BACKGROUND:With the development of AO, the treatment of intercondylar humeral fractures with open reduction has been a trend. However, the methods of fixation become many. There is no conclusion of which method is optimal.
OBJECTIVE:To investigate the clinical effect of two kinds of different fixation methods (Y-type steel plate and double steel plate) for intercondylar humeral fractures via different surgical approaches.
METHODA retrospective analysis of clinical data of 86 cases of fresh intercondylar humeral fractures in the Department of Orthopedics, Sixth Affiliated Hospital, Xinjiang Medical University, between December 2003
and May 2014 were conducted in this study. According to the different fixation materials, patients were divided into two groupdouble steel group (n=44, including the surgical approach of ulna olecranon osteotomy which had 22 cases and the surgical approach of triceps V shaped severance which had 22 cases), Y-type steel group (n=42, including the surgical approach of ulna olecranon osteotomy which had 21 cases and the surgical approach of triceps V shaped severance which had 21 cases). The clinical curative effect and related complications of the two groups after operation were analyzed. During fol ow-up, modified Cassebaum elbow scoring system was used to evaluate the excellent and good rate of therapy.
RESULTS AND CONCLUSION:After fol owed up for 12-36 months, the total excellent and good rate of Y-type steel plate was 76%and the total excellent and good rate of double steel plate was 77%. There were no significant differences between the two groups (P>0.05). But interestingly, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance and the difference was statistical y significant (P<0.05). Above data suggested that Y-type steel plate and double steel plate were effective ways in the repair of intercondylar humeral fractures. However, for different surgical approaches, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance.

Objective:To explore the relationship among lottery buying behaviors,risk attitudes and lottery re-lated cognitive distortions,in order to propose suggestions about the intervention of problem lottery players and the healthy development of the lottery.Methods:Totally 228 lottery players (120 males,108 females;150 unmarried,78 married)sampled from Jinan were asked to fill out the Questionnaire of Lottery Buying Behavior (LBB),Domain Specific Risk-Taking Scale (DOSPERT)and Lottery Related Cognitive Distortions Scale (LRCD).Correlation a-nalysis and path analysis were used to analyze the data.Results:The scores of irrational behavior of LBB were posi-tively correlated with the DOSPERT total scores and its factor scores of recreation and gambling,and positively cor-related with the LRCD total scores and its factor scores except optimistic (r=0.17 -0.34,Ps<0.01 ).While the scores of rational behavior of LBB were negatively correlated with DOSPERT total scores and factor scores of rec-reation and gambling,and negatively correlated with LRCD total scores and its factor scores of illusion of control, illusory correlation,over optimistic and gamblers'fallacy (r=-0.18 --0.37,Ps<0.01 ).Path analysis showed that lottery related cognitive distortions had complete mediating effect between risk attitudes and irrational behaviorsof buying lotteries.Lottery related cognitive distortions partially mediate the relationship between risk attitudes and rational behaviors of buying lotteries.Conclusion:It suggests that the higher risk attitudes the lottery players hold, the greater cognitive distortions they will have,which in turn the irrational behaviors of buying lotteries might easily to have.

Objective To investigate the safety and efficacy of surgery in 121 patients with spinal metastases.Methotds A retrospective analysis of clinical data from April 2009 to March 2013 was performed in 121 patients with spinal metastases.From 37 to 65 years,69 males and 42 females with mean age of 55.6 years.Primary tumor origin:Lung 35(28.9％),Breast 26(21.4％),Renal 17 (14.0％),Prostate 20 (16.5％),Thyroid 14 (11.6％),Liver 2 (1.7％),Colon 1 (0.8％),other 6 (5.0％).All patients received surgery.Follow-up and survival time were analyzed.In preoperation and postoperative 3 month,pain levels were assessed by visual analogue scale (VAS),neurologic deficit was evaluated by Frankel Grade and functional impairment was classified by Karnofsky Score.The quality of the life was assessed by EORTC QLQ-C30 questionnaire.Survival analysis was evaluated by Kaplan-meier.Results The period of follow-up ranged from 5 to 35 months with the average of 15.9 months.The mean survival was 14.5 months.1-year survival was 53.5％.2-year survival was 36.5％.In patients with lung cancer,the mean survival was 8.5months.1-year survival was 14.3％.2-year survival was 11.4％.In patients with breast cancer,the mean survival was 31 months.1-year survival was 57.7％.2-year survival was 46.2％.In preoperation and postoperative 3 month,the VAS showed statistical significance (t=21.6,P＜0.01) ;Post-operatively,80.3％ of all patients had functionally useful Frankel Grade D or E compared with 43.5％ pre-operatively.KPS score (80-100) percentage was 75.6％ postoperatively compared with 33.4％ preoperatively.In 1month postoperatively,35 of 75 patients who were sphincteric dysfunction preoperatively were improved.The EORTC QLQ-C30score was 83.39±7.23 in preoperation and 51.34±14.27 in postoperaion.The quality of life was impoved significantly (t=12.6,P＜0.01).Conclusion Surgical treatment was effective in improving quality of life by providing better pain control,enabling patients to regain or maintain mobility,and offering improved sphincter control.In all patients,the number of patents with spinal metastases from breast and lung cancer is higher.Compared with spinal metastases from breast cancer,the proportion of lung cancer origin received surgery is higher.

