Objective:To explore therapeutic effect of repaglinide on patients with type 2 diabetes mellitus (T2DM) complicated atherosclerosis (AS).Methods:A total of 120 T2DM + AS patients treated in our hospital from Mar 2012 to May 2014 were selected.They were randomly and equally divided into repaglinide group (received repaglin- ide treatment)and glipizide group (received glipizide treatment).Fasting blood glucose (FBG)and 2h postprandial blood glucose (2hPG)levels before and after treatment,serum levels of high sensitive C reactive protein (hsCRP) and oxidized low density lipoprotein (oxLDL)after treatment,and patients'satisfaction on treatment were com- pared and analyzed between two groups.Results:Compared with before treatment,there were significant reductions in levels of FBG and 2hPG in both groups after treatment (P<0.01 all);compared with glipizide group,there were significant reductions in levels of FBG [(6.94±0.41)mmol/L vs.(6.05±0.54)mmol/L],2hPG [(8.03±0.74) mmol/L vs.(7.66±0.78)mmol/L],serum hsCRP [(5.75±0.26)mg/L vs.(4.71±0.32)mg/L]and serum ox- LDL [(98.30±25.05)μg/dl vs.(52.21±17.50)μg/dl]after treatment in repaglinide group,P<0.01 all.Satis- faction rate in repaglinide group was significantly higher than that of glipizide group (93.33% vs.60.00%),P<0.01. Conclusion:Repaglinide possesses significant therapeutic effect on patients with type 2 diabetes mellitus com- plicated atherosclerosis.It can significantly reduce blood glucose,blood lipid and serum hsCRP levels.

Allergic rhinitis is a common disease, which was released by the IgE-mediated atopic individuals exposed to allergens in the earlier researches. However, there are variety of immunocompetent cells and cytokines involved in the nasal mucosa immunologic mechanism in nowadays researches. The mechanism of AR is caused by the imbalance of the Th1/Th2, a kind of allergic inflammation who is characterized by the nasal Th2 immune response dominant. Th1 cells mainly produce of IFN-gamma (does not include IL-4 and IL-5), Th2 cells produce IL-4, IL-5, IL-9 and IL-13 (not including IFN-gamma). Recently it was found that regulatory T cells (T regulatory cells, Treg) and Th17 cell research played a crucial role in the occurrence of allergic inflammation.

Objective To evaluate the impact of influenza virus hemagglutitin (HA) 306-318 peptide on T cell activation and to investigate the inhibitory effect of the altered HA306-318 peptide on T cell proliferation. Methods HA306-318 peptide and its mutant containing amino acid substitutions were synthesized. They were used in T cell activation assay using HLA-DR1 transfected cells. Responses were determined by MTT proliferation assays. The HA mutant without stimulating effect on T cells was then examined by inhibiting HLA-DR1-restricted T cell activation. Results It was demonstrated in this study that the altered HA306-318 peptide bound to HLA-DR1 molecule on L57.23 cells transfected with HLA-DR1 cDNA, but not on the control cells. The altered HA306-318 peptide had no stimulating effect on T cells compared with the wild type HA306-318 which induced T cell proliferation. It was shown that the altered HA peptide inhibited T cell activation mediated by wild type HA306-318 as well as by CⅡ263-272 which was the specific T cell antigen. Conclusions This study suggests that HA306-318 peptide is antigenic and can induce responses in HLA-DR1 specific T cells. Altered HA306-318 peptide is hyporesponsive in T cell activation with inhibitory effect on antigen-driven T cell responses, and it is potentially a therapeutic agent in rheumatoid arthritis.

ObjectiveTo explore the relationship between the weight-bearing of affected side and the functional mobility in stroke patients.Methods36 hemiparetic stroke patients participated in this study. They were asked to measure the ration of the weight-bearing of affected side on the undisturbed and maximum situations, as well as the time for Timed "Up and Go" Test (TUGT) and Sit-to-Stand Test. The correlation between the ration of the weight-bearing of affected side on maximum situations and the time for the TUGT and Sit-to-Stand Test were analysed statistically with Spearman's correlation in those stroke patients whose ration of the weight-bearing of affected side on undisturbed situations was less than 50%.ResultsThere were correlation between the ration of the weight-baring of affected side on maximum situations and the time for the TUGT (r=-0.605, P<0.01) and the time for the Sit-to-Stand Test (r=-0.456, P<0.05).ConclusionA good relationship exists between the weight-bearing of affected side and the functional mobility in stroke patients.

