The effect on the growth and phenol degradation of the thermophilic strain BF80 by seventeen different metal ions were studied. The results showed that the metal ions certainly affected the growth and phenol degradation of the strain BF80. At the concentration of 0.01%,contrasting to the comparison,the growth and phenol degradation of the strain BF80 were restrained intensively by the metal ions of Cu2+,Zn2+,Co2+,Ba2+,Hg2+,Ni2+,Ag+,Al3+. The metal ions of Cr2+ restrained the phenol degradation of BF80 strongly while Cr2+ restrained the growth of BF80 faintly. The metal ions of Sn2+,Fe2+,Fe3+,Pn2+ restrained the growth and phenol degradation of the strain BF80 at a certain concentration,and the effect of inhibition in-creased with the increase of the concentrations of the metal ions. At the low concentration of Mn2+ or Mo2+,the growth and phenol degradation of the strain BF80 were increased,but if the concentration beyond the 0.1%,the growth and phenol degradation of the strain BF80 were inhibited. At the different concentration of Ca2+ or Mg2+,the growth of the strain BF80 were increased and the phenol degradation were accelerated,but the max rate of phenol degradation by BF80 was not influenced obviously. When the medium was added themixture of metal ions of Mo2+ and Mn2+,the strain BF80 grew better,but the rate of the phenol degradation was lower than that of single Mo2+ and Mn2+.

Objective To study the clinical effect of SCOFIX on thoracolumbar fracture.Methods The clinical data of twenty-five cases with thoracolumbar fracture treated with SCOFIX system were retrospectively anal- ysed.Results With six to twenty-two months follow-up,anterior height of compressed vertebral bodies was restored from 46.8 %(12%～60%)preoperatively to 92%(90%～100%)postoperatively,and that of posterior height was from 77.5%(26%～86%)to 96.7%(90%～100%).Cobb's angle was from 15.7?(12?～26?)preoperatively to 1.4?(0?～6?)postoperatively.Conclusion SCOFIX system was simple structured,easily used and strongly fixed, and it was a good system in spinal internal fixation and for deeply reseach.

0.05).The required dose of LT4 during the second and third trimester was respectively,remarkably increased compared to pre-gestational period (P

Objective To evaluate the effect of tissue factor (TF), tissue factor pathway inhibitor-1,2 (TFPI-1,2) on cancer metastases and thrombosis complicated with cancer. Methods Blood samples from 292 cancer patients were collected and were divided into different teams according to cancer types,complicated with or without thrombosis; TF, TFPI-1, TFPI-2, plasma concentrations were measured by ELISA;Tissue expression of TF, TFPI-1, TFPI-2 were observed by immunohistochemical method. Results Plasma concentrations of TF and TFPI-1 in all kinds of cancers were higher than the control and lung cancer was the highest; TFPI-2 plasma concentrations had no statistics differences among all these teams. Tissue expression of TF of all kinds of cancer were higher than the adjacent tissues, lung cancer was higher than the other types of cancer. There were no statistics differences for TFPI-1 and TFPI-2. Both TF and TFPI-1 plasma concentrations of cancer with-or without-thrombosis were higher than control. TF was even higher in cancer with thrombosis team, TFPI-1 had no statistic difference between these two teams. TFPI-2 concentrations had no differences among all these teams. Conclusion Many kinds of tumor have higher expression of TF, it is expressed with different intensity according to different types of cancer. TFPI-1 has no clear effect in cancer growing and metastases. Unbalance of TF and TFPI-1 in plasma may relate to high coagulation state of cancer and may accelerate the thrombosis formation in cancer.

The paper described the necessity of the doctor-patient information exchange platform,and defects found in existing platforms. Such a platform is conducive to higher hospital informationization, better patient satisfaction, and better social and economic benefits of the hospital.The hospital may improve its quality of care and patient satisfaction by means of the platform

Identification and validation of a new target is one of the most important steps for new antituberculosis (TB) drug discovery. Researches have shown that Mycobacterium tuberculosis (Mtb) encodes 20 CYP450 enzymes which play important roles in the synthesis and metabolism of lipid, cholesterol utilization, and the electron transport of respiratory chain in Mtb. With the critical roles within the organism as well as the protein structures of six Mtb CYP450 enzymes being clarified, some of them have been highlighted as potential anti-tuberculosis targets. In this paper, the phylogenetic analysis, the structural features, and the enzymatic functions of Mtb CYPs, as well as the mechanism of interactions with selective inhibitors such as azole antifungal agents for the CYPs have been reviewed and summarized. The druggability of the CYPs has also been analyzed for their further utility as targets in high throughput screening and rational design of more selective inhibitors.

The assisted reproductive techniques in China have witnessed rapid development in the past two decades.However,it also brings up issues of ethics and laws,especially the urgent regulation and reinforcement of the procedure of informed consent.This article begins with an explanation of the procedure of informed consent.Then it discusses the decision of the content,major and difficult points of informed consent in assisted reproductive technology services based on the practice in this field.Finally,it discusses the challenges to informed consent.To well enforce an informed consent process,we should first ensure the contents are reasonable and just;second,clinicians should have a scientific understanding of the importance of informed consent and establish normative procedure of informed consent;third,we must work according to relative ethic demands.Last but not least,respecting patients is the key to the principle of ethics.

Objective The objective of this study was to compare the differences between Volumetric Modulated Arc Radiotherapy(VMAT)and Fixed Field dynamic Intensity Modulated Radiotherapy(dIMRT)in dose distribution of target and organ at risk and treatment time,and to provide basis for clinical treatment.Methods Ten patients with postoperative of cervical carcinoma were selected,VMAT and seven fields dIMRT plans were designed for each patient in Monaco 5.11 planning system.We compared the differences of dose distribution of target and organ at risk,monitor units and treatment time between VMAT and 7dIMRT.Results The average dose of target for VMAT plan(46.86 Gy)was higher than that of 7dIMRT plan(46.68 Gy)(P<0.05).The percentage of the V10 and V20 of rectum and the V30 of small intestine in VMAT plan was 0.63%,3.34% and 4.14% higher than that in 7dIMRT plan,respectively(P<0.05).The conformal index(CI),homogeneity index(HI)of PTV and the other exposure dose of organ at risk for both plans were no significant differences.The average monitor units and treatment time of VMAT plan were 13.4% and 50.6% than that of 7dIMRT plan,respectively(P<0.05).Conclusion The dose distribution of VMAT plan is better or equal to that of 7dIMRT plan,but the monitor units and treatment time of VMAT plan is decreased significantly,we suggest that VMAT plan should be used for postoperative of cervical carcinoma in clinical.

AIM: To investigate the processing and HPLC fingerprint of Radix Scutellariae processed with wine,and to set up appropriate quanlity control standard. METHODS: chromatographic condition of HPLC-UV fingerprint consisted of Hypersil C_18 column(200 mm?5.0 mm,5 ?m),mixture of methanol,0.4% phosphoric acid and acetonitrile as a mobile phase in a gradient mode.Flow rate was 1.0 mL/min and detection wavelength was set at 277 nm. RESULTS: There were no evident differences among fingerprints of Radix Scutellariae that was normatively processed from the production areas. CONCLUSION: The process is feasible,and can be used to provide a basis for quanlity control of Radix Scutellariae.
