Objective To find methods to isolate and purify plasminogen activator (Pla) from artificial culture of Yersinia pestis. Methods Ultrasonication and urea extracting combined by ammonium sulfate salting-out were tried to extract Pla. High performance liquid chromatography(HPLC) was used to purify Pla. The first step was ion exchange and the second was gel filtration, Preparative electrophoresis was used to purify Pla, too. The enzyme activity of the isolated or purificated Pla was detected. Results Both 50% - 60% saturated ammonium sulfate deposition of supernatant of plague bacilli ultrasonication and 0 - 10% saturated ammonium sulfate deposition of supernatant of plague bacilli powder soaked by urea had three bands(Mr about 31×103, 35×103 and 37×103) and lysis rings were 6.5 and 7.2 mm in diameter respectively when the enzyme activity was detected. Pla purified by HPLC was mainly composed of three bands(Mr about 31×103, 35×103 and 37×103), occupying more than 80% of total protein weight and lysis ring was 5.0 mm in diameter. Pla purified by preparative electrophoresis mainly consisted of three bands(Mr about 31×103, 35×103 and 37×103) with other proteins of low concentration nearby, no lysis ring was detected. Conclusions Pla is collected by the methods of ultrasonication and urea extracting. Priliminary purification of Pla can be achieved by HPLC and preparative electrophoresis.

To explore the relationship between microecological environment and Paeonia lactiflora the effects of growth years of P. lactillora on rhizosphere bacterial communities were studied by PCR-DGGE and the paeoniflorin content determined by HPLC. Results showed that the soil pH increased with growing years of P. lactillora. In the fourth year, soil pH and enzyme activity reached the highest level, while organic matter content was the lowest. The bacterial diversity had a positive correlation with growing years varied from 3.38 to 3.61. Sequencing results demonstrated that Gammaproteobacteria, llphaproteobacteria, Actinobacteria, Acidobacte- ria and Firmicutes were predominant bacteria kinds in the soil of P. lactillora. Gammaproteobacteria was only detected in the bulk soil, while llphaproteobacteria, Acidobacteria G1l, Actinobacteria were only in the rhizosphere soil and the bacterial community among different growing years were similar except few species. HLPC results showed that paeoniflorin content was 3.26%, 3.30%, 3.36%, 3.41% separately from one to four-year-old P. lactiflora with an upward trend. The correlation analysis indicated that the paeoniflorin content had a positive correlation with soil pH and bacterial diversity, conversely, had a negative correlation with organic matter con- tent. During the growth years the rhizosphere bacterial diversity increased without changes of predominant bacteria and the paeoniflorin content increased without significant differences while its production increased significantly, which was different from the plants showing replanting diseases. This is in line with the farming practice choosing 4-year-old P. lactllora, but not the 1-3 year old one. In addition, the accumulation of paeoniflorin is closely related to soil pH, organic matter content and bacteria diversity, confirming that the geoherblism of P. lactiflora is closely related with microbial environment in the soil.

To reveal the effect of rotation cropping and bacterial manure on the growth of Chrysanthemum morifolium and screen the beneficial endophytic, the diversity of endophytic and dominant genera of different treatment groups were analyzed. Four different treatments were continuous cropping, rotation, self-made organic fertilizer and commercially available fertilizer, respectively. Endophytic bacterial diversity and dominant genera in different organs were examined using Terminal Restriction Fragment Length Polymorphism (T-RFLP). The results showed that enzyme Hae III was more appropriate than enzyme Hinfl because the number of TRFs digested by enzyme Hae III was more than that of enzyme Hinfl. In comparison of diversity, the endophytic bacterial communities' diversity index in group of cropping rotation and fertilizer was higher than that of continuous cropping which indicated that the addition of exogenous microorganism in soil could increase the diversity of plant endophyte. 18 dominant species were selected, including 3 kinds of Firmicutes, 4 kinds of Actinomycetes and 11 kinds of Proteobacteria. The results of dominant species comparison showed that the number of dominant species in continuous cropping of Ch. morifolium was significantly less than that of the rotation group. Some dominant bacteria in rotation group and fertilizer group such as Arthrobacter, Streptomyces, Streptomyces, Flavobacterium and Mycobacterium were not found in the continuous cropping of Ch. mortfolium group. Dominant species of fertilizer treatment group was similar with the rotation group, and the continuous cropping group's dominant species was more abundant. It indicates that these bacteria may be able to mitigate hindrance in continuous cropping, especially the Flavobacterium which can decompose the pathogenic fungi is worthy of further attention. Compared with leaves, there are more dominant species in roots and stems. The diversity of edophytic bacterial communities in continuous cropping of Ch. morifolium stays below than that in the rotation of Ch. morifolium, and fertilizer treatment can increase the diversity of continuous cropping so that it could mitigate hindrance in continuous cropping.

