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

The thermostability of the inulinase was studied in this resea rc h. Some alcoholic materials and thickening agent could enhance the thermostabli lity of the inulinase. Using glycerol、xanthic pastern and though orthogonal ex periments of three elements and three levels, a satisfying protective agent, whi ch included glycerin(6%), xanthan gum(0.6%) and CaCl_2 (100mmol/mL) and ha d a significant effect on the enhancement of the inulinase thermostability, was acquired.

Objective To explore the effect of carvedilol on ACE2 gene and protein expression in chronic heart failure rats after myocardial infarction.Methods The heart failure model was induced by acute myocardial infarc- tion (AMI) through ligating the left anterior descending coronary artery.One month after operation,rats were randomized to receive placebo or carvedilol 2 mg/(kg?d),by gavage.Sham-operated rats were used as the control group.Hemodynamies,body mass and left ventrieular mass index,plasma and myocardial level of angiotensin Ⅱ were determined.ACE2 gene and protein expression was assessed by using RT-PCR and Western Blot.Results The mortality of placebo and Carvedilol groups were 20%,compared with 0% in sham operated rats.Carvedilol significantly improved LVEDP,LVSP,+dp/dt_(max) and-dp/dt_(min) in CHF rats but all the hemodynamics data were still inferior than that of controls.Plasma and myocardial angiotensin Ⅱ level were increased significantly in CHF placebo rats than those of control rats (plasma Ang Ⅱ:CHF:194?19 vs controls:132?15 ng/L,myocardium Ang Ⅱ:CHF:6.7?0.4 vs control:3.8?0.3 ng/g,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.
