Objective To investigate the impacts of clinical features, blood and biochemical parameters on survival of patients with pancreatic cancer. Methods Two hundred and four patients with pathologically performed pancreatic cancer were retrospectively analyzed. All patients were followed-up by means of phone. Results The survival rate of 204 patients with pancreatic cancer was 32.8% at 1-year, 13.7% at 3-year and 2.9% at 5-year, with medium survival time of 6.4 months. Univariate examination showed that the long survival time was found in patients with radical or palliate operation in comparison with those without (P<0.01). The factors that impacted on the survival times were high tumor marker, .high serum creatinine, high white blood cells, low hemoglobin and low albumin (P<0.01). Whereas the patients with high levels of ALT and AST had long survival time (P(0.05). COX regression analysis revealed that those with advanced stage, low albumin and high creatinine had short survival time(P<0.05). Conclusions Surgery, tumor stage, tumor marker, hemoglobin, white blood cell, albumin and creatinine are independent prognostic factors.

Aim To investigate whether melatonin ( MT) can alleviate endoplasmic reticulum( ER) stress at an early stage of bleomycin( BLM)-induced lung fi-brosis in mice. Methods Adult healthy male ICR mice were divided randomly into control group, MT group, BLM group and MT + BLM group. In MT group, mice had saline treatment 30 minutes after hav-ing the intraperitoneal injection of MT (10 mg·kg-1 ) and had been intraperitoneally injected with MT once in the following every 24 hours. In BLM group, mice were intratracheally injected with a single dose of BLM (5 mg·kg-1). In MT+BLM group, mice had been intraperitoneally injected with BLM 30 minutes after having MT and had been injected with MT once in the following every 24 hours. In control group, mice re-ceived the same level of saline treatment in the same manner. All mice were dissected for collecting the tis-sue of lungs at different time points (24h, 72h) after BLM treatment. Inflammatory cell infiltration of lungs was determined by HE staining. The level of ER stress related proteins ( GRP78 , p-eIF2α, p-IRE1α) in lungs was determined using Western blot. The distribu-tion of ER stress related proteins ( GRP78 , p-IRE1α, ATF6α, p-PERK) in lungs was detected by immuno-histochemistry. Results The model of BLM-induced acute inflammation of lung fibrosis in mice had been successfully constructed. After BLM treatment, lung weight, lung weight ratio and inflammatory cell infiltra-tion were significantly increased with a significant cor-relation between time and effectiveness. After MT treatment, lung weight, lung weight ratio and inflam-matory cell infiltration were significantly reduced. The results of Western blot showed that MT pretreatment not only prevented the increase of BLM-induced GRP78 protein significantly, but also restrained the phosphorylation of eIF2α and IRE1α in mouse lungs. Immunohistochemistry also showed that MT pretreat-ment reduced the expression of GRP78 , p-IRE1α, ATF6α and p-PERK. Conclusion MT alleviates ER stress effectively at an early stage of BLM-induced lung fibrosis in mice.

Background and purpose:Single drug of docetaxel and pemetrexed as second line treatment is standard treatment of advanced non-small cell lung cancer (NSCLC). Whether combined with platinum can increase the response and survival is still not elucidated. This study was designed to investigate the treatment response, overall survival (OS) and the safety of combined with oxaliplatin or cisplatin regimens as second line in treating NSCLC patients. Methods:Advanced NSCLC inpatients, failure of cisplatin or carboplatin in initial treatment, were divided into three groups at random in 3∶2∶1 rate. Control group:who received docetaxel, 75 mg/m2 (for all patients), d1 or pemetrexed 500 mg/m2 (for non-squamous carcinoma);Cisplatin group:who received cisplatin 25 mg/m2, d1-3 and docetaxel/pemetrexed; Oxaliplatin group: who received oxaliplatin 130 mg/m2 d1 and docetaxel/pemetrexed. Every 3 weeks were repeated as one cycle. The side effect was assessed every cycle and treatment efifcacy was investigated every two cycles. Follow-up examination was taken every 3 months after treatment. Results:There were no differences in treatment response, progress free survival (PFS), OS and toxicity among the three groups (P>0.05). Old patients (≥60 years) had a better PFS than that of patients less than 60 years (HR=0.56, 95%CI:0.35-0.90, P=0.015). Patients with performance score 0-1 had a better PFS and OS (HR=1.52, 95%CI:1.01-2.30, P=0.048;HR=1.90, 95%CI:1.17-3.09, P=0.009). Treatment response had relation to PFS and OS (HR=2.93, 95%CI:2.01-4.26, P=0.000;HR=2.03, 95%CI:1.37-3.01, P=0.000). Patients with anemia after treatment tended to have a worse PFS and OS (HR=1.59, 95%CI:0.97-2.61, P=0.066;HR=1.60, 95%CI:0.94-2.75, P=0.085). Patients with thrombocytopenia after therapy had a worse OS (HR=2.97, 95%CI:1.01-8.78, P=0.049). Patients with neural toxicity after chemotherapy tended to have a worse PFS (HR=3.36, 95%CI:0.92-12.25, P=0.066). Patients received post treatment after second line therapy had a better OS (HR=0.36, 95%CI:0.22-0.61, P=0.000). Conclusion:Combined with oxaliplatin or cisplatin as second line treatment can’t improve the response and survival in NSCLC patient. Treatment response and PS are prognostic factors to NSCLC patients’ PFS and OS. Patients with treatment related anemia might have a worse survival. Post therapy after failure to second line chemotherapy can prolong the survival.

Purpose To assess the clinical application of non-contrast-enhanced MR angiography (NCE-MRA) using flow sensitive dephasing (FSD) prepared steady-state free precession (SSFP) for displaying hand arteries of patients with rheumatoid arthritis. Materials and Methods Twenty-two patients with rheumatoid arthritis were recruited in this study. All the patients undertook hand NCE-MRA and three-dimensional dynamic CE-MRA on a 1.5T MR scanner. The informed consent was obtained from each subject. Image quality was assessed independently by two experienced radiologists at three arterial segments (wrist arteries, palm arteries, andfinger arteries) with a four-point scale. Signal to noise ratio (SNR), contrast to noise ratio (CNR), and vessel sharpness were evaluated by a magnetic resonance physicist. The results and image quality were statistically compared between the two MRA techniques.Results Twenty-two patients of 24 hands successfully underwent NCE-MRA and CE-MRA scan. Among 72 vascular segments, 69 segments of NCE-MRA were diagnostic, which was higher than that of CE-MRA (96% vs 83%,P<0.05). Otherwise, the image quality, SNR, CNR and vessel sharpness of NCE-MRA were all superior to those of CE-MRA (P<0.05).Conclusion NCE-MRA using FSD-prepared SSFP allows clear depiction of the hand arterial tree, and the image quality is superior to that of dynamic CE-MRA. It is a potential tool for evaluating the disease of hand arteries.
