引用

Chinese Medical Journal 2022年第22期135卷 2764-2766页

作者： Bo Yin lianhua li Zheng Lu Jie Gao Huayong Zeng Yanhong Cai Yuanming He Zhi liu Department of Orthopedic Surgery Beijing Chaoyang HospitalCapital Medical UniversityBeijing 100020China Senior Department of Orthopedics the Fourth Medical Center of Chinese People's Liberation Army(PLA)General HospitalBeijing 100048China Medical Supplies Center of PLA General Hospital Beijing 100700China

To the Editor:There is controversy in the literature on the benefits of open reduction and internal fixation(ORIF)and minimally invasive plating osteosynthesis(MIPO)for mid-distal humeral shaft fractures.[1]ORIF has the advantages of anatomical reduction,strong fixation,and little impact on the function of the elbow and shoulder ***,it has some disadvantages,including the need for a large incision and more dissection of soft tissues,interrupting blood supply to the fracture site,resulting in difficulties in healing and an increased risk of bone non-union,and a high risk of iatrogenic radial nerve *** contrast,treatment of mid-distal humeral shaft fractures by MIPO has the advantages of less dissection of soft tissues,avoidance of exposure of the radial nerve,and a low risk of iatrogenic radial nerve *** study aimed to compare the medium-term safety and effectiveness of MIPO and conventional ORIF in the treatment of mid-distal humeral shaft fractures.

秸秆组成和土壤性质是秸秆腐解的重要影响因素,进而调控着秸秆还田后的土壤CO_(2)排放和土壤养分动态。本研究选取了玉米秸秆(MS)、马铃薯秸秆(PS)及其等比例混合秸秆(CS)3种秸秆类型,分别添加到3种种植模式[玉米单作(MM)、马铃薯单作(MP)和玉米马铃薯间作(I)]土壤中,进行105 d的室内恒温培养试验,以探究秸秆类型在不同环境中的CO_(2)排放及土壤化学性质变化。结果表明:土壤种植模式显著影响MS的CO_(2)累积排放量,而对CS、PS没有显著影响。与玉米和马铃薯单一秸秆的加权平均(WM)相比,秸秆混合分别增加了MM土壤中CO_(2)累积排放量和净累积排放量19.2%和19.9%。与培养前相比,MS在培养结束时增加了土壤pH和可溶性有机碳含量,但对速效磷和速效钾的影响较小,且显著低于PS和CS。当同一秸秆添加到不同作物种植模式土壤中,MP土壤的速效磷、速效钾和铵态氮含量的增幅(相对于培养前)均高于I和MM。研究表明,秸秆在土壤中的腐解与碳排放首先受碳氮比调控,而土壤种植模式的作用较小,同时这些因素均对腐解过程土壤化学性质产生显著影响。
