movement between the two eyes;the umbilical cord jel y was absorbed partial y, normal fibrous tissues formed and there were no inflammatory cells. With low immunogenicity, human umbilical cord jel y can guide the growth of new col agen and serve as an ideal tarsal substitute.

Objective To investigate the localization and surgical outcome of epileptogenic nidus of post-traumatic epilepsy. Methods A retrospective analysis was performed on clinical data of 62 patients with post-traumatic epilepsy treated microsurgicallly from November 2005 to May 2009. There were 48 males and 14 females, at age range from 11 to 48 years old (average 28.8 years old). The epileptogenic nidus in 59 patients was localized based on clinical manifestations, visual electroencephalography (V-EEC) imaging and electrophysiological findings and that in three patients localized by implanted intracranial electrodes. Under electrocorticogram (ECoG) monitoring, we resected cerebral malacia in 36 patients, removed both malacia and epileptogenic nidus in 15, and partially resected cerebral malacia combined with cortex thermocoagulation in 11. Results The follow-up for 6-33 months showed that there were 32 patients at grade Ⅰ , 17 at grade Ⅱ , nine at grade Ⅲ and four at grade Ⅳ according to Engel classification system. Conclusion V-EEG is an important method for pre-operative localization of epileptogenic nidus of post-traumatic epilepsy. Microsurgical management can attain favorable outcome under ECoG monitoring.

AIM: Recent studies showed that stem cells could replace injured cardiomyocyte and increase the number of functional cardiomyocytes. Researching the pertinent literature in China Journal Full-text Database (CJFD) published between 2005 and 2008 indicated that the researches on stem cell transplantation in the treatment of primary dilated cardiomyopathy were few. This study investigated the therapeutic efficacy and security of peripheral blood stem cell transplantation in coronary artery in treatment of dilated cardiomyopathy and its effects on left ventricular function. METHODS: Forty-two patients with dilated cardiomyopathy between December 2006 and September 2007 were enrolled at the Department of Cardiology of First People's Hospital of Yunnan, including twenty-eight males and fourteen females, averagely aged (56?3) years. Inclusive criteria: patients with less than 65 years, left ventricular enlargement, and left ventricular ejection fraction (LVEF) ≤ 45%, and without coronary artery disease after coronary arteriongraphy. Informed consents were obtained from patients. Patients were divided into stem cell transplantation group (n=15) and control group (n=27) on the basis of whether being treated by stem cell transplantation. Patients in the stem cell transplantation group were consecutively administered granulocyte colony-stimulating factor (G-CSF) by hypodermic injection to stimulate bone marrow stem cells themselves based on conventional treatment for five days. Peripheral blood stem cell suspension was disassociated on the 6th day, and the collected suspension was injected into left anterior descending branch over the wire saccule tube for autologous peripheral blood stem cell transplantation. Patients in the control group were administered by conventional treatment of dilated cardiomyopathy. Security and adverse reaction were observed during the mobilization, collection and returning injection of peripheral blood stem cell by coronary artery. Morphous, cardiac function and motion index of left ventricle wall were evaluated using ultrasoundcardiogram before and 3 months after transplantation. Survival rate and incidence rate of heart incidents were compared. RESULTS: Three months after stem cell transplantation in coronary artery, there were a significant decrease in cardiac end-systolic volume (ESV), cardiac end-diastolic volume (EDV) and motion index of left ventricle wall, but a significant increase in LVEF(P

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.

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.
