OBJECTIVETo study which classification model was most suitable for establishing a multi-tumor markers lung cancer prediction model, through established logistic regression model, decision trees model and artificial neural network model.
METHODSRIA analysis, ELISA, spectrophotometry, high-performance liquid chromatography (HPLC) and atomic absorption spectrometry were used to measure the serum CEA, CA125, gastrin, NSE, beta2-MG, Sil-6 receptors, sialic acid, nitric oxide, Cu, Zn, Ca and the pseudo-urine nucleoside of urine samples in lung cancer patients, benign lung disease patients and healthy controls. The lung cancer diagnosis models were established by logistic regression analysis, decision tree analysis and artificial neural network training.
RESULTSThe diagnosis sensitivities of the logistic regression analysis, decision tree analysis and artificial neural network model with 12 tumor markers in lung cancer were 94.00%, 100.00% and 100.00%; the specificity were 100.00%, 98.89% and 100.00%; the total accurate 94.29%, 95.00% and 90.00%, respectively.
CONCLUSIONThe results of three classification models with 12 tumor markers in diagnosis of lung cancer are ideal. Especially the C5.0 decision tree model and the artificial neural network model are more suitable for the prediction and diagnosis of the lung cancer.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

OBJECTIVEThis study was conducted to characterize polybrominated diphenyl ethers (PBDEs) load in human serum of Taiyuan city in 2010.
METHODSA total of 42 blood samples were collected in Taiyuan city, 2010. Solid-phase extraction (SPE)-gas chromatography-negative chemical ionization-mass spectrometry method was used to measure the concentration of brominated diphenyl ethers (BDE)-17, BDE-28, BDE-47, BDE-66, BDE-99, BDE-100, BDE-153, BDE-154, BDE-183 and BDE-209 and ΣPBDEs was calculated.
RESULTSOf the tested serum samples, ΣPBDEs ranged from 2.09 to 66.74 ng/g of lipid weight (lw), the median and mean was 6.32 ng/g lw and 9.84 ng/g lw, respectively. BDE-209 was the main source of ΣPBDEs and its concentration ranged from no detection to 64.99 ng/g lw, the median was 4.11 ng/g lw, accounting for 67.6% of ΣPBDEs. Second source was BDE-153 and its concentration ranged from 0.29 to 4.92 ng/g lw, the median was 0.62 ng/g lw accounting for 10.1% of ΣPBDEs.
CONCLUSIONThe overall load of PBDEs in the serum of local residents was low in 2010.

OBJECTIVETo assess the value of urinary liver-type fatty acid-binding protein (L-FABP) in early assessment of the severity of traumatic brain injury and in predicting the occurrence of acute kidney injury (AKI) following the brain injury.
METHODSSixty-five patients with traumatic brain injury patients were divided into 4 groups according to their Glasgow coma scale (GCS) scores. Blood and urine samples were collected at 2, 6, 12, 24, 48 and 72 h after the injury to detect serum creatinine (SCr) level using biochemical analyzer and urinary L-FABP using enzyme-linked immunosorbent assay (ELISA), with samples from 15 healthy adults as controls. The correlations were analyzed among SCr, urinary L-FABP, GCS score upon admission and AKI occurrence.
RESULTSThe patients with moderate to severe brain injuries showed significantly higher SCr and urinary L-FABP levels than the control group (P<0.05). GCS score of the patients was inversely correlated with the levels of SCr and urinary L-FABP (P<0.05), and the changes were more prominent in urinary L-FABP than in SCr. The incidence of AKI was 21.54% in these patients. In patients with AKI, urinary L-FABP reached the peak level as soon as 6 h after the injury, as compared with 24 to 48 h when peak SCr level occurred.
CONCLUSIONUrinary L-FABP can be used as a marker for early assessment of the severity of traumatic brain injury and for predicting the occurrence of AKI following the injury.
