ABSTRACT
Objective We aim to evaluate and discuss the feasibility of Hyaline imaging of three-dimension sonography in observation of paravaginal support structure in normal nonporous women.Methods Total of 45 normal infertile women were chosen.Three-dimensional volume datasets were collected at rest by transperineal ultrasound.The three-dimensional Hyaline images were acquired off-line.We observed the morphologic features of paravaginal support structure on the axial plane in middle vagina and measured the anteroposterior and lateral horizontal distances between bilateral paravaginal support structure and ureter.The consistency between two sonographers were analyzed by intraclass correlation coefficient (ICC).Results In three-dimensional Hyaline imaging sonogram,paravaginal support structure was appeared as typically tenting-like shaped.The anteroposterior distances between paravaginal support structure and center of ureter were listed as followed:left (-0.31 ± 1.29) mm,right (0.47 ± O.99) mm.While the lateral horizontal distances were left (12.67 ± 6.70) mm,right (13.01 ± 5.75) mm.There were no statistical differences between bilateral both anteroposterior and lateral horizontal distances.The consistency between two sonographers for distinguishing paravaginal support structure on the middle-vaginal plane and measuring distances between paravaginal support structure and center of ureter was remarkably high (ICC is 0.87 and 0.82).Conclusions Hyaline imaging technology of three-dimensional pelvic floor sonography could be used to observe paravaginal support structure in women.The normal paravaginal support structure is typically showed as bilateral symmetrical tenting-like structure,which is on the same level as the center of ureter.It provides normal anatomic radiological evidence and helps study defect of paravaginal support structure caused by pregnancy or delivery.
ABSTRACT
Objective:This study aimed to investigate the expressions of EZH2 and Ki-67 in the salivary adenoid cystic carcino-ma (SACC) of humans and their correlation. Methods:A total of 42 cases of SACC tumor tissues and 5 cases of normal tissues were considered to determine the expressions of EZH2 and Ki-67 by immunohistochemistry. The relationship and correlation of such expres-sions with the clinicopathological characteristics were also analyzed. Results:The expression of EZH2 was notably higher in SACC than in normal tissues (P<0.05). EZH2 expression was detected in 66.67%(28/42) of the tumor tissues. This expression was correlated with pathological grade and clinical stage. By contrast, EZH2 expression did not correlate with gender, age, and localization. EZH2 was not expressed in normal tissues. The incidence of EZH2 expression in the Ki-67 positive group was 75.76%(25/33) and the incidence in the Ki-67 negative group was 33.33%(3/9). The difference between the two groups was statistically significant (P<0.05). Conclu-sion:The increased expression of EZH2 in SACC was related to tumor proliferation. EZH2 may participate in tumor cell proliferation via cell cycle management.
ABSTRACT
ObjectiveTo investigate the clinical value of G5 Percussive Mobilizer in respiratory failure.Methods76 patients with respiratory failure were randomly divided into the treatment group (38 cases) and control group (38 cases). The treatment group were treated with G5 Percussive Mobilizer made in America,and the control group were treated with knock expectoration. The daily sputum volume, clinical symptoms, thoracic signs and arterial blood gas analysis changes were observed. ResultsThe daily sputum volume,clinical symptoms,thoracic signs and arterial blood gas analysis changes of the treatment group (31 cases effective,81.6% ) has significant difference compared with the control group (23 cases effective ,60.5% ) ( P < 0. 05 ). ConclusionG5 Percussive Mobilizer can eliminate the bronchial secretion rapidly and effectively,and it can help improve the ventilation and oxygenation function. It is safe, effective and easy to practice in bronchial purification treatment.
