ABSTRACT
Objective:To evaluate the intervention effect of Naikan cognitive therapy (NCT)on psychosomatic symptoms of female compulsory drug addicts.Methods:Seventy drug addicts who met the inclusion criteria and volunteered to participate in the study were selected and randomly divided into intervention group( n=35) and control group( n=35) with random number table method.The intervention group received 10 consecutive days of NCT, while the control group received the same period of mental health education.Before and after treatment, the two groups were assessed with symptoms check list-90(SCL-90), preceived social support scale(PSSS), simple coping style scale(SCSQ) and inclination of relapse questionnaire of drug rehabilitated addicts. Results:There was no significant difference between the two groups before the intervention (all P>0.05). Compared with pre-intervention, the total score of SCL-90((176.49±40.85) vs (152.60±31.17)), somatization, compulsion, interpersonal sensitivity, depression, anxiety, terror, paranoid and psychiatric factors were significantly decreased and the total scores of PSSS((59.09±14.60) vs (64.43±10.42)) family support, friend support and other support subscales increased significantly post-NCT intervention in the intervention group (all P<0.05). Compared with control group, the scores of positive coping((25.54±6.09) vs (22.37±7.04)) increased significantly, and the tendency of negative coping((8.20±3.59) vs (10.17±4.03)) and relapse((15.66±9.57) vs (22.11±10.18)) decreased significantly (all P<0.05) after intervention in the intervention group.There was no significant difference in the scores of all scales in the control group (all P>0.05). Conclusion:Naikan cognitive therapy can significantly improve the psychosomatic symptoms perceive social support and positive coping styles, and reduce the tendency of negative coping and relapse of female compulsory drug addicts.
ABSTRACT
To investigate the effect of treatment on prognosis of patients with different timing of early interventional treatment for non-ST segment elevation acute myocardial infarction [NSTEMI]. Forty two cases above 75 years old, diagnosed with high-risk on NSTEMi, were selected in cardiology department of Xinxiang central hospital. They were randomly divided into two groups: 22 in group A and 20 in group B. Group A was performed PCI surgery within 12 hours after the onset while group B from 12 to 24 hour after the onset. Major adverse cardiovascular events [including death, heart failure readmission rates after ischemia, malignant arrhythmias, again target vessel revascularization] and bleeding data were recorded at the three terms of hospitalization, one month after the onset and six months after the onset. Angina, malignant arrhythmia and heart failure during hospitalization can be reduced after interventional treatment carried out within 12 hours after the onset. Readmission rates after ischemia, heart failure and the incidence of death can be significantly reduced after interventional treatment carried out during 1-6 month after the onset with no significant increase in bleeding rate. In the treatment of elderly patients with NSTEMI, early interventional treatment is safe and effective
ABSTRACT
BACKGROUND:The analysis of gas flow in upper respiratory tract of patients with obstructive sleep apnea-hypopnea syndrome contributes to further understanding the correlation of anatomical structure and function of upper respiratory tract so as to know the pathogenesis of obstructive sleep apnea-hypopnea syndrome. OBJECTIVE:To establish the three-dimensional computational fluid dynamics model of upper airway in patients with obstructive sleep apnea-hypopnea syndrome, to study the characteristics of airflow dynamics in upper respiratory tract in above patients, and to lay the foundation for further exploring the pathogenesis of obstructive sleep apnea-hypopnea syndrome. METHODS:CT scan of the upper airway was performed with a moderate obstructive sleep apnea-hypopnea syndrome patient. Data stored in DICOM format were imported in Mimics 10.01 software, and processed, and then computational fluid dynamics model was built. ANSYS ICEM CFD14.0 was used to perform the grid division of the three-dimensional model. The internal flow of upper respiratory tract was simulated by ANSYS 14.0-Fluid Dynamics, and relevant information on airflow field of upper airway was obtained. RESULTS AND CONCLUSION: The three-dimensional computational fluid dynamics model of upper airway wasestablished with 1 751 940 elements and 303 981 nodes of upper airway. The flow rate was 11.087 m/s in the lower bound of pharyngopalatiae, which was the most narrowed areas of upper airway in patients with obstructive sleep apnea-hypopnea syndrome. The three-dimensional computational fluid dynamics model of upper airway has accurately simulated biomechanical feature of human, which provides a foundation for further studying the airflow dynamics of upper respiratory tract of patients with obstructive sleep apnea-hypopnea syndrome.

