Objective To study the value of serum galectin-3 detected by nanomagnetic beads sorting time resolved fluoroimmunoassay (TRFIA) tandem analysis in the diagnosis of pancreatic cancer.Methods The serum of 88 cases of pancreatic cancer,50 cases of acute pancreatitis,10 cases of pancreatic cysts,and 20 cases of healthy volunteers as control were collected.First,galectin-3 antibody coupled nanomagnetic-beads was used to sort the semm,then TRFIA was applied to detect the level of galectin 3,and the result was compared with that of routine TRFIA.ROC curve was constructed to determine the cutoff value and sensitivity for pancreatic cancer diagnosis.Results The method of nanomagnetic beads sorting TRFIA detected the level of galectin 3 between O.78 and 100 ng/ml in a linear manner,the intra-CV was ≤6.38％,and inter-CV was ≤7.22％,and average recovery rate was 105.3％.The serum level of galectin-3 in control group by nanomagnetic beads sorting TRFIA was 0.38 (0.02 ～ 3.06) ng/ml,which was significantly higher than that detected by routine TRFIA [0.18 (0.00 ～ 2.64) ng/ml,P =0.000).The serum levels of galectin-3 by nanomagnetic beads sorting TRFIA in pancreatic cancer,acute pancreatitis,pancreatic cysts and healthy volunteers were 4.85(0.00 ～42.67),0.69(0.00～ 13.62),0.70(0.00 ～ 14.54),0.38(0.02 ～ 3.06) ng/ml,and the level of galectin-3 in pancreatic cancer was significantly higher than that in acute pancreatitis,pancreatic cysts and healthy volunteers group (P ＜0.01),while the difference among the other three group was not significantly different.The AUC of galectin-3 for pancreatic cancer was 0.851 ± 0.040,95％ CI:0.772 ～ 0.929.While using 1.07 ng/ml as the cut-off value,the positive rates for the diagnosis of pancreatic cancer,acute pancreatitis,pancreatic cysts and healthy volunteers were 84.1％ (74/88),34.0％ (17/50),20.0％ (2/10),10.0％ (2/20),and the sensitivity for diagnosis of pancreatic cancer was significantly higher than those in other 3 groups (P ＜ 0.01).Conclusions Nanomagnetic beads sorting TRFIA tandem analysis method can enrich serum galectin-3,and increase the sensitivity of detection for pancreatic cancer and enhance the diagnostic value of galectin-3 for pancreatic cancer.

BACKGROUND:Artificial tissue-engineered bone combined with acel ular bone matrix has been shown to be favorable for bone repair. OBJECTIVE:To explore the safety and biocompatibility of the stromal vascular fraction of the adipose tissue combined with the acel ular bone matrix-chitosan scaffold in the repair of rabbit radial defects. METHODS:A total of 38 New Zealand rabbits were selected, 3 rabbits were used to extract stromal vascular fraction of adipose tissue, 3 used to prepare acel ular bone matrix and 32 divided into experimental and control groups. Models of rabbit radial defects were established using Brownlow method. The rabbits in the experimental group were treated with the SVF of adipose tissue combined with the acel ular bone matrix-chitosan scaffold, while those controls received no treatment. General situation, gross observation, X-ray examination, histological observation and Lane-Sandhu scores were performed at 2 and 4 months postoperatively. RESULTS AND CONCLUSION:No infections occurred in both two groups at 2 and 4 months postoperatively, but the activity level and degree of healing in the experimental group were significantly better than those in the control group. In the experimental group, there were high-density shadows at 2 months postoperatively and the X-ray image of the bone defect site was the same as that of the normal one at 4 months, while bone nonunion occurred in the control group. The bone tissues in the experimental group grew significantly better than that in the control group at 2 and 4 months postoperatively, and the Lane-Sandhu histological scores in the experimental group were significantly higher than those in the control group at 2 and 4 months postoperatively (P<0.05). These results indicate that the stromal vascular fraction combined with the acel ular bone matrix-chitosan scaffold exhibits safety and biocompatibility in the repair of rabbit radical defects.

Using the Gram-positive Staphylococcus aureus as the indictor bacterium,fourteen antibacterial strains were initially obtained by the bilayer-media screening method from the raw milk samples,and one isolate was found to exhibit the higher antibacterial activity against the indicator. This isolate was further studied on its individual and cultural morphology features,partial physiological and biochemical reaction activities,G+C content,the sequence features of the 16S rDNA and the species-specific N-acetylmuraminidase gene(acmA) ,consequently,it was identified as the Lactococcus lactis subsp. lactis strain,named as MB191. An evaluation of the antimicrobial spectra of MB191 was subsequently performed,it showed the remarkable activities against not only the tested Gram-positive bacteria,but also several Gram-negative bacteria including Pseudomonas syringae and P. fluorescens,as well as the yeast Debaryomyces hansenii,which was a distinctive feature that was not reported prior to this study.

Objective To investigate the effect of matrix metalloproteinases(MMPs) in ventilator-induced lung injury inflammatory reaction of newborn rabbits.Methods Seventy-five newborn rabbits aged 1-5 days were randomly arranged to 3 groups:control group(n=3),other 72 rabbits designed by 2?2?3 factorial were divided into high concentration oxygen(100%)and low concentration oxygen(45%) groups,and each group was subdivided into 2 groups:High peak inspiratory pressure(PIP)group and low PIP group.All rabbits were done by mechanical ventilation and killed to obtain lung tissue at 1,3,6 hours after trailing respectively.The concentration of MMP-9 and MMP-2 in lung tissue bomogenate were detected by ELISA,at the same time the ratio of wet to dry was detected and pathological section was analyzed.Results 1.The concentration of MMP-2 in high concentration oxygen group,high PIP group and low PIP group increased compared with that in normal group,and there were significant differences.2.The mean concentration of MMP-9 was lower in high concentration oxygen group than that in normal control group,and there was significant difference between 2 groups.The mean concentration of MMP-9 in low concentration oxygen group was higher than that in normal group,and there was no significant difference between 2 groups.There was no significant difference in effect to mean concentration of MMP-9 by different PIP.3.There were positive correlation between MMP-2 and MMP-9,MMP-2 and the ratio of wet to dry in lung.Conclusions Within 6 hours in newborn rabbits by mechanical ventilation,ventilation with high concentration oxygen up-regulate MMP-2,but down-regulated MMP-9.The lungs stretch by mechanical ventilation increase MMP-9,but decrease MMP-2.Mechanical ventilation can affect the synthesis of MMPs,and MMPs plays an important role in ventilator-induced lung injury of newborn rabbits.
