This study assessed the clinical application of transvaginal three-dimensional ultrasound (3D TVUS) in the diagnosis of congenital uterine malformation. A retrospective study was performed on 62 patients with congenital uterine malformation confirmed hysteroscopically and/or laparoscopically. The patients were subjected to transvaginal two-dimensional ultrasound (2D TVUS) and 3D TVUS. The accuracy rate was compared between the two methods. The accuracy rate of 3D TVUS was (98.38%, 61/62), higher than that of 2D TVUS (80.65%, 50/62). 3D TVUS coronal plane imaging could demonstrate the internal shape of the endometrial cavity and the external contour of the uterine fundus. It allowed accurate measurement on the coronary plane, and could three-dimensionally show the image of cervical tube, thereby providing information for the diagnosis of some complex uterine malformation. 3D TVUS imaging can obtain comprehensive information of the uterus malformation, and it is superior to 2D TVUS for the diagnosis of congenital uterine malformations, especially complex uterine anomaly.

Objective To assess the inlfuence of depth on liver stiffness measurement with real-time shear wave elastography (SWE) and determine the optimal depth for SWE in liver. Methods SWE of liver was performed on 89 healthy volunteers between May 2012 and November 2012. The depths of each liver were varied from 0 cm to 7 cm (from the liver capsule) in 1 cm increment and there were 8 depth groups in total. Then the elastic modulus of liver in each depth group were measured three times by SWE. The body mass index (BMI) and the distance from body surface to liver capsule were documented. The success rates and the mean elastic modulus of each group were calculated. Results The success rates of 0-7 cm were 0, 98.9%(88/89), 98.9%(88/89), 98.9%(88/89), 71.9%(64/89), 24.7%(22/89), 3.4%(3/89) and 0, respectively. The success rates were highest in 1 cm, 2 cm and 3 cm groups but signiifcant decreased with the increasement of depths in 4 cm, 5 cm and 6 cm groups ( 3 cm vs 4 cm, χ2=25.94, P<0.001; 4 cm vs 5 cm, χ2=39.68, P<0.001;5 cm vs 6 cm,χ2=16.79, P<0.001). The mean elastic modulus of 1 cm, 2 cm, 3 cm, 4 cm and 5 cm groups were (4.77±0.99), (4.68±0.99), (4.76±0.95), (5.19±1.10) and (5.41±0.95) kPa, respectively. The mean elastic modulus of 4 cm and 5 cm groups were signiifcant higher than those of 1 cm, 2 cm, 3 cm groups (4 cm vs 1 cm, t=-2.85, P=0.005;4 cm vs 2 cm, t=-3.49, P=0.001;4 cm vs 3 cm, t=-2.76, P=0.006;5 cm vs 1 cm, t=-3.13, P=0.002;5 cm vs 2 cm, t=-3.66, P=0.000;5 cm vs 3 cm, t=-3.05, P=0.003). In the group of 4 cm, the BMI and the distance from body surface to liver capsule of the volunteers performed successfully and unsuccessfully were (20.70±2.87), (22.07±2.42) kg/m2 and (1.45±0.25 ), (1.60±0.29) cm, respectively. In the group of 5 cm, the BMI and the distance from body surface to liver capsule of the volunteers performed successfully and unsuccessfully were (19.82±2.76), (21.49±2.72) kg/m2 and (1.35±0.21), (1.54±0.26) cm respectively. The BMI had no signiifcant difference between the successful and unsuccessful groups (t=-2.83, P=0.108 for 4 cm;t=0.77, P=0.709 for 5 cm), but the distance from body surface to liver capsule was signiifcantly different (t=26.51, P=0.012 for 4 cm;t=79.57, P=0.004 for 5 cm). Conclusions The success rates and elastic modulus were different at different depths. SWE should be performed at the depths of 1-3 cm from the liver capsule.

