Aim The effects of antibiotics and anticoagulants on mouse peritonaeum were ob-served to explore the factor of the peritoneal dialysis related sclerosing peritoni-tis. Methods The experimental models of peritoneal dialysis were established in miceby infusing different kind of drugs to the peritoneal cavity and the changes of the peri-toneal membrane for each drug at different time were observed by the autopsy and lightmicroscope for several weeks. Results Amikacin, Cefradine, Zinacef, Ciprofloxacin,Heparin and Urokinase could induce sclerosing changes of peritoneal membrane such asloss of peritoneal mesothelum infiltration of inflammatory cells and of proliferation fibrecell.These changes were irreversible after the drugs were stoped.Conclusion Thedrugs commonly used in peritoneal dialysis may in different degree result in peritonealsclerosis.

Objective To evaluate the relationship between Henoch-Schonlein purpura (HSP) accompanying renal impairment and helicobater pylori(Hp) infection.Methods This study consisted of 304 patients with HSP.The patients were divided into 2 groups(group A and group B) based on Hp infection or not(91 cases in group A and 213 cases in group B).Compared with the rates of accompanying renal impairment in 2 groups.And observed the recovery from renal impairment between the patients who were turned into negative(group C)and patients still were positive after the anti-Hp therapy(group D).Numeration data were analyzed by ?2 test.Results Group A which was with Hp infected,the accompanying renal impairment ratio was 65.9%.Group B which was without Hp infected,the ratio was 35.2%.There was significant difference between 2 groups(?2=24.378 P

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

Most drugs need to interact with cell membrane to reach the biological target, so that membrane affinity assay is an important early screening step in drug discovery. However, at present, the traditional oil-water distribution method is still used, a new, simple and accurate method for membrane affinity assay is urgently needed. In this study, according to the colorimetric principle, a new assay model based on polydiacetylene vesicles was optimized through a series of experiments including different concentrations of vesicle solution, temperature, or pH reaction environment. On this basis, tetracaine hydrochloride, 2-methylimidazole and histamine were used as model drugs to measure the membrane affinity constants and verify the between-batch precision of the optimized assay model (relative standard deviation less than 5%). In addition, polydiacetylene vesicles were stable for up to 180 days, demonstrating the potential application of the assay model. This strategy is simple, stable, reliable, with high reproducibility, low cost and easy to promote, which provided a new tool and a new direction for the high-throughput assay of membrane affinity.

Objective To investigate the clinical value of detecting the serum level of ryanodine receptor antibodies (RyR-Ab) in the diagnosis and evaluation of myasthenia gravis (MG). Methods Enzyme-linked immunosorbent assay (ELISA) and Western blotting were used to detect the serum level of RyR-Ab in 81 patients with MG, 45 non-MG patients with other neurological disorders and 50 healthy control subjects. Results The results of ELISA showed a serum RyR-Ab positivity rate of 23.4% in the in MG patients, significantly higher than the rates in non-MG patients and the healthy subjects (P<0.05). The serum RyR-Ab positivity rate was 77.2% in MG patients with thymoma (MGT), 14.2% in those with thymie atrophy (MGA), and 6.6% in those with thymie hyperplasia (MGH). A positive correlation was found between the titer of serum RyR-Ab and the severity of muscle weakness (r=0.547, P<0.05). Compared with CT scanning, serum RyR-Ab level had low sensitivity (77.2%) but high specificity (91%, P<0.05) for diagnosis of MGT. According to the results of Western blotting, the serum RyR-Ab positivity rate was 81.8% in MGT patients, significantly higher than that in thymomβ-free MG patients and NMG patients (P<0.05). Conclusion RyR-Ab positivity is mainly found in MGT patients, and detection of serum RyR-Ab may help evaluate the severity of MG and assist in CT-based diagnosis of MGT.
