Objective To systematically review the efficacy and safety of mini-percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopic lithotripsy (FURL) in management of lower pole kidney stones.Methods PubMed, Embase, Scopus, Cochrane library, CNKI, VIP and Wanfang Data were searched from the beginning of database to September 2016 and clinical trials that compared the two above operation for treatment of lower pole stones were collected.Two researchers independently filtered literature,extracted data and evaluated the methodological quality of research papers.The meta-analysis was performed using the RevMan 5.3 software.Results One randomized and seven non-randomized studies were analyzed, which consists of 621 patients including MPCNL group 327 cases, FURL group 294 cases.The results of meta-analysis showed that MPCNL was better than FURL in stones clearance (OR =2.65,95％ CI 1.58-4.46,P ＜ 0.01) and operative time (WMD =-21.86,95％ CI-28.52--15.20, P ＜ 0.01).FURL was better in hospital stay time (WMD =2.28,95％ CI 0.29-4.28, P =0.02), decrease in haemoglobin levels (WMD =0.78,95 ％ CI 0.68-0.89, P ＜ 0.01), bleeding (OR =5.11,95 ％ CI 1.12-23.31,P =0.04), transfusion(OR =7.04,95％ CI 1.59-31.15, P =0.01).There was no significant difference in fever,urinary tract infection, hematuria (P ＞ 0.05).Conclusions Both MPCN and FURL are safe and effective for the treatment of lower pole stones, MPCNL can get higher stone clearance rates and shorter operation time.However, FURL can get shorter hospitalization time and lower complication rates.

Nursing students are new resources of clinical nursing service, the professional education training of competency regarding nursing quality and safety are necessary and important. This paper aims to analyze the education framework and research progress of foreign nursing quality and safety competence, and provide the references for Chinese education system of cultivating nursing students' nursing quality and safety competence in combination with current Chinese education situation.

Objective To study the effect of interlocking intramedullary nail on fixing transverse olecranon fracture. Methods Nine pairs of fresh ulna specimens were collected and the transverse fracture model of olecranon was established. Kirschner wire tension band and interlocking intramedullary nail were used to repair the fracture. Cyclic dynamic tension loads with amplitude of 25 N, mean value of 45 N and frequency of 05 Hz were applied to the triceps tendon under simulated elbow flexion conditions of 30°, 45° and 60°, respectively. The fracture displacements of specimens within 300 cycles were recorded in three groups. ResultsAt 30° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.831±0.333) mm and (3.723±2.390) mm, respectively. At 45° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.167±0.374) mm and (2.455±0.609) mm, respectively. At 60° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.407±0.342) mm and (3.112±1.025) mm, respectively. The fracture displacement of interlocking intramedullary nail was smaller. Conclusions The mechanical properties of interlocking intramedullary nail are better than those of Kirschner wire tension band, and the interlocking intramedullary nail is more stable and firmer for fixing transverse olecranon fracture. Moreover, the interlocking intramedullary nail is installed with the operating tool, thus the operation is more accurate and faster, and the operation efficiency is greatly improved.
