ABSTRACT
Objective XPll.2/TFE RCC is an independent subtype of renal cell carcinoma, which is rare. The aim of this study is to investigate the CT features of Xp11.2/TFE RCC and improve the accuracy of diagnosis. MethodsCT findings of 30 cases from August 2009 to September 2017 of Xp11.2/TFE RCC from Eastern War Zone General Hospital, including location, density, edge, enhancement degree, lymphatic metastasis and others. They were analyzed respectively and compared with those of ccRCC. ResultsThe differences in CT values between tumors and renal cortex and renal medulla was statistically significant different phases (PP< 0.01). Most of patients with Xp11.2/TFE RCC are younger, about (36.4±17.7) years old. Females are more common, accounting for about 70% compared with ccRCC(50%). CT plan scan showed slightly higher density, about (45.2±8.9)HU vs (34.1±4.4)HU, high calcification rate, about 46.7% % vs 10.0% and CT scan with contrast agent showed gradual enhancement. The difference all were statistically significant(P<0.05). Conclusion XPll.2/ has certain CT characteristics. Combined with CT and clinical manifestation of patients, it is helpful to improve the accuracy of preoperative diagnosis.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of reserving articular capsule and traditional total hip replacement for old patients with unstable femoral neck fractures.</p><p><b>METHODS</b>From January 2010 to January 2015, one hundred and twenty patients with femoral neck fracture were retrospective review. Among them, sixty patients were treated with total hip arthroplasty reserving articular capsule, the others were treated with traditional total hip arthroplasty without reserving articular capsule. The gender of reserving articular capsule group and traditional group were (male/female) 34/26, 31/29 respectively; the age were (73.4±4.4), (72.3±4.1) years old, respectively. All patients were followed up for six months, the operation time, blood loss, length of stay, incidence of postoperative complications, incidence of postoperative hip dislocation and hip Harris score of the two groups were observed.</p><p><b>RESULTS</b>The operative time of the reserving articular capsule group and traditional group were (95.68±6.90), (93.39±7.90) min (>0.05), and the blood loss were (998.78±15.20), (1 000.25±16.80) ml (>0.05). The time for hospital stay were (10.74±2.90), (13.25±2.20) days(<0.05). The Harris scores were 58.53±5.10, 49.38±4.90(<0.05) at 1 month after operation;91.08±7.50, 90.74±7.10(>0.05) at 6 months after operation.</p><p><b>CONCLUSIONS</b>The method of reserving auricular capsule can not increase the operative time and the blood loss. But it has a favorable effect on decreasing the hospital stay, complication, the rate of early dislocation of the hip joint, improving the function of hip joint.</p>
