Objective To discuss the effect of rehabilitation nursing for total knee arthroplasty by discussing hospitalization expenses and its factors of rehabilitation nursing.Methods 305 patients who were underwent total knee arthroplasty from 2011 to 2013 were recruited and recovered according to rehabilitation nursing and training requirements established by our hospital.Patients admitted in 2011 were designated as control group.The comparison of American knee society knee score and knee rang of motion of patients were made and analyzed.Results The annual comparison of sores of pre-and post-operative KSS (t=5.30,7.99,11.20),and knee ROM of patients (t=8.21,4.57,7.86) showed that the difference was statistically significant (P＜0.05).The total costs and rehabilitation nursing expenses inreased year by year (P＜0.05).The proportion of rehabilitation and rehabilitation nursing expenses each year were 5.77％ (3 157/54 679),4.60％ (2 847/61 831),5.15％ (3 341/64 930) and 0.51％ (280/54 679),0.64％ (393/61 831),0.52 ％(338/64 930),respectively.Conclusions Pre-and post-operative correct rehabilitation exercises are one of the most important guarantee of curative effect.There is a lower percentage of rehabilitation nursing expenses in total costs,and the value of the nursing staff has not been fully reflected.

Objectives To investigate the rational treatment strategy of hepatoblastoma (HB) in children. Methods Clinical data and follow-up of 25 children with HB admitted from February 2009 to March 2013 were retrospectively analyzed. Results Twenty-five children with newly diagnosed HB (14 males and 11 females) were enrolled. The median age on diagnosis was 25 months (3-92 months);In 18 of 25 cases with complete resection of the primary tumor, 17 cases survived. Only 1 of 7 cases with incomplete resection survived. The survival rate in children with complete resection of primary tumor is significantly higher than those without complete resection (P<0.05). The survival rate in children of stage I or II is significantly higher than the children of stage III or IV (P<0.05). Conclusions Complete tumor resection is the cornerstone of therapy for long-term disease-free survival in HB patients. Treatment strategy remains to be further improved for children with recurrent and metastatic HB.

Objective To lateralize epileptic foci in interictal electroencephalography (EEG) signal by using causal analysis method.Methods On the basis of frequency domain causal analysis,the adapted directed transfer function (ADTF),power spectrum weighted ADTF(psADTF) method was proposed by applying the power spectrum information in defined frequency band with normalized ADTF,to fit the frequency information features of different epileptic wave.EEG signals of two groups of 30 epilepsy patients were analyzed by psADTF.Group Ⅰ included 15 presurgical patients and 104 epilepsy spikes were picked from EEG signals.Group Ⅱ included 15 outpatient patients and 98 epilepsy spikes were picked from EEG signals.Results 96 of 104 spikes of group Ⅰ were lateralized properly by psADTF according to surgery sites,and the accuracy rate was 92％.94 of 98 spikes of group Ⅱ were lateralized properly by psADTF according to three technicians' judgments,with the accuracy rate of 96％.Conclusion Our results proves that the psADTF method over interictal EEG spikes can be a great help to clinical epileptic foci lateralization.

Objective To investigate the relationship between peripheral blood mtDNA content and acute coronary syndrome. Methods A total of 244 patients who received coronary angiography(CAG)was enrolled in this study. They were divided into acute coronary syndrome(ACS)group(n=183)and control group(n=61)ac-cording to the CAG results. A quantitative real-time PCR-based method was used to measure relative content of mtDNA in peripheral blood. According to lesion blood vessel counts ,ACS patients were divided into single lesion group,double lesion group and three lesions group. Gensini score was used to quantitatively evaluate the severity of coronary stenotic lesions. Then we analyzed the relationship of mitochondrial DNA content with the lesion counts and the Gensini score. Results The ACS group had a lower mtDNA content ,as compared to controls (P <0.001).The lesion blood vessel count and mtDNA content in the single ,double and three vascular lesions group were all significanlty lower than that of the control group(P<0.05)and that of the double,three vascular lesions group were both significantly lower than that of the single vascular lesion group(P<0.05). According to the Gensi-ni score,all patients were divided into four groups,where with mtDNA content was decreased with the increase of the Gensini score(P < 0.01). The linear regression analysis showed that Gensini score was negatively correlated with mtDNA content(r=-0.644,P<0.001). ROC curve analysis showed that the area under the curve of mtDNA content for ACS diagnosis was 0.855(P<0.001),with the sensitivity and specificity of 0.756 and 0.833,respec-tively. Conclusion MtDNA content is closely associated with ACS and the Gensini score ,the latter indicating the severity of coronary stenotic lesions. MtDNA content detection has its value in the diagnosis of ACS.
