ObjectiveTo discuss the effect of evidence-based nursing in improvement of unhealthy emotion and treatment compliance of patients undergoing painless gastroscopy. Methods134 patients from May 2008 to December 2010 undergoing painless gastroscopy were chosen as study object.According to voluntariness of the patients and their families,they were divided into the evidence-based nursing group (70 cases) and the routine psychological care group (68 cases).The satisfaction degree with nursing,unhealthy emotion,and the compliance during treatment process were evaluated with SAS and SDS.ResultsThe satisfaction degree of patients in the evidence-based nursing group was 92.86％,higher than 79.41％ in the routine psychological care group.No significant difference was shown in SAS and SDS score before treatment between two groups,but unhealthy emotion and treatment compliance after treatment significantly improved,and the improvement degree of the evidence-based nursing group was more evident. ConclusionsApplication of evidence-based care model in painless gastroscopy has more obvious advantages in improvement of unhealthy emotions and treatment compliance compared with routine nursing.It has more important value for clinical practice and is more conducive to improve the quality of life of patients.

OBJECTIVETo evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy.

METHODSFrom January 2009 to June 2010,34 patients with anterior or posterior cruciate ligament injuries were divided into two groups : group A and group B. There were 24 patients in group A, including 19 males and 5 females,with an average age of (31.83±9.57) years old. The patients in group A were treated with anterior cruciate ligament reconstruction under arthroscopy; Rigidfix cross pins and Intrafix pins were used to fix femoral and tibial side respectively. Among the 10 patients in group B, 8 patients were male and 2 patients were female, with an average age of (27.20+7.59) years old. The patients in group B were treated with posterior cruciate ligament reconstruction under arthroscope; Intrafix pins and Rigidifix cross pins were used to fix femoral and tibial side sepectively. The drawer test and Lachaman test were used to evaluate postoperative knee stability. All the patients were followed up at least 18 months. Lysholm and Tegner knee scores were used to evaluate the clinical therapeutic effects.

RESULTSAll the 34 patients were followed up, and the duration ranged from 18 to 26 months,with an average of (20.79±2.39) months. All the patients obtained good pain relief and knee stability. In group A,Lysholm scores significantly increased from 43.04±7.57 preoperatively to 85.41±4.68, 92.50±3.05, and 93.45±2.57 at 6,12, and 18 months postoperatively; Tegner scores significantly increased from 2.62±0.92 preoperatively to 7.45±1.14, 8.58±0.77, and 8.95±0.55 at 6, 12, and 18 months postoperatively. In group B,Lysholm scores significantly increased from 46.20±8.27 preoperatively to 86.40±5.14,90.40±2.67,and 92.00±3.85 at 6,12,and 18 months postoperatively ;Tegner scores significantly increased from 2.00±0.66 preoperatively to 7.10±0.99, 8.60±0.84, and 8.80±0.42 at 6,12, and 18 months postoperatively. There were no differences in Lysholm and Tegner scores between group A and B at different times during follow-up. Lysholm scores of all patients significantly increased from 43.97±7.79 preoperatively to 85.70±4.76,91.88±3.06,and 93.02±3.01 at 6,12,and 18 months postoperatively. Tegner scores of all patients significantly increased from 2.44±0.89 preoperatively to 7.35±1.09, 8.58±0.78, and 8.91±0.51 at 6,12,and 18 months postoperatively. During the follow-up period,there were no serious immunological rejection and complications.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.

METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.

RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.

CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.