Objective To know the situation of teaching and teacher preparation for nursing under-graduates, and then reference to reasonable clinical teaching mode. Methods Investigated clinical pre-ceptors from 30 hospitals by serf-designed questionnair to know their basic situation, and then investigated nursing undergruaduates who had enter school in 2004 to know their evaluation about their preceptors in the aspect of basic quality. Results In professional tides, most of the teachers are nurse-in-charge, and have been working over 10 years, but qualification certificates levels were low and 50% of them teaching. Experience was short and not qualified to the popurse of bachelors degree, nurse-in-charge and more than five years nursing experience. The ratio in thesis writing, teaching training and awards are rather low. There were teaching assessment from students, mainly in teaching and research initiative. Conclusions The qualities of nursing teachers should be defined and should be established standard teaching training system and qualification organization, the capabilities of teaching and research innovations should be improved.

ObjectiveTo investigate the safety and efficacy of combined treatment with subtotal corpectomy and radiofrequency ablation(RFA) for spinal metastases. MethodsFrom April 2009 to March 2010, 29 patients with spinal metastases who received subtotal corpectomy were analyzed. Sixteen patients (7 men and 9 women) with an average of 57.8 years having received subtotal corpectomy alone were selected for comparison (the subtotal corpectomy group). Thirteen patients (7 men and 6 women) with an average of 58.3 years having received subtotal corpectomy combined with RFA were chosen as subjects of this study (the RFA combination group). There were no significant differences between the two groups with respect to the patient's age, gender, and Tomita type. Pain levels pre-and post-procedure were assessed by the visual analogue scale(VAS), and neurologic deficit were evaluated by the Frankel scale. ResultsThe VAS in RFA combination group were 8.88±0.36, 3.76±0.33, 3.35±0.38 in preoperation, 1 month, and 6 months postoperatively, respectively. The VAS in subtotal corpectomy group were 8.96±0.39, 3.81 ±0.48, 3.41 ±0.42 in preoperation, 1 month, and 6 months postoperatively, respectively. The VAS in both groups showed statistical significance at each time point, there was no statistically difference between the two groups. The operate time in RFA combination group and subtotal corpectomy group were(216.54±113.77) min and(302.50±80.44)min, respectively. The blood loss of the two groups were (1084.62±539.82)ml and (1625.00±724.34)ml, respectively. The recurrent rate of the two groups were 30.8％ and 75.0％, respectively. The RFA combination group were lower in operate time, blood loss and recurrent rates than subtotal corpectomy group. Conclusion Compared with the subtotal corpectomy, the RFA combination can reduce the blood loss, operation time, and the recurrent rates.

Objective:To investigate the safety and efficacy of laminectomy combined with vertebroplasty in spinal metastases from rapid-growth tumors. Methods:Clinical data of 23 patients with spinal metastases of lung cancer, who were admitted to the Cancer Hospital from July 2008 to May 2012, were retrospectively analyzed. Thirteen male and ten female patients, with an age range from 40 years to 65 years and a mean age of 51.5, were examined. All patients received posterior laminectomy to relieve spinal cord compression. Afterward, vertebroplasty combined with radiofrequency ablation was conducted, followed by the internal fixation of vertebrae (instrumental fixation). Operation time, blood loss, and bone cement leakage rate were analyzed. One month before and after the operation, pain measurement was conducted using visual analog scale (VAS) and neurologic deficit (spinal cord injury) by Frankel Grade. Functional impairment was classified by Karnofsky performance status (KPS) score. Quality of life was assessed by the European Organization for Research and Treatment questionnaire (EORTC QLQ-C30). Results:The mean operation time was 163±87.36 min. Blood boss was 430±130.35 mL. Bone cement leakage rate was 21.7%. One month before and after surgery, the VAS showed statistical significance (t=25.6, P<0.01). After surgery, 78.3%of all patients exhibited functionally satisfactory Frankel Grade D or E, compared with 43.5%of patients before the operation. KPS score (80 to 100) percentage was 69.6%after surgery compared with 34.8%before surgery. One month after the operation, remission of various degrees was seen in 10 of 18 patients who had sphincteric dysfunction before surgery (55.6%). The EORTC QLQ-C30 score was 85.39±8.99 before and 52.78±15.17 after operation. The quality of life improved significantly (t=11.6, P<0.01). Conclusion:Posterior laminectomy and vertebroplasty combined with radiofrequency ablation for spinal metastases from lung cancer is safe and effective. The treatment can improve pain, function, and life quality of patients with lung cancer spinal metastases.

Objective:Prostate cancer frequently metastasizes to the spine. In this study, we investigate the prognostic factors as-sociated with survival in patients with prostate cancer accompanied by spinal metastases at their preliminary diagnosis. Methods:Clin-ical data of 49 patients who were diagnosed with spinal metastasis from prostate cancer between January 2005 and December 2010 were analyzed. Variables including alkaline phosphatase (ALP), previous skeletal-related event, Gleason score, prostate-specific anti-gen (PSA) nadir, and time to castration resistance were obtained. Moreover, the relationship between these variables and overall sur-vival (OS) was analyzed. Survival analysis was performed by using Kaplan-Meier curves. Furthermore, the differences among the OS rates were assessed by using the log rank test. The variables were statistically significant in the univariate analysis (P<0.05) and were included in the multivariate model. Results:The average follow-up time was 64.1 months among the 49 patients. By the end of the follow-up, 41 of these patients were dead;the mean survival was 27 months. The 1-, 3-, and 5-year survival rate was 81.6%, 40.8%, and 20.4%, respectively. Univariate analysis identified that 6 variables were statistically significant prognostic factors of OS:with or without chemotherapy, ALP, previous skeletal-related event, Gleason score, PSA nadir, and time to castration resistance. The multivari-ate analysis showed that the time to castration resistance of ≥19 months and the addition of chemotherapy after disease progression are independent prognostic factors for a high OS. Conclusion:With or without chemotherapy and the time to castration resistance are the independent prognostic factors associated with survival in patients with prostate cancer accompanied by spinal metastases at first diagnosis.
