BACKGROUND:As a material to repair osteochondral defect,the acellular cartilage matdx has attracted more and more researchers'attention,however,there is no comparison between two ways of decelluladzation.OBJECTIVE:To test trypsin and Triton X-100 methods for their potential of cell removal.DESIGN,TIME AND SETTING:Controlled observation was performed at the Central Laboratory of Orthopaedics in the Second Hospital of Shanxi Medical University between March and July in 2008.MATERIALS:Fresh knee and hip articular cartilages of pig were purchased from the market.METHODS:Porcine articular cartilages were treated with either 0.25%trypsin or 0.25% Triton X-100 respectively for decelluladzation,while fresh untreated articular cartilage served as control.MAIN OUTCOME MEASURES:①General observation on the morphology of acellular articular cartilage.②Immunohistochemistry and scanning electron microscopy were used to determine the effect of two decellularization methods on the extracellular matrix collagen.③Ten articular cartilage leaflets in each group were measured for breaking strength and percentage elongation through loading,unloading and breaking tests.RESULTS:①By use of trypsin and Triton X-100 methods,the acellular matrix had no significance difference in the morphology compared with untreated cartilage,only presenting slightly white color and feeling less soft.②lmmunohistochemistry and scanning electron microscopy results showed that,trypsin and Triton X-100 methods achieved complete decelluladzation.Trypsin had no significant influence in extracellular matrix and cartilage leaflets microstructure;Triton X-100 caused some tiny structural alterations,such as more collagen and disordered structure.It is possibly that Triton X-100 damaged extracellular matrix.③No significant difference was identified between untreated and trypsin,Triton X-100 groups in breaking strength and percentage elongation.CONCLUSION:Trypsin and Triton X-100 all achieve complete decellularization.but trypsin uses short time and low costs with well preservation,while Triton X-100 with long procedure and slight damage to collagen structure.They all have no significance influence to the mechanics characteristics of articular cartilage.

Objective To investigate the relationship between air pollutant exposure and preterm delivery (PTD) by Logistic regression model, as the effect of air pollutant exposure to PTD made great concern today. Methods The present study consisted of 31 145 qualified birth cases, 80.09% of the total amount, from 1 Nov, 2005 to 1 Aug, 2007. The covariant items included maternal age, nation, education, residence, income, occupation, occupation exposure, parent-drinking, father-smoking, heating-type, folic acid supplement, season of pregnancy, prenatal health care, etc. The Logistic regression analysis was employed to control the confounding factors mentioned above, then the pollutant was introduced step by step to build the single, double and triple pollutant Logistic regression model to examine the association between three pollutants (SO2, NO2, and PM10) and PTD during the first and third trimesters of pregnancy. The air monitoring data (daily average of SO2, NO2, and PM10) were collected from Taiyuan Environmental Monitoring Station. Results In the first trimester, a quartile increase of NO2 exposure caused the risk for PTD increased by 22.7%. As for the effect of PM10, no significant differences were seen. In the third trimester, a quartile increase of NO2 exposure caused the risk for PTD increased by 19.1%. Conclusion The NO2 exposure during the pregnancy can increase the risk of PTD. The susceptible exposure-window choice is critical for the further study in this field.

Abstract To analyse the mechanism of TECA bio-artificial liver support system(BALSS)to treat acute liver failure (ALF) canines. The blood of partial liver resection-induced ALF canines or RPMI1640 solution were circulated in the inner space of the hollow fibers (blood loop), and porcine hepatocytes were cultured in outer space of the hollow fibers (cell loop). The concentrations of lidocaine, albumine and urine in the RPMI1640 solution were measured. The compositions of proteins in cell loop and blood loop were analysed by polyacrylamide gel electrophoresis (PAGE). The ultrastructure of porcine hepatocytes in BALSS was observed with transmission electronic microscopy. There were not any proteins in RPMI1640 solution before BALSS circulation. After 6 hours of the BALSS circulation, the concentration of lidocaine in RPMI1640 solution decreased significantly,and concentration of albumine and urine nitrogen increased gradually. The ultrastructure of the porcine hepatocyte shown damaged after BALSS 6h. The results suggested that TECA BALSS could replace temporarily the functions of failure liver by the effects of biologic transform and synthesis of porcine hepatocytes.