ABSTRACT
Gait recognition is a new technology in biometric recognition and medical treatment which has advantages such as long-distance and non-invasiveness. Depending on the differences between different people's walking pos tures, we can recognize individuals by characteristics extracted from the images of walking movement. A complete gait recognition process usually includes gait sequence acquisition, gait detection, feature extracting and recognition. In this paper, the commonly used methods of these four processes are introduced, and feature extraction methods are classified from different multi-angle views. And then the new algorithm of multi-view emerged in recent years is highlighted. In addition, this paper summarizes the existing difficulties of gait recognition, and looks into the future development trends of it.

ABSTRACT
BACKGROUND: There are a lot of controversies regarding the choice of short versus long segment pedicle screw fixation for the treatment of isthmic spondylolisthesis and degenerative spondylolisthesis treatment. OBJECTIVE: To investigate clinical efficacy of short versus long segment pedicle screw fixation in treatment of lumbar spondylolisthesis.METHODS: A total of 146 spondylolisthesis patients were included in this study, 36 males and 110 females, aged 22-73 years at a mean of 53 years; disease duration was from 1 to 18 years at a mean of 5 years. These patients were treated with lumbar spinal window-opened decompression or laminectomy decompression, a short or long segment pedicle screw internal fixation, transverse interbody fusion.RESULTS AND CONCLUSION: Among 146 involved patients, 72 cases were treated with four pedicle screw fixation (short segments), while 74 cases with six pedicle screw fixation (long segments). Interbody graft was performed in 101 cases, while intertransverse fusion given in 45 cases. Totally 134 cases were followed up for postoperative 1.5-14 years. According to clinical grading standards of Steffee system, the clinical efficacy was assayed excellent in 74 cases, good in 41 cases, mild in 13 cases and poor in 6 cases, with good rate of 85.8%. 77 cases achieved a complete reduction, including 32 cases using a short segment fixation and 45 cases using a long segment fixation. 69 cases achieved partial reduction, including 40 cases using a short segment fixation and 29 cases using a long segment fixation. Pedicle screws ruptures were found in 13 screws of eight patients undergoing short segment fixation, while no pedicle screw fracture was found in long segment fixation. Choice of short or long segment for the fixation is based on the analysis of spondylolisthesis type, severity, duration of disease, emergence of adjacent segment disc degeneration and instability.
ABSTRACT
[Objective] To evaluate the clinical value of diagnosing osteoporosis with vertebra bone mineral density(BMD) by measurement with quantitative computed tomography (QCT) . [ Method] BMD in of lumbar vertebrae (L<,1～4>)were measured by QCT in 53 healthy middleaged persons or elderly persons (group A) and 68 osteoporosis patients ( groupB) . [Result] BMD in group A declined obviously as age increasing with significant differences (P<0. 01) . In group B,all 68 patients showed osteoporosis according to the diagnostic standard of BMD≤x -2. OSD. Sixty patients showed osteoporosis ifthe diagnostic standard was set to BMD ≤ x -2. 5SD. The BMD values of different age group was lower than the bone quantityblock values. [Conclusion] As a method for diagnosing osteoporosis, QCT has advantages of high sensitation, being precise,being reproducible and is easy for applying. It would be more practical and could decrease mis - diagnosing if the diagnosticstandard was BMD≤x-2.OSD.
ABSTRACT
Radial Basis Function Neural Network Based on Plate Model （P-RBFNN） is constructed for resolution of chromatographic peaks of unknown components number. Then a two-phase sorting genetic algorithm (TP-SGA)-training structure and evolving is intruduced to train the network so that it has the ability of re-constructed structure. TP-SGA has robustness and random globe optimization. The alternate use of gradient descent and TP-SGA makes the network have the ability to learn structure, therefore makes itself adaptable to resolution of the chromatographic peaks of unknown components number. The method proposed here needs no artificial interference, not only has it robustness and globalism. With its characteristics related above and its ability of decomposing and analysing, this method has obvious advantages comparing with others.
