The cytotoxic agents pemetrexed and docetaxel and the epidermal growth factor receptor (EGFR)tyrosine kinase inhibitors(TKIs)erlotinib and gefitinib are standard second-line therapies for non-small cell lung cancer. For patients without the EGFR mutation,more and more evidence has suggested the superiority of chemotherapy over targeted therapy. Adding targeted agents to standard second-line treatment is an trend of exploration,but without promising results nowadays. Crizotinib,targeting at anaplastic lymphoma kinase,has been shown excellent efficacy for second-line therapy in non-small cell lung cancer.

Objective To investigate the effects of swimming exercise training on left ventricular (LV)remodeling and its possible mechanism in spontaneous hypertensive rats (SHR).Methods Twenty eightweek-old male SHRs were divided into SHR control (SC) group and SHR exercise training (ST) group,with 10 rats in each group.Ten eight-week-old male Wistar rats were used as normal control (WC) group.The ST group was subject to 60-min moderate swimming exercise without loading once daily,6 times a week,for a total of 12 weeks; while the SC and WC group had no special intervention.The blood pressure was examined once weekly.After 12 weeks,the norepinephrine (NE)and serum angiotonin Ⅱ (ANG Ⅱ) levels were determined by ELISA.The LV hypertrophy was assessed by analysing the ratio of LV weights to body weights (LVW/BW) and cardiomyocyte diameter.The collagen deposited in LV was detected by sirius red staining.The expressions of tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) in LV were determined by semi-quantitative real time-polymerase chain reaction (RT-PCR) and Western blotting.Results After 12 weeks,the blood pressure,serum NE and ANG Ⅱ levels,LVW/BW ratio,cardiomyocyte diameter and collagen volume fraction (CVF) increased significantly in SC group compared with WC group; while those in ST group decreased significantly.In addition,in ST group the mRNA and protein expressions of TNF-α,IL-6,IL-1 βand TGF-β1 also decreased significantly.Conclusions The swimming exercise could reduce the blood pressure of SHR and improve LV remodeling.This effect was mediated not only by improving the hemodynamics,but also by decreasing sympathetic nerve and renin-angiotensin system (RAS) activities,decreasing the gene expressions of cytokines.The swimming exercise may be an effective strategy for improving LV remodeling in hypertension.

Objective To optimize the parameters for the diffusion tensor imaging (DTI)of the ulnar nerve in elbow.Methods 5 groups of DTI sequences with different b values and numbers of diffusion gradient directions (NDGDs)were used to collect ulnar nerve images from 13 volunteers,and then the diffusion tensor tractography (DTT)was established.The fractional anisotropy (FA),apparent diffusion coefficient (ADC),length of ulnar nerve fiber and DTI image quality were compared under different imaging parameters. Results DTI results for 18 normal ulnar nerves were included in the study.Under different imaging conditions,FAs showed no significant differences.With constant NDGDs,increasing b value decreased both image quality and ADCs of the ulnar nerve.NDGDs had no significant effects on ADCs or image quality.When b=1 000 s/mm2 and NDGDs=20,the length of the ulnar nerve fiber was the longest and DTT had the best subjective scoring in image quality.Conclusion b=1 000 s/mm2 and NDGDs=20 is recommended for DTI of elbow ulnar nerve,so as to obtain high image quality and stable observing targets.

Objective To evaluate the curative effect and toxicities of platinum-based double regimens for patients aged ≥ 65 with advanced non-small-cell lung cancer (NSCLC) and identify the prognosis factors. Methods 70 patients aged ≥65 with staged ⅢA-Ⅳ NSCLC, who received platinum-based double regimens as first line treatment, were emrolled.Response rates and toxicities were evaluated.Progression free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Cox regression analysis was used to identify the potential prognosis factors.Results The median chemotherapy cycles was 3.The overall response rate was 41.5 % (22/53), and there was no difference between patients aged <70 and ≥70 (χ2 =1.945, P =0.378).The median PFS and OS were 6.0 months and 12.5 months.The chemotherapyrelated hematologic toxicities were common.Multivariate analysis revealed that performance status, numbers of metastasis, chemotherapy cycles were significant independent predictive factors for OS. Conclusion In elderly advanced NSCLC, platinum-based doublets show inspiring efficacy, but with more adverse events, and could not be all well tolerated. It should be personalized. Patients with poor performance status and multiple organs metastasis are hard to benefit from combined chemotherapy.Three to six cycles of chemotherapy is the optimal duration for patients who could be well tolerated.
