Background and purpose:High mobility group 1 (HMGB1), frequently found to be over-expressed in many human tumors, plays an important role in tumor progress and metastasis. This study aimed to investigate the mechanism of HMGB1 promoting A549 cell metastasis.Methods:A549 cells were untreated or treated with HMGB1 (200 ng/mL) in absence or presence of NF-κB inhibitors 6-amino-4-quinazoline (QNZ, 40 nmol/L) or Bortezomib (Bort, 20 nmol/L). Scratch assay and Transwell assay were performed to evaluate A549 cells migration and invasion ability. The activity of NF-κB was examined by luciferase reporter assay. NF-κBp65 and αvβ3 expressions were detected by Real-time RT-PCR or Western blot.Results:HMGB1 increased A549 cells migration and invasion ability. HMGB1 enhanced NF-κB protein level and NF-κB activity in A549 cells. Real-time RT-PCR and Western blot showed that HMGB1 up-regulated αvβ3 expression in A549 cells. NF-κB inhibitors QNZ or Bort reserved the promot-ing effects of HMGB1 on A549 cells migration and invasion, NF-κB expression and activity as well as αvβ3 expression. Conclusion:HMGB1 promotes A549 cell migration and invasion through activating NF-κB and up-regulating αvβ3.

Since the fecal bacteria transplantation (FMT) had been exist for a long time, it attracted more attention in recent years because this therapy could adjust the bacteria disturbance rapidly in clinical settings. Recent studies demonstrated that fecal microbiota transplantation (FMT) has great clinical value in the treatment of Clostridium difficile infection, inflammatory bowel disease, Intractable functional constipation and other diseases. But the FMT is not as perfect as we expect, so we did this article to review the history and terminology of FMT, and summarized the progress in nursing methods of FMT.

Objective To study the effect of different doses of monocrotaline in combination with isopropylarterenol on the hemodynamic resonse, heart index and right heart hypertrophy index in rats.Methods Sixty-four healthy adult SD rats, male:female=1∶1, body weight 200-250 g, were randomly divided into blank control group (n=16) and three model groups (n=16 in each group).The high dose model group (n=16) received i.p.injection of monocrotaline 80 mg/kg once and epinephrine 10 mg/kg once daily for one week.The moderate dose group received i.p. injection of monocrotaline 55 mg/kg once and epinephrine 8 mg/kg once daily for one week.The low dose group received i. p.injection of monocrotaline 30 mg/kg once and epinephrine 3 mg/kg once daily for one week.The rats were fed for 6 weeks, and then pulmonary artery pressure and right ventricular pressure were tested and heart index and right ventricular hypertrophy index were determined.Results Compared with the control group, the mean pulmonary artery pressure and right ventricular systolic blood pressure in the low dose monocrotaline group were not significantly changed, but significantly changed in the moderate dose monocrotaline group ( P<0.05) .The heart index and right ventricular hypertrophy index in the low dose monocrotaline group were not significantly changed, but in the moderate dose monocrotaline group, the heart index was significantly reduced ( P<0.01 ) and the right ventricular hypertrophy index was significantly increased ( P<0.05 ) .Conclusions The use of a single injection of 55 mg/kg monocrotaline in combination with continuous injection of 8 mg/kg isopropylarterenol once daily for one week can ensure the survival rate of rats, and the successful formation of pulmonary artery hypertension, leading to heart weakness.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

A novel method for the simultaneous quantification of seven metabolites of polycyclic aromatic hydrocarbon in human urine was developed using online solid phase extraction-HPLC with double ternary liquid chromatography system combined with fluorescence detector. The target compounds were online concentrated on the Turboflow Cyclone solid phase extraction column at first, then transferred by the six-way valve to the Hypersil Green PAH column for separation with acetonitrile and water as mobile phase at a flow rate of 1. 0 mL/min and at 35 ℃. A single sample analysis cycle took only 20 min. Under the optimized chromatographic conditions, the method showed good linear relationship ( r≥0. 999 ) in the range of 5-2000 ng/L or 50-20000 ng/L. The LODs were 0. 5-15 ng/L, and the recoveries were 80. 7%-110. 7%. The proposed method was successfully applied in the detection of metabolites of polycyclic aromatic hydrocarbons in urine from several smokers and non-smokers. The concentrations of 2-hydroxynaphthalene, 1-hydroxynaphthalene, 2-hydroxyfluorene, 2-hydroxyphenanthrene, 4-hydroxyphenanthrene and 6-hydroxychrysene in the smokers urine were much higher than that in non-smokers.
