Acta Universitatis Medicinalis Anhui 2014;(9):1305-1309
Objective To investigate the expression of thymosin beta4 ( Tβ4 ) in the liver tissues of children with hepatoblastoma ( HB) , and further study the function of Tβ4 in HB metastasis in vitro. Methods Immunohisto-chemistry (IHC) was used to determine expression of Tβ4, E-cadherin andβ-catenin in liver tissues from 19 chil-dren with HB,and further to analyze its function in metastasis of HB cells. Results The positive rate of Tβ4 ( P<0.01 ) in HB liver tissues was significantly higher than it in the adjacent tissues. The positive rates of Tβ4 and nu-clearβ-catenin in HB with lymphnode metastasis were significantly higher than in HB without lymphnode metastasis ( P <0.01 ) . While expression of E-cadherin in HB with lymphnode metastasis was lower than in HB without lymphnode metastasis ( P<0.01 ) . Scratch-wound assay showed that HepG2 cells with Tβ4 knockdown had signifi-cantly lower metastatic ability (P<0.05). Conclusion Tβ4 plays an important role in HB metastasis, suggesting it is a potential target for HB metastasis.

Objective To discuss anatomic landmarks during retroperitoneoscopic radical nephrectomy. Methods A total of 46 patients underwent retroperitoneoscopic radical nephrectomies from November 2002 to July 2004.The first trocar was introduced at the union of the site 2 cm below the 12 th costal margin with the lateral side of the musculus sacrospinalis.The second trocar was placed at the midpoint of the upper border of the iliac crest,or at the location above and medial to the anterior superior iliac spine.And the third one was inserted at the union of the anterior axillary line with the costal margin.In the first place,the greater psoas muscle was identified as the dorsal marker.Then the diaphragmatic muscle was identified as the posterior marker of the upper pole of the kidney,and the adrenal gland as the medial marker of the upper pole of the kidney,and the peritoneum as the ventral marker.The renal vein lay below and anterior to the renal artery.The right renal vein was routinely sperated right up to the joining site with the inferior vena cava.A linear cutter was used to resect the renal vein and artery respectively. Results The mean operation time was 145 min (range, 60~ 255 min) and the mean intraoperative blood loss was 133 ml (range, 20~1 000 ml). Adrenalectomy was performed in 32 patients (69 6%). A conversion to open surgery was required in 1 patient because anatomic landmarks could not be well seen. The inferior vena cava was wrongly closed off by 1/2 cross-section when using a linear cutter to sever the right renal vein in 1 patient. Peritoneal injuries happened in 4 patients.Follow-up was carried out for 1~20 months (mean,9 months) in all the 46 patients.One patient died of liver metastasis 1 year after the surgery, while the remaining 45 patients survived without recurrence. Conclusions Proper identification of anatomic landmarks is crucial to a successful retroperitoneoscopic nephrectomy.

Objective To investigate the clinical value of a three-dimensional motion analysis system by using the body segmental method for testing the balance of hemiplegic stroke patients.Methods Twenty stroke patients with hemiplegia were measured using the lower extremity Fugl-Meyer motor assessment (FMA-L),the Brunel balance assessment (BBA),the Berg balance sale (BBS) and a 5 m timed up-and-go test (5m-TUGT).The three-dimensional motion analysis system using the body segmental method was applied in three positions-sitting,standing and walking.Spearman's rank correlation coefficient was used to determine the extent of correlation between the values measured by the three-dimensional motion analysis system and the FMA-L,BBA,BBS and 5m-TUGT results.Results Some motion analysis variables (MSAx,MSVx,MSAy,MSVy and SPxy,SP3-D) are recorded in sitting and standing,while the center of gravity (COG) swing in the horizontal plane and some other variables (MSAx,MSVx and SPxy and SP3-D) are measured while walking.Anterior-posterior COG swing had a high negative correlation with the FMA-L,BBA and BBS scores and a high positive correlations with 5m-TUGT times.But except in sitting,MSAz and MSVz were both uncorrelated with FMA-L,BBA or BBS scores or with 5m-TUGT times.COG swing in the horizontal plane in sitting and standing apparently correlates with lower extremity motor function,balance,and walking ability.However,only the X axis swing parameters of the COG while walking correlated with lower extremity motor function,balance or walking ability.Conclusions A three-dimensional motion analysis system using the body segmental method can be used clinically to monitor patients' balance in real time and dynamically in different positions and activities,and it can be used to predict motor function and balance control in hemiplegic stroke patients.
