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.

Aim To investigate the effects of pyrrolidine dithiocarbamate (PDTC) on D-galactosamine/lipopolysaccharides (GalN/LPS)-induced acute apoptotic liver injury and its mechanism.Methods All mice were randomly divided into four groups.Mice in GalN/LPS group were co-injected with GalN (600 mg·kg~(-1),ip) and LPS (20 μg·kg~(-1), ip). Mice in PDTC+GalN/LPS group were injected with two doses of PDTC,one (100 mg·kg~(-1), ip) at 24 h before LPS and the other at 2 h before LPS (20 μg·kg~(-1), ip).Mice in control groups were treated with PDTC (100 mg·kg~(-1), ip) or saline. Ten mice in each group were observed for animal survival within 72 h after LPS treatment. Six mice in each group were sacrificed 1.5 h after LPS for collecting blood and isolating livers. The expression of hepatic TNF-α mRNA was determined by reverse transcription and polymerase chain reaction (RT-PCR). Hepatic nuclear factor-κB (NF-κB) binding activity was measured with electrophoretic mobility shift assay (EMSA).Twelve mice in each group were sacrificed 8 h after LPS treatment. Serum was collected for measurement of alanine aminotransferase (ALT) and hepatocellular apoptosis and histological examination.Results Co-injection of GalN and LPS markedly increased serum ALT activity. Histopathological examination of liver sections revealed that GalN/LPS induced hepatic congestion, necrosis and massive macrophages infiltration, and increased the number of TUNEL-positive cells in mouse liver.GalN/LPS treatments, led to 90% mortality within 72 h with severe congestion and necrosis in the liver of all the dead mice. PDTC pretreatment significantly inhibited GalN/LPS-induced hepatic NF-κB activation and TNF-α expression. In contrast, PDTC aggravated GalN/LPS-triggered hepatocellular apoptosis, increased serum ALT activity, exacerbated hepatic hemorrhage and necrosis, and accelerated death.Conclusion PDTC aggravates GalN/LPS-induced acute apoptotic liver injury via inhibiting NF-κB-mediated anti-apoptotic effects.
