A Practical Predictive Model Based on Ultrasound Imaging and Clinical Indices for Estimation of Response to Neoadjuvant Chemotherapy in Patients with Breast Cancer.

Purpose: Clinical responses of neoadjuvant chemotherapy (NACT) are associated with prognosis in patients with breast cancer. The selection of suitable variables for the prediction of clinical responses remains controversial. Herein, we developed a predictive model based on ultrasound imaging and clinical indices to identify patients most likely to benefit from NACT.

[Operative treatment of old acetabular fractures].

Objective: To explore the operative methods and effects of treatment of old acetabular fractures.

Methods: From October 2001 to October 2007, 26 patients with old acetabular fractures were treated with operation including 21 males and 5 females with an average age of 34 years ranging from 18 to 65 years. On the basis of the three-dimensional computed tomography, all cases were diagnosed and classified according to Letourne-Judet classification, 9 cases were posterior wall fracture, 3 cases were lateropulsition fracture, 7 cases were lateropulsition and posterior wall fracture, 2 cases were posterior column and posterior wall fracture, 2 were T-shape fracture, 3 were dual column fracture.

Analysis of safety and effect of reconstructing anterior and middle columns by single posterior approach in treating lumbar burst fractures.

Objective: To explore the safety and effect of the technique of reconstructing anterior and middle columns by posterior approach in treating lumbar burst fractures.

Methods: From July 2005 to January 2007, 22 cases (18 males and 4 females, aged 28-57 years, 42.7 years on average) of lumbar burst fractures were treated with surgical procedures in our hospital.
