Autoimmune diseases (AID) are characterized by autoimmune disorder, as autologous tissue is attacked by the autoimmune system. It is reported that the imbalance of autoimmune tolerance and ingrained inflammatory response are the core events of AID undoubtedly. Peroxisome proliferator-activated receptor γ (PPARγ) which belongs to the nuclear hormone receptor superfamily is a ligand activated transcription factor. PPARγ combines with retinoid X receptor (RXR) to form heterodimer. When PPARγ is activated, the complex regulates gene expression by binding to a specific peroxisome proliferator response element (PPRE). In addition, PPARγ has diversified biological functions, playing important roles in regulating metabolism, controling inflammation, modulating glucose and lipid metabolism, ameliorating atherosclerosis, anti-tumor, and regulating immune response. However, recently researches indicate that PPARγ participates in the pathogenesis of AID. PPARγ plays key roles in regulating activation and polarization of macrophages, function of dendritic cells, proliferation and differentiation of T cells, and modulation of the function of related stromal cells. This article summarizes the biological functions and signal transduction pathways of PPARγ and the protective effects of agonists of PPARγ on AID, aiming to provide theoretical support for the research of mechanism and prevention and treatment of AID.

Objective: To explore the structural domains of the CENP-E protein that interact with Mps1 protein.Methods: Two recombinant vectors named pEGFP-CENPE2(containing 674-1085 amino acids of CENP-E protein) and pEGFP-CENPE 3(containing 1200~2134 amino acids of CENP-E protein) were transfected into human embryo kidney 293(HEK293) cells respectively.The respective energy transfer efficiency(Ef) between either EGFP-CENPE2 and Mps1,or EGFP-CENPE3 and Mps1 were detected by FRET through selective photobleaching of the acceptors.Results: Both recombinant proteins expressed in HEK293 cells transfected by the recombinant plasmids were found to co-localize with the Mps1 protein as confirmed by confocal microscopy.The Ef between EGFP-CENPE3 and Mps1 protein was [(12.63?0.48)%,n=30] and that between EGFP-CENPE3 and Mps1 protein was [(3.17?0.21)%,n=30] as revealed by the results from FRET,the result of FRET was confirmed by co-Immunoprecipitate(CO-IP) method.When compared with that between the control and Mps1,the Ef between EGFP-CENPE3 and Mps1 was significantly higher(p

Objective To evaluate the PDCA cycle on the rehabilitation of postoperative patients with anal fistula, aiming at improving the recovery of patients and preventing recurrence. Methods 144 postoperative patients of anal fistula were randomly divided into the observation group and the control group with 72 cases in each group. The observation group received intervention based upon the PDCA cy-cle, and the control group was given the traditional oral propaganda. The recovery time, recurrence rate, mastering of education content and self-control ability were compared in the two groups using t test and χ2 test. Results The mastering level of education content and the self-management skills in the observation group were superior to those of the control group. After 3 to 24 months of follow-up, the observation group showed shorter recovery time and less recurrence rate than that of the control group. Conclusions Nurs-ing intervention based upon PDCA cycle can strengthen the patients' mastering of related knowledge, pro-mote the recovery, reduce recurrence rate and improve the patients' quality of life.

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8～12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16～3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.

AIM: To explore the characteristic of relaxation of porcine cornea after LASIKMETHODS: Usual LASIK was performed on fresh porcine corneas with stable intraoculer pressure (IOP) maintained through optic nerve irrigation. The ablation depth on stroma is 30%, 50% and 70% respectively. Then the dumbbell-shaped corneal strip specimens were cut and stored in 20% Human Albumin solution for use (4℃).Sip up the Albumin solution on specimens, and fixed them on homemade jig. Stress relaxation tests were erformed on Tytron250 Dynamics Experiment System. the loading speed was 385mm/min,extending ratewas 1.5, and relaxation time was 1 000s. The data werecollected electronically and automatically.RESULTS: In LASIK procedure, though a single flap-cutting can cause a little reduction of corneal stress relaxation (P＜0.05,P=0.49), the cornea may still remain its property of visco-elasticity. When ablation depth was 30% or more, corneal stress relaxation decreased to almost one half (P＜0.01).The change of corneal stress relaxation degree in vertical meridian specimen was lower than that in horizontal specimen, especially when ablation depth was 70%, and it's statistically significant (P＜0.001). In LASIK operation, the more depth the ablation, the more reduce the stress relaxation degree, and it's easy to cause deformation and creep deformation.CONCLUSION: The changes of the stress relaxation in verticai and longitudinal meridian specimens are similar, and slightly obvious in longitudinal specimen, especially in 70%ablation group.
