It was found that angle and time, especially angle factor obviously affected the testing results.

Phytoremediation effectiveness and remediation costs are driving factors of this project. Full utilization of plant resources after their being used for phytoremediation is an unsolved problem. GC/MS technique was used to investigate the volatiles of the flowers from Elsholtzia argyi (PFE1: Purple Flower Elsholtzia) and their variation (WFE: White Flower Elsholtzia), naturally growing in Pb/Zn mined area, and Elsholtzia argyi (PFE2: Purple Flower Elsholtzia), naturally growing in Jiuxi uncontaminated agriculture soil. Seventeen compounds constituting 86.88% of total essential oils were identified in PFE1, with 2,6-octadienoic acid,3,7-dimethyl-methyl ester being the main constituent (63.30%). Sixteen compounds accounting for 95.32% of total essential oils were identified in WFE, with caryophyllene being the main component (55.02%). Compared to PFE1, PFE2 contains lower level of 2,6-octadienoic acid,3,7-dimethyl-methyl ester (31.76%), which is the main constituent in the total essential oils of PFE2. Caryophyllene is the main ingredient of flavor. Elsholtzia ketone was identified in all the three Elsholtzia plants. It can be concluded that the selected Elsholtzia argyi plants can be exploited on their versatile uses as fragrances and antiseptics due to the perfume ingredient and antibacterial components existing in their essential oils.

normal males were tested by BIODEX isokinetic test and rehabilitation system and its closed chain attachment.The results show that Peak Torque,Peak Torque/Body Weight,Time to PT,Total Work,Total Work/Body Weight and Average Power were higher when extention than flexion.There were no significant influence on D1/D2 ratio.And the results with closed chain are the same with non closed chain test.

Objective Vessel injury provokes the release of angiotensin II that influences the proliferation and migration of vascular smooth muscle cells (VSMCs). T lymphocytes produced, interleukin 10 is of immunoregulatory function. The purpose of this study is to determine the effects of recombinant human interleukin 10 (rhIL 10) on the proliferation of isolated rat vascular smooth muscle cell and the activity of p44/p42 mitogen activated protein kinase (MAPK) promoted by angiotensin II. Methods Rat aortic VSMCs were cultured and treated with rhIL 10 or angiotensin II, and then co treated with rhIL 10 and angiotensin II. The proliferation was quantified by colormetric assay. The p44/p42 MAPK activity was evaluated by the immunobloting technique using anti p44/p42 phospho MAPK antibody. Results Compared with control group, angiotensin II stimulated significantly VSMCs proliferation(1 311?0 201 vs 0 781?0 236, P 0 05), but significantly inhibited VSMCs proliferation induced by angiotensin II at a dose of 1,10,100 ng/ml (0 984?0 172 , 0 932?0 134 , 0 784?0 097 vs 1 311?0 201, P

A strain of Cellulosimicrobium cellulans Ha8 was studied on its morphological, biological characteristics and its utilization of several kinds of benzoic compounds, the results showed this strain was Gram-positive, the long rod-shaped cells were changed into short rod-shape gradually. pH value from pH 6.0 to pH 9.0 and the temperature from 20 ℃ to 40 ℃ were good for its growth. It could not only hydrolyze protein and starch, use cellulose and pectin, decomposite chitin, liquify gelatin and fix nitrogen, but also use phenol, xylene, benzoic, cinnamic acids and diphenlamine as the sole carbon resource for its growth. It could tolerate 0 mmol/L~30 mmol/L, 0 mmol/L~8 mmol/L, 0 mmol/L~30 mmol/L, 0 mmol/L~15 mmol/L and 0 mmol/L ~ 40 mmol/L of benzoic acids, phenol, xylene, cinnamic acids and diphenlamine seperately, but could not use 2,4-dinitrophenol, o-Nitrophenol, 2-Methoxyphenol, aminobenzenesulfonic acid, catechol and o-Phenanthroline as its sole carbon resource.

