Objective To explore the effect of Jianbu-Huqian ointment combined with proximal femoral nail antirotation for the elderly patients with intertrochanteric fracture of femur with osteoporosis. Methods A total of 85 elderly patients with intertrochanteric fracture of femur with osteoporosis were randomly divided into the control group (40 patients) and the observation group (45 patients. Both groups of patients were treated with proximal femoral nail antirotation, and the observation group was added with Jianbu-Huqian ointment. The pain, fracture healing, joint function, bone mineral density and complications were compared between the two groups. Results The VAS pain score at 1st week (6.2 ± 1.6 vs. 7.9 ± 1.6; t=3.683, P<0.05), 3rd week (3.1 ± 1.1 vs. 5.4 ± 1.4; t=4.239, P<0.05) and 7th week (2.3 ± 0.9 vs. 4.0 ± 1.3; t=3.571, P<0.05) after operation of the observation group were significantly lower than those of the control group. The occurrence time (42.4 ± 5.9 d vs. 49.2 ± 6.2 d; t=4.139, P<0.05), walking time (6.9 ± 1.1 weeks vs. 8.7 ± 1.2 weeks;t=3.695, P<0.05), fracture healing time (13.9 ± 2.2 weeks vs. 16.2 ± 3.1 weeks, t=3.473, P<0.05) of the observation group were significantly lower than those of the control group. Harris hip score (89.8 ± 7.21 vs. 81.4 ± 5.93; t=3.728, P<0.05) in the observation group was significantly higher than that in the control group. The bone density of the femur (0.782 ± 0.142 g/cm2 vs. 0.691 ± 0.135 g/cm2; t=3.759, P<0.05) and the area of ward (0.628 ± 0.071 g/cm2 vs. 0.513 ± 0.059 g/cm2; t=4.386, P<0.05) of the observation group were significantly lower than those of the control group. The incidence of postoperative complications in the observation group was 15.0%(6/40), and the control group was 37.8% (17/45). The difference was statistically significant (χ2=5.567, P<0.05). Conclusions The Jianbu-Huqian ointment combined with proximal femoral nail antirotation could reduce the pain, promote fracture healing, and prevent the occurrence of postoperative complications for the elderly patients with intertrochanteric fracture of femur with osteoporosis.

Objective To determine whether relative abundance of epidermal growth factor receptor (EGFR) mutations in plasma predicts clinical response to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in patients with advanced lung adenocarcinoma. Methods In this prospective study, adult patients with advanced lung adenocarcinoma were enrolled in our hospital from 1 April 2016 to 1 January 2017. EGFR mutations in tumor tissues were detected by ADx-amplification refractory mutation system (ADx-ARMS). EGFR mutations of plasma free tumor DNA were detected by ADx-ARMS and ADx-super amplification refractory mutation system (ADx-SuperARMS) at the same time. Patients with EGFR-mutant in tumor tissues and receiving EGFR-TKIs were finally enrolled. Plasma mutation-positive patients with both methods were high abundance group.Patients with positive mutations by ADx-SuperARMS but negative by ADx-ARMS were medium abundance group. Mutation-negative patients with both methods were recognized as low abundance group. The correlation between EGFR mutation abundance and clinical response to EGFR-TKIs were analyzed. Results Among 71 patients enrolled, 42 harbored EGFR mutations in plasma were detected by ADx-ARMS, while 53 were found by ADx-SuperARMS.There were 42 patients in high abundance group, 11 in medium group while the other 18 in low group. The objective response rates (ORRs) were 69.0%,7/11 and 10/18 in high, medium and low groups, respectively. The difference was significant between high and low abundances groups (P=0.006). Median progression-free survival (PFS) in high,medium and low groups were 11.0, 8.5 and 9.0 monthes, respectively (P<0.001). In patients with tumor 19-Del, the ORRs were 70.4%,5/7 and 6/11 in high,medium and low abundance groups, respectively. The median PFS of high abundance group was significantly longer than the other two groups (12.0 monthes vs 9.0, 9.0 monthes). As to subjects with L858R mutation, the ORRs were 10/15,2/4 and 3/6,respectively, with median PFS 9.6, 5.5 and 9.5 monthes. Conclusions The relative abundance of EGFR mutations in plasma predicts clinical response to EGFR-TKIs in patients with advanced lung adenocarcinoma. The higher the mutation abundance is, the better the efficacy of EGFR-TKIs is.
