RIs of SII, PLR, NLR, LMR and MLR of people in central China were established and validated. It will benefit experimental design of the related studies and lead to better standardizations of SII, PLR, NLR, LMR and MLR for their clinical applications.

As well known, signet-ring cell carcinoma (SRCC) is a rare histological subtype of colorectal adenocarcinoma, which has been associated with poor prognosis and resistant to non-surgery therapy compared with common adenocarcinoma. In this study, we assessed the effect of preoperative radiotherapy (PRT) for locally advanced rectal SRCC in a large patient group from the Surveillance, Epidemiology, and End Results program (SEER, 1988–2011) database. SRCC was found in 0.9% (n = 622) rectal cancer (RC) patients in our study. In the PRT setting, SRCC had significantly worse cancer-specific survival than mucinous adenocarcinoma and nonmucinous adenocarcinoma patients (log-rank, P < 0.001). In terms of SRCC, stage III RC patients benefited from PRT (log-rank, P < 0.001) while stage II did not (P = 0.095). The multivariate Cox proportional hazard model showed that PRT was an independent benefit factor in stage III rectal SRCC patients (HR, 0.611; 95% CI, 0.407–0.919; P = 0.018). In conclusion, SRCC was an independent predictor of poor prognosis in stage III RC patients, but not in stage II. In the PRT setting of locally advanced RC, SRCC patients had significantly worse prognosis. PRT was an independent prognostic factor associated with improved survival in stage III rectal SRCC.

BackgroundThis study aimed to investigate the reliability and validity of serum matrix metalloproteinase-3 (MMP-3) levels and articular ultrasound (US) scores in assessing disease activity and therapeutic response in rheumatoid arthritis (RA) patients.MethodsA total of 151 RA patients were enrolled, of whom 22 were treated with certolizumab pegol (Cimzia, CZP). The RA patients were divided into the following four subgroups according to their disease activity score in 28 joints (DAS28): stable, mild activity, moderate activity, and high activity. Forty-three healthy controls were simultaneously studied. The serum MMP-3 levels and 7-joint US (US7) scores of all subjects were determined. The patients who were treated with CZP were subsequently followed for 6 months.ResultsThe serum MMP-3 levels of all the RA patients were significantly higher than those of healthy controls, and those of patients with moderate and severe RA were significantly higher than those of patients with stable RA. The US7 scores of patients with severe RA were significantly higher than those of patients in other groups. Using the DAS28 as a reference standard, the corresponding cutoff value of MMP-3 was 70.5 ng/ml. After CZP treatment, the MMP-3 levels and US7 scores were significantly decreased at week 2, and the mean changes in US7 scores at weeks 12 and 24 were significantly higher in both groups with American College of Rheumatology 50% positive response (ACR50) and ACR 70% positive response (ACR70) than in the negative groups.ConclusionSerum MMP-3 and the US7 scores could both effectively reflect disease activity and therapeutic responses in patients with moderate to severe RA.Trial registration CTR20140405 (RA0044), CTR20140405: A phase 3, Multicenter, Double-blind, Placebo Controlled, Parallel Group, Randomized, 24-Week Study to Evaluate the Safety and Efficacy of Certolizumab Pegol as Additional Medication to Methotrexate in Chinese Subjects With Active Rheumatoid Arthritis Who Have an Incomplete Response to Methotrexate, Registered on 13 June 2014.
