Objective To explore the role of kidney interstitial dendritic cells in irnmunodissonance moechanism in mice with multiple organ dysfunction syndrome(MODS).Method The model of MODS wasmade by injecting zymosan into the peritoneal caiecty of C57BL/6 miee,and the mice were randomly divided into 5 groups,namely,normal,3～6 hours,12～48 hours,5～7 days,10～12 days after administrating zymosan. Pathological changes of kidney interstitial dendritic cells were observed by transmission electronic microscopes. Specific sudaee markers CD205,CD11e,CDSO,MHCⅡmolecules I-A~b,CD4~+ and CD8~+T lymphocyte subgroups in peripheral blood were detected by immunohistochemistry and flow cytomctry.Results In acute injury stage,in comparison with normal group,interstitial dendritic cells had a continuous proliferation with high expression of CD80 and I-A~b(P

Objective To assess the efficacy and safety of various spectrum lasers in the treatment of acne vulgaris. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Library (2009, 6 issues), PubMcd, Embase, China Biomedical Literature Database, China Journal Full Text Database, Chinese Scientific Journals Full Text Database. Retrieval time was up to June, 2009. Randomized controlled trials (RCTs) of lasers for acne vulgaris were included. Results Twelve RCTs totaling 367 patients were included. Because the lack of clinical homogeneity, only descriptive analysis was conducted. Acne lesion counts improved significantly with laser therapy. Adverse effects were limited to transient erythema and edema at treatment sites. Treatment-related pains were well tolerated. Conclusions Current evidence demonstrates that all type lasers in treating acne vulgaris is safe and efficacy. However, higher quality RCT research would be needed to verify the effects and status of lasers on acne vulgaris.

Objective To explore the effect of Qingkailing on the distribution and contents of neuropeptid Y(NPY)in hippocampus of epileptic rats.Methods Adopt abdominal cavity injection pentetrazole was used to establish the model of epileptic rats.Then content of NPY was assayed by radio-immunity and the distribution was observed by immunohistochemistry.Results The content of NPY in kindling group was significantly higher than that in control group(P

Hepatitis B virus (HBV) is a major cause of chronic liver disease, and frequently results in hepatitis, cirrhosis, and ultimately hepatocellular carcinoma. HBV polymerase (Pol) is an essential viral protein that is important for HBV replication and might be involved in the development of hepatocellular carcinoma. Protein-protein interactions appears to be crucial for its role. The aim of this study was to screen and identify the proteins that interact with Pol using a co-immunoprecipitation-based LC-MS/MS identification technique. The HBV Pol gene was amplified by polymerase chain reaction (PCR) and cloned into pCDNA3.1(+). The recombinant plasmid pCDNA3. 1(+)-Pol-flag was transfected into HeLa cells. Liquid chromatography and tandem mass spectrometry (LC-MS/MS) identified 45 proteins that co-immunoprecipitated with flag-tagged HBV Pol. Eleven of these have previously been reported as proteins that interact with HBV Pol. A proof-of-concept-based Ingenuity Pathway Analysis (IPA, www.ingenuity.com) was used to characterize the functions and pathways of these 45 identified proteins and HBV Pol. Among these proteins, four proteins may play a role in three major molecular cellular networks, and are therefore worthy of further investigation.
