Objective To explore the effects of dialectical nursing on recurrent oral ulcers in children. Methods One hundred and eighty-eight cases of children with recurrent oral ulcer hospitalized from March 2013 to June 2015 were randomized into study group and control group using random digit table with 94 cases in each group. The control group was intervened with the modern medical care pattern and the study group was with dialectical nursing care of Chinese medicine besides the modern medical care pattern. The two groups were compared in terms of the curative effect, time for ulcer healing, pains and level of the children′s and parents′satisfaction. Results The curative effect in the study group was significantly better than that of the control group (P<0.01). The time of the study group was shorter than that of the control one (P<0.001). The level of pains was lower but the degree of satisfaction was higher than that in the control group (all P<0.01). Conclusions The dialectical nursing care combined with modern medical care pattern is effective in treating recurrent oral ulcers in children. It can shorten the healing time and enhance the satisfaction. It can have high value of clinical application and promotion.

Objective To compare the treatment effectiveness of AO/ASIF proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA) in treatment of intertrochanterie fractures. Methods A retrospective study was done on 233 patients with intertroehanteric fractures treated from August 2004 to December 2006. The patients were divided into PFN group (188 patients) and PFNA group (45 patients) for comparing operative procedures and postoperative functional recovery. Results There was statistical difference in aspects of incision length, blood loss and operation time between two groups. The follow-up for 22.8 months showed excellence rate of 89.9% in PFN group and 91.1% in PFNA group, with statistical difference (X2 = 0.06, P > 0.05). There occurred hip varus in one patient and antirotation nail cutting-out in two in PFN group, which was not found in PFNA group. Conclusion PFN and PFNA are both good choices for treatment of intertrochanteric fractures. Compared with PFN, PFNA has more advantages in reducing operation time and blood loss especially for the eider patients with osteoporosis.

Objective To study the survival status of very elderly patients with intertrochanteric fracture admitted in hospital and its risk factors.Methods Clinical data of 54 patients with intertrochanteric fracture aged 90 years and over admitted in hospital from Jan.2006 to Dec.2013 were retrospectively analyzed.5 patients were lost to follow-up.The survival status of patients was analyzed.Results Patients were followed up until January 2015.The period of follow-up ranged from 85 months to 0.2 months,with an average follow-up of 33.3 months.17 cases were survived.Harris scores were(61.2 ± 10.6).The overall 1-,3-,5-year survival rates were(0.88 ± 0.05),(0.35 ±0.08),(0.18 ± 0.08),respectively.The mean and median survival times were (33.3 ± 4.6) months and(25.0±5.4) months.Cox proportional hazard regression model showed that American Society of Anaesthesiologists(ASA) score,operation time and the number of comorbidities were the risk factors for the survival time of very elderly patients with intertrochanteric fracture (all P ＜0.05).Conclusions Compared with conservative treatment,surgical treatment can increase the survival time of the elderly patients with intertrochanteric fracture.ASA score,operation time and the number of comorbidities may be the risk factors for the survival time of very elderly patients with intertrochanteric fracture.