Objective:To explore the action of the second signal system in the activatied and proliferating T cells and the induction of apoptosis of the hepatoma cells.Methods:The T cells were costimulated by anti CD28 and anti CD80(B7.1)McAb and acted on the hepatoma cells(BEL 7402),then testing the concentration of cAMP?cGMP and Ca 2+ in the T cells and the apoptosis of the hepatoma cells.Results:The concentration of cAMP was increased temporarily at first,then decreased rapidly,and increased 1 2 times again when acted on the hepatoma cells.The concentration of cGMP was increased 6 8 times fast and the concentration of Ca 2+ obviously increased 2 3 times too.The peak of them was at the fourth day and positive related to apoptosis of the hepatoma cells.Conclusion:The level of the second signal system of cAMP?cGMP and Ca 2+ were significant correlated with the T cells activated and porliferating and the cytotoxic effect.

Objective To investigate the expression of interleukin-6(IL-6),high mobility group protein B1 (HMGB1)and Survivin in patients with gastrointestinal stromal tumors (GISTs)and the relationship between them.Methods 43 patients with GISTs and 30 healthy controls from Jan.2009 to Dec.2012 in Nanchong Central Hospital was enrolled.Expressions of IL-6,HMGB1 and Survivin in serum were assessed with enzyme linked immunosorbent assay(ELISA) and the correlation among IL-6,HMGB1 and Survivin was analyzed.Results The serum levels of IL-6,HMGB1 and Survivin in patients with GISTs((0.61 ±0.05)ng/ml,(3.54 ±0.74) ng/ml,(0.15 ± 0.04)ng/ml,respectively)were higher those that in the healthy controls((0.32 ± 0.03)ng/ml,(1.81 ± 0.06)ng/ml,(0.07 ±0.02)ng/ml,respectively).Among the 43 GISTs,the expressions of IL-6,HMGB1 and Survivin in benign,potentially malignant and malignant group increased gradually.The expressions of IL-6 in each group were (0.55 ± 0.02) ng/ml,(0.59 ± 0.02) ng/ml,(0.64 ± 0.03) ng/ml,respectively,The expressions of HMGB1 in each group were (2.82 ± 0.55) ng/ml,(3.46 ± 0.16) ng/ml,(4.00 ± 0.61) ng/ml,respectively.The expressions of Survivin in each group were (0.10 ± 0.01) ng/ml,(0.15 ± 0.02) ng/ml,(0.18 ± 0.03) ng/ml,respectively.Expressions of IL-6 and HMGB1,IL-6 and Survivin,and HMGB1 and Survivin were positively correlated(r =0.699,P ＜0.05;r =0.774,P ＜0.05;r =0.595,P ＜0.05,respectively).Conclusion The high expression of IL-6,HMGB1 and Survivin may together contribute to the malignancy,invasion and metastasis of GIST.Detection of these three markers may be useful in judging the malignancy degree and predicting the prognosis of GIST.

Objective To study the long-term neurodevelopment in term neonates with hyperbilirubinemia and explore the predictive value of cerebrospinal fluid neuron specific enolase (CSF-NSE) on long-term neurodevelopment outcome.Methods A mental and psychomotor scale for 0-4 years old was performed to evaluate the intelligence development of 39 neonates with hyperbilirubinemia and 39 randomly selected healthy controls when they were at 3 to 24 months old. The former were tested for the level of CSF-NSE in jaundice climax.Results There was significant difference between 2 groups in total development quotient (DQ) tested at 3 month and 24 month old (P=0, 0.047). It was shown that the DQ scores for fine activity and social behavior were significantly lower in the study group than those in the control group (Pa=0). Furthermore, within the hyperbilirubinemia group, CSF-NSE was significantly associated with DQ of 3 month and 24 month old, while there was not association with TSB. The correlation coefficients were -0.46(P=0.04) and -0.32(P=0.047),respectively.Conclusions Hyperbilirubinemia may influence long-term neurodevelopment of term infants and CSF-NSE can predict this outcome.