To explore the mechanism of soil microbial ecology, the differences of fungal diversities in rhizosphere of different provenances of Fritillaria thunbergii were analyzed. The diversities and compositions of rhizo-fungi of the samples were analyzed by using DGGE and 454 pyrosequencing. DGGE results showed the Shannon index of Ninbo provenance planted in Ninbo was the highest one. And its dominant fungi were Ascomycota, Deuteromycota and Zygomycota. Except the same fungi, every provenance planted in Ninbo had its own special ones. From the 454 pyrosequencing, the fungal diversity in Panan producing was the highest which was similar with DGGE result. Among the ten phylum detected in its rhizosoil, Fungi_incertae_sedis, Ascomycota, Mucoromycotina, Basidiomycota and Chytridiomycota almost amounted to 90% of the whole community. The fungal types and amounts in Panan were more than those in Ninbo indicating the differences between producing areas and the advantage of macro genome sequencing. There were 10 phyla, 29 families, 28 genus and 159 species of fungi in Panan provenance, 6 phyla, 20 families, 19 genus, 136 species in Ninbo provenance, 8 phyla, 37 families, 47 genus, 289 species in Nantong provenance and 7 phyla, 25 families, 24 genus, 102 species in the bulk soil. Some genus such as Dothidea, Capnobotryella and Conidiobolus were only existed in Nantong provenance, while Pyrenochae- ta, Glomus and Pseudonectria were only in Panan provenance, which implied these species could grew because F. thunbergii influenced the existence of fungi. Experiments of provenance and producing area of F. thunbergii showed that the fungal diversity of indigenous provenance was higher than that of exotic provenance and each provenance had unique fungal species in the rhizosphere, which indicated that the diversity and structure was shaped cooperatively by the species and soil type. These fungal species are interacted with the soil-rhizhosphere-microbe microecological system, which in turn influence the growth of F. thunbergii.

Objective:To investigate the acceptance of advance care planning and its influencing factors in heart failure patients.Methods:A total of 208 patients with heart failure were surveyed by general data questionnaires and advance care planning acceptance questionnaires.Results:The total score of advance care planning acceptance of heart failure patients was (44.26 ± 11.73), the score of feeling dimension was (13.67 ± 5.72), the score of attitude dimension was (30.59 ± 6.33). 53.4%(111/208) of patients were willing to accept the talking about advance care planning. Regression analysis results showed that education level, New York Heart Association (NYHA) classification, communication status with medical staff and whether they had received life-sustaining treatment were important factors influencing of the acceptance of advance care planning in patients with heart failure.Conclusion:Patients with heart failure had higher acceptance of advance care planning. In clinical work, it is necessary to strengthen the scientific popularization of advance care planning in patients with low education level, low NYHA grade and no exposure to life-sustaining treatment. And strengthen the daily communication with patients to prepare for the follow-up advance care planning related communication.

This study was aimed to provide a reference for the development, registration, and clinical use of hospital traditional Chinese medicine (TCM) preparations, in order to analyze and assess their safety and risk. It also provided a reference for the technical review and supervision of hospital TCM preparations. Through collecting review materials of hospital TCM preparations from 2012 to 2014 in the Sichuan Food and Drug Administration, 21 preparations developed by clinical experiences were screened out. Analysis was made on their ingredients, preparation process and acute toxicity data. The results showed that 98 kinds of Chinese herbal medicines were contained in 21 preparations. The dosages of herbs were in compliance with theChina Pharmacopoeia2010 Edition. Preparation processes of 16 preparations were made by water extraction, grinding and other traditional techniques. The preparation processes of the remaining 5 preparations were involved with alcohol extraction or alcohol precipitation. Acute toxicity test data were obtained with experimental data in mice. Clinical usages of preparation were much lower than MTD or LD50. It was concluded that these hospital TCM preparations developed by clinical experiences were with high safety.

BackgroundPocket hematoma is one of the major complications associated with cardiovascular implantable electronic devices (CIEDs) implantation. The aim of this study is to evaluate the impact of body mass index (BMI) on the occurrence of pocket hematoma after CIEDs implantation.MethodsThe study is a retrospective review of 972 patients receiving CIEDs implantation between 2008 and 2012 in a tertiary hospital.ResultsTwenty two patients (2.2%) developed severe pocket hematoma requiring re-intervention. The hematoma rate (4.6%,n = 15) of patients with a BMI of < 23 kg/m2 was significantly higher compared with that of patients with a BMI of≥23 kg/m2 (1.1%, n = 7,P< 0.001). In multivariate regression analysis, a BMI < 23.0 kg/m2 may be associated with the development of severe pocket hema-toma. An increase of 1.0 kg/m2 in BMI was associated with lower incidence of hematoma formation (OR: 0.84; 95% CI: 0.74-0.95;P = 0.006).ConclusionBMI < 23 kg/m2 was associated with a higher incidence of pocket hematoma, requiring re-intervention. The data sup-port that great care must be taken when patients were with a lower BMI received CIEDs implantation.