?AIM:To observe the values and changing rules of angle Kappa in corneal refractive surgery under light and dark conditions.?METHODS:Two hundred and thirty-four eyes of 118 patients for corneal refractive surgery were enrolled for this study.Pupil diameters and angle Kappa values under light and dark conditions were measured by Keratron Scout corneal topography.?RESULTS: There were significant differences in pupil diameters between light and dark conditions (P<0.01). More angle Kappa of both eyes distributed in the superior nasal quadrant under light conditions, and more angle Kappa distributed in the superior temporal quadrant under dark conditions.The differences of horizontal and vertical offsets of angle Kappa under two conditions were statistically significant (P<0.01).?CONCLUSION: The changes of pupil diameters in light and dark conditions could affect angle Kappa and then affect the accuracy of corneal refractive surgery centered on angle Kappa.

OBJECTIVETo systematically review the effectiveness of minimally invasive total hip arthroplasty (MIS-THA) versus traditional total hip arthroplasty (THA) in patients with hip diseases.

METHODSThrough a method of combining Free words and keywords,we searched databases including PubMed,The Cochrane Library, EMbase,Web of Science, CBM , CNKI and Wanfang Data for randomized controlled trials (RCTs) on the comparison between MIS-THA and THA for hip disease from inception to June, 2014. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies according to the "bias risk assessment" tool recommended by Cochrane Handbook 5.0 for Systematic Reviews. Then, meta-analysis was performed using RevMan 5.3 software.

RESULTSThirteen RCTs involving 1 213 cases of surgeries and total 1 284 hips (MIS-THA: n = 631; THA: n = 653) were identified. The results of meta-analysis showed that statistically significant differences were found in Harris hip score on the 3rd month after operation [MD = 8.37, 95% CI (6.02,10.72)], Hematocrit [MD = 0.02, 95% CI (0.01, 0.03)] and Hemoglobin [MD = 0.50, 95% CI (0.16, 0.85)] at the 48th hour after operation, changed value of femoral offset [MD = 0.30, 95% CI (0.04, 0.56)] between two groups. In the change value of femoral offset, THA was better than MIS-THA; There were no statistically significant differences between two groups in Harris hip score at 1st year after operation [MD = 3.26, 95% CI (-3.25, 9.76)], WOMAC score [MD = -0.53, 95% CI (-3.67, 2.60)] and Oxford score [MD = 1.34, 95% CI (-3.46, 6.13)] at the 6th week after operation, Hematocrit at the 8th hour after operation [MD = -0.01, 95% CI (-0.02, 0.00)], the incidence of hip varus [RR = 0.82, 95% CI (0.45,1.52)] and dislocation [RR = 1.40, 95% CI (0.48, 4.12)].

CONCLUSIONTHA brings less trauma, less hemorrhage and better early clinical outcome compared with MIS-THA, but the difference of the complication rates between the two groups is similar.

AIM:To investigate the effect of SCH900776, an inhibitor of checkpoint kinase 1(CHK1), on the proliferation and migration abilities of human glioma U 251 cells.METHODS:The cell viability was detected by MTT assay,and cell proliferation was determined by cell colony formation assay.Cell cycle distribution was analyzed by flow cy-tometry.Wound healing assay was used to determine the cell migration ability.The protein levels were determined by Western blot.RESULTS: SCH900776 inhibited the growth of U251 cells in a dose-dependent manner(P <0.05). SCH900776 treatment substantially induced U251 cell cycle arrest in S and G 2/M phases by decreasing the level of cell di-vision cycle protein 2(Cdc2)and p-Cdc2.Moreover,SCH900776 inhibited the cell migration.Western blot results indi-cated that SCH900776 increased the phosphorylation level of p 38 MAPK and inhibited the activation of Akt.CONCLU-SION:SCH900776 inhibits the proliferation and migration abilities in human U 251 cells by promoting the phosphorylation of p38 MAPK and suppressing the activation of Akt.
