Isolation and identification of endophytic fungi from different swollen root of Rehmannia glutinosa / 中国中药杂志

The swollen root of Rehmannia glutinosa is used as one kind of important Chinese traditional medicine. The root of R. glutinosa usually swelled in rotational cropping but not in continuous cropping. The rhizosphere microorganisms of R. glutinosa under different farming condition were thought related to that. In this study, the endophytic fungi in the root of R. glutinosa growing in various soil conditions were isolated for the study of the relationship between the microorganisms and the root enlargement of their host plants. The dominant endophytes, Verticillium spp., Fusarium oxysporum, F. redolens and Ceratobasidium spp. were identified by morphological observation and 18S rDNA and ITS sequence analysis. The preliminary investigation showed that the excessive growth of Verticillium and Fusarium genus fungi is unfavorable for the R. glutinosa root swelling, but Ceratobasidium fungi has no effects on the root enlargement.

Study on Sterilization and Disinfection of Sickbed / 医疗卫生装备

Effective strategies to sterilize and disinfect the surface of sickbed should be adopted before the sickbed is moved into or out of an operation room.Ozone produced by Nano technology is used as disinfector.The experiments shows that the killing logarithm value to kill nature bacteria is between 0.54 and0.85 in short time.The effect of sterilization and disinfection for the surface of sickbed is satisfying without secondary pollution,so the new method can be used to sterilize and disinfect sickbed.

Super-early Minimal Invasive Evacuation of Hematoma via Keyhole for Treating Hypertensive Basal Ganglionic Hemorrhage / 中国医师杂志

Objective To estimate the efficacy of super-early minimal invasive evacuation of hematoma via keyhole for treating hypertensive basal ganglionic hemorrhage. Methods 36 patients with hypertensive basal ganglionic hemorrhage(9 cases in grade Ⅱ, 17 in grade Ⅲ and 10 in grade Ⅳ) were treated by minimal invasive evacuation of hematoma via keyhole at super-early stage, and their efficacy was statistically compared with 35 patients with hypertensive cerebral hemorrhage underwent conservative therapy or lateral ventriculopuncture. Results In the 36 patients underwent minimal invasive evacuation of hematoma via keyhole, 22 cases had a good prognosis(61.1%), 9 had a poor prognosis(25.0%), and 5 died(13.9%). Among the 35 patients underwent conservative therapy or lateral ventriculopuncture, 5 cases had a good prognosis(14.3%), 22 had a poor prognosis(62.9%), and 8 died(22.9%). There was a significant difference in good and poor prognostic rate between the two groups(P
