Biochar could be got from crop straw which contain rich carbon under oxygen free or oxygen limited conditions at low temperature. The application of biochar into soil is beneficial to ease the pressure of handling straw, reduce pollution, reduce greenhouse gas emissions and improve soil quality. This study was carried out in a cornfield containing meadow brown soil at the lower reaches of Liao River which was treated with different amounts of biochar (0, 360, 1 800, 3 600 kg·ha-1) and fertilizer. We investigated the contents of soil available phosphorus (AP), organic P (OP) and total P (TP). We also investigated the enzyme activities of soil acid phosphatase (AcP), alkaline phosphatase (AlP) and phosphodiesterase (PD) via a fluorescence spectroscopy method by using a fluorescent conjugated polymer as the substrate. Soil AP contents increased drastically with the increasing application of biochar, whereas the OP and TP contents exhibited little change. The increase in AP contents was ascribed to the introduction of P into the soil via biochar. Soil AlP and PD activities increased with increasing biochar application. Soil AcP activity increased significantly after the application of the appropriate amount of biochar (1 800 kg·ha-1), whereas it was inhibited by the application of high levels of biochar (3 600 kg·ha-1), perhaps due to the intrinsic alkalinity of biochar. The effect of Biochar inputs on soil phosphorus element and phosphatase activity is the comprehensive embodiment of the soil physical properties, chemical properties, and microbial community structure and metabolic capacity. We should further study such item. The fluorescent microplate method used in this study has many advantages, such as accuracy, rapidness and simple to perform.
ABSTRACT
The utilization of organic phosphorus (P) has directly or indirectly improved after exogenous phytase was added to soil. However, the mechanism by which exogenous phytase affected the soil phosphatases (phosphomonoesterase and phosphodiesterase) activities was not clear. The present work was aimed to study red soil, brown soil and cinnamon soil phosphomonoesterase (acid and alkaline) (AcP and AlP) and phosphodiesterase (PD) activities responding to the addition of exogenous phytase (1 g phytase/50 g air dry soil sample) based on the measurements performed via a fluorescence detection method combined with 96 microplates using a TECAN Infinite 200 Multi-Mode Microplate Reader. The results indicated that the acid phosphomonoesterase activity was significantly enhanced in red soil (p≤0. 01), while it was significantly reduced in cinnamon soil; alkaline phosphomonoesterase activity was significantly enhanced in cinnamon soil (p≤ 0. 01), while it was significantly reduced in red soil; phosphodiesterase activity was increased in three soils but it was significantly increased in brown soil (p≤0. 01) after the addition of exogenous phytase. The activities still remained strong after eight days in different soils, which indicated that exogenous phytase addition could be enhance soil phosphatases activities effectively. This effect was not only related to soil properties, such as pH and phosphorus forms, but might also be related to the excreted enzyme amount of the stimulating microorganism. Using fluorescence spectroscopy to study exogenous phytase addition influence on soil phosphatase activities was the first time at home and abroad. Compared with the conventional spectrophotometric method, the fluorescence microplate method is an accurate, fast and simple to use method to determine the relationships among the soil phosphatases activities.

CALLG2008 Protocol is sequential chemotherapy for adult acute lymphoblastic leukemia (ALL) established by Collaborative Group of adults acute lymphoblastic leukemia. It is emphasized that comprehensive treatment of adult ALL according to risk stratification is rather important. This study was purposed to evaluate the therapeutic efficacy of CALLG2008 for adult ALL. The clinical data of adult ALL patients of ≥ 14 years old diagnosed and treated by CALLG2008 Protocol were collected from May 1, 2009 to December 31, 2011 in Fujian Medical University Union Hospital, and the efficacy was analyzed. The results showed that 31 out of 33 cases of ALL achieved CR, the CR rate was up to 93.9%, the PR rate was 3.1%, and the total response rate was 97%. There were no uncontrolled severe toxicities, and no early deaths were observed. The overall survival (OS) at 1 year was only 66.7%,the relapse rate was 43.8% and the 1-year mortality was 33.3 %. This may be related with no-enough compliance, no-enough economical support and short follow-up time of the patients. The risk factor analysis showed that WBC level in newly diagnosed patients may influence the OS and relapse-free survival (RFS) of ALL. It is concluded that CALLG2008 protocol applied to adult ALL has a high remission quality and low mortality rate during the induction. The disease free survival (DFS) needs to be observed longer. It is essential to carry out MRD monitoring to determine the early recurrence and improving the long-term efficacy.

OBJECTIVE: To compare the clinical efficacy of the infiltration anesthesia with primacaine and the nerve blocking anesthesia with lidocaine for microport extraction of impacted lower third molar. METHODS; 104 chosen patients had both sides of impacted lower third molars extracted in this study. Patients were given local anesthesia with either primacaine or lidocaine randomly at each side, and then underwent microport extraction. Clinical factors including effective proportion (EP), effecting time point (ETP), visual analogue scale of pain (VASp), alteration of systolic pressures (ASP) and analgesia duration (AD) were evaluated statistically by means of paired t-test. RESULTS: The EP of experimental group was higher than the control group (P = 0.024). The ETP of soft tissue and alveoli-dental pulp was (1.04 +/- 0.21), (2.44 +/- 2.60) min in the experimental group, and much earlier than that of the control group (P = 0.002, P = 0.032). The VASp and ASP of experimental group were lower than the control group (P = 0.041, P = 0.018). AD was (103.6 +/- 35.5) min, and higher than the control group (P = 0.04). CONCLUSION: The infiltration anesthesia with primacaine has been proven to be a easier, reliable and quick-acting method. We suggest it an alternative method replacing the 2% lidocaine blocking during microport extraction of impacted lower third molar.
