| 1 | C:N:P stoichiometry and nutrient limitation of the soil microbial biomass in a grazed grassland site under experimental P limitation or exces显示文摘Introduction:The availability of essential nutrients,such as nitrogen(N)and phosphorus(P),can feedback on soil carbon(C)and the soil microbial biomass.Natural cycles can be supplemented by agricultural fertiliser addition,and we determined whether the stoichiometry and nutrient limitation of the microbial biomass could be affected by an unbalanced nutrient supply.Methods:Samples were taken from a long-term trial(in effect since 1968)with annual applications of 0,15 and 30 kg P ha^(−1) with constant N and potassium.Soil and microbial biomass CNP contents were measured and nutrient limitation assessed by substrate-induced respiration.Linear regression and discriminant analyses were used to identify the variables explaining nutrient limitation.Results:Soil and biomass CNP increased with increasing P fertiliser,and there was a significant,positive,correlation between microbial biomass P and biomass C,apart from at the highest level of P fertilisation when the microbial biomass was over-saturated with P.The molar ratios of C:N:P in the microbial biomass remained constant(homeostatic)despite large changes in the soil nutrient ratios.Microbial growth was generally limited by C and N,except in soil with no added P when C and P were the main limiting nutrients.C,N and P,however,did not explain all the growth limitation on the soils with no added P.Conclusions:Increased soil C and N were probably due to increased net primary production.Our results confirm that C:N:P ratios within the microbial biomass were constrained(i.e.homeostatic)under near optimum soil conditions.Soils with no added P were characterised by strong microbial P limitation and soils under high P by over-saturation of microorganisms with P.Relative changes in biomass C:P can be indicative of nutrient limitation within a site. | Bryan S Griffiths Annette Spilles Michael Bonkowski | 2012 | Ecological Processes2012，1，1： | 23 |
| 2 | 来华医学留学生儿科临床技能学教学模式的改革与发展显示文摘近年来,我国医学教育取得令人瞩目的成绩,越来越多的外国学生选择至我国医学院校接受本科及研究生医学教育。在此过程中,临床技能是医学生由医学理论过渡到临床实践的必学知识,因此我国医学院校对来华医学留学生的临床技能学教育较为重视。本校教务处在国内本科生教学的基础上,通过总结既往留学生临床技能教学的经验教训,成立了专门的课程教学组(课程组),建设了以临床思维培训为导向的临床技能学课程体系,取得较好的效果,现报道如下。 | 徐元敏 刘景仑 BRYAN R S ANDREW T 亢胜男 张丹 | 2019 | 重庆医学2019，48，12： | 8 |
| 3 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022，13，7： | 2 |
