Objective: To study the effect of photosynthetic bacteria (PSB) on serum lipids and antioxidant capacity. Methods: The rabbits were fed high lipid diet to induce hyperlipidemia. The effect of PSB on hyperlipidemia was studied with Spirulina platensis as the positive control. The content of serum TC, TG , HDL-C, SOD activity, and the content of GSH, LPO were determined. Results: PSB could significantly reduce the content of TC,TG , LDL-C in serum, increase H/L and decrease AI ratio. Meanwhile, PSB could improve antioxidant capacity, as greatly increase blood SOD activity, GSH in blood and liver, and reduce serum LPO. In comparison, PSB was better than Spirulina platensis. Conclusion: PSB can significantly regulate lipid metabolism and improve antioxidant capacity in hyperlipidemic rabbits.

Objective: To study the prevention and treatment of photosynthetic bacteria (PSB) on atherosclerosis (AS). Method: The hypolipidemic effect of PSB on atherosclerosis (AS) in rabbits induced by high cholesterol diet was studied with Spirulina platensis as positive control. The content of liver TC,AS plaque area percentage (PA) and the emphraxis of coronary artery were determined. Results:PSB could significantly reduce the content of TC in liver, the liver index (LW/BW), and PA 63.99%, 21.96%, 70.10%, respectively, and remarkably abate the lipid aggregation in liver and the pathological changes of coronary artery. In comparison,PSB was better than Spirulina platensis. Conclusion:PSB can prevent the formation of atherosclerosis in hyperlipidemic rabbits.

Liver biopsy plays an important role in the diagnosis of autoimmune liver diseases,particularly in patients without specific clinical manifestations or negative for autoantibodies.The histological features of several autoimmune liver diseases are reviewed.The characteristic features of autoimmune hepatitis in histology include interface hepatitis with lymphoplasmacytic infiltration,hepatic rosette formation,and emperipolesis,while chronic nonsuppurative destructive cholangitis and epithelioid granuloma are frequently found in primary biliary cirrho-sis.Primary sclerosing cholangitis is characterized by onion skin-like periductal fibrosis,while storiform fibrosis with IgG4-positive plas-ma cell infiltration often indicates IgG4 -related sclerosing cholangitis.Enhanced communication between clinicians and pathologists can help improve the diagnosis and treatment of autoimmune liver diseoses.

[ABSTRACT]IL-13isapleiotropiccytokinemainlysecretedbyactivatedTh2cells.Ithas2receptors,IL-13Rα1 and IL-13Rα2.The latter had been thought to serve exclusively as a decoy receptor for a long period of time due to its short cytoplasmic tail and lack of signal transduction structure .Since Fichtner-Feigl reported in Nature Medicine that IL-13 is in-volved in induction of TGF-βproduction and tissue fibrosis through IL-13Rα2-mediated signaling pathway , it was found that IL-13Rα2 has more sophisticated functions than just a simple decoy receptor as more and more researches have explored its signaling functions .This review combines the most advanced research results with previous investigation and discusses the gene structure, expression, production, distribution, subtype conversion and possible signal pathways mediated by this re-ceptor.More importantly, the connection with human diseases and the applications in disease diagnosis and molecule targe -ted therapy for cancer are also discussed .

Objective To develop an ELISA for detection of anti-dsDNA antibody by using plasmid DNA as antigen.Methods DNA in plasmid pBV220 for prokaryotic expression vector was purified by base-cleavage. The microtiterplates were pretreated by poly-L-lysine and coated by the plasmid DNA in a dilution of 1∶50 as antigen. An ELISA method for detection of serum anti-dsDNA antibodies was developed with HRP-SPA as enzyme-labeled marker.The IIF using crithidia lucilia as substrate was performed simultaneously for comparison. The serum samples from 64 patients with SLE, 8 with MCTD and 17 with RA were detected. Results The concentration of DNA was 1 54 g/L by UV spectrophotometer at wavelength of 260 nm. The positive percentage of ELISA for anti-dsDNA was higher than that of IIF. By comparison with IIF the positive percentages in SLE, MCTD and RA groups were 23 4% vs 17 2%, 12 5% vs 12 5% and 11 8% vs 5 9%, respectively, and the coincident rates between the 2 methods were 93 8%, 100% and 94 1% respectively. The sensitivity and specificity of the developed ELISA for detection of anti-dsDNA were 100% and 93 4% when IIF was as gold standard.Conclusion The ELISA by using plasmid DNA as antigen to detect anti-dsDNA has fine precision, sensitivity and specificity. Its positive rate is higher than that of IIF thus it will contribute to monitor the activities for SLE patients′ condition.

Objective To acknowledge the present status of clinical use of nonsteroidal antiinflammatory drugs(NSAIDs) in China. Methods Five hundred and seventy-five valid questionnaires were collected from 50 hospitals in different areas of China including Shanghai, Beijing, Tianjin, Shenyang and Guangzhou. Results 54.7% of doctors used cyclooxygenase-2 (COX-2) selective inhibitors. The ratio of the doctors prescribing loxoprofen, diclofenac, meloxicam were 22.6%, 23.3%, 14.60%, respectively. The ratio of the doctors who prescribe uncoated routine-dose aspirin, uncoated low-dose aspirin, enteric-coated routine-dose aspirin, enteric-coated low-dose aspirin and others were 17.0%, 14.7%, 36.8%, 28.5% and 3.0%, respectively. The ratio of doctors who only "some-times" prescribed co-medicine to prevent gastrointestinal damages when they prescribed aspirin, conventional NSAID and COX-2 selective inhibitors were 41.10%, 40.70% and 45.1%, respectively, while the most commomly used co-medicine were H2 receptor antagonist (H2 RA) and proton pump inhibitor respectively. 37.1% of doctors examined H. pylori infection status, and 76.3% of doctors would eradicate H. pylori if positive. Conclusions The most commonly used conventional NSAID is diclofe-nac. The most commonly used formulation of aspirin is enteric-coated aspirin. Most doctors only "sometimes" prescribe co-medicine together with aspirin, conventional NSAID and COX-2 selective inhibitors to prevent gastrointestinal damages, and the most commonly used co-medicine is acid inhibitor. Only a few doctors examine H. pylori infection prior to the administration of NSAID.
