OBJECTIVETo investigate the diagnostic value of serum CEACAM1 in patients with pancreatic cancer.
METHODSFifty patients with pancreatic cancer and 50 with chronic pancreatitis were examine for serum levels of CEACAM1 by enzyme-linked immunosorbent assay (ELISA). The cut-off values and area under curve (AUC) of CEACAM1 was obtained by receiver operating characteristic (ROC) curve. The diagnostic efficiency of the tumor markers for pancreatic cancer was assessed by the fourfold table.
RESULTSThe serum level and positivity rate of CEACAM1 in pancreatic cancer patients were higher than those in chronic pancreatitis patients (P<0.05). Based on the ROC curve, the cut-off values and AUC of CEACAM1 were 13.835 ng/ml and 0.780, respectively (P<0.05). In pancreatic cancer patients, the diagnostic sensitivities of the tumor markers decreased in the order of CEACAM1 < CA242 < CA19-9 (P<0.05), and the specificity in the order of CA242 < CA19-9 < CEACAM1 (P<0.05).
CONCLUSIONCEACAM1 shows a higher diagnostic sensitivity than CA19-9 and CA242 for pancreatic cancer, but due to its low specificity this marker alone is not sufficient for diagnostic purposes.

OBJECTIVETo study the use of neural network in determining the risk factors of diseases.
METHODSWith back-propagation neural network (BP network) as fitting model based upon data gathered from an epidemiological survey on diabetes mellitus and under the network structure of 22-6-1, the mean impact value (MIV) for each input variables and sequencing the factors according to their absolute MIVs were calculated. The results from BP network with multiple logistic regression analysis and log-linear model for united actions between factors were compared with optimizing Levenberg-Marquardt algorithm.
RESULTSBy BP network analysis, the sequence of importance for the risk factors of diabetes mellitus became: faster pulse, diabetes mellitus family history, living longer in the investigated area, with medical record of nephropathy, having higher ratio for waist-to-hip, being male, with medical records of diseases as hyperlipoproteinmia, coronary heart disease, hypertension, high diastolic pressure, higher income, do no drink alcohol, age, higher systolic pressure, less educated, body mass index, with medical records of other diseases, physical exercise related to jobs smoking, occupation, with medical record for cerebrovascular disease, with medical record for liver disease etc. However, only 7 factors were statistically significant in multiple logistic regression analysis. The sequence of their importance appeared as: pulse, diabetes mellitus family history, the medical record of nephropathy, waist-to-hip ratio, the medical record of hypertension, work-place related exercise and age. The sequences of importance were almost the same between the two while the difference could partly be explained by the interaction among risk factors through log-linear model.
CONCLUSIONNeural network could be used to analyze the risk factors of diseases and could assimilate more complicated relationships (main effects and interactions) between inputs and outputs, better than using the traditional methods.