AIM: To explore the way and the feasible time of olfactory ensheathing cells (OECs) transplanting to experimental autoimmune encephalomyelitis (EAE) rats, and to investigate the migration of OECs after transplanted to EAE and the possible mechanism of inducing the protective effect. METHODS: The Lewis rats, which were divided into MOG group and GPSCH group according to the induction by MOG~Igd and GPSCH separately, were used to made EAE model. The animals in MOG group were divided into 3 subsets: OECs blank group (MOG0 group, 4 rats );OECs transplantation by vena caudalis (MOG1 group, 7 rats);OECs transplantation by lateral cerebral ventricle (MOG2 group, 4 rats). The animals in GPSCH group were also divided into 2 subsets: OECs blank group (GPSCH0 group, 4 rats);OECs transplanted by vena caudalis (GPSCH1 group, 4 rats). OECs transplanted through different ways in peak incidence, then the rats were measured to determine whether the symptom was ameliorated. Two weeks after transplantion, the rats were killed and the methods of histofluorescence and histopathology (HE staining and Luxol fast blue staining) were used to examine the distribution of the labeled OECs in EAE rats' bodies and to explore whether there was some amelioration in histology. RESULTS: After OECs transplantation by vena caudalis or lateral cerebral ventricle, the rats' symptom improved. Compared to OECs blank groups, there was significant difference in clinical scores (F=18.470, P<0.01;t=-7.147, P<0.01). No significant difference between MOG1 group and MOG2 group was observed (P>0.05). The labeled OECs entered into the brain through the broken blood-brain-barrier after transplantation by vena caud-alis, the labeled OECs near the subpial area and around the lesions were found. OECs transplantation by the way of lateral cerebral ventricle showed great migration potential, the cells moved towards to the lesions extensively. No significant difference between OECs transplantation group and OECs blank group in histopathology (HE staining and LFB staining) was observed (P>0.05), and the same thing also happened between MOG1 group and MOG2 group (P>0.05). CONCLUSION: The transplantation of adult rats' OECs improves the EAE rats' symptom at some degree by the ways of vena caudalis or lateral cerebral ventricle.

Objective To obtain an accurate and effective method for thalamus segmentation based on resting-state functional magnetic resonance imaging (fMRI).Methods Based on the fact that resting-state fMRI technique examined spatial synchronization of spontaneous fluctuations in blood oxygen level-dependent (BOLD) signals indirectly reflect the neuronal and synaptic activity,the in-thalamus BOLD signal correlations were calculated,and then the k-means clustering algorithm was applied to obtain functional connectivity-based thalamus segmentation.Results The thalamus was divided into seven regions.Voxels within the same region were highly correlated with each other.The segmentation result was similar to that divided by functional connectivity between thalamus and the cerebral cortex.Conclusions Resting-state fMRI could provide not only the functional connectivity network between cortical and subcortical brain regions,but also the functional characteristics of thalamus.Segmentation algorithm using only internal information of thalamus shows lower computational complexity and higher processing speed than that based on the functional connectivity between thalamus and the cerebral cortex.

Objective To analyze the composition principles of Chinese patent drugs containing Rehmanniae Radix;To provide reference for clinical application and new drug research and development.Methods Based on the software Traditional Chinese Medicine Inheritance Support System (V2.0), the authors built prescription database containing Rehmanniae Radix in National Standard for Chinese Patent Drugs (NSCPD). Then the authors adopted the statistical module by using data mining methods such as association rules and improved mutual information method, with a purpose to analyze the attending disease, combination rules and the core groups in prescriptions containing Rehmanniae Radix.Results In 357 prescriptions containing Rehmanniae Radix, 17 most commonly used drug combinations were mined. Meanwhile, two diseases, namely, insomnia and vertigo were chosen from the 22 diseases that Rehmanniae Radix was most frequently used to make deeper analysis, showing that Rehmanniae Radix can achieve different therapeutic effects through different compatibility.Conclusion Prescriptions containing Rehmanniae Radixin NSCPD mainly concentrate on clear heat and cool blood, and nourish Yin. The composition principles obtained from the research that Rehmanniae Radix used when curing different diseases can fully play the efficacy of RehmanniaeRadix and provide evidence for clinical scientific formulae.

Objective To study the effects of physical training on baroreflex sensitivity (BRS) by monitoring finger arterial pressure among volunteers who had experienced three-months′ aerobic or anaerobic exercises.Methods A total of 16 healthy men were divided into the aerobic exercise+anaerobic exercise group (group A,n=7) and aerobic exercise group (group B,n=9).Each subject was trained for 12 weeks.Head-up tilt (HUT) table test was performed before and 4,8,and 12 weeks after training.Blood pressure,finger arterial pressure and electrocardiogram (ECG) were compared between the two groups.Results The BRS was significantly increased after training in group A,although no changes were found in group B.Conclusion Three-months′ aerobic exercise+anaerobic exercise seems to enhance the BRS; however,three-months′ aerobic exercise may decrease the BRS.

PurposeHeroin addiction is a chronic and recurrent functional brain disease, there are some functional changes in specific brain regions, but the network character remains unclear. The aim of this paper is to explore the network character of brain resting-state functional network in heroin addicts, to identify the potential neuromechanism of heroin addiction from the perspective of brain network.Materials and Methods Thirty heroin addicts (HA group) and twenty-nine healthy controls (control group) underwent resting-state functional MRI scanning using GE 3.0T MRI scanner. The brain functional networks were constructed based on graph theory, the small-world properties and node properties were calculated and compared between the two groups, the correlation between the total dosage of heroin and node degree was analyzed.Results Compared with control group, the small world characteristics of HA group was altered with statistically significant difference (P<0.05, corrected by false discovery rate); the node degrees in orbit frontal regions increased, while those in occipital brain regions decreased (P<0.05, corrected by false discovery rate). No correlation was found in HA group between node degree and the total dosage of heroin.Conclusion These results suggest that topology of functional brain networks were altered in heroin addicts which tends to random networks; increased motivational driving to the salience of drug and decreased visuospatial attention in heroin addicts may provide a strategy for identifying the neuromechanism of heroin addiction.
