Synthetic agonists of peroxisome proliferator-activated receptors-?(PPAR?) have an important role in the preclinical models of metabolic diseases.In the recent years,it has been demonstrated that PPAR? agonists can normalize blood lipids and reduce insulin resistance and adiposity in rodents and primates.PPAR? activation in the skeletal muscle regulates the oxidative capacity of the mitochondrial apparatus,switches fuel preference from glucose to fatty acids and reduces triacylglycerol storage.PPAR? agonists also reduce insulin levels in serum,increase the sensitivity of insulin and improve glucose-tolerance.The genetic polymorphism in PPAR? has been shown to be associated with blood lipids,obesity and type 2 diabetes.

Objective To study the antagonism of water-soluble compounds of salvia-salvianolic acid A(SalA),salvianolic acid B(SalB) and catechu aldehyde(CA) to Cr(Ⅵ) induced genetic toxicity in Vicia faba root tip cells.Methods The root tip of Vicia faba were treated with SalA,SalB,CA(5-1000 ?g/ml) and every compound combined with 100 ?g/ml Cr(Ⅵ) respectively,and with distilled water as control group.The micronucleus rate(MNR),the mitotic index(MI) and the chromosome aberration rate(CAR) of Vicia faba root tip cells were observed by micronucleus assay and chromosome aberration assay.Results Compared with control group,treatments of 50,100 ?g/ml SalA,50 ?g/ml SalB,100,500 ?g/ml CA significantly increased MI(P

Paraneoplastic pemphigus (PNP) is an autoimmune mucocutaneous disease first named by Anhalt, et al. in 1990. The disease is characterized by such distinctive clinical symptoms and signs as severe, painful mucosal erosions, polymorphous skin lesions, histopathology hallmarks, and immunological findings. The situation typically presents in patients with lymphoproliferative diseases and primarily malignancies. A main challenge of the study is the relationship between the existence of associated tumors and the autoimmune reaction to the skin. Some researchers suspected that the possible expression of foreign antigens on the tumor can cross react with epidermal antigens inducing the auto-reactive clones of T-lymphocytes. Some speculated that the type of tumors associated with PNP may produce plakin proteins that result in initiation of the immune response. Other reports believed the autoimmune reaction is related to the epitope spreading or to the changing of cytokines. We analyzed 12 PNP patients diagnosed in our department in the past few years. An intensive study to the B cells in the PNP associated with tumors demonstrated that the tumors have structural basis to produce antibody. The similar immunoglobulin heavy chain genes of tumor B-cells in 7 patients strongly suggested that the B cell clones were functional and recognized the same antigen epitope. The autoantibodies secreted by the tumor can react against specific plakin proteins in epidermis, lead to the impairment of cell-cell adhesion, and cause the mucocutanous lesions. The clinical significance of the results indicates the importances of early finding and total resection of the associated tumors, and the usage of IVIG pre or during operation to prevent Bronchitis Obliterans. The new finding is also important for the study of other antibody mediated autoimmune diseases.

Eukaryotic elongation factor 2 kinase (eEF2K) is well known as a Ca2+/calmodulin (CaM)-dependent kinase. eEF2K catalyzes the phosphorylation of eEF2 and subsequently inactivates eEF2 by impairing its ability to bind to the ribosome, thereby negatively modulates protein synthesis. The high expression of eEF2K has been found recently in several types of malignancies. As participating in the progress of tumor, eEF2K emerges a potential target for future cancer therapy. The relationship between eEF2K and tumor, and the latest progress of eEF2K inhibitors were summarized in this article.

