Objective To investigate gut barrier dysfunction and bacterial translocation (BT) from gastrointestinal tract in postoperative patients using polymerase chain reaction (PCR) and plasma D-lactate measurement, and to study the relationship between BT and infections complications. Methods 34 patients undergoing selective gastrointestinal operations were observed. Blood samples were collected prior to and 2, 24, 48 h after surgery for bacterial culture, plasma D-lactate, and LPS measurement. PCR was used to detect microbial DNA. PCR was performed after DNA extraction, with target ?-lactosidase gene of E. coli and 16S rRNA gene of most pathogenic bacteria. All the patients were observed for 30 days for monitoring infectious complications. Results No bacterial DNA was detected before surgery, but it was positive in 7 patients (20.6%) after operation. Bacterial DNA was discovered in 38.9% (7/18) of SIRS (systemic inflammatory response syndrome) patients, no bacterial DNA was detected in the 16 non-SIRS patients (P

Objective To determine the kinetic changes of plasma D-lactate and endotoxin levels in patients after intraperitoneal operations. Methods Blood samples of 63 patients undergoing selective laparotomy were collected 0, 2, 24 and 48h after surgery. According to various criteria, the patients were divided into two groups respectively, i.e. extensive operation or medium sized operation,involvement of gastrointestinal (GI) tract or non-involvement GI tract, and development of symptoms of SIRS or no SIRS after operation. Plasma levels of D-lactate and endotoxin in systemic circulation were determined. Results The analytical data showed that the plasma levels of D-lactate and endotoxin were elevated significantly at 2, 24 and 48h post laparotomy in SIRS patients and major surgery group, and there was also a significant correlation between the plasma levels of D-lactate and endotoxin(?=0.91,P

The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

A comparative study on the glycolic acid oxidase (GO) of the domestic Spirulina(Arthrospira) platensis (S_(1)) from alkaline lake in Erdos Plateau and the imported S. (A.) platensis (S_(2)) and S. (A.) maxima (S_(3)) as well is made with colorimetric method. The results show that activity of GO (25℃, pH 8.0) of S_(1), S_(2 )and S_(3) is 70.9 U/gFW, 59.6 U/gFW and 80.9 U/gFW respectively; the GO's optimum temperature of S_(1)、S_(2) and S_(3 )is 30℃; the GO's optimum pH value of S_(1 )is 8.6,while that of S_(2 ) 8.2 and that of S_(3) 8.4; the GO of S_(1 )is stable from 0℃ to 35℃ and from pH 7.6 to pH 10.0, while that of S_(2) from 0℃ to 30℃ and from pH 8.0 to pH 9.0 and that of S_(3) from 0℃ to 35℃ and from pH 8.0 to pH 8.6. Adaptive range of S_(1) GO for temperature and pH is wider, and activity at low and high temperature and under strong acidand alkali conditions is higher than that of the imported species.

Objective To evaluate the efficiency of primary hepatic carcinoma(PHC)using tran- scatheter arterial chemoembolization(TALE)combining with MSC.Methods Treatment group(30 patients with unresectable PHC)adopt MSC after TALE,while control group(10 patients with unresectable PHC)only adopt TALE,then observing the curative effect and survival rate.Results One year after treating,the local effect was 90 %,60 %,1～2 year survival rate was 90 %,30 % respectively,median life span was 15 months. Conclusion To treat PHC with TALE combining with MSC is an effective and non-invasive method.

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

Objective Implanting surgical meshes to support breast in periareoler mammaplasty shows an excellent prospect.But shrinking of the mesh and the adhesion formation affected the postoperative shape and palpation of the breast.The aim of this study was to compare biocompatible properties of four different polypropylene meshes (Prolene(R) ; Vypro Ⅱ(R) ; Premilene Mesh (R) and Premilene Mesh LP(R)) and to discuss the inclusion criteria of meshes in this technique.Methods The study was carried out in pigs.Four different polypropylene meshes were implanted subcutaneously in belly.90 days after implantation the mesh samples were explanted,and complications,foreign-body reaction,collagen fiber and elastic fiber formation were observed,as well as ultrastructures for the biocompatible properties.Results The biocompatible properties of each mesh were different.The foreign-body reactions determined the biocompatible properties,and affected the postoperative shape greatly.Conclusions Premilene Mesh LP o as a newer low-weight polypropylene mesh,has superior properties to the others.
