The static balance test and training equipment has been used over ten years in our country. Because balance function of patients can be assessed objectively and quantitively and pertinent taining can be performed with balance equipment, this instrument has a abroad domestic application. The application of balance equipment in clinical rehabilitation is sumarized in this article.

Objective To evaluate the difference of myocardium strain between myocadial infarction and ventricular aneurysm (VA) by two-dimensional speckle-tracking imaging in rabbits.Methods 26 healthy New Zealand white rabbits were enrolled in this study,6 were put into the control group and 20 in the experimental group.models of myocardial infarction concomitant with VA were prepared by the ligation of the middle segment of left anterior descending artery and left circumflex artery.At 4 weeks after the procedure,according to the pathological inspect and echocardiography for whether VA formed,the experimental animals were divided into the VA group and the myocadial infarction group.Echocardiography was performed to measure the LV cavity size and cardiac function.Radial strain rate (SrR) and circumferential strain rate(SrC) indexes were measured by 2D-STI software for each animal at the level of apex in left ventricular short-axis view,and then calculated the strain rate decrease percentage in each segment.Results 1)Compared with the control group,SrR-S,SrR-E,SrR A,SrC-S,SrC-E,SrC-A in all segments were reduced significantly in the VA group and the myocadial infarction group (P ＜ 0.05),the VA group was the most significant.2)Compared with the myocadial infarction group,the strain rate decrease percentage of SrR-S,SrR-E,SrR-A,SrC-S,SrC-E,SrC-A in all segment had significant in the VA group.Comparison between the each section,the strain rate decrease percentage of SrR-Santerior wall,SrR-Sateral wall,SrC-Santerior wall,SrC-Slateral wall were the most significant.3)There were the tighter relationship between the strain rate decrease percentage of SrR-Santerior wall,SrC-Santerior wall,SrR-Slateral wall,SrC-Slateral wall and left ventricular ejection fraction (r =0.82,0.72,0.75,0.71,repectively,all P ＜ 0.05).4) The ROC curve analysis showed that when the strain rate decrease percentage was 60％ as the critical point,the strain rate decrease percentage of SrC-Santerior wall,SrC-Slateral wall,SrR-Santerior wall,SrR-Slateral wall had a sensitivity of 83.30 ％,84.40％,83.30％,67.70％％ and a specificity was 73.60％,78.20％％,69.70％,83.30％ for prognosis ventricular aneurysm,repectively.Conclusions After ventricular aneurysm formation,anterior and lateral wall myocardial strain were give priority to the myocardial mechanics reconstruction,thus systolic myocardial strain rate decrease percentage can be important indicator of infarction myocardial developing into ventricular aneurysm.

Objective To investigate the genetic association of complement factor B (CFB)gene polymorphisms with the susceptibility and prognosis of IgA nephropathy (IgAN).Methods Four hundreds and sixty-three Northern Han Chinese patients with IgAN and two hundreds and ninty-six geographically and ethnic matched healthy volunteers were recruited.Peripheral blood was collected from recruited individuals for DNA extracting.After amplified by plymerase chain reaction (PCR),genotyping of the four single nucleotide polymorphisms (SNPs) in CFB gene,which were rs4151667,rs12614,rs641153 and rs117314762,were performed by sequencing.Differences of allele and genotype frequencies were analyzed between IgAN patients and healthy controls.Moreover,the association between these SNPs and disease clinical manifestation,pathological features and long term renal outcome in IgAN patients were further analyzed.Results The G allele and GG genotype frequencies of rs117314762 in CFB gene were significantly higher in IgAN patients than that in healthy controls.No difference in allele and genotype frequencies of rs4151667,rs12614,rs641153 between IgAN patients and healthy controls was observed.Furthermore,no association was found between these SNPs in CFB gene and clinical manifestation,pathological features and long term renal outcome of IgAN.Conclusion Association between rs117314762 in CFB gene and IgAN susceptibility suggests that there may be functional variants in CFB gene or its linked genetic region,which needs further exploration.

Objective To explore the rule of energy distribution on the interfaces between lamellar materials,especially the dependence upon the radiating directions for a microwave(MW) radiation and to get some experimental evidences for further research of the shielding and protective mechanism of biological effects of MW.Methods Some MW shielding lamellar materials elaborately chosen,including fiber & metal wires intertexture,MW exposure suit materials by chemical treatment,nano-carbon coated metal sheets and fresh pigskin treated as biological tissue material,were exposed to the defined frequency(9.3 GHz) MW field and the characteristics of MW interfacial reactions upon the materials were detected by a micro-spectrometer.Results The fiber & insulated metal wires intertexture did not possess obvious MW-shielding function.The MW exposure suit materials by chemical treatment were strong reflecting type MW-shielding materials.The nano-carbon coated metal sheets had a "transparent window" for a rather wide range of MW incidence angles and so were used as MW secret materials.As biological tissue material,the fresh pigskin treated was identified as a kind of complex MW absorbing and reflecting material.Otherwise,the interaction between MW and biological material interfaces might vary regularly as the change in water-content occurred by the MW heating effect.Conclusion Although all the kinds of experimental samples exhibited the coherence with the reflection law to MW sheaf,there was plenty of significant diversity in detail nearby the MW reflecting region.The experimental evidence might be of characteristic classification for interaction between MW directional radiation and different material interfaces.Otherwise,as skin tissues absorb microwave rather sharply in little incident angles,this part of radiations should be considered more in the protective mechanism of MW.

Objective: To investigate the influence of social comparison and social support on negative physical self of female from adolescents to young adulthood. Methods: 980 female students aged from 12 to 22 completed NPSS-F (negative physical self scale-fatness), MSPSS (multidimensional scale of perceived social support) and PACS (physical appearance comparison scale). Their body mass index (BMI) was also calculated by weight and height of the subjects. Results: High school students had higher score in Fatness dimension than middle school students (13.5?9.3/11.0?9.0,P

Objective:To analyze differential diagnosis and imaging feature of ultrasonography and MRI for adrenal pheochromocytoma.Methods: The manifestations of the preoperative ultrasound and MRI of the 37 patient with adrenal pheochromocytoma who once were confirmed by pathology were analyzed by the retrospective analysis. The result of pathology was used as standard to analyze the accuracy rate and clinical feature of the two detection methods in the diagnosis of adrenal pheochromocytoma.Results: The results of pathological diagnosis for the 37 cases showed that 35 cases were benign and 2 cases were malignant. After the results of preoperative ultrasound was tested by using pathology, the tested results of 37 cases showed 32 cases were adrenal pheochromocytoma, 2 cases were adrenocortical adenocarcinoma and 3 cases were adrenal adenoma. As these results, the accuracy rate of preoperative ultrasound was 86.49%. And after the results of preoperative MRI was tested by using pathology, the tested results of 37 cases showed that 34 cases were adrenal pheochromocytoma, 2 cases were adrenocortical adenocarcinoma and 1 case was adrenal adenoma. And its accuracy rate was 91.89%. Therefore, if patients were diagnosed with adrenal pheochromocytoma by using preoperative imaging detection, they should be considered to receive further diagnosis so as to distinguish adrenal pheochromocytoma with adrenal adenoma, adrenocortical adenocarcinoma, metastatic tumor and lipomatous. Conclusion: Both of ultrasound and MRI can accurately achieve location, diagnosis of qualitative identification for adrenal pheochromocytoma, and the clinical feature and imaging feature which combined the two detections can increase the detectable rate and accuracy rate for adrenal pheochromocytoma.
