Objective: The aim of this study was to explore change and significance of serum carcino-embryonic antigen (CEA) before and after gefitinib therapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods: Forty patients with advanced NSCLCs in III~IV stages were selected as study objects given gefitinib therapy combined with routine local radiotherapy until tumor progression or intolerable toxicity. After treatment, all patients were divided into control and non-control groups according to the results of evaluation based on RECIST 1.1 (Response Evaluation Criteria in Solid Tumors in 2009). Peripheral fasting blood from all patients was collected in the early morning and serum CEA was assessed by electro-chemiluminescence immunoassay (ECLIA) before and after treatment. Before treatment, patients were divided into high CEA group (CEA level > 50 ng/mL) and low CEA group (CEA level ${\leq}$ 50 ng/mL). Adverse reactions were noted and progression-free survival (PFS) in both groups was recorded after long-term follow-up that ended in December, 2012. Results: There was no difference between control and non-control groups in CEA level before treatment (P>0.05), whereas serum CEA decreased more markedly lower in the control group after treatment (P<0.01). All patients were divided into high CEA group (26) and low CEA group (14) according to serum CEA level. There was no statistically significant difference between two groups in adverse reactions (P>0.05) but the rate in former group was lower. Additionally, survival rates at 9 and 12 months in high CEA group were clearly higher than in the low CEA group (P<0.01). Conclusions: Serum CEA level can serve as a biochemical index to evaluate the prognosis with gefitinib treatment for NSCLC.

Introduction: Squamous cell carcinoma of esophagus (ESCC) is one of the most common cancers in China. Preserved vegetables are processed foods and consumed in high amounts in the high risk areas for ESCC. This study aimed to investigate the relationships of preserved vegetable consumption with ESCC and precancer lesions. Methods: Cases from Yanting cancer hospital with pathological diagnosis of primary cancer, along with controls and individuals diagnosed with precancer lesions by endoscopy with iodine staining were interviewed. Trained staff collected data on dietary habits 1 year before the interview. An unconditional logistic regression model was used to estimate odds ratios of preserved vegetable consumption for precancer lesions and cancer. Results: Adjusting for potential confounders, intake of preserved vegetables (OR=2.92, 95%CI 1.32~6.47) and longer intake period (OR=5.78, 95%CI 2.26~14.80) were associated with higher risk of ESCC. Compared with lowest intake frequency, the highest was associated with a 3.0-fold risk for precancer lesions and 3.59-fold risk for ESCC (both p<0.05). Conclusion: Consumption of preserved vegetables is a risk factor for esophageal lesions in high risk areas. The carcinogenicity of preserved vegetables needs investigation in further studies and the public health strategies for reducing the consumption might be initiated in high risk areas.

Antimicrobial Aflatoxins from the Marine-Derived Fungus Aspergillus flavus 092008

A new aflatoxin, aflatoxin B2b (1), together with six known compounds, were isolated from the marine-derived fungus Aspergillus flavus 092008 endogenous with the mangrove plant Hibiscus tiliaceus (Malvaceae). The structure of 1 was determined by the spectroscopic and chemical methods. Compound 1 exhibited a moderate antimicrobial activity against Escherichia coli, Bacillus subtilis and Enterobacter aerogenes, with MIC values of 22.5, 1.7 and 1.1 μM, respectively. Compound 1 also showed a weak cytotoxicity against A549, K562 and L-02 cell lines, with IC50 values of 8.1, 2.0 and 4.2 μM, respectively. The results showed that hydration and hydrogenation of Δ8-double bond significantly reduces the cytotoxicity of aflatoxins, while the esterification at C-8 increases the cytotoxicity.
