Objective To assess the effects of protease 3(PR3)and protease-activated receptor (PAR)-2-activator on the maturation and functions of peripheral blood dendritic cell(DC)-like monocytes.Methods Density gradient centrifugation was used to isolate peripheral blood mononuclear cells(PBMC)from Wegener's granulomatosis(WG)patients and healthy controls(HC).PBMC were stimulated by LPS,human PR3,trypsin,PAR-2-agonist peptide (PAR-2-AP),LPS+PR3 or LPS+trypsin for 24 h.Flow cytometry was used to analyze the expression of PAR-2,CD80,CD83,HLA-DR on stimulated DC-like monocytes-CD14+CD16high monocytes.ELISA kit was used to test the concentration of IL-6 in the culture supernants.Mann-Whitney non-parameteric test was used fur statistical analysis.Resuits No effect of PR3,trypsin and PAR-2-AP on the expression of PAR-2,CD80,CD83,HLA-DR of DC-like monoeytes was found.LPS could significantly induce PAR-2 expression in HC[from(5.8±1.5)%to(24.5±4.5)%,P=0.002]and the expression of CD80,CD83,HLA-DR in HC and WG;PR3,trypsin,PAR-2-AP and LPS could all stimulate the secretion of IL-6.Conclusion PR3 and PAR-2 pathway-activators can not promote PAR-2expression and maturation of DC-tike monocytes,but they can induce the secretion of IL-6.

Objective The aim of this study was to assess the status of protease-activated receptor-2(PAR-2) expression on the peripheral blood immune cells including dendritic cells(DC) of Wegener's granulo matosis(WG) patients.Methods Flow cytometry was used to analyze the expression of PAR-2 protein on peripheral blood immune cells,DC and DC-like monocytes of healthy controls (HC),inactive,active and different medicine-treated WG patients.Two-tail Mann Whitney non-parametric test was used for statistical analysis.Results There was no difference of PAR-2 expression on PMN,monocytes,lymphocytes and DC between WG patients and HC.However,PAR-2 expression on CD14+CD16+ (t=3.823,P=0.004) and CD64+CD16+ (t=2.652,P=0.024) DC-like monocytes was much higher in WG patients compared with HC.In active WG,expression of PAR-2 was up-regulated on the cell surface of PMN (t=2.690,P=0.013 ),monocytes (t=1.688,P=0.047),lymphocytes(t=1.742,P=0.038),BDCA3+DC(t=2.582,P=0.016),CD11c+DC(t=1.828,P=0.044),CD14+CD16+ (t=3.419,P=0.002)and CD64+CD16+ (t=3.494,P=0.005) DC-like monocytes when compared with inactive WG.PAR-2 expression on these cells was similar between cyclophosphamide (Cyc) and Methotrexate (MTX) treated WG patients.Conclusion PAR-2 expression on immune cells,DC and DC-like monocytes correlates with WG occurrence and development.There is no difference in the effects on PAR-2 expression between various medications.

The dialysis for three species of poplar stems apoplast was obtained by microdialysis method, and then the concentration of Na+, K+, Ca2+ in the dialysis sample was directly measured by graphite furnace atomic absorption spectrometry ( GF-AAS) . The flow rate of perfusate was 1μL/min and the cut-off molecular weight of probe was 30 kDa. The real-time and non-destructive test technique established for the detection of ion concentration could be applied in research of poplar biochemical physiology. The recovery of the proposed method was 95. 8%-103. 1%. The contents of sodium ion in Populus wutunensis, Populus simonii and Salix matsudana were 1034-1156 μg/L, 1493-1611 μg/L and 1586-1703 μg/L; potassium ion were 1012-1237 μg/L, 941-964 μg/L and 1095-1201 μg/L; calcium ion were 4976-5237 μg/L, 4786-5042 μg/L and 5893-6142 μg/L. The method could provide reliable data for the study of ion concentration changes of plant response to adapt to all kinds of external environment.

Rare sugars were defined as monosaccharides and their derivatives that rarely exist in nature. They played an important role in food, health, medicine and etc A strategy for bioproduction of rare sugars, namely Izumoring, was described. By the Izumoring method, all monosaccharides and polyols could be linked, using enzymatic reaction with D-tagatose 3-epimerase, aldose isomerases and polyol dehydrogenases. Izumoring for hexoses, pentoses and tetroses were designed respectively. According to this strategy, the bioproduction routes of various rare sugars, using microbial and enzymatic reactions, could be obtained. In addition, the future research tendency of biotransformation of rare sugars was put forward.

An extracellar fibrinolytic strain was isolated from fermented shrimp paste. In addition to general physiological and biochemical properties, the strain was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain had high similarity with AY601723 and AB195282, suggesting that the strain is a subspecies of Bacillus sp. It was named as Bacillus sp. nov. SK006 by CCTCC. The medium composition and fermentation conditions for fibrinolytic enzyme production were also optimized in the research.

0.05).The ultramicrostructure of cells detected by electron microscope showed that GJIC function in transfected group was higher than that in the other two groups.While in migration assay,the numbers of cells in lower chamber passing through the membrane in transfected group,blank control group and negative control group were 112?23,306?49 and 322?91, respectively;with significant differences among 3 groups(P

Objective To evaluate the safety and efficacy of endoscopic treatment in patients with primary hepatic carcinoma and gastroesophageal variceal hemorrhage. Methods Thirty cases of hepatic carcinoma with gastroesophageal variceal hemorrhage diagnosed with gastroscopy between January 2008 and June 2015 in Chinese PLA General Hospital and Hainan branch were included. Patients′ clinical data, complications and therapeutic effects of endoscopy were retrospectively analyzed. Results All patients underwent endoscopy successfully. No recurrent bleeding was found in any case after treatment. Eight cases of varicosis nearly disappeared. Six?month follow?up showed three cases of gastrointestinal bleeding, one case of death of bleeding, and no recurrence hemorrhage in 27 others. Conclusion Endoscopic treatment could safely and effectively control the primary liver cancer combined with gastroesophageal variceal hemorrhage, hence may provide opportunity for further treatment of liver cancer.

Objective To investigate the value of intraoperative neuromonitoring(IONM) for preventing recurrent laryngeal nerve(RLN) injury in thyroid surgery.Methods 1087 consecutive patients undergoing thyroid surgery at Wuhan Central Hospital from Oct 2010 to Dec 2012 were evaluated.277 cases(the study group) underwent thyroidectomy with RLN identification by naked eye plus IONM.810 cases(the control group)underwent thyroidectomy with RLN identification by naked eye only.Results In the control group,733 RLNs (90.49％,733/810)were successfully identified and 77 RLNs were failed to be identified.In the study group,all the 277 RLNs(100％,277/277)were successfully identified.28 cases had postoperative temporal RLN injury,among whom 26 cases were in the control group and 2 cases were in the study group.18 cases in the control group and 2 cases in the study group recovered in 2 weeks after surgery.The rest recovered in 2 months after surgery.RLN injury rate was significantly lower in the study group than in the control group.There was no significant difference in RLN injury for low-risk surgical patients between the 2 groups; however,the study group had advantages in RLN injury than the control group for high-risk patients.Conclusions IONM in thyroid surgery can improve the recognition rate of RLN during thyroidectomy.IONM can significantly reduce the incidence of RLN injury,especially in high-risk surgery.
