Polymorphisms in AMPD1 34C>T and ATIC T675C predict responsiveness. The absence of TYMS 1494 del6 and FPGS rs10106 and presence of MTHFR C677T predict adverse events in RA patients treated with MTX. Moreover, variations of the associations were found between Caucasians and non-Caucasians.

This meta-analysis suggests that LDV-SOF based therapy is a safe and effective treatment for patients with GT 1 HCV. The addition of RBV to LDV-SOF may increase toxicity without achieving improved efficacy. However, due to the relatively small sample sizes and moderate risk of bias of included studies, large-scale and high-quality clinical research is still needed to confirm the results.

SUs have a small effect on lipids, although they may statistically increase the level of FFA and TG, and decrease LDL-C and HDL-C.

The aim of our study is to investigate the feasibility of reconstructing the carotid artery using expanded polytetraflouroethylene (ePTFE) in patients with recurrent head and neck carcinoma involving the carotid artery. Ten patients, who had recurrent head and neck carcinoma involving the carotid artery, received carotid artery resection and reconstruction with ePTFE, tissue defects were repaired by pectoralis major myocutaneous flap. Results show that eight patients did not present any vascular and neurologic complications. One patient presented slight hemiparesis, another patient developed wound infection and pharyngocutaneous fistula. The mean follow-up period was 33.1 ± 16.0 months. The 2-year survival rate was 50% (5/10), and there was one patient who survived for 60 months without locoreginal recurrence or distant metastasis. En bloc resection of tumor and involved carotid-associated ePTFE reconstruction provide effective improvement in the locoregional control of the recurrent head and neck carcinoma. The pedicle pectoralis major myocutaneous flap can provide not only wound bed with affluent blood supply for the vascular grafts, but also reparation of skin or the tissue defects of oropharynx and hypopharynx.

Abstract-the "Three-River Headwaters" region (TRHR) rangeland ecosystem is extremely sensitive and fragile, and in recent years has undergone continuous degradation. The vast area and severe nature conditions inhibit data acquisition and field experiments, resulting in different understandings about the spatial characteristics and dynamics of rangeland degradation in the region. Therefore, reliable monitoring method of rangeland degradation is urgently needed for the rangeland protection and management. In this paper, a novel rangeland degradation monitoring scheme based on Local NPP Scaling (LNS) was suggested;A suitable partition program of rangeland productivity unit was set up by using Analytical Hierarchy Process (