Objective] To explore the nursing method and effect of traditional Chinese medicine wet compress for the treatment of the disease of the blood vessel. [Method]Selects the hospital March 2013 to January 2015 ,a total of 96 patients with confirmed thrombotic occlusion vasculitis with the first period and the second period of patients, who were randomly divided into treatment group and control group, 48 cases in each, two groups at the same time, the routine nursing and the context of Mailuoning 30ml IV drip, treatment group based on the Tougu Tongmai Recipe wet applied external treatment, combined with TCM syndrome nursing. Two groups for 1 month for a course of treatment, observation of cold pain in the limbs, gap of claudication, soreness and numbness symptoms and treatment of total efficiency; readmission after followed up to observe the recurrence(deterioration), statistical analysis of parallel. [Results] The total effective rates of treatment group and control group were 95.8% and 68.75% respectively, the difference was statistically significant(P<0.05); the difference between the two groups was statistically significant(P<0.05); the difference between the two groups was statistically significant(P<0.05). [Conclusion] Compared with Mailuoning injection in the treatment of, Speranskia through vein wet compress external treatment nursing can effectively improve the thrombus occlusive vasculitis in patients with limb peripheral blood circulation, also can better reduce the recurrence rate, slow the progression of the disease, so as to achieve the purpose of disease treatment.

BACKGROUND:The precise pathogenesis of recurrent aphthous ulcers remains controversial in present medical science. Oxygen free radical increase in the body is one of the causes of recurrent aphthous ulcers. OBJECTIVE:To observe the effects of superoxide dismutase on the therapeutic effect of recurrent aphthous ulcers. METHODS:After establishing 24 rabbit models of recurrent aphthous ulcers, they were randomly assigned to three groups. Model control group as a contrast was not treated. Rabbits in the negative control group were cleaned with iodoglycerin in local region daily. Rabbits in the superoxide dismutase group were intragastricaly administered with superoxide dismutase capsule solution. Local ulcer was cleaned with iodoglycerin. One week later, tissue with oral ulcer lesions was obtained and compared. In each group, after model establishment, blood was colected from rabbit ear vein at the same time in the morning every 4 days. Flow cytometry was used to analyze the changes in T cel subsets CD3+, CD4+, CD8+, and CD3+/CD8+. RESULTS AND CONCLUSION: When the ulcer lesions formed, peripheral blood CD3+, CD4+, CD4+/CD8+ ratio through statistics was apparently lower than normal levels in the model control group and negative control group. However, the number of CD8+ cels was greatly more than normal value. In the superoxide dismutase group, after administrated with superoxide dismutase capsule, the number of CD3+ and CD4+ cels was gradualy increased, but the number of CD8+ cels showed a decreased trend. These data suggested that natural scavenger superoxide dismutase using oxygen free radical can effectively scavenge excessive oxygen free radical in the ulcers, resulting in treatment of recurrent aphthous ulcers.

Objective Percutaneous coronary intervention( PCI) is effective in improving the ischemia and prognosis of pa-tients with acute myocardial infarction ( AMI) to reduce the short-term mortality.However, little research has been done on PCI in eld-erly AMI patients.The study aimed to evaluate the efficacy and the safety of percutaneous coronary intervention in elderly AMI patients (≥75 years old) . Methods 213 AMI patients who underwent emergency PCI in Jingling Hospital from January 2012 to December 2013 were divided into 2 groups:elderly group (≥75 years old, n=57) and non-elderly group (<75years old,n=156).Retrospec-tive analysis were made on the clinical data and the coronary intervention features of the patients. Results There were more patients having dyspnea, fatigue and other heart failure symptoms at the onset of first-break AMI in elderly group than in non-elderly group (21.1%vs 3.2%,P<0.0).More women (47.4% vs 16.7%,P<0.01) and more patients with hypertention or diabetes mellitus were found in elderly group.The procedure success rates with TIMI-3 flow grade of post-PCI in both groups were very high (100%). Compared with non-elderly group, the occurrence of the procedure-related complications (3.5%vs 2.6%,P=NS) and major adverse cardiac event rates (8.8%vs 6.4%,P=NS) and in-hospital mortality (5.3%vs 2.6%,P=NS) showed no significant difference.Conclusion There are more atypical clinical symptoms in elderly AMI patients. The emergency PCI in elderly AMI patients can effectively make artery unimpeded with high successful rate, few com-plications and a favorable short-term prognosis.
