Objective To study the validity of continuous positive airway pressure(CPAP)curing overlap syndrome.Methods Comparisons were made in the respiratory disturbance index(RDI)the longest apnea time the longest hypopnea time etc between before and after-treatment.Results The respiratory disturbance index(RDI)、the longest apnea time、the longest hypopnea time were signifi- candy different(P＜0.05).Conclusion Continuous positive airway pressure is an effective method to treat overlap syndrome.

OBJECTIVETo compare the clinical effects of different surgical methods for the epicanthus corrective surgery.

METHODSCanthoplasty with asymmetric Z-flap is applied in 46 cases, Y-V advancement procedure for epicanthoplasty is applied in 42 cases. The epicanthus aesthetic measurement were measured and calculated by software before and after surgery, the diameter of the iris was measured as a reference value,and the postoperative scar was assessed by VSS scale. At the same time, by measuring the lateral canthal distance, the accuracy of the measurement method can be verified.

RESULTSAll patients were satisfied with the long-term results and there were no recurrences of the epicanthal fold. The shortening ratio of the ICD is 8.36% in the group with the Z-plasty, and 5.88% in Y-V plasty. the lateral canthal distance have no diffrence before and after surgery.

CONCLUSIONSTwo surgical methods can get good results. The magnitude of correction in Z-plasty may larger than Y-V plasty, but postoperative retraction may existed in Z plasty.

Objective To investigate the correlation between the frustration tolerance and personality of medical college students and to discuss its promoting strategies.Methods Totally 460 college students were selected randomly.Questionnaire of frustration tolerance and scale of Eysenck personality inventory(EPQ) were used and the measurement data were compared with correlation analysis and regression analysis of SPSS 13.0.Results Correlation was significant between frustration tolerance (total score and 6 inducing factors) and personality (EPQ factors) of college students ； personality (EPQ factors)of students could predict their frustration tolerance and corresponding t value was -4.85,P ＜ 0.01 (psychoticism),6.93,P ＜ 0.01 (extraversion),-11.15,P ＜ 0.01 (neuroticism).Conclusions Personality of college students are greatly influenced by their frustration tolerance.Targeted anti-frustration ability training should be conducted according to the different personality characteristics.

Objective To investigate the effects of low dose radiation on the level of oxidative damage and antioxidant in population of high background radiation area of Guangdong.Methods A total of 48 male residents who lived in high background radiation area(HBRA) of Guangdong province and 48 male residents who lived in neighboring Enping control area were chosen as the objectives and control respectively.The peripheral venous blood of two groups was collected,and then the levels of 8-OHdG and TrxR were determined by enzyme linked immunosorbent assay (ELISA).Results Compared with the CA group [(315.39 ± 100.59) ng/ml],the level of 8-OHdG [(272.64 ± 96.85) ng/ml] decreased significantly in HBRA (t =2.121,P ＜0.05).Compared with the CA group [(0.467 ±0.056) ng/ml],the level of TrxR [(0.496 ± 0.044) ng/ml] increased significantly in HBRA (t =-2.823,P ＜ 0.05).The results of multiple linear regression analysis demonstrated that the chronic exposure to low dose of radiation had significant effects on the expression level of 8-OHdG and TrxR (t =-2.327,2.367,P ＜ 0.05) after adjustment for confounding factors such as age,drinking,tea drinking,smoking,medical exposure and stressful events.Conclusions Chronic exposure to low dose radiation may decrease the level of oxidative and enhance the level of antioxidant.

Objective To investigate the in vitro susceptibility of Minocycline and polymycin B against clinical islates of pan-drug resistant Acinetobacter baumanii ,to provide laboratory support for clinical treatment for drug selection.Methods The susceptible test of Minocycline and polymycin against 39 isolates of pan-drug resistant Acinetobacter baumanii were determined by K-B meth-od.Results 38 strains of pan-resistant Acinetobacter baumanii were sensitive to polymyxin B,sensitive rate was 97.4%,20 strains sensitive to minocycline,the sensitivity rate was 51.3%.polymyxin B sensitivity was more sensitive than Minocycline (P < 0.05). Conclusion Polymycin B had strong activit ies against pan-drug resistant Acinetobacter baumanii .

Objective To investigate the association of serum angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) with myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods A total of 103 consecutive STEMI patients who received primary PCI were enrolled in this study. The patients were divided into two groups according to ST-segment resolution (STR) at 2 h after PCI:STR ≥ 50%group (n=69) and STR<50%group (n=34). Serum concentrations of Ang-1, Ang-2 and Ang-2 to Ang-1 ratios (Ang-2/Ang-1) before and immediately after PCI, 2 h, 6 h, 24 h after PCI were compared. Predictors of poor STR were identiifed by multivariable logistic regression analysis. Results The patients with STR≥50%had significant higher serum Ang-1 levels (P < 0.05) and lower Ang-2/Ang-1 ratios (P < 0.01) from before PCI to 6 h after PCI than those with STR < 50%;Ang-1 and Ang-2/Ang-1 at 24 h after PCI, and Ang-2 at all time points were not signiifcantly different between the two groups (P>0.05). In multivariable logistic regression analysis, Ang-2/Ang-1 before PCI was independently associated with STR < 50%;Other independent predictors were pain to balloon time, infarct related artery (LAD), and TIMI flow grade<Ⅲafter PCI. Conclusions Higher Ang-2/Ang-1 is an independent predictor of poor myocardial reperfusion in STEMI patients after PCI.

The rise of advanced nursing practice in the developed countries promotes the development of nursing science, nursing postgraduate education arises at the historic moment. Professional nursing postgraduate education started late in our country and its development is not mature, there exists some problems in the training plan and professional positioning, such as training process not realizing the training objectives, unreasonable curriculum setting and evaluation system, unclear professional direction, disconnection of vocational orientation and the professional qualification and specialist nurse certification. Therefore, nursing professional degree graduate education mode needs further exploration and unity.
